    To investigate the feasibility of concurrent chemo radiation in locally advanced carcinoma cervix patients in our clinical setting. From Sept. 1st 2005 to Aug. 31st 2006, 102 patients of carcinoma cervix belonging to stage IIA to IV A were enrolled in the study. External beam radiation therapy was administered using Cobalt 60 teletherapy machine. Cisplatinum (40 mg/m 2) and 5 Fluorouracil (500 mg/m 2 ) continuous infusions with radiotherapy on D2-D5 in first and last 5 # of radiation therapy were administered. Response to treatment and toxicities were monitored and analyzed in 102 patients (50 study group and 52 control group). All 102 patients completed treatment. Out of 50 patients in the study group, 30, 10 and 4 patients had complete, partial and progressive disease, respectively. While out of 52 patients in the control group, 26 had complete and 12 showed partial response. No difference in overall renal, hematological and cutaneous toxicity was seen between two groups. This study did not show any benefit of concurrent chemo radiation as compared to radiotherapy alone in locally advanced cervical cancer patients. This could be due to more bulk of tumor stage per stage, poor nutritional status, less number of patients in both arms, not enough to pick up statistically significant small difference in outcome.

    Ten patients with advanced squamous cell carcinoma of the uterine cervix received induction chemotherapy with cis-platinum, mitomycin-C, vincristine, and bleomycin (BOMP) over a 5 week period, followed by radiotherapy with concomitant weekly cisplatinum. Two patients were FIGO stage I-B barrel-shaped, five were stage II-B, and three were III-B. All patients responded to induction chemotherapy with five complete and five partial responses. At the completion of radiation therapy, nine patients had negative biopsies. One patient never reached a complete response and died of distant metastasis. Another underwent total exenteration for a central recurrence and was found to have microscopic paraaortic lymph node involvement. A third recurred in the parametrium. Two patients with barrel-shaped tumors underwent extrafascial hysterectomies; both had negative specimens and tolerated surgery well. Although follow-up is short, this new approach for advanced carcinoma of the cervix yielded excellent results and was well tolerated.

    To evaluate the potential benefit of proton therapy and photon based intensity-modulated radiotherapy in comparison to 3-D conformal photon radiotherapy (3D-CRT) in locally advanced cervix cancer. In five patients with advanced cervix cancer 3D-CRT (four-field box) was compared with intensity modulated photon (IMXT) and proton therapy (IMPT) as well as proton beam therapy (PT) based on passive scattering. Planning target volumes (PTVs) included primary tumor and pelvic and para-aortic lymph nodes. Dose-volume histograms (DVHs) were analyzed for the PTV and various organs at risk (OARs) (rectal wall, bladder, small bowel, colon, femoral heads, and kidneys). In addition dose conformity, dose inhomogeneity and overall volumes of 50% isodoses were assessed. All plans were comparable concerning PTV parameters. Large differences between photon and proton techniques were seen in volumes of the 50% isodoses and conformity indices. DVH for colon and small bowel were significantly improved with PT and IMPT compared to IMXT, with D(mean) reductions of 50-80%. Doses to kidneys and femoral heads could also be substantially reduced with PT and IMPT. Sparing of rectum and bladder was superior with protons as well but less pronounced. Proton beam RT has significant potential to improve treatment related side effects in the bowel compared to photon beam RT in patients with advanced cervix carcinoma.

    Although the incidence of cancer cervix has reduced in India during the last two decades, still most of the patients presenting in tertiary care centers are in advanced stages. At this center, we see 6% of cancer cervix cases every year, and most of these cases are in stage III and IVa. All these patients have squamous cell carcinoma and were treated with a combination of external and intracavitary radiotherapy along with concurrent cisplatin given once weekly. Eighty-nine point nine % patients had achieved a complete response. Local recurrence was seen in 17.9% at a median duration of 10.5 months, and 8.17% developed distant metastasis involving lung, liver, bone, and supraclavicular lymph nodes. Three patients developed metastasis at unusual sites involving breast, paraspinal muscles, and duodenum which are very rarely involved. These patients were treated with chemotherapy using carboplatin and Paclitaxel combination but succumbed within 8-10 months of development of metastasis. The cause of involvement of these unusual sites is not clear, but it may be hematological spread, and we want to share these reports such that these sites are seen during follow-up of patients of cancer cervix.

    We performed a retrospective analysis of the clinical features and patient outcomes for advanced-stage glassy cell carcinoma of the uterine cervix. The study was restricted to cases in which the glassy cell features constituted at least 95% of the biopsied specimen. During the study period, 675 patients were diagnosed with primary cervical carcinoma. Five (0.7%) of the 675 patients had cervical glassy cell carcinoma; of these, three were premenopausal, and two were postmenopausal. Abnormal vaginal bleeding was the most frequent presenting symptom. Glassy cell carcinoma presented as a fungating, exophytic, or infiltrative mass. The greatest tumor dimension ranged from 3 to 9 cm. All patients had parametrial extension. Four patients had stage IIB tumors, and one had a stage IIIB tumor. All patients received concurrent chemoradiation therapy. The patient with a stage IIIB tumor died of hypovolemic shock caused by upper gastrointestinal bleeding during radiation therapy. Three patients with stage IIB tumors survived for more than 8 years without tumor recurrence or metastasis. One of these three patients died of pelvic recurrence 10 years after the initial diagnosis. Cervical glassy cell carcinoma has traditionally been considered an aggressive, highly malignant tumor with poor prognosis, but our data suggest that patient survival is not significantly decreased compared with other histological types of cervical carcinoma. It will be necessary to analyze patient outcomes using a larger number of cervical glassy cell carcinoma cases to confirm our findings. PMID:27793022

    The purpose of this study was to document whether the technical qualities of a brachytherapy application impacts on the outcome of patients with locally advanced cervix cancer treated by definitive irradiation. A previous report from the patterns of care study demonstrated the importance of brachytherapy in the treatment of locally advanced cervix cancer. Locally advanced disease was defined as FIGO stages Ib (if tumor diameter was < or = 4 cm), IIb (if disease was bilateral or involved the lateral aspect of either parametrium), and III. Localization films from 128 patients with locally advanced squamous cell carcinoma of the cervix were reviewed by a radiation physicist and a radiation oncologist with expertise in gynecologic radiotherapy. All patients received external beam irradiation followed by one brachytherapy application (median point A dose = 8040 cGy; range, 4083-10,020 cGy). Brachytherapy parameters assessed were (a) the distance between the right colpostat source and the distal tandem source, (b) the distance between the left colpostat source and the distal tandem source, and (c) the symmetry of colpostat placement. Implants were scored as "ideal" (n = 8) when all three parameters were deemed satisfactory, "unacceptable" (n = 17) when none of the parameters was deemed satisfactory, and "adequate" (n = 41) in all other cases. Significantly improved 5-year local control was seen when comparing ideal and adequate placements to unacceptable placements (68% vs 34%, P = 0.02). A strong trend toward improved 5-year survival was also noted among the group with ideal and adequate implants as opposed to unacceptable implants (60% vs 40%). Multivariate analysis showed that the technical adequacy of the brachytherapy implant was the most important prognostic discriminant of local control. In conclusion, these analyses demonstrate the direct influence of competent technical implant performance on tumor control and even survival. While only a small fraction of

    Purpose: To study the prognostic value of human papillomavirus (HPV) genotypes in patients with advanced cervical cancer treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). Methods and Materials: Between August 1993 and May 2000, 327 patients with advanced squamous cell carcinoma of the cervix (International Federation of Gynecology and Obstetrics stage III/IVA or stage IIB with positive lymph nodes) were eligible for this study. HPV genotypes were determined using the Easychip Registered-Sign HPV genechip. Outcomes were analyzed using Kaplan-Meier survival analysis and the Cox proportional hazards model. Results: We detected 22 HPV genotypes in 323 (98.8%) patients. The leading 4 types were HPV16, 58, 18, and 33. The 5-year overall and disease-specific survival estimates for the entire cohort were 41.9% and 51.4%, respectively. CCRT improved the 5-year disease-specific survival by an absolute 9.8%, but this was not statistically significant (P=.089). There was a significant improvement in disease-specific survival in the CCRT group for HPV18-positive (60.9% vs 30.4%, P=.019) and HPV58-positive (69.3% vs 48.9%, P=.026) patients compared with the RT alone group. In contrast, the differences in survival with CCRT compared with RT alone in the HPV16-positive and HPV-33 positive subgroups were not statistically significant (P=.86 and P=.53, respectively). An improved disease-specific survival was observed for CCRT treated patients infected with both HPV16 and HPV18, but these differenced also were not statistically significant. Conclusions: The HPV genotype may be a useful predictive factor for the effect of CCRT in patients with advanced squamous cell carcinoma of the cervix. Verifying these results in prospective trials could have an impact on tailoring future treatment based on HPV genotype.

    The simultaneous occurrence of carcinoma of the cervix and pelvic kidney is rare. As the pelvic kidney occupies the conventional radiation portal for carcinoma of the cervix, treatment of these patients with radiation presents a therapeutic challenge. A 48-year-old stage IIIB cervical carcinoma patient with an incidental diagnosis of pelvic kidney was treated with radical chemoradiotherapy using intensity-modulated radiotherapy with concurrent weekly cisplatin, followed by intracavitary radiotherapy. The bilateral kidney dose was restricted within a tolerance limit of 16.6 Gy. At the 18-month follow-up, the patient was disease free and had no deterioration in kidney function. Intensity-modulated radiotherapy provided the necessary means for delivering radical radiation doses in this case scenario with adequate sparing of the kidney. © 2016 Japan Society of Obstetrics and Gynecology.

    Small cell neuroendocrine carcinoma of uterine cervix is a rare variant of cervical carcinoma with features of high aggressiveness. It is difficult to manage these tumors. It is often diagnosed at an advanced stage and its prognosis is generally poor. The present report describes a 65 year old woman who presented with postmenopausal bleeding and had a friable polypoidal growth hanging from the cervix. Microscopic examination of the growth showed features of small cell carcinoma. Neuroendocrine cellular characteristics were assessed by using antibodies against neuron specific enolase. The case is being reported to create awareness of this rare entity

    Purpose: To evaluate the toxicity and efficacy of carbon ion radiotherapy (CIRT) for locally advanced cervical cancer by two phase I/II clinical trials. Methods and Materials: Between June 1995 and January 2000, 44 patients were treated with CIRT. Thirty patients had Stage IIIB disease, and 14 patients had Stage IVA disease. Median tumor size was 6.5 cm (range, 4.2-11.0 cm). The treatment consisted of 16 fractions of whole pelvic irradiation and 8 fractions of local boost. In the first study, the total dose ranged from 52.8 to 72.0 gray equivalents (GyE) (2.2-3.0 GyE per fraction). In the second study, the whole pelvic dose was fixed at 44.8 GyE, and an additional 24.0 or 28.0 GyE was given to the cervical tumor (total dose, 68.8 or 72.8 GyE). Results: No patient developed severe acute toxicity. In contrast, 8 patients developed major late gastrointestinal complications. The doses resulting in major complications were {>=}60 GyE. All patients with major complications were surgically salvaged. The 5-year local control rate for patients in the first and second studies was 45% and 79%, respectively. When treated with {>=}62.4 GyE, the local control was favorable even for the patients with stage IVA disease (69%) or for those with tumors {>=}6.0 cm (64%). Conclusions: In CIRT for advanced cervical cancer, the dose to the intestines should be limited to <60 GyE to avoid major complications. Although the number of patients in this study was small, the results support continued investigation to confirm therapeutic efficacy.

    The purpose of this study was to evaluate the early and late radiotherapeutic morbidity after combined external and intracavitary radiotherapy to the uterine cervix. Early morbidity was most frequently seen in the rectosigmoideum (61%) and urinary bladder (27%). Medication for early morbidity was required 68% and hospitalization in 10% of the patients. The frequencies of each late morbidity grade did not differ in relation to FIGO State while the actuarial estimates increased significantly with increasing stage. This reflects the poor prognosis in the more advanced stages, where few patients survived to develop late morbidity, and also points to the importance of latency in reporting late radiotherapeutic morbidity. In Stage IVA patients, the ratios between the actuarial estimate and the frequency of late severe rectosigmoid and urinary bladder morbidity were as high as 2.5 and 3, respectively. The highest 5-year risk ({+-} 1 SE of the estimate) of late severe morbidity were found for the rectosignoideum (28% {+-} 3), small intestine (13% {+-} 2) and urinary bladder (10% {+-} 2). Rectosigmoid and urinary bladder complications constituted the most important part of the combined organ morbidity. Almost half of the patients developing late moderate rectosigmoid and one-third of those developing late moderate bladder complications, did so within one year after radiotherapy. Almost all complications were developed within 3 to 4 years after radiotherapy. The probability of surviving without recurrence and/or severe combined rectosigmoid and urinary bladder morbidity was low (23% {+-} 2). Actuarial estimates rather than frequencies should be reported to avoid underestimation of the risk of late radiotherapeutic morbidity in long-term survivors. 29 refs., 5 figs. 7 tabs.

    Different patterns of invasion (PIs) have prognostic impact in several types of cancer and are associated with different grades of peritumoral stromal remodeling, characterized by the desmoplastic stromal response (DSR). One key regulator influencing cellular motility and peritumoral stromal response is c-met/HGF. This study evaluates the association between different PI, peritumoral DSR and its correlation to the expression of c-met/HGF in squamous cell carcinomas of the uterine cervix (CX). 131 advanced stage CX (FIGO III/IV) were re-evaluated histologically regarding PI, using a two-level scoring system. The tumor grows in solid cords/trabeculae in finger-like PI and in very small groups or single cells in spray-like PI. DSR was categorized as none/weak and moderate/strong. The tumors were stained with antibodies against c-met and HGF. The staining of >30% of tumor cells was defined as overexpression. The PI was correlated to the prognostic outcome, different categories of DSR and expression status of c-met and HGF. 66.4% of the tumors showed a finger-like, and 33.6% a spray-like PI. The spray-like PI showed a reduced two-year overall survival when compared to the finger-like PI (14.0% vs. 29.1%, respectively; p=0.012), and was associated with moderate/strong DSR. The majority of the tumors showed overexpression of c-met (85.4%) and HGF (74.8%). There was no correlation between the expression status of c-met/HGF and the FIGO stage, peritumoral DSR or the prognostic outcome. Spray-like PI is of prognostic impact in cervical carcinoma FIGO III/IV and is associated with strong peritumoral stromal remodeling. There is no prognostic impact of the immunohistochemical expression of c-met/HGF in advanced stage cervical carcinomas. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Concurrent chemoradiation followed by brachytherapy is currently the standard treatment for locally advanced cervix carcinomas. Modern radiation techniques require planning based on 3D images, and therefore an accurate delineation of target volumes. The clinical target volume (CTV) used for the different phases of treatment are now well defined, but are not always easy to delineate on a CT scan which is currently the standard examination for simulation in radiotherapy. MRI and PET-CT are routinely performed at diagnosis, and can be used to improve the accuracy of the delineation. The objective of this review is to describe the definitions and recommendations of CTV in the treatment of cervical cancer.

    Purpose: To evaluate the efficacy and toxicity of ifosfamide and cisplatin administered concomitantly with low-dose-rate brachytherapy followed by consolidation chemotherapy in the treatment of locally advanced squamous cell cervical carcinoma (LASCC). Methods and materials: Forty-four patients with biopsy-proven LASCC were enrolled. FIGO Stages IB2 bulky to IVA were entered into this study. Patients were assigned to receive external radiotherapy (50 Gy in 25 fractions); then ifosfamide 2 g/m{sup 2} plus cisplatin 75 mg/m{sup 2} was applied during two low-dose-rate brachytherapy applications, and 4 cycles of consolidation chemotherapy with the same drug combination were given after completion of radiotherapy. The planned dose to point A was 85 Gy. Results: All patients received both courses of concomitant chemobrachytherapy and at least 1 cycle of consolidation chemotherapy. The average duration of radiation was 45.1 days. The clinical complete response rate was 100%. Grade 3 and 4 leukopenia occurred in 25% and 11% of the cycles, respectively. After a median follow-up of 34 months (range, 20-54 months), the recurrence-free and the overall survival rates were 84% and 91%, respectively. Major delayed local complications occurred in 7 cases (16%). Conclusions: These results indicate that concomitant chemobrachyradiotherapy with ifosfamide and cisplatin is a feasible combination for patients with LASCC of the cervix uteri. A randomized trial is planned.

    Disclosed is an apparatus for treating carcinoma of the uterine cervix by judiciously applying radioactive material immediately adjacent the uterine cervix for an extended period of time empirically determined by the radiologist. The novel apparatus comprises three radioactively chargeable components including a central tubular tandem vaginally insertable longitudinally into the uterine cervix and two non-lineal tubular ovoidal assemblies longitudinally locatable at the cervix and positioned laterally between the respective vaginal walls and the uterine cervix. The ovoidal assemblies are conveniently removably and pivotably connected to the central tandem component externally of the vaginal along the sagittal plane through a novel adapter member whereby the radioactively chargeable ovoidal assemblies tend to remain within a laterally extending plane located substantially midway the transversely separated vasicovaginal and rectovaginal septa, even though the patient periodically shifts her reclining posture during the extended treatment by said vaginally protruding apparatus.

    Purpose This report presents the 2011 update to the American Brachytherapy Society (ABS) high-dose-rate (HDR) brachytherapy guidelines for locally advanced cervical cancer. Methods Members of the American Brachytherapy Society (ABS) with expertise in cervical cancer brachytherapy formulated updated guidelines for HDR brachytherapy using tandem and ring, ovoids, cylinder or interstitial applicators for locally advanced cervical cancer were revised based on medical evidence in the literature and input of clinical experts in gynecologic brachytherapy. Results The Cervical Cancer Committee for Guideline Development affirms the essential curative role of tandem-based brachytherapy in the management of locally advanced cervical cancer. Proper applicator selection, insertion, and imaging are fundamental aspects of the procedure. Three-dimensional imaging with magnetic resonance or computed tomography or radiographic imaging may be used for treatment planning. Dosimetry must be performed after each insertion prior to treatment delivery. Applicator placement, dose specification and dose fractionation must be documented, quality assurance measures must be performed, and follow-up information must be obtained. A variety of dose/fractionation schedules and methods for integrating brachytherapy with external-beam radiation exist. The recommended tumor dose in 2 Gray (Gy) per fraction radiobiologic equivalence (EQD2) is 80–90 Gy, depending on tumor size at the time of brachytherapy. Dose limits for normal tissues are discussed. Conclusion These guidelines update those of 2000 and provide a comprehensive description of HDR cervical cancer brachytherapy in 2011. PMID:22265437

    Small cell carcinoma of the cervix is a rare and a very aggressive tumour. Once being considered to be a rare type of squamous cell carcinoma, evidence has proven that most of the tumours express one or more markers of neuroendocrine differentiation. The behaviour of this rare malignancy is different from that of squamous cell carcinomas, with a high propensity for nodal and distant metastases. Hence, there is a need to highlight this histopathological entity. PMID:24701511

    To evaluate the toxicity and clinical outcome in patients with locally advanced cervical cancer (LACC) treated with whole pelvic conventional radiation therapy (WP-CRT) versus intensity modulated radiation therapy (WP-IMRT). Between January 2010 and January 2012, 44 patients with International Federation of Gynecology and Obstetrics (FIGO 2009) stage IIB-IIIB squamous cell carcinoma of the cervix were randomized to receive 50.4 Gy in 28 fractions delivered via either WP-CRT or WP-IMRT with concurrent weekly cisplatin 40 mg/m(2). Acute toxicity was graded according to the Common Terminology Criteria for Adverse Events, version 3.0, and late toxicity was graded according to the Radiation Therapy Oncology Group system. The primary and secondary endpoints were acute gastrointestinal toxicity and disease-free survival, respectively. Of 44 patients, 22 patients received WP-CRT and 22 received WP-IMRT. In the WP-CRT arm, 13 patients had stage IIB disease and 9 had stage IIIB disease; in the IMRT arm, 12 patients had stage IIB disease and 10 had stage IIIB disease. The median follow-up time in the WP-CRT arm was 21.7 months (range, 10.7-37.4 months), and in the WP-IMRT arm it was 21.6 months (range, 7.7-34.4 months). At 27 months, disease-free survival was 79.4% in the WP-CRT group versus 60% in the WP-IMRT group (P=.651), and overall survival was 76% in the WP-CRT group versus 85.7% in the WP-IMRT group (P=.645). Patients in the WP-IMRT arm experienced significantly fewer grade ≥2 acute gastrointestinal toxicities (31.8% vs 63.6%, P=.034) and grade ≥3 gastrointestinal toxicities (4.5% vs 27.3%, P=.047) than did patients receiving WP-CRT and had less chronic gastrointestinal toxicity (13.6% vs 50%, P=.011). WP-IMRT is associated with significantly less toxicity compared with WP-CRT and has a comparable clinical outcome. Further studies with larger sample sizes and longer follow-up times are warranted to justify its use in routine clinical practice. Copyright © 2013

Patients in the WP-IMRT arm experienced significantly fewer grade ≥2 acute gastrointestinal toxicities (31.8% vs 63.6%, P=.034) and grade ≥3 gastrointestinal toxicities (4.5% vs 27.3%, P=.047) than did patients receiving WP-CRT and had less chronic gastrointestinal toxicity (13.6% vs 50%, P=.011). Conclusion: WP-IMRT is associated with significantly less toxicity compared with WP-CRT and has a comparable clinical outcome. Further studies with larger sample sizes and longer follow-up times are warranted to justify

    A 42-year-old woman developed lower extremity weakness and sensory loss 1 year after external and intracavitary radiotherapy for Stage IB carcinoma of cervix. She has been followed for 5 years posttreatment, and the neurologic abnormalities have persisted, but no evidence of recurrent carcinoma has been found. We believe this to be a rare case of sacral plexus radiculopathy developing as a late complication after radiotherapy. Suggestions are made for improving the radiotherapy technique to prevent this complication in future cases.

    We carried out a case-control study of 217 cases of in situ carcinoma of the uterine cervix and 243 controls chosen from the general population of Utah. We found a relative risk of 3.0 for cigarette smoking after controlling for sexual and socioeconomic risk factors. The smoking association was strongest in the youngest age group (ages 20-29), reaching seventeenfold, and was weaker in the older age groups. These data suggest that cigarette smoking may be an independent risk factor for cancer of the uterine cervix, after considering sexual behavior and other well-established risk factors. PMID:6837821

    Cervix cancer is the second most common cancer among women worldwide, whereas paclitaxel, the first line chemotherapeutic drug used to treat cervical cancer, shows low chemosensitivity on the advanced cervical cancer cell line. Tanshinone IIA (Tan IIA) exhibited strong growth inhibitory effect on CaSki cells (IC50 = 5.51 μM) through promoting caspase cascades with concomitant upregulating the phosphorylation of p38 and JNK signaling. Comprehensive proteomics revealed the global protein changes and the network analysis implied that Tan IIA treatment would activate ER stress pathways that finally lead to apoptotic cell death. Moreover, ER stress inhibitor could alleviate Tan IIA caused cell growth inhibition and ameliorate C/EBP-homologous protein as well as apoptosis signal-regulating kinase 1 mediated cell death. The therapeutic interventions targeting the mitochondrial-related apoptosis and ER stress responses might be promising strategies to conquer paclitaxel resistance.

    To quantitatively describe the involution and mobility of carcinoma of the cervix while under treatment with chemoradiotherapy (both with external beam radiation [EBRT] and high-dose-rate [HDR] intracavitary therapy). These data have implications for conformal or intensity modulated radiation therapy boost to the cervix. Seventeen patients underwent HDR brachytherapy boost to the cervix and were evaluated by repeat clinical examinations. In most cases, 5 weekly HDR brachytherapy insertions were performed after approximately 2 to 3 weeks of the initiation of EBRT. Sequential clinical tumor sizes were recorded in the chart for each patient under treatment. Linear regression analyses were performed to analyze tumor size as a function of total dose of external beam plus brachytherapy and number of elapsed days during the treatment course. In addition, the mobility of the cervix was documented by placement of a uterine sleeve for HDR brachytherapy before the initiation of therapy, and changes in sleeve position were identified on portal films relative to the midline of the pubic symphysis, in three dimensions. The anatomic position of the cervix was also identified at the time of simulation for HDR brachytherapy. Seventeen patients were identified and selected to receive HDR brachytherapy at our institution. Sixteen of the 17 patients received concurrent chemotherapy. The median dose at which tumor was no longer clinically evident was 61.5 Gy (95% confidence interval [CI]: 50.7-72.3 Gy) by linear regression analysis. This indicates that the median dose to achieve a 50% reduction in tumor size is approximately 30.8 Gy. Similarly, the median number of elapsed days for a complete response was 42 days (95% CI: 34-50 elapsed days). This indicates that it takes 21 days to achieve a 50% clinical complete response for patients undergoing concurrent cisplatin-based chemoradiotherapy and HDR brachytherapy. In addition, the mobility of the cervix during EBRT was noted by serial

    Cancer of the cervix is amenable to treatment provided it is diagnosed at the preinvasive stage, and it is therefore imperative to be able to identify cases of symptomless cervical cancer, which invariably presents no visible alteration in the appearance of the mucous membrane. Fortunately, this is possible by study of vaginal smears for exfoliated cells. In view of the ease with which carcinoma of the uterine cervix can be induced in mice and of its similarity to analogous lesions in women, it was thought that study of early cytological and morphological changes in cervical carcinoma of the mouse—especially at the in situ stage—might prove valuable for biological and therapeutic studies of human cervical carcinoma. This paper reports on study of the progressive epithelial changes in the mouse cervix by means of exfoliated cells in vaginal smears and histological examination of the cervical epithelium after intravaginal painting with 3,4-benzpyrene. The authors consider that basal cell hyperplasia and the early grades of dysplasia are reversible if the carcinogenic agent is withdrawn, but that the lesion is likely to be invasive and progressive once the presence of large numbers of squamoid cells indicates that the dysplastic changes involve the superficial layers.

    Verrucous carcinoma is a rare variant of epidermoid carcinoma with distinct clinical and histopathologic features. To date, 31 cases have been reported in the cervix. They are typically slow-growing, locally invasive tumors with low potential for lymphatic metastasis and appear to be radioresistant. We report a case which is unusual in having endometrial and deep myometrial invasion. Electron microscopy, immunohistochemical stains, and DNA in situ hybridization studies failed to detect human papilloma virus particles but the oncogenic potential of the virus is not excluded.

    A review of 203 patients with adenocarcinoma of the cervix treated at the University of Michigan Medical Center from 1970-1985 is reported. The following subtypes were identified: endocervical, 94 (46%); adenosquamous, 67 (33%); papillary, 21 (11%); clear cell, 16 (8%); and mucoid, five (4%). The distribution by stage of disease included stage I, 125 (62%); stage II, 40 (20%); stage III, 25 (12%); and stage IV, 13 (6%). One patient was lost to follow-up. Overall, 107 patients (53%) died from disease. The cumulative 5-year survival rate varied significantly according to the following: stage of disease--stage I 60%, stage II 47%, stage III 8%, stage IV 0%; tumor grade--well-differentiated 75%, moderately differentiated 57%, poorly differentiated 29%; lymph node status--negative nodes 79%, positive nodes 12%; patient age--less than 40 years 65%, 40-60 years 46%, over 60 years 30%; and interval from previous pelvic examination--within 1 year 65%, 1-3 years 41%, beyond 3 years 36%. The histologic subtype did not significantly influence survival. Treatment strategies should be directed at high-risk groups as defined by the stage of disease, tumor differentiation, and lymph node status.

    The human uterine cervix carcinoma is one of the most well-known malignancy reproductive system cancers, which threatens women health globally. However, the mechanisms of the oncogenesis and development process of cervix carcinoma are not yet fully understood. Long non-coding RNAs (lncRNAs) have been proved to play key roles in various biological processes, especially development of cancer. The function and mechanism of lncRNAs on cervix carcinoma is still rarely reported. We selected 3 cervix cancer and normal cervix tissues separately, then performed lncRNA microarray to detect the differentially expressed lncRNAs. Subsequently, we explored the potential function of these dysregulated lncRNAs through online bioinformatics databases. Finally, quantity real-time PCR was carried out to confirm the expression levels of these dysregulated lncRNAs in cervix cancer and normal tissues. We uncovered the profiles of differentially expressed lncRNAs between normal and cervix carcinoma tissues by using the microarray techniques, and found 1622 upregulated and 3026 downregulated lncRNAs (fold-change>2.0) in cervix carcinoma compared to the normal cervical tissue. Furthermore, we found HOXA11-AS might participate in cervix carcinogenesis by regulating HOXA11, which is involved in regulating biological processes of cervix cancer. This study afforded expression profiles of lncRNAs between cervix carcinoma tissue and normal cervical tissue, which could provide database for further research about the function and mechanism of key-lncRNAs in cervix carcinoma, and might be helpful to explore potential diagnosis factors and therapeutic targets for cervix carcinoma.

It is estimated that 10% of patients with small-cell lung cancer have syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and hyponatremia has been reported to be significantly associated with a poor prognosis. A proportion of small cell carcinoma of the uterine cervix exhibit neuroendocrine characteristics as revealed by immunohistochemistry, However, cases presenting typical symptoms due to SIADH are extremely rare. This report of the SIADH of the uterine cervix is a rare case in the small cell carcinoma of the cervix presenting with tumor-associated paraneoplastic syndrome.

    Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is exceedingly uncommon. We herein report a rare case of cervical LELC. A 45-year-old woman was admitted to gynecology department with vaginal bleeding for one month. Liquid-based cytology revealed atypical endometrial cells, not otherwise specified on her cervix. On a hysteroscopy, an endocervical mass was identified and the pathologic result was consistent with poorly differentiated squamous cell carcinoma. Magnetic resonance imaging and positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-D-glucose integrated with computed tomography revealed a 3.1-cm endocervical mass without distant metastasis or enlarged lymph nodes. The International Federation of Gynecology and Obstetrics stage was IB1. A radical hysterectomy and bilateral pelvic lymph node dissection were performed. The pathologic diagnosis was a poorly differentiated carcinoma, showing features of LELC. She has been followed for 8 months without adjuvant treatment since the surgery, during which time there has been no evidence of tumor recurrence or metastasis. PMID:28217683

    Between January 1959 and December 1986, 10 of 328 patients (3%) treated with curative intent using primary radiation therapy for carcinoma of the cervix developed obstructive ureteropathy due to fibrosis. The mean age of the patients with obstructive ureteropathy was 45 years and the median time to obstruction was 26 months. The obstruction was unilateral in 8 cases and involved the parametrial portion of the ureter in at least 5 cases. No predisposing risk factor was found to be associated with the development of obstructive ureteropathy. After corrective surgery, renal function remained normal in 8 patients, and resolution of the hydronephrosis occurred in 4 patients.

    Purpose: To evaluate the efficacy and toxicities of concurrent chemoradiotherapy (CCRT) and consolidation chemotherapy in patients with locally advanced squamous cell cervical carcinoma. Methods and Materials: Patients with LASCC (FIGO Stage IIB-IIIB) were treated with pelvic external beam radiotherapy (45 Gy for Stage IIB and 50 Gy for Stage III) and high-dose-rate intracavitary brachytherapy (50 Gy for Stage IIB and 35 Gy for Stage III). The cumulative dose at point A was 50 Gy for Stage IIB and 65 Gy for Stage III. Concurrent chemotherapy with paclitaxel (35 mg/m{sup 2}) and nedaplatin (20 mg/m{sup 2}) was given every week for 6 weeks. Consolidation chemotherapy with paclitaxel (135 mg/m{sup 2}) and nedaplatin (60 mg/m{sup 2}) was administered every 3 weeks for 4 cycles. Results: All patients completed CCRT, and 28 of 34 patients completed consolidation chemotherapy. The complete response rate was 88% (95% CI, 73-96%). The most common Grade 3 or higher toxicities were leukopenia/neutropenia (10.9% of the cycles). During a median follow up of 23 months (range, 14-30 months), 5 patients had locoregional failure and 1 patient had distant metastasis. The estimated 2-year progression-free survival and overall survival were 82% (95% CI, 68-95%) and 93% (95% CI, 83-100%), respectively. Grade 3 late complications occurred in 3 patients (9%). Conclusions: CCRT with paclitaxel and nedaplatin followed by consolidation chemotherapy is well tolerated and effective in patients with locally advanced squamous cell cervical carcinoma. Further randomized trials of comparing this regimen with the standard treatment are worth while.

    Because the greater number of viral cervical lesions, the authors recall their cytological and pathological pictures. In 30% of the causes, they have observed relations between flat condylomas and cervical severe dysplasias and carcinoma in situ. But in these last lesions, the cytological characters of the viral infestations are not visuable. The relationship between condyloma and carcinoma in situ is explained by the virus modifications on the germinative cells genoma which enhance great multiplication of these cells and inhibit the epidermoid differentiation. When the virus are not very active, or the host responses sufficient, the cell differentiation and maturation permit the replication of the virus and its appearance in the cytoplasm of the superficial cells. The authors stress on the complete destruction of the viral cervical lesions and the later control of the cervix.

    From January 1, 1946, through January 1, 1986, at the University of Michigan, 60 patients were treated with Stage IB (FIGO) carcinoma of the cervix with lymph node metastases. Clinical variables were examined with regard to long-term survival. Prognostically significant variables were (1) highest level of lymph node involvement and (2) tumor histology. Patients with common iliac or periaortic node involvement had an actuarial survival at 5 years of 14%; 5-year survival for patients with only pelvic node involvement (external iliac, hypogastric, or obturator) was 68%. Patients with adenocarcinoma or adenosquamous histology had an actuarial survival at 5 years of 16%; 5-year survival for patient with squamous cell carcinoma was 71%. Overall survival for all patients with lymph node involvement was 61%. For patients undergoing radical hysterectomy as primary treatment, postoperative adjuvant radiotherapy did not significantly improve survival.

    Bryostatin-1 is a macrocyclic lactone that has been shown to regulate protein kinase C (PKC) activity and thereby potentially inhibit tumor invasion, angiogenesis, cell adhesion, and multidrug resistance. In preclinical experiments, bryostatin-1 induces tumor growth inhibition and enhances cytotoxicity when combined with other agents including cisplatin in cervical cancer cells. It was therefore anticipated that combination bryostatin-1-cisplatin therapy would be effective in patients with cervical cancer. The current study was conducted to evaluate this therapeutic approach in patients with recurrent or advanced-stage cervical carcinoma. An IRB-approved New York Gynecologic Oncology Group (NYGOG) trial was activated for patients with a histological diagnosis of metastatic cervical cancer or in patients with recurrent disease not eligible for surgery or radiation. Enrolled patients received bryostatin-1 (50-65 microg/m(2)) as a 1-h infusion followed by cisplatin (50 mg/m(2)). The combined treatment was administered every 21 days. Fourteen patients were enrolled. The majority of patients had squamous cell carcinoma. Ten out of fourteen patients had recurrent disease. Fifty percent of the patients received bryostatin at 50 microg/m(2) and 50% received bryostatin at 65 microg/m(2). Seventy-one percent completed two cycles of treatment. The most common grade II-III toxicities were myalgia, anemia, and nausea or vomiting. One patient developed a hypersensitivity reaction and one developed grade III nephrotoxicity. Seventy-one percent (10/14) of patients were evaluated for tumor response. Eight out of ten (80%) of patients had progressive disease and 2/10 (20%) had stable disease. There were no treatment responses. Despite promising preclinical data, this clinical trial indicates that the combination of cisplatin and bryostatin-1 at the doses and schedule used is not effective in patients with advanced-stage or recurrent cervical cancer. There is even the possibility of

    This is a retrospective analysis of 148 patients with histologically proven carcinoma of the cervix, stage III, treated with irradiation. All patients received external irradiation with cobalt 60 followed by intracavitary radium application. The median age was 55 years. Squamous cell carcinoma was found in 96.5% of the cases. The 8-year actuarial survival rate was 41%. Bilateral parametrial invasion proved to be a strong prognostic factor. Patients with unilateral disease had a survival rate of 43% whereas in those with bilateral involvement it was only 15% (P less than 0.005). The total pelvic failure rate was 29.5%. The overall incidence of distant metastasis was 11%. The complication rate (minor and major complications) was high, with vaginal stenosis (22.5%), proctitis (21.5%), cystitis (13.5%), and fistulae (4%) occurring in 33, 32, 20, and 6 patients, respectively. New treatment modalities are urgently needed for advanced carcinoma of the cervix. Bilateral parametrial involvement is an unfavorable prognostic factor and this should be kept in mind when designing new protocols.

    To investigate whether age is a prognostic factor in patients with carcinoma of the cervix, a retrospective study was undertaken of 261 patients, aged 45 years or less, who were referred to the Rotterdamsch Radio-Therapeutisch Instituut (RRTI) between 1973 and 1982. Patients were referred for either primary treatment--surgery or radiotherapy--or for adjuvant radiotherapy. Overall 5-year survival figures were rather low, which may be explained by negative patient selection as the RRTI is a referral hospital: stage IB, 72%; stage IIA; 61%; stage IIB; 52%; stage III; 29%. A particular poor survival was noted for patients (n = 22) aged 28 or less. Overall 5-year survival of these patients was only 39% in contrast to 67% 5-year survival of older patients. This difference was highly significant (p less than 0.002). Even if corrected for stage, very young patients had a poorer prognosis (stage IB: 45% versus 75% 5-year survival of older patients). Within the older age group, no trend towards a better prognosis with increasing age could be identified. As a treatment was similar for all patients, no explanation is available for this observation.

    Concentrations of total sialic acid (TSA) and lipid-bound sialic acid (LSA) were determined in serum samples from 88 patients with squamous cell carcinoma of the cervix, 26 normal subjects, and 44 patients with benign uterine or ovarian disease. TSA concentrations in patients with cervical cancer were found to correlate with advanced-stage disease. LSA concentrations were only increased in stage IV of the disease. Sensitivity of the test for stage IB was zero for TSA and 27% for LSA. The specificity of both markers was about 80% due to a low incidence of false-positive values in the pathologic control group. Measurements of TSA or LSA appear to be of no value for the early detection of cervical cancer or to complement the clinical staging of this tumor.

    Survival of patients with locally advanced carcinoma cervix (LACC) using the current standard of concurrent chemo-radiotherapy (CCRT) has reached a plateau over the last two decades. Loco-regional failure in first two years of treatment completion and distant metastasis in the subsequent years has put the survival curves at a halt. Strategies of induction and adjuvant chemotherapy have yielded little as has any advancement in techniques of delivery of radiation therapy. This article aims at discussing the current existing literature as well as promising novel strategies to enhance radiotherapeutic outcomes in carcinoma of the uterine cervix. The review of English literature included phase I-III trials evaluating either a novel agent, novel application/modifications of an existing treatment regimen or an innovative treatment technique. The studies have been divided in to subsections with summary of most important findings at the end of each section. Despite CCRT being the 'gold standard' treatment, several issues like optimum drug combination, schedule of drug delivery, combination with molecular targeted agents etc. remain undefined. Taxane, topoisomerase and gemcitabine based regimen needs to be further explored and compared with cisplatin based CCRT regimen. Several approaches like local delivery of cytotoxic agents, use of nano-medicine with CCRT are appearing on horizon with promises for the future. Therapies need to be designed based on the human papillomavirus titers of the patients and incorporation of radiosensitizers as an effective way of palliation with short course of radiotherapy may further enhance the radiotherapeutic outcomes. The results of the studies with novel agents and treatment techniques appear promising. Further research in this arena including incorporation of cost-effectiveness analysis and quality of life issues in future trial designs are warranted.

    the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

    Purpose: To study the outcomes of patients with adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix primarily treated with radiotherapy (RT), identify the prognostic factors, and evaluate the efficacy of concurrent chemoradiotherapy (CCRT) or salvage surgery. Methods and Materials: A total of 148 patients with Stage I-IVA AC/ASC of cervix after full-course definitive RT were included. Of the 148 patients, 77% had advanced stage disease. Treatment failure was categorized as either distant or local failure. Local failure was further separated into persistent tumor or local relapse after complete remission. The effectiveness of CCRT with cisplatin and/or paclitaxel was examined, and the surgical salvage rate for local failure was reviewed. Results: The 5-year relapse-free survival rate was 68%, 38%, 49%, 30%, and 0% for those with Stage IB/IIA nonbulky, IB/IIA bulky, IIB, III, and IVA disease, respectively, and appeared inferior to that of those with squamous cell carcinoma of the cervix treated using the same RT protocol. Incomplete tumor regression after RT, a low hemoglobin level, and positive lymph node metastasis were independent poor prognostic factors for relapse-free survival. CCRT with weekly cisplatinum did not improve the outcome for our AC/ASC patients. Salvage surgery rescued 30% of patients with persistent disease. Conclusion: Patients with AC/ASC of the cervix primarily treated with RT had inferior outcomes compared to those with squamous cell carcinoma. Incomplete tumor regression after RT was the most important prognostic factor for local failure. Salvage surgery for patients with persistent tumor should be encouraged for selected patients. Our results did not demonstrate a benefit of CCRT with cisplatin for this disease.

    Purpose: Squamous cell carcinoma antigen (SCC Ag) is a serum biomarker for squamous cell carcinoma (SCC) of the cervix. We investigated the prognostic significance of SCC Ag levels before and at the completion of chemoradiotherapy and compared these levels with the results of pre- and posttreatment positron emission tomography/computed tomography (PET/CT) using [{sup 18}F]fluorodeoxyglucose (FDG). Methods and Materials: The records of 63 women who underwent definitive chemoradiotherapy for SCC of the cervix were reviewed. SCC Ag levels were obtained before and at the completion of radiotherapy. Patients were divided into two groups on the basis of their pretreatment SCC Ag level (>30 ng/mL vs. {<=}30 ng/mL). Pre- and posttreatment FDG-PET/CT characteristics and progression-free survival (PFS) were analyzed according to SCC Ag groups. Results: Median follow-up was 12 months. Women with SCC Ag >30 ng/mL at diagnosis had more advanced lymph node disease on pretreatment FDG-PET/CT than those with SCC Ag {<=}30 ng/mL (p = .002). Women whose SCC Ag normalized at the completion of chemoradiotherapy were more likely to have a complete metabolic response on their 3-month posttreatment FDG-PET/CT than those whose SCC Ag did not normalize (p = .006). The 2-year PFS was 73% for patients with a SCC Ag level {<=}30 ng/mL at diagnosis compared with 0% for those with a SCC Ag level >30 ng/mL at diagnosis (p < .0001). The 2-year PFS was 62% for patients whose SCC Ag normalized at the completion of chemoradiotherapy compared with 0% for those whose SCC Ag did not normalize (p = .0004). Conclusion: Elevated SCC Ag at diagnosis and failure of the SCC Ag to normalize at the completion of treatment are associated with incomplete metabolic response and decreased PFS.

    To assess the significance of social factors as risk factors for carcinoma cervix and to determine the significance of blood group to prevalence of carcinoma cervix in a semi-urban population of Kolar, Karnataka, India. One hundred cases of carcinoma cervix were included in the study, along with 200 females of the same ages considered as controls. Case details were collected from the hospital record section regarding social factors and blood groups and the data were analyzed by descriptive statistical methods. Blood group B showed the highest number of cases (55 cases) followed by blood group O (29 cases) in carcinoma cervix which was statistically significant (p<0.001). Age of marriage between 11 to 20 years showed highest number of carcinoma cervix cases (77 cases) and this also was statistically significant (p<0.001). Patients with rural background were 75 (p=0.112, odds ratio: 1.54), parity of more than or equal to two constituted 96 cases (p=0.006, odds ratio: 4.07) and Hindu patients were 95 in number (p=0.220, odds ratio: 1.89). Blood group B and age of marriage between 11 and 20 years were significantly associated with carcinoma cervix in our population. Region of residence, parity and religion presented with a altered risk for carcinoma cervix.

    The presence of intracavitary cardiac metastasis from squamous cell carcinoma of the uterine cervix is extremely rare. The diagnosis is made almost exclusively postmortem. Apart from causing intracardiac obstruction, it can present as pulmonary emboli and the prognosis is extremely poor. It is important to suspect this diagnosis in patient with recurrent pulmonary emboli. Due to the rarity of this condition it is very difficult to standardize care for these patients. However, it is possible that aggressive therapy may lengthen patients' survival and quality of life. We present a case of isolated intracavitary cardiac metastasis arising from a squamous cell carcinoma of the cervix, 44-year-old woman, diagnosed as stage complaint of fatigue and dyspnea on mild exertion. The echocardiogram showed a mass in the right ventricle and suspicious pulmonary embolism. We took an aggressive therapeutic approach. The pathological examination of the resected tissue revealed metastatic squamous cell carcinoma. PMID:28217685

    To investigate the relationship between apoptosis and histologic types in invasive squamous cell carcinoma and adenocarcinoma of the uterine cervix. The present study involved the assessment of surgical specimens from 74 women with cervical carcinomas FIGO stage IB1 (54 squamous cell carcinomas and 20 adenocarcinomas). The study samples were obtained from selected paraffin blocks containing specimens from patients submitted to surgical procedures. The respective medical charts of patients were reviewed and epidemiologic, clinical and disease-related data were collected. Cervical specimens were assessed by the immunohistochemistry technique using the Bcl-2 protein as a marker. The reactions were considered positive when the cells became stained in brown color. Bcl-2 positive cells were counted in 10 fields under a high magnification (400x) using light microscopy, in the slides area containing squamous carcinoma and adenocarcinoma of the cervix. The total cell count was expressed as the number of positive Bcl-2 cells per mm(2). No significant difference in the number of cells marked by the Bcl-2 protein was found for the variables age, tumor diameter, angiolymphatic invasion or number of lymph nodes affected. Comparison of the number of cells marked by the Bcl-2 protein in the two histological groups revealed a statistically significant difference, with squamous tumors presenting a greater number of marked cells. Squamous cervical tumors present a greater number of positive Bcl-2 cells per mm(2), suggesting that that the rate of cell death in squamous cell carcinomas of the cervix is lower than in adenocarcinomas.

    To develop a modified technique for high-dose-rate intracavitary brachytherapy in cervical cancer stage IIIb. Cervical carcinoma FIGO Stage III accounts for > 60% of all cervical cancers with radiation being the mainstay of treatment for most patients. After external beam radiation therapy (EBRT), the cervix is often flush with the vagina and the shape of the vagina may be conical with its apex at the external os level. All patients receive 2 applications with HDR brachytherapy. At the first application after the placement of the central tandem, only one ovoid is inserted and the other ovoid is replaced by a rubber tube, and the applicator assembly is fixed as usual. The contralateral ovoid is inserted at the subsequent application. To date, 21 locally advanced cervical cancer patients have been treated using this technique. In these patients, the mean dose to right and left Point A was 93% (range, 86-100%; median, 93%) and 95% (range, 90-100%; median, 95%), respectively. The variation of doses to the contralateral Point A was 1-14%. The mean dose to the rectal and bladder mucosa was 62% (range, 43-80%; median, 64%) and 80% (range, 50-110%; median, 71%), respectively. This modified HDR intracavitary technique may prove an alternative for centers where interstitial brachytherapy for cancer of the cervix is not available.

    Twenty patients with invasive carcinoma of the cervix (FIGO stages IB-IV) were staged by routine pelvic examination, intravenous urography, chemistry studies, and barium enema. All patients received a CT scan of the abdomen and pelvis followed by pelvic examination under anesthesia (EUA). CT agreed with EUA staging in 13 of 20 patients (65%). All patients had surgical para-aortic lymph node sampling. The sensitivity of CT for para-aortic lymph node involvement was 67% and the specificity was 92%. CT scanning is equal to other clinical staging procedures for carcinoma of the cervix. It offers the avantages of being noninvasive and visualizing tumor for the construction of radiation portals. CT is useful in the detection of para-aoric lymphadenopathy; however, the presence of normal sized or enlarged nodes makes pathologic examination, either by needle aspiration or surgery, necessary.

    High dose therapeutic irradiation for carcinoma of the cervix, usually delivered using a combination of external and intracavitary sources, may damage the rectum, sigmoid, distal small bowel, vagina, and urinary bladder. A pretreatment barium enema is valuable for baseline comparison should symptoms developing after treatment necessitate radiographic evaluation of the colon and rectum. Included in this review are a summary of radiation therapy techniques for carcinoma of the cervix, the radiation tolerance of normal pelvic structures, and the histopathology of changes in the bowel following irradiation. The spectrum of radiographic manifestations of radiation effect on the rectum and sigmoid is presented and contrasted with changes secondary to recurrent of persistent tumor. Gradations of symmetrical volume loss characterize radiation change, whereas mass effect, asymmetrical narrowing of the colon lumen, or fixation are more typical of tumor recurrence.

    All cases of uterine perforation occurring during intracavitary application for carcinoma of the cervix over a 13-year period (1968-1981) were reviewed. There were 14 perforations out of 799 applications in 622 patients, for an incidence of 2.25% of patients and 1.75% of applications. In most cases, it is sufficient to halt the application and carefully monitor the patient, as supported by the uneventful post-perforation course in 12 cases. Nine patients (64%) underwent subsequent intracavitary application without further complications; of these, 8 are still living or died without evidence of tumor. In the other 5, it was impossible to locate the cervical canal on subsequent applications. Alternative treatments, results of therapy, and analysis of failures are presented. The authors conclude that there is no direct evidence that uterine perforation alters the prognosis following radiation therapy for carcinoma of the cervix.

    Adenoid basal carcinoma (ABC) is an uncommon neoplasm of the uterine cervix. ABC can be accompanied by carcinoma in situ or invasive carcinoma. Most cases are discovered accidentally during radical hysterectomy. ABC is associated with a high risk of human papillomavirus infection (HPV), most often HPV 16 infection. We present a rare case of an 86-year-old Taiwanese married woman who suffered from bloody vaginal discharge and occasional lower abdominal pain and received cervical biopsy. The pathological report revealed squamous cell carcinoma (SCC) of the uterine cervix. After radical hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic and para-aortic lymph node dissection, the final pathological report revealed SCC coexisting with ABC, and both of the components were infected by HPV 31. After receiving radiotherapy, she maintained outpatient department follow-up. A literature review revealed that this was a rare case of combined ABC-SCC associated with HPV 31 infection. In this case, the ABC component did not affect the tumor stage because it was confined to the cervix. However, we must avoid overestimating the clinical stage because the ABC component is thought to be a benign lesion. Copyright © 2013. Published by Elsevier B.V.

    A relationship between hypoxia and apoptosis has been identified in vitro and in experimental tumours. The aim of this study was to investigate the relationship between apoptosis, hypoxia and the change in oxygenation during radiotherapy in human squamous cell carcinoma of the cervix. Forty-two patients with locally advanced disease underwent pretreatment evaluation of tumour oxygenation using an Eppendorf computerized microneedle electrode. Twenty-two of these patients also had a second evaluation of tumour oxygenation after receiving 40–45 Gy external beam radiotherapy. Paraffin-embedded histological sections were obtained from random pretreatment biopsies for all 42 patients. Apoptotic index (AI) was quantified by morphology on TUNEL stained sections. No correlation was found between pretreatment measures of AI and either the median pO2(r = 0.12, P = 0.44) or percentage of values < 5 mmHg (r = –0.02, P = 0.89). A significant positive correlation was found between AI and the change in tumour oxygenation (ratio of pre:post-treatment % values < 5 mmHg) following radiotherapy (r = 0.61, P = 0.002). The lack of correlation between apoptosis and hypoxia may occur because the Eppendorf measures both acute and chronic hypoxia, and the relative ability of acute hypoxia to induce apoptosis is unknown. These results indicate that cell death via apoptosis may be a mechanism of tumour reoxygenation during radiotherapy. © 2000 Cancer Research Campaign PMID:10735502

Ten years previously the patient had been treated for squamous cell carcinoma of the cervix. Although lymphangioma circumscriptum is an extremely rare complication of altered lymphatic drainage, the presence of multiple noninflammatory vesicular appearing lesions in this setting should suggest the correct diagnosis.

    Radiation changes are observed in all postirradiated smears of squamous cell carcinoma of the cervix from 56 females, although to a variable degree. After 1 year the changes subside gradually. A high cornification index is a good guide for recurrence. The significance of dysplastic cells as premonition for recurrence is debatable. The presence of malignant cells at any stage was considered of grave significance, and indicates poor radiation response or recurrence.

    Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

    Purpose: To report the long-term outcome after radiotherapy with curative intent for Stage IIIB and IVA carcinoma of the cervix. Methods and Materials: We retrospectively reviewed 91 patients treated with radiotherapy with curative intent at University of Florida between January 1980 and December 2003 for Stage IIIB (84 patients) or IVA (7 patients) carcinoma of the cervix. Results: The median follow-up of the surviving patients was 8.8 years. The 5- and 10-year estimates of local control, regional control, locoregional control, relapse-free survival, and overall survival were 53% and 53%, 55% and 47%, 34% and 29%, 30% and 26%, and 29% and 21%, respectively. Ninety percent of the recurrences occurred within 2 years of treatment. Of these, 60% of all failures were local, 29% were regional, and 11% were distant failures alone. Also, 17% of the failures were in the paraaortic nodes with no evidence of failure in the pelvis. Univariate and multivariate analyses were conducted with the endpoint of relapse-free or overall survival. No factor was statistically significant. Complications from therapy were scored using the Radiation Therapy Oncology Group grading system; the overall severe late complication rate was 13% (Grade 3-5). Conclusion: This series is one of the most mature of published reports. With long-term follow-up, approximately one-third of patients with Stage IIIB or IVA carcinoma of the cervix were cured, with a 13% complication rate.

    In order to explain why modes of sexual life influence the incidence of cervical carcinoma, several factors have been claimed to be involved. There is no solid basis for the hypothesis that sperm may be mutagenic. By contrast, epidemiological studies showed that partners whose life is not sedentary bring back home to their wives an increased risk of cervical carcinoma. The infectious factor does not seem to be associated with syphilis but may well be represented by herpes genitalis virus (Herpes Simplex type 2 virus). Women with cervical carcinoma show a variety of immunes reactions to this virus, and these reactions are statistically less frequent in control groups. In the laboratory, mouse and hamster cells have been transformed into cancerous cells by means of herpes simplex virus type 2.

    The survival of cervical carcinoma patients with paraaortic/high common iliac nodal metastases was evaluated by retrospective chart review during a 13-year interval. Thirty-three patients with cervical carcinoma and surgically documented nodal metastases received primary, extended-field radiation therapy. Overall 2-year and 5-year actuarial survival rates after diagnosis were 37% and 31%, respectively. Survival was analyzed in terms of the variables patient age, clinical stage, tumor histologic type, the presence of enlarged paraaortic/high common iliac lymph nodes, the extent of nodal involvement (microscopic versus macroscopic), the presence of intraperitoneal disease, and whether intracavitary brachytherapy was administered. The use of intracavitary radiation therapy was associated with improved local control and survival (P = 0.017). None of the other variables were statistically related to patient survival. Twenty-two of the patients died of cervical cancer and five are surviving without evidence of cancer. Four patients died of intercurrent disease. Two patients developed bowel-related radiation complications; both patients received chemotherapy concurrent with the radiation therapy. One of the two patients died of radiation enteritis. The use of extended-field radiation therapy does benefit a small group of patients and may result in extended patient survival.

    Cervix carcinoma is an important health problem world-wide, being the second most common cancer among women, ranking first in many developing countries. A number of important epidemiological risk factors have been identified as contributing to the development of CIN and invasive cervix carcinoma. Of key importance is infection with human papillomavirus (HPV), which is the primary risk factor. There are evolving primary and secondary preventive strategies that could further reduce the burden from cervical carcinoma. The possible primary preventive strategies include risk reduction, diet or dietary supplements, HPV vaccines, and other chemopreventive agents. The possible advances in secondary preventive strategies include new technologies for Pap smears, HPV typing triage, and other adjuvant screening procedures. The impact of these strategies will depend upon evidence to support their use along with the characteristics of the population and environment in which they are used.

    Ureteral stricture is a rare late complication of curative radiotherapy for carcinoma of the cervix. A retrospective study was performed to determine the incidence and latency of radiation-induced ureteral stricture, to investigate possible contributing factors, and to compare the time course and presenting characteristics of ureteral compromise caused by late radiation injury or tumor recurrence. The records of 1784 patients with FIGO stage IB carcinoma of the cervix treated with radiotherapy at The University of Texas M. D. Anderson Cancer Center between 1960 and 1989 were reviewed. The characteristics of patients who developed ureteral stricture as a first manifestation of recurrent disease or without evidence of pelvic recurrence were compared. The risk of ureteral compromise was calculated actuarially. There were 29 patients with severe radiation-induced ureteral stricture. The overall incidences of severe ureteral stenosis were 1.0, 1.2, 2.2, and 2.5% at 5, 10, 15, and 20 years, respectively, reflecting a continuous actuarial risk increase of approximately 0.15% per year. Four patients died of complications from bilateral ureteral stricture. Patients who were treated with centrally blocked external fields or who received more than two transvaginal radiation treatments were at increased risk for developing ureteral stenosis. The risk was similar for patients treated with radiation alone or followed by extrafascial hysterectomy. During the first 5 years after treatment, tumor recurrence is the most common cause of ureteral stricture in patients treated with radiotherapy for carcinoma of the cervix. However, radiation injury to the ureter, although rare, may not become apparent for many years, necessitating continued vigilance throughout the lives of these patients.

    Purpose: The purpose of this study was to analyze tumor heterogeneity based on tumor extent and suggest reappraisal of the system of the International Federation of Gynecology and Obstetrics (FIGO) for Stage III carcinoma of the uterine cervix from a radiotherapeutic viewpoint. Methods and Materials: Between 1986 and 2004, 407 patients with FIGO Stage III (FIGO Stage IIIa in 19 and IIIb in 388) were treated with external beam radiotherapy (RT) and high-dose rate brachytherapy. All patients were reviewed with respect to tumor extent. Patterns of failure and survival parameters were analyzed by use of the chi{sup 2} test and Kaplan-Meier method. Results: The complete response rate was 79.6%, and the 5-year overall survival rates for Stage IIIa and Stage IIIb carcinoma of the cervix were 82.1% and 54.8%, respectively. To determine which parameters of tumor extent had an influence on prognosis for Stage IIIb patients, pelvic wall (PW) extension and hydronephrosis (HD) retained significance on multivariate analysis. Stage IIIb patients were divided into three subgroups according to PW extension and HD: low risk (unilateral PW extension without HD), intermediate risk (HD without PW extension or bilateral PW extension without HD), and high risk (unilateral or bilateral PW extension with HD). The high-risk group had a remarkably low complete response rate, high locoregional failure rate, and low 5-year survival rate compared with the intermediate- and low-risk groups. Conclusions: FIGO Stage III carcinoma of the cervix covers considerably heterogeneous subgroups according to tumor extent. Before initiation of treatment, we suggest that physicians determine a tailored treatment policy based on tumor heterogeneity for each Stage III patient.

    -effectiveness ratio (ICER) of topotecan plus cisplatin versus cisplatin monotherapy was 17,974 pounds per QALY in the main licensed population, 10,928 pounds per QALY in the cisplatin-naive population (including stage IVB patients) and 32,463 pounds per QALY in sustained cisplatin-free interval patients. In response to the point for clarification raised by the ERG, the manufacturer submitted a revised indirect comparison incorporating HRQoL and a longer time horizon. Where the hazard ratio derived from GOG-0169 was employed, paclitaxel plus cisplatin was dominated by topotecan plus cisplatin, but, where the hazard ratio from GOG-0204 was adopted, paclitaxel plus cisplatin was found to have an ICER of 13,260 pounds per QALY versus topotecan plus cisplatin. At present there is a paucity of evidence available on the clinical effects of topotecan plus cisplatin and the effects of palliative treatment in general for women with advanced and recurrent carcinoma of the cervix. Further trials, or the implementation of registries, are required to establish the efficacy and safety of topotecan plus cisplatin. The guidance issued by NICE on 28 October 2009 as a result of the STA states that topotecan in combination with cisplatin is recommended as a treatment option for women with recurrent or stage IVB cervical cancer, only if they have not previously received cisplatin. Women who have previously received cisplatin and are currently being treated with topotecan in combination with cisplatin for the treatment of cervical cancer should have the option to continue therapy until they and their clinicians consider it appropriate to stop.

    FOXA1 is a major transcription factor involved in the action of human papilloma virus (HPV). However, it has been never studied in HPV-associated tumors. To investigate its expression in cervical and head and neck tumors. 63 cervical carcinomas/dysplasias and 152 head and neck squamous cell carcinomas (HNSCC) were immunohistochemically studied for the expression of FOXA1. 63.1% of cervical SCC and 40.7% of endocervical adenocarcinomas strongly expressed FOXA1. Most (90%) pre-invasive lesions (CIN3 and in situ adenocarcinomas) strongly expressed FOXA1 and this difference from invasive lesions was statistically significant (p=0.005). No association with clinicopathological factors was found. 51.3% of HNSCC expressed FOXA1. In these tumors, FOXA1 expression was associated with the non-keratinizing morphology but not with the HPV/p16 status neither other clinicopathological features. Of normal structures, salivary glands, endocervical glands and basal/parabasal cell layer of squamous epithelium of both uterine cervix and head and neck mucosa, all strongly expressed FOXA1. FOXA1 is expressed by basal cells of squamous epithelium, pre-invasion lesions of the uterine cervix and the head/neck and almost half invasive cervical and head/neck carcinomas, supporting its possible implication in HPV pathogenesis.

    To evaluate the prevalence of high-risk type human papillomavirus (HR-HPV) in preneoplastic lesions and invasive squamous cell carcinoma (SCC) of the cervix uteri in southern Thai women. A total of 148 formalin-fixed, paraffin-embedded blocks of cervix tissue were retrieved from the files of the Department of Pathology, Prince of Songkla University Hospital. They were classified as negative for intraepithelial lesion (NIL) in 37 cases, low grade lesion (LGL) in 58 cases, high grade lesion (HGL) in 39 cases and SCC in 14 cases. HR-HPV DNA was tested with an Amplicor HPV (Roche Diagnostics) detection kit. Of the 111 cases, 42 of 58 LGLs (72.4%), 34 of 39 HGLs (87.2%) and 13 of 14 SCCs (92.9%) were positive for HR-HPV DNA. In 37 cases of histologically normal cervix, there were 15 cases that showed the presence of HR-HPV DNA. Applying the HR-HPV results for NILs to the general population, the age standardized incidence rate of HR-HPV infection in the normal Thai population was 12.8%. HR-HPV DNA can be found in all grades of intraepithelial lesions and carcinoma of the cervix uteri, even in the histologically "normal" looking cervix. These results provide strong evidence for a role in carcinogenesis of the cervix uteri and the existence of a non-productive or latent period of HPV infection.

    To evaluate perioperative and postoperative complications of low-dose-rate (LDR) intracavitary radiation therapy in patients with FIGO Stage I-III carcinoma of the uterine cervix. We retrospectively reviewed the medical and radiotherapy records of all patients treated with radiation between 1960 and 1992 at The University of Texas M. D. Anderson Cancer Center for FIGO I-III carcinomas of the cervix. Patients who had had initial hysterectomy or whose treatment did not include intracavitary irradiation were excluded. The final study included 4043 patients who had undergone 7662 intracavitary procedures. Eleven (0. 3%) patients had documented or suspected cases of thromboembolism resulting in 4 deaths. Of these 11 patients, 8 had clinical or radiographic evidence of tumor involving pelvic nodes or fixed pelvic wall. The risk of postoperative thromboembolism did not decrease significantly with the routine use of mini-dose heparin prophylaxis (p = 0.3). Other life-threatening perioperative complications included myocardial infarction (1 death in 5 patients), cerebrovascular accident (2 patients), congestive heart failure or atrial fibrillation (3 patients), and halothane liver toxicity (2 deaths in 2 patients). Intraoperative complications included uterine perforation (2.8%) and vaginal laceration (0.3%), which occurred more frequently in patients >/= 60 years old (p < 0.01). Fourteen percent of patients had a temperature >/= 101 degrees F during at least one hospital stay. The only correlation between minor intraoperative complications and disease-specific survival was found in patients who had Stage III disease and uterine perforation; survival was significantly (p = 0.01) decreased in these patients. Fatal or life-threatening complications of intracavitary treatment were very rare. Deep venous thrombosis (DVT) and pulmonary embolism (PE) did not occur in otherwise healthy patients with early disease and were rare even when disease was more advanced. Minor

    From 1964 to 1980, 97 patients with Stage IIb carcinoma of cervix uteri were treated by external 60Co irradiation alone. Of these 97 patients, 94 (96.9%) had squamous cell carcinoma. The parametrial extension of the lesion almost reached the pelvic wall in 73.2% and vaginal extension reached to the upper half of vaginal in 24.7% of the patients. A tumor dose of 60 Gy was given to the whole pelvis by a four field technic (opposing parallel AP and lateral portals) in 6-8 weeks. A booster dose of 10 Gy was delivered to the cervix by a pair of reduced opposing parallel AP portals or a perineal portal in a week. The doses delivered were equivalent to the Time-Dose-Fractionation (TDF) value of 110-130 at the center of pelvis and 90-110 in the whole pelvis. The 5-year survival rate for all 97 patients was 56.7%. It was 59.8% when those who died of other diseases were excluded. The prognosis of patients without residual tumor on the cervix and/or vagina was better than that with residual tumor (p less than 0.01). Thirty-seven patients died of cancer (23 died of recurrence, 8 of distant metastases, 2 of both, and 4 were lost before the fifth year). Of these 37 patients, 97.3% died within 3 years after initial treatment. During the radiation treatment, reactions were moderate. Late complications included 19 (19.6%) with mild cystitis and 16 (16.5%) with mild proctitis, 2 (2.7%) developed recto-vaginal fistula. These results were slightly poorer than those using intracavitary and external irradiation or the combination of preoperative irradiation plus surgery. Yet, for patients with extensions nearing the pelvic wall or with contra-indications to surgery or intracavitary radiotherapy, external irradiation alone is still of value.

    To determine MR imaging features and staging accuracy of neuroendocrine carcinomas (NECs) of the uterine cervix with pathological correlations. Twenty-six patients with histologically proven NECs, 60 patients with squamous cell carcinomas (SCCs), and 30 patients with adenocarcinomas of the uterine cervix were included. The clinical data, pathological findings, and MRI findings were reviewed retrospectively. MRI features of cervical NECs, SCCs, and adenocarcinomas were compared, and MRI staging of cervical NECs was compared with the pathological staging. Cervical NECs showed a higher tendency toward a homogeneous signal intensity on T2-weighted imaging and a homogeneous enhancement pattern, as well as a lower ADC value of tumour and a higher incidence of lymphadenopathy, compared with SCCs and adenocarcinomas (P < 0.05). An ADC value cutoff of 0.90 × 10(-3) mm(2)/s was robust for differentiation between cervical NECs and other cervical cancers, with a sensitivity of 63.3 % and a specificity of 95 %. In 21 patients who underwent radical hysterectomy and lymphadenectomy, the overall accuracy of tumour staging by MR imaging was 85.7 % with reference to pathology staging. Homogeneous lesion texture and low ADC value are likely suggestive features of cervical NECs and MR imaging is reliable for the staging of cervical NECs. • Cervical NECs show a tendency of lesion homogeneity and lymphadenopathy • Low ADC values are found in cervical NECs • MRI is an accurate imaging modality for the cervical NEC staging.

    The breast is an extremely rare target organ for metastasis of extramammary neoplasms. The occurence varies between 1.7% to 6.6% in autopsies; between 1.2% and 2% in clinical cases; and around 2.7% in sputum series. In accordance with the primary tumor localization, it is more common to find metastases of lymphoma, melanoma, rhabdomyosarcoma, tumors of the lung and ovarian tumors. Breast metastasis of the uterine cervix is a very seldomly found. According to the published literature so far there have been around 30 documented cases with such pathology. This study presents the case of a 48-year-old female with a squamous cell carcinoma of the uterine cervix, which was histologically verified in 2010. Three years after the initial tumor diagnosis, radiotherapy and chemotherapy, the patient was found to have a cystic tumor formation in one of her breasts. The formation was painful to pressure. Quadrantectomy with an open bisopsy was performed to the patient. Histological and immunohistochemical diagnosis rejected primary squamous cell carcinoma of the breast. The differential diagnosis of metastatic lesions in the breast is problematic and requires careful clinical history, immunohistochemical study and multidisciplinary approach in the management. Mammary metastases are a bad predictor and they serve as an indicator of generalized dissemination of the primary tumor process.

    To explore the differentially expressed proteins in normal cervix, cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) tissues by differential proteomics technique. Cervical tissues (including normal cervix, CIN and CSCC) were collected in Department of Gynecologic Oncology of Beijing Obstetrics and Gynecology Hospital. Two-dimensional fluorescence difference in gel electrophoresis (2-D DIGE) and DeCyder software were used to detect the differentially expressed proteins. Matrix-assisted laser desorption/ionization-time-of-flight tandem mass spectrometry (MALDI-TOF/TOF MS) was used to identify the differentially expressed proteins. Western blot (WB) and immunohistochemistry (IHC) were performed to validate the expressions of selected proteins among normal cervix, CIN and CSCC. 2-D DIGE images with high resolution and good repeatability were obtained. Forty-six differentially expressed proteins (27 up-regulated and 19 down-regulated) were differentially expressed among the normal cervix, CIN and CSCC. 26 proteins were successfully identified by MALDI-TOF/TOF MS. S100A9 (S100 calcium-binding protein A9) was the most significantly up-regulated protein. Eukaryotic elongation factor 1-alpha-1 (eEF1A1) was the most significantly down-regulated protein. Pyruvate kinase isozymes M2 (PKM2) was both up-regulated and down-regulated. The results of WB showed that with the increase in the severity of cervical lesions, the expression of S100A9 protein was significantly increased among the three groups (P = 0.010). The expression of eEF1A1 was reduced but without significant difference (P = 0.861). The expression of PKM2 was significantly reduced (P = 0.000). IHC showed that protein S100A9 was mainly expressed in the cytoplasm, and its positive expression rate was 20.0 % in normal cervix, 70.0 % in CIN and 100.0 % in CSCC, with a significant difference among them (P = 0.006). eEF1A1 was mainly expressed in the cell plasma, and its

It is known that this gland is situated at the site of the original junction between the cylindrical and pavement epithelia. It confirms that carcinoma-in-situ always (with few exceptions) develops upwards from the area of the original junction between the cylindrical and pavement epithelia, and its topography is higher than that of dysplasia especially when the two types of lesion are associated.

    Background: There is a need for simple imaging parameters capable of predicting therapeutic outcome. Methods: This retrospective study analysed 50 patients with locally advanced carcinoma of the cervix who underwent dynamic contrast-enhanced MRI before receiving potentially curative radiotherapy. The proportion of enhancing pixels (EF) in the whole-tumour volume post-contrast agent injection was calculated and assessed in relation to disease-free survival (DFS). Results: Tumours with high EF had a significantly poorer probability of DFS than those with low EF (P=0.011). Interpretation: EF is a simple imaging biomarker that should be studied further in a multi-centre setting. PMID:19920831

    Lymphoepithelioma-like carcinoma (LELC) is a rare neoplasm of the cervix. The importance of distinguishing this undifferentiated carcinoma with a predominant lymphocytic infiltrate lies in the fact that despite being poorly differentiated they have a better prognosis. The diagnosis however becomes more challenging when the pathologist is provided with a small cervical biopsy or a Papanicolaou smear. While the reports describing histology and their relation to Epstein-Barr virus (EBV) are many, there are only few case reports describing the cytology of these tumors. We describe the cytological features of LELC of cervix on conventional smear and correlate it with the histopathological findings of the same. A 67-year-old multiparous Hindu woman presented to the gynecology outpatient department with the history of postmenopausal bleeding for the past six months. The cytological examination of the cervical smear (Papanicolaou stain) was done followed by cervical and endometrial biopsy. Based on Papanicolaou smear and biopsy suggestive of a poorly differentiated carcinoma a radical hysterectomy with pelvic lymphadenectomy was performed. Hysterectomy specimen showed the morphology of LELC and was then correlated with the cervical smears retrospectively. On review of cytological smears it was seen that the tumor cell clusters had an abundant lymphoid background, which was overlooked earlier. Immunohistochemistry for EBV was negative. We conclude that the presence of undifferentiated tumor cell clusters with ill-defined cell borders and large number of lymphoid cells in the background suggest the diagnosis of LELC on cervical cytology.

    Cf-252 is an isotope that can easily be after loaded into available gynecological applicators and used for bulky cervix, uterus or vaginal cancer therapy. It is economical, time and cost effective in use, and can be applied to the therapy of many patients throughout the world. It is more effective for neutron therapy than machine fast neutron therapy and is the only form of neutron therapy producing consistent complication-free 5-year cure of advanced cancers currently available. Cf-252 is an isotope for modern gynecological tumor therapy for the future. Isodose curves for Cf-252 implants revealed dose distributions conforming well to tumor.

    One hundred and two patients with invasive carcinoma of the uterine cervix, stages IB, IIA, and selected IA and IIB, were treated using combined radiation therapy and radical hysterectomy. Of these, 88 received approximately 2000 rad of pelvic external radiation and a single 5000-6000 mgh intracavitary implant. Major complications were observed in 5 patients. These resolved spontaneously in 1, and were surgically managed in satisfactory manner in the other 4. Only two of the complications occurred in patients receiving low dose preoperative irradiation. The likelihood of complications was closely related to the radiation dosage. Preoperative radiation prior to radical hysterectomy can be given safely provided that dosimetric principles are observed, and that the radiation and surgical techniques are integrated closely.

    Cisplatin and paclitaxel both can cause peripheral neurotoxicity as an adverse effect; however, central nervous system neurotoxicity in the form of seizures is rare. We report a case of a 36-year-old female patient of metastatic carcinoma cervix, who developed seizure shortly after cisplatin infusion. Her laboratory investigations were within normal limits. Computed tomography scan and magnetic resonance imaging of the brain did not reveal brain primary metastasis or meningeal carcinomatosis. She had no complaints of fever, no signs and symptoms of infection, and no history of seizure nor was she on any medication predisposing to such an event. Excluding several causes, seizure was thought to be most likely related to the chemotherapy and cisplatin was the more likely agent in view of observed temporal relationship with the adverse event.

    Purpose: To evaluate the utility of sequential {sup 18}F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging for brachytherapy treatment planning in patients with carcinoma of the cervix. Methods and Materials: Twenty-four patients with carcinoma of the cervix were included in this prospective study. The clinical stage of their disease was Ib (7), IIa (1), IIb (7), and IIIb (9). Patients were treated with irradiation and brachytherapy, with the majority receiving concurrent weekly cisplatin chemotherapy. Patients underwent diagnostic FDG-PET imaging before treatment, sequential FDG-PET brachytherapy imaging during treatment, and diagnostic FDG-PET 3 months after treatment completion. Delineation of the gross tumor volume, bladder, and rectum was performed for all scans using a commercially available treatment-planning system. Actual treatment delivery was based on two-dimensional orthogonal planning. Results: The mean gross tumor volume and percent coverage by the target isodose surface for the initial, mid, and last implant were 37 cm{sup 3}, 17 cm{sup 3}, and 10 cm{sup 3} and 68%, 76%, and 79%, respectively. Nine of 11 patients were found to have continued decrease in tumor volume as measured by FDG-PET, with 3 patients having complete regression of their tumor before treatment was completed. The maximal bladder and rectal doses obtained from three-dimensional dose-volume histograms were significantly higher than the International Commission on Radiation Units and Measurements Report 38 bladder and rectal points obtained by two-dimensional treatment-planning. Conclusions: Sequential FDG-PET brachytherapy imaging identifies the tumor response in individual patients, potentially making patient-specific brachytherapy treatment planning possible.

    Background Uterine cervix carcinoma is the second most common female malignancy worldwide and a major health problem in Mexico, representing the primary cause of death among the Mexican female population. High risk human papillomavirus (HPV) infection is considered to be the most important risk factor for the development of this tumor and cervical carcinoma derived cell lines are very useful models for the study of viral carcinogenesis. Comparative Genomic Hybridization (CGH) experiments have detected a specific pattern of chromosomal imbalances during cervical cancer progression, indicating chromosomal regions that might contain genes that are important for cervical transformation. Methods We performed HPV detection and CGH analysis in order to initiate the genomic characterization of four recently established cervical carcinoma derived cell lines from Mexican patients. Results All the cell lines were HPV18 positive. The most prevalent imbalances in the cell lines were gains in chromosomes 1q23-q32, 3q11.2-q13.1, 3q22-q26.1, 5p15.1-p11.2, this alteration present as a high copy number amplification in three of the cell lines, 7p15-p13, 7q21, 7q31, 11q21, and 12q12, and losses in 2q35-qter, 4p16, 6q26-qter, 9q34 and 19q13.2-qter. Conclusions Analysis of our present findings and previously reported data suggest that gains at 1q31-q32 and 7p13-p14, as well as losses at 6q26-q27 are alterations that might be unique for HPV18 positive cases. These chromosomal regions, as well as regions with high copy number amplifications, coincide with known fragile sites and known HPV integration sites. The general pattern of chromosomal imbalances detected in the cells resembled that found in invasive cervical tumors, suggesting that the cells represent good models for the study of cervical carcinoma.

    Although cervical carcinoma is among the most frequently encountered malignancies during pregnancy only a small number of cases during pregnancy have been reported. Usually, the patients have been treated by radical trachelectomy with or without chemotherapy during the pregnancy. Laparoscopic pelvic lymph node dissection with frozen section, simple trachelectomy and cerclage were performed in the 22(nd) week of pregnancy. The histologic examination confirmed a squamous cell carcinoma of the cervix of 35mm diameter, lymphangioinvasion (L1), low grade, clear surgical margin, negative pelvic lymph nodes according to stage Figo IB. Adjuvant chemotherapy with three cycles of cisplatin was performed after surgery. Delivery was performed by cesarean section followed by radical hysterectomy in the the 32(nd) week of pregnancy. Recurrent adjuvant chemotherapy with three cycles of cisplatin and local vaginal iridium radiation were performed after surgery. Patient had no surgery related complications. No relapse of cancer has been diagnosed during the following 16 months. Simple trachelectomy may be alternative treatment option to radical trachelectomy for pregnant women with early stage cervical cancer without lymph node metastasis.

    Pimonidazole binding (hypoxia) and involucrin expression (differentiation) overlap extensively in squamous cell carcinomas. This study asks whether involucrin might serve as an endogenous marker for tumor hypoxia. A second question is whether differentiation affects hypoxia-inducible metallothionein (MT) expression in normal human epithelia and squamous cell carcinomas as it does in rodent epithelia. Thirty-four patients with squamous cell carcinoma of the uterine cervix were infused with pimonidazole hydrochloride solution. The next day, multiple biopsies were formalin-fixed, paraffin-embedded and sectioned at 4 micro m. Qualitative and quantitative analyses for involucrin expression, pimonidazole binding, and human MT-IIa mRNA expression were performed. No overall correlation between the extent of involucrin expression and pimonidazole binding was observed. The lack of correlation was because of heterogeneous patterns of immunostaining for involucrin generally related to tumor grade. Colocalized immunostaining for involucrin and pimonidazole binding was observed in intermediate grade tumors but not in well-differentiated or poorly differentiated tumors. Human MT-IIa mRNA and MT protein were expressed in basal lamina of normal human epithelia and in the proliferative rims of tumor nests. Colocalization of immunostaining for involucrin and pimonidazole binding is consistent with oxygen regulation, but the lack of involucrin expression in hypoxic regions of poorly differentiated tumors indicates that its transcriptional status with respect to hypoxia induction is altered by cell differentiation. The localization of MT message and protein in the outer rims of most tumor nests indicates that the transcriptional status of metallothionein is also altered by differentiation.

    A retrospective analysis was performed to describe the cytomorphological and histopathological findings and human papillomavirus (HPV) genotypes for glassy cell carcinoma (GCC) of the uterine cervix. Five cases of cervical GCC, in which the glassy cell features constituted at least 95% of the specimen, were included. Four patients had stage IIB GCCs and one had stage IIIB GCC. All patients underwent concurrent chemoradiation therapy. Based on pretreatment cytology, only 1 of the 5 cases was correctly diagnosed as GCC. The remaining cases were diagnosed as carcinoma of undetermined type, adenocarcinoma, poorly differentiated carcinoma, or unsatisfactory for evaluation. Cytological specimens had moderate cellularity and contained small clusters of tumor cells admixed with amphophilic, granular tumor diathesis. The tumor cells possessed large, round to oval nuclei and abundant, granular, ground-glass cytoplasm. The nuclei exhibited prominent eosinophilic nucleoli. The cytoplasm displayed sharp margins and molding, resulting in “intercellular windows” between neighboring attached cells. HPV genotyping revealed that high-risk HPV types 18, 16, and 31 were detected in 3, 1, and 1 cases, respectively. Consistent with this finding, all cases exhibited block p16 positivity, confirming the association of HPV infection with GCC. In conclusion, a distinct cytoplasmic margin, the characteristic histopathological feature of GCC, was observed in liquid-based cytological preparations. We suggest that sharp cytoplasmic outlines with molding and intercellular windows are characteristic cytomorphological features of GCC. Detection of high-risk HPV in all cases strongly supported the notion that high-risk HPV is involved in the pathogenesis of GCC. PMID:27708230

    In this study, squamous cell carcinoma antigen (SCC) was detected in 96 of 157 patients with squamous cell carcinoma of the cervix and the percentage of patients with raised SCC levels increased with the stage of disease (P less than 0.01). The use of serial SCC assays and cervical biopsy histology during the course of radiotherapy to predict tumor response to irradiation was assessed. In patients who were given external irradiation before intracavitary radium, a high SCC level or the presence of viable tumor cells in the biopsy was found to be of no predictive value. However, at completion of radiotherapy, i.e., after intracavitary radium application, patients with persistently high SCC levels had a significantly higher incidence of residual tumor than patients whose SCC levels returned to normal (P less than 0.01). In 60% of patients with a persistently high SCC level, viable tumor was found in the cervical biopsy at the end of radiotherapy. On the other hand, only 5.4% of patients whose SCC level returned to normal had residual tumor.

    While the incidence of squamous carcinoma of the cervix has declined in countries with organised screening, adenocarcinoma has become more common. Cervical screening by cytology often fails to prevent adenocarcinoma. Using prospectively recorded cervical screening data in England and Wales, we conducted a population-based case-control study to examine whether cervical screening leads to early diagnosis and down-staging of adenocarcinoma. Conditional logistic regression modelling was carried out to provide odds ratios (ORs) and 95% confidence intervals (CIs) on 12,418 women with cervical cancer diagnosed between ages 30 and 69 and 24,453 age-matched controls. Of women with adenocarcinoma of the cervix, 44.3% were up to date with screening and 14.6% were non-attenders. The overall OR comparing women up to date with screening with non-attenders was 0.46 (95% CI: 0.39-0.55) for adenocarcinoma. The odds were significantly decreased (OR: 0.22, 95% CI: 0.15-0.33) in up to date women with Stage 2 or worse adenocarcinoma, but not for women with Stage1A adenocarcinoma 0.71 (95% CI: 0.46-1.09). The odds of Stage 1A adenocarcinoma was double among lapsed attenders (OR: 2.35, 95% CI: 1.52-3.62) compared to non-attenders. Relative to women with no negative cytology within 7 years of diagnosis, women with Stage1A adenocarcinoma were very unlikely to be detected within 3 years of a negative cytology test (OR: 0.08, 95% CI: 0.05-0.13); however, the odds doubled 3-5 years after a negative test (OR: 2.30, 95% CI: 1.67-3.18). ORs associated with up to date screening were smaller for squamous and adenosquamous cervical carcinoma. Although cytology screening is inefficient at preventing adenocarcinomas, invasive adenocarcinomas are detected earlier than they would be in the absence of screening, substantially preventing Stage 2 and worse adenocarcinomas. © 2016 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    Purpose: To evaluate the pretreatment risk factors of para-aortic lymph node (PALN) recurrence after primary radiotherapy for cervical cancer. Methods and Materials: Between May 1992 and January 2006, the data from 758 patients with squamous cell carcinoma of the uterine cervix were retrospectively analyzed. No patient had undergone PALN radiotherapy as their initial treatment. PALN recurrence was diagnosed by computed tomography. PALN relapse-free status was determined clinically or radiographically. We analyzed the actuarial rates of PALN recurrence using Kaplan-Meier curves. Multivariate analyses were performed with Cox regression models. Results: Of the 758 patients, 38 (5%) and 42 (6%) had isolated and nonisolated PALN recurrences after a median follow-up of 50 months (range, 2-159 months), respectively. The 3-year and 5-year overall survival rate after PALN recurrence was 35% and 28%, respectively. A squamous cell carcinoma antigen (SCC-Ag) level >40 ng/mL (p <0.001), advanced parametrial involvement (score 4-6; p = 0.002), and the presence of pelvic lymphadenopathy (p = 0.007) were independent factors associated with PALN relapse on multivariate analysis. The 5-year PALN recurrence rate in patients with a SCC-Ag level >40 ng/mL, SCC-Ag level of 20-40 ng/mL, parametrial score of 4-6, pelvic lymphadenopathy, and no risk factors was 57%, 22%, 34%, 37%, and 9%, respectively. Conclusions: Patients with squamous cell carcinoma of the uterine cervix and a high SCC-Ag level, pelvic lymphadenopathy, or advanced PM involvement were predisposed to PALN recurrence after definitive radiotherapy. More intensive follow-up schedules are suggested for early detection and salvage in high-risk patients.

    Gynecologic radiation oncologists have long desired a single unit by which radiation doses to specific reference points in the pelvis can be summed. The Patterns of Care Studies, Marcial's 1976 report to the Conference on Radiation Oncology of the American Cancer Society, and other radiation oncologists advise summed doses to Point A, Point B, or the pelvic side wall. Since there is a difference in the biologic effect of high intensity, long time interval teletherapy and low intensity, short time interval brachytherapy, the rad dose obtained from each modality cannot be simply added. Ellis and Sorenson in the Nominal Standard Dose (NSD) concept have described radium conversion factors that can be used to normalize brachytherapy rads at selected reference points to equivalent teletherapy rad. The two rad doses can then be summed. A simple method found useful in 50 cases of carcinoma of the cervix, and used with a computer or readily available reference tables and with any radium system, is described and discussed. Further clinical uses of the method are suggested. PMID:7365825

    Twenty-two patients with biopsy-proved para-aortic lymph node metastases from carcinoma of the cervix (15 patients) or endometrium (7 patients) received a median dose of 5,000 rad/25 fractions. Para-aortic nodal metastases were controlled in 77% of cases. Control was significantly lower following radical retroperitoneal lymph node dissection than less extensive sampling procedures. Obstruction of the small bowel developed in 3 patients with tumor recurrence in the para-aortic region. Eight of the 10 patients who were disease-free at 2 years received >5,000 rad. Three patients were still alive without disease at 129, 63, and 60 months, respectively. The 5-year disease-free survival rate was 40% for cervical cancer and 60% for endometrial cancer: in the former group, it was significantly different depending on whether the para-aortic nodes were irradiated (40%) or not (0%). The authors suggest that 5,000-5,500 rad in 5-5.5 weeks is well tolerated and can control aortic nodal metastases in cervical and possibly endometrial cancer.

    Patient-derived xenograft (PDX) models of cancer are considered to reflect the biology and treatment response of human tumors to a larger extent than xenograft models initiated from established cell lines. The characterization of a panel of four novel PDX models of cervical carcinoma of the uterine cervix is described in this communication. The outcome of treatment differed substantially among the donor patients, and the PDX models were found to mirror the histology, aggressiveness, and metastatic propensity of the donor patients' tumors. Two of the models (BK-12 and LA-19) were highly metastatic, one model (ED-15) was poorly metastatic, and one model (HL-16) was non-metastatic. The primary tumors of the two highly metastatic models showed high density of intratumoral lymphatics, whereas the other two models did not develop intratumoral lymphatics. The potential of the models to metastasize to lymph nodes was associated with high expression of both angiogenesis-related genes and cancer stem cell-related genes. The models may be highly valuable for studying mechanisms linking lymph node metastasis to lymphangiogenesis, hemangiogenesis, and the presence of cancer stem cells.

    To assess the feasibility of reirradiation with image-based high-dose-rate brachytherapy in previously irradiated patients with recurrent carcinoma of uterine cervix. Thirty previously irradiated patients diagnosed with central recurrence were treated with reirradiation. Martinez Universal Perineal Implant Template was used in 24 patients and Vienna applicator in 6 patients. Median interval between two radiation schedules was 25 months. Median delivered dose was 42 Gy equivalent dose at 2 Gy (EQD2; interquartile range, 37-46 Gy EQD2). All 30 patients tolerated reirradiation well. Complete response was seen in 23 (76%) patients. With a median followup of 25 months, 2-year local control, disease-free survival, and overall survival were 44%, 42%, and 52%, respectively. Fifteen patients developed local recurrences; Local control rate was significantly higher with doses >40 Gy EQD2 (52% vs. 34%; p = 0.05). Disease-free survival was better for patients with longer interval (>25 months) between two radiotherapy schedules. Grade III radiation proctitis and cystitis was seen in 3 patients each, and Grade II small bowel toxicity was seen in 3 patients. Reirradiation using high-dose-rate brachytherapy is feasible with acceptable outcomes in isolated local recurrence deemed unsuitable for surgery. The outcome is better with higher doses.

    From June, 1972, to December, 1976, 40 patients with FIGO (International Federation of Gynaecology and Obstetrics) Stage IIB carcinoma of the uterine cervix were entered into a prospective, double-blind, randomized study to evaluate the possible radiation-potentiating properties (i.e., improved survival) of the S-phase cell cycle-specific inhibitor of DNA synthesis, hydroxyurea. All patients were documented to be without aortic lymph node metastasis by pretherapy staging para-aortic lymphadenectomy. All 40 patients were followed up for longer than 5 years (5.2 to 9.2 years) or until death. The double-blind code was not broken until all patients had been followed up for a minimum of 2 to 5 years. Leukopenia (white blood cell count less than 2,500 mm3) was significantly increased in the patients given hydroxyurea as compared to those given placebo (P less than 0.0001). There was no statistically significant difference relative to anemia, thrombocytopenia, radiation-induced skin reaction, and radiation-induced intestinal reaction between the patients given placebo or those given hydroxyurea. Life-table survival for the patients given hydroxyurea was 94% as compared to 53% for the patients given placebo (P . 0.006). Only one (5%) patient given hydroxyurea died of cervical cancer. Of the other patients who died in the group given hydroxyurea, all were confirmed by postmortem examination to have been without recurrent cervical cancer. In contrast, 45% (nine) of the patients given placebo died of cervical cancer.

    Like many other solid tumors, cervical cancer contains a heterogeneous population of cancer cells. Several investigators have identified putative stem cells from solid tumors and cancer cell lines via the capacity to self renew and drive tumor formation. The aim of this study was to identify and characterize a cancer stem-like cell population from primary carcinoma of the cervix uteri. Cervical carcinoma from 19 patients staged I-II following International Federation of Gynecology and Obstetrics (FIGO) criteria were disaggregated and subjected to growth conditions selective for stem cells. Eight of nineteen tumor-derived cultures encompassed stem-like cells capable of self-renewal, extensive proliferation as clonal non-adherent spherical clusters. Cell markers of spheroid were identified as CD44+CK17+. Cell survival assays showed the sphere-forming cells were only 48% inhibited by doxorubicin whereas 78% inhibited by paclitaxel. Chemo-resistance may partly attribute to the exclusive expression of ABC transporter. To investigate the tumorigenicity of these stem-like cells, xenoengraftment of 10(5) dissociated spheroid cells allowed full recapitulation of the original tumor, whereas the same amount of tumor cells without non-adherent spheroid selection remained non-tumorigenic. Stemness properties of these spheroid cells were further established by reverse transcription-PCR and Western blotting, demonstrating the expression of embryonic and adult stemness-related genes (Oct-4, Piwil2, C-myc, Stat3 and Sox2). Based on these findings, we assert that cervical cancer contain a subpopulation of tumor initiating cells with stem-like properties, thus facilitating the approach to therapeutic strategies aimed at eradicating the tumorigenic subpopulation within cervical cancer.

  18. Adjuvant therapy after primary surgery for stage I-IIA carcinoma of the cervix.

    Radical hysterectomy and bilateral pelvic lymph node dissection is commonly used as a primary management option for treatment of stage IB/IIA carcinoma of the cervix. Overall cure rates approach 85%. However, a spectrum of relapse risk exists, depending on the presence or absence of primary tumor and nodal-related prognostic factors. Known factors include number and location of lymph nodes; size of primary, deep invasion in the cervix; capillary lymphatic space involvement; occult parametrial involvement; and positive or close surgical margins. Biologic determinants have yet to be identified. No systematic analysis has examined various combinations of prognostic factors to precisely define associated levels of risk and to predict the sites of relapse. Decreased local control and survival rates in some high-risk subgroups, usually those with nodal positivity, has led to the exploration of adjuvant therapies. Compiled data from retrospective series have defined the overall patterns of failure. Seventy-two percent of those relapsing have a component of pelvic failure, while 42% experience relapse in the pelvis alone. Fifty-eight percent have a component of distant failure but only 28% have distant disease alone. Adjuvant treatment options include pelvic radiotherapy, extended-field radiotherapy, chemoradiotherapy, and chemotherapy. Trials of adjuvant chemotherapy are too few to evaluate the use of available agents. Pelvic radiotherapy has been shown to reduce the relapse risk when surgical margins are close or positive. It also reduces the risk of pelvic relapse and improves the relapse-free interval but has no apparent impact on overall survival in the groups that have been selected for treatment. The apparent lack of benefit may relate to the choice of patients with nodal involvement who, despite high risk of pelvic failure, most likely have a predominant pattern of distant failure. Maximization of the survival benefit of pelvic radiotherapy requires the

    Uterine cervix cancer is the second most common malignancy in women worldwide with human papillomavirus (HPV) as the etiologic factor. The two main histological variants, squamous cell carcinomas (SCC) and adenocarcinomas (AC), resemble the cell morphology of exocervix and endocervix, respectively. Cancer metabolism is a cancer hallmark conditioned by the microenvironment. As uterine cervix homeostasis is dependent on lactate, we hypothesized lactate plays a role in uterine cervix cancer progression. Using in vitro (SiHa-SCC and HeLa-AC) and BALB-c/SCID models, we demonstrated that lactate metabolism is linked to histological types, with SCC predominantly consuming and AC producing lactate. MCT1 is a key factor, allowing lactate consumption and being regulated in vitro by lactate through the FOXM1:STAT3 pathway. In vivo models showed that SCC (SiHa) expresses MCT1 and is dependent on lactate to grow, whereas AC (HeLa) expresses MCT1 and MCT4, with higher growth capacities. Immunohistochemical analysis of tissue microarrays (TMA) from human cervical tumors showed that MCT1 expression associates with the SCC type and metastatic behavior of AC, whereas MCT4 expression concomitantly increases from in situ SCC to invasive SCC and is significantly associated with the AC type. Consistently, FOXM1 expression is statistically associated with MCT1 positivity in SCC, whereas the expression of FOXO3a, a FOXM1 functional antagonist, is linked to MCT1 negativity in AC. Our study reinforces the role of the microenvironment in the metabolic adaptation of cancer cells, showing that cells that retain metabolic features of their normal counterparts are positively selected by the organ's microenvironment and will survive. In particular, MCT1 was shown to be a key element in uterine cervix cancer development; however, further studies are needed to validate MCT1 as a suitable therapeutic target in uterine cervix cancer.

    Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix. Under a tentative diagnosis of cervical cancer, surgery was performed. Although a freshly resected specimen initially showed no tumorous lesion in the cervical mucosa, cutting of the mucosa revealed a solid tumor with a final diagnosis of CCC. The findings of aggregation of hemosiderin-laden macrophages and ectopic endometrium adjacent to the tumor strongly suggest that this tumor arose from cervical endometriosis.

All patients received similar doses of radiation using combination intracavitary radioactive isotopes and external therapy. Patients who received heat therapy in combination with radiation therapy did not have increased acute or chronic complications of normal tissues. Local tumor control was superior when regional heat therapy was given; however, long-term absolute survival rates were not affected as the survival rate at 5 years was not statistically different in any of the three treatment groups.

    Purpose Intensity modulated radiation therapy (IMRT) compensation based on 3D high-dose-rate (HDR) intracavitary brachytherapy (ICBT) boost technique (ICBT + IMRT) has been used in our hospital for advanced cervix carcinoma patients. The purpose of this study was to compare the dosimetric results of the four different boost techniques (the conventional 2D HDR intracavitary brachytherapy [CICBT], 3D optimized HDR intracavitary brachytherapy [OICBT], and IMRT-alone with the applicator in situ). Material and methods For 30 patients with locally advanced cervical carcinoma, after the completion of external beam radiotherapy (EBRT) for whole pelvic irradiation 45 Gy/25 fractions, five fractions of ICBT + IMRT boost with 6 Gy/fractions for high risk clinical target volume (HRCTV), and 5 Gy/fractions for intermediate risk clinical target volume (IRCTV) were applied. Computed tomography (CT) and magnetic resonance imaging (MRI) scans were acquired using an in situ CT/MRI-compatible applicator. The gross tumor volume (GTV), the high/intermediate-risk clinical target volume (HRCTV/IRCTV), bladder, rectum, and sigmoid were contoured by CT scans. Results For ICBT + IMRT plan, values of D90, D100 of HRCTV, D90, D100, and V100 of IRCTV significantly increased (p < 0.05) in comparison to OICBT and CICBT. The D2cc values for bladder, rectum, and sigmoid were significantly lower than that of CICBT and IMRT alone. In all patients, the mean rectum V60 Gy values generated from ICBT + IMRT and OICBT techniques were very similar but for bladder and sigmoid, the V60 Gy values generated from ICBT + IMRT were higher than that of OICBT. For the ICBT + IMRT plan, the standard deviations (SD) of D90 and D2cc were found to be lower than other three treatment plans. Conclusions The ICBT + IMRT technique not only provides good target coverage but also maintains low doses (D2cc) to the OAR. ICBT + IMRT is an optional technique to boost parametrial region or tumor of large size and irregular shape

    Adenoid basal hyperplasia is an underrecognized cervical lesion, resembling adenoid basal carcinoma, except the absence of deep invasion into the stroma. We report a series of 10 cases, all extending less than 1 mm from the basement membrane. Our results support the hypothesis that adenoid basal hyperplasia arises from reserve cells of the cervix. Lesions were found close to the squamocolumnar junction, in continuity with the nearby subcolumnar reserve cells. They shared the same morphology and immunoprofile using a panel of 4 antibodies (keratin 5/6, keratin 14, keratin 7 and p63) designed to differentiate reserve cells from mature squamous cells and endocervical columnar cells. We detected no human papillomavirus infection by in situ hybridization targeting high-risk human papillomavirus, which was concordant with the absence of immunohistochemical p16 expression. We demonstrated human papillomavirus infection in 4 (80%) of 5 adenoid basal carcinoma, which is in the same range as previous studies (88%). Thus, adenoid basal hyperplasia should be distinguished from adenoid basal carcinoma because they imply different risk of human papillomavirus infection and of subsequent association with high-grade invasive carcinoma. In our series, the most reliable morphological parameters to differentiate adenoid basal hyperplasia from adenoid basal carcinoma were the depth of the lesion and the size of the lesion nests. Furthermore, squamous differentiation was rare in adenoid basal hyperplasia and constant in adenoid basal carcinoma. Finally, any mitotic activity and/or an increase of Ki67 labeling index should raise the hypothesis of adenoid basal carcinoma.

    Cervical cancer mortality has declined by 74% in the United States since the implementation of the Papanicolaou (Pap) test. Nevertheless, more than 12,000 US women annually develop cervical cancer, and squamous cell carcinoma (SqCa) remains the predominant cervical malignancy. To evaluate screening techniques used in the detection of SqCa of the cervix and provide insights regarding which technique(s) is (are) most efficacious in our study population. We retrospectively reviewed all available cytologic, human papillomavirus (HPV), and histologic malignancy burden data from patients diagnosed with SqCa. The clinical data were collected from 2 geographically and socioeconomically diverse hospital systems. Cases in which identified patients had a Pap test with a negative result/unsatisfactory specimen within 5 years of SqCa tissue diagnosis were considered Pap test screening failures. Cases in which patients were diagnosed with HPV-negative SqCa were considered HPV screening failures. Eighty-eight cases (patients' ages ranging from 19 to 73 years) were identified. Of those, cytologic history was available for 64 cases present in our electronic medical history record. Three cases were cytology screening failures (one being an unsatisfactory specimen) and 3 cases were HPV screening failures (one being the cytologic unsatisfactory case). Although measuring sensitivity in practice has limitations, we calculated the SqCa detection sensitivity at 95.3% by Pap test alone and 97% when HPV DNA testing was incorporated. Our results highlight the necessity of combining Pap and HPV testing. Although the number of cases identified is relatively small, our data suggest detection failures will decrease as the practice of combining HPV and Pap testing increases.

    Women with carcinoma in situ (CIS) of the cervix uteri, notified to the population-based Cancer Registry of the Swiss Canton of Vaud between 1974 and 1993, were actively followed up to 31 December 1993 for the occurrence of subsequent invasive neoplasms. Among 2190 incident cases of CIS, followed for a total of 22,225 person-years, 95 metachronous cancers were observed vs 77.9 expected, corresponding to a significant standardised incidence ratio (SIR) of 1.2. Ten cases of invasive cervical cancer were observed vs 3.0 expected (SIR = 3.4, P < 0.01), the excess being larger in the first 10 years since CIS diagnosis. A total of 11 cases of four major tobacco-related sites (lung, mouth or pharynx, oesophagus and urinary bladder) were observed vs 5.1 expected, corresponding to a significant SIR of 2.2. The excess was observed > or = 10 years after CIS diagnosis. There was also an excess of non-melanomatous skin cancers (29 observed, 16.9 expected, SIR = 1.7; P < 0.01), but not of skin melanoma and of any of the other neoplasms considered, including breast and corpus uteri. This population-based study, therefore, finds an excess of invasive cervical cancer in the short term after CIS diagnosis, and a medium- to long-term excess risk of tobacco-related and non-melanomatous skin neoplasms. These findings are discussed in terms of increased surveillance and case ascertainment after CIS, and of potential shared risk factors (tobacco and/or viral infections). PMID:8883426

    A randomized, controlled study was performed in patients with high-risk, untreated squamous cell carcinoma of the uterine cervix to evaluate the adjunctive use of viral oncolysate (VO) prepared from the SW756 cell line. Seventy-five patients were stratified by tumor volume and randomized to receive radiation therapy (RT) alone or RT plus intradermal immunization with VO. Fifty-one (68%) patients relapsed with a median survival (MS) of 29.1 months and a median progression-free interval (MPFI) of 18.0 months. No differences in MS or median PFI were observed by treatment arm or site of relapse, although a trend toward improved MS and median PFI in patients with small-volume primary lesions was suggested. Serum surface-binding antibody activity (greater than or equal to 1:8) to the SW756 cell line was detected in 14 of 41 unselected patients prior to therapy. Virus hemagglutination inhibitory activity (greater than or equal to 1:8) was detected in 37 of 41 patients before treatment. four-fold increases in titer were observed to the SW756 cell line in 83% and to influenza in 74% of patients tested after immunization. Preirradiation measurements of phytohemagglutinin-induced blastogenesis by the relative proliferation index (RPI) method in 39 patients revealed RPI values less than 0.58 in nine patients, eight of whom relapsed. At 3-6 months after the initiation of irradiation, 32 of 39 patients had values less than 0.58. Patients in the RT group with values less than 0.58 had significantly more relapses than those who received RT plus VO.

    Objective Small cell carcinoma of the uterine cervix (SMCC) is extremely rare, and an aggressive disease that proliferates rapidly. It was often reported that the diagnostic accuracy of cytologic smears in diagnosing SMCC was low. This is a report of the Severance Hospital experience with the patients suffering from SMCC. Methods Twenty-seven patients with small cell carcinoma of the uterine cervix were diagnosed and treated at the Severance Hospital from November 1991 to January 2010. The data were analyzed retrospectively, based on the available charts and pathology reports. Various fields, such as chief complaints and symptoms present at first clinic visit, age, International Federation of Obstetrics and Gynecology (FIGO) clinical stage, treatment modality, the 5-year overall survival rate, and recurrence rate were investigated. Results Among the 27 patients diagnosed with small cell carcinoma of the uterine cervix, 18 of them (66.7%) presented with symptoms, including vaginal bleeding, at the first clinic visit, and the remaining 9 patients (33.3%) showed abnormal Pap smear screening in the process of their routine health check-up. The median age of the patients was 54 years (range, 24 to 77 years). FIGO stage IIB was the most common stage (11 of 27 patients). The 5-year overall survival rate of 21 patients, who could be followed up, was 57.2%. Six patients showed recurrence after remission, and the mean disease free interval of them was 9.2 months (range, 6 to 11 months). Abnormal Pap smear screening results of 9 patients was investigated, and the diagnostic accuracy of the cytologic findings was 22.2%. Conclusion Our study was consistent with the concept that Pap smear screening might not be helpful in early diagnosis of SMCC considering its low diagnostic accuracy. Further large-scale multicenter prospective studies are definitely needed in order to produce abundant information about optimal therapy and diagnosis. PMID:21607094

    Purpose: To examine the effectiveness of concomitant intra-arterial infusion chemotherapy (IAIC) using cisplatin (CDDP) with radiotherapy for Stage III squamous cell carcinoma of the cervix. Materials and Methods: We analyzed 29 cases of Stage III squamous cell carcinoma of the uterine cervix treated with radiotherapy and IAIC of CDDP from 1991 to 2006. External-beam therapy was given to the whole pelvis using four opposing parallel fields with an 18-MV linear accelerator unit. A central shield was used after 30-40 Gy with external whole-pelvic irradiation, and the total dose was 50 Gy. High-dose-rate brachytherapy was given with {sup 192}Ir microSelectron. The dose at Point A was 6 Gy per fraction, 2 fractions per week, and the total number of fractions was either 3 or 4. Two or three courses of IAIC were given concomitantly with CDDP 120 mg or carboplatin 300 mg. Results: We confirmed excellent medicine distribution directly by using computed tomographic angiography. The 5-year overall survival rate for Stage III patients was 62%, the cause-specific survival rate was 70%, and the local relapse-free survival rate was 89%. Local recurrence, distant metastasis, and occurrences of both were 7%, 38%, and 3%, respectively. The incidence of severe acute hematologic adverse reactions (Grade {>=}3) was 27% for all patients; however, all recovered without interruption of radiotherapy. Severe nonhematologic effects (Grade {>=}3) were 3%, including nausea and ileus. Only 1 patient's radiotherapy was interrupted for a period of 1 week because of ileus. Severe late complication rates (Grade {>=}3) for the bladder, rectum, and intestine were 3%, 3%, and 10%, respectively. Conclusion: A combination of IAIC and systemic chemotherapy should be considered to improve the prognosis of patients with Stage III squamous cell carcinoma of the cervix.

    To determine the response rate and associated toxicity of weekly CPT-11 in squamous carcinoma of the cervix. From October 1994 to May 1996, the Gynecologic Oncology Group (GOG) conducted a Phase II trial in patients with recurrent squamous cervix carcinoma. The schedule employed weekly x4 intravenous CPT-11 at 125 mg/m2 followed with a 2-week rest, to be repeated until disease progression or unacceptable toxicity. Eligibility criteria were a GOG performance status of 0-2, adequate bone marrow reserve, adequate liver function, and serum creatinine <2 mg%. None of the patients had received prior chemotherapy other than radiation sensitizers. Standard GOG toxicity and response criteria were used. Fifty-four patients were entered into the trial. Three patients were ineligible because of wrong cell type (N = 2) or inadequate pathology material (N = 1). Two were inevaluable because of inadequate trial of drug. An additional 4 patients were inevaluable for response. Thus, 49 were evaluable for toxicity and 45 were evaluable for response. The median age of patients was 45 years (range, 29-71 years). The median number of weekly doses delivered was 7 (range, 1-46). The incidence of grade 4 neutropenia and anemia was 6.1 and 4.1%, respectively. Nineteen patients (38.8%) developed gastrointestinal (GI) toxicity including 8 with grade 3 and 11 with grade 4 severity. The overall response rate was 13.3% (6/45). There was 1 patient death from GI toxicity. There was one complete response of 8.8 months duration and 5 partial responses. OFFis schedule of CPT-11 exhibits modest activity with moderate toxicity in patients with recurrent squamous carcinoma of the cervix. Copyright 1998 Academic Press.

    Advances in radiation techniques and increased dosage have improved the cure rate of patients with cancer of the cervix to 65 percent. Associated with this increased dosage (betatron, 5,250 r and intracavitary 137-cesium, 4,000 r at point A) has been a serious complication incidence of 10 percent. Major intestinal complications usually become manifest within an 8 to 24 month period following radiation. Few are associated with tumor and the majority are amenable to surgical correction. Rectosigmoid stenosis is a common and frequently unrecognized complication. The 8 to 12 cm. segment of rectosigmoid, with its rigid wall and narrowed lumen, can be recognized on barium examination. The symptoms are those on incomplete obstruction and deterioration, frequently confused with tumor progression. Thirty-one patients have been treated by resection and low anterior anastomosis with relief of symptoms. Rectosigmoid stenosis progressing to necrosis, perforation, or fistula (an additional 29 patients) is treated best by the Hartmann operation as a first stage. This procedure has been less complicated than either colostomy alone or resection and anastomosis. Fifteen patients with low level rectovaginal fistula or stenosis were treated by defunctioning sigmoid colostomy. A loop transverse colostomy was unsatisfactory. Ileorectovaginal fistulas occurred in an additional six patients. Preoperative investigation should establish the presence or absence of an ileal component in all fistulas. Radiation ileitis is rare as an isolated finding but frequently is associated with severe rectosigmoid damage. Surgical treatment is seldom necessary but, if indicated (ten patients), resection appears to be preferable to bypass.

    Angiokeratoma including vulvar angiokeratoma is a very rare complication of radiation. Exact incidence is still unknown, we report a case that developed radiation-induced angiokeratoma of skin in the vulvar region along with other late radiation sequelae in the form of bone fracture, new bone formation, bone marrow widening, muscle hypertrophy, and subcutaneous fibrosis, 18 years after radiotherapy to the pelvic region for the treatment of carcinoma cervix. All these late radiation sequel are rare to be seen in a single patient, and none of the case reports could be found in the world literature. PMID:27057045

    Radical radiation therapy used for carcinoma of the cervix will ablate ovarian function. Since January 1986, our policy has been to administer oral combination oestrogen-progesterone replacement hormonal therapy to all premenopausal patients undergoing radical radiation with or without synchronous chemotherapy, for invasive cervix cancer. Five out of 22 (23%) such patients unexpectedly experienced between one and four episodes of cyclical per vaginal bleeding after the completion of radiation therapy. Bleeding episodes occurred in the absence of persistent tumor or radiation reaction, and suggest persisting endometrial response to exogenous hormonal stimulation. Uterine activity was temporarily retained in these five patients despite a minimal endometrial surface dose of between 4800 and 6490 cGy. The limited number of cycles before bleeding spontaneously ceased may represent the slow death of endometrial cells subsequent to radiation or radiochemotherapy treatment, and has not previously been described. In view of the paucity of data on the radiosensitivity of normal endometrium, we have carefully examined these patients who appear to have retained endometrial sensitivity to hormonal stimuli after radical radiation-chemotherapy for uterine cervix cancer.

    To analyse the dosimetric parameters of Co-60 based high dose rate (HDR) brachytherapy plans for patients of carcinoma uterine cervix. Co-60 high dose rate (HDR) brachytherapy unit has been introduced in past few years and is gaining importance owing to its long half life, economical benefits and comparable clinical outcome compared to Ir-192 HDR brachytherapy. A study was conducted on ten patients with locally advanced carcinoma of the uterine cervix (Ca Cx). Computed tomography (CT) images were taken after three channel applicator insertions. The planning for 7 Gray per fraction (7 Gy/#) was done for Co-60 HDR brachytherapy unit following the American Brachytherapy Society (ABS) guidelines. All the patients were treated with 3# with one week interval between fractions. The mean dose to high risk clinical target volumes (HRCTV) for D90 (dose to 90% volume) was found to be 102.05% (Standard Deviation (SD): 3.07). The mean D2cc (dose to 2 cubic centimeter volume) of the bladder, rectum and sigmoid were found to be 15.9 Gy (SD: 0.58), 11.5 Gy (SD: 0.91) and 4.1 Gy (SD: 1.52), respectively. The target coverage and doses to organs at risk (OARs) were achieved as per the ABS guidelines. Hence, it can be concluded that the Co-60 HDR brachytherapy unit is a good choice especially for the centers with a small number of brachytherapy procedures as no frequent source replacement is required like in an Ir-192 HDR unit.

    Background The glycosylation of a great number of molecules, glyco-protein or glycolipids, has been of interest for decades. Objective To compare the expressive patterns of the isoantigenic determinants of histo-blood groups ABH and Lewis in squamous and simple epithelium and in precursors and cancers of the cervix. Methods A total of 36 lesions and neoplasms (10 LG-SIL, 16 HG-SIL and 10 invasive carcinomas) have been studied with immunohistochemical techniques, using monoclonal antibodies (MoAb BG1 to BG8) for precursor chains, blood-group ABH and Lewis group Lea, Leb, Lex, and Ley, and four types of lectins. In addition, we have studied the expression of p53 protein and PCNA, establishing the rate of proliferation of each lesion. Using PCR techniques, we have also detected part of the intron of the E6 gene of HPV-16. Results In the invasive cervical carcinomas, we observed a loss of expression of the Lex antigen (p < 0.01). With regard to the progression of the different lesions studied, we found alterations in the patterns of expression of the antigens of the ABH and Lewis blood groups. There was a tendency towards a loss of expression and heterogeneous patterns in the more advanced lesions, as well as over-expression of the Ley antigens. With PCNA, we established a proliferative rate which tended to be greater in relation to the progression of the cervix neoplasms. Conclusion These results indicate that there is a relation between the losses of histo-blood groups and the progression of the squamous intraepithelial lesions. PMID:18786253

    The main purpose of this study is to know the effect of three different photon energies viz., 6, 10, and 15 mega voltage (MV) on RapidArc (RA) planning for deep-seated cervix tumor and to develop clinically acceptable RA plans with suitable photon energy. RA plans were generated for 6, 10, and 15 MV photon energies for twenty patients reported with cervix carcinoma. RA plans were evaluated in terms of planning target volume (PTV) coverage, dose to organs at risk (OARs), conformity index (CI), homogeneity index (HI), gradient measure, external volume index of dose distribution produced, total number of monitor units (MUs), nontumor integral dose (ID), and low dose volume of normal tissue. A two-sample paired t-test was performed to compare the dosimetric parameters of RA plans. Irrespective of photon energy used for RA planning, plans were dosimetrically similar in terms of PTV coverage, OARs sparing, CI and HI. The numbers of MUs were 13.4 ± 1.4% and 18.2 ± 1.5% higher and IDs were 2.7 ± 0.8% and 3.7 ± 0.9% higher in 6 MV plans in comparison to that in the 10 and 15 MV plans, respectively. V1Gy, V2Gy, V3Gy, and V4Gy were higher in 6 MV plans in comparison to that in 10 and 15 MV plans. Based on this study, 6 MV photon beam is a good choice for RA planning in case of cervix carcinoma, as it does not deliver additional exposure to patients caused by photoneutrons produced in high energy beams.

    Purpose: To compare bladder and rectum doses with the use of a bladder–rectum spacer balloon (BRSB) versus standard gauze packing in the same patient receiving 2 high-dose-rate intracavitary brachytherapy fractions. Methods and Materials: This was a randomized study to compare the reduction in bladder and rectum doses with the use of a BRSB compared with standard gauze packing in patients with carcinoma of the cervix being treated with high-dose-rate intracavitary brachytherapy. The patients were randomized between 2 arms. In arm A, vaginal packing was done with standard gauze packing in the first application, and BRSB was used in the second application. Arm B was the reverse of arm A. The International Commission for Radiation Units and Measurement (ICRU) point doses and doses to 0.1-cm{sup 3}, 1-cm{sup 3}, 2-cm{sup 3}, 5-cm{sup 3}, and 10-cm{sup 3} volumes of bladder and rectum were compared. The patients were also subjectively assessed for the ease of application and the time taken for application. Statistical analysis was done using the paired t test. Results: A total of 43 patients were enrolled; however, 3 patients had to be excluded because the BRSB could not be inserted owing to unfavorable local anatomy. Thus 40 patients (80 plans) were evaluated. The application was difficult in 3 patients with BRSB, and in 2 patients with BRSB the application time was prolonged. There was no significant difference in bladder doses to 0.1 cm{sup 3}, 1 cm{sup 3}, 2 cm{sup 3}, 5 cm{sup 3}, and 10 cm{sup 3} and ICRU bladder point. Statistically significant dose reductions to 0.1-cm{sup 3}, 1-cm{sup 3}, and 2-cm{sup 3} volumes for rectum were observed with the BRSB. No significant differences in 5-cm{sup 3} and 10-cm{sup 3} volumes and ICRU rectum point were observed. Conclusion: A statistically significant dose reduction was observed for small high-dose volumes in rectum with the BRSB. The doses to bladder were comparable for BRSB and gauze packing.

    From 1988 to May, 1992, there were 286 patients with pathology-proved carcinoma of the uterine cervix referred to Chang Gung Memorial Hospital, Kaohsiung to receive definite radiotherapy. Sixty-one (21%) patients were found to develop distant metastasis after radiotherapy for at least 2 years follow-up. By FIGO stage, the incidence of distant metastasis was as follows: I :2/39, II a:1/19, II b:20/118, III :34/101, IV a: 4/9. Eighty-five percent patients (52/61) began to develop distant metastasis within the first 2 years after radiotherapy. Twenty-three patients developed single organ metastasis, and 38 patients developed multiple organ metastasis. Lymph nodes (38 patients), lung (28 patients), bone (27 patients), and abdomen (20 patients) were the common sites of distant metastasis. Lymph nodes metastasis occurred most often at supraclavicular lymph nodes (15 patients), para-aortic lymph nodes (18 patients), and inguinal lymph nodes (5 patients). Spine (23 patients), especially the lumbar spine (20 patients) was the most common site of bony metastasis. Abdominal metastasis occurred in abdominal cavity (15 patients) or liver (5 patients). The incidence of metastasis within the first two years after radiotherapy was lung: 75% (21/28), bone: 62% (18/29), left supraclavicular lymph nodes: 60% (9/15), para-aortic lymph nodes: 72% (13/18), intra-abdominal cavity: 86% (13/15), liver: 66% (2/3), brain: 0% (0/4). The 2-year actuarial survival rate for the 61 patients after developing distant metastasis was 14%, with a median survival time of 6.4 months. There was no significant difference in survival when comparing patients with single organ metastasis and with multiple organ metastasis (p > 0.05), or patients with distant metastasis alone and with distant metastasis combined with local recurrence (p > 0.05). Otherwise, after distant metastasis twenty-three patients receiving chemotherapy or radiotherapy had a significantly higher 2-year survival rate than 38 patients

    In our center limited centro pelvic invasive carcinomas of the uterine cervix (less than 4 cm) are treated with brachytherapy and surgery. With these therapeutic modalities no residual carcinoma was observed for 80% of the patients. The purpose of this study was to evaluate our results with this treatment, and to evaluate the prognostic value of the pathological status of the cervix. From 1976 to 1987 we have treated 115 patients with these modalities. Staging system used was the FIGO classification modified for Stage II (divided in early Stage II and late Stage II). Patients were Stage IB (70 cases) and early Stage II (45 cases); 60 Gy were delivered with utero vaginal brachytherapy before any treatment. Six weeks later a radical hysterectomy with pelvic lymphadenectomy was performed. Twenty-one patients with positive nodes received a pelvic radiotherapy (45 to 55 Gy). Local control rate was 97% (100% for Stage IB and 93% for early Stage II). Uncorrected 10-year actuarial survival rate was 96% for Stage IB and 80% for early Stage II patients. No treatment failure was observed for Stage IB patients. Ninety-two patients (80%) had no residual carcinoma in the cervix (group 1) and 23 patients (20%) had a residual tumor (group 2). The sterilization rate of the cervix was 87% for Stage IB tumors versus 69% for early Stage II, and was 82% for N- patients versus 68% for N+ patients. Ten year actuarial survival rate was 92% for group 1 and 78% for group 2 (p = 0, 1). Grade 3 complications rate was 6%. We conclude that brachytherapy + surgery is a safe treatment for limited centro pelvic carcinomas of the uterine cervix (especially Stage IB) and that pathological status of the cervix after brachytherapy is not a prognostic factor.

    Hepatocellular carcinoma (HCC) is an aggressive malignancy, resulting as the third cause of death by cancer each year. The management of patients with HCC is complex, as both the tumour stage and any underlying liver disease must be considered conjointly. Although surveillance by imaging, clinical and biochemical parameters is routinely performed, a lot of patients suffering from cirrhosis have an advanced stage HCC at the first diagnosis. Advanced stage HCC includes heterogeneous groups of patients with different clinical condition and radiological features and sorafenib is the only approved treatment according to Barcelona Clinic Liver Cancer. Since the introduction of sorafenib in clinical practice, several phase III clinical trials have failed to demonstrate any superiority over sorafenib in the frontline setting. Loco-regional therapies have also been tested as first line treatment, but their role in advanced HCC is still matter of debate. No single agent or combination therapies have been shown to impact outcomes after sorafenib failure. Therefore this review will focus on the range of experimental therapeutics for patients with advanced HCC and highlights the successes and failures of these treatments as well as areas for future development. Specifics such as dose limiting toxicity and safety profile in patients with liver dysfunction related to the underlying chronic liver disease should be considered when developing therapies in HCC. Finally, robust validated and reproducible surrogate end-points as well as predictive biomarkers should be defined in future randomized trials. PMID:27678348

    We have chosen tumors of the uterine cervix as a model system to identify chromosomal aberrations that occur during carcinogenesis. A phenotype/genotype correlation was established in defined regions of archived, formalin-fixed, and hematoxylin/eosin-stained tissue sections that were dissected from normal cervical epithelium (n = 3), from mild (n = 4), moderate (n = 6), and severe dysplasias/carcinomas in situ (CIS) (n = 13), and from invasive carcinomas (n = 10) and investigated by comparative genomic hybridization. The same tissues were analyzed for DNA ploidy, proliferative activity, and the presence of human papillomavirus (HPV) sequences. The results show that an increase in proliferative activity and tetraploidization had occurred already in mildly dysplastic lesions. No recurrent chromosomal aberrations were observed in DNA extracted from normal epithelium or from mild and moderate dysplasias, indicating that the tetraploidization precedes the loss or gain of specific chromosomes. A gain of chromosome 3q became visible in one of the severe dysplasias/CIS. Notably, chromosome 3q was overrepresented in 90% of the carcinomas and was also found to have undergone a high-level copy-number increase (amplification). We therefore conclude that the gain of chromosome 3q that occurs in HPV16-infected, aneuploid cells represents a pivotal genetic aberration at the transition from severe dysplasia/CIS to invasive cervical carcinoma.

    The objective of this retrospective study was to analyze the clinical characteristics and prognosis of clear cell adenocarcinoma (CCA) in the post-diethylstilbestrol (DES) era and to evaluate the feasibility of fertility-preserving treatment. The records of 32 patients with CCAs who were treated at Peking Union Medical College Hospital from August 1986 to June 2012 were retrospectively reviewed. Three of the patients had undergone fertility-preserving treatment. The incidence of CCA among cervical adenocarcinomas was 15.2%. The median age was 38 years: 11 patients (34.4%) were diagnosed before 30 years of age and two (6.3%) after 70 years of age. Ten patients (31.2%) were nulliparous. No patient had been exposed to DES. Twenty-nine patients (90.6%) presented with obvious symptoms, and the cervix appeared abnormal in 26 patients (81.3%). Cervical Papanicolaou (Pap) tests were abnormal in all four patients in whom they were performed (three had high-grade squamous intraepithelial lesions and one had atypical squamous cells of undetermined significance). The distribution by stage was 56.3% stage I, 34.4% stage II, 6.3% stage III, and 3.1% stage IV. Treatments mainly included surgery for patients with stage I to IIA CCA and radiochemotherapy for patients with advanced CCA. The overall 5-year progression-free survival was 72.2%. Patients with stage I to IIA CCA had better 5-year progression-free survival than did patients with stage IIB to IV CCA (81.5% versus 40.0%, P=0.003). The three patients who had undergone fertility-preserving treatment had no recurrences. CCA may also affect adolescents and children without prior DES exposure, who are often misdiagnosed as having functional uterine bleeding. Radiotherapy appears to be effective for local control but to have no effect on distant recurrences. In our study, the prognosis of patients with early-stage CCA, including those who had undergone fertility-preserving treatment, was not inferior to that of patients with

    Objectives: To evaluate the efficacy and safety of erlotinib for the treatment of advanced hepatocellular carcinoma (HCC). Methods: A systematic literature search was undertaken in June 2015. Phase II/III trials of erlotinib for the treatment of advanced HCC were included. A descriptive analysis was applied. The study was conducted in College of Medicine, Honghui Hospital, Xi’an Jiaotong University, Xi’an, China, between June 2015 and January 2016. Results: Ten trials, comprising 9 phase II and one phase III trial, were included in the systematic review. The tumor response rate was 0% in 4 of the phase II trials, <10% in 3 of the phase II trials and the phase III trial, and >20% in 2 of the phase II trials. The disease control rate was 42.5-79.6% in most studies. Three studies reported a median progression-free survival (PFS) of 6.5-9.0 months, although PFS was <3.5 months in most studies. Most trials reported a median overall survival of 6.25-15.65 months. The most frequent grade 3/4 toxicities were fatigue (11.9%), diarrhea (10%), increased alanine and aspartate transaminases (7.3%), and rash/desquamation (6.9%). Conclusion: Erlotinib provides efficacious and well-tolerated treatment for advanced HCC. However, more detailed investigations of HCC pathogenesis and evaluation of sensitive patient subsets are needed to improve outcomes of patients with advanced HCC. Additional well-designed, randomized, controlled trials are needed to evaluate the efficacy and safety of erlotinib as monotherapy or combination with other drugs for advanced HCC. PMID:27761555

    Intracavitary Californium-252 combined with whole-pelvis photon radiotherapy was tested as the sole form of treatment for 22 patients with Stage IB carcinoma of the cervix. Californium-252 (Cf) is a fast neutron-emitting radioisotope currently being tested in trials of neutron brachytherapy (NT). The outcomes of the treated group of patients were traced for local tumor control, survival, patterns of failure, and complications. The Cf intracavitary therapy combined with whole-pelvis photon radiotherapy resulted in 95% 2-year and 91% 5-year actuarial survival. There were 9% Grade II-III complications by the Stockholm scale and 4% local failures. These results were obtained in an early clinical trial with a group of largely poor-risk patients with tumors of mean diameter of 4.3 cm.

    Eighty-four patients with previously untreated invasive carcinoma of the uterine cervix were treated by high-dose-rate intracavitary irradiation using a remotely controlled afterloading system (Ralstron) with or without external irradiation at the National Cancer Center Hospital, Tokyo, between 1977 and 1981. Survival rates and local control rates were comparable to those for 372 patients treated by low-dose-rate intracavitary irradiation with or without external irradiation from 1972 to 1981 at the hospital. The incidence of major complications was 5.1 and 2.4% for the patients treated by low-dose-rate intracavitary irradiation and by high-dose-rate irradiation, respectively. The results are comparable to those reported by other institutions. We have abandoned the conventional low-dose-rate intracavitary irradiation with the impression that the high-dose-rate remotely controlled afterloading system is a good alternative to the conventional one.

    Intracavitary Californium-252 combined with whole-pelvis photon radiotherapy was tested as the sole form of treatment for 22 patients with Stage IB carcinoma of the cervix. Californium-252 (Cf) is a fast neutron-emitting radioisotope currently being tested in trials of neutron brachytherapy (NT). The outcomes of the treated group of patients were traced for local tumor control, survival, patterns of failure, and complications. The Cf intracavitary therapy combined with whole-pelvis photon radiotherapy resulted in 95% 2-year and 91% 5-year actuarial survival. There were 9% Grade II-III complications by the Stockholm scale and 4% local failures. These results were obtained in an early clinical trial with a group of largely poor-risk patients with tumors of mean diameter of 4.3 cm.

    To evaluate pre-treatment haemoglobin and peripheral blood lymphocyte (PBL) counts as predictors of treatment outcome in cervix carcinoma treated with radical chemoradiation. Pre-treatment PBL counts and haemoglobin concentrations were retrieved from full blood count examinations from 111 patients who received concurrent chemoradiotherapy. Overall survival and relapse-free survival were obtained using the Kaplan-Meier method by ranking the data by median haemoglobin and PBL, singly and then in association. Their independence and significance as predictors of outcome were analysed using the Cox proportional hazard model. Survival rates were significantly higher in patients whose haemoglobin level or PBL counts were at or above the corresponding median value. At 5 years, rates of overall survival were 77% versus 41% (P = 0.0003) and 75% versus 42% (P = 0.002), when dichotomised around median haemoglobin and PBL, respectively. In multivariate and univariate analyses, both PBL and haemoglobin were independent and significant predictors for risk of death and relapse. Their predictive power was dramatically enhanced when the data were stratified into four groups by associating patients with haemoglobin ≥ median or < median with those whose PBL was ≥ or < median. Baseline PBL and haemoglobin seem to be strong, independent predictors of treatment outcome in carcinoma of the cervix, particularly if patient response is ranked using the predictors simultaneously. The hypothesis needs to be tested and, if confirmed, the markers should be used in combination to identify those at greater risk of failure who may benefit from additional therapy, with further validation in prospective trials offering treatment modification.

    The accurate dose delivery to the clinical target volume in radiotherapy can be affected by various pelvic tissues heterogeneities. An in-house heterogeneous woman pelvic phantom was designed and used to verify the consistency and computational capability of treatment planning system of radiation dose delivery in the treatment of cancer cervix. Oncentra 3D-TPS with collapsed cone convolution (CCC) dose calculation algorithm was used to generate AP/PA and box field technique plan. the radiation dose was delivered by Primus Linac (Siemens make) employing high energy 15 MV photon beam by isocenter technique. A PTW make, 0.125cc ionization chamber was used for direct measurements at various reference points in cervix, bladder and rectum. The study revealed that maximum variation between computed and measured dose at cervix reference point was 1% in both the techniques and 3% and 4% variation in AP/PA field and 5% and 4.5% in box technique at bladder and rectum points respectively.

    In November 2013, a woman with Herlyn-Werner-Wunderlich (HWW) syndrome was diagnosed with a locally advanced left cervical adenocarcinoma. The patient’s malformation consisted of two uteri with two cervixes, a obstructed vagina, and a left renal agenesis. Classification FIGO: stage IIIa because of infiltration of the inferior third of the vagina wall. Locoregional management comprised an infrarenal lateral aortic lymphadenectomy followed by concomitant radio-chemotherapy to the pelvic (inguinal, pelvic, and infrarenal para aortic nodes) volumes. A total of 50.4 Gy were delivered (1.8 Gy/fraction/day) to the node (inguinal, pelvic, and aortic infrarenal) and pelvic volume; a concomitant boost to the primary cervical tumor and macroscopic nodes to 59.92 Gy (2.14 Gy/fraction/day) was performed. 20 Gy were delivered with intracavitary brachytherapy boost with mold technique and a pulsed-dose-rate technique due to the rarity of this uterine malformation. After 30 months of follow-up, there was no evidence of locoregional or distant recurrence. PMID:28344607

    To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. The records of 1,096 patients treated with radiation therapy between 1960 and 1993 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. Of these, 983 (90%) were treated with curative intent and 113 were treated only to achieve palliation of symptoms. Of 907 patients who completed the intended curative treatment, 641 (71%) were treated with a combination of external beam irradiation (EBRT) and intracavitary irradiation (ICRT) and 266 (29%) were treated with EBRT only. The median duration of treatment for these 907 patients was 51 days. Between 1966 and 1980, only 52% of patients who completed treatment with curative intent received ICRT, compared with 92% of patients treated during 1981-1993, an increase that reflects an evolution in the philosophy of treatment for advanced tumors. In general, the intensity of ICRT correlated inversely with the dose of EBRT to the,central pelvis. Median follow-up of surviving patients was 134 months. For 983 patients treated with initial curative intent, disease-specific survival (DSS) was significantly worse for those who were < 40 years old, had experienced more than a 10% weight loss, or had a hemoglobin level < 10 g/dl before or during radiation therapy. Tumor factors that correlated with a relatively poor DSS were bilateral pelvic wall involvement, clinical tumor diameter > or = 8 cm, hydronephrosis, lower vaginal involvement, and evidence of lymph node metastases on lymphangiogram (p < 0.01 in all cases). For the 907 patients who completed treatment with curative intent, 641 who had ICRT had a DSS of 45% at 5 years, compared with 24% for those treated with EBRT alone (p < 0.0001). Those who received > 52 Gy of EBRT to the central pelvis had DSS rates of 27-34%, compared with 53% for patients treated with lower doses

    Basosquamous carcinoma is a rare cutaneous neoplasm that has caused considerable controversy as to its classification, pathogenesis, and management. To review and summarize current literature on the definition, pathogenesis, incidence, and management of basosquamous carcinoma. Through December 2015, an electronic search of the Pubmed database was performed using combinations of basosquamous carcinoma and metatypical basal cell carcinoma as search terms. A selection of 39 publications including case reports and series, retrospective studies, and systematic reviews of the literature were included. Descriptions of the definition of basosquamous carcinoma, clinical behavior, histopathological characteristics, current treatment therapies, and future advances are summarized. This systematic review provides a comprehensive overview of the current understanding of basosquamous carcinoma. Further study is required to elucidate the mechanisms driving the formation of this aggressive tumor.

    The Creteil method is a logical and simple system for intracavitary therapy of cervical and uterine cancer. The system is based on the use of a plastic cervico-vaginal moulage loaded with 0.5 mm diameter iridium 192 wire sources. The dimensions of both the moulage and the sources correspond to the size of the cervix being treated according to precisely defined relationships. The dose is specified on a reference isodose of a fixed value enclosing the pear-shaped target volume whose dimensions depend on the geometry of the sources. Source geometry in turn, depends on the size of the cervix. Thus, the dimensions of the target volume can be accurately predicted at the time of the application. Furthermore, treatment can be performed in a single application, with all sources having the same linear reference air kerma rate (or activity). Radioprotective measures are simple but effective and the patient is not subjected to the restrictions imposed by attachment to an after-loading apparatus. Our clinical results for early Stage T1 and T2a cervical tumors show excellent local control without major treatment complications or long term sequelae.

    The objective was to improve the design of the indwelling-intrauterine tube (IIUT) for brachy-radiotherapy of cervical cancer or sleeve, specifically one that would not require stitching to retain it properly in the uterus for periods of one to two weeks and to ensure hygiene by making them disposable, thinner, lighter, more economical, as well as more user-friendly for doctor and patient alike, and to satisfy new developments in terms of computed tomography (CT) and magnetic resonance imaging (MRI) compatibility. Injection moulding of carefully-selected medical grade polymers enabled ten improvements to the original sleeve; some were impossible to achieve with lathe turned items. The most important innovation was the addition of two delicate and very soft "wings" to the sleeves near the tips The sleeves were used in 50 consecutive patients with advanced carcinoma of the cervix. Metal markers could be eliminated by adding barium to the polymers. Not a single sleeve fell out in any of the 50 patients. No complications related to the use of the sleeves were observed. These sleeves are now used exclusively in this clinic. The improvements were very successful; none fell out and no suturing was required, which made them still more cost-effective and more comfortable to patients.

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    Purpose: To compare clinical behaviors and treatment outcomes between patients with squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix treated with radical hysterectomy (RH) and adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). Methods and Materials: A total of 318 Stage IB-IIB cervical cancer patients, 202 (63.5%) with SCC and 116 (36.5%) with AC/ASC, treated by RH and adjuvant RT/CCRT, were included. The indications for RT/CCRT were deep stromal invasion, positive resection margin, parametrial invasion, or lymph node (LN) metastasis. Postoperative CCRT was administered in 65 SCC patients (32%) and 80 AC/ASC patients (69%). Patients with presence of parametrial invasion or LN metastasis were stratified into a high-risk group, and the rest into an intermediate-risk group. The patterns of failure and factors influencing survival were evaluated. Results: The treatment failed in 39 SCC patients (19.3%) and 39 AC/ASC patients (33.6%). The 5-year relapse-free survival rates for SCC and AC/ASC patients were 83.4% and 66.5%, respectively (p = 0.000). Distant metastasis was the major failure pattern in both groups. After multivariate analysis, prognostic factors for local recurrence included younger age, parametrial invasion, AC/ASC histology, and positive resection margin; for distant recurrence they included parametrial invasion, LN metastasis, and AC/ASC histology. Compared with SCC patients, those with AC/ASC had higher local relapse rates for the intermediate-risk group but a higher distant metastasis rate for the high-risk group. Postoperative CCRT tended to improve survival for intermediate-risk but not for high-risk AC/ASC patients. Conclusions: Adenocarcinoma/adenosquamous carcinoma is an independent prognostic factor for cervical cancer patients treated by RH and postoperative RT. Concurrent chemoradiotherapy could improve survival for intermediate-risk, but not necessarily high-risk, AC/ASC patients.

    To study the magnitude of radiation cystitis following radiation therapy for carcinoma cervix, and propose an algorithm to decide on early diversion, with or without vesicovaginostomy. Women who developed radiation cystitis following radiotherapy for carcinoma cervix from January 1998 to December 2011 were included in this retrospective study. Electronic hospital records were analysed to document the presence of radiation cystitis. All women who developed evidence of radiation-induced cystitis, according to the common toxicity and Radiation Therapy Oncology Group criteria, were included in the study. We looked at transfusion requirements, number of hospital admissions, quality of life and cost involved. Chi-square tests were done where applicable. SPSS version 16 was used for analysis. Of the 902 patients who received radiation for carcinoma cervix in the 13-year period, 62 (6.87%) developed grade 3/4 cystitis. Twenty-eight of them underwent ileal conduit diversion, with 18 undergoing concomitant vesicovaginostomy. When compared with the patients who did not have diversion, the transfusion requirements, number of hospital admissions and quality of life had a statistically significant difference. Cost analysis of early diversion too showed a marginal benefit with early diversion. The limitation of the study was that it was retrospective in nature. In radiation cystitis, multiple hospital admissions and consequential increase in cost is the norm. In severe disease, early diversion is a prudent, cost-effective approach with good quality of life and early return to normal activity. © 2014 Royal Australasian College of Surgeons.

    The neuroendocrine small cell carcinoma of the cervix is a rare malignancy that has a poor prognosis due to early lymphatic and hematogenous spread. We herein report a case of a 27- year-old woman who was referred for initial staging of a neuroendocrine small cell carcinoma with previous unremarkable structural imaging. Ga-DOTATATE PET/CT revealed focal uptake at the primary tumor and in a solitary pelvic bone lesion suggestive of metastases that was further confirmed by CT-guided biopsy. Somatostatin receptor PET/CT may be a useful image modality for early detection of metastases to guide treatment in these patients.

    Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma.

    From January, 1967 to December, 1974, 325 patients with carcinoma of the uterine cervix were treated with a minimum of 4,000 rad whole pelvis irradiation plus intracavitary radium. These patients had large, sometimes massive, tumors. Generally, the larger the primary tumor the greater the amount of external irradiation delivered, with an appropriate reduction in the amount of intracavitary radium. Patients who had a positive lymphangiogram or a pre- or postirradiation hysterectomy or lymphadenectomy are not included in this analysis. All patients were followed for a minimum of 5 years. Local and regional failure rate in 193 patients receiving 4,000 rad whole pelvis irradiation plus radium was 1% and 4%, respectively, with a 3.1% incidence of severe complications. In 111 patients who received 5,000 rad whole pelvis irradiation plus radium, the local and regional failure rate was 3.5% and 4.5%, respectively, with a 10% incidence of severe complications. In patients who received 5,000 rad whole pelvis irradiation, complications were associated with unilateral parametrial boosts and with protruding vaginal sources. Of 21 patients who received 6,000 rad whole pelvis irradiation, three patients developed fistulae associated with high doses to the vagina delivered with protruding vaginal sources.

    Cervical cancer is the third most common cancer in women worldwide. The hypermethylation of P16, TSLC-1 and TSP-1 genes was analyzed in squamous cell carcinomas (SCC), cervical intraepithelial lesions (CIN) and adenocarcinomas (ADC) of the uterine cervix (total 181 lesions). Additionally human papillomavirus (HPV) type, EPB41L3, RASSF1 and RASSF2 hypermethylation were tested in ADC and the results were compared with those obtained previously by our group in SCC. P16, TSLC-1 and TSP-1 hypermethylation was more frequent in SCCs than in CINs. These percentages and the corresponding ones for EPB41L3, RASSF1 and RASSF2 genes were also higher in SCCs than in ADCs, except for P16. The presence of HPV in ADCs was lower than reported previously in SCC and CIN. Patients with RASSF1A hypermethylation showed significantly longer disease-free survival (P = 0.015) and overall survival periods (P = 0.009) in ADC patients. To our knowledge, this is the first description of the EPB41L3 and RASSF2 hypermethylation in ADCs. These results suggest that the involvement of DNA hypermethylation in cervical cancer varies depending on the histological type, which might contribute to explaining the different prognosis of patients with these types of tumors.

    The objectives of this study were to compare tumour staging and volume assessment by examination under anaesthesia (EUA), transrectal ultrasound (TRU) and magnetic resonance imaging (MRI) in patients with invasive carcinoma of the cervix, and to correlate findings with long-term outcome following treatment by radiotherapy. Tumour staging was performed on 60 patients immediately before starting radiotherapy. Clinicians and radiologists performing EUA, TRU or MRI were blinded to the results of other investigations. Tumour stage and dimensions were recorded prospectively for each technique, and analysed for concordance. The relationship between pre-treatment stage, size of tumour and patient outcome after radiotherapy was assessed, using clinical status 5 years after treatment as the truth measure. EUA, TRU and MRI assigned the same tumour stage in only 30% of patients and EUA and MRI agreed tumour stage in a further 27%. In cases of disagreement, the MRI stage correlated better with outcome than the TRU or EUA stage. There was a significant difference between tumour volume obtained from measurements made on MRI and those from TRU. 62% of patients with enlarged lymph nodes on pre-treatment MRI either died, or developed tumour recurrence or metastases. The ability of MRI to assess the full extent of bulky tumours and the presence of lymph node enlargement was an advantage over both EUA and TRU in identifying patients with a poor prognosis.

    The purpose of the study was to evaluate the prevalence of disordered gastrointestinal function following therapeutic irradiation. Gastrointestinal function was evaluated in 30 randomly selected patients who had received pelvic irradiation for treatment of carcinoma of the cervix between 1 and 6 years previously. Each patient underwent evaluations of (a) gastrointestinal symptoms (b) absorption of bile acid, vitamin B12, lactose and fat (c) gastrointestinal transit: gastric emptying, small intestinal transit and whole gut transit and (d) intestinal permeability. Results were compared with those obtained in 18 normal volunteers. Stool frequency was above the control range in five patients and had increased (p < 0.001) since radiotherapy treatment. Bile acid (p<0.001) vitamin B12(p<0.01) and lactose (p<0.01) absorption were less in the patients when compared with the control subjects. Bile acid adsorption was below the control range in 14 of the 30 patients. Dietary calcium intake was lower (p<0.05) in those patients with lactose malabsorption. Gastric emptying (p<0.01) and small intestinal transit (p<0.01) were more rapid in the patients. Both small intestinal (r=-0.39, p<0.05) and whole gut (r=-0.45) transit were inversely related to stool frequency. Either bowel frequency, bile acid adsorption, vitamin B12 absorption was outside the control range in 19 of the 30 patients. Abnormal gastrointestinal function is essentially an inevitable long-term sequel of pelvic irradiation. 41 refs., 4 figs., 3 tabs.

    Between January 1967 and December 1974, 254 patients with carcinoma of the uterine cervix were treated with either intracavitary radium and parametrial irradiation or 2000 rad whole pelvis irradiation followed by intracavitary radium and parametrial irradiation. In general, these patients had tumors of relatively limited volume and vaginal and uterine anatomy that was favorable for intracavitary radium. Not all patients had a lymphangiogram performed prior to irradiation. Of those who did, only patients with negative lymphangiograms are included in this analysis. All patient had a minimum follow-up of four years. The absolute four year survival rate for this group of patients was 86%. Only 6.3% of patients died of disease. The incidence of severe complications was 7.5%. Complications were associated with a high number of milligram hours of radium plus a high dose of external irradiation, in combination with either asymmetry of the radium system and/or history of previous pelvic inflammatory disease, pelvic surgery, or diverticulosis.

    Ninety-five squamocellular carcinomas of the uterine cervix, clinical Stages II and III, were treated by either four schedules combining 252-californium neutron-gamma-radiotherapy with different proportions of a neutron component (9, 6 and 3 Gy) or gamma-irradiation alone. Flow cytometric DNA profiles were obtainable in 72 cases before treatment and 56 cases were monitored for DNA content by flow cytometry (FCM) in weekly intervals by analysis of sequential microbiopsies for one month during and after radiotherapy. DNA aneuploidy was reduced from 40% (25/63) to 19% (9/47) one week within therapy in neutron-treated groups, but not after initial gamma-radiotherapy alone. Extinction of DNA aneuploid subpopulations occurred after neutron therapy in all remaining aneuploid tumors (9/9) during further monitoring, but only in 40% (2/5) of tumors after sole gamma-irradiation. In contrast, proliferation index by more than 50% was more often achieved in groups with a higher gamma-radiation component than after neutrons only. When all therapy-induced DNA flow cytometric events are taken together for evaluation of the effects of various radiotherapy schedules, it appears that the regimen with the maximal neutron dose may not be optimal for all tumors. It is hypothesized that the differences in the early flow cytometric DNA profiles may select the DNA aneuploid squamous cell uterine cervical carcinomas as candidates for combined neutron-brachytherapy, while highly proliferating DNA near-diploid tumors may profit more from treatment with a higher gamma-radiotherapy component. However, these early DNA flow cytometric findings need to be correlated with clinical course of the disease to validate this hypothesis, a process which will be completed at the end of the expected five-year clinical outcome in 2000.

    Since the introduction of the Papanicolaou smear and colposcopy, cervical cancers can be diagnosed and treated easily in their preinvasive state. Although theoretically cancer of the cervix should be detected and treated before becoming invasive disease, there are still too many women who develop invasive cancer of the cervix and require radical surgery and/or radiation therapy. The management of patients with recurrent or advanced disease is difficult and challenging.36 references.

    Abstract The aim of the present study is to identify the prognostic factors of overall survival and examine the effects of adjuvant chemotherapy and radiotherapy on the overall survival in neuroendocrine carcinoma of the uterine cervix (NECUC) patients. Forty-eight surgically treated patients were retrospectively recruited and clinicopathologic characteristics and treatments were reviewed. Kaplan–Meier product-limit method and Cox proportional-hazards regression were utilized for univariate and multivariate analyses. The median follow-up time was 20.6 months and the median overall survival was 30.7 months. The estimated 2-year and 5-year overall survival rates were 57.5% and 31.3%, respectively. Forty patients had ≤ stage IIA disease and 8 had >IIA disease. Univariate analysis identified the clinical stage ≤ IIA (P = 0.042), tumor size ≤ 4 cm (P = 0.005), negative lymph nodes metastasis (P < 0.001), depth of stromal invasion ≤ 1/2 (P = 0.001), negative parametrial involvement (P = 0.004), and weak staining of synaptophysin (P = 0.037), and chromogranin (P = 0.011) as the prognostic factors for an improved overall survival, while chemotherapy and radiotherapy were not prognostic factors in the whole cohort. However, surgery combined with chemotherapy and radiotherapy produced a survival advantage over surgery alone in patients with large tumors (P = 0.006). The combination of surgery and chemotherapy (with or without radiotherapy) did not show any significant difference in overall survival for small tumors (P = 0.816), compared with no chemotherapy (with or without radiotherapy). In addition, radiotherapy for tumors with squamous cell carcinoma or adenocarcinoma components achieved a better survival (P = 0.01), and there was a tendency of an unfavorable survival for radiotherapy in homogeneous carcinoma (P = 0.099). Tumor size was an independent prognostic factor in the multivariate analysis (HR: 12.724, 95% CI

    An asymptomatic 24-year-old woman underwent a colposcopy, cervical biopsy, and subsequently, a conization for a cervical squamous cell carcinoma in situ with glandular extension. Simultaneously, an endometrial biopsy was carried out in which, incidentally, a placental site nodule was diagnosed, a rare non-neoplastic lesion originating in the intermediate trophoblast. Given the coexistence of these two entities, it was necessary to make a differential diagnosis between them and also with other pathologies of the trophoblast such as an exaggerated placental site, placental site trophoblastic tumor, and epithelioid trophoblastic tumor.

    Between July 1981 and June 1983, 27 patients with advanced primary squamous cell carcinoma (SCC) of cervix and 8 with recurrent disease were treated using a pilot regimen of combination chemotherapy (CT): Mitomycin C (MIT), 5 Fluorouracil (5 FU), and radiation therapy (RT). CT and RT doses on this Phase I-II Study were escalated to the current regimen. A split course of RT was used, either pelvic RT alone or the same pelvic RT plus para-aortic RT. CT was given by continuous IV infusion days 1 through 4 of each half-course of RT. This was followed by one application of intrauterine /sup 137/Cs when possible. Three of the 8 patients with recurrence in the pelvis or para-aortic nodes had a complete response (CR) to CT-RT and are alive without disease at 19, 19 and 22 months after treatment, respectively. Twenty of the 27 (74%) primary patients had a CR. With a median duration of follow-up of 6 months 4/20 have relapsed, 1 in RT field, 2 at distant sites, and 1 in both. The acute toxicity of this regimen was tolerable: 2/35 developed transient leukopenia with one febrile episode, 9/35 developed transient thrombocytopenia without bleeding. Symptomatic sigmoid strictures developed in two patients, one requiring surgical intervention. Typically, near complete regression of tumor is noted on completion of the external RT, reproducing the dramatic responses that have been observed in SCC of the anal canal, esophagus and head and neck, with this CT-RT regimen.

    Late rectal and sigmoid toxicities seen in cervical cancer patients are attributed to brachytherapy despite rectal doses within tolerance limits. The purpose of this study was to identify additional dosimetric points which may better forecast rectal complications. Fifteen high dose rate intracavitary brachytherapy (ICA-HDR) applications with conventional X-ray and computed tomography (CT) based planning were studied. In addition to International Commission on Radiation Units and Measurement (ICRU) rectal and bladder points, proximal and distal rectal and sigmoid points were digitized on CT scans and dose volume histograms' (DVHs') parameters were computed and correlated. The mean ICRU, additional distal, proximal and sigmoid point doses were 486 ± 152 cGy, 527 ± 156 cGy, 401 ± 149 cGy and 838 ± 254 cGy, respectively, for a prescription of 700 cGy to point A. The mean sigmoid point dose was significantly higher than the ICRU rectal point doses (P=0.001). The high-dose sigmoid points were situated at a mean -8 mm (range -22.95 to 10.43 mm) lateral, 10 mm posterior (range -15.87 to 27.82 mm) and 31 mm (range 8.08-62.91 mm) cranial to the intracavitary applicator flange of central tandem. Our dosimetric study suggests that sigmoid points and 0.1 cm 3 receive significantly higher doses than rectal points during ICA-HDR in carcinoma of the uterine cervix. No definite conclusion on reproducible spatial distribution on orthogonal X-rays could be achieved. To document and reduce sigmoid doses, some form of 3D image-based planning is necessary.

    The present study was aimed to investigate the importance of Pin1 expression in Squamous Cell Carcinoma (SCC) of cervix and to assess its level with β-catenin and APC to understand the possible involvement of Pin1 in the regulation of these proteins and subsequent activation of Wnt/β-catenin signaling. Expression of Pin1, β-catenin and APC was examined in 153 SCC patients by immunohistochemistry and revalidated by western blotting. Of the 153 SCC analyzed, Pin1 was overexpressed in 73 (47.71%) cases. Loss of membranous β-catenin was noticed in 117 (76.47%) SCCs, whereas 66/153 (43.13%) and 93/153 (60.78%) cases showed its distinct cytoplasmic as well as nuclear accumulation respectively. Down regulation/loss of APC was observed in 69 (45.09%) cases, suggesting the activation of Wnt/β-catenin pathway in SCCs. Pin1 showed the significant association with nuclear β-catenin (r=.349, p<0.0001) and cytoplasmic loss of APC (r=-.287, p<0.0001). Both Pin1 as well as nuclear β-catenin were found to be associated with tumor stage (p=0.004, p=0.031) and tumor size (p=0.022, p=0.003). The Pin1 overexpression showed the significant association with disease free survival (p=0.002) but not with overall survival (p=0.421) of SCC patients. Current results explore the expressional relationship between Pin1, β-catenin and APC suggesting that Pin1 regulates the activation of Wnt/β-catenin pathway in SCCs via modulating the interaction between β-catenin and APC. Furthermore, the significant association of Pin1 and β-catenin with tumor variables underscores the clinical utility of these proteins in cervical cancer.

    A clinical treatment delivery platform has been developed and is being evaluated in a clinical pilot study for providing 3D controlled hyperthermia with catheter-based ultrasound applicators in conjunction with high dose rate (HDR) brachytherapy. Catheter-based ultrasound applicators are capable of 3D spatial control of heating in both angle and length of the devices, with enhanced radial penetration of heating compared to other hyperthermia technologies. Interstitial and endocavity ultrasound devices have been developed specifically for applying hyperthermia within HDR brachytherapy implants during radiation therapy in the treatment of cervix and prostate. A pilot study of the combination of catheter based ultrasound with HDR brachytherapy for locally advanced prostate and cervical cancer has been initiated, and preliminary results of the performance and heating distributions are reported herein. The treatment delivery platform consists of a 32 channel RF amplifier and a 48 channel thermocouple monitoring system. Controlling software can monitor and regulate frequency and power to each transducer section as required during the procedure. Interstitial applicators consist of multiple transducer sections of 2-4 cm length × 180 deg and 3-4 cm × 360 deg. heating patterns to be inserted in specific placed 13g implant catheters. The endocavity device, designed to be inserted within a 6 mm OD plastic tandem catheter within the cervix, consists of 2-3 transducers × dual 180 or 360 deg sectors. 3D temperature based treatment planning and optimization is dovetailed to the HDR optimization based planning to best configure and position the applicators within the catheters, and to determine optimal base power levels to each transducer section. To date we have treated eight cervix implants and six prostate implants. 100 % of treatments achieved a goal of >60 min duration, with therapeutic temperatures achieved in all cases.

    Background Chromosomal Comparative Genomic Hybridization (CGH) has been applied to all stages of cervical carcinoma progression, defining a specific pattern of chromosomal imbalances in this tumor. However, given its limited spatial resolution, chromosomal CGH has offered only general information regarding the possible genetic targets of DNA copy number changes. Methods In order to further define specific DNA copy number changes in cervical cancer, we analyzed 20 cervical samples (3 pre-malignant lesions, 10 invasive tumors, and 7 cell lines), using the GenoSensor microarray CGH system to define particular genetic targets that suffer copy number changes. Results The most common DNA gains detected by array CGH in the invasive samples were located at the RBP1-RBP2 (3q21-q22) genes, the sub-telomeric clone C84C11/T3 (5ptel), D5S23 (5p15.2) and the DAB2 gene (5p13) in 58.8% of the samples. The most common losses were found at the FHIT gene (3p14.2) in 47% of the samples, followed by deletions at D8S504 (8p23.3), CTDP1-SHGC- 145820 (18qtel), KIT (4q11-q12), D1S427-FAF1 (1p32.3), D9S325 (9qtel), EIF4E (eukaryotic translation initiation factor 4E, 4q24), RB1 (13q14), and DXS7132 (Xq12) present in 5/17 (29.4%) of the samples. Conclusion Our results confirm the presence of a specific pattern of chromosomal imbalances in cervical carcinoma and define specific targets that are suffering DNA copy number changes in this neoplasm.

    Background The link between squamous cell cervical carcinoma and HPV 16/18 is well-established but the magnitude of the risk association is uncertain and the importance of other high-risk HPV types unclear. Methods In two prospective nested case-control series among women participating in cytological screening in Sweden, we collected 2772 cervical smears from 515 women with cancer in situ (CIS), 315 with invasive squamous cell carcinoma (SCC), and individually matched controls. All smears were tested for HPV with PCR assays and the median follow-up until diagnosis was 5-7 years. Conditional logistic regression was used to estimate relative risks (RR) and 95% confidence intervals (CI). Results Presence of HPV16/18 in the first smear was associated with 8.5-fold (95% CI 5.3-13.7), and 18.6-fold (95% CI 9.0-38.9) increased risks of CIS and SCC, respectively, compared to women negative for HPV. Infection with other high-risk HPV types in the first smear was also associated with significantly increased risks for both CIS and SCC. Persistence of HPV16 infection conferred a RR of 18.5 (95% CI, 6.5-52.9) for CIS and 19.5 (95% CI 4.7-81.7) for SCC. The HPV16/18 attributable risk proportion was estimated to 30-50% of CIS, and 41-47% of SCC. Other high-risk HPV types also conferred significant proportions. Conclusions Our large population-based study provides quantification of risks for different HPV types and prospective evidence that non-16/18 high-risk HPV types increase the risk for future cervical cancer. Impact This study gives further insights into cervical cancer risk stratification with implications for HPV-based prevention strategies. PMID:20671136

    Glycosylation of proteins is altered in cancer cells and distinctive glycan structures are associated with specific cancers, but little is known about the complete glycan profile of particular tumors. In this study, glycomic analysis of squamous cell carcinoma (SCC) of the uterine cervix was performed to search for useful markers. A lectin microarray containing 45 lectins with different binding preferences that covered N- and O-linked glycans was coupled with evanescent field-activated fluorescent detection for glycomic analysis of SCC and normal squamous epithelium (NSE) of the cervix. Formalin-fixed, paraffin-embedded tissue specimens were obtained from 16 patients with uterine cervical cancer. Sections that included both tumor and non-tumor tissues were examined to detect alterations of glycans based on the lectin-binding pattern. Hippeastrum hybrid lectin was found to be a sensitive marker for distinguishing SCC of the cervix from NSE. It was the best lectin for discriminating SCC from other tissues according to receiver-operator curve analysis, as it showed a high sensitivity (81.8%), a high specificity (70.1%), and a large area under the curve (0.8182). Histochemistry confirmed specific cytoplasmic staining of SCC cells by Hippeastrum hybrid lectin, while there was little staining of cervical intraepithelial neoplasia and no staining of NSE. The present lectin microarray technique could be applied for tissue-based glycomic analysis of various tumors and for discovery of glycan-related biomarkers. © 2017 Japan Society of Obstetrics and Gynecology.

    Objective To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. Methods The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. Results The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). Conclusion Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC. PMID:28028992

    Patients with small recurrent cervical carcinomas following radiation therapy may be salvaged with radical hysterectomy rather than exenteration. Between 1953 and 1993, 50 patients underwent radical hysterectomy for persistent (n = 18) or recurrent (n = 32) cervical cancer after primary radiotherapy. The mean age of the cohort was 44 years (range, 23-70). Histologic types were squamous in 46, adenocarcinoma in 3, and adenosquamous in 1. Of 37 patients with staged disease, 24 had stage IB/IIA, 7 had stage IIB, 2 had stage IIIA, and 2 had stage IIIB. Combination radiotherapy, consisting of 40-45 Gy external-beam radiation plus brachytherapy (mean 6980 mg/hr), was performed in 32 patients (64%). In the 32 patients with recurrent lesions, the median interval from definitive radiotherapy to radical hysterectomy was 16 months (4-301), with 19 of these patients (60%) presenting within the first 24 months. Patients with persistent carcinomas underwent radical hysterectomy after a median observation interval of 2 months (1-4). A class II or III radical hysterectomy was performed in 39 (78%) cases. Pelvic and para-aortic lymph node samplings were performed in 39 patients (78%), including 33 (66%) who underwent complete pelvic lymphadenectomy. Among those sampled, 5 (13%) had metastatic nodal disease. All 5 patients died of disease at a median 13 months after surgery. Severe postoperative complications occurred in 21 patients (42%). The most common site of injury was the urinary tract, with 14 patients (28%) developing vesicovaginal or rectovaginal fistulae, 11 (22%) developing ureteral injuries, and 10 (20%) developing severe long-term bladder dysfunction. There was one postoperative death from sepsis among the entire population. Patients with abnormal preoperative intravenous pyelograms (P < 0.05), patients with recurrent presurgical lesions (P < 0.05), and patients with postoperative pelvic cellulitis (P < 0.01) were more likely to develop fistulae.

    Thanks to the growing knowledge on biological behaviors of hepatocellular carcinomas (HCC), as well as continuous improvement in imaging techniques and experienced interpretation of imaging features of the nodules in cirrhotic liver, the detection and characterization of HCC has improved in the past decade. A number of practice guidelines for imaging diagnosis have been developed to reduce interpretation variability and standardize management of HCC, and they are constantly updated with advances in imaging techniques and evidence based data from clinical series. In this article, we strive to review the imaging techniques and the characteristic features of hepatocellular carcinoma associated with cirrhotic liver, with emphasis on the diagnostic value of advanced magnetic resonance imaging (MRI) techniques and utilization of hepatocyte-specific MRI contrast agents. We also briefly describe the concept of liver imaging reporting and data systems and discuss the consensus and controversy of major practice guidelines.

    To evaluate disease outcomes and toxicity in cervical cancer patients treated with pelvic intensity-modulated radiation therapy (IMRT). We included all patients with Stage I-IVA cervical carcinoma treated with IMRT at three different institutions from 2000-2007. Patients treated with extended field or conventional techniques were excluded. Intensity-modulated radiation therapy plans were designed to deliver 45 Gy in 1.8-Gy daily fractions to the planning target volume while minimizing dose to the bowel, bladder, and rectum. Toxicity was graded according to the Radiation Therapy Oncology Group system. Overall survival and disease-free survival were estimated by use of the Kaplan-Meier method. Pelvic failure, distant failure, and late toxicity were estimated by use of cumulative incidence functions. The study included 111 patients. Of these, 22 were treated with postoperative IMRT, 8 with IMRT followed by intracavitary brachytherapy and adjuvant hysterectomy, and 81 with IMRT followed by planned intracavitary brachytherapy. Of the patients, 63 had Stage I-IIA disease and 48 had Stage IIB-IVA disease. The median follow-up time was 27 months. The 3-year overall survival rate and the disease-free survival rate were 78% (95% confidence interval [CI], 68-88%) and 69% (95% CI, 59-81%), respectively. The 3-year pelvic failure rate and the distant failure rate were 14% (95% CI, 6-22%) and 17% (95% CI, 8-25%), respectively. Estimates of acute and late Grade 3 toxicity or higher were 2% (95% CI, 0-7%) and 7% (95% CI, 2-13%), respectively. Intensity-modulated radiation therapy is associated with low toxicity and favorable outcomes, supporting its safety and efficacy for cervical cancer. Prospective clinical trials are needed to evaluate the comparative efficacy of IMRT vs. conventional techniques. Copyright © 2011 Elsevier Inc. All rights reserved.

    Extended-field irradiation offers a significant chance of cure for patients with para-aortic node metastases if pelvic disease can be controlled. Prognosis is best for patients with microscopic para-aortic disease or with a single enlarged node. Complications of extended-field irradiation can be minimized with careful radiation therapy technique that uses multiple fields and high-energy beams of 18 MV or greater and by avoiding transperitoneal surgical staging. Although the role of prophylactic para-aortic irradiation is still being defined, randomized trials suggest that extended fields do benefit some patients with locoregionally advanced disease.

Methods and Materials: From 1996 to 2005, a total of 378 patients with LACC (International Federation of Gynecology and Obstetrics Stage IB2-IVA) were treated with RHT. External beam radiotherapy (RT) was applied to 46-50.4 Gy and combined with brachytherapy. The hyperthermia (HT) was prescribed once weekly. Primary end points were complete response (CR) and local control. Secondary end points were overall survival, disease-specific survival, and late toxicity. Patient, tumor, and treatment characteristics predictive for the end points were identified in univariate and multivariate analyses. Results: Overall, a CR was achieved in 77% of patients. At 5 years, local control, disease-specific survival, and incidence of late toxicity Common Terminology Criteria for Adverse Events Grade 3 or higher were 53%, 47%, and 12%, respectively. In multivariate analysis, number of HT treatments emerged as a predictor of outcome in addition to commonly identified prognostic factors. Conclusions: The CR, local control, and survival rates are similar to previously observed results of RHT in the randomized Dutch Deep Hyperthermia Trial. Reported treatment results for currently applied combined treatment modalities (i.e., RT with chemotherapy and/or HT) do not permit definite conclusions about which combination is superior. The present results confirm previously shown beneficial effects from adding HT to RT and justify the application of RHT as first-line treatment in patients with LACC as an alternative to chemoradiation.

    A prospective randomized study in selected patients with Stage IB and IIA carcinoma of the uterine cervix was carried out. Patients were randomized to be treated with 1) irradiation alone consisting of 1000 rad whole pelvis, additional 4000 rads to the parametria with a step wedge midline block, and two intracavitary insertions for 7500 mgh; and 2) irradiation and surgery, consisting of 2000 rad whole pelvis irradiation, one intracavitary insertion for 5000 to 6000 mgh followed in two to six weeks later by a radical hysterectomy with pelvic lymphadenectomy. The five-year, tumor-free actuarial survival for Stage IB patients treated with radiation was 87% and with preoperative radiation and surgery 82%. In Stage IIA, the actuarial five-year survival NED was 57% for the irradiation alone group and 71% for the patients treated with preoperative radiation and radical hysterectomy. Major complications of therapy were slightly higher in the patients trated with radiation alone (9.4%, consisting of one recto-vaginal fistula and one vesico-vaginal fistula and a combined recto-vesico-vaginal fistula in another patient). In the preoperative radiation group, only two ureteral strictures (4.1%) were noted. The present study shows no significant difference in therapeutic results or morbidity for invasive carcinoma of the uterine cervix Stage IB or IIA treated with irradiation alone or combined with a radical hysterectomy.

    An evaluation of rectal, rectosigmoidal, and bladder doses from intracavitary brachytherapy in carcinoma of the cervix has been initiated on a routine basis in an effort to obtain the optimum radiotherapeutic dose. Contrast radiography on a radiotherapy simulator is used to image the rectum and bladder, and dose rates are determined at predesignated reference points with the aid of computer calculated dose distributions. Forty-three patients have been reviewed in order to ascertain the correlation between radiation injury and dose at reference points in the rectum and bladder. In a related study involving 77 patients, the doses at points A and B and the prescription in mghr were analyzed in relation to radiation injury. There was no apparent association between the incidence of radiation injury in either the mghr prescription or the doses at points A or B. Computer calculations were supplemented with in vivo and in vitro thermoluminescent dosimeter (TLD) measurements. We conclude that routine contrast radiography of the rectum and the bladder with dose calculations at selected reference points provides important information for optimizing radiotherapy in carcinoma of the cervix without a significant increase in treatment planning effort or patient discomfort.

    Thyroid nodules are encountered in clinical practice during the diagnostic procedures or patients' follow-up due to other diseases quite far from the thyroid gland with prevalence 4-50% in general population, depending on age, diagnostic method and race. The prevalence of thyroid nodules increases with age and their clarification should be done for their adequate treatment. An 18F-FDG PET/CT was done with a PET/CT scanner (Philips Gemini TF), consisting of dedicated lutetium orthosilicate full ring PET scanner and 16 slice CT. The PET/CT scan of the whole-body revealed on the CT portion a hypodense nodular lesion in the left lobe of the thyroid gland with increased uptake of 18F-FDG on the PET with SUVmax 10.3 and demonstrated a complete response to the induction therapy of the main oncological disease of the patient--squamous cell carcinoma. This clinical case demonstrates that whole-body 18F-FDG-PET/CT has an increasingly important role in the early evaluation of thyroid cancer as a second independent malignant localization. Focal thyroid lesion with high risk of thyroid malignancy was incidentally found on 18F-FDG PET/CT.

    Background: Cisplatin is widely used as radio sensitizer in head and neck cancer (HNC) and carcinoma cervix (CaCx). This study aims to see comparative nephrotoxicity of cisplatin in HNC and in CaCx without obstructive uropathy treated by concurrent chemoradiotherapy (CCRT). Materials and Methods: Fifty patients of HNC and 50 patients of CaCx stage II/III without obstructive uropathy were included in this study. Cisplatin 50 mg intravenous weekly was given before EBRT with adequate hydration and premedication in both groups. Before chemotherapy; blood urea, serum creatinine, and glomerular filtration rate (GFR) were measured. GFR was measured using 99mTc diethylene triamine pentacaetic acid (DTPA) renogram study. Results: At the end of 4th week, blood urea level 41-45 mg% was in 40 and 4% in HNC and CaCx, respectively (P = 0.018). At the end of 3rd and 4th week, blood urea level >45 mg% was 10 and 6% in HNC cases, respectively. At the end of 4th week, serum creatinine level 1.1-1.5 mg% was 50 and 8% in HNC and CaCx, respectively (P = 0.047). Serum creatinine level >1.5 mg% was 6, 8, and 22% in HNC at the end of 2nd, 3rd, and 4th week, respectively. GFR <80 ml/min at the end of 4th week was 14% in HNC and only 2% in CaCx. GFR <100ml/min was significant at the end of 4th week (P = 0.04). Univariate analysis showed significant relation between reduced oral fluid intake and reduced GFR (P < 0.001). Conclusion: In HNC, during concurrent chemoradiation, as the 3rd-4th week is reached, oral mucosal reactions increase and affect oral intake which further add to the cisplatin-induced nephrotoxicity. In CaCx without obstructive uropathy, renal function impairment is less severe as oral intake of water and liquid is not much impaired. PMID:25422808

    Advanced basal cell carcinomas are a subset of basal cell carcinomas that can be difficult to treat either due to their local invasiveness, proximity to vital structures, or metastasis. The incidence of all basal cell carcinoma is increasing in the United States, although it is not known whether advanced basal cell carcinomas (aBCCs) are also increasing. Recently, highly targeted therapy based on knowledge of the basal cell carcinoma pathogenesis has become available either commercially or through human clinical trials. These orally available drugs inhibit the Hedgehog signaling pathway, and lead to advanced basal cell carcinoma shrinkage that can enable preservation of adjacent vital organs. In this review, we outline the role of Hedgehog pathway inhibitors as well as other treatment modalities such as excision, radiotherapy and more traditional chemotherapy in treating advanced basal cell carcinomas. We also highlight current gaps in knowledge regarding the use and side effects of this targeted therapy.

    Hepatocellular carcinoma (HCC) is a significant cause of death worldwide. HCC is a highly vascular tumor, and proangiogenic cytokines such as vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and fibroblast growth factor may play crucial roles in this disease. Sorafenib, a multikinase inhibitor that blocks VEGF and PDGF signaling, was the first systemic therapy to demonstrate improved survival in patients with advanced HCC. Several other drugs targeting VEGF are in development. Because of the anticipation of eventual resistance to anti-VEGF therapies, drugs that also target alternative proangiogenic pathways are being investigated. Recent clinical and preclinical data along with ongoing studies are reviewed. PMID:23576483

    Basal cell carcinomas (BCCs) are very common epithelial cancers that depend on the Hedgehog pathway for tumor growth. Traditional therapies such as surgical excision are effective for most patients with sporadic BCC; however, better treatment options are needed for cosmetically sensitive or advanced and metastatic BCC. The first approved Hedgehog antagonist targeting the membrane receptor Smoothened, vismodegib, shows remarkable effectiveness on both syndromic and nonsyndromic BCCs. However, drug-resistant tumors frequently develop, illustrating the need for the development of next-generation Hedgehog antagonists targeting pathway components downstream from Smoothened. In this article, we will summarize available BCC treatment options and discuss the development of next-generation antagonists.

    Objective: To investigate the expression of microRNA (miRNA, miR) let-7e-3p in different cervical lesions and its clinical significance. Methods: The expression of miR-let-7e-3p in the tissues of normal cervix (n=26), high-grade squamous intraepithelial lesion (HSIL) (n=37), and cervix carcinoma (n=101) were detected by reverse transcription and quantitative polymerase chain reaction (RT-qPCR). The correlation of miR-let-7e-3p expression with the clinicopathological parameters of patients with cervical cancer was analyzed. miR-let-7e-3p mimic was transfected into cervical carcinoma Siha cells. The cell cycle and apoptosis were determined by flow cytometry; cell proliferation was determined by CCK-8 kit; and the migration and invasion of cells were determined by Transwell assay. Results: The relative expression levels of miR-let-7e-3p in normal cervix, HSIL, and cervical carcinoma were 1.45±0.24, 0.79±0.05 and 0.46±0.04, respectively (all P<0.05). After transfection with miR-let-7e-3p mimic, the S-phase fraction and apoptosis rate of Siha cells were increased significantly compared with control group[(29.76±6.6)% vs (13.38±1.3)%, P<0.05; (5.98±1.38)% vs (3.53±0.79)%, P<0.05, respectively]. OD of transfected Siha cells at 48, 72 and 96 h were 0.57±0.11,0.65±0.04 and 0.84±0.14, which were significantly lower than those of untransfected Siha cells (0.74±0.05, 0.93±0.10 and 1.47±0.14, all P<0.05). The migration and invasion abilities of transfected Siha cells were not significantly changed (all P>0.05). Conclusion: The expression of miR-let-7e-3p is down-regulated in cervical neoplasms, which is associated with cell cycle arrest and proliferation inhibition of cervical cancer cells.

    To investigate the dosimetric influence of filtered and flattening filter free (FFF) photon beam of 6 and 10 MV energies on cervix RA radiotherapy planning and to find possibilities to develop the clinically acceptable RA plans with FFFB photon beam and explore their potential benefits to cervix cancer patients. FFF photon beams enhances the treatment delivery by increased dose rate which results in shorter treatment time, this shorter treatment time reduces intrafraction motion and enhance comfort to the patients. RA plans were generated for filtered and flattening filter free photon beams of 6 and 10 MV energies using same dose-volumes constraints. RA plans were generated to deliver a dose of 50.4 Gy in 28 fractions, for a cohort of eleven patients reported with cervix carcinoma. RA plans were evaluated in terms of PTV coverage, dose to OAR's, CI, HI, total no. of monitor units (MUs) and NTID and low dose volume of normal tissues. Clinically acceptable and similar plans were generated for filtered and flattening filter free photon beams. FFFB delivered slightly higher mean target dose (52.28 Gy vs. 52.0 Gy, p = 0.000 for 6 MV and 52.42 Gy vs. 52.0 Gy, p = 0.000 for 10 MV) less homogeneous (1.062 vs. 1.052, p = 0.000 for 6 MV and 1.066 vs. 1.051, p = 0.000 for 10 MV) and less conformal (1.007 vs. 1.004, p = 0.104 for 6 MV and 1.012 vs. 1.003, p = 0.010 for 10 MV) RA plans compared to FB. FFFB delivered more doses to the bladder and rectum, also required more numbers of MUs in comparison to FB. This study concludes that FB is more beneficial for cervix RA planning in comparison to FFFB, as FB generates more conformal and homogenous rapid arc plans and offers better OAR's sparing.

    This is an analysis of 123 patients with Stage IB-IIA-B carcinoma of the intact uterine cervix, 6 cm or greater in diameter, who were treated with curative intent at the University of Florida with radiation alone or radiation followed by a hysterectomy between October 1964 and February 1982. There is a minimum follow-up of 2 years in all patients; 87% of all recurrences and 91% of pelvic recurrences occurred within this time period. Examination of pelvic control rates, as well as disease-free survival, showed no significant advantage in pelvic control, disease-free survival, or absolute survival for either treatment group when compared by stage and tumor size. The incidence of severe complications was 6% for patients treated with irradiation alone and 15% for those treated with irradiation and surgery.

    Forty-two women with "bulky" squamous cell carcinoma of the uterine cervix, larger than 5 cm, were treated between 1982 and 1988. The median follow-up was 5 years (from 37 to 106 months). The age range was from 25 to 77 years (mean: 49). There were 14 stage Ib, 5 stage IIa, and 23 stage IIb operable patients. Forty grays were delivered at mid-plane of the pelvis (23 fractions in 31 days) using the four-field technique (6-18 MV). External beam radiation therapy was followed by 20 Gy of intracavitary radiation therapy. Forty-eight days later total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH-BSO) and bilateral pelvic lymphadenectomy were performed. The 3- and 5-year disease-free survival was 83 and 81%, respectively. The 5-year locoregional control rate was 83%. Thirteen patients suffered from mild to severe complications (31%) but there were only two long-term (5%) complications.

    The combination of surgery and radiotherapy for early cases of cancer of the cervix has been accused of producing prohibitive complication rates. In a series of 612 patients with cancer of the cervix, Stage IB, the frequency of major complications from the urinary and gastrointestinal tract has been studied, and an attempt has been made in determining the most probable etiology of these complications. No significant increase in complications can be attributed to the use of preoperative intracavitary irradiation. In patients with pelvic lymph node metastases the combination of radical surgery and a full course of radiotherapy is associated with a high complication risk, as 12% of these patients developed major complications. Their 5-year survival, however, was high: 54%.

    Carcinoma of the bilharzial bladder, the most common cancer in Egyptian patients has been, until recently, largely treated by surgery. We have studied the activity of a series of single agents in phase II trials and identified a number of active agents. Here we report the results of a trial in which therapeutic combinations of the most active agents were administered in alternating cycles to patients who had never received chemotherapy. The study included 30 patients with histologically proven inoperable (20), recurrent (5, 2 of whom subsequently developed metastases), or metastatic disease (5). There were 27 males and 3 females, with a median age of 48.5 years (range 29-65 years). Fourteen patients had squamous cell carcinoma, 12 had transitional cell carcinoma, 2 had adenocarcinoma, and the remaining 2 had undifferentiated carcinoma. Chemotherapy consisted of epidoxorubicin (120 mg/sqm i.v. d1) and vincristine (1.4 mg/sqm i.v., days 1 and 8) alternating with etoposide (100 mg/sqm i.v. infusion over 1 hour, days 1 to 5) and ifosfamide (1800 mg/sqm i.v. infusion over 2 hours, days 1 to 5). Mesna was given as a uroprotector at 40% of the ifosfamide dose at 0, 4, and 8 hours after the ifosfamide infusion. Courses were repeated every 3-4 weeks. Among the 22 evaluable patients, 8 (36.5%) had a partial and one (4.5%), a complete response, giving a response rate of 46%. Three more patients had responses that were less than a partial remission, and 6 patients showed disease stabilisation on chemotherapy. Toxicities were tolerable and consisted mainly of myelosuppression. Results were further analysed in relation to pathologic subtype, disease status at the start of chemotherapy, and the delivered dose intensity. No relationship was found between any of these parameters and response to therapy. Advanced bilharzial bladder cancer is relatively sensitive to combination chemotherapy, but complete remission and prolonged survival is rare in this subgroup of patients with

    Purpose: Aim of this study is to determine the dosimetric influence of Filtered and Flatting Filter Free Photon Beam of 10 MV energy on RA planning for Ca. Cervix. Methods: CT data sets of eleven patients reported with carcinoma cervix were used for RA planning for 10MV -FFB and 10MV-FFFB. RA plans were generated using two full arcs.All RA plans were generated to deliver a dose of 50.4Gy in 28 fractions for PTV and ALARA for OAR’s. All plans were analysed for PTV Coverage, conformity Index, homogeneity index, dose to OAR’s, integral dose to normal tissue and total monitor units were studied. Results: DVH was used to evaluate RA plans for both 10MV-FFB and 10MV-FFFB photon beam. Planning results show a comparable PTV coverage for both energies. Results shows volume of PTV receiving prescription dose were 95.10+ 0.09% and 95.09 +0.11%, and volume of PTV receiving a dose of 107% is 0.45+0.96% and 5.25+8.9%, homogeneity index (HI) were 1.051+0.007 and 1.066+0.008, Conformity Index(CI) were 1.003+0.019 and 1.012+0.013, Mean Integral dose were 2.65+0.34 and 2.60+0.33(*10−5Gy.cm3) for 10MV-FFB and 10MV-FFFB respectively. 10MV-FB shows statistically significant (p<0.05) improvement in mean doses to bladder, rectum, bowel and mean total number of MU’s and also shows remarkable decrease in mean total no. of MU’s by 43.7% in comparison to 10MV-FFFB. There is statistically significant (p<0.05) difference found in CI and HI for 10MV-FB in comparison to 10MV -FFF beam. 10MV-FFFB shows statistically significant (p<0.05) for mean NTID and delivers 1.65 % less NTID in comparison to 10 MV- FB. Conclusion: 10MV-FB is superior to 10MV-FFFB for rapid arc planning in case of Cervix carcinomas, it offers better target coverage and OAR’s sparing, comparable mean Integral dose to normal tissues and 10 MV- FB also produced highly conformal and homogeneous dose distribution in comparison to 10MV-FFFB.

    The efficacy of concurrent chemoradiotherapy (CTRT) in locally advanced cervix cancer (LACC, stages IIB-IVA) is contentious. This is due to the variable extent of therapeutic benefit reported in different randomized clinical trials and meta-analyses that usually include all stages of cervix cancer. A systematic review and meta-analysis was therefore conducted to evaluate the efficacy of concurrent CTRT over radiotherapy (RT) alone, predominantly in LACC for the key endpoints; complete response (CR), long-term loco-regional control (LRC), overall survival (OS), grade III/IV acute and late toxicities. Six databases namely - PubMed, EMBASE, SCOPUS, Web of Science, Google Scholar and Cochrane library were explored and supplemented by hand-searching. Only prospective randomized trials conducted in LACC between concurrent CTRT and RT alone with no surgical interventions were included. Fourteen English language articles from 1788 citations were shortlisted for the final analysis. Of the 2445 patients evaluated (CTRT: n=1217; RT: n=1228), 95.7% had LACC and 96% had a squamous cell histology. Eight studies used cisplatin alone, 4 had cisplatin-based combination chemotherapy (CT) while 2 used mitomycin-C, either alone or in combination. CTRT improved the CR (+10.2%, p=0.027), LRC (+8.4%, p<0.001) and OS (+7.5%, p<0.001) over RT alone. However a 10.4% higher incidence of grade III/IV acute toxicities (p<0.001) was also evident with CTRT. Late toxicities in both groups were equivalent. Subgroup analysis and meta-regression did not reveal any significant advantage in outcomes between the 3 CTRT regimens. Thus, although concurrent CTRT provides conclusive therapeutic benefit over RT alone in LACC, the choice of CT agents should be based on their cost-effectiveness and the anticipated expenses for the management of any associated acute toxicities. This assumes importance particularly in resource-constrained low-middle-income countries with the highest burden of LACC, where

    US and MRI currently are the best imaging modalities to evaluate pathology of the uterine cervix and vagina. Carcinoma of the cervix is the most frequent indication for imaging. MRI allows preoperative staging of cervical carcinoma based on FIGO classification, and post treatment follow-up. Other uterine cervix diseases are less frequently imaged and include a wide range of entities that most frequently cause increased T2W signal at MR imaging. Pathology of the pelvic floor, vagina, vulva, and perineum also includes a wide range of entities that have seldom been described in the imaging literature.

    Between February 1979 and January 1982, a Phase II study of misonidazole as a radiosensitizer was performed in 34 patients with advanced carcinoma of the uterine cervix. Twenty-nine patients were treated with conventional fractionated radiation and five patients with a twice daily fractionation schedule, 3 days a week. The total dose to the whole pelvis was 5000 cGy delivered in 5.5 weeks. Intracavitary curietherapy delivered an additional boost to the tumor. Misonidazole was given to all patients during external radiation and to 25 patients during intracavitary treatment for a total dose of 11 to 14 g/mS. All patients were followed for at least 28 months after treatment with a median follow-up of 52 months. Misonidazole toxicity included peripheral neuropathy (18%) and central nervous system toxicity (3%). The 3-year survival rate is 74% and the 3-year disease-free survival is 57%. When compared to our historical group survival, 42 and 12% for Stage III and IV, respectively, our data suggest that there is a probable advantage from using misonidazole in advanced carcinoma of the cervix.

    Purpose/Objective: To analyze the details of brachytherapy practice in patients treated for carcinoma of the cervix in the United States between 1996 and 1999. Methods and Materials: Radiation facilities were selected from a stratified random sample. Patients were randomly selected from lists of eligible patients treated at each facility. A total of 442 patients' records were reviewed in 59 facilities to obtain data about patients' characteristics, evaluation, tumor extent, and treatment. National estimates were made using weights that reflected the relative contribution of each institution and of each patient within the sampled institutions. From our survey we estimate that 16,375 patients were treated in the United States during this study period. Unless otherwise specified, brachytherapy practice was based on the 408 patients who had their brachytherapy or all their treatment at the surveyed facility. Results: A total of 91.5% of patients underwent brachytherapy at the initial treating institution; 8.5% were referred to a second site for brachytherapy. Forty-two percent of U.S. facilities referred at least some patients to a second facility for brachytherapy. Of U.S. facilities that treated {<=}2 eligible patients per year, 61% referred all of their patients to a second facility for brachytherapy or treated with external RT alone; none of the U.S. facilities with larger experience (>2 eligible patients per year) referred all their patients to a second facility for brachytherapy treatment, but 28% referred some patients to an outside facility for brachytherapy. Overall, 94% of patients who completed treatment with curative intent received brachytherapy. Of these patients who had brachytherapy, 77.8%, 13.3%, and 0.9%, respectively, were treated with low-dose-rate (LDR), high-dose-rate (HDR), or a combination of HDR and LDR brachytherapy; 7.9% had interstitial brachytherapy (5.7% LDR and 1.9% HDR, 0.3% mixed). In facilities that treated >2 patients per year, 15

    Nasopharyngeal cancer (NPC) is a tumor of epidermoid origin with an entirely different biological behavior than other carcinoma of the head and neck region. A retrospective analysis was performed in 93 cases with locally advanced NPC treated with induction chemotherapy followed by radiation therapy (RT; 79 patients) or concomitant RT and chemotherapy. Totally 66 patients (71%) achieved a complete response (CR), 68% of the patients treated with induction chemotherapy followed by RT, 86% with concomitant chemoradiotherapy. After a median follow-up of 5.5 years 28 out of these 66 relapsed, 25 of them locoregionally. Median time to progression was 22.5 months, median overall survival (OS) 45 months, 5-year actuarial survival was 41.5%. Age, T and N classification, histological type and type of chemotherapy were independent significant factors for OS. Combined chemotherapy and RT in patients with locally advanced NPC result in a high CR rate. The main problem remains the locoregional control. Randomized studies are needed in order to define the optimal use of chemotherapy in combination with RT.

    Cervical cancer is one of the most common neoplastic diseases affecting women, with a worldwide incidence of almost half a million cases. A history of smoking and use of oral contraceptives have been confirmed to be risk factors for cervical cancer. Genetic susceptibility and immune response, especially impaired cellular immune response, may well be related to the development of cervical cancer. NBS1 is one of the key proteins participating in the recognition and repair of double-strand breaks that may lead to genomic instability and cancer if unrepaired. The objective of the present study was therefore to investigate NBS1 Glu185Gln gene polymorphisms and the risk of cervix cancer in a northern Indian population. We found that passive smokers having particular NBS1 genotypes (Glu/Gln, Gln/Gln or Glu/Gln + Gln/Gln)have an increased risk of developing cervix cancer (OR 5.21, p=0.000001; OR 4.60, p=0.001; OR 5.10, p=0.0000009, respectively).The risk was increased 2.4-fold in oral contraceptive users with a Glu/Gln genotype. We conclude that the risk of cervical cancer is increased in passive smokers and in users of oral contraceptives with certain NBS1 genotypes.

    Purpose: The objective of this work is to evaluate and compare Large field IMRT and RapidArc planning for Carcinoma Cervix and Para-aotic node irradiation. Methods: In this study, ten patients of Cervix with para-aotic node have been selected with PTV length 35+2cm. All plans were generated in Eclipse TPS V10.0 with Dynamic IMRT and RapidArc technique using 6MV photon energy. In IMRT planning, 7 fields were chosen to get optimal plan and in RapidArc, double Full arc clockwise and counter clockwise were used for planning. All the plans were generated with single isocenter and calculated using AAA dose algorithm. For all the cases the prescribed dose to PTV was same and the plan acceptance criteria is; 95% of the PTV volume should receive 100% prescribed dose. The tolerance doses for the OAR’s is also taken in to account. The evaluation criteria used for analysis are; 1) Homogeneity Index, 2) Conformity Index, 3) Mean Dose to OAR’s, 4)Total monitor units delivered. Results: DVH analysis were performed for both IMRT and RapidArc planning. In both the plans, 95% of PTV volume receives prescribed dose and maximum dose are less than 107%. The conformity index are same in both the techniques. The mean Homogeneity index are 1.036 and 1.053 for IMRT and RapidArc plan. The mean (mean + SD) dose of bladder and rectum in IMRT is 44.2+1.55, 42.05+2.52 and RapidArc is 46.66+1.6, 44.2+2.75 respectively. There is no significant difference found in Right Femoral head, Left Femoral head and Kidney doses. It is found that total MU’s are more in IMRT compared with RapidArc planning. Conclusion: In the case of cervix with Para-arotic node single isocenter irradiation, IMRT planning in large-field is better compared to RapidArc planning in terms of Homogeneity Index and mean dose of Bladder and Rectum.

  13. A new case of primary signet-ring cell carcinoma of the cervix with prominent endometrial and myometrial involvement: Immunohistochemical and molecular studies and review of the literature

    2012-01-01

    Background As a rule, endocervical tumours with signet-ring cell are classed as metastatic extra-genital neoplasms. In a patient aged 45 years, we describe primary cervical signet-ring cell carcinoma (PCSRCC) characterized by prominent endometrial and myometrial involvement, simulating primary endometrial adenocarcinoma with cervical extension. In addition, a review was made of the literature to identify the clinical and pathological features of this rare malignancy. Case presentation A 45-year-old woman was referred to our Gynaecology Department due to persistent abnormal vaginal bleeding. Transvaginal ultrasonography showed slight endometrial irregularities in the whole uterine cavity suggestive of endometrial neoplasms. Pelvic magnetic resonance imaging revealed diffuse enlargement of the cervix, which had been replaced by a mass. Induration extended to the parametria and sigmoid colon fat. Histological examination of endometrial curettage and a cervical biopsy revealed a neoplasm characterized by neoplastic signet-ring cells and trabecular structures. Immunohistochemical analysis and molecular studies showed certain findings consistent with a cervical neoplasm, such as positivity to CEA, keratin 7, Ca-125 and p16 and the presence of HPV (Human Papilloma Virus) DNA 18. On examination of the hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy, the lesion replacing the cervix, endometrium and myometrium, revealed the same immunohistochemical findings observed on endometrial curettage and cervical biopsy specimens. Metastases were found in an ovarian cystic lesion and the lymph nodes. Conclusion With this report the authors have demonstrated that the spread of cervical adenocarcinoma to the uterine corpus, although rare, may be observed, and that in this instance immunohistochemical and molecular studies can provide sufficient information for accurate diagnosis even on small biopsy specimens.

    It is not known whether radiotherapy or surgery is better as initial treatment for locally advanced mucinous adenocarcinoma of the uterine cervix. We reviewed the medical records and pathological materials of 32 patients with International Federation of Gynecology and Obstetrics stage IB2-IIB mucinous adenocarcinoma, who had undergone radiotherapy or radical hysterectomy as primary treatment between 2001 and 2010. p16(INK4a) immunohistochemistry was performed as a marker for human papillomavirus-related adenocarcinoma. Thirteen patients received radiotherapy and 19 patients underwent radical hysterectomy. The cumulative 3-year locoregional control rates in the radical hysterectomy and radiotherapy groups were 79.0 and 46.2 % (P = 0.03), and 5-year overall survival rates were 70.7 and 38.5 % (P = 0.09), respectively. Of patients with p16(INK4a)-positive tumors (n = 19), the cumulative 3-year locoregional control rates in the radical hysterectomy and radiotherapy groups were 100 and 60.0 % (P = 0.01), and 5-year overall survival rates were 88.9 and 40.0 % (P = 0.04), respectively. Conversely, the cumulative 3-year locoregional control rates in the human papillomavirus-negative radical hysterectomy group and radiotherapy group were 20.0 and 37.5 % (P = 0.66), and 5-year overall survival rates were 20.0 and 37.5 % (P = 0.60), respectively. Radical hysterectomy may significantly improve locoregional control and overall survival compared with radiotherapy for stage IB2-IIB mucinous adenocarcinoma patients, especially those with p16(INK4a)-positive mucinous adenocarcinoma.

    Background Metastatic and recurrent, platinum resistant cervix cancer has an extremely poor prognosis. The Gynecologic Oncology Group has studied >20 cytotoxic drugs or drug combinations in the second-line, phase II setting of advanced, drug resistant cervix cancer. Methods Nanoparticle, albumin-bound paclitaxel (nab-paclitaxel) was administered at 125 mg/m2 IV over 30 minutes on days 1, 8 and 15 of each 28 day cycle to 37 women with metastatic or recurrent cervix cancer that had progressed or relapsed following first-line cytotoxic drug treatment. A flexible, 2-stage accrual design that allowed stopping early for lack of treatment activity was utilized. Because of slow patient accrual, the second stage was not completed. Results Of 37 patients enrolled, 2 were ineligible due to no prior cytotoxic chemotherapy, which left 35 eligible patients evaluable for response and tolerability. All of the eligible patients had 1 prior chemotherapy regimen and 27 of them had prior radiation therapy with concomitant cisplatin. The median number of nab-paclitaxel cycles were 4 (range 1–15). Ten (28.6%; CI 14.6%–46.3%) of the 35 patients had a partial response and another 15 patients (42.9%) had stable disease. The median progression-free and overall survival were 5.0 and 9.4 months, respectively. The only NCI CTCAE grade 4 event was neutropenia in 2 patients (5.7%) which resolved following dose reduction. Grade 3 neurotoxicity was reported in 1 (2.9%) patient and resolved to grade 2 following dose discontinuation. Conclusions Nab-paclitaxel has considerable activity and moderate toxicity in the treatment of drug resistant, metastatic and recurrent cervix cancer. PMID:22986144

    Time-dose fractionation factors (TDF) were calculated for 252Cf (Cf) neutron therapy versus 137Cs for intracavitary use in the preoperative treatment of bulky/barrel-shaped Stage IB cervix cancers. The endpoint assessed was gross and microscopic tumor eradication from the hysterectomy specimen. We reviewed the data obtained in clinical trials between 1976-1987 at the University of Kentucky Medical Center. Preoperative photon therapy was approximately 45 Gy of whole pelvis irradiation in 5 weeks for both 137Cs and Cf treated patients. 137Cs implant was done after pelvic irradiation x1 to a mean dose of 2104 +/- 36 cGy at point A at a dose rate of 50.5 cGy/h. There were 37.5% positive specimens. Using Cf intracavitary implants, dose varied from 109 to 459 neutron cGy in 1-2 sessions. Specimens were more frequently cleared of tumor (up to 100% at appropriate dose) and showed a dose-response relationship, both by nominal dose and by TDF adjusted analysis of dose, dose-rate, number of sessions, and overall time. Limited understanding of relative biological effectiveness, schedule, effect of implants, and dose rate all made it difficult to use TDF to study neutron effects. Relative biological effectiveness (RBE) was estimated and showed that for Cf, RBE was a complex function of treatment variables. In the pilot clinical studies, a value of 6.0 had been assumed. The present findings of RBE for tumor destruction are larger than those assumed. Cf was effective for cervix tumor therapy and produced control without significant side effects due to the brachytherapy method used. The TDF model was of limited value in the present analysis and more information is still needed for RBE, dose-rate, and fractionation effects for Cf neutrons to develop a more sophisticated and relevant model.

    Purpose: To determine the efficacy and patterns of initial failure for oral celecoxib, intravenous cisplatin, and 5-fluorouracil and concurrent pelvic radiotherapy in patients with locally advanced cancer of the cervix. Methods and Materials: Patients were treated with concurrent 5-fluorouracil and cisplatin chemotherapy and pelvic radiotherapy and brachytherapy. Celecoxib was prescribed at a dose of 400 mg twice daily for 1 year beginning on the first day of radiotherapy. The overall and disease-free survival rates were determined. Results: A total of 84 patients were accrued, of whom 78 were eligible. The estimated 2-year disease-free survival and overall survival rate was 69% and 83%, respectively. Of the 78 patients, 24 had treatment failure: 3 with persistent local disease, 9 local only, 2 regional, 4 distant, 1 regional and distant, 1 local and distant, and 2 with local, regional, and distant disease, and 1 had died of cervical cancer without a reported site of first failure and 1 without evidence of disease. Conclusion: At 2 years, the estimated disease-free survival and overall survival rate for patients with advanced cervical cancer who underwent a combination of chemoradiotherapy and celecoxib treatment was 69% and 83%, respectively. Recurrent disease developed in 24 patients, and, of those patients, 18 had a component of locoregional failure as a site of first failure. Thus, locoregional control continues to be problematic after chemoradiotherapy as delivered in our study. The identification of more active biologically targeted therapies is warranted for the treatment of advanced cancer of the cervix.

    To determine the time course and incidence of late complications from radiation therapy in patients treated with radiation for FIGO Stage IB carcinoma of the uterine cervix, and to evaluate patient and tumor factors associated with an increased probability of treatment complications. The medical records of 1784 patients with FIGO Stage IB cervical carcinoma who were treated with initial radiation therapy between 1960 and 1989 were retrospectively reviewed. Follow-up was obtained from clinic visits and correspondence with patients and their physicians. Treatment complications were graded retrospectively. Complication rates were calculated actuarially; patients who died of disease or intercurrent illness without experiencing a major complication were censored at the time of death. There were 1241, 924, 548, and 274 patients followed for more than 5, 10, 15, and 20 years, respectively. Of patients treated for Stage IB cervical carcinoma, 7.7% and 9.3% had experienced major (> or = Grade 3) complications at 3 and 5 years, respectively. After 5 years, there was a small but continuous risk of approximately 0.34% per year, resulting in an overall actuarial risk of having had major complications of 14.4% at 20 years. The risk of developing major urinary tract complications was approximately 0.7% per year for the first 3 years of follow-up, decreasing to about 0.25% per year for at least 25 years. In contrast, the risk of developing rectal complications was about 1% per year during the first 2 years, with a subsequent sharp decline to about 0.06% per year between Years 2 and 25. The risk of fistula formation was approximately doubled in the 234 patients who underwent adjuvant extrafascial hysterectomy (5.3 vs. 2.6% at 20 years; p = 0.04) and in the 111 patients who had pretreatment laparotomy (5.2 vs. 2.9%; p = 0.007). The risk of developing small bowel obstruction was increased in patients who underwent pretreatment laparotomy (14.5 vs. 3.7% at 10 years; p < 0.0001) and in

    From January, 1953 thorugh December, 1977, 910 previously untreated patients with invasive carcinoma of the uterine cervix (Stages IB-IVB) were seen at Yale-New Haven Medical Center and affiliated hospitals. An extensive retrospective analysis was undertaken in an attempt to identify prognostically significant pretreatment factors. The patients studied were uniformly staged according to the current FIGO recommendations and the majority of patients had been treated under standardized protocols combining external beam radiation therapy and intracavity radium. Pretreatment parameters - including prior medical illnesses, gross tumor characteristics, histology, and blood parameters - were studied, employing stepwise Cox regression analyses to identify the possible effects of all factors and all two-way interactions among factors on survival, disease-free survival and freedom from local-regional failure, controlling for stage of disease. FIGO stage patients age at diagnosis, pretreatment neutrophil count and hematocrit, uterine position, prior subtotal hysterectomy, histology, history of diabetes mellitus and number of pregnancies were all found to have prognostic significance. When other factors including stage of disease were controlled for, increased tumor size was associated with decreased disease-free survival and local-regional control rates.

    Radiation was until recently the key and only modality for the routine treatment of locally advanced cervical carcinoma. However after years of studying multi-modality treatments as an alternative to radiation alone in randomized phase III trials, the standard treatment has changed to chemo-radiation based on cisplatin. Three recent meta-analyses have confirmed that cisplatin-based chemo-radiation adds an absolute 12% benefit in five-year survival over radiation therapy alone. Neoadjuvant chemotherapy followed by radiation has not been of proven benefit, but when neoadjuvant chemotherapy is followed by surgery, an absolute increase of 15% in five-year survival over radiation alone is seen. This benefit in survival is comparable to that obtained with the current chemo-radiation schedules based on cisplatin. Despite these encouraging results there remains room for improvement as the five-year survival of patients treated with chemo-radiation ranges from nearly 80% in bulky IB tumours to only 25% in stage IVA disease. Other therapeutic approaches need to be fully evaluated including the use of chemo-radiation after neoadjuvant chemotherapy; the use of new drug combinations and the multi-modality combination of neoadjuvant chemotherapy followed by radical surgery plus adjuvant chemo-radiation. Likewise, the addition of radiosensitizers to cisplatin, preoperative chemo-radiation and/or adjuvant chemotherapy may eventually improve the currents results of cisplatin-based chemo-radiation. Nevertheless, it is hard to foresee a dramatic increase in cure rate, even with the most optimal combination of cytotoxic drugs, surgery and radiation, and thus the testing of molecular targeted therapies against cervical cancer is a logical step to follow.

    Pulmonary sarcomatoid carcinoma is a rare subtype of non-small cell lung cancer with a poor prognosis. We herein report on a case of pulmonary sarcomatoid carcinoma that was treated successfully by concurrent chemoradiotherapy. A 65-year-old man was diagnosed to have pulmonary pleomorphic carcinoma (clinical T4N2M0 stage IIIB). He received concurrent chemoradiotherapy (60 Gy of radiotherapy in 30 fractionations and two courses of chemotherapy with carboplatin and paclitaxel). After chemoradiotherapy, a significant reduction of the tumor size was observed. Two courses of adjuvant chemotherapy were performed. He is currently alive at 15 months after the first treatment without any recurrence or metastasis. PMID:27853077

    This meta-analysis was performed to compare the outcomes between NACT-S and RT for locally advanced cancer cervix. The primary end points were survival benefits. The data sources for the search included medline, national library of medicine, and the embase search engines. Inclusion criteria included studies published between 2000 and 2012, and FIGO stages IB2 to IVA. Studies had to be properly randomized, prospective, or retrospective and only phase III. Further, the studies had to be with two arms, including one arm for neoadjuvant chemotherapy then-surgery (NACT-S), and the other arm for radiotherapy (RT). Data were collected from 1171 patients enrolled in seven phase III trials. The 5-year PFS (progression-free survival) for NACT-S and RT were 62 and 45.5 %, respectively. The 5-year OS for NACT-S and RT were 66 and 49 %, respectively. NACT-S was associated with better late toxicities compared to RT. NACT-S is a reasonable treatment option for locally advanced cancer cervix. It achieved better results than RT, especially for stages from IB2 to IIB.

    Purpose: To evaluate whether pretreatment carcinoembryonic antigen (CEA) levels have a prognostic role in patients after definitive radiotherapy for squamous cell carcinoma (SCC) of the uterine cervix. Methods and Materials: A retrospective study of 550 patients was performed. The SCC antigen (SCC-Ag) and CEA levels were regarded as elevated when they were {>=}2 and {>=}5 ng/mL, respectively. A total of 208 patients underwent concurrent chemoradiotherapy (CCRT). The Kaplan-Meier method was used to calculate the distant metastasis (DM), local failure (LF), disease-free survival (DFS), and overall survival (OS) rates. Multivariate analysis was performed using the Cox proportional hazards model. The hazard ratio (HR) with 95% confidence interval (CI) was evaluated for the risk of a poor prognosis. Results: Compared with the patients with normal CEA/SCC-Ag levels, CEA levels {>=}10 ng/mL but without elevated SCC-Ag levels was an independent factor for LF (HR, 51.81; 95% CI, 11.51-233.23; p < .001), DM (HR, 6.04; 95% CI, 1.58-23.01; p = .008), DFS (HR, 10.17; 95% CI, 3.18-32.56; p < .001), and OS (HR, 5.75; 95% CI, 1.82-18.18; p = .003) after RT alone. However, no significant role for CEA was noted in patients with SCC-Ag levels {>=}2 ng/mL. In patients undergoing CCRT, a CEA level {>=}10 ng/mL was an independent factor for LF (HR, 2.50; 95% CI, 1.01-6.21; p = .047), DM (HR, 3.41; 95% CI, 1.56-7.46; p = .002), DFS (HR, 2.73; 95% CI, 1.39-5.36; p = .003), and OS (HR, 3.93; 95% CI 1.99-7.75; p < .001). A SCC-Ag level of {>=}40 ng/mL was another prognostic factor for DM, DFS, and OS in patients undergoing not only CCRT, but also RT alone. The 5-year OS rate for CCRT patients with CEA <10 ng/mL and {>=}10 ng/mL was 75.3% and 35.8%, respectively (p < .001). CCRT was an independent factor for better OS (HR, 0.69; 95% CI, 0.50-0.97; p = .034). Conclusion: Pretreatment CEA levels in patients with SCC of the uterine cervix provide complementary information for predicting LF, DM

    Cutaneous squamous cell carcinoma is one of the most common non-melanoma skin cancers worldwide. While most cutaneous squamous cell carcinomas are easily managed, there is a high-risk subset of tumors that can cause severe morbidity and mortality. Tumor characteristics as well as patient characteristics contribute to the classification of cutaneous squamous cell carcinomas as low-risk vs. high-risk. Advances in the treatment of cutaneous squamous cell carcinomas largely relate to the management of this high-risk subset. Surgical and non-surgical management options, including newer targeted molecular therapies, will be discussed here. Larger, multicenter studies are needed to determine the exact significance of individual risk factors with respect to aggressive clinical behavior and the risks of metastasis and death, as well as the role of surgical and adjuvant therapies in patients with high-risk cutaneous squamous cell carcinomas.

    For locally-advanced uterine cancer clinically extending to the cervix, two treatment paradigms exist: surgical staging radical hysterectomy with tailored adjuvant therapy or neoadjuvant therapy followed by a less extensive simple hysterectomy. Currently, insufficient data exists to guide consensus guidelines and practical application of preoperative radiotherapy. Retrospective IRB approved cohort study from 1999 to 2014 of 36 endometrial cancer patients with clinical involvement of cervix±parametria treated with neoadjuvant external beam radiotherapy (45-50.4Gy in 25-28 fractions) and image-based HDR brachytherapy (5-5.5Gy times 3-4 fractions)±chemotherapy followed by extrafascial hysterectomy performed at a median of 6weeks after radiotherapy. All patients had clinical cervical extension, 50% also had parametria extension, and 31% had nodal involvement. At the time of surgery 91% had no clinical cervical involvement, 58% had no pathologic cervical involvement, and all had margin negative resection. The pathologic complete response rate was 24%. Median follow-up from the time of surgery was 20months (range: 0-153). The 3-year local control, regional control, distant control, disease free survival and overall survival rates were 96%, 89%, 84%, 73%, and 100%. The 3-year rate of grade 3 complications was 11%, with no grade 4+ toxicity. Neoadjuvant radiation therapy±chemotherapy followed by extrafascial hysterectomy appears to be a viable option for patients with endometrial cancer clinically extending to the cervix and parametria. The HDR brachytherapy schema of 5-5.5Gy times 3-4 fractions, for a cumulative EQD2 of 60-70Gy, is well tolerated with high rates of clinical and pathological response. Copyright © 2014 Elsevier Inc.

    Interstitial and endocavity ultrasound devices have been developed specifically for applying hyperthermia within temporary HDR brachytherapy implants during radiation therapy. Catheter-based ultrasound applicators are capable of 3D spatial control of heating in both angle and length of the devices, with enhanced radial penetration of heating compared to other hyperthermia technologies. A pilot study of the combination of catheter based ultrasound with HDR brachytherapy for locally advanced prostate and cervical cancer has been initiated, and preliminary results of the performance and heating distributions are reported herein. The treatment delivery platform consists of a 32 channel RF amplifier and a 48 channel thermocouple monitoring system. Controlling software can monitor and regulate frequency and power to each transducer section as required during the procedure. Interstitial applicators consist of multiple transducer sections of 2-4 cm length×180 deg and 3-4 cm×360 deg. heating patterns to be inserted in specific placed 13g implant catheters. The endocavity device, designed to be inserted within a 6 mm OD plastic tandem catheter within the cervix, consists of 2-3 transducers x dual 180 or 360 deg sectors. 3D temperature based treatment planning and optimization is dovetailed to the HDR optimization based planning to best configure and position the applicators within the catheters, and to determine optimal base power levels to each transducer section. To date we have treated eight cervix implants and four prostate implants. 100% of treatments achieved a goal of >60 min duration, with therapeutic temperatures achieved in all cases. Thermal dosimetry within the hyperthermia target volume (HTV) and clinical target volume (CTV) are reported. Catheter-based ultrasound hyperthermia with HDR appears feasible with therapeutic temperature coverage of the target volume within the prostate or cervix while sparing surrounding more sensitive regions.

    For locally advanced squamous cell carcinoma of the anal canal, efforts to discover effective treatments that would protect sphincter preservation led to the development of combined chemoradiotherapy, which, when administered appropriately, is curative. While the standard of combined modality chemoradiotherapy has minimally changed over the past 30 years, various chemotherapeutic and biologic agents, as well as novel methods for delivering radiation, have enhanced the treatment of anal carcinoma and are continuously being explored. This review examines the risk factors associated with anal carcinoma, and subsequently discusses the current standard of care from diagnosis through surveillance, paying attention to the pivotal trials that have shaped modern treatment paradigms.

  10. Advances in the pathology of penile carcinomas.

    2012-06-01

    The incidence of penile cancer varies from country to country, with the highest figures reported for countries in Africa, South America, and Asia and lowest in the United States and Europe. Causes of this variation are not clear, but they are thought to be related to human papillomavirus infection, smoking, lack of circumcision, chronic inflammation, and poor genital hygiene. Most penile tumors are squamous cell carcinomas, and a variegated spectrum of distinct morphologies is currently recognized. Each one of these subtypes has distinctive pathologic and clinical features. About half of penile carcinomas are usual squamous cell carcinomas, and the rest corresponds to verrucous, warty, basaloid, warty-basaloid, papillary, pseudohyperplastic, pseudoglandular, adenosquamous, sarcomatoid, and cuniculatum carcinomas. Previous studies have found a consistent association of tumor cell morphology and human papillomavirus presence in penile carcinomas. Those tumors composed of small- to intermediate-sized, basaloid ("blue") cells are often human papillomavirus positive, whereas human papillomavirus prevalence is lower in tumors showing large, keratinizing, maturing eosinophilic ("pink") cells. Human papillomavirus-related tumors affect younger patients, whereas human papillomavirus-unrelated tumors are seen in older patients with phimosis, lichen sclerosus, or squamous hyperplasia. This morphologic distinctiveness is also observed in penile intraepithelial neoplasia. The specific aim of this review is to provide a detailed discussion on the macroscopic and microscopic features of all major subtypes of penile cancer. We also discuss the role of pathologic features in the prognosis of penile cancer, the characteristics of penile precursor lesions, and the use of immunohistochemistry for the diagnosis of invasive and precursor lesions.

    The purpose of this study was to identify the optimal local treatment modalities for International Federation of Gynecology and Obstetrics (FIGO) stage I-II small-cell carcinoma of the cervix (SCCC), including cancer-directed surgery (CDS) and/or radiotherapy (RT). The Surveillance Epidemiology and End Results (SEER) database was used to identify SCCC patients from 1988 to 2012, and analyzed using Kaplan-Meier survival and Cox regression proportional hazard methods to determine factors significant for cause-specific survival (CSS) and overall (OS). A total of 208 patients of SCCC were enrolled. The median follow-up time was 31 months. Fifty-eight (27.9%) patients were treated with primary CDS, 88 (42.3%) patients underwent CDS combined with RT, and 62 (29.8%) patients were treated with primary RT. Univariate and multivariate analyses showed that local treatment modalities were independent prognostic factors for CSS and OS. Patients who had undergone CDS had better CSS and OS, compared with patients who had been treated with combined CDS and RT or RT alone. The 5-year CSS and OS of entire group was 49.8% and 46.4%, respectively. The 5-year CSS in the groups of patients receiving CDS, CDS combined with RT, and RT alone were 67.9%, 49.7%, and 32.6%, respectively (P < 0.001). The 5-year OS in patients treated with CDS, CDS combined with RT, and RT alone were 64.9%, 46.2%, and 28.8% (P < 0.001). Primary surgery was associated with improved CSS and OS for FIGO stage I and lymph node negative disease. Primary surgery is the most effective local treatment for FIGO stage I-II SCCC, as adjuvant RT or radical RT does not improve survival compared to radical surgery, especially in patients with FIGO stage I and lymph node negative disease.

    Purpose: To evaluate and compare the efficacy of medium-dose-rate (MDR) and low-dose-rate (LDR) intracavitary brachytherapy (ICBT) for uterine cervical cancer. Methods and Materials: We evaluated 419 patients with squamous cell carcinoma of the cervix who were treated by radical radiotherapy with curative intent at Tokyo Women's Medical University from 1969 to 1999. LDR was used from 1969 to 1986, and MDR has been used since July 1987. When compared with LDR, fraction dose was decreased and fraction size was increased (1 or 2 fractions) for MDR to make the total dose of MDR equal to that of LDR. In general, the patients received a total dose of 60 to 70 Gy at Point A with external beam radiotherapy combined with brachytherapy according to the International Federation of Gynecology and Obstetrics stage. In the LDR group, 32 patients had Stage I disease, 81 had Stage II, 182 had Stage III, and 29 had Stage IVA; in the MDR group, 9 patients had Stage I disease, 19 had Stage II, 55 had Stage III, and 12 had Stage IVA. Results: The 5-year overall survival rates for Stages I, II, III, and IVA in the LDR group were 78%, 72%, 55%, and 34%, respectively. In the MDR group, the 5-year overall survival rates were 100%, 68%, 52%, and 42%, respectively. No significant statistical differences were seen between the two groups. The actuarial rates of late complications Grade 2 or greater at 5 years for the rectum, bladder, and small intestine in the LDR group were 11.1%, 5.8%, and 2.0%, respectively. The rates for the MDR group were 11.7%, 4.2%, and 2.6%, respectively, all of which were without statistical differences. Conclusion: These data suggest that MDR ICBT is effective, useful, and equally as good as LDR ICBT in daytime (about 5 hours) treatments of patients with cervical cancer.

    Purpose: This study evaluated the treatment results of external beam radiotherapy administered in six fractions per week and high-dose-rate (HDR) brachytherapy for the treatment of cervical cancer. Methods and Materials: From July 2000 to July 2003, 43 patients were enrolled in this study. The patients received 45 Gy from a 10-MV photon beam using four-field box or anterior-posterior beams. Parametrial regions and the pelvic side walls were boosted with up to 50.4 Gy using a midline block. The daily fraction dose was 1.8 Gy administered in six-weekly fractions, from Monday to Saturday. HDR brachytherapy was also delivered at doses of 24 Gy to point A in six fractions twice a week. The median follow-up time was 37 months (range, 9-60 months). Results: The median overall treatment time was 51 days for all patients (range, 44-62 days). Thirty-four patients (79.1%) achieved complete remission and 8 (18.6%) achieved partial remission after radiotherapy. Locoregional recurrence occurred in 5 patients (11.6%), and a distant metastasis was encountered in 6 patients (13.9%). The 3-year overall survival, locoregional, and distant metastasis-free survival rates were 74.7%, 87.8%, and 84.7%, respectively. Grade 2 and 3 late rectal complications were encountered in 3 (6.5%) and 1 (2.2%), respectively. There were no Grade 3 late bladder complications. Conclusions: Six fractions per week of external beam radiotherapy and HDR brachytherapy is an effective treatment for patients with a carcinoma of the uterine cervix and can be used as a possible alternative to concomitant chemoradiotherapy in elderly patients or in patients with co-morbidity.

    Patients with advanced basal cell carcinoma due to local extension or metastatic disease were previously at a therapeutic impasse. Targeted inhibition of the sonic hedgehog pathway by vismodegib represents a new therapeutic strategy. Adnexal carcinomas are rare malignant skin tumours derived from epithelial annexes. Conventional treatment of adnexal tumours is based on surgical excision. Although the radiosensitivity of adnexal carcinomas has not been established, radiotherapy could be offered alone or in combination in locally advanced or inoperable disease. Chemotherapy represents a therapeutic option in the treatment of metastatic adnexal tumours. Currently there is no effective treatment for these tumours when they become metastatic or unresectable, and treatment is palliative. Sunitinib represents a new therapeutic strategy, with efficiency described in the literature for a small number of patients. However, its efficacy is partial, and its tolerance is not always good. We report a patient with trichoblastic carcinoma, initially diagnosed as basal cell carcinoma, treated effectively with vismodegib. The remarkable response we have observed in this patient suggests an encouraging therapeutic role of vismodegib in trichoblastic carcinoma that should be evaluated in a carefully designed trial.

    This Phase III randomized trial examined the effect of two low dose rates (0.73 or 0.38 Gy[center dot]h[sup [minus]1]) on the local control, survival, relapse-free survival, complications, and secondary effects in the treatment of cervical cancers. A total of 204 Stage Ib or II cervical carcinoma patients were included between January 1985 and September 1988. Treatment consisted of uterovaginal [sup 137]Cs irradiation followed by surgery. The two groups were similar for age, tumor stage and medical or surgical history. Their brachytherapy parameters were also similar (60 Gy pear dimensions, dose to critical organs, total kerma, etc....). There were no differences in the short-term effects or therapeutic outcome. However, overall complications and side effects observed after 6 months were significantly more frequent (p < 0.01) in the higher dose rate group. 40 refs., 4 figs., 6 tabs.

    We recently reported one interesting case showing mutation-free c-KIT proto-oncogene overexpression and paradoxical hypermethylation in 54 cases of primary squamous cell carcinoma of uterine cervix (SCC). However, its molecular mechanisms still remain unknown. We propose the hypothesis that increased methylation at the CpG islands on the promoter near the first exon region might interfere with the binding of CTCF repressor with c-KIT promoter that regulates c-KIT proto-oncogene expression in such case. Further studies focusing on the status of epigenetic modifications of mutation-free c-KIT (+) tumors are encouraged.

    Merkel cell carcinoma (MCC) is a rare and lethal skin cancer with few known treatment options. Management of this disease is challenging, and oncology nurses must understand the medical, physical, and psychosocial burden that MCC places on the patient and family caregivers. Patients must navigate a complex medical and insurance network that often fails to support patients with rare cancers. Nurses must advocate for these patients to ensure quality comprehensive cancer care.

    Most cervix cancer cases occur in low-income and middle-income countries (LMIC), and outcomes are suboptimal, even for early stage disease. Brachytherapy plays a central role in the treatment paradigm, improving both local control and overall survival. The American Brachytherapy Society (ABS) aims to provide guidelines for brachytherapy delivery in resource-limited settings. A panel of clinicians and physicists with expertise in brachytherapy administration in LMIC was convened. A survey was developed to identify practice patterns at the authors' institutions and was also extended to participants of the Cervix Cancer Research Network. The scientific literature was reviewed to identify consensus papers or review articles with a focus on treatment of locally advanced, unresected cervical cancer in LMIC. Of the 40 participants invited to respond to the survey, 32 responded (response rate 80%). Participants were practicing in 14 different countries including both high-income (China, Singapore, Taiwan, United Kingdom, and United States) and low-income or middle-income countries (Bangladesh, Botswana, Brazil, India, Malaysia, Pakistan, Philippines, Thailand, and Vietnam). Recommendations for modifications to existing ABS guidelines were reviewed by the panel members and are highlighted in this article. Recommendations for treatment of locally advanced, unresectable cervical cancer in LMIC are presented. The guidelines comment on staging, external beam radiotherapy, use of concurrent chemotherapy, overall treatment duration, use of anesthesia, applicator choice and placement verification, brachytherapy treatment planning including dose and prescription point, recommended reporting and documentation, physics support, and follow-up.

    The objective was to evaluate the frequency and prognostic significance of occult supraclavicular lymph node metastases identified by 2-[(18)F]fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET) in patients with cervical carcinoma. Between March 1998 and January 2002, 186 patients with a new diagnosis of cervical cancer underwent whole-body FDG-PET before therapy. Fourteen patients had abnormal FDG uptake in left supraclavicular lymph nodes without palpable disease. All 14 patients underwent sonographically guided fine-needle aspiration of the left supraclavicular lymph nodes. One patient refused therapy, 6 were treated with palliative intent, and 7 received definitive irradiation and concurrent chemotherapy. Survival was calculated by the Kaplan-Meier method. The overall frequency of FDG-positive left supraclavicular lymph nodes was 8% (14/186). Metastasis was pathologically confirmed in all 14 patients. Therefore, the positive predictive value of abnormal FDG uptake in left supraclavicular lymph nodes was 100%. Nineteen percent of all patients (35/186) had abnormal FDG uptake in para-aortic lymph nodes. The frequency of positive FDG uptake in the left supraclavicular lymph nodes was 40% (14/35) in those with para-aortic lymph node uptake and 15% in those with stage IIIb disease. The median overall survival was 7.5 months. At last follow-up, 11 patients were dead and 3 were alive with disease. All patients developed metastatic disease, most commonly to bone and lung. The positive predictive value of abnormal FDG uptake in left supraclavicular lymph nodes was 100%. Prognosis for these patients was dismal despite aggressive therapy.

    This study aimed to determine the utility and a cut-off level of serum squamous cell carcinoma antigen (SCC-Ag) to predict lymph node metastasis in locally advanced cervical cancer cases. We also investigated the correlation between SCC-Ag level and lymph node status. From June 2009 to June 2014, 232 patients with cervical cancer stage IB2-IVA, who were treated at Ramathibodi Hospital, were recruited. Receiver operating characteristic (ROC) curves were used to identify the best cut-off point of SCC-Ag level to predict lymph node metastasis. Quantile regression was performed to evaluate the correlation between SCC-Ag levels and pelvic lymph node metastasis, paraaortic lymph node metastasis, and parametrial involvement as well as tumor size. Pelvic lymph node metastasis and paraaortic lymph node metastasis were diagnosed in 46.6% and 20.1% of the patients, respectively. The median SCC-Ag level was 6 ng/mL (range, 0.5 to 464.6 ng/ mL). The areas under ROC curves between SCC-Ag level and pelvic lymph node metastasis, paraaotic lymph node metastasis, parametrial involvements were low. SCC-Ag level was significantly correlated with paraaortic lymph node status (p=0.045) but not with pelvic lymph node status and parametrial involvement. SCC-Ag level was also related to the tumor diameter (p<0.05). SCC-Ag level is not a good predictor for pelvic and paraaortic lymph node metastasis. However, it is still beneficial to assess the tumor burden of squamous cell carcinoma of the cervix.

    Between May 1986 and September 1990 a total of 43 patients with metastatic transitional cell carcinoma (TCC) of the urinary tract have been treated at our institution with combination chemotherapy (CMV) consisting of cisplatin 100 mg m-2 i.v. day 2; methotrexate 30 mg m-2 i.v. days 1.8; and vinblastine 4 mg m-2 i.v. days 1.8. Chemotherapy was recycled on day 22 and continued for a maximum of six cycles in responding patients. Of 33 patients with measurable disease 8 (24%) achieved a complete remission (CR). The median survival for patients achieving a CR was 13 months (range 5-29+) whilst the median survival for all 43 patients was 7 months (range 1-29+). Only three patients are still alive--two are disease free. More effective and/or less toxic chemotherapy regimens are needed for the treatment of patients with metastatic TCC. PMID:1520591

    Adenoid cystic carcinoma (ACC) of the breast is a rare special subtype of breast cancer characterized by the presence of a dual cell population of luminal and basaloid cells arranged in specific growth patterns. Most breast cancers with triple-negative, basal-like breast features (i.e., tumors that are devoid of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression, and express basal cell markers) are generally high-grade tumors with an aggressive clinical course. Conversely, while ACCs also display a triple-negative, basal-like phenotype, they are usually low-grade and exhibit an indolent clinical behavior. Many discoveries regarding the molecular and genetic features of the ACC, including a specific chromosomal translocation t(6;9) that results in a MYB-NFIB fusion gene, have been made in recent years. This comprehensive review provides our experience with the ACC of the breast, as well as an overview of clinical, histopathological, and molecular genetic features. PMID:25516849

    Management of advanced hepatocellular carcinoma (HCC), one of the most lethal cancers worldwide, has presented a therapeutic challenge over past decades. Most patients with advanced HCC and a low possibility of surgical resection have limited treatment options and no alternative but to accept local or palliative treatment. In the new era of cancer therapy, increasing numbers of molecular targeted agents (MTAs) have been applied in the treatment of advanced HCC. However, mono-targeted therapy has shown disappointing outcomes in disease control, primarily because of tumor heterogeneity and complex cell signal transduction. Because incapacitation of a single target is insufficient for cancer suppression, combination treatment for targeted therapy has been proposed and experimentally tested in several clinical trials. In this article, we review research studies aimed to enhance the efficacy of targeted therapy for HCC through combination strategies. Combination treatments involving targeted therapy for advanced HCC are compared and discussed. PMID:27626176

    Twenty-five patients with advanced metastatic breast cancer were treated with the combination of methotrexate 60 mg/M2 and 5-fluorouracil 700 mg/M2 intravenously on the first and eighth days, and cyclophosphamide 100 mg/M2 and prednisone 40 mg/M2 by mouth daily for the first 14 days of a 28-day cycle. The patients had had no previous chemotherapy or extensive radiotherapy and all but two had not responded to hormonal therapy or endocrine ablation. The major metastatic lesions were: lung (12 patients), liver (four patients), bone (four patients), soft tissue (three patients), nodes (two patients). Seventeen of the 25 patients (68%) responded to treatment with seven complete remissions; these included patients suffering metastatic lesions in the lung, nodes, and soft tissue. The overall median duration of response was nine months (range 6-26 months). Toxicity was primarily haematological, but the group received an average of at least 75% of their calculated dose for each monthly cycle. Haematological toxicity was most pronounced in patients with liver dysfunction and bone marrow involvement. Out of eight nonresponders seven died, with a median survival of six months. Only six of 17 responders died, and the median survival in this group will exceed thirteen months. There was no correlation between the length of the metastasis-free interval after previous treatment and subsequent response to chemotherapy. PMID:4818162

    Primary liver cancer, mainly consisting of hepatocellular carcinoma (HCC), is one of common malignancies worldwide, and prevalent among the Chinese population. A diagnosis of early stage HCC has proven to be very difficult because of its insidious feature in onset and development. At the time of diagnosis, most HCC cases are locally advanced and/or distant metastatic, which results in difficulty to be treated and poor prognosis. For advanced HCC, systemic therapy is frequently adopted as an important palliative method. In recent years, clinical studies and observations have often reported about systemic anti-cancer therapy of advanced HCC, including molecular target therapy, systemic chemotherapy and immunotherapy. In this article, we review these treatment modalities to provide a reference for clinicians. PMID:27547002

    Trans-abdominal ultrasonography (US) is capable of determining size, shape, thickness, and diameter of uterus, cervix and disease at cervix or parametria. To assess the potential value of US for image-guided cervical cancer brachytherapy, we compared US-findings relevant for brachytherapy to the corresponding findings obtained from MR imaging. Twenty patients with biopsy proven cervical cancer undergoing definitive radiotherapy with/without concomitant Cisplatin chemotherapy and suitable for brachytherapy were invited to participate in this study. US and MR were performed in a similar reproducible patient positioning after intracavitary application. US mid-sagittal and axial image at the level of external cervical os was acquired. Reference points D1 to D9 and distances were identified with respect to central tandem and flange, to delineate cervix, central disease, and external surface of the uterus. Thirty-two applications using CT/MR compatible applicators were evaluable. The D1 and D3 reference distances which represent anterior surface had a strong correlation with R=0.92 and 0.94 (p<0.01). The D2 and D4 reference distances in contrast, which represent the posterior surface had a moderate (D2) and a strong (D4) correlation with R=0.63 and 0.82 (p<0.01). Of all, D2 reference distance showed the least correlation of MR and US. The D5 reference distance representing the fundal thickness from tandem tip had a correlation of 0.98. The reference distances for D6, D7, D8, and D9 had a correlation of 0.94, 0.82, 0.96, and 0.93, respectively. Our study evaluating the use of US, suggests a reasonably strong correlation with MR in delineating uterus, cervix, and central disease for 3D conformal intracavitary brachytherapy planning.

    Tuberculosis (TB) of the cervix is a rare disease, especially in developed countries. We presented a patient with primary TB of the cervix with no concurrent immune deficiency or HIV infections. The case clinically mimicked carcinoma of the cervix. Difficulties in diagnosis have been discussed. Given the recent increase in migration patterns including travel from TB endemic areas, an abnormal-looking cervix should be regarded with a degree of suspicion for TB.

    A case of postirradiation sarcoma is described. The tumor, a malignant fibrous histiocytoma, occurred in the radiation field 11 years following postoperative external beam radiation therapy (7000 rad) for carcinoma of the cervix. Reports of postirradiation malignant fibrous histiocytoma are rare, and the occurrence of this neoplasm following treatment of cervix cancer has not previously been described. The literature concerning postirradiation bone and soft tissue sarcomas is briefly reviewed, with special attention to malignant fibrous histiocytomas.

  9. Vismodegib: in locally advanced or metastatic basal cell carcinoma.

    Vismodegib is the first Hedgehog pathway inhibitor to be approved in the US, where it is indicated for the treatment of adults with metastatic basal cell carcinoma (BCC), or with locally advanced BCC that has recurred following surgery or who are not candidates for surgery, and who are not candidates for radiation. Vismodegib selectively and potently inhibits the Hedgehog signalling pathway by binding to Smoothened, thereby inhibiting the activation of Hedgehog target genes. Oral vismodegib was effective in the treatment of patients with locally advanced (n = 63) or metastatic (n = 33) BCC, according to the results of an ongoing, noncomparative, multinational, pivotal, phase II trial (ERIVANCE BCC). In this trial (using a clinical cutoff date of 26 November 2010), the independent review facility overall response rate was 42.9% in patients with locally advanced BCC and 30.3% in patients with metastatic BCC. In both patients with locally advanced BCC and those with metastatic BCC, the median duration of response was 7.6 months and median progression-free survival was 9.5 months. Oral vismodegib had an acceptable tolerability profile in patients with advanced BCC.

    Hepatocellular carcinoma (HCC) is a critical global health issue and the third most common cause of cancer-related deaths worldwide. The majority of patients who present HCC are already at an advanced stage and their tumors are unresectable. Sorafenib is a multi-kinase inhibitor of the vascular endothelial growth factor pathway and was recently introduced as a therapy for advanced HCC. Furthermore, studies have shown that oral sorafenib has beneficial effects on survival. However, many patients experience diverse side effects, and some of these are severe. Liver abscess development has not been previously documented to be associated with sorafenib administration in HCC. Here, we report the case of a HCC patient that developed a liver abscess while being treated with sorafenib.

    Enteropancreatic (EP) neuroendocrine carcinomas (NECs) represent relatively rare and heterogeneous malignancies. They are the most common group among neuroendocrine tumors (NETs). In most cases they are advanced at diagnosis and slow-growing, therefore conditioning a better prognosis compared with non neuroendocrine carcinomas from the same sites. No standard medical therapy exists, except for somatostatin analogs in functioning tumors, and octreotide LAR in functioning or non functioning well differentiated NECs from small bowel. Several systemic therapeutic options exist, including chemotherapy, somatostatin analog, interferon, peptide receptor radionuclide therapy (PRRT), and molecular targeted drugs. Among them some therapies have specific biological tumor targets and can be defined as "biological targeted therapies". This review focuses on the status of EP NECs targeted therapies in the light of recent advances. Somatostatin receptors (SSTRs) are the first therapeutic target detected in EP NECs. Through them SS analogs and PRRT act, producing symptomatic, biochemical, and, to a lesser extent, antiproliferative effects. New SS analogs, covering a higher number of SSTR subtypes, were developed, including pasireotide (SOM230), which controls 25% of carcinoid syndromes resistant to full dose octreotide LAR. Chimeric analogs, which bind SSTR2/SSTR5 and dopamine-2 receptor subtype (D2), are in preclinical phase of development. Among the numerous molecular targeted agents investigated in NETs, mTOR inhibitors and VEGF/VEGFR/PDGFR inhibitors are in most advanced clinical phase of investigation. In particular, everolimus, sunitinib, and bevacizumab are all studied in phase III trials. Both everolimus and sunitinib produced significant survival benefit versus placebo in advanced progressing well-differentiated pancreatic NECs. Sunitinib data have been presented at the last ASCO in June 2010, and everolimus data will be presented at next ESMO in September 2010. Copyright

  12. Control of cancer of the cervix uteri*

    PubMed Central

    1986-01-01

    Cancer of the uterine cervix is a global problem. It is the most common cancer in women in developing countries and is the second most common cancer in women worldwide, with approximately half a million new cases each year. It is strongly linked with an early onset of sexual activity and multiple sexual partners; recent evidence points to a causal link between some of the precursor lesions of this cancer and specific papillomavirus infections. Cervical cancer has significant morbidity and mortality if it is not detected before it reaches an advanced stage with symptoms. If the disease is detected in an early asymptomatic stage it is nearly always curable by surgery or radiotherapy. Therefore today, cytological screening is the mainstay for control of cervical cancer. In some developed countries, screening programmes for cervical carcinoma have been in operation for many years. In places where large well-organized programmes have been functioning, significant decreases in mortality, in the range of 50-60%, have been observed. The favourable effects result primarily from the removal of intraepithelial lesions preventing the occurrence of invasive tumours. In countries where resources are limited, the aim should be to screen every woman once in her lifetime between 35 and 40 years of age. When more resources are available the frequency of screening should be increased to once every ten or five years for the age groups 35 to 55 years and, ideally, once every three years for women aged between 25 and 60 years.

    Objectives To investigate the feasibility of performing a fresh-tissue, in vitro radiation resistance assay (IVRRA) in a cooperative group setting and to assess the association of IVRRA results with clinical outcomes. Methods Women with Stages IIB-IVA carcinoma of the uterine cervix without obvious para-aortic lymphadenopathy on imaging were eligible. Primary tumor biopsies were shipped to a central testing facility where agar-based cell suspensions were exposed to 300 cGy of RT ± cisplatin and cultured for 5 days. 3H-thymidine incorporation was used to determine percent cell inhibition (PCI) of test specimen compared to that of the untreated control. Tumors were considered to exhibit extreme radiation resistance (ERR), intermediate radiation resistance (IRR) or low radiation resistance (LRR) based on a standard data set from 39 previously studied specimens. Standardized doses of external beam radiation and intracavitary brachytherapy, when feasible, in addition to platinum-based chemotherapy were mandated. Progression-free survival (PFS) was the primary endpoint. Clinical response and overall survival (OS) were secondary endpoints. Clinical investigators were blinded to assay data and vice versa. Results Thirty-six patients were enrolled, but analysis was limited to 17 patients whose specimens were adequate for IVRRA. The median follow-up time was 40 months. There was no association between IVRRA and response. In the Cox model, IRR/ERR tumors showed worse PFS [HR=11.2 (95% CI 1.3–96, p=0.03)] and worse OS [HR=11.7 (95% CI 1.4–99.6, p=0.03)] compared to LRR tumors when IVRRA was performed with RT alone, but there were no associations between IVRRA and PFS or OS when cisplatin was added to the IVRRA. Conclusions IVRRA (RT alone) results correlated with PFS and OS in this prospective trial, but follow-up trials are indicated to address feasibility and to confirm results in an expanded cohort. If confirmed, IVRRA could potentially direct molecular identification

    2014-01-01

    For patients with metastatic or locally advanced eyelid and periocular carcinoma not amenable to surgical excision, targeted therapies have shown efficacy with better tolerability compared to cytotoxic chemotherapy. Overexpression of epithelial growth factor receptor was found in squamous cell carcinomas. Vismodegib targets the mutation in the hedgehog pathway identified in basal cell carcinoma and basal cell nevus syndrome. Targeted therapies provide a novel and potentially effective treatment alternative for patients with eyelid carcinoma not amendable for surgery, including those with metastatic, locally advanced disease, advanced age, and significant comorbidities. High cost, need for long-term treatment, and toxicity are relative limitations. PMID:25232546

    Radiotherapy techniques have substantially improved in the last two decades. After the introduction of 3-dimensional conformal radiotherapy, radiotherapy has been increasingly used for the treatment of hepatocellular carcinoma (HCC). Currently, more advanced techniques, including intensity-modulated radiotherapy (IMRT), stereotactic ablative body radiotherapy (SABR), and charged particle therapy, are used for the treatment of HCC. IMRT can escalate the tumor dose while sparing the normal tissue even though the tumor is large or located near critical organs. SABR can deliver a very high radiation dose to small HCCs in a few fractions, leading to high local control rates of 84%-100%. Various advanced imaging modalities are used for radiotherapy planning and delivery to improve the precision of radiotherapy. These advanced techniques enable the delivery of high dose radiotherapy for early to advanced HCCs without increasing the radiation-induced toxicities. However, as there have been no effective tools for the prediction of the response to radiotherapy or recurrences within or outside the radiation field, future studies should focus on selecting the patients who will benefit from radiotherapy.

    Objective: To investigate the factors favoring a positive prognosis for advanced primary peritoneal carcinoma (PPC). Methods: Twenty-four cases meeting the criteria for PPC were analyzed retrospectively for the clinicopathologic profiles. Immunohistochemistry was used to determine the expressions of p53, Top2α, Ki-67 and Her-2/neu. Then all these clinicopathological factors and molecular markers were correlated with the prognosis. Results: There were 15 cases of primary peritoneal serous papillary carcinoma (PPSPC), 6 cases of mixed epithelial carcinoma (MEC) and 3 cases of malignant mixed Mullerian tumor (MMMT). All patients underwent cytoreductive surgery with optimal debulking achieved in 3 cases. Among those receiving first-line chemotherapy, 13 patients received the TP regimen (paclitaxel-cisplatin or carboplatin) and 7 patients received the PAC regimen (cisplatin-doxorubicin-cyclophosphamide). The median overall survival of all patients was 42 months, while the breakdown for survival time for patients with PPSPC, MMT and MEC was 44, 13 and 19 months, respectively. The expressions of p53, Top2α and Ki-67 were all demonstrated in 11 cases respectively. None showed the expression of Her-2/neu. There were significant differences in the median survival between patients with PPSPC and those with MMMT (44 months vs 13 months, P<0.05), also between patients receiving TP combination and those receiving the PAC regimen (75 months vs 28 months, P<0.05). Another significant difference in the median progression-free survival (PFS) was identified between patients with positive p53 immunostaining and those with negative p53 immunostaining (15 months vs 47 months, P<0.05), whereas age, menopausal status, residual tumor size and the other molecular factors did not significantly impact survival. Conclusion: Patients with PPC should be treated with a comprehensive management plan including appropriate cytoreductive surgery and responsive chemotherapy. Overestimating an

    Advanced renal cell carcinoma was treated by transcatheter embolization with radioactive seeds. There were 14 patients with nonresectable or metastatic disease (stage IV) and 8 with stage II tumors treated. In 8 patients the tumor was implanted with radon seeds, complemented by 2,500 rad of external beam therapy, and 10 were treated by embolization with 125iodine seeds. The total dose delivered ranged form 1,600 to 14,000 rad. Several patients also had intra-arterial chemotherapy. Survival was improved over previously reported studies: 13 of 22 (59 per cent) at risk for 2 years and 5 of 15 (33 per cent) for 5 years. Distant metastases did not resolve but significant local palliation was achieved. Tumor size decreased in all patients, 8 of whom subsequently underwent nephrectomy. Other local effects included pain control (10 per cent), weight gain (75 per cent) and control of hemorrhage (88 per cent). Toxicity was minimal and consisted of mild nausea or pain. This approach, using a low energy emitter, allows selective high dose radiation of the tumor, while sparing the adjacent normal tissues. In contrast to renal artery occlusion with inert embolic material, subsequent nephrectomy in patients with disseminated disease is not necessary. Transcatheter embolization with radioactive seeds should be considered a reasonable palliative procedure in patients with nonresectable primary renal cell carcinoma.

    To examine the impact of anatomic structure-based image sets in deformable image registration (DIR) for cervical cancer patients. CT examinations of 7 patients previously treated for locally advanced cervical cancer with external beam radiation therapy and from three to five fractions of high-dose-rate brachytherapy (HDR-BT) were used. Structure-based image sets were created from "free" structures already made for planning purposes, with each structure of interest assigned a unique, homogeneous Hounsfield number. Subsequent HDR fractions were registered to the pretreatment external beam radiation therapy and/or the first HDR fraction using commercially available software by rigid alignment (RIG) followed by DIR. Comparison methods included quantification of external contour displacement between source and target images and calculation of mean voxel displacement values. Registration results for structure-based image sets were then compared and contrasted to intensity-based registrations of the original grayscale images. Utilization of anatomic structure-based image sets resulted in better initial rigid matching (A-RIG) with more importance on applicator positioning and soft tissue structures. Subsequent DIR of anatomic structure-based images allowed for intermodality registrations, whereas all intermodality registrations using original CT images failed to produce anatomically feasible results. We have investigated the use of structure-based CT image sets for image registrations and have produced anatomically favorable registrations with excellent matching of external contours as compared to registrations of original grayscale images. Commercial software registrations using treatment-planning structures required no manual tweaking on a per-patient basis, suggesting results are reproducible and broadly applicable.

    Background New chemotherapy combinations are being tested for the treatment of women with advanced, persistent or recurrent cervical cancer. We sought to evaluate the cost effectiveness of some newer combination therapies in cervical cancer. Patients and methods A cost effectiveness decision model was used to analyze Gynecologic Oncology Group 240. All regimens were modeled for seven cycles. The regimens studied are as follows: regimen 1, cisplatin/paclitaxel (CP); regimen 2, CP with bevacizumab (CP+B); regimen 3, paclitaxel/topotecan (PT); and regimen 4, PT with bevacizumab (PT+B). Overall survival, cost, and complications were studied. Sensitivity analyses were performed. Results Mean chemotherapy costs over mean total costs for seven cycles of each follows: CP $571/$32,966; CP+B $61,671/$96,842; PT $9,211/$71,620; and PT+B $70,312/$109,211. Incremental cost-effectiveness ratio (ICER) for CP+B was $133,559/quality adjusted life year (QALY). ICER for PT+B was $124,576/QALY. To achieve an incremental ICER for CP+B:CP of <$50,000/QALY gained, the mean overall survival has to increase from 1.1 years with CP to 3.5 years with CP+B. An ICER <$50,000/QALY for the other regimens would take a survival of >10 years for PT and 4.1 years for PT+B. Treating 1,000 women with cervical cancer with CP+B would cost almost double the cost of treating >18,000 women with ovarian cancer annually (carboplatin/paclitaxel). Conclusion CP is the most cost effective regimen. A 12-month increase in overall survival will not even make the newer combinations cost effective. Currently, the use of bevacizumab is not sustainable at today’s costs. PMID:27382318

    Image-guided tumor ablation for early stage hepatocellular carcinoma (HCC) is an accepted non-surgical treatment that provides excellent local tumor control and favorable survival benefit. This review summarizes the recent advances in tumor ablation for HCC. Diagnostic imaging and molecular biology of HCC has recently undergone marked improvements. Second-generation ultrasonography (US) contrast agents, new computed tomography (CT) techniques, and liver-specific contrast agents for magnetic resonance imaging (MRI) have enabled the early detection of smaller and inconspicuous HCC lesions. Various imaging-guidance tools that incorporate imaging-fusion between real-time US and CT/MRI, that are now common for percutaneous tumor ablation, have increased operator confidence in the accurate targeting of technically difficult tumors. In addition to radiofrequency ablation (RFA), various therapeutic modalities including microwave ablation, irreversible electroporation, and high-intensity focused ultrasound ablation have attracted attention as alternative energy sources for effective locoregional treatment of HCC. In addition, combined treatment with RFA and chemoembolization or molecular agents may be able to overcome the limitation of advanced or large tumors. Finally, understanding of the biological mechanisms and advances in therapy associated with tumor ablation will be important for successful tumor control. All these advances in tumor ablation for HCC will result in significant improvement in the prognosis of HCC patients. In this review, we primarily focus on recent advances in molecular tumor biology, diagnosis, imaging-guidance tools, and therapeutic modalities, and refer to the current status and future perspectives for tumor ablation for HCC.

    The oral cavity is the most common site of head and neck squamous cell carcinoma, a disease which results in significant morbidity and mortality worldwide. Though the primary modality of treatment for patients with oral cavity cancer remains surgical resection, many patients present with advanced disease and are thus treated using a multi-disciplinary approach. Patients with extracapsular spread of lymphatic metastasis and surgical margins that remain positive have been found to be at high risk for local-regional recurrence and death from disease, and are most often recommended to receive both post-operative radiation as well as systemic chemotherapy. The basis for this approach, as well as scientific developments that underly future trials of novels treatments for patients with high-risk oral cavity cancer are reviewed. PMID:21461056

    2015-01-01

    Basal cell carcinoma (BCC), a malignant neoplasm derived from non-keratinizing cells that originate in the basal layer of the epidermis, is the most common cancer in humans. Several factors such as anatomic location, histologic features, primary or recurrent tumors, and patient characteristics influence the choice of treatment modality for BCC. Mohs micrographic surgery (MMS) facilitates optimal margin control and conservation of normal tissue for the management of BCC; however, other treatment modalities may also be implemented in the correct clinical scenario. Other treatment modalities that will be reviewed include simple excision, electrodesiccation and curettage, cryotherapy, topical immunotherapy and chemotherapy, photodynamic therapy, and radiation therapy. In addition, targeted molecular therapeutic options for the treatment of advanced or metastatic BCC will be discussed in this informal review based on recent literature obtained by using PubMed with relevant search terms.

    Treatment of advanced hepatocellular carcinoma (HCC) has reached a plateau after the approval of sorafenib in 2007. Several molecularly targeted therapies have failed to show significant improvement in survival outcomes compared with sorafenib, due to flaws in the design of clinical trials or failure to understand and correct for the competing co-morbidity of liver dysfunction. Lenvatinib is a multitargeted tyrosine kinase inhibitor with potent antiangiogenic effects, and has recently been approved for differentiated thyroid cancer. Lenvatinib has shown highly promising response data in Phase I/II clinical trials in HCC, although with some concerns regarding its toxicity profile. The pivotal Phase III REFLECT trial comparing lenvatinib to sorafenib has been completed, and the results of this trial will determine whether lenvatinib represents a breakthrough in the current crisis affecting HCC drug development.

    Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma in vitro. In a phase II trial, we investigated safety and efficacy including selection criteria for best response in advanced or metastasised hepatocellular carcinoma. Methods 44 patients (84 % male, median age 69 years) not suitable or refractory to conventional therapy received thymostimulin 75 mg subcutaneously five times per week for a median of 8.2 months until progression or complete response. 3/44 patients were secondarily accessible to local ablation or chemoembolisation. Primary endpoint was overall survival, secondary endpoint tumor response or progression-free survival. A multivariate Cox's regression model was used to identify variables affecting survival. Results Median survival was 11.5 months (95% CI 7.9–15.0) with a 1-, 2- and 3-year survival of 50%, 23% and 9%. In the univariate analysis, a low Child-Pugh-score (p = 0.01), a low score in the Okuda- and CLIP-classification (p < 0.001) or a low AFP-level (p < 0.001) were associated with better survival, but not therapy modalities other than thymostimulin (p = 0.1) or signs of an invasive HCC phenotype such as vascular invasion (p = 0.3) and metastases (p = 0.1). The only variables independently related to survival in the Cox's regression model were Okuda stage and presence of liver cirrhosis (p < 0.01) as well as response to thymostimulin (p < 0.05). Of 39/44 patients evaluable for response, two obtained complete responses (one after concomitant radiofrequency ablation), five partial responses (objective response 18%), twenty-four stable disease (tumor control rate 79%) and eight progressed. Median progression-free survival was 6.4 months (95% CI 0.8–12). Grade 1 local reactions following injection were the only side effects. Conclusion Outcome in our study rather depended on liver function and intrahepatic tumor growth (presence of liver cirrhosis and Okuda stage) in addition

    To evaluate the long-term results of continuous infusion intra-arterial 5-fluorouracil (CI IA 5-FU) given with concurrent pelvic radiotherapy (RT) for FIGO stage IIIB-IVA carcinoma of the cervix. Between 1965 and 1974, 27 patients with extensive FIGO Stage IIIB (22 patients) or Stage IVA (5 patients) squamous cell carcinoma of the cervix were treated with CI IA 5-FU and RT. Twenty-one patients (78%) had bilateral pelvic wall involvement, 25 (93%) had massive tumors (> or =8 cm in diameter), 7 (27%) had involvement of the lower one-third of the vagina, and 15 (56%) presented with hydronephrosis. All patients underwent routine clinical staging, transperitoneal para-aortic lymph node dissection, and bilateral hypogastric artery catheter placement. 5-FU was continuously infused at a dose rate of 10 mg/kg/day on Days 1-15 of RT. The median dose of 5-FU was 376 mg/m2/day (range 270-692). All patients received concurrent pelvic RT to a median dose of 50 Gy at 2.0 Gy per fraction. Only 4 patients received intracavitary RT. The median follow-up of surviving patients was 190 months. The overall 5-year survival rate was 37%. For the 22 patients with FIGO Stage IIIB disease, the 5-year survival rate was 41%. The survival rate for 18 patients treated with only external beam radiation and chemotherapy for Stage IIIB disease was 33%. Four of 10 patients treated with only 50 Gy of external beam radiation and CI IA 5-FU were long-term survivors. Acute complications, including hematologic toxicity and skin reactions, were severe, with 1 death from neutropenic sepsis. Severe late complications were only observed in patients treated with > or =60 Gy of external beam radiation. While this series is small, the fact that 4 patients with massive Stage IIIB tumors survived after a total radiation dose of only 50 Gy suggests that RT with CI IA 5-FU deserves further study. Modifications in dose, technique, and route of administration should reduce toxicity, and the addition of intracavitary

    The present study aims to investigate the expression levels of two critical mammalian target of rapamycin (mTOR) downstream effectors, 4E binding protein 1 (4EBP1) and eukaryotic initiation factor 4E (eIF4E) proteins, in precancerous squamous intraepithelial lesions and cancer of the uterine cervix, and their association with human papilloma virus (HPV) infection status. Uterine cervical biopsies from 73 patients were obtained, including 40 fresh-frozen samples and 42 archival formalin-fixed, paraffin-embedded tissue specimens. Whole protein extracts were analyzed for the expression of 4EBP1 and eIF4E proteins using western blotting. In addition, distribution of 4EBP1 and eIF4E protein expression and 4EBP1 phosphorylation (P-4EBP1) were analyzed by immunohistochemistry in archival tissues and correlated with the degree of dysplasia. The presence of high-risk HPV (HR-HPV) types was assessed by polymerase chain reaction. Using western blot analysis, high expression levels of 4EBP1 and eIF4E were observed in all uterine cervical carcinomas, which significantly correlated with the degree of dysplasia. By immunohistochemistry, overexpression of 4EBP1 and eIF4E was detected in 20 of 21 (95%) and 17 of 21 (81%) samples, respectively, in patients with high-grade dysplasia and carcinomas, compared with 1 of 20 (5%) and 2 of 20 (10%) samples, respectively, in patients with low-grade lesions or normal histology. All 4EBP1-positive cases tested were also positive for P-4EBP1. Furthermore, overexpression of 4EBP1 and eIF4E significantly correlated with the presence of HR-HPV oncogenic types. The present study demonstrated that critical effectors of mTOR signaling, which control protein synthesis initiation, are overexpressed in cervical high-grade dysplasia and cancer, and their levels correlate with oncogenic HPV types. These findings may provide novel targets for investigational therapeutic approaches in patients with cancer of the uterine cervix. PMID:27899988

    BACKGROUND Alterations in hedgehog signaling are implicated in the pathogenesis of basal-cell carcinoma. Although most basal-cell carcinomas are treated surgically, no effective therapy exists for locally advanced or metastatic basal-cell carcinoma. A phase 1 study of vismodegib (GDC-0449), a first-in-class, small-molecule inhibitor of the hedgehog pathway, showed a 58% response rate among patients with advanced basal-cell carcinoma. METHODS In this multicenter, international, two-cohort, nonrandomized study, we enrolled patients with metastatic basal-cell carcinoma and those with locally advanced basal-cell carcinoma who had inoperable disease or for whom surgery was inappropriate (because of multiple recurrences and a low likelihood of surgical cure, or substantial anticipated disfigurement). All patients received 150 mg of oral vismodegib daily. The primary end point was the independently assessed objective response rate; the primary hypotheses were that the response rate would be greater than 20% for patients with locally advanced basal-cell carcinoma and greater than 10% for those with metastatic basal-cell carcinoma. RESULTS In 33 patients with metastatic basal-cell carcinoma, the independently assessed response rate was 30% (95% confidence interval [CI], 16 to 48; P = 0.001). In 63 patients with locally advanced basal-cell carcinoma, the independently assessed response rate was 43% (95% CI, 31 to 56; P<0.001), with complete responses in 13 patients (21%). The median duration of response was 7.6 months in both cohorts. Adverse events occurring in more than 30% of patients were muscle spasms, alopecia, dysgeusia (taste disturbance), weight loss, and fatigue. Serious adverse events were reported in 25% of patients; seven deaths due to adverse events were noted. CONCLUSIONS Vismodegib is associated with tumor responses in patients with locally advanced or metastatic basal-cell carcinoma.

    Despite offering significant clinical benefits in advanced renal-cell carcinoma (RCC), the effectiveness of targeted therapies eventually declines with the development of resistance. Defining optimal sequences of therapy is therefore the focus of much current research. There is also evidence that treatment 're-challenge' may be an effective strategy in some patients. We review evidence to evaluate whether sunitinib may have value as re-challenge therapy in patients who have progressed on prior targeted therapy with sunitinib and/or an alternative tyrosine kinase inhibitor or mammalian target of rapamycin inhibitor. Re-challenge with sunitinib appears to be of clinical benefit, thus representing a feasible therapeutic option for patients with advanced RCC who are refractory to other treatments and are able to receive further therapy. These observations support hypotheses that resistance to targeted agents is transient and can be at least partially reversed by re-introduction of the same agent after a treatment break. Median progression-free survival durations appear to be shorter and response rates lower on re-challenge than following initial treatment, although a wider interval between treatments appears to increase response to sunitinib re-challenge.

    Hepatocellular carcinoma (HCC) remains a common and lethal malignancy worldwide and arises in the setting of a host of diseases. The incidence continues to increase despite multiple vaccines and therapies for viruses such as the hepatitis B and C viruses. In addition, due to the growing incidence of obesity in Western society, there is anticipation that there will be a growing population with HCC due to non-alcoholic fatty liver disease. Due to the growing frequency of this disease, screening is recommended using ultrasound with further imaging using magnetic resonance imaging and multi-detector computed tomography used for further characterization of masses. Great advances have been made to help with the early diagnosis of small lesions leading to potential curative resection or transplantation. Resection and transplantation maybe used in a variety of patients that are carefully selected based on underlying liver disease. Using certain guidelines and clinical acumen patients may have good outcomes with either resection or transplantation however many patients are inoperable at time of presentation. Fortunately, the use of new locoregional therapies has made down staging patients a potential option making them potential surgical candidates. Despite a growing population with HCC, new advances in viral therapies, chemotherapeutics, and an expanding population of surgical and transplant candidates might all contribute to improved long-term survival of these patients.

    Rarely, basal cell carcinomas (BCCs) have the potential to become extensively invasive and destructive, a phenomenon that has led to the term "locally advanced BCC" (laBCC). We identified and described the diverse settings that could be considered "locally advanced". The panel of experts included oncodermatologists, dermatological and maxillofacial surgeons, pathologists, radiotherapists and geriatricians. During a 1-day workshop session, an interactive flow/sequence of questions and inputs was debated. Discussion of nine cases permitted us to approach consensus concerning what constitutes laBCC. The expert panel retained three major components for the complete assessment of laBCC cases: factors of complexity related to the tumour itself, factors related to the operability and the technical procedure, and factors related to the patient. Competing risks of death should be precisely identified. To ensure homogeneous multidisciplinary team (MDT) decisions in different clinical settings, the panel aimed to develop a practical tool based on the three components. The grid presented is not a definitive tool, but rather, it is a method for analysing the complexity of laBCC.

    AIMS: To evaluate the predictive value of the nuclear DNA content (image cytometry) and p53 overexpression (immuno-histochemistry using antibody CM-1) in uniformly treated stage I carcinomas of the mobile tongue. Also, to compare stage I carcinomas with advanced tongue carcinomas (stages II-IV). METHODS: Archival formalin fixed, paraffin wax embedded tumour specimens from 54 patients with stage I squamous cell carcinoma and 37 patients with advanced squamous cell carcinoma were analysed. Mean follow up time of the stage I carcinomas was 71 months (median, 62.5; range, 6-175). RESULTS: Twenty three patients (stage I) had recurring disease: 10 had local recurrence (in the tongue) and 13 had regional recurrence (cervical metastases). Locally recurring stage I carcinomas had a more pronounced DNA deviation than the other stage I carcinomas and this degree of deviation was comparable with the DNA content of advanced carcinomas. Stage I carcinomas that developed regional recurrences overexpressed p53 more frequently. In Cox multivariate regression analysis of time to recurrence, DNA deviation was a significant parameter in tumours that recurred locally (p = 0.032). p53 overexpression was the only parameter close to significance for regional recurrence (p = 0.065). CONCLUSIONS: Nuclear DNA content and p53 immunostaining are of value for the prediction of recurrence of stage I squamous cell carcinomas of the mobile tongue. Stage I tongue carcinomas that are prone to local recurrence show the same DNA content as do advanced tongue carcinomas. PMID:10193521

    The purpose of this study was to evaluate the efficacy and toxicity of docetaxel as single-agent neoadjuvant chemotherapy in locoregionally advanced cervical carcinoma. Between April 1998 and August 2000, 38 untreated patients with International Federation of Gynecology and Obstetrics stages IIB to IVA were entered onto this study. The median age was 44 years (range: 25-66 years). Stages: IIB 22 patients, IIIB 15 patients, and IVA 1 pt. Treatment consisted of docetaxel 100 mg/m2 IV infusion during 1 hour. Standard premedication with dexamethasone, diphenhydramine, and ranitidine was used. Cycles were repeated every 3 weeks for three courses, followed by radical surgery when it was judged appropriate, or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. 106 cycles of therapy were administered; all patients were evaluable for TX, whereas 35 were evaluable for response (3 patients refused further treatment after the first cycle of therapy). Complete response (CR): 1 patient (3%); partial response: 11 patients (31%), for an overall objective response rate of 34% (95% CI: 15-53%); no change (NC): 16 patients (46%); and progressive disease: 7 patients (20%). Six patients (17%) underwent surgery and a pathologic CR was confirmed in 1 of them. The median time to treatment failure and the median survival have not been reached yet. The limiting toxicity was leukopenia in 25 patients (69%) (G1-G2: 14 patients, G3: 10 patients, and G4: 1 patient). Neutropenia: 28 patients (78%) (G1-G2: 10 patients, G3: 8 and G4: 10). Myalgias: 17 patients (47%) (G1-G2: 15 patients and G3: 2 patients). Emesis: 21 patients (55%) (G1-G2: 19 patients and G3: 2 patients). Alopecia G3: 13 patients (36%); rash cutaneous 26 patients (68%) (G1-G2: 22 patients and G3: 4 patients). There were no hypersensitivity reactions or fluid-retention syndrome.

    Management options are limited for patients with radioactive iodine refractory, locally advanced, or metastatic differentiated thyroid carcinoma. Prior to 2015, sorafenib, a multitargeted tyrosine kinase inhibitor, was the only approved treatment and was associated with a median progression-free survival (PFS) of 11 months and overall response rate (ORR) of 12% in a phase III trial. Lenvatinib, a multikinase inhibitor with high potency against VEGFR and FGFR demonstrated encouraging results in phase II trials. Recently, the pivotal SELECT trial provided the basis for the FDA approval of lenvatinib as a second targeted therapy for these patients. Median PFS of 18.3 months in the lenvatinib group was significantly improved from 3.6 months in the placebo group, with an HR of 0.21 (95% confidence interval, 0.4-0.31; P < 0.0001). ORR was also significantly increased in the lenvatinib arm (64.7%) compared with placebo (1.5%). In this article, we will review the molecular mechanisms of lenvatinib, the data from preclinical studies to the recent phase III clinical trial, and the biomarkers being studied to further guide patient selection and predict treatment response.

    Purpose: The local failure rate in patients with locoregionally advanced cervical cancer is 41-72% after radiotherapy (RT) alone, whereas local control is a prerequisite for cure. The Dutch Deep Hyperthermia Trial showed that combining RT with hyperthermia (HT) improved 3-year local control rates of 41-61%, as we reported earlier. In this study, we evaluate long-term results of the Dutch Deep Hyperthermia Trial after 12 years of follow-up. Methods and Materials: From 1990 to 1996, a total of 114 women with locoregionally advanced cervical carcinoma were randomly assigned to RT or RT + HT. The RT was applied to a median total dose of 68 Gy. The HT was given once weekly. The primary end point was local control. Secondary end points were overall survival and late toxicity. Results: At the 12-year follow-up, local control remained better in the RT + HT group (37% vs. 56%; p = 0.01). Survival was persistently better after 12 years: 20% (RT) and 37% (RT + HT; p = 0.03). World Health Organization (WHO) performance status was a significant prognostic factor for local control. The WHO performance status, International Federation of Gynaecology and Obstetrics (FIGO) stage, and tumor diameter were significant for survival. The benefit of HT remained significant after correction for these factors. European Organization for Research and Treatment of Cancer Grade 3 or higher radiation-induced late toxicities were similar in both groups. Conclusions: For locoregionally advanced cervical cancer, the addition of HT to RT resulted in long-term major improvement in local control and survival without increasing late toxicity. This combined treatment should be considered for patients who are unfit to receive chemotherapy. For other patients, the optimal treatment strategy is the subject of ongoing research.

    Transmission of radiation fluence through patient's body has a correlation to the planned target dose. A method to estimate the delivered dose to target volumes was standardized using a beam level 0.6 cc ionization chamber (IC) positioned at electronic portal imaging device (EPID) plane from the measured transit signal (St) in patients with cancer of uterine cervix treated with three-dimensional conformal radiotherapy (3DCRT). The IC with buildup cap was mounted on linear accelerator EPID frame with fixed source to chamber distance of 146.3 cm, using a locally fabricated mount. Sts were obtained for different water phantom thicknesses and radiation field sizes which were then used to generate a calibration table against calculated midplane doses at isocenter (Diso,TPS), derived from the treatment planning system. A code was developed using MATLAB software which was used to estimate the in vivo dose at isocenter (Diso,Transit) from the measured Sts. A locally fabricated pelvic phantom validated the estimations of Diso,Transit before implementing this method on actual patients. On-line dose estimations were made (3 times during treatment for each patient) in 24 patients. The Diso,Transit agreement with Diso,TPS in phantom was within 1.7% and the mean percentage deviation with standard deviation is −1.37% ±2.03% (n = 72) observed in patients. Estimated in vivo dose at isocenter with this method provides a good agreement with planned ones which can be implemented as part of quality assurance in pelvic sites treated with simple techniques, for example, 3DCRT where there is a need for documentation of planned dose delivery.

    Diverse chemokines and their receptors have been associated with tumor growth, tumor dissemination, and local immune escape. In different tumor entities, the level of chemokine receptor CXCR4 expression has been linked with tumor progression and decreased survival. The aim of this study was to evaluate the influence of CXCR4 expression on the progression of human renal cell carcinoma. CXCR4 expression of renal cell carcinoma was assessed by immunohistochemistry in 113 patients. Intensity of CXCR4 expression was correlated with both tumor and patient characteristics. Human renal cell carcinoma revealed variable intensities of CXCR4 expression. Strong CXCR4 expression of renal cell carcinoma was significantly associated with advanced T-status (P = .039), tumor dedifferentiation (P = .0005), and low hemoglobin (P = .039). In summary, strong CXCR4 expression was significantly associated with advanced dedifferentiated renal cell carcinoma. PMID:19266088

    AIM: To investigate the safety and efficacy of the Cyberknife treatment for patients with advanced or terminal stage hepatocellular carcinoma (HCC). METHODS: Patients with HCC with extrahepatic metastasis or vascular or bile duct invasion were enrolled between May 2011 and June 2015. The Cyberknife was used to treat each lesion. Treatment response scores were based on Response Evaluation Criteria in Solid Tumors v1.1. The trends of tumor markers, including alpha fetoprotein (AFP) and proteins induced by vitamin K absence II (PIVKA II) were assessed. Prognostic factors for tumor response and tumor markers were evaluated with Fisher’s exact test and a logistic regression model. Survival was evaluated with the Kaplan-Meier method and multivariate analysis was performed using the Cox proportional hazards model. RESULTS: Sixty-five patients with 95 lesions were enrolled. Based on the Barcelona Clinic Liver Cancer classification, all patients were either in the advanced or terminal stage of the disease. The target lesions were as follows: 52 were bone metastasis; 9, lung metastasis; 7, brain metastasis; 9, portal vein invasion; 4, hepatic vein invasion; 4, bile duct invasion; and 10 other lesion types. The response rate and disease control rate were 34% and 53%, respectively. None of the clinical factors correlated significantly with tumor response. Fiducial marker implantation was associated with better control of both AFP (HR = 0.152; 95%CI: 0.026-0.887; P = 0.036) and PIVKA II (HR = 0.035; 95%CI: 0.003-0.342; P = 0.004). The median survival time was 9 mo (95%CI: 5-15 mo). Terminal stage disease (HR = 9.809; 95%CI: 2.589-37.17, P < 0.001) and an AFP of more than 400 ng/mL (HR = 2.548; 95%CI: 1.070-6.068, P = 0.035) were associated with worse survival. A radiation dose higher than 30 Gy (HR = 0.274; 95%CI: 0.093-0.7541, P = 0.012) was associated with better survival. In the 52 cases of bone metastasis, 36 patients (69%) achieved pain relief.

    Tissue hypoxia is a characteristic property of cervical cancers that makes tumors resistant to chemo- and radiation therapy. Erythropoietin (Epo) is a hypoxia-inducible stimulator of erythropoiesis. Acting via its receptor (EpoR), Epo up-regulates bcl-2 and inhibits apoptosis of erythroid cells and rescues neurons from hypoxic damage. In addition to human papillomavirus infection, increased bcl-2 expression and decreased apoptosis are thought to play a role in the progression of cervical neoplasia. Using reverse transcriptase-polymerase chain reaction and Western blotting we showed that HeLa and SiHa cervical carcinoma cells and human cervical carcinomas express EpoR, and that hypoxia enhances EpoR expression. Exogenous Epo stimulated tyrosine phosphorylation and inhibited the cytotoxic effect of cisplatin in HeLa cervical carcinoma cells. Using immunohistochemistry, we examined the expression of Epo, EpoR, p16, hypoxia-inducible factor (HIF)-1α, and bcl-2 in benign and dysplastic cervical squamous epithelia and invasive squamous cell carcinomas (ISCCs). EpoR expression in benign epithelia was confined to the basal cell layers, whereas in dysplasias it increasingly appeared in more superficial cell layers and showed a significant correlation with severity of dysplasia. Diffuse EpoR expression was found in all ISCCs. Expression of Epo and HIF-1α was increased in dysplasias compared to benign epithelia. Focal Epo and HIF-1α expression was seen near necrotic areas in ISCCs, and showed correlation in their spatial distribution. Significant correlation was found between expression of EpoR, and p16 and bcl-2 in benign and dysplastic squamous epithelia. Our results suggest that increased expression of Epo and EpoR may play a significant role in cervical carcinogenesis and tumor progression. Hypoxia-inducible Epo signaling may play a significant role in the aggressive behavior and treatment resistance of hypoxic cervical cancers. PMID:12759237

    Purpose: To evaluate toxicity, local tumor control, and survival after preoperative chemoradiation for operable bulky cervical carcinoma. Methods and Materials: Between December 1991 and July 2006, 92 patients with operable bulky stage IB2, IIA, and IIB cervical carcinoma without pelvic or para-aortic nodes on pretreatment imaging were treated. Treatment consisted of preoperative external beam pelvic radiation therapy (EBRT) and concomitant chemotherapy (CT) during the first and fourth weeks of radiation combining 5-fluorouracil and cisplatin. The pelvic radiation dose was 40.5 Gy over 4.5 weeks. EBRT was followed by low-dose rate uterovaginal brachytherapy with a total dose of 20 Gy in 62 patients. After a median rest period of 44 days, all patients underwent Class II modified radical hysterectomy with bilateral pelvic lymphadenectomy. Thirty patients who had not received preoperative uterovaginal brachytherapy underwent postoperative low-dose-rate vaginal brachytherapy at a dose of 20 Gy. The mean follow-up was 46 months. Results: Pathologic residual tumor was observed in 43 patients. After multivariate analysis, additional preoperative uterovaginal brachytherapy was the single significant predictive factor for pathologic complete response rate (p = 0.019). The 2- and 5-year disease-free survival (DFS) rates were 80.4% and 72.2%, respectively. Pathologic residual cervical tumor was the single independent factor decreasing the probability of DFS (p = 0.020). Acute toxicities were moderate. Two severe ureteral complications requiring surgical intervention were observed. Conclusions: Concomitant chemoradiation followed by surgery for operable bulky stage I-II cervical carcinoma without clinical lymph node involvement can be used with acceptable toxicity. Pathologic complete response increases the probability of DFS.

    Aim—To test the hypothesis that, because the human papillomavirus (HPV) E2 protein represses viral early gene transcription, E2 gene sequence variation or disruption could play a part in the induction of the numerical chromosome abnormalities that have been described in squamous cervical lesions. Methods—The integrity and sequence of the E2 gene from 11 cervical intraepithelial neoplasia (CIN) grade 3 lesions and 14 invasive squamous cell carcinomas, all of which contained HPV-16, were analysed by the polymerase chain reaction (PCR). The E2 gene was amplified in three overlapping fragments and PCR products sequenced directly. Chromosome abnormalities were identified by interphase cytogenetics using chromosome specific probes for chromosomes 1, 3, 11, 17, 18, and X. Results—E2 gene disruption was present in significantly more invasive carcinomas (eight of 14) than CIN 3 lesions (one of 11) (p = 0.03). No association was found between E2 disruption and the presence of a numerical chromosome abnormality. The E2 gene from the non-disrupted isolates was sequenced and wild-type (n = 5) and variant (n = 11) sequences identified. Variant sequences belonged to European and African classes and contained from one to 15 amino acid substitutions. Although numerical chromosome abnormalities were significantly more frequent in invasive squamous cell carcinoma than CIN 3 (p = 0.04), there was no significant relation between the presence of sequence variation and either histological diagnosis or chromosome abnormality. Conclusions—These data do not support the hypothesis that E2 gene disruption or variation is important in the induction of chromosome imbalance in these lesions. However, there is a relation between E2 gene disruption and the presence of invasive disease. PMID:11040943

    Abstract Primary urethral carcinoma (PUC) is a rare and aggressive cancer, often underdetected and consequently unsatisfactorily treated. We report a case of advanced PUC, surgically treated with combined approaches. A 47-year-old man underwent transurethral resection of a urethral lesion with histological evidence of a poorly differentiated squamous cancer of the bulbomembranous urethra. Computed tomography (CT) and bone scans excluded metastatic spread of the disease but showed involvement of both corpora cavernosa (cT3N0M0). A radical surgical approach was advised, but the patient refused this and opted for chemotherapy. After 17 months the patient was referred to our department due to the evidence of a fistula in the scrotal area. CT scan showed bilateral metastatic disease in the inguinal, external iliac, and obturator lymph nodes as well as the involvement of both corpora cavernosa. Additionally, a fistula originating from the right corpus cavernosum extended to the scrotal skin. At this stage, the patient accepted the surgical treatment, consisting of different phases. Phase I: Radical extraperitoneal cystoprostatectomy with iliac-obturator lymph nodes dissection. Phase II: Creation of a urinary diversion through a Bricker ileal conduit. Phase III: Repositioning of the patient in lithotomic position for an overturned Y skin incision, total penectomy, fistula excision, and “en bloc” removal of surgical specimens including the bladder, through the perineal breach. Phase IV: Right inguinal lymphadenectomy. The procedure lasted 9-and-a-half hours, was complication-free, and intraoperative blood loss was 600 mL. The patient was discharged 8 days after surgery. Pathological examination documented a T4N2M0 tumor. The clinical situation was stable during the first 3 months postoperatively but then metastatic spread occurred, not responsive to adjuvant chemotherapy, which led to the patient's death 6 months after surgery.

    Thirty-seven patients with invasive cervical cancer have been referred to the Department of Radiation Oncology at the University of Washington following radical hysterectomy and pelvic lymphadenectomy. Patients at high-risk for tumor recurrence were selected for adjuvant pelvic irradiation because of adverse risk factors identified on pathological study of the hysterectomy specimen. All patients were treated because of possible residual, microscopic carcinoma. Fourteen patients (38%) developed recurrent cancer, of whom 10 (27%) manifested initial failure within the irradiated volume. Possible explanations for this observation are discussed.

    The purpose of this study was to evaluate the toxicity and efficacy of twice-daily external irradiation to the pelvis and para-aortics with brachytherapy and concurrent chemotherapy for carcinoma of the cervix with positive para-aortic lymph nodes. This study was designed to administer twice-daily radiation doses of 1.2 Gy to the pelvis and para-aortics at 4- to 6-h intervals, 5 days per week. The total external radiation doses were 24 to 48 Gy to the whole pelvis, 12 to 36 Gy parametrial boost, and 48 Gy to the para-aortics with an additional boost to a total dose of 54 to 58 Gy to the known metastatic para-aortic site. One or two intracavitary applications were performed to deliver a total minimum dose of 85 Gy to point A. Cisplatin (75 mg/m2, days 1 and 22) and 5-FU (1000 mg/m2/24 h x 4 days; days 1 and 22) were given for two or three cycles. Twenty-nine patients with clinical Stages I to IV carcinoma of the cervix with biopsy-proven para-aortic lymph nodes were enrolled in this study. Hyperfractionated external radiotherapy was completed in 86% (25 of 29). Brachytherapy was given in two applications to 48% (14 of 29), 31% (9 of 29) had one intracavitary application, 14% (4 of 29) had no brachytherapy, one had three applications, and one had five HDR applications. Radiotherapy was completed per protocol in 69%. Three courses of chemotherapy were given to 24% (7 of 29), 72% (21 of 29) received two courses, and one patient did not receive chemotherapy. The acute toxicity from chemotherapy was Grade 1 in 3%, Grade 2 in 17%, Grade 3 in 48%, and Grade 4 in 28%. Radiotherapy toxicity was Grade 1 in 7%, Grade 2 in 34%, Grade 3 in 21%, and Grade 4 in 28%. One Grade 5 toxicity occurred and the patient died from a myocardial infarction from chemotherapy and radiotherapy colitis during her course of therapy. The median follow-up time was 18.9 months. The overall survival estimates were 59% at 1 year and 47% at 2 years. The probability of local-regional failure was 38% at 1

    Purpose: To more accurately define clinical target volume for cervical cancer radiation treatment planning by evaluating tumor microscopic extension toward the uterus body (METU) in International Federation of Gynecology and Obstetrics stage Ib-IIa squamous cell carcinoma of the cervix (SCCC). Patients and Methods: In this multicenter study, surgical resection specimens from 318 cases of stage Ib-IIa SCCC that underwent radical hysterectomy were included. Patients who had undergone preoperative chemotherapy, radiation, or both were excluded from this study. Microscopic extension of primary tumor toward the uterus body was measured. The association between other pathologic factors and METU was analyzed. Results: Microscopic extension toward the uterus body was not common, with only 12.3% of patients (39 of 318) demonstrating METU. The mean (±SD) distance of METU was 0.32 ± 1.079 mm (range, 0-10 mm). Lymphovascular space invasion was associated with METU distance and occurrence rate. A margin of 5 mm added to gross tumor would adequately cover 99.4% and 99% of the METU in the whole group and in patients with lymphovascular space invasion, respectively. Conclusion: According to our analysis of 318 SCCC specimens for METU, using a 5-mm gross tumor volume to clinical target volume margin in the direction of the uterus should be adequate for International Federation of Gynecology and Obstetrics stage Ib-IIa SCCC. Considering the discrepancy between imaging and pathologic methods in determining gross tumor volume extent, we recommend a safer 10-mm margin in the uterine direction as the standard for clinical practice when using MRI for contouring tumor volume.

    Vismodegib is a Hedgehog signaling pathway inhibitor recently approved by the US Food and Drug Administration for advanced basal cell carcinoma. We present 2 cases of clinically significant squamous cell carcinoma within the tumor bed of locally advanced basal cell carcinoma found during vismodegib treatment. The first case is that of a patient with locally advanced basal cell carcinoma responsive to vismodegib but with an enlarging papule within the tumor bed. On biopsy, this papule was an invasive acantholytic squamous cell carcinoma. The second case is that of a patient with Gorlin syndrome with a locally advanced basal cell carcinoma that was stable while the patient was receiving therapy with vismodegib for 2.5 years but subsequently increased in size. Biopsy specimens from this tumor showed invasive squamous cell carcinoma, spindle cell subtype. In both cases, the squamous cell carcinomas were surgically resected. These cases highlight the importance of repeated biopsy in locally advanced basal cell carcinomas in 2 clinical situations: (1) when an area within the tumor responds differentially to vismodegib, and (2) when a tumor stops being suppressed by vismodegib. Timely diagnosis of non-basal cell histologic characteristics is critical to institution of effective therapy.

    Renal cell carcinoma (RCC) is the 10th most common cancer in Western countries. The prognosis of metastatic disease is unfavorable but may be different according to several risk factors, such as histology and clinical features (Karnofsky performance status, time from nephrectomy, hemoglobin level, neutrophils and thrombocytes count, lactate dehydrogenase and calcium serum value, sites and extension of the disease). In this review, we focused on some recent developments in the use of immunotherapy, surgery and cryotherapy in the treatment of advanced disease. While RCC is unresponsive to chemotherapy, recent advances have emerged with the development of targeted agents and innovative immunotherapy-based treatments. Surgical resection remains the standard of care for patients with small renal lesions but in patients with significant comorbidities ablative therapies such as cryoablation and radiofrequency ablation may lead to local cancer control and avoid surgical complications and morbidity. In the setting of metastatic RCC, radical nephrectomy, or cytoreductive nephrectomy, is considered a palliative surgery, usually part of a multimodality treatment approach that requires systemic treatments.

    Glycogen-rich clear cell (GRCC) is a rare subtype of breast carcinoma characterized by carcinoma cells containing an optically clear cytoplasm and intracytoplasmic glycogen. We present the case of a 55-year-old woman with a palpable mass in the right breast and clinical signs of locally advanced breast cancer (LABC). The diagnosis of GRCC carcinoma was based on certain histopathological characteristics of the tumor and immunohistochemical analysis. To our knowledge, this is the first case of GRCC LABC with intratumoral calcifications. There is no evidence of recurrence or metastatic disease after 14 months’ follow-up. PMID:22087097

    Clinical imaging techniques for diagnosing breast cancer mainly include X-ray mammography, ultrasound, and magnetic resonance imaging (MRI), which have respective drawbacks. Multiphoton microscopy (MPM) has become a potentially attractive optical technique to bridge the current gap in clinical utility. In this paper, MPM was used to image normal and ductal cancerous breast tissues, based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). Our results showed that MPM has the ability to exhibit the microstructure of normal breast tissue, ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) lesions at the molecular level comparable to histopathology. These findings indicate that, with integration of MPM into currently accepted clinical imaging system, it has the potential to make a real-time histological diagnosis of mammary ductal carcinoma in vivo.

    Purpose: To investigate the role of galectin-1 in patients with cervical cancer after definitive radiation therapy. Methods and Materials: We reviewed 154 patients with International Federation of Gynecology and Obstetrics stage I-II squamous cell carcinoma. Patients underwent curative-intent radiation therapy. Paraffin-embedded tissues were analyzed using immunohistochemistry staining for galectin-1. The rates of cancer-specific survival (CSS), local recurrence (LR), and distant metastasis were compared among patient tissue samples with no, weak, and strong galectin-1 expression. The Kaplan-Meier method and the Cox proportional hazard model with hazard ratios and 95% confidence intervals (CIs) were used for univariate and multivariate analyses, respectively. Results: The areas under the curve for the intracellular expression scores of galectin-1 for both LR and CSS were significantly higher than those for stromal expression. There were no significant differences in the demographic data, such as stage and serum tumor markers, between patients with and without intracellular expression of galectin-1 in cancer tissue samples. Using multivariate analyses, the hazard ratios of LR and CSS were 2.60 (95% CI 1.50-4.52) (P=.001) and 1.94 (95% CI 1.18-3.19) (P=.010), respectively. Conclusion: Galectin-1 is an independent prognostic factor associated with LR and CSS in stage I-II cervical cancer patients undergoing definitive radiation therapy. Further studies targeting galectin-1 may improve the local control of cervical cancer.

    Methylation of p16 is an important mechanism in cervical carcinogenesis. However, the relationship between cervical squamous cell carcinoma (SCC) and Epstein-Barr virus (EBV) remains controversial. Here, we explored whether EBV infection and/or p16 gene inactivation would play any role in cervical carcinogenesis. Eighty-two specimens included 41 invasive SCCs, 30 cervical intraepithelial neoplasm (CIN; CIN 1, 11 cases, CIN II, 3 cases, CIN III 16 cases) and 11 nonneoplastic cervices. EBV was detected by polymerase chain reaction (PCR) for EBNA-1 and in situ hybridization for EBER-1. The p16 methylation-status and the expression of p16 protein were studied by methylation-specific PCR and immunohistochemistry, respectively. The materials were divided into four groups: 1) nonneoplastic cervices, 2) CIN I, 3) CIN II-III and 4) invasive SCCs. p16 methylation and p16 immunoexpressions increased in CIN and invasive SCCs than nonneoplastic tissue. p16-methylation and p16-immunoreactivities were higher in the EBV-positive group (p=0.009, p<0.001) than in the EBV-negative group. EBV was detected more frequently in CIN and SCCs than nonneoplastic cervices. In conclusion, a correlation between p16 methylation, p16 immunoreactivity and the detection of EBV strongly suggested that the cooperation of EBV and p16 gene may play a synergic effect on cell cycle deregulation.

    Treatment of locally advanced basal cell carcinomas (laBCCs) with large, aggressive, destructive, and disfiguring tumors, or metastatic disease is challenging. Dysregulation of the Hedgehog (Hh) signaling pathway has been identified in the vast majority of basal cell carcinomas (BCCs). There are two United States Food and Drug Administration (US FDA)-approved Hh pathway inhibitors (HPIs) that exhibit antitumor activity in advanced BCC with an acceptable safety profile. Common adverse effects include muscle spasms, dysgeusia, alopecia, fatigue, nausea and weight loss. PMID:27583029

    The adult uterine cervix may exhibit a wide variety of pathologic conditions that include benign entities (eg, cervicitis, hyperplasia, nabothian cysts, cervical polyps, leiomyomas, endometriosis, and congenital abnormalities) as well as malignant lesions, particularly cervical carcinoma. In addition, lesions that arise in the uterine body may secondarily involve the cervix, such as endometrial carcinoma and prolapsed intracavitary masses. Many of these conditions can be identified and characterized at ultrasonography (US), which is considered the first-line imaging examination for the female pelvis. However, examination of the cervix is often cursory during pelvic US, such that cervical disease may be overlooked or misdiagnosed. Transabdominal US of the cervix may not afford sufficient spatial resolution to depict cervical disease in many patients; therefore, endovaginal US is considered the optimal technique. Use of supplemental imaging techniques, particularly the application of transducer pressure on the cervix, may be helpful. This review describes the normal appearance of the cervix at US, the appearance of cervical lesions and conditions that mimic abnormalities at US, and optimal US techniques for evaluation of the cervix. This information will help radiologists detect and diagnose cervical abnormalities more confidently at pelvic US. Online supplemental material is available for this article.

    To compare the efficacy and toxicity of pelvic radiotherapy with concomitant cisplatin plus fluorouracil versus cisplatin alone in patients with locally advanced squamous cell cervical cancer. Twenty women with squamous cell cervical cancer were randomly assigned to receive ether standard whole pelvic radiotherapy with concurrent cisplatin and fluorouracil infusion every 4 weeks or the same radiotherapy with concurrent cisplatin every 1 week. The primary endpoint was the response rate. All patients in cisplatin plus fluorouracil regimen and in cisplatin regimen had complete response. In cisplatin group there was higher frequencies of adverse hematologic effects. Grade 3 or 4 neutropenia occurred in 10% of the cisplatin plus fluorouracil group and in 40% of the cisplatin group (p = 0.049). No difference was found in the response rate, but higher frequencies of hemotological adverse effects in the cisplatin group.

    Purpose: To evaluate the toxicity and effectiveness of celecoxib in combination with definitive chemoradiotherapy (CRT) in women with locally advanced cervical cancer. Methods and Materials: Thirty-one patients were accrued to a phase I-II trial of celecoxib 400 mg by mouth twice per day for 2 weeks before and during CRT. Tumor oxygenation (HP{sub 5}) and interstitial fluid pressure (IFP) were measured before and 2 weeks after celecoxib administration alone. The median follow-up time was 2.7 years (range, 1.1-4.4 years). Results: The most common acute G3/4 toxicities were hematologic (4/31, 12.9%) and gastrointestinal (5/31, 16.1%) largely attributed to chemotherapy. Late G3/4 toxicity was seen in 4 of 31 patients (13.7% actuarial risk at 2 yr), including fistulas in 3 patients (9.7%). Within the first year of follow-up, 25 of 31 patients (81%) achieved complete response (CR), of whom 20 remained in CR at last follow-up. After 2 weeks of celecoxib administration before CRT, the median IFP decreased slightly (median absolute, -4.6 mm Hg; p = 0.09; relative, -21%; p = 0.07), whereas HP{sub 5} did not change significantly (absolute increase, 3.6%; p = 0.51; median relative increase, 11%; p = 0.27). No significant associations were seen between changes in HP{sub 5} or IFP and response to treatment (p = 0.2, relative HP{sub 5} change and p = 0.14, relative IFP change). Conclusions: Celecoxib in combination with definitive CRT is associated with acceptable acute toxicity, but higher than expected late complications. Celecoxib is associated with a modest reduction in the angiogenic biomarker IFP, but this does not correspond with tumor response.

    Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach. In this paper, we report a patient presented with left-sided facial swelling, and the histopathologic examination confirmed primary SNEC of left sinonasal tract. The tumor involved multiple paranasal sinuses with invasion into the left orbit and left infratemporal fossa and metastasized to cervical lymph nodes and bone. The patient encountered devastating outcome in spite of optimal medical management and treatment with palliative chemotherapy highlighting the necessity for further research of primary SNEC of head and neck.

    Since it has been clearly established that multiple drug chemotherapy is more effective than the use of a single drug for advanced carcinoma of the breast, the latter is not commonly used today. However, upon failure of one of two combinations of drugs, if any of these drugs are then tried singly they are rarely useful, and valuable time is lost. It is at this point that megestrol acetate, a potent progestin, was found to be effective in 30 per cent of a series of 161 patients with advanced carcinoma of the breast. This drug was given orally, 40 milligrams, after each meal and at bedtime, without any toxicity or any undesirable reactions, except a weight gain--not fluid retention--in patients less than 55 years of age. The average duration of response was 8.1 months from onset of megestrol acetate therapy and for the group classified as unchanged, 5.2 months. This drug is at least as effective as any steroid or cytotoxic compound but has the advantage of not producing toxicity and, with the exception of weight gain in patients less than 55 years, no undesirable reactions of any kind, such as bone marrow depression, alopecia, nausea, vomiting or diarrhea. Hence, it can be properly administered by the patient's physician or surgeon. Since oncologists known that medroxyprogesterone therapy had not shown promising use for advanced carcinoma of the breast, it was assumed that megestrol acetate also had little activity, and hence, it was not used. However, those who did give it a trial found it a valuable compound in the management of advanced carcinoma of the breast, even after failure of all hormonal or cytotoxic combination trials. It proved to serve as an important addition to our armamentarium in the management of advanced carcinoma of the breast.

    Poorly Differentiated Thyroid Carcinoma (PDTC), especially advanced PDTC, is an aggressive disease and displays a much poorer prognosis compared with well differentiated thyroid carcinoma. Surgery is the recommended treatment in the early stage of PDTC, however, no effective treatment modalities are currently available for advanced PDTCMethods: Two advanced PDTC patients with no radioiodine uptake adopted a cytotoxic chemotherapy with liposomal doxorubicin (35 mg/m(2), day 1) plus cisplatin (75 mg/m(2), day1-3) every 3 weeks. Computer tomography (CT) was performed after 6 cycles (case 1) or 5 cycles (case 2) of chemotherapy Our patients achieved remarkable response with one a Complete Remission (CR) and the other a very good Partial Remission (PR)Conclusion: Our findings indicate that liposomal doxorubicin-based chemotherapy regimens might produce response in PDTC patients, and improve their overall survival and quality of life. Hence we believe this result is very important for oncologists in treating PDTC.

    Despite improvements in cytotoxic chemotherapy agents over the last 50 years, the outlook for patients with many of the most common solid tumours has remained poor. However, in recent years a number of targeted therapies have been licensed in the European Union for use in these cancer types. One such therapy, a tyrosine kinase inhibitor (sorafenib) is now used to treat patients with advanced hepatocellular carcinoma (HCC) and metastatic renal cell carcinoma. This article will explore the role of the oncology nurse in managing patients receiving sorafenib for advanced HCC. A brief overview of sorafenib as a current treatment approved for advanced HCC in the palliative setting is presented. This is followed by a case study-based discussion with particular reference to some of the key care coordination challenges facing the oncology nurse. The management of treatment-related adverse events and the importance of using a multidisciplinary team approach is also reviewed.

    Remodeling of the cervix occurs in advance of labor both at term and at preterm birth. Morphological characteristics associated with remodeling in rodents were assessed in cervix biopsies from women at term (39 weeks' gestation) and preterm (<33 weeks' gestation). Collagen I and III messenger RNA and hydroxyproline concentrations declined in cervix biopsies from women in labor at term and preterm compared to that in the cervix from nonlaboring women. Extracellular collagen was more degraded in sections of cervix from women at term, based on optical density of picrosirius red stain, versus that in biopsies from nonpregnant women. However, collagen structure was unchanged in the cervix from women at preterm labor versus the nonpregnant group. As an indication of inflammation, cell nuclei density was decreased in cervix biopsies from pregnant women irrespective of labor compared to the nonpregnant group. Moreover, CD68-stained macrophages increased to an equivalent extent in cervix subepithelium and stroma from groups in labor, both at term and preterm, as well as in women not in labor at term. Evidence for a similar inflammatory process in the remodeled cervix of women at term and preterm birth parallels results in rodent models. Thus, a conserved final common mechanism involving macrophages and inflammation may characterize the transition to a ripe cervix before birth at term and in advance of premature birth. © The Author(s) 2015.

    Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

    Background Advanced cholangiocellular carcinoma has a poor prognosis with limited therapeutic options. Nab-paclitaxel has recently been described to be beneficial in metastatic pancreatic cancer improving overall and progression free survival (PFS). The potential antitumor activity of nab-paclitaxel in cholangiocellular carcinoma is hitherto unknown. Methods We retrospectively analyzed an institutional cholangiocellular carcinoma registry to determine the potential biological activity of nab-paclitaxel in advanced intrahepatic cholangiocellular carcinoma. Disease control rate (DCR), PFS and overall survival (OS) upon nab-paclitaxel based treatment, after failure of platinum-containing first-line combination chemotherapy, was assessed. Results Twelve patients were identified. Five of 12 patients (42%) received nab-paclitaxel as second line, and 7 patients (56%) as third-line treatment. The objective DCR with nab-paclitaxel was 83% (10/12 patients). One patient had a complete remission (CR), two patients had a partial remission (PR) and 7 patients had stable disease (SD). Disease was rated progressive in two patients. In all 12 patients receiving nab-paclitaxel the median time to progression was 6 months (range, 2.1–19.5 months). Median OS after initiation of nab-paclitaxel treatment was 9 months (2.1–28.4 months). The median time of survival after diagnosis of advanced disease was 21.5 months, whereby 3 patients were alive at the date of censoring (04/01/2015). Conclusions This is the first report suggesting substantial antitumor activity of nab-paclitaxel in advanced cholangiocellular carcinoma. In this small series, nab-paclitaxel based salvage chemotherapy appears to have a biological activity by controlling the disease and positively affecting survival. Randomized trials in this disease entity and subgroup of patients are urged. PMID:27563449

    Introduction: Women presenting with unhealthy cervix needs to be evaluated with Papanicolaou (Pap) smear for epithelial abnormalities. Aim: To detect epithelial cell abnormalities in unhealthy cervix using the 2001Bethesda system of reporting for cervical cytology and to confirm histopathologicaly the findings of Pap smear. Materials and Methods: In this study, 125 women with clinical diagnosis of unhealthy cervix underwent conventional cytology. Cervical biopsies were taken from abnormal areas seen on colposcopy and sent for histopathology. Results: Out of 125 Pap smears, 122 were satisfactory for evaluation (19 normal, 86 negative for intraepithelial lesion or malignancy and 17 with epithelial cell abnormality) and 3 were unsatisfactory (one hemorrhagic and two severe inflammation). Out of 17 (13.60%) cases with epithelial cell abnormality, ASC-US was seen in 6 (4.80%), LSIL in 7 (5.60%), HSIL in 1 (0.80%), squamous cell carcinoma in 1 (0.80%), AGC endocervical in 1 (0.80%) and adenocarcinoma in 1 (0.80%) patients. Cervical biopsy was taken in 67 women. Diagnostic accuracy of Pap smear for preinvasive and invasive disease was 81.15% with overall sensitivity and specificity 78.57% and 88.67% respectively and predictive value of 64.71%. Conclusion: Women with clinical diagnosis of unhealthy cervix should be evaluated by cytology to detect any premalignant or malignant lesions. The Bethesda system for cervical cytology reporting should be used universally as it will give a standardized interpretation. PMID:25386491

    Orthotopic liver transplantation is currently the best treatment option for selected patients with hepatocellular carcinoma (HCC). From 1980 to 2011, 8874 patients with HCC in China underwent liver transplantation. The organ donation classification criteria of China (China criteria), which are established by the Government of China, are divided into three parts: China criteria I, donation after brain death; China criteria II, donation after cardiac death and China criteria III, donation after dual brain-cardiac death. Data from the China Liver Transplant Registry(CLTR) System shows that patients within the Milan criteria have higher survival rates than those who are beyond these criteria. Based on CLTR data, altogether 416 patients received living-donor liver transplantation(LDLT) in China. Their 1-year and 3-year survival rates were significantly higher than those of the non-LDLT recipients. The most common early stage(<30 days after liver transplantation) complications include pleural effusion, diabetes, peritoneal effusion or abscess, postoperative infection, hypertension and intraperitoneal hemorrhage; while the most common late stage (≥ 30 days after liver transplantation) complications were diabetes, hypertension, biliary complications,postoperative infection, tacrolimus toxicity and chronic graft rejection. The incidence of vascular complication, which is the main reason for acute graft failure and re-transplantation, was 2.4%. Liver transplantation is an effective treatment for patients with HCC in China.

    A multimodality treatment program has been applied to ovarian carcinoma at the Johns Hopkins Hospital since August 1975. Forty-nine patients were subdivided into 23 patients with maximally resected Stage III micrometastatic, and 26 patients with significant retained disease, 20 with Stage III macrometastatic and 6 with Stage IV. After initial pilot studies, those patients with minimally retained disease entered a randomized prospective study. Antiovarian antiserum was used in one arm of the study; in both study arms colloidal P-32, delayed split whole abdominal irradiation, and maintenance melphalan were used. For the 23 patients with micrometastatic disease the cumulative survival and survival without evidence of disease at four years is 78 and 34% respectively. Twenty-six patients with macrometastatic disease were treated with or without intraperitoneal antiserum and multiagent chemotherapy; their cumulative one year survival is 50%. The lack of significant toxicity of intraperitoneal antiovarian antiserum and the results of multimodality therapy indicate the feasibility of this therapeutic approach to further improve ovarian cancer therapy.

    The present study was designed to assess the levels of advanced oxidation protein products (AOPP) and percent hemolysis (that indirectly indicates the degree of membrane damage secondary to lipid peroxidation) in colorectal carcinoma. Glutathione (GSH), total thiols and albumin were measured to determine the antioxidant status. Considering the dynamic interaction between various antioxidants in the body, we measured the total antioxidant activity (AOA). Globulin was measured to assess the inflammatory response secondary to oxidative stress. Investigations were conducted in 45 cases of recently diagnosed primary colorectal adenocarcinoma. As control, 45 age and sex matched healthy persons were chosen. GSH was estimated in whole blood, percent hemolysis in RBC suspension and other parameters in plasma. We observed a very high significant increase (P<0.001) in AOPP, percent hemolysis and a highly significant increase (P<0.01) in globulin in colorectal carcinoma. We observed a very high significant decrease (P<0.001) in whole blood GSH, total thiols, albumin, AOA and a significant decrease (P<0.05) in plasma GSH in colorectal carcinoma. A very high significant negative correlation between percent hemolysis and AOA and an apparent negative correlation between total thiols and AOPP was seen in colorectal carcinoma. This demonstrated oxidative stress, decreased antioxidant status and secondary inflammatory response in colorectal carcinoma.

    Background Ovarian carcinoma is the most important cause of gynecological cancer-related mortality in Western societies. Despite the improved median overall survival in patients receiving chemotherapy regimens such as paclitaxel and carboplatin combination, relapse still occurs in most advanced diseased patients. Increased angiogenesis is associated with rapid recurrence and decreased survival in ovarian cancer. This study was planned to identify an angiogenesis-related gene expression profile with prognostic value in advanced ovarian carcinoma patients. Methodology/Principal Findings RNAs were collected from formalin-fixed paraffin-embedded samples of 61 patients with III/IV FIGO stage ovarian cancer who underwent surgical cytoreduction and received a carboplatin plus paclitaxel regimen. Expression levels of 82 angiogenesis related genes were measured by quantitative real-time polymerase chain reaction using TaqMan low-density arrays. A 34-gene-profile which was able to predict the overall survival of ovarian carcinoma patients was identified. After a leave-one-out cross validation, the profile distinguished two groups of patients with different outcomes. Median overall survival and progression-free survival for the high risk group was 28.3 and 15.0 months, respectively, and was not reached by patients in the low risk group at the end of follow-up. Moreover, the profile maintained an independent prognostic value in the multivariate analysis. The hazard ratio for death was 2.3 (95% CI, 1.5 to 3.2; p<0.001). Conclusions/Significance It is possible to generate a prognostic model for advanced ovarian carcinoma based on angiogenesis-related genes using formalin-fixed paraffin-embedded samples. The present results are consistent with the increasing weight of angiogenesis genes in the prognosis of ovarian carcinoma. PMID:19112514

    We report a case of recurrent major hemorrhage in a patient with advanced head and neck squamous cell carcinoma. Before and between the bleeding episodes, the functional level of the patient was remarkably high. Therefore, an attempt at bleeding control with superselective embolization with Ethibloc was made. Because of its specific characteristics, this substance is almost ideal for the purpose of palliative embolization. The material used and the technique of application are described in detail. After the procedure, no hemorrhage occurred for more than 4 months. We recommend superselective embolization, preferably with Ethibloc, for minimally invasive control of recurrent bleeding as palliative treatment in selected patients with advanced head and neck carcinoma, since significant benefit in terms of the quality of life may result.

    The patient was a 71-year-old man who was diagnosed with anal fistula 50 years previously. He complained of mucous and bloody stools. He was diagnosed with a carcinoma associated with anal fistula after biopsy. Image examination showed that the tumor was filled with mucinous substances and that it had invaded the levator ani muscle, with left external iliac and left inguinal lymph node metastases. Therefore, preoperative chemoradiotherapy for locally advanced cancer was administered. After chemoradiotherapy, the tumor and metastatic lymph nodes reduced in size. We performed laparoscopic abdominoperineal resection. Histopathologically, the tumor was revealed as a mucinous adenocarcinoma, but no cancer cells were present on the surgical margin. This case suggested that preoperative chemoradiotherapy could be effective for locally advanced carcinoma associated with anal fistula.

    There is relatively little literature on adjuvant radiotherapy after radical nephroureterectomy with bladder cuff excision (RNU) for patients with upper tract urothelial carcinoma (UTUC). This study was designed to determine the efficacy of adjuvant radiotherapy for patients with pT3N0M0 UTUC. We retrospectively reviewed 198 patients treated with RNU between December 2001 and January 2015. Postoperative radiotherapy was administered in 40 (20.2%) of patients. Patients who received radiotherapy were younger than those that did not (65.2 vs. 70.5 years, p = 0.023). With median follow up of 29.1 months, Kaplan-Meier analysis with the log-rank test demonstrated no significant differences between those omitting vs receiving adjuvant radiotherapy in regards to 2-year rates of overall survival (72.0% vs. 73.4%, p = 0.979), cancer-specific survival (73.2% vs. 75.3%, p = 0.844), and recurrence-free survival (61.2% vs. 66.3%, p = 0.742). However, in multivariable analysis with Cox regression, young age, absence of chronic kidney disease, negative lymphovascular invasion, negative surgical margin, and adjuvant chemotherapy were also associated with better cancer-specific survival. In conclusion, adjuvant radiotherapy did not offer any significant benefit in terms of overall, cancer-specific, and recurrence-free survivals in patients with pT3N0M0 UTUC after RNU. More effective systemic adjuvant chemotherapy is necessary to improve the outcome of these patients. PMID:27910890

    Hepatocellular carcinoma (HCC) is a lethal tumor, claiming over half a million lives per year. Treatment of HCC is commonly performed without curative intent, and palliative options dominate, including catheter-based therapies, namely, transarterial chemoembolization and yttrium-90 ((90)Y) radioembolization. This review will showcase the performance of (90)Y radioembolization for the treatment of HCC, focusing on recent seminal data and technical advances. In particular, novel radioembolization treatment concepts are discussed and compared with conventional HCC therapy.

    Stereotactic body radiotherapy (SBRT) has been shown to improve overall survival in patients with advanced hepatocellular carcinoma. This study aimed to assess the cost-effectiveness of SBRT compared to sorafenib which is the only drug for advanced hepatocellular carcinoma. A Markov decision-analytic model was performed to compare the cost-effectiveness of SBRT and sorafenib for unresectable advanced hepatocellular carcinoma. Patients transitioned between three health states: stable disease, progression disease and death. We calculated the data on cost from the perspective of our National Health Insurance Bureau. Sensitivity analyses were conducted to determine the impact of several variables. The incremental cost effectiveness ratio (ICER) for sorafenib compared to SBRT was NT$3,788,238 per quality-adjusted life year gained (cost/QALY), which was higher than the willingness to pay threshold of Taiwan according to WHO's guideline. One-way sensitivity analysis revealed that the utility of progression disease for the sorafenib treatment, utility of progression free survival for SBRT, utility of progression free survival for sorafenib, utility of PFS to progression disease for SBRT and transition probability of progression disease to dead for SBRT were the most sensitive parameters in all cost scenarios. The Monte-Carlo simulation demonstrated that the probability of cost-effectiveness at a willingness to pay threshold of NT$ 2,213,145 per QALY was 100 % and 0 % chance for SBRT and sorafenib. This study indicated that SBRT for advanced hepatocellular carcinoma is cost-effective at a willingness to pay threshold as defined by WHO guideline in Taiwan.

    Gastric cancer represents one of the most common cancer worldwide. Unfortunately, the majority of patients present in advanced stage and outcome still remains poor with high mortality rate despite decreasing incidence and new diagnostic and therapeutic strategies. Although utility of classical chemotherapy agents has been widely explored, advances have been slow and the efficacy of these agents has reached a plateau of median overall survival not higher than 12 months. Therefore, researchers focused their attention on better understanding molecular biology of carcinogenesis and deeper knowledge of the cancer cell phenotype, as well on development of rationally designed drugs that would target specific molecular aberrancies in signal transduction pathways. These targets include cell surface receptors, circulating growth and angiogenic factors and other molecules involved in downstream intracellular signaling pathways, including receptor tyrosine kinases. However, therapeutic advances in gastric cancer are not so encouraging when compared to other solid organ malignancies such as breast and colorectal cancer. This article reviews the role of targeted agents in gastric cancer as single-agent therapy or in combination regimens, including their rational and emerging mechanism of action, current and emerging data. We focused our attention mainly on published phase III studies, therefore cornerstone clinical trials with trastuzumab and bevacizumab have been largely discussed. Phase III studies presented in important international meetings are also reviewed as well phase II published studies and promising new therapies investigated in preclinical or phase I studies. Today, in first-line treatment only trastuzumab has shown significantly increased survival in combination with chemotherapy, whereas ramucirumab as single agent resulted effective in progressing patients, but - despite several disappointing results - these are the proof of principle that targeting the proper

    Objective: To assess the efficacy of PDT to: Palliate symptoms, control disease and extend survival in patients with advanced inoperable cancer. Subject and Method: 55 Males and 23 females aged between 45-81 years (mean 66 years) with inoperable and advanced lung cancer with > 5O. obstructive lesions of the main, lobar or segmental bronchi. Patients had pre-treatment routine clinical radiological, functional and endoscopic assessment with proven histological diagnosis. Protocol of PDT was; Intravenous injection of 2 mg/Kg bodyweight Polyhaematoporphyrin (equivalent to Photofrin) or Photofrin followed 24-72 hours later by illumination of tumour using 630 nm light (Oxford Laser) delivered via an optical fibre with end diffuser. Treatments were carried out under general anaesthesia as a day case procedure. Patients were rebronchoscoped for debridement/retreatment 4-7 days later. Results: There was no treatment related mortality. Two patients developed mild photosensitivity reaction. All patients showed symptomatic improvement with good initial functional and radiological amelioration. Every patient responded to treatment. Seven patients had complete response and negative histology for 3-12 months. After the first treatment average Forced Vital Capacity (FVC) and Forced Expiratory Volume in one second (FEV1) improvement was 0.5 litres and 0.4 litres respectively. Twenty five percent of patients (nr 19) survived more than 2 years, 10'. (nr=8) between 1-2 years and the remaining 51 patients less than a year. Conclusion: PDT should be considered as a therapeutic modality for all stages of lung cancer and is an excellent treatment modality for palliation in advanced bronchial malignancies.

    Wernicke's encephalopathy is a life-threatening neurologic complication of thiamine deficiency. Though the presentation of symptoms can vary widely, the classical triad is founded on ophthalmoplegia, alteration of mental status, and gait disturbance. We describe a case of Wernicke's encephalopathy in an oncology patient shortly after concurrent 5-fluorouracil, carboplatin, and radiotherapy for locally advanced oropharyngeal cancer, presenting as complete bilateral blindness, ataxia, nystagmus, and confusion. Thiamine was given based on clinical suspicion and rapid improvement of clinical findings occurred. An MRI performed later supported the diagnosis of Wernicke's encephalopathy. A multifactorial etiology of thiamine deficiency from nutritional deficits and neurotoxic effects of chemotherapy are hypothesized. PMID:26623207

    To assess the toxicity profile of erlotinib therapy combined with postoperative adjuvant radiation therapy in patients with advanced cutaneous squamous cell carcinoma. This was a single-arm, prospective, phase 1 open-label study of erlotinib with radiation therapy to treat 15 patients with advanced cutaneous head-and-neck squamous cell carcinoma. Toxicity data were summarized, and survival was analyzed with the Kaplan-Meier method. The majority of patients were male (87%) and presented with T4 disease (93%). The most common toxicity attributed to erlotinib was a grade 2-3 dermatologic reaction occurring in 100% of the patients, followed by mucositis (87%). Diarrhea occurred in 20% of the patients. The 2-year recurrence rate was 26.7%, and mean time to cancer recurrence was 10.5 months. Two-year overall survival was 65%, and disease-free survival was 60%. Erlotinib and radiation therapy had an acceptable toxicity profile in patients with advanced cutaneous squamous cell carcinoma. The disease-free survival in this cohort was comparable to that in historical controls. Copyright © 2013 Elsevier Inc. All rights reserved.

    The present study aimed to evaluate efficacy and adverse effects of Nimotuzumab combined with docetaxel-cisplatin-fluorouracil regimen in the treatment of advanced oral carcinoma. Nine patients with advanced oral carcinoma were treated with Nimotuzumab combined with docetaxel-cisplatin-fluorouracil regimen (test group). The treatment was given as follows: Nimotuzumab 200 mg, given as intravenous infusion once a week for 6 weeks; docetaxel and cisplatin, 75 mg/m(2) each, on day 1 only; 5-fluorouracil, 750 mg/m(2) infused continually for 8 h, used from day 1 to 5; the total cycle was for 21 days. Another eight patients comprised control group (docetaxel-cisplatin-fluorouracil regimen alone). Study patients from both groups were evaluated for objective response. The response rate was significantly (p = 0.044) higher in test group (88.9 vs. 37.5 % in control group). The disease control rate also tended to be higher in test group (100 vs. 62.5 % in control group; p = 0.083). The major adverse effects were bone marrow suppression, nausea, vomiting, and alopecia. The incidence of adverse effects was similar between both study groups. In conclusion, Nimotuzumab combined with docetaxel-cisplatin-fluorouracil regimen is effective and safe in the treatment of advanced oral carcinoma.

    Purpose: To investigate the feasibility and efficacy of concurrent chemoradiation in combination with erlotinib for locally advanced esophageal carcinoma. Methods and Materials: Twenty-four patients with locally advanced esophageal carcinoma were treated with concurrent chemoradiotherapy. A daily fraction of 2.0 Gy was prescribed to a total dose of 60 Gy over 6 weeks. Concurrent paclitaxel (135 mg/m{sup 2}, d{sub 1}) and cisplatin (20 mg/m{sup 2}, d{sub 1-3}) were administered on Day 1 and Day 29 of the radiotherapy. Erlotinib, an oral epidermal growth factor receptor-tyrosine kinase inhibitor, was taken by every patient at the dose of 150 mg daily during the chemoradiotherapy. Results: The median follow-up of the 24 patients was 18.6 months (range, 7.1-29.6 months). The 2-year overall survival, local-regional control, and relapse-free survival were 70.1% (95% CI, 50.4-90%), 87.5% (95% CI, 73.5-100%), and 57.4% (95% CI, 36.3-78.7%), respectively. During the chemoradiotheapy, the incidences of acute toxicities of Grade 3 or greater, such as leucopenia and thrombocytopenia, were 16.7 % (4/24) and 8.3% (2/24). Conclusions: Application of concurrent chemoradiotherapy in combination with erlotinib for locally advanced esophageal carcinoma yielded satisfactory 2-year overall survival and local-regional control. The toxicities were well tolerated.

  10. Advanced gastroesophageal carcinoma: an update on the current therapeutic landscape.

    2012-01-01

    Gastroesophageal cancers are usually diagnosed in an advanced stage, and effective treatment options remain limited. The discovery of new drugs to treat these diseases has been slow for decades. An occasional favorable outcome, trastuzumab, in patients with HER2 protein-overexpressing tumors, is welcome but not sufficient. For advanced gastroesophageal adenocarcinoma (AGC), fluoropyrimidines (given orally or intravenously) plus a platinum compound (usually cisplatin) have been accepted as a global reference to streamline new drug development. The addition of a third cytotoxic (docetaxel or epirubicin) can produce modest prolongation of overall survival. In some European countries, the irinotecanbased regimen is considered as an alternative to platinum-based first-line therapy. Selecting a safe, effective, and convenient regimen is desirable and is the focus of current research. Additionally, it appears that survival differences by regions (e.g., Asians survive longer compared to Western and South American patients) are likely due to second- and third-line therapies, differences in tumor biology, or unknown reasons. Future progress could come from 1 of 2 approaches: (1) conducting many empiric phase III trials in unselected patients or (2) through detailed studies of molecular biology to develop rational therapies. We provide a brief update on the treatment of AGC. Copyright © 2012 S. Karger AG, Basel.

    Purpose To evaluate the tolerability and efficacy of poly(ADP-ribose) polymerase (PARP) inhibition by veliparib during cytotoxic topotecan administration with filgrastim or pegfilgrastim neutrophil support in women with persistent or recurrent uterine cervix cancer. Experimental Design This phase I–II trial examined twice-daily oral veliparib (10 mg) given during once-daily intravenous topotecan (0.6 mg/m2) on days 1–5 of each treatment cycle. Cycles were repeated every 21 days until disease progression or until toxicity prohibited further therapy. Toxicity and objective response rate were primary endpoints. Results Twenty-seven women were enrolled. Frequently reported grade 3 or higher treatment-related toxicities were anemia (59%), thrombocytopenia (44%), leukopenia (22%), and neutropenia (19%). There were 2 partial responses (7% [90% confidence interval: 1–22%]). Four patients had a disease progression date more than 6 months after the start of veliparib-topotecan therapy. Patients with low immunohistochemical expression (0–1+) of PARP-1 in their primary uterine cervix cancer were more likely to have a longer progression-free interval (hazard ratio: 0.25, P = 0.02) and survival (hazard ratio: 0.12, P = 0.005) after veliparib-topotecan therapy. Conclusions Clinical activity of a veliparib-topotecan combination was minimal in women with persistent or recurrent uterine cervix cancer. Women whose uterine cervix cancers express PARP-1 at low levels may benefit preferentially from PARP inhibitors combined with cytotoxic therapies, suggesting further study of PARP expression as an integral triage biomarker.

    To establish the cytological criteria to identify the urothelial cells in cervical smears in order to avoid mistakes in the cytological diagnosis. Cervical smears from 34 post menopausal women with vesicovaginal fistulas, advanced bladder prolapse and genital erosive lichen planes (vulvar kraurosis) (Group 1) and transitional cell metaplasia of the cervix (TCM, Group 2) were stained with Papanicolaou technique. The cervical samples were taken during the routine annual examination for prevention of the uterine cancer. The smears of cervix from Group 1 showed urothelial cells from the three layers of the transitional epithelium. The umbrella cells are the bigger ones with relatively large nuclei. Frequently, they are multinucleated with single or multiple nucleoli and a typical "frothy" cytoplasm (cytoplasmic vacuoles). The cells of the Group 2 showed nuclei with oval to spindled shapes, some tapered ends, less cytoplasm than squamous metaplastic cells, powdery chromatin, small nucleoli and nuclear grooves. The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs) due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL) cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper.

    Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. If left untreated, BCCs can become locally aggressive or even metastasize. Currently available treatments include local destruction, surgery, and radiation. Systemic options for advanced disease are limited. The Hedgehog (Hh) pathway is aberrantly activated in a majority of BCCs and in other cancers. Hh pathway inhibitors are targeted agents that inhibit the aberrant activation of the Hh pathway, with smoothened being a targeted component. Sonidegib is a novel smoothened inhibitor that was recently approved by the US Food and Drug Administration. This review focuses on BCC pathogenesis and the clinical efficacy of sonidegib for the treatment of advanced BCC. PMID:27695345

    We report the case of a 72-yr-old man who suffered from severe chronic emphysema with poor pulmonary function, and who had advanced cancer of the stomach. Proton beam radiotherapy was applied to the lesion, since surgery was contraindicated. The total dose to the stomach lesion was 61 Gy in 7 wk. The tumor on the stomach regressed, with flattening of the round wall of the lesion. The reactive changes of the proton beam radiotherapy, based on the histopathological examination, revealed extensive tumor necrosis and sparing of vital architecture of normal tissue around the irradiated tumor tissue. Only small clusters of vital or devitalized tumor cells with less than approximately 5% of the whole tumor tissue remained after treatment. We suggest that a high dose of radiation delivered by well-defined proton field could result in an improved therapeutic outcome without undue risk of injury to normal tissue.

    Neoadjuvant chemoradiation is now considered the standard care for locally advanced rectal carcinoma (T3-4 or/and N1-2 lesions), but the accuracy of staging examinations including endorectal ultrasonography (ERUS) and MRI is far from excellent. In addition, the above staging equipment or professionals who perform the examinations may not be available in some hospitals, while preoperative colonoscopy and biopsy are usually obtainable in most hospitals. The objective of the present study was to investigate the clinical and pathological characteristics of locally advanced rectal carcinoma and identify candidates for neoadjuvant chemoradiation. This was a retrospective study. Patients who were treated for rectal cancer at Changhai Hospital from January 1999 to July 2008 were identified from our prospectively collected database. Statistical analysis was performed using SPSS Software System (version 15.0). The Mann-Whitney test, chi-square test and multivariate Logistic regression analysis were performed. A total of 1005 cases were included in this research, of which 761 cases were identified as locally advanced rectal carcinoma depending on postoperative TNM staging. The results of multivariate Logistic regression analysis indicated seven independent risk factors that could be used to predict a locally advanced rectal carcinoma independently: a high grade (including poor differentiation and undifferentiation) (OR: 3.856; 95% CI: 2.064 to 7.204; P = 0.000); large tumor size (OR: 2.455; 95% CI: 1.755 to 3.436; P = 0.000); elevated preoperative serum CEA level (OR: 1.823; 95% CI: 1.309 to 2.537; P = 0.000); non-polypoid tumor type (OR: 1.758; 95% CI: 1.273 to 2.427; P = 0.001); the absence of synchronous polyps (OR: 1.602; 95% CI: 1.103 to 2.327; P = 0.013); the absence of blood in stool (OR: 1.659; 95% CI: 1.049 to 2.624; P = 0.030); and a greater circumferential tumor extent (OR: 1.813; 95% CI: 1.055 to 3.113; P = 0.031).

    Advanced biliary tract carcinomas (BTCs) are often diagnosed at an advanced/metastatic stage and have a poor prognosis. The combination of gemcitabine and oxaliplatin (GEMOX) has shown promising activity in this setting. This international phase II study evaluated the efficacy and safety of GEMOX as first-line therapy in patients with advanced BTCs. Eligible patients with previously untreated locally advanced or metastatic BTC received gemcitabine 1000 mg m−2 (day 1) and oxaliplatin 100 mg m−2 (day 2), every 2 weeks. Seventy patients were enroled; 72.9% had metastatic disease. Sixty-seven patients were treated. There were 10 confirmed partial responses (14.9%; 95% confidence interval (CI), 7.4–25.7%) in the treated population (RECIST). Twenty-four patients (35.8 %) had stable disease. The objective response rate was 20.5% in patients with non-gallbladder cancers (9/44 patients) and 4.3% in patients with gallbladder cancers (1/23). Median overall survival for the intent-to-treat population was 8.8 months (95% CI, 6.9–11.1%) and progression-free survival was 3.4 months (95% CI, 2.5–4.6%). Grade 3/4 toxicities included thrombocytopenia (14.9% of patients), alanine aminotransferase elevation (13.4%), anaemia (10.4%), neutropenia (11.9%) and pain (11.9%). In this study, GEMOX demonstrated activity in non-gallbladder carcinoma, but poor activity in gallbladder carcinoma. GEMOX is well tolerated in advanced BTCs. PMID:19238628

    There are limited data on the safety and efficacy of immunotherapy for patients with advanced pancreatic cancer (APC). A meta-analysis of single-arm trials is proposed to assess the efficacy and safety of immunotherapy for APC. Eighteen relevant studies involving 527 patients were identified. The pooled disease control rate (DCR), overall survival (OS), progression free survival (PFS), and 1-year survival rate were estimated as 59.32%, 7.90 months, 4.25 months, and 30.12%, respectively. Subgroup analysis showed that the pooled OS, PFS, and 1-year survival rate were significantly higher for autologous activated lymphocyte therapy compared with peptide-based vaccine therapy (OS: 8.28 months vs. 7.40 months; PFS: 6.04 months vs. 3.86 months; 1-year survival rate: 37.17% vs. 19.74%). Another subgroup analysis demonstrated that the pooled endpoints were estimated as obviously higher for immunotherapy plus chemotherapy compared with immunotherapy alone (DCR: 62.51% vs. 47.63%; OS: 8.67 months vs. 4.91 months; PFS: 4.91 months vs. 3.34 months; 1-year survival rate: 32.32% vs. 21.43%). Of the included trials, seven trials reported no treatment related adverse events , five trials reported (16.6 3.9) % grade 3 adverse events and no grade 4 adverse events. In conclusion, immunotherapy is safe and effective in the treatment of APC. PMID:27992378

    Retrospective studies have recently demonstrated a significant correlation between dose intensity of chemotherapy and response rates and survival in various diseases including epithelial ovarian carcinoma. As part of a proposed randomised trial to assess the effect of dose intensity on outcome in ovarian carcinoma, a pilot study has been undertaken to determine the toxicity and efficacy of the high intensity therapy. Nineteen patients with advanced ovarian carcinoma received initial treatment with cisplatin 120 mg m-2 i.v. day 1, and cyclophosphamide 1,000 mg-2 i.v. day 1, given at 21-day intervals for six cycles. The average relative dose intensity of this therapy is 1.14 when compared with the CHAP regimen. Severe toxicity was experienced by most patients. The median received average relative dose intensity was 0.90, with only one patient receiving treatment to the proposed intensity. Randomised studies of the effect of dose intensity in ovarian carcinoma are essential, but an initial step must be to assess whether the proposed high dose treatment can be delivered. PMID:2155645

    Thymic carcinoma is a rare but lethal mediastinal cancer. The optimal treatment for advanced thymic carcinoma is not yet established. This report is the first known of stereotactic ablative radiotherapy (sabr) with CyberKnife (Accuray, Sunnyvale, CA, U.S.A.) as definitive therapy for thymic carcinoma. The patient, a 70-year-old woman with thymic carcinoma, invasion into neighboring organs, and pleural metastases-underwent CyberKnife sabr at 40 Gy in 5 fractions for two lesions, one in the thymus and one in the right paraspinal pleura. After 61 months of observation, a partial response was observed in the irradiated fields. However, disease progression in the non-irradiated pleura was noted. The patient underwent salvage CyberKnife sabr for the four initially nonirradiated pleural lesions. Computed tomography images obtained 10 months after the salvage therapy revealed a partial response. The patient is living, with progression-free irradiated lesions and no radiation-related toxicity. CyberKnife sabr is feasible for patients who are unable to undergo either surgery or conventionally fractionated radiation therapy.

    Angiogenesis in general and the vascular endothelial growth factor (VEGF) signaling axis in particular is a validated target in renal cell carcinoma (RCC). Clear-cell carcinoma of the kidney is now recognized as a malignancy that is sensitive to inhibitors of the VEGF pathway. Treatment options for patients with metastatic renal cell carcinoma have evolved in dramatic fashion over the past 6 years, and a new paradigm has developed. The cytokines interferon-α and interleukin-2 were previously utilized for therapy, but since December 2005, six new agents have been approved in the United States for the treatment of advanced RCC. Two are tyrosine kinase inhibitors (TKI's) including sunitinib and recently pazopanib, and the multikinase inhibitor sorafenib. The current review examines the evolving data with the next generation of TKI's, axitinib and tivozanib being developed for the treatment of advanced RCC. These agents were synthesized to provide increased target specificity and enhanced target inhibition. The preclinical and clinical data are examined, an overview of the development of these TKI's is provided, and discussion plus speculation concerning their potential roles as RCC therapy is provided.

    The survival, pattern of failure and complications in 47 patients with Stage III and IV cancers of the glottis, supraglottis and hypopharynx treated with surgery and postoperative radiotherapy using a new treatment technique referred to as mini-mantle were analyzed. The absolute survival probability of the entire group was 53 and 31% at 3 and 5 years. The local control probability at 3 and 5 years was 63 and 58%, and was higher for the supraglottic/hypopharyngeal than for glottic carcinomas. Five patients developed complications requiring surgical correction, but none experienced mortality. Moderate complications were treated conservatively without lasting sequelae. This technique is a reasonable safe and efficient procedure and can be effectively employed for the management of advanced laryngeal and hypopharyngeal carcinomas after definitive surgery.

    Treatment of basal cell carcinoma (BCC) usually involves surgical interventions and laser ablation, but in locally advanced BCC, which arise either from earlier untreated lesions or from recurrence of aggressive BCC, surgery and radiotherapy are not helpful. Vismodegib, the first oral-targeted therapy for locally advanced and metastatic BCC, unsuitable for surgery or radiotherapy, was recently approved by US Food and Drug Administration (FDA). The drug was under the priority review program of FDA and was approved on the basis of promising results of phase II trial. Vismodegib acts by targeting the hedgehog pathway, which is activated abnormally in most BCCs. Approval of vismodegib is a big step ahead in the treatment of advanced BCC, where there was no other effective drug therapy till now.

    Squamous cell carcinoma of the larynx and hypopharynx has the potential to invade the thyroid gland. Despite this risk, the proposition of either partial or total thyroidectomy as part of the surgical treatment of all such cases remains controversial. To evaluate the frequency of invasion of the thyroid gland in patients with advanced laryngeal or hypopharyngeal squamous cell carcinoma submitted to total laryngectomy or pharyngolaryngectomy and thyroidectomy; to determine whether clinic-pathological characteristics can predict glandular involvement. A retrospective case series with chart review, from January 1998 to July 2013, was undertaken in a tertiary care university medical center. An inception cohort of 83 patients with larynx/hypopharynx squamous cell carcinoma was considered. All patients had advanced stage disease (clinically T3-T4) and underwent total laryngectomy or total pharyngolaryngectomy in association with thyroidectomy. Adjuvant therapy was indicated when tumor or neck conditions required. Frequency of thyroid cartilage invasion was calculated; univariate and multivariate analysis of demographic, clinical and pathological characteristics associated with cartilage invasion were performed. The overall frequency of invasion of the thyroid gland was 18.1%. Glandular involvement was associated with invasion of the following structures: anterior commissure (odds ratio=5.13; 95% confidence interval 1.07-24.5), subglottis (odds ratio=12.44; 95% confidence interval 1.55-100.00) and cricoid cartilage (odds ratio=15.95; 95% confidence interval 4.23-60.11). Invasion of the thyroid gland is uncommon in the context of laryngopharyngeal squamous cell carcinoma. Clinical and pathological features such as invasion of the anterior commissure, subglottis and cricoid cartilage are more associated with glandular invasion.

    2011-01-01

    Purpose: The clinical success of hyperthermia adjunct to radiotherapy depends on adequate temperature elevation in the tumor with minimal temperature rise in organs at risk. Existing technologies for thermal treatment of the cervix have limited spatial control or rapid energy falloff. The objective of this work is to develop an endocervical applicator using a linear array of multisectored tubular ultrasound transducers to provide 3-D conformal, locally targeted hyperthermia concomitant to radiotherapy in the uterine cervix. The catheter-based device is integrated within a HDR brachytherapy applicator to facilitate sequential and potentially simultaneous heat and radiation delivery. Methods: Treatment planning images from 35 patients who underwent HDR brachytherapy for locally advanced cervical cancer were inspected to assess the dimensions of radiation clinical target volumes (CTVs) and gross tumor volumes (GTVs) surrounding the cervix and the proximity of organs at risk. Biothermal simulation was used to identify applicator and catheter material parameters to adequately heat the cervix with minimal thermal dose accumulation in nontargeted structures. A family of ultrasound applicators was fabricated with two to three tubular transducers operating at 6.6–7.4 MHz that are unsectored (360°), bisectored (2×180°), or trisectored (3×120°) for control of energy deposition in angle and along the device length in order to satisfy anatomical constraints. The device is housed in a 6 mm diameter PET catheter with cooling water flow for endocervical implantation. Devices were characterized by measuring acoustic efficiencies, rotational acoustic intensity distributions, and rotational temperature distributions in phantom. Results: The CTV in HDR brachytherapy plans extends 20.5±5.0 mm from the endocervical tandem with the rectum and bladder typically <8 mm from the target boundary. The GTV extends 19.4±7.3 mm from the tandem. Simulations indicate that for 60 min

    Background Squamous cell carcinomas of the head and neck (SCCHN) affect approximately 35,000 people in the United States yearly. Although survival has improved with advances in therapy, patients with advanced stages of SCCHN continue to have a poor prognosis. An understanding of rationale for treatment selection, newer developments in therapy, and treatment toxicity is critical. Methods Standard methods of treating locally advanced SCCHN are reviewed. Advances in medical and radiotherapeutic management are discussed and the toxicities of therapy are described. Results Post-operative chemoradiation is used in patients with high risk characteristics. Induction chemotherapy and altered fractionation radiation treatment have been evaluated as alternatives to definitive chemo-radiotherapy. Targeted agents such as cetuximab may prove to increase survival with minimal increase in toxicity profile. Technological improvements such as the use of intensity modulated radiation treatment (IMRT) have proven to decrease some debilitating side effects from radiation treatment. Conclusions Locally advanced SCCHN continues to present a therapeutic challenge. Survival, local control, and quality of life are all goals of treatment. The optimal method of treating locally advanced SCCHN is the subject of ongoing research. Long term side effects can be minimized with the use of newer technologies and with careful treatment planning. PMID:19036056

    From the last few years, hepatitis C virus and the new direct antiviral treatments are being more and more important. In consequence, case studies like the one we present, the appearance of hepatocelullar carcinoma after its eradication with fibrosis grade 2, are getting special interest. In 2007, our patient was treated with pegylated interferon α-2a and ribavirin, having a sustained virological response after it. In this way, liver fibrosis grade 2 was confirmed by a biopsy. Finally, after corroborating a good liver functioning, the patient was discharged (as, according to the guidebooks, an ultrasound scan of screeing every 6 months was not required). In 2014, the patient came to hospital because of a pain at right hypochondrium and he was diagnosed with hepatocelullar carcinoma. A hepatectomy was done objectifying the surgical piece, liver fibrosis grade 2, one more time. Subsequently, a tumour relapse through an abdominal CT scan, a tumour relapse was found and despite the Sorafenib treatment, the patient died on January 2015. This case study provokes curiosity and uncertainty about the attitude which should be taken respect to the monitoring, and hepatocelullar carcinoma screening overall, in patients with a sustained virological response after eradicator treatment and without advanced fibrosis. Nowadays, with the benefits of the new treatments, the amount of patients in this situation is increasing significantly.

    Between December 2005 and October 2009, FDA approved six targeted therapies shown to significantly extend survival for advanced renal cell carcinoma (RCC) patients in clinical trials. This study aimed to examine changes in survival between the pretargeted and targeted therapy periods in advanced RCC patients in a real-world setting. Utilizing the 2000-2010 SEER Research files, a pre-post study design with a contemporaneous comparison group was employed to examine differences in survival outcomes for patients diagnosed with advanced RCC (study group) or advanced prostate cancer (comparison group, for whom no significant treatment innovations happened during this period) across the pretargeted therapy era (2000-2005) and the targeted therapy era (2006-2010). RCC patients diagnosed in the targeted therapy era (N = 6439) showed improved survival compared to those diagnosed in the pretargeted therapy era (N = 7231, hazard ratio (HR) for all-cause death: 0.86, P < 0.01), while the change between the pre-post periods was not significant for advanced prostate cancer patients (HR: 0.97, P = 0.08). Advanced RCC patients had significantly larger improvements in overall survival compared to advanced prostate cancer patients (z = 4.31; P < 0.01). More detailed year-to-year analysis revealed greater survival improvements for RCC in the later years of the posttargeted period. Similar results were seen for cause-specific survival. Subgroup analyses by nephrectomy status, age, and gender showed consistent findings. Patients diagnosed with advanced RCC during the targeted therapy era had better survival outcomes than those diagnosed during the pretargeted therapy era. Future studies should examine the real-world survival improvements directly associated with targeted therapies.

    Background Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is rare, with better clinical outcomes than other lung cancers. However, reports on advanced LELC characteristics and prognosis are lacking. Methods This retrospective study included adults diagnosed with advanced LELC (at least stage IIIA) between January 2003 and December 2015. Clinical characteristics, treatment modalities, and outcomes were recorded. Results Study population comprised 23 patients with a mean age of 63.7±10.6 years. The Eastern Cooperative Oncology Group status on diagnosis was 0 in five patients and 1 in the others. Most patients received multimodality treatment and all received cisplatin-based chemotherapy. Median follow-up duration was 28.8 months. The median progression free survival (PFS) was 14.6 months in patients received palliative chemotherapy. There were nine (39.1%) deaths. The median overall survival (OS) was not achieved. Until July 31, 2016, median OS was 54.1 months for stage IIIB and 27.6 months for stage IV. There was no significant difference in OS among all stages. No prognostic factors were found. Conclusions Advanced LELC responded well to cisplatin-based chemotherapy and/or radiotherapy. Main tumor resection is probably beneficial for advanced LELC. Long-term survival is possible for advanced LELC after multimodality treatment. PMID:28203414

    Background & aims It is unknown whether the addition of locoregional therapies (LRTx) to sorafenib improves prognosis over sorafenib alone in patients with advanced hepatocellular carcinoma (HCC). The aim of this study was to assess the effect of LRTx in this population. Methods A retrospective analysis was performed of patients with advanced HCC as defined by extrahepatic metastasis, lymphadenopathy >2 cm, or gross vascular invasion. Sorafenib therapy was required for inclusion. Survival of patients who received LRTx after progression to advanced stage was compared to those who did not receive LRTx. Results Using an intention to treat analysis of 312 eligible patients, a propensity weighted proportional hazards model demonstrated LRTx as a predictor of survival (HR = 0.505, 95% CI: 0.407–0.628; P < 0.001). The greatest benefit was seen in patients with the largest tumor burden (HR = 0.305, 95% CI: 0.236–0.393; P < 0.01). Median survival in the sorafenib arm was 143 days (95% CI: 118–161) vs. 247 days (95% CI: 220–289) in the sorafenib plus LRTx arm (P < 0.001). Conclusions These results demonstrate a survival benefit with the addition of LRTx to sorafenib for patients with advanced HCC. These findings should prompt a prospective clinical trial to further assess the role of LRTx in patients with advanced HCC. PMID:27154804

    Irreversible electroporation (IRE) is a novel image-guided ablation technique that is increasingly used to treat locally advanced pancreatic carcinoma (LAPC). We describe a 67-year-old male patient with a 5 cm stage III pancreatic tumor who was referred for IRE. Because the ventral approach for electrode placement was considered dangerous due to vicinity of the tumor to collateral vessels and duodenum, the dorsal approach was chosen. Under CT-guidance, six electrodes were advanced in the tumor, approaching paravertebrally alongside the aorta and inferior vena cava. Ablation was performed without complications. This case describes that when ventral electrode placement for pancreatic IRE is impaired, the dorsal approach could be considered alternatively.

    Clinically available targeted agents to treat advanced renal cell carcinoma (RCC) include sunitinib, sorafenib and temsirolimus. Sorafenib and sunitinib have been associated with bleeding in selected trials, but clinical and endoscopic characteristics of gastrointestinal bleeding are not well described. Herein, we report four cases of advanced RCC in which endoscopic hemostasis effectively resolved high-grade, life-threatening gastrointestinal bleeding that occurred during targeted therapy. Although stomatitis and mucositis have occurred during targeted therapies, life-threatening gastrointestinal bleeding is less common. In these four patients, the origins of gastrointestinal bleeding were identified, and complete endoscopic hemostasis was achieved. Endoscopies revealed variable characteristics including angiodysplasia, multiple gastric ulcers and oozing bleeding of the normal mucosa. Although the most effective diagnostic and treatment strategies are disputed, endoscopic examinations are best performed before starting targeted therapies. Additionally, these patients should be monitored even for rare life-threatening events. PMID:26722259

    Treatment of locally advanced penile squamous cell carcinoma (pSCC) remains highly controversial secondary to disease rarity and lack of prospective randomized controlled trials. The current mainstays of care are multi-modality treatment with neoadjuvant chemotherapy and surgery. However, clinicians often have difficulty making recommendations for patients unable to tolerate chemotherapy or surgery due to scarcity of data to guide clinical decision-making. We report two cases of locally advanced pSCC that achieved complete remission after treatment with cisplatin-based neoadjuvant chemotherapy and surgery in one case, and concurrent cisplatin chemoradiation in a second, supporting the use of chemotherapy as part of first-line multimodal therapy. We also discuss additional treatment options for patients unable to tolerate traditional chemotherapy regimens. PMID:28191294

    Basal cell carcinoma (BCC) is the most common skin cancer worldwide. Most occur on the head and neck, where cosmetic and functional outcomes are critical. BCC can be locally destructive if not diagnosed early and treated appropriately. Surgery is the treatment of choice for the majority of high-risk lesions. Aggressive, recurrent or unresectable tumors can be difficult to manage. Until recently, no approved systemic therapy was available for locally advanced or metastatic BCC inappropriate for surgery or radiotherapy. Vismodegib provides a systemic treatment option. However, a consensus definition of advanced BCC is lacking. A multidisciplinary panel with expertise in oncology, dermatology, dermatologic surgery and radiation oncology proposes a consensus definition based on published evidence and clinical experience.

    One hundred ten patients with predominantly advanced laryngeal carcinoma were treated in the period 1969-1978 with planned preoperative radiation therapy followed by surgery. Site distribution was: 63 supraglottic, 26 glottic, 15 transglottic and 6 subglottic. There were 4 Stage II patients, 66 Stage III and 40 Stage IV. Preoperative radiation therapy consisted of Telecobalt irradiation to a total dose of 25 Gy given to a target volume encompassing the larynx and regional neck nodes, given in 5 equal daily fractions of 5 Gy in 5 consecutive days. Surgery was performed 2 days later. Total laryngectomy was performed on 48 patients, total laryngectomy with neck dissection on 55 patients, supraglottic laryngectomy on 5 and supraglottic laryngectomy with neck dissection on 2 patients. Crude actuarial 5 and 10 year survival probability for the whole group is 71 and 61%, respectively. The corrected 5 and 10 year survival is 75%. For patients with T/sub 3/-T/sub 4/-N/sub 0/ tumors 5 and 10 year survival probability is: crude 65 and 58%, and corrected 70% respectively. For T/sub 3/-T/sub 4/-N/sub +/ crude: 75 and 60% and corrected: 78%. Of 110 patients, one died postoperative, three died of intercurrent disease, five died as a result of second malignancy, and 23 died of their larynx carcinoma: 12/23 because of locoregional failure, and 11/23 because of distant metastasis. We concluded that short intensive preoperative radiation therapy and surgery offer a high cure rate in the treatment of advanced resectable laryngeal carcinoma. The merits of this technique are outlined in the text.

    Organ preservation treatment for advanced head and neck squamous cell carcinoma is associated with poor outcomes due to locoregional recurrences. Salvage surgery is the main therapeutic option for some of these patients. The aim of this study was to analyse the results of salvage surgery for advanced pharyngolaryngeal squamous cell carcinoma previously treated with radiochemotherapy. We performed a retrospective study on 38 patients (36 men, 2 women). The median age at diagnosis was 60 years with a mean follow-up period of 49.8 months. Recurrences were diagnosed at a mean of 395 days after finalising organ preservation treatment. Patients went under different salvage surgeries, including 22 total laryngectomies, 6 partial laryngectomies (3 transoral laser surgeries and 3 opened surgeries), 8 functional neck dissections and 2 tongue base surgeries. Nineteen patients had no postoperative complications after a mean hospital stay of 2 weeks. However, 5 patients died of significant recurrent bleedings. There were 4 salivary fistulas that responded to conservative management, while 7 patients had important pharyngostomas that required reconstruction with either regional or free flaps. The mean hospital stay was of 61.60 days for all patients. Five-year overall survival from diagnosis, overall survival after salvage surgery and survival after salvage surgery were 44.20, 37.90 and 45.70%, respectively. In summary, we conclude that salvage surgery is an optimal treatment for pharyngolaryngeal and regional recurrences and provides improvement in locoregional control and survival, despite the severe complications.

    A 58-year-old woman was referred to our hospital with high fever and right upper abdominal pain. Abdominal computed tomography (CT) revealed a bulky tumor of the gallbladder with liver invasion, metastases to para-aortic lymph nodes, and extensive infiltration to Glisson's sheath. The tumor was initially considered to be unresectable locally advanced gallbladder carcinoma with inflammation, and she received 6 courses of chemotherapy with gemcitabine plus cisplatin. Subsequently, the inflammation was extinguished, and CT showed the main tumor shrunk and the Glisson's sheath infiltration disappeared; however, a liver metastasis existed in segment 5. Thus, S4a plus S5 hepatic segmentectomy with extrahepatic bile duct resection and regional and para-aortic lymphadenectomy was performed. The pathological diagnosis was pT3a, pN1, pM1 (Hep, LYM), fStage ⅣB. Curative resection was then performed. If selected according to their response to downsizing chemotherapy, conversion therapy might therefore be an effective multidisciplinary treatment for patients with initially unresectable locally advanced gallbladder carcinoma.

    A therapeutic alternative to exenteration for large locally advanced vulvar carcinoma involving the rectum, anus, or vagina is the use of preoperative radiation followed by radical surgery. Between 1980 and 1988, 13 patients with Stage III and 3 with Stage IV vulvar carcinoma involving the rectum/anus, urethra, or vagina were treated with 4000 rad to the vulva and 4500 rad to the inguinal and pelvic nodes followed by a radical vulvectomy and inguinal lymphadenectomy 4 weeks later. The overall 5 year cumulative survival was 45%. Twelve tumors regressed after radiation with 62.5% of the patients having visceral preservation while in 4 patients there was no major response to radiation and urinary or fecal diversion was required. Of the 6 recurrences 4 were central and 2 distant. Three patients with central recurrences had tumor within 1 cm of the vulvectomy margin. Complications included wet desquamation, inguinal wound separation, lymphedema, and urethral strictures. There were no operative deaths. It is concluded that the use of preoperative radiation followed by radical vulvectomy may be an alternative to pelvic exenteration in selected patients with advanced vulvar lesions.

    Abstract To evaluate the treatment efficacies and toxicities of concurrent cetuximab-based bioradiotherapy (BRT) or cisplatin-based chemoradiotherapy (CRT) in locally advanced nasopharyngeal carcinoma. :Patients with previously untreated locally advanced nasopharyngeal carcinoma were matched into pairs, and enrolled into the study. All patients were given either BRT or CRT. Survival outcomes, toxicities, and prognostic factors were evaluated. :A total of 112 patients were enrolled. The 5-year overall survival was 79.3% and 79.5% in CRT and BRT arm, respectively (P = 0.797) and the 5-year DFS was 73.5% and 74.6%, respectively (P = 0.953). In toxicity analysis, CRT arm had more significant decrease in white blood cell, platelet, hemoglobin, and severe vomiting, while more severe skin reactions and mucositis were shown in BRT arm. :BRT was not less efficacious than traditional CRT. They lead to different aspects of toxicities. If patients cannot stand more severe toxicities caused by CRT, BRT could be an ideal alternative. PMID:27684830

    Cancer of the uterine cervix is one of the leading causes of cancer death among women worldwide. The estimated new cancer cervix cases per year is 500,000 of which 79% occur in the developing countries. Cancer cervix occupies either the top rank or second among cancers in women in the developing countries, whereas in the affluent countries cancer cervix does not even find a place in the top 5 leading cancers in women. The truncated rate (TR) in the age group 35-64 years in Chennai, India, is even higher (99.1/100,000; 1982-95) than rate reported from Cali, Colombia (77.4/100,000, 1987-91). The cervical cancer burden in India alone is estimated as 100,000 in 2001 AD. The differential pattern of cervical cancer and the wide variation in incidence are possibly related to environmental differences. Aetiologic association and possible risk factors for cervical carcinoma have been extensively studied. The factors are: Sexual and reproductive factors, socio-economic factors (education and income), viruses e.g., herpes simplex virus (HSV), human papillomavirus (HPV), human immunodeficiency virus (HIV) in cervical carcinogenesis and other factors like smoking, diet, oral contraceptives, hormones, etc. The accumulated evidence suggests that cervical cancer is preventable and is highly suitable for primary prevention. Sexual hygiene, use of barrier contraceptives and ritual circumcision can undoubtedly reduce cervical cancer incidence. Education, cervical cancer screening of high risk groups and improvement in socio-economic status can reduce cervical cancer morbidity and mortality significantly.

    Cutaneous basal cell carcinoma (BCC) is the most common human cancer and its incidence is rising worldwide. Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449), a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA)-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery. PMID:26604681

    Basal cell carcinoma (BCC) is a common malignancy with a good prognosis in the majority of cases. However, some BCC patients develop a more advanced disease that poses significant management challenges. Such cases include locally advanced, recurrent or metastatic BCC, or tumours that occur in anatomical sites where surgical treatment would result in significant deformity. Until recently, treatment options for these patients have been limited, but increased understanding of the molecular basis of BCC has enabled potential therapies, such as hedgehog signalling pathway inhibitors, to be developed. A clear definition of advanced BCC as a distinct disease entity and formal management guidelines have not previously been published, presumably because of the rarity, heterogeneity and lack of treatment options available for the disease. Here we provide a UK perspective from a multidisciplinary group of experts involved in the treatment of complex cases of BCC, addressing the key challenges associated with the perceived definition and management of the disease. With new treatments on the horizon, we further propose a definition for advanced BCC that may be used as a guide for healthcare professionals involved in disease diagnosis and management.

    The roles of Wnt protein in carcinogenesis have been well documented in human cancers. Wls is a key modulator for the secretion of Wnt protein. We previously found that Wls was aberrantly expressed in colorectal carcinomas. Studies have revealed that dysregulation of Wnt signal transduction plays an important role in gastric carcinoma. We hypothesized that Wls may play a role in the development and progression of gastric carcinoma. In this study, three gastric cancer cell lines MGC-803, SGC-7901, and AGS, and a set of gastric carcinoma tissue specimens were subjected to immunohistochemistry. The relationship between the expression of Wls and clinicopathological parameters was analyzed. Wls was negatively detected in MGC-803, positively detected in SGC-7901 and AGS cell lines. Wls was weakly expressed in 9.7% (15/154), moderately in 33.1% (51/154), and strongly in 57.1% (88/154) of tested gastric carcinoma specimens. High expression of Wls was positively associated with well and moderately differentiated tumors (P = 0.035, rs  = 0.170), lymph node metastasis (P = 0.001, rs  = 0.276), and advanced TNM stage (P = 0.006, rs  = 0.219). Our data suggest that Wls protein is related to tumor metastasis and advanced TNM stage, and may be used as a new marker for prognosis of gastric carcinoma.

    Objectives: Oral cancer represents a health burden worldwide. Up to 90% of oral cancer cases are squamous cell carcinomas (SCC). The data on oral SCC in Yemen are lacking. The objective of this study therefore was to describe and analyze the demographic, clinical and histological characteristics of Yemeni patients with oral SCC. Study Design: In this cross-sectional study, two sets of retrospective data for Yemeni cancer patients were obtained officially by two different registries. Patients with oral SCC were included. Their ages were dichotomized using 40 and 45 years alternately as individual cut-points for young and old patients. The patients` demographic, clinical and histological characteristics were statistically analyzed. Results: There were 457 Yemenis with oral SCC; 253 patients (55.4%) were men. The overall mean age was 58.15±14.11 years. The tongue was the most affected oral sub-site accounting for 53% of the reported cases. The well and moderately differentiated oral SCC accounted for 55.5% and 25.6% of the total cases respectively. Noteworthy, 62 patients (14%) were affected by the age of ?40; this increased to 105 patients (23%) aged ?45 years. Additionally, a high proportion of oral SCC patients (62%, 283) were diagnosed at advanced tumor stages (regional extension or metastasized). The distributions of histological grades and tumor stages in young and old patients were significantly different (P=0.006 and 0.026 respectively). Conclusion: The relative frequency of oral SCC among Yemeni young people is high. Unfortunately, most of oral SCC patients in Yemen were diagnosed at advanced stage. Key words:Oral squamous cell carcinoma, Yemen, young patients, advanced stage. PMID:24558559

    Alternative therapies have been sought to alleviate mutilation and morbidity associated with surgery for vulvar neoplasms. Our prime objective was to assess tumor absence in pathological vulvar and nodal specimens following neoadjuvant chemoradiotherapy in locally advanced vulvar neoplasms. Data were retrospectively collected from January 2001 to May 2009 from 22 patients treated with neoadjuvant therapy for locally advanced squamous cell carcinoma of the vulva. Neoadjuvant treatment consisted of inguino-pelvic radiotherapy (50 Gy) in association with chemotherapy when possible. Surgery occurred at intervals of between 5 to 8 weeks. The median age of patients at diagnosis was 74.1 years. All patients were primarily treated with radiotherapy and 15 received a concomitant chemotherapy. Additionally, all patients underwent radical vulvectomy and bilateral inguino-femoral lymphadenectomy. Tumor absence in the vulvar and nodal pathological specimens was achieved for 6 (27%) patients, while absence in the vulvar pathological specimens was only achieved for 10 (45.4%) patients. Postoperative follow-up revealed breakdown of groin wounds, vulvar wounds and chronic lymphedema in 3 (14.3%), 7 (31.8%) and 14 cases (63.6%), respectively. Within a median follow-up time of 2.3 years [interquartile range (IQR), 0.6-4.6], 12 (54.6%) patients experienced complete remission and 6 cases succumbed to metastatic evolution within a median of 2.2 years (IQR, 0.6-4.6), with 1 case also experiencing perineal recurrence. Median survival time, estimated using the Kaplan-Meier method, was 5.1 years (IQR, 1.0-6.8). We suggest that neoadjuvant chemoradiotherapy may represent a reliable and promising strategy in locally advanced squamous cell carcinoma of the vulva.

Data were retrospectively collected from January 2001 to May 2009 from 22 patients treated with neoadjuvant therapy for locally advanced squamous cell carcinoma of the vulva. Neoadjuvant treatment consisted of inguino-pelvic radiotherapy (50 Gy) in association with chemotherapy when possible. Surgery occurred at intervals of between 5 to 8 weeks. The median age of patients at diagnosis was 74.1 years. All patients were primarily treated with radiotherapy and 15 received a concomitant chemotherapy. Additionally, all patients underwent radical vulvectomy and bilateral inguino-femoral lymphadenectomy. Tumor absence in the vulvar and nodal pathological specimens was achieved for 6 (27%) patients, while absence in the vulvar pathological specimens was only achieved for 10 (45.4%) patients. Postoperative follow-up revealed breakdown of groin wounds, vulvar wounds and chronic lymphedema in 3 (14.3%), 7 (31.8%) and 14 cases (63.6%), respectively. Within a median follow-up time of 2.3 years [interquartile range (IQR), 0.6–4.6], 12 (54.6%) patients experienced complete remission and 6 cases succumbed to metastatic evolution within a median of 2.2 years (IQR, 0.6–4.6), with 1 case also experiencing perineal recurrence. Median survival time, estimated using the Kaplan-Meier method, was 5.1 years (IQR, 1.0–6.8). We suggest that neoadjuvant chemoradiotherapy may represent a reliable and promising strategy in locally advanced squamous cell carcinoma of the vulva. PMID:23205089

    Purpose: To evaluate the efficacy of an adjuvant radiotherapy after transoral laser microsurgery for advanced squamous cell carcinoma of the head and neck and to show that a less invasive surgery with organ preservation in combination with radiotherapy is an alternative to a radical treatment. Patients and Methods: Between 1987 and 2000, 208 patients with advanced squamous cell carcinoma of the head and neck were treated with postoperative radiotherapy after surgical CO{sub 2} laser resection. Primary sites included oral cavity, 38; oropharynx, 88; larynx, 36; hypopharynx, 46. Disease stages were as follows: Stage III, 40 patients; Stage IV, 168 patients. Before 1994, the treatment consisted of a split-course radiotherapy with carboplatinum (Treatment A). After 1994, the patients received a conventional radiotherapy (Treatment B). Results: Patients had 5-year locoregional control and disease-specific survival (DSS) rates of 68% and 48%, respectively. The 5-year DSS was 70% and 44% for Stages III and IV, respectively (p = 0.00127). Patients treated with a hemoglobin level greater or equal to 13.5 g/dL before radiotherapy had a 5-year DSS of 55% as compared with 39% for patients treated with a hemoglobin level greater than 13.5 g/dL (p = 0.0054). Conclusion: In this series of patients with advanced head-and-neck tumors, transoral laser surgery in combination with adjuvant radiotherapy resulted in locoregional control and DSS rates similar to those reported for radical surgery followed by radiotherapy. Treatment B has clearly been superior to Treatment A. A further improvement of our treatment regimen might be expected by the combination of adjuvant radiotherapy with concomitant platinum-based chemotherapy.

  17. A unique bleeding-related complication of sorafenib, a tyrosine kinase inhibitor, in advanced hepatocellular carcinoma: a case report

    PubMed Central

    2014-01-01

    Introduction Sorafenib, a multikinase inhibitor as a standard of care for advanced hepatocellular carcinoma, may lead endothelial cells to an unstable state by blocking the signaling pathway of vascular endothelial growth factor receptor, which may result in the disruption of the architecture and integrity of the microvasculature, and eventually increase the risk of hemorrhage. Hemobilia is a relatively uncommon condition as a consequence of hepatocellular carcinoma and its risk factors remain uncertain. Case presentation Here we report a unique case of hemobilia occurring in a 55-year-old Korean man with hepatitis B virus-related hepatocellular carcinoma on Barcelona Clinic Liver Cancer advanced stage after seven days of treatment with sorafenib. He had received prior radiation therapy. Endoscopy revealed bleeding from the major duodenal papilla and endoscopic retrograde cholangiography revealed an amorphous filling defect throughout the common bile duct. Blood clots were removed by balloon sweeping and a nasobiliary drainage tube was placed. No further bleeding has been detected as of eight months after discontinuation of sorafenib. Conclusion Sorafenib may increase the risk of biliary bleeding in hepatocellular carcinoma patients who were primed with irradiation, by blocking the signaling pathway of the vascular endothelial growth factor receptor. Therefore, sorafenib should be used with caution in patients with advanced hepatocellular carcinoma, especially when combined with radiation therapy. PMID:24571585

    A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

    Incomplete characterization of the uterine cervix cancer from molecular point of view represents the main problem for the use of a proper therapy in this disease. Few data are available about D2-40 expression in lymphatic endothelial cells and also in tumor cells from uterine cervix cancer. The aim of the present work was to study the involvement of lymphatics in prognosis and tumor progression of the uterine cervix lesions. We used D2-40 immunostaining to highlight lymphatic vessels from squamous cell metaplasia (n=17), cervical intraepithelial neoplasia (n=11), carcinoma in situ (n=3), microinvasive carcinoma (n=4) and invasive carcinoma (n=19) using Avidin-Biotin technique (LSAB+). Type and distribution of lymphatics in different lesions of the cervix were analyzed. We found significant correlation between lymphatic microvessel density and tumor grade and particular distribution of the lymphatics linked to histopathologic type of the lesions. Also, differences was found in lymphovascular invasion interpretation between routine Hematoxylin and Eosin staining specimens and immunohistochemical ones. Our results showed differences in the distribution and D2-40 expression in lymphatic vessels and tumor cells from the cervix lesions linked to histopathology and tumor grade.

    Advanced penile squamous cell carcinoma (PSCC) is associated with poor survival due to the aggressiveness of the disease and lack of effective systemic therapies. Comprehensive genomic profiling (CGP) was performed to identify clinically relevant genomic alterations (CRGAs). DNA was extracted from 40 μm of formalin-fixed, paraffin-embedded sections in patients with advanced PSCC. CGP was performed on hybridization-captured, adaptor ligation-based libraries to a mean coverage depth of 692× for 3,769 exons of 236 cancer-related genes plus 47 introns from 19 genes frequently rearranged in cancer. CRGAs were defined as genomic alterations (GAs) linked to targeted therapies on the market or under evaluation in mechanism-driven clinical trials. Twenty male patients with a median age of 60 years (range, 46-87 years) were assessed. Seventeen (85%) cases were stage IV and three cases (15%) were stage III. CGP revealed 109 GAs (5.45 per tumor), 44 of which were CRGAs (2.2 per tumor). At least one CRGA was detected in 19 (95%) cases, and the most common CRGAs were CDKN2A point mutations and homozygous deletion (40%), NOTCH1 point mutations and rearrangements (25%), PIK3CA point mutations and amplification (25%), EGFR amplification (20%), CCND1 amplification (20%), BRCA2 insertions/deletions (10%), RICTOR amplifications (10%), and FBXW7 point mutations (10%). CGP identified CRGAs in patients with advanced PSCC, including EGFR amplification and PIK3CA alterations, which can lead to the rational administration of targeted therapy and subsequent benefit for these patients. Few treatment options exist for patients with advanced penile squamous cell carcinoma (PSCC). Outcomes are dismal with platinum-based chemotherapy, with median survival estimated at 1 year or less across multiple series. Biological studies of patients with PSCC to date have principally focused on human papillomavirus status, but few studies have elucidated molecular drivers of the disease. To this end

    Because many patients with unresectable basal cell carcinoma (BCC) are aged ≥65 years, this study explores the efficacy and safety of vismodegib in these patients with locally advanced (la) or metastatic (m) basal cell carcinoma (BCC) in the ERIVANCE BCC trial and the expanded access study (EAS).We compared patients aged ≥65 years to patients aged <65 years taking vismodegib 150 mg/day, using descriptive statistics for response and safety. Patients aged ≥65 years (laBCC/mBCC) were enrolled in ERIVANCE BCC (33/14) and EAS (27/26). Investigator-assessed best overall response rate in patients ≥65 and <65 years was 46.7%/35.7% and 72.7%/52.6% (laBCC/mBCC), respectively, in ERIVANCE BCC and 45.8%/33.3% and 46.9%/28.6%, respectively, in EAS. These differences were not clinically meaningful. Safety was similar in both groups, although those aged ≥65 years had a higher percentage of grade 3-5 adverse events than those aged <65 years. Vismodegib demonstrated similar clinical activity and adverse events regardless of age. PMID:27764798

    Head and neck carcinomas have long been linked to alcohol and tobacco abuse; however, within the last two decades, the human papillomavirus (HPV) has emerged as a third etiology and is specifically associated with head and neck squamous cell carcinomas (HNSCC). In this anatomical region, the oncogenic HPV-16 mediates transformation and immortalization of epithelium, most commonly in the oropharynx. Nevertheless, the recent identification of novel HPV mechanisms thought to be specific to oropharyngeal carcinogenesis has coincided with observations that HPV-associated HNSCC has differing clinical behavior—in terms of natural history, therapeutic response, and prognosis—than HPV-negative head and neck tumors. Taken together with the growing incidence of HPV transmission in younger populations, these discoveries have sparked a rapid expansion in both laboratory and clinical studies on the infection and disease. Herein, we review the clinical characteristics of HPV-associated HNSCC, with particular emphasis on recent advancements in our understanding of the management of this infectious malignancy.

    2016-01-01

    The treatment of metastatic renal cell carcinoma (mRCC) is rapidly changing. During first-line treatment with targeted therapy, patients ultimately develop resistance to therapy and the disease progresses. Recently, cabozantinib has demonstrated a better response rate, progression-free survival and overall survival compared with everolimus after failure of prior targeted therapy in patients with advanced or metastatic renal cell carcinoma (RCC). Cabozantinib is a small-molecule tyrosine kinase inhibitor (TKI). It exerts inhibition of MET, vascular endothelial growth factor receptor type 2, AXL, and many other receptor tyrosine kinases that are also implicated in tumor pathobiology, including RET, KIT, and FLT3. MET drives tumor survival, invasion, angiogenesis, and metastasis through several downstream signaling pathways. AXL has recently been described as an essential mediator of cancer metastasis that mediates crosstalk and resistance to TKIs. MET and AXL are thought to be anti-vascular endothelial growth factor receptor (VEGF) resistance pathways and thus cabozantinib represents a logical choice after progression on initial VEGF therapy. Subgroup analyses examining those with good performance status or visceral and bone metastases indicate that the hazard ratios may be better when using cabozantinib versus everolimus. However, there were no clear statistically significant differences between any subgroups. PMID:27904650

    Primary liver cancer is one of the commonest causes of death. Hepatocellular carcinoma (HCC) accounts for 90% of primary liver cancers. For patients with unresectable or metastatic HCC, conventional chemotherapy is of limited or no benefit. Sorafenib is the only systemic treatment to demonstrate a statistically significant but modest overall survival benefit, leading to an era of targeted agents. Many clinical trials of targeted drugs have been carried out with many more in progress. Some drugs like PTK787 showed potential benefits in the treatment of HCC. Despite these promising breakthroughs, patients with HCC still have a dismal prognosis. Recently, both a phase III trial of everolimus and a phase II clinical trial of trebananib failed to demonstrate effective antitumor activity in advanced HCC. Sorafenib still plays a pivotal role in advanced HCC, leading to further explorations to exert its maximum efficacy. Combinations targeted with chemotherapy or transarterial chemoembolization is now being tested and might bring about advances. New targeted agents such as mammalian target of rapamycin inhibitors are under investigation, as well as further exploration of the mechanism of hepatocarcinogenesis. PMID:25914779

    Objective: To investigate the outcome of locoregionally advanced nasopharyngeal carcinoma (NPC) treated with induction chemotherapy followed by chemoradiotherapy. Methods: Between June 2005 and October 2007, 604 patients with locoregionally advanced NPC were analyzed, of whom 399 and 205 were treated with conventional radiotherapy and intensity-modulated radiotherapy (IMRT) respectively. Meanwhile, 153 patients received concurrent chemotherapy, and 520 were given induction chemotherapy. Results: With a median follow-up time of 65 months, the 3-, and 5-year overall survival (OS), locoregional free survival (LRFS), and distant-metastasis free survival (DMFS) rates were 82.5% vs. 72.6%, 90.6% vs. 87.1%, and 82.5% vs. 81.2%, respectively. Induction chemotherapy was not an independent prognostic factor for OS (P=0.193) or LRFS, but there was a positive tendency for DMFS (P=0.088). GP regimen (gemcitabine + cisplatin) was an independent prognostic factor for OS (P = 0.038) and it had a trend toward improved DMFS (P = 0.109). TP regimen (taxol + cisplatin) was only a significant prognostic factor for DMFS (P =0.038). Conclusions: Adding induction chemotherapy had no survival benefit, but GP regimen benefited overall survival and had a trend toward improved DMFS. GP regimen may be superior to TP/FP regimen (fluorouracil + cisplatin) in treating locoregionally advanced NPC. PMID:26430402

    Background/Aims We investigated the effects of sorafenib monotherapy on advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT) in a clinical setting. Methods In total, 143 consecutive patients with unresectable HCC were treated with sorafenib. Among these patients, 30 patients with advanced HCC and PVTT (Vp3 or 4) were treated with sorafenib monotherapy. Results All patients had a performance status of 1 to 2 (Eastern Cooperative Oncology Group 1/2, 20/10) and Child-Pugh class A or B (A/B, 17/13). Eleven patients had modified Union for International Cancer Control stage IVA tumors, whereas 19 had stage IVB tumors. All patients had PVTT (Vp3, 6; Vp4, 24). Following sorafenib monotherapy, three patients (10.0%) had a partial response with PVTT revascularization, and nine (30.0%) had stable disease, with a disease control rate of 33.3%. The median overall survival was 3.1 months (95% confidence interval [CI], 2.70 to 3.50), and the median progression-free survival was 2.0 months (95% CI, 1.96 to 2.05). Fatigue and hand-foot skin reactions were the most troublesome side effects. Conclusions A limited proportion of patients with advanced HCC and PVTT exhibited a remarkable outcome after sorafenib monotherapy, although the treatment results in this type of patient is extremely poor. Further studies to predict good responders to personalized therapy are warranted. PMID:24312711

    We aimed to identify optimal machine-learning methods for radiomics-based prediction of local failure and distant failure in advanced nasopharyngeal carcinoma (NPC). We enrolled 110 patients with advanced NPC. A total of 970 radiomic features were extracted from MRI images for each patient. Six feature selection methods and nine classification methods were evaluated in terms of their performance. We applied the 10-fold cross-validation as the criterion for feature selection and classification. We repeated each combination for 50 times to obtain the mean area under the curve (AUC) and test error. We observed that the combination methods Random Forest (RF) + RF (AUC, 0.8464 ± 0.0069; test error, 0.3135 ± 0.0088) had the highest prognostic performance, followed by RF + Adaptive Boosting (AdaBoost) (AUC, 0.8204 ± 0.0095; test error, 0.3384 ± 0.0097), and Sure Independence Screening (SIS) + Linear Support Vector Machines (LSVM) (AUC, 0.7883 ± 0.0096; test error, 0.3985 ± 0.0100). Our radiomics study identified optimal machine-learning methods for the radiomics-based prediction of local failure and distant failure in advanced NPC, which could enhance the applications of radiomics in precision oncology and clinical practice.

    Recent advances in understanding the fundamental biology underlying clear-cell RCC have opened the door to a series of targeted agents, such as tyrosine kinase inhibitors (TKIs) or mTOR inhibitors. These new agents have become the standard of care in managing advanced clear-cell RCC. Choice of initial medical management in patients with metastatic clear-cell RCC should be guided by randomised studies. On the evidence available, the first-line therapy in patients with good- or intermediate-risk mRCC should be either sunitinib or pazopanib, or bevacizumab plus interferon. In selected patients sorafenib is an option, as is high-dose interleukin-2 if performance status is good. In patients with poor prognosis, temsirolimus is recommended. In cytokine refractory patients, sorafenib, when patients have progressed on a tyrosine kinase inhibitor everolimus is the agent of choice. Biró K, Küronya Z.

Lymphocyte, neutrophil and platelet were measured before beginning of treatment and after one month. Patient with SII ≥ 360 showed lower median PFS (2.6 vs. 3.9 months, P < 0.026) and OS (5.6 vs. 13.9 months, P = 0.027) with respect to patients with SII < 360. NLR ≥ 3 had a lower median PFS (2.6 vs. 3.3 months, P < 0.049) but not OS (5.6 vs. 13.9 months, P = 0.062) than those with NLR < 3. After adjusting for clinical covariates SII and NLR remained an independent prognostic factor for OS. The SII and NLR represent potential prognostic indicator in patients with advanced HCC treated with sorafenib. PMID:27613839

    Background Hepatocellular carcinoma (HCC) is a severe health condition associated with high hospitalizations and mortality rates, which also imposes a relevant economic burden. Purpose The aim of the present survey is to investigate treatment strategies and related costs for HCC in the intermediate and advanced stages of the disease. Patients and methods The survey was conducted in four Italian centers through structured interviews with physicians. Information regarding the stage of disease, treatments performed, and related health care resource consumption was included in the questionnaire. Direct health care cost per patient associated with the most relevant treatments such as sorafenib, transarterial chemoembolization (TACE), and transarterial radioembolization (TARE) was evaluated. Results Between 2013 and 2014, 285 patients with HCC were treated in the four participating centers; of these, 80 were in intermediate stage HCC (Barcelona Clinic Liver Cancer Classification [BCLC] B), and 57 were in the advanced stage of the disease (BCLC C). In intermediate stage HCC, the most frequent first-line treatment was TACE (63%) followed by sorafenib (15%), radiofrequency ablation (14%), and TARE (1.3%). In the advanced stage of HCC, the most frequently used first-line therapy was sorafenib (56%), followed by best supportive care (21%), TACE (18%), and TARE (3.5%). The total costs of treatment per patient amounted to €12,214.54 with sorafenib, €13,418.49 with TACE, and €26,106.08 with TARE. Both in the intermediate and in the advanced stage of the disease, variability in treatment patterns among centers was observed. Conclusion The present analysis raises for the first time the awareness of the overall costs incurred by the Italian National Healthcare System for different treatments used in intermediate and advanced HCC. Further investigations would be important to better understand the effective health care resource usage. PMID:26527877

    Background: Advanced hepatocellular carcinoma (HCC) is a malignancy of global importance: it is the sixth most common cancer and the third most common cause of cancer-related mortality worldwide. Despite decades of efforts by many investigators, systemic chemotherapy or hormone therapy has failed to demonstrate improved survival in patients with HCC.. Ongoing studies are evaluating the efficacy and tolerability of combining Sorafenib with erlotinib and other targeted agents or chemotherapy. Aims: On the basis of placebo-controlled, randomized phase III trials, Sorafenib has shown improved survival benefits in advanced HCC and has set a new standard for future clinical trials. The successful clinical development of Sorafenib in HCC has ushered in the era of molecularly targeted agents in this disease, which is discussed in this educational review. Material and Methods: Many molecularly targeted agents that inhibit angiogenesis, epidermal growth factor receptor, and mammalian target of rapamycin are at different stages of clinical development in advanced HCC. Future research should continue to unravel the mechanism of hepatocarcinogenesis and to identify key relevant molecular targets for therapeutic intervention. Identification and validation of potential surrogate and predictive biomarkers hold promise to individualize patients’ treatment to maximize clinical benefit and minimize the toxicity and cost of targeted agents. Results: Systemic therapy with various classes of agents, including hormone and cytotoxic agents, has provided no or marginal benefits. Improved understanding of the mechanism of hepatocarcinogenesis, coupled with the arrival of many newly developed molecularly targeted agents, has provided the unique opportunity to study some of these novel agents in advanced HCC. Conclusions: The demonstration of improved survival benefits by Sorafenib in advanced HCC has ushered in the era of molecular-targeted therapy in this disease, with many agents

    Sorafenib, an oral multikinase inhibitor, is approved for advanced hepatocellular carcinoma (HCC) treatment. However, its therapeutic effect in advanced HCC patients with extrahepatic metastasis remains uncertain. This study aimed to prospectively assess the efficacy, safety, and survival risk factors and evaluate the prognostic impact of sorafenib treatment in advanced HCC patients with or without extrahepatic metastasis. Between May 2009 and March 2014, 312 consecutive advanced HCC patients who received sorafenib were enrolled in this study. We evaluated their characteristics and compared the clinical outcomes of those with and without extrahepatic metastasis. Of the enrolled patients, 245 (81%) received sorafenib treatment for more than 1 month, with a median duration of 3.6 months. Eighteen patients demonstrated partial response to sorafenib therapy, 127 had stable disease, and 134 had progressive disease at the first radiologic assessment. The median survival time (MST) and progression-free survival (PFS) were 10.3 and 3.6 months, respectively. Multivariate analysis identified gender, Child-Pugh class, baseline serum des-gamma-carboxy prothrombin level, and treatment duration as independent risk factors for survival. Extrahepatic metastasis was detected in 178 patients. However, the MST, PFS, and therapeutic effect were comparable between patients with and without extrahepatic metastasis. The independent risk factors for decreased overall survival in patients with extrahepatic metastasis were similar to those affecting all patients. Our results indicated that sorafenib could be administered for hepatic reserve and as long-term treatment for advanced HCC patients regardless of their extrahepatic metastasis status. © 2015 The Authors.

    Fifty-one patients (32 previously untreated, 19 previously treated) with advanced squamous cell carcinoma of the head and neck received a single course of combination chemotherapy consisting of high dose cis-platinum (DDP), bleomycin (Bleo), +/- high dose methotrexate (MTX). Thirty-three (65%) patients responded to therapy; 5 (10%) of these patients had a complete response. Previously untreated patients and those who received the three drugs (DDP, Bleo and MTX) had the highest response rates. The duration of response was 8 to 12 weeks. Seven (15%) patients showed a two-year survival rate. All nonresponders were dead of disease within two years. Three (56%) of the five complete-response patients and 4 (21%) of the partial-response patients survived for two years. The role of preoperative chemotherapy in head and neck cancer is yet to be conclusively defined.

    Prognosis of advanced oral squamous cell carcinoma remains a challenge for clinicians despite progress in its diagnosis and treatment over the past decades. In this review, we assessed clinicopathological factors and potential biomarkers along with their prognostic relevance in an attempt to develop optimal treatment strategies for these patients. In addition to several pathologic factors that have been proposed to improve prognostic stratification and treatment planning in the eighth edition of the American Joint Committee staging manual on cancer, we reviewed some other imaging and clinicopathological parameters demonstrated to be closely associated with patient prognosis, along with the biomarkers related to novel target or immune therapy. Evaluation of current literature regarding the prognostic stratification used in contemporary clinicopathological studies and progress in the development of targeted or immune therapy may help these patients benefit from tailored and personalized treatment and obtain better oncological results.

    Lung cancer remains the single deadliest cancer both in the US and worldwide. The great majority of squamous cell carcinoma (SCC) is attributed to cigarette smoking, which fortunately is declining alongside cancer incidence. While we have been at a therapeutic plateau for advanced squamous cell lung cancer patients for several decades, recent observations suggest that we are on the verge of seeing incremental survival improvements for this relatively large group of patients. Current studies have confirmed an expanding role for immunotherapy [including programmed cell death-1 (PD-1)/programmed cell death ligand 1 (PD-L1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibition], a potential opportunity for VEGFR inhibition, and even future targets in fibroblast growth factor receptor (FGFR) and PI3K-AKT that collectively should improve survival as well as quality of life for those affected by squamous cell lung cancer over the next decade.

    Background: Peritoneal tuberculosis accounts 1-2% of all forms of tuberculosis. Peritoneal tuberculosis is an important differential diagnosis for ovarian cancer in women with ascites, adnexal mass and elevated cancer antigen 125 (CA125) levels. We report a case of a 32- year -old woman with multiple miliary peritoneal deposits mimicking advanced ovarian carcinoma. Case Presentation: A 32-year-old drug addicted woman presented with menometrorrhagia, fever and shivering, ascites and pelvis mass. Ultrasonography revealed a 53×65 mm cyst in left ovary and ascites. Multiple miliary peritoneal deposits were observed during laparatomy without any mass, histologic examination confirmed tuberculosis of uterus, tubes, omentum, liver and external surfaces of small intestine. Finally, the patient recovered with anti-tuberculosis treatment. Conclusion: These findings highlight considering tuberculosis in the differential diagnosis of any patients with adnexal mass, ascitis and elevated serum CA125 even with negative cytology and bacteriology test results.

    Despite advances in metastatic renal cell carcinoma (mRCC) treatments, patients eventually progress and develop resistance to therapies targeting a single pathway. Lenvatinib inhibits VEGFR1-3, FGFR1-4, PDGFRβ, RET and KIT proto-oncogenes. In a randomized, Phase II trial evaluating patients with mRCC who had progressed after one prior VEGF-targeted therapy, progression-free survival was significantly improved with lenvatinib alone or in combination with everolimus versus everolimus alone. This review summarizes the clinical development of lenvatinib in mRCC, and how simultaneous targeting of multiple pathways involved in carcinogenesis and/or therapeutic resistance may improve patient outcomes. Lenvatinib plus everolimus may be a promising second-line treatment in patients with mRCC.

    Hepatocellular carcinoma is the fastest growing cause of cancer related death globally. Sorafenib, a multi-targeted kinase inhibitor, is the only drug proven to improve outcomes in patients with advanced disease offering modest survival benefit. Although comprehensive genomic mapping has improved understanding of the genetic aberrations in hepatocellular cancer (HCC), this knowledge has not yet impacted clinical care. The last few years have seen the failure of several first and second line phase III clinical trials of novel molecularly targeted therapies, warranting a change in the way new therapies are investigated in HCC. Potential reasons for these failures include clinical and molecular heterogeneity, trial design and a lack of biomarkers. This review discusses the current crisis in HCC drug development and how we should learn from recent trial failures to develop a more effective personalised treatment paradigm for patients with HCC.

    Basal cell carcinomas (BCCs) are the commonest malignancy in the Western world. Locally advanced BCCs (laBCCs) represent tumours that have developed in difficult-to-treat facial sites, aggressively recurrent tumours, large neglected tumours and those in which current treatment options are excluded by clinical or patient-driven criteria. It is estimated laBCCs represent 1% of BCCs. Sonidegib is an oral hedgehog pathway inhibitor with a novel structure. It has recently been licensed for the treatment of laBCC. This article provides a comprehensive review of the literature regarding sonidegib, detailing the pharmacology of the compound, clinical trial data, competitor compounds and a future perspective. Expert commentary: Sonidegib is a novel smoothened (SMO) inhibitor with comparable efficacy to vismodegib, with patient response rates of 44% (sonidegib) and 43% (vismodegib). The adverse effect profile of these two treatments is similar with the main effects being considered to be class effects of SMO inhibitors.

    The hedgehog (Hh) signaling pathway has been identified as important to normal embryonic development in living organisms and it is implicated in processes including cell proliferation, differentiation and tissue patterning. Aberrant Hh pathway has been involved in the pathogenesis and chemotherapy resistance of different solid and hematologic malignancies. Basal cell carcinoma (BCC) and medulloblastoma are two well-recognized cancers with mutations in components of the Hh pathway. Vismodegib has recently approved as the first inhibitor of one of the components of the Hh pathway (smoothened). This review attempts to provide current data on the molecular pathways involved in the development of BCC and the therapeutic options available for the treatment of locally advanced and metastatic BCC, and the new targeted therapies in development.

    Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival. A total of 110 patients with mid-thoracic ESCC who suffered from Ivor-Lewis were enrolled. The CEP55 expression profile of these patients in tumour tissues and corresponding healthy esophageal mucosa (CHEM) was detected by immunohistochemistry and semi-quantitative reverse transcription-polymerase chain reaction analyses. Correlations between CEP55 expression and clinicopathological factors were analyzed using χ2 test. The log-rank test was employed to calculate survival rate. A Cox regression multivariate analysis was performed to determine independent prognostic factors. The results demonstrated that CEP55 expression in ESCC was significantly higher than that of CHEM (P<0.001). Overexpression of CEP55 was significantly associated with differentiation degree (P=0.022), T stage (P=0.019), lymph node metastasis (P=0.033), clinicopathological staging (P=0.002) and tumor recurrence (P=0.021) in locally advanced ESCC patients. In addition, CEP55 overexpression was significantly associated with reduced overall survival of patients after surgery (P=0.012). The 5-year survival rate of patients without CEP55 overexpression was significantly higher than that of patients with CEP55 overexpression (P=0.012). Therefore, these findings suggest that CEP55 overexpression correlates with poor prognosis in locally advanced ESCC patients. PMID:28123547

    Trans-arterial radioembolization (TARE) is a recognized, although not explicitly recommended, experimental therapy for unresectable hepatocellular carcinoma (HCC). A systematic literature review was performed to identify published studies on the use of TARE in intermediate and advanced stages HCC exploring the efficacy and safety of this innovative treatment. Twenty-one studies reporting data on overall survival (OS) and time to progression (TTP), were included in a meta-analysis. The pooled post-TARE OS was 63% (95% CI: 56-70%) and 27% (95% CI: 21-33%) at 1- and 3-years respectively in intermediate stage HCC, whereas OS was 37% (95% CI: 26-50%) and 13% (95% CI: 9-18%) at the same time intervals in patients with sufficient liver function (Child-Pugh A-B7) but with an advanced HCC because of the presence of portal vein thrombosis. When an intermediate and advanced case-mix was considered, OS was 58% (95% CI: 48-67%) and 17% (95% CI: 12-23%) at 1- and 3-years respectively. As for TTP, only four studies reported data: the observed progression probability was 56% (95% CI: 41-70%) and 73% (95% CI: 56-87%) at 1 and 2 years respectively. The safety analysis, focused on the risk of liver decompensation after TARE, revealed a great variability, from 0-1% to more than 36% events, influenced by the number of procedures, patient Child-Pugh stage and treatment duration. Evidence supporting the use of radioembolization in HCC is mainly based on retrospective and prospective cohort studies. Based on this evidence, until the results of the ongoing randomized trials become available, radioembolization appears to be a viable treatment option for intermediate-advanced stage HCC.

    Sorafenib is the current standard treatment for advanced hepatocellular carcinoma (HCC). We analyzed national prescription patterns and treatment outcomes of patients who received sorafenib for advanced HCC. We established a nation-wide cohort of patients who started receiving treatment with sorafenib for advanced HCC between August 2012 and July 2013 from the National Health Insurance Research Database of Taiwan and also retrieved demographic and prescription data. The databases of National Death Registry and Taiwan Cancer Registry were used for survival outcomes and cancer diagnosis information, respectively. A total of 3,293 patients were enrolled. The median overall survival (OS) and time to treatment discontinuation (TTD) of all patients were 6.8 and 2.6 months, respectively. Upon the first prescription of sorafenib, 58.4% of patients received the standard dose (800 mg/day). Among them, 61.9% had subsequent dose reduction. A total of 41.6% of patients initially received lower than standard doses; 36.1% of them had subsequent dose escalation to 800 mg/day. Being male (odds ratio=1.41; p<0.001) and treatment year of 2012 (odds ratio=1.28; p=0.002) were associated with the standard initial dose. Patients who received standard initial dose of sorafenib, compared to patients who received lower initial doses, exhibited longer OS (median of 7.8 vs. 6.6 months, p<0.001) but similar TTD (median of 2.6 vs. 2.9 months, p=0.840). A considerable number of patients with advanced HCC received less than the standard dose of sorafenib. The treatment outcomes in the general population were consistent with those reported in clinical trials. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Chemoradiation is the mainstay of therapy for advanced cervical cancer, with the most effective treatment regimens involving combinations of radiosensitizing agents. However, administration of radiosensitizing chemotherapeutics concurrently with pelvic radiation is not without side effects. The aim of this study was to examine the utility of localized drug delivery as a means of improving drug targeting of radiosensitizing chemotherapeutics to the cervix while limiting systemic toxicities. An initial proof-of-concept study was performed in 14 healthy women following local administration of diazepam utilizing a novel cervical delivery device (CerviPrep™). Uterine vein and peripheral blood samples were collected and diazepam was measured using a GC-MS method. In the follow-up study, gemcitabine was applied to the cervix in 17 women undergoing hysterectomy for various gynecological malignancies. Cervical tissue, uterine vein blood samples, and peripheral plasma were collected, and gemcitabine and its deaminated metabolite 2',2'-difluorodeoxyuridine (dFdU) were measured using HPLC-UV and LC/MS methods. Targeted delivery of diazepam to the cervix was consistent with parent drug detectable in the uterine vein of 13 of 14 women. In the second study, pharmacologically relevant concentrations of gemcitabine (0.01-6.6 nmol/g tissue) were detected in the cervical tissue of 11 of 16 available specimens with dFdU measureable in 15 samples (0.04-8.8 nmol/g tissue). Neither gemcitabine nor its metabolites were detected in the peripheral plasma of any subject. Localized drug delivery to the cervix is possible and may be useful in limiting toxicity associated with intravenous administration of chemotherapeutics for radiosensitization.

    Oesophageal Squamous Cell Carcinoma (ESCC) is one of the two main subtypes of oesophageal cancer, affecting mainly populations in Asia. Though there have been great efforts to develop methods for a better prognosis, there is still a limitation in the staging of this affection. As a result, ESCC is detected at advances stages, when the interventions on the patient do not have such a positive outcome, leading in many cases to recurrence and to a very low 5-year survival rate, causing high mortality. A way to decrease the number of deaths is the use of biomarkers that can trace the advance of the disease at early stages, when surgical or chemotherapeutic methodologies would have a greater effect on the evolution of the subject. The new high throughput omics technologies offer an unprecedented chance to screen for thousands of molecules at the same time, from which a new set of biomarkers could be developed. One of the most convenient types of samples is saliva, an accessible body fluid that has the advantage of being non-invasive for the patient, being easy to store or to process. This review will focus on the current status of the new omics technologies regarding salivaomics in ESCC, or when not evaluated yet, the achievements in related diseases.

    Nimotuzumab is a blocking monoclonal antibody against epidermal growth factor receptor (EGFR). However, little is known about the safety and preliminary efficacy of nimotuzumab combined with concurrent chemoradiotherapy in locally advanced NPC patients. A total of 42 patients diagnosed between 2011 and 2013 were enrolled. Our results demonstrated 38 patients had a complete response (90.5%), 4 patients had a partial response (9.5%). And no patients had progressive disease at early treatment response evaluation, giving an ORR of 100%. The 2-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and overall survival (OS) were 96.4%, 93.1% and 96.6% respectively. The most common adverse events were mucositis (19 patients), hematology toxicity (14 patients) with 6 and 3 cases of grade 3/4 toxicity respectively. Skin rash was not developed in our 43 patients. Thus, nimotuzumab combined with concurrent chemoradiotherapy showed encouraging outcomes in the treatment of locally advanced nasopharyngeal carcinoma, without accumulation of toxicity and well-tolerated.

    Background. Sorafenib has proven survival benefits in patients with advanced hepatocellular carcinoma (HCC). The viability of continuing sorafenib at a higher dosage in patients who experienced radiologic disease progression was investigated. Methods. Patients who experienced disease progression while on sorafenib 400 mg twice daily were randomized to sorafenib 600 mg twice daily (n = 49) or best supportive care (n = 52). The primary end point was progression-free survival (PFS). Time to progression, overall survival, and safety were also evaluated. Results. The study did not meet its primary end point. The difference in PFS between the sorafenib arm (3.91 months) and the best supportive care arm (2.69 months) did not reach statistical significance (p = 0.086). Adverse events were mainly grade 1–2 and similar across both groups. In the sorafenib arm, the most frequent events were diarrhea (80%), weight loss (75%), fatigue (67%), hand-foot-skin reaction (49%), abdominal pain (37%), and stomatitis (26%). Conclusions. Escalated-dose sorafenib in patients with advanced HCC who progressed while on sorafenib, failed to provide any clinical benefit. Second-line treatment still remains an open issue to be explored in appropriate clinical trials. PMID:23580239

    As well known, signet-ring cell carcinoma (SRCC) is a rare histological subtype of colorectal adenocarcinoma, which has been associated with poor prognosis and resistant to non-surgery therapy compared with common adenocarcinoma. In this study, we assessed the effect of preoperative radiotherapy (PRT) for locally advanced rectal SRCC in a large patient group from the Surveillance, Epidemiology, and End Results program (SEER, 1988–2011) database. SRCC was found in 0.9% (n = 622) rectal cancer (RC) patients in our study. In the PRT setting, SRCC had significantly worse cancer-specific survival than mucinous adenocarcinoma and nonmucinous adenocarcinoma patients (log-rank, P < 0.001). In terms of SRCC, stage III RC patients benefited from PRT (log-rank, P < 0.001) while stage II did not (P = 0.095). The multivariate Cox proportional hazard model showed that PRT was an independent benefit factor in stage III rectal SRCC patients (HR, 0.611; 95% CI, 0.407–0.919; P = 0.018). In conclusion, SRCC was an independent predictor of poor prognosis in stage III RC patients, but not in stage II. In the PRT setting of locally advanced RC, SRCC patients had significantly worse prognosis. PRT was an independent prognostic factor associated with improved survival in stage III rectal SRCC.

    Sorafenib demonstrated a survival benefit in the treatment of advanced hepatocellular carcinoma (HCC) in phase III trials. However, almost all the patients included in those trials exhibited well-preserved liver function (Child-Pugh A). The aim of this study was to describe our experience with sorafenib in Child-Pugh B HCC patients. A database of patients with advanced HCC treated with sorafenib was retrospectively evaluated. The median overall survival of Child-Pugh B patients (n=20) was 2.53 months [95% confidence interval (CI): 0.33-5.92 months] and of Child-Pugh A patients (n=100) 9.71 months (95% CI: 6.22-13.04). Child-Pugh B patients had a significantly poorer survival compared to Child-Pugh A patients (P=0.002). The toxicities were similar between the two groups. Metastasis, vascular invasion and α-fetoprotein level >1,030 ng/ml were not associated with survival among Child-Pugh B patients (P=0.281, 0.189 and 0.996, respectively). Although the survival outcomes were worse in Child-Pugh B patients treated with sorafenib, the toxicity profile was manageable. Therefore, there remains the question of whether to treat this subgroup of patients and more data are required to define the role of sorafenib in the context of liver dysfunction.

    This phase II study determined response rate of patients with locally advanced or metastatic head and neck cancer treated with pemetrexed disodium, a new multitargeted antifolate that inhibits thymidylate synthase, dihydrofolate reductase and glycinamide ribonucleotide formyl transferase. 35 patients with local or metastatic relapse of squamous cell carcinoma of the head and neck (31 male, 4 female; median age 53 years) were treated with pemetrexed 500 mg m2 administered as a 10-minute infusion on day 1 of a 21-day cycle. Patients received 1 to 8 cycles of therapy. 9 patients (26.5%) had an objective response, with a median response duration of 5.6 months (range 2.9–20 months). 15 (44.1%) had stable disease, and 8 (23.5%) had progressive disease. 2 patients were not assessable for response. Median overall survival was 6.4 months (range 0.7–28.1 months; 95% CI: 3.9–7.7 months). 24 patients (68.6%) experienced grade 3/4 neutropenia, with febrile neutropenia in 4 (11.4%). Grade 3/4 anaemia and thrombocytopenia occurred in 11 (34.3%) and 6 (17.1%) patients, respectively. The most frequent non-haematological toxicity was grade 3/4 mucositis (17.1%; 6 patients). In conclusion, pemetrexed is active in squamous cell carcinoma of the head and neck. Although substantial haematological toxicities were experienced by patients, subsequent studies have shown that these toxicities can be proactively managed by folic acid and vitamin B12 supplementation. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11531245

    The authors present a series of 178 patients with Stage III or IV squamous cell carcinoma of the head and neck treated by rapid irradiation using multiple and small fractions per day. An initial group of 91 patients (G1) received a total dose of 72 Gy in 80 sessions and 10 days, according to the following split course schedule: J1 to J5, 36 Gy in 40 sessions, eight daily fractions of .9 Gy separated by 2 hours; J6 to J20, rest period; J21 to J25, same as in J1 except that the spinal cord was shielded. This protocol was altered for the following 87 patients (G2) by lessening the total dose to 60 to 66 Gy and the number of fractions to 60. The rest period was lengthened to 4 weeks. All patients but five completed the whole program and the minimal follow-up period was 24 months. At the end of irradiation, 121 patients achieved a total remission, but local recurrences occurred in 56%. Moreover, acute intolerance was considered as severe in 34% of G1 patients, and included extensive mucosal necrosis and bleeding. Although this rate was significantly reduced in G2 patients, late complications were observed in 20 of the 25 survivors, and included trismus, cervical sclerosis, and recurrent laryngeal edema. The crude survival rate is 13% at 2 years. Although this study was not randomized, this particular type of accelerated and hyperfractionated combination of irradiation did not really improve the clinical results in advanced carcinoma of the head and neck. Other schedules and probably other tumors, less extended, should be tested.

    Extraocular sebaceous carcinoma that occurs on sebaceous gland is a rare malignant cancer with unknown causes and nonspecific clinical characters, but with distinct pathology and immunohistochemical finding. In Kangnam Sacred Heart Hospital, there was a case that the result of preoperative punch biopsy was squamous cell carcinoma and malignant proliferating trichilemmal tumor, but that of postoperative permanent biopsy was sebaceous carcinoma. The type of tumor, differentiation, location, and aesthetic results are considered to get both recurrence-safe and aesthetically pleasing result. Various flaps were considered, and modified face-lift flap, forehead rotation flap, orbicularis oculi V-Y advancement flap were planned. There were no sign of recurrence of cancer or functional and aesthetical deformities 6 months after the surgery.

    Advanced hepatocelluar carcinoma (HCC) with invasion of venous systems usually indicates not only a poor prognosis but also a contraindication for transcatheter arterial chemoembolization (TACE). This study evaluated the feasibility of TACE for advanced HCC with inferior vena cava (IVC) and right atrium (RA) tumors and, also, to search for the ideal embolization particle size. Twenty-six patients who had HCC invasion into the IVC included five patients with coexistent RA tumors that were treated with TACE. The chemoembolization method was cisplatin, doxorubicin, and mitomycin C mixed with Lipiodol and Ivalon. The selection of Ivalon particles was divided into two groups based on their size: (A) >180 {mu}m, N = 9; and (B) 47-180 {mu}m, N = 17. The overall response rate was 53.8% (14/26). Based on the response to TACE, the median survival period of the entire group was 4.2 months (range, 1.5 to 76.7 months). The median survival period of the 14 responders was 13.5 months (1.5-76.7 months), and that of the 12 nonresponders, 3.3 months (2.1 to 24.3 months) (p < 0.002). Comparing the two Ivalon particle sizes, the response rate was 12.5% (1/9 patients) for group A and 76.5% for group B (13/17 patients) (p < 0.02). No serious complication was observed post-chemoembolization. In conclusion, TACE is a safe and effective treatment for advanced HCC with IVC and RA tumors, and small Ivalon particles (47-180 {mu}m) are superior to large ones (>180 {mu}m).

    Purpose We performed a single-arm phase II study of cediranib, a pan-VEGFR tyrosine kinase inhibitor, in patients with advanced hepatocellular carcinoma (HCC). Patients and Methods Patients with histologically confirmed measurable advanced HCC and adequate hematologic, hepatic, and renal functions received cediranib 30-mg orally once daily (4 weeks/cycle). The primary endpoint was progression-free survival (PFS) rate at 3 months. Other endpoints included response rates, overall survival (OS), pharmacokinetics (PK) and biomarkers for cediranib. Results Cediranib treatment resulted in an estimated 3-month-PFS rate of 77% [60%, 99%]. Median PFS was 5.3 [3.5,9.7] months, stable disease was seen in 5/17 patients (29%), and median OS was 11.7 [7.5–13.6] months. Grade 3 toxicities included hypertension (29%), hyponatremia (29%) and hyperbilirubinemia (18%). Cediranib PK were comparable to those seen in cancer patients with normal hepatic function. Plasma levels of VEGF and PlGF increased and sVEGFR1, sVEGFR2 and Ang-2 decreased after cediranib treatment. PFS was inversely correlated with baseline levels of VEGF, sVEGFR2, and bFGF and with on-treatment levels of bFGF and IGF-1, and directly associated with on-treatment levels of IFN-γ. OS was inversely correlated with baseline levels of sVEGFR1, Ang-2, TNF-α, CAIX and CD34+CD133+CD45dim circulating progenitor cells and on-treatment levels of sVEGFR2. Conclusions Despite the limitations of primary endpoint selection, cediranib at 30-mg daily showed a high incidence of toxicity and preliminary evidence of antitumor activity in advanced HCC. Hepatic dysfunction did not appear to affect the steady-state PK of cediranib. Exploratory studies suggested pro-angiogenic and inflammatory factors as potential biomarkers of anti-VEGF therapy in HCC. PMID:23362324

    Patients suffering from advanced basal cell carcinoma (BCC) have very limited treatment options. Sonidegib selectively inhibits the growth of Hedgehog pathway-dependent tumors and can treat locally advanced BCC patients who are not candidates for surgery or radiation therapy. The BOLT clinical trials were conducted to evaluate the efficacy/potency of sonidegib in the treatment of advanced BCC or metastatic BCC. The patients were randomized in 1:2 ratios to receive 200 or 800 mg oral sonidegib daily, stratified by disease, histological subtype and geographical region. The primary efficacy analyses showed that 18 patients in the 200 mg group and 35 patients in the 800 mg group show an objective response (Central Review Committee) that corresponds to 43% (95% confidence interval [CI]: 28–59) and 38% (95% CI: 28–48) in their respective categories. Disease control was found in 93% (39 patients) and 80% (74 patients) of the patients administered 200 and 800 mg sonidegib, respectively. The adverse events were assessed by the Central Review Committee as well as the investigator review team as per the guidelines of National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03. The most frequently found adverse events reported in BOLT trials were muscle spasms, alopecia, dysgeusia (taste disturbance), nausea, elevated blood creatine kinase and fatigue. Comparatively, the patients administered 200 mg sonidegib showed fewer adverse events than those in the 800 mg sonidegib category. Thus, the benefit of using the 200 mg dose of sonidegib outweighs the associated risks and it can be inferred that it would be judicious to choose doses of lesser strength. PMID:28182134

    The goal of the study was to compare the efficacy and safety of sorafenib with those of systemic cytotoxic chemotherapy. Sorafenib treatment has shown to improve the survival in patients with advanced hepatocellular carcinoma (HCC) when compared with placebo. However, whether sorafenib controls advanced-stage HCC better than systemic cytotoxic chemotherapy has not been elucidated. We retrospectively reviewed the medical records of 220 patients with measurable advanced HCC who had not received systemic treatment previously between January 2007 and April 2012. Among these patients, 78 had been treated with sorafenib. Another 14 patients who were treated with a 4-weekly regimen of adriamycin, cisplatin, and capecitabine were included as the historical control group for comparison. The median overall survival, the progression-free survival, response rates, and safety profiles were evaluated. Baseline characteristics were similar between the treatment groups. The median overall survival was 7.2 months [95% confidence interval (CI), 5.6-8.8] in the sorafenib group and 11.2 months (95% CI, 8.1-14.2) in the cytotoxic chemotherapy group (P=0.10). The median progression-free survival was 3.2 months (95% CI, 2.2-4.3) in the sorafenib group and 5.9 months (95% CI, 3.6-8.2) in the cytotoxic chemotherapy group (P=0.07). The deterioration of liver function and neutropenia were the most frequent serious adverse events in the sorafenib and the systemic chemotherapy group. Although a direct head-to-head comparison could not be done, there were some patients who showed a good response to systemic cytotoxic chemotherapy. Further assessment is necessary to study the role of chemotherapy in patients who are intolerant or intractable to sorafenib.

    Background: Pazopanib, an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptor (VEGFR)/platelet-derived growth factor receptor (PDGFR)/c-Kit, is approved in locally advanced/metastatic renal cell carcinoma (RCC). Methods: Data from trials in advanced solid tumours and advanced/metastatic RCC were used to explore the relationships between plasma pazopanib concentrations and biomarker changes, safety, and efficacy. Initially, the relationships between pharmacokinetic parameters and increased blood pressure were investigated, followed by analysis of steady-state trough concentration (Cτ) and sVEGFR2, safety, progression-free survival (PFS), response rate, and tumour shrinkage. Efficacy/safety end points were compared at Cτ decile boundaries. Results: Strong correlation between increased blood pressure and Cτ was observed (r2=0.91), whereas weak correlation was observed between Cτ and decline from baseline in sVEGFR2 (r2=0.27). Cτ threshold of >20.5 μg ml−1 was associated with improved efficacy (PFS, P<0.004; tumour shrinkage, P<0.001), but there was no appreciable benefit in absolute PFS or tumour shrinkage from Cτ >20.5 μg ml−1. However, the association of Cτ with certain adverse events, particularly hand–foot syndrome, was continuous over the entire Cτ range. Conclusions: The threshold concentration for efficacy overlaps with concentrations at which toxicity occurs, although some toxicities increase over the entire Cτ range. Monitoring Cτ may optimise systemic exposure to improve clinical benefit and decrease the risk of certain adverse events. PMID:25349968

    This study determines the short-term efficacy and toxicity of combined 125I-seed implantation and nimotuzumab in treating the advanced oral carcinoma. 125I-seed implantation is safe and has shown good short-term efficacy in clinical practice. Nimotuzumab is a useful biological agent for targeted therapy. Effect of 125I-seed implantation with nimotuzumab in treating oral carcinomas remains unclear. From November 2011 to December 2012, 11 patients with advanced oral carcinoma (pathologic types: 7 cases of squamous cell carcinoma and 4 cases of poorly differentiated adenocarcinoma) were enrolled in our hospital. The patients did not receive surgery due to systemic disease or locally advanced cancer. All of them underwent 125I-seed implantation with the matched peripheral doses (MPD) ranging from 90-100 Gy. The apparent activity per seed ranged from 0.6 mCi (2.22 MBq) to 0.7 mCi (2.59 MBq). Later, all patients were given nimotuzumab (200 mg, intravenous drip, weekly, for 6 weeks). The patients were then followed up and the response rate, acute/chronic radiation-induced injury, and safety of the induction treatment were analyzed. Three patients achieved complete while 6 patients had partial response; yielding a response rate of 81.8%. Major adverse events included radiation-induced oral mucositis, local hemorrhage, bone marrow suppression, nausea/vomiting, and alopecia. Adverse reaction was not significantly different between the group of patients under 65 years of age and over 65 years of age (p > 0.05). Nimotuzumab enhanced the tumor sensitivity to brachytherapy without increasing AEs and improved the patients' life quality. 125I-seed implantation combined with nimotuzumab is effective and safe for patients with unresectable oral carcinoma.

    Serous adenocarcinoma of the cervix (SACC) is a very rare tumor. Our study aimed to characterize the immune profile and human papillomavirus (HPV) status of SACC, in comparison with other serous adenocarcinomas arising in the female genital tract. The pathological specimens obtained from 81 patients with serous carcinoma of the uterine cervix (n = 12), 29 endometrium, 20 ovary and 20 patients with mucinous carcinoma of the uterine cervix were reviewed. We assessed the expression of WT-1, p53, p16, HER2, CEA, and CA125 by immunohistochemistry and HPV DNA by PCR in 12 SACC samples. Their immune profile was compared with that of uterine papillary serous carcinoma (UPSC), ovarian serous adenocarcinoma (OSA), and mucinous endocervical adenocarcinoma (MEA). WT-1 and HER2 were expressed in very few SACC samples (0 and 0%, respectively), but p16, CA125, CEA and p53 were present in 100, 92, 58 and 50%, respectively. The difference in WT-1 expression between SACC and UPSC, MEA is not significant, but SACC differ significantly from OSA (p < 0.01). HPV DNA (type 16 or 18) was detected in 4 of the 12 SACC. The immunophenotype of SACC was similar to UPSC, whereas the frequency of expression of WT-1 was significantly lower in SACC than OSA. It appeared that p53 expression was associated with worse clinical outcome in patients with SACC, and that HPV infection was related to its occurrence.

    Extensive recurrences on the chest wall of advanced carcinoma of the breast in 20 patients were treated with multiple field patchwork hyperthermia combined with radiation therapy between 1987-1991. The objective of the study was to evaluate the feasibility, tumour response and complications of treating extensive lesions with multiple, overlapping fields of hyperthermia. All lesions were diffuse encompassing up to 2900 cm2 in area with or without multiple nodules < or = 3 cm deep. All lesions had failed previous therapy with all but three failing previous radiotherapy. Hyperthermia consisted of 282 hyperthermia applicator fields and 357 hyperthermia treatments with external 915 MHz microwaves using commercially available applicators. Hyperthermia applicator fields were defined by the surface 50% SAR distribution of a particular applicator, and hyperthermia fields were abutted to cover the entire tumour bearing area. Radiation therapy consisted of 81 fields to a mean dose of 40 +/- 1 Gy (SE), 88% of fields received between 30 and 50 Gy. The equivalent dose was 42 +/- 1 Gy, based on the linear-quadratic model and alpha/beta = 25 (Fowler 1989). Overlapping hyperthermia fields were separated by an interval of at least three days. Up to four heat sessions per week were required to cover the entire tumour in a rotating fashion. The hyperthermia treatment time was 60 min. Hyperthermia treatments were continued for the duration of radiation therapy. Each hyperthermia applicator field was heated at least once. Patients were exposed to a mean of 14 +/- 3 hyperthermia applicator fields (range of 3-46 fields) and a mean of 18 +/- 3 hyperthermia treatments (range of 6-61) delivered over a mean of 7.5 +/- 0.9 weeks (range of 3-17 weeks). Each field was heated an average of 1.3 times. The tumour complete response rate was 95% with a recurrence rate of 5%. Nevertheless, the mean survival of patients with a complete response was only 10.8 +/- 1.7 months (range of 2-28 months

    Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Although a wide range of therapeutic options is available, the efficacy of these methods and the prognosis of patients with HCC remain very poor. This study was conducted to evaluate the efficacy and safety of viscum fraxini-2 in patients with chemotherapy-naïve, advanced hepatocellular carcinoma. 23 patients with unrespectable HCC who had received no prior systemic chemotherapy with objectively measurable tumors were enrolled on this study. The mistletoe preparation for the study is an aqueous injectable solution. It contains one milliliter of viscum fraxini in dilution stage-2 (15 mg extract of 20 mg mistletoe herb from ash tree, diluted in di-natrium-mono-hydrogen phosphate, ascorbic acid and water) which is equivalent to 10 000 ng/ml injection ampoules. 2 ampoules of viscum fraxini-2 were administered subcutaneously once weekly. As assessed by conventional imaging criteria, 3 (13.1%) patients have achieved complete response, 2 (8.1%) patients have achieved a partial response. 9 (39.1%) had progressive disease while 9 (39.1%) patients didn't have evaluation of response due to early death. The median overall survival time for all patients was 5 months (range 2-38 months), for those who achieved a CR was 29 months (range 12-38 months) and, for those who achieved a PR was 6.5 months (range 6-7 months). The median progression free survival for all patients was 2 months (range 1-38 months), for those who achieved a CR, it was 29 months (range 8-38 months) and for those who achieved a partial response, it was 5 months (range 4-6 months). No hematologic toxicity has been encountered. The spectrum of non-hematologic toxicity was mild. The WHO toxicity criteria grade 3-4 were 34.8% drug related fever, 13.1% erthyma at injection site and 17.4% pain at the site of injection. No drug related discontinuation or toxic deaths have occurred. Viscum fraxini-2 seems to be particularly promising in

    We retrospectively evaluated the effect of the surgical resection of the remaining tumor after modified M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) (m-M-VAC) treatment for locally advanced or metastatic urothelial carcinoma. In m-M-VAC therapy, methotrexate and vinblastine on 15 and 22 days were omitted from the classical M-VAC to avoid the discontinuation and the dose reduction, and duration of 1 course was shortened to 21 days from 28 days of the classical M-VAC. Seven patients with locally invasive or metastatic carcinoma of the renal pelvis, ureter, and bladder, 6 males and 1 female, with a median age 64.1 years, ranging from 49 to 77 years received m-M-VAC chemotherapy without severe side effects. In all patients, the residual viable carcinoma was completely resected and they achieved complete remission. The median survival time was 20 months (range, 7 to 61). Five of these 7 patients were still alive. Two patients had no recurrence and achieved long-term survival (survival duration; 61 and 39 months). Although further studies and long-term follow up are required, these results suggest that patients who present with locally advanced or metastatic urothelial carcinoma may benefit from surgical resection after m-M-VAC.

    Two black African women and one black American man had carcinomas of cervix, perineum, and sigmoid colon, respectively. In each of these patients, trophozoites of Entamoeba histolytica had invaded the surface of the tumor, and in some areas had invaded more deeply into the stroma between the tumor cells. Although it is well known that cutaneous amebiasis of anus, penis, vulva, and cervix can mimic squamous cell carcinoma, it may be, perhaps, less well known that carcinomas at these sites may be colonized by trophozoites of E. histolytica. In patients with amebiasis but without an associated carcinoma, a correct diagnosis of amebiasis spares the patient unnecessary and sometimes mutilating surgery. But a diagnosis of amebiasis, when there is an unrecognized underlying carcinoma, delays effective treatment of the carcinoma. A smear that establishes a diagnosis of cutaneous amebiasis, therefore, should be followed by biopsy to exclude or confirm an underlying carcinoma.

    Immune checkpoints are emerging treatment targets, but mechanisms underlying checkpoint expression are poorly understood. Since alterations in DNA repair genes have been connected to the efficacy of checkpoint inhibitors, we investigated associations between methylation of DNA repair genes and CTLA4 and CD274 (PD-L1) expression. A list of DNA repair genes (179 genes) was selected from the literature, methylation status and expression of inflammation-associated genes (The Cancer Genome Atlas data) was correlated in head and neck squamous cell carcinoma (HNSCC), cervical and lung squamous cell carcinoma. A significant positive correlation of the methylation status of 15, 3 and 2 genes with checkpoint expression was identified, respectively. RAD51B methylation was identified in all cancer subtypes. In HNSCC and cervical cancer, there was significant enrichment for homologous recombination genes. Methylation of the candidate genes was also associated with expression of other checkpoints, ligands, MHC- and T-cell associated genes as well as an interferon-inflammatory immune gene signature, predictive for the efficacy of PD-1 inhibition in HNSCC. Homologous recombination deficiency might therefore be mediated by DNA repair gene hypermethylation and linked to an immune-evasive phenotype in SCC. The methylation status of these genes could represent a new predictive biomarker for immune checkpoint inhibition. PMID:27683114

    Radiation pneumonia is a main side-effect that has limited the clinical usage of radiotherapy in locally advanced esophageal carcinoma. T helper cells 17 (Th 17) and T regulatory cells (Tregs) play an important role in inflammatory diseases. The balance between Treg and Th17 cells is a key factor in the progression of many inflammatory and autoimmune diseases. Whether Tregs and Th17 cells are predictive factors of radiation pneumonia has not yet been reported. In this study, we investigated the relationships of Treg/Th17 cells and radiation pneumonia in patients with locally advanced esophageal cancer who received radiotherapy. One hundred and forty-eight patients with locally advanced esophageal cancer who received radical and palliative radiotherapy were enrolled. The levels of Th17 and Treg cells in the blood of patients were detected using flow cytometry at the time point of pre-radiotherapy, 1st, 2nd, 3rd, 4th, 5th and 6th week from the start of radiation and 4 weeks after completion of radiotherapy. Radiation pneumonia was evaluated according to Radiation Therapy Oncology Group's acute radiation pneumonia standards, with the endpoint being grade 2 or above radiation pneumonia. There were 24 cases of radiation pneumonia in 148 cases of locally advanced esophageal cancer patients who underwent radiotherapy. Th17 cells increased and, in contrast, Treg cells decreased in the radiation pneumonia group. The change in the ratio of Th17/Treg was more pronounced and the difference was statistically significant from the 5th week after irradiation compared to patients with no radiation pneumonia (p<0.05). There was no significant difference in dosimetric parameters, including V5, V20, V30 and mean lung dose (MLD) and clinical factors, such as gender, age, smoking history, history of surgery and chemotherapy. The ratio of Th17/Treg cells may be an effective predictive factor of radiation pneumonia. Copyright© 2017, International Institute of Anticancer Research (Dr

    Background N-stage is related to distant metastasis in nasopharyngeal carcinoma (NPC) patients. The purpose of this study was to evaluate the efficacy and toxicity of different nedaplatin-based chemotherapy regimens in advanced N2-3 stage NPC patients treated with intensity modulated radiation therapy (IMRT). Patients and Methods Between April 2005 and December 2009, a total of 128 patients with N2-3 advanced NPC were retrospectively analyzed. Patients were treated with IMRT concurrent with 2 cycles of chemotherapy consisting of either nedaplatin plus paclitaxel (NP group, n = 67) or nedaplatin plus fluorouracil and paclitaxel (NFP group, n = 61). Two to four cycles of adjuvant chemotherapy were then administered every 21 days following concurrent chemoradiotherapy. Results With a median follow-up of 60 months, the 5-year overall survival (OS), progression-free survival (PFS), local-regional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) for all patients were 81.4%, 71.5%, 87.8% and 82.0%, respectively. No significant difference in PFS (66.6% vs. 76.7%, P = 0.212) and LRRFS rates (89.0% vs. 86.3%, P = 0.664) was observed between the NP and NFP groups. The 5-year OS (75.4% vs. 88.5%, P = 0.046) and DMFS (75.1% vs. 89.0%, P = 0.042) rate were superior in the NFP group compared with the NP group. The NFP group had a higher incidence of grade 3–4 acute toxicities including bone marrow suppression (leukopenia: χ2 = 3.935, P = 0.047; anemia: χ2 = 9.760, P = 0.002; thrombocytopenia: χ2 = 8.821, P = 0.003), and both liver and renal dysfunction (χ2 = 5.206, P = 0.023) compared with the NP group. Late toxicities were moderate and no difference was observed between the two groups. Conclusion IMRT concurrent with nedaplatin-based chemotherapy is an advocated regimen for patients with advanced N2-3 stage NPC. Patients with advanced N2-3 stage may be better candidates for the NFP regimen although this regimen was associated with a high acute

    Background Although both the SHARP and the Asian-Pacific trials showed improved overall survival (OS) for sorafenib, the magnitude of benefit was substantially less for Asians, who have a higher prevalence of hepatitis B viral (HBV) infection. Whether the worse prognosis is related to ethnicity or to the etiology of hepatocellular carcinoma (HCC) remains unclear. The aim of this study was to identify prognostic factors among patients with HCC who received sorafenib in British Columbia (BC), which has a sizeable Asian population. Methods A total of 255 consecutive patients with advanced HCC who initiated sorafenib from January 2008 to February 2013 were identified using our pharmacy database. Clinicopathological variables and outcomes were retrospectively collected. Prognostic factors were assessed by univariate and multivariate analyses. Results Median age was 63 years, 80.2% were men, and 38% were Asian. Among them, 34.5% had HBV and 29.8% had hepatitis C viral (HCV) infection. In addition, 68.6% had cirrhosis and 45.9% had liver-limited disease. Median progression-free and OS were 3.7 [95% confidence interval (CI): 3.3-4.2] and 7.5 months (95% CI: 5.7-9.2), respectively. On multivariate analysis, Eastern Cooperative Oncology Group performance status (ECOG PS) and HCV positivity correlated with better OS (P<0.001 and 0.04, respectively), but ethnicity did not (P=0.622). Conclusions When treated with sorafenib at the same institution, Asians and Caucasians with advanced HCC had similar OS. ECOG PS and HCV were the only significant prognostic factors. A higher proportion of HCV positivity might explain why the SHARP trial achieved better OS when compared to the Asian-Pacific trial. PMID:25083298

    Atelectasis was reported as a favorable prognostic sign of pulmonary carcinoma; however, the underlying mechanism in those patients is not known. In this study, we aimed to investigate prospectively the potential impact of atelectasis and/or obstructive pneumonitis (AO) on survival and the relation between atelectasis and some laboratory blood parameters. The study was conducted on 87 advanced stage non-small cell lung cancer (NSCLC) patients. Clinical and laboratory parameters of patients at first presentation were recorded, and patients were divided into two groups according to the presence of AO in thorax computed tomography (CT). Survival was calculated using Kaplan-Meier and univariate Cox's regression analyses. Laboratory parameters that might be related with prolonged survival in atelectasis were compared using chi-square, Student's t, and Mann-Whitney U tests. Of the patients, 54% had stage IV disease, and AO was detected in 48.3% of all cases. Overall median survival was 13.2 months for all cases, 10.9 months for patients without AO, and 13.9 months for patients with AO (P = 0.067). Survival was significantly longer in stage III patients with AO (14.5 months versus 9.2 months, P = 0.032), but not in stage IV patients. Patients with AO in stage III had significantly lower platelet counts (P = 0.032) and blood sedimentation rates than did those with no AO (P = 0.045). We concluded that atelectasis and/or obstructive pneumonitis was associated with prolonged survival in locally advanced NSCLC. There was also a clear association between atelectasis and/or obstructive pneumonitis and platelets and blood sedimentation rate. PMID:20636252

    Purpose: The prognosis of hepatocellular carcinoma (HCC) patients with extrahepatic metastases is extremely poor. Helical tomotherapy, an image-guided, intensity-modulated radiotherapy system, can allow for simultaneous and precise targeting of multiple cancerous lesions, while sparing normal tissues. This study evaluated the feasibility and outcome of tomotherapy for advanced HCC with metastases. Patients and Methods: A total of 42 consecutive HCC patients with metastases were treated with tomotherapy using the Hi-Art system. A total of 152 intra- and extrahepatic lesions (3.5 lesions/patient) were treated simultaneously, with a dose of 51.03 Gy (range, 30-57.61) in 10 fractions. Transarterial chemolipiodolization using epirubicin (50 mg) and cisplatin (60 mg) was repeated in patients with intrahepatic HCC (mean size, 9.0 cm) after tomotherapy. Results: An objective response (complete response and partial response) was achieved in 45.2% of patients with intrahepatic tumors, 68.4% of patients with pulmonary lesions, 60.0% of patients with lymph node/adrenal lesions, and 66.7% of patients with soft-tissue metastases. The complete response rate for those with pulmonary and lymph node/adrenal metastases was 26.3% and 5.0%, respectively. The overall survival rate at 1 and 2 years was 50.1% and 14.9%, respectively, with a median survival of 12.3 months. The actuarial in-field tumor control rate for {<=}1 year was 79.0%. No cases of Grade 4-5 acute toxicity occurred. Conclusion: The results of this study have shown that helical tomotherapy is safe and feasible without major toxicities for the treatment of advanced HCC and results in excellent tumor control and a potential survival benefit. This approach is expected to be a useful palliative option for selected HCC patients with metastases.

    Purpose: The aim of this study was to investigate prognostic factors in advanced-stage oral tongue cancer treated with postoperative adjuvant therapy and to identify indications for adjuvant concomitant chemoradiotherapy (CCRT). Methods and Materials: We retrospectively reviewed the records of 201 patients with advanced squamous cell carcinoma of the oral tongue managed between January 1995 and November 2002. All had undergone wide excision and neck dissection plus adjuvant radiotherapy or CCRT. Based on postoperative staging, 123 (61.2%) patients had Stage IV and 78 (38.8%) had Stage III disease. All patients were followed for at least 18 months after completion of radiotherapy or until death. The median follow-up was 40.4 months for surviving patients. The median dose of radiotherapy was 64.8 Gy (range, 58.8-72.8 Gy). Cisplatin-based regimens were used for chemotherapy. Results: The 3-year overall survival (OS) and recurrence-free survival (RFS) rates were 48% and 50.8%, respectively. Stage, multiple nodal metastases, differentiation, and extracapsular spread (ECS) significantly affected disease-specific survival on univariate analysis. On multivariate analysis, multiple nodal metastases, differentiation, ECS, and CCRT were independent prognostic factors. If ECS was present, only CCRT significantly improved survival (3-year RFS with ECS and with CCRT = 48.2% vs. without CCRT = 15%, p = 0.038). In the presence of other poor prognostic factors, results of the two treatment strategies did not significantly differ. Conclusions: Based on this study, ECS appears to be an absolute indication for adjuvant CCRT. CCRT can not be shown to be statistically better than radiotherapy alone in this retrospective series when ECS is not present.

    Intensity-modulated radiation therapy (IMRT) is gaining acceptance as a standard treatment technique for advanced squamous cell carcinoma (SCC) of the oropharynx. Dose to the uninvolved larynx and surrounding structures can pose a problem in patients with significant neck disease, potentially compromising laryngeal function and quality of life. Tomotherapy may allow greater laryngeal sparing. Seven patients with stage IV SCC of the oropharynx were replanned using Tomotherapy version 3.1. All contours/planning target volumes (PTVs) from the original plans were preserved, with the exception of the larynx, which was drawn to include all soft tissue encompassed by the thyroid/cricoid cartilage. A simultaneous integrated boost technique was used with PTV 1, 2, and 3 receiving 69.96, 59.40, and 54.00 Gy, respectively in 33 fractions. Dosimetry was evaluated via the Pinnacle treatment planning system (TPS). Equivalent uniform dose (EUD) was calculated from the dose volume histogram (DVH) using the general method with "a" = 5.0. Mean larynx dose for all patients was 24.4 Gy. Mean EUD to the larynx was 34.2 Gy. Homogeneity was adequate; average maximum dose was 109.7% of the highest prescription. All other organs at risk (OAR) were adequately spared. Tomotherapy can spare the uninvolved larynx in the setting of advanced SCC of the oropharynx to levels that are similar to or better than those reported with other techniques. Sparing is achieved without compromising target coverage or other OAR sparing. The clinical benefit of this sparing remains to be determined in a prospective study.

    Advanced stage hepatocellular carcinoma (HCC) is a category of disease defined by radiological, clinical and hepatic function parameters, comprehending a wide range of patients with different general conditions. The main therapeutic option is represented by sorafenib treatment, a multi-kinase inhibitor with anti-proliferative and anti-angiogenic effect. Trans-arterial Radio Embolization also represents a promising new approach to intermediate/advanced HCC. Post-marketing clinical studies showed that only a portion of patients actually benefits from sorafenib treatment, and an even smaller percentage of patients treated shows partial/complete response on follow-up examinations, up against relevant costs and an incidence of drug related adverse effects. Although the treatment with sorafenib has shown a significant increase in mean overall survival in different studies, only a part of patients actually shows real benefits, while the incidence of drug related significant adverse effects and the economic costs are relatively high. Moreover, only a small percentage of patients also shows a response in terms of lesion dimensions reduction. Being able to properly differentiate patients who are responding to the therapy from non-responders as early as possible is then still difficult and could be a pivotal challenge for the future; in fact it could spare several patients a therapy often difficult to bear, directing them to other second line treatments (many of which are at the moment still under investigation). For this reason, some supplemental criteria to be added to the standard modified Response Evaluation Criteria in Solid Tumors evaluation are being searched for. In particular, finding some parameters (cellular density, perfusion grade and enhancement rate) able to predict the sensitivity of the lesions to anti-angiogenic agents could help in stratifying patients in terms of treatment responsiveness before the beginning of the therapy itself, or in the first weeks of

    Background Although sorafenib is considered standard therapy for advanced hepatocellular carcinoma (HCC), actual treatments vary. We evaluated the effects of different treatment strategies on overall survival. Methods A retrospective study of sorafenib-treated patients with advanced HCC was conducted. The primary outcome was overall survival. Prognostic factors were analyzed using multivariate Cox-proportional hazards model. Results A total of 658 patients (mean age, 54.5 years; 83.3% male) were analyzed; 293, 129, and 236 patients were treated with sorafenib, a combination therapy of sorafenib and transarterial chemoembolization (TACE), and TACE followed by sorafenib, respectively. Overall, 51.2% of patients treated under the combination strategy had portal vein invasion, whereas 89.9% of patients receiving sorafenib monotherapy had distant metastasis. Median overall survival durations were comparable (11.8 months for sorafenib, 16.2 months for the combination therapy, and 13.5 months for TACE followed by sorafenib; P = 0.13). However, among portal vein invasion cases, combination (25.7 months, P = 0.002) and TACE followed by sorafenib (14.0 months, P = 0.030) treatments were associated with longer overall survival duration compared with than sorafenib monotherapy (5.5 months). In a multivariate model, sorafenib duration (hazard ratio [HR], 0.96, P < 0.001) and TACE (HR, 0.24, P < 0.001) along with Child-Pugh stage (HR, 1.83, P = 0.005) were associated with better survival. Conclusions In patients with portal vein invasion, TACE performed concurrently with or before sorafenib administration is associated with better survival. PMID:27494871

    Purpose. Vismodegib was approved for the treatment of advanced basal cell carcinoma (aBCC) based on the pivotal ERIVANCE BCC study. The primary endpoint (objective response rate [ORR]) was assessed 9 months after the last patient was enrolled. To confirm the clinical benefit of vismodegib, an additional analysis was performed 12 months after the primary analysis. Materials and Methods. ERIVANCE BCC was a multicenter, nonrandomized, two-cohort study of 104 patients with histologically confirmed aBCC. Patients received 150 mg oral vismodegib daily until disease progression, intolerable toxicity, or withdrawal. An independent review panel comprising three expert clinicians reviewed patient photographs individually and as a consensus panel to evaluate baseline disease severity and clinical benefit after vismodegib treatment in 71 patients with locally advanced BCC (laBCC). Results. Sixty-three patients were efficacy evaluable; baseline and postprogression photographs for 61 were available for review. Baseline disease severity was judged as 5 or 4 (very severe or moderately severe) in 71.4%. Clinical benefit was observed in 76.2% (significant: 65.1%; some: 11.1%). Interpanelist agreement (maximum difference ≤1 point among panelists’ scores in 65.1% and 87.3% of patients for clinical benefit and baseline disease severity, respectively) and correlation between individual and panel reviews were strong. Clinical benefit scores showed good concordance with the protocol-specified ORR obtained by an independent review facility and with investigator-assessed response. Conclusion. Clinical benefit assessed by independent review based on expert clinical judgment provides strong evidence that treatment with vismodegib results in clinically meaningful and durable responses in patients with laBCC.

    The aim of this study was to characterize the clinical and molecular markers of borderline serous ovarian tumors (BSOT), and to study their expression in the progression from benign lesions to advanced serous papillary ovarian carcinomas (SPOC). The clinical records of 20 patients with BSOT and 22 patients with SPOC were reviewed. Specimens from all these cases and from six benign ovarian serous cystadenomas were evaluated for expression of estrogen receptors (ER), progesterone receptors (PR), p53. HER-2/neu and Ki-67 by immunohistochemical techniques. The mean patient age and the age at menarche differed significantly between the compared groups of BSOT and SPOC (p=0.0006 and p=0.0014, respectively). No difference was observed comparing the other clinical parameters. The immunohistochemical analysis demonstrated a significant increase in the expression of ER (100% vs 72.7%), and a significant decrease in the immunoreactivity for p53 (0% vs 45.4%) and Ki-67 (2% vs 26.8%) in cases of BSOT compared with those of SPOC (p=0.007, p=0.0003 and p=0.012, respectively). No significant difference was demonstrated comparing the expression of PR and HER-2/neu. The immunostaining of benign ovarian serous cystadenoma specimens did not differ significantly from immunoreactivity observed in cases of BSOT. According to immunohistochemical analysis, BSOT had much more in common with benign serous tumors than with SPOC. The main difference between BSOT and SPOC was regarding the overexpression of p53 and Ki-67.

    Oral squamous cell carcinoma (OSCC) is a common cause of cancer death. Despite decades of improvements in exploring new treatments and considerable advance in multimodality treatment, satisfactory curative rates have not yet been reached. The difficulty of early diagnosis and the high prevalence of metastasis associated with OSCC contribute to its dismal prognosis. In the last few decades the emerging data from both tumor biology and clinical trials led to growing interest in the research for predictive biomarkers. Non-coding RNAs (ncRNAs) are promising biomarkers. Among numerous kinds of ncRNAs, short ncRNAs, such as microRNAs (miRNAs), have been extensively investigated with regard to their biogenesis, function, and importance in carcinogenesis. In contrast to miRNAs, long non-coding RNAs (lncRNAs) are much less known concerning their functions in human cancers especially in OSCC. The present review highlighted the roles of miRNAs and newly discovered lncRNAs in oral tumorigenesis, metastasis, and their clinical implication.

    Background In patients with unresectable cholangiocarcinoma, photodynamic therapy (PDT) with porfimer sodium promotes biliary drainage and may improve survival and quality of life. Aim To prospectively evaluate the safety and efficacy of PDT in patients with locally advanced biliary tract carcinoma. Methods Eligible patients had unresectable, histologically confirmed disease, a Karnofsky performance status of ≥30% and life expectancy >12 weeks. Patients received 2mg/kg i.v. of porfimer sodium, followed by endobiliary laser activation and stent replacement 48 hrs later. Patients were assessed clinically and radiologically before treatment and on day 28, and followed up thereafter at three-monthly intervals until death. Results 36 patients were entered over an 18 months period: 14 males, 22 females, with a median age of 65 (30-79) yr and performance status of 80 (50-100). PDT was technically successful in all cases and was generally well tolerated; there was no grade 4 toxicity and no treatment-associated mortality. The median survival was 12 (1-84) months. Conclusions Porfimer sodium PDT can be delivered safely to patients with biliary tract cancer and is suitable for testing in phase III studies (UKCRN ID 1218). PMID:23200007

    Background The role of induction chemotherapy is less clear in non-endemic locally advanced nanopharyngeal carcinomas (NPC). Results With a total of 233 eligible patients and a median follow-up of 36 months, 3-year overall survival (OS), local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), disease free survival (DFS) were 84.5%, 94.9%, 78.6% and 69.2%, respectively. The overall failure rate was 21.0% and distant metastasis occurred in 17.2% patients. Multivariate analyses showed that retropharyngeal and bilateral neck lymph node metastasis were significant prognostic factors for DFS and OS. Moreover, patients receiving both GP (gemcitabine+cisplatin) and TP (docetaxel+cisplatin) regimes had significantly higher DFS and OS compared with PF (cisplatin+5-FU) regime. GP regimes lead to significantly improved OS than TP/PF in some subgroup of patients. No severe toxicities were observed. Materials and Methods We retrospectively analyzed stage III-IVb NPC patients treated between Jan 2006 and Dec 2014, with induction chemotherapy followed by concurrent chemoradiation (IC-CCRT). Statistical analyses were performed on survival and failure patterns. Conclusions These results suggested IC-CCRT was safe and effective for NPCs from non-endemic region. The choice of induction regimen appeared to affect patient outcomes. PMID:28036270

    Hepatocellular Carcinoma (HCC) is a major healthcare problem. Almost ninety percent of HCCs develops on cirrhosis due to chronic viral hepatitis, Non-Alcoholic Steatohepatitis (NASH) and alcohol abuse. Alcohol itself is defined a strong human carcinogenic agent. Some genetic polymorphisms in alcohol-metabolizing systems and more recently, some sequence variations within the genes coding for patatin-like phospholipase encoding 3 (PNPLA3) and Transmembrane 6 superfamily 2 (TM6SF2), have been found to promote liver fibrosis in alcohol abuse, until HCC development. The current management of HCC is related to tumor burden and liver function and it does not differ in alcoholics, although in alcoholics the surveillance for HCC could be less effective because socioeconomic context, such as the recall policy, the stage at the diagnosis and the prognosis are not different compared to viral HCCs. On regards of loco-regional treatment options, there have not been significant advances in the last few years, though an increasing role will be probably reserved to radio embolization and irreversible electroporation in the next future. Sorafenib (SOR) is still the only drug approved as systemic therapy in patients with HCC, whereas immunotherapy represents a promising approach for the treatment of HCC.

    The Hedgehog (Hh) pathway is critical for cell differentiation, tissue polarity, and stem cell maintenance during embryonic development, but is silent in adult tissues under normal conditions. However, aberrant Hh signaling activation has been implicated in the development and promotion of certain types of cancer, including basal cell carcinoma (BCC), medulloblastoma, and gastrointestinal cancers. In 2015, the US Food and Drug Administration (FDA) approved sonidegib, a smoothened (SMO) antagonist, for treatment of advanced BCC (aBCC) after a successful Phase II clinical trial. Sonidegib, also named Odomzo, is the second Hh signaling inhibitor approved by the FDA to treat BCCs following approval of the first SMO antagonist vismodegib in 2012. What are the major features of sonidegib (mechanism of action; metabolic profiles, clinical efficacy, safety, and tolerability profiles)? Will the sonidegib experience help other clinical trials using Hh signaling inhibitors in the future? In this review, we will summarize current understanding of BCCs and Hh signaling. We will focus on sonidegib and its use in the clinic, and we will discuss ways to improve its clinical application in cancer therapeutics. PMID:28352196

    To analyze the nutritional status and nosocomial infection of nasopharyngeal carcinoma patients before and after the chemoradiotherapy treatment. An analysis was made for the nutritional and nosocomial infection status of 82 cases before and after chemoradiotherapy treatment. Statistically significant differences were revealed between indexes related with nutritional status such as body mass, hemoglobin, serum albumin before and after the treatment. Sixty-three patients occurred nosocomial infection. The infection rate was 76.83%. The main risk factor was oropharynx mucosal lesion and the rate is 92.68%. Isolates of 39 bacteria were found, of which Gram-negative organisms were 58.97%, Fungi were 30.77%, Gram-positive ones were 7.69%, Herpes zoster were 2.56%. Chemoradiotherapy has negative influence on nutritional status of patients. Medical personnel should pay attention to patients' nutritional status and do a good job of nutritional status monitoring, nutrition support, dieting guidance, reducing side effects, in order to improve the patient's tolerability and quality of life. The nosocomial infection rate of Gram-negative bacteria of oropharyngeal mucosal is the highest in patients with advanced nasopharyngeal cancer during chemoradiotherapy. It is very important for us to prevent and control nosocomial infection.

    Chronic liver diseases alone or in conjunction with other risk factors result in increased liver damage leading to inflammation and fibrosis of the liver and rising rates of liver cirrhosis, hepatic decompensation and hepatocellular carcinoma (HCC). This review will address the determinants of liver injury at the initiation of the tumor and the risk factors for rapid disease progression. Regardless of the etiology, the unifying feature of these tumors are their propensity to arise upon a background of inflammation and fibrosis. Liver disease is often associated with enhanced hepatocyte apoptosis, which is the case in viral and autoimmune hepatitis, cholestatic diseases, and metabolic disorders. Disruption of apoptosis is responsible for HCC. The mechanisms by which apoptosis occurs in the liver might provide insights into HCC and suggest possible treatments. We aim to better understand the factors that distinguish a relatively long course of HCC from one with rapid progression. We will accomplish this task with three integrated ideas: 1 - the role of epidemiology in establishing the risk factors of co-morbidity with alcohol and hepatitis viruses; 2 - the role of apoptosis and anti-apoptotic signals in the progression of HCC; and 3 - the role of new advancements that have emerged in the field of molecular-directed chemotherapeutics in HCC in recent years. This review will also aim to describe the molecular targeted therapies of non-resectable HCC and the ways of effective combination in this otherwise chemo-resistant tumor.

  14. Pazopanib: a multikinase inhibitor with activity in advanced renal cell carcinoma.

    2010-05-01

    Treatment options for patients with metastatic renal cell carcinoma (RCC) have changed dramatically, and a new paradigm has evolved. IFN-alpha and IL-2 were previously mainstays of therapy, but since December 2005, six new agents have been approved in the USA for the treatment of advanced RCC. Three of these new agents are multitargeted kinase inhibitors, including sunitinib, sorafenib, and recently pazopanib, two target the mTOR (temsirolimus and everolimus), and one is a humanized monoclonal antibody (bevacizumab in combination with IFN-alpha) that targets VEGF. Sunitinib has emerged as the standard of care for treatment-naive RCC patients, with the recently approved bevacizumab and IFN-alpha combination providing an additional option for this population. The recent approval of pazopanib, based on the results from sequential Phase II and III clinical trials demonstrating improved overall response rates and progression-free survival, provides yet another option for front-line therapy. The current article examines the pazopanib preclinical and clinical data, provides an overview of the development of this tyrosine kinase inhibitor, and provides some speculation concerning its role in RCC therapy.

    Hepatocellular carcinoma (HCC) is one of the major causes of morbidity and mortality in patients with chronic liver disease. Transarterial chemoembolization (TACE) can significantly improve the survival rate of patients with HCC and is the first treatment choice for patients who are not suitable for surgical resections. The evaluation of the response to TACE treatment affects not only the assessment of the therapy efficacy but also the development of the next step in the treatment plan. The use of imaging to examine changes in tumor volume to assess the response of solid tumors to treatment has been controversial. In recent years, the emergence of new imaging technology has made it possible to observe the response of tumors to treatment prior to any morphological changes. In this article, the advances in studies reporting the use of computed tomography perfusion imaging, diffusion-weighted magnetic resonance imaging (MRI), intravoxel incoherent motion, diffusion kurtosis imaging, magnetic resonance spectroscopy, magnetic resonance perfusion-weighted imaging, blood oxygen level-dependent MRI, positron emission tomography (PET)/computed tomography and PET/MRI to assess the TACE treatment response are reviewed.

    Purpose: To study the safety and efficacy of dose escalation in tumor for locally advanced nasopharyngeal carcinoma (NPC). Methods and Materials: From September 2000 to June 2004, 50 patients with T3-T4 NPC were treated with intensity-modulated radiotherapy (IMRT). Fourteen patients had Stage III and 36 patients had Stage IVA-IVB disease. The prescribed dose was 76 Gy to gross tumor volume (GTV), 70 Gy to planning target volume (PTV), and 72 Gy to enlarged neck nodes (GTVn). All doses were given in 35 fractions over 7 weeks. Thirty-four patients also had concurrent cisplatin and induction or adjuvant PF (cisplatin and 5-fluorouracil). Results: The average mean dose achieved in GTV, GTVn, and PTV were 79.5 Gy, 75.3 Gy, and 74.6 Gy, respectively. The median follow-up was 25 months, with 4 recurrences: 2 locoregional and 2 distant failures. All patients with recurrence had IMRT alone without chemotherapy. The 2-year locoregional control rate, distant metastases-free and disease-free survivals were 95.7%, 94.2%, and 93.1%, respectively. One treatment-related death caused by adjuvant chemotherapy occurred. The 2-year overall survival was 92.1%. Conclusions: Dose escalation to 76 Gy in tumor is feasible with T3-T4 NPC and can be combined with chemotherapy. Initial results showed good local control and survival.

    Basal cell carcinoma (BCC) is the most common cancer in the world. It is typically slow growing and usually effectively managed with surgery. However, BCCs in some patients are unsuitable for surgery or the patient may prefer a nonsurgical treatment. Radiotherapy is a nonsurgical option for the primary treatment of either low- or high-risk BCCs. It is associated with high cure rates, albeit somewhat lower than those observed with Mohs micrographic surgery for high-risk BCCs. Not all patients with BCCs are suitable for radiotherapy. Superficial therapies for BCC include topical imiquimod or 5- fluorouracil and photodynamic therapy (PDT). These therapies are generally associated with somewhat lower clearance rates and/or higher recurrence rates than surgery or radiotherapy, although they may be suitable in patients with low-risk BCCs when surgery or radiotherapy are impractical or less appropriate. An appealing feature of PDT is excellent cosmesis, but PDT is not currently approved by the Food and Drug Administration (FDA), and regimens are not well standardized. Vismodegib is a first-in-class hedgehog pathway inhibitor and recent addition to the armamentarium for the treatment of advanced BCC.

    Metastatic lesions of renal cell carcinoma (RCC) occasionally regress spontaneously after surgical removal of the primary tumor. Although this is an exceptionally rare occurrence, RCC has thus been postulated to be immunogenic. Immunotherapies, including cytokine therapy, peptide-based vaccines, and immune checkpoint inhibitors have therefore been used to treat patients with advanced, metastatic RCC. We review the history, trends, and recent progress in immunotherapy for advanced RCC and discuss future perspectives, with consideration of our experimental work on galectin 9 and PINCH as promising specific immunotherapy targets.

    This study evaluated the survival outcome, pattern of failure and prognostic factors in cervix uteri cancer patients. We reviewed the data of 60 patients with stages IB-IVA cancer who were treated between January 2004 and December 2010. Most patients (n = 50; 83%) had squamous cell carcinoma. Stage IIB was the most common presentation (n = 41; 68%). Forty-seven patients (78%) received Cisplatin concurrent with radiotherapy (CRT). The 2- and 4-year overall survival (OS) was 82% and 79%, respectively. Prolongation of the overall treatment time (OAT) for greater than 56 days, advanced stage and pretreatment hemoglobin (Hb) levels (<10 g/dL) negatively predicted OS (P = 0.039, P = 0.044 and P = 0.008, respectively). The 2- and 4-year disease-free survival (DFS) rates were 80% and 69%, respectively. Vaginal infiltration and brachytherapy (orthogonal versus CT-based planning) were significant factors for the prediction of relapse (P = 0.048 and P = 0.049, respectively). The 2- and 4-year loco-regional control (LRC) rates were 78% and 70%, respectively, and the distant metastasis-free survival (DMFS) rates were 82% and 79%, respectively. Vaginal infiltration was the only negative predictive factor for LRC (P = 0.045), and pathological tumor grade was the only factor indicative of distant metastases (P = 0.037). Grade 3 or 4 late rectal reactions were reported in two patients (3%), and no patients developed grade 3 or 4 urinary reactions. The treatment results in our cervix uteri cancer patients and the prognostic factors are comparable to those of previous reports. Orthogonal brachytherapy planning and vaginal infiltration negatively predicted relapse. © 2016 John Wiley & Sons Australia, Ltd.

    Human papillomavirus (HPV) 16 and 18 are the types most commonly found in cervical adenosquamous carcinoma. Multiple HPV types have been found in cervical adenocarcinoma but not in the adenosquamous variant. Type-specific detection of high-risk (HR) HPV allows the detection of co-infection by multiple HPV types and assessment of viral load per cell. Our aim was to identify and quantify all HR HPV types in cervical adenosquamous carcinoma and to correlate viral loads with prognosis-related histologic features. All 15 HR HPV types were tested for by multiplex real-time polymerase chain reaction, and standard curves were created for each type. Viral loads were determined retrospectively. Prognosis-related histologic features were correlated with specific HPV types and the viral loads. A total of 80% of the tumors examined expressed HPV. Types 16/18 were detected in 86% of these cases, whereas the remaining 14% of the positive cases were infected by other types. A single type of virus was detected in 67% of cases, 2 in 29%, and 3 in 4%. Poor prognostic features were seen in 84.6% of the tumors infected with HPV 16, 46% of those infected with HPV 18, and 100% of those infected with other types. As expected, HPV 16, HPV 18, or both were the most frequent viral types; HPV 73 was the next most frequent type. Multiple HPV types were detected in 33% of the tumors. Non-HPV 16/18 cases had low viral loads, but all of these had poor prognosis-related histologic features. Two of the three recurrent cases had multiple viral types. © 2014 Elsevier Inc.

    Purpose: To look for possible associations between measurements of DNA index (DI), S-phase fraction (SPF), and tumor heterogeneity (TH) using flow cytometry and overall survival for patients with invasive cervical carcinoma treated with definitive irradiation. Methods and Materials: A total of 57 patients with International Federation of Obstetrics and Gynecology Stages IB{sub 2} through IVB cervical carcinomas treated with definitive radiotherapy with or without concurrent chemotherapy were enrolled into this registry study that involved flow cytometric analysis of fresh tissue from each cervical cancer obtained by pretreatment biopsy. These specimens were evaluated for DNA aneuploidy (DI {<=}1.5 vs. >1.5), SPF ({<=}15% vs. >15%), and TH (uniploid vs. multiploid). Results: In these analyses 27 of the patients were treated in Radiation Therapy Oncology Group protocol 9001, and an additional 30 were offered chemoradiation at a single institution. Forty-one patients had DI {<=}1.5 and 16 DI >1.5. Twenty-nine patients had SPF {<=}15%, 26 >15%, and 2 had no determinable SPF. Forty-three patients had uniploid and 14 multiploid tumors. The 4-year estimated overall survival rate for the entire study cohort was 62% (95% confidence interval 48%-74%). With a median follow-up of 3.7 years, there were no observable associations by univariate analysis for DI, SPF, or TH concerning patient survival. Conclusions: There were no statistically significant associations among DI, SPF, or TH and patient outcome. Additional studies are indicated to identify tumor biomarkers that could predict patients at risk for disseminated disease.

    Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL) involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient's case file. We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term. PMID:27597906

    Abstract Lessons Learned. Trebananib leveraging anti‐angiogenic mechanism that is distinct from the classic sorafenib anti‐vascular endothelial growth factor inhibition did not demonstrate improved progression‐free survival at 4 months in patients with advanced hepatocellular carcinoma (HCC).In support of previously reported high Ang‐2 levels’ association with poor outcome in HCC for patients, trebananib treatment with lower baseline Ang‐2 at study entry was associated with improved overall survival to 22 months and may suggest future studies to be performed within the context of low baseline Ang‐2. Background. Ang‐1 and Ang‐2 are angiopoietins thought to promote neovascularization via activation of the Tie‐2 angiopoietin receptor. Trebananib sequesters Ang‐1 and Ang‐2, preventing interaction with the Tie‐2 receptor. Trebananib plus sorafenib combination has acceptable toxicity. Elevated Ang‐2 levels are associated with poor prognosis in hepatocellular carcinoma (HCC). Methods. Patients with HCC, Eastern Cooperative Oncology Group ≤2, and Childs‐Pugh A received IV trebananib at 10 mg/kg or 15 mg/kg weekly plus sorafenib 400 mg orally twice daily. The study was planned for ≥78% progression‐free survival (PFS) rate at 4 months relative to 62% for sorafenib historical control (power = 80% α = 0.20). Secondary endpoints included safety, tolerability, overall survival (OS), and multiple biomarkers, including serum Ang‐2. Results. Thirty patients were enrolled sequentially in each of the two nonrandomized cohorts. Demographics were comparable between the two arms and the historical controls. PFS rates at 4 months were 57% and 54% on the 10 mg/kg and 15 mg/kg trebananib cohorts, respectively. Median OS was 17 and 11 months, respectively. Grade 3 and above events noted in ≥10% of patients included fatigue, hypertension, diarrhea, liver failure, palmar‐plantar erythrodysesthesia syndrome, dyspnea, and hypophosphatemia. One

    Disturbed cell cycle-regulating checkpoints and impairment of genomic stability are key events during the genesis and progression of malignant tumors. We analyzed 80 epithelial ovarian tumors of benign (n = 10) and borderline type (n = 18) in addition to carcinomas of early (n = 26) and advanced (n = 26) stages for the expression of Ki67, cyclin A and cyclin E, p21WAF-1, p27KIP-1 and p53 and correlated the results with the clinical course. Genomic instability was assessed by DNA ploidy measurements and, in 35 cases, by comparative genomic hybridization. Overexpression of cyclin A and cyclin E was observed in the majority of invasive carcinomas, only rarely in borderline tumors and in none of the benign tumors. Similarly, high expression of p53 together with undetectable p21 or loss of chromosome arm 17p were frequent events only in adenocarcinomas. Both borderline tumors and adenocarcinomas revealed a high number of chromosomal gains and losses. However, regional chromosomal amplifications were found to occur 13 times more frequently in the adenocarcinomas than in the borderline tumors. The expression pattern of low p27 together with high Ki67 was found to be an independent predictor of poor outcome in invasive carcinomas. The results provide a link between disturbed cell cycle regulatory proteins, chromosomal aberrations and survival in ovarian carcinomas.

    Squamous cell carcinoma (SCC) of the uterine cervix and oral cavity are most common cancers in India. Telomerase reverse transcriptase (TERT) overexpression is one of the hallmarks for cancer, and activation through promoter mutation C228T and C250T has been reported in variety of tumors and often shown to be associated with aggressive tumors. In the present study, we analyzed these two hot spot mutations in 181 primary tumors of the uterine cervix and oral cavity by direct DNA sequencing and correlated with patient's clinicopathological characteristics. We found relatively high frequency of TERT hot spot mutations in both cervical [21.4 % (30/140)] and oral [31.7 % (13/41)] squamous cell carcinomas. In cervical cancer, TERT promoter mutations were more prevalent (25 %) in human papilloma virus (HPV)-negative cases compared to HPV-positive cases (20.6 %), and both TERT promoter mutation and HPV infection were more commonly observed in advanced stage tumors (77 %). Similarly, the poor and moderately differentiated tumors of the uterine cervix had both the TERT hot spot mutations and HPV (16 and 18) at higher frequency (95.7 %). Interestingly, we observed eight homozygous mutations (six 228TT and two 250TT) only in cervical tumors, and all of them were found to be positive for high-risk HPV. To the best of our knowledge, this is the first study from India reporting high prevalence of TERT promoter mutations in primary tumors of the uterine cervix and oral cavity. Our results suggest that TERT reactivation through promoter mutation either alone or in association with the HPV oncogenes (E6 and E7) could play an important role in the carcinogenesis of cervical and oral cancers.

    The objective was to report our experience with advanced stage oropharyngeal squamous cell carcinoma treated sequentially with induction chemotherapy followed by concurrent chemoradiotherapy. Retrospective chart review identified 49 eligible patients with advanced stage oropharyngeal squamous cell carcinoma treated with induction chemotherapy followed by concurrent chemoradiotherapy. HPV and p16(INK4A) testing was performed on pathology specimens. Follow-up of over 11 months was required unless a death or treatment failure occurred before that time. Treatment with induction chemotherapy followed by concurrent chemoradiotherapy resulted in 44/48 (90%) complete durable response. One death occurred from pulmonary embolism. Toxicity profiles were comparable to other published data. Average follow-up was 3.9 years. Oncologic failure rates among subgroups showed 5.7% failure for HPV+/p16+ cancer, 9.1% failure for HPV-/p16+ cancer, 100% failure for HPV-/p16- cancer, 0% failure for nonsmokers, and 17.9% failure for smokers. This study showed favorable outcomes in terms of durable oncologic response and acceptable toxicity profiles. It is notable that 36/49 patients were HPV+/p16+ and 11/49 were HPV-/p16+. Only 2 patients were HPV-/p16-, and both died as a result of oncologic failures. This highlights the importance of obtaining HPV and p16 testing in studies evaluating the efficacy of treatments for oropharyngeal squamous cell carcinoma.

    The data and regulatory considerations leading to the U.S. Food and Drug Administration (FDA) January 30, 2012 approval of Erivedge (vismodegib) capsules for the treatment of patients with recurrent, locally advanced, or metastatic basal cell carcinoma (BCC) are described. The FDA's approval decision was based primarily on the results observed in a single-arm, parallel cohort, international trial of vismodegib, administered orally at 150 mg daily until disease progression, in patients with pathologically confirmed, recurrent, locally advanced basal cell carcinoma (laBCC) or metastatic basal cell carcinoma (mBCC). An independent review committee confirmed an overall response rate (ORR) of 30.3% [95% confidence interval (CI): 15.6-48.2] in 33 patients with mBCC and an ORR of 42.9% (95% CI: 30.5-56.0) in 63 patients with laBCC; median response durations were 7.6 months and 7.6 months for patients with mBCC and laBCC, respectively. The most common adverse reactions were muscle spasms, alopecia, dysgeusia, weight loss, fatigue, nausea, diarrhea, decreased appetite, constipation, cough, arthralgias, vomiting, headache, ageusia, insomnia, and upper respiratory tract infection. Animal toxicology studies confirmed that vismodegib is a potent teratogenic agent. Approval was based on durable objective tumor responses supported by knowledge of the pathologic role of Hedgehog signaling in BCC and acceptable toxicity in a population without effective alternative therapies.

    Non-melanoma skin cancers (NMSCs) include a heterogeneous group of malignancies arising from the epidermis, comprising squamous cell carcinoma (SCC), basal cell carcinoma (BCC), Merkel cell carcinoma and more rare entities, including malignant pilomatrixoma and sebaceous gland tumours. The treatment of early disease depends primarily on surgery. In addition, certain patients present with extensive local invasion or metastasis, which renders these tumours surgically unresectable. Improving the outcome of radiotherapy through the use of concurrent systemic therapy has been demonstrated in several locally advanced cancer-treatment paradigms. Recently, agents targeting the human epidermal growth factor receptor (EGFR) have exhibited a consolidated activity in phase II clinical trials and case series reports. Cetuximab is a monoclonal antibody that binds to and completely inhibits the EGFR, which has been revealed to be up-regulated in a variety of SCCs, including NMSCs. The present review aimed to summarize the role of anti-EGFR agents in the predominant types of NMSC, including SCC and BCC, and focuses on the cetuximab-based studies, highlighting the biological rationale of this therapeutic option. In addition, the importance of the association between cetuximab and radiotherapy for locally advanced NMSC is discussed. PMID:27073643

    Treating extended prostatic small cell neuroendocrine carcinoma (PSCNC) is extremely difficult and no standard treatment has yet been established. We experienced a case of advanced mixed-type PSCNC in which the patient achieved long-term survival and local control following combined therapy. Locally advanced PSCNC causing lower urinary obstruction was detected during androgen-ablation therapy for stage D2 mixed adenocarcinoma PSCNC. The patient was treated with intra-arterial infusion chemotherapy using a reservoir system and external-beam radiotherapy (EBRT) to the whole pelvis and local tumor. After chemoradiotherapy, the patient's lower urinary obstruction was reduced and did not return during the remaining 40 months of the patient's life. The patient survived for 70 months following the start of the androgen-ablation therapy. The present study reports a useful treatment for advanced mixed-type PSCNC, androgen-ablation therapy and chemoradiotherapy. The present results also suggest that the prognostic factors for advanced mixed-type PSCNC are the sensitivity of the conventional adenocarcinoma to androgen-ablation therapy, degree of metastasis and extent of the small cell neuroendocrine carcinoma component.

    To determine the efficacy and toxicity of the protein kinase C inhibitor bryostatin-1 plus paclitaxel in patients with advanced pancreatic carcinoma. Each treatment cycle consisted of paclitaxel 90 mg/m by intravenous infusion over 1 hour on days 1, 8, and 16, plus bryostatin 25 mcg/m as a 1-hour intravenous infusion on days 2, 9, and 15, given every 28 days. Patients were evaluated for response after every 2 treatment cycles, and continued therapy until disease progression or prohibitive toxicity. The primary objective was to determine whether the combination produced a response rate of at least 30%. Nineteen patients with locally advanced or metastatic pancreatic adenocarcinoma received a total of 52 cycles of therapy (range: 1-10). Patients received the combination as first-line therapy for advanced disease (N = 5) or after prior chemotherapy used alone or in combination with local therapy. No patients had a confirmed objective response. The median time to treatment failure was 1.9 months (95% confidence intervals: 1.2, 2.6 months). Reasons for discontinuing therapy included progressive disease or death in 14 patients (74%) or because of adverse events or patient choice in 5 patients (26%). The most common grade 3 to 4 toxicities included leukopenia in 26%, anemia in 11%, myalgias in 11%, gastrointestinal bleeding in 11%, infection in 10%, and thrombosis in 10%. The combination of weekly paclitaxel and bryostatin-1 is not an effective therapy for patients with advanced pancreatic carcinoma.

    An overview of the responses to some of the most frequently asked questions regarding axitinib administration and dosage modifications used in clinical practice are presented. Axitinib was approved for second-line treatment of advanced renal cell carcinoma by the Food and Drug Administration on January 27, 2012. Inquiries received over the first six months after the approval date were reviewed. A large number of questions were related to administration of axitinib in different patient populations or in patients with various comorbidities, such as its (1) use in patients unable to swallow oral medication or administration of axitinib via a nasogastric tube, (2) use in patients with renal or hepatic impairment, (3) central nervous system penetration and use in patients with brain metastases, (4) drug interactions, particularly with anticoagulants, and (5) dosage modifications. Responses to these inquiries were provided based on the published literature or from data on file from the manufacturer. The dosage of axitinib can be adjusted for use in patients with hepatic impairment or in patients who cannot otherwise tolerate the usual regimen. Patients taking concomitant warfarin can also take axitinib, and patients who cannot swallow oral medications can receive a liquid formulation of the drug, though its efficacy and comparability to the tablet formulation has not been tested. Based on the published literature and company data on file, the axitinib dosage may be modified to accommodate patients with renal or hepatic impairment, who cannot swallow oral medication, are receiving concomitant warfarin, or who cannot otherwise tolerate the standard dosage regimen. For patients who cannot swallow, an oral suspension can be prepared because crushing axitinib is not recommended. Copyright © 2014 by the American Society of Health-System Pharmacists, Inc.

    To estimate the cost-effectiveness of sorafenib (Nexavar, Bayer, Leverkusen, Germany) versus best supportive care (BSC) for second-line treatment of advanced renal cell carcinoma from the perspective of the UK National Health Service. A decision analytic model was developed to estimate the cost-effectiveness of sorafenib. The clinical effectiveness of sorafenib versus BSC was taken from a recent randomized phase III trial. Utility values were taken from a phase II trial of sunitinib, using EQ-5D tariffs. Cost data were obtained from published literature and were based on current UK practice. The effect of parameter uncertainty on cost-effectiveness was explored through extensive one-way and probabilistic sensitivity analyses. Compared to BSC, sorafenib treatment resulted in an incremental cost per quality-adjusted life year (QALY) gained of pound75,398, based on an estimated mean gain of 0.27 QALYs per patient, at a mean additional cost of pound20,063 (inflated to 2007/2008). The probability that sorafenib is cost-effective compared to BSC at a willingness to pay threshold of pound30,000 per QALY is 0.0%. In sensitivity analysis, estimates of cost per QALY were sensitive to changes in the clinical effectiveness parameters, and to health state utilities and drug costs. Sorafenib has been shown to be clinically effective compared to BSC, offering additional health benefits; however, with a cost per QALY in excess of pound70,000, it may not be regarded as a cost-effective use of resources in some health-care settings.

    Purpose: To analyze which patient-, tumor-, and treatment-related factors may influence outcome after {sup 90}Y radioembolization ({sup 90}Y-RE) for hepatocellular carcinoma (HCC). Patients and Methods: Seventy-two consecutive patients with advanced HCC treated with {sup 90}Y-RE were studied to detect which factors may have influenced response to treatment and survival. Results: Median overall survival was 13 months (95% confidence interval, 9.6-16.3 months). In univariate analysis, survival was significantly better in patients with one to five lesions (19 vs. 8 months, p = 0.001) and in patients with alpha-fetoprotein <52 UI/mL (24 vs. 11 months, p = 0.002). The variation in target tumor size and the appearance of new lesions were analyzed among 50 patients with measurable tumors. A decrease in target tumor size was observed in most patients, and the intensity of such decrease was not associated with any of the factors under study. Patients who developed new lesions in the treated liver (and also in the nontargeted liver) at month 3 more frequently had more than five nodules, bilobar disease, and alpha-fetoprotein >52 UI/mL, and their survival in the multivariate analysis was significantly worse (hazard ratio, 4.7; 95% confidence interval, 13-1.73) (p = 0.002). Conclusions: Yttrium-90 radioembolization results in control of target lesions in the majority of patients with HCC but does not prevent the development of new lesions. Survival of patients treated with {sup 90}Y-RE seems to depend largely on factors related to the aggressiveness of the disease (number of nodules, levels of alpha-fetoprotein, and presence of microscopic disease).

    Over the last 2 decades, survival from laryngeal cancer has decreased. We sought to identify factors associated with decreased survival in laryngeal cancer. Patients diagnosed with laryngeal squamous cell carcinoma from 1985 to 2002 were retrospectively reviewed. A total of 451 patients met study criteria. Five-year survival rates were 85% for stage I, 77% for stage II, 51% for stage III, and 35% for stage IV disease. Survival for patients with stage I-III disease was similar for patients treated operatively or nonoperatively (P = .4). However, patients with stage III disease treated nonoperatively had worse survival with radiation alone (XRT) compared to chemoradiation (CR) (P = .006). Patients with stage IV disease had significantly better survival with surgery (49%) than CR (21%) or XRT alone (14%) (P < .0001). Analysis by primary tumor stage demonstrated that survival for T1-T3 disease was independent of treatment modality (P = .2); however, for T4 patients, operative treatment was associated with significantly better survival (55%) than CR (25%) or XRT (0%) (P < .0001). Proportional hazards models confirmed significantly worse survival for stage IV, T4, N2 or N3 disease, and nonoperative treatment. For T4 disease, after controlling for nodal status, nonoperative treatment was the only significant predictor of worse survival. Primary surgical treatment is associated with improved survival for patients with stage IV disease and specifically T4 primary tumors. These data suggest that the observed national decrease in survival from laryngeal cancer may be due to a shift toward nonoperative treatment in that subset of patients with advanced primary disease.

    Background: Locally advanced pancreatic carcinoma (LAPC) is characterized by poor prognosis despite recommended concurrent chemoradiotherapy. Irreversible electroporation (IRE) has emerged as a potential option for the management of unresectable pancreatic cancer. This study was conducted to evaluate the safety and short-term efficacy of open IRE for the treatment of LAPC. Methods: Retrospective data of 25 consecutive patients receiving IRE for T3 lesions from July 2015 to June 2016 at a single center were analyzed. The perioperative and long-term IRE-related complications were reviewed to evaluate the safety of the procedure. The tumor reduction and biological response were analyzed through computed tomography/magnetic resonance imaging; the serum level of CA19-9 was measured as a secondary endpoint to evaluate the short-term efficacy of IRE. Results: All patients were successfully treated; the median tumor size was 4.2 cm and the median IRE time was 36 min. Four intraoperative procedure-related complications were observed (16%): two transient hypertensive episodes, one hypotension case, and one transient supraventricular tachycardia case. Nine postoperative complications were described, including three Grade A pancreatic fistulas, three delayed gastric emptying, one acute pancreatitis, one upper gastrointestinal hemorrhage, and one portal vein thrombosis. The overall rate of stable disease was 28%, 36% achieved partial response, and lower serum CA19-9 levels were recorded in all patients at discharge. Conclusions: IRE is feasible for the treatment of LAPC and is a reasonable intervention strategy owing to its combined attributes of safety and efficacy. PMID:27958223

    The management of renal cell carcinoma (RCC) has undergone significant changes during the past 10 years, with the treatment of metastatic RCC undergoing the most radical changes. These developments reflect an enhanced understanding of this tumor's underlying biology, which was then translated into the development of a new treatment paradigm. Current therapeutic approaches for the management of patients with metastatic RCC utilize knowledge of histology, molecular abnormalities, clinical prognostic factors, the natural history of this malignancy, and the treatment efficacy and toxicity of available agents. The treatment options available for patients with metastatic RCC have changed dramatically over the past 6 years. Interferon-α and interleukin-2 were the previous mainstays of therapy, but since December 2005, six new agents have been approved in the US for the treatment of advanced RCC. Three are multi-targeted tyrosine kinase inhibitors (TKI) including sunitinib, sorafenib, and pazopanib, two target the mammalian target of rapamycin (temsirolimus and everolimus), and one is a humanized monoclonal antibody (bevacizumab in combination with interferon-α). The current review focuses on the newest TKI available to treat patients with metastatic RCC, pazopanib. The development of this agent both preclinically and clinically is reviewed. The efficacy and safety data from the pivotal clinical trials are discussed, and the potential role of pazopanib in the treatment of patients with metastatic RCC in comparison to other treatment alternatives is critically appraised. This agent has a favorable overall risk benefit, and the available data demonstrate efficacy in patients with metastatic RCC who are either treatment-naïve or cytokine refractory. It therefore represents another alternative for treatment of metastatic RCC patients.

    AIM To evaluate the inhibitory effects of deferasirox (DFX) against hepatocellular carcinoma (HCC) through basic and clinical studies. METHODS In the basic study, the effect of DFX was investigated in three hepatoma cell lines (HepG2, Hep3B, and Huh7), as well as in an N-nitrosodiethylamine-induced murine HCC model. In the clinical study, six advanced HCC patients refractory to chemotherapy were enrolled. The initial dose of DFX was 10 mg/kg per day and was increased by 10 mg/kg per day every week, until the maximum dose of 30 mg/kg per day. The duration of a single course of DFX therapy was 28 consecutive days. In the event of dose-limiting toxicity (according to the Common Terminology Criteria for Adverse Events v.4.0), DFX dose was reduced. RESULTS Administration of DFX inhibited the proliferation of hepatoma cell lines and induced the activation of caspase-3 in a dose-dependent manner in vitro. In the murine model, DFX treatment significantly suppressed the development of liver tumors (P < 0.01), and significantly upregulated the mRNA expression levels of hepcidin (P < 0.05), transferrin receptor 1 (P < 0.05), and hypoxia inducible factor-1α (P < 0.05) in both tumor and non-tumor tissues, compared with control mice. In the clinical study, anorexia and elevated serum creatinine were observed in four and all six patients, respectively. However, reduction in DFX dose led to decrease in serum creatinine levels in all patients. After the first course of DFX, one patient discontinued the therapy. We assessed the tumor response in the remaining five patients; one patient exhibited stable disease, while four patients exhibited progressive disease. The one-year survival rate of the six patients was 17%. CONCLUSION We demonstrated that DFX inhibited HCC in the basic study, but not in the clinical study due to dose-limiting toxicities.

    Background and Aims In this pilot study, we assessed the safety and tolerability of combining sorafenib with 90Y radioembolization for the treatment of unresectable hepatocellular carcinoma (hcc). Methods The study, conducted prospectively during 2009–2012, included eligible patients with unresectable hcc and a life expectancy of at least 12 weeks. Each patient received sorafenib (400 mg twice daily) for 6–8 weeks before 90Y treatment. Safety and tolerability were assessed. Results Of the 40 patients enrolled, 29 completed treatment (combined therapy). In the initial cohort, the most common cause of hcc was hepatitis C (32.5%), and most patients were staged Child A (82.5%). The 29 patients who co
