    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.

    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

    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.

    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.

    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.

    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

    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

    Purpose: 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). Methods and Materials: 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{sup 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. Results: 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). 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.

    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.

    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.

    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.

    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.

    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.

  8. Total and lipid-bound serum sialic acid as markers for carcinoma of the uterine cervix.

    1992-08-01

    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.

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.

    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.

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.

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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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.

    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.

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.

    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

    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.

    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.

    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

    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.

    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.

    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

    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

    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.

    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

    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

    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.

    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.

    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.

    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.

    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 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.

    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.

    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

    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.

    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

    Purpose: To evaluate disease outcomes and toxicity in cervical cancer patients treated with pelvic intensity-modulated radiation therapy (IMRT). Methods and Materials: 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. Results: 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. Conclusions: 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.

    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

    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.

    Purpose: To report response rate, pelvic tumor control, survival, and late toxicity after treatment with combined radiotherapy and hyperthermia (RHT) for patients with locally advanced cervical carcinoma (LACC) and compare the results with other published series. 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.

    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.

    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%.

    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

    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).

    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.

    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.

    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

    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

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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

  17. 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.

    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.

    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.

  20. 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.

    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

    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 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

    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.

    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.

    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

    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.

    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.

    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. The received dose intensity was 91% of that projected. Docetaxel is an active drug against advanced

    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.

    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.

    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.

    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.

    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

    Immunohistochemical studies in cervical intraepithelial neoplasia and cervical carcinoma are evaluated in this review. A variety of proteins like p53, bcl2, C-Myc, Ki 67, Cyclines, P16 INK4a, p21, p27, beta-catenin, Wnt and MCM, have been related to the development of cervical neoplasia and human papilloma virus infection. It is described how transcriptional factors of genes induce loss of heterozygosity, numerical chromosome abnormality and inactivation of gene products or the partial loss of some membrane glycoproteins induced by oncogenic human papillomaviruses (HPV).

    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.

    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.

    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.

    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.

    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.

    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 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.

    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.

    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.

    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.

    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

    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.

    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

    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.

    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.

    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

    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.

    Purpose: To assess the toxicity profile of erlotinib therapy combined with postoperative adjuvant radiation therapy in patients with advanced cutaneous squamous cell carcinoma. Methods and Materials: 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. Results: 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%. Conclusions: 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.

    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

    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.

    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.

    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

    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.

    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

    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.

    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.

    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

    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.

    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.

    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.

    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

    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

    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.

    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

    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.

    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

    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.

    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

    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 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.

    This study aimed to evaluate the utility of dynamic contrast-enhanced ultrasound (DCE-US) in measuring early tumor response of advanced hepatocellular carcinoma to axitinib. Twenty patients were enrolled (aged 18-78 y; median 65). DCE-US was performed with bolus injection and infusion/disruption replenishment. Median overall survival was 7.1 mo (1.8-27.3) and progression free survival was 3.6 mo (1.8-17.4). Fifteen patients completed infusion scans and 12 completed bolus scans at 2 wk. Among the perfusion parameters, fractional blood volume at infusion (INFBV) decreased at 2 wk in 10/15 (16%-81% of baseline, mean 47%) and increased in 5/15 (116%-535%, mean 220%). This was not significantly associated with progression free survival (p = 0.310) or progression at 16 wk (p = 0.849), but was borderline statistically significant (p = 0.050) with overall survival, limited by a small sample size. DCE-US is potentially useful in measuring early tumor response of advanced hepatocellular carcinoma to axitinib, but a larger trial is needed.

    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.

    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.

    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.

    2015-01-01

    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.

    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.

    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.

  10. 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

    2016-01-01

    Background. 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). Materials and Methods. 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. Results. 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%). Conclusion. 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. Implications for Practice: 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

    2015-01-01

    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

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.

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

    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.

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 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

    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.

    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.

    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.

    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.

    2017-01-01

    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.

    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.

    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.

    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.

    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.

    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.

    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

    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

    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

    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.

    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

    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.

    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

    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

    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.

    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: 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.

    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

    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.

    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.

    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.

  18. 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.

    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.

    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

    2017-01-01

    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

    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

    2016-01-01

    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.

    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.

    2006-02-01

    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.

  6. Present and future perspectives on immunotherapy for advanced renal cell carcinoma: Going to the core or beating around the bush?

    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.

    The metastatic potential patterns of dissemination have been investigated in 150 patients with Stage 1B adenocarcinoma of the cervix treated during a 20-year period from 1956 to 1977. All cases with the exception of one were treated with a combination of intracavitary radium implants followed by a radical surgical procedure with pelvic lymph node dissection. It was found that the incidence of pelvic metastases and distant recurrences and the survival rates were the same as in previously published reports for squamous cell carcinomas treated in the same manner. In one respect adenocarcinomas showed a significant difference when compared with squamous cell cancers: The incidence of residual tumor in the hysterectomy specimens after intracavitary treatment was much higher (30% versus 11%). This is considered a strong argument for surgical treatment of patients with early stages of adenocarcinoma of the cervix.

    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.

    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.

    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).

    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.

    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

    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 completed the study had similar baseline characteristics. Grades 1 and 2 toxicities accounted for 77.8% of all adverse events reported. The most common toxicities reported were fatigue (19.0%), alteration in liver function (7.9%), and diarrhea (6.3%). There were 12 grade 3 and 2 grade 4 toxicity events reported. One patient died of liver failure within 30 days after treatment. During the study, the sorafenib dose was reduced in 6 patients (20.7%), and sorafenib had to be interrupted in 4 patients (13.8%) and discontinued in 4 patients (13.8%). The disease control rate was 72.4% per the modified Response Evaluation Criteria in Solid Tumors, and tumour necrosis was observed in 82.8% of patients. Overall survival in patients undergoing combined therapy was 12.4 months. Conclusions Preliminary results demonstrate the safety and tolerability of combining 90Y radioembolization and sorafenib for advanced hcc. A larger prospective study is needed to determine the extent of the survival benefit. PMID:27803608

    2016-01-01

    Background Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. Summary This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques. Key Message Advances in image-guided locoregional therapies, including local ablative therapy and transarterial therapy, have led to a major breakthrough in the management of HCC. Both survival rates and cure rates of patients with HCC have improved markedly since the introduction of these techniques. Practical Implications Radiofrequency ablation is currently considered as an alternative to surgical resection for patients with early-stage HCC. A newer technique of ablation such as microwave ablation is increasingly being used, especially for large HCC. Transarterial chemoembolization has become a standard care for asymptomatic patients with multinodular tumors in intermediate-stage disease, and transarterial radioembolization has become the method of choice in HCC cases with portal vein thrombosis. Moreover, combination treatment modalities, such as thermal-based ablation combined with transarterial chemoembolization or 125I seed implant brachytherapy, may further broaden their clinical indications for HCC. Moreover, use of localized radiation in combination with thermal ablation has been reported to improve tumor control and long-term survival. PMID:27904861

    Background and aim To evaluate the impact of percutaneous endoscopic gastrostomy (PEG) tube on nutritional status, treatment-related toxicity, and treatment tolerance in patients with locally advanced nasopharyngeal carcinoma (NPC) who underwent chemoradiotherapy. Patients and methods We enrolled 133 consecutive non-metastatic NPC (III/IV stage) patients, who were treated with prophylactic PEG feeding before the initiation of concurrent chemoradiotherapy (CCRT) between June 1, 2010 and June 30, 2014. Meanwhile, another 133 non-PEG patients, who were matched for age, gender, and tumor, node, metastases stage, were selected as historical control cohort. Weight and nutritional status changes from pre-radiotherapy to the end of radiotherapy were evaluated, and treatment tolerance and related acute toxicities were analyzed as well. Results We found that significantly more patients (91.73%) in the PEG group could finish two cycles of CCRT, when compared with those in the non-PEG group (57.89%) (P<0.001). We also indicated that more patients (50.38%) in the non-PEG group experienced weight loss of ≥5%, while the phenomenon was only found in 36.09% patients in the PEG group (P=0.019). In addition, the percentage of patients who lost ≥10% of their weight was similar in these two groups. Changes in albumin and prealbumin levels during radiotherapy in the non-PEG group were higher than those obtained for the PEG group with significant differences (P-values of 0.023 and <0.001, respectively). Furthermore, patients in the PEG group had significantly lower incidence of grade III acute mucositis than those in the non-PEG group (22.56% vs 36.84%, P=0.011). Tube-related complications occurred only in 14 (10.53%) patients in the PEG group, including incision infection of various degrees. Conclusion PEG and intensive nutrition support may help to minimize body weight loss, maintain nutritional status, and offer better treatment tolerance for patients with locally advanced NPC who

    We investigated a new chemoradiotherapy (CRT) regimen for locoregionally advanced nasopharyngeal carcinoma (NPC). A total of 240 patients were randomly assigned to three different CRT regimens: sequential CRT [1 cycle chemotherapy + Phase I radiotherapy (RT) + 1 cycle chemotherapy + Phase II RT + 2 cycles chemotherapy] with a cisplatin-gemcitabine (GC) regimen (800 mg/m(2) gemcitabine on Days 1 and 8 and 20 mg/m(2) cisplatin on Days 1-5, every 4 weeks) (sGC-RT); sequential chemoradiotherapy with a cisplatin-fluorouracil (PF) regimen (20 mg/m(2) DDP and 500 mg/m(2) 5-FU on Days 1-5, every 4 weeks) (sPF-RT) and cisplatin-based concurrent chemoradiotherapy plus adjuvant PF chemotherapy (Con-RT + PF). The complete response rate was higher in the sGC + RT group than in the other two groups (98.75% vs. 92.50%, p < 0.01). The 3-year overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) rates in the sGC-RT group were significantly higher than those observed in the Con-RT group (OS, 95.0% vs. 76.3%, p < 0.001; DFS, 89.9% vs. 67.5%, p < 0.001; DMFS, 92.5% vs. 76.0%, p = 0.004) and in the sPF + RT group (OS, 95.0% vs. 73.6%, p < 0.001; DFS, 89.9% vs. 63.3%, p < 0.001; DMFS, 92.5% vs. 74.7%, p = 0.002). There were no significant differences in 3-year OS, DFS and MFS rates between the Con-RT and the sPF-RT groups. The GC-RT group experienced more hematologic toxicity, constipation and rash; however, there were no differences in late RT toxicity between the groups. These results demonstrate that a sGC-RT regimen is effective and well tolerated in patients with locoregionally advanced NPC.

    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.Patients with advanced stage tumors of the

    Anticancer agents may trigger reactivation of hepatitis B virus infection ensuing in asymptomatic to severe liver damage. Preemptive administration of antiviral agents such as lamivudine to patients receiving cytotoxic chemotherapy has been shown to inhibit viral replication and prevent such events. No data are available so far concerning the coadministration of antiviral agents and everolimus, an oral mammalian target of rapamycin inhibitor recently approved for the treatment of advanced renal cell carcinoma. We present in this study the first case to our knowledge of a hepatitis B surface antigen-positive patient with metastatic renal cell carcinoma who has been successfully treated with prophylactic lamivudine and everolimus. Long-term depletion of viral replication was obtained along with stabilization of lung and bone metastases. Hepatitis B surface antigen positivity may be found in up to 10% of cancer patients but should not be considered a contraindication to treatment with everolimus.

    The present paper reports the chemopreventive action of mace (aril covering the testa of the seed of Myristica fragrans) on 3-methylcholanthrene (MCA)-induced carcinogenesis in the uterine cervix of virgin, young adult, Swiss albino mice. Placement of cotton-thread impregnated with beeswax containing MCA (approximately 600 micrograms) inside the canal of the uterine cervix results in the appearance of precancerous and cancerous lesions in the cervical epithelium. In this experiment using the cervical carcinogenesis model system, if mace was administered orally at the dose level of 10 mg/mouse per day for 7 days before and 90 days following carcinogen thread insertion, the cervical carcinoma incidence, as compared with that of the control (73.9%), was 21.4%. This decline in the incidence of carcinoma was highly significant (P less than 0.001). The incidence of precancerous lesions did not display any definite association with different treatments.

    The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

    Background & Aims Interferon reportedly decreases the incidence of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C. The Hepatitis C anti-viral long-term treatment against cirrhosis (HALT-C) trial showed that 4 years of maintenance therapy with peginterferon does not reduce liver disease progression. We investigated whether peginterferon decreases the incidence of HCC in the HALT-C cohort over a longer post-treatment follow-up period. Methods The study included 1,048 patients with chronic Hepatitis C (Ishak fibrosis scores ≥3) who did not have a sustained virological response (SVR) to therapy. They were randomly assigned to groups given a half-dose of peginterferon or no treatment (controls) for 3.5 years and followed for a median 6.1 (maximum 8.7) years. Results Eighty-eight patients developed HCC (68 definite, 20 presumed): 37/515 that were given peginterferon (7.2%) and 51/533 controls (9.6%; P=0.24). There was a significantly lower incidence of HCC among patients given peginterferon therapy who had cirrhosis, but not fibrosis, based on analysis of baseline biopsy samples. After 7 years, the cumulative incidences of HCC in treated and control patients with cirrhosis were 7.8% and 24.2%, respectively (hazard ratio [HR]=0.45; 95% confidence interval [CI]: 0.24–0.83); in treated and control patients with fibrosis they were 8.3% and 6.8%, respectively (HR=1.44; 95% CI: 0.77–2.69). Treated patients with a ≥2-point decrease in the histologic activity index, based on a follow-up biopsy, had a lower incidence of HCC than those with unchanged or increased scores (2.9% vs. 9.4%; P=0.03). Conclusions Extended analysis of the HALT-C cohort showed that long-term peginterferon therapy does not reduce the incidence of HCC among patients with advanced hepatitis C who did not achieve SVRs. Patients with cirrhosis who received peginterferon treatment had a lower risk for HCC than controls. PMID:21129375

    Primary cutaneous apocrine carcinoma (PCAC) is a rare and highly aggressive cutaneous adnexal type of tumor that has a high metastasis rate and a poor prognosis. Although there are several case reports describing the successful treatment of PCAC with chemoradiotherapy or molecular targeting therapy, no standard therapy for the treatment of advanced PCAC has been established yet. Since receptor activator of nuclear factor kappa-B ligand (RANKL) is expressed in cancers of apocrine origin, leading to immunosuppression at the tumor site, we hypothesized that targeting RANKL with denosumab might be useful for the treatment of PCAC. In this report, we describe a case with advanced PCAC on the scrotum successfully treated with systemic chemotherapy using carboplatin and paclitaxel, and radiotherapy followed by denosumab.

    Sorafenib is an oral multikinase inhibitor that has been approved to treat advanced hepatocellular carcinoma (HCC), though it is unclear how much benefit advanced HCC patients with progressive disease (PD) derive from sorafenib treatment. This study aimed to assess survival risk factors and evaluate therapeutic strategies for advanced HCC patients with PD after sorafenib treatment. We analyzed the clinical data and treatment outcomes for 315 consecutive advanced HCC patients treated with sorafenib. Univariate analyses of overall survival identified therapeutic effect as an independent risk factor in all patients. Among all patients, 141 developed PD. Of those, 58 (41%) were treated with sorafenib monotherapy, 70 (50%) with agents other than sorafenib, and 13 (9%) were not treated at all. The median survival time was 6.1 months for PD patients with sorafenib monotherapy and 12.2 months for those administered alternative treatments (p < 0.0001). Our results indicated that sorafenib treatment may have negative long-term therapeutic effects in advanced HCC patients with PD, and that alternative treatments should be considered for these patients after sorafenib administration.

    The purpose of the present study was to investigate whether genetic variants that influence angiogenesis and sorafenib pharmacokinetics are associated with clinical outcomes and toxic effects in advanced renal cell carcinoma patients treated with this drug. One hundred patients with advanced renal cell carcinoma were enrolled. Forty-two polymorphisms in 15 genes were selected for genotyping and analyzed for associations with progression-free survival, overall survival, and toxic effects. We found that rs1570360 in VEGF and rs2239702 in VEGFR2 were significantly associated with progression-free. Specifically, patients carrying the variant genotypes (AG + AA) of these two polymorphisms both had an unfavorable progression-free. In addition, compared with those with the rs2239702 GG genotype, patients with the AG + AA genotype suffered an unfavorable OS. We found that the VEGF rs2010963 CG + GG genotypes had a significantly increased risk of hand-foot syndrome, and the ABCB1 rs1045642 CT + TT genotypes had an increased risk of high blood pressure. Our results suggest that polymorphisms in VEGF and VEGFR2 are associated with sorafenib clinical outcomes, and polymorphisms in VEGF and ABCB1 are associated with sorafenib-related toxicities. Larger studies are warranted to validate our findings. PMID:26830973

    The aim of this study was to evaluate the predictive value of magnetic resonance imaging (MRI) in detecting thyroid gland invasion (TGI) in patients with advanced laryngeal or hypopharyngeal carcinoma. In a retrospective chart review, 41 patients with advanced laryngeal or hypopharyngeal carcinoma underwent MRI scan before total laryngectomy and ipsilateral or bilateral thyroidectomy during the past 5 years. The MRI findings were compared with the postoperative pathological results. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Among the 41 patients, 3 had thyroid gland invasion in postoperative pathological results. MRI correctly predicted the absence of TGI in 37 of 38 patients and TGI in all 3 patients. The sensitivity, specificity, PPV, and NPV of MRI were 100.0, 97.4, 75.0, and 100 %, respectively, with the diagnostic accuracy of 97.6 %. In consideration of the high negative predictive value of MRI, it may help surgeons selectively preserve thyroid gland in total laryngectomy and reduce the incidence of hypothyroidism and hypoparathyroidism postoperatively.

    Health-related quality of life (QoL) is a goal in nutritional oncology but the association between nutritional status and QoL is rarely explored. The aim of the study was to investigate the association of nutritional assessment criteria with QoL in 50 patients with advanced colorectal carcinoma. A second aim was to investigate changes in body weight and QoL during a 3-month follow-up. Muscle mass, nutritional risk, malnutrition and cachexia according to three different criteria were assessed, as well as health-related QoL. At inclusion, 36 patients experienced weight loss, 10 patients sarcopenia, 25 were at nutritional risk, 16 were malnourished and 11, 14 and 31 patients had cachexia according to different criteria. All nutritional assessment criteria discriminated between groups of patients with worse or better QoL to varying degrees. Malnutrition and cachexia defined by the European Palliative Care Research Collaborative and adjusted for recent gain or stabilisation of body weight discriminated on most QoL scores. Weight loss at follow-up was associated with a decrease in several QoL scores. Recognition of weight loss as well as diagnosing malnutrition and cachexia should be the first steps in an interventional pathway to enhance nutritional status and QoL in patients with advanced colorectal carcinoma.

    The present study investigated clinical outcomes and prognostic factors of patients with locally advanced synchronous esophageal squamous cell carcinoma (ESCC) and head/neck squamous cell carcinoma (HNSCC) receiving curative concurrent chemoradiotherapy (CCRT), and determined whether synchronous ESCC/HNSCC patients had worse prognosis compared to isolated ESCC patients. Using propensity score matching method, we compared 60 locally advanced synchronous ESCC/HNSCC patients with 60 matched isolated ESCC patients. Compared to 60 matched isolated ESCC patients, synchronous ESCC/HNSCC patients had significantly worse prognosis (13.5 months versus 17.2 months, P = 0.01), more grade 3–4 CCRT toxicity, and higher percentage of CCRT interruption. For synchronous ESCC/HNSCC group, the 1-year and 2-year survival rates were 52% and 13%, respectively. Univariate analysis showed that early ESCC stage, non-T4b disease, and salvage operations were significantly associated with superior survival. In multivariate analysis, ESCC stage represented an independent prognosticator. For chemotherapy regimen during CCRT, cisplatin/5-fluorouracil had significantly more grade 3–4 mucositis/esophagitis and neutropenia than weekly cisplatin. In conclusion, synchronous ESCC/HNSCC patients receiving curative CCRT have worse prognosis and poorer compliance of CCRT compared to isolated ESCC patients. For these patients, ESCC stage and T4b disease were significantly associated with clinical outcomes, and salvage operation may improve overall survival. PMID:28134308

    The combination of radiotherapy and surgery in the treatment of advanced oral carcinoma (T3 and T4 lesions) yields good possibilities of recovery; whether radiotherapy should be given before or after surgery is still debated. Fifty patients with advanced oral carcinomas were analyzed: 24 of them were irradiated before and 26 after surgery; doses ranged from 40 to 56 Gy for the first group of patients, and from 50 to 68 Gy for the second one. The disease-free survival 48 months after the diagnosis was 36% in patients who received preoperative irradiation, and 53.6% in patients who received postoperative radiotherapy; the latter allowed local control of the disease to be significantly improved (chi 2 3.99, 0.01 less than p less than 0.05). The quality of survival was worse in the group receiving preoperative irradiation, because of radiation-induced surgical complications, which were especially observed in patients with diffuse disease. Our findings suggest that postoperative radiotherapy may be advisable if the tumor is resectable, since tolerance and local control rate were acceptable. On the contrary, nearly inoperable masses and massive neck diseases often require preoperative irradiation.

    Background: 95% of Tuberculosis (TB) of the female genital tract (FGT) is located in tissues other than the cervix. A rare case of primary TB of the cervix which was diagnosed coincidently in a patient of endometrioma was reported in this study. Case Presentation: A 34 year old nullipara, a diagnosed case of endometrioma had a small cervical growth. Pap smear and biopsy was taken and sent for histopathological examination. Her histopathological examination revealed multiple epitheloid cell granuloma and langerhans type giant cell caeseation. Ziehl neelsen staining was positive for acid fast bacilli (AFB). The patient was started on antituberculosis under directly observed therapy along with oral contraceptive pills. Patient was on regular follow-up and clinically she was doing well. Conclusion: Although cervical tuberculosis is very rare but for an abnormal looking cervix, cervical tuberculosis should be considered in the differential diagnosis in woman of all the age groups especially in areas where tuberculosis is rampant since these cases are potentially curable with medical therapy. Many of these patients are in reproductive age group. In young women, early diagnosis prevents further damage in reproductive tract and can improve their reproductive potential. PMID:27921005

The approval was based on efficacy and safety data demonstrated in an open-label, randomized study of 821 patients with advanced RCC who progressed after at least one anti-angiogenic therapy. Patients were randomized to nivolumab or everolimus and followed for disease progression. The primary end point was overall survival. Subsequent therapies, including everolimus for patients who developed progressive disease on the nivolumab arm, were allowed, but no cross-over was permitted. The median overall survival was 25.0 months on the nivolumab arm and 19.6 months on everolimus arm (hazard ratio: 0.73; 95% confidence interval: 0.60-0.89). The confirmed response rates were 21.5% versus 3.9%; median durations of response were 23.0 versus 13.7 months, and median times to response were 3.0 versus 3.7 months in the nivolumab and everolimus arms, respectively. A statistically significant improvement in progression-free survival was not observed in this trial. The safety profile of nivolumab in renal cell cancer was similar to that in other disease settings. However, the incidence of immune-mediated nephritis appeared to be higher in patients with RCC. The Oncologist 2017;22:311-317 IMPLICATIONS FOR PRACTICE: The overall benefit/risk profile demonstrated in trial CA209025 supported the approval of nivolumab as an additional treatment option for patients with advanced renal cell carcinoma after anti-angiogenic therapy. The use of nivolumab in patients who had received vascular endothelial growth factor-targeted therapy resulted in a 5.4 month improvement in median overall survival compared with the everolimus arm. This difference is statistically significant and clinically meaningful.

    One-hundred and thirty-two patients with cervix carcinoma who were treated with whole pelvis irradiation and two intracavitary applications had bladder and rectal dosimetry during brachytherapy with contrast agents placed into the bladder and rectum prior to orthogonal simulator radiographs. Doses were computer calculated at points A and B, F (bladder), R1 (rectum), and R2 (rectosigmoid). Late occurring bladder and rectal complications were graded on a severity scale of 1 to 3, and 14% had grade 2 or 3 injuries (9% developed fistulas). Statistical evaluation of the data showed that severe bladder and rectal injuries occur more commonly in stage IIIA and IIIB disease and in those receiving high external beam doses (5000 rad +). Analysis of variance tests revealed a significant correlation of brachytherapy dose to points R1 and R2 with severe rectal injuries but there was not a correlation of dose to F with bladder injuries. Nor was there correlation of injuries with dose to point A or the milligram-hour dose. We conclude that our technique for rectal dosimetry is adequate but that an improved technique of bladder dosimetry is needed. Also, when combining whole pelvis irradiation with two intracavitary applications (4000 rad to point A), the whole pelvis dose should probably not exceed 4000-4500 rad.

    The outcome of patients with metastatic renal cell carcinoma has been substantially improved with administration of the currently available molecularly targeted therapies. However, proper selection of therapy and management of toxicities remain challenging. NCCN convened a multidisciplinary task force panel to address the clinical issues associated with these therapies in attempt to help practicing oncologists optimize patient outcomes. This report summarizes the background data presented at the task force meeting and the ensuing discussion. PMID:21335444

    This paper presents the results of treatment on 99 patients with squamous cell carcinoma of the oropharynx irradiated by the twice-a-day radiation therapy program at the Massachusetts General Hospital. The program consisted of 1.6 Gy per fraction, two fractions per day with 4 hours between fractions, for 12 days, 5 days a week. After 38.4 Gy, the patients were given a 2 week break and then resumed twice-a-day radiation therapy for a total of 64 Gy and occasionally 67.2 Gy. Fifty-two patients had carcinoma of the faucial tonsil and 47 patients had carcinoma of the base of the tongue. For the entire group of patients, the 36 month actuarial local control rate was 58%, and for the T1-2 and T3-4 lesions, the rates were 77% and 48% respectively. In comparison with patients treated by once-a-day radiation therapy for a few years immediately prior to the twice-a-day program, the local control rates were improved to a statistically significant level. Likewise, the results as compared to those published in the literature were no worse and perhaps superior to those of patients treated by the once-a-day schedule.

    Hepatitis C infection is associated with the development of hepatocellular carcinoma, and progress has been made in a number of areas. Transgenic mice lines expressing the hepatitis C core protein develop hepatic steatosis, adenomas, and hepatocellular carcinomas, with no significant hepatitis or fibrosis. This implies that hepatitis C can lead directly to malignant transformation. A new lesion, irregular regeneration, has been described in chronic hepatitis C infection and is associated with a 15-fold increase in the relative risk of developing hepatocellular carcinoma. A minority of patients with hepatitis C-related hepatocellular carcinoma have intense lymphocytic infiltration of the cancer, a feature associated with a better prognosis. Several studies have confirmed the association between large cell dysplasia and hepatocellular carcinoma. However, large cell dysplasia may not be a premalignant lesion and instead may be a marker for premalignant alterations elsewhere in the liver. Oral contraceptives previously have been linked to an increased risk of hepatocellular carcinoma. A large multicenter European case-control study has shown minimal increased risk of hepatocellular carcinoma with use of steroidal contraception. Tamoxifen had shown promise in the management of advanced hepatocellular carcinoma. However, a randomized placebo-controlled study of 477 patients with hepatocellular carcinoma found no benefit from tamoxifen. In a preliminary study, however, octreotide has shown improved survival and quality of life in patients with advanced hepatocellular carcinoma. Finally, interferon treatment continues to be linked to a reduced risk of hepatocellular carcinoma in patients with hepatitis C. These studies generally are not randomized, and a randomized prospective study is required to address this issue.

    Introduction We investigated relationships between treatment characteristics and long-term outcomes in patients with locally advanced thymoma or thymic carcinoma. Methods We retrospectively reviewed 146 patients treated in 1980–2011 at two tertiary cancer care centers, 110 with Masaoka-Koga stage III–IVa invasive thymoma and 36 with stage I–IVa thymic carcinoma. Survival probabilities were estimated with the Kaplan-Meier method. Risk factors related to survival were identified by univariate and multivariate competing risk analysis, with overall survival (OS) as the competing risk. Cox regression analysis was used to identify risk factors for OS. Results Median follow-up time for all patients was 64 months. At 5/10 years, rates of OS and freedom from recurrence (FFR) were 81/58% and 81/65%, respectively. Of patients who underwent surgery, trimodality treatment produced better survival compared to less aggressive treatment among patients with stage III disease (p=0.03). Among patients who underwent trimodality treatment, patients with stage III disease had better OS (p=0.03) and FFR (p<0.001) than those with stage IVA disease. On Cox regression analysis, decreased OS was associated with thymic carcinoma (hazard ratio [HR]=7.36, 95% CI=2.38–22.77, p=0.001), R2/unresectable disease (HR=8.45, 95% CI=1.44–49.42, p=0.02) and an Eastern Cooperative Oncology Group performance score of 1 (HR=8.14, 95% CI=1.55–42.75, p=0.01) or 2–3 (HR=29.60, 95% CI=4.0–218.98, p=0.001) versus 0. Conclusion Aggressive treatment with chemotherapy, surgical resection, and postoperative radiation therapy can produce long-term survival for patients with invasive thymic malignanices.

    Objectives This study aimed to build a prediction score of prognosis for patients with advanced hepatocellular carcinoma (HCC) after sorafenib treatment. Methods A total of 165 patients with advanced HCC who were treated with sorafenib were analyzed. Readily available baseline factors were used to establish a scoring system for the prediction of survival. Results The median survival time (MST) was 14.2 months. The independent prognostic factors were C-reactive protein (CRP) <1.0 mg/dL [hazard ratio (HR) =0.51], albumin >3.5 g/dL (HR =0.55), alpha-fetoprotein <200 ng/mL (HR =0.45), and a lack of major vascular invasion (HR =0.39). Each of these factors had a score of 1, and after classifying the patients into five groups, the total scores ranged from 0 to 4. Higher scores were linked to significantly longer survival (p<0.0001). Twenty-nine patients (17.6%) with a score of 4 had a MST as long as 36.5 months, whereas MST was as short as 2.4 and 3.7 months for seven (4.2%) and 22 (13.3%) patients with scores of 0 and 1, respectively. Conclusions A novel prognostic scoring system, which includes the CRP level, has the ability to stratify the prognosis of patients with advanced stage HCC after treatment with sorafenib.

    The association of ifosfamide with cisplatin and 5-fluorouracil for the management of advanced squamous cell carcinoma of the head and neck was assessed in this trial. Ifosfamide was given initially to 12 patients in combination with standard fixed doses of cisplatin and 5-fluorouracil, at 1,000 mg/m2 daily on days 2, 3, and 4. Two patients died of neutropenia and severe infection, and the authors recruited seven more patients who were treated with a lower dose of ifosfamide, 800 mg/m2 daily on days 2, 3, and 4. One of the seven patients died of neutropenia and severe infection. Three complete remission were observed in 18 patients evaluable for efficacy. The study was closed early because of the severe toxicity profile demonstrated by this scheme and because of no clear advantage in efficacy versus cisplatin plus 5-fluorouracil combinations.

    Purpose: To evaluate the feasibility and efficacy of a hyperfractionated accelerated radiotherapy (RT) schedule combined with concomitant chemotherapy (Cx) in patients with locally advanced head-and-neck squamous cell carcinoma. Methods and Materials: Between 2004 and 2007, a total of 90 patients with locoregionally advanced head-and-neck squamous cell carcinoma underwent irradiation according to a hybrid fractionation schedule consisting of 20 fractions of 2 Gy (once daily) followed by 20 fractions of 1.6 Gy (twice daily) to a total dose of 72 Gy. Concomitant Cx (cisplatinum 100 mg/m{sup 2}) was administered at the start of Weeks 1 and 4. Treatment outcome and toxicity were retrospectively compared with a previous patient group (n = 73) treated with the same schedule, but without concomitant Cx, between 2001 and 2004. Results: The locoregional control (LRC) rate was 70% after 2 years. Two-year overall and 2-year disease-free survival rates were 74% and 60%, respectively. In comparison with the RT-only group, an improvement of 15% in both LRC (p = 0.03) and overall survival (p = 0.09) was observed. All patients were treated to full radiation dose according to protocol, although the Cx schedule had to be adjusted in 12 patients. No acute Grade 4 or 5 toxicity was seen, but incidences of Grade 3 acute mucositis (74.5% vs. 50.7%; p = 0.002) and dysphagia (82.2% vs. 47.9%; p < 0.001) were significantly higher in the chemoradiotherapy group compared with patients treated with RT alone. Conclusion: With this chemoradiotherapy regimen, excellent LRC and survival rates were achieved, with acceptable acute toxicity.

    Purpose. To evaluate the effects of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in patients with advanced pancreatic carcinoma. Methods. CTAI was performed in 17 patients with stage IV pancreatic cancer with (n = 11) or without (n = 6) liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The inferior pancreatic artery (IPA) was embolized to achieve delivery of the pancreatic blood supply through only the celiac artery. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. Treatment effects were evaluated based on the primary tumor size, liver metastasis, and survival time and factors such as tumor size, tumor location, and stage of pancreatic carcinoma; the embolized arteries were analyzed with respect to treatment effects and prognosis. Results. A catheter was fixed in the gastroduodenal artery and splenic artery in 10 and 7 patients, respectively. Complete peripancreatic arterial occlusion was successful in 10 patients. CT showed a decrease in tumor size in 6 of 17 (35%) patients and a decrease in liver metastases in 6 of 11 (55%) patients. The survival time ranged from 4 to 18 months (mean {+-} SD, 8.8 {+-} 1.5 months). Complete embolization of arteries surrounding the pancreas was achieved in 10 patients; they manifested superior treatment effects and prognoses (p < 0.05). Conclusion. In patients with advanced pancreatic cancer, long-term CTAI with systemic chemotherapy appeared to be effective not only against the primary tumor but also against liver metastases. Patients with successfully occluded peripancreatic arteries tended to survive longer.

    The work focuses on a unique medical repository of digital Uterine Cervix images ("Cervigrams") collected by the National Cancer Institute (NCI), National Institute of Health, in longitudinal multi-year studies. NCI together with the National Library of Medicine is developing a unique web-based database of the digitized cervix images to study the evolution of lesions related to cervical cancer. Tools are needed for the automated analysis of the cervigram content to support the cancer research. In recent works, a multi-stage automated system for segmenting and labeling regions of medical and anatomical interest within the cervigrams was developed. The current paper concentrates on incorporating prior-shape information in the cervix region segmentation task. In accordance with the fact that human experts mark the cervix region as circular or elliptical, two shape models (and corresponding methods) are suggested. The shape models are embedded within an active contour framework that relies on image features. Experiments indicate that incorporation of the prior shape information augments previous results.

    Esophageal cancer is aggressive and has poor prognosis. Esophageal squamous cell carcinoma (ESCC) is histologically the most prevalent type of esophageal cancer and ranked as the sixth leading cause of cancer death worldwide. In recent years, cancer has been widely regarded as genetic disease, as well as epigenetic abnormalities including DNA methylation, histone deacetylation, chromatin remodeling, gene imprinting and noncoding RNA regulation. In this review, we will provide a general overview of genes, proteins and microRNAs that are involved in the development of ESCC, which aims to enhance our understanding of molecular mechanisms implicated in ESCC development and progression.

    Abstact Background The purpose was to determine whether a brachytherapy boost improves outcomes in patients with advanced nasopharyngeal carcinoma treated with standard chemo-radiotherapy. Methods Patients with nasopharyngeal carcinoma WHO grades I-III and TNM stages III or non-metastatic stage IV were eligible for this phase III study. Patients were randomized to either arm (A) induction chemotherapy, followed by external beam radiotherapy (EBRT) with concomitant cisplatin (n = 139) or arm (B), the same schedule plus a brachytherapy boost to the nasopharynx (n = 135). The EBRT doses given were 70 Gy to the primary tumour and positive lymph nodes and 46 Gy to the negative neck. The additional brachytherapy boost in arm (B) was given by either low dose-rate (LDR – 11 Gy) or high dose-rate (HDR – 3 fractions of 3.0 Gy) brachytherapy. The primary endpoint was 3-year overall survival (OS) and secondary endpoints were: local control, regional control, distant metastasis and grade 3–4 adverse events. Results 274 patients were randomized between September 2004 and December 2008. The two arms were comparable with regard to age, gender, stage and grade. 273 patients completed treatment. Median follow-up was 29 months (0.2-67 months). The effect of treatment arm, country, age, gender, WHO pathology, stage (T3-4, N2-3 versus other) and chemotherapy on overall survival (OS), disease-free survival (DFS) and local recurrence-free survival (LRFS) was studied. Stage significantly affected OS (p = 0.024) and DFS (p = 0.018) while age significantly affected OS (p = 0.014). None of the other factors studied were significant. The 3-year LRFS was 60.5% and 54.4% in arms A and B respectively (p = 0.647). The 3-year regional control rate in the neck was 59.7% and 54.3% respectively (p = 0.7). Distant metastasis developed in 59.7% of patients in arm A and 55.4% in arm B (p = 0.377). Patients with T1/T2 N + had a 3 year LRFS of 51.8% in Arm A (62 patients) versus 57.9% in Arm B (67

    Abnormal activation of hedgehog pathway signaling is a key driver in the pathogenesis of basal cell carcinoma (BCC). Vismodegib, a first-in-class small-molecule inhibitor of hedgehog pathway signaling, is approved by regulatory authorities for the treatment of adults who have metastatic BCC or locally advanced BCC that has recurred after surgery, or who are not candidates for surgery and who are not candidates for radiation. A second inhibitor, sonidegib, was also recently approved for the same patient group with locally advanced BCC. Adverse events (AEs) commonly observed in hedgehog pathway inhibitor (HPI)-treated patients include muscle spasms, ageusia/dysgeusia, alopecia, weight loss, and asthenia (fatigue). These AEs are thought to be mechanistically related to inhibition of the hedgehog pathway in normal tissue. Although the severity of the majority of AEs associated with HPIs is grade 1–2, the long-term nature of these AEs can lead to decreased quality of life, treatment interruption, and in some cases discontinuation, all of which might affect clinical outcome. The incidence, clinical presentation, putative mechanisms, and management strategies for AEs related to HPIs in advanced BCC are described. These observations represent the first step toward the development of mechanism-based preventive and management strategies. Knowledge of these AEs will allow health care professionals to provide appropriate counseling and supportive care interventions, all of which will contribute to improved quality of life and optimal benefit from therapy. Implications for Practice: The hedgehog pathway inhibitors (HPIs) vismodegib and sonidegib represent a therapeutic breakthrough for patients with advanced basal cell carcinoma. However, the nature of the low-grade adverse events (AEs) commonly observed in HPI-treated patients, including muscle spasms, ageusia/dysgeusia, alopecia, weight loss, and fatigue, can impact clinical outcomes as a result of decreased quality of life

    Cervix-cancer is the third most common female cancer worldwide. It is the leading cancer among Indian females with more than million new diagnosed cases and 50% mortality, annually. The high mortality rates can be attributed to late diagnosis. Efficacy of Raman spectroscopy in classification of normal and pathological conditions in cervix cancers on diverse populations has already been demonstrated. Our earlier ex vivo studies have shown the feasibility of classifying normal and cancer cervix tissues as well as responders/non-responders to Concurrent chemoradiotherapy (CCRT). The present study was carried out to explore feasibility of in vivo Raman spectroscopic methods in classifying normal and cancerous conditions in Indian population. A total of 182 normal and 132 tumor in vivo Raman spectra, from 63 subjects, were recorded using a fiberoptic probe coupled HE-785 spectrometer, under clinical supervision. Spectra were acquired for 5 s and averaged over 3 times at 80 mW laser power. Spectra of normal conditions suggest strong collagenous features and abundance of non-collagenous proteins and DNA in case of tumors. Preprocessed spectra were subjected to Principal Component-Linear Discrimination Analysis (PCLDA) followed by leave-one-out-cross-validation. Classification efficiency of ~96.7% and 100% for normal and cancerous conditions respectively, were observed. Findings of the study corroborates earlier studies and suggest applicability of Raman spectroscopic methods in combination with appropriate multivariate tool for objective, noninvasive and rapid diagnosis of cervical cancers in Indian population. In view of encouraging results, extensive validation studies will be undertaken to confirm the findings.

    Purpose: To investigate the antitumor effect of resin microspheres loaded with 90-yttrium against hepatocellular carcinoma and their safety in the setting of liver cirrhosis. Patients and Methods: Data from 24 consecutive patients with hepatocellular carcinoma (HCC) treated by radioembolization in the period from September 2003 to February 2005 were reviewed. Patients received no further antineoplastic therapy. A comprehensive evaluation was performed to prevent the risk of damage due to microsphere misplacing. Patients were discharged the day after microspheres injection. Results: Serious liver toxicity observed among cirrhotic patients in a first period was subsequently prevented by modifying the selection criteria and the method for calculating the activity to be administered. Among 21 patients evaluable for response using Response Evaluation Criteria in Solid Tumors (RECIST) criteria, a reduction in size of target lesions was observed in all but 1 patient. When considering only target lesions, disease control rate and response rate were 100% and 23.8%, respectively. However, 43% of patients progressed in the liver in the form of new lesions appearing a median time of 3 months after radioembolization. Conclusion: Our experience in these series of patients indicates that radioembolization using resin microspheres has a significant antitumor effect against HCC and that using stringent selection criteria and conservative models for calculating Radiation activity to be administered, radioembolization can be performed safely even in cirrhotic patients.

    Background Sorafenib (Sor) is acknowledged as a standard therapy for advanced hepatocellular carcinoma (HCC). This trial was conducted to evaluate the effect of addition of hepatic arterial infusion chemotherapy with cisplatin (SorCDDP) to Sor for the treatment of advanced HCC. Patients and methods We conducted a multicenter open-labeled randomized phase II trial in chemo-naïve patients with advanced HCC with Child-Pugh scores of 5–7. Eligible patients were randomly assigned 2:1 to receive SorCDDP (sorafenib: 400 mg bid; cisplatin: 65 mg/m2, day 1, every 4–6 weeks) or Sor (400 mg bid). The primary end point was overall survival. Results A total of 108 patients were randomized (Sor, n = 42; SorCDDP, n = 66). The median survival in the Sor and SorCDDP arms were 8.7 and 10.6 months, respectively [stratified hazard ratio (95% confidence interval), 0.60 (0.38–0.96), P = 0.031]. The median time to progression and the response rate were, respectively, 2.8 months and 7.3% in the Sor arm and 3.1 months and 21.7% in the SorCDDP arm. The adverse events were more frequent in the SorCDDP arm than in the Sor arm, but well-tolerated. Conclusion SorCDDP yielded favorable overall survival when compared with Sor in patients with advanced HCC.

    Vismodegib is an effective treatment for advanced basal cell carcinoma (BCC), but primary resistance to vismodegib remains to be elucidated. Alternative approaches are warranted to help selecting patients most likely to be responsive to treatment. The identification of immunohistochemical markers may support this perspective, as well as better understanding of resistance mechanisms. To determine the level of expression of CD56, PDGF-R, CD117, MMP9, TIMP3, and CXCR4 in advanced BCC, and explore whether expression levels are associated with non-response to vismodegib. A cross-sectional study was conducted. Immunohistochemical markers were selected based on their roles in tumour proliferation and/or migration in skin tumours. Tissue samples included pretreatment advanced BCC samples from patients treated with vismodegib, with an available response after six months of treatment. Regression optimised models were used to build hypotheses regarding a possible association between expression levels and non-response to vismodegib, which was then tested by logistic regression. Twenty-three patients were included. The percentage of samples expressing markers ranged from 43.5% (CD117) to 91.3% (CXCR4). CD56 expression was significantly associated with an increased risk of non-response to vismodegib (OR = 5.5; CI 95%: 3.4-29.8; p = 0.0488); a similar association was suggested for CXCR4 (p = 0.066), but not identified for other markers. These results provide a better understanding of the expression of immunohistochemical markers in advanced BCC. Further detailed analysis of CD56 expression may provide insights into guiding further investigation of the correlation between this marker and non-response to vismodegib.

    Purpose To develop the treatment algorithm from multivariate survival analyses (MVA) in patients with Barcelona clinic liver cancer (BCLC) C (advanced) Hepatocellular carcinoma (HCC) patients treated with Trans-arterial Chemoembolization (TACE). Methods Consecutive unresectable and non-tranplantable patients with advanced HCC, who received DEB TACE were studied. A total of 238 patients (mean age, 62.4yrs) was included in the study. Survivals were analyzed according to different parameters from the time of the 1st DEB TACE. Kaplan Meier and Cox Proportional Hazard model were used for survival analysis. The SS was constructed from MVA and named BCLC C HCC Prognostic (BCHP) staging system (SS). Results Overall median survival (OS) was 16.2 months. In HCC patients with venous thrombosis (VT) of large vein [main portal vein (PV), right or left PV, hepatic vein, inferior vena cava] (22.7%) versus small vein (segmental/subsegmental PV) (9.7%) versus no VT had OSs of 6.4 months versus 20 months versus 22.8 months respectively (p<0.001). On MVA, the significant independent prognostic factors (PFs) of survival were CP class, eastern cooperative oncology group (ECOG) performance status (PS), single HCC<5 cm, site of VT, metastases, serum creatinine and serum alpha-feto protein. Based on these PFs, the BCHP staging system was constructed. The OSs of stages I, II and III were 28.4 months, 11.8 months and 2.4 months accordingly (p<0.001). The treatment plan was proposed according to the different stages. Conclusion On MVA of patients with advanced HCC treated with TACE, significant independent prognostic factors (PFs) of survival were CP class, ECOG PS, single HCC<5 cm or others, site of VT, metastases, serum creatinine and serum alpha-feto protein. New BCHP SS was proposed based on MVA data to identify the suitable advanced HCC patients for TACE treatments. PMID:28170405

    Sorafenib and hepatic arterial infusion chemotherapy (HAIC) are both indicated for unresectable hepatocellular carcinoma (HCC). In this study, we compared the efficacy and safety of HAIC to that of sorafenib in elderly patients with HCC. Eligible patients included those aged ≥70 years, with histologically or clinically confirmed advanced HCC. A total of 12 patients received sorafenib (800 mg per day) and 8 patients received HAIC with 5-fluorouracil (300 mg/m(2) on days 1-5 and 8-12) with or without cisplatin (20 mg/m(2) on days 1 and 8), with interferon-α (3 times per week for 4 weeks). The response rate was significantly higher in patients treated with HAIC (37.5%) compared to that in patients treated with sorafenib (no response). The median overall survival (18.6 and 11.7 months) and progression-free survival (4.0 and 5.0 months) were similar between the sorafenib and HAIC groups, respectively. In the sorafenib group, 58.3% of the patients discontinued treatment compared to none in the HAIC group. The most frequent adverse event leading to discontinuation of sorafenib was anorexia. Similar to sorafenib, HAIC appears to be a feasible treatment and may also have the advantage of an adequate safety profile for elderly patients with advanced HCC. Further study of HAIC in a larger population of elderly patients is required to assess its potential as an alternative to sorafenib for HCC.

    Many patients with nasopharyngeal carcinoma (NPC) have marked anatomic change during intensity-modulated radiation therapy (IMRT). In this study, the magnitude of anatomic changes and its dosimetric effects were quantified. Fifteen patients with locally advanced NPC treated with IMRT had repeated computed tomography (CT) after 18 fractions. A hybrid plan was made to the anatomy of the second computed tomography scan. The dose of the original plan, hybrid plan, and new plan were compared. The mean volume of left and right parotid decreased 6.19 mL and 6.44 mL, respectively. The transverse diameters of the upper bound of odontoid process, the center of odontoid process, and the center of C2 vertebral body slices contracted with the mean contraction of 8.2 mm, 9.4 mm, and 7.6 mm. Comparing the hybrid plan with the treatment plan, the coverage of target was maintained while the maximum dose to the brain stem and spinal cord increased by 0.08 to 6.51 Gy and 0.05 to 7.8 Gy. The mean dose to left and right parotid increased by 2.97 Gy and 2.57 Gy, respectively. A new plan reduced the dose of spinal cord, brain stem, and parotids. Measurable anatomic changes occurring during the IMRT for locally advanced NPC maintained the coverage of targets but increased the dose to critical organs. Those patients might benefit from replanning.

    Hepatocellular carcinoma (HCC) is one of the most intractable and lethal cancers; most cases are diagnosed at advanced stages with underlying liver dysfunction and are frequently resistant to conventional chemotherapy and radiotherapy. The development of tumor-targeting systems may improve treatment outcomes. Nanomedicine platforms are of particular interest for enhancing chemotherapeutic efficiency, and they include polymeric micelles, which enable targeting of multiple drugs to solid tumors, including imaging and therapeutic agents. This allows concurrent diagnosis, targeting strategy validation, and efficacy assessment. We used polymeric micelles containing the T1-weighted magnetic resonance imaging contrast agent gadolinium-diethylenetriaminpentaacetic acid (Gd-DTPA) and the parent complex of the anticancer drug oxaliplatin [(1,2-diaminocyclohexane)platinum(II) (DACHPt)] for simultaneous imaging and therapy in an orthotopic rat model of HCC. The Gd-DTPA/DACHPt-loaded micelles were injected into the hepatic artery, and magnetic resonance imaging performance and antitumor activity against HCC, as well as adverse drug reactions were assessed. After a single administration, the micelles achieved strong and specific tumor contrast enhancement, induced high levels of tumor apoptosis, and significantly suppressed tumor size and growth. Moreover, the micelles did not induce severe adverse reactions and significantly improved survival outcomes in comparison to oxaliplatin or saline controls. Our results suggest that Gd-DTPA/DACHPt-loaded micelles are a promising approach for effective diagnosis and treatment of advanced HCC.

    Background For patients diagnosed with locally advanced esophageal cancer, neoadjuvant therapy followed by surgery is the most common approach. However, randomized trials resulted in inconsistent conclusions. We conducted this retrospective study to evaluate the influence of neoadjuvant therapy on postoperative events and the influence on disease-free survival (DFS) and overall survival (OS). Methods We retrospectively reviewed all of the patients underwent surgery following neoadjuvant therapy for locally advanced esophageal squamous cell carcinoma (ESCC) during January 1st, 2013 and December 31st, 2015 in Fudan University Shanghai Cancer Center (FUSCC). Prognostic factors for DFS and OS were identified by univariate and multivariate analyses. Results A total of fifty patients were included. Regarding postoperative morbidities, pneumonia and leakage occurred in 9 (18.0%) and 6 (12.0%) patients, respectively. For the whole patients, the 1-, 2-, 3-year DFS and OS rates were 57.0%, 48.0%, 42.0% and 86.0%, 73.0%, 62.0%, respectively. Lung metastasis and mediastinal node involvement were the most common relapse patterns. Univariate and multivariate analyses confirmed ypTNM stage as an independent prognostic factor for both DFS and OS; while leakage was an independent prognostic factor for DFS. Conclusions Neoadjuvant therapy did not increase postoperative morbidities but did achieve favorable survival. The ypTNM stage was an independent prognostic factor for both DFS and OS. Long-term survival needs further investigation. PMID:28275480

    Sorafenib is still the only systemic drug approved for the treatment of advanced hepatocellular carcinoma (HCC). In recent years, several investigational agents mainly targeting angiogenesis failed in late-phase clinical development due to either toxicity or lack of benefit. Recently, data of the RESORCE trial, a placebo-controlled Phase III study that evaluated the efficacy and safety of regorafenib in patients with HCC and documented disease progression after systemic first-line treatment with sorafenib, were presented at the ESMO World Congress on Gastrointestinal Cancer, 2016. Regorafenib treatment resulted in a 2.8-month survival benefit compared to placebo (10.6 months vs 7.8 months). Side effects were consistent with the known profile of regorafenib. The approval of regorafenib for this indication is expected in 2017. Further candidate agents in Phase III evaluation for second-line treatment of patients with HCC are the MET inhibitors tivantinib and cabozantinib, the vascular endothelial growth factor receptor-2 antibody ramucirumab, and the programmed death receptor-1 (PD-1) blocking antibody pembrolizumab. Furthermore, results from two first-line trials with either the tyrosine kinase inhibitor lenvatinib or the PD-1 antibody nivolumabin in comparison to sorafenib are awaited in the near future and might further change the treatment sequence of advanced HCC.

    Between the years 1970 and 1986, the author managed 132 patients with T3 glottic carcinoma. Over half of these patients were explored in an effort to safely perform subtotal laryngectomy. Twenty-seven of them were found to have extension of tumor that required immediate conversion to total laryngectomy. Five-year survival rates were essentially the same for all three groups: immediate total laryngectomy, subtotal laryngectomy, and total laryngectomy following attempted subtotal laryngectomy. I conclude that carefully selected patients with T3 glottic cancer may be candidates for subtotal laryngectomy after surgical exploration, since conversion to total laryngectomy yields local control rates as satisfactory as those of initial total laryngectomy. When subtotal laryngectomy is possible, local control of tumor and recurrence rates are as satisfactory as those of total laryngectomy.

    In this work we focus on the generation of reliable ground truth data for a large medical repository of digital cervicographic images (cervigrams) collected by the National Cancer Institute (NCI). This work is part of an ongoing effort conducted by NCI together with the National Library of Medicine (NLM) at the National Institutes of Health (NIH) to develop a web-based database of the digitized cervix images in order to study the evolution of lesions related to cervical cancer. As part of this effort, NCI has gathered twenty experts to manually segment a set of 933 cervigrams into regions of medical and anatomical interest. This process yields a set of images with multi-expert segmentations. The objectives of the current work are: 1) generate multi-expert ground truth and assess the diffculty of segmenting an image, 2) analyze observer variability in the multi-expert data, and 3) utilize the multi-expert ground truth to evaluate automatic segmentation algorithms. The work is based on STAPLE (Simultaneous Truth and Performance Level Estimation), which is a well known method to generate ground truth segmentation maps from multiple experts' observations. We have analyzed both intra- and inter-expert variability within the segmentation data. We propose novel measures of "segmentation complexity" by which we can automatically identify cervigrams that were found difficult to segment by the experts, based on their inter-observer variability. Finally, the results are used to assess our own automated algorithm for cervix boundary detection.

    Background Haemoglobin levels and tissue oxygenation influence tumour outcome in carcinoma cervix radiotherapy. The clinical impact of haemoglobin levels on acute normal tissue toxicity during radiation and interaction with chemotherapy in carcinoma of the cervix is underexplored. This paper aims to explore this issue. Methods Treatment toxicity among 227 patients with squamous cell carcinoma of the cervix stages II B–IV A, receiving pelvic radiotherapy or chemoradiation at our institute, were studied prospectively. The baseline and weekly haemoglobin levels during treatment were recorded. Acute toxicities were recorded using Radiation Therapy Oncology Group (RTOG) acute toxicity and Common Terminology Criteria for Adverse Events (CTCAE) criteria, version 4. For the analysis, patients were divided into two groups, depending on nadir haemoglobin levels. A cut-off value for anaemia was selected at 12 gm/dL. Toxicity was compared between anaemic and non-anaemic groups. Results Patients on chemoradiation and having haemoglobin levels >12 gm/dL suffered significantly higher dermatitis (two-tailed p value = 0.0288) and vaginal mucositis (two-tailed p value = 0.0187) of at least RTOG acute toxicity grade 2, compared with the anaemic group. In contrast patients receiving radiotherapy alone did not experience any significantly greater mucocutaneous toxicity if haemoglobin was >12 gm/dL. Anaemia had significantly greater impact on malaise and neutropenia (two-tailed p value <0.0001) of CTCAE grade 1 and above among chemoradiation patients, as opposed to those receiving radiotherapy alone (two-tailed p values = 0.0012 for neutropenia and 0.0422 for malaise). Conclusion Haemoglobin values >12 gm/dL significantly worsen acute mucocutaneous toxicity in locally advanced cervical cancer patients receiving chemoradiation. Similar effects are not observed in the absence of chemotherapy. PMID:24963348

    Objectives: To study the effect of adding chemotherapy to radiotherapy (RT) on overall survival and event-free survival for patients with nasopharyngeal carcinoma. Methods and Materials: This meta-analysis used updated individual patient data from randomized trials comparing chemotherapy plus RT with RT alone in locally advanced nasopharyngeal carcinoma. The log-rank test, stratified by trial, was used for comparisons, and the hazard ratios of death and failure were calculated. Results: Eight trials with 1753 patients were included. One trial with a 2 x 2 design was counted twice in the analysis. The analysis included 11 comparisons using the data from 1975 patients. The median follow-up was 6 years. The pooled hazard ratio of death was 0.82 (95% confidence interval, 0.71-0.94; p = 0.006), corresponding to an absolute survival benefit of 6% at 5 years from the addition of chemotherapy (from 56% to 62%). The pooled hazard ratio of tumor failure or death was 0.76 (95% confidence interval, 0.67-0.86; p < 0.0001), corresponding to an absolute event-free survival benefit of 10% at 5 years from the addition of chemotherapy (from 42% to 52%). A significant interaction was observed between the timing of chemotherapy and overall survival (p = 0.005), explaining the heterogeneity observed in the treatment effect (p = 0.03), with the highest benefit resulting from concomitant chemotherapy. Conclusion: Chemotherapy led to a small, but significant, benefit for overall survival and event-free survival. This benefit was essentially observed when chemotherapy was administered concomitantly with RT.

    Background: Cisplatin-based combination chemotherapy is standard first-line treatment for patients with advanced urothelial carcinoma (UC). Molecular profiling studies reveal that the PI3K/AKT/mTOR pathway is altered in a significant percentage of UCs. Objective: We conducted a phase I trial to evaluate the feasibility of combining the mTOR inhibitor everolimus with gemcitabine and split-dose cisplatin (GC) in advanced UC in the first-line setting. Methods: Patients received gemcitabine 800 mg/m2 and cisplatin 35 mg/m2 on days 1 and 8 of 21-day cycles for a total of 6 cycles in combination with everolimus at increasing dose levels (DL1:5 mg QOD, DL2:5 mg daily, DL3:10 mg daily) following a standard 3+3 design. Responses were assessed every 2 cycles. Patients with at least stable disease (SD) continued everolimus until progression. Goals were to establish dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) for the combination. Results: 12 patients were enrolled, 3 at DL1, 3 at DL2, and an additional 6 at DL1 *(DL1 following de-escalation). 3/3 patients at DL2 had DLTs during cycle 1. 2/8 evaluable patients at DL1/DL1 * had DLTs during cycle 1. DLTs were primarily hematologic. Further toxicities, also primarily hematologic, were observed during later treatment cycles, leading to 8 chemotherapy dose reductions overall. Partial responses were observed in 4/10 evaluable patients, and SD in 5/10. Median overall survival was 10.8 months (95% CI 6.9, not reached). Conclusions: The maximum tolerated dose was reached at the lowest dose level, 5 mg QOD, for everolimus in combination with gemcitabine and split-dose cisplatin in advanced UC. The regimen was limited by hematologic toxicity. PMID:27376132

    Locally advanced hepatocellular carcinoma (HCC) with portal vein thrombosis carries a 1-year survival rate <10%. Localized concurrent chemoradiotherapy (CCRT), followed by hepatic arterial infusion chemotherapy (HAIC), was recently introduced in this setting. Here, we report our early experience with living donor liver transplantation (LDLT) in such patients after successful down-staging of HCC through CCRT and HAIC. Between December 2011 and September 2012, eight patients with locally advanced HCC at initial diagnosis were given CCRT, followed by HAIC, and underwent LDLT at the Severance Hospital, Seoul, Korea. CCRT [45 Gy over 5 weeks with 5-fluorouracil (5-FU) as HAIC] was followed by HAIC (5-FU/cisplatin combination every 4 weeks for 3–12 months), adjusted for tumor response. Down-staging succeeded in all eight patients, leaving no viable tumor thrombi in major vessels, although three patients first underwent hepatic resections. Due to deteriorating liver function, transplantation was the sole therapeutic option and offered a chance for cure. The 1-year disease-free survival rate was 87.5%. There were three instances of post-transplantation tumor recurrence during follow-up monitoring (median, 17 months; range, 10–22 months), but no deaths occurred. Median survival time from initial diagnosis was 33 months. Four postoperative complications recorded in three patients (anastomotic strictures: portal vein, 2; bile duct, 2) were resolved through radiologic interventions. Using an intensive tumor down-staging protocol of CCRT followed by HAIC, LDLT may be a therapeutic option for selected patients with locally advanced HCC and portal vein tumor thrombosis.

    Background To establish recurrence patterns among locally advanced head and neck non-nasopharyngeal squamous cell carcinoma (HNSCC) patients treated with radical (chemo-) radiotherapy and to correlate the sites of loco-regional recurrence with radiotherapy doses and target volumes Method 151 locally advanced HNSCC patients were treated between 2004-2005 using radical three-dimensional conformal radiotherapy. Patients with prior surgery to the primary tumour site were excluded. The sites of locoregional relapses were correlated with radiotherapy plans by the radiologist and a planning dosimetrist. Results Median age was 59 years (range:34-89). 35 patients had stage III disease, 116 patients had stage IV A/B. 36 patients were treated with radiotherapy alone, 42 with induction chemotherapy, 63 with induction and concomitant chemoradiotherapy and 10 concomitant chemoradiotherapy. Median follow-up was 38 months (range 3-62). 3-year cause specific survival was 66.8%. 125 of 151 (82.8%) achieved a complete response to treatment. Amongst these 125 there were 20 local-regional recurrence, comprising 8 local, 5 regional and 7 simultaneous local and regional; synchronous distant metastases occurred in 7 of the 20. 9 patients developed distant metastases in the absence of locoregional failure. For the 14 local recurrences with planning data available, 12 were in-field, 1 was marginal, and 1 was out-of-field. Of the 11 regional failures with planning data available, 7 were in-field, 1 was marginal and 3 were out-of-field recurrences. Conclusion The majority of failures following non-surgical treatment for locally advanced HNSCC were loco-regional, within the radiotherapy target volume. Improving locoregional control remains a high priority. PMID:21609453

    Hepatitis B is leading cause of liver related morbidity in Asia with predominant genotypes B and C in East-Asia. Data on Serum, intrahepatic viral-markers, and long-term follow-up of prevalent genotypes (GT) B and C in patients with biopsy proven advanced fibrosis are sparse. To compare serum, intrahepatic viral-markers and development of hepatocellular carcinoma (HCC) in GT-B and C in patients with advanced fibrosis (Ishak ≥ 4). Sixty-three treatment-naïve patients identified with advanced fibrosis on liver-biopsy performed between 1998 and 2000 at Singapore General Hospital. FFPE tissue was available for 59 patients and serum for 42 patients. HBV-DNA was quantified in serum and liver while qHBsAg quantified in serum. Patients were followed-up till December 2015. The median age was 47 ± 16 years, with 77.7% males. About 19 were GT-B, 43 patients were GT-C, and 1 had both GT-B and C. Mean follow-up was 13.5 years. The median serum HBV-DNA was 6.25 ± 2.17 and 6.58 ± 1.85 log IU/ml, serum HBsAg was 3.29 ± 0.80 and 3.45 ± 1.85 log IU/ml, and intrahepatic HBV-DNA was 0.52 ± 3.73 copies/cell and 0.4 ± 1.37 copies/cell in the GT-B and C, respectively (P > 0.1 in all). Complete cirrhosis (Ishak-6) was present in 47.6%, Ishak-5 fibrosis in 33.3%, and Ishak-4 fibrosis in 19% at recruitment. On follow-up HCC developed in 8/43 in GT-C and in 3/19 GT-B (P = 0.86). Advanced age and cirrhosis were significant factors for development of HCC. No difference in serum HBV-DNA, qHBsAg or intrahepatic HBV-DNA was seen in the two genotypes. HCC development seen over long-term follow-up was independent of genotypes in patients with advanced fibrosis. J. Med. Virol. 89:845-848, 2017. © 2016 Wiley Periodicals, Inc.

Methods Patients in the HALT-C Trial were tested every 3 months for 42 months. Screening ultrasound was performed every 12 months. Levels of biomarkers were compared in patients in whom HCC did or did not develop. Results 855 patients were evaluated; HCC developed in 46. Among patients without HCC, 73.2% had AFP consistently <20, 24.5% had at least one AFP between 20-199, while 2.3% had at least one AFP value ≥200 ng/mL; 73.7% had DCP consistently <90, 11.6% had at least one DCP between 90-149, and 14.7% had at least one DCP value ≥150 mAU/mL. AFP-L3 ≥10% was present at least once in 9.0% and in 17.1% of those with AFP >20 ng/mL. Among all patients with elevated biomarkers, a diagnosis of HCC was made in 0-31.6% (depending on the biomarker and cutoff) during the subsequent 24 months. AFP ≥200 ng/mL had the highest specificity (99%), but sensitivity was ≤20%. DCP ≥40 mAU/mL had the highest sensitivity (76%), but specificity was ≤58%. Independent predictors of elevated AFP were gender (female), race (Black), more advanced disease, and HCC. Elevated DCP was associated with more advanced disease and HCC. Conclusions Mild-moderate elevations in total AFP and DCP but not AFP-L3 occur frequently in patients with chronic hepatitis C and advanced fibrosis, are related to factors other than HCC, and are poor predictors of HCC.

    Objective Human epididymis protein 4 (HE4) is a promising biomarker of epithelial ovarian cancer (EOC). But its role in assessing the primary optimal debulking (OD) of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma. Methods We reviewed the records of 90 patients with advanced ovarian, tubal or peritoneal carcinoma who underwent primary cytoreduction at the Department of Obstetrics and Gynecology of Peking University People’s Hospital between November 2005 and October 2010. Preoperative serum HE4 and CA125 levels were detected with EIA kit. A receiver operating characteristic (ROC) curve was used to determine the most useful HE4 cut-off value. Logistic regression analysis was performed to identify significant preoperative clinical characteristics to predict optimal primary cytoreduction. Results OD was achieved in 47.7% (43/48) of patients. The median preoperative HE4 level for patients with OD vs. suboptimal debulking was 423 and 820 pmol/L, respectively (P<0.001). The areas under the ROC curve for HE4 and CA125 were 0.716 and 0.599, respectively (P=0.080). The most useful HE4 cut-off value was 473 pmol/L. Suboptimal cytoreduction was obtained in 66.7% (38/57) of cases with HE4 ≥473 pmol/L compared with only 27.3% (9/33) of cases with HE4 <473 pmol/L. At this threshold, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for diagnosing suboptimal debulking were 81%, 56%, 67%, and 73%, respectively. Logistic regression analysis showed that the patients with HE4 ≥473 pmol/L were less likely to achieve OD (odds ratio =5.044, P=0.002). Conclusions Preoperative serum HE4 may be helpful to predict whether optimal cytoreductive surgery could be obtained or whether extended cytoreduction would be needed by an interdisciplinary team.

    Radiation therapy for squamous cell carcinoma of the oral cavity may be curative, but carries a risk of permanent damage to bone, salivary glands, and other soft tissues. We studied the potential of intensity modulated radiotherapy (IMRT) to improve target volume coverage, and normal tissue sparing for advanced oral cavity carcinoma (OCC). Six patients with advanced OCC requiring bilateral irradiation to the oral cavity and neck were studied. Standard 3D conformal radiotherapy (3DCRT) and inverse-planned IMRT dose distributions were compared by using dose-volume histograms. Doses to organs at risk, including spinal cord, parotid glands, and mandible, were assessed as surrogates of radiation toxicity. PTV1 mean dose was 60.8 {+-} 0.8 Gy for 3DCRT and 59.8 {+-} 0.1 Gy for IMRT (p = 0.04). PTV1 dose range was 24.7 {+-} 6 Gy for 3DCRT and 15.3 {+-} 4 Gy for IMRT (p = 0.001). PTV2 mean dose was 54.5 {+-} 0.8 Gy for 3DCRT and for IMRT was 54.2 {+-} 0.2 Gy (p = 0.34). PTV2 dose range was improved by IMRT (7.8 {+-} 3.2 Gy vs. 30.7 {+-} 12.8 Gy, p = 0.006). Homogeneity index (HI) values for PTV2 were closer to unity using IMRT (p = 0.0003). Mean parotid doses were 25.6 {+-} 2.7 Gy for IMRT and 42.0 {+-} 8.8 Gy with 3DCRT (p = 0.002). The parotid V30 in all IMRT plans was <45%. The mandible V50, V55, and V60 were significantly lower for the IMRT plans. Maximum spinal cord and brain stem doses were similar for the 2 techniques. IMRT provided superior target volume dose homogeneity and sparing of organs at risk. The magnitude of reductions in dose to the salivary glands and mandible are likely to translate into reduced incidence of xerostomia and osteoradionecrosis for patients with OCC.

    Purpose: To evaluate the efficacy and toxicity of accelerated radiotherapy with concurrent chemotherapy in advanced head-and-neck squamous cell carcinoma. Methods and Materials: Between April 2003 and May 2008, 43 consecutive patients with advanced head-and-neck squamous cell carcinoma received accelerated chemoradiation with concurrent cisplatin or cetuximab. The doses for intensity-modulated radiotherapy with simultaneous integrated boost were 67.5, 60.0, and 54 Gy in 30 daily fractions of 2.25, 2.0, and 1.8 Gy to the planning target volumes for gross disease, high-risk nodes, and low-risk nodes, respectively. Results: Of the patients, 90.7% completed chemoradiotherapy as prescribed. The median treatment duration was 43 days (range, 38-55 days). The complete response rate was 74.4%. With median follow-up of 36.7 months (range, 16.8-78.1 months) in living patients, the estimated 1-, 2-, and 5-year locoregional control, overall survival, and disease-free survival rates were 82%, 82%, and 82%; 73%, 65%, and 61%; and 73%, 73%, and 70%, respectively. One treatment-related death occurred from renal failure. Grade 3 mucositis and dermatitis occurred in 13 patients (30.2%) and 3 patients (6.9%), respectively. Grade 2 xerostomia occurred in 12 patients (27.9%). In patients with adequate follow-up, 82% were feeding tube free by 6 months after therapy; 13% remained feeding tube dependent at 1 year. Grade 3 soft-tissue fibrosis, esophageal stricture, osteoradionecrosis, and trismus occurred in 3 patients (6.9%), 5 patients (11.6%), 1 patient (2.3%), and 3 patients (6.9%), respectively. Conclusions: Our results show that intensity-modulated radiotherapy with simultaneous integrated boost with concurrent chemotherapy improved local and regional control. Acute and late toxicities were tolerable and acceptable. A prospective trial of this fractionation regimen is necessary for further assessment of its efficacy and toxicity compared with other approaches.

    The oncogenic PIM1 kinase has been implicated as a cofactor for c-MYC in prostate carcinogenesis. Here we show that in human prostate tumors, coexpression of c-MYC and PIM1 is associated with higher Gleason grades. Using a tissue recombination model coupled with lentiviral-mediated gene transfer we find that Pim1 is weakly oncogenic in naïve adult mouse prostatic epithelium. However, it cooperates dramatically with c-MYC to induce prostate cancer within 6-weeks. Importantly, c-MYC/Pim1 synergy is critically dependent on Pim1 kinase activity. c-MYC/Pim1 tumors showed increased levels of the active serine-62 (S62) phosphorylated form of c-MYC. Grafts expressing a phosphomimetic c-MYCS62D mutant had higher rates of proliferation than grafts expressing wild type c-MYC but did not form tumors like c-MYC/Pim1 grafts, indicating that Pim1 cooperativity with c-MYC in vivo involves additional mechanisms other than enhancement of c-MYC activity by S62 phosphorylation. c-MYC/Pim1-induced prostate carcinomas demonstrate evidence of neuroendocrine (NE) differentiation. Additional studies, including the identification of tumor cells coexpressing androgen receptor and NE cell markers synaptophysin and Ascl1 suggested that NE tumors arose from adenocarcinoma cells through transdifferentiation. These results directly demonstrate functional cooperativity between c-MYC and PIM1 in prostate tumorigenesis in vivo and support efforts for targeting PIM1 in prostate cancer. PMID:20140016

    Renal cell carcinoma (RCC) accounts for approximately 90%-95% of kidney tumors. With the widespread use of cross-sectional imaging modalities, more than half of RCCs are detected incidentally, often diagnosed at an early stage. This may allow the planning of more conservative treatment strategies. Computed tomography (CT) is considered the examination of choice for the detection and staging of RCC. Multidetector CT (MDCT) with the improvement of spatial resolution and the ability to obtain multiphase imaging, multiplanar and three-dimensional reconstructions in any desired plane brought about further improvement in the evaluation of RCC. Differentiation of RCC from benign renal tumors based on MDCT features is improved. Tumor enhancement characteristics on MDCT have been found closely to correlate with the histologic subtype of RCC, the nuclear grade and the cytogenetic characteristics of clear cell RCC. Important information, including tumor size, localization, and organ involvement, presence and extent of venous thrombus, possible invasion of adjacent organs or lymph nodes, and presence of distant metastases are provided by MDCT examination. The preoperative evaluation of patients with RCC was improved by depicting the presence or absence of renal pseudocapsule and by assessing the possible neoplastic infiltration of the perirenal fat tissue and/or renal sinus fat compartment.

    Renal cell carcinoma (RCC) is considered an immunogenic tumor with a prominent dysfunctional immune cell infiltrate, unable to control tumor growth. Cytokine-based immunotherapies, including interferon-α and interleukin-2, have been used for the treatment of metastatic RCC (mRCC). Long-term responses and complete remissions were observed, but durable clinical benefit efficacy in the overall population was limited and associated with significant toxicity. As a consequence, new generation agents targeting the vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTOR) pathways replaced interferon alpha (IFN-α). Strategies of tumor immune evasion include T-cell suppression by negative signals deriving from the interaction between programmed death-1 (PD-1) on the T cell and its ligand (PDL-1) on the tumor cells. Nivolumab, a programmed death 1 checkpoint inhibitor, blocks this pathway, thus reversing T-cell suppression and activating antitumor responses. The aim of this review is to summarize the safety and efficacy data of nivolumab in mRCC. Objective responses and safety profile of single-agent nivolumab are favorable in both previously treated and treatment-naïve mRCC patients. Despite toxic effects, combination therapies with nivolumab have shown promising results, indicating a potential role in the treatment of mRCC. Tailoring immunotherapy on a patient-to-patient basis represents a major challenge for the future. PMID:27695530

    Oral cancer refers to malignancies that have higher morbidity and mortality rates due to the late stage diagnosis and no early detection of a reliable diagnostic marker, while oral squamous cell carcinoma (OSCC) is amongst the world’s top ten most common cancers. Diagnosis of cancer requires highly sensitive and specific diagnostic tools which can support untraceable hidden sites of OSCC, yet to be unleashed, for which plenty of biomarkers are identified; the most recommended biomarker detection medium for OSCC includes biological fluids, such as blood and saliva. Saliva holds a promising future in the search for new clinical biomarkers that are easily accessible, less complex, accurate, and cost effective as well as being a non-invasive technique to follow, by analysing the malignant cells’ molecular pathology obtained from saliva through proteomic, genomic and transcriptomic approaches. However, protein biomarkers provide an immense potential for developing novel marker-based assays for oral cancer, hence this current review offers an overall focus on the discovery of a panel of candidates as salivary protein biomarkers, as well as the proteomic tools used for their identification and their significance in early oral cancer detection.

    The lectin binding capacity of the exfoliated epithelial cells of the uterine cervix was investigated with a modified concanavalin A - horse radish peroxidase labelling procedure. The normal healthy females exhibited a distinct rise in the percentage of labelled cells in comparison to those bearing squamous cell carcinoma. In the treated group, the responsive patients again exhibited a higher labelling percentage than the non-responsive patients - showing that the method is of both diagnostic and prognostic significance.

    As a component of the MRN (MRE11/RAD50/NBS1) complex, NBS1 plays an important role in cellular response to DNA damage and the maintenance of chromosomal integrity. The NBS1 E185Q polymorphism (8360G>C, rs1805794) has been frequently studied in some cancers with discordant results, but its association with nasopharyngeal carcinoma (NPC) in Chinese population has not been investigated. Moreover, there is no report about the association between NBS1 3'UTR variant rs2735383 and the risk of NPC. A multiple center case-control analysis was performed to assess the association between NBS1 polymorphisms and NPC risk in Eastern and Southern Chinese population. The genotypes and haplotypes were determined in 1052 cases and 1168 controls and the associations with risk of NPC were estimated by logistic regression. Cell migration assays were performed in 24-well transwell chambers to detect the effects of NBS1 E185Q SNP on cell migration. We observed significant difference in genotype frequencies at the rs1805794 C/G site between cases and controls (P(trend) < 0.0001). The C allele increases the risk for invasive disease or metastatic disease, compared with G allele. More over, CNE-2 cells (NPC cell line) transfected with pcDNA-NBS1-185Q (8360CC) had significantly higher migration levels than those transfected with pcDNA-NBS1-185E (8360GG) (P = 0.024). These findings suggest that E185Q polymorphism in NBS1 may be a genetic modifier for the occurrence and aggression of NPC.

    Purpose: To investigate whether single nucleotide polymorphisms (SNPs) in the ataxia telangiectasia mutated (ATM) gene are associated with survival in patients with esophageal squamous cell carcinoma (ESCC) receiving radiation therapy or chemoradiation therapy or surgery only. Methods and Materials: Four tagSNPs of ATM were genotyped in 412 individuals with clinical stage III or IV ESCC receiving radiation therapy or chemoradiation therapy, and in 388 individuals with stage I, II, or III ESCC treated with surgery only. Overall survival time of ESCC among different genotypes was estimated by Kaplan-Meier plot, and the significance was examined by log-rank test. The hazard ratios (HRs) and 95% confidence intervals (CIs) for death from ESCC among different genotypes were computed by a Cox proportional regression model. Results: We found 2 SNPs, rs664143 and rs664677, associated with survival time of ESCC patients receiving radiation therapy. Individuals with the rs664143A allele had poorer median survival time compared with the rs664143G allele (14.0 vs 20.0 months), with the HR for death being 1.45 (95% CI 1.12-1.89). Individuals with the rs664677C allele also had worse median survival time than those with the rs664677T allele (14.0 vs 23.5 months), with the HR of 1.57 (95% CI 1.18-2.08). Stratified analysis showed that these associations were present in both stage III and IV cancer and different radiation therapy techniques. Significant associations were also found between the SNPs and locosregional progression or progression-free survival. No association between these SNPs and survival time was detected in ESCC patients treated with surgery only. Conclusion: These results suggest that the ATM polymorphisms might serve as independent biomarkers for predicting prognosis in ESCC patients receiving radiation therapy.

    A clearcut definition of the transition from the cervix to the lower uterine segment is lacking. We therefore evaluated the location of the anatomic border between the cervix and the uterine corpus. Using both morphometry and immunohistochemisty, we examined the epithelial and stromal cell types in this transition zone. In 26 patients, longitudinal sections from the cervix uteri up to the fundus uteri were paraffin embedded and immunohistochemically stained for BCL2, keratin 5, Ki-67, CD10, and CD34. Examination of the slides resulted in the identification of a junctional zone in the cranial portion of the cervix, which is characterized by a usually abrupt morphologic and immunohistochemical transition from an endocervical-type mucinous epithelium to a ciliated tubal-like epithelium and a slow transition in stromal marker expression patterns. This epithelial transition was characterized by its intense keratin 5 and BCL2 staining with accompanying Ki-67 expression in the tubal-like epithelium, whereas the endocervical epithelium was largely negative for these markers. CD10 expression was usually quite intense directly around endocervical invaginations, but the remaining stroma was negative. Toward the endometrial cavity, expression increased and endometrial stroma displayed full thickness expression for CD10. CD34 showed a reverse pattern to CD10, with moderate expression in the endocervical stroma, which disappeared in the endometrial stoma. The immunohistochemical identification of this transition may allow a more objective determination of the extension of endometrial carcinoma into the cervix in cases that are morphologically problematic. Furthermore, as ciliated tubal-like epithelium is invariably found cranial to the uterine-cervix-isthmus junction, a diagnosis of tubal metaplasia should not be made in this region and tubal-like epithelium is not indicative of a metaplastic process.

    The administration of pre-operative chemotherapy with S-1 and concurrent radiotherapy at a total dose of 30 Gy was clinicopathologically evaluated as a treatment for locally advanced oral squamous cell carcinoma (OSCC) in the present study. The participants comprised 81 patients with OSCC, consisting of 29 patients with stage II disease, 12 patients with stage III disease and 40 patients with stage IV disease. All patients received a total radiation dose of 30 Gy in daily fractions of 2 Gy, 5 times a week, for 3 weeks, and the patients were concurrently administered S-1 at a dose of 80–120 mg, twice daily, over 4 consecutive weeks. Radical surgery was performed in all cases at 2–6 weeks subsequent to the end of pre-operative chemoradiotherapy. The most common adverse event was oropharyngeal mucositis, but this was transient in all patients. No severe hematological or non-hematological toxicities were observed. The clinical and histopathological response rates were 70.4 and 75.3%, respectively. Post-operatively, local failure developed in 6 patients (7.4%) and neck failure developed in 2 patients (2.5%). Distant metastases were found in 7 patients (8.6%). The overall survival rate, disease-specific survival rate and locoregional control rate at 5 years were 87.7, 89.9 and 90.6%, respectively. Locoregional recurrence occurred more frequently in patients that demonstrated a poor histopathological response compared with patients that demonstrated a good response (P<0.01). These results indicate that pre-operative S-1 chemotherapy with radiotherapy at a total dose of 30 Gy is feasible and effective for patients with locally advanced OSCC, and that little or no histopathological response may be a risk factor for locoregional recurrence in this treatment.

    Background The current head and neck squamous cell carcinoma (HNSCC) staging system may not capture the full prognostic implications of regional lymph node involvement. We sought to investigate the impact of level of lymph node metastasis (LNM) on survival Methods The Surveillance, Epidemiology, and End Results (SEER) registry was queried for oral cavity (OC), oropharynx (OP), larynx (LAR), and hypopharynx (HP) HNSCC. Multivariate Cox proportional hazards model was used to evaluate whether level of LNM is an independent prognostic factor. Site-specific recursive-partitioning analysis (RPA) was performed to classify patients into different risk groups. Results Totally, 14,499 patients including OC (N=2,463), OP (N=8,567), LAR (N=2,332) and HP (N=1,137) were analyzed. Both AJCC N classification and level of LNM showed significant effects on overall survival (OS) in patients with OC, OP or LAR, but not in HP. In patients with N2 disease, AJCC subclassification (N2a, N2b, N2c) was significantly associated with OS of patients with OP and LAR, but not OC or HP, while level of LNM (primary, secondary, and tertiary) was significantly associated with OS in patients with OC, OP and LAR, but not HP. Using RPA, we designed a simple, primary site-specific prognostic tool integrating AJCC T classification, N classification, and level of LNM that can be easily utilized by health care providers in clinic. Conclusions Level of LNM is an independent prognostic factor for patients with locally advanced HNSCC and could add to the prognostic value of AJCC T and N classification in patients with locally advanced HNSCC.

    Accurate tumor staging including involvement of laryngeal cartilage is important to treatment planning. Clinicians rely on imaging findings and determine initial laryngectomy for T4-stage cancer with functionless larynx or extralaryngeal spread (ELS). We examined the accuracy and prognostic value of preoperative CT findings for tumor staging in patients with locally advanced laryngeal and hypopharyngeal cancer. Ninety-four consecutive patients with clinically T3-T4-stage squamous cell carcinoma of the larynx or hypopharynx who underwent curative resection of primary tumor were reviewed. Preoperative CT findings were interpreted by a radiologist without pathologic information. Pathologic findings were used as the gold standard for correlating radiographic findings. CT imaging identified 23 (72%) of 32 cases of pathologically documented thyroid cartilage penetration and 24 (73%) of 33 cases of pathologically documented ELS. The positive predictive values for thyroid cartilage penetration and ELS were 70 and 80%, respectively. Pretreatment CT imaging up-staged 6 of 46 pT3 cases and all of 8 pT2 cases, while it down-staged 7 of 40 pT4 cases. The accuracy for clinical staging by CT imaging was 78%. Subglottic extension of the CT image was an independent variable for predicting thyroid cartilage penetration and ELS (P = 0.014). Thyroid cartilage penetration with or without ELS on CT scans is significantly associated with unfavorable DFS outcome of patients (P = 0.020). CT imaging is suboptimal in diagnosing TCP or ELS of advanced laryngeal cancer, but may be useful to predict patient survival by identifying clinically TCP.

    To investigate the effectiveness of monoclonal antibody ((131)I-chTNT) and radiofrequency ablation (RFA) combination therapy in treating middle-advanced stage hepatocellular carcinoma (HCC). Thirty-four patients diagnosed with HCC patients, divided into two groups comprised of 22 and 12 cases were included in this retrospective study. The two groups received RFA with or without ((131)I-chTNT) therapy, respectively. The patients in these groups were followed up for a median of 31 and 35 months, respectively. Patient survival was evaluated using Kaplan-Meier method and safety profiles were determined by analyzing liver, thyroid, and bone marrow toxicities. This retrospective study showed that survival time of the patients who received combination therapy was significantly longer than that of the RFA group (P = 0.052). The median progress-free survival of patients in the two groups was 23 and 7 months, respectively, and the difference was significant (P = 0.04). Tumor recurred in 3.5-8.7 months in four of the combination group patients, among which three had newly developed lesions. The red blood cells and platelets counts were not altered on day 7 and 1 month of the treatment, however, number of white blood cells was significantly increased on day 7 which was reversed back to the normal range in 2 weeks. The ALT and AST were also not significantly altered on day 7 and 1 month of therapy. In middle-advanced stage HCC patients, the combination of (131)I-chTNT and RFA therapy was found to be significantly more effective than the RFA treatment alone as assessed in short-term follow-up. However, the dose we used was insufficient to completely block the local recurrence of the lesions with a diameter of 5 cm or larger.

    Surgery and radiotherapy are the standard treatment options for patients with squamous cell carcinoma of the head and neck (SCCHN). Chemoradiotherapy is an alternative for patients with locally advanced disease. In recurrent/metastatic disease and after progression to platin-based regimens, no standard treatments other than best supportive care are currently available. Most SCCHN tumours overexpress the epidermal growth factor receptor (EGFR). This receptor is a tyrosine-kinase membrane receptor that has been implicated in angiogenesis, tumour progression and resistance to different cancer treatments. In this review, we analysed the different drugs and pathways under development to treat SCCHN, especially recurrent/metastatic disease. Until now, the EGFR signalling pathway has been considered the most important target with respect to new drugs; however, new drugs, such as immunotherapies, are currently under study. As new treatments for SCCHN are developed, the influence of therapies with respect to overall survival, progression free survival and quality of life in patients with this disease is changing.

    The role of circulating tumour cells (CTCs) in advanced oesophageal cancer (EC) patients undergoing concurrent chemoradiotherapy (CCRT) remains uncertain. A negative selection protocol plus flow cytometry was validated to efficiently identify CTCs. The CTC number was calculated and analysed for survival impact. The protocol’s efficacy in CTC identification was validated with a recovery rate of 44.6 ± 9.1% and a coefficient of variation of 20.4%. Fifty-seven patients and 20 healthy donors were enrolled. Initial staging, first response to CRT, and surgery after CRT were prognostic for overall survival, with P values of <0.0001, <0.0001, and <0.0001, respectively. The CTC number of EC patients is significantly higher (P = 0.04) than that of healthy donors. Multivariate analysis for disease-specific progression-free survival showed that surgery after response to CCRT, initial stage, and CTC number (≥21.0 cells/mL) played independent prognostic roles. For overall survival, surgery after CCRT, performance status, initial stage, and CTC number were significant independent prognostic factors. In conclusion, a negative selection plus flow cytometry protocol efficiently detected CTCs. The CTC number before CCRT was an independent prognostic factor in patients with unresectable oesophageal squamous cell carcinoma. Further large-scale prospective studies for validation are warranted. PMID:27530152

    The present study aimed to define high-risk patients who may benefit from additional adjuvant chemotherapy (AC) after concurrent chemotherapy in combination with intensity-modulated radiotherapy among patients with loco-regionally advanced nasopharyngeal carcinoma (NPC). A cohort of 511 NPC patients who received concomitant chemoradiotherapy (CCRT) with or without AC between January 2007 and December 2012 were retrospectively analysed. One hundred seventy-seven patients received CCRT alone, whereas 334 received CCRT + AC. The survival analysis showed that ages >45 years old, T3-T4 stages, N2-N3 disease and serum albumin levels ≤42 g/L were significant independent prognostic factors for overall survival (OS). Using these four risk factors, a prognostic model for OS was created as follows: (1) low-risk group: 0–1 risk factors; and (2) high-risk group: 2–4 risk factors. In the CCRT alone and CCRT + AC groups, significant differences in survival were found between the high- and low-risk groups. Patients in the high-risk group exhibited improved OS due to the addition of AC to CCRT, but no survival benefits were found in the low-risk group. In conclusion, high-risk patients may benefit from the addition of AC to CCRT regarding OS. PMID:28150694

    Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. The main etiologies of HCC are hepatitis B virus and hepatitis C virus (HCV), and non-hepatitis B/non-hepatitis C HCC (NBNC-HCC) has also been identified as an etiological factor. Although the incidence of HCV-related HCC in Japan has decreased slightly in recent years, that of NBNC-HCC has increased. The onset mechanism of NBNC-HCC, which has various etiologies, remains unclear; however, nonalcoholic steatohepatitis (NASH), a severe form of nonalcoholic fatty liver disease, is known to be an important risk factor for NBNC-HCC. Among the different advanced glycation end-products (AGEs) formed by the Maillard reaction, glyceraldehyde-derived AGEs, the predominant components of toxic AGEs (TAGE), have been associated with NASH and NBNC-HCC, including NASH-related HCC. Furthermore, the expression of the receptor for AGEs (RAGE) has been correlated with the malignant progression of HCC. Therefore, TAGE induce oxidative stress by binding with RAGE may, in turn, lead to adverse effects, such as fibrosis and malignant transformation, in hepatic stellate cells and tumor cells during NASH or NASH-related HCC progression. The aim of this review was to examine the contribution of the TAGE-RAGE axis in NASH-related HCC. PMID:26483867

    Recent clinical studies have suggested that the combination of subcutaneous recombinant human interleukin 2 (rIL-2) and interferon alpha (rIFN-alpha) is especially promising in advanced renal cell carcinoma. We assessed the safety, activity and toxicity of home therapy with these two agents in 50 patients. Each treatment cycle consisted of a 2 day pulse phase, with 9 x 10(6) IU m-2 of rIL-2 being given subcutaneously every 12 h, followed by a 6 week maintenance phase during which rIL-2 1.8 x 10(6) IU m-2 was administered subcutaneously every 12 h on days 1-5 and rIFN-alpha 2b 5 x 10(6) IU m-2 once a day on days 1, 3 and 5. Objective responses (CR+PR) occurred in 9/50 (18%) patients, six of whom (12%) achieved a complete response. Disease stabilisation was observed in 17 cases (34%) and 18 patients progressed during therapy. In the other six cases, treatment was interrupted early for toxicity or patient refusal. One patient died of myocardial infarction during the second cycle. The overall median survival was 12 months. Home therapy with subcutaneous rIL-2 + rIFN-alpha 2b proved to be active, feasible and moderately toxic, but serious adverse events can sometimes occur. PMID:8519672

    Objectives The objective of the current review was to assess published data on the role of Positron Emission Tomography (PET) for evaluation of nodal residual disease after definitive chemoradiotherapy for head and neck squamous cell carcinoma (HNSCC). Methods Studies were identified by searching PubMed electronic databases. Only studies using a post-chemoradiotherapy PET for nodal residual disease evaluation were included in the present review. Both prospective and retrospective studies were included. Information regarding sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of PET for detecting nodal residual disease after definitive chemoradiotherapy for HNSCC was extracted and analyzed. Results Twenty published studies were included in the present review. Existing data suggest that a negative post-chemoradiotherapy PET scan is associated with a negative predictive value up to 100%. The sensitivity of PET in detecting nodal residual disease is greater for scans performed ≥ 10 weeks after definitive treatment with chemoradiotherapy for HNSCC. Conclusions Further studies are needed to quantify the reliability of PET in detecting nodal residual disease after chemoradiotherapy for locoregionally advanced HNSCC. The optimal timing of PET imaging after chemoradiotherapy remains to be defined. PMID:21864252

    Preclinical models have shown that TAC-101 (4-[3,5-bis(trimethylsilyl) benzamide] benzoic acid), an oral synthetic retinoid, has antitumor activity in hepatocellular carcinoma (HCC). We conducted a phase I study in Japanese patients with advanced HCC to examine the pharmacokinetics, recommended dose, safety, and efficacy of TAC-101. The administered dose of TAC-101 was 10 mg/day in four patients (level 1), 20 mg/day in six (level 2), and 30 mg/day in three (level 3). There was no dose-limiting toxicity at level 1. Only one patient each had dose-limiting toxicity at level 2 (grade 2 fatigue, recovery requiring eight or more consecutive days of rest) and at level 3 (grade 3 splenic vein thrombosis). Level 3 (30 mg/day) was considered the maximum tolerated dose and 20 mg/day the recommended dose by a panel of medical experts, placing maximum emphasis on safety. The most frequent adverse events were fatigue, headache, and dermal symptoms such as rash. Pharmacokinetic parameters in Japanese patients with HCC were similar to those in patients in the United States, most of whom were Caucasian. Although no patient had a complete or partial response, the disease control rate was 38.5%. In conclusion, the recommended dose of TAC-101 for patients with HCC is 20 mg/day. TAC-101 had an acceptable toxicity profile, warranting further evaluation in clinical trials.

    Twenty-seven advanced ovarian carcinoma patients who had received six courses of cyclophosphamide/cisplatin and had either microscopic disease (15 patients) or no pathologically detectable disease (12 patients) after second-look laparotomy were treated with abdominopelvic radiation (2250 cGy to the abdomen and pelvis and a 2250-cGy pelvic boost). Acute myelosuppression or gastrointestinal toxicity prevented completion of treatment in only three patients. However, bowel obstruction occurred in 13 (48%), ten of whom required surgery. Five of these ten had recurrent tumor, but the other five did not. Subsequently two of the latter five did develop a recurrence, one in the lung and one in the liver. A third patient died as an indirect result of radiation damage to the bowel. Median follow-up duration is 17 months from completion of radiation. So far, 13 (48%) have developed progressive disease: four (33%) of the 12 who had a negative second-look laparotomy and nine (60%) of the 15 who had microscopic disease before radiation. While acute toxicity is tolerable, the incidence of serious chronic bowel toxicity is high. Efforts should be made to alter this therapy in order to decrease the frequency of long-term morbidity.

    It is broadly accepted that genetically engineered animal models do not always recapitulate human pathobiology. Therefore identifying best-fit mouse models of human cancers that truly reflect the corresponding human disease is of vital importance in elucidating molecular mechanisms of tumorigenesis and developing preventive and therapeutic approaches. A new hepatocellular carcinoma (HCC) mouse model lacking a novel putative tumor suppressor IQGAP2 has been generated by our laboratory. The aim of this study was to obtain the molecular signature of Iqgap2−/− HCC tumors and establish the relevance of this model to human disease. Here we report a comprehensive transcriptome analysis of Iqgap2−/− livers and a cross-species comparison of human and Iqgap2−/− HCC tumors using Significance Analysis of Microarray (SAM) and unsupervised hierarchical clustering analysis. We identified the Wnt/β-catenin signaling pathway as the top canonical pathway dysregulated in Iqgap2−/− livers. We also demonstrated that Iqgap2−/− hepatic tumors shared genetic signatures with HCC tumors from patients with advanced disease as evidenced by a 78% mouse-to-human microarray data set concordance rate with 117 out of 151 identified ortholog genes having similar expression profiles across the two species. Collectively, these results indicate that the Iqgap2 knockout mouse model closely recapitulates human HCC at the molecular level and supports its further application for the study of this disease.

    Background. To determine the prognostic significance of pretreatment levels of circulating lymphocyte (CLC), neutrophil (CNC), and monocyte (CMC) counts in patients with locally advanced cervical carcinoma (CC) treated with definitive radiation. Methods. A retrospective, dual-institution review of patients with Stage IB2-IVA CC from 2005 to 2015. Progression-free (PFS) and Overall Survival (OS) were determined for high and low CLC, CNC, and CMC groups. Multivariate analysis was used to confirm prognostic value of baseline leukocyte counts. Results. 181 patients were included. Median follow-up time was 26 (3–89) months. CNC had no effect on PFS or OS. PFS was similar between CMC groups; however, OS was significantly improved for patients with low CMC (62.5 versus 45.3 months, p = 0.016). High CLC was associated with improved PFS (48.5 versus 27.8 months, p = 0.048) and OS (58.4 versus 34.9 months, p = 0.048). On multivariate analysis, high CNC was associated with increased relapse risk (HR 1.12, p = 0.006) and low CLC was associated with increased mortality risk (HR 0.67, p = 0.027). Conclusion. This study demonstrates that leukocyte values can provide prognostic information in CC. These hypothesis-generating findings warrant further prospective investigations. PMID:28239396

    The prognosis of esophageal cancer patients is still unsatisfactory. Although a docetaxel, cisplatin, and 5-Fu (DCF) regimen has been reported, it is often difficult to accomplish because of severe toxicity. Therefore, we developed a new biweekly DCF (Bi-DCF) regimen and previously reported the recommended dose in a phase I dose-escalation study. We then performed a phase II study of Bi-DCF for advanced esophageal squamous cell carcinoma (SCC). Patients with clinical stage II/III were eligible. Patients received 2 courses of chemotherapy: docetaxel 35 mg/m(2) with cisplatin 40 mg/m(2) on days 1 and 15 and 400 mg/m(2) 5-fluorouracil on days 1-5 and 15-19 every 4 weeks. After completion of the chemotherapy, patients received esophagectomy. The primary endpoint was the completion rate of protocol treatment. Thirty-two patients were enrolled. The completion rate of protocol treatment (completion of two courses of preoperative chemotherapy and R0 surgery) was 100 %. During chemotherapy, the most common grade 3 or 4 toxicities were neutropenia (31.3 %). No treatment-related death was observed, and the incidence of operative morbidity was tolerable. The overall response rate after the chemotherapy was 90.3 %. This Bi-DCF regimen was well tolerated and highly active. This trial was registered with the University Hospital Medical Information Network (No. UMIN 000014625).

    Multidisciplinary treatment comprising surgery, chemotherapy, and radiotherapy for resectable esophageal squamous cell carcinoma (ESCC) is widely used with improved prognosis. Transthoracic esophagectomy (TTE) with extended lymph node (LN) dissection, known as three field LN dissection, has been recommended for ESCC using open thoracotomy or the thoracoscopic approach. The Japan Clinical Oncology Group (JCOG) trial (JCOG1409) is investigating the patients’ long term survival using the thoracoscopic approach that has been shown to reduce the incidence of postoperative respiratory complication. For perioperative treatment, neoadjuvant chemotherapy using cisplatin plus 5-fluorouracil (5-FU), has been accepted as the standard of care in Japan based on the JCOG9907 trial. In Western countries, neoadjuvant chemoradiotherapy was shown to prolong overall survival for esophageal cancer, including ESCC. Although surgery has been recognized as an initial curative treatment for esophageal cancer, definitive chemoradiotherapy is an alternative treatment for patients who are unable to undergo thoracotomy or who decline to undergo surgery. This article reviews multidisciplinary treatment advances for ESCC. However, current standard treatments are country dependent and the ongoing trial may help standardize ESCC treatment across various societies. PMID:27384595

    Primary non-Hodgkin's lymphoma of the cervix is a rare disease, of which a subgroup of follicular lymphoma constitutes only 8.5%. There is not an established treatment protocol neither for primary cervical lymphoma nor for its follicular subgroup. We presented a case with Ann Arbor stage IEA (Extra-nodal involvement and absence of weight loss, fever, night sweat) primary follicular lymphoma of the cervix. She was treated with chemotherapy followed by pelvic radiotherapy. Upon relapse with a nodal neck mass, she was treated with rituximab alone. She remained well for 23 months after rituximab. In the 39 months of follow-up, there was no evidence of disease. In the light of our case, we reviewed the reported cases of primary follicular lymphoma of the cervix while discussing their treatment protocols and the cases of primary cervix lymphoma treated with rituximab.

    In cases of advanced renal cell carcinoma with inferior vena cava (IVC) thrombus, surgical resection of both tumor and thrombus contributes to the improvement of patient's prognosis, but the risk of perioperative complication is still high. We experienced two cases of advanced renal tumors with IVC tumor thrombus down-sized by presurgical treatment of axitinib. Axitinib treatment showed a marked tumor reduction effect without any severe adverse event. We could remove both tumor and thrombus without perioperative complications. In these two cases, downsizing of IVC thrombus enabled us to reduce the extent of the surgery.

    The main objective of this paper was to assess the influence of educational level on the survival of uterine cervix cancer patients in our population. A total of 224 patients were registered in our registry, of which 178 had information on stage and different educational levels. The overall median survival (MS) was 23 months, with values of 18.5, 20.7 and 41.3 months for the illiterate, literate and qualified groups, respectively. In the illiterate patients, stage I was seen in 2.6% and stage IV in 11.8%, while in other 2 groups stage I was seen in 10% to 17% of patients at the time of diagnosis. The survival probability at around 50 months was around 42%, 30% and 26% (approximately) for qualified, literates and illiterates respectively [Log Rank (Mantel-Cox) showed p=0.023]. Emphasis on imparting education to females can be a part of comprehensive cancer control programme for improving the overall survival in patients with carcinoma of the uterine cervix in our population.

    Examination of the cervix was carried out on 2,400 patients, by use of acetic acid test with the naked eye and the colposcope. The physiologic transformation zone was clearly identified both with the naked eye and the colposcope in 1,568 of 1,594 (99%) cases. Colposcopic examination was unsatisfactory in 108 of the 264 (41%) patients in whom the cervix was completely covered by normal squamous epithelium. An atypical transformation zone (ATZ) was identified with the naked eye as white epithelium in 98.4% and as "suspicious" in 1.6% of 312 colposcopically controlled cases. An unsatisfactory colposcopic examination occurred in 39 of the 312 (12.5%) patients with an ATZ. Final histologic diagnosis for 312 ATZs was benign lesion in 169 of 312 (54.2%), cervical intraepithelial neoplasia (CIN) grades 1 and 2 in 81 of 312 (26%), grade 3 CIN in 56 of 312 (17.9%), and preclinical invasive carcinoma in 6 of 312 (1.9%). The detection of intraepithelial or preclinical invasive cervical neoplasias should not depend on the possession of a colposcope. On the other hand, the use of a colposcope is essential for the selection of CIN that can be treated with ultraconservative therapy or with colposcopically directed conization.

    One hundred and twenty-seven patients with previously untreated carcinoma of the uterine cervix underwent pretreatment laparotomy between 1971 and 1980. Thirty-one were found to have paraaortic metastasis. Twenty-seven patients received paraaortic node external supervoltage radiation to the entire paraaortic chain, 4400 cGy, over 4 1/2 weeks, with 600-800 cGy, boost over 1 week, limited to the area of metastasis as marked at laparotomy. Twenty-nine percent (8/27) of the patients with paraaortic node metastases who were irradiated have survived 5 years or more. Three of five patients (60%) with microscopic metastasis and five of twenty-two patients (23%) with gross metastasis in the paraaortic lymph nodes are long-term survivors. None of our long-term survivors have suffered late complications. There have been no fatalities from treatment related complications. The authors present a radiation technique for paraaortic radiation in these patients, and discuss the indications for paraaortic node radiation in cancer of the cervix.

    Short-course preoperative radiotherapy (RT) is widely used in northern Europe for locally advanced resectable rectal cancer, but its role in the era of advanced imaging techniques is uncertain. Here, we reviewed articles and abstracts on SCRT published from 1974 through 2013 with the goal of identifying patients who might be best suited for short-course RT. We included relevant articles comparing surgery with or without preoperative radiation published before and after the advent of total mesorectal excision. We also analyzed two randomized trials directly comparing short-course RT with conventionally fractionated chemoradiation (the Polish Colorectal Study Group and the Trans-Tasman Radiation Oncology Group) that compared short-course RT with conventional chemoradiotherapy. We conclude from our review that short-course RT can be generally applied for operable rectal cancer and produces high rates of pelvic control with acceptable toxicity; it reduces local recurrence rates but does not increase overall survival. SCRT seems to be best used for tumors considered “low risk,” i.e., those that are >5 cm from the anal margin, without circumferential margin involvement, and involvement of fewer than 4 lymph nodes. Whether sequential chemotherapy can further improve outcomes remains to be seen, as does the best time for surgery (immediately or 6–8 weeks after RT). We further recommend that selection of patients for short-course RT should be based on findings from magnetic resonance imaging or transrectal ultrasonography. PMID:25535578

    Purpose: This phase 2 study evaluated the efficacy of radiation therapy (RT) with concurrent and sequential sorafenib therapy in patients with unresectable hepatocellular carcinoma (HCC). Methods and Materials: Forty patients with unresectable HCC unfit for transarterial chemoembolization were treated with RT with concurrent and sequential sorafenib. Sorafenib was administered from the commencement of RT at a dose of 400 mg twice daily and continued to clinical or radiologic progression, unacceptable adverse events, or death. All patients had underlying Child-Pugh A cirrhosis. The maximal tumor diameter ranged from 3.0 cm to 15.5 cm. Coexisting portal vein thrombosis was found in 24 patients and was irradiated simultaneously. The cumulative RT dose ranged from 40 Gy to 60 Gy (median, 50 Gy). Image studies were done 1 month after RT and then every 3 months thereafter. Results: Thirty-three (83%) completed the allocated RT. During RT, the incidence of hand-foot skin reactions ≥ grade 2 and diarrhea were 37.5% and 25%, respectively, and 35% of patients had hepatic toxicities grade ≥2. Twenty-two (55.0%) patients achieved complete or partial remission at the initial assessment, and 18 (45%) had stable or progressive disease. The 2-year overall survival and infield progression-free survival (IFPS) were 32% and 39%, respectively. A Cancer of the Liver Italian Program (CLIP) score ≥2 was associated with an inferior outcome in overall survival. Six patients (15%) developed treatment-related hepatic toxicity grade ≥3 during the sequential phase, and 3 of them were fatal. Conclusions: When RT and sorafenib therapy were combined in patients with unresectable HCC, the initial complete or partial response rate was 55% with a 2-year IFPS of 39%. A CLIP score ≥2 was associated with an inferior outcome in overall survival. Hepatic toxicities are a major determinant of the safety; the combination should be used with caution and needs further investigation.

Images of healthy endometrium in different stages of menstrual cycle have been recorded. For uterine cervix not only OCT data of normal state but some kids of pathology have been analyzed. Capability of OCT to identify alterations of mucosa makes this method promising for early diagnosis of tumors and precise guiding of excisional biopsy.

    Objectives To determine the efficacy and safety of single agent sorafenib, an oral multi-targeted tyrosine kinase inhibitor, in patients with advanced uterine carcinoma and carcinosarcoma. Methods This multi-institutional non-randomized phase II trial enrolled two cohorts: patients with uterine carcinoma (cohort A) and uterine carcinosarcoma (cohort B). Eligibility criteria included measurable disease, 0–1 prior chemotherapy regimens, and ECOG performance status ≤ 2. Sorafenib at a dose of 400 mg was administered orally twice daily. A cycle was defined as 28 days. Objective tumor response was the primary endpoint and was assessed following every two cycles. Results Fifty–six patients (40 with carcinoma, 16 with carcinosarcoma) were enrolled between March 2005 and August 2007. Two (5%) patients with uterine carcinoma had a partial response (PR) and 17 (42.5%) achieved stable disease (SD). Five had SD lasting at least 4 months. The 6-month progression free survival rate for patients with carcinoma was 29%, and the median overall survival was 11.4 months. No patients with carcinosarcoma had an objective response. Four (25%) had SD, and one had SD lasting 18 months. The 6-month progression free survival rate was 13%, and the median overall survival was 5.0 months. Grade 3/4 drug related toxicities included: hypertension (13%), hand-foot syndrome (13%), hypophosphatemia (7%), anemia (5%), rash (5%), diarrhea (5%), thrombosis (5%), fatigue (5%) and bleeding (5%). Conclusion Sorafenib had minimal activity in patients with uterine carcinoma. Predictive factors for potential benefit are needed. PMID:20117828

    A 65-year-old Japanese male farmer with advanced gastric adenocarcinoma and multiple hepatic metastases was admitted to our hospital. Blood culture results were positive on day 5, and Gram-positive rods were detected. According to the results of Ziehl-Neelsen staining and a cultured colony of this bacterium, we suspected a mycobacterial infection. Suspecting a rapidly growing mycobacterium (RGM), we started multidrug therapy with levofloxacin, clarithromycin, and ethambutol, and the patient recovered from the bloodstream infection. Further gene examination (16S rRNA, hsp65, and sodA) revealed an isolate of Mycobacterium conceptionense. M. conceptionense was first identified as an RGM in 2006. Among previous case reports of M. conceptionense infections, bone and soft tissue infections in hosts with a disorder of the normal structure (e.g., surgical sites) were dominant. We report the characteristics of M. conceptionense infection in this first Japanese case report and a review of the literature.

    Non-small-cell lung cancer (NSCLC) remains the leading cause of cancer-related death in both men and women in the United States. Platinum-based doublet chemotherapy has been a standard for patients with advanced stage disease. Improvements in overall survival and quality of life have been modest. Improved knowledge of the aberrant molecular signaling pathways found in NSCLC has led to the development of biomarkers with associated targeted therapeutics, thus changing the treatment paradigm for many NSCLC patients. In this review, we present a summary of many of the currently investigated biologic targets in NSCLC, discuss their current clinical trial status, and also discuss the potential for development of other targeted agents.

    2010-01-01

    Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma (HCC) in vitro and palliative efficacy in advanced HCC in two independent phase II trials. The aim of this study was to assess the efficacy of thymostimulin in a phase III trial. Methods The study was designed as a prospective randomised, placebo-controlled, double-blind, multicenter clinical phase III trial. Between 10/2002 and 03/2005, 135 patients with locally advanced or metastasised HCC (Karnofsky ≥60%/Child-Pugh ≤ 12) were randomised to receive thymostimulin 75 mg s.c. 5×/week or placebo stratified according to liver function. Primary endpoint was twelve-month survival, secondary endpoints overall survival (OS), time to progression (TTP), tumor response, safety and quality of life. A subgroup analysis according to liver function, KPS and tumor stage (Okuda, CLIP and BCLC) formed part of the protocol. Results Twelve-month survival was 28% [95%CI 17-41; treatment] and 32% [95%CI 19-44; control] with no significant differences in median OS (5.0 [95% CI 3.7-6.3] vs. 5.2 [95% CI 3.5-6.9] months; p = 0.87, HR = 1.04 [95% CI 0.7-1.6]) or TTP (5.3 [95%CI 2.0-8.6] vs. 2.9 [95%CI 2.6-3.1] months; p = 0.60, HR = 1.13 [95% CI 0.7-1.8]). Adjustment for liver function, Karnofsky status or tumor stage did not affect results. While quality of life was similar in both groups, fewer patients on thymostimulin suffered from accumulating ascites and renal failure. Conclusions In our phase III trial, we found no evidence of any benefit to thymostimulin in the treatment of advanced HCC and there is therefore no justification for its use as single-agent treatment. The effect of thymostimulin on hepato-renal function requires further confirmation. Trial Registration Current Controlled Trials ISRCTN64487365. PMID:20735834

  18. Budget impact analysis of first-line treatment with pazopanib for advanced renal cell carcinoma in Spain

    PubMed Central

    2013-01-01

    Background Due to economic constraints, cancer therapies are under close scrutiny by clinicians, pharmacists and payers alike. There is no published pharmacoeconomic evidence guiding the choice of first-line therapy for advanced renal cell carcinoma (RCC) in the Spanish setting. We aimed to develop a model describing the natural history of RCC that can be used in healthcare decision-making. We particularly analyzed the budget impact associated with the introduction of pazopanib compared to sunitinib under the Spanish National Healthcare System (NHS) perspective. Methods We developed a Markov model to estimate the future number of cases of advanced RCC (patients with favorable or intermediate risk) resulting either from initial diagnosis or disease progression after surgery. The model parameters were obtained from the literature. We assumed that patients would receive either pazopanib or sunitinib as first-line therapy until disease progression. Pharmacological costs and costs associated with the management of adverse events (AE) were considered. A univariate sensitivity analysis was undertaken in order to test the robustness of the results. Results The model predicted an adult RCC prevalence of 7.5/100,000 (1-year), 20.7/100,000 (3-year) and 32.5/100,000 (5-year). These figures are very close to GLOBOCAN reported RCC prevalence estimates of 7.6/100,000, 20.2/100,000 and 31.1/100,000, respectively. The model predicts 1,591 advanced RCC patients with favorable or intermediate risk in Spain in 2013. Annual per patient pharmacological costs were €32,365 and €39,232 with pazopanib and sunitinib, respectively. Annual costs associated with the management of AE were €662 and €974, respectively. Overall annual per patient costs were €7,179 (18%) lower with pazopanib compared to sunitinib. For every point increase in the percentage of patients treated with pazopanib, the NHS would save €67,236. If all the 1,591 patients predicted were treated with pazopanib, the

    Long non-coding RNA (lncRNA) plays an important role in tumorigenesis. However, the expression pattern and function of lncRNAs in laryngeal squamous cell carcinoma (LSCC) are still unclear. To investigate the aberrantly expressed lncRNAs and mRNAs in advanced LSCC, we screened lncRNA and mRNA expression profiles in 9 pairs of primary Stage IVA LSCC tissues and adjacent non-neoplastic tissues by lncRNA and mRNA integrated microarrays. Gene Ontology and pathway analysis were performed to find out the significant function and pathway of the differentially expressed mRNAs, gene-gene functional interaction network and ceRNA network were constructed to select core mRNAs, and lncRNA-mRNA expression correlation network was built to identify the interactions between lncRNA and mRNA. qRT-PCR was performed to further validate the expressions of selected lncRNAs and mRNAs in advanced LSCC. We found 1459 differentially expressed lncRNAs and 2381 differentially expressed mRNAs, including 846 up-regulated lncRNAs and 613 down-regulated lncRNAs, 1542 up-regulated mRNAs and 839 down-regulated mRNAs. The mRNAs ITGB1, HIF1A, and DDIT4 were selected as core mRNAs, which are mainly involved in biological processes, such as matrix organization, cell cycle, adhesion, and metabolic pathway. LncRNA-mRNA expression correlation network showed LncRNA NR_027340, MIR31HG were positively correlated with ITGB1, HIF1A respectively. LncRNA SOX2-OT was negatively correlated with DDIT4. qRT-PCR further validated the expression of these lncRNAs and mRNAs. The work provides convincing evidence that the identified lncRNAs and mRNAs are potential biomarkers in advanced LSCC for further future studies. PMID:28033431

    The prognosis for hepatocellular carcinoma with extrahepatic metastasis or vascular invasion is very poor. We treated a case successfully by combining chemotherapy and liver resection for hepatocellular carcinoma with multiple pulmonary metastases and vascular invasion. A 56-year-old man who complained of abdominal pain in his right side was transported to the hospital by ambulance. Because CT scan revealed the rupture of hepatocellular carcinoma, he underwent emergency transcatheter arterial embolization (TAE). A close examination revealed tumor thrombus in the inferior vena cava and posterior segment of the portal vein branch, with multiple pulmonary metastases. We conducted right hepatic lobectomy and removal of the inferior vena cava tumor thrombus. After the operation, pulmonary metastatic lesions gradually grew larger, so the oral administration of S-1 at 120 mg per day was started. At the end of the first course, the CT scan revealed that multiple pulmonary metastases were significantly reduced, and treatment was maintained until the end of 4 courses. A prolongation of survival could be expected by combining systemic chemotherapy and liver resection for advanced hepatocellular carcinoma such as the present case.

  2. Pseudoneoplastic glandular lesions of the uterine cervix: a selective review.

    2014-07-01

    Pseudoneoplastic glandular lesions of the cervix continue to be diagnostically challenging for the surgical pathologist. This review covers a select number of these lesions that may be misinterpreted as premalignant or malignant, with an emphasis on those about which Dr Scully has advanced our knowledge. The topics covered include microglandular hyperplasia, mesonephric hyperplasia, diffuse laminar endocervical glandular hyperplasia, lobular endocervical glandular hyperplasia, and endocervical adenomyoma. The first listed entity has a greater diversity of morphology than the name might imply including, but not limited to solid growth and prominent hyaline stroma. The second entity may be remarkably diffuse within the cervical wall and reasonably result in consideration of diagnoses such as minimal deviation adenocarcinoma (adenoma malignum), but has nonmucinous epithelium and bland cytology. The third entity, one of the least common of those considered, represents a peculiar form of reactive hyperplasia of the endocervical epithelium. The fourth entity is the one about which knowledge is still fast advancing. In pure form with no atypia it is almost certainly a clinically benign process, but a subset of cases show cytologic atypia and an occasional association with adenocarcinoma is seen. Finally, adenomyomas of the uterus in general have received much attention in recent years, mostly in the corpus, but the less common endocervical variant may be particularly problematic because mucinous epithelium in abundant myogenic stroma may be potentially confused with an infiltrating differentiated mucinous adenocarcinoma. Although immunohistochemistry may play a role on occasion in evaluating benign endocervical glandular proliferations the mainstay of their interpretation remains conventional morphologic analysis of routinely stained slides.

    The authors treated 14 patients who had advanced head and neck cancer with an accelerated fractionation schedule of irradiation consisting of two fractions given 6 hours apart. In the morning a volume of 1.7 Gy was given to an area that encompassed the entire tumor, enlarged lymph nodes, and all areas at risk for microscopic disease. Six hours later, 1.1 Gy was given to an area that included only the tumor and any enlarged lymph nodes, with a 2-cm margin. The treatment was well tolerated; of the 13 patients who completed therapy, six did not require a break in therapy, and seven patients did. The median rest period was 2 days. There was no grade 4 toxicity. Grade 3 toxicity included skin changes (one case), mucositis (two), dysphagia (two), weight loss (three), and a decrease in the hemoglobin level (one case). The response rate in the 13 who completed therapy was 13/13 (100%); 11 of the 13 (83%) had a complete response. Only one of the 11 who achieved a complete response had failure at the primary site. At a median follow-up of 24 months, the absolute survival was 7/13 (54%) and the corrected survival was 7/10 (70%). This technique permits radiation therapy to be given on an accelerated schedule without a planned break in treatment. The overall response rate and survival at 2 years was excellent.

    Aim of the study Irreversible electroporation is a new, non-thermal ablation technique in the treatment of parenchymal organ tumors which uses short high voltage pulses of electricity in order to induce apoptosis of targeted cells. In this paper the application of this method of treatment in locally advanced pancreatic cancer (LAPC) and liver cancer is analyzed. Material and methods Between 04.2014 and 09.2014 two patients with LAPC and one with colorectal liver metastasis (CRLM) were qualified for treatment with irreversible electroporation. Both patients remained under constant observation and control. PubMed/Medline, Embase and Google Scholar databases were searched and eight original reports on irreversible electroporation of pancreatic and liver tumors based on the biggest groups of patients were found. Results Two patients with LAPC and one with CRLM were qualified for ablation with irreversible electroporation. In all three patients a successful irreversible electroporation (IRE) procedure of the whole tumor was conducted. In the minimum seven-month follow-up 100% local control was achieved – without progression. In the literature review the local response to treatment ranged from 41% to 100%. The event-free survival rate in six-month observation was 94%. Conclusions Ablation with irreversible electroporation is a new non-thermal ablation technique which has been demonstrated, both in the previously published studies and in the cases described in this paper, as a safe and efficient therapeutic method for patients with LAPC and CRLM.

    Treatment of oral and oropharyngeal cancer may cause dysphagia. Purpose is to examine whether cine magnetic resonance imaging (MRI) yields additional information compared to standard examination in the evaluation of posttreatment dysphagia and mobility of oral and oropharyngeal structures. Thirty-four cine MRIs were made in 23 patients with advanced oral and oropharyngeal cancer, consisting of an MR image every 800 ms during swallowing which is compared to videofluoroscopy and quality of life questionnaires. A scoring system was applied to assess mobility on cine MR and videofluoroscopy leading to a score ranging from 9 to 17. Cine MRI of the swallowing in a midsagittal plane visualized the tumor (if located in the same plane), important anatomic structures and surgical reconstructions. Posttreatment mobility on cine MRI and videofluoroscopy was significantly diminished compared to pretreatment, mean pretreatment cine MRI score was 10.8 and posttreatment 12.4 (p = 0.017). Impaired mobility on cine MRI was significantly correlated to more swallowing problems (Spearman's correlation coefficient 0.73, p = 0.04), on videofluoroscopy not. Cine MRI is a promising new technique as an adjunct to standard examinations for evaluation of swallowing in patients with oral and oropharyngeal cancer. Cine MRI directly visualizes the dynamics of swallowing and allows evaluation of pre- and posttreatment differences. Abnormal findings are significantly correlated with subjective swallowing complaints of patients.

    Three hundred forty-five patients with Stage IB squamous cell carcinoma of the cervix were treated at the University of Michigan Medical Center from 1970 to 1985. The overall cumulative 5-year survival rate was 89% and the mean age was 44.6 years. In 213 patients undergoing radical hysterectomy the cumulative 5-year survival rate was 92%; 14 patients were explored for radical hysterectomy that was not performed due to high risk features and their survival rate was 50%. Ninety-seven patients underwent radiation therapy as initial treatment and had a 5-year survival rate of 86%. There was no significant difference when radiation therapy was compared with radical hysterectomy (P = 0.098). The survival rates for lesions 3 cm or smaller were 94% for radical hysterectomy and 88% for radiation therapy. When the lesion was larger than 3 cm, the survival rates were 82% with radical surgery and 73% with radiation therapy. Metastatic disease to lymph nodes was present in 26 of the 213 patients undergoing radical hysterectomy. When 1 to 3 nodes were involved 16 of 19 patients survived and when 4 to 10 nodes were involved 3 of 7 patients survived. The addition of radiation therapy did not influence survival. Complications were similar in both treatment groups. Fistulas occurred in 4 of 213 patients undergoing radical hysterectomy and 1 of 111 undergoing radiation. Second surgery for a complication was required in 6 of 213 patients undergoing radical hysterectomy and 7 of 111 undergoing radiation. Survival and complication rates in early stage squamous cell carcinoma of the cervix are equal with either radical surgery or radiation therapy.

    Oral squamous cell carcinoma (OSCC) is one of the most common cancers worldwide. Aberrations in miRNA regulation are known to play important roles in OSCC pathogenesis. miR-187 was shown to be up-regulated in head and neck malignancies in our previous screening. This study further investigated the oncogenic potential, clinical implications, and targets of miR-187 in OSCC. We observed that miR-187 increased oncogenicity, particularly migration, of OSCC cells. miR-187 expression increased the xenografic tumorigenicity and metastasis in mice. In addition, metastatic human OSCC had higher miR-187 expression than did non-metastatic tumors. Through vigorous screening, we confirmed BarH-like Homeobox 2 (BARX2) gene as an miR-187 target. BARX2 expression suppressed the migration, invasion, anchorage-independent colony formation, and orthotopic tumorigenesis of OSCC cells. The migratory phenotype and neck metastasis induced by miR-187 was rescued by BARX2 expression. BARX2 expression was down-regulated in the vast majority of OSCC, and this down-regulation was particularly conspicuous in tumors with advanced nodal metastasis. In addition, plasma miR-187 was significantly higher in OSCC patients than in normal individuals. This study highlights the roles of miR-187-BARX2 in driving the carcinogenesis of OSCC. The results suggest that miR-187 is a potential serological marker for OSCC and that targeting of miR-187 might prove effective in attenuating nodal metastasis. PMID:27542258

    Purpose: To examine clinical outcomes and relapse patterns in locally advanced vulvar carcinoma treated using preoperative chemotherapy and intensity modulated radiation therapy (IMRT). Methods and Materials: Forty-two patients with stage I-IV{sub A} (stage I, n=3; stage II, n=13; stage III, n=23; stage IV{sub A}, n=3) vulvar cancer were treated with chemotherapy and IMRT via a modified Gynecological Oncology Group schema using 5-fluorouracil and cisplatin with twice-daily IMRT during the first and last weeks of treatment or weekly cisplatin with daily radiation therapy. Median dose of radiation was 46.4 Gy. Results: Thirty-three patients (78.6%) had surgery for resection of vulva; 13 of these patients also had inguinal lymph node dissection. Complete pathologic response was seen in 48.5% (n=16) of these patients. Of these, 15 had no recurrence at a median time of 26.5 months. Of the 17 patients with partial pathological response, 8 (47.1%) developed recurrence in the vulvar surgical site within a median of 8 (range, 5-34) months. No patient had grade ≥3 chronic gastrointestinal/genitourinary toxicity. Of those having surgery, 8 (24.2%) developed wound infections requiring debridement. Conclusions: Preoperative chemotherapy/IMRT was well tolerated, with good pathologic response and clinical outcome. The most common pattern of recurrence was local in patients with partial response, and strategies to increase pathologic response rate with increasing dose or adding different chemotherapy need to be explored to help further improve outcomes.

    Objective: The biology of high grade serous ovarian carcinoma (HGSOC) is poorly understood. Little has been reported on intratumoral homogeneity or heterogeneity of primary HGSOC tumors and their metastases. We evaluated the global protein expression profiles of paired primary and metastatic HGSOC from formalin-fixed, paraffin-embedded (FFPE) tissue samples. Methods: After IRB approval, six patients with advanced HGSOC were identified with tumor in both ovaries at initial surgery. Laser capture microdissection (LCM) was used to extract tumor for protein digestion. Peptides were extracted and analyzed by reversed-phase liquid chromatography coupled to a linear ion trap mass spectrometer. Tandem mass spectra were searched against the UniProt human protein database. Differences in protein abundance between samples were assessed and analyzed by Ingenuity Pathway Analysis software. Immunohistochemistry (IHC) for select proteins from the original and an additional validation set of five patients was performed. Results: Unsupervised clustering of the abundance profiles placed the paired specimens adjacent to each other. IHC H-score analysis of the validation set revealed a strong correlation between paired samples for all proteins. For the similarly expressed proteins, the estimated correlation coefficients in two of three experimental samples and all validation samples were statistically significant (p < 0.05). The estimated correlation coefficients in the experimental sample proteins classified as differentially expressed were not statistically significant. Conclusion: A global proteomic screen of primary HGSOC tumors and their metastatic lesions identifies tumoral homogeneity and heterogeneity and provides preliminary insight into these protein profiles and the cellular pathways they constitute.

    Purpose The main aim of this study is to analyze the prognostic differences in nasopharyngeal carcinoma (NPC) patients who are positive and negative for Epstein-Barr virus (EBV). Results Of the 1106 patients, 248 (22.4%) had undetectable pre-treatment plasma EBV DNA levels. The total distant metastasis rate for EBV-negative group vs. EBV-positive group were 3.6% (9/248) vs. 15.0% (128/858) (P < 0.001). The estimated 4-year disease-free survival (DFS), overall survival (OS), distant metastasis-free survival (DMFS) and locoregional relapse-free survival (LRRFS) for EBV-negative group vs. EBV-positive group were 88.9% vs. 76.9% (P < 0.001), 93.6% vs. 85.9% (P = 0.001), 96.7% vs. 84.8% (P < 0.001) and 94.1% vs. 90.0% (P = 0.1), respectively. Multivariate analysis revealed that the EBV status was an independent prognostic factor for DFS (HR, 1.813; 95% CI, 1.219-2.695; P = 0.003), OS (HR, 1.828; 95% CI, 1.075-3.107; P = 0.026) and DMFS (HR, 3.678; 95% CI, 1.859-7.277; P <0.001), and overall stage still remained the most important prognostic factor in patients with stage III-IVB NPC. Methods and Materials Data on 1106 patients with non-metastatic, histologically proven advanced-stage (III-IVB) NPC who underwent intensity-modulated radiotherapy (IMRT) were retrospectively reviewed. Patient survival between different EBV status groups were compared. Conclusions EBV status was an independent prognostic factor for patients with stage III–IVB NPC. Neoadjuvant chemotherapy (NCT) plus concurrent chemoradiotherapy (CCRT) should be better treatment regimen for EBV-positive patients since distant metastasis was the main failure pattern, and CCRT may be enough for EBV-negative patients.

Median overall survival in patients with baseline alpha-fetoprotein ≥ 400 ng/mL was 7.8 months for ramucirumab and 4.2 months for placebo (HR, 0.749; 95% CI, 0.519–1.082; p = 0.1213) for East Asians (n = 139), and 8.2 months for ramucirumab and 4.5 months for placebo (HR, 0.579; 95% CI, 0.371–0.904; p = 0.0149) for non-East Asians (n = 111). The most common grade ≥ 3 treatment-emergent adverse events in East Asians and non-East Asians included hypertension and malignant neoplasm progression. Materials and methods A post-hoc analysis of East Asians (N = 252) and non-East Asians (N = 313) in the intent-to-treat population was performed. Conclusions In East Asians and non-East Asians, ramucirumab did not significantly prolong overall survival. In patients with baseline alpha-fetoprotein ≥ 400 ng/mL, a potentially larger survival benefit was observed in both subgroups. Safety for East Asians was similar to non-East Asians. PMID:27776351

    The objective of this study was to evaluate the prevalence of regional and distant metastasis in cats with advanced oral squamous cell carcinoma (SCC) in a retrospective case series. Forty-nine cats with cytologically- or histopathologically-confirmed oral SCC presented to the Matthew J Ryan Veterinary Hospital of the University of Pennsylvania. History, clinical and laboratory results, diagnostic imaging findings and survival times were obtained from the medical records of patients who received diagnostic evaluation for metastasis. The prevalence of metastasis was assessed by means of mandibular lymph node cytology and three-view thoracic radiography. The prevalence of mandibular lymph node metastasis was 31% (15/49). Evidence of possible thoracic metastasis was seen in 10% (5/49) of cases. Of the patients with mandibular lymph node metastasis, 53% (8/15) were maxillary, 27% mandibular (4/15), 13% sublingual (2/15) and 7% caudal pharyngeal (1/15). Pulmonary metastasis was seen in three mandibular, one maxillary and one sublingual mass. Forty-one patients died or were euthanased owing to progression of local disease, and seven patients were lost to follow-up. The prevalence of regional metastasis in this study was more common than most previously reported studies, while the rate of pulmonary metastasis was higher than has previously been published. Although significant conclusions cannot be drawn, control of the primary tumor, regardless of tumor size at diagnosis, appears to be an important factor in improving survival time, and therefore treatment of metastasis may be important in those cases where long-term control of the primary tumor is possible.

    We have analyzed the results of photodynamic therapy using light-sensitizing agent "Photogem" in 72 patients - 56 women with pre-cancerous lesions of cervix and 16 women with early cervical cancer (group 1); Photosens in 47 patients - 35 women with pre-cancerous lesions (CIN III), 12 women with non-invasive cervical cancer (carcinoma in situ) (group 2); and Alasens in 22 patients - 8 women with virus-associated pre-cancerous lesions (high-grade CIN III), 14 with virus-associated early cervical cancer (carcinoma in situ, cervical cancer 1A1) (group 3). The results were as follows: group 1 - complete regression of CIN III and non-invasive cervical cancer (carcinoma in situ) was achieved in 50 (89.2%) and 11 (68.8%) cases, significant regression was achieved in 2 cases (3.6%) and in 2 cases (12.5%), stabilization was achieved in 2 cases (3.6%) and in 2 cases (12.5%), progression was achieved in 2 cases (3.6%) and in 1 case (6.2%) accordingly. In the group of patients after PDT using Photosens complete regression of CIN III and non-invasive cervical cancer (carcinoma in situ) was achieved in 33 cases (94.2%) and in 10 cases (83.4%) cases, significant regression was achieved in 1 case (2.9%) and in 1 case (8.3%), stabilization was achieved in 1 cases (2.9%) and in 1 cases (8.3%). In the group of women after surgical treatment anti-viral efficacy was assessed. It s necessary to note that not a single relapse was observed. Anti-viral effect was registered in 49 (90.4%) cases The longest HPV-free period that we observed was 5 years. 12 women with CIN III and 4 women with carcinoma in situ became pregnant.

    Introduction At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. Presentation of case A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. Discussion The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Conclusion Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    The use of gemcitabine and oxaliplatin is well documented in selected patients with advanced biliary tract carcinoma (BTC), but little is known on the feasibility of systemic treatments in patients with a performance status (PS) of 2. We retrospectively examined the medical records of consecutive BTC patients with a PS of 2 receiving gemcitabine 1000 mg/m(2) plus oxaliplatin 100 mg/m(2) every 2 weeks from January 2003 to December 2011 in our institution. Body composition was analysed by computed tomography scan to detect sarcopenia. The primary evaluation criterion was safety. The secondary evaluation criteria were the response rate, progression-free survival (PFS) and overall survival (OS). Twenty-eight patients (median age: 63 years, range 41-83) received a total of 175 cycles (median per patient: 6, range 2-12). Ten patients (35.7%) had sarcopenia on the pretreatment computed tomography scan. The most frequent toxicities were thrombocytopenia (grades 2-4: n=4, 14.3%), peripheral neuropathy (grades 2-3: n=9, 32.1%) and cholangitis (n=4, 14.3%). The best response was a partial response in 10.7% of patients [95% confidence interval (CI): 0-22.2] and stable disease in 42.9% of patients. The median PFS and OS were 4.6 (95% CI: 2.5-6.3) and 7.5 (95% CI: 5.2-9.5) months, respectively. The median PFS and OS were significantly longer in patients without sarcopenia: 7.0 months (95% CI: 4.4-8.0) vs. 2.2 months (95% CI: 2.0-2.5), P less than 0.01, and 10.4 months (95% CI: 7.5-11.6) vs. 4.9 months (95% CI: 3.7-5.2), P less than 0.01, respectively. In our experience, gemcitabine-oxaliplatin was feasible and induced effective palliation in PS2 patients with advanced BTC. Further studies are warranted to confirm these findings.

    Objectives Our goals were to explore the spatial variability within the cervix and the sensitivity of shear wave speeds (SWS) to assess softness/stiffness differences in ripened (softened) versus unripened tissue. Methods We obtained SWS estimates from hysterectomy specimens (n=22), a subset of which were ripened (n = 13). Multiple measurements were made longitudinally along the cervical canal on both the anterior and posterior sides of the cervix. Statistical tests of differences in the proximal vs. distal, anterior vs. posterior, and ripened vs. unripened cervix were performed with individual two-sample t-tests and a linear mixed model. Results We discovered that SWS estimates monotonically increase from distal to proximal longitudinally along the cervix, that they also vary in the anterior compared to the posterior cervix, and that they are significantly different in ripened vs. unripened cervical tissue. Specifically, the mid position SWS estimates for the unripened group were 3.45±0.95 m/s (anterior) and 3.56±0.92 m/s (posterior), and 2.11±0.45 m/s (anterior) and 2.68±0.57 m/s (posterior) for the ripened (p<0.001). Conclusions We propose that shear wave speed estimation may be a valuable research and, ultimately, diagnostic tool for objective quantification of cervical stiffness/softness. PMID:23836486

    Although prevalence of Enterobius vermicularis (EV) infestation in Intestines ranges from 35% to 70%, its prevalence in female genital tract is not known despite several incidental findings. Acute inflammatory cells in the background of cervical Pap smear indicate infestation and should not be neglected as contamination. A 40-year-woman presented with white vaginal discharge persistent for past 1 year. Local examination showed hypertrophied cervix with eversion of both lips and hard consistency of the anterior lip of cervix. A clinical diagnosis of cervical carcinoma was made. However, cervical Pap smear indicated EV eggs in an inflammatory background, treatment to which resulted in completely recovery. PMID:26283859

    Cervicography is a technique for visual screening of uterine cervix images for cervical cancer. One of our research goals is the automated detection in these images of acetowhite (AW) lesions, which are sometimes correlated with cervical cancer. These lesions are characterized by the whitening of regions along the squamocolumnar junction on the cervix when treated with 5% acetic acid. Image preprocessing is required prior to invoking AW detection algorithms on cervicographic images for two reasons: (1) to remove Specular Reflections (SR) caused by camera flash, and (2) to isolate the cervix region-of-interest (ROI) from image regions that are irrelevant to the analysis. These image regions may contain medical instruments, film markup, or other non-cervix anatomy or regions, such as vaginal walls. We have qualitatively and quantitatively evaluated the performance of alternative preprocessing algorithms on a test set of 120 images. For cervix ROI detection, all approaches use a common feature set, but with varying combinations of feature weights, normalization, and clustering methods. For SR detection, while one approach uses a Gaussian Mixture Model on an intensity/saturation feature set, a second approach uses Otsu thresholding on a top-hat transformed input image. Empirical results are analyzed to derive conclusions on the performance of each approach.

    Artificial insemination is commonly practiced in several domestic animals, including sows. Postcervical insemination is used to increase the fertility index, given that the volume of semen is optimized. Knowledge of the anatomical and physiological characteristics of the genital tract can be used to improve our understanding of the fertilization process that occurs during artificial insemination, and possibly to improve the technique. The aim of our study was to examine the gross morphology and histological properties of the cervix of recently slaughtered multiparous sows, using different stains. The results indicate that the porcine cervix has two regions: a uterine region characterized by the presence of glandular acini, and a vaginal region with a large vascular network. Both regions showed a mixed secretory activity by epithelial cells, which produced sulfated mucins (mucous secretion), intermingled with abundant glycogen-rich cells (serous secretion). This study contributes to the understanding of the morphologic features of the porcine cervix.

    Premature birth is a social problem due to its implications in the natal mortality and morbidity. This is the reason why it is necessary to establish new methods which could identify pregnant women with high risk of premature birth. Besides the measurable biochemical factors such as fetal fibronectin and salivary estriol, I1-6 sonography is a simple method highly efficient and of reasonable financial costs among all the sonographic means of observing the cervix uteri. The transvaginal sonography is the "golden standard", permitting the most faithful assessment of the pursued parameters--the length of the cervix, the aspect of the internal os (funneling), the cervix index. The experience gathered up to now shows that all of these investigations have a predictive value which is more negative than positive, but when used together they could lead to an improved result.

    Nasopharyngeal carcinoma (NPC) is one of the common cancers in South China. It can easily invade into cranial nerves, especially in patients with local advanced disease. Despite the fact that the magnetic resonance imaging (MRI) findings are not always consistent with the symptoms of CN palsy, MRI is recommended for the detection of CN involvement (CNI). However, the prognostic impact of MRI-detected CNI in NPC patients is still controversial. To investigate the prognostic value of MRI detected CNI, we performed a retrospective analysis on the clinical data of 375 patients with NPC who were initially diagnosed by MRI. All patients had T3-4 disease and received radical intensity modulated radiation therapy (IMRT) as their primary treatment. The incidence of MRI-detected CNI was 60.8%. A higher incidence of MRI-detected CNI was observed in T4 disease compared with T3 disease (96.8% vs. 42.8%, P<0.001), and a higher incidence was also found in patients with Stage IV disease compared with those with Stage III disease (91.5% vs. 42.3%; P<0.001). The local relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) of patients with T3 disease, with or without MRI-detected CNI, was superior to that of patients with T4 disease (P<0.05). No significant differences in LRFS, DMFS or OS were observed between T3 patients with or without MRI-detected CNI. The survival of Stage III patients with or without MRI-detected CNI was significantly superior to that of Stage IV patients (P<0.01), but there was no significant difference between Stage III patients with or without MRI-detected CNI for all endpoints. Therefore, when treated with IMRT, MRI-detected CNI in patients with NPC does not appear to affect the prognosis. In patients with clinical T3 disease, the presence of MRI-detected CNI is not sufficient evidence for defining T4 disease.

    B7x is the newest member of the B7-CD28 family and is thought to dampen immune responses via negative costimulation. Tumor expression of B7x was recently described in renal cell carcinoma (RCC) and was associated with poor outcome. We developed an assay to detect serum soluble B7x (sB7x) and investigated 101 patients with clear cell RCC who underwent nephrectomy between 2003 and 2007. For controls, we obtained serum from 101 sex-matched blood donors within the same age range. Following an Enzyme-Linked Immunosorbent Assay for sB7x, detectable levels (>0.1ng/ml) of sB7x were observed in 53 RCC patients compared with 18 controls (padvanced tumor stage. These early results merit further investigation of this serum marker for potential diagnostic and prognostic purposes. PMID:18676826

    Introduction A 5-flurouracil, Adriamycin, Cyclophosphamide (FAC) and Adriamycin, Paclitaxel (AT) are two popular chemotherapeutic regimens for treatment of breast carcinoma. The most time tested and popular regimen is FAC. It is extensively studied for efficacy and toxicity. But data regarding toxicity profile and efficacy of AT regimen is sparse. Aim To study the toxicity profile, severity of toxicities and clinical response rate of FAC and AT regimens in patients with locally advanced breast carcinoma. Materials and Methods A prospective observational study with 50 patients in each treatment arm. Study duration was 12 months from November 2012 to October 2013. Consecutive patients with locally advanced breast carcinoma receiving treatment with either FAC or AT regimen, satisfying inclusion criteria were enrolled into the study after getting informed written consent. Prior to initiation of treatment detailed medical history was taken from all patients. General clinical examination, examination of organ systems and local examination of breast lump were done. After each cycle of chemotherapy and after completion of treatment patients were interviewed and examined for clinical response and toxicities. Toxicities were graded with WHO toxicity grading criteria. All data were entered in a structured proforma. At least 50% reduction in tumour size was taken as adequate clinical response. Statistical Analysis Data was analysed using Chi-square test with help of Excel 2007 and SPSS-16 statistical software. Results Different pattern of toxicities were seen with FAC and AT regimens. Anaemia, thrombocytopenia, stomatitis, hyperpigmentation, photosensitivity and diarrhoea were more common with patients receiving FAC regimen. Leucopenia, peripheral neuropathy, myalgia, arthralgia, vomiting and injection site reactions were more common in AT regimen. Both FAC and AT regimens gave 100% clinical response. Conclusion FAC and AT regimens are equally efficacious but have different

    Purpose To determine the maximum tolerated dose of oblimersen, an antisense oligonucleotide directed to the Bcl-2 mRNA, in combination with cisplatin and 5-flourouracil in patients with advanced gastric and esophageal carcinoma. Methods Patients were treated with escalating doses of oblimersen administered by continuous intravenous infusion (CIVI) days 1 to7, CIVI 5-fluorouracil (5-FU) days 4 to 7, and cisplatin on day 4 every three weeks. Results Fifteen patients received a total of 49 courses of oblimersen at doses of 3, 5, or 7 mg/kg/d given as a seven day CIVI in combination with 4 or 5 day CIVI of 5-FU (1000 or 750 mg/m2/d) plus intravenous cisplatin (100 or 75 mg/m2 over 2 hours). The recommended phase II dose of oblimersen was 5 mg/kg/day in combination with 5-FU (750 mg/m2/day for 4 days) and cisplatin (75 mg/m2). The most common grade 3 to 4 adverse events that occurred in at least 10% of patients at all dose levels included neutropenia (33%), hypokalemia (27%), infection (20%), and mucositis, fatigue, dizziness, thrombosis, and dehydration (in 13% for each category). Conclusion The combination of oblimersen with 5-FU and cisplatin chemotherapy is feasible in patients with advanced upper gastrointestinal cancer, with antitumor activity observed in gastric carcinoma.

    The phrase "locally advanced carcinoma of the vulva" has often been mentioned in the literature, though not accurately defined, or even leading to the interpretation overlapping. Grounded on cervical cancer experience, we are able to state that designing a tailored primary strategy based on clinically measurable adverse prognostic factors represents the cornerstone of therapy. This fact urged us to rethink about the real usefulness of the concept of locally advanced squamous cell carcinoma of the vulva. We will refer to this concept as a clinical entity emerging from a rigorous workup which is a valuable guiding tool in the context of a thorough debate about the best primary treatment approach to be used. Furthermore, bulky tumors of the vulva have been associated with a worse prognosis on several occasions. Some authors have questioned the fact that tumor size has not been considered in the staging system. Finally, a standardized definition will help us compare the results obtained, which is extremely necessary given the worldwide low prevalence of this disease.

    In vivo Raman spectroscopy is being projected as a new, noninvasive method for cervical cancer diagnosis. In most of the reported studies, normal areas in the cancerous cervix were used as control. However, in the Indian subcontinent, the majority of cervical cancers are detected at advanced stages, leaving no normal sites for acquiring control spectra. Moreover, vagina and ectocervix are reported to have similar biochemical composition. Thus, in the present study, we have evaluated the feasibility of classifying normal and cancerous conditions in the Indian population and we have also explored the utility of the vagina as an internal control. A total of 228 normal and 181 tumor in vivo Raman spectra were acquired from 93 subjects under clinical supervision. The spectral features in normal conditions suggest the presence of collagen, while DNA and noncollagenous proteins were abundant in tumors. Principal-component linear discriminant analysis (PC-LDA) yielded 97% classification efficiency between normal and tumor groups. An analysis of a normal cervix and vaginal controls of cancerous and noncancerous subjects suggests similar spectral features between these groups. PC-LDA of tumor, normal cervix, and vaginal controls further support the utility of the vagina as an internal control. Overall, findings of the study corroborate with earlier studies and facilitate objective, noninvasive, and rapid Raman spectroscopic-based screening/diagnosis of cervical cancers.

    Appropriate mechanical function of the uterine cervix is critical for maintaining a pregnancy to term so that the fetus can develop fully.

    Purpose: To evaluate the risk of geographic miss associated with the classic four-field 'box' irradiation technique and to define the variables that predict this risk. Materials and Methods: The study population consisted of 80 patients with uterine cervix cancer seen between 2001 and 2006. Median age was 55 years (23-82 years), and 72 (90%) presented with squamous cell carcinoma. Most patients (68.7%) presented with locally advanced disease (IIb or more). Magnetic resonance imaging findings from before treatment were compared with findings from simulation of the conventional four-field 'box' technique done with rectal contrast. Study variables included tumor volume; involvement of vagina, parametrium, bladder, or rectum; posterior displacement of the anterior rectal wall; and tumor anteroposterior diameter (APD). Margins were considered adequate when the target volume (primary tumor extension, whole uterine body, and parametrium) was included within the field limits and were at least 1 cm in width. Results: Field limits were inadequate in 45 (56%) patients: 29 (36%) patients at the anterior and 28 (35%) at the posterior border of the lateral fields. Of these, 12 patients had both anterior and posterior miss, and this risk was observed in all stages of the disease (p = 0.076). Posterior displacement of the anterior rectal wall beyond S2-S3 was significantly correlated with the risk of geographic miss (p = 0.043). Larger tumors (APD 6 cm or above and volume above 50 cm{sup 3}) were also significantly correlated with this risk (p = 0.004 and p = 0.046, respectively). Conclusions: Posterior displacement of the anterior rectal wall, tumor APD, and volume can be used as guidance in evaluating the risk of geographic miss.

    Neuroendocrine carcinomas (NEC) of the female genital tract are aggressive and rare tumors that usually involve the cervix and ovary, and are seen rarely in the endometrium in perimenopausal or postmenopausal women. We presented a case of a73 year-old postmenopausal woman with vaginal bleeding and abdominal pain. A subsequent computerized tomography (CT) scan of pelvis showed an enlarged uterus (20,0 × 12,0 cm) with para-aortic and pelvic lymph node metastases. She underwent surgical debulking and staging of an endometrial tumor with omental metastasis and positive lymph nodes. The pathological diagnosis was primary small cell carcinoma (SCC) combined with endometrioid carcinoma of uterine corpus. Her final FIGO stage was IVB. Three months after surgery CT-total body showed a metastasis to left lung of SCC. Because the small-cell component of endometrial tumor showed a strong positivity for TTF1 as pulmonary counterpart a differential diagnosis with a primary small cell carcinoma of the lung should be made. Identifying an appropriate therapeutic management for SCC of endometrium is challenging since these are extremely rare tumors. An optimal initial therapeutic approach to this rare disease, especially at an advanced stage, has not yet been clearly defined. However, in these a multidisciplinary therapy, including surgery, chemotherapy, and radiotherapy represent until this time the only therapeutic option. PMID:26900464

    Vismodegib is a first-in-class, hedgehog-signal inhibitor that is FDA-approved for use with advanced basal cell carcinomas (BCCs) that cannot be removed by either surgical resection or treated with radiation. Release of the drug was fast-tracked because of need for this type of drug, and its overall efficacy in clinical trial by producing either regression or even resolution of advanced BCCs. Compared to placebo, patients using vismodegib have arrested BCC progression, reduced size of BCC, and decreased recurrence of BCC. Unfortunately, vismodegib has notable adverse effects (especially those of alopecia, gastrointestinal, muscle spasms, and dysguesia) that make dermatologists reluctant to prescribe the drug and patients unwilling to undergo therapy. In this article, we tackle this dilemma by comparing the toxicity profile of vismodegib to the adverse effect profiles of other dermatologic chemotherapeutics, immunomodulators, retinoids, and biologics. Considering that many of these drugs carry their own risks and those drugs used to treat advanced melanoma have similar toxicity profiles to that of vismodegib, we hope dermatologists and patients alike will be more willing to try vismodegib as a treatment option for advanced BCCs in the future.

    Objective Long-term survival for patients with advanced endometrial carcinoma is poor, and limited options exist for the management of recurrent disease. Our goal was to investigate the activity of doxorubicin in the second-line setting in patients who progressed after paclitaxel/carboplatin adjuvant treatment. Methods We conducted a retrospective analysis of patients with recurrent endometrial carcinoma who were treated at Memorial Sloan-Kettering Cancer Center from 1995-2009, and who received paclitaxel/carboplatin adjuvant chemotherapy followed by second-line doxorubicin therapy at time of recurrence. The median PFS and OS times following paclitaxel/carboplatin and following second-line doxorubicin therapy were estimated using the Kaplan-Meier method. Toxicity was assessed by the treating physician at each visit and graded using version 4.0 of Common Terminology Criteria for Adverse Events (CTCAE). Patient presentation, treatment, patterns of recurrence, and patient outcomes were summarized. Results Seventeen patients were included in study analyses. The median PFS from completion of paclitaxel/carboplatin was 8.0 months (95% CI: 4.5-13.6 months). At the time of recurrence, all 17 patients were treated with doxorubicin as second-line therapy. No patient achieved objective response of stable disease. The median PFS of this cohort following doxorubicin treatment was 2.1 months (95% CI: 0.95-2.7) months. Median OS was 5.8 months (95% CI: 1.0-15.0 months). There is only one patient still alive; her median follow-up time is 49.4 months. Predominant doxorubicin-related grade 2 toxicities included nausea/vomiting (18.8%), fatigue (18.8%), and neutropenia (12.5%). No grade 3 or 4 toxicities occurred. Conclusions Among patients with advanced endometrial carcinoma who had received adjuvant paclitaxel/carboplatin, treatment with doxorubicin at time of disease recurrence failed to achieve any objective responses and was associated with a very short (2 months) time to

    Key points Older pregnant women have a greater risk of operative delivery, still birth and post‐term induction.This suggests that maternal age can influence the timing of birth and processes of parturition.We have found that increasing maternal age in C57BL/6J mice is associated with prolongation of gestation and length of labour.Older pregnant mice also had delayed progesterone withdrawal and impaired myometrial function.Uterine ageing and labour dysfunction should be investigated further in older primigravid women. Abstract Advanced maternal age (≥35 years) is associated with increased rates of operative delivery, stillbirth and post‐term labour induction. The physiological causes remain uncertain, although impaired myometrial function has been implicated. To investigate the hypothesis that maternal age directly influences successful parturition, we assessed the timing of birth and fetal outcome in pregnant C57BL/6J mice at 3 months (young) and 5 months (intermediate) vs. 8 months (older) of age using infrared video recording. Serum progesterone profiles, myometrium and cervix function, and mitochondrial electron transport chain complex enzymatic activities were also examined. Older pregnant mice had a longer mean gestation and labour duration (P < 0.001), as well as reduced litter size (P < 0.01) vs. 3‐month‐old mice. Older mice did not exhibit the same decline in serum progesterone concentrations as younger mice. Cervical tissues from older mice were more distensible than younger mice (P < 0.05). Oxytocin receptor and connexin‐43 mRNA expression were reduced in the myometrium from 8‐month‐old vs. 3‐month‐old mice (P < 0.05 and P < 0.01 respectively) in tandem with more frequent but shorter duration spontaneous myometrial contractions (P < 0.05) and an attenuated contractile response to oxytocin. Myometrial mitochondrial copy number was reduced in older mice, although there were no age‐induced changes to the enzymatic

    An 81-year-old man was referred to our hospital because of a right renal tumor with vena cava thrombus and multiple lung metastases that were detected by computed tomography (CT) scan during evaluation of respiratory discomfort. We started medical treatment with sunitinib at a dose of 50 mg daily in a 2-week-on, 1-week-off schedule after confirming clear cell renal cell carcinoma by tumor biopsy. After 2-week sunitinib treatment, thrombocytopenia continued and platelet count decreased to 1.8×10(9)/l at day 11 after stopping sunitinib. We needed to administer a total of 60 units platelet transfusion because of persistent thrombocytopenia. Bone marrow aspiration did not reveal myelosuppression or carcinoma invasion to bone marrow. Under the clinical diagnosis of drug-induced thrombocytopenia secondary to sunitinib, we started immunoglobulin therapy at day 23 after stopping sunitinib. Platelet count returned to normal 10 days after starting immunoglobulin. The patient developed exacerbating lung metastasis and carcinomatous lymphangiosis during subsequent course and died of renal cell carcinoma 79 days after starting sunitinib. Thrombocytopenia after sunitinib therapy is often encountered but prolonged thrombocytopenia is rare after stopping sunitinib. This case suggests that immunoglobulin therapy is effective for drug-induced prolonged thrombocytopenia through immunological mechanism.

    Objective The objective of this study was to evaluate the clinical benefits of routine squamous cell carcinoma antigen (SCC-Ag) monitoring of patients with locally advanced cervical squamous cell carcinoma treated with radiation or chemoradiation. Methods A total of 53 patients with recurrent cervical squamous cell carcinoma treated with radiotherapy or chemoradiation were enrolled in this study. A retrospective review of medical records was conducted. The role of routine monitoring of serum SCC-Ag was evaluated in terms of cost effectiveness and effect on survival after diagnosis of recurrence. Results Serum SCC-Ag abnormality (≥2.5 ng/mL) was observed in 62.3% of patients when recurrent disease was diagnosed. The first indicator of relapse was abnormal serum SCC-Ag level in 21 patients (39.6%), 10 of whom had asymptomatic recurrent disease amenable to salvage therapy. Adding SCC-Ag measurement to the basic follow up protocol improved the sensitivity for detecting recurrence (The sensitivity of the basic protocol vs. addition of SCC-Ag: 49.1% vs. 88.7%, P<0.001). Twenty-three patients who were candidates for salvage therapy with curative intent showed better survival compared with those who were not candidates for therapy (5-year survival: 36.6% vs. 0%, P=0.012). Conclusion Surveillance with routine serum SCC-Ag monitoring can better detect asymptomatic recurrent disease that is potentially amenable to salvage therapy with curative intent. Early diagnosis of recurrent disease that can be treated with salvage therapy may lead to better survival. PMID:27462593

    The presence of ectopic decidua in pelvic lymph nodes from patients with squamous carcinoma of the cervix makes evaluation for metastatic disease difficult due to the light microscopic similarity between decidua and sheets of squamous epithelial cells. A patient is present in whom decidualized endometriosis was intimately associated with metastatic moderately differentiate squamous carcinoma in a single pelvic lymph node. This phenomenon afforded an excellent opportunity to study the unique morphologic features that distinguish these two entities. A prior report of this kind was not found. In the absence of obvious squamous differentiation (i.e., intercellular bridges, dyskeratosis, and keratin "pearl" formation), as is frequently the case with squamous carcinoma of the cervix, the light microscopic features that are most useful in distinguishing squamous carcinoma from decidua include the presence of well-defined nests of cohesive cells, nuclear hyperchromasia, and cellular pleomorphism.

    Purpose To evaluate tumor shrinking kinetics in order to implement image-guided brachytherapy (IGBT) for the treatment of patients with cervix cancer. Material and methods This study has prospectively evaluated tumor shrinking kinetics of thirteen patients with uterine cervix cancer treated with combined chemoradiation. Four high dose rate brachytherapy fractions were delivered during the course of pelvic external beam radiation therapy (EBRT). Magnetic resonance imaging (MRI) exams were acquired at diagnosis (D), first (B1), and third (B3) brachytherapy fractions. Target volumes (GTV and HR-CTV) were calculated by both the ellipsoid formula (VE) and MRI contouring (VC), which were defined by a consensus between at least two radiation oncologists and a pelvic expert radiologist. Results Most enrolled patients had squamous cell carcinoma and FIGO stage IIB disease, and initiated brachytherapy after the third week of pelvic external beam radiation. Gross tumor volume volume reduction from diagnostic MRI to B1 represented 61.9% and 75.2% of the initial volume, when measured by VE and VC, respectively. Only a modest volume reduction (15-20%) was observed from B1 to B3. Conclusions The most expressive tumor shrinking occurred in the first three weeks of oncological treatment and was in accordance with gynecological examination. These findings may help in IGBT implementation. PMID:27648083

    Purpose: The aim of this study was to evaluate the efficacy of adjuvant radiotherapy after transoral laser microsurgery for advanced recurrent head-and-neck squamous cell carcinoma (HNSCC). Patients and Methods: Between 1988 and 2000, 37 patients with advanced local recurrences (23 local and 14 locoregional recurrences) of HNSCC without distant metastases were treated in curative intent with organ-preserving transoral laser microsurgery and adjuvant radiotherapy (before 1994 split-course radiotherapy with carboplatinum, after 1994 conventional radiotherapy). Initial therapy of the primary (8.1% oral cavity, 35.1% oropharynx, 13.5% hypopharynx, and 43.3% larynx) before relapse was organ-preserving transoral laser microsurgery without any adjuvant therapy. Results: After a median follow-up of 124 months, the 5-year overall survival rate was 21.3%, the loco-regional control rate 48.3%, respectively. In multivariate analysis, stage of original primary tumor (Stage I/II vs. Stage III/IV), and patient age (<58 years vs. {>=}58 years) showed statistically significant impact on prognosis. In laryngeal cancer, larynx preservation rate after treatment for recurrent tumor was 50% during follow-up. Conclusion: Our data show that organ-preserving transoral laser microsurgery followed by adjuvant radiotherapy is a curative option for patients who have advanced recurrence after transoral laser surgery and is an alternative to radical treatment.

    Objective: To determine the clinical efficacy and toxicity of pemetrexed combined with low-dose cisplatin (CDDP) concurrent with late-course accelerated hyperfractionated (LCAF) intensity-modulated radiation therapy (IMRT) in patients with inoperable locally advanced oesophageal squamous cell carcinoma (ESCC). Methods: Patients with locally advanced ESCC (less than or equal to 75 years of age, clinical stages IIB–IVA and Karnofsky performance status ≥70) were enrolled into the study. A target group size of 22 was projected based on the estimation that 2-year overall survival (OS) would increase from 20% to 40%. Patients were treated with pemetrexed, low-dose CDDP and LCAF IMRT concurrently. The main objective of the study was for a 2-year OS, and the secondary objectives were progression-free survival (PFS), objective response, locoregional failure rate, and acute and late toxicities. Results: 25 patients were recruited from October 2008 to July 2011. The median OS was 21 months, with 2- and 5-year OS rates of 44% and 44%, respectively. The median PFS was 18.2 months. The objective response rate was 96% (24/25), with 11 complete responses and 13 partial responses. The locoregional failure rate was 16%. Grades 4 and 5 acute toxicity rates were 8% and 4%, respectively, while no Grade 3 or greater late toxicity was observed. Conclusion: The findings of this Phase II study indicated that the therapeutic regimen appears to achieve an excellent response rate and favourable survival for locally advanced ESCC. However, the severe acute side effects should be considered cautiously in further studies. Advances in knowledge: To our knowledge, this is the first study that introduced pemetrexed and low-dose CDDP combined with LCAF IMRT to treat locally advanced ESCC. The 5-year OS rate was as high as 44%, which was more favourable than other studies. PMID:24666012

    Sorafenib is the standard systemic treatment for patients with advanced hepatocellular carcinoma (HCC); however, its therapeutic value in patients with HCC following resection remains controversial. The current retrospective study was undertaken to assess the effects of sorafenib treatment following surgical resection in patients with advanced HCC disease who were at a high risk for recurrence. Between July 2010 and July 2013, a consecutive cohort of 42 patients with advanced HCC and at a high risk of recurrence (i.e., those with portal vein tumor thrombosis, adjacent organ involvement or tumor rupture) who underwent resection were analyzed. The patients were categorized into the sorafenib group (n=14) or the best supportive care (BSC) group (n=28). Although the histological grade, Barcelona Clinic Liver Cancer Stage, tumor size, nodule number and proportion of patients with high serum α-fetoprotein levels were comparable between the sorafenib and BSC groups, those receiving sorafenib following resection had significantly longer disease-free survival (DFS) of 5.2 months [95% confidence interval (CI), 1.2–9.2 months] compared with the BSC group [1.8 months (95% CI, 0.6–3.0 months)]. No differences in overall survival were noted between the groups. Furthermore, no drug-related adverse events resulted in discontinuation of sorafenib therapy. Univariate log-rank analysis revealed that sorafenib treatment (P=0.002) and treatment prior to resection (P=0.012) were significantly associated with longer DFS; however, sorafenib therapy (P=0.027) and tumor size (P=0.028) were associated with longer DFS by multivariate analysis. Furthermore, sorafenib was well-tolerated and improved DFS in patients with advanced HCC who underwent hepatic resection. Thus, tumor resection followed by sorafenib therapy may represent an effective therapeutic strategy for patients with advanced HCC. This possibility should be confirmed in larger, multicenter studies. PMID:28356989

    Purpose The purpose of this study was to evaluate the effectiveness and toxicity of capecitabine (C) chemotherapy regimen with or without (w/o) docetaxel (D) in patients with advanced urothelial carcinoma (UC). Results Clinical benefit rate were similar in two arms (C arm vs DC arm: 38.9% vs 45.5%, p = 0.411). There were two cases achieved partial response in DC arm. In C arm, the median PFS was 3.0 months (95% CI 2.5–3.5 months) and median OS was 11.3 months (95% CI 8.6–14.1 months). In DC arm, the median PFS was 2.2 months (95% CI 1.7–2.7 months) and median OS was 18 months (95% CI 6.8–29.9 months). Adverse events were mostly acceptable, including myelosuppession, hand-foot syndrome and mucositis. Anemia and leukopenia was found more in the DC arm than in the C arm. Materials and Methods This is a one-center, observational, retrospective study. From April 2009 to March 2015, a total of 29 patients with metastatic UC were included in the study. Survivals, response rates and toxicities were collected retrospectively. Conclusions The result showed the activity and toxicity of C w/o D. As DC treatment did not reveal better outcome, C or D single-agent might be an option in platinum-failed patients with advanced urothelial carcinoma. Further clinical trials are warranted.

    Purpose: To compare volumetric modulated arc radiotherapy (VMAT) technique with fixed-gantry intensity-modulated radiotherapy (IMRT) technique for locally advanced laryngeal carcinoma. Methods: CT datasets of eleven patients were included. Dual-arc VMAT and 7-field IMRT plans, which were created based on the Eclipse treatment planning system, were compared in terms of dose-volume parameters, conformity index (CI) and homogeneity index (HI) of planning target volume (PTV), as well as organ-at-risk (OAR) sparing, planning time, monitor units (MUs) and delivery time. Results: Compared with the IMRT plans, the VMAT plans provided lower D2% and better CI/HI for the high-risk PTV (PTV1), and provided better CI and comparable HI for the low-risk PTV (PTV2). Concerning the OAR sparing, the VMAT plans demonstrated significantly lower Dmax of the spinal cord (planning OAR volume, PRV) and brainstem (PRV), as well as lower Dmean and V30Gy of the right parotid. No significant differences were observed between the two plans concerning the doses delivered to the thyroid, carotid, oral cavity and left parotid. Moreover, the VMAT planning (147 ± 18 min) consumed 213% more time than the IMRT planning (48 ± 10 min). The MUs of the VMAT plans (556 ± 52) were 64% less than those of the IMRT plans (1684 ± 409), and the average delivery time (2.1 ± 0.1 min) was 66% less than that of the IMRT plans (6.3 ± 0.7 min). Conclusion: Compared with the IMRT technique, the VMAT technique can achieve superior target dose distribution and better sparing of the spinal cord, brainstem and right parotid, with less MUs and less delivery time. It is recommended for the radiotherapy of locally advanced laryngeal carcinoma.

    Purpose: The outcome of a prospective case series of 47 patients with newly diagnosed resectable locoregionally advanced oropharyngeal squamous cell carcinoma treated with platinum-based induction-concurrent chemoradiotherapy (IC/CCRT) was compared with the outcome of 47 matched historical control patients treated with surgery and postoperative RT. Methods and Materials: A total of 47 control patients with locoregionally advanced oropharyngeal squamous cell carcinoma were identified from review of a prospectively compiled comprehensive computerized head-and-neck cancer database and were matched with a prospective case series of patients undergoing IC/CCRT by disease stage, nodal status, gender, and age ({+-}5 years). The IC/CCRT regimen consisted of one cycle of induction chemotherapy followed by conventionally fractionated RT to a total dose of 66-70 Gy concomitantly with two cycles of chemotherapy. Each cycle of chemotherapy consisted of cisplatinum, 100 mg/m{sup 2}, and a continuous infusion of 5-fluorouracil, 1,000 mg/m{sup 2}/d for 5 days. The survival analysis was performed using Kaplan-Meier estimates. Matched-pair survival was compared using the Cox proportional hazards model. Results: No significant difference was found in the overall survival or progression-free survival rates between the two groups. The matched analysis of survival did not show a statistically significant greater hazard ratio for overall death (hazard ratio, 1.35; 95% confidence interval, 0.65-2.80; p = .415) or progression (hazard ratio, 1.44; 95% confidence interval, 0.72-2.87; p = .301) for patients undergoing IC/CCRT. Conclusion: Although the sample size was small and not randomized, this matched-pair comparison between a prospective case series and a historical cohort treated at the same institution showed that the efficacy of IC/CCRT with salvage surgery is as good as primary surgical resection and postoperative RT.

    Treatment with cloprostenol, a prostaglandin synthetic analogue, was evaluated in five queens with open-cervix pyometra. Cloprostenol was administered (5 μg/kg body weight SC) on 3 consecutive days and amoxicillin (20 mg/kg body weight IM) on 7 consecutive days. Transient post-injection reactions caused by cloprostenol administration included diarrhea, vomiting and vocalizations. Reactions began as quickly as 10 mins after cloprostenol administration and lasted as long as 30 mins. All queens improved clinically after cloprostenol treatment and remained healthy until the end of the study, 1 year after treatment. All queens resumed normal estrous cycles without further treatment and two (40%) delivered a normal litter. In conclusion, use of cloprostenol is an acceptable treatment for open-cervix pyometra in queens.

    A comparison was made between four methods of ripening the unfavourable cervix (extra-amniotic prostaglandin E2 gel, oral prostaglandin E2, intravaginal prostaglandin E2 and intravenous oxytocin) in a clinical trial involving 60 primigravidae. In all groups there was an improvement in cervical status. This was significantly greater in those patients who received extra-amniotic prostaglandin gel and they also showed significant decreases in the mean induction-delivery interval and in the incidence of Caesarean section.

    Background To find prognostic biomarkers in pretreatment dynamic contrast-enhanced MRI (DCE-MRI) water-exchange-modified (WX) kinetic parameters for advanced hepatocellular carcinoma (HCC) treated with antiangiogenic monotherapy. Methods Twenty patients with advanced HCC underwent DCE-MRI and were subsequently treated with sunitinib. Pretreatment DCE-MRI data on advanced HCC were analyzed using five different WX kinetic models: the Tofts-Kety (WX-TK), extended TK (WX-ETK), two compartment exchange, adiabatic approximation to tissue homogeneity (WX-AATH), and distributed parameter (WX-DP) models. The total hepatic blood flow, arterial flow fraction (γ), arterial blood flow (BFA), portal blood flow, blood volume, mean transit time, permeability-surface area product, fractional interstitial volume (vI), extraction fraction, mean intracellular water molecule lifetime (τC), and fractional intracellular volume (vC) were calculated. After receiver operating characteristic analysis with leave-one-out cross-validation, individual parameters for each model were assessed in terms of 1-year-survival (1YS) discrimination using Kaplan-Meier analysis, and association with overall survival (OS) using univariate Cox regression analysis with permutation testing. Results The WX-TK-model-derived γ (P = 0.022) and vI (P = 0.010), and WX-ETK-model-derived τC (P = 0.023) and vC (P = 0.042) were statistically significant prognostic biomarkers for 1YS. Increase in the WX-DP-model-derived BFA (P = 0.025) and decrease in the WX-TK, WX-ETK, WX-AATH, and WX-DP-model-derived vC (P = 0.034, P = 0.038, P = 0.028, P = 0.041, respectively) were significantly associated with an increase in OS. Conclusions The WX-ETK-model-derived vC was an effective prognostic biomarker for advanced HCC treated with sunitinib. PMID:26366997

    The present study aimed to detect the expression of metastasis associated lung adenocarcinoma transcript 1 (MALAT1) and microRNA (miR)-619-5p in colorectal carcinoma (CRC), and to evaluate the significance of MALAT1 and miR-619-5p expression in the clinical diagnosis and prognosis of CRC. Quantitative polymerase chain reaction was used to detect MALAT1 and miR-619-5p expression in 120 colorectal carcinoma and 120 adjacent normal tissue samples. The expression levels of MALAT1 and miR-619-5p were significantly different between colorectal carcinoma and adjacent normal tissues (P<0.05). MALAT1 exhibited an average 2.52-fold increase in colorectal adenoma when compared with adjacent normal tissues, while miR-619-5p exhibited an average 5.79-fold decrease in colorectal adenoma when compared with adjacent normal tissues. There was a significant difference between the MALAT1 expression in CRC tissues obtained from men and women (P=0.027), and in tumor-node-metastasis (TNM) stage II and stage III lesions (P=0.019). MALAT1 expression was associated with lymphovascular invasion (P=0.047) and perineural invasion (P=0.012). In addition, miR-619-5p expression was also significantly different between men and women (P=0.032), and between TNM stage II and stage III lesions (P=0.012). miR-619-5p expression was also associated with lymphovascular invasion (P=0.023) and perineural invasion (P=0.009). Patients with high expression of MALAT1 and low expression of miR-619-5p demonstrated significantly shorter disease-free survival (DFS) (P=0.002) and overall survival (OS) times (P=0.004) compared with patients with low MALAT1 expression and high miR-619-5p expression. Patients with perineural invasion demonstrated significantly shorter DFS (P=0.001) and OS times (P=0.003) compared with patients without perineural invasion. In addition, there was a negative correlation between MALAT1 expression and miR-619-5p expression (r=−0.415, P=0.004) in CRC tissues. In conclusion, MALAT1 and mi

    Purpose. To assess the volume of locally advanced tumors of the oral cavity and the oropharynx before and after intra-arterial (i.a.) chemotherapy by means of computed tomography and to compare these data with clinically determined treatment response of the same patient population. Methods. Eighty-eight patients with histologically proven, advanced carcinoma of the oral cavity and/or the oropharynx (local tumor stages T3/4) received neoadjuvant i.a. chemotherapy with cisplatin as part of a multimodal therapeutic regimen, comprising (1) local chemotherapy, (2) surgery, and (3) combined radio-chemotherapy. Three weeks after the intervention, residual disease was evaluated radiologically by measurement of the tumor volume and clinically by inspection and palpation of the primary tumor according to WHO criteria. Results. Comparison of treatment response according to radiological and clinical criteria respectively revealed complete remission in 5% vs. 8% (p < 0.05), partial remission in 30% vs. 31%, stable disease in 61% vs. 58%, and tumor progression in 5% vs. 2%. Conclusion. Radiological volumetry and clinical evaluation found comparable response rates after local chemotherapy. However, in patients with good response after local treatment, volumetric measurement with CT may help to distinguish between partial and complete remission. Thus, radiological tumor volumetry provides precise and differentiated information about tumor response and should be used as an additional tool in treatment monitoring after local chemotherapy.

    The present study evaluated the clinical and prognostic value of neutrophil-to-lymphocyte ratio (NLR) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) treated with definitive chemoradiotherapy (dCRT). A total of 517 patients with ESCC were enrolled and analysed retrospectively. The NLR was calculated at three time points: baseline, post-treatment, and at the time of tumor progression. Elevated NLR was defined as a ratio ≥5. High NLR at baseline was present in 204 (39%) patients and was significantly correlated with larger tumour size, advanced TNM stage, worse ECOG performance status, and dCRT response (p < 0.05). At a median follow-up of 17 months, patients with higher NLR at baseline had poorer progression-free survival (PFS) and overall survival (OS). On multivariate analysis, elevated NLR at baseline was independently associated with PFS and OS (HR = 1.529, p < 0.001 for PFS; HR = 1.856, p < 0.001 for OS). In addition, patients with high pre- and post-treatment NLR demonstrated worse clinical outcomes than other groups. Our results suggest that NLR is an independent prognostic indicator for patients with ESCC undergoing dCRT and changes in NLR level with treatment may indicate therapeutic benefit. PMID:28195186

    Nasopharyngeal carcinoma (NPC) is highly incident in southern China. Metastasis is the major cause of death in NPC patients. Concurrent chemoradiotherapy (CCRT) has been accepted as standard in the treatment of patients with locoregionally advanced nasopharyngeal carcinoma (NPC). However, induction chemotherapy (IC) also has benefits in this disease, especially in the patients with certain high-risk factors such as bulky and/or extensive nodal disease. It has been presented that adding IC to CCRT might be a reasonable approach and need more work to confirm. The optimal chemotherapeutic regimen combined with radiotherapy has not been determined so far. It is important to explore high effective and low toxic chemotherapy for the patients. In the multicenter prospective study, 223 patients with locoregionally advanced untreated NPC were randomized into experimental group and control group. The patients received two cycles of induction chemotherapy (IC) with docetaxel (DOC) plus nedaplatin (NDP) in experimental group every 3 weeks, followed by IMRT concurrent with weekly NDP for six cycles, and NDP was replaced by cisplatin (CDDP) in control group. More patients in experimental group could receive full courses of IC and concurrent chemoradiotherapy (CCRT) (P=0.013). There was no significant difference between the two groups in the percentage of reduction of GTVnx and GTVnd after IC (P=0.207 and P=0.107) and CR rate three months after completion of chemoradiotherapy (P=0.565 and P=0.738). With a mean follow-up of 35.1 months, no statistically significant difference in the 3-year OS, LRFS, RRFS, DMFS, and PFS was found. During IC, more patients suffered vomiting in control group (P=0.001). During CCRT, grade 3/4 neutropenia/thrombocytopenia were more common in experimental group (P=0.028 and P=0.035); whereas, severe anemia and vomiting were more common in control group (P=0.0001 and P=0.023). In conclusions, patients with locoregionally advanced NPC showed good

    The treatment of metastatic renal cell carcinoma (mRCC) has markedly improved over the last few years with the introduction of several targeted agents in clinical practice. Nevertheless, either primary or secondary resistance to inhibition of VEGF and mTOR pathways has limited the clinical benefit of these systemic treatments. Recently, a better understanding of the involvement of MET and its ligand HGF in many biological processes made this signaling pathway an attractive therapeutic target in oncology, particularly in mRCC. Herein, we review the development of cabozantinib, a recently approved inhibitor of multiple tyrosine kinase receptors, including MET, VEGFRs, and AXL, which has proven to increase progression-free survival and overall survival when compared to everolimus in mRCC patients who had progressed after VEGFR-targeted therapy. Finally, we discuss the potential role of cabozantinib within the current treatment landscape for mRCC. PMID:27462141

    Background Tumor protein (P53) and heat shock protein 70 (HSP70) play key roles in chronic liver diseases. This study aimed to characterize P53 and HSP70 expression in chronic hepatitis (CH), liver cirrhosis (LC), early and advanced HCC, and to analyze their diagnostic value in hepatocellular carcinoma (HCC). Material/Methods Immunohistochemical staining was conducted to evaluate the expression of P53 and HSP70 in 200 human liver tissue specimens, with advanced HCC (n=80), early HCC (n=30), CH (n=30), LC (n=30), and Controls (n=30). Results P53 expression levels were lower in LC than those of HCC, but remained on par with those of CH and Controls. HSP70 expression levels were higher in HCC than those of LC, CH, and Controls. The sensitivity and specificity for HCC diagnosis were: 50.9% and 98.9% for P53, and 78.2 and 77.8% for HSP70, respectively. The sensitivity and specificity of different combinations were: 95.5% and 85.5% with either P53 or HSP70 being positive, and 33.6% and 98.9% if both were positive. Among the differentiation stages marked low, intermediate, and high in HCC, the P53 positive rate was higher in the low than in the intermediate, which was higher than that in the high. HSP70 positive rate was higher in the low and the intermediate than in the high, but no obvious changes were found between the low and the intermediate. Conclusions P53 and HSP70 could be potential biomarkers for HCC diagnosis, and proper combinations of these 2 markers could improve diagnostic accuracy. PMID:26494212

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease.
