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

    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.

    Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tomography scan. The patient was treated with hormonal therapy, but thereafter, specimens from a transurethral resection of the prostate (TURP) were found to be composed of three histologically distinct elements: ASC, SC and adenocarcinoma. The level of p53 was evaluated by immunohistochemistry in detail, and it was found that this was significantly increased in the TURP samples compared with the needle biopsy samples. The abnormal level of p53 was likely associated with the prognosis of the patient; the patient succumbed to prostate carcinoma two months after the confirmation of the diagnosis. PMID:25295118

    Sixteen women with adenocarcinoma of the cervical stump were treated over a 15-year period. The median survivals of 40 months for stage IB and 17 months for stages II and III were significantly worse compared with those for patients treated for cervical adenocarcinoma of the intact uterus or squamous carcinoma of the cervical stump. The poor results were due to both local and distant failure. Implications regarding tumor radiosensitivity and adjuvant therapy in these high-risk patients are discussed.

    Neoadjuvant chemotherapy (NACT) for advanced cervical cancer in pregnancy has been shown to increase operability and be effective against spread of disease. In all reported cases of advanced disease, residual tumour has been found at surgery following NACT. We present a case of a 27-year old diagnosed with stage IB2 adenosquamous cervical carcinoma at 19-weeks' gestation who was treated with NACT. Following caesarean section and radical hysterectomy, histopathology showed no evidence of residual tumour in the cervix and negative pelvic lymph nodes. PMID:25470742

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    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.

    Uterine cervical adenocarcinoma (ADC) has been increasing in its prevalence world widely despite the decrease of squamous cell carcinoma (SCC). It comprises nearly 20-25% of the all cervical malignancy in developed countries. The worse biological behavior had been reported in patients with intermediate- and high risk factors after surgery, and in advanced stage over Ⅲ, radiotherapy (RT) alone and concurrent chemo-radiotherapy (CCRT) with cisplatin was not always effective. As for chemotherapy (CT), the induction CT has not established, as well. Further molecular targeted therapy (MTT) has been studied. The targets of oncogenic driver mutations were vascular endothelial growth factor (VEGF) in SCC, or tyrosine kinase (TK) of endothelial growth factor receptor 2 (EGFR2, Her2/neu)-Ras-MAPK-ERK pathway. Bevacizumab (Bev, anti-VEGF monoclonal antibody) is considered as one of key agent with paclitaxel and carboplatin in SCC, but not for ADC. This article focuses on up-to-date knowledge of biology and possible specific therapeutic directions to explore in the management of cervical ADC. PMID:27198186

    AIMS: To examine neuroendocrine differentiation, as shown by chromogranin A (CGA) expression, in cervical carcinomas. METHODS: Sixty seven cervical carcinomas were studied and were classified as adenocarcinomas, adenosquamous carcinomas or squamous cell carcinomas based on the assessment of haematoxylin and eosin staining and stains for mucin. Where features of glandular differentiation were identified, sections were also stained for evidence of intestinal type mucin. CGA immunostaining was done and the results were graded on a three point scale: 0, + (1-5% of cells positive) and ++ (> 5% of cells positive). These findings were then analysed with respect to lymph node status, tumour differentiation and clinical outcome. RESULTS: There were 32 adenocarcinomas, 18 adenosquamous carcinomas and 17 squamous cell carcinomas. Positive staining was seen in 14 (20.9%) cases, of which four were strongly positive. All but one case were either adenocarcinomas or adenosquamous carcinomas. There was a trend for CGA positivity to be related to intestinal differentiation but this failed to reach statistical significance. No correlation could be demonstrated between CGA staining and lymph node status, tumour differentiation and clinical outcome. CONCLUSIONS: Neuroendocrine differentiation is common in cervical carcinomas where there is evidence of glandular differentiation. Whilst the numbers in this study are relatively small, the presence of neuroendocrine cells in otherwise typical carcinomas does not seem to have any association with clinical behaviour.

    FDG avid uterine cervical masses are most commonly due to primary cervical carcinoma; however, history and differential diagnoses are critical when interpreting FDG PET/CT studies. A 51-year-old woman with newly diagnosed moderately differentiated adenocarcinoma of the rectum underwent FDG PET/CT for staging, which revealed the hypermetabolic primary rectal tumor and nodal metastases. Additionally, FDG avid focus in the anterior cervix without a CT correlate was present. Cervical metastasis was suspected, and further evaluation with MRI and histopathologic correlation was recommended, which confirmed cervical metastasis. This case illustrates an unusual case of FDG-avid cervical metastasis from rectal adenocarcinoma. PMID:27276209

    Lung adenosquamous carcinoma is a particular subtype of non-small cell lung carcinoma that is defined by the coexistence of adenocarcinoma and squamous cell carcinoma components. The aim of this study was to assess the mutational profile in each component of 16 adenosquamous carcinoma samples from a Caucasian population by a combination of next generation sequencing using the cancer hotspot panel as well as the colon and lung cancer panel and FISH. Identified mutations were confirmed by Sanger sequencing of DNA from cancer cells of each component collected by Laser Capture microdissection. Mutations typical for adenocarcinoma as well as squamous cell carcinoma were identified. Driver mutations were predominantly in the trunk suggesting a monoclonal origin of adenosquamous carcinoma. Most remarkably, EGFR mutations and mutations in the PI3K signaling pathway, which accounted for 30% and 25% of tumors respectively, were more prevalent while KRAS mutations were less prevalent than expected for a Caucasian population. Surprisingly, expression of classifier miR-205 was intermediate between that of classical adenocarcinoma and squamous cell carcinoma suggesting that adenosquamous carcinoma is a transitional stage between these tumor types. The high prevalence of therapy-relevant targets opens new options of therapeutic intervention for adenosquamous carcinoma patients. PMID:26068980

    Latent transforming growth factor-beta-1 binding protein-2 (LTBP-2) is a member of the fibrillin/LTBP super family of extracellular matrix proteins, found to be overexpressed in certain malignant tumors. However, the clinical significance and biological role of LTBP-2 in cervical adenocarcinoma has remains unclear. We found that the expression of LTBP2 was higher in cervical adenocarcinoma than in normal cervical epithelial tissue as assessed by immunohistochemistry. Expression of LTBP2 is related to clinical stage, cervical tumor size, depth of cervical stromal invasion and lymph node metastasis. Knockdown of LTBP2 expression can inhibit the proliferation and migration of HeLa cells. Moreover, LTBP2 knockdown affected multiple tumor-related pathway genes including: the MAPK signaling pathway, the PI3K-AKT signaling pathway, receptor tyrosine kinase signaling and the P53 pathway. Taken together, this work suggests that LTBP2 may promote the development of cervical adenocarcinoma and serve as a prognostic factor in the clinical evaluation of patients with cervical adenocarcinoma. Our findings provide a new strategy for the diagnosis and treatment of cervical adenocarcinoma. PMID:26279753

    We studied a methods of assessment of a connective tissue of cervix in terms of specific volume of fibrous component and an optical density of staining of connective tissue fibers in the stroma of squamous cancer and cervix adenocarcinoma. An absorption spectra of blood plasma of the patients suffering from squamous cancer and cervix adenocarcinoma both before the surgery and in postsurgical periods were obtained. Linear dichroism measurements transmittance in polarized light at different orientations of the polarization plane relative to the direction of the dominant orientation in the structure of the sample of biotissues of stroma of squamous cancer and cervix adenocarcinoma were carried. Results of the investigation of the tumor tissues showed that the magnitude of the linear dichroism Δ is insignificant in the researched spectral range λ=280-840 nm and specific regularities in its change observed short-wave ranges.

    Esophageal adenocarcinoma arising from ectopic gastric mucosa (EGM) is extremely rare. We describe here two Japanese patients with adenocarcinoma of the cervical esophagus arising from EGM. Case 1 is a 62-year-old man who had slightly red EGM in the cervical esophagus on upper gastrointestinal endoscopy (UGE). Because the biopsy showed atypical glands that were suspicious for adenocarcinoma, endoscopic submucosal dissection was performed. Histopathological examination revealed that the lesion was a well-differentiated adenocarcinoma (pT1a MM). Lymphovascular invasion was absent, and the margins were free from carcinoma. Case 2 is a 57-year-old man who had an elevated lesion with a bleeding tendency in an area of EGM in the cervical esophagus on UGE. Adenocarcinoma was diagnosed in the biopsy. Because of the presence of enlarged lymph nodes (#106recL), preoperative chemoradiotherapy was performed to reduce the size of the adenocarcinoma and lymph nodes prior to resection of the cervical esophagus and reconstruction with free jejunal grafts. Histopathological examination revealed moderately differentiated adenocarcinoma (0-I, pT2N1M0, pStage II). In both cases, adenocarcinoma was surrounded by EGM, which led to the diagnosis of EGM-derived esophageal adenocarcinoma. Here, we report its immunohistochemical characteristics in the present cases and discuss the histogenesis. PMID:26476962

    Adenocarcinomas exhibiting gastric differentiation represent a recently described and uncommon subtype of non-human papillomavirus (HPV)-related cervical adenocarcinoma. They comprise a spectrum from a well-differentiated variant (adenoma malignum/mucinous variant of minimal deviation adenocarcinoma) to a more poorly differentiated overtly malignant form, generally referred to as gastric-type adenocarcinoma. Rarely, such tumors have also been described as primary vaginal neoplasms. Gastric-type adenocarcinomas exhibit considerable morphologic overlap with adenocarcinomas originating outside the female genital tract, especially mucinous adenocarcinomas arising in the pancreas and biliary tract. Moreover, they often metastasize to unusual sites, such as the ovary and peritoneum/omentum, where they can be mistaken for metastatic adenocarcinomas from other, nongynecologic sites. There is little information regarding the immunophenotype of gastric-type adenocarcinomas, and knowledge of this is important to aid in the distinction from other adenocarcinomas. In this study, we undertook a detailed immunohistochemical analysis of a large series of cervical (n=45) and vaginal (n=2) gastric-type adenocarcinomas. Markers included were cytokeratin (CK)7, CK20, CDX2, carcinoembryonic antigen, CA125, CA19.9, p16, estrogen receptor, progesterone receptor, MUC6, PAX8, PAX2, p53, hepatocyte nuclear factor 1 beta, carbonic anhydrase IX, human epidermal receptor 2 (HER2), and mismatch repair (MMR) proteins. All markers were classified as negative, focal (<50% of tumor cells positive), or diffuse (≥50% tumor cells positive) except for p53 (classified as "wild-type" or "mutation-type"), HER2 (scored using the College of American Pathologists guidelines for gastric carcinomas), and MMR proteins (categorized as retained or lost). There was positive staining with CK7 (47/47-45 diffuse, 2 focal), MUC6 (17/21-6 diffuse, 11 focal), carcinoembryonic antigen (25/31-12 diffuse, 13 focal

    Background A role of Chlamydia trachomatis in HPV-induced cervical carcinogenesis has been reported for cervical cancer but studies on cervical adenocarcinoma are limited. Methods A total of 1,553 cervical smears taken up to 26 years before diagnosis in a large population-based nested case-control study of cervical adenocarcinoma (AC, 132 cases with matched controls), and adenocarcinoma in situ (AIS, 159 cases with matched controls) were tested for C. trachomatis and HPV DNA by a type-specific PCR bead-based multiplex genotyping (TS-MPG) assay. Results Only 1.7% of samples were positive for C. trachomatis, with no significant differences between AC/AIS cases and controls. HPV-positivity was detected in 49.3% of C. trachomatis-negative and 65.4% C. trachomatis-positive samples, respectively. Conclusions A large prospective study did not find any risk for cervical adenocarcinoma and/or AIS conferred by C. trachomatis infection. Impact C. trachomatis appears not to be involved in cervical adenocarcinomas. PMID:27227411

    A case-control study of 480 patients with invasive cervical cancer and 797 population controls, conducted in five geographic areas in the United States, included an evaluation of the relationship of several cigarette smoking variables to cervical cancer risk. Although smoking was correlated with both age at first intercourse and number of sexual partners, a significant smoking-related risk persisted for squamous cell carcinoma after adjustment for these factors (relative risk, 1.5). Twofold excess risks were seen for those smoking 40 or more cigarettes per day and those smoking for 40 or more years. Increased risks, however, were observed only among recent and continuous smokers. In contrast to squamous cell cancer, no relationship was observed between smoking and risk of adenocarcinoma or adenosquamous carcinoma. These results suggest a causal relationship between cigarette smoking and invasive squamous cell cervical cancer, perhaps through a late-stage or promotional event, although the mechanisms of action require further elucidation.

    The relationship between negative cervical cytology reports and risk of adenocarcinoma of the cervix was evaluated in a case-control study of 113 cases and 452 controls. All cases and controls had received at least two negative cytology reports. There was no significant difference between the cases and controls in the number of negative cytology reports or in history of cervical abnormality; while a test for trend in the time since last negative cytology report was significant (P < 0.001), the estimated benefit was very modest. Although the estimates of relative protection were higher in women aged less than 35 years than in women aged 35-69 years, this difference was not statistically significant. These results suggest that cervical screening as practised in the 1970s and 1980s was much less effective in preventing adenocarcinoma than squamous carcinoma of the cervix. PMID:7710961

    2013-01-01

    Background The venom of Centruroides limpidus limpidus (Cll) is a mixture of pharmacologically active principles. The most important of these are toxic proteins that interact both selectively and specifically with different cellular targets such as ion channels. Recently, anticancer properties of the venom from other scorpion species have been described. Studies in vitro have shown that scorpion venom induces cell death, inhibits proliferation and triggers the apoptotic pathway in different cancer cell lines. Herein, after treating human cervical adenocarcinoma (HeLa) cells with Cll crude venom, their cytotoxic activity and apoptosis induction were assessed. Results Cll crude venom induced cell death in normal macrophages in a dose-dependent manner. However, through viability assays, HeLa cells showed high survival rates after exposure to Cll venom. Also, Cll venom did not induce apoptosis after performing ethidium bromide/acridine orange assays, nor was there any evidence of chromatin condensation or DNA fragmentation. Conclusions Crude Cll venom exposure was not detrimental to HeLa cell cultures. This may be partially attributable to the absence of specific HeLa cell membrane targets for molecules present in the venom of Centruroides limpidus limpidus. Although these results might discourage additional studies exploring the potential of Cll venom to treat human papilloma cervical cancer, further research is required to explore positive effects of crude Cll venom on other cancer cell lines.

    Ileal conduit urinary diversion (Bricker) is a standard surgical open procedure. The Da Vinci robot allowed precision for this surgical procedure, especially for intracorporeal suturing. Meanwhile, few reports of robot-assisted laparoscopic ileal conduit diversion (Bricker) are described in the literature. We report the case of a 69-year-old patient with a vaginal recurrence of cervical adenocarcinoma associated with vesicovaginal fistula treated by robot-assisted laparoscopic partial colpectomy and ileal conduit urinary diversion (Bricker). The robot-assisted laparoscopic procedure followed all surgical steps of the open procedure. Postoperative period was free of complications. PMID:26634161

    We report a case of 30-year-old woman with Peutz-Jeghers syndrome (PJS). Because of small intestinal obstruction, she received the small intestinal polypectomy in 2001, and the pathological diagnosis was Peutz-Jeghers polyp canceration (mucinous adenocarcinoma, infiltrating full-thickness of the intestine). The patient did not feel uncomfortable after 6 mo of chemotherapy and other management. We kept a follow-up study on her and found that she suffered from cervical cancer in 2007, with a pathological diagnosis of cervical adenosquamous carcinoma.The patient presented with typical features of PJS, but without a family history. The PJS accompanied with both small intestinal and cervical malignancies has not been reported so far in the world. PMID:19109876

    Human papillomavirus (HPV) are firmly established as the principal causative agent for cervical carcinoma. Current vaccines may provide some protection for women from cervical carcinoma linked to HPV genotype 16 and 18. This may be the best vaccine for Western women, but the geographical variation in HPV distributions may not make it the most appropriate vaccine for China or Asia. This study provided an observational, retrospective, hospital-based cross-sectional study on the distribution of HPV genotypes among 5410 women with invasive cervical cancer (ICC) or cervical intraepithelial neoplasia (CIN). Overall, the positive rates of the four HPV types included in current prophylactic vaccines were counted, the two high-risk types (HPV-16 and -18) covered by current vaccines represented 66.9% of women with squamous cancer, 55.0% with adenocarcinoma, 64.9% with adenosquamous carcinoma and 77.4% of other type ICC, as well as 59.5% of CIN III, 45.0% of CIN II and 38.1% of CIN I cases. As expected, two low-risk types (HPV-6 and -11) included in the quadrivalent vaccine did not show good coverage data. Particularly worth mentioning is the fact that the addition of HPV-52 and -58 to the vaccine cocktail would increase cancer protection in our population, potentially preventing up to beyond 16% of squamous/adenosquamous carcinoma and other type of cervical cancers, and 7.75% of adenocarcinomas. It might also potentially reduce the rate of CIN III by a further 28.6% and CIN II and I by a third. This study established the baseline for surveillance in Zhejiang Province, and provides data for further vaccine designs: a quadrivalent HPV vaccine covering HPV-16/-58/-18/-52, would be more welcome in our region in the forthcoming year compared to the currently available vaccine.

    In 1999, the National Cancer Institute issued a clinical advisory strongly touting the advantage of cisplatin-based chemoradiation (CCRT) for cervical cancer patients requiring radiation for their treatment. This study aimed to compare survival outcomes of cervical squamous cell carcinoma and adenocarcinoma before and after the advent of CCRT. Data were obtained from the Korea National Cancer Incidence Database for patients who were diagnosed with cervical cancers between 1993 and 2012. We compared survival according to histologic subtypes in cervical cancer patients diagnosed before (1993–1997), during (1998–2002), and after (2003–2012) the introduction of CCRT. A total of 80,766 patients were identified, including 64,531 (79.9%) women with squamous cell carcinomas and 7,265 (9.0%) with adenocarcinoma. With the introduction of CCRT, survival trends gradually increased in patients of both histologic subtypes with regional tumors. However, survival was significantly higher in squamous cell carcinoma than in adenocarcinoma patients regardless of treatment modalities (surgery alone, P < 0.001; surgery followed by CCRT, P < 0.001; or primary CCRT, P = 0.003). Multivariate analysis showed that adenocarcinoma was an independent negative prognostic factor for survival regardless of the time period (before CCRT, hazard ratio (HR) = 1.49; 95% confidence interval (CI), 1.37–1.62; after introduction of CCRT, HR = 1.40; 95% CI, 1.30–1.50). Although the survival of adenocarcinoma has improved after the introduction of CCRT, adenocarcinoma is still associated with worse overall survival compared to squamous cell carcinoma in the era of CCRT.

    We studied a methods of assessment of a connective tissue of cervix in terms of specific volume of fibrous component and an optical density of staining of connective tissue fibers in the stroma of squamous cancer and cervix adenocarcinoma. An absorption spectra of blood plasma of the patients suffering from squamous cancer and cervix adenocarcinoma both before the surgery and in postsurgical periods were obtained. Linear dichroism measurements transmittance in polarized light at different orientations of the polarization plane relative to the direction of the dominant orientation in the structure of the sample of biotissues of stroma of squamous cancer and cervix adenocarcinoma were carried. Results of the investigation of the tumor tissues showed that the magnitude of the linear dichroism Δ is insignificant in the researched spectral range λ=280-840 nm and specific regularities in its change observed short-wave ranges.

    Cutaneous metastasis (CM) is an uncommon manifestation of visceral malignancies. Adenosquamous carcinoma of the gallbladder is a rare variation in gallbladder carcinoma (GBC), associated with worse prognosis. We present the case of a 56-year-old woman who presented with an inflamed lump on her abdominal wall. Computed tomography (CT) revealed a large mass from the gallbladder invading the abdominal wall. She underwent liver resection with regional lymphadenectomy. Pathology analysis revealed a 12-cm pT3N0 GBC. Hospital discharge occurred at post-operative Day 20. She recurred and died 10 months after surgery. Survival after the diagnosis of CM is dismal. The present case was a diagnostic trap. First, the patient's skin lesion presented as a cutaneous abscess and biopsy revealed a squamous cell cancer. A CT scan suggested a continuous mass involving the abdominal wall. CM was only suspected during surgery when no continuity between the tumour and the abdominal wall was identified. PMID:25480835

    ABSTRACT BACKGROUND: Adenosquamous carcinoma of the pancreas (ASCAP) is a rare histologic type of pancreatic carcinoma that constitutes 1% to 4% of all pancreatic exocrine malignancies. It has a clinical presentation similar to that of adenocarcinoma of the pancreas (ACP), but may have a worse overall prognosis, with most patients surviving for less than 2 years. METHODS: This was an institutional, retrospective, cohort analysis of 237 patients who underwent resection of pancreatic cancer with curative intent. RESULTS: Of the 237 cases examined, we identified 7 (2.9%) with histologically confirmed ASCAP. Demographics, comorbidities, risk factors, presenting symptoms, survival data, tumor characteristics, and types of treatment for each patient were included in the analysis. Risk factors for development of ASCAP were not conclusive. Although human papilloma virus (HPV) has been implicated in other squamous cell cancers, in our cohort, its involvement in ASCAP was 0%. Presurgical fine-needle aspiration failed to identify the invasive squamous cell component in all cases. In this cohort analysis, overall survival ranged from 3 to 25 months, with 2 patients surviving more than 20 months after surgical resection. With a median follow-up of 2.9 years, our data demonstrate a trend to worse median overall survival for ASCAP than for ACP (8.2 vs. 20.4 months; P = .23), with a limited number of long-term survivors. CONCLUSIONS: Although recommended, adjuvant treatment was inconsistently provided for patients in this ASCAP cohort. Published data show variability in overall survival, but our findings support that surgical resection is one of the few options for control of this rare, poorly understood pancreatic malignancy. Further research is necessary to define risk factors and adjuvant and neoadjuvant treatments, to help improve patient outcomes. PMID:23936547

    Cervical cancer is the third most common female cancer worldwide and the use of routine screening resulted in earlier stage and younger age at diagnosis. Fertility preservation via radical trachelectomy comes up as an option in such patients. Recent literature reviews confirm the safety of this operation with excellent oncologic outcomes in appropriately chosen patients. However, recurrent disease is likely and a strict follow-up is recommended to detect recurrences at an early stage following radical trachelectomy. In this report, a case who underwent radical trachelectomy and developed widespread recurrences 7 years after initial surgery possibly due to the lack of oncologic follow-up is discussed.

    Using a panel of 21 monoclonal and 2 polyclonal keratin antibodies, capable of detecting separately 11 subtypes of their epithelial intermediate filament proteins at the single cell level, we investigated keratin expression in 16 squamous cell carcinomas, 9 adenocarcinomas, and 3 adenosquamous carcinomas of the human uterine cervix. The keratin phenotype of the keratinizing squamous cell carcinoma was found to be most complex comprising keratins 4, 5, 6, 8, 13, 14, 16, 17, 18, 19, and usually keratin 10. The nonkeratinizing variety of the squamous cell carcinoma expressed keratins 6, 14, 17, and 19 in all cases, usually 4, 5, 7, 8, and 18, and sometimes keratins 10, 13, and 16. Adenocarcinomas displayed a less complex keratin expression pattern comprising keratins 7, 8, 17, 18, and 19, while keratin 14 was often present and keratins 4, 5, 10 and 13 were sporadically found in individual cells in a few cases. These keratin phenotypes may be useful in differential diagnostic considerations when distinguishing between keratinizing and nonkeratinizing carcinomas (using keratin 10, 13, and 16 antibodies), and also in the distinction between nonkeratinizing carcinomas and poorly differentiated adenocarcinomas, which do not express keratins 5 and 6. Keratin 17 may also be useful in distinguishing carcinomas of the cervix from those of the colon and also from mesotheliomas. Furthermore the presence of keratin 17 in a CIN I, II, or III lesion may indicate progressive potential while its absence could be indicative of a regressive behavior. Because most carcinomas express keratins 8, 14, 17, 18, and 19, we propose that this expression pattern reflects the origin of cervical cancer from a common progenitor cell, i.e., the endocervical reserve cell that has been shown to express keratins 5, 8, 14, 17, 18, and 19.

  13. Molecular crosstalk between apoptosis and autophagy induced by a novel 2-methoxyestradiol analogue in cervical adenocarcinoma cells

    PubMed Central

    2013-01-01

    Background 2-Methoxyestradiol has been shown to induce both autophagy and apoptosis in various carcinogenic cell lines. Although a promising anti-cancer agent, it has poor bioavailability and rapid in vivo metabolism which decreases its efficiency. In order to improve 2-methoxyestradiol’s anti-proliferative properties, a novel 2-methoxyestradiol analogue, 2-ethyl-3-O-sulphamoyl-estra-1,3,5 (10)16-tetraene (ESE-16), was previously in silico-designed in our laboratory. This study investigated ESE-16 for its anti-proliferative potential on a cervical adenocarcinoma cell (HeLa) cell line. Additionally, the possible intracellular crosstalk mechanisms between the two types of cell death were investigated. Methods and results HeLa cells exposed to 0.5 μM ESE-16 for 24 hours showed morphological evidence of both apoptotic and autophagic death pathways as assessed by polarization-optical transmitted light differential interference contrast microscopy, fluorescent microscopy and transmission electron microscopy. Flow cytometric cyclin B1 quantification revealed induction of programmed cell death after halting cell cycle progression in metaphase. Confocal microscopy demonstrated that ESE-16 caused microtubule fragmentation. Flow cytometric analysis of cell cycle progression and phosphatidylserine flip determination confirmed induction of apoptosis. Moreover, an increase in aggresome formation and microtubule-associated protein light chain, LC3, was demonstrated indicative of autophagy. Both caspase 8 and 3 were upregulated in a spectrophotometric analysis, indicating the involvement of the extrinsic pathway of apoptotic induction. Conclusions We conclude that the novel in silico-designed compound, ESE-16, exerts its anti-proliferative effect on the tumorigenic human epithelial cervical (HeLa) cells by sequentially targeting microtubule integrity, resulting in a metaphase block, causing induction of both autophagic and apoptotic cell death via a crosstalk mechanism that

    The importance of titanium dioxide (TiO2) and zinc oxide (ZnO), inorganic metal oxides nanoparticles (NPs) stems from their ubiquitous applications in personal care products, solar cells and food whitening agents. Hence, these NPs come in direct contact with the skin, digestive tracts and are absorbed into human tissues. Currently, TiO2 and ZnO are considered safe commercial ingredients by the material safety data sheets with no reported evidence of carcinogenicity or ecotoxicity, and do not classify either NP as a toxic substance. This study examined the direct effects of TiO2 and ZnO on HeLa cells, a human cervical adenocarcinonma cell line, and their membrane mechanics. The whole cell patch-clamp technique was used in addition to immunohistochemistry staining, TEM and atomic force microscopy (AFM). Additionally, we examined the effects of dexamethasone (DXM), a glucocorticoid steroid known to have an effect on cell membrane mechanics. Overall, TiO2 and ZnO seemed to have an adverse effect on cell membrane mechanics by effecting cell proliferation, altering cellular structure, decreasing cell-cell adhesion, activating existing ion channels, increasing membrane permeability, and possibly disrupting cell signaling.

  15. Proteomic biomarkers predicting lymph node involvement in serum of cervical cancer patients. Limitations of SELDI-TOF MS

    2012-01-01

    Background Lymph node status is not part of the staging system for cervical cancer, but provides important information for prognosis and treatment. We investigated whether lymph node status can be predicted with proteomic profiling. Material & methods Serum samples of 60 cervical cancer patients (FIGO I/II) were obtained before primary treatment. Samples were run through a HPLC depletion column, eliminating the 14 most abundant proteins ubiquitously present in serum. Unbound fractions were concentrated with spin filters. Fractions were spotted onto CM10 and IMAC30 surfaces and analyzed with surface-enhanced laser desorption time of flight (SELDI-TOF) mass spectrometry (MS). Unsupervised peak detection and peak clustering was performed using MASDA software. Leave-one-out (LOO) validation for weighted Least Squares Support Vector Machines (LSSVM) was used for prediction of lymph node involvement. Other outcomes were histological type, lymphvascular space involvement (LVSI) and recurrent disease. Results LSSVM models were able to determine LN status with a LOO area under the receiver operating characteristics curve (AUC) of 0.95, based on peaks with m/z values 2,698.9, 3,953.2, and 15,254.8. Furthermore, we were able to predict LVSI (AUC 0.81), to predict recurrence (AUC 0.92), and to differentiate between squamous carcinomas and adenocarcinomas (AUC 0.88), between squamous and adenosquamous carcinomas (AUC 0.85), and between adenocarcinomas and adenosquamous carcinomas (AUC 0.94). Conclusions Potential markers related with lymph node involvement were detected, and protein/peptide profiling support differentiation between various subtypes of cervical cancer. However, identification of the potential biomarkers was hampered by the technical limitations of SELDI-TOF MS. PMID:22694804

    Cervical neuroendocrine carcinomas are rare, aggressive tumors and their immunohistochemical features and clonal relationship to coexisting tumors are incompletely described. Twenty-eight cases were identified (17 small cell, 9 large cell, and 2 mixed), 10 of which had an invasive squamous or adenocarcinoma component. Staining for synaptophysin, chromogranin A, TTF1, c-kit, CD44, and p16 was performed. Analyses for loss of heterozygosity (LOH) at 5 polymorphic microsatellite markers (D3S1300, D9S171, D11S914, D13S319, and TP53) and X-chromosome inactivation were performed. Of 17 cases with available blocks, 13 (76%) were synaptophysin+, 8 (47%) were chromogranin A+, 8 (47%) were TTF1+, 7 (41%) were c-kit+, and 6 (35%) were CD44+. Strong patchy or strong diffuse p16 staining was seen in all cases. LOH and X-chromosome inactivation analysis were performed for 17 cases, 8 of which had a coexisting squamous or adenocarcinoma component. Five of the 8 (63%) cases with 2 components showed allelic loss in both components. All 5 of these cases demonstrated identical LOH between the neuroendocrine and squamous or adenocarcinoma components. Nonrandom X-chromosome inactivation was seen in the neuroendocrine and other components in 4 of the 8 cases. In all 4 cases the pattern of inactivation was identical between the 2 components. Cervical neuroendocrine carcinomas have features similar to other extrapulmonary neuroendocrine carcinomas, including expression of TTF1, c-kit, and CD44. Consistent staining for p16 is also seen. Concordant genetic alterations support common clonal origin for neuroendocrine carcinomas with a coexisting squamous or adenocarcinoma component. PMID:26630233

    Detection of E6/E7 mRNA expression using the real-time nucleic acid sequence-based amplification assay (NASBA) PreTect HPV-Proofer was compared with results of human papillomavirus (HPV) DNA detection in 98 paraffin-embedded samples from patients with cervical adenocarcinoma. HR-HPV DNA was detected in 61 (62%), while HR-HPV E6/E7 mRNA was detected in 63 (64%) of the samples. Correlation between results from DNA analyses and the E6/E7 mRNA assay showed consistent results in 87% of samples (47 of 54). The results from these two methods in detecting presence of HPV infection of any type agreed in 77%. Overall agreement between the methods was seen in 82 of the 98 cases (84%). When evaluating change in sensitivity for detection of HPV positives by adding more HPV types to the HPV DNA assay, maximum sensitivity was reached by targeting four HPV types. The coverage of HPV DNA presence was 76.9%, while the E6/E7 mRNA assay achieved a maximum coverage of 80.8% using only three HPV types. Thus, E6/E7 oncogene expression analysis may provide a more objective test for assessment of neoplastic glandular cells. Further studies may reveal whether the clinical performance of the E6/E7 mRNA assay will be of prognostic value in management of cervical adenocarcinoma. PMID:20428778

    Purpose: To investigate, in a phase III randomized trial, whether postoperative external-beam irradiation to the standard pelvic field improves the recurrence-free interval and overall survival (OS) in women with Stage IB cervical cancers with negative lymph nodes and certain poor prognostic features treated by radical hysterectomy and pelvic lymphadenectomy. Methods and Materials: Eligible patients had Stage IB cervical cancer with negative lymph nodes but with 2 or more of the following features: more than one third (deep) stromal invasion, capillary lymphatic space involvement, and tumor diameter of 4 cm or more. The study group included 277 patients: 137 randomized to pelvic irradiation (RT) and 140 randomized to observation (OBS). The planned pelvic dose was from 46 Gy in 23 fractions to 50.4 Gy in 28 fractions. Results: Of the 67 recurrences, 24 were in the RT arm and 43 were in the OBS arm. The RT arm showed a statistically significant (46%) reduction in risk of recurrence (hazard ratio [HR] = 0.54, 90% confidence interval [CI] = 0.35 to 0.81, p = 0.007) and a statistically significant reduction in risk of progression or death (HR = 0.58, 90% CI = 0.40 to 0.85, p = 0.009). With RT, 8.8% of patients (3 of 34) with adenosquamous or adenocarcinoma tumors recurred vs. 44.0% (11 of 25) in OBS. Fewer recurrences were seen with RT in patients with adenocarcinoma or adenosquamous histologies relative to others (HR for RT by histology interaction = 0.23, 90% CI = 0.07 to 0.74, p = 0.019). After an extensive follow-up period, 67 deaths have occurred: 27 RT patients and 40 OBS patients. The improvement in overall survival (HR = 0.70, 90% CI = 0.45 to 1.05, p = 0.074) with RT did not reach statistical significance. Conclusions: Pelvic radiotherapy after radical surgery significantly reduces the risk of recurrence and prolongs progression-free survival in women with Stage IB cervical cancer. RT appears to be particularly beneficial for patients with adenocarcinoma or

    Adenosquamous carcinoma of the pancreas (ASCP) is a rare entity. Like adenocarcinoma of the pancreas, overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP. Molecular characterization revealed overexpression in MRP1 (80%), MGMT (79%), TOP2A (75), RRM1 (42%), TOPO1 (42%), PTEN (45%), CMET (40%), and C-KIT (10%) among others. One hundred percent of samples tested were positive for KRAS mutations. This analysis shows heretofore unsuspected leads to be considered for treatments of this rare type of exocrine pancreas cancer. Molecular profiling may be appropriate to provide maximum information regarding the patient’s tumor. Further work should be pursued to better characterize this disease. PMID:26380056

    The efficacy of radiotherapy (RT) for adenocarcinoma (AC) is controversial, although patients with AC of the uterine cervix are treated in a similar manner to those with squamous cell carcinoma (SCC). This retrospective study was conducted to evaluate the efficacy of adjuvant RT for patients with AC compared to those with SCC following radical hysterectomy. A total of 820 patients with stage IB-IIB cervical cancer, who underwent type III radical hysterectomy between 1997 and 2003, were retrospectively examined; the sample included 280 patients with AC and 540 with SCC. A total of 139 patients with AC and 327 with SCC underwent adjuvant treatment. The histological type did not affect the outcome for patients with stage I disease; however, stage II patients with AC exhibited a significantly worse 5-year overall survival (OS) rate compared to those with SCC. Patients with SCC exhibited significantly higher lymph node involvement compared to those with AC in stage IB1; however, there were no differences between stages IB2 and II. Among patients with lymph node involvement, patients with AC exhibited a significantly worse 5-year survival rate compared to those with SCC (46.4 vs. 72.3%, respectively; P=0.0005). Among patients receiving adjuvant RT, those with AC recurred more frequently compared to those with SCC, particularly in the pelvic cavity, including the vaginal stump and/or pelvis (24.6 vs. 10.5%, respectively; P= 0.0022). By contrast, the histological type did not affect the incidence of recurrence in paraaortic lymph nodes and/or distant recurrence. In conclusion, RT may not suffice as an adjuvant treatment for patients with cervical AC following radical hysterectomy. PMID:24649246

    Cervical glandular neoplasias (CGN) present a challenge for cervical cancer prevention due to their complex histopathology and difficulties in detecting preinvasive stages with current screening practices. Reports of human papillomavirus (HPV) prevalence and type-distribution in CGN vary, providing uncertain evidence to support prophylactic vaccination and HPV screening. This study [108288/108290] assessed HPV prevalence and type-distribution in women diagnosed with cervical adenocarcinoma in situ (AIS, N = 49), adenosquamous carcinoma (ASC, N = 104), and various adenocarcinoma subtypes (ADC, N = 461) from 17 European countries, using centralised pathology review and sensitive HPV testing. The highest HPV-positivity rates were observed in AIS (93.9%), ASC (85.6%), and usual-type ADC (90.4%), with much lower rates in rarer ADC subtypes (clear-cell: 27.6%; serous: 30.4%; endometrioid: 12.9%; gastric-type: 0%). The most common HPV types were restricted to HPV16/18/45, accounting for 98.3% of all HPV-positive ADC. There were variations in HPV prevalence and ADC type-distribution by country. Age at diagnosis differed by ADC subtype, with usual-type diagnosed in younger women (median: 43 years) compared to rarer subtypes (medians between 57 and 66 years). Moreover, HPV-positive ADC cases were younger than HPV-negative ADC. The six years difference in median age for women with AIS compared to those with usual-type ADC suggests that cytological screening for AIS may be suboptimal. Since the great majority of CGN are HPV16/18/45-positive, the incorporation of prophylactic vaccination and HPV testing in cervical cancer screening are important prevention strategies. Our results suggest that special attention should be given to certain rarer ADC subtypes as most appear to be unrelated to HPV. PMID:26096203

    A case of adenocarcinoma in the pharyngo oesophageal junction extending to the upper cervical oesophagus is described. In this case the neo-plastic changes had occurred from columnar epithelium of gastric and intestinal type: Barrett's oesophagus. The Barrett's mucosa involved the whole length of the oesophagus. Because of the general condition of the patient and advanced stage of the tumour surgical treatment was considered inappropriate. Endoscopic Photofrin Photodynamic Therapy was used with good palliation of dysphagia. The patient survived for 9 months, dying form carcinomatosis and oesophago-airway fistula. As far as can be documented only one such case has been previously reported in the literature. PMID:19356659

    We investigated the frequency of major driver oncogenes in lung adenosquamous cell carcinoma (ASC) cases. Frequency of EGFR, K-Ras, B-Raf, PIK3CA, DDR2, ALK, and PDGFRA gene mutations was examined in 56 patients using next-generation sequencing, polymerase chain reaction, and Sanger sequencing. Macrodissection or microdissection was performed in 37 cases to separate the adenomatous and squamous components of ASC. The overall mutation rate was 64.29%, including 55.36%, 7.14%, and 1.79% for EGFR, K-Ras, and B-Raf mutations, respectively. PIK3CA mutation was detected in three cases; all involved coexisting EGFR mutations. Of the 37 cases, 34 were convergent in two components, while three showed EGFR mutations in the glandular components and three showed PIK3CA mutations in the squamous components. With respect to EGFR mutations, the number of young female patients, nonsmokers, and those with positive pleural invasion was higher in the mutation-positive group than that in the mutation-negative. K-Ras mutation was significantly associated with smoking. Overall survival in the different EGFR mutation groups differed significantly. The frequency and clinicopathological characteristics of EGFR- and K-Ras-mutated adenosquamous lung carcinoma were similar to that noted in Asian adenocarcinomas patients. The high convergence mutation rate in both adenomatous and squamous components suggests monoclonality in ASC. PMID:26923333

    Introduction Squamous cell carcinoma (SCC), adenocarcinoma (AC), and adenosquamous carcinoma (ASC) are the most common histological subtypes of cervical cancer. Differences in the somatic mutation profiles of these subtypes have been suggested. We investigated the prevalence of somatic hot-spot mutations in three well-defined cohorts of SCC, AC, and ASC and determined the additional value of mutation profiling in predicting disease outcome relative to well-established prognostic parameters. Materials and Methods Clinicopathological data were collected for 301 cervical tumors classified as SCC (n=166), AC (n=55), or ASC (n=80). Mass spectrometry was used to analyze 171 somatic hot-spot mutations in 13 relevant genes. Results In 103 (34%) tumors, 123 mutations were detected (36% in SCC, 38% in AC, and 28% in ASC), mostly in PIK3CA (20%) and KRAS (7%). PIK3CA mutations occurred more frequently in SCC than AC (25% vs. 11%, P=0.025), whereas KRAS mutations occurred more frequently in AC than SCC (24% vs. 3%, P<0.001) and ASC (24% vs. 3%, P<0.001). A positive mutation status correlated with worse disease-free survival (HR 1.57, P=0.043). In multivariate analysis, tumor diameter, parametrial infiltration, and lymph node metastasis, but not the presence of a somatic mutation, were independent predictors of survival. Conclusion Potentially targetable somatic mutations occurred in 34% of cervical tumors with different distributions among histological subtypes. Precise classification of cervical carcinomas in combination with mutation profiling is valuable for predicting disease outcome and may guide the development and selection of tumor-specific treatment approaches.

    Adenosquamous carcinoma (ASC) is an uncommon variant of pancreatic neoplasm. We sought to trace the mode of tumor progression using specimens of ASC associated with intraductal papillary mucinous neoplasm (IPMN) of the pancreas. A resected specimen of the primary pancreatic ASC, developed in a 72-year-old man, was subjected to mutation profiling using amplicon-targeted sequencing and digital polymerase chain reaction. DNA was isolated from each histological compartment including noninvasive IPMN, squamous cell carcinoma (SCC), and adenocarcinoma (AC). Histologically, an IPMN with a large mural nodule was identified. The invasive tumor predominantly consisted of SCC, and a smaller AC was found around the lesion. Squamous metaplasias were sporadically distributed within benign IPMNs. Mutation alleles KRAS and GNAS were identified in all specimens of IPMN including the areas of squamous metaplasia. In addition, these mutations were found in SCC and AC. Clear transition from flat/low-papillary IPMN to SCC indicated a potent invasion front, and the SCC compartment was genetically unique, because the area has a higher frequency of mutation KRAS. The invasive tumors with distinct histological appearances shared the form of noninvasive IPMN as a common precursor, rather than de novo cancer, suggesting the significance of a genetic profiling scheme of tumors associated with IPMN.

    Disparities in Cervical Cancer (CC) mortality outcomes between African American (AA) and White women have been studied for decades. However, conclusions about the effect of race on CC survival differ across studies. This study assessed differences in CC survival between AA and White women diagnosed between 1985 and 2010 and treated at two major hospitals in the southeastern US. The study sample included 925 AA and 1192 White women diagnosed with cervical adenocarcinoma, adenosquamous cell carcinoma, or squamous cell carcinoma. Propensity score adjustment and matching were employed to compare 5-year survival between the two racial groups. Crude comparisons suggested relevant racial differences in survival. However, the racial differences became of small magnitude after propensity-score adjustment and in matched analyses. Nonlinear models identified age at diagnosis, cancer stage, mode of treatment, and histological subtype as the most salient characteristics predicting 5-year survival of CC, yet these characteristics were also associated with race. Crude racial differences in survival might be partly explained by underlying differences in the characteristics of racial groups, such as age at diagnosis, histological subtype, cancer stage, and the mode of treatment. The study results highlight the need to improve access to early screening and treatment opportunities for AA women to improve posttreatment survival from CC. PMID:27185053

    Background Non Small Cell Lung Cancer is a highly heterogeneous tumor. Histologic intratumor heterogeneity could be ‘major’, characterized by a single tumor showing two different histologic types, and ‘minor’, due to at least 2 different growth patterns in the same tumor. Therefore, a morphological heterogeneity could reflect an intratumor molecular heterogeneity. To date, few data are reported in literature about molecular features of the mixed adenocarcinoma. The aim of our study was to assess EGFR-mutations and ALK-rearrangements in different intratumor subtypes and/or growth patterns in a series of mixed adenocarcinomas and adenosquamous carcinomas. Methods 590 Non Small Cell Lung Carcinomas tumor samples were revised in order to select mixed adenocarcinomas with available tumor components. Finally, only 105 mixed adenocarcinomas and 17 adenosquamous carcinomas were included in the study for further analyses. Two TMAs were built selecting the different intratumor histotypes. ALK-rearrangements were detected through FISH and IHC, and EGFR-mutations were detected through IHC and confirmed by RT-PCR. Results 10/122 cases were ALK-rearranged and 7 from those 10 showing an intratumor heterogeneity of the rearrangements. 12/122 cases were EGFR-mutated, uniformly expressing the EGFR-mutated protein in all histologic components. Conclusion Our data suggests that EGFR-mutations is generally homogeneously expressed. On the contrary, ALK-rearrangement showed an intratumor heterogeneity in both mixed adenocarcinomas and adenosquamous carcinomas. The intratumor heterogeneity of ALK-rearrangements could lead to a possible impact on the therapeutic responses and the disease outcomes. PMID:26422230

    Objective To analyze the incidence of diagnostic discrepancy between frozen-section and final diagnosis of the endocervical margin at time of radical trachelectomy and to apply an objective scoring system to non-invasive endocervical glandular atypia to determine its utility in distinguishing benign from malignant lesions. Methods Histologic slides from 19 cases of radical trachelectomy performed for invasive endocervical adenocarcinoma were evaluated for correlation between the frozen and permanent sections of the endocervical margin. An objective scoring system for grading non-invasive endocervical glandular lesions proposed by Ioffe et al. was also applied to the frozen and permanent section slides and compared to the final diagnosis. Results There was 84% concordance between the frozen-section and final diagnosis using histology alone, vs. 95% concordance using the Ioffe scoring system. One trachelectomy was converted to completion hysterectomy for what was presumed to be adenocarcinoma in situ at the margin, which in retrospect, was a benign lesion and was correctly classified using the Ioffe system. Most of the discrepancies were due to misinterpretation of tubal metaplasia, tubo-endometrioid metaplasia, and atypical tubal metaplasia as adenocarcinoma in situ. Conclusion Benign mimics of endocervical adenocarcinoma in situ can be difficult to distinguish from malignant lesions, especially during frozen-section evaluation of the trachelectomy. Correctly diagnosing the margin status intraoperatively has great clinical impact and the application of an objective scoring system, like that proposed by Ioffe et al., can increase diagnostic accuracy when applied to frozen-section slides and better correlates with final diagnosis when compared to histology alone.

    Introduction Splenic metastasis of gallbladder carcinoma is extremely rare. Specific anatomical, histological, and functional properties of spleen are believed to be responsible for the rarity of solitary splenic metastasis. Presentation of case We present the case of a 62-year-old female who developed metachronous splenic metastasis of adenosquamous carcinoma of the gallbladder. We performed central bisegmentectomy of the liver for gallbladder carcinoma. The patient subsequently presented 3 months later with isolated splenic metastasis and liver metastasis. Splenectomy and partial hepatectomy was performed at this time. Histological examination confirmed metastatic adenosquamous carcinoma of the gallbladder. No signs of recurrence were observed at 3 months after the second surgery. Discussion Although splenectomy provides a potential means of radical treatment in patients with isolated splenic metastases, it should be performed with caution as splenic metastatic lesions may represent the initial clinical manifestation of systemic metastases at multiple sites. In this case, radical surgery was performed following the confirmation of no new unresectable metastatic lesions or systemic dissemination. Conclusion This is the first report on the adenosquamous splenic metastasis from the gallbladder carcinoma. Curative resection may be the treatment of choice for prolonging survival in patients with the splenic metastasis of gallbladder carcinoma. PMID:26852359

    The current study describes a case of adenosquamous carcinoma originating from a thyroglossal duct cyst (TGDC). A 77-year-old man presented with an asymptomatic mass in the left mid-neck, which was soft and mobile on palpation. Fine-needle aspiration was performed, but cytology did not detect any malignant cells. Computed tomography demonstrated a single cystic lesion in the left lobe of the thyroid gland; therefore, surgery was performed on the suspected thyroid cyst. However, it was identified intraoperatively that the lesion was separated from the thyroid gland and instead adhered to an additional hyoid bone; therefore, the Sistrunk procedure was performed. Histopathological examination of the resected tumor confirmed the diagnosis of adenosquamous carcinoma originating from a TGDC. Carcinoma arising from a TGDC is rare, and accounts for 1% of all TGDC cases. The most common subtype of carcinoma associated with TGDC is papillary carcinoma, whilst adenosquamous carcinoma developing from a TGDC is extremely rare, with only one case currently reported in the literature. Although a consensus for the management of this disease has not yet been established, adequate surgical excision with long-term follow-up is currently the preferred treatment. PMID:27073536

    In 2013, a 76-year-old male with a cardiac pacemaker was diagnosed with adenosquamous carcinoma of the duodenum. Subsequently, a pancreatoduodenectomy and lymph node dissection were performed, and 12 cycles of adjuvant chemotherapy (modified FOLFOX6 regimen), which consisted of fluorouracil, leucovorin and oxaliplatin, were administered via a central venous catheter. At 5 months after the completion of adjuvant chemotherapy, the patient experienced the sudden onset of severe pain at the back right of the ear, edema of the right side of the face and right jugular vein dilatation. Computed tomography (CT) revealed filling defects in the superior vena cava (SVC) and right brachiocephalic vein, indicating catheter-induced venous thrombosis. Although the catheter was removed and anti-coagulation therapy, aspiration of the thrombosis and ballooning dilatation were performed immediately, the patient's symptoms were not ameliorated. Notably, histological examination following thrombus aspiration revealed metastatic cancer cells, and fluorodeoxyglucose-positron emission tomography/CT identified metabolically active nodules in the SVC at locations consistent with the initial duodenal tumors detected by CT and in the first thoracic vertebrae. The tumor thrombus rapidly increased in size and resulted in worsening dyspnea. Subsequently, radiotherapy was performed, followed by chemotherapy, which relieved the systemic symptoms and suppressed the tumor growth. Adenosquamous carcinoma of the duodenum is extremely rare, and to the best of our knowledge, intraluminal SVC metastasis as a result of adenosquamous carcinoma of the duodenum has not been reported previously. The placement of a cardiac pacemaker, central venous catheter and tumor cells possessing high metastatic potential are hypothesized to have contributed to this rare case of metastasis. PMID:26870254

    Purpose:We evaluated the effects of intra-arterial infusion therapy by comparing the results obtained with a combination of intra-arterial anticancer drugs with and without transcatheter arterial embolization (TAE) in patients with cervical cancer.Methods:Between April 1999 and March 2003, intra-arterial therapy was administered to 45 patients (mean age 49 years) with cervical cancer. Of these, 18 had stage IIb , 4 had stage IIIa, 19 had stage IIIb, and 4 had stage IVb cancer; the histopathologic types were squamous cell carcinoma (n = 35), adenocarcinoma (n = 8), and adenosquamous carcinoma (n = 2). A total of 45 patients gave their informed consent and were randomized on a continuous basis into one of three groups according to the therapeutic protocols: group A consisted of 15 patients who received cisplatin, group B consisted of 17 patients who received cisplatin, mitomycin, doxorubicin hydrochloride, and 5-fluorouracil, and group C consisted of 13 patients who received cisplatin and TAE. Each protocol was administered twice with a 3 week interval between treatments. The efficacy of treatment was evaluated on the basis of the tumor reduction ratio (%) using MR imaging and the side effects were analyzed.Results:In groups A, B, and C, the tumor reduction ratio was 54%, 84%, and 86%, respectively; it was significantly greater in groups B and C than in group A (p < 0.01). The difference between groups B and C was not statistically significant. Although all group C patients developed severe pain after TAE, the pain was controlled with analgesics. Thrombocytopenia occurred in 6 of 17 (35%) group B patients.Conclusion:Group B and C patients had better tumor reduction than those in group A. Fewer hematologic complications occurred in group C patients compared with group B.

    We investigated the first site of distant failure after carbon ion radiotherapy (C-ion RT) for locally advanced cervical cancer in three clinical trials. A total of 91 cases were enrolled in the three trials (Protocol 9702, 9704 and 9902). Histologically, 36 cases had squamous cell carcinoma (SqCC) and 55 cases had adenocarcinoma (AC), including 13 with adenosquamous cell carcinoma. The number of cases with Stage IIB, IIIB and IVA disease was 21, 59 and 11, respectively. Of the 91 cases, 42 had positive pelvic lymph nodes (PLNs). The median tumor size was 6.0 cm (range, 3.0–12.0 cm). The median follow-up duration for all cases was 40 months (range, 7–181 months). A total of 40 cases developed distant failure as the first site of failure: 13 of 36 (36.1%) SqCC cases had distant failure, with 9 of them with para-aortic lymph node (PALN) failure; 27 of 55 (44.0%) AC cases had distant failure, and 23 of them had distant failure excluding PALN metastasis. Distant failure rates of SqCC cases who had positive and negative PLNs before C-ion RT were 61.1% and 11.1%, respectively (P = 0.0045). Those of AC cases were 54.2% and 45.2%, respectively (P = 0.507). In conclusion, there were high rates of distant failure after C-ion RT in AC cases regardless of PLN status, and there were high rates of distant failure after C-ion RT, especially PALN failure, in SqCC cases with positive PLNs.

    Gastric adenosquamous carcinoma (ASC) is a rare type of gastric cancer. It is a mixed neoplasm, consisting of glandular cells and squamous cells. It is often diagnosed at an advanced stage, thus carrying a poor prognosis. We describe a case of a 73-year-old male, who presented with refractory fever and an intra-abdominal mass on imaging. He underwent a laparoscopic exploration followed by a successful totally laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer. Postoperative pathology revealed primary gastric ASC (T4aN0M0). The patient received adjuvant radiotherapy and chemotherapy with S1 and is alive 20 mo after surgery without recurrence. This is the first case of advanced gastric ASC with fever as the initial presentation treated with totally laparoscopic total gastrectomy reported in the English literature. PMID:25110448

    Adenosquamous carcinoma of the breast (ASBC) is a rare variant of metaplastic breast cancer with both glandular as well as squamous differentiation. Their lack of distinct imaging characteristics, sometimes subtle histological characteristics and overlapping features with other benign lesions pose a diagnostic challenge. Unlike other forms of metaplastic breast cancer, low-grade adenosquamous carcinoma (LGAC) tends to follow an indolent course with favourable prognosis. We reviewed eight cases of LGAC in our institution from June 2005 to March 2014. In six cases, LGAC was only found after excisional biopsy. In our patients, LGAC frequently co-existed with other forms of breast pathology. Two patients had incidental findings of LGAC alongside their primary malignant tumour (adenoid cystic carcinoma and invasive ductal carcinoma in one, four foci between 0.5 and 4.0 mm within a radial sclerosing lesion adjacent to a malignant phyllodes tumour in the other). A further four patients had LGAC within a complex sclerosing lesion. One patient had a focus of LGAC within a fibroadenoma. One had a focus of LGAC within a benign phyllodes tumour. None of the patients had evidence of nodal involvement. A high degree of suspicion is recommended as such lesions tend to be incidental histological findings within benign tumours or within complex sclerosing lesions. Although the risk of nodal and distant metastasis is low, the potential for local recurrence necessitates aggressive local excision with margin clearance. The role of axillary dissection has yet to be defined and routine sentinel node biopsy and axillary clearance may not be necessary in view of rarity of nodal metastasis in literature. Benefit from adjuvant radiotherapy or chemotherapy is not clearly defined. All eight patients in our study have shown no evidence of recurrence after definitive surgery but longer periods of surveillance is required. PMID:25986061

    Adenosquamous carcinoma is a rare colorectal tumor with few cases described in the literature; no children have been reported. A 12-year-old-girl presented tenesmus, diarrhea, and iron deficiency anemia. Intestinal bowel disease was suspected, colonoscopy and biopsy were performed and the diagnosis was a squamous cell carcinoma. Chemoradiation therapy based on last colorectal cancer guidelines was started. Complete regression of the primary tumor was observed with lymph node progression. The pathology report of the lymphadenectomy revealed metastasis of adenosquamous carcinoma, although there was not any adenomatous component in the first biopsy. The patient presented progression with liver metastases, despite stable local disease due to response to first-line treatment of the squamous component. PMID:26181422

    A 76-year-old woman was referred to our hospital with anorexia. Computed tomography revealed a tumor lesion measuring 110mm in the liver at S4/5 with calcification and swelling of a paraaortic lymph node. The gallbladder was not visualized. Histological examination of a biopsy specimen from the liver tumor revealed squamous cell and undifferentiated carcinomas, and several tumor markers were elevated. Therefore, we diagnosed the patient with gallbladder adenosquamous cell carcinoma T3N2M0 stage III. Because the serum parathyroid hormone-related protein (PTHrP) and granulocyte-colony stimulating factor (G-CSF) levels were significantly elevated, we suspected that PTHrP and G-CSF production occurred because of adenosquamous cell carcinoma in the gallbladder. We initiated chemotherapy with S-1. PMID:27593366

    Over the past three decades, the incidence of lung adenocarcinoma has increased worldwide. Most individuals with lung adenocarcinoma (especially women) are nonsmokers. Reported risk factors for the development of lung adenocarcinoma include cigarette smoking; exposure to cooking fumes, air pollution, second-hand smoke, asbestos, and radon; nutritional status; genetic susceptibility; immunologic dysfunction; tuberculosis infection; and asthma. Human papillomavirus (HPV) infection is a known risk factor for the development of squamous cell carcinoma (SCC), but it has not been thoroughly assessed as a potential risk factor for the development of pulmonary adenocarcinoma. More than 50% of people are infected with HPV during their lifetimes, either via intrauterine or postnatal infection. Recent studies involving Taiwanese patients have demonstrated a possible association between HPV infection and the risk of developing pulmonary adenocarcinoma. HPV transmission pathways have not yet been conclusively identified. The observation of certain types of HPV in association with cervical and oral SCC raises the possibility of sexual transmission of HPV from the cervix to the oral cavity, with subsequent transmission to the larynx and then to the lung. HPV infection and metaplasia in lung tissue may increase an individual's susceptibility to the tumorigenesis of pulmonary adenocarcinoma. Further epidemiologic and pathologic investigations will be necessary to establish a causal relation. PMID:15368331

    This study describes a unique subset of ciliated, human papillomavirus (HPV) related, adenosquamous carcinomas (AsqCA) of the head and neck that in contrast to most AsqCA, often show areas with lower grade cytonuclear features. They are comprised of largely non-keratinizing squamous cell carcinoma components with cystic change, gland formation, mucin production, and cilia in tumor cells. Seven cases of ciliated AsqCA were retrieved. Site distribution was as follows: palatine tonsil-3/7, base of tongue-1/7, and neck (unknown primary site)-3/7. Despite the occasional resemblance to mucoepidermoid carcinoma (MEC), the tumors showed focal keratinizing morphology and atypia, and all tumors were negative for MAML2 rearrangements. Oropharyngeal and neck tumors were uniformly p16 positive and showed punctate staining by in situ hybridization for high risk HPV DNA. There were two distant metastases (lung), and one tumor related death. Thus, ciliated AsqCA are HPV-associated lesions that pose unique pitfalls, closely mimicking MEC and other salivary gland tumors. These tumors add to the list of those which defy the dogma that ciliated epithelium always equates to a benign process. PMID:26411881

    Background Pancreatic adenosquamous carcinoma (PASC) accounts for only 1-4% of all exocrine pancreatic cancers and carries a particularly poor prognosis. This retrospective study was performed to determine whether inclusion of a platinum agent as part of adjuvant therapy is associated with improved survival in patients with resected PASC. Methods Records of all patients who underwent pancreatic resection at Johns Hopkins Hospital from 1986 to 2012 were reviewed to identify those with PASC. Multivariable Cox proportional hazards modeling was used to assess for significant associations between patient characteristics and survival. Results In total, 62 patients (1.1%) with resected PASC were identified among 5,627 cases. Median age was 68 [interquartile range (IQR), 57-77] and 44% were female. Multivariate analysis revealed that, among all patients (n=62), the following factors were independently predictive of poor survival: lack of adjuvant therapy [hazard ratio (HR) =3.6; 95% confidence interval (CI), 1.8-7.0; P<0.001], margin-positive resection (HR =3.5; 95% CI, 1.8-6.8; P<0.001), lymph node involvement (HR =3.5; 95% CI, 1.5-8.2; P=0.004), and age (HR =1.0; 95% CI, 1.0-1.1; P=0.035). There were no significant differences between patients who did and did not receive adjuvant therapy following resection (all P>0.05). A second multivariable model included only those patients who received adjuvant therapy (n=39). Lack of inclusion of a platinum agent in the adjuvant regimen (HR =2.4; 95% CI, 1.0-5.8; P=0.040) and larger tumor diameter (HR =1.3; 95% CI, 1.0-1.6; P=0.047) were independent predictors of inferior survival. Conclusions Addition of a platinum agent to adjuvant regimens for resected PASC may improve survival among these high-risk patients, though collaborative prospective investigation is needed.

    BACKGROUND In cervical adenocarcinoma, surgical treatment involves bilateral oophorectomy, which affects the long-term quality of life. The aim of our study was to access the incidence of ovarian metastasis in early-stage cervical adenocarcinoma and to suggest an algorithm for the triage of these patients to preserve the ovaries. MATERIAL AND METHODS A total 101 patients with cervical adenocarcinoma who had undergone radical hysterectomy with pelvic lymphadenectomy and bilateral oophorectomy were included in this study. Data on the clinicopathologic characteristics of the cases were collected and low risk factors for ovarian metastasis in early-stage cervical adenocarcinoma were analyzed. RESULTS The ovary metastasis rate of cervical adenocarcinoma in this study was 4.95%, while it is only 2% in stage IB1. Pathological grade, LSVI, lymph node status, tumor size, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis, while LSVI, lymph node status, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis in stage IB. Multivariate analysis revealed that LVSI and lymph node metastasis were independent risk factors for ovarian metastasis in all stages of cervical adenocarcinoma, but involvement of the junction of the cervix and the body of the uterus was an independent risk factor for ovarian metastasis in stage IB. CONCLUSIONS The incidence of ovarian metastasis in cervical adenocarcinoma is low. Our study suggests that ovarian preservation is safe and feasible in patients with no risk factors for ovarian metastasis. Further prospective studies are warranted. PMID:26852916

    2016-02-01

    Stratified mucin-producing intraepithelial lesion (SMILE) is a cervical intraepithelial lesion, distinct from conventional squamous or glandular counterparts, believed to arise from embryonic cells at the transformation zone by transdifferentiation during high-risk HPV-associated carcinogenesis. It is characterized by stratified, immature epithelial cells displaying varying quantities of intracytoplasmic mucin throughout the majority of the lesional epithelium. We identified a distinct form of invasive cervical carcinoma with morphologic features identical to those in SMILE, which we have termed "invasive stratified mucin-producing carcinoma." Fifteen cases from 15 patients (mean 36 y; range, 22 to 64 y) were retrieved from the pathology archives of multiple institutions with a diagnosis of either SMILE or invasive cervical carcinoma with a description or comment about the invasive tumor's resemblance to SMILE. Seven cases had solely intraepithelial disease with a component of SMILE (mean 29 y; range, 22 to 40 y). The 8 other cases had invasive stratified mucin-producing carcinoma (mean 44; range, 34 to 64 y) in which SMILE was identified in 7. All cases of invasive stratified mucin-producing carcinoma demonstrated stratified, immature nuclei with intracytoplasmic mucin, which morphologically varied between cases from "mucin-rich" to "mucin-poor" in a similar manner to SMILE. All cases had mitotic figures and apoptotic debris, and an intralesional neutrophilic infiltrate was seen in the majority of cases. In cases of invasive carcinoma, the depth of invasion ranged from <1 to 19 mm. Follow-up information was available in 8 cases and ranged from 1 to 36 months (mean 11 mo). Three cases of invasive stratified mucin-producing carcinoma had biopsy or resection-proven metastatic carcinoma on follow-up. These 15 cases of cervical stratified mucin-producing lesions show a combination of intraepithelial and invasive growth patterns. Given that SMILE is well rooted as a

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

  18. Application of a Pattern-based Classification System for Invasive Endocervical Adenocarcinoma in Cervical Biopsy, Cone and Loop Electrosurgical Excision (LEEP) Material: Pattern on Cone and LEEP is Predictive of Pattern in the Overall Tumor.

    2016-09-01

    A pattern-based classification system has been recently proposed for invasive endocervical adenocarcinoma, which is predictive of the risk of nodal metastases. Identifying cases at risk of nodal involvement is most relevant at the time of biopsy and loop electrosurgical excision procedure (LEEP) to allow for optimal surgical planning, and, most importantly, consideration of lymphadenectomy. This study aims to determine the topography of patterns of stromal invasion in invasive endocervical adenocarcinoma with emphasis on patterns in biopsy, cone, and LEEP. Invasive pattern was assessed following the pattern-based classification (Patterns A, B, and C) in 47 invasive endocervical adenocarcinomas treated with hysterectomy or trachelectomy and correlated with pattern of invasion at the tumor surface (2 mm of tumor depth) and on preoperative biopsy and cone/LEEP. Patterns A, B, and C were present in 21.3%, 36.2%, and 42.5% of cases, respectively. Most pattern A cases were Stage IA (90%), whereas most Pattern B and C cases were Stage IB (76.5% and 80%, respectively). Horizontal spread was on average larger in Pattern C (24.1 mm) than in Patterns A and B (7.7 and 12.3 mm, respectively). Pattern at the tumor surface correlated with the overall pattern in 95.7% of cases. Concordance between patterns at cone/LEEP and hysterectomy was 92.8%; the only discrepant case was upgraded from Pattern A on LEEP to C on final excision. Agreement between patterns in biopsy and the overall tumor, however, was only 37.5%. In all discrepant cases, biopsy failed to reveal destructive invasion, which was evident on excision. All discrepant biopsies with pattern A showed glandular complexity resembling exophytic papillary growth but did not meet criteria for destructive invasion. On excision, marked gland confluence with papillary architecture was evident. We conclude that the pattern of invasion on cone/LEEP is a good predictor of pattern of invasion on hysterectomy, particularly if there is

    Gastric adenosquamous carcinoma is a rare malignancy with a poor prognosis. We recently performed palliative gastrectomy for a gastric adenosquamous carcinoma with peritoneal dissemination and provided a course of systemic chemotherapy with S-1 plus paclitaxel(PTX)after the surgery. No serious adverse events were observed, and treatment with S-1 plus PTX was continued for 1 year before being switched to adjuvant chemotherapy with S-1 alone for another year. The tumor maker levels normalized within 2 months of the initial treatment, and the peritoneal dissemination could no longer be detected by abdominal computed tomography(CT). The patient remained in clinical remission and maintained long-term survival of over 8 years. PMID:25131877

    A mesonephric adenocarcinoma of the cervix is a very rare tumor deriving from remnants of the mesonephric duct. Differential diagnosis from other cervical carcinomas is difficult and little is known regarding its biological behavior, prognosis, and the optimal management strategy. We present a case of a mesonephric adenocarcinoma of the cervix with a comprehensive review of the existing literature. In this case a 66-year-old woman presented with postmenopausal vaginal bleeding. She was diagnosed with a FIGO stage IIB mesonephric adenocarcinoma of the cervix and treated with neoadjuvant chemoradiotherapy and a Wertheim hysterectomy. The recovery from surgery was uneventful and the patient remains with no evidence of disease with 2 years of follow-up. PMID:27354991

    Cervical cancer is responsible for 10-15% of cancer-related deaths in women worldwide. The aetiological role of infection with high-risk human papilloma viruses (HPVs) in cervical carcinomas is well established. Previous studies have also implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS as well as several copy-number alterations in the pathogenesis of cervical carcinomas. Here we report whole-exome sequencing analysis of 115 cervical carcinoma-normal paired samples, transcriptome sequencing of 79 cases and whole-genome sequencing of 14 tumour-normal pairs. Previously unknown somatic mutations in 79 primary squamous cell carcinomas include recurrent E322K substitutions in the MAPK1 gene (8%), inactivating mutations in the HLA-B gene (9%), and mutations in EP300 (16%), FBXW7 (15%), NFE2L2 (4%), TP53 (5%) and ERBB2 (6%). We also observe somatic ELF3 (13%) and CBFB (8%) mutations in 24 adenocarcinomas. Squamous cell carcinomas have higher frequencies of somatic nucleotide substitutions occurring at cytosines preceded by thymines (Tp*C sites) than adenocarcinomas. Gene expression levels at HPV integration sites were statistically significantly higher in tumours with HPV integration compared with expression of the same genes in tumours without viral integration at the same site. These data demonstrate several recurrent genomic alterations in cervical carcinomas that suggest new strategies to combat this disease. PMID:24390348

    Cervical cerclage aims to strengthen not only the mechanical properties of the cervix, but also its immunological and anti-infectious functions. The demonstration of a strong interrelation between cervical insufficiency as well as decreased cervical length at endo-vaginal ultrasonography and infection has changed the indications cerclage. Actually we can distinguish three indications for cerclage: prophylactic, for obstetrical history; therapeutic, for shortened cervical length at ultrasonography in patients at risk and; emergency cerclage in case of threatening cervix at physical examination. The McDonald's technique is the most recommended. In case of failure, it is proposed to realize cerclage at a higher level on the cervix either by vaginal or abdominal route. PMID:26144289

  9. Spindle and kinetochore associated complex subunit 1 regulates the proliferation of oral adenosquamous carcinoma CAL-27 cells in vitro

    PubMed Central

    2013-01-01

    Background The prognosis of oral squamous cell carcinoma is very poor due to local recurrence and metastasis. This study explores the molecular events involved in oral carcinoma with the goal of developing novel therapeutic strategies. The mitotic spindle is a complex mechanical apparatus required for the accurate segregation of sister chromosomes during mitosis. Spindle and kinetochore associated complex subunit 1 (SKA1) is a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. In recent years, much attention has been focused on determining how SKA proteins interact with each other, as well as their biological role in cancer cells. However, the precise role of SKA1 in oral carcinoma remains unknown. Methods In order to investigate the role of SKA1 in oral cancer, we employed lentivirus-mediated shRNA to silence SKA1 expression in the CAL-27 human oral adenosquamous carcinoma cell line. Results Depletion of SKA1 in CAL-27 cells significantly decreased cell proliferation, as determined by MTT and colony formation assays. These results strongly demonstrate that reduced SKA1 protein levels may cause inhibition of tumor formation. The shRNA-mediated depletion of SKA1 also led to G2/M phase cell cycle arrest and apoptosis. Conclusion This is the first report to show that SKA1 plays an important role in the progression of oral adenosqamous carcinoma. Thus, silencing of SKA1 by RNAi might be a potential therapy for this disease. PMID:23962337

    The aim of the current retrospective study was to investigate the response of advanced cervical adenocarcinoma (AC) to definitive chemoradiotherapy. Uterine cervical cancer is one of the most common cancer types among females, with squamous cell carcinoma (SQCC) being the most prevalent histological type. The incidence of cervical AC and its variants has markedly increased in recent decades. The current understanding with regard to the treatment of cervical cancer has been established through studies in which the majority of the patients suffered from SQCC, while only a limited number of studies have focused on the treatment of AC. Therefore, the optimal treatment for uterine cervical AC remains unclear. In the present study, data were collected from the medical files of patients who were diagnosed with advanced uterine cervical AC and treated with chemoradiotherapy between 1998 and 2013. Data were also collected from a group of patients with SQCC for comparison with AC patients in terms of response and survival. A total of 68 uterine cervical cancer cases were included, including 29 AC patients and 39 SQCC patients. Compared with the SQCC subgroup, a higher number of AC patients required surgery following chemoradiotherapy due to a lack of response to the initial treatment (5% vs. 31%, respectively; P=0.0065). After a median follow-up period of 10 years, patients with AC exhibited shorter overall survival (7.4 years vs. 11 years for AC and SQCC groups, respectively; P=0.01). Differences in recurrence (40.7% vs. 34.4%; P=0.79) and disease-free interval (1.2 years vs. 2 years; P=0.11) were not statistically significant. The results indicated that cervical AC is less responsive to chemoradiotherapy compared with SQCC. PMID:26137148

    Radiation therapy is a proved treatment for cervical carcinoma; however, it destroys ovarian function and has been thought to ablate the endometrium. Estrogen replacement therapy is often prescribed for patients with cervical carcinoma after radiation therapy. A review of records of six teaching hospitals revealed 16 patients who had endometrial sampling for uterine bleeding after standard radiation therapy for cervical carcinoma. Fifteen patients underwent dilatation and curettage, and one patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy when a dilatation and curettage was unsuccessful. Six patients had fibrosis and inflammation of the endometrial cavity, seven had proliferative endometrium, one had cystic hyperplasia, one had atypical adenomatous hyperplasia, and one had adenocarcinoma. Although the number of patients who have an active endometrium after radiation therapy for cervical carcinoma is not known, this report demonstrates that proliferative endometrium may persist, and these patients may develop endometrial hyperplasia or adenocarcinoma. Studies have indicated that patients with normal endometrial glands have an increased risk of developing endometrial adenocarcinoma if they are treated with unopposed estrogen. Patients who have had radiation therapy for cervical carcinoma should be treated with estrogen and a progestational agent to avoid endometrial stimulation from unopposed estrogen therapy.

    Invasive squamous carcinoma of the cervix is preceded by a series of premalignant changes described as mild, moderate, or severe dysplasia, and carcinoma in situ. These premalignant states are identified by cervical cytology, diagnosed by colposcopy and if effectively treated, can prevent invasive squamous carcinoma of the cervix. Because of the apparent biological variation of the premalignant states, even the most aggressive cervical screening program cannot be expected to eliminate all invasive squamous cancer of the cervix. Optimal results of a cervical screening program will be achieved when all women under 35 years of age and sexually active have an annual cytological smear; the cytology is screened by a laboratory with high quality control; the patient's positive cytology is accurately assessed by an experienced colposcopist, and the premalignant lesion is effectively treated.

    These NCCN Clinical Practice Guidelines in Oncology for Cervical Cancer focus on early-stage disease, because it occurs more frequently in the United States. After careful clinical evaluation and staging, the primary treatment of early-stage cervical cancer is either surgery or radiotherapy. These guidelines include fertility-sparing and non-fertility-sparing treatment for those with early-stage disease, which is disease confined to the uterus. A new fertility-sparing algorithm was added for select patients with stage IA and IB1 disease.. PMID:23486458

    A 67-year-old woman with a history of lung adenocarcinoma presented with 3 weeks of redness, pain, swelling and skin changes in her right breast. Her vital signs and physical examination were within physiological limits except for the right breast. She had extensive red streaks radiating from the right nipple with peau d'orange appearance of her overlying skin. Her breast was tender on examination and did not have any associated cervical or axillary lymphadenopathy. Her mammography revealed thickening of the skin, increased parenchymal markings and shrinkage the breast. Multiple skin biopsies demonstrated moderately differentiated lung adenocarcinoma with lymphovascular invasion. The patient made an informed decision to undergo radiotherapy following discussion with her oncologist and breast surgeon. She succumbed to her illness 2 months after the diagnosis of metastasis to her breast. PMID:27587745

    Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

    Programmed death ligand 1 (PD L1) expression can reduce the immune response in both infectious diseases and cancers. We thus examined PD L1 expression in cervical intraepithelial neoplasias (CINs) and cancers since they each reflect infection by human papillomavirus (HPV). PD L1 protein was not evident by immunohistochemistry in histologically normal cervical epithelia (0/55) even when adjacent to CIN or cancer. PD L1 expression was much increased in CINs (20/21=95%) and cervical squamous cell cancer (56/70=80%) and localized to the dysplastic/neoplastic squamous cells and mononuclear cells, respectively. There was also a significant increase (each P<0.001) in PD L1 detection in mononuclear cells when comparing cervical squamous cell cancers to endometrial (22/115=19%) and ovarian adenocarcinomas (5/40=13%). Co-expression analyses showed that the primary inflammatory cell that contained PD L1 was the CD8+ lymphocyte that strongly concentrated around the dysplastic CIN cells and nests of invasive squamous cancer cells. These data show that PD L1 is a solid biomarker of productive HPV infection of the cervix and that it is significantly upregulated in both the carcinoma and surrounding inflammatory cells in cervical cancer when compared with other gynecologic malignancies. This suggests that anti-PD L1 therapy may have a role in the treatment of cervical cancer. PMID:26403783

    Standard treatment for invasive cervical cancer involves either radical surgery or radiotherapy. Childbearing is therefore impossible after either of these treatments. A fertility-sparing option, however, by radical trachelectomy has been shown to be effective, provided that strict criteria for selection are followed. Fertility rates are high, whereas recurrence is low, indicating that a more conservative approach to dealing with early small cervical tumours is feasible. Careful preoperative assessment by magnetic resonance imaging scans allows accurate measurement of the tumour with precise definition to plan surgery. This will ensure an adequate clear margin by wide excision of the tumour excising the cervix by radical vaginal trachelectomy with surrounding para-cervical and upper vaginal tissues. An isthmic cerclage is inserted to provide competence at the level of the internal orifice. A primary vagino-isthmic anastomosis is conducted to restore continuity of the lower genital tract. Subsequent pregnancies require careful monitoring in view of the high risk of spontaneous premature rupture of the membranes. Delivery by classical caesarean section is necessary at the onset of labour or electively before term. Over 1100 such procedures have been carried out vaginally or abdominally, resulting in 240 live births. Radical vaginal trachelectomy with a laparoscopic pelvic-node dissection offers the least morbid and invasive route for surgery, provided that adequate surgical skills have been obtained.

    Objectives To investigate the risks of invasive cervical cancer after detection of atypical glandular cells (AGC) during cervical screening. Design Nationwide population based cohort study. Setting Cancer and population registries in Sweden. Participants 3 054 328 women living in Sweden at any time between 1 January 1980 and 1 July 2011 who had any record of cervical cytological testing at ages 23-59. Of these, 2 899 968 women had normal cytology results at the first screening record. The first recorded abnormal result was atypical glandular cells (AGC) in 14 625, high grade squamous intraepithelial lesion (HSIL) in 65 633, and low grade squamous intraepithelial lesions (LSIL) in 244 168. Main outcome measures Cumulative incidence of invasive cervical cancer over 15.5 years; proportion of invasive cervical cancer within six months of abnormality (prevalence); crude incidence rates for invasive cervical cancer over 0.5-15.5 years of follow-up; incidence rate ratios compared with women with normal cytology, estimated with Poisson regression adjusted for age and stratified by histopathology of cancer; distribution of clinical assessment within six months after the abnormality. Results The prevalence of cervical cancer was 1.4% for women with AGC, which was lower than for women with HSIL (2.5%) but higher than for women with LSIL (0.2%); adenocarcinoma accounted for 73.2% of the prevalent cases associated with AGC. The incidence rate of invasive cervical cancer after AGC was significantly higher than for women with normal results on cytology for up to 15.5 years and higher than HSIL and LSIL for up to 6.5 years. The incidence rate of adenocarcinoma was 61 times higher than for women with normal results on cytology in the first screening round after AGC, and remained nine times higher for up to 15.5 years. Incidence and prevalence of invasive cervical cancer was highest when AGC was found at ages 30-39. Only 54% of women with AGC underwent histology assessment

    Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive malignant tumors with an overall 5-year survival rate of less than 4%. Surgical resection remains the only potentially curative treatment but is only possible for 15%-20% of patients with pancreatic adenocarcinoma. About 40% of patients have locally advanced nonresectable disease. In the past, determination of pancreatic cancer resectability was made at surgical exploration. The development of modern imaging techniques has allowed preoperative staging of patients. Institutions disagree about the criteria used to classify patients. Vascular invasion in pancreatic cancers plays a very important role in determining treatment and prognosis. There is no evidence-based consensus on the optimal preoperative imaging assessment of patients with suspected pancreatic cancer and a unified definition of borderline resectable pancreatic cancer is also lacking. Thus, there is much room for improvement in all aspects of treatment for pancreatic cancer. Multi-detector computed tomography has been widely accepted as the imaging technique of choice for diagnosing and staging pancreatic cancer. With improved surgical techniques and advanced perioperative management, vascular resection and reconstruction are performed more frequently; patients thought once to be unresectable are undergoing radical surgery. However, when attempting heroic surgery, a realistic approach concerning the patient’s age and health status, probability of recovery after surgery, perioperative morbidity and mortality and life quality after tumor resection is necessary.

    Aims A subset of colorectal carcinomas (CRCs) architecturally and cytologically resembles adenomatous change, making them difficult to diagnose on biopsy. This subset has not been well-characterized to date. Methods and results For 35 carcinomas with adenomatous-like areas (cytologic and surface architectural appearance that would be insufficient to warrant a diagnosis of adenocarcinoma if evaluated on biopsy), we recorded staging information, molecular data, clinical outcome, whether precursor adenoma was present, and whether prior biopsy had been diagnosed as malignant. Despite advanced T-category in 23 (66%) tumors, only 7 (20%) had nodal metastases, and only 5 patients (15%) developed distant metastases. Fifteen cases (43%) had been diagnosed as adenoma on biopsy. Twenty-one resections (60%) showed no residual associated adenoma, including 9 called adenoma on biopsy. Median follow-up was 44 months. Four patients (12%) died of disease; 22 were alive at last follow-up. KRAS mutation was seen in 14/24 (58%), and 4/17 (24%) were microsatellite-unstable. Patients had significantly improved survival compared to a cohort of patients with conventional well-differentiated CRC after controlling for age and stage (p=0.011). Conclusions Adenoma-like adenocarcinoma is an uncommon variant of CRC with a low rate of metastasis and good prognosis. Biopsy diagnosis of this lesion may be challenging. PMID:25913616

    Cervical cancer, a potentially preventable disease, remains the second most common malignancy in women worldwide. Human papillomavirus (HPV) is the single most important etiological agent in cervical cancer, contributing to neoplastic progression through the action of viral oncoproteins, mainly E6 and E7. Cervical screening programs using Pap smear testing have dramatically improved cervical cancer incidence and reduced deaths, but cervical cancer still remains a global health burden. The biomarker discovery for accurate detection and diagnosis of cervical carcinoma and its malignant precursors (collectively referred to as high-grade cervical disease) represents one of the current challenges in clinical medicine and cytopathology.

    We report 2 cases of primary vaginal mucinous adenocarcinoma arising in adenosis in nondiethylstilbestrol-exposed women, 1 with uterus didelphys. Both tumors exhibited morphologic and immunohistochemical features (MUC6 and/or HIK 1083 positivity) identical to the recently described cervical gastric-type adenocarcinoma, a subtype of mucinous adenocarcinoma that is non-human papillomavirus related and possibly related to adenoma malignum. Both neoplasms were intensely p53 positive, suggesting that TP53 mutation may be implicated in their development. We believe that the vaginal tumors arose from adenosis through atypical adenosis, as benign and atypical glands were present at the periphery of the neoplasms. In reporting these cases, we discuss atypical adenosis and other types of non-diethylstilbestrol-associated vaginal adenocarcinomas. At least 9 other examples of primary vaginal, or more uncommonly cervical, adenocarcinomas arising in non-diethylstilbestrol-exposed women with congenital genitourinary malformations have been reported, suggesting a probable causal association between congenital malformation, vaginal adenosis, and vaginal adenocarcinoma.

    Gastric and esophageal adenocarcinomas are one of the main causes of cancer-related death worldwide. While the incidence of gastric adenocarcinoma is decreasing, the incidence of gastroesophageal junction adenocarcinoma is rising rapidly in Western countries. Considering that surgical resection is currently the major curative treatment, and that the 5-year survival rate highly depends on the pTNM stage at diagnosis, gastroesophageal adenocarcinoma management is very challenging for oncologists. Several treatment strategies are being evaluated, and among them systemic chemotherapy, to decrease recurrences and improve overall survival. The MAGIC and FNCLCC-FFCD trials showed a survival benefit of perioperative chemotherapy in patients with operable gastric and lower esophageal cancer, and these results had an impact on the European clinical practice. New strategies, including induction chemotherapy followed by preoperative chemoradiotherapy, targeted therapies in combination with perioperative chemotherapy and the new cytotoxic regimens, are currently assessed to improve current standards and help developing patient-tailored therapeutic interventions.

    Many reports have shown a link between human papillomavirus (HPV) and cervical squamous neoplasia. However, the association of HPV with cervical adenocarcinoma has been studied less extensively. The authors evaluated the presence of HPV-DNA in 106 patients with adenocarcinoma of the uterine cervix by in situ hybridization, using {sup 35}S-labeled probes for HPV 16 DNA and HPV 18 DNA. The overall prevalence of HPV-DNA was 18% (19 of 106). HPV 16 was present in 2 (2%) cases, HPV 18 was observed in 15 (14%) cases, and both HPV 16 and HPV 18 were found in 2 (2%) cases. There was a correlation between HPV-DNA positivity and tumor stage (P less than 0.01) and tumor size (P less than 0.05), but there was no relationship between HPV-DNA positivity and tumor differentiation, proliferation (S-phase fraction), ploidy, lymph node metastases, or five-year survival rate. These results suggest that HPV 18 DNA is associated with cervical adenocarcinoma but the presence of HPV 18 has no influence on overall survival.

    Charts of 36 patients with clinical stage II endometrial adenocarcinoma over ten years were reviewed. All were staged before any treatment, in accordance with International Federation of Gynecology and Obstetrics (FIGO) guidelines. Although details of treatment varied, two main protocols were used. Fourteen patients were treated with the standard protocol involving external whole-pelvis radiation, followed by intracavitary cesium and then hysterectomy. In 1981, a modified protocol was introduced, which called for a hysterectomy immediately following intrauterine and vaginal cesium. External radiation therapy was given only to those patients found to have deep myometrial invasion or cervical involvement. Of 14 patients treated by this protocol, seven had no surgical indication for postoperative external radiation. There was no increase in recurrence in these patients, and the five-year survival rate was 76% for patients treated with the modified protocol compared with 65% for those who had standard therapy. Morbidity related to external radiation therapy occurred in two patients with the standard protocol and one patient who received pelvic radiation on the modified protocol.

Highly selected patients with obstructing neoplasms of the esophagus and airway can be palliated and sometimes cured by this aggressive surgical approach. Fatal hemorrhage from pressure or exposure of the innominate artery is avoided by elective division of the artery (preoperative angiograms and intraoperative electroencephalographic control are essential), using the omentum to separate the trachea and great vessels, and removal of a bony plaque of chest wall to allow a well-vascularized bipedicled skin flap to drop into the mediastinum for the tracheocutaneous anastomosis. Eighteen exenterations were performed. Mediastinal tracheostomy was performed in 14 patients and division of the innominate artery was performed in 7. Esophageal replacement was predominantly with the left colon. Complications include esophageal leak (2 patients), stomal separation (2), transient hemiplegia (1), colonic obstruction by substernal tunnel (1), and need for prolonged mechanical ventilation (4). There was a single operative death. Postoperative survival was disease dependent. All patients achieved an excellent airway and relief from dysphagia. PMID:2178569

  18. Fine needle aspiration cytology of cervical lymph node involvement by ovarian serous borderline tumor

    PubMed Central

    Chen, Longwen; Butler, Kristina A.; Bell, Debra A.

    2016-01-01

    Serous borderline tumor (SBT) involving a cervical lymph node is extremely rare. In addition, fine needle aspiration (FNA) cytology of the involved cervical lymph node shares tremendous morphologic similarity with other low-grade papillary carcinomas. Thus, it can be easily misdiagnosed as metastatic carcinoma. A 42-year-old female had a history of bilateral SBT and postbilateral salpingo-oophorectomy. She presented with left cervical lymphadenopathy 6 months later. FNA cytology showed a low-grade papillary neoplasm with psammoma bodies. Needle core biopsy along with immunostains was diagnostic of cervical lymph node involvement (LNI) of SBT. although extremely rare, cervical LNI can be found in patients with SBTs. FNA cytology, sometimes, is indistinguishable from metastatic papillary adenocarcinoma. Cell block or needle core biopsy is essential to make the correct diagnosis.

  19. Differentiating bronchioloalveolar carcinoma from adenocarcinoma.

    The recognition of bronchioloalveolar carcinoma (BAC) as distinct from adenocarcinoma of the lung, is controversial. Using strict pathologic criteria, 43 consecutive patients with BAC were matched by year of diagnosis and compared with a similar number of patients with adenocarcinoma, and for contrast, with those with squamous and oat cell carcinoma of the lung. We demonstrated that BAC is not sex related, and is not as smoking related as the other neoplasms. Unlike epidermoid carcinoma, BAC does not show a predilection for those occupations requiring manual labor. Also, BAC is frequently distinguishable radiologically from the other three by being smaller and peripheral. A pleural tag and an air bronchogram in a mass are rather specific, and BAC is less likely to have large airway involvement and adenopathy. The percentage of patients who were free of tumor after 2 yr was greater in the BAC group than in the others, but the overall survival rate between the BAC group and the adenocarcinoma group was not. Based on inter-observer variability, there is some overlap pathologically between these 2 groups. However, when the overlap between the adenocarcinoma and the BAC groups is compared with that between the adenocarcinoma and the squamous cell carcinoma groups, the difference is not significant. We conclude that BAC should be considered a distinct clinical entity. PMID:6278997

    Pemetrexed-containing chemotherapy has shown promise in the treatment of non-small-cell lung cancer (NSCLC). However, although adenosquamous cell lung cancer (ASCLC) is a type of NSCLC, the availability of studies investigating its response to pemetrexed-containing chemotherapy is limited. A 66-year-old woman was referred to Mito Medical Center, University of Tsukuba with hemoptysis and a chest computed tomography (CT) scan revealed a large cavitary mass in the lower lobe of the left lung. The patient underwent left lower lobectomy and mediastinal lymph node dissection. The tumor was staged as pT2bN2M0. An epidermal growth factor receptor (EGFR) exon 19 deletion was identified in the adenocarcinomatous as well as the squamous cell carcinomatous components. Despite gefitinib therapy for pulmonary metastases, the patient developed cavitary metastases in both lungs. Therefore, treatment with pemetrexed-containing chemotherapy was initiated. A chest CT scan revealed significant regression of the metastatic lesions in both lungs, with thinning of the walls. The patient remains well and recurrence-free 19 months after the initiation of pemetrexed-containing chemotherapy. Therefore, the clinical response of EGFR mutation-positive ASCLC to pemetrexed-containing chemotherapy was promising, suggesting pemetrexed to be one of the key drugs for this subset of ASCLC patients.

    Libya is a country with a low population, listed under the EMRO. Using registers and patient records from a major primary oncology clinic, data was gathered from Libyan cervical cancer patients and various parameters were studied across 9 years. Out of 4,090 female cancer cases during the study period, 1.8% were cervical cancer (n = 74). The average age of presentation was 53 years, with most of the cases (60%, n = 44) being premenopausal. Approximately 65% (n = 48) of cervical cancer patients are diagnosed at later stages (i.e. stages III and IV). The majority of these cases are squamous cell carcinoma (83.8%, n = 62), while 16.2% (n = 12) were found to be adenocarcinoma. Patients with squamous cell carcinoma presented at later stages more often than those with adenocarcinoma. Human papilloma virus was strongly implicated in cervical cancer, with 94% (n = 63) of those who were tested being positive for HPV-16 (82.5%, n = 52) and HPV-18 (12.7%, n = 8). Diagnosis was most frequently made through biopsy (97.3%, n = 72) as opposed to Pap smears (2.7%, n = 2). Most Libyan patients were put through chemotherapy (75%, n = 55) and triple therapy (surgery with combined chemotherapy and radiotherapy) was the most common (38%, n = 28) modality of treatment. Comparisons were made between Libya and other nations, either in the developed world or neighbouring countries. The major problem of cervical cancer in Libya is delayed presentation and hence, all the recommendations focus on increased awareness for the populace, implementation of a national cancer control plan and a national screening programme.

    We report a case of Peutz-Jeghers syndrome (PJS) in a 33-year-old female patient with synchronous uterine cervical minimal deviation adenocarcinoma (MDA) and gastric type adenocarcinoma (GTA). The patient was diagnosed with PJS at the age of 10. At the time of consultation, she complained of watery discharge. Magnetic resonance imaging of the pelvis showed a poorly circumscribed mass in the uterine cervix. Histologically, both MDA and GTA components, as well as their transitional area, were observed. Both components were diffusely positive for MUC6, CK7 and, robustly, for p16. Moreover, the components were negative for ER, PgR and CEA, while HIK1083 and CK20 positive cells were found focally. Ki-67 labeling index in the MDA component was 5% while that in the GTA component was 50%. This case of GTA accompanied by MDA in a patient with PJS is distinct from the single previously-reported comparable case of which we are aware, with respect to the overexpression of p16 protein, an event considered rare in these tumors, and the continuity between the MDA and GTA components. This continuity favors the hypothesis that GTA arises from the dedifferentiation of MDA. PMID:26191312

    Spinal chordomas are more often located on the midline and are associated with marked destruction of the vertebral bodies. We report a rare case of large cervical (C2-C3) right lateral paravertebral chordoma extending into the spinal canal through a very enlarged intervertebral foramen. The tumor was initially diagnosed as a mucous adenocarcinoma on a percutaneous needle biopsy. However, the neuroradiological features, including the well-defined tumor margins, the regular and sclerosing lytic bone changes with regular enlargement of the intervertebral C2-C3 foramen, were in favor of a more slowly growing lesion, such as schwannoma or neurofibroma. At surgery a well-demarcated capsulated tumor involving the nerve root was partially resected. Histology was in favor of a low-grade chordoma (Ki-67/MIB-1<1%). Postoperative proton beam therapy was also performed. The differential neuroradiological diagnosis is discussed. PMID:23859247

    A 48 year-old female presented to her primary care physician with a two-month history of neck pain with negative cervical spine x-rays. During that office visit, the patient was noted to be tachycardic with EKG revealing ST depressions, which led to hospital admission. Acute coronary syndrome was ruled out, however, persistent neck pain warranted inpatient MRI of the cervical spine, which revealed a cervical spine lesion. Extensive investigation and biopsy ultimately confirmed stage IV pancreatic adenocarcinoma with metastases to the bone, liver, and likely lung. In the literature, the findings of a primary metastatic site being bone is rare with only a few case reports showing vertebral or sternal metastasis as the first clinical manifestation of pancreatic cancer. The uniqueness of this case lies in the only presenting complaint being cervical spine pain in the setting of extensive metastases to the liver, bone, and likely lung. PMID:26890294

    To investigate the clinicopathological features, management and prognosis of villoglandular papillary adenocarcinoma (VGPA) of the uterine cervix, the current study presents 4 cases of VGPA of the uterine cervix. The median age of the patients was 55 years (range, 47–70 years), with all 4 patients presenting with stage Ib disease. Human papillomavirus (HPV) infection was detected in 3 patients; this was mainly HPV-16. No history of oral contraceptive use was found in these cases. While 2 of the patients underwent a radical hysterectomy with bilateral salpingo-oophorectomy plus bilateral pelvic lymphadenectomy, 1 patient underwent a radical hysterectomy with bilateral pelvic lymphadenectomy and the remaining patient received a simple total hysterectomy plus post-operative radiotherapy. Of these patients, only 1 had been correctly diagnosed pre-operatively. In 2 patients, the biopsy results had been interpreted as cervical adenocarcinoma, and in the third, the biopsy result was of cervical intraepithelial neoplasia. All 4 patients presented with cervical wall invasion, including invasion of the inner two-thirds in 1 patient. No lymphovascular space invasion or lymph node metastasis was detected. The follow-up time ranged from 49 to 83 months (median, 64 months), and the patients are currently alive and well, with no evidence of recurrent disease. Taking these results as a whole, VGPA is an uncommon type of cervical adenocarcinoma, characterized by its excellent prognosis. HPV infection is associated with the molecular pathogenesis of VGPA, while oral contraceptive use can be excluded. As the disease has a low pre-operative diagnostic accuracy, frequent cervical wall invasion and concomitant lesions, conservative treatment strategies should be carefully considered. PMID:26870293

    Müllerian carcinosarcoma is currently regarded as a metaplastic (sarcomatous) carcinoma. Only five cases of pure ovarian adenocarcinoma recurring as carcinosarcoma have been documented in the literature. There are no documented cases of endometrial adenocarcinoma recurring as metaplastic carcinoma. We report of a case of endometrial adenocarcinoma, endometrioid type, recurring as metaplastic carcinoma showing sarcomatous differentiation. The tumor evolution in this case supports the prevailing opinion that Müllerian carcinosarcomas are derived from carcinomas and represent tumor progression. PMID:18412798

  12. Seminal plasma induces the expression of IL-1α in normal and neoplastic cervical cells via EP2/EGFR/PI3K/AKT pathway

    PubMed Central

    2014-01-01

    Background Cervical cancer is a chronic inflammatory disease of multifactorial etiology usually presenting in sexually active women. Exposure of neoplastic cervical epithelial cells to seminal plasma (SP) has been shown to promote the growth of cancer cells in vitro and tumors in vivo by inducing the expression of inflammatory mediators including pro-inflammatory cytokines. IL-1α is a pleotropic pro-inflammatory cytokine induced in several human cancers and has been associated with virulent tumor phenotype and poorer prognosis. Here we investigated the expression of IL-1α in cervical cancer, the role of SP in the regulation of IL-1α in neoplastic cervical epithelial cells and the molecular mechanism underlying this regulation. Methods and results Real-time quantitative RT-PCR confirmed the elevated expression of IL-1α mRNA in cervical squamous cell carcinoma and adenocarcinoma tissue explants, compared with normal cervix. Using immunohistochemistry, IL-1α was localized to the neoplastically transformed squamous, columnar and glandular epithelium in all cases of squamous cell carcinoma and adenocarcinomas explants studied. We found that SP induced the expression of IL-α in both normal and neoplastic cervical tissue explants. Employing HeLa (adenocarcinoma) cell line as a model system we identified PGE2 and EGF as possible ligands responsible for SP-mediated induction of IL-1α in these neoplastic cells. In addition, we showed that SP activates EP2/EGFR/PI3kinase-Akt signaling to induce IL-1α mRNA and protein expression. Furthermore, we demonstrate that in normal cervical tissue explants the induction of IL-1α by SP is via the activation of EP2/EGFR/PI3 kinase-Akt signaling. Conclusion SP-mediated induction of IL-1α in normal and neoplastic cervical epithelial cells suggests that SP may promote cervical inflammation as well as progression of cervical cancer in sexually active women.

    Barrett’s esophagus (BE) is a precursor of esophageal adenocarcinoma and is associated with gastroesophageal reflux disease, which is often preceded by a hiatal hernia. We describe a case of esophageal adenocarcinoma arising in long-segment BE (LSBE) associated with a hiatal hernia that was successfully treated with a laparoscopic transhiatal approach (LTHA) without thoracotomy. The patient was a 42-year-old male who had previously undergone laryngectomy and tracheal separation to avoid repeated aspiration pneumonitis. An ulcerative lesion was found in a hiatal hernia by endoscopy and superficial esophageal cancer was also detected in the lower thoracic esophagus. The histopathological diagnosis of biopsy samples from both lesions was adenocarcinoma. There were difficulties with the thoracic approach because the patient had severe kyphosis and muscular contractures from cerebral palsy. Therefore, we performed subtotal esophagectomy by LTHA without thoracotomy. Using hand-assisted laparoscopic surgery, the esophageal hiatus was divided and carbon dioxide was introduced into the mediastinum. A hernial sac was identified on the cranial side of the right crus of the diaphragm and carefully separated from the surrounding tissues. Abruption of the thoracic esophagus was performed up to the level of the arch of the azygos vein via LTHA. A cervical incision was made in the left side of the permanent tracheal stoma, the cervical esophagus was divided, and gastric tube reconstruction was performed via a posterior mediastinal route. The operative time was 175 min, and there was 61 mL of intra-operative bleeding. A histopathological examination revealed superficial adenocarcinoma in LSBE. Our surgical procedure provided a good surgical view and can be safely applied to patients with a hiatal hernia and kyphosis. PMID:26269688

    Acrokeratosis paraneoplastica, or Bazex syndrome, is one of the paraneoplastic syndromes. The characteristic skin lesions include palmoplantar keratoderma, psoriasiform skin lesions, hyperpigmentation, and nail dystrophy. The most common associated neoplasms are squamous cell carcinoma of the upper respiratory tract and other kinds of tumors with cervical lymph node metastasis. A 63-year-old woman presented with an 11 month history of hyperkeratotic lesions on the palms and soles. Ten months before she had been diagnosed with adenocarcinoma of the colon and undergone a left hemicolectomy. We report a case of acrokeratosis paraneoplastica associated with colon cancer which persisted after removal of the primary cancer, but resolved with topical tretinoin treatment.

    In a 29-year-old woman with the Peutz-Jeghers syndrome (PJS), an extremely well differentiated adenocarcinoma (adenoma malignum) of the uterine cervix was detected. The cervical lesion consisted of a polypoid mass, measuring 3.5 cm in greatest diameter, composed of extremely well differentiated tubules resembling those of the endocervical glands, yet containing a few Paneth cells. Immunohistochemical stains displayed cytoplasmic carcinoembryonic antigen in this tumor. The ovaries had no apparent abnormality. The diagnosis of the PJS was based on the presence of numerous hamartomatous polyps of the rectum and cutaneous pigmentation around the lips, fingers, and toes. The patient underwent a simple total hysterectomy and was subsequently treated with chemotherapy. In an 11 year follow-up, there has been no recurrence of the cervical tumor and she is currently well. The clinicohistopathologic differences of this cervical tumor in patients with and without PJS are briefly discussed. PMID:4055223

    2002-12-01

    Decreased E-cadherin expression permits dissociation and widespread dissemination of gastric adenocarcinoma cells. We studied the relationship between paranuclear E-cadherin distribution and the histopathologic characteristics of gastric adenocarcinomas. E-cadherin immunostains of 173 gastric adenocarcinoma sections revealed paranuclear; punctate to vesicular staining in 18% (16/87) of the intestinal-type adenocarcinomas, 30% (17/56) of the diffuse-type adenocarcinomas, and 30% (9/30) of the mired adenocarcinomas. These data suggest that in some gastric adenocarcinomas, there is a defect in transport of E-cadherin to the cell surface, which may prevent intercellular adhesion and encourage dissemination. Of 34 cancers with paranuclear E-cadherin staining, 20 (59%) had paranuclear staining within the nonneoplastic epithelium, but only 22.0% of 100 carcinomas with absent or membranous E-cadherin staining were accompanied by morphologically benign epithelium with paranuclear E-cadherin. In surface epithelium, paranuclear E-cadherin staining colocalized with Griffonia simplicifolia lectin II in the Golgi apparatus. The presence of paranuclear E-cadherin in cancer-associated benign epithelium suggests that the alteration in the E-cadherin molecule responsible for the paranuclear distribution may be an early change in gastric adenocarcinoma progression.

    We describe the case of a presumed metastatic adenocarcinoma discovered in the conjunctival limbus of a 75-year-old male with a history of prostate adenocarcinoma. After an initial clinical diagnosis of pinguecula and unsuccessful topical steroid therapy, the lesion was excised and sent for pathological evaluation and special staining. The histopathological evaluation was consistent with a diagnosis of adenocarcinoma, without evidence of lacrimal tissue. Surprisingly, results from special staining were most consistent with lung adenocarcinoma rather than that from a prostate origin. Systemic radiographic evaluation did not locate the primary tumour, and the patient did not present with any symptoms consistent with malignancy. Watchful waiting was chosen as the therapeutic strategy to manage the patient. This is the first report of an adenocarcinoma, likely metastatic, at the conjunctival limbus. PMID:27190113

    An 8-year-old neutered female Labrador retriever was presented with a 3-year history of intermittent haematuria. Ultrasonographic evaluation of the urinary bladder revealed a 2 × 3 × 0.5 cm intraluminal mass arising at the dome. The mass was excised via partial cystectomy. Histopathological examination revealed neoplastic epithelial cells arranged in sheets, irregularly-branching tubules and acini within a fibrovascular stroma. Neoplastic cells were cuboidal to polygonal with abundant foamy amphophilic cytoplasm, typically with a single, large, clear intracytoplasmic vacuole and eccentric nucleus ('signet ring' cells). Neoplastic tubules were often ectatic and contained abundant mucin. Immunohistochemically, the neoplastic cells had weak, cytoplasmic immunoreactivity for cytokeratin 7 and rare, but strong, nuclear immunoreactivity for CDX2. Based on the cellular morphology, immunolabelling characteristics and anatomical location, a diagnosis of adenocarcinoma of urachal origin was made. To the authors' knowledge, this is the first reported case of urachal adenocarcinoma in a dog. PMID:27009748

The analysis included causes and frequency of cervical spine fractures, their most common localisation, architecture of bone destruction and their influence on cervical cord. The most common cause of cervical spine injury was motor vehicle accidents. We examined 82 specimens with traumatic fractures of cervical spine obtained from accident victims. About half of the injuries occurred in upper cervical spine. The most common fracture localisation was C2 with dens fracture as the most frequent injury. The most common spinal cord lesion was complete rupture mainly at the upper cervical spine level. PMID:14564791

    Tarlov (perineural) cysts of the nerve roots are common and usually incidental findings during magnetic resonance imaging of the lumbosacral spine. There are only a few case reports where cervical symptomatic perineural cysts have been described in the literature. We report such a case where a high cervical perineural cyst was masquerading as a cervical spinal tumor. PMID:24761204

    Programmed death-ligand 1 (PD-L1) is expressed in various immune cells and tumor cells, and is able to bind to PD-1 on T lymphocytes, thereby inhibiting their function. At present, the PD-1/PD-L1 axis is a major immunotherapeutic target for checkpoint inhibition in various cancer types, but information on the clinical significance of PD-L1 expression in cervical cancer is largely lacking. Here, we studied PD-L1 expression in paraffin-embedded samples from two cohorts of patients with cervical cancer: primary tumor samples from cohort I (squamous cell carcinoma, n=156 and adenocarcinoma, n=49) and primary and paired metastatic tumor samples from cohort II (squamous cell carcinoma, n=96 and adenocarcinoma, n=31). Squamous cell carcinomas were more frequently positive for PD-L1 and also contained more PD-L1-positive tumor-associated macrophages as compared with adenocarcinomas (both P<0.001). PD-L1-positive tumor-associated macrophages were found to express CD163 and/or CD14 by triple fluorescent immunohistochemistry, demonstrating an M2-like phenotype. Interestingly, disease-free survival (P=0.022) and disease-specific survival (P=0.046) were significantly poorer in squamous cell carcinoma patients with diffuse PD-L1 expression as compared with patients with marginal PD-L1 expression (i.e., on the interface between tumor and stroma) in primary tumors. Disease-specific survival was significantly worse in adenocarcinoma patients with PD-L1-positive tumor-associated macrophages compared with adenocarcinoma patients without PD-L1-positive tumor-associated macrophages (P=0.014). No differences in PD-L1 expression between primary tumors and paired metastatic lymph nodes were detected. However, PD-L1-positive immune cells were found in greater abundance around the metastatic tumors as compared with the paired primary tumors (P=0.001 for squamous cell carcinoma and P=0.041 for adenocarcinoma). These findings point to a key role of PD-L1 in immune escape of cervical cancer

    We conducted a hospital-based case-control study in Algiers, Algeria. A total of 198 cervical carcinoma (CC) cases (including 15 adeno- and adenosquamous carcinomas) and 202 age-matched control women were included. Human papillomavirus (HPV) DNA in cervical cells was evaluated using a PCR assay. Odds ratios and corresponding confidence intervals were computed by means of unconditional multiple logistic regression models. HPV infection was detected in 97.7% of CC cases and 12.4% of control women (OR = 635). Nineteen different HPV types were found. HPV 16 was the most common type in both CC cases and control women, followed by HPV 18 and 45. Twelve types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 66 and 73) were found as single infections in CC cases. Multiple HPV infections did not show a higher odds ratio for CC than single infections. In addition to HPV infection, husband's extramarital sexual relationships with other women (OR = 4.8) or prostitutes (OR = 3.2), residing in a rural environment for most of one's life (OR = 4.9) and indicators of poor sanitation or poor hygiene were the strongest risk factors for CC. Oral contraceptive use was unrelated to CC risk, while multiparity emerged as a significant risk factor after adjustment for sexual habits. Intrauterine device users showed a lower CC risk than nonusers. The role of major risk factors, except inside toilet, was confirmed in the analysis restricted to HPV-positive women. The distribution of HPV types in CC cases and control women in Algeria is more similar to the one found in Europe than the one in sub-Saharan Africa, where HPV 16 is less prevalent. A vaccine against HPV 16 and 18 may be effective in more than 3/4 of CCs in Algeria. PMID:15455386

    Molecular-targeted therapy has not been established in non-adenocarcinoma lung cancer (non-AdLC), as no targets that affect the clinical efficacy of molecular-targeted drugs have yet been identified. In this study, we investigated the frequency of genetic variations in discoidin domain receptor 2 (DDR2), v-raf murine sarcoma viral oncogene homolog B1 (BRAF), epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) in non-AdLC patients, in order to evaluate the possibility of genetic mutations in these genes being used as therapeutic targets for the treatment of patients with non-AdLC. For this purpose, we enrolled 150 non-AdLC patients who had undergone surgery at the Gunma University Hospital between December, 2003 and December, 2012. Genetic mutations in the EGFR, KRAS, DDR2 and BRAF genes were detected by a sequencing method or probe assay using DNA derived from cancer tissues. No somatic mutations in DDR2 or BRAF were detected in non-AdLC patients. Conversely, genetic mutations in EGFR exon 19 were found in 3 squamous cell carcinoma (SCC) and 3 adenosquamous carcinoma patients, whereas KRAS codon 12 mutations were also found in 3 SCC patients and 1 large-cell neuroendocrine carcinoma patient. EGFR and KRAS mutations were mutually exclusive. This study indicated that, although DDR2 and BRAF mutations may only rarely be used as therapeutic targets, EGFR and KRAS mutations may represent candidate therapeutic targets, at least in the non-AdLC patients investigated.

    Pancreatic ductal adenocarcinoma is characterized by a poor prognosis and a low median survival, despite improvements observed for many other solid tumours. Intensive research efforts have been undertaken during the last decades to discover new prognostic and treatment predictive biomarkers for pancreatic ductal adenocarcinoma. The mainstay of medical treatment for the disease has been the well-tolerated nucleoside analogue, gemcitabine. The only targeted agent currently used in pancreatic ductal adenocarcinoma patients is the epithelial growth factor receptor inhibitor erlotinib in combination with gemcitabine. Recently, treatment regimens such as a combination of fluorouracil-leucovorin-irinotecan-oxaliplatin (FOLFIRINOX) and the combination of nab-paclitaxel with gemcitabine have been introduced for metastatic pancreatic ductal adenocarcinoma. Although these treatment regimens significantly improve survival of patients, there are no good predictive biomarkers available that can be used to identify who would benefit most from them. Therefore, the search for predictive biomarkers that would facilitate personalization of chemotherapy is highly relevant. PMID:26769569

    Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed by cytology. Consequently, there is a need for a better screening test. The insight that infection with high-risk human papillomavirus (hrHPV) is the causal agent of cervical cancer and its precursors has led to the development of molecular tests for the detection of hrHPV. Strong evidence now supports the use of hrHPV testing in the prevention of cervical cancer. In this review, we will discuss the arguments in favor of, and concerns on aspects of implementation of hrHPV testing in primary cervical cancer screening, such as the age to start hrHPV-based screening, ways to increase screening attendance, requirements for candidate hrHPV tests to be used, and triage algorithms for screen-positive women.

    Symptomatic adjacent segment degeneration of the cervical spine remains problematic for patients and surgeons alike. Despite advances in surgical techniques and instrumentation, the solution remains elusive. Spurred by the success of total joint arthroplasty in hips and knees, surgeons and industry have turned to motion preservation devices in the cervical spine. By preserving motion at the diseased level, the hope is that adjacent segment degeneration can be prevented. Multiple cervical disc arthroplasty devices have come onto the market and completed Food and Drug Administration Investigational Device Exemption trials. Though some of the early results demonstrate equivalency of arthroplasty to fusion, compelling evidence of benefits in terms of symptomatic adjacent segment degeneration are lacking. In addition, non-industry-sponsored studies indicate that these devices are equivalent to fusion in terms of adjacent segment degeneration. Longer-term studies will eventually provide the definitive answer. PMID:24353955

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    Objective To determine the feasibility of cervical conization and sentinel lymph node (SLN) mapping as a fertility-sparing strategy to treat stage I cervical cancer and estimate the tumor margin status needed to achieve no residual carcinoma in the cervix. Methods We identified all patients who desired fertility-preservation and underwent SLN mapping with cervical conization for stage I cervical cancer from 9/2005–8/2012. Relevant demographic, clinical, and pathological information was collected. Results Ten patients were identified. Median age was 28 years (range,18–36). None of the patients had a grossly visible tumor. The initial diagnosis of invasive carcinoma was made either on a loop electrosurgical excision procedure (LEEP) or cone biopsy. All patients underwent preoperative radiologic evaluation (MRI and PET-CT). None of the patients had evidence of gross tumor or suspicion of lymph node metastasis on imaging. Stage distribution included: IA1 with lymphovascular invasion, 7(70%); and microscopic IB1, 3(30%). Histology included: squamous cell carcinoma, 8(80%); adenocarcinoma, 1(10%); and clear cell carcinoma, 1(10%). Nine patients underwent repeat cervical conization with SLN mapping, and 1 patient underwent post-conization cervical biopsies and SLN mapping. None of the patients had residual tumor identified on the final specimen. The median distance from the invasive carcinoma to the endocervical margin was 2.25mm, and the distance from the invasive carcinoma to the ectocervical margin was 1.9mm. All collected lymph nodes were negative for metastasis. After a median follow-up of 17 months (range,1–83), none of the patients were diagnosed with recurrent disease and 3 patients (30%) achieved pregnancy. Conclusion Cervical conization and SLN mapping appears to be an acceptable treatment strategy for selected patients with small-volume stage I cervical cancer. Tumor clearance of ≥2mm appears to correlate well with no residual on repeat conization. A

    The aim of the study is to investigate the prevalence of high-risk human papillomavirus (hr-HPV) genotypes among Han women with high-grade cervical lesions in Beijing, China.Cervical cell specimens from patients with histopathologically confirmed cervical lesions at 7 hospitals in Beijing were examined with a validated HPV kit for 13 hr-HPV genotypes during the study period. The patients were divided into a low-grade cervical lesions group (cervical intraepithelial neoplasia grade 1, CIN1) and a high-grade cervical lesions group (CIN2+, including cervical intraepithelial neoplasia grade 2, CIN2; cervical intraepithelial neoplasia grade 3, CIN3; squamous cervical cancer, SCC; and adenocarcinoma of the cervix, ACC) based on the histopathology results.A total of 2817 eligible patients were enrolled, including 610 cases identified as CIN1 and 2207 as CIN2+. The hr-HPV positive rates in the CIN1 and CIN2+ groups were 78.2% (477/610) and 93.3% (2060/2207), respectively. The most frequently detected genotypes were HPV16, 58, 52 and18 in the CIN1 group and HPV16, 58, 33, and 52 in the CIN2+ group, in descending order of prevalence. In addition, the prevalence of HPV18 among the patients with ACC was 28.6% (14/49), significantly >7.2% (54/752) prevalence among the SCC patients (P < 0.001). Additionally, significantly more women in the CIN2+ group had multiple infections compared with those in the CIN1 group (38.1% and 24.9%, respectively; P < 0.001). However, as the cervical lesion grade increased, the prevalence of multiple hr-HPV infections gradually deceased to 44.2% in the CIN2 patients, 36.7% in the CIN3 patients, and 35.3% in the cervical cancer (CC) patients, which included SCC and ACC patients. In cases of multiple hr-HPV infections in the CIN2+ group, double infections accounted for ∼76.6%, and HPV16+58, HPV16+52, and HPV16+18 were the most common combinations, in descending order. The most frequent combination for triple infections was HPV16+58+31, with

    Abstract Several uncommon primary pancreatic tumors, inflammatory conditions, metastasis to the pancreas and peripancreatic masses can mimic the appearance of pancreatic ductal adenocarcinoma (PDA). Differentiation between these lesions and PDA can be challenging, due to the overlap in imaging features; however, familiarity with their typical imaging features and clinical presentation may be helpful in their differentiation, as in some cases, invasive diagnostic tests or unnecessary surgery can be avoided. The different pathologies that can mimic PDA include inflammatory conditions such as the various forms of pancreatitis (chronic-focal mass-forming, autoimmune and groove pancreatitis), pancreatic neuroendocrine tumors, solid pseudopapillary tumors, metastasis (solid non-lymphomatous and hematologic), congenital variants (annular pancreas), as well as peripancreatic lesions (accessory spleen, adrenal masses, duodenal masses, lymph nodes and vascular lesions), and certain rare pancreatic tumors (e.g., acinar cell tumors, solid serous tumors, hamartoma and solitary fibrous tumors). The clinical presentation and imaging features of the most commonly encountered mimics of PDA are discussed in this presentation with representative illustrations. PMID:24060833

    Abstract As whether Chlamydia trachomatis infection increases the risk of cervical cancer is controversial in the literature, we performed a meta-analysis. Based on a comprehensive search of publications in the Medline, Cochrane, and EMBASE databases, we identified and extracted data from all relevant articles examining C. trachomatis infection and the risk of cervical cancer. The quality of each included study was assessed according to the 9-star Newcastle–Ottawa scale. The strength of association between the C. trachomatis and risk of cervical cancer was estimated by odds ratio (OR) and 95% confidence intervals (CIs). This review was registered at PROSPERO with registration No. CRD42014015672. A total of 22 studies with 4291 cervical cancer cases and 7628 controls were identified. Overall, C. trachomatis was significantly linked to increased cervical cancer risk in prospective studies (OR = 2.21, 95% CI: 1.88–2.61, P < 0.001), as well as in retrospective studies (OR = 2.19, 95% CI: 1.74–2.74, P < 0.001). Additionally, with a multivariate logistic regression analysis adjusted for HPV and age, C. trachomatis infection was identified as an independent predictor of cervical cancer in 11 studies (OR = 1.76, 95% CI: 1.03–3.01, P = 0.04). Coinfection of human papilloma virus and C. trachomatis has a higher risk of cervical cancer (OR = 4.03, 95% CI: 3.15–5.16, P < 0.001). A subgroup analysis based on histological type indicated an elevated risk for both squamous cell carcinoma (OR = 2.21, 95% CI: 2.00–2.45, P < 0.001), and adenocarcinoma (OR = 1.61, 95% CI: 1.21–2.15, P = 0.001), in associated with C. trachomatis. Subgroup analysis by where C. trachomatis infection was detected showed a significantly higher risk of cervical cancer associated with C. trachomatis infection detected in serum (OR = 2.20, 95% CI: 2.01–2.42, P < 0.001), cervical tissue blocks (OR = 2.88, 95% CI: 1.21–6.83, P = 0

    Diabetes may affect the typical physical findings associated with cervical spondylotic myelopathy, as coexisting diabetic neuropathy may dampen expected hyperreflexia and also produce non-dermatomal extremity numbness. Most large studies of surgically treated diabetic patients with cervical spondylotic myelopathy have focused upon infection rates rather than exploring any differences in the presenting physical signs. We conducted a retrospective study of the pattern of presenting neurological signs and symptoms and of the clinical outcomes in 438 patients surgically treated for cervical spondylotic myelopathy, 79 of whom had diabetes. Compared with non-diabetic patients, those with diabetes were slightly older and had lower preoperative modified Japanese Orthopaedic Association (mJOA) scores. Those with diabetes also had a significantly higher incidence of hyporeflexia and a higher incidence of a positive Babinski sign, but there was no difference in the appearance of the Hoffman sign. The magnitude of mJOA improvement after surgery was comparable. We conclude that diabetes may alter the typical signs and symptoms of cervical spondylotic myelopathy and suggest that knowledge of the differences may aid in securing a prompt and accurate diagnosis.

    Cervical pregnancy is a rare type of ectopic pregnancy and it represents <1% of all ectopic pregnancies. Early diagnosis and medical management with systemic or local administration of methotrexate is the treatment of choice. If the pregnancy is disturbed, it may lead to massive hemorrhage, which may require hysterectomy to save the patient. We report three cases of cervical pregnancy managed successfully with different approaches of management. Our first case, 28 years old G3P2L2 with previous two lower segment cesarean sections, presented with bleeding per vaginum following 6 weeks of amenorrhea. Clinical examination followed by transvaginal ultrasound confirmed the diagnosis of cervical pregnancy. Total abdominal hysterectomy was done in view of intractable bleeding to save the patient. The second case, a 26-year-old second gravida with previous normal vaginal delivery presented with pain abdomen and single episode of spotting per vaginum following 7 weeks of amenorrhea. Transvaginal ultrasound revealed empty endometrial cavity, closed internal os with gestational sac containing live fetus of 7 weeks gestational age in cervical canal and she was treated with intra-amniotic potassium chloride followed by systemic methotrexate. Follow up with serum beta human chorionic gonadotropin level revealed successful outcome. Our third case, a 27-year-old primigravida with history of infertility treatment admitted with complaints of bleeding per vaginum for 1 day following 8 weeks amenorrhea. She was diagnosed as cervical pregnancy by clinical examination, confirmed by transvaginal ultrasonography and subsequently managed by dilation and curettage with intracervical Foleys' ballon tamponade.

    A cell strain (FU-GBC-1) was established from cancerous ascites of a 68-year-old male patient with well-differentiated adenocarcinoma of the gallbladder. By light and electron microscopy, the cultured cells showed the morphologic features of adenocarcinoma characterized by gland-like structures, intracellular microcystic spaces, and mucous production. Immunoperoxidase stains showed that FU-GBC-1 cells expressed several epithelial tumor antigens including CA 19-9, carcinoembryonic antigen (CEA), and epithelial membrane antigen (EMA). The cell strain has been in continuous culture up to passage 44 for 1 1/2 years, with the population doubling time of 120 hours. The cytogenetic analysis by a G-band technique showed a constant loss of chromosome Y in FU-GBC-1 cells. The modal chromosome number at passage 12 was 82 with a range of 77 to 85. Flow cytometry with an ethidium bromide technique additionally confirmed aneuploid DNA content (4C) in the cultured cells at passage 12 and 35. Inoculation of FU-GBC-1 cells into the dermis of BALB/c nude mice produced transplantable adenocarcinoma identical to the original tumor. Because no continuous cell lines of the well-differentiated type of gallbladder adenocarcinoma have been reported in the literature currently, the newly established cell strain we report may yield a useful system for studying the morphologic and biologic characteristics of gallbladder adenocarcinoma.

    The relation between various risk factors and adenocarcinoma of the lung was evaluated in a case-control study. Subjects were selected from the Colorado Central Cancer Registry from 1979-1982 in the Denver metropolitan area. A total of 102 (50 males and 52 females) adenocarcinoma case interviews and 131 (65 males and 66 females) control interviews were completed. The control group consisted of persons with cancers of the colon and bone marrow. The risk estimates associated with cigarette smoking were significantly elevated among males (odds ratio (OR) = 4.49) and females (OR = 3.95) and were found to increase significantly (p less than 0.01) with increasing levels of cigarette smoking for both males and females. For adenocarcinoma in females, the age- and smoking-adjusted odds ratios at different levels of passive smoke exposure followed an increasing overall trend (p = 0.05). After additional adjustment for potential confounders, prior cigarette use remained the most significant predictor of risk of adenocarcinoma among males and females. Analysis restricted to nonsmoking females revealed a risk of adenocarcinoma of 1.68 (95% confidence interval (Cl) = 0.39-2.97) for passive smoke exposure of four or more hours per day. Neither sex showed significantly elevated risk for occupational exposures, although males bordered on significance (OR = 2.23, 95% Cl = 0.97-5.12). The results suggest the need to develop cell type-specific etiologic hypotheses.

    Heat shock protein 70 (hsp70), is a molecular chaperone that binds to c-myc and regulates its accumulation and localisation. In an attempt to confirm this association and to find out its prognostic significance in cervical carcinoma, paraffin embedded sections from 15 chronic cervicitis, 31 squamous cell carcinomas (scc) and 7 adenocarcinomas of the uterine cervix were immunohistochemically (IHC) stained for hsp70 and c-myc. hsp70 was faintly expressed cytoplasmically in non neoplastic squamous and endocervical epithelium, while mainly nuclear staining with variable intensities was seen in all scc and in squamous intraepithelial lesions (SIL) overlying 8 tumors. Both cytoplasmic and nuclear staining was noted in adenocarcinoma. c-myc was moderately expressed in the cytoplasm of all non neoplastic endocervical glands, while very mild cytoplasmic staining was noted in squamous epithelium. In SIL and in scc the staining intensity increased and was mainly nuclear. For adenocarcinoma, nuclear and cytoplasmic staining with different intensities was noted. There were significant positive correlations between the IHC expression of hsp70 and c-myc (p = 0.0001). In conclusion, our results confirm the co-association of c-myc and hsp70. This co-association might be a mechanism of tumor escape by preventing hsp70 binding to one of its normal target, the MHC class I, and preventing its subsequent expression on the surface of the cancerous cells. Lastly, the nuclear expression of hsp70 might be considered as an indicator of malignant transformation. PMID:9673366

The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    The cervical disc herniation is characterized by prolapsed nucleus pulposus material through the annulus into the spinal canal. The local mechanical or chemical irritation of neural structures typically leads to symptoms of radiculopathy, cervicocephalgia or myelopathy. Pronounced sensorimotor deficits or intractable pain constitute surgical treatment. In all other cases conservative treatment is indicated, including pain medication, active and passive physiotherapy, and local injections, respectively. Anterior cervical discectomy and interbody fusion (ACDF) is still the surgical treatment of choice. Predominantly, cages with or without plates are in use to obtain solid fusion. The implantation of a total disc replacement is a viable alternative, if no contraindications exist. Other surgical techniques may be performed in proper selected cases. The overall clinical and radiological results of both surgical and conservative treatment are good. PMID:23296562

    Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.

    Thiery, M

    1983-01-01

    This work reviews the evolution of cervical ripening procedures and discusses the most effective current techniques. Current knowledge of the process of spontaneous ripening of the cervix is briefly assessed, but the review concentrates on methodological aspects and the clinical results of preinduction cervical ripening. The historical development of mechanical and pharmacologic ripening procedures is examined, including enzymes, oxytocin, relaxin, corticosteriods, estrogens administered parenterally or locally, and prostaglandins (PGs) administered intravenously, orally, locally, and intravaginally. 3 effective procedures for preinduction cervical ripening are identified and described in greater detail: the catheter technique and local and vaginal administration of PGs. The extraamniotic catheter technique is simple, effective, and safe and is recommended for patients with not totally unripe cervixes and for whom PGs are unavailable or contraindicated. Single-dose extraamniotic instillation of PGE2 in Tylose gel was found to be highly effective for priming the unfavorable cervix before conventional labor induction. In some patients the procedure induces labor. The technique is easy to use, well accepted by the woman, and safe when applied appropriately to carefully selected patients. PGF2alpha gel has been less thoroughly studied. Electronic monitoring at the ripening stage is recommended for patients at risk, and even in low-risk cases much larger series will require study before conclusions can be reached about safety. Injection of PG gel into the cervical canal is less invasive than extraamniotic instillation, but no definite conclusions about its safety are possible due to small series and dissimilar clinical protocols. Pericervical administration of PGE2 and PGF2 alpha and intracervical and intraamniotic tablets of PGE2 are briefly assessed. Adoption of the intravaginal route has been a major step in the development of ripening techniques. 3 types of media

    Cervical spondylosis is caused by degenerative disc disease and usually produces intermittent neck pain in middle-aged and elderly patients. This pain usually responds to activity modification, neck immobilization, isometric exercises, and medication. Neurologic symptoms occur infrequently, usually in patients with congenital spinal stenosis. For these patients, magnetic resonance imaging is the preferred initial diagnostic study. Because involvement of neurologic structures on imaging studies may be asymptomatic, consultation with a neurologist is advised to rule out other neurologic diseases. In most cases of spondylotic radiculopathy, the results of conservative treatment are so favorable that surgical intervention is not considered unless pain persists or unless there is progressive neurologic deficit. If indicated, a surgical procedure may be done through the anterior or posterior cervical spine; results are gratifying, with long-term improvement in 70% to 80% of patients. Cervical spondylotic myelopathy is the most serious and disabling condition of this disease. Because many patients have nonprogressive minor impairment, neck immobilization is a reasonable treatment in patients presenting with minor neurologic findings or in whom an operation is contraindicated. This simple remedy will result in improvement in 30% to 50% of patients. Surgical intervention is indicated for patients presenting with severe or progressive neurologic deficits. Anterior cervical approaches are generally preferred, although there are still indications for laminectomy. Surgical results are modest, with good initial results expected in about 70% of patients. Functional outcome noticeably declines with long-term follow-up, which raises the question of whether, and how much, surgical treatment affects the natural course of the disease. Prospective randomized studies are needed to answer these questions. Images Figure 1. Figure 2. Figure 3. PMID:8855684

    The 2015 WHO classification of tumors of the lung, pleura, thymus and heart has just been published with numerous important changes from the 2004 WHO classification. The most significant changes involve (1) use of immunohistochemistry throughout the classification, (2) integration of molecular testing for personalized strategies for advanced lung cancer patients, (3) a new classification for small biopsies and cytology, (4) a new classification of lung adenocarcinoma as proposed by the 2011 IASLC/ATS/ERS, (5) restriction of the diagnosis of large cell carcinoma only to resected tumors that lack any clear morphologic or immunohistochemical differentiation. Regarding adenocarcinoma, the terms bronchioloalveolar carcinoma (BAC) and mixed subtype adenocarcinoma have been suppressed and replaced for the former by the term adenocarcinoma in situ (AIS) as a preinvasive lesion to join atypical adenomatous hyperplasia (AAH). A new category has been defined, the minimally invasive adenocarcinoma (MIA), and invasive adenocarcinomas are now classified according to the predominant subtype after subtyping by semi-quantitatively percentage of various subtypes present in 5% increments. The term "lepidic" is restricted to a non-invasive component (previously classified as BAC) present as part of an invasive adenocarcinoma. "Invasive mucinous adenocarcinoma" is used for formerly adenocarcinomas classified as mucinous BAC, excluding tumors that meet criteria for AIS or MIA. The subtypes of clear cell and signet ring adenocarcinoma are discontinued, as well the term of mucinous cystadenocarcinoma, included in the category of colloid adenocarcinoma. Thus new classification of lung adenocarcinoma is sustained by genetics and has clinical impact for therapeutic strategies. PMID:26791238

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    Rigid cervical deformities are difficult problems to treat. The goals of surgical treatment include deformity correction, achieving a rigid fusion, and performing a thorough neural decompression. In stiff and ankylosed cervical spines, osteotomies are required to restore sagittal and coronal balance. In this chapter, we describe the clinical and radiographic workup for patients with cervical deformities, and delineate the various factors that must be considered when planning surgical treatment. We also describe in detail the various types of cervical osteotomies, along with their surgical technique, advantages, and potential complications. PMID:26949476

    The cervical cap is now available for general use by American women. Several steps are necessary to select women who are good candidates for cap usage and to successfully fit the cap. Many women are not good candidates for the cap. The cap is generally not suitable for women who have recently become sexually active or who are first-time contraceptors. Many users are women who cannot use more widely available contraceptives. Successful cap use requires a highly motivated, persistent woman who will correctly insert and remove her cap. The size, shape, length, position and location of the cervix must be assessed by the clinician prior to fitting the cap. The cervix should be visually inspected for lesions or cervicitis and a Pap smear should be taken. After an initial cap is selected, the stability of the cap, gaps between the cap and cervix, areas of uncovered cervix and the adequacy of the suction seal should be assessed. The woman should be taught how to insert and remove the cap. Additionally, she should be instructed to use a backup method of contraception until she is sure that the cap will remain in place during sexual intercourse. Successful cap fitting requires a careful, methodical approach by the clinician and a carefully selected, highly motivated client. This article presents the steps of cervical cap fitting.

    2011-01-01

    Background Cervical cancer continues to be an important worldwide health problem for women. Up to 35% of patients who are diagnosed with and appropriately treated for cervical cancer will recur and treatment results are poor for recurrent disease. Given these sobering statistics, development of novel therapies for cervical cancer remains a high priority. We evaluated the expression of Tissue Factor (TF) in cervical cancer and the potential of hI-con1, an antibody-like-molecule targeted against TF, as a novel form of immunotherapy against multiple primary cervical carcinoma cell lines with squamous- and adenocarcinoma histology. Methods Because TF is a transmembrane receptor for coagulation factor VII/VIIa (fVII), in this study we evaluated the in vitro expression of TF in cervical carcinoma cell lines by immunohistochemistry (IHC), real time-PCR (qRT-PCR) and flow cytometry. Sensitivity to hI-con1-dependent cell-mediated-cytotoxicity (IDCC) was evaluated in 5-hrs-51chromium-release-assays against cervical cancer cell lines in vitro. Results Cytoplasmic and/or membrane TF expression was observed in 8 out of 8 (100%) of the tumor tissues tested by IHC and in 100% (11 out of 11) of the cervical carcinoma cell lines tested by real-time-PCR and flow cytometry but not in normal cervical keratinocytes (p = 0.0023 qRT-PCR; p = 0.0042 flow cytometry). All primary cervical cancer cell lines tested overexpressing TF, regardless of their histology, were highly sensitive to IDCC (mean killing ± SD, 56.2% ± 15.9%, range, 32.4%-76.9%, p < 0.001), while negligible cytotoxicity was seen in the absence of hI-con1 or in the presence of rituximab-control-antibody. Low doses of interleukin-2 further increased the cytotoxic effect induced by hI-con1 (p = 0.025) while human serum did not significantly decrease IDCC against cervical cancer cell lines (p = 0.597). Conclusions TF is highly expressed in squamous and adenocarcinoma of the uterine cervix. hI-con1 induces strong cytotoxicity

    Purpose To describe an approach to cervical brachytherapy in a patient with congenital septate uterus and locally advanced cervical carcinoma. Material and methods The patient is a 34-year-old female with septate uterus presenting with pelvic pain. Workup demonstrated a stage IIB cervical adenocarcinoma with imaging evidence of an involved right external iliac lymph node. The patient received whole pelvic radiation, with concurrent weekly cisplatin (40 mg/m2), to a dose of 45 Gy in 25 fractions followed by a parametrial boost of 5.4 Gy and an additional nodal boost of 9 Gy. Results The patient was initiated on cervical brachytherapy following fraction 23 of pelvic radiation. To conform to her septated uterus, a Rotte-Y tandem was used. Additionally, 2 CT-compatible ovoids were placed in the vaginal apex to enhance dose distribution and coverage of the target volume. Each fraction of brachytherapy was performed with CT-based planning. A high-risk clinical target volume (HR-CTV) and normal structures were defined and constrained per American Brachytherapy Society (ABS) and Groupe Européen de Curiethérapie/European Society for Therapeutic Radiology and Oncology (GEC-ESTRO) guidelines. The brachytherapy dose was 27.5 Gy in 5 fractions of 5.5 Gy each, prescribed to the HR-CTV. Conclusions Herein, we report the first documented case of cervical brachytherapy in a patient with septate uterus and locally advanced cervical carcinoma. Using CT-guided planning, in conjunction with the ABS and GEC-ESTRO guidelines, the patient was effectively treated with adapted cervical brachytherapy, meeting criteria for HR-CTV coverage and normal tissue tolerances.

    The present study screened potential genes related to lung adenocarcinoma, with the aim of further understanding disease pathogenesis. The GSE2514 dataset including 20 lung adenocarcinoma and 19 adjacent normal tissue samples from 10 patients with lung adenocarcinoma aged 45-73 years was downloaded from Gene Expression Omnibus. Differentially expressed genes (DEGs) between the two groups were screened using the t-test. Potential gene functions were predicted using functional and pathway enrichment analysis, and protein-protein interaction (PPI) networks obtained from the STRING database were constructed with Cytoscape. Module analysis of PPI networks was performed through MCODE in Cytoscape. In total, 535 upregulated and 465 downregulated DEGs were identified. These included ATP5D, UQCRC2, UQCR11 and genes encoding nicotinamide adenine dinucleotide (NADH), which are mainly associated with mitochondrial ATP synthesis coupled electron transport, and which were enriched in the oxidative phosphorylation pathway. Other DEGs were associated with DNA replication (PRIM1, MCM3, and RNASEH2A), cell surface receptor-linked signal transduction and the enzyme-linked receptor protein signaling pathway (MAPK1, STAT3, RAF1, and JAK1), and regulation of the cytoskeleton and phosphatidylinositol signaling system (PIP5K1B, PIP5K1C, and PIP4K2B). Our findings suggest that DEGs encoding subunits of NADH, PRIM1, MCM3, MAPK1, STAT3, RAF1, and JAK1 might be associated with the development of lung adenocarcinoma. PMID:26840709

    OBJECTIVE: This single-institution experience retrospectively reviews the outcomes in a group of patients treated 5 or more years ago by pancreaticoduodenectomy for periampullary adenocarcinoma. SUMMARY BACKGROUND DATA: Controversy exists regarding the benefit of resection for periampullary adenocarcinoma, particularly for pancreatic tumors. Many series report only Kaplan-Meier actuarial 5-year survival rates. There are believed to be discrepancies between the actuarial 5-year survival data and the actual 5-year survival rates. METHODS: From April 1970 through May 1992, 242 patients underwent pancreaticoduodenal resection for periampullary adenocarcinoma at The Johns Hopkins Hospital. Follow-up was complete through May 1997. All pathology specimens were reviewed and categorized. Actual 5-year survival rates were calculated. The demographic, intraoperative, pathologic, and postoperative features of patients surviving > or =5 years were compared with those of patients who survived <5 years. RESULTS: Of the 242 patients with resected periampullary adenocarcinoma, 149 (62%) were pancreatic primaries, 46 (19%) arose in the ampulla, 30 (12%) were distal bile duct cancers, and 17 (7%) were duodenal cancers. There was a 5.3% operative mortality rate during the 22 years of the review, with a 2% operative mortality rate in the last 100 patients. There were 58 5-year survivors, 28 7-year survivors, and 7 10-year survivors. The tumor-specific 5-year actual survival rates were pancreatic 15%, ampullary 39%, distal bile duct 27%, and duodenal 59%. When compared with patients who did not survive 5 years, the 5-year survivors had a significantly higher percentage of well-differentiated tumors (14% vs. 4%; p = 0.02) and higher incidences of negative resection margins (98% vs. 73%, p < 0.0001) and negative nodal status (62% vs. 31%, p < 0.0001). The tumor-specific 10-year actuarial survival rates were pancreatic 5%, ampullary 25%, distal bile duct 21%, and duodenal 59%. CONCLUSIONS

    Background: The sensitivity of cervical cytology for detection of glandular lesions is reported to be low. We conducted this study to assess the diagnostic accuracy of cervical Papanicolaou (Pap) smears for uterine glandular lesions and to compare the diagnostic utility of conventional and liquid-based cytology (LBC) smears for glandular lesions. Materials and Methods: Archived histopathology records of all cases reported as endocervical and endometrial adenocarcinoma in the study period were identified and the available corresponding Pap smears (in preceding 1 year) were retrieved. In addition, the Pap smears reported as glandular cell abnormalities (GCA) during the same study period were retrieved. The overall prevalence of GCA, sensitivity, and specificity of Pap smears for the detection of GCA was calculated. The diagnostic accuracy of conventional and LBC smears for the diagnosis of GCA was also compared. Results: The prevalence of GCA in our study was 0.32%. The overall specificity of Pap smears for the diagnosis of GCA was 60.8%, this was not significantly different between conventional and LBC smears (P = 0.4). The overall sensitivity of Pap smears for the detection of GCA was 41.8%; LBC smears had significantly better sensitivity as compared to conventional smears for the detection of endometrial as compared to endocervical adenocarcinoma (P < 0.05). Conclusions: The prevalence of GCA in Pap smears is low. The specificity of Pap smears, for diagnosis of GCA, was found to be moderate. However, the overall sensitivity of Pap smears for the detection of GCA was low, though better for LBC as compared to conventional smears. PMID:27014363

    Adenoma malignum is a highly differentiated mucinous adenocarcinoma of the cervix with a deceptively innocent histologic appearance but a highly aggressive behavior. We describe a patient who had adenoma malignum associated with Peutz-Jeghers syndrome (PJS) and bilateral ovarian sex cord tumor with annular tubules (SCTAT). The relatively frequent occurrence of cervical adenoma malignum in women with PJS warrants close surveillance by gynecologists for early detection and treatment of this cancer. We report the 16th known case of PJS with adenoma malignum and only the 8th known case of PJS with adenoma malignum and bilateral SCTAT. The highly aggressive nature of cervical adenoma malignum is exemplified, and the difficulties associated with early diagnosis are discussed. The clinical significance of cervical and ovarian tumors associated with PJS is reviewed. PMID:8188091

    A significant role of high-risk Human papilloma viruses (HR HPV) in the development of cervical carcinoma is well known. HR HPV 16 and 18 account for approximately 70% of all cases of cervical cancer worldwide. The incidence of cervical cancer in Serbia, is one of the highest in Europe. The aim of our study was to investigate the distribution of HR HPV types in cervical carcinoma of Serbian women, as well as association between the HPV types and pathohistological findings. The study included 80 archival cervical cancer tissues from the same number of patients. The presence of HPV DNA was determined using MY09/MY11 primers for L1 gene and GP1/GP2 primers for E1 gene. HPV was detected in 78.75% tissues. HR HPV genotypes found in the decreasing order of frequency were: HPV16 (80.39%), HPV33 (7.84%), HPV58 (5.88%), HPV18 (1.96%), HPV45 (1.96%) and HPV53 (1.96%). The examined tissues were 91.25% squamous cell carcinomas and 8.75% adenocarcinoma. The high frequency of HPV 16 was observed in both types of carcinoma (80.8% and 75%, respectively) while the prevalence of HPV18 was low. These results may contribute to the implementation of cervical carcinoma prevention program in Serbia, including the selection of the most appropriate vaccine and immunization program. PMID:27461126

    OBJECTIVES: The aim of this study was to review the literature on cervical spine fractures. METHODS: The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS: Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients complaining of neck pain. These fractures are more common in men approximately 30 years of age and are most often caused by automobile accidents. The cervical spine is divided into the upper cervical spine (occiput-C2) and the lower cervical spine (C3-C7), according to anatomical differences. Fractures in the upper cervical spine include fractures of the occipital condyle and the atlas, atlanto-axial dislocations, fractures of the odontoid process, and hangman's fractures in the C2 segment. These fractures are characterized based on specific classifications. In the lower cervical spine, fractures follow the same pattern as in other segments of the spine; currently, the most widely used classification is the SLIC (Subaxial Injury Classification), which predicts the prognosis of an injury based on morphology, the integrity of the disc-ligamentous complex, and the patient's neurological status. It is important to correctly classify the fracture to ensure appropriate treatment. Nerve or spinal cord injuries, pseudarthrosis or malunion, and postoperative infection are the main complications of cervical spine fractures. CONCLUSIONS: Fractures of the cervical spine are potentially serious and devastating if not properly treated. Achieving the correct diagnosis and classification of a lesion is the first step toward identifying the most appropriate treatment, which can be either surgical or conservative. PMID:24270959

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Chylous ascites is an uncommon postoperative complication of gynecological surgery. We report a case of chylous ascites following a robotic lymph node dissection for a cervical carcinoma. A 38-year-old woman with IB2 cervical adenocarcinoma with a palpable 3 cm left external iliac lymph node was taken to the operating room for robotic-assisted laparoscopic pelvic and para-aortic lymph node dissection. Patient was discharged on postoperative day 2 after an apparent uncomplicated procedure. The patient was readmitted the hospital on postoperative day 9 with abdominal distention and a CT-scan revealed free fluid in the abdomen and pelvis. A paracentesis demonstrated milky-fluid with an elevated concentration of triglycerides, confirming the diagnosis of chylous ascites. She recovered well with conservative measures. The risk of postoperative chylous ascites following lymph node dissection is still present despite the utilization of new technologies such as the da Vinci robot. PMID:21607099

    Adenocarcinoma is a type of cancer that occurs in the glandular cells throughout the body. There are several metastatic adenocarcinoma of unknown primary origin. Currently, there is no highly effective method to differentiate pancreatic ductal adenocarcinoma (PDAC) from other adenocarcinomas. Here, we identified pancreas tissue by site-specific methylation at FRY and found that it can also detect PDAC. The establishment of Combined Bisulphite Restriction Analysis (COBRA) and quantitative real-time PCR techniques of FRY revealed FRY hypermethylation in 21 out of 24 normal pancreatic tissue samples, whereas all other normal tissue samples from thirteen other organs (80 samples) remained totally unmethylated. Similarly in application to PDAC, this marker effectively indicated 25 PDAC among 151 other common adenocarcinomas with values of 100%, 98.7%, 92.6%, and 100% in sensitivity, specificity, positive predictive value and negative predictive value, respectively. In summary, we have demonstrated that this epigenetic site-specific marker has high potential for pancreatic tissue identification and can be applied in PDAC diagnosis. PMID:26990916

  20. Changing rates of adenocarcinoma of the lung.

    Over the past several decades, adenocarcinoma of the lung has been increasing as a fraction of all lung cancer. Examination of the available evidence led the 2014 Report of the Surgeon General to conclude that the increases in the rates of adenocarcinoma among smokers in the U.S. were a result of changes in cigarette design and composition over the past 6 decades. While a causal link to design and composition changes as a whole is clear, the changes that have been implemented over the past several decades are not uniformly applied across all cigarette brands in the current market, raising questions about differences in risks among users of different cigarette brands. Recognition of the increased risks resulting from design and composition changes offers a corollary opportunity to reduce current disease risks by identifying and regulating the specific compositional and design changes that produced the increase in risk.

    Choroidal or cutaneous metastasis of gastric cancer is rare. Gastrointestinal cancer was found in only 4% in patients with uveal metastasis. Choroidal metastasis from gastric cancer was reported in two cases in earlier literature. The frequency of gastric cancer as a primary lesion was 6% in cutaneous metastasis of men, and cutaneous metastasis occurs in 0.8% of all gastric cancers. We report a patient with gastric adenocarcinoma who presented with visual disorder in his left eye and skin pain on his head as his initial symptoms. These symptoms were diagnosed to be caused by choroidal and cutaneous metastasis of gastric adenocarcinoma. Two cycles of chemotherapy consisted of oral S-1 and intravenous cisplatin (SPIRITS regimen); this was markedly effective to reduce the primary gastric lesion and almost all the metastatic lesions.

    Primary adenocarcinomas of the presacral (retrorectal) space are rare. The diagnosis is usually delayed because of non-specific symptoms, and is made after a biopsy or surgery. These carcinomas arise from cystic lesions developing from remnants of the embryological postanal gut containing mucous-secreting epithelium, known as tail gut cysts. The potential for infection, perianal fistulas and most importantly, malignant change warrants an early complete surgical resection. From an oncologist’s perspective, the management of these carcinomas has varied, and has included adjuvant chemotherapy and/or radiation therapy. We describe here a rare case of adenocarcinoma associated with a tail gut cyst that was discovered incidentally and resected by a posterior approach (Kraske procedure). The patient has had clinical and periodic radiologic surveillance without any evidence of cancer recurrence for over a year and a half. PMID:23450681

    The circadian clock controls metabolic and physiological processes through finely tuned molecular mechanisms. The clock is remarkably plastic and adapts to exogenous "zeitgebers," such as light and nutrition. How a pathological condition in a given tissue influences systemic circadian homeostasis in other tissues remains an unanswered question of conceptual and biomedical importance. Here, we show that lung adenocarcinoma operates as an endogenous reorganizer of circadian metabolism. High-throughput transcriptomics and metabolomics revealed unique signatures of transcripts and metabolites cycling exclusively in livers of tumor-bearing mice. Remarkably, lung cancer has no effect on the core clock but rather reprograms hepatic metabolism through altered pro-inflammatory response via the STAT3-Socs3 pathway. This results in disruption of AKT, AMPK, and SREBP signaling, leading to altered insulin, glucose, and lipid metabolism. Thus, lung adenocarcinoma functions as a potent endogenous circadian organizer (ECO), which rewires the pathophysiological dimension of a distal tissue such as the liver. PAPERCLIP. PMID:27153497

    Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively. The operative strategy had to be adjusted due to this unexpected finding. Although there are published cases of appendiceal adenocarcinoma inducing intussusception and thus mimicking a cecal polyp, there are no reports in the literature describing invasion of the appendix through the rectal wall and thus mimicking a rectal polyp. The patient is a 75-year-old female who presented with spontaneous hematochezia and, on colonoscopy, was noted to have a rectal polyp that appeared to be located within a diverticulum. When endoscopic mucosal resection was not successful, she was referred to colorectal surgery for a low anterior resection. Preoperative imaging was notable for an enlarged appendix adjacent to the rectum. Intraoperatively, the appendix was found to be densely adherent to the right lateral rectal wall. An en bloc resection of the distal sigmoid colon, proximal rectum and appendix was performed, with pathology demonstrating appendiceal adenocarcinoma that invaded through the rectal wall. The prognosis in this type of malignancy weighs heavily on whether or not perforation and spread throughout the peritoneal cavity have occurred. In this unusual presentation, an en bloc resection is required for a complete resection and to minimize the risk of peritoneal spread. Unusual appearing polyps do not always originate from the bowel wall. Abnormal radiographic findings adjacent to an area of gastrointestinal pathology may

    From January 1981 to December 1988, a prospective trial was conducted on 216 consecutive patients undergoing hysterectomy for FIGO stage I endometrial adenocarcinoma to determine the accuracy of intraoperative frozen section (IFS) diagnosis of depth of myometrial invasion. IFS and D&C diagnoses were compared to the permanent section diagnosis to determine their accuracy. Patients with an IFS or D&C diagnosis of grade 3 carcinoma, deep myometrial invasion, cervical invasion, or adnexal involvement were considered high risk for paraaortic nodal metastasis, and paraaortic lymphadenectomy was performed. IFS correctly diagnosed the depth of myometrial invasion in 194 of 204 cases (95%). The sensitivity of IFS diagnosis of deep invasion was 87%, the specificity was 99%, the positive predictive value was 98%, and the negative predictive value was 94%. Grade, subtype, cervical invasion, and adnexal involvement were also accurately diagnosed. Based on IFS and D&C diagnosis, paraaortic lymphadenectomy was performed in 32% of patients, while 68% were considered low risk and were spared paraaortic lymphadenectomy. Eight patients (5%) were incorrectly diagnosed as low risk and did not have paraaortic lymphadenectomy performed. Sixty-five of seventy-three (90%) patients considered high risk on permanent section had paraaortic lymphadenectomies performed on the basis of IFS and D&C diagnosis. Inaccurate IFS diagnosis of depth of myometrial invasion can occur when tumor involves the uterine isthmus or cornua and when tumor invades areas of adenomyosis. PMID:2323612

    Pancreatic adenocarcinoma displays a variety of molecular changes that evolve exponentially with time and lead cancer cells not only to survive, but also to invade the surrounding tissues and metastasise to distant sites. These changes include: genetic alterations in oncogenes and cancer suppressor genes; changes in the cell cycle and pathways leading to apoptosis; and also changes in epithelial to mesenchymal transition. The most common alterations involve the epidermal growth factor receptor (EGFR) gene, the HER2 gene, and the K-ras gene. In particular, the loss of function of tumor-suppressor genes has been documented in this tumor, especially in CDKN2a, p53, DPC4 and BRCA2 genes. However, other molecular events involved in pancreatic adenocarcinoma pathogenesis contribute to its development and maintenance, specifically epigenetic events. In fact, key tumor suppressors that are well established to play a role in pancreatic adenocarcinoma may be altered through hypermethylation, and oncogenes can be upregulated secondary to permissive histone modifications. Indeed, factors involved in tumor invasiveness can be aberrantly expressed through dysregulated microRNAs. This review summarizes current knowledge of pancreatic carcinogenesis from its initiation within a normal cell until the time that it has disseminated to distant organs. In this scenario, highlighting these molecular alterations could provide new clinical tools for early diagnosis and new effective therapies for this malignancy. PMID:24084722

    Adenocarcinoma of the lung is the leading cause of cancer death worldwide. Here we report molecular profiling of 230 resected lung adenocarcinomas using messenger RNA, microRNA and DNA sequencing integrated with copy number, methylation and proteomic analyses. High rates of somatic mutation were seen (mean 8.9 mutations per megabase). Eighteen genes were statistically significantly mutated, including RIT1 activating mutations and newly described loss-of-function MGA mutations which are mutually exclusive with focal MYC amplification. EGFR mutations were more frequent in female patients, whereas mutations in RBM10 were more common in males. Aberrations in NF1, MET, ERBB2 and RIT1 occurred in 13% of cases and were enriched in samples otherwise lacking an activated oncogene, suggesting a driver role for these events in certain tumours. DNA and mRNA sequence from the same tumour highlighted splicing alterations driven by somatic genomic changes, including exon 14 skipping in MET mRNA in 4% of cases. MAPK and PI(3)K pathway activity, when measured at the protein level, was explained by known mutations in only a fraction of cases, suggesting additional, unexplained mechanisms of pathway activation. These data establish a foundation for classification and further investigations of lung adenocarcinoma molecular pathogenesis. PMID:25079552

    Objectives To identify factors associated with disease-specific survival (DSS) in intestinal and nonintestinal sinonasal adenocarcinoma. Design Retrospective review. Setting Surveillance Epidemiology and End Results database. Participants Adult patients with sinonasal adenocarcinoma. Main Outcome Measures DSS. Results We identified 325 patients; of these, 300 had the nonintestinal type and 25 had intestinal type histologies. The 5-year DSS rates for patients who had no treatment, radiation (RT), surgery, and surgery and postoperative RT were 42.5, 46.1, 85.6, and 72.6%, respectively (log-rank test; p < 0.001). Black race, age ≥ 75 years, paranasal sinus involvement, and high grade were independently associated with decreased DSS. Compared with RT, surgery (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.15-0.77), and adjuvant RT (HR: 0.47; 95% CI, 0.26-0.86) were associated with improved DSS. Conclusions There is no difference in prognosis between intestinal and nonintestinal subtypes of sinonasal adenocarcinoma. Treatment with surgery alone or adjuvant RT is associated with a more favorable prognosis. PMID:26225303

    This case presentation examines a rare clinical entity: colorectal adenocarcinoma (CRC) metastasis to the tongue. CRC is among the least common tumors to metastasize to the oral cavity. Objectives for this case report are to (1) maintain a high index of suspicion for oral cavity tumors representing metastatic disease, (2) consider appropriate surgical and adjunctive interventions, and (3) recognize the significance of identifying the primary tumor via immunohistochemical staining. We present a case of a 57-year-old male with a history of stage IV rectal adenocarcinoma metastatic to the lung who presented to our clinic with a painful mass of the right lateral tongue that he noticed one month before. MRI of the neck revealed a mass involving the anterior two-thirds of the right tongue with irregular margins and an ipsilateral enlarged right jugulodigastric lymph node. The patient underwent right partial glossectomy with primary reconstruction and right modified radical neck dissection. Pathology confirmed poorly differentiated adenocarcinoma consistent with a colorectal primary with lymphovascular and perineural invasion. The tumor was staged as T2N1, and the patient was referred for chemoradiation. In this report, we discuss the presentation, diagnosis, and treatment of this uncommon disease, with a thorough review of the world literature. PMID:26759728

    Esophageal adenocarcinoma (EAC) is one of the fastest growing malignancies in the US and needs newer therapeutic and diagnostic strategies. Chronic inflammation plays a role in the pathogenesis of EAC and contributes to the dysplastic conversion of normal esophageal epithelium to Barrett's esophagus and frank adenocarcinoma. Chemokines play important roles in mediating inflammation and recent evidence implicates these ligands and their receptors in the development and spread of various tumors. We demonstrated that the chemokines IL8, CXCL1 and CXCL3 are significantly overexpressed during esophageal carcinogenesis and accompanied by amplification and demethylation of the chr4q21 gene locus. We also demonstrated that IL8 levels can be detected in serum of patients with EAC and can serve as potential biomarkers. We now demonstrate that inhibition of IL8 receptor, CXCR2, leads to decreased invasiveness of esophageal adenocarcinoma derived cells without affecting cellular proliferation. Taken together, these studies reveal the important roles that chemokines play in development of esophageal cancer and demonstrate that these pathways can serve as potential therapeutic targets.

    Background Development of tailored treatment based on immunohistochemical profiles (IPs) of tumors for cancers of unknown primary is needed. Methodology/Principal Findings We developed an algorithm based on primary known adenocarcinoma for testing sensitivity and specificity. Formalin-fixed paraffin-embedded tissue samples from 71 patients of unfavorable subsets of unknown primary adenocarcinoma were obtained. We examined 15 molecular markers using the algorithm incorporating these IPs and classified the tumours into 9 subsets based on the primary tumour site. The sensitivity and specificity of this algorithm were 80.3% and 97.6%, respectively. Apparent primary sites were lung in 17 patients, digestive organs in 13, gynecological organs in 9, prostate in 7, liver or kidney in 6, breast in 4, urothelial organ in 2, biliary tract and pancreatic profile in none, and unclassified in 13. The response rate to chemotherapy was highest for the gynecological IPs. Patients with gynecological or lung cancer IPs had longer median progression-free survival than those with others: 11.2 months for gynecological IPs (p<0.001) and 6.8 months for lung IPs (p = 0.05). Lung, digestive, prostate, and gynecological profiles were associated with significantly longer median survival time than the other profiles. Multivariate analysis confirmed that the IPs were independent prognostic factors for survival. Conclusions/Significance The IPs identified in this study can be used to further stratify patient prognosis for unfavorable subsets of unknown primary adenocarcinoma. PMID:22299055

    Endometrial adenocarcinoma is a common malignancy in women worldwide, with formation of remote metastasis occurring following oncological treatment. Circulating tumor cells (CTCs) are regarded to be the origin of haematogenous metastasis formation. The present study aimed to identify suitable marker genes using a quantitative polymerase chain reaction (qPCR) approach to detect CTCs from blood samples of patients with endometrial carcinoma. Therefore, RNA was isolated from endometrial adenocarcinoma cell lines and from healthy endometrial tissue and reverse transcribed to cDNA, which was then used in qPCR on a number of marker genes. Cytokeratin 19 and claudin 4 were identified as suitable marker genes for CTCs in endometrial adenocarcinoma, due to their high expression in the majority of the cell lines investigated. The expression values of the genes examined varied widely between the different cell lines, which is similar to the variation in the patient samples. Therefore, the necessity for a set of genes for CTC detection and not one single marker gene is demonstrated. qPCR is a fast, cost‑efficient and easy to perform technique, which may be used in the detection of CTCs. Investigation of the occurrence of CTCs in cancer patients would aid in the prevention of metastasis and thereby refine treatment. PMID:27431566

    Ductal pancreatic adenocarcinoma is by far the most common solid tumor of the pancreas. It has a very poor prognosis, especially in the more advanced stages which are no longer locally confined. Due to mostly unspecific symptoms, imaging is key in the diagnostic process. Because of the widespread use of imaging techniques, incidental findings are to a greater extent discovered in the pancreas, which subsequently entail further work-up. Ductal pancreatic adenocarcinoma can be mimicked by a large number of different lesions, such as anatomical variants, peripancreatic structures and tumors, rarer primary solid pancreatic tumors, cystic tumors, metastases or different variants of pancreatitis. Additionally, a number of precursor lesions can be differentiated. The correct classification is thus important as an early diagnosis of ductal pancreatic adenocarcinoma is relevant for the prognosis and because the possibly avoidable treatment is very invasive. All major imaging techniques are principally suitable for pancreatic imaging. In addition to sonography of the abdomen, usually the baseline diagnostic tool, computed tomography (CT) with its superior spatial resolution, magnetic resonance imaging (MRI) with its good soft tissue differentiation capabilities, possibly in combination with MR cholangiopancreatography (MRCP), endosonography with its extraordinary spatial resolution, conceivably with additional endoscopic retrograde CP or the option of direct biopsy and finally positron emission tomography CT (PET-CT) as a molecular imaging tool are all particularly useful modalities. The various techniques all have its advantages and disadvantages; depending on the individual situation they may need to be combined. PMID:27000276

    Background Sinonasal adenocarcinomas are uncommon tumors which develop in the ethmoid sinus after exposure to wood dust. Although the etiology of these tumors is well defined, very little is known about their molecular basis and no diagnostic tool exists for their early detection in high-risk workers. Methods To identify genes involved in this disease, we performed gene expression profiling using cancer-dedicated microarrays, on nine matched samples of sinonasal adenocarcinomas and non-tumor sinusal tissue. Microarray results were validated by quantitative RT-PCR and immunohistochemistry on two additional sets of tumors. Results Among the genes with significant differential expression we selected LGALS4, ACS5, CLU, SRI and CCT5 for further exploration. The overexpression of LGALS4, ACS5, SRI, CCT5 and the downregulation of CLU were confirmed by quantitative RT-PCR. Immunohistochemistry was performed for LGALS4 (Galectin 4), ACS5 (Acyl-CoA synthetase) and CLU (Clusterin) proteins: LGALS4 was highly up-regulated, particularly in the most differentiated tumors, while CLU was lost in all tumors. The expression of ACS5, was more heterogeneous and no correlation was observed with the tumor type. Conclusion Within our microarray study in sinonasal adenocarcinoma we identified two proteins, LGALS4 and CLU, that were significantly differentially expressed in tumors compared to normal tissue. A further evaluation on a new set of tissues, including precancerous stages and low grade tumors, is necessary to evaluate the possibility of using them as diagnostic markers. PMID:19903339

    Coexistence of microinvasive squamous cell carcinoma (MISCC) and microinvasive adenocarcinoma (MIAC) of the cervix is a rare phenomenon with very few clinically significant cases described in the literature. While a conservative approach has been studied, and may be effective in MISCC, a lower number of studies that recommend conservative treatment are available for MIAC. We report two cases of synchronous cervix lesions in two separate foci, MISCC and MIAC, who underwent fertility-sparing treatment with long-term follow-up. We describe clinical, histological, and immunohistochemical features of the two cases. The first case is a 41-year-old female with a diagnosis of MIAC of endocervical type, grade 1 differentiation, with a stromal invasion, associated with a separate area of squamous cell carcinoma (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1). The second case is a 45-year-old female with a diagnosis of plurifocal MISCC, associated with an MIAC of endocervical type with a stromal invasion (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1). After multidisciplinary counseling, both patients accepted conization as definitive treatment. Eleven years after the conization, all tests (Papanicolaou smear, colposcopy, cervical curettage, and hybrid capture 2-human papillomavirus test) planned quarterly in the first year and every 6 months in the subsequent years were negative in both patients. In women affected by stage IA1 squamous cervical cancer coexisting with stage IA1 adenocarcinoma endocervical type, with clear margins, and without lymphovascular space invasion, cervical conization may be considered a fertility-preserving, safe, and definitive therapeutic option.

We have encountered with the first case report of solitary psoas muscle metastasis of GEJ adenocarcinoma. Here we describe a 65 years old man was diagnosed with GEJ adenocarcinoma in Gastroenterology Department, Imam Hussein Hospital, Tehran, Iran in February 2014. We were not able to use PET techniques due to lack of access. Staging CT scans demonstrated a small mass lateral to right psoas muscle. A CT-guided core needle biopsy of right psoas muscle was performed that supported a diagnosis of adenocarcinoma consistent with primary adenocarcinoma of the GEJ. Distant metastasis to skeletal muscle rarely occurs in patients with GEJ adenocarcinoma, but heightened awareness to these soft tissue lesions is warranted. CT or MR imaging could show findings suggestive of metastatic disease, although PET is preferable modality. PMID:26870148

    Urothelial cancer is the most frequently diagnosed type of malignant tumor in the bladder, of which primary adenocarcinoma accounts for a small percentage. Secondary malignancies, in particular metastatic adenocarcinoma from the lung, are exceedingly rare, with only six cases previously reported in the literature. The present study describes the case of a 71-year-old Chinese male patient with known lung cancer for >2 years, who was diagnosed with metastatic adenocarcinoma to the bladder. The histopathological characteristics and immunohistochemical features of the patient are reported. It was proposed that pathologists should consider the possibility of metastatic adenocarcinoma from the lung, rather than assume a diagnosis of primary adenocarcinoma of the bladder or direct invasion of adenocarcinoma from the surrounding organs. Furthermore, it is essential to determine the medical history of each patient and observe the immunohistochemical features of all tumors prior to diagnosis. PMID:26622730

    Breast cancer 1, early onset (BRCA1)-interacting protein 1 (BRIP1), a DNA-dependent adenosine triphosphatase and DNA helicase, is required for BRCA-associated DNA damage repair functions, and may be associated with the tumorigenesis and aggressiveness of various cancers. The present study investigated the expression of BRIP1 in normal cervix tissues and cervical carcinoma via reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry assays. BRIP1 expression was observed to be reduced in squamous cancer tissue and adenocarcinoma compared with normal cervix tissue, and there were significant correlations between the reduction in BRIP1 expression and unfavorable variables, including the International Federation of Gynecologists and Obstetricians stage and presence of lymph node metastases. In order to elucidate the role of BRIP1 in cervical cancer, a BRIP1 recombinant plasmid was constructed and overexpressed in a cervical cancer cell line (HeLa). The ectopic expression of BRIP1 markedly inhibited the tumorigenic properties of HeLa cells in vitro, as demonstrated by decreased cell growth, invasion and adhesion, and increased cell apoptosis. In addition, it was identified that the inhibitory tumorigenic properties of BRIP1 may be partly attributed to the attenuation of RhoA GTPase activity. The present study provides a novel insight into the essential role of BRIP1 in cervical cancer, and suggests that BRIP1 may be a useful therapeutic target for the treatment of this common malignancy.

    Spontaneous preterm birth is a frequent complication of pregnancy and a common cause of morbidity in childhood. Obstetricians suspect abnormalities of the cervix are implicated in a significant number of preterm births. The cervix is composed of fibrous connective tissue and undergoes significant remodeling in preparation for birth. We hypothesized that a tissue engineering strategy could be used to develop three-dimensional cervical-like tissue constructs that would be suitable for investigating cervical remodeling. Cervical cells were isolated from two premenopausal women undergoing hysterectomy for a benign gynecological condition, and the cells were seeded on porous silk scaffolds in the presence or absence of dynamic culture and with 10% or 20% serum. Morphological, biochemical, and mechanical properties were measured during the 8-week culture period. Cervical cells proliferated in three-dimensions and synthesized an extracellular matrix with biochemical constituents and morphology similar to native tissue. Compared to static culture, dynamic culture was associated with significantly increased collagen deposition (p < 0.05), sulfated glycosaminoglycan synthesis (p < 0.05), and mechanical stiffness (p < 0.05). Serum concentration did not affect measured variables. Relevant human tissue-engineered cervical-like constructs constitute a novel model system for a range of fundamental and applied studies related to cervical remodeling. PMID:20121593

    Intramedullary ependymomas are surgically curable tumors. However, their surgical resection poses several challenges. In this intraoperative video we illustrate the main steps for the surgical resection of a cervical intramedullary ependymoma. These critical steps include: adequate exposure of the entire length of the tumor; use of the intraoperative ultrasound; identification of the posterior median sulcus and separation of the posterior columns; Identification of the plane between the spinal cord and the tumor; mobilization and debulking of the tumor and disconnection of the vascular supply (usually from small anterior spinal artery branches). Following these basic steps a complete resection can be safely achieved in many cases. The video can be found here: http://youtu.be/QMYXC_F4O4U. PMID:25175575

    Although Crohn's disease has been associated with an increased risk of small bowel adenocarcinoma, primary adenocarcinoma arising from an ileostomy is a complication that has been rarely documented in Crohn's disease. Chronic small bowel inflammation may lead to development of malignancy through the dysplasia-carcinoma sequence. We report a case of a 61-year-old woman with Crohn's ileocolitis diagnosed with a primary adenocarcinoma at the ileostomy with metastases to the liver 47 years after proctocolectomy, and review the literature.

    Cervical spine surgery is one of the most commonly performed spine surgeries in the United States, and 90% of the cases are related to degenerative cervical spine disease (the rest to cervical spine trauma and/or instability). The airway management for cervical spine surgery represents a crucial step in the anesthetic management to avoid injury to the cervical cord. The crux for upper airway management for cervical spine surgery is maintaining the neck in a neutral position with minimal neck movement during endotracheal intubation. Therefore, the conventional direct laryngoscopy (DL) can be unsuitable for securing the upper airway in cervical spine surgery, especially in cases of cervical spine instability and myelopathy. This review discusses the most recent evidence-based facts of the main advantages and limitations of different techniques available for upper airway management for cervical spine surgery.

Magnetic resonance imaging of the cervical spine showed a herniation of the nucleus pulposus and compressive myelopathy. The patient required surgical intervention and rehabilitation. Despite 6 mos of rehabilitation, residual hand dysfunction and minor ambulation problems persisted. Although massage has many benefits, this case reminds us that there is potential danger in performing neck massage. PMID:21862908

    We describe a case of a non-invasive precursor of minimal deviation adenocarcinoma (MDA) of the uterine cervix, associated with Peutz-Jeghers syndrome (PJS). A 27-year-old woman, who had been followed for PJS, was referred to the gynecology clinic. Colposcopic examination demonstrated a small polypoid lesion in the transformation zone. Microscopic examination of the biopsy specimen demonstrated papillary proliferation of the mucinous epithelium with bland nuclear morphology. Conization revealed lobular endocervical glandular hyperplasia (LEGH) with distinct nuclear anaplasia, as well as papillary proliferation of the mucinous epithelium with mild to moderate nuclear abnormalities. This case suggests that the incipient phase of PJS-associated MDA is related to atypical LEGH ("MDA in situ"), and indicates the importance of early screening and surveillance by gynecologists in cases of PJS to detect cervical adenocarcinomas.

    Objective At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. Methods Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. Results In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was 9.77 mm2 (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. Conclusions Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed. PMID:25328648

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Purpose: To report the outcomes and toxicities in patients treated with intensity-modulated radiotherapy (IMRT) for pancreatic adenocarcinoma. Methods and Materials: Forty-seven patients with pancreatic adenocarcinoma were treated with IMRT between 2003 and 2008. Of these 47 patients, 29 were treated adjuvantly and 18 definitively. All received concurrent 5-fluorouracil chemotherapy. The treatment plans were optimized such that 95% of the planning target volume received the prescription dose. The median delivered dose for the adjuvant and definitive patients was 50.4 and 54.0 Gy, respectively. Results: The median age at diagnosis was 63.9 years. For adjuvant patients, the 1- and 2-year overall survival rate was 79% and 40%, respectively. The 1- and 2-year recurrence-free survival rate was 58% and 17%, respectively. The local-regional control rate at 1 and 2 years was 92% and 80%, respectively. For definitive patients, the 1-year overall survival, recurrence-free survival, and local-regional control rate was 24%, 16%, and 64%, respectively. Four patients developed Grade 3 or greater acute toxicity (9%) and four developed Grade 3 late toxicity (9%). Conclusions: Survival for patients with pancreatic cancer remains poor. A small percentage of adjuvant patients have durable disease control, and with improved therapies, this proportion will increase. Systemic therapy offers the greatest opportunity. The present results have demonstrated that IMRT is well tolerated. Compared with those who received three-dimensional conformal radiotherapy in previously reported prospective clinical trials, patients with pancreatic adenocarcinoma treated with IMRT in our series had improved acute toxicity.

    Patients with pancreatic adenocarcinoma are known to have a high mortality rate. The 5-year survival rate still remains low even now compared to that of the 1960's despite new advances in management including surgery, chemotherapy, pathological classification and molecular diagnostic technologies. Precursors to invasive pancreatic adenocarcinoma have been identified in the last ten years that include mucinous cystic neoplasm, intraductal papillary mucinous neoplasm and pancreatic intraepithelial neoplasia. p53 protein accumulation in the nuclei is a common molecular event in most human neoplasms. Our objective is to investigate p53 expression in pancreatic adenocarcinoma and precursor lesions and their significance. The selected study material encompassed 31 invasive ductal adenocarcinoma, 15 mucinous cystic neoplasm and papillary mucinous neoplasm, and 27 cases of pancreatic intraepithelial neoplasia including grade 1, 2 and 3. Immunoscore was given for each case based on intensity of staining and percentage of cells positive and compared between precursor lesions and invasive adenocarcinoma. A score of 50 and above was considered significant. The results showed that p53 expression increased progressively and significantly with the grade of pancreatic intraepithelial neoplasia and adenocarcinoma (p-value < 0.001). These findings support the concept of multistep carcinogenesis in pancreatic adenocarcinoma and suggest that p53 inactivation occurs in the progression of precursors to pancreatic adenocarcinoma.

    Although embryonal proteins have been used as tumor marker, most are not useful for detection of early malignancy. In the present study, we developed mouse monoclonal antibodies against fetal lung of miniature swine, and screened them to find an embryonal protein that is produced at the early stage of malignancy, focusing on lung adenocarcinoma. We found an antibody clone that specifically stained stroma of lung adenocarcinoma. LC-MS/MS identified the protein recognized by this clone as dimethylarginine dimethylaminohydrolase 2 (DDAH2), an enzyme known for antiatherosclerotic activity. DDAH2 was found to be expressed in fibroblasts of stroma of malignancies, with higher expression in minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma than in adenocarcinoma in situ (AIS). Moreover, tumors with high stromal expression of DDAH2 had a poorer prognosis than those without. In vitro analysis showed that DDAH2 increases expression of endothelial nitric oxide synthase (eNOS), inducing proliferation and capillary-like tube formation of vascular endothelial cells. In resected human tissues, eNOS also showed higher expression in invasive adenocarcinoma than in AIS and normal lung, similarly to DDAH2. Our data indicate that expression of DDAH2 is associated with invasiveness of lung adenocarcinoma via tumor angiogenesis. DDAH2 expression might be a prognostic factor in lung adenocarcinoma.

    OBJECTIVE: To review the role of family physicians in screening for cancer of the cervix, to review the evidence for screening, in particular, frequency and technique for screening, and to review the reasons cervical cancer has not been prevented and the role of family physicians in addressing these failures. QUALITY OF EVIDENCE: The value of screening has been established with level II evidence. Many of the unresolved issues are not supported either way by good evidence; level II and III evidence predominates. MAIN FINDINGS: In Canada, 1350 women were predicted to be diagnosed with cancer of the cervix in 1996. Most of these women had not been screened. Minority, rural, low-income, and older women face important barriers to screening. Family physicians have a role in reaching out to these women to provide effective health care, including cancer screening. When cancer screening is performed, it should conform to recommended techniques with appropriate follow up of abnormal test results. CONCLUSIONS: Family physicians have an important role in preventing cancer of the cervix. Efforts should be concentrated on encouraging a greater proportion of eligible women to be screened. Criteria are suggested for effective screening. PMID:9721422

    2015-05-01

    OBJECT The cervical interfacet spacer (CIS) is a relatively new technology that can increase foraminal height and area by facet distraction. These offer the potential to provide indirect neuroforaminal decompression while simultaneously enhancing fusion potential due to the relatively large osteoconductive surface area and compressive forces exerted on the grafts. These potential benefits, along with the relative ease of implantation during posterior cervical fusion procedures, make the CIS an attractive adjuvant in the management of cervical pathology. One concern with the use of interfacet spacers is the theoretical risk of inducing iatrogenic kyphosis. This work tests the hypothesis that interfacet spacers are associated with loss of cervical lordosis. METHODS Records from patients undergoing posterior cervical fusion at Rush University Medical Center between March 2011 and December 2012 were reviewed. The FacetLift CISs were used in all patients. Preoperative and postoperative radiographic data were reviewed and the Ishihara indices and cervical lordotic angles were measured and recorded. Statistical analyses were performed using STATA software. RESULTS A total of 64 patients were identified in whom 154 cervical levels were implanted with machined allograft interfacet spacers. Of these, 15 patients underwent anterior-posterior fusions, 4 underwent anterior-posterior-anterior fusions, and the remaining 45 patients underwent posterior-only fusions. In the 45 patients with posterior-only fusions, a total of 110 levels were treated with spacers. There were 14 patients (31%) with a single level treated, 16 patients (36%) with two levels treated, 5 patients (11%) with three levels treated, 5 patients (11%) with four levels treated, 1 patient (2%) with five levels treated, and 4 patients (9%) with six levels treated. Complete radiographic data were available in 38 of 45 patients (84%). On average, radiographic follow-up was obtained at 256.9 days (range 48-524 days

    2003-01-01

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.

    2010-01-01

    Adenocarcinoma of the exocrine pancreas has an annual incidence of 7,400 cases in the U.K. In comparison with other common cancers of solid organs, namely, breast, colorectal, and prostate cancer, pancreatic cancer has a high morbidity and mortality. Radical resection is possible in only 15%-20% of patients, and only 3%-4% of all patients presenting with this condition achieve long-term control and cure. Various strategies in the form of neoadjuvant and adjuvant treatment have been employed over the years to improve outcome, with limited success. Systemic chemotherapy remains the gold standard in the metastatic setting in good performance status patients, and adjuvant chemotherapy after resection of localized and locally advanced cancer has been found to improve outcome. The role of radiotherapy, however, remains controversial and is an area that merits further investigation in well-conducted multicenter trials at various stages of the disease in combination with systemic agents and exploiting recent advances in the delivery of radiotherapy. In this article, we review the published literature on the use of chemoradiation as a modality in various stages of pancreatic adenocarcinoma and highlight areas that future trials in this field should target for a way forward in this malignancy.

    Pancreatic adenocarcinoma is the fourth leading cause of cancer mortality in the United States in both men and women, with a 5-year survival rate of less than 5%. Surgical resection remains the only curative treatment, but most patients develop systemic recurrence within 2 years of surgery. Adjuvant treatment with chemotherapy or chemoradiotherapy has been shown to improve overall survival, but the delivery of treatment remains problematic with up to 50% of patients not receiving postoperative treatment. Neoadjuvant therapy can provide benefits of eradication of micrometastasis and improved delivery of intended treatment. We have reviewed the findings from completed neoadjuvant clinical trials, and discussed the ongoing studies. Combinational cytotoxic chemotherapy such as fluorouracil, leucovorin, irinotecan, and oxaliplatin and gemcitabine plus nanoparticle albumin-bound (nab)-paclitaxel, active in the metastatic setting, are being studied in the neoadjuvant setting. In addition, novel targeted agents such as inhibitor of immune checkpoint are incorporated with cytotoxic chemotherapy in early-phase clinical trial. Furthermore we have explored the utility of biomarkers which can personalize treatment and select patients for target-driven therapy to improve treatment outcome. The treatment of resectable pancreatic adenocarcinoma requires multidisciplinary approach and novel strategies including innovative trials to make progress. PMID:26862486

    Abstract Introduction: Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland tumor that is found on the fingers, toes, and the digits. To date, <100 cases have been reported in the literature. Apart from 1 case reported in the thigh, all of them were on digital or nondigital acral skin. Case presentation: A 67-year-old Caucasian woman was admitted to the hospital due to a mass on the scalp. This lesion was present for almost a year. It was a semimobile cyctic mass that elevated the scalp. There was no change in the skin color. Its dimensions were 1.5 × 1 × 0.6 cm. The laboratory, clinic, and radiologic findings (head x-ray) of the patient were normal. It was evaluated as a benign lesion such as lipoma or epidermal cyst by a surgeon due to a small semimobile mass and no erosion of the skull. It was excised by a local surgery excision. The result of the pathologic examination was aggressive papillary adenocarcinoma. This diagnosis is synonymous with ADPA. Conclusion: In our case, localization was scalp. This localization is the first for this tumor in the literature. In addition, another atypical localization of this tumor (ADPA) is thigh in the literature. This case was presented due to both the rare and atypical localizations. That is why, in our opinion, revision of “digital” term in ADPA is necessary due to seem in atypical localizations like thigh and scalp. PMID:27428196

Combinational cytotoxic chemotherapy such as fluorouracil, leucovorin, irinotecan, and oxaliplatin and gemcitabine plus nanoparticle albumin-bound (nab)-paclitaxel, active in the metastatic setting, are being studied in the neoadjuvant setting. In addition, novel targeted agents such as inhibitor of immune checkpoint are incorporated with cytotoxic chemotherapy in early-phase clinical trial. Furthermore we have explored the utility of biomarkers which can personalize treatment and select patients for target-driven therapy to improve treatment outcome. The treatment of resectable pancreatic adenocarcinoma requires multidisciplinary approach and novel strategies including innovative trials to make progress. PMID:26862486

    Background: Data from Egyptian studies provide widely varying estimates on the prevalence of preinvasive cervical lesions. The aim of this study was to estimate the rate of cervical intraepithelial neoplasia (CIN) in Egyptian women living in Alexandria to clarify the need for implementing a national organized screening program and a vaccination program in our community. Materials and Methods: The study was conducted over a 6 years period and covered the different socioeconomic levels to have a representative sample for women living in Alexandria. All women included did not have any cervical disorder related complaints. Conventional Pap smears were obtained and diagnosed using the Bethesda system. Women with abnormal Pap smears were managed according to the 2006 consensus guidelines within the available facilities. Persistent abnormal cytological results were referred for colposcopic biopsy. Histological results were grouped into: Reactive changes, CIN 1, CIN 2/CIN 3 and adenocarcinoma in-situ (AIS). Results: Out of the 6173 smears included in the study 6072 (98.36%) were normal and only 101 (1.63%) were abnormal. After colposcopic biopsies, 0.08% had CIN 1, 0.03% had CIN 2, 3 and 0.01% had AIS. Conclusion: We concluded that cervical cancer screening programs, although life-saving for a number of women, are not a sufficiently high priority in our community. Money for national health screening programs should preferably be directed more towards recruiting women for breast cancer screening, since breast cancer accounts for about 33% of all female cancers in Egypt ranking number one, while cervical cancer ranks number 13.

    Dermoid cysts are common benign ovarian germ cell neoplasms. Occasionally, one of the mature elements undergoes malignant transformation resulting in the formation of a somatic malignancy; most commonly this is squamous carcinoma. We report a unique case where 2 separate malignancies arose within a dermoid cyst, one a signet ring mucinous adenocarcinoma and the other a pulmonary-type adenocarcinoma. There have been only occasional earlier case reports of a possible pulmonary-type adenocarcinoma arising in a dermoid cyst. In the case we report, the pulmonary-type adenocarcinoma was closely associated with a bronchial structure and exhibited diffuse positive immunohistochemical staining with TTF1, PE10, and napsin A. Molecular studies revealed no evidence of epidermal growth factor receptor mutation, a molecular alteration which may be found in primary pulmonary adenocarcinoma. PMID:23026196

    Purpose: To determine the effectiveness and rate of complications of intensity-modulated radiotherapy (IMRT) in the treatment of cervical lymph node metastases from unknown primary cancer. Methods and Materials: Between February 2005 and November 2008, 25 patients with an unknown primary cancer underwent IMRT, with a median radiation dose of 70 Gy. The bilateral neck and ipsilateral putative pharyngeal mucosa were included in the target volume. All patients had squamous cell carcinoma, except for 1 patient who had adenosquamous differentiation. They were all treated with curative intent. Of the 25 included patients, 20 were men and 5 were women, with a median age of 54 years. Of these patients, 3 had Stage III, 18 had Stage IVa, and 4 had Stage IVb. Of the 25 patients, 18 (72%) received platinum-based chemotherapy in a combined-modality setting. Neck dissection was reserved for residual disease after definitive IMRT. Overall survival, disease-free survival, and locoregional control were calculated using the Kaplan-Meier method. Results: With a median follow-up of 38 months, the overall survival, disease-free survival, and locoregional control rates were all 100% at 3 years. No occurrence of primary cancer was observed during the follow-up period. The reported rates of xerostomia reduced with the interval from the completion of treatment. Nine patients (36%) reported Grade 2 or greater xerostomia at 6 months, and only 2 (8%) of them reported the same grade of salivary function toxicity after 24 months of follow-up. Conclusion: In our institution, IMRT for unknown primary cancer has provided good overall and disease-free survival in all the patients with an acceptable rate of complications. IMRT allowed us to address the bilateral neck and ipsilateral putative pharyngeal mucosa with minimal late salivary function toxicity. The use of concurrent chemotherapy and IMRT for more advanced disease led to good clinical results with reasonable toxicities.

    The increasing occurrence of dental lesions at the cervical surfaces requires more knowledge of the causes of the process. Acidic and abrasive mechanisms have clearly been documented as causes but the stress theory by Lee and Eakle is still controversial. This report describes several incidences of possible stress-induced lesions according to the characteristics described by Lee and Eakle. The occurrences of subgingival lesions lend credence to the stress-induction theory by exclusion of other superimposing etiologic factors. With the current concepts, a perceptive approach to the treatment of cervical lesions can be executed. PMID:1527763

    Abfraction or Theory of Abfraction is a theory explaining the non-carious cervical lesions (NCCL). It suggests that they are caused by flexural forces, usually from cyclic loading; the enamel, especially at the cementoenamel junction (CEJ), undergoes this pattern of destruction by separating the enamel rods. Clinical aspect importance of these ineart lesions are at most important to be detected for early intervention and treatment modalities as options during the progression of the disease.

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Percutaneous disc decompression procedures have been performed in the past. Various percutaneous techniques such as percutaneous discectomy, laser discectomy, and nucleoplasty have been successful. Our prospective study was directly to evaluate the results of percutaneous cervical nucleoplasty (PCN) surgery for cervical disc herniation, and illustrate the effectiveness of PCN in symptomatic patients who had cervical herniated discs. From July of 2002 to June of 2005, 126 consecutive patients with contained cervical disc herniations have presented at the authors’ clinic and treated by PCN. The patients’ gender distribution for PCN was 65 male, 61 female. The age of patients ranged from 34 to 66 years (mean 51.9 ± 10.2 years). The levels of involvement were 21 cases at C3–4, 30 cases at C4–5, 40 cases at C5–6, and 35 cases at C6–7. The clinical outcomes, pain reduction and the segment stability were all recorded during this study. A clinical outcome was quantified by the Macnab standard and using VAS. The angular displacement (AD) ≥11° or horizontal displacement (HD) ≥3 mm was considered to be radiographically unstable. In the results of this study, puncture of the needle into the disc space was accurately performed under X-ray guidance in all cases. There was one case where the Perc-D Spine Wand had broken in the disc space during the procedure. The partial Perc-D Spine Wand, which had broken in the disc space could not be removed by the percutaneous cervical discectomy and thus remained there. There were no recurrent cases or complications in our series. Macnab standard results were excellent in 62 cases, good in 41 cases and fair in 23 cases. The rate of excellent and good was 83.73%. The VAS scores demonstrated statistically significant improvement in PCN at the 2-week, 1, 3, 6, and 12-month follow-up visits when compared to preoperational values (P < 0.01). There were no cases of instability following the PCN procedure. There was no

    The aim of this study was to estimate the effect of exposure to secondhand tobacco smoke on the incidence of lung adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA). Data from seven case-control studies participating in the International Lung Cancer Consortium (ILCCO) were pooled, resulting in 625 cases of AIS/MIA and 7,403 controls, of whom 170 cases and 3,035 controls were never smokers. Unconditional logistic regression was used to estimate adjusted ORs (ORadj) and 95% confidence intervals (CI), controlling for age, sex, race, smoking status (ever/never), and pack-years of smoking. Study center was included in the models as a random-effects intercept term. Ever versus never exposure to secondhand tobacco smoke was positively associated with AIS/MIA incidence in all subjects (ORadj = 1.48; 95% CI, 1.14-1.93) and in never smokers (ORadj = 1.45; 95% CI, 1.00-2.12). There was, however, appreciable heterogeneity of ORadj across studies (P = 0.01), and the pooled estimates were largely influenced by one large study (40% of all cases and 30% of all controls). These findings provide weak evidence for an effect of secondhand tobacco smoke exposure on AIS/MIA incidence. Further studies are needed to assess the impact of secondhand tobacco smoke exposure using the newly recommended classification of subtypes of lung adenocarcinoma. PMID:26503035

    A 35-year-old woman underwent laparoscopic radical hysterectomy, pelvic lymphadenectomy and ovarian transposition for stage IB2 cervical adenocarcinoma. She received adjuvant concurrent chemoradiation for poor pathologic risk factors but had tumor recurrence 20 months after the surgery. Transposed ovaries were uninvolved in the recurrence and progression. Salvage chemotherapy and radiotherapy were given. Despite systemic chemotherapy and repeat pelvic radiotherapy, the patient was able to maintain ovarian function. Ovarian transposition in cervical cancer is an easily performed procedure that does not alter the prognosis of the disease in some cases. Present recommendations for its use should be reevaluated so that more premenopausal cancer patients may benefit from this underutilized procedure. PMID:23653838

    A continuous cell line, COLO 346, was established from a liver metastasis in a patient with adenocarcinoma of the gallbladder. COLO 346 grew as an adherent monolayer of pleomorphic epithelioid cells. COLO 346 cells produced esterone, but no estradiol, progesterone, or cortisol. No adrenocorticotropic hormones, beta-subunit of human chorionic gonadotropin, carcinoembryonic antigen, or alpha-fetoprotein production by the cells was detected. Cell doubling time was 36 h. Seven allelic isozymes were assayed. COLO 346 had a chromosome mode of 74 at 21 months postestablishment with 6 marker chromosomes present in 100% of the cells analyzed. COLO 346 has been in continuous culture for over 2 yr and is available to other investigators for their studies. PMID:7262900

    A 73-year-old postmenopausal Japanese woman presented with a complaint of slight fever and weight loss. An elevated level of CA125 in the blood favored a diagnosis of malignant uterine body tumor, but was not confirmed by endometrial cytology and biopsy. Resection of the uterus revealed a solid whitish tumor in the myometrium that was diagnosed as clear cell adenocarcinoma (CCA) arising from adenomyosis. There were transitions between endometrial epithelium of adenomyosis, noninvasive CCA, and invasive CCA. Immunohistochemical expression of hepatocyte nuclear factor-1beta supported the diagnosis of CCA. Only one other English language document pertaining to CCA arising from adenomyosis exists. Malignant tumor arising from adenomyosis should be considered as a differential diagnosis when the serum level of tumor markers such as CA125 is high and when the tumor is intramyometrial.

    Pancreatic ductal adenocarcinoma (PDAC) is expected to become the second leading cause of cancer death by 2030. Current therapeutic options are limited, warranting an urgent need to explore innovative treatment strategies. Due to specific microenvironment constraints including an extensive desmoplastic stroma reaction, PDAC faces major metabolic challenges, principally hypoxia and nutrient deprivation. Their connection with oncogenic alterations such as KRAS mutations has brought metabolic reprogramming to the forefront of PDAC therapeutic research. The Warburg effect, glutamine addiction, and autophagy stand as the most important adaptive metabolic mechanisms of cancer cells themselves, however metabolic reprogramming is also an important feature of the tumor microenvironment, having a major impact on epigenetic reprogramming and tumor cell interactions with its complex stroma. We present a comprehensive overview of the main metabolic adaptations contributing to PDAC development and progression. A review of current and future therapies targeting this range of metabolic pathways is provided. PMID:26164081

    Adenocarcinoma of the pigmented ciliary epithelium is an exceptionally rare eye tumour, with only a few cases reported to date. We encountered such a case in a 50-year-old woman who reported seeing floaters in her right eye. Fundus examination and MRI revealed an elevated lesion located in the ciliary body compressing the lens. The ciliary body was resected under the diagnosis of ciliary adenoma. On histological examination, the tumour exhibited epithelial features with glandular formation and moderate nuclear pleomorphism. The tumour invaded the subepithelial stroma of the ciliary body. Immunohistochemical findings were positive for cytokeratin OSCAR, AE1/AE3, CK7, EMA, S100, Melan A, HMB45, and microphthalmia-associated transcription factor. PMID:25015166

    Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA, accounting for ~40,000 deaths annually. The dismal prognosis for PDAC is largely due to its late diagnosis. Currently, the most sensitive diagnosis of PDAC requires invasive procedures, such as endoscopic ultrasonography, which has inherent risks and accuracy that is highly operator dependent. Here we took advantage of a general characteristic of solid tumors, the acidic microenvironment that is generated as a by-product of metabolism, to develop a novel approach of using pH (Low) Insertion Peptides (pHLIPs) for imaging of PDAC. We show that fluorescently labeled pHLIPs can localize and specifically detect PDAC in human xenografts as well as PDAC and PanIN lesions in genetically engineered mouse models. This novel approach may improve detection, differential diagnosis and staging of PDAC.

    Pancreatic ductal adenocarcinoma (PDAC) is one of the most common causes of cancer related death. Despite the advances in understanding of the molecular pathogenesis, pancreatic cancer remains a major unsolved health problem. Overall, the 5-year survival rate is less than 5% demonstrating the insufficiency of current therapies. Most cytotoxic therapies induce apoptosis and PDAC cells have evolved a plethora of molecular mechanisms to assure survival. We will present anti-apoptotic strategies working at the level of the death receptors, the mitochondria or involving the caspase inhibitors of the IAP family. Furthermore, the survival function of the phosphotidylinositol-3' kinase (PI3K)/AKT- and NF-kappaB-pathways are illustrated. A detailed molecular knowledge of the anti-apoptotic mechanisms of PDAC cells will help to improve therapies for this dismal disease and therapeutic strategies targeting the programmed cell death machinery are in early preclinical and clinical development.

    The study revealed the key role of serine protease hepsin activity in transition of in situ prostate adenocarcinoma into the metastasizing form. Inhibition of hepsin activity suppresses the invasive growth of the tumor. Hepsin is an convenient target for pharmacological agents, so the study of its inhibitory mechanisms is a promising avenue in drug development. Assay of proteolytic activity in various tumor cell lines in vitro showed that this activity in prostate adenocarcinoma cells significantly surpasses proteolytic activity in other examined tumor cell lines. Selective cytotoxic action of anthralin, an inhibitor of hepsin activity, on human adenocarcinoma cells was demonstrated in comparison with other tumor cell lines. PMID:22866312

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    We studied the pattern of aberrant methylation during the multistage pathogenesis of cervical cancers. We analyzed a total of 73 patient samples and 10 cervical cancer cell lines. In addition, tissue samples [peripheral blood lymphocytes (n = 10) and buccal epithelial cells (n = 12)] were obtained from 22 healthy volunteers. On the basis of the results of preliminary analysis, the cervical samples were grouped into three categories: (a) nondysplasia/low-grade cervical intraepithelial neoplasia (CIN; n = 37); (b) high-grade CIN (n = 17); and (c) invasive cancer (n = 19). The methylation status of six genes was determined (p16, RARbeta, FHIT, GSTP1, MGMT, and hMLH1). Our main findings are as follows: (a) methylation was completely absent in control tissues; (b) the frequencies of methylation for all of the genes except hMLH1 were >20% in cervical cancers; (c) aberrant methylation commenced early during multistage pathogenesis and methylation of at least one gene was noted in 30% of the nondysplasia/low-grade CIN group; (d) an increasing trend for methylation was seen with increasing pathological change; (e) methylation of RARbeta and GSTP1 were early events, p16 and MGMT methylation were intermediate events, and FHIT methylation was a late, tumor-associated event; and (f) methylation occurred independently of other risk factors including papillomavirus infection, smoking history, or hormone use. Although our findings need to be extended to a larger series, they suggest that the pattern of aberrant methylation in women with or without dysplasia may help identify subgroups at increased risk for histological progression or cancer development.

    Cervical cancer remains a major cause of morbidity and mortality among women, especially in the developing world. Increased synthesis of proteins, lipids and nucleic acids is a pre-condition for the rapid proliferation of cancer cells. We show that scanning near-field optical microscopy, in combination with an infrared free electron laser (SNOM-IR-FEL), is able to distinguish between normal and squamous low-grade and high-grade dyskaryosis, and between normal and mixed squamous/glandular pre-invasive and adenocarcinoma cervical lesions, at designated wavelengths associated with DNA, Amide I/II and lipids. These findings evidence the promise of the SNOM-IR-FEL technique in obtaining chemical information relevant to the detection of cervical cell abnormalities and cancer diagnosis at spatial resolutions below the diffraction limit (≥0.2 μm). We compare these results with analyses following attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy; although this latter approach has been demonstrated to detect underlying cervical atypia missed by conventional cytology, it is limited by a spatial resolution of ~3 μm to 30 μm due to the optical diffraction limit.

    Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging. PMID:27273940

    Prostatic adenocarcinoma is the most common cancer in men, but only a handful of cases of prostatic angiosarcoma have been reported in the literature. Prior radiation therapy for prostatic adenocarcinoma has been hypothesized to be a risk factor for angiosarcoma. The increasing practice of prostate cancer screening and the use of radiation therapy for management of prostatic adenocarcinoma will likely lead to more cases of prostatic angiosarcoma. Diagnosis is made by tissue sampling. Optimal management of these aggressive tumors remains to be defined and outcomes are poor with a high 1-year mortality. Primary care physicians and urologists should be aware of this rare entity and refer these patients to specialist centers where they can be managed by a multidisciplinary team. We report a case of angiosarcoma of the prostate gland diagnosed in a male presenting with lower urinary tract symptoms 5 years after brachytherapy for prostate adenocarcinoma. PMID:26889128

    Injuries of the upper cervical spine represent 1/3 of all cervical spine injuries and approximately 40 % result by the death. Every level of the cervical spine can be injured - fractures of condyles of the occipital bone (CO), atlantooccipital dislocation (AOD), fractures of the Atlas (C1), atlantoaxial dislocation (AAD) and fractures of the axis (C2). Most of cases in younger patients are caused by high-energy trauma, while by elderly people, because of the osteoporosis, is needed much less energy and even simple falls can cause the injury of the cervical spine. That´s why the etiology of injuries can be different. In younger patients are caused mainly by car accidents, motorcycle and bicycle accidents and pedestrian crashes by car and in elderly populations are the main reason falls. The mechanism of the injury is axial force, hyperflexion, hyperextension, latero-flexion, rotation and combination of all. The basic diagnostic examination is X ray in AP, lateral and transoral projection. But in the most of cases is CT examination necessary and in the suspicion of the ligamentous injury and neurological deterioration must be MRI examination added. Every injury of the upper cervical spine has its own classification. Clinical symptoms can vary from the neck pain, restricted range of motion, antalgic position of the head, injury of the cranial nerves and different neurologic symptoms from the irritation of nerves to quadriplegia. A large percentage of deaths is at the time of the injury. Therapy is divided to conservative treatment, which is indicated in bone injuries with minimal dislocation. In more severe cases, with the dislocation and ligamentous injury, when is high chance of the instability, is indicated the surgical treatment. We can use anterior or posterior approach, make the osteosynthesis, stabilisation and fusion of the spine. Complex fractures and combination of different types of injuries are often present in this part of the spine. Correct and early

    2015-03-01

    Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

    2012-01-01

    Background: Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered. Numerous US investigational device exemption trials comparing cervical arthroplasty to fusion have been conducted to answer this question. Methods: This study reviews the current research regarding cervical athroplasty, and emphasizes both the pros and cons of arthroplasty as compared with ACDF. Results: Early clinical outcomes show that cervical arthroplasty is as effective as the standard ACDF. However, this new technology is also associated with an expanding list of novel complications. Conclusion: Although there is no definitive evidence that cervical disc replacement reduces the incidence of adjacent segment degeneration, it does show other advantages; for example, faster return to work, and reduced need for postoperative bracing.

    The NCCN Guidelines for Cervical Cancer provide interdisciplinary recommendations for treating cervical cancer. These NCCN Guidelines Insights summarize the NCCN Cervical Cancer Panel's discussion and major guideline updates from 2014 and 2015. The recommended systemic therapy options for recurrent and metastatic cervical cancer were amended upon panel review of new survival data and the FDA's approval of bevacizumab for treating late-stage cervical cancer. This article outlines relevant data and provides insight into panel decisions regarding various combination regimens. Additionally, a new section was added to provide additional guidance on key principles of evaluation and surgical staging in cervical cancer. This article highlights 2 areas of active investigation and debate from this new section: sentinel lymph node mapping and fertility-sparing treatment approaches. PMID:25870376

    Objective Our study aims to describe changes in carcinoma in situ (CIS) and invasive cervical carcinoma (ICC) in Korean women diagnosed between 1993 and 2009. Methods All cases of CIS and invasive cervical carcinoma diagnosed from 1993 to 2009 in the Korean National Cancer Incidence database were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) in incidence rates were compared according to age and histological type. Additionally, we used Korea National Health and Nutrition Examination Survey (KNHANES) to know the association between screening rate for cervical cancer and incidence rate of cervical cancer. Results Between 1993 and 2009, 72,240 cases of ICC were reported in Korea. Total incidence rate of ICC was 14.7 per 100,000 females. ASRs of ICC declined 3.8% per year, from 19.3 per 100,000 in 1993 to 10.5 per 100,000 in 2009. Although the overall incidence rate of adenocarcinoma remained stable, invasive squamous cell carcinoma showed a decreasing trend (APC −4.2%). For women aged 60–79 years, ASRs for squamous cell carcinoma increased from 1993 to 2001, and decreased from 2001 to 2009 (APC: −4.6%). Total 62,300 cases of CIS were diagnosed from 1993 to 2009. Total incidence rate of CIS was 12.2 per 100,000 females. ASRs of CIS increased 5.7% per year, from 7.5 per 100,000 in 1993 to 19.0 per 100,000 in 2009. Adenocarcinoma in situ increased 13.2% per year. There was a strong positive correlation between screening rate for cervical cancer and incidence rate for CIS (p-value = 0.03) whereas screening rate showed a strong negative correlation with incidence rate for squamous ICC (p-value = 0.04). Conclusions The increasing trend in CIS, coupled with a decreasing trend in ICC, suggests the important role of cervix cancer screening. The incidence of adenocarcinoma showed a plateau, but the incidence of adenocarcinoma in situ showed an increasing trend. PMID:23977194

    Background There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19–9 (CA 19–9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies. Methods CA 19–9, carcinoembryonic antigen (CEA), C-reactive protein, albumin, insulin growth factor-1 (IGF-1) and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls. Results The combination of CA 19–9, IGF-1 and albumin resulted in a combined area under the curve (AUC) of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19–9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients. Conclusions Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

    Pancreatic adenocarcinoma up-regulated factor (PAUF) expression is elevated in both ovarian tumors and pancreatic adenocarcinoma. However, PAUF expression in ovarian tumors according to histologic subtype and grade has not been investigated. In this study, we examined various clinicopathologic features of 24 patients with mucinous cystadenoma (MCA), 36 with mucinous borderline tumors (MBTs), and 46 with mucinous adenocarcinomas (MACs) according to PAUF expression status assessed using immunohistochemistry. We found that MACs more frequently stained positive for PAUF than did MCAs and MBTs (P < 0.0001). Although there was no significant differences with respect to other clinicopathologic characteristics of MACs according to PAUF expression status, patients with PAUF-weakly positive and PAUF-strongly positive MACs tended to have a shorter overall survival (OS) than those with PAUF-negative MAC, determined using a Kaplan-Meier analysis (P = 0.1885). After adjusting for various clinicopathologic parameters, PAUF positivity of MACs was a significant predictive factor for disease-free survival (DFS) (negative vs. weakly positive: P = 0.045, hazard ratio [HR] = 57.406, 95% confidence interval [CI]: 1.090-3022.596; and negative vs. strongly positive: P = 0.034, HR = 97.890, 95% CI: 1.412-6785.925). In conclusion, PAUF was more frequently expressed in MAC than in its benign and borderline counterparts, and was associated with a poor OS and DFS in MAC patients. Therefore, we suggest that PAUF may be a practical biomarker for histopathological categorization and a prognostic marker for patients with an ovarian mucinous tumor. PMID:25197383

    We present the first described case of cervical vertebral fusion associated with anterior meningocele and syringomyelia. A 45-year-old woman presented with minor trauma, and plain cervical spine radiographs highlighted a congenital deformity of the cervical vertebral bodies. She had a normal neurological examination; however, further imaging revealed a meningocele and syringomyelia. This case highlights the importance of thorough imaging investigation when presented with a congenital deformity in order to detect and prevent development of degenerative spinal cord pathologies.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Evaluation of cervical mucus is a standard for determining the fertile period in natural family planning. Cervical mucus accepts, filters, prepares, and releases sperm for successful transport to the egg and fertilization. Recent scientific advances provide answers to how the mucus regulates fertility as its physical properties change during the menstrual cycle. Transmission electron microscopy reveals small interstices between mucus macromolecules relative to a sperm head. Thus advancing sperm must push aside or cut through the microstructure. The interstices are largest in the periovulatory phase of the cycle. Small magnetic spheres, comparable with the size of a sperm head, are now being used to study the physical properties of the mucus on the scale of individual sperm. PMID:1755453

    Background: Noncontiguous cervical spondylotic myelopathy (CSM) is a special degenerative disease because of the intermediate normal level or levels between supra and infraabnormal levels. Some controversy exists over the optimal procedure for two noncontiguous levels of CSM. The study was to evaluate the outcomes of the anterior cervical discectomy and fusion (ACDF) with zero-profile devices for two noncontiguous levels of CSM. Materials and Methods: 17 consecutive patients with two noncontiguous levels of CSM operated between December 2009 and August 2012 were included in the study. There were 12 men and 5 women with a mean age of 60.7 years (range 45–75 years). Involved disc levels were C3/4 and C5/6 in 11 patients and C4/5 and C6/7 in six patients. Preoperative plain radiographs, computed tomography (CT) with 3-D reconstruction and magnetic resonance imaging (MRI) of the cervical spine were taken in all patients. All radiographs were independently evaluated by 2 spine surgeons and 1 radiologist. The outcomes were assessed by the average operative time, blood loss, Japanese Orthopedic Association (JOA) score, improvement rate, neck dysfunction index (NDI), swallowing quality of life (SWAL-QOL) score, the cervical lordosis and complications. Results: The mean followup was 48.59 months (range 24-56 months). The average operative time and blood loss was 105.29 min and 136.47 ml, respectively. The preoperative JOA score was 8.35, which significantly increased to 13.7 at the final followup (P < 0.01). The NDI score was significantly decreased from preoperative 13.06 to postoperative 3.35 (P < 0.01). The operation also provided a significant increase in the cervical lordosis (P < 0.01) from preoperative 10.17° to postoperative 17.06°. The fusion rate was 94.1% at 6 months postoperatively, and 100% at 12 months after surgery. The mean SWAL-QOL score decreased from preoperative 68.06 to immediate postoperatively 65.65 and then increased to 67.65 at final followup

    An adult female baboon (Papio cynocephalus anubis) presented for progressive difficulty in endotracheal intubation. Over a 7-y period prior to presentation, she was anesthetized and intubated 67 times for imaging by using single-photon emission computed tomography or positron emission tomography. Laryngoscopic examination revealed tracheal stenosis. Because of increased anesthetic risk and lack of alternative use, she was euthanized, and partial necropsy focusing on the larynx, trachea, and associated structures was performed. Gross examination revealed rigidity and functional fusion of the proximal 5 or 6 tracheal rings and narrowing of the lumen. Histology revealed ossification of tracheal rings and fibrosis of overlying tissue. In addition, a transmural umbilicated mass was present midway down the cervical trachea on its dorsolateral aspect. Histology of the tracheal mass identified a relatively well-circumscribed transmural adenocarcinoma. The combination of overall histologic pattern, evidence of anaplasia, and results of immunohistochemical staining was consistent with a diagnosis of adenoid cystic carcinoma. Anterior tracheal stenosis is a reported complication of intubation in humans and animals. Primary tracheal neoplasms are rare in domestic and research animals and, to our knowledge, have not previously been reported to occur in nonhuman primates. PMID:22330583

    Sixteen cases of mucinous adenocarcinoma of the cervix that were associated with a mucinous tumor of one or both ovaries are reported. The patients ranged from 25 to 70 (average, 44) years of age; two of them had the Peutz-Jeghers syndrome. Eight patients complained of abdominal swelling; most of the remainder had symptoms of uterine origin. Twelve patients had bilateral and four had unilateral ovarian tumors, which were typically large and cystic. Microscopic examination of most of the ovarian tumors revealed various combinations of benign-appearing, borderline, and carcinomatous mucinous epithelium within the same specimen. Most of the cervical tumors were deeply invasive; 10 of them were of the adenoma malignum type. Although there were varying degrees of uncertainty in individual cases, consideration of several features including the extent and distribution of disease in the abdomen, the comparative histology of the tumors, and the pattern of ovarian involvement suggested that 10 of the ovarian tumors were independent primary tumors, three were metastatic from the cervix, and in three cases the ovaries contained both primary and metastatic tumors.

    Objective High-risk HPV (hrHPV) and cytology co-testing is utilized for primary cervical cancer screening and for enhanced follow-up of women who are hrHPV-positive, cytology negative. However, data are lacking on the utility of this method to detect pre-cancer or cancer in community-based clinical practice. This study describes cytology and hrHPV results preceding high-grade cervical intraepithelial neoplasia, adenocarcinoma in situ, or cervical cancer (i.e., CIN2+) in an integrated health system employing routine co-testing among women aged 30 years and older. Methods We conducted a cross-sectional analysis of adult female members of Kaiser Permanente Northern California (KPNC) with incident CIN2+ between July 2008 and June 2009. The primary outcome was the proportions of cytologic diagnoses and hrHPV co-test results preceding a diagnosis of CIN2+. Cervical cytology and hrHPV testing results were abstracted from electronic medical records. Results Of 1283 CIN2+ cases among adult women, 880 (68.5%) were among women aged 30 years and older and 145/880 (16.5%, 95% CI 14.1–19.1) had only normal cytology during the 12 months prior to diagnosis. Furthermore, 133/880 (15.1%, 95% 12.9–17.7) were preceded by only normal cytology and persistent hrHPV infection (at least 2 positive hrHPV tests) during the 6–36 months preceding CIN2+ diagnosis. Conclusions Incident CIN2+ is frequently preceded by normal cytology and persistent hrHPV infection among women aged 30 years and older; screening strategies that employ HPV testing and cytology may improve the detection of CIN2+ compared with cytology alone.

    Background Cervical intraepithelial neoplasia (CIN) is the most common pre-malignant lesion. Atypical squamous changes occur in the transformation zone of the cervix with mild, moderate or severe changes described by their depth (CIN 1, 2 or 3). Cervical intraepithelial neoplasia is treated by local ablation or lower morbidity excision techniques. Choice of treatment depends on the grade and extent of the disease. Objectives To assess the effectiveness and safety of alternative surgical treatments for CIN. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (up to April 2009). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. Selection criteria Randomised controlled trials (RCTs) of alternative surgical treatments in women with cervical intraepithelial neoplasia. Data collection and analysis Two review authors independently abstracted data and assessed risks of bias. Risk ratios that compared residual disease after the follow-up examination and adverse events in women who received one of either laser ablation, laser conisation, large loop excision of the transformation zone (LLETZ), knife conisation or cryotherapy were pooled in random-effects model meta-analyses. Main results Twenty-nine trials were included. Seven surgical techniques were tested in various comparisons. No significant differences in treatment failures were demonstrated in terms of persistent disease after treatment. Large loop excision of the transformation zone appeared to provide the most reliable specimens for histology with the least morbidity. Morbidity was lower than with laser conisation, although the trials did not provide data for every outcome measure. There were not enough data to assess the effect on morbidity when compared with laser ablation. Authors’ conclusions The evidence

    Carriers of germline mutations in DNA mismatch repair (MMR) genes are at increased risk of several cancers including colorectal and gynecologic cancers (Lynch syndrome). There is no substantial evidence that these mutations are associated with an increased risk of cervical cancer. A total of 369 families with at least one carrier of a mutation in a MMR gene (133 MLH1, 174 MSH2, 35 MSH6 and 27 PMS2) were ascertained via population cancer registries or via family cancer clinics in Australia, New Zealand, Canada, and USA. Personal and family histories of cancer were obtained from participant interviews. Modified segregation analysis was used to estimate the hazard ratio (incidence rates for carriers relative to those for the general population), and age-specific cumulative risks of cervical cancer for carriers. A total of 65 cases of cervical cancer were reported (including 10 verified by pathology reports). The estimated incidence was 5.6 fold (95% CI: 2.3-13.8; p = 0.001) higher for carriers than for the general population with a corresponding cumulative risk to 80 years of 4.5% (95% CI: 1.9-10.7%) compared with 0.8% for the general population. The mean age at diagnosis was 43.1 years (95% CI: 40.0-46.2), 3.9 years younger than the reported USA population mean of 47.0 years (p = 0.02). Women with MMR gene mutations were found to have an increased risk of cervical cancer. Due to limited pathology verification we cannot be certain that a proportion of these cases were not lower uterine segment endometrial cancers involving the endocervix, a recognized cancer of Lynch syndrome.

The diagnostic value of HE4 in pancreatic adenocarcinoma remains unknown. Here we elucidate mRNA, protein and serum level of HE4 in pancreatic adenocarcinoma. HE4 mRNA level in tumor adjacent tissues and pancreatic adenocarcinoma tissues were tested by real time-PCR. Tissue microarray containing normal, adenocarcinoma, and adjacent pancreatic tissue was tested by immunohistochemistry (IHC). Serum level of HE4, carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3) and carbohydrate antigen 125 (CA125) were detected by ELISA assay in control and tumor patients. Further we compared the sensitivity and specificity of determining HE4, CA19-9, CA15-3, and CA125 for diagnosis of pancreatic adenocarcinoma and assessed the complementary diagnostic value of HE4, CA19-9, CA15-3 and CA125. Real time PCR showed significantly increased HE4 mRNA level in pancreatic adenocarcinoma compared with control. Result of IHC showed that HE4 significantly higher expressed in the human pancreatic carcinoma tissues than in both normal and adjacent non-tumorous pancreatic tissues, and the staining intensity is inversely correlated with the clinical stage. HE4 was highly expressed in early stage of pancreatic adenocarcinoma. Serum HE4 level is higher in cases with pancreatic adenocarcinoma than in the controls. Serum HE4 levels could research to a sensitivity of 45.83% and specificity of 93.75% when the Cutoff was set at 4.59 ng/mL. The Combined HE4 and CA19-9 increased the sensitivity to 83.33%; and interestingly, the combination of HE4 with CA15-3 led to the most powerful sensitivity of 87.5%. Combined with CA19-9 and CA15-3, HE4 could be a potential biomarker to improve the diagnostic power for pancreatic adenocarcinoma. PMID:25642754

    This clinical case report describes the diagnosis and treatment of an external invasive cervical resorption. A 17-year-old female patient had a confirmed diagnosis of invasive cervical resorption class 4 by cone beam computerized tomography. Although, there was no communication with the root canal, the invasive resorption process was extending into the cervical and middle third of the root. The treatment of the cervical resorption of the lateral incisor interrupted the resorptive process and restored the damaged root surface and the dental functions without any esthetic sequelae. Both the radiographic examination and computed tomography are imperative to reveal the extent of the defect in the differential diagnosis. PMID:22144822

    Fertility can be preserved after conservative cervical surgery. We report on a 29-year-old woman who was obese, para 0, and diagnosed with cervical insufficiency at the first trimester of current pregnancy due to a previous trachelectomy. She underwent laparoscopic transabdominal cervical cerclage (LTCC) for cervical cancer. The surgery was successful and she was discharged two days later. The patient underwent a caesarean section at 38 weeks of gestation. Laparoscopic surgery is a minimally invasive approach associated with less pain and faster recovery, feasible even in obese women.

    Cervical cancer is a major disease with high mortality. All cervical cancers are caused by infection with human papillomaviruses (HPV). Although preventive vaccines for cervical cancer are successful, treatment of cervical cancer is far less satisfactory because of multidrug resistance and side effects. In this review, we summarize the recent application of nanotechnology to the diagnosis and treatment of cervical cancer as well as the development of HPV vaccines. Early detection of cervical cancer enables tumours to be efficiently removed by surgical procedures, leading to increased survival rate. The current method of detecting cervical cancer by Pap smear can only achieve 50% sensitivity, whereas nanotechnology has been used to detect HPVs with greatly improved sensitivity. In cervical cancer treatment, nanotechnology has been used for the delivery of anticancer drugs to increase treatment efficacy and decrease side effects. Nanodelivery of HPV preventive and therapeutic vaccines has also been investigated to increase vaccine efficacy. Overall, these developments suggest that nanoparticle-based vaccine may become the most effective way to prevent and treat cervical cancer, assisted or combined with some other nanotechnology-based therapy.

    Pancreatic ductal adenocarcinoma (PDAC) stands as the poorest prognostic tumor of the digestive tract, with a 5-year survival rate of less than 5%. Therapeutic options for unresectable PDAC are extremely limited and there is a pressing need for expanded therapeutic approaches to improve current options available with gemcitabine-based regimens. With PDAC displaying one of the most prominent desmoplastic stromal reactions of all carcinomas, recent research has focused on the microenvironment surrounding PDAC cells. Secreted protein acid and rich in cysteine (SPARC), which is overexpressed in PDAC, may display tumor suppressor functions in several cancers (e.g., in colorectal, ovarian, prostate cancers, and acute myelogenous leukemia) but also appears to be overexpressed in other tumor types (e.g., breast cancer, melanoma, and glioblastoma). The apparent contradictory functions of SPARC may yield inhibition of angiogenesis via inhibition of vascular endothelial growth factor, while promoting epithelial-to-mesenchymal transition and invasion through matrix metalloprotease expression. This feature is of particular interest in PDAC where SPARC overexpression in the stroma stands along with inhibition of angiogenesis and promotion of cancer cell invasion and metastasis. Several therapeutic strategies to deplete stromal tissue have been developed. In this review, we focused on key preclinical and clinical data describing the role of SPARC in PDAC biology, the properties, and mechanisms of delivery of drugs that interact with SPARC and discuss the proof-of-concept clinical trials using nab-paclitaxel.

    Pancreatic cancer is a devastating disease. At time of diagnosis the disease is usually advanced and only a minority of patients are eligible for surgical resection. The overall 5-year survival is 6%. However, survival of patients with early stage pancreatic cancer is significantly better. To improve the prognosis of patients with pancreatic cancer, it is essential to diagnose and treat pancreatic cancer in the earliest stage. Prevention of pancreatic cancer by treating noninvasive precursor lesions just before they invade tissues can potentially lead to even better outcomes. Pancreatic carcinogenesis results from a stepwise progression in which accumulating genetic alterations drive neoplastic progression in well-defined precursor lesions, ultimately giving rise to an invasive adenocarcinoma. A thorough understanding of the genetic changes that drive pancreatic carcinogenesis can lead to identification of biomarkers for early detection and targets for therapy. Recent next-generation sequencing (NGS) studies have shed new light on our understanding of the natural history of pancreatic cancer and the precursor lesions that give rise to these cancers. Importantly, there is a significant window of opportunity for early detection and treatment between the first genetic alteration in a cell in the pancreas and development of full-blown pancreatic cancer. The current views on the pathology and genetics of pancreatic carcinogenesis that evolved from studies of pancreatic cancer and its precursor lesions are discussed in this review. PMID:26261723

    Endometriosis generally occurs in the ovary. Intestinal endometriosis is rare. About 1 % of all endometriosis cases become malignant. Malignant transformation of small intestinal endometriosis is very rare. A 55-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy and omentectomy for endometriosis 7 years ago presented to her primary care doctor with melena. A tumor was detected in the right lower abdomen by ultrasonography. The doctor referred her to our hospital. Computed tomography demonstrated a lobulated tumor ventral to the right common iliac vessels. Magnetic resonance imaging demonstrated that the tumor had heterogeneous intensity on T2-weighted images. Several small cysts with high intensity were observed caudal to the tumor on T2-weighted images. We performed partial small intestinal resection for the lesion. The tumor was diagnosed as endometrioid adenocarcinoma of the small intestine. She has been relapse-free for 5 years after surgery. Only three cases of malignant transformation of small intestinal endometriosis have been reported previously. It is very rare for long-term survival to be obtained with surgery alone, as in our case. This case report highlights the imaging findings for malignant transformation of intestinal endometriosis. PMID:27624553

    Hepatoid adenocarcinoma (HAC) is a rare neoplasm with aberrant hepatocellular differentiation. HAC occurs in extrahepatic organs such as the gastrointestinal tract, testes, ovaries, and lungs and frequently produces alpha-fetoprotein. A 69-year-old patient was diagnosed clinically with T2aN0M0, stage IB, non-small cell lung carcinoma. Because the tumor showed tight adhesion to the chest wall, we performed left upper lobectomy, combined resection of the 3rd and 4th ribs, and lymph node dissection. Pathological examination confirmed the diagnosis of HAC of the lung (pathological T2aN0M0, stage IB), and four courses of cisplatin and gemcitabine were administered as adjuvant chemotherapy. Genetic analysis of the epidermal growth factor receptor showed wild type. Preoperative serum alpha-fetoprotein level, a useful marker of disease progression, was elevated to 4497 ng/ml, decreasing within the normal range by about 3 months postoperatively. The patient remains alive without recurrence as of 51 months after surgery. PMID:26943677

    Systemic treatment of metastatic pancreatic adenocarcinoma achieves only modest benefits, with evidence indicating a survival advantage with 5-fluorouracil (5-FU) over best supportive care alone, and further advantage of single-agent gemcitabine over 5-FU. There are very few regimens better than single-agent gemcitabine despite multiple trials of cytotoxic and targeted agents. The addition of a platinum agent has improved response rate but not survival. The addition of erlotinib has improved survival but only by a small margin. The use of gemcitabine in multidrug regimens containing one or more of: a platinum agent; fluoropyrimidine; anthracycline; and taxane has demonstrated advantages in response rate, progression-free survival and, in one randomized study, overall survival. After gemcitabine failure, second-line therapy with oxaliplatin and 5-FU provides a further survival advantage. Further advances depend upon the current and future clinical trials investigating enhanced delivery of current agents, new agents and novel modalities, improved supportive care, and treatment more tailored to the individual patient and tumour.

    With 5-year survival rates remaining constant at 6% and rising incidences associated with an epidemic in obesity and metabolic syndrome, pancreatic ductal adenocarcinoma (PDAC) is on track to become the second most common cause of cancer-related deaths by 2030. The high mortality rate of PDAC stems primarily from the lack of early diagnosis and ineffective treatment for advanced tumors. During the past decade, the comprehensive atlas of genomic alterations, the prominence of specific pathways, the preclinical validation of such emerging targets, sophisticated preclinical model systems, and the molecular classification of PDAC into specific disease subtypes have all converged to illuminate drug discovery programs with clearer clinical path hypotheses. A deeper understanding of cancer cell biology, particularly altered cancer cell metabolism and impaired DNA repair processes, is providing novel therapeutic strategies that show strong preclinical activity. Elucidation of tumor biology principles, most notably a deeper understanding of the complexity of immune regulation in the tumor microenvironment, has provided an exciting framework to reawaken the immune system to attack PDAC cancer cells. While the long road of translation lies ahead, the path to meaningful clinical progress has never been clearer to improve PDAC patient survival. PMID:26883357

    Pancreatic ductal adenocarcinoma (PDAC) accounts for over 90% of all pancreatic cancer. Nanoparticles (NPs) offer new opportunities for image-guided therapy owing to the unique physicochemical properties of the nanoscale effect and the multifunctional capabilities of NPs. However, major obstacles exist for NP-mediated cancer theranostics, especially in PDAC. The hypovascular nature of PDAC may impede the deposition of NPs into the tumor after systemic administration, and most NPs localize predominantly in the mononuclear phagocytic system, leading to a relatively poor tumor-to-surrounding-organ uptake ratio. Image guidance combined with minimally invasive interventional procedures may help circumvent these barriers to poor drug delivery of NPs in PDAC. Interventional treatments allow regional drug delivery, targeted vascular embolization, direct tumor ablation, and the possibility of disrupting the stromal barrier of PDAC. Interventional treatments also have potentially fewer complications, faster recovery, and lower cost compared with conventional therapies. This work is an overview of current image-guided interventional cancer nanotheranostics with specific attention given to their applications for the management of PDAC. PMID:27375787

    Gastric cancer is a leading cause of cancer deaths, but analysis of its molecular and clinical characteristics has been complicated by histological and aetiological heterogeneity. Here we describe a comprehensive molecular evaluation of 295 primary gastric adenocarcinomas as part of The Cancer Genome Atlas (TCGA) project. We propose a molecular classification dividing gastric cancer into four subtypes: tumours positive for Epstein–Barr virus, which display recurrent PIK3CA mutations, extreme DNA hypermethylation, and amplification of JAK2, CD274 (also known as PD-L1) and PDCD1LG2 (also knownasPD-L2); microsatellite unstable tumours, which show elevated mutation rates, including mutations of genes encoding targetable oncogenic signalling proteins; genomically stable tumours, which are enriched for the diffuse histological variant and mutations of RHOA or fusions involving RHO-family GTPase-activating proteins; and tumours with chromosomal instability, which show marked aneuploidy and focal amplification of receptor tyrosine kinases. Identification of these subtypes provides a roadmap for patient stratification and trials of targeted therapies. PMID:25079317

    2016-03-01

    The incidence of esophageal adenocarcinoma (EAC) has increased rapidly during the past 4 decades in many Western populations, including North America and Europe. The established etiological factors for EAC include gastroesophageal reflux and obesity, Helicobacter pylori infection, tobacco smoking, and consumption of fruit and vegetables. There is a marked male predominance of EAC with a male-to-female ratio in incidence of up to 9:1. This review evaluates the available literature on the reasons for the male predominance, particularly an update on epidemiologic evidence from human studies during the past decade. The striking sex difference does not seem to be explained by established risk factors, given that the prevalence of the etiological factors and the strengths of associations between these factors and EAC risk are similar between the sexes. Sex hormonal factors may play a role in the development of EAC; estrogenic exposures may prevent such development, whereas androgens might increase the risk of EAC. However, continuing research efforts are still needed to fully understand the reasons for the male predominance of EAC. PMID:26484704

    Hepatoid adenocarcinoma is a rare extrahepatic tumor, which shows morphological and immunohistochemical similarities to hepatocellular carcinoma (HCC). Hence, hepatoid adenocarcinoma can cause diagnostic confusion with HCC. Arginase-1 immunostain has been recently shown to be an excellent marker of normal hepatocytes and is a sensitive and specific marker for HCC. However, the expression of Arginase-1 in hepatoid adenocarcinoma has not been evaluated in detail. Eight cases of hepatoid adenocarcinoma were immunostained with Arginase-1, Hepar-1, Glypican-3, CK7, CK20, CK19, polyclonal carcinoembryonic antigen, ɑ-fetoprotein, CDX2, and TTF-1. Albumin in situ hybridization was performed in 4 cases. All 8 cases were positive for Hepar-1. Arginase-1 was positive in 5 (62.5%) of 8 cases; 2 of these cases showed diffuse staining, while 3 showed patchy staining. Glypican-3, CK7 and ɑ-fetoprotein were each positive in 4 (50%) of 8 cases. CK19 was positive in 3 (37.5%) of 8 cases. polyclonal carcinoembryonic antigen showed canalicular staining in 3 (37.5%) of 8 cases and albumin in situ hybridization was positive in 3 (75%) of 4 cases. CDX2 was positive in 2 (25%) of 8 cases, both arising from the stomach. CK20 was positive in 1 (12.5%) of 8 case while TTF-1 was negative in all cases. Hepatoid adenocarcinoma has a similar immunostaining profile as HCC. Arginase-1 expression is common (62.5%) in hepatoid adenocarcinoma and hence it is not useful in distinguishing HCC from hepatoid adenocarcinoma. PMID:27137985

    As a result of technological advances during the past two decades, surgeons now use minimally invasive surgery (MIS) approaches to pancreatic resection more frequently, yet the role of these approaches for pancreatic ductal adenocarcinoma resections remains uncertain, given the aggressive nature of this malignancy. Although there are no controlled trials comparing MIS technique to open surgical technique, laparoscopic distal pancreatectomy for pancreatic adenocarcinoma is performed with increasing frequency. Data from retrospective studies suggest that perioperative complication profiles between open and laparoscopic distal pancreatectomy are similar, with perhaps lower blood loss and fewer wound infections in the MIS group. Concerning oncologic outcomes, there appear to be no differences in the rate of achieving negative margins or in the number of lymph nodes (LNs) resected when compared to open surgery. There are limited recurrence and survival data on laparoscopic compared to open distal pancreatectomy for pancreatic adenocarcinoma, but in the few studies that assess long term outcomes, recurrence rates and survival outcomes appear similar. Recent studies show that though laparoscopic distal pancreatectomy entails a greater operative cost, the associated shorter length of hospital stay leads to decreased overall cost compared to open procedures. Multiple new technologies are emerging to improve resection of pancreatic cancer. Robotic pancreatectomy is feasible, but there are limited data on robotic resection of pancreatic adenocarcinoma, and outcomes appear similar to laparoscopic approaches. Additionally fluorescence-guided surgery represents a new technology on the horizon that could improve oncologic outcomes after resection of pancreatic adenocarcinoma, though published data thus far are limited to animal models. Overall, MIS distal pancreatectomy appears to be a safe and reasonable approach to treating selected patients with pancreatic ductal

    The key insight that sparked Darwin's theory of descent with modification was that he compared and contrasted differences between living and extinct species across time and space. He likely arrived on this theory in large part through his culinary experiences, set against the background of the rugged Patagonian landscape of Southern Argentina. We feel that further integration of research into gastric and esophageal adenocarcinoma may benefit both fields and similarly lead to a coherent understanding of cancer progression in the upper gastrointestinal tract across time and space. Although the environmental trigger differs between carcinogenesis of the stomach and distal esophagus, there remain many important lessons to be learned from comparing precursor stages, such as intestinal metaplasia, across anatomic borders. This analysis will absolutely require detailed sampling within and between these related species, but most importantly we need higher resolution clinical phenotyping to relate genomic differences to drivers of morphologic evolution. In the end, this may provide us with a new phylogeny showing key differences between esophageal and gastric adenocarcinoma. PMID:27573764

    OBJECTIVE: To conduct a failure analysis of cervical cancer screening among women with invasive cervical cancer in Alberta. DESIGN: Descriptive study. Review of demographic, staging and treatment information from cancer registry records; generation of documented screening history from Alberta Health billing records and self-reported history from subjects who agreed to be interviewed; and comparison of findings in initial cytology reports with those from subsequent review by at least 2 pathologists of all cytology slides for each patient for the 5 years before diagnosis. Cases were assigned to 1 of 6 categories of identified screening failure. SETTING: Alberta. SUBJECTS: All women with diagnosis of invasive cervical cancer reported to a population-based provincial cancer registry from January 1990 to December 1991. OUTCOME MEASURES: Demographic, staging and treatment information; documented and self-reported screening histories; correlation of test results in initial cytology report with those generated from slide review; category of identified screening failure. RESULTS: Of the 246 women identified with invasive cancer of the cervix, 37 (15.0%) had stage IA disease; 195 (79.3%) had squamous-cell carcinoma, and 35 (14.2%) had adenocarcinoma. According to the categories of screening failure, 74 women (30.1%) had never been screened, 38 (15.4% had not been screened within 3 years before diagnosis, 42 (17.1%) had had a false-negative cytology result, and 20 (8.1%) had been managed outside of conventional protocols. Of the 23 women (9.3%) who had been screened appropriately and had true-negative results, 19 had smears that were considered technically limited. It was not possible to classify 49 (19.9%) of the cases. Agreement between the documented and the self-reported screening histories was exact for only 39 (36.1%) of the 108 women interviewed. CONCLUSIONS: Despite widespread use of opportunistic cervical screening, many women in Alberta are still not being screened

    We describe the clinicopathologic and immunohistochemical features of the first reported case of an ovarian low-grade serous carcinoma metastatic to the cervix mimicking a cervical primary. The patient, a 55-year-old woman, was found to have an abnormal cervix and an abnormal Pap smear during a preoperative workup for a rectocele repair. A subsequent cervical biopsy contained moderately differentiated adenocarcinoma and the patient underwent a cold knife conization. An infiltrating adenocarcinoma was found in the anterior cervical lip, the neoplasm reached the surface of the endocervical canal and was composed of mildly to moderately atypical, eosinophilic or amphophilic columnar cells arranged in glands and papillae. Mitotic figures were rare and no apoptotic bodies were seen. Psammoma bodies and intraglandular mucinous material were also noted. There was extensive vascular/lymphatic invasion. The tumor extended to all margins and was interpreted as a moderately differentiated (grade 2) adenocarcinoma of the uterine cervix with a linear spread of at least 1.4 cm and a depth of at least 0.6 cm (FIGO stage 1B1). The patient was treated with radiotherapy and cisplatin. Six months later, surveillance imaging studies showed that the patient's ovaries seemed to be enlarging. The patient underwent exploratory laparotomy, bilateral salpingo-oophorectomy, right pelvic lymph node sampling, omentectomy, peritoneal biopsies, and pelvic washings. The ovaries contained bilateral cystic tumors. There was gross tumor involving multiple peritoneal sites. Microscopic examination of the ovaries showed the typical features of low-grade serous carcinoma associated with a serous neoplasm of low malignant potential with a cribriform pattern. Metastatic low-grade serous carcinoma was detected in multiple peritoneal sites and in the pelvic washings. A consultation was obtained, with the consultant concurring that the tumors represented independent primaries. The patient received

    This is the protocol for a review and there is no abstract. The objectives are as follows: To evaluate the immunogenicity, clinical efficacy, and safety of prophylactic HPV vaccines in females. The assessment of clinical efficacy will address protection against HPV infection (for homologous and heterologous HPV types), against re-infection, against cervical cancer and its precursors (high-grade CIN (grade 2 or grade 3), adenocarcinoma in situ) in women previously not exposed to HPV infection (negative at enrolment for both HPV DNA and antibodies against the vaccine HPV types). We will assess clinical effectiveness by evaluating outcomes in all women, irrespective of the HPV DNA or serology status at enrolment. Evaluation by fine age and time since sexual debut categories is also planned. PMID:25267916

    K-ras codon 12 point mutations mRb and p53 gene deletions were examined in tissues from 120 normal lungs and lung adenocarcinomas that were Formalin-treated and paraffin-embedded 25 years ago. The results showed that 12 of 60 (20%) lung adenocarcinomas had mRb deletions. All lung adenocarcinomas that were initially found bearing deleted mRb had p53 deletions (15 of 15; 100%). A significantly higher mutation frequency for K-ras codon 12 point mutations was also found in the lung adenocarcinomas from mice exposed to 24 once-weekly neutron irradiation (10 of 10; 100%) compared with those exposed to 24 or 60 once-weekly {gamma}-ray doses (5 of 10; 50%). The data suggested that p53 and K-ras gene alterations were two contributory factors responsible for the increased incidence of lung adenocarcinoma in B6CF{sub 1} male mice exposed to protracted neutron radiation.

    From the available literature, it is unclear what proportion of pancreatic adenocarcinomas express estrogen receptors (ERα, ERβ), progesterone receptors (PR), and androgen receptors (AR), and if any of these markers have prognostic significance. We aimed to assess (1) the expression and (2) the correlation of the aforementioned markers with clinicopathological parameters and prognosis in patients with pancreatic adenocarcinoma. During a five-year period, 60 patients with pancreatic ductal adenocarcinoma underwent surgical resection at a single institution. Immunohistochemical stains of the studied markers were quantified by Image analysis system. ERα expression was positively associated with PR expression. Moreover, ERβ was inversely associated with the presence of metastases, whereas no significant associations implicated AR. As far as the prognostic significance of the studied receptors is concerned, higher ERα expression correlated with poorer survival at the univariate analysis, but the finding dissipated at the multivariate approach. No significant associations with overall survival were noted regarding the other receptors. The role of sex hormone receptors in the survival from pancreatic adenocarcinoma seems rather limited. Further prospective studies assessing those receptors should ideally be designed in order to confirm our results and possibly outline additional correlations between other steroid receptors and features of pancreatic adenocarcinoma.

    Background The detection rate of synchronous multiple lung adenocarcinomas (SMLA), which display multiple ground glass opacity nodules in the peripheral lung, is increasing due to advances in high resolution computed tomography. The backgrounds of multicentric development of adenocarcinoma are unknown. In this study, we quantitated estrogen concentration in the peripheral lungs of postmenopausal female patients with SMLA. Methods The tissue concentration of estrogens (estrone [E1] and estdadiol [E2]) in the noncancerous peripheral lung were measured with liquid chromatography/electrospray tandem mass spectrometry in postmenopausal female patients with lung adenocarcinoma. The expression levels of CYP19A1 in the normal lung were also quantitated with real-time PCR. Thirty patients with SMLA and 79 cases of control patients with single lung adenocarcinoma were analyzed. Results The concentrations of E1 and E2 in the noncancerous tissue were significantly higher in SMLA cases than control cases (P = 0.004 and P = 0.02, respectively). The minor allele (A) of single nucleotide polymorphism rs3764221 were significantly associated with higher concentration of E1 and E2 (P = 0.002 and P = 0.01, respectively) and higher CYP19A1 mRNA expression (P = 0.03). Conclusion The tissue estrogen concentration of peripheral lung was significantly higher in SMLA than control cases. The high concentration of estrogen may be one of the causes of multicentric development of peripheral lung adenocarcinomas. PMID:27526096

    SUMMARY Lung adenocarcinoma, the most common subtype of non-small cell lung cancer, is responsible for over 500,000 deaths per year worldwide. Here, we report exome and genome sequences of 183 lung adenocarcinoma tumor/normal DNA pairs. These analyses revealed a mean exonic somatic mutation rate of 12.0 events/megabase and identified the majority of genes previously reported as significantly mutated in lung adenocarcinoma. In addition, we identified statistically recurrent somatic mutations in the splicing factor gene U2AF1 and truncating mutations affecting RBM10 and ARID1A. Analysis of nucleotide context-specific mutation signatures grouped the sample set into distinct clusters that correlated with smoking history and alterations of reported lung adenocarcinoma genes. Whole genome sequence analysis revealed frequent structural re-arrangements, including in-frame exonic alterations within EGFR and SIK2 kinases. The candidate genes identified in this study are attractive targets for biological characterization and therapeutic targeting of lung adenocarcinoma. PMID:22980975

    ATP-binding cassette transporter E1 (ABCE1), also known as RLI (RNase L inhibitor), is a new type of endoribonuclease inhibitor, which can specifically bind to RNase L and abolish its effect. ABCE1 binds to eIF2α and eIF5 to form a pre-translation initiation complex, suggesting its crucial role in cell growth, development and certain pathological processes. To probe the role of ABCE1 in the development and progress of human lung adenocarcinoma, we first detected the changes of its mRNA and protein expression in tissues, and found a high expression level of ABCE1 in human lung adenocarcinoma tissues and metastatic lymph nodes, which was also correlated with clinical stages. Moreover, human lung adenocarcinoma A549 cells were infected with lentiviral vectors containing ABCE1-specific shRNA, and resulted in significant inhibition of cell growth. Using microarray assay, a number of differentially expressed genes were found after ABCE1 suppression. Our results demonstrated the potential role of ABCE1 in human lung adenocarcinoma, which may provide some molecular basis for the mechanisms of development and progress of human lung adenocarcinoma, and help to find new pharmacological targets.

    Pathological diagnosis is influenced by subjective factors such as the individual experience and knowledge of doctors. Therefore, it may be interpreted in different ways for the same symptoms. The appearance of digital pathology has created good foundation for objective diagnoses based on quantitative feature analysis. Recently, numerous studies are being done to develop automated diagnosis based on the digital pathology. But there are as of yet no general automated methods for pathological diagnosis due to its specific nature. Therefore, specific methods according to a type of disease and a lesion could be designed. This study proposes quantitative features that are designed to diagnose pancreatic ductal adenocarcinomas. In the diagnosis of pancreatic ductal adenocarcinomas, the region of interest is a duct that consists of lumen and epithelium. Therefore, we first segment the lumen and epithelial nuclei from a tissue image. Then, we extract the specific features to diagnose the pancreatic ductal adenocarcinoma from the segmented objects. The experiment evaluated the classification performance of the SVM learned by the proposed features. The results showed an accuracy of 94.38% in the experiment distinguishing between pancreatic ductal adenocarcinomas and normal tissue and a classification accuracy of 77.03% distinguishing between the stages of pancreatic ductal adenocarcinomas.

    In recent decades there has been a dramatic rise in the incidence of esophageal adenocarcinoma (EAC) in the developed world. Over approximately the same period there has also been an increase in the prevalence of obesity. Obesity, especially visceral obesity, is an important independent risk factor for the development of gastro-esophageal reflux disease, Barrett’s esophagus and EAC. Although the simplest explanation is that this mediated by the mechanical effects of abdominal obesity promoting gastro-esophageal reflux, the epidemiological data suggest that the EAC-promoting effects are independent of reflux. Several, not mutually exclusive, mechanisms have been implicated, which may have different effects at various points along the reflux-Barrett’s-cancer pathway. These mechanisms include a reduction in the prevalence of Helicobacter pylori infection enhancing gastric acidity and possibly appetite by increasing gastric ghrelin secretion, induction of both low-grade systemic inflammation by factors secreted by adipose tissue and the metabolic syndrome with insulin-resistance. Obesity is associated with enhanced secretion of leptin and decreased secretion of adiponectin from adipose tissue and both increased leptin and decreased adiponectin have been shown to be independent risk factors for progression to EAC. Leptin and adiponectin have a set of mutually antagonistic actions on Barrett’s cells which appear to influence the progression of malignant behaviour. At present no drugs are of proven benefit to prevent obesity associated EAC. Roux-en-Y reconstruction is the preferred bariatric surgical option for weight loss in patients with reflux. Statins and aspirin may have chemopreventative effects and are indicated for their circulatory benefits. PMID:25400997

    Pancreatic ductal adenocarcinoma (PDAC) is an incurable lethal disease whose incidence rate is growing. There is no effective screening for detection of early stage tumors and, in most cases, PDAC is diagnosed at advanced disease stages, when radical pancreatic resection is not possible. The aggressive nature of pancreatic tumor cells lies in the complex genetic mechanisms behind their uncontrolled capability to grow and metastasize, which involve essential adaptive changes in cellular metabolism, signaling, adhesion and immunoediting. In addition, PDAC cells promote a dense functional stroma that facilitates tumor resistance to chemotherapy and radiation. During the last two decades, gemcitabine has been the reference for the systemic treatment of PDAC. However, recently, a regimen combining fluorouracil, irinotecan, oxaliplatin, and leucovorin (FOLFIRINOX) and another combining albumin-bound paclitaxel with gemcitabine have shown clear therapeutic advantage in advanced PDAC, with survival outcomes of 11.3 and 8.5 mo on phase III trials, respectively, over single-agent gemcitabine. With the pending issue of their higher toxicities, these regimens set the reference for ongoing and future clinical studies in advanced PDAC. In addition, the efficacy of oral fluoropyrimidine (S-1) has been well documented in Asiatic PDAC patients. The development of therapeutic approaches other than cytotoxic drugs has proven difficult in the past, with only one drug (erlotinib) approved to date. Besides, a number of agents targeting signaling pathways in tumor or stroma cells are being investigated. Likewise, immunotherapies that target PDAC in various ways are the subject of a number of clinical trials. The search for reliable biomarkers with diagnostic and prognostic value using genomics and mass spectrometry methods may facilitate monitoring and refinement of therapies. This review focuses on current understanding of the pathogenesis of PDAC and the latest developments in the

    Instability of tandem repeat sequences (microsatellites) has been reported to play a major etiologic role in familial colon cancer, as well as a potential role in the carcinogenesis of other sporadic neoplasms. These replication errors are the result of faulty DNA excision/repair function controlled at the gene level. In order to examine this phenomenon in prostate cancer, we screened 40 tumors with di-, tri- and tetranucleotide markers spanning eleven chromosomal loci. Microsatellite instability was observed overall in 3 of the 40 cases (7.5%). All changes were identified solely in tetranucleotide sequences (3 of 11 total markers analyzed). One tumor demonstrated repeat length expansions at two loci, while the other tumors did so at a single locus. Both Type 1 (>4 base pairs) and Type II (4 base pairs) mutations were identified. One of these cases also included metastatic nodal disease. Analysis of the metastatic tumor tissue revealed allelic patterns identical to the normal tissue control. A secondary screening of the mutated tumors demonstrated no repeat length alterations in 16 additional markers. A CAG repeat in the androgen receptor (AR) gene was also studied and demonstrated that 3 of 40 (7.5%) tumors contained mutations within this repeat. We concluded that microsatellite instability is uncommon in prostate adenocarcinoma appearing to occur more often in tetranucleotide repeat sequences and in an AR gene repeat. Additionally, these findings suggest that dysfunctional DNA excision/repair mechanisms, as evidenced by the low frequency of replication errors, are unlikely to play a major role in the natural history of prostate cancer.

  16. Gemcitabine resistance in pancreatic ductal adenocarcinoma.

    PubMed

    2015-11-01

    Pancreatic ductal adenocarcinoma (PDA) ranks fourth among cancer related deaths. The disappointing 5-year survival rate of below 5% stems from drug resistance to all known therapies, as well as from disease presentation at a late stage when PDA is already metastatic. Gemcitabine has been the cornerstone of PDA treatment in all stages of the disease for the last two decades, but gemcitabine resistance develops within weeks of chemotherapy initiation. From a mechanistic perspective, gemcitabine resistance may result from alterations in drug metabolism until the point that the cytidine analog is incorporated into the DNA, or from mitigation of gemcitabine-induced apoptosis. Both of these drug resistance modalities can be either intrinsic to the cancer cell, or influenced by the cancer microenvironment. Mechanisms of intrinsic gemcitabine resistance are difficult to tackle, as many of the genes that drive the carcinogenic process itself also interfere with gemcitabine-induced apoptosis. In this regard, recent understanding of the involvement of microRNAs in gemcitabine resistance may offer new opportunities to overcome intrinsic gemcitabine resistance. The characteristically fibrotic and immune infiltrated stroma of PDA that accompanies tumor inception and expansion is a lush ground for treatments aimed at targeting tumor microenvironment-mediated drug resistance. In the last couple of years, drugs interfering with tumor microenvironment have matured to clinical trials. Although drugs inducing 'stromal depletion' have yet failed to improve survival, they have greatly increased our understanding of tumor microenvironment-mediated drug resistance. In this review we summarize the current knowledge on intrinsic and environment-mediated gemcitabine resistance, and discuss the impact of these pathways on patient screening, and on future treatments aimed to potentiate gemcitabine activity.

    An 11-year-old intact female Doberman Pinscher was presented with the complaint of non-ambulatory tetraparesis. Clinical and neurological examination revealed a caudal cervical spinal cord disfunction (C6-T2 spinal cord segments). Magnetic resonance imaging and computed tomographic (CT) findings of the cervical spine were consistent with caudal cervical spondylomyelopathy (CSM). During the diagnostic work-up for the cervical spine, bilateral bone anomalies involving the seventh cervical vertebra and the first ribs were found on radiographs and CT examination. The rib anomalies found in this dog appear similar to cervical ribs widely described in human medicine. In people, cervical ribs are associated with a high rate of stillbirth, early childhood cancer, and can cause the thoracic outlet syndrome, characterized by neurovascular compression at level of superior aperture of the chest. In dogs, only some sporadic anatomopathological descriptions of cervical ribs exist. In this report the radiographic and CT findings of these particular vertebral and rib anomalies along with their relationships with adjacent vasculature and musculature are shown intravitam in a dog. Specific radiographic and CT findings described in this report may help in reaching a presumptive diagnosis of this anomaly. Finally, their clinical and evolutionary significance are discussed.

    Cervical spine injuries are extremely common and range from relatively minor injuries, such as cervical muscle strains, to severe, life-threatening cervical fractures with spinal cord injuries. Although cervical spine injuries are most common in athletes who participate in contact and collision sports, such as American football and rugby, they also have been reported in athletes who participate in noncontact sports, such as baseball, gymnastics, and diving. Cervical spine injuries in athletes are not necessarily the result of substantial spine trauma; some athletes have chronic conditions, such as congenital stenosis, that increase their risk for a serious cervical spine injury after even minor trauma. Therefore, physicians who cover athletic events must have a thorough knowledge of cervical spine injures and the most appropriate ways in which they should be managed. Although cervical spine injuries can be career-ending injuries, athletes often are able to return to play after appropriate treatment if the potential for substantial re-injury is minimized.

    The International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society and 2015 World Health Organization classifications of lung adenocarcinoma recommend designating tumors showing entirely lepidic growth as adenocarcinoma in situ (AIS) and lepidic tumors with invasion less than or equal to 5 mm as minimally invasive adenocarcinoma (MIA), both of which have superior outcome to conventional invasive adenocarcinoma (IA). Data on interobserver variability within this classification are limited, and further validation of the superior survival of AIS and MIA is needed. A total of 296 surgically excised pulmonary adenocarcinomas were reviewed from 254 patients (1997-2009). Slides were independently reviewed by 2 pulmonary pathologists who categorized tumors as AIS, MIA, or IA. Of 296 nodules, 244 (82.4%) were agreed upon by both observers: 10 AIS, 61 MIA, and 173 IA (κ = 0.63, good agreement). In 6 cases (2%), there was disagreement between AIS and MIA; in 45 cases (15%), there was disagreement between MIA and IA; and in 1 case, there was disagreement between AIS and IA. Overall survival was significantly different among categories as determined by both observers. Cases with disagreement between MIA and IA had similar survival to agreed MIA. Disease-specific 10-year survival was 100% for AIS (both observers) and 97.3% and 97.6% for MIA, although this did not reach statistical significance compared to IA for either observer. Good agreement was present between observers when classifying tumors as AIS, MIA, and IA. Significant differences in overall survival were present between the 3 groups for both observers, and interobserver variability was evident. Patients with AIS and MIA experienced excellent DSS.

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    Cervical myelopathy is a well-described clinical syndrome that may evolve from a combination of etiological mechanisms. It is traditionally classified by cervical spinal cord and/or nerve root compression which varies in severity and number of levels involved. The vast array of clinical manifestations of cervical myelopathy cannot fully be explained by the simple concept that a narrowed spinal canal causes compression of the cord, local tissue ischemia, injury and neurological impairment. Despite advances in surgical technology and treatment innovations, there are limited neuro-protective treatments for cervical myelopathy, which reflects an incomplete understanding of the pathophysiological processes involved in this disease. The aim of this review is to provide a comprehensive overview of the key pathophysiological processes at play in the development of cervical myelopathy. PMID:26807352

    Little is known about the incidence and risk of cervical intraepithelial neoplasia (CIN) grade 3, adenocarcinoma in situ and invasive cervical cancer (CIN3+) among migrants living with HIV in a European setting. We assessed the cumulative incidence (CuI) and hazard ratio (HR) of CIN2+ and CIN3+ in a cohort of women living with HIV (WLWH) (n = 893) identified from the Swedish national HIV register and HIV-negative women (n = 205,842) identified from the Swedish Population Register, matched on region of birth and age. Data was collected between 1993 and 2011 by linking our cohort with the Swedish National Cervical Screening Registry, collecting all cytological and histological results since 1993. The CuI of CIN3+ was 13.1% [95% confidence interval (CI) 8.9-17.2] for WLWH and 2.1% (95% CI 2.0-2.2) for HIV-negative after 18 years of follow-up. WLWH had more than eight times higher, age and region of birth matched, risk of CIN3+ than HIV-negative (HR 8.8: 95% CI 6.9-11.3). WLWH born in the East region, dominated by Thai women, had a two times higher risk of CIN3+ compared with WLWH born in Sweden (HR 2.47: 95% CI 1.2-5.0), which remained after adjusting for immunosuppression. Our results showed a substantially increased risk of CIN3+ among WLWH, which differed depending on birth region. Early HIV diagnosis and attendance to cervical cancer screening, with focus on migrants, is of crucial importance to minimize the incidence of cervical intraepithelial neoplasia. PMID:27177207

    Metastasis rarely occurs in the palatine tonsils. Among primary pulmonary carcinoma subtypes, small cell carcinoma more frequently metastasizes to this site. Herein, we present an exceedingly rare case of a small pulmonary adenocarcinoma that metastasized to the cervical lymph nodes and the right palatine tonsil in a 62-year-old man. In spite of the small size of the primary site, such extensive metastasis may have occurred because of the invasive micropapillary carcinoma pattern seen in the metastatic sites. The manner of metastasis to the palatine tonsil was considered retrograde lymphatic metastasis originating from carcinoma cells in the cervical lymph nodes. Furthermore, Pagetoid spread was observed at the palatine tonsil. Although there have been only a few cases showing retrograde lymphatic metastasis and Pagetoid spread at the metastatic site, we should be careful when speculating about the primary site based on such metastatic sites, especially when dealing with a biopsy sample exhibiting Pagetoid spread.

    2015-01-01

    Cervical disc replacement (CDR) has emerged as an alternative surgical option to cervical arthrodesis. With increasing numbers of patients and longer follow-ups, complications related to the device and/or aging spine are growing, leaving us with a new challenge in the management and surgical revision of CDR. The purpose of this study is to review the current literature regarding reoperations following CDR and to discuss about the approaches and solutions for the current and future potential complications associated with CDR. The published rates of reoperation (mean, 1.0%; range, 0%-3.1%), revision (mean, 0.2%; range, 0%-0.5%), and removal (mean, 1.2%; range, 0%-1.9%) following CDR are low and comparable to the published rates of reoperation (mean, 1.7%; range; 0%-3.4%), revision (mean, 1.5%; range, 0%-4.7%), and removal (mean, 2.0%; range, 0%-3.4%) following cervical arthrodesis. The surgical interventions following CDR range from the repositioning to explantation followed by fusion or the reimplantation to posterior foraminotomy or fusion. Strict patient selection, careful preoperative radiographic review and surgical planning, as well as surgical technique may reduce adverse events and the need for future intervention. Minimal literature and no guidelines exist for the approaches and techniques in revision and for the removal of implants following CDR. Adherence to strict indications and precise surgical technique may reduce the number of reoperations, revisions, and removals following CDR. Long-term follow-up studies are needed, assessing the implant survivorship and its effect on the revision and removal rates. PMID:26097667

  9. [Laminoplasty for cervical spondylotic myelopathy].

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    In 1962, a programme for early detection of cervical cancer was established at the national level. The programme is based on the collaboration of different groups of doctors and not on a system of sending out invitations to every woman. This programme was re-adapted twice according to the needs for assuring quality in a system of mainly liberal medicine. At present the programme is 'institutionalised' and is carried out according to the criteria defined in 1990. This includes a centralisation of the smear readings and handing out the material needed to take the smears. The contribution of the doctors is regulated by a system of bonuses given by the government and a reimbursement by the Health Fund. The annual cervical smear is free of charge for every woman. The participation of the women targeted by the programme (>15 years old) has increased by approximately 50% every decade from the early 1970s increasing from 10950 in 1972 to 70441 in 1999. Between 1980 and 1999, the number of women at risk taking part in the programme increased from 10.80 to 38.92%. The number of all the doctors taking smear samples increased from 68 to 105 and the number of gynaecologists increased from 19 (ratio Gyn/GP (gynaecologists/General Practitioners) of 28%) to 52 (ratio Gyn/GP of 50%). The mortality rate has decreased continuously from 6. 1/100000 in 1990 to 0.9/100000 in 1997. In conclusion, to be successful, a cervical cancer screening programme should be flexible enough to allow short-term adaptations to unexpected local situations and needs a highly motivated team of the different participants involved in the regional and national health policy.

    Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis. PMID:27217655

    2015-11-01

    Pancreatic cancer is one of the most lethal solid tumors. The prognosis of metastatic pancreatic adenocarcinoma remains dismal, with a median survival of less than 1 year, due in large part to the fact that pancreatic adenocarcinoma is notoriously refractory to chemotherapy. However, there recently have been significant improvements in outcomes for patients with pancreatic adenocarcinoma: ongoing trials have shown promise, and these may lead to still further progress. Here we review the current treatment paradigms for metastatic disease, focusing on ways to ameliorate symptoms and lengthen survival. We then summarize recent advances in our understanding of the molecular and cellular aspects of pancreatic cancer. Finally, we outline new approaches currently under development for the treatment of metastatic disease, arising from our improved understanding of the genetic and nongenetic alterations within pancreatic cancer cells-and of interactions between cancer cells, the tumor microenvironment, and the immune system.

    Primary carcinoma of ureter is an uncommon malignancy. Of which, mostly are transitional cell carcinomas followed by squamous cell carcinomas and adenocarcinomas being the rarest histopathology encountered. We report a case of adenocarcinoma ureter in a middle-aged male along with its clinical scenario. A 62-year-old male, presented with complaints of lower urinary tract symptoms. Computerized tomography urogram showed a soft tissue lesion at the right ureterovesical junction. Cystoscopic biopsy reported villous adenoma. Diethylene triamine pentaacetic acid scan reported nonfunctioning right kidney. He underwent laparoscopic right nephroureterectomy, and histopathology reported adenocarcinoma of the right lower third of ureter, with positive distal and close radial margins. The patient received external beam radiation to the postoperative bed and lymph nodes, and he is disease-free till date. PMID:27453661

    2016-02-01

    Hepatoid adenocarcinoma (HAC) is a rare but important type of extrahepatic tumor that has a morphologic similarity to hepatocellular carcinoma, with production of α-fetoprotein in high amounts and a poor prognosis. Stomach is one of the organs in which HAC has been most commonly identified. We report a case of an old man with a polypoid mass in the prepyloric region. The microscopical aspects were suggestive for an undifferentiated adenocarcinoma, but the positive immunohistochemical staining for α-fetoprotein, α-1-antitrypsin, α-1-antichymotrypsin, and Hep Par1 were crucial for the final diagnosis of hepatoid adenocarcinoma of the stomach. Because of the poor prognosis for this type of tumor, correct and early-stage diagnosis of HAC is essential and long-term follow-up is required. PMID:26844385

    Cloyd, Jordan M; George, Elizabeth; Visser, Brendan C

    2016-01-01

    Duodenal adenocarcinoma is a rare but aggressive malignancy. Given its rarity, previous studies have traditionally combined duodenal adenocarcinoma (DA) with either other periampullary cancers or small bowel adenocarcinomas, limiting the available data to guide treatment decisions. Nevertheless, management primarily involves complete surgical resection when technically feasible. Surgery may require pancreaticoduodenectomy or segmental duodenal resection; either are acceptable options as long as negative margins are achievable and an adequate lymphadenectomy can be performed. Adjuvant chemotherapy and radiation are important components of multi-modality treatment for patients at high risk of recurrence. Further research would benefit from multi-institutional trials that do not combine DA with other periampullary or small bowel malignancies. The purpose of this article is to perform a comprehensive review of DA with special focus on the surgical management and principles. PMID:27022448

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Second fatal mesenchymal and epithelial primaries have been described in 8.5% of patients with bilateral retinoblastomas previously treated with radiotherapy; however, papillary adenocarcinoma arising within the paranasal sinuses has not been reported. Aggressive treatment including partial maxillectomy, radical pansinusectomy, radical neck dissection followed by regional radiotherapy and systemic chemotherapy failed to prevent the development of fatal hepatic metastases. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy.

  18. The distinctive nature of adenocarcinoma of the lung

    In recent years, many personalized treatments have been developed for NSCLC (non-small-cell lung cancer) patients. Among these, gefitinib, erlotinib, and afatinib are selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors for patients with EGFR gene mutations, while crizotinib and ceritinib are two new tyrosine kinase inhibitors directed against the echinoderm microtubule-like protein 4-anaplastic lymphoma kinase translocation. The possibility of these new molecules being used to treat patients without adenocarcinoma histology is notably small. For example, EGFR mutations and anaplastic lymphoma kinase fusion gene rearrangement are rare in patients with squamous cell carcinoma (generally <1%). Additionally, the benefit of targeted treatment approaches in patients with small-cell lung cancer histology is limited. All of these findings highlight the distinctive nature of adenocarcinoma of the lung among all lung cancer subtypes. Unfortunately, to date, less than 15% of patients with adenocarcinoma of the lung are ideal candidates for these targeted therapies. PMID:26366094

    There is a close relationship between the rate of the uterine cervix opening during parturition and the presence or absence of a completely ripened cervix. In order to learn the basic pattern of the ripening of cervix, histological and histochemical studies were performed on the human uterine cervix during pregnancy. It was noted that the collagen bundles disintegrated into fine fibers and also underwent quantitative changes during the ripening process of the cervix. During pregnancy, the number of connective tissue cells was increased, but that of mast cells was decreased. Acid mucopolysaccharides in the cervical ground substance were found to increase in late pregnancy. PMID:136067

    Objective To evaluate the effects of age and the clinical response to neoadjuvant chemotherapy (NACT) in patients with cervical cancer who received neoadjuvant chemotherapy followed by radical surgery. Methods A total of 1,014 patients with advanced cervical cancer who received NACT followed by radical surgery were retrospectively selected. Patients were divided into young (aged ≤35 years, n = 177) and older (aged >35 years, n = 837) groups. We compared the short-term responses and survival rates between the groups. The five-year disease-free survival (DFS) and overall survival (OS) rates were stratified by age, NACT response, and FIGO stage. Results The overall response rate was 86.8% in the young group and 80.9% in the older group. The young patients had an earlier FIGO stage (P<0.001), a higher rate of adenocarcinoma (P = 0.022), and more lymph node metastasis (P = 0.033) than the older patients. The presence of adenocarcinoma as the histological type (P = 0.024) and positive lymph node metastasis (P<0.001) were identified as independent risk factors for survival. When stratified by age and clinical response, young patients with no response to NACT had a worse clinicopathological condition compared with the other subgroups. Compared with non-responders, responders to NACT had a higher five-year DFS rate (80.1% versus 71.8%; P = 0.019) and OS rate (82.6% versus 71.8%; P = 0.003) among the young patients but not among the older patients. Conclusions Responders to NACT aged 35 years or younger benefitted the most from NACT, while the young non-responders benefitted the least. Age might represent an important factor to consider when performing NACT in patients with cervical cancer. PMID:26901776

    BACKGROUND Colon adenocarcinoma mostly happens at the junction of the rectum and is a common gastrointestinal malignancy. Accumulated evidence has indicated that colon adenocarcinoma develops by genetic alterations and is a complicated disease. The aim of this study was to screen differentially expressed miRNAs (DEMs) and genes with diagnostic and prognostic potentials in colon adenocarcinoma. MATERIAL AND METHODS In this study we screened DEMs and their target genes (DEGs) between 100 colon adenocarcinoma and normal samples in The Cancer Genome Atlas (TCGA) database by using the DEseq toolkit in Bioconductor. Then Go enrichment and KEGG pathway analysis were performed on the selected differential genes by use of the DAVID online tool. A regulation network of miRNA-gene was constructed and analyzed by Cytoscape. Finally, we performed ROC analysis of 8 miRNAs and ROC curves were drawn. RESULTS A total of 159 DEMs and 1921 DEGs were screened, and 1881 pairs of miRNA-target genes with significant negative correlations were also obtained. A regulatory network of miRNA-gene, including 60 cancer-related genes and 47 miRNAs, was successfully constructed. In addition, 5 clusters with several miRNAs regulating a set of target genes simultaneously were identified through cluster analysis. There were 8 miRNAs involved in these 5 clusters, and these miRNAs could serve as molecular biomarkers to distinguish colon adenocarcinoma and normal samples indicated by ROC analysis. CONCLUSIONS The identified 8 miRNAs were closely associated with colon adenocarcinoma, which may have great clinical value as diagnostic and prognostic biomarkers and provide new ideas for targeted therapy.

    BACKGROUND: Loss of cervical lordosis is a significant factor in the development of degeneration of the spine with aging. This degenerative changings of the cervical spine would cause pressure effect on the cervical root and/or medulla spinalis. AIM: Our goal is to understand the effect of the PEEK cage on cervical lordosis in the early postoperative period. Also, to interpret the effects of one- level, two- level, three-level and four- level disc pathologies on cervical lordosis. MATERIAL AND METHODS: We retrospectively investigated our archive, and we selected thirty-four patients undergoing anterior cervical discectomy and fusion with PEEK cage filled with demineralized bone matrix (ACDFP). RESULTS: We determined that ACDFP provides improvement in the cervical lordosis angle in both groups. Also, we found statistically significant difference between group 1 and 2 regarding causes of radiculomyelopathy statistically. CONCLUSION: We achieved better cervical lordotic angles at the postoperative period by implanting one-level, two-level, three-level or four-level PEEK cage filled with demineralized bone matrix. Also, the causes of cervical root and or medulla spinalis impingement were different in group1 and 2. While extruded cervical disc impingement was the first pathology in group 1, osteophyte formation was the first pathology in group 2.

    Anterior cervical spine surgery is an established surgical intervention for cervical degenerative disease and high success rate with excellent long-term outcomes have been reported. However, indications of surgical procedures for certain conditions are still controversial and severe complications to cause neurological dysfunction or deaths may occur. This review is focused mainly on five widely performed procedures by anterior approach for cervical degenerative disease; anterior cervical discectomy, anterior cervical discectomy and fusion, anterior cervical corpectomy and fusion, anterior cervical foraminotomy, and arthroplasty. Indications, procedures, outcomes, and complications of these surgeries are discussed. PMID:26119899

    This report describes two cases with obstructive jaundice caused by poorly differentiated gastric adenocarcinoma. Computed tomography scans showed circumferential stenosis in the hilar bile ducts. Endoscopic retrograde cholangiopancreatography showed dilatation of the bilateral hepatic ducts and stenosis of the common hepatic ducts from the bifurcation of the bilateral hepatic ducts. The first diagnoses were hilar cholangiocarcinoma and biliary drainage decreased serum bilirubin; however, both patients died of cancer within a short period of time. Autopsies revealed lymphatic vessel invasion and possible subepithelial invasion by gastric adenocarcinoma into the hilar bile ducts. A differential diagnosis should thus be required in suspected cases of hilar cholangiocarcinoma. PMID:27301505

    Oesophageal carcinoma has a very poor prognosis unless detected at a pre-symptomatic stage. This can only be done by screening and patients with Barrett's columnar lined epithelium of the oesophagus (CLO) are high risk candidates for an endoscopic screening programme. Surveillance studies in CLO patients, when reviewed, showed that the incidence of adenocarcinoma was between 1 in 52 and 1 in 81 patient years, with a mean of 1 in 76. This paper describes the Nottingham experience with an endoscopic screening programme that was established in 1976. To date it has detected four adenocarcinomas at a mean cost similar to that of detecting breast cancer by screening. PMID:1467783

    Gastric signet ring cell carcinoma (GSRC) is a distinct entity. Their incidence is increasing. The pathologist plays a central role in the identification of this entity. Diagnosis is based on an adenocarcinoma containing a majority of signet ring cells (above 50 %). The prognosis of GSRC is the same as gastric adenocarcinoma while GSRC appeared more aggressive. Signet ring cells present a low sensitivity to chemotherapy. This review aimed to discuss the histological, the prognostic and the therapeutic aspect of this entity. PMID:24440764

    Isolated metastases from gastric adenocarcinoma to the spleen are very infrequent. Usually, there are multiple metastases from gastric cancer, and isolated splenic metastases are very rare [Lam and Tang: Arch Pathol Lab Med 2000;124:526–530] because of certain anatomical and physiological characteristics (e.g., angulation between the splenic artery and celiac trunk, paucity of afferent lymph flow toward the spleen, contractility of the spleen and major immune content).

    Major driver mutations of pulmonary adenocarcinomas have been identified and highlighted as actionable targets for precision cancer medicine. As phenotype is largely determined by genotype, genetic changes associated with morphologic features have recently received more attention from both pathologists and clinicians. The morphologic features of adenocarcinomas with mutations in EGFR or KRAS, or translocated ALK, have rarely been described. Pulmonary adenocarcinomas with EGFR mutations, the most common driver mutation encountered in Asian patients with pulmonary adenocarcinoma, show lepidic or papillary organotypic growth patterns. KRAS-mutated adenocarcinomas demonstrate nonorganotypic growth patterns, especially mucin-containing cells. P53 mutations are associated with aggressiveness rather than growth patterns. HER2 mutations are observed in mucinous adenocarcinoma and adenocarcinoma with micropapillary features. The histologic features of BRAF-mutated adenocarcinomas have not yet been established, but papillary, lepidic, solid, and acinar patterns have been observed. Adenocarcinomas with rearrangement of ALK, ROS1, and RET genes share similar histologic features, such as solid signet-ring cells and cribriform formation. However, adenocarcinomas with NRG1 rearrangements frequently show mucinous morphology. The histologic features and related mutations of adenocarcinomas with expression of programmed cell death-1 and programmed cell death ligands-1 may be helpful in guiding immunotherapeutic treatment. This review describes histopathologic features of adenocarcinomas and their correlation with molecular alterations. PMID:27403614

    It has been reported that x-irradiation and diethylstilbestrol (DES) act synergistically on mammary adenocarcinoma formation in female ACI rats. The physical carcinogen, x-irradiation, was replaced by a chemical carcinogen, dimethylbenzanthracene (DMBA), and their interaction was studied in this system. Thirty-three female ACI rats were given 13.3 mg of DMBA per 100 grams of body weight. A total of 10 mammary adenocarcinomas were found, 8 in rats with a single mammary adenocarcinoma and 2 in a single rat, over a 266-day study period. Twenty-nine rats were implanted with a cholesterol pellet containing 5 mg of DES, and a total of 47 mammary adenocarcinomas were found, 5 in rats with a single mammary adenocarcinoma and 42 in 5 rats with 2 or more mammary adenocarcinomas. Twenty-four rats were given a combined treatment of both compounds, DES 2 days before DMBA, and a total of 126 mammary adenocarcinomas were found, 2 in rats with a single mammary adenocarcinoma and 124 in 18 rats with 2 or more mammary adenocarcinomas. The interaction between DMBA and DES was interpreted to be synergistic in regard to the proportion of rats with one or more mammary adenocarcinomas, and the median times of appearance of both first and second mammary adenocarcinomas. These interactions between DMBA and DES resemble the previously reported synergistic interactions between radiation and DES on mammary adenocarcinoma formation in female ACI rats.

    We report a case of adenocarcinoma metastatic to the abdominal wall in a 71-year-old man with a history of primary bladder adenocarcinoma. CT-guided core biopsy was performed; imprints and histologic sections showed malignant glands lined by tumor cells with hyperchromatic nuclei and prominent nucleoli, infiltrating through skeletal muscle. Immunohistochemistry revealed positivity for CK7, membranous/cytoplasmic β-catenin, caudal-type homeobox transcription factor 2 (CDX2), and α-methylacyl coenzyme A racemase and negativity for CK20, p63, prostate-specific antigen (PSA), and prostate-specific acid phosphatase (PSAP). These findings were interpreted as metastatic adenocarcinoma, consistent with bladder primary. Primary bladder adenocarcinoma is a rare malignancy arising within glandular metaplasia and is associated with cystitis cystica and cystitis glandularis. Predisposing factors include bladder exstrophy, schistosomiasis, and other causes of chronic bladder irritation. This tumor is divided into intestinal, clear cell, and signet ring cell subtypes. Treatment involves radical cystectomy with pelvic lymph node dissection, and prognosis is unfavorable. Primary bladder adenocarcinoma should be differentiated from urachal adenocarcinoma, which arises from urachal remnants near the bladder dome, and secondary adenocarcinoma, or vesical involvement by adenocarcinoma from a different primary. CK7, CK20, CDX2, thrombomodulin, and β-catenin can help distinguish primary bladder adenocarcinoma from colonic adenocarcinoma; PSA and PSAP can help distinguish primary bladder adenocarcinoma from prostate adenocarcinoma.

    A cervical cytology biobank (CCB) is an extension of current cytopathology laboratory practice consisting in the systematic storage of Pap smears or liquid-based cytology samples from women participating in cervical cancer screening with the explicit purpose to facilitate future scientific research and quality audit of preventive services. A CCB should use an internationally agreed uniform cytology terminology, be integrated in a national or regional screening registry, and be linked to other registries (histology, cancer, vaccination). Legal and ethical principles concerning personal integrity and data safety must be respected strictly. Biobank-based studies require approval of ethical review boards. A CCB is an almost inexhaustible resource for fundamental and applied biological research. In particular, it can contribute to answering questions on the natural history of HPV infection and HPV-induced lesions and cancers, screening effectiveness, exploration of new biomarkers, and surveillance of the short- and long-term effects of the introduction of HPV vaccination. To understand the limitations of CCB, more studies are needed on the quality of samples in relation to sample type, storage procedures, and duration of storage. PMID:20872354

    Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unless pulpal or periodontal infection supervenes. Radiographic features of lesions vary from well-delineated to irregularly bordered mottled radiolucencies, and these can be confused with dental caries. A characteristic radiopaque line generally separates the image of the lesion from that of the root canal, because the pulp remains protected by a thin layer of predentin until late in the process. Histopathologically, the lesions contain fibrovascular tissue with resorbing clastic cells adjacent to the dentin surface. More advanced lesions display fibro-osseous characteristics with deposition of ectopic bonelike calcifications both within the resorbing tissue and directly on the dentin surface.

    According to the GLOBOCAN statistics, cervical cancer is one of the leading causes of death among women worldwide. It is found to be gradually increasing in the younger population, specifically in the developing countries. We analyzed the protein-protein interaction networks of the uterine cervix cells for the normal and disease states. It was found that the disease network was less random than the normal one, providing an insight into the change in complexity of the underlying network in disease state. The study also portrayed that, the disease state has faster signal processing as the diameter of the underlying network was very close to its corresponding random control. This may be a reason for the normal cells to change into malignant state. Further, the analysis revealed VEGFA and IL-6 proteins as the distinctly high degree nodes in the disease network, which are known to manifest a major contribution in promoting cervical cancer. Our analysis, being time proficient and cost effective, provides a direction for developing novel drugs, therapeutic targets and biomarkers by identifying specific interaction patterns, that have structural importance.

    Objectives To describe the surgical and pathologic findings of fertility-sparing radical abdominal trachelectomy using a standardized surgical technique, and report the rate of post-trachelectomy adjuvant therapy that results in permanent sterility Methods A prospectively maintained database of all patients with FIGO stage IB1 cervical cancer admitted to the operating room for planned fertility-sparing radical abdominal trachelectomy was analyzed. Sentinel node mapping was performed via cervical injection of Technetium and blue dye. Results Between 6/2005 and 5/2008, 22 consecutive patients with FIGO stage IB1 cervical cancer underwent laparotomy for planned fertility-sparing radical abdominal trachelectomy. Median age was 33 years (range 23–43). Histology included 13 (59%) with adenocarcinoma and 9 (41%) with squamous carcinoma. Lymph-vascular invasion was seen in 9 (41%) cases. Only 3 (14%) needed immediate completion radical hysterectomy due to intraoperative findings (2 for positive nodes, 1 for positive endocervical margin). Median number of nodes evaluated was 23 (range 11–44); and 6 (27%) patients had positive pelvic nodes on final pathology – all received postoperative chemoradiation. Sixteen (73%) patients agreed to participate in sentinel node mapping which yielded a detection rate of 100%, sensitivity of 83%, specificity of 100% and false negative rate of 17%. Eighteen of 19 (95%) patients who completed trachelectomy had a cerclage placed, and 9/22 (41%) patients had no residual cervical carcinoma on final pathology. Median time in the operating room was 298 minutes (range 180–425). Median estimated blood loss was 250 ml (range 50–700), and median hospital stay was 4 days (range 3–6). No recurrences were noted at the time of this report. Conclusions Cervical adenocarcinoma and lymph-vascular invasion are common features of patients selected for radical abdominal trachelectomy. The majority of patients can undergo the operation successfully

    We reviewed 26 examples of the rare variant of cervical adenocarcinoma that has been designated "adenoma malignum." The patients, three of whom had Peutz-Jeghers syndrome, ranged in age from 25 to 72 years (average, 42 years). The most common presenting symptom was menometrorrhagia, followed by vaginal discharge, postmenopausal bleeding, and abdominal swelling in decreasing order of frequency. In 12 of the patients, the diagnosis was established on the basis of the examination of a cervical biopsy specimen, endocervical curettage specimen, or both. In three of these cases, however, up to four biopsies were performed before the diagnosis was established. In the remaining 14 patients, the diagnosis was not made until the time of operation or pathologic examination of a hysterectomy specimen. On gross examination, the cervix usually appeared abnormal, but occasional specimens were considered unremarkable. The cervix was typically described as firm or indurated. Microscopic examination showed glands that were irregular in size and shape and lined predominantly by mucin-containing columnar epithelial cells with basal nuclei. The tumors typically exhibited deep invasion of the cervical wall, and a portion of the infiltrating tumor was associated with a stromal response in most cases. Minor foci of tumor with a less well-differentiated appearance were present in 15 of the 26 tumors. Argyrophil cells were present in six of 15 tumors. Five of the six tumors containing argyrophil cells stained immunohistochemically for serotonin and peptide hormones. Positive staining for serotonin was seen in four tumors; one of these also contained a few cells positive for neurotensin. Cytoplasmic staining of the tumor cells for carcinoembryonic antigen (CEA) was seen in five of six cases. CEA reactivity was very focal in two of the positive tumors.

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

    The homeobox (HOX) genes are a family of transcription factors that bind to specific DNA sequences in target genes regulating gene expression. Thirty-nine HOX genes have been mapped in four conserved clusters: A, B, C, and D; they act as master genes regulating the identity of body segments along the anteroposterior axis of the embryo. The role played by HOX genes in adult cell differentiation is unclear to date, but growing evidence suggests that they may play an important role in the development of cancer. To study the role played by HOX genes in cervical cancer, in the present work, we analyzed the expression of HOXB genes and the localization of their transcripts in human cervical tissues. Reverse transcription-polymerase chain reaction analysis and nonradioactive RNA in situ hybridization were used to detect HOXB expression in 11 normal cervical tissues and 17 cervical carcinomas. It was determined that HOXB1, B3, B5, B6, B7, B8, and B9 genes are expressed in normal adult cervical epithelium and squamous cervical carcinomas. Interestingly, HOXB2, HOXB4, and HOXB13 gene expression was found only in tumor tissues. Our findings suggest that the new expression of HOXB2, HOXB4, and B13 genes is involved in cervical cancer.

    The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass-screening program. Furthermore, a new method has been introduced in cervical cancer screening. Therefore, the committee for cervical cancer screening in Korea updated the recommendation statement established in 2002. The new version of the guideline was developed by the committee using evidence-based methods. The committee reviewed the evidence for the benefits and harms of the Papanicolaou test, liquid-based cytology, and human papillomavirus (HPV) testing, and reached conclusions after deliberation. The committee recommends screening for cervical cancer with cytology (Papanicolaou test or liquid-based cytology) every three years in women older than 20 years of age (recommendation A). The cervical cytology combined with HPV test is optionally recommended after taking into consideration individual risk or preference (recommendation C). The current evidence for primary HPV screening is insufficient to assess the benefits and harms of cervical cancer screening (recommendation I). Cervical cancer screening can be terminated at the age of 74 years if more than three consecutive negative cytology reports have been confirmed within 10 years (recommendation D). PMID:26197860

    Background. Excisional treatment of preinvasive cervical dysplasia has been associated with adverse pregnancy outcomes. We aimed to examine trends in the rate of excisional treatment in reproductive age women in the era of HPV vaccination. Methods. National data for Australia regarding histological diagnoses of cervical dysplasia and excisional treatment for the period from 2004 to 2013 inclusive were obtained from two datasets and used to calculate age-stratified incidence rates of excisional treatment and of excisional treatments per diagnosis of dysplasia. Results. The incidence of low-grade squamous dysplasia fell in all age groups, while the incidence of high-grade dysplasia fell in the 20-to-24-year group but rose slightly for older age groups. The rate of excisional treatment fell in women aged under 35 but there was no significant change for women 35 years or older. The rate of all excisional treatments (loop excision + cone biopsy) per high-grade diagnosis (CIN2 + CIN3 + adenocarcinoma in situ) fell across all three age-bands in both datasets. Conclusion. To ensure that the use of excisional treatment is appropriate, with lower rates for younger HPV-vaccinated women, close surveillance, audit, and ongoing education will be required. PMID:27239196

    Exposure to exogenous hormones during development can result in permanent health problems. In utero exposure to diethylstilbestrol (DES) is probably the most well documented case in human history. DES, an orally active synthetic estrogen, was believed to prevent adverse pregnancy outcome and thus was routinely given to selected pregnant women from the 1940s to the 1960s. It has been estimated that 5 million pregnant women worldwide were prescribed with DES during this period. In the early 1970s, vaginal clear cell adenocarcinomas (CCACs) were diagnosed in daughters whose mother took DES during pregnancy (known as DES daughters). Follow up studies demonstrated that exposure to DES in utero causes a spectrum of congenital anomalies in female reproductive tracts and CCACs. Among those, cervical and vaginal adenoses are most commonly found, which are believed to be the precursors of CCACs. Transformation related protein 63 (TRP63/p63) marks the cell fate decision of Müllerian duct epithelium (MDE) to become squamous epithelium in the cervix and vagina. DES disrupts the TRP63 expression in mice and induces adenosis lesions in the cervix and vagina. This review describes mouse models can be used to study the development of DES-induced anomalies, focusing on cervical and vaginal adenoses, and discusses its molecular pathogenesis. PMID:22682699

    Cancer of the uterine cervix is the second largest cause of cancer deaths in women, and its toll is greatest in populations that lack screening programmes to detect precursor lesions. Persistent infection with ‘high risk’ genotypes of human papillomavirus (HPV) is necessary, although not sufficient, to cause cervical carcinoma. Therefore, HPV vaccination provides an opportunity to profoundly affect cervical cancer incidence worldwide. A recently licensed HPV subunit vaccine protects women from a high proportion of precursor lesions of cervical carcinoma and most genital warts. Here we examine the ramifications and remaining questions that surround preventive HPV vaccines. PMID:16990853

    Recent studies have suggested the involvement of a unique population of cells at the cervical squamo-columnar junction (SCJ) in the pathogenesis of early (squamous intraepithelial lesion or SIL) and advanced (squamous cell and adeno-carcinomas) cervical neoplasia. However, there is little evidence to date showing that SCJ cells harbour carcinogenic HPV or are instrumental in the initial phases of neoplasia. This study was designed to (1) determine if normal-appearing SCJ cells contained evidence of carcinogenic HPV infection and (2) trace their transition to early SIL. Sections of cervix from high-risk reproductive age women were selected and SCJ cells were analysed by using several techniques which increasingly implicated HPV infection: HPV DNA (genotyping and in situ hybridization)/RNA (PCR), immunostaining for HPV16 E2 (an early marker of HPV infection), p16(ink4), Ki67, and HPV L1 protein. In 22 cases with a history of SIL and no evidence of preneoplastic lesion in the excision specimen, HPV DNA was isolated from eight of ten with visible SCJ cells, six of which were HPV16/18 DNA-positive. In five of these latter cases, the SCJ cells were positive for p16(ink4) and/or HPV E2. Transcriptionally active HPV infection (E6/E7 mRNAs) was also detected in microdissected SCJ cells. Early squamous atypia associated with the SCJ cells demonstrated in addition diffuse p16(ink4) immunoreactivity, elevated proliferative index, and rare L1 antigen positivity. We present for the first time direct evidence that normal-appearing SCJ cells can be infected by carcinogenic HPV. They initially express HPV E2 and their progression to SIL is heralded by an expanding metaplastic progeny with increased proliferation and p16(ink4) expression. Whether certain SCJs are more vulnerable than others to carcinogenic HPV genotypes and what variables determine transition to high-grade SIL remain unresolved, but the common event appears to be a vulnerable cell at the SCJ.

    The underlying molecular alterations in chronic idiopathic inflammatory bowel disease-associated intestinal adenocarcinoma remain largely unknown. Somatic IDH mutations are often seen in gliomas and myeloid leukemia but have also been recently reported in a subset of other neoplasms. We analyzed a series of intestinal adenocarcinomas with (n=23) and without (n=39) associated chronic idiopathic inflammatory bowel disease treated at our institution for IDH1 and IDH2 mutations and correlated the clinicopathologic findings with mutation status. Compared with intestinal adenocarcinomas not associated with inflammatory bowel disease, adenocarcinomas associated with inflammatory bowel disease more frequently demonstrated IDH mutations (13% vs. 0%, P=0.047). All IDH mutations were identified in IDH1 and resulted in substitution of arginine by cysteine at position 132 (p.R132C, c.394C>T). IDH1 mutations were frequently (66%) associated with concurrent KRAS mutations (p.G12D, c.35G>A). IDH1-mutated intestinal adenocarcinomas were seen in the setting of both Crohn disease and ulcerative colitis and were located in both the ileum and colon. Compared with IDH1-negative inflammatory bowel disease-associated adenocarcinoma, IDH1-positive adenocarcinomas more frequently demonstrated tubuloglandular histology (100% vs. 25%, P=0.032) and were more frequently associated with precursor lesions exhibiting serrated morphology (66% vs. 6%, P=0.034). IDH1 mutations were also identified in the precursor dysplastic lesions associated with IDH1-positive adenocarcinomas. In conclusion, we demonstrate that IDH1 mutations are occasionally identified in inflammatory bowel disease-associated intestinal adenocarcinoma but not in intestinal adenocarcinoma not associated with inflammatory bowel disease. In addition, IDH1-mutated intestinal adenocarcinoma is associated with a characteristic low-grade tubuloglandular histology and often harbors concurrent KRAS mutations. Identification of patients

    The relative frequency of regional lymphogenic versus distant hematogenic metastases was evaluated in 369 patients with sinonasal adenocarcinoma of the intestinal type (ITAC). We assessed the results of neck dissections for a limited number of patients undergoing this surgical intervention. 117 ITAC patients were followed up for at least 5 years. Neck dissections were performed in 18 cases (15 primary and 3 secondary operations), 4 of which revealed carcinoma-positive lymph nodes. Metastases in lymph nodes were also diagnosed clinically in three other patients adding up to a total of seven individuals (6 % of 117) with lymphogenic metastases. In comparison, distant hematogenic metastases were identified in 15.4 % of these 117 patients. In the second group of 252 patients, the occurrence of distant hematogenic metastases and colorectal adenocarcinomas was registered but no formal follow-up procedure was applied. 50 neck dissections were performed in this group, 46 of which exhibited no histological evidence for metastases in lymph nodes, while in 1 case they were carcinoma-positive. Three additional cases showed clinical signs of metastases in regional lymph nodes. Taken together, our observations indicate that regional lymphogenic metastases are rather rare (about 2 %) in patients with sinonasal adenocarcinoma of the intestinal type. Therefore, the surgery of neck dissection appears not advised as routine intervention in these cases. ITAC patients show a normal prevalence of colorectal adenocarcinomas. PMID:25753257

    To identify chromosomal loci involved in the development of proximal gastric adenocarcinoma, this study delineated the pattern of allelic imbalance in a series of 38 adenocarcinomas arising in the gastric cardia. A total of 137 microsatellite markers covering all autosomal arms, excluding acrocentric arms, were analysed. A mean of 35 out of a total of 39 chromosomal arms studied were informative for each patient. The tumour group demonstrated a high level of allelic imbalance, with an observed median fractional allelic imbalance of 0.47 for the 29 intestinal-type adenocarcinomas and 0.54 for the nine diffuse-type adenocarcinomas. Allelic imbalance was detected in >50% of informative cases in both histological subtypes on a number of chromosomal arms. In the intestinal subtype, these included, 3p (61%), 4q (71%), 5q (59%), 8p (60%), 9p (65%), 9q (83%), 12q (52%), 13q (52%), 17p (78%) and 18q (70%). A higher incidence of allelic imbalance was detected on chromosome 16q in tumours of the diffuse type relative to those of the intestinal type. A more detailed mapping on chromosomes 4q and 6q identified a number of cases with subchromosomal breakpoints. In conclusion, this analysis has indicated regions of the genome potentially involved in the development of proximal gastric carcinomas. Images Figure 1 Figure 2 Figure 4 PMID:9400942

    A 61-year-old female with pancreatic body cancer underwent a distal pancreatectomy. The tumor was a moderately- to poorly-differentiated adenocarcinoma. Tumor growth filled the dilated main pancreatic duct (MPD) and infiltrated the surrounding area. Six months later, metastases to the left diaphragm and MPD of the remnant pancreatic head were detected. Chemoradiotherapy was administered, but the patient succumbed 22 months after surgery. An autopsy demonstrated that a moderately- to poorly-differentiated adenocarcinoma had arisen from the pancreatic head and infiltrated the duodenum and bile duct. Huge liver metastases and multiple peritoneal disseminations were also present. Microscopically, a portion of the tumor had a pseudo-rosette appearance in the adenocarcinoma component, while another section showed characteristics of a neuroendocrine tumor (NET) immunohistochemically. The original surgically-resected tumor also showed NET characteristics immunohistochemically. It is therefore necessary to search for NET components in pancreatic cancer with atypical growth and metastases, even when adenocarcinoma has been diagnosed histologically. PMID:24944667

    Collision tumors are thought to arise from the accidental meeting of two independent tumors. Adenocarcinoma is the most common malignant rectal tumor, while neuroendocrine tumor (NET) is relatively rare. Due to the endoscopy and reporting, the overall incidence of NETs was increasing recently but still less than 1 per 100,000. This means that a combination of an adenocarcinoma and NET is a very rare finding and an actual collision of these tumors even more so. We report here a highly unusual case of a 64-year-old woman who had collision tumors composed of a primary rectal adenocarcinoma and NET showing a "side by side" pattern. Resection margins are free of both the tumors. The postoperative course was uneventful. The patient underwent a protocol CT scan at 3 months after surgery, which did not show any recurrence. Both the malignant adenocarcinoma and the NET would make a great influence in the rest lifetime and a follow up will be continued, although the CT did not show any recurrence until now. To the best of our knowledge, this is the first reported case of such an occurrence. PMID:25972691

    Objective Irreversible electroporation (IRE) of locally advanced pancreatic adenocarcinoma of the neck has been used to palliate appropriate stage 3 pancreatic cancers without evidence of metastasis and who have undergone appropriate induction therapy. Currently there has not been a standardized reported technique for pancreatic mid-body tumors for patient selection and intra-operative technique. Patients Subjects are patients with locally advanced pancreatic adenocarcinoma of the body/neck who have undergone appropriate induction chemotherapy for a reasonable duration. Main outcome measures Technique of open IRE of locally advanced pancreatic adenocarcinoma of the neck/body is described, with the emphasis on intra-operative ultrasound and intra-operative electroporation management. Results The technique of open IRE of the pancreatic neck/body with bracketing of the celiac axis and superior mesenteric artery with continuous intraoperative ultrasound imaging and consideration of intraoperative navigational system is described. Conclusions IRE of locally advanced pancreatic adenocarcinoma of the body/neck is feasible for appropriate patients with locally advanced unresectable pancreatic cancer. PMID:26029461

    AIM: To explore the inhibitory effects of dobutamine on gastric adenocarcinoma cells. METHODS: Dobutamine was used to treat gastric adenocarcinoma cells (SGC-7901) and cell viability was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The effects of dobutamine combined with cisplatin on cell viability were also analyzed. Cell migration was studied using the wound healing assay, and cell proliferation was analyzed using the colony formation assay. A cell invasion assay was carried out using Transwell cell culture chambers. The cell cycle and cell apoptosis were analyzed by flow cytometry. Western blot and immunocytochemistry were performed to determine the expression of Yes-associated protein (YAP) in treated cells. RESULTS: Dobutamine significantly inhibited cell growth, migration, cell colony formation, and cell invasion into Matrigel. Dobutamine also arrested the cell cycle at G1/S phase, and increased the rate of apoptosis of gastric adenocarcinoma cells. The expression of YAP was detected mainly in the nucleus in the absence of dobutamine. However, reduced expression of phosphorylated YAP was mainly found in the cytosol following treatment with dobutamine. CONCLUSION: Dobutamine has significant inhibitory effects on gastric adenocarcinoma cells and may be used in neoadjuvant therapy not only for gastric cancer, but also for other tumors. PMID:25493021

    Introduction Lung cancer remains the leading cause of cancer-related deaths in the US and worldwide. Adenocarcinoma is the most common type of lung cancer and encompasses lesions with widely variable clinical outcomes. In the absence of noninvasive risk stratification, individualized patient management remains challenging. Consequently a subgroup of pulmonary nodules of the lung adenocarcinoma spectrum is likely treated more aggressively than necessary. Methods Consecutive patients with surgically resected pulmonary nodules of the lung adenocarcinoma spectrum (lesion size ≤ 3 cm, 2006–2009) and available pre-surgical high-resolution computed tomography (HRCT) imaging were identified at Mayo Clinic Rochester. All cases were classified using an unbiased Computer-Aided Nodule Assessment and Risk Yield (CANARY) approach based on the quantification of pre-surgical HRCT characteristics. CANARY-based classification was independently correlated to postsurgical progression-free survival. Results CANARY analysis of 264 consecutive patients identified three distinct subgroups. Independent comparisons of 5-year disease-free survival (DFS) between these subgroups demonstrated statistically significant differences in 5-year DFS, 100%, 72.7% and 51.4%, respectively (p = 0.0005). Conclusions Non-invasive CANARY based risk stratification identifies subgroups of patients with pulmonary nodules of the adenocarcinoma spectrum characterized by distinct clinical outcomes. This technique may ultimately improve the current expert opinion-based approach to the management of these lesions by facilitating individualized patient management. PMID:25170645

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space.

    We aimed to investigate clinicopathological features and histology of ALK-rearranged adenocarcinomas with extensive mucin production (AEM) that mimic mucinous adenocarcinoma (MA). Retrospectively, 12 cases of AEM and 25 cases of MA harbouring KRAS mutation were retrieved. The clinicopathological profile and detailed histological features were analysed and compared based on the ALK and KRAS status. AEMs occurred in younger patients (p = 0.044) and were characterised by floating tubulopapillary pattern (p < 0.001), prominent nucleolus (p < 0.001), and apical cytoplasmic snouts (p < 0.001). In contrast, KRAS-mutated MAs lacked ALK-specific histological patterns (p < 0.05). Instead, tumour-infiltrating leukocytes (p = 0.018) and smooth cytoplasmic borders (p < 0.001) with vesicular nuclei (p = 0.004) were prominent in KRAS-mutated MAs. AEMs demonstrated characteristic tubulopapillary pattern and apical snouts, which were distinguishing features from MAs with KRAS mutation. Apical snouts can be a useful histological surrogate for ALK rearrangement in the pulmonary adenocarcinomas showing extensive mucin that mimic MA. PMID:27114375

    Cervical carcinoma is a malignant tumor that poses a serious threat to women's health and survival. Approximately 10-25% of cervical cancers are adenocarcinomas (ACs). AC has high rates of recurrence and mortality, while there is no effective treatment for now. Zeylenone (Zey), which is isolated from an ethanol extract of the leaves of Uvaria grandiflora Roxb. of the family Annonaceae, has shown potent inhibitory activity against various tumor cells, including cervical carcinoma cells. To gain insight into the molecular mechanism underlying the effect of Zey on AC, we quantified protein expression changes in AC cells treated with Zey. We used stable isotope labeling with amino acids in cell culture (SILAC) in combination with high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS) and bioinformatics analysis to compare protein expression profiles in HeLa cells before and after Zey treatment. Of 1805 differentially expressed proteins identified, 229 were screened as key protein molecules and classified into nine categories. Profiling of differentially-expressed proteins contributed to our understanding of the molecular mechanism by which Zey induces HeLa cell apoptosis. Using this method, candidate targets can be identified for developing new drugs against cervical carcinoma. PMID:26130516

    For a better understanding of the consequences of recurrent chromosomal alterations in cervical carcinomas, we integrated genome-wide chromosomal and transcriptional profiles of 10 squamous cell carcinomas (SCCs), 5 adenocarcinomas (AdCAs) and 6 normal controls. Previous genomic profiling showed that gains at chromosome arms 1q, 3q, and 20q as well as losses at 8q, 10q, 11q, and 13q were common in cervical carcinomas. Altered regions spanned multiple megabases, and the extent to which expression of genes located there is affected remains unclear. Expression analysis of these previously chromosomally profiled carcinomas yielded 83 genes with significantly differential expression between carcinomas and normal epithelium. Application of differential gene locus mapping (DIGMAP) analysis and the array CGH expression integration tool (ACE-it) identified hotspots within large chromosomal alterations in which gene expression was altered as well. Chromosomal gains of the long arms of chromosome 1, 3, and 20 resulted in increased expression of genes located at 1q32.1-32.2, 3q13.32-23, 3q26.32-27.3, and 20q11.21-13.33, whereas a chromosomal loss of 11q22.3-25 was related to decreased expression of genes located in this region. Overexpression of DTX3L, PIK3R4, ATP2C1, and SLC25A36, all located at 3q21.1-23 and identified by DIGMAP, ACE-it or both, was confirmed in an independent validation sample set consisting of 12 SCCs and 13 normal ectocervical samples. In conclusion, integrated chromosomal and transcriptional profiling identified chromosomal hotspots at 1q, 3q, 11q, and 20q with altered gene expression within large commonly altered chromosomal regions in cervical cancer.

    Gastric adenocarcinoma, a single heterogeneous disease with multiple epidemiological and histopathological characteristics, accounts for approximately 10% of cancers worldwide. It is categorized into four histological types: papillary adenocarcinoma (PAC), tubular adenocarcinoma (TAC), mucinous adenocarcinoma (MAC), and signet ring cell adenocarcinoma (SRC). Effective differentiation of the four types of adenocarcinoma will greatly improve the treatment of gastric adenocarcinoma to increase its five-year survival rate. We reported here the differentiation of the four histological types of gastric adenocarcinoma from the molecularly structural viewpoint of confocal Raman microspectroscopy. In total, 79 patients underwent laparoscopic or open radical gastrectomy during 2008-2011: 21 for signet ring cell carcinoma, 21 for tubular adenocarcinoma, 14 for papillary adenocarcinoma, 6 for mucinous carcinoma, and 17 for normal gastric mucosas obtained from patients underwent operation for other benign lesions. Clinical data were retrospectively reviewed from medical charts, and Raman data were processed and analyzed by using principal component analysis (PCA) and linear discriminant analysis (LDA). Two-dimensional plots of PCA and LDA clearly demonstrated that the four histological types of gastric adenocarcinoma could be differentiated, and confocal Raman microspectroscopy provides potentially a rapid and effective method for differentiating SRC and MAC from TAC or PAC.

    Bile reflux is a risk factor in the development of intestinal metaplasia in the stomach and is believed to function as an initiator of gastric carcinogenesis. However, whether the G protein-coupled bile acid receptor TGR5 is expressed in this tumor is not known. In this study, we determined the expression of TGR5 in gastric adenocarcinoma and examined the role of TGR5 in cell proliferation. Strong TGR5 staining was present in 12% of cases of intestinal metaplasia but in no cases of normal gastric epithelium (P < 0.01). Moderate to strong TGR5 membranous and cytoplasmic staining was present in 52% of the intestinal but in only 25% of the diffuse subtype of adenocarcinomas (P < 0.001). Kaplan-Meier univariate survival analysis revealed that moderate to strong TGR5 staining was associated with decreased patient survival (P < 0.05). Treatment with taurodeoxycholic acid (TDCA, a bile acid) significantly increased thymidine incorporation in the AGS gastric adenocarcinoma cell line, suggesting that bile acids may increase cell proliferation. This increase was significantly decreased by knockdown of TGR5 with TGR5 small-interfering RNA (siRNA). In addition, overexpression of TGR5 significantly enhanced TDCA-induced increases in thymidine incorporation. TGR5 is coupled with G(q)α and Gα(i-3) proteins. TDCA-induced increase in thymidine incorporation was significantly decreased by knockdown of G(q)α and Gα(i-3) with their siRNAs. We conclude that TGR5 is overexpressed in most gastric intestinal-type adenocarcinomas, and moderate to strong TGR5 staining is associated with decreased patient survival in all gastric adenocarcinomas. Bile acids increase cell proliferation via activation of TGR5 receptors and G(q)α and Gα(i-3) proteins. PMID:23238937

    Opium use has been associated with higher risk of cancers of the esophagus, bladder, larynx, and lung; however, no previous study has examined its association with gastric cancer. There is also little information on the associations between hookah (water pipe) smoking or the chewing of tobacco products and the risk of gastric cancer. In a case-control study in Golestan Province of Iran, we enrolled 309 cases of gastric adenocarcinoma (118 noncardia, 161 cardia and 30 mixed-location adenocarcinomas) and 613 matched controls. Detailed information on long-term use of opium, tobacco products and other covariates were collected using structured and validated lifestyle and food frequency questionnaires. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were obtained using conditional logistic regression models. Opium use was associated with an increased risk of gastric adenocarcinoma, with an adjusted OR (95% CI) of 3.1 (1.9-5.1), and this increased risk was apparent for both anatomic subsites (cardia and noncardia). There was a dose-response effect, and individuals with the highest cumulative opium use had the strongest association (OR: 4.5; 95% CI: 2.3-8.5). We did not find a statistically significant association between the use of any of the tobacco products and risk of gastric adenocarcinoma, overall or by anatomic subsite. We showed, for the first time, an association between opium use and gastric adenocarcinoma. Given that opium use is a traditional practice in many parts of the world, these results are of public health significance. PMID:23319416

    Endometrial adenocarcinoma is a common gynecological malignancy that is usually treated by surgical resection followed by radiation. However, the frequency of remote metastasis is high. The present study aimed to investigate whether patients with endometrial adenocarcinoma exhibited a positive response to treatment with a gonadotropin-releasing hormone analogue or inhibitors of neoangiogenesis, which are applied for the treatment of other malignancies. Immunohistochemical analyses were performed using 203 paraffin-embedded tissue samples of endometrial adenocarcinomas from patients who had undergone surgery at the Department of Obstetrics and Gynecology of the Ludwig Maximilians University of Munich, Germany. The tissues were incubated with antibodies against luteinizing hormone/choriogonadotropin receptor (LHCGR) and vascular endothelial growth factor receptor 2 (VEGFR2), and evaluated by bright field microscopy. The staining was categorized according to the Immune-Reactive-Score (IRS). The IRS scores were then statistically associated with various tumor traits, including tumor size, lymph node status, metastasis, grade, expression of steroid hormone receptors and patient survival. There was a significant association between VEGFR2 expression and tumor grading and estrogen receptor-α (ERα). For LHCGR, a correlation was observed with ERα and progesterone receptor (PR). No correlations were identified between VEGFR2 or LHCGR expression and the other examined tumor traits or patient survival. The associations between VEGFR2 and ERα, and between LHCGR and ERα or PR, may be explained by the interaction of these signal transduction molecules in the regulation of cellular growth and differentiation. These mechanisms also have an important role in the formation of remote metastases, which is the main cause for tumor-associated mortality. The results of the present study suggested that patients with endometrial adenocarcinoma may benefit from treatment with inhibitors

    Thymidylate synthase (TYMS) is an important chemotherapeutic target in non-small cell lung cancer (NSCLC). Arsenic trioxide (ATO) has been shown to suppress TYMS in a colonic cancer model. We examined the effects of TYMS suppression by ATO in lung adenocarcinoma. A panel of 4 lung adenocarcinoma cell lines was used to determine the effects of ATO treatment on cell viability, TYMS expression (protein and mRNA), E2F1 protein expression and TYMS activity. TYMS knockdown and overexpression were performed. Tumor growth inhibition in vivo was studied using a nude mouse xenograft model. ATO showed antiproliferative effects with clinically achievable concentrations (around 1.1-6.9 µM) in 4 lung adenocarcinoma cell lines. Downregulation of TYMS protein and mRNA expression, reduced TYMS activity, and suppressed E2F1 expression were demonstrated in lung adenocarcinoma with ATO. Cell viability was reduced by 15-50% with TYMS knockdown. Overexpression of TYMS led to a 2.7-fold increase in IC50 value with ATO treatment in H358 cells, but not in H23 cells. Using a xenograft model with H358 cell line, relative tumor volume was reduced to 44% that of the control following 8 days of treatment with 7.5 mg/kg ATO, and associated with significant downregulation of TYMS protein expression. In conclusion, ATO has potent in vitro and in vivo activity in lung adenocarcinoma, and is partially mediated by transcriptional downregulation of TYMS. PMID:24691991

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

  19. Airway management in cervical spine injury

    PubMed Central

    Austin, Naola; Krishnamoorthy, Vijay; Dagal, Arman

    2014-01-01

    To minimize risk of spinal cord injury, airway management providers must understand the anatomic and functional relationship between the airway, cervical column, and spinal cord. Patients with known or suspected cervical spine injury may require emergent intubation for airway protection and ventilatory support or elective intubation for surgery with or without rigid neck stabilization (i.e., halo). To provide safe and efficient care in these patients, practitioners must identify high-risk patients, be comfortable with available methods of airway adjuncts, and know how airway maneuvers, neck stabilization, and positioning affect the cervical spine. This review discusses the risks and benefits of various airway management strategies as well as specific concerns that affect patients with known or suspected cervical spine injury. PMID:24741498

  20. Congenital narrowing of the cervical spinal canal.

    The clinical and laboratory findings in six patients with congenital narrowing of the cervical spinal canal and neurological symptoms are described. A variable age of onset and an entirely male occurrence were found. Signs and symptoms of spinal cord dysfunction predominated in all but one patient. Symptoms were produced in five patients by increased physical activity alone. Congenital narrowing of the cervical spinal canal may result in cord compression without a history of injury and occasionally without evidence of significant bony degenerative changes. The clinical features may be distinguishable from those found in cervical spondylosis without congenital narrowing. Intermittent claudication of the cervical spinal cord appears to be an important feature of this syndrome. Surgery improved four out of five people. PMID:1219087

    Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO’M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS) for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI) and the Centre for Epidemiologic Studies Depression questionnaire (CES-D). Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64). Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision. PMID:23125494

    Grading of cervical dysplasias at colposcopy by means of rapid frozen section avoids the delay inevitable with paraffin sections. The immediacy of the diagnosis benefits the patient, who can be treated at her first visit. A comparison of grading by frozen sections with paraffin sections has confirmed the safety of the frozen method. Additional advantages are opportunities for optimum orientation and "rescue" of specimens, improved colposcopic training, and the facilitation of special investigations on fresh cervical tissue.

    Gout is a common metabolic disorder typically affecting the distal joints of the appendicular skeleton. Involvement of the axial skeleton, particularly the facet joints and posterior column of the cervical spine, is rare. This case report highlights such a presentation in a 76-year old female who presented with cervical spine pain following a fall. Her radiological findings were suggestive of a destructive metastatic process. Histological diagnosis confirmed tophaceous gout. PMID:16028084

    The use of hormone-releasing intrauterine devices has been on the increase for the last three decades. To date, evidence of their long-term efficiency is available. The aim of the present paper was to briefly review beneficial prophylactic effects of the levonorgestrel-releasing intrauterine system on the incidence of a variety of malignancies in women. Such an influence is of a particular importance in the light of the currently observed increased prevalence of endometrial and cervical adenocarcinomas. Low-dose releasing intrauterine systems are also available, but the hard evidence-based medical data have been derived primarily for Mirena® (Bayer) device, which topically releases from 20 to 14 pg of levonorgestrel daily. Consequently the risk of developing endometrial carcinoma in Mirena® users is lowered by as much as 50% compared with the general population risk To a lesser extent, the intrauterine system decreases the risk for cervical adenocarcinoma and squamous cell carcinoma, as well as ovarian, pancreas, and lung carcinomas. In one population-based study Mirena® increased the risk for breast carcinoma by approximately 20%, whereas a number of other studies failed to demonstrate such a hazard. In the recent decades of the increased predominance of insulin resistance and obesity and an occurrence of hormone-dependent carcinomas at earlier age, a broad application of levonorgestrel-releasing intrauterine systems may become a particularly important component of primary prevention of malignancies in women. Both obese and overweight patients seem perfect candidates for such a hormonal intervention. PMID:26117991

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature. PMID:27103865

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.

  10. Cervical cerclage: a review of the evidence.

    2008-01-01

    Cervical insufficiency is a difficult and confusing diagnosis. Its diagnostic criteria, etiology, and treatment are all debated. Cervical cerclage has been a common practice in obstetrics since it was first described by Shirodker and then McDonald in the 1950s. Cerclages have been placed because of a patient's obstetrical history, physical examination, ultrasound, or a combination of the above. However, the data supporting cerclage placement is limited. There has never been a prospective, randomized, controlled trial of cerclage versus no cerclage in patients with a classic history of cervical insufficiency (multiple painless second trimester losses occurring at progressively earlier gestational ages). This article attempts to review the relevant studies regarding cerclage placement for the treatment of cervical insufficiency. Based on the current literature, there is evidence supporting cervical cerclage in the following limited circumstances: a history of 3 or more spontaneous preterm births or second trimester losses; a high-risk patient with a singleton pregnancy who has a short cervix in the second trimester. Because the majority of patients with risk factors for preterm birth and second trimester loss (poor obstetric history, short cervix) will still deliver at term or near-term, studies on the effectiveness of cervical cerclage would need many patients to be powered appropriately.

    Invasive cervical cancer is rare during a pregnancy, even though it is one of the most frequently diagnosed neoplasias during that time. It is noted that around 30% of women diagnosed with cervical cancer are of reproductive age. This means that up to 3% of cases of cervical cancer are found in pregnant women or those who are in the post-birth period. A cervicovaginal Pap smear is performed as part of the regular checkup for a pregnant woman during the first visit so that cervical cancer can easily be diagnosed early in these women, detecting it early in up to 70–80% of cases. We present here the case of a patient with initial diagnosis of cervical cancer made around 20th week of pregnancy. It was then treated by a simple trachelectomy and cerclage during week 24. The pregnant woman gave birth to a healthy baby at the end of her pregnancy. Definitive treatment was completed three months after giving birth with a total hysterectomy and laparoscopic bilateral salpingectomy while preserving both ovaries. After 17 months of monitoring the patient showed no signs of reoccurrence. In conclusion, during the early stage of cervical cancer conservative management may be a reasonable option to preserve the current pregnancy. PMID:27610199

    For many years it has been thought that a significant proportion of cervical cancer could be attributed to sexually transmitted agents, such as sperm, smegma, Treponema pallidum, Gonococcus and herpes simplexvirus type 2. Recent advances of molecular biology, however, have revealed that human papillomavirus (HPV) might be the most causative virus of the disease. Since HPV type 16 DNA was found in a patient with cervical cancer in 1983, many HPV types have been cloned from cervical cancers, also from premalignant lesions (intraepithelial neoplasias). In Japan, we have found 6 new types of HPV (HPV 58, 59, 61, 62, 64, 67) in the female genital tract so far. Especially, HPV 58, which was cloned from a patient with cervical squamous cell carcinoma and was already fully sequenced, is thought to be an important agent for the development of cervical cancer as well as HPV 16. Now we are investigating extensively to clarify the real relationship between genital HPV infection and cervical cancer. PMID:1327090

    Objective  The objective of this study was to describe pregnancy outcomes, including cervical insufficiency and preterm birth, in the subsequent pregnancy following an intrapartum cervical laceration. Study Design  Retrospective cohort of women with their first two consecutive singleton pregnancies carried to ≥ 200/7 weeks' gestation within a tertiary health care system from 2002 to 2012. Cervical laceration cases were identified by ICD9 codes and included if suture repair was required. Results  In this study, 55 women were confirmed to have a cervical laceration in the first delivery; 43 lacerations after vaginal delivery (VD) and 12 after cesarean delivery (CD). The median gestational age of the first delivery was 400/7 weeks and the median birth weight 3,545 g; these did not differ between VD and CD. In the second pregnancy, 2 of 55 women (4.6%) had a prophylactic cerclage placed; 1 carried to term and the other delivered at 356/7 weeks. In total, four women (9.3%) delivered the second pregnancy < 37 weeks: three had a prior term VD and one had a prior 34 weeks VD. There was only one case of recurrent cervical laceration, occurring in the setting of vaginal deliveries. Conclusion  Obstetric cervical lacerations are uncommon. Complications in the following pregnancy were low, despite lack of additional prophylactic cerclage use. PMID:27621953

    Woods, Barrett I; Hilibrand, Alan S

    2015-06-01

    Cervical radiculopathy is a relatively common neurological disorder resulting from nerve root dysfunction, which is often due to mechanical compression; however, inflammatory cytokines released from damaged intervertebral disks can also result in symptoms. Cervical radiculopathy can often be diagnosed with a thorough history and physical examination, but an magnetic resonance imaging or computed tomographic myelogram should be used to confirm the diagnosis. Because of the ubiquity of degenerative changes found on these imaging modalities, the patient's symptoms must correlate with pathology for a successful diagnosis. In the absence of myelopathy or significant muscle weakness all patients should be treated conservatively for at least 6 weeks. Conservative treatments consist of immobilization, anti-inflammatory medications, physical therapy, cervical traction, and epidural steroid injections. Cervical radiculopathy typically is self-limiting with 75%-90% of patients achieving symptomatic improvement with nonoperative care. For patients who are persistently symptomatic despite conservative treatment, or those who have a significant functional deficit surgical treatment is appropriate. Surgical options include anterior cervical decompression and fusion, cervical disk arthroplasty, and posterior foraminotomy. Patient selection is critical to optimize outcome. PMID:25985461

    Altered expression of cullin-5 (CUL5), a member of the cullin-RING E3 ubiquitin ligase family, has been implicated in a number of types of cancers including breast, cervical and hepatocellular cancers. In the present study, we found that CUL5 expression was significantly decreased in both endometrioid and serous endometrial adenocarcinomas with the more aggressive serous type displaying a higher reduction (−4.3-fold) than the less aggressive endometrioid type (−2.9-fold). Overexpression of CUL5 mRNA and protein in Ishikawa H endometrial cancer cells resulted in decreased cell proliferation and in a reduction in CUL5-RING E3 ligase downstream clients JAK2 and FAS-L. Finally, we demonstrated for the first time that CUL5 is a direct target of miR-182 that we previously showed to be significantly overexpressed in endometrial adenocarcinomas and we provided evidence that increased miR-182 expression is, at least in part, a result of demethylation of its upstream promoter. These data suggest a cascade in which miR-182 expression is epigenetically increased leading to decreased CUL5 expression and increased cellular proliferation. The final step in the cascade may be operating through a decrease in ubiquitination of pro-growth CUL5 ubiquitin ligase clients. This cascade offers a series of potential interventional steps involving epigenetic modification, miRNA and/or gene targeting and ubiquitination. PMID:26847831

    The anthors studied the morphological features of uterine adenocarcinoma using immunohistochemical methods. The endometrial tissue was studed resulting from surgery - hysterectomy with oophorectomy in 103 patients aged 45-76 years with a clinical diagnosis of endometrial cancer. To exclude false-positive and false-negative results, we carry out same investigation on 12 patients with morphological diagnosis easy-glandular hyperplasia of the endometrium. The results showed that the endometrioid adenocarcinomas exhibit the high and moderate expression of estrogen and progesterone receptors and low rate of the proliferation marker Ki-67. For serous-paapillary andenocarcionoma of the uterine body the negative ER-PR-receptor over expression phenotype and proliferation marker Ki-67 superexpression are characteristic. The results showed that in a simple-glandular endometrial hyperplasia is determined a moderate expression of estrogen and progesterone receptors, as for the Ki-67 proliferation marker an expression was found only in the single arears with an average of 5-8% of findings. Based at shis study it may be concluded thate the use of immunohistochemical studies particularly a detection of negative estrogen and progesterone resceptor phenotype and high expression of the proliferation marker Ki-67 is an additional defferential diagnostic eriterion for the diagnosis of serous papillary adenocarcinoma of the uterine body thet will ensure adepuate therapeutis approach to patients suffering from this disorder.

    Purpose To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Materials and Methods Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. Results The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. Conclusion PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered. PMID:26157680

    Background Cervical cancer is the third largest cause of cancer mortality in India. The objectives of the study were to compare the pre and the post treatment quality of life in cervical cancer patients and to develop a prediction model to provide an insight into the possibilities in the treatment modules. Methodology/Principal Findings A total of 198 patients were assessed with two structured questionnaires of Health Related Quality of Life (The European Organisation for Research and Treatment of Cancer, EORTC QLQ C-30 and CX-24). The baseline observations were recorded when the patients first reported (T1) and second evaluation was done at 6 months post treatment (T2). The mean age of detection was 50.9 years with the literacy level being non-educated or less than high school. Majority of them were married/cohabiting 179 (90.4%). On histopathological examination (HPE) squamous cell carcinoma was found to be the most common cell type carcinoma 147 (74.2%) followed by Adenocarcinoma 31 (15.7%). Radical hysterectomy was the most common treatment modality 76 (38.4%), followed by Wertheims Hysterectomy 46 (23.2%) and Radiochemotherapy 59 (29.8%). The mean score of global health of cervical cancer patients post treatment was 77.90, which was significantly higher than the pre - treatment score (54.32). Mean “symptoms score” post treatment was 21.69 with an aggravation of 7.32 compared to pre treatment scores. Patients experienced substantial decrease in sexual activity post treatment. Conclusions/Significance The prediction model(PrediQt-Cx), based on Support Vector Machine(SVM) for predicting post treatment HRQoL in cervical cancer patients was developed and internally cross validated. After external validation PrediQt-Cx can be easily employed to support decision making by clinicians and patients from north India region, through openly made available for access at http://prediqt.org.

The aim of this study was to quantify the effect of quadrivalent HPV (qHPV) vaccination on incidence of CIN2+ and CIN3+. A nationwide cohort of girls and young women resident in Sweden 2006-2013 and aged 13-29 (n = 1,333,691) was followed for vaccination and histologically confirmed high-grade cervical lesions. Data were collected using the Swedish nationwide healthcare registers. Poisson regression was used to calculate incidence rate ratios (IRRs) and vaccine effectiveness [(1-IRR)x100%] comparing fully vaccinated with unvaccinated individuals. IRRs were adjusted for attained age and parental education, and stratified on vaccination initiation age. Effectiveness against CIN2+ was 75% (IRR = 0.25, 95%CI = 0.18-0.35) for those initiating vaccination before age 17, and 46% (IRR = 0.54, 95%CI = 0.46-0.64) and 22% (IRR = 0.78, 95%CI = 0.65-0.93) for those initiating vaccination at ages 17-19, and at ages 20-29, respectively. Vaccine effectiveness against CIN3+ was similar to vaccine effectiveness against CIN2+. Results were robust for both women participating to the organized screening program and for women at prescreening ages. We show high effectiveness of qHPV vaccination on CIN2+ and CIN3+ lesions, with greater effectiveness observed in girls younger at vaccination initiation. Continued monitoring of impact of HPV vaccination in the population is needed in order to evaluate both long-term vaccine effectiveness and to evaluate whether the vaccination program achieves anticipated effects in prevention of invasive cervical cancer.

    The objective of this preliminary study was to determine whether quantitative ultrasound (QUS) can provide insight into, and characterization of, uterine cervical microstructure. Throughout pregnancy, cervical collagen reorganizes (from aligned and anisotropic to disorganized and isotropic) as the cervix changes in preparation for delivery. Premature changes in collagen are associated with premature birth in mammals. Because QUS is able to detect structural anisotropy/isotropy, we hypothesized that it may provide a means of noninvasively assessing cervical microstructure. Thorough study of cervical microstructure has been limited by lack of technology to detect small changes in collagen organization, which has in turn limited our ability to detect abnormal and/or premature changes in collagen that may lead to preterm birth. In order to determine whether QUS may be useful for detection of cervical microstructure, radiofrequency (rf) echo data were acquired from the cervices of human hysterectomy specimens (n = 10). The angle between the acoustic beam and tissue was used to assess anisotropic acoustic propagation by control of transmit/receive angles from -20 degrees to +20 degrees. The power spectrum of the echo signals from within a region of interest was computed in order to investigate the microstructure of the tissue. An identical analysis was performed on a homogeneous phantom with spherical scatterers for system calibration. Power spectra of backscattered rf from the cervix were 6 dB higher for normal (0 degree) than steered (+/- 20 degrees) beams. The spectral power for steered beams decreased monotonically (0.4 dB at +5 degrees to 3.6 dB at +20 degrees). The excess difference (compared to similar analysis for the phantom) in normally-incident (0 degree) versus steered beams is consistent with scattering from an aligned component of the cervical microstructure. Therefore, QUS appears to reliably identify an aligned component of cervical microstructure

    Objective To explore the histological subtypes of solitary pulmonary nodules (SPNs) of invasive adenocarcinoma and their clinical relevance. Methods A total of 188 patients with pathologically confirmed invasive adenocarcinoma in our hospital from January 2007 to December 2011 were enrolled in this study. In accordance with the new classification of lung adenocarcinoma, all the histological sections were reviewed and classified, and the clinical data were collected and analyzed. Results Of these 188 patients who had been initially diagnosed as SPNs of adenocarcinoma, there were 6 cases of lepidic predominant adenocarcinoma (LPA), 71 cases of acinar predominant adenocarcinoma (APA), 74 cases of papillary predominant adenocarcinoma (PPA), 15 cases of micorpapillary predominant adenocarcinoma (MPA), and 22 cases of solid predominant adenocarcinoma (SPA) with mucin production. The incidence of lymph node metastasis was 80.0% and 81.8% in MPA and SPA, respectively, which was significantly higher than those in LPA, APA, and PPA (all P<0.01). The incidence of LPA was 83.3% (5/6) in women, which was significantly higher than that in men (P=0.037). Conclusions According to the new classification, MPA and SPA have high incidence of lymph node metastasis. LPA is more likely to occur in women. Sub-typing of the lung adenocarcinoma based on the newest international classification criteria is helpful to identify the clinical features of this disease. PMID:24409363

    Adenocarcinoma is the most common histological type of lung carcinoma. Recently the histologic classification of adenocarcinomas in the lung was modified to better reflect biologic properties and prognosis. We reviewed the histology of all primary lung adenocarcinomas operated on in Iceland during a 20-year period and assessed the impact of histology on survival. This nationwide study included 285 patients (mean age 67 years, 57% female), who underwent resection in Iceland from 1991 to 2010. Tumors were reclassified according to the current IASLC/ATS/ERS classification system. Overall survival was estimated by the Kaplan-Meier method and Cox regression analysis used to evaluate prognostic factors of overall mortality. Acinar predominant adenocarcinoma was the most common histological subtype (46%) followed by solid-predominant (SPA) with mucin production comprised (23%). Non-invasive carcinomas were rare. A difference in survival between the histological adenocarcinoma subtypes was not seen (p = 0.32) and multivariate analysis showed that advanced stage and age predicted worse outcome, but histologic subtyping of adenocarcinoma did not. In this nation-wide study there was not a statistical difference in survival according to adenocarcinoma subtypes and the histological subtype did not predict mortality. Preinvasive and minimally invasive adenocarcinomas were rare. PMID:26957057

  6. How protective is cervical cancer screening against cervical cancer mortality in developing countries? The Colombian case

    PubMed Central

    2010-01-01

    Background Cervical cancer is one of the top causes of cancer morbidity and mortality in Colombia despite the existence of a national preventive program. Screening coverage with cervical cytology does not explain the lack of success of the program in reducing incidence and mortality rates by cervical cancer. To address this problem an ecological analysis, at department level, was carried out in Colombia to assess the relationship between cervical screening characteristics and cervical cancer mortality rates. Methods Mortality rates by cervical cancer were estimated at the department level for the period 2000-2005. Levels of mortality rates were compared to cervical screening coverage and other characteristics of the program. A Poisson regression was used to estimate the effect of different dimensions of program performance on mortality by cervical cancer. Results Screening coverage ranged from 28.7% to 65.6% by department but increases on this variable were not related to decreases in mortality rates. A significant reduction in mortality was found in departments where a higher proportion of women looked for medical advice when abnormal findings were reported in Pap smears. Geographic areas where a higher proportion of women lack health insurance had higher rates of mortality by cervical cancer. Conclusions These results suggest that coverage is not adequate to prevent mortality due to cervical cancer if women with abnormal results are not provided with adequate follow up and treatment. The role of different dimensions of health care such as insurance coverage, quality of care, and barriers for accessing health care needs to be evaluated and addressed in future studies.

    Cervical orthosis is used to immobilize the neck in various disorders such as trauma and post-operation. However, it is still uncertain how cervical orthosis restricts the degree of movement of the cervical spine during swallowing and how they affect swallowing physiology. The purpose of this study was to evaluate these issues using the Philadelphia(®) Collar. We conducted videofluorography of swallowing in 39 healthy subjects (23 men, 16 women; mean age of 34.3 years) with and without cervical orthosis. To compare the two conditions regarding the cervical spine motion, we determined the angular and positional changes of the occipital bone (C0) and each cervical vertebra (C1-C7) from the oral phase to the pharyngeal phase. Similarly, to compare swallowing physiology, we assessed the start and end times and the durations of soft palate elevation, rapid hyoid anterosuperior movement, epiglottis inversion, closure of the laryngeal vestibule, and pharyngoesophageal segment (PES) opening. Finally, we compared the transit times of contrast agent in the two conditions. The respective extensions of C1, C2, and C3 were 0.31°, 0.07°, and 0.05° (mean) with cervical orthosis, and the respective flexions of C1, C2, and C3 were 0.98°, 1.42°, and 0.85° (mean) without. These results suggested that cervical orthosis restricted the flexion of C1-C3. Analysis of swallowing physiology revealed that the average durations of hyoid anterosuperior elevation, epiglottic inversion, and PES opening were prolonged by 0.09, 0.19, and 0.05 s, respectively. In conclusion, the cervical orthosis restricted the movement of the cervical spine during swallowing and changed swallowing physiology. PMID:26607160

    Cancer represents a set of more than 100 diseases, including malignant tumors from different locations. Strategies inducing differentiation have had limited success in the treatment of established cancers. Marine sponges are a biological reservoir of bioactive molecules, especially lectins. Several animal and plant lectins were purified with antitumor activity, mitogenic, anti-inflammatory and antiviral, but there are few reports in the literature describing the mechanism of action of lectins purified from marine sponges to induce apoptosis in human tumor cells. In this work, a lectin purified from the marine sponge Cinachyrella apion (CaL) was evaluated with respect to its hemolytic, cytotoxic and antiproliferative properties, besides the ability to induce cell death in tumor cells. The antiproliferative activity of CaL was tested against HeLa, PC3 and 3T3 cell lines, with highest growth inhibition for HeLa, reducing cell growth at a dose dependent manner (0.5–10 µg/mL). Hemolytic activity and toxicity against peripheral blood cells were tested using the concentration of IC50 (10 µg/mL) for both trials and twice the IC50 for analysis in flow cytometry, indicating that CaL is not toxic to these cells. To assess the mechanism of cell death caused by CaL in HeLa cells, we performed flow cytometry and western blotting. Results showed that lectin probably induces cell death by apoptosis activation by pro-apoptotic protein Bax, promoting mitochondrial membrane permeabilization, cell cycle arrest in S phase and acting as both dependent and/or independent of caspases pathway. These results indicate the potential of CaL in studies of medicine for treating cancer. PMID:22690140

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

    Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction. PMID:24707411

We present a case of 86-year-old female with metastatic gall bladder adenocarcinoma diagnosed eight months back who presented with generalized fatigue and poor oral intake and was found to be hypercalcemic with elevated parathyroid hormone levels. Imaging with technetium 99 m sestamibi scintigraphy with dual phase, subtraction thyroid scan (dual isotope scintigraphy), magnetic resonance imaging and ultrasonography did not demonstrate any parathyroid lesion in normal or ectopic sites. We believe that the tumor cells were the source of ectopic parathyroid hormone secretion as we had excluded all the other possibilities with extensive combined imaging thereby increasing the sensitivity of our testing. We report the first case of metastatic gall bladder adenocarcinoma with paraneoplastic ectopic parathyroid hormone secretion. PMID:27081650

    Urachal Carcinoma (UC) is a rare malignancy of urinary bladder. It is usually found in adults in advanced stages because the tumour often grows outside the bladder without producing clinical symptoms. Most of the cases are mucinous, intestinal or signet ring cell adenocarcinoma and the diagnosis is usually made on biopsy. Radiographic images of this tumour may show characteristic features with a midline solid or cystic mass in the anterior wall of bladder associated with small calcification, which is considered as a pathognomonic sign for the diagnosis of UC. We report a case of UC in an adult, whose radiographic images suggested an urachal tumour and Fine Needle Aspiration (FNA) cytology revealed an adenocarcinoma. Laparoscopic partial cystectomy with umbilectomy and pelvic node dissection was done without further histopathological confirmation. Surgical intervention of UC on the basis of FNA diagnosis has not been reported in the literature. PMID:27190817

    We are presenting an elderly Caucasian woman who was admitted to our hospital for severe lower back pain and scapular pain for 8 days. She had a history of spinal stenosis and we believed this was the aetiology of her pain. However, her pain was not subsiding and hence an MRI spine was performed. It revealed spinal stenosis and abnormal signal in the lower thoracic and lumbar vertebrae. Hence a bone biopsy was performed that came back as metastatic adenocarcinoma. She underwent a bone scan and revealed diffuse disease in thoracic, lumbar, sacral spine as well as third and 10th ribs. Her CT chest/abdomen/pelvis revealed no primary tumour. A mass was detected on her colonscopy, and pathology revealed adenocarcinoma. She underwent palliative radiation and one cycle of chemotherapy. She was discharged to home hospice care. It is very rare to have osseous metastases as the only manifestation of colon cancer. PMID:23861273

    Synopsis The past few years have brought new advances in our understanding of the molecular mechanisms underlying the development of Barrett’s esophagus and esophageal adenocarcinoma. Although knowledge of the genetic basis for these conditions has not yet translated into clinically useful biomarkers, the current pace of biomedical discovery holds endless possibilities for molecular medicine to improve the diagnosis and management of patients with these conditions. This article provides a useful conceptual basis for understanding the molecular events involved in the making of Barrett’s metaplasia and in its neoplastic progression and provides a rationale for evaluating studies on the application of molecular medicine to the diagnosis and management of patients with Barrett’s esophagus and esophageal adenocarcinoma.

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Histologically, the findings of a papillary pattern of poorly differentiated, mucicarmine-staining cells enclosing gland-like spaces, and the absence of pseudorosettes, melanin, mesenchymal and peripheral neural elements supports an epithelial origin of this tumor. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy. Careful long-term head and neck surveillance is mandatory if early aggressive management of these extremely lethal tumors is to be successful.

    A 17-yr-old Western Hognose snake (Heterodon nasicus) presented with a prominent midcoelomic swelling. Surgical exploration revealed a large, multicystic, irregular, tan, and firm mass grossly effacing the splenopancreas. The mass was subsequently removed. Histologically, the mass was composed of tubules of columnar to flattened neoplastic cells with an abundant stroma and moderate cellular atypia consistent with a scirrhous adenocarcinoma, likely ductal in origin, given the location of the neoplastic mass. Bloodwork revealed anemia, monocytosis, marked hypercalcemia, and, postoperatively, persistent hyperglycemia. After postoperative recovery, the snake was diagnosed with iatrogenically induced diabetes mellitus and exocrine pancreatic insufficiency. Due to the inability to clinically control the diabetes mellitus and exocrine pancreatic insufficiency and when additional palpable masses were noted, the snake was euthanatized. Necropsy and histopathologic examination confirmed metastasis of the previously removed adenocarcinoma to the liver, right kidney, and large intestine. PMID:20597225

    Over recent decades we have witnessed a shift in the anatomical distribution of gastric cancer (GC), which increasingly originates from the proximal stomach near the junction with the oesophagus. In parallel, there has been a dramatic rise in the incidence of oesophageal adenocarcinoma (OAC) in the lower oesophagus, which is associated with antecedent Barrett oesophagus (BO). In this context, there has been uncertainty regarding the characterization of adenocarcinomas spanning the area from the lower oesophagus to the distal stomach. Most relevant to this discussion is the distinction, if any, between OAC and intestinal-type GC of the proximal stomach. It is therefore timely to review our current understanding of OAC and intestinal-type GC, integrating advances from cell-of-origin studies and comprehensive genomic alteration analyses, ultimately enabling better insight into the relationship between these two cancers.

    ST-segment-elevation myocardial infarction is a leading cause of cardiovascular morbidity and death. We describe the case of a 51-year-old woman with advanced adenocarcinoma of the lung who presented with ST-segment elevation in the presence of an extracardiac lung mass but no objective evidence of myocardial ischemia or pericardial involvement. After the patient died of hypoxic respiratory failure, autopsy findings confirmed normal-appearing pericardium and myocardium, and mild-to-moderate atherosclerosis in the coronary arteries. A 4.5 × 4-cm extracardiac left hilar lung mass was confirmed to be poorly differentiated adenocarcinoma of the lung adjacent to the myocardium. The persistent current of injury that had been detected electrocardiographically was thought to occur from direct myocardial compression. ST-segment elevations secondary to direct mass contact on the myocardium should be considered in patients who have a malignancy and ST-segment elevation. PMID:26413024

    A 29-year-old woman had undergone gastrocystoplasty with Mitrofanoff appendicovesicostomy for urethral trauma at 9 years of age. Since then, she was being followed up for performing clean intermittent self-catheterization at regular intervals. Twenty years after the surgery, she presented with gross hematuria. Ultrasonographic findings revealed bilateral hydronephrosis. Cystoscopy and computed tomography (CT) revealed invasive bladder cancer with pelvic lymph node metastases. A biopsy confirmed the diagnosis of adenocarcinoma with signet ring cell carcinoma. Subsequently, neo-adjuvant combination chemotherapy with TS-1 and cisplatin (CDDP) was initiated, which was followed by open radical cystectomy with extended pelvic lymphadenectomy. The tumor was found to infiltrate from the anastomotic site into the entire native bladder and histopathological diagnosis was muscle invasive adenocarcinoma with neuroendocrine differentiation and lymph node metastasis (ypT3bN2). TS-1 was continued as adjuvant chemotherapy and the patient did not have any evidence of recurrence for 12 months postoperatively. PMID:26932334

Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases. PMID:27446469

    Prostate adenocarcinoma can manifest as a fairly indolent tumor or as a very aggressive cancer with significant invasive and metastatic potential. Common metastatic sites include bone, liver, lymph nodes, and adrenal glands. Dermatologic manifestations are rare. We present a case of a man who presented with breast skin changes that mimicked inflammatory breast carcinoma with specialized testing ultimately giving a diagnosis of metastatic prostatic adenocarcinoma. A 78-year-old man presented with left breast redness and swelling. Examination revealed an erythematous rash with subcutaneous edema over the left hemithoracic area. A breast ultrasound showed no focal mass, and a breast core biopsy had no evidence of tumor. A skin biopsy showed metastatic carcinoma in dermal lymphatics, and the tumor was found to have no estrogen or progesterone receptors or HER2 expression. Computed tomography scans, positron emission tomography, and a nuclear bone scan revealed widespread skeletal metastases. The patient received a 3-month course of capecitabine and cyclophosphamide with no improvement in his skin lesions. Subsequent immunohistochemical staining on the tumor specimen was positive for prostate-specific antigen (PSA) and alpha-methyl-CoA-racemase, confirming a diagnosis of metastatic prostatic adenocarcinoma. He received leuprolide and bicalutamide and demonstrated significant improvement with near-complete resolution of his skin lesions and a decrease in his PSA level. Prostatic adenocarcinoma presenting initially as a breast malignancy is a rarely recognizable clinical event. Undoubtedly, increased awareness and recognition of the rare entity described herein will allow for the prompt initiation of specific therapies, which might be of benefit to many patients.

    Dedifferentiated endometrioid adenocarcinoma (DEAC) of the uterus or ovary is characterized by the coexistence of low-grade endometrioid adenocarcinoma and an undifferentiated carcinoma (UC) with solid sheets of medium-sized monotonous epithelial cells. This admixed carcinoma has not been widely recognized, because the solid areas of UC have usually been misdiagnosed as a solid form of FIGO grade 3 endometrioid adenocarcinoma. These tumors have been shown to be clinically aggressive; therefore, accurate diagnosis is necessary for proper patient management. We reviewed our experience with DEACs and compared them with grade 3 endometrioid carcinomas regarding their clinicopathologic, morphologic, and immunohistochemical features. Our results indicate that DEACs are clinically aggressive tumors presented at advanced stages with vascular invasions in 73% and lymph node metastases in 46%. Thirty-eight percent of cases also showed distal metastases. Clinical follow-up data revealed that all patients had either recurrent or metastatic diseases within 3 years of diagnosis, except 1 patient who remained disease free for 3 years after diagnosis. Morphologically, UC components of DEACs were composed of diffuse sheets/solid nests of medium-sized epithelial cells with scant to moderate cytoplasm, uniform vesicular nuclei, and inconspicuous nucleoli. Although UC components of DEACs are variably positive for cytokeratin, EMA, and ER, they are mostly negative for PAX8, except 1 case. Instead, well-differentiated components of DEACs and solid grade 3 endometrioid carcinoma retained all these markers. Our results indicate that DEACs exhibit significantly different clinicopathologic features from grade 3 endometrioid adenocarcinoma, and a combination of immunohistochemical stains can be helpful to differentiate them from each other.

    We report a case of adenocarcinoma of the pigmented ciliary epithelium arising in a phthisical eye. A 92-year-old man who initially presented with severe ocular pain had calcification extending from the posterior pole to ciliary body on B-scan ultrasonography to a degree not previously reported. We highlight the importance of screening for intraocular neoplasms in adults with a long-standing phthisical eye. PMID:26597037

    Secondary or acquired phimosis usually occurs as part of a benign disease. We present a case of secondary phimosis caused by metastasis from a newly diagnosed oesophageal adenocarcinoma. The patient presented with clinical suspicion of infection in the preputial space, but histopathology revealed dilated lymphatic vessels with peripheral embolisms of epithelial tumour cells. This case report emphasizes the importance of establishing the cause of secondary phimosis by histopath-ological examination for possible malignancy. PMID:25822817

    Since hyperinsulinaemia may promote obesity-linked cancers, we compared type 2 diabetes prevalence among oesophageal adenocarcinoma (OAC) patients and population controls. Diabetes increased the risk of OAC (adjusted odds ratio 1.59, 95% confidence interval (CI) 1.04–2.43), although the risk was attenuated after further adjusting for body mass index (1.32, 95% CI 0.85–2.05).

    Ectopic production of adrenocorticotrophic hormone (ACTH) by malignant neoplasms is a well recognised cause of Cushing's syndrome but is extremely rare in ovarian carcinoma. A patient who underwent surgery for ovarian carcinoma followed by a course of chemotherapy is reported. The tumour was a bilateral moderately differentiated endometrioid adenocarcinoma and contained numerous chromogranin immunoreactive endocrine cells as well as small foci of ACTH immunoreactivity. She subsequently presented with Cushing's syndrome in association with extensive pelvic recurrence of the tumour. Images PMID:7962637

    ABSTRACT We report a rare case of sinonasal intestinal-type adenocarcinoma in the nasal cavity. A 31-year old man presented with headache and epistaxis. We identified a malignant tumour, which is a rare pathology, with detailed physical examination, anterior rhinoscopy, computed tomography scan, magnetic resonance imaging and histopathologic examination. Endoscopic excision of the tumour was performed. After three years of follow-up of the patient in our clinic, there was no sign of any recurrence. PMID:25803391

    Penile metastases are rare in occurrence and are usually secondary to other genitourinary primary tumours. It is a debilitating near terminal condition at presentation with a dismal prognosis and poor survival rates. Supportive and palliative care is generally recommended to improve the quality of life of patients. We present a case of penile metastases in a 74-year-old male patient with prostatic adenocarcinoma in association with multiple skeletal metastases. PMID:26500946

    Metastasis to the penis is an uncommon occurrence, with only about 370 cases reported in the literature to date. The majority of the primary tumors are genitourinary in origin. We report on a patient with undiagnosed disseminated rectal adenocarcinoma, who first presented with lesions of the corporal bodies. A review of the literature indicates that corporeal metastasis as an initial presentation of malignancy is an extremely rare occurrence and carries a very poor prognosis. PMID:26435874

    Objectives To investigate cancer risk, particularly oesophageal cancer, among male upstream petroleum workers offshore potentially exposed to various carcinogenic agents. Methods Using the Norwegian Registry of Employers and Employees, 24 765 male offshore workers registered from 1981 to 2003 was compared with 283 002 male referents from the general working population matched by age and community of residence. The historical cohort was linked to the Cancer Registry of Norway and the Norwegian Cause of Death Registry. Results Male offshore workers had excess risk of oesophageal cancer (RR 2.6, 95% CI 1.4 to 4.8) compared with the reference population. Only the adenocarcinoma type had a significantly increased risk (RR 2.7, 95% CI 1.0 to 7.0), mainly because of an increased risk among upstream operators (RR 4.3, 95% CI 1.3 to 14.5). Upstream operators did not have significant excess of respiratory system or colon cancer or mortality from any other lifestyle-related diseases investigated. Conclusion We found a fourfold excess risk of oesophageal adenocarcinoma among male workers assumed to have had the most extensive contact with crude oil. Due to the small number of cases, and a lack of detailed data on occupational exposure and lifestyle factors associated with oesophageal adenocarcinoma, the results must be interpreted with caution. Nevertheless, given the low risk of lifestyle-related cancers and causes of death in this working group, the results add to the observations in other low-powered studies on oesophageal cancer, further suggesting that factors related to the petroleum stream or carcinogenic agents used in the production process might be associated with risk of oesophageal adenocarcinoma.

    Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related death and current therapeutic strategies are often unsatisfactory. Identification and development of more efficacious therapies is urgently needed. Immunotherapy offered encouraging results in preclinical models during the last decades, and several clinical trials have explored its therapeutic application in PDAC. The aim of this review is to summarize the results of clinical trials conducted to evaluate the future perspective of immunotherapy in the treatment of PDAC. PMID:26361407
