    Full Text Available Adenosquamous cell carcinoma of the cervix is a rare form of cancer of the cervix. Because of the small number of observations adenosquamous cell carcinoma of the cervix remains poorly understood disease, although the first mention of it dates back to 1956, when A. Glucksmann, and C.D. Cherry first described of mixed carcinoma (adenoacanthoma of the uterine cervix.

    Small cell carcinoma of the uterine cervix accounts for 1-3% of all cervix cancers. It is an aggressive disease with a poor prognosis. To date, no effective treatment protocol has been determined. Surgery, radiotherapy, and chemotherapy have been used either alone or in combination. Recent data suggests that survival in patients with early staged small cell carcinoma of the cervix is better with surgery combined with chemo-radiotherapy. Here, we presented two patients with stage IB1 small cell carcinoma of the uterine cervix. For both patients, definitive surgery was performed with pelvic and para-aortic lymphadenectomy. Subsequently, they were treated with pelvic external radiotherapy and high-dose-rate intracavitary brachytherapy with concurrent cisplatin based chemotherapy. They were alive with no evidence of disease at 91 and 65 months, respectively.

    Small cell neuroendocrine carcinoma of the uterine cervix is a rare primary neoplasm, accounting for less than 5% of all uterine cervical cancers. The tumor is known to have an aggressive behavior and poor prognosis. In this article, we present the MRI findings of 5 cases of pathologically-proven small cell neuroendocrine carcinoma of the uterine cervix, including diffusion-weighted images.

    Full Text Available Abstract Introduction Pulmonary metastasis presenting as lymphangitic carcinomatosis arising from squamous cell carcinoma (SCC of the cervix is a rare event. Poorly represented in the literature, this event is associated with a difficulty in accurate diagnosis, b grave prognosis, and the c lack of recognized predisposing risk factors. Case Report A 50 year-old female presented at our practice with a three-month history of a productive cough associated with dyspnoea and shortness of breath. A chest x-ray and computed tomography (CT scan revealed multiple bilateral patchy areas with subsegmental atelectasis in both lungs which was investigated with a bronchoscopy, left thoracoscopy, and a left lung biopsy. Pathological examination of the wedge biopsy of the left upper lobe revealed neoplastic sheets of cell disturbed along the septal vessels, perivascular/peribronchial lymphatics, and the subpleural lymphatics. This lymphangitic carcinomatosis was confirmed to be metastatic from SCC of the cervix that had been diagnosed and treated two years ago. She was treated with systemic Carbo/Taxol chemotherapy and corticosteroids as a palliative measure. Despite temporary improvement, she died 13 months later. Conclusion Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic SCC of the cervix. As clinical presentations including radiographic imaging mimics other pulmonary entities, accurate diagnosis remains a challenge. Increased clinical awareness of such patterns of metastases in cervical cancer supported by accurate pathological diagnosis is imperative to guide appropriate therapy in these patients.

    2013-01-01

    Full Text Available Background: Papillary squamotransitional cell carcinoma (PSCC is a distinctive subcategory of squamous cell carcinoma of the uterine cervix. It has a propensity for local recurrence and late metastasis. Histologically, it can be misinterpreted as transitional cell carcinoma, or other papillary lesions of the cervix including squamous papilloma, verrucous carcinoma or cervical intraepithelial neoplasia grade 3 with papillary configuration. Materials and Methods: Nine cases of PSCC of the uterine cervix were diagnosed on a cervical biopsy specimen on routine hematoxylin and eosin (H and E stained sections. Their clinic-morphological features were analyzed. The cases were further evaluated immunohistochemically by cytokeratin 7 (CK7, cytokeratin 20 (CK20, p53 and Ki-67. Results: The patients ranged in age from 35 years to 75 years; with abnormal uterine bleeding being the most common clinical presentation. All the cases showed papillary architecture with fibrovascular cores lined by multilayered atypical epithelium. Three cell types were observed: Clear, intermediate and basaloid. Stromal invasion was seen in five cases, whereas in the remaining four cases, the biopsy specimen was too superficial to definitely assess invasion. Immunohistochemically, eight cases were CK7 + /CK20 - and one case was CK7 - /CK20 - . All nine cases showed nuclear accumulation of mutant p53. Moderate and high proliferative activity was observed in two and seven cases, respectively. Five of patients for whom follow-up information was available underwent radical hysterectomy and two of them were disease free 18 months following treatment. Conclusion: PSCC of the uterine cervix are a clinicomorphologically distinct group of cervical lesions that display a morphologic spectrum. They are potentially aggressive malignant tumors that should be distinguished from transitional cell carcinoma and other papillary lesions of the uterine cervix.

  7. Progress in Diagnosis and Treatment of Small Cell Carcinoma of the Cervix

    Small cell carcinoma of the cervix (SCCC) belongs to the neuroendocrine carcinomas, and it is a rare gynecological tumor of high-potential malignancy. It has a poorer prognosis compared to cervical squamous cancer or adenocarcinoma, and the therapeutic regimen of the disease differs. Diagnosis is based on pathomorphological characteristics, i.e., the small and round cancer cells (oat cell) which are uniform in shape and size, with the immunohistochemical marker helpful for diagnosis. Combined therapy is first recommended. Postoperative chemotherapy with platinum/etoposide (PE), vincristine/adriamycin/cyclophosphamide (VAC) and taxel/carboplatin (TP) can markedly improve the prognosis of early SCCC patients.

    Full Text Available Definitive cytomorphologic diagnosis of small cell carcinoma of the uterine cervix is possible but can be challenging in routine cervicovaginal cancer screening specimens. Several small series of reported cases of cervical small cell carcinoma have shown this uncommon malignancy to represent fewer than 2% of all invasive cervical cancers. This tumor type is associated with poor prognosis and rapid disease progression and can develop to an advanced stage in the interval between screening visits. Only rare case reports of small cell carcinoma arising in gravid cervices are known. In the current case a 29-year-old, gravida 6, para 2, pregnant (10-week gestation female presented with postcoital bleeding. A definitive diagnosis of small cell carcinoma of the cervix was made possible by liquid based Pap testing with ancillary cell block preparation allowing for immunocytochemical characterization of the lesional cell population.

    2014-08-01

    Glassy cell carcinoma (GCC) is a histologically aggressive subtype of cervical cancer with rapid growth and early metastases. The prognosis for patients with GCC is poor. This article reviews the literature pertinent to the epidemiology, cytology, pathology, immunohistochemistry, treatment and prognosis of GCC. MEDLINE (PubMed) was searched for all articles or abstracts on patients diagnosed with GCC published (in English) since the original definition by Glucksmann and Cherry, Cancer 1956;9:971. Accurate diagnosis of GCC enables implementation of the correct treatment strategy. Early-stage GCC should be treated with hysterectomy and pelvic lymph node dissection, with adjuvant radiochemotherapy if at least one intermediate or high risk factor for cervical cancer is present. Advanced GCC should be treated with neoadjuvant radiochemotherapy or chemotherapy with the aim of making the disease operable. There is a need for retrospective evaluation of GCC treatment from several centres to explore knowledge about this rare entity. Future studies should explore the role of targeted therapies and the most efficient chemotherapy regimen for the management of GCC.

    Full Text Available Glassy cell carcinoma is a poorly differentiated variant of adenosquamous carcinoma of the cervix associated with an aggressive course and a poor prognosis. We present three cases of glassy cell carcinoma of the cervix. Patients presented with a cervical growth which was biopsied. Histology the tumours showed nests of cells with a granular or clear cytoplasm, displaying marked pleomorphism and mitoses. Stroma showed an eosinophilic infiltrate. Two tumours showed a pure glassy cell pattern and one showed glandular differentiation with intracellular and extracellular mucin. Patients were treated with a combination of surgery, radiotherapy and chemotherapy but showed a poor response. Two patients died of the disease of pelvic or distant metastases within two years of diagnosis and one was lost to follow up. Although glassy cell carcinoma runs an aggressive clinical course, an early diagnosis may help in a more effective management and offer a better prognosis.

    In the present study, an attempt was made to identify genes involved in radiation response in cervix carcinoma. Differential display technique was used to study the expression profiles of tumour biopsy samples obtained from patients, responding and not responding to treatment. The samples were obtained prior to radiotherapy and subsequent to treatment with Tele-radiation at 10 Gray (Gy). One of the differentially expressed cDNAs, when sequenced was identified to be CDC27. Immuno-histochemical analysis of pre- and post-treated tumour samples from fifteen patients showed the downregulation of expression of CDC27 protein in seven patients. Down-regulation was associated with poorer response to radiotherapy. Cervical cancer cell lines SiHa and C33A were irradiated and their nuclei were stained for expression of CDC27 and analyzed using fluorescent-activated cell sorting (FACS). Down-regulation of CDC27 protein in the irradiated SiHa cell line was associated with greater survival fraction, compared to the irradiated C33A cell line, which had only slight fall in the level of CDC27 protein. This is the first study to suggest a role for CDC27 in radiation response. However, a larger cohort is needed to further confirm the value of CDC27 protein as a predictive marker, for radiation response in cervix cancer.

    Objective: to compare survival and toxicity of three different treatments for stage IIIB cervix cancer: low-dose-rate (LDR), high-dose-rate (HDR) brachytherapy and association of HDR and chemotherapy. Methods: between 1985 and 2005, 230 patients with FIGO stage IIIB squamous cell carcinoma of the uterine cervix received 4-field pelvic teletherapy at doses between 40 and 50.4 Gy, with a different complementation in each group. The LDRB group, with 42 patients, received one or two insertions of LDR, with Cesium-137, in a total dose of 80 to 100Gy at point A. The HDR group, 155 patients received HDR in 4 weekly 7 Gy fractions and 9 Gy to 14.4 Gy applied to the involved parametria. The CHT group, 33 patients, were given the same treatment as the HDR group and received 5 or 6 weekly cycles of cisplatin, 40 mg per m2. Results: the five-year progression-free survival (PFS) was 60% for the HDR group and 45% for the LDR group, and the two-year PFS for the CHT group was 65% (p = 0.02). The five-year Overall Survival (OS) was 65% for the HDR group and 49% for the LDR group. The two-year OS was 86% for the CHT group (p 0.02). Rectum toxicity grade II was 7% for the LDR group, 4% for the HDR group and 7% for the CHT group that had one case of rectum toxicity grade IV. Conclusion: patients that received HDR had better OS and PFS. The Chemotherapy-HDR association showed no benefit when compared to HDR only. Toxicity rates showed no difference between the three groups. (author)

    A number of genes and their products are induced early or late following exposure of cells to ionizing radiation. These radiation-induced genes have various effects of irradiated cells and tissues. Suppression subtractive hybridization (SSH) based on PCR was used to identify the differentially expressed genes by radiation in cervix carcinoma cells. Total RNA and poly (A){sup +} mRNA were isolated from irradiated and non-irradiated HeLa cells. Forward-and reverse-subtracted cDNA libraries were constructed using SSH. Eighty-eight clones of each were used to randomly select differentially expressed genes using reverse Northern blotting (dot blot analysis). Northern blotting was used to verify the screened genes. Of the 176 clones, 10 genes in the forward-subtracted library and 9 genes in the reverse-subtracted library were identified as differentially expressed radiation-induced genes by PCR-select differential screening. Three clones from the forward-subtracted library were confirmed by Northern blotting, and showed increased expression in a dose-dependent manner, including a telomerase catalytic subunit and sodium channel-like protein gene, and an ESTs (expressed sequence tags) gene. We identified differentially expressed radiation-induced genes with low-abundance genes with SSH, but further characterization of theses genes are necessary to clarify the biological functions of them.

    Skeletal metastasis in carcinoma cervix occurs in about 0.8-23% of cases. These lesions are usually radiographically lytic. Very few cases of metastases to the skull have been identiifed, about 5 cases to the best of our knowledge. We present a case of adenosquamous cell carcinoma of cervix with fat attenuating skull metastases in a 38-year-old lady that is not reported till date. The lesion was lytic, expansile and with negative attenuation of -15 to -30 Hounsifeld units corresponding to fat.Metastases must be included in the differentials of scalp lesions. A history of recent onset of swelling and associated lytic areas in calvarium on contrast enhanced computed tomography with multiplicity can give a clue to metastatic nature of disease.

    Full Text Available Cervical carcinoma is the most common malignancy of the female genital tract and represents the second most common malignancy in women worldwide. Histologically 85 to 90% of cervical cancers are squamous cell carcinoma. Osteoclastic giant cell rich squamous cell carcinoma is an unusual histological variant of which only 4 cases have been reported. We present the case of a 49-year-old woman with a 6-month history of irregular vaginal bleeding. Examination revealed a 2.7 cm polypoid mass in the anterior lip of the uterine cervix. The patient underwent hysterectomy with bilateral salpingo-oophorectomy. Microscopically the tumor was composed of infiltrative nests of poorly differentiated nonkeratinizing squamous cell carcinoma. Interspersed in between these tumor cells were numerous osteoclastic giant cells with abundant eosinophilic cytoplasm devoid of nuclear atypia, hyperchromatism, or mitotic activity. Immunohistochemistry was performed; CK and P63 were strongly positive in the squamous component and negative in the osteoclastic giant cells, while CD68 and Vimentin were strongly positive in the giant cell population and negative in the squamous component. The patient received chemo- and radiotherapy for recurrent disease identified 3 months later on a follow-up CT scan; 7 months after the surgical procedure the patient is clinically and radiologically disease-free.

    Full Text Available Background: Pulmonary lymphangitic carcinomatosis (LC secondary to cervical squamous cell carcinoma (SCC is an uncommon cause of diffuse infiltrative lung disease. Its reported incidence is quiet low. Materials and Methods: Fifty cases of cervical carcinoma were studied from 2005 to 2014. There was only one case of squamous cell carcinoma cervix that developed pulmonary lymphangitic carcinomatosis subsequently. Clinical manifestations of LC such as dyspnea and non-productive cough can mimic with clinical picture of pneumonia, pneumonitis, pulmonary embolism, congestive heart failure, asthma, and sarcoidosis and thus can be a diagnostic dilemma for treating physician. A review of world literature was also done to examine all the reported cases of cervical carcinoma which presented as pulmonary lymphangitic carcinomatosis. A few cases have been reported so far. Concussion: Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic Squamous Cell Carcinoma (SCC of the cervix and is associated with a poor prognosis. Increased clinical alertness of such patterns of metastases in cervical cancer along with accurate pathological diagnosis is compulsory to guide proper therapy in these patients.

    Lowe, D G

    1988-04-01

    Massive local eosinophilia of 100 or more eosinophils per high power field was found in 3.2% cases of invasive carcinoma of the cervix. The prevalence, length of history before presentation to surgery and histological features were similar in patients from Great Britain and Malawi, but in both populations the mean age at diagnosis was lower than in patients with cervical carcinomas without tissue eosinophilia. In some of the tumours, the malignant cells were very difficult to find because of the eosinophil infiltrate, and misinterpretation as an inflammatory lesion was possible. In the absence of circulating eosinophilia, cervical carcinomas with massive eosinophilia were found to have a better prognosis than tumours without. Five patients had circulating eosinophilia as well as local tumour eosinophil infiltration, and each of them had extensive tumour spread.

    The differentiation between cervical intraepithelial neoplasia 3 (CIN 3) and early squamous cell carcinoma (SCC) of the cervix may be difficult in certain situations. Identification of invasion beyond the basement membrane is the gold standard for the diagnosis of the latter. The objective of this study was to determine whether the use of Ki-67 and p53 could help in solving the above dilemma. This was a retrospective study on 61 cases of cervical neoplasms comprising of 25 cases of CIN 3 and 36 SCC. All cases were evaluated by immunohistochemistry using Ki-67 and p53 monoclonal antibodies. Results showed that the differences of Ki-67 and p53 expression between CIN 3 and SCC were statistically significant. In conclusion, Ki-67 and p53 may serve as helpful adjuncts to routinely-stained histological sections in differentiating between CIN 3 and SCC.

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

    Full Text Available Abstract Background It is well known that a persistent infection with high-risk human papillomavirus (hrHPV is causally involved in the development of squamous cell carcinomas of the uterine cervix (CxSCCs and a subset of SCCs of the head and neck (HNSCCs. The latter differ from hrHPV-negative HNSCCs at the clinical and molecular level. Methods To determine whether hrHPV-associated SCCs arising from different organs have specific chromosomal alterations in common, we compared genome-wide chromosomal profiles of 10 CxSCCs (all hrHPV-positive with 12 hrHPV-positive HNSCCs and 30 hrHPV-negative HNSCCs. Potential organ-specific alterations and alterations shared by SCCs in general were investigated as well. Results Unsupervised hierarchical clustering resulted in one mainly hrHPV-positive and one mainly hrHPV-negative cluster. Interestingly, loss at 13q and gain at 20q were frequent in HPV-positive carcinomas of both origins, but uncommon in hrHPV-negative HNSCCs, indicating that these alterations are associated with hrHPV-mediated carcinogenesis. Within the group of hrHPV-positive carcinomas, HNSCCs more frequently showed gains of multiple regions at 8q whereas CxSCCs more often showed loss at 17p. Finally, gains at 3q24-29 and losses at 11q22.3-25 were frequent (>50% in all sample groups. Conclusion In this study hrHPV-specific, organ-specific, and pan-SCC chromosomal alterations were identified. The existence of hrHPV-specific alterations in SCCs of different anatomical origin, suggests that these alterations are crucial for hrHPV-mediated carcinogenesis.

    Full Text Available The association of human papilloma virus (HPV infection and cervical intraepithelial neoplasia (CIN is well recognized. Interaction of HPV oncogenic proteins with cellular regulatory proteins leads to up regulation of p16 INK4A , a CDK inhibitor, which is a biomarker for HPV infection. We investigated p16 expression in CIN and invasive squamous cell carcinoma (SCC which has not been reported in the Indian population previously. Materials and Methods: Retrospective analysis of 100 cases with 20 cases each of histologically normal cervical epithelium, CIN1, 2, 3 and invasive SCC for p16 expression was performed by immunohistochemistry using commercially available mouse monoclonal antibody to p16 (clone 6H12. Statistical Analysis: For differences in expression among groups, statistical analysis was carried out using ANOVA and post hoc test of Scheffe. Results: p16 immunoreactivity was found to be both nuclear and/or cytoplasmic. The normal cervical epithelium was predominantly negative for p16 (18/20. There was a progressive increase of p16 expression with the grade of CIN. In CIN 1, two cases (20% showed nuclear and nucleocytoplasmic positivity respectively. In contrast, diffuse strong nuclear or nucleocytoplasmic expression was observed in 45 and 55% cases of CIN 2 and CIN 3 respectively. All except one squamous cell carcinoma stained strongly positive for p16. The difference in expression between CIN 2/3 and SCC versus normal cervix was found highly significant (p is equal to 0.008 and p less than 0.001. Conclusions: p16 expression correlates excellently with the grade of CIN and is a sensitive marker of cervical intraepithelial neoplasia.

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

    PURPOSE: Although cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) are both caused by human papillomavirus (HPV) infection, they differ in cofactors such as cigarette smoking. We assessed whether these cofactor differences translate into differences in second cancer risk. PATIENTS...... AND METHODS: We assessed second cancer risk among 85,109 cervical SCC and 10,280 AC survivors reported to population-based cancer registries in Denmark, Finland, Norway, Sweden, and the United States. Risks compared to the general population were assessed using standardized incidence ratios (SIR). RESULTS......: Overall cancer risk was significantly increased among both cervical SCC survivors (n = 10,559 second cancers; SIR, 1.31; 95% CI, 1.29 to 1.34) and AC survivors (n = 920 second cancers; SIR, 1.29; 95% CI, 1.22 to 1.38). Risks of HPV-related and radiation-related cancers were increased to a similar extent...

    Cervical cancer can be classified into two histological types: squamous cell carcinoma (SCA) and adenocarcinoma (ACA). Reportedly ACA has poorer prognoses, metastasizes more easily to lymph nodes, and is more resistant to radiotherapy than SCA. To clarify the cause of characteristic differences between these histological types, we examined the expressions of apoptosis inhibiting and tumor-invasion related factors in both histological types. We reviewed the 34 cases of cervical cancer (17 ACA, 17 SCA) that had surgery as their initial treatment at Osaka City University Medical School Hospital between 1996 and 2001. The differences of survivin, and matrix metalloproteinase (MMP-2, and MMP-7) expressions between both histological types were immunohistochemically assayed, and the correlation between the expression of each protein and clinicopathological characteristics was analyzed. Survivin was expressed significantly stronger in ACA cases (p=0.035). The number of patients who expressed MMP-2 and MMP-7 simultaneously was significantly higher in SCA cases (p=0.039). MMP-2 and MMP-7 had tendencies to be expressed stronger in SCA (p=0.057 and p=0.084, respectively). These results suggest that the differences of the expression of survivin (an apoptosis inhibiting factor), MMP-2, and MMP-7 (tumor-invasion related factors) between ACA and SCA were causes of the characteristic differences between the two histological types.

    Distinguishing invasive high-grade urothelial carcinoma (UC) from other carcinomas occurring in the genitourinary tract may be difficult. The differential diagnosis includes high-grade prostatic adenocarcinoma, spread from an anal squamous cell carcinoma (SCC), or spread from a uterine cervical SCC. In terms of metastatic UC, the most common problem is differentiating spread of UC to the lung from a primary pulmonary SCC. Immunohistochemical analysis (IHC) for GATA binding protein 3 (GATA3), thrombomodulin (THROMBO), and uroplakin III was performed on a tissue microarray (TMA) containing 35 cases of invasive high-grade UC. GATA3 IHC was also performed on TMAs containing 38 high-grade (Gleason score ≥8) prostatic adenocarcinomas, representative tissue sections from 15 invasive anal SCCs, representative tissue sections from 19 invasive cervical SCCs, and TMAs with 12 invasive cervical carcinomas of the cervix [SCC (n=10), SCC with neuroendocrine features (n=1), and adenosquamous carcinoma (n=1)]. In addition, GATA3 IHC was performed on representative tissue sections from 15 pulmonary UC metastases and a TMA with 25 SCCs of the lung and 5 pulmonary non-small cell carcinomas with squamous features. GATA3, THROMBO, and uroplakin III were positive in 28 (80%), 22 (63%), and 21 (60%) cases of high-grade UC, respectively. All cases of GATA3-positive staining were nonfocal; 25 (89%) cases demonstrated moderate to strong staining, and 3 (11%) demonstrated weak staining. Of the 7 cases that failed to express GATA3, 5 were positive for THROMBO and/or uroplakin III, whereas 2 were negative for all 3 markers. None of the 38 high-grade prostatic adenocarcinomas was positive for GATA3. Weak GATA3 staining was present in occasional basal cells of benign prostate glands, in a few benign atrophic glands, and in urothelial metaplasia. Of the 15 cases of anal SCCs, 2 (7%) cases showed focal weak staining, and 1 (3%) showed focal moderate staining. Weak staining was also rarely

    Uterine papillary serous carcinoma (UPSC) is a clinically aggressive and morphologically distinctive variant of endometrial carcinoma that has been recognized recently as a distinct entity. The association between radiation therapy (RT) and UPSC is rarely described in the literature. We describe the clinicopathologic features of a 71-year-old patient with UPSC that developed 15 years after radiation therapy for squamous cell carcinoma of cervix, stage IIB. In the subtotal hysterectomy specimen the endometrium was irregular with multifocally raised masses. Microscopically, the tumor was composed of high-grade papillary serous carcinoma focally admixed with solid transitional cell carcinomatous areas and multifocal intraepithelial carcinoma in adjacent atrophic endometrium. The tumor exhibited diffuse infiltrative growth with frequent lymphatic tumor emboli in the myometrium. Immunohistochemical staining for p53 and c-erbB-2 were positive in about 70% of the tumor cells. Carcinoembryonic antigen (CEA) was focally positive. Ki-67 positive cells were present in about 60% of the tumor cells. The tumor directly extended to the cervix and perirectal soft tissue and metastasized to the omentum. Intraoperative pelvic washing cytology was positive for papillary adenocarinoma cells. The possible etiologic role of radiation is discussed, and the literature on endometrial carcinomas developing after RT is reviewed.

    Objective: To study the mechanism, clinical characteristics, therapy regimens, and survival of cervical carcinoma metastases to the brain. Methods: We retrospectively analyzed 11 patients with brain metastases from cervical carcinoma. Results: Two cases were at stage lb, two at IIa, and seven at IIIb, respectively. Histologically, they were squamous cell carcinoma (6 cases), adeno-squamous carcinoma (2 cases), small cell carcinoma (2 cases), or adenocarcinoma (1 cases), poorly differentiated. Eight were accompanied with lung, liver, and bone metastases disease and three had no any other systemic metastases at the time of the brain metastases diagnosis. Two had controlled, and other nine were uncontrolled or progressive primary disease. The median interval from the diagnosis of the primary carcinoma to the detection of brain lesion was 14.6 months. Headache was the most common symptom of brain metastases. Eight of 11 patients developed multiple lesions and other 3 cases had a solitary lesion in brain. The patients were treated by combination of surgery and whole brain radiation therapy (WBRT) (3 cases), stereotactic radiosurgery (SRS) (3 cases), or WBRT (5 cases). The patients had a median survival of 6.6 months. Conclusion: Brain metastases are not always a late complication of cervical carcinoma. The development of the metastases is related to pathological type, poorly differentiation, and advanced stage. Surgery and SRS arc the appropriate therapy regimen for these patients.

In our study, significant amount (30.0% of disease control for a substantial period (1.5 years was observed. The overall surviva l rate in patients of Stage IV carcinoma cervix on various forms of palliative treatment was 18.0%. CONCLUSION: Palliation is achieved by surgery, radiation or chemotherapy, though at tim es, simple palliation is the only feasible option. The poor survival rate was probably due to impr oper reporting & lack of regular follow up in the given socio-economic background. As cure c annot be achieved in advanced carcinoma cervix, palliation is important in alleviating the di stressing symptoms and improving the quality of life

    Onsrud, M.; Grahm, I.; Gaudernack, G.

    Sixteen patients with early stage carcinoma of the uterine cervix treated with primary radical hysterectomy and pelvic lymphadenectomy were compared with 17 patients who four to six weeks before the operation received intracavitary treatment with radium. The calculated radiation dose to the pelvic wall was approximately 10 Gy. The distribution of lymphoid cells in blood and pelvic lymph nodes was studied by an indirect immunoflourescence technique using monoclonal antibodies. The radium treated group showed a significant reduction of circulating OKT4+ (T helper) and OKT8+ (T suppressor/cytotoxic) lymphocytes. The number of Leu7+ (natural killer) cells and 1D5+ cells (monocytes) was not changed, but the ratio between monocytes and T cells was increased after radium therapy. In cell suspensions obtained from the pelvic lymph nodes, the radium treatment induced a significant reduction of the OKT4+ cell fraction. It is concluded that this low dose rate regimen of intracavitary treatment induces changes in the immune system which are of the same type as those seen after external field irradiation.

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

The prognostic impact of LNR with respect to cause-specific survival (CSS and overall survival (OS was analyzed.Results: A total of 118 patients with SCCC were identified. The median follow-up was 30.5 months. All these patients were treated with cancer-directed surgery and lymphadenectomy. Sixty (50.8% patients had nodal metastases. The median LNR was 0.16 in patients with positive lymph nodes. Univariate analysis showed that prognostic factors such as International Federation of Gynecology and Obstetrics (FIGO stage, nodal status, LNR, and local treatment modalities affected CSS and OS (P<0.05. Multivariate analysis showed that LNR was an independent prognostic factor for CSS and OS. Patients with a higher LNR had worse CSS (hazard ratio [HR]: 8.832; 95% confidence interval [CI]: 3.762–20.738; P<0.001 and OS (HR: 8.462; 95% CI: 3.613–19.821; P<0.001.

    Full Text Available Abstract Background The occurrence of skeletal muscle metastases is a very rare event. Only two cases of late skeletal muscle recurrence from cervical cancer have been documented until now. Case presentation A 38-year old patient, submitted to radical hysterectomy and pelvic lymphadenectomy for a squamous FIGO stage IB1 cervical carcinoma, presented after 76 months with a palpable, and painless swelling on the left hemithorax. MRI showed a nodule located in the context of the intercostal muscles. Pathology revealed the presence of metastasis of squamous cell carcinoma of similar morphology as the primary. On the basis of FDG-PET findings, which excluded other sites of disease, surgical excision of the lesion was performed. The patient was triaged to chemotherapy plus external radiotherapy. Conclusion A case of skeletal muscle recurrence from cervical cancer after a very long interval from primary diagnosis is reported. Muscular pain or weakness, or just a palpable mass in a patient with a history of cancer has always to raise the suspicion of muscle metastasis.

    Full Text Available Background: This observational study was aimed to determine the frequency of existence of sero-positivity for human immunodeficiency virus (HIV infection among women of age between 25 to 75 years with invasive cervical carcinoma and to decide whether HIV testing should be included as part of the initial routine work-up of cervical cancer patients. Methods: Histologically proven 120 cases of invasive carcinoma cervix, who came for treatment between 2009-2013, in the department of radiotherapy, after counselling gave consent were investigated for HIV by immunochromatography based rapid test. Results: Out of 120 patients investigated, reports revealed that only two patients (1.67% were HIV seropositive. Both of these patients were already HIV seropositive and on gynaecological screening were found to have malignancy of cervix. No patient of diagnosed carcinoma cervix was found seropositive for HIV. Most patients (106/120 were above 40 years of age, from rural background (92/120 and housewives (80/120. Only 15% (18/120 were smokers. 95.8% (115/120 were of stage II and III. None presented with metastasis. Most common pathology was moderately differentiated carcinoma, in 76 patients (63.3%. Conclusion: Screening for HIV, as part of the initial work up for cervical cancer is not necessary in countries with limited resources and low HIV prevalence.

    Full Text Available Radiotherapy is the primary form of treatment in patients with locally advanced cervical carcinoma. However for residual disease in the form of the persistent lymph nodes, surgery or chemotherapy is recommended. As surgery is not acceptable by every patient and chemotherapy has associated side effects, we hereby report the positive outcome of in vitro expanded natural killer cell and activated T lymphocyte based autologous immune enhancement therapy (AIET for the residual lymphadenopathy in a patient with locally advanced cervical cancer after radiation. After six transfusions of AIET, there was complete resolution of residual lymph nodes and there was no evidence of local lesion. The patient also reported improvement in quality of life. As AIET has been reported as the least toxic among the available therapies for cancer, combining AIET with conventional forms of therapy in similar patients might not only improve the outcome but may also help the patients achieve a good quality of life.

    Long Huang

    Full Text Available BACKGROUND: Small cell carcinoma of the cervix (SCCC is very rare, and due to the long time period required to recruit sufficient numbers of patients, there is a paucity of information regarding the prognostic factors associated with survival. MicroRNAs (miRNAs have been used as cancer-related biomarkers in a variety of tumor types, and the objective of this study was to determine whether microRNA expression profiles can predict clinical outcome in SCCC. METHODOLOGY/PRINCIPAL FINDINGS: Forty-four patients with SCCC who underwent radical hysterectomy between January 2000 and October 2009 were enrolled. Using the GeneCopoeia All-in-One™ Customized Human qPCR Primer Array, the expression profiles of 30 miRNAs associated with tumor metastasis was obtained from the formalin-fixed paraffin embedded samples of all 44 patients. Seven miRNAs, has-let-7c, has-miR-10b, has-miR-100, has-miR-125b, has-miR-143, has-miR-145 and has-miR-199a-5p were significantly down-regulated in advanced stage SCCC patients (FIGO IB2-IV compared to early stage SCCC patients (FIGOIB1. Among, downregulation of six miRNAs, has-let-7c, has-miR-100, has-miR-125b, has-miR-143, has-miR-145 and has-miR-199a-5p were significantly associated with lymph node metastasis and reduced survival in SCCC. Kaplan-Meier survival analyses revealed that SCCC patients with low expression of has-miR-100 (P = 0.019 and has-miR-125b (P = 0.020 projected a significant tendency towards poorer prognosis. CONCLUSIONS/SIGNIFICANCE: This study demonstrates that downregulation of 7 miRNA associated with advanced stage, 6 miRNAs with metastasis and 2 with poor prognosis in SCCC. Functional analysis of these miRNAs may enhance our understanding of SCCC, as altered expression of specific miRNAs may regulate the metastatic pathway and provide novel targets for therapy.

    Full Text Available Isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. We describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases tothe bony calvarium as the sole site of metastasis. The patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, FIGO stage IIIb, whose initial treatement was chemoradiation therapy. After 22 sessions of external-beam radiation,she developed headaches. On physical examination she had skull bone tenderness. On plain skull X-ray, there were osteolytic bony lesions. Brain MRI showed multiple enhancing skull bone metatstses. Eventually, a whole body bone scintigraphy revealed isolated diffuse increased activity in the bony calvarium. In the literature review, wefound only three similar cases of cervical cancer with scalp metastases and involvement of the bony calvarium.

    Full Text Available OBJECTIVE: To compare survival and toxicity of three different treatments for stage IIIB cervix cancer: low-dose-rate (LDR, high-dose-rate (HDR brachytherapy and association of HDR and chemotherapy. METHODS. Between 1985 and 2005, 230 patients with FIGO stage IIIB squamous cell carcinoma of the uterine cervix received 4-field pelvic teletherapy at doses between 40 and 50.4 Gy, with a different complementation in each group. The LDRB group, with 42 patients, received one or two insertions of LDR, with Cesium-137, in a total dose of 80 to 100Gy at point A. The HDR group, 155 patients received HDR in 4 weekly 7 Gy fractions and 9 Gy to 14.4 Gy applied to the involved parametria. The CHT group, 33 patients, were given the same treatment as the HDR group and received 5 or 6 weekly cycles of cisplatin, 40 mg per m2. RESULTS: The five-year progression-free survival (PFS was 60% for the HDR group and 45% for the LDR group, and the two-year PFS for the CHT group was 65% (p = 0.02. The five-year Overall Survival (OS was 65% for the HDR group and 49% for the LDR group. The two-year OS was 86% for the CHT group (p = 0.02. Rectum toxicity grade II was 7% for the LDR group, 4% for the HDR group and 7% for the CHT group that had one case of rectum toxicity grade IV. CONCLUSION: Patients that received HDR had better OS and PFS. The Chemotherapy-HDR association showed no benefit when compared to HDR only. Toxicity rates showed no difference between the three groups.OBJETIVO: Comparar três diferentes tratamentos para câncer de colo do útero, estádio IIIB: braquiterapia de baixa taxa de dose (LDR, alta taxa de dose (HDR e associação entre HDR e quimioterapia, quanto à sobrevida e toxicidade.

    Seventy patients having squamous-cell carcinoma of the uterine cervix FIGO (Federation Internationale de Gynecologie et d'Obstetrique : International Federation of Gynecology and Obstetrics) Stage I-II with negative lymph nodes and positive parametrial involvement received postoperative radiotherapy following radical hysterectomy and pelvic lymphadenectomy. In 48 patients with microscopic parametrial involvement had a 5-year survival rate of 75%. The overall recurrence was 13% (9 of 70). The sites of failure were 3 pelvic alone, 5 distant metastases alone, and 1 combined pelvis and para-aortic lymph node. All of those with recurrence were Stage-II cases. The absolute pelvic-control rate was 94.3% (66/70). Fifty-six percent of the patients experienced mild-to-moderate lymphedema. Severe complications requiring surgical intervention were observed in 6 patients (5 bowel obstructions and 1 femoral head fracture). A review of the literature suggests that early carcinoma can be successfully treated by surgery alone. Taking into consideration the risk and benefits involved, postoperative radiotherapy is not recommended for most patients with cervical carcinoma with negative lymph nodes and positive parametrial involvement in the present form, despite excellent local control. However, no definite conclusion can be drawn from this retrospective analysis. (author).

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

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

    Full Text Available Postmenopausal bleeding (PMB is a discharge that occurs following the firm diagnosis of menopause, which is at least six months from the end of women’s menstrual cycle but not to be confused with infrequent or irregular periods occurring around the time of menopause. It is a common problem representing 5% of all gynecology outpatient attendances which are to eliminate endometrial cancer as the cause of bleed and PMB should be reported urgently to the gynecologist. Uterine bleeding in postmenopausal women is highly indicative clinically of malignancy originating from cervix or endometrium and Human papilloma virus (HPV is one of the causative agent for carcinoma cervix. Incidence of carcinoma cervix increases with the age in mature women, however, incidence of human papillomavirus (HPV infection reduces as menopause sets in. The presence of the virus could be used as an early indication of disease potential. Because the Pap test can only detect clinical evidence of cervical disease, molecular-based diagnostic tools are being used more frequently to detect the virus before abnormal cell growth can be observed. This study was aimed to determine the status of cervical cancer and HPV 16 DNA positivity in relation to postmenopausal bleeding.

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

  18. Role of surgery in breast metastasis from carcinoma of the cervix

    Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

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

    Since its recognition about 150 years ago, there has been much progress in the understanding of the pathogenesis, prevention, early detection and management of carcinoma of the uterine cervix. Important historical landmarks include the (1) recognition of pre-invasive and pre-clinical lesions, and the devise of various systems for reporting these lesions, (2) improvements in diagnostic techniques particularly colposcopy, (3) advent of therapeutic procedures (electrocoagulation, cryotherapy, laser therapy and loop electrosurgical excision), and (4) recognition of the aetiological relationship between the human papillomavirus and cervical neoplasia. The susceptibility of the cervical transformation zone to malignant change is now well recognised. The WHO classification system remains the one most commonly utilised for histological reporting of cervical cancers. In the recent 1994 update, cervical carcinoma is divided into 3 main categories: squamous cell carcinoma, adenocarcinoma and other epithelial tumours. Squamous cell carcinoma (60-80%) predominates among invasive cervical carcinoma. Recognised variants include verrucous, warty (condylomatous), papillary squamous (transitional) and lymphoepithelioma-like carcinoma. Adenocarcinoma (5-15% of invasive carcinomas) shows an increasing trend in young females. Like its squamous counterpart, preinvasive and microinvasive versions are known. Variants such as mucinous, endometrioid, clear cell, mesonephric, serous, villoglandular and minimal deviation carcinoma are now defined. Adenosquamous carcinoma (5-25%), adenoid-cystic, adenoid-basal, neuroendocrine and undifferentiated carcinomas constitute other epithelial tumours of the cervix. The management of invasive cervical carcinoma remains heavily dependent on its stage. The FIGO staging system remains the most widely used. The 1995 update provides more definite criteria in subdividing stage IA tumours by delimiting stromal invasion of stage IA1 lesions to a maximum depth

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objetive is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomopathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%. For the dynamic GE sequence with intravenous gadolinium the sensitivity was 86.6%, the specifity 86.6%, the posistive predictive value 86.6%, the negative predictive value 86.6% and the reliability 86.6%.

    Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.%目的:探讨XRCC1基因Arg194Trp、Arg399Gln单核苷酸多态性(SNP)与外生型宫颈鳞状细胞癌放疗敏感性的关系。方法选择经组织病理学确诊的外生型宫颈鳞状细胞癌患者73例。其中临床分期Ⅰ期4例,Ⅱ期36例,Ⅲ期30例,Ⅳ期3例。肿瘤直径≤4 cm 30例,肿瘤直径>4 cm 43例;A点剂量≤80 Gy

    This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study, The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, Iymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer following simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was 45 - 50 Gy. Vagina cuff irradiation was performed, after completion of the external beam irradiation, al a low-dose rate of CS-137, with the total dose of 4488-4932 chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months (15-108 months), The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were 98%, 95% and 94%, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients (9%) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Our results indicate that postoperative radiation therapy can

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

    tumor that contains a mixture of malignant cells with squamous and glandular differentiation. The literature points to the importance of making this diagnosis when the cellular components are still well differentiated in the sample, otherwise the tumor may be erroneously interpreted as squamous carcinoma or adenocarcinoma. This study describes an unusual presentation of a adenosquamous carcinoma in a 47 year old patient. After conflicting cytological diagnoses and a history of abnormal uterine bleeding caused by cervical endometriosis, the patient was subjected to radical hysterectomy and a final diagnosis was obtained. The tumor was diagnosed as adenosquamous carcinoma. In many aspects, however, it was similar to the adenoid basal carcinoma. Characteristic features of the adenoid basal carcinoma such as the presence of high-grade squamous intraepithelial lesion in the surface epithelium, squamous and glandular differentiation in the center of the neoplastic mass, and basaloid cells in deep areas of the tumor were observed. Therefore, the following elements usually absent from adenoid basal carcinoma were present in this case: atypia and mitotic figures in undifferentiated cells, squamous-mucinous intraepithelial lesion (SMILE in the superficial areas. Epidemiological and clinical data, such as patient age (47, race (white and presentation (a cervical mass, concurred to exclude the diagnosis of adenoid basal carcinoma. Other differential diagnoses include pure squamous carcinoma or adenocarcinoma, collision tumor, and endometrial adenocarcinoma with squamous differentiation invading the uterine cervix.

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

    From August 1978 through December 1980, 119 patients of previously untreated carcinoma of the uterine cervix were treated using RALS, remote afterloading high dose rate intracavitary therapy at our department. The data from 92 out of 119 patients were available for analysis of rectal complication. The incidence of major rectal complications was only 2% (2/92). Uni- and multivariate analyses were used based on the external criterion variable of rectal complication which included even minor injuries. By using these methods, it was clearly indicated that these factors such as TDF of rectum, Z-coordinate of weighted geometric center (WGC-Z), the dose of whole pelvic irradiation, history of chemotherapy and Treponema pallidum hemoagglutination test (TPHA) were important for occurrence of rectal complication. According to discriminant score, 71 out of 92 cases (77%) could be correctly discriminated.

    AT-rich interactive domain 1A (ARID1A) is a tumor suppressor gene involved in chromatin remodeling which encodes ARID1A (BAF250a) protein. Recent studies have shown the loss of ARID1A expression in several types of tumors. This retrospective study was designed to evaluate the differences in tissue expressions of ARID1A in a spectrum of cervical neoplasms. Cervical intraepithelial neoplasms, invasive squamous or adenosquamous carcinomas were identified in 100 patients recently diagnosed as cervical neoplasms based on pathology databases. In this series, there were 29 low- and 29 high-grade cervical intraepithelial neoplasms, 27 squamous cell carcinomas, and 15 adenosquamous carcinomas. Mean age of the patients was 47.8 ± 13 years (20-80 years). It was determined that the expression of ARID1A was statistically significantly down-regulated in adenosquamous carcinomas when compared with non-invasive or invasive squamous cell carcinomas (p = 0.015). Lower levels of the ARID1A expression were detected in cases with adenosquamous carcinomas (60%), low- or high-grade squamous intraepithelial lesion (SIL) (31%), and squamous cell carcinomas (18.5%). Our findings have demonstrated the presence of a correlation between ARID1A expression and adenomatous differentiation of uterine squamous cell carcinomas. Therefore, ARID1A gene may suggestively have a role in the pathogenesis of cervical adenosquamous carcinomas.

    Full Text Available Background: Cervical cancer remains the most common cancer among women in this part of the world. Bangladesh has the highest level of incidence and mortality rates due to cervical cancer among women. Cervical cancer is a preventable disease by screening and treatment of pre-invasive condition. Unfortunately, there is no effective screening program in Bangladesh.Objective: The objective was to analyze the clinico-pathologic characteristics and, subsequently the therapy delivered to the patients.Materials and method: This cross sectional study was done from January to December 2011 in oncology division of Delta Medical College and Hospital, Dhaka, Bangladesh. During this period a total of 2264 female carcinoma patients were registered. Out of them 523 patients were with the diagnosis of carcinoma of cervix. Evaluation and characterization of patients with carcinoma cervix were done according to the age group, clinical stages and surgical status. External beam radiotherapy (EBRT and doses, brachytherapy doses and fractions, time interval between EBRT and brachytherapy, neo-adjuvant and concurrent chemotherapy status were the factors taken into consideration for the analysis of treatment of these patients.Results: The study revealed that the incidence of carcinoma cervix was 23% and highest incidence was between 40-50 years of age group, most of the patients were in Stage IIB (34% and IIIB (28% and 31% with unknown stage. About 44% patients were referred postoperatively and most of them with unknown stage. Almost 90% patients received EBRT, 24% patients received concurrent chemo-radiation, 46% of them completed 5 cycles of concurrent chemotherapy and 8.6% patients received neo-adjuvant chemotherapy. About 69% patients received brachytherapy with HDR Co-60 sources and 23% of patients received their brachytherapy treatment after 12 weeks of completion of EBRT.Conclusion: Lack of proper clinical evaluation and documentation, delay in referral and lack

    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.

    Full Text Available External beam radiotherapy (EBRT for carcinoma of uterine cervix is a basic line of treatment with three dimensional conformal radiotherapy (3DCRT in large number of patients. There is need for an established method for verification dosimetry. We tried to document absorbed doses in a group of carcinoma cervix patients by inserting a 0.6 cc Farmer type ion chamber in the vaginal cavity. A special long perspex sleeve cap is designed to cover the chamber for using in the patient′s body. Response of ionization chamber is checked earlier in water phantom with and without cap. Treatment planning was carried out with X-ray computed tomography (CT scan and with the chamber along with cap in inserted position, and with the images Xio treatment planning system. Three measurements on 3 days at 5-6 fraction intervals were recorded in 12 patients. Electrometer measured charges are converted to absorbed dose at the chamber center, in vivo. Our results show good agreement with planned dose within 3% against prescribed dose. This study, is a refinement over our previous studies with transmission dosimetry and chemicals in ampules. This preliminary work shows promise that this can be followed as a routine dose check with special relevance to new protocols in the treatment of carcinoma cervix with EBRT.

    Full Text Available Background and Purpose: Conventional portals, based on bony anatomy, for external beam radiotherapy for cervical cancer have been repeatedly demonstrated as inadequate. Conversely, with image-based conformal radiotherapy, better target coverage may be offset by the greater toxicities and poorer compliance associated with treating larger volumes. This study was meant to dosimetrically compare conformal and conventional radiotherapy. Materials and Methods: Five patients of carcinoma cervix underwent planning CT scan with IV contrast and targets, and organs at risk (OAR were contoured. Two sets of plans-conventional and conformal were generated for each patient. Field sizes were recorded, and dose volume histograms of both sets of plans were generated and compared on the basis of target coverage and OAR sparing. Results: Target coverage was significantly improved with conformal plans though field sizes required were significantly larger. On the other hand, dose homogeneity was not significantly improved. Doses to the OARs (rectum, urinary bladder, and small bowel were not significantly different across the 2 arms. Conclusion: Three-dimensional conformal radiotherapy gives significantly better target coverage, which may translate into better local control and survival. On the other hand, it also requires significantly larger field sizes though doses to the OARs are not significantly increased.

    Ninety-two consecutive patients with stages IB and IIA carcinoma of the cervix were treated by one of two regimens: pre-operative intracavitary caesium-137 followed by a Wertheim hysterectomy (group 1) or staging laparotomy with biopsy of suspicious lymph nodes (group 2) (if there was no evidence of tumour on examination of a frozen section of the lymph nodes a Wertheim hysterectomy was performed, but if a tumour was present the abdomen was closed and a course of radical irradiation given). When there was evidence of extracervical spread on examination of the specimen after the Wertheim hysterectomy, postoperative irradiation was given. It was found that clinical staging had been incorrect in 38.5% of patients thought to have stage IB disease and in 71.4% of those thought to have stage IIA disease. The actuarial survival curves showed no significant statistical difference between group 1 and group 2. When examination of the operative specimen showed tumour invasion of the parametrium only, the disease was well controlled by postoperative irradiation (all 7 such patients survived). On the other hand, when there was evidence of tumour invasion of pelvic lymph nodes the 4-year survival rate fell to 31% (4 out of 13 patients), despite the use of postoperative irradiation.

    Full Text Available Aim: To report the outcome of carcinoma cervix patients treated radically by external beam radiotherapy and high dose rate intracavitary radiotherapy. Material and Methods: From January 2005 to December 2006, a total of 709 newly diagnosed cases of carcinoma cervix were reported in our department. All cases were staged according to the International Federation of Gynecologist and Oncologist staging system. Out of 709 cases, 342 completed radical radiotherapy and were retrospectively analyzed for the presence of local residual disease, local recurrence, distant metastases, radiation reaction, and disease free survival. Results: There were 11(3.22%, 82(23.98%, 232(67.83%, and 17(4.97% patients in stages I, II, III, and IV, respectively. The median follow up time for all patients was 36 months (range 3 -54 months. The overall treatment time (OTT ranged from 52 to 69 days (median 58 days. The 3 year disease free survival rate was 81.8%, 70.7%, 40.08%, and 11.76% for stages I, II, III, and IV, respectively. There were 91 (26.6% cases with local residual diseases, 27(7.9% developed distant metastasis, and 18(5.26% pts had local recurrence. Discussion: The results of this study suggest that radical radiotherapy with HDR brachytherapy was appropriate for the treatment of early staged cancer of uterine cervix. For locally advanced cancer of cervix addition of concurrent chemotherapy, higher radiation doses, reduction of overall treatment time to less than 8 weeks, and use of latest radiotherapy techniques such as IMRT is recommended to improve the results.

    Full Text Available Metastatic cancers of the pancreas are rare, accounting for approximately 2-4% of all pancreatic malignancies. Renal cell carcinoma is the most common solid tumor that metastasizes to the pancreas. Here, we present a case of uterine cervical carcinoma metastasizing to the pancreas and review the literature regarding this rare event. A 44-year-old woman with a uterine cervical tumor had undergone radical hysterectomy and had been diagnosed pathologically with stage Ib mixed adenoneuroendocrine carcinoma in 2004. She underwent concurrent radiotherapy and chemotherapy postoperatively. Pulmonary metastases subsequently appeared in 2008 and 2011, and she underwent complete resection of the lung tumors by video-assisted thoracic surgery. Although she was followed up without any treatment and with no other recurrences, positron emission tomography revealed an area of abnormal uptake within the pancreatic body in 2012. Enhanced computed tomography demonstrated a 20-mm lesion in the pancreatic body and upstream pancreatic duct dilatation. Endoscopic ultrasonography-guided fine needle aspiration was performed and pathological examination suggested neuroendocrine carcinoma (NEC. On the basis of these results and the patient's oncological background, lesions in the pancreatic body were diagnosed as secondary metastasis from the cervical carcinoma that had been treated 8 years earlier. No other distant metastases were visualized, and the patient subsequently underwent middle pancreatectomy. Pathological examination showed NEC consistent with pancreatic metastasis from the uterine cervical carcinoma. The patient has survived 7 months since the middle pancreatectomy without any signs of local recurrence or other metastatic lesions.

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of topotecan in combination with cisplatin for the treatment of recurrent and stage IVB carcinoma of the cervix, in accordance with the licensed indication, based upon the evidence submission from the manufacturer to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The outcomes measured were overall survival, progression-free survival, response rates, adverse effects of treatment, health-related quality of life (HRQoL) and quality-adjusted life-years (QALYs) gained. The manufacturer stated that topotecan plus cisplatin is the only combination regimen to date to have demonstrated a statistically significant survival advantage compared to cisplatin monotherapy in the licensed population. The clinical evidence came from three clinical trials comparing topotecan plus cisplatin with cisplatin monotherapy (GOG-0179), topotecan plus cisplatin with paclitaxel plus cisplatin (GOG-0169), and four cisplatin-based combination therapies: topotecan plus cisplatin, paclitaxel plus cisplatin, gemcitabine plus cisplatin, and vinorelbine plus cisplatin (GOG-0204). Results from GOG-0179 showed greater median overall survival with topotecan plus cisplatin than with cisplatin monotherapy: 9.4 months versus 6.5 months. Similar results were also reported for median progression-free survival. Response rates also showed an advantage with topotecan plus cisplatin compared with cisplatin monotherapy. The response rates in patients receiving cisplatin monotherapy were very low, but the potential reasons for this were not discussed in the manufacturer's submission. Patients receiving topotecan plus cisplatin experienced a greater number of adverse events and the ERG was concerned with some of the assumptions related to HRQoL. In the base-case direct comparison, the incremental cost

    Full Text Available To establish the role of co-overexpression of bcl-2 and c-myc protooncogenes in uterine cervix carcinogenesis, we examined 138 tissue samples of low grade cervical squamous intraepithelial lesions (SIL, high grade SIL, portio vaginalis uteri (PVU carcinoma in situ and PVU carcinoma invasive, stage IA-IIA (study group and 36 samples without SIL or malignancy (control group. The expression of bcl-2 and c-myc was detected immunohistochemically using a monoclonal antibody. Fisher’s exact test (P<0.05 was used to assess statistical significance. Overexpression of bcl-2 was found to increase in direct relation to the grade of the cervical lesions. High sensitivity was of great diagnostic significance for the detection of these types of changes in the uterine cervix. On the basis of high predictive values it can be said that in patients with bcl-2 overexpression there is a great possibility that they have premalignant or malignant changes in the uterine cervix. Co-overexpression of bcl-2 and c-myc oncogenes was found only in patients with PVU invasive carcinoma (6/26-23.0%. Statistically significant difference was not found in the frequency of co-overexpression in patients with PVU invasive carcinoma in relation to the control group (Fisher’s test; P=0.064. The method's sensitivity of determining these oncogenes with the aim of detecting PVU invasive carcinoma was 23%, while specificity was 72.2%. On the basis of high predictive values (100%, speaking in statistical terms, it can be concluded that all patients with co-overexpression of bcl-2 and c-myc oncogenes will have PVU invasive carcinoma. We confirmed in our research that co-overexpression of bcl-2 and c-myc oncogenes was increased only in PVU invasive carcinoma. However, a more extensive series of samples and additional tests are required to establish the prognostic significance of bcl-2 and c-myc co-overexpression in cervical carcinogenesis.

    Full Text Available Bone metastasis from carcinoma cervix is uncommon, especially in the distal appendicular skeleton. A 36 year old lady presented with carcinoma of uterine cervix, FIGO, stage IIb. She was treated with radical radiotherapy. Nine months later, she developed an isolated lytic lesion in right fibula, which turned out to be a metastatic lesion. The patient is doing well, 3 years after the surgical excision of metastasis. This is one of the few documented cases of metastasis to fibula, arising from carcinoma of uterine cervix and probably the first with isolated metastasis of this site. Unlike the dismal outcome commonly seen in patients with bone secondaries, she continues to be disease free and alive at 39 months of follow up, after the development of skeletal metastasis.

    We present a case of spontaneous rupture of bladder diverticulum three years after postoperative whole pelvic irradiation (50.4 Gy) for carcinoma of the uterine cervix. The patient had suffered from a neurogenic bladder after hysterectomy, but excretory urography revealed no abnormalities. Bladder diverticulum was found two years later. Spontaneous rupture of the urinary bladder is one of the late complications associated with radiotherapy, although it is very rare. Postoperative neurogenic bladder may also be associated with rupture. We should be aware of this rare complication in patients who receive pelvic irradiation. (author)

    To compare the efficiency of hybridization methods for the detection of HPV genome, 22 cases of invasive squamous cell carcinoma of the uterine cervix were analyzed by Southern blot analysis and in situ hybridization carried out with 35S- and biotin-labeled probes. These cases contained from less than one to as many as 50 copies per cell of HPV 16 and 18 types. To increase the sensitivity of biotinylated probes, a silver enhancement procedure of the peroxidase reaction product was applied. Results showed that in situ hybridization performed with isotopic probes is as sensitive as Southern blot analysis and is more sensitive than that performed with biotin-labeled probe. However, the application of the silver enhancement procedure increases the percentage of HPV-positive cases from 27 to 50%.

    A forty-year-old woman with a known case of carcinoma cervix underwent 18-fluorodeoxyglucose positron emission tomography.computed tomography (18-FDG PET/CT) for evaluation of abdominal lymphadenopathy. Her treatment history included radical hysterectomy and radiotherapy 6 months ago. She complained of weight loss of 7 kg over last 5 months. The maximum intensity projection (MIP) image (Fig. 1a, arrows) revealed multiple areas of intense FDG uptake, which on CT and fused PET/CT images were localized to multiple lymph nodes in bilateral cervical region, right axilla, mediastinum and abdomen. The SUVmax of right axillary lymph nodes (most FDG avid of all lymph node groups) was 15.3. There was no evidence of metabolically active disease or CT demonstrable abnormality in rest of the body. Presence of metabolically active disease in extensive supradiaphramatic lymphadenopathy was unusual for a case of carcinoma cervix. This finding, along with history of significant weight loss and absence of extranodal disease, was suspicious for unrelated pathology like lymphoproliferative disorder or granulomatous disease. Mixed malignant and benign lymphadenopathy was also considered a possibility. To solve the conundrum, 18-fluoro-L-thymidine (FLT) PET/CT was performed on the next day. This scan was performed to assess the proliferation rate in various above-mentioned lymph nodes, and to plan the optimum site of biopsy. The FLT PET scan (Fig. 1b) showed physiological distribution of the tracer in bone marrow, liver, gall bladder and urinary bladder. There was minimal FLT uptake in the enlarged, FDG avid lymph nodes (Fig. 1c and d). SUVmax of FLT uptake in right axillary lymph nodes was 1.4 (SUVmax of FDG uptake = 15.8). The SUVmax of FLT uptake in cervical, mediastinal and abdominal lymph nodes were 1.3, 1.4 and 1.0 respectively. (SUVmax of FDG uptake 12.1, 12.7 and 11.9, respectively). Considering avidity for FDG and non-avidity of proliferation marker tracer (FLT), possibility of

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

    Alterations in tannic acid (TA) binding capacity of cell surface carbohydrates in normal, premalignant, and malignant squamous epithelium of the human uterine cervix have been studied using electron microscopic visualization in combination with microdensitometric evaluation. While in normal epithelium there is distinct binding in four to five cell layers of the deep intermediate zone, cells of carcinoma in situ and invasive cancer lesions lack TA binding. In moderate dysplasia an intermediate reacting pattern is found. Deep intermediate cells in areas bordering the carcinoma in situ lesions do not show any binding, although their ultrastructure cannot be distinguished from similar cells in normal tissue. The TA deposition within the deep intermediate zone is probably related to the presence here of glycoprotein-containing membrane-coating granules. The finding that TA binding discriminates between cells in normal squamous epithelium and morphologically normal cells in juxtaposition with lesional areas in premalignant and malignant epithelium opens the possibility for a more reliable cytologic diagnosis of cervical epithelial neoplasia.

    Full Text Available Abstract Purpose To evaluate the pathologic response of cervical carcinoma to external beam radiotherapy (EBRT and high dose rate brachytherapy (HDRB and outcome. Materials and methods Between 1992 and 2001, 67 patients with cervical carcinoma were submitted to preoperative radiotherapy. Sixty-five patients were stage IIb. Preoperative treatment included 45 Gy EBRT and 12 Gy HDRB. Patients were submitted to surgery after a mean time of 82 days. Lymphadenectomy was performed in 81% of patients. Eleven patients with residual cervix residual disease on pathological specimen were submitted to 2 additional insertions of HDRB. Results median follow up was 72 months. Five-year cause specific survival was 75%, overall survival 65%, local control 95%. Complete pelvic pathological response was seen in 40%. Surgery performed later than 80 days was associated with pathological response. Pelvic nodal involvement was found in 12%. Complete pelvic pathological response and negative lymphnodes were associated with better outcome (p = .03 and p = .005. Late grade 3 and 4 urinary and intestinal adverse effects were seen in 12 and 2% of patients. Conclusion Time allowed between RT and surgery correlated with pathological response. Pelvic pathological response was associated with improved outcome. Postoperative additional HDRB did not improve therapeutic results. Treatment was well tolerated.

    Full Text Available Purpose: Role of risk factors in cervical carcinogenesis and strategies for control of the disease have been assessed from the accumulated cytological data, derived from 35 years of hospital-based screening in Lucknow, North India. Materials and Methods: A total of 36,484 women have been cytologically screened during a span of 35 years (April 1971 - June 2005 in the Gynaecology out patient department (OPD of Queen Mary′s Hospital. Results: The frequency of Squamous Intraepithelial Lesion (SIL and carcinoma was found to be 7.2% and 0.6%, respectively, in the present study. The study revealed high age and parity as a predominant factor in cervical carcinogenesis, while viral sexually transmitted disease (STDs -human papilloma virus (HPV and Herpes simplex virus (HSV were also largely associated with SIL cases. The study emphasized great value of clinically downstaging the cervical cancer by detecting cervical cancer in the early stage. The study also revealed a significant difference in the frequency of SIL in symptomatic and asymptomatic women. Conclusion: Based on the analyzed data, it was felt that single lifetime screening, which appears to be the most feasible and affordable mode for control of carcinoma cervix in developing countries like India, should be carried out in all women of high parity irrespective of age (with three or more children and in older women above the age of 40 years irrespective of parity.

    Full Text Available Abstract Background Chromosomal Comparative Genomic Hybridization (CGH has been applied to all stages of cervical carcinoma progression, defining a specific pattern of chromosomal imbalances in this tumor. However, given its limited spatial resolution, chromosomal CGH has offered only general information regarding the possible genetic targets of DNA copy number changes. Methods In order to further define specific DNA copy number changes in cervical cancer, we analyzed 20 cervical samples (3 pre-malignant lesions, 10 invasive tumors, and 7 cell lines, using the GenoSensor microarray CGH system to define particular genetic targets that suffer copy number changes. Results The most common DNA gains detected by array CGH in the invasive samples were located at the RBP1-RBP2 (3q21-q22 genes, the sub-telomeric clone C84C11/T3 (5ptel, D5S23 (5p15.2 and the DAB2 gene (5p13 in 58.8% of the samples.

    Full Text Available Primary small cell carcinoma of the vagina is quite rare, and a standard treatment has not been established yet. Herein, we report a case of an 81-year-old woman who was diagnosed with a vaginal tumor without continuity with the uterine cervix. Histopathological diagnosis indicated alveolar solid growth of nuclear chromatin-rich atypical cells with a high N/C ratio and a partially recognized rosette-like structure, suggesting a differentiated neuroendocrine system. Chromogranin A and synapto- physin were positive. Stage I vaginal small cell carcinoma localized to the vagina was diagnosed. The tumor disappeared by radiation monotherapy with external beam irradiation and endocavitary irradiation. The patient remains alive without any disease 1 year and 8 months after the treatment, suggesting the efficacy of radiotherapy in small cell carcinoma of the vagina.

    While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

    In blood, the accumulation of terminally differentiated (TD) T cells during HIV infection is associated with CD4 T cell loss and HIV disease progression. Here, we investigated the maintenance and functional characteristics of memory T cells at the cervix. We found that CD4 T cell depletion at the cervix mirrors CD4 depletion in blood. In all women, depletion of CD4 T cells at the cervix was associated with significant reductions in CD45RA- CCR7+ (central memory [CM]) T cells and the accumulation of CD45RA+ CCR7- (TD T cells). We determined whether inflammation in the genital tract was associated with the local differentiation of T cells at the cervix. In uninfected women, genital tract inflammation was associated with the accumulation of CD45RA- CCR7+ CM CD4 T cells and reduced frequencies of CD45RA+ CCR7- TD cells at the cervix. This finding may reflect the fact that, in the absence of HIV infection, TD T cells may be slowly lost in the presence of genital inflammation, while CD45RA- CCR7+ CM T cells are recruited to replenish the diminishing CD4 T cell pool. Following global stimulation with phorbol myristate acetate (PMA)-ionomycin, we noted a significant interleukin 2 (IL-2) deficit in both cervical and blood CD4 T cells from HIV-infected women compared to uninfected women, while gamma interferon (IFN-γ) production was similar, irrespective of HIV status. Few HIV-infected women had detectable IFN-γ and IL-2 HIV-specific T cell responses at the cervix, and these responses were significantly lower in magnitude than the corresponding responses in blood. These data suggest that CD4 depletion was associated with the accumulation of terminally differentiated T cell phenotypes at the cervical mucosa defective in their ability to produce IL-2. CD4 depletion and compromised immunity at the cervix may be accompanied by progressive decline of central memory-like T cells and development of T cells toward terminally differentiated phenotypes.

    Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature. The authors present a case of a man with a diagnosis of subungual squamous cell carcinoma in the hallux, without bone involvement, which was submitted to the appropriate surgical treatment.

    331 patients of stage IIb uterine cervix cancer treated by radiation alone at Kosin Medical Center between June 1980 and Dec. 1985 were analysed to determine parameters of radiotherapy associated to disease states. Survival rate was highest among the reported (82.8% for crude and 82.4% for disease free survival). Pelvic control rate in 6 weeks after the end of radiotherapy was 93.6% in the patients treated with ICR following total pelvic radiation and 71.6% with small field additional external irradiation. 5 year survival rate in those who achieved pelvic control was 98. 9% and 12.9% in those who had pelvic failure and/or metastasis after radiation. The survival rate figured maximal 88.5% with dosage of 7500-8500 cGy to point A with acceptable incidence of complications (4.9%) but without increasing survival above it and minimal 74.1% with dosage of less than 6500 cGy. The treatment failure was counted 18.7% (62 of 331 patients): Local failure 72. 6% ( 45 of 62 patients), locoregional failure 3.2% (2 of 62 patients) and distant failure 24% (15 of 62 patients). Late complications were found In 50 patients (15.1%) and 42% of them was rectal bleeding and stenosis. The dose of 8500 cGy to point A was found to be critical for complication and 70% of complications occurred above it and was more serious one such as fistula. Rectal complications were developed above rectal dose 6500 cGy and bladder complication above bladder dose 7500 cGy. Major cause of death was cachexia due to locoregional failure (73.7% of death), next was due to metastasis to lung, liver and bone, and only 3 patients died of complication of intestinal perforations and obstruction. In conclusion higher external radiation dose for a bulky uterine cervix and barrel shaped uterus was essential for local control.

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

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

    2013-01-01

    Full Text Available Background: Standard treatment of advanced cervical cancer is concurrent chemoradiation. Radical radiotherapy for carcinoma cervix includes pelvic external beam radiotherapy (EBRT with the concomitant platinum based chemotherapy followed by intracavitary brachytherapy (ICBT to boost central disease. Management of patients who are suboptimally treated, especially, after unsuccessful ICBT insertion is not well-defined. This study explores the role of hysterectomy in these patients. Materials and Methods: From January 2006 to December 2011, 38 patients with locally advanced cervical cancer, in whom ICBT insertion was unsuccessful, were analyzed retrospectively. Operable patients with no parametrial involvement underwent hysterectomy and outcomes (recurrence free and overall survival were noted. Results: The major complications in post operative period were wound infection, paralytic ileus and bladder atony all of which were conservatively managed with no mortality. At median follow-up of 36 months (range 12-60 months there was no recurrence in patients with stage 1B2 and stage IIA, 25 out of 38 (65.8% were event free and the overall survival was 71%. Conclusion: Many patients in Indian scenario receive suboptimal therapy in locally advanced cervical cancer. EBRT with chemotherapy followed by type 1 extra-fascial hysterectomy can be a good alternative for these patients.

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

    Since April 1983 patients with gynecologic tumors have been irradiated with the HDR afterloading method at the University Hospital of Cologne. The therapy scheme for the carcinoma of the cervix consists of a combination of intracavitary contact irradiation and external radiotherapy. Brachytherapy is preponderant in an early stage of tumor extension, whereas teletherapy contributes more to the total dose in advanced stages. At first, the pelvis is totally exposed to a homogenous irradiation, so the shrunken tumor can more easily be arrived by curietherapy. The therapy scheme is described for the different tumor stages with its dosages, fractionations, and treatment pauses. Besides the use of special multiple-way applicators, the risk organs are protected by collimating with a block the middle part of the external irradiation field as soon as the maximum permissible dose is reached. A special block shape minimizes the dose irregularities at the field borders. The total physical dose at point A is about 60 Gy. The high dose rate of HDR afterloading has to be considered when calculating the biologic efficient dose. Here the dose rate factor furnishes a rough relation to the established radium dosage.

    Results of thirty two autopsies in the cases of carcinoma of the cervix experienced in ten years were analyzed. Fourteen cases received surgery and postoperative irradiation. Fourteen cases had external irradiation combined with intracavitary irradiation. Cancer was the cause of death in 81.3% of the whole cases, and it caused cachexia in many cases of the two groups. Uremia and uremic complication were found in 8 cases of the operative group, and in 2 of the radiotherapy group. High incidences of intrapelvic local recurrence and metastasis to other organs were found in the operative group. Cancerous infiltrative involvement of the bladder was often observed, such as in 11 cases of the operated group and in 9 cases of the irradiation group. Cancerous hydronephrosis was found in 10 and 5 cases of the operation and irradiation group, respectively; non-cancerous hydronephrosis was found in 2 of the former and in 4 of the latter. The radiotherapy group had a longer survival period than the other, without severe side effects in the urinary system. This suggested that radiotherapy is of value in treatment of cervical cancer.

    Objective: To report treatment results of 512 cases of carcinoma of uteri and investigate the way to improve treatment effects. Methods: The 5-year survival rate and the factors influencing the prognosis of 512 cases of uteri were analyzed retrospectively. Results: The 5-year survival rate after radiotherapy was as follows: stage Ⅰ: 100%; stage Ⅱ: 74.5%; stage Ⅲ: 56.5%; stage Ⅳ: 28.6%. Overall 5-year survival rate was 65.4%, which was almost the same as traditional intracavitary injection (65.7%). The 5-year survival rate in cervix lesions more than 4 cm and those less than or equal to 4 cm in stage Ⅱ was 63.9% and 79.3%,respectively, with statistically significant difference (P<0.05). The 5-year survival rate of the patients with squamous carcinoma in stage Ⅱ was 77.0% and that with low differentiated squamous carcinoma was 64.0%respectively. Twenty-three (4.5%) out of 512 suffered from post-radiotherapy rectitis, 18 (3.5%) cystitis.Conclusion: the survival rate of the patients with cervix carcinoma subject to radiotherapy is stabilized to 65%. The diameter and pathological classes affect survival rate, respectively. Low radiotherapy dose decrease complications.

  1. Cell-mediated infection of cervix derived epithelial cells with primary isolates of human immunodeficiency virus.

    Tan, X; Phillips, D M

    1996-01-01

    We have previously demonstrated that HIV-infected transformed T-cells or monocytes adhere to monolayers of CD4-negative epithelial cells. Adhesion is soon followed by budding of HIV from infected mononuclear cells onto the surface of epithelial cells. Epithelial cells subsequently take up virus and become productively infected. Based on these findings, we proposed that sexual transmission of HIV may involve cell-mediated infection of intact mucosal epithelia of the urogenital tract. However, it has become increasingly clear that primary cells and HIV strains isolated from patients are more appropriate models for HIV infection than established cell lines and lab strains of virus. In the studies described here, we infected cervix-derived epithelial monolayers with primary monocytes infected with patient isolates of non-syncytial inducing (NSI) macrophage-tropic strains of HIV. Under the culture conditions employed, HIV-infected primary monocytes do not remain adherent to the apical surface of the epithelium, as did HIV-infected transformed cells. Instead, following adherence, the primary cells migrate between epithelial cells. Virus is secreted from a pseudopod as HIV-infected primary monocytes pass between cells of the epithelium. Productive infection of the epithelium was detected by p24 ELISA and PCR Southern blot analysis. Infection can be blocked by sera from HIV-seropositive individuals or by certain sulfated polysaccharides. These findings support the supposition that transmission of HIV may occur via cell-mediated infection of intact epithelia. The observations also hint at the possibility that-HIV-infected monocyte/macrophages in semen or cervical-vaginal secretions could cross intact epithelia by passing between epithelial cells. Blocking studies suggest that it may be possible to inhibit sexual transmission of HIV either by antibodies in genital tract secretions or by a topical formulation containing certain sulfated polysaccharides.

    Human papillomavirus (HPV) DNA sequences coexisting with HPV16 and HPV45 were cloned from an invasive cervical carcinoma. The cloned HPV was shown to be a novel type, named HPV66, and is related to HPV56 (an HPV detected in cervical cancer). After screening 160 anogenital biopsies, four specimens exhibited histological features of intraepithelial neoplasia and contained HPV66 sequences. Of these, three were found to be associated with another HPV type.

    Vismodegib is a novel, small-molecule inhibitor of smoothened, a key component of the hedgehog signaling pathway. Increased hedgehog pathway signaling is critical in the development of hereditary and spontaneous basal cell carcinomas of the skin, and has been implicated in the development of a number of other tumors. In preclinical models, vismodegib demonstrated potent antitumor activity in hedgehog-dependent tumors, particularly basal cell carcinomas. Clinically, phase I and II studies showed dramatic anticancer activity in patients with advanced basal cell carcinomas. In January 2012, vismodegib was approved by the FDA for the treatment of unresectable or metastatic basal cell carcinomas of the skin.

Sixty-four (stage II - 35/64; stage III - 29/64 patients of cervical cancer were treated with combination of external beam radiotherapy (EBRT and low dose rate intracavitary brachytherapy (ICBT. The cumulative BED was calculated at Point A (BED 10 ; and bladder, rectal reference points (BED 2.5 using the linear-quadratic BED equations. The local control (LC rate and 5-year disease-free survival (DFS rate in patients of stage II were comparable for BED 10 < 84.5 and BED 10 > 84.5 but were much higher for BED 10 > 84.5 than BED 10 < 84.5 ( P < 0.01 in stage III patients. In the stage II patients, The LC rate and 5-year DFS rate were comparable for OTT < 50 days and for OTT> 50 days but were much higher in stage III patients with OTT < 50 than OTT> 50 days ( P < 0.001. It was also observed that patients who received BED 2.5 < 105 had lesser rectal ( P < 0.001 and bladder complications than BED 2.5 > 105. Higher rectal complication-free survival (CFS R rate, bladder complication-free survival (CFS B rate and all-type late complication-free survival rate were observed in patients who received BED 2.5 < 105 than BED 2.5 > 105. A balanced, optimal and justified radiotherapy treatment schedule to deliver higher BED 10 (>84.5 and lower BED 2.5 (< 105 in lesser OTT (< 50 days is essential in carcinoma cervix to expect a better treatment outcome in all respects.

    Full Text Available Background: Although conventional four- field radiotherapy based on bony landmarks has been traditionally used, areas of geographical miss due to individual variation in pelvic anatomy have been identified with advanced imaging techniques. AIMS: The primary aim of this study is to evaluate the geographical miss in patientswhen using the conventional four-field planningplanning and to find out the impact of 3-D conformal CT based in patients with locally advanced carcinoma cervix.Materials and Methods: In 50 patients, target volume delineation was done on planning computed tomography (CT scans, according to guidelines by Taylor et al. Patients were treated with modified four field plan, except for the superior, where field border was kept at L4-L5 interspace A dosimetric comparison was done between the conventional four-field based on bony landmarks and the target volume delineated on computed tomography. The disease free survival, pelvic and para aortic nodal free survival, distant failures free survival were calculated using Kaplan Meir Product Limit Method. Results: Patients were followed-up for a median period of 11 months. The median V95 for conventional and modified extended four field plans were 89.4% and 91.3% respectively. Patients with V95 for modified extended pelvic fields less than 91.3% had a trend toward inferior disease free survival (mean DFS 9.8 vs. 13.9 months though the difference was not statistically significant log rank test.Conclusions: Our preliminary data shows trend toward lower DFS in patients with inadequate target volume coverage. We recommend routine use of CT based planning for four field technique.

    Full Text Available Background: The primary aim of the study was to evaluate the effectiveness of sulfasalazine in reducing the incidence of acute radiation-induced enteritis in carcinoma cervix patients receiving pelvic external beam radiotherapy along with concurrent cisplatin-based chemotherapy. Materials and Methods: Between November 2011 and July 2012 a total of 98 patients of locoregionally advanced carcinoma of cervix (49 each in study and control arms were enrolled in this study. Patients in both the arms were treated with whole pelvis external beam radiotherapy with total dose of 50 Gy in conventional fractionation. Along with this inj. cisplatin was given concurrently at the dose of 40 mg/m 2 of body surface area every week during radiation for 5 weeks. Concurrent chemoradiation was followed by brachytherapy after a gap of 2 weeks. Patients in the study arm also received tablet sulfasalazine 1,000 mg orally twice daily from the day of starting of radiotherapy to 1 week after completion of treatment. Weekly follow-up of all patients to assess acute toxicities was done using common toxicity criteria version 4.0 (CTC v4.0 toxicity scores. Data analysis was carried out by SPSS version 20.0 software. Results: Incidence of grade II or higher grade, lower gastrointestinal toxicity was 19.14% (09/47 in study arm and 41.66% (20/48 in control arm which was statistically significant (P = 0.017. Conclusion: The study shows that sulfasalazine can significantly reduce the acute radiation-induced diarrhea (ARID in patients undergoing whole pelvis external beam radiotherapy for carcinoma cervix. The drug is safe, cheap, and readily available.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Squamous cell carcinoma (SCC) is a relatively common, malignant neoplasm of dogs and cats that can arise in a variety of locations. The gross appearance of SCC can be variable and nonspecific, so definitive diagnosis requires microscopic examination of the tissue (cytology or histology). Several treatment modalities exist, but surgical excision, if possible, is regarded as the best treatment option. Early diagnosis and treatment of SCC are key because small, early-stage tumors are the most amenable to treatment and carry the best prognosis.

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

Objective To compare the expressive patterns of the isoantigenic determinants of histo-blood groups ABH and Lewis in squamous and simple epithelium and in precursors and cancers of the cervix. Methods A total of 36 lesions and neoplasms (10 LG-SIL, 16 HG-SIL and 10 invasive carcinomas have been studied with immunohistochemical techniques, using monoclonal antibodies (MoAb BG1 to BG8 for precursor chains, blood-group ABH and Lewis group Lea, Leb, Lex, and Ley, and four types of lectins. In addition, we have studied the expression of p53 protein and PCNA, establishing the rate of proliferation of each lesion. Using PCR techniques, we have also detected part of the intron of the E6 gene of HPV-16. Results In the invasive cervical carcinomas, we observed a loss of expression of the Lex antigen (p y antigens. With PCNA, we established a proliferative rate which tended to be greater in relation to the progression of the cervix neoplasms. Conclusion These results indicate that there is a relation between the losses of histo-blood groups and the progression of the squamous intraepithelial lesions.

    Objective To study the relationship between cell proliferation and apoptosis in cervical carcinoma and its clinical significance.Methods The cell proliferation and apoptosis of cervical epithelial cells in archival formalin-fixed,paraffin-embedded tissue sections of normal cervix ,cervical intraepithelial neoplasms(CN) and cervical squamous carcinoma were tested by using immunohistochemistry assay and DNA nick end-labeling technigue.The proliferation index(PI) and apoptosis index(AI) were calculated and their correlation with clinical and pathological data was analyzed. Results PI was gradually increased,but the AI and AI/PI ratio decreased from normal cervical epithelium,CIN to cervical carcinoma. There was no significant relationship among cell proliferation,apoptosis,clinical stages and pathological grades.High AI was always asso-ciated with a poor prognosis of the patients. Conclusion Cell proliferation and apoptosis allow to distinguish among normal epithelium,CIN and cervical carcinoma and are useful for the assessment of the malignant potential of tumor tissues.

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

    Full Text Available Background : Cancer of cervix is the most common form of cancer in females of developing countries. Cervical cancer is the best example of common human malignancy with a proven infectious etiology. The data linking human papilloma virus (HPV infection with the epidemiology and pathogenesis of cervical neoplasia is convincing. There are various methods for detection of HPV like immunohistochemistry, polymerase chain reaction, liquid phase hybridization (hybrid capture test, in situ hybridization etc. Materials and Methods: We studied the profile of precancerous and cancerous lesions of uterine cervix and correlated human papilloma virus (HPV presence with precancerous and cancerous lesions of uterine cervix by immunohistochemistry. Total 50 cases were first studied, analyzed, and classified histologically and then immunohistochemistry was done. Results : Majority of the cases 36/50 (72% under study are squamous cell carcinomas, which is the most common carcinoma found in the uterine cervix. HPV positivity for all cases of cervical carcinoma was found to be 34.7% (16/46 cases, for carcinoma in situ, it was 50% (2/4 cases. It can be thus hypothesized that with decreasing differentiation, there is loss of expression of HPV in the cervical epithelial cells. Conclusion: To conclude, though this study confirms the correlation of HPV presence with precancerous and cancerous lesions of uterine cervix, it also suggests that there must be other co-factors involved in cervical carcinogenesis as well.

    Full Text Available Abstract Background Cervical uterine epithelial cells maintain a physiological and pathogen-free milieu in the female mammalian reproductive tract and are involved in sperm-epithelium interaction. Easily accessible, differentiated model systems of the cervical epithelium are not yet available to elucidate the underlying molecular mechanisms within these highly specialized cells. Therefore, the aim of the study was to establish a cell culture of the porcine cervical epithelium representing in vivo-like properties of the tissue. Results We tested different isolation methods and culture conditions and validated purity of the cultured cells by immunohistochemistry against keratins. We could reproducibly culture pure epithelial cells from cervical tissue explants. Based on a morphology score and the WST-1 Proliferation Assay, we optimized the growth medium composition. Primary porcine cervical cells performed best in conditioned Ham's F-12, containing 10% FCS, EGF and insulin. After cultivation in an air-liquid interface for three weeks, the cells showed a discontinuously multilayered phenotype. Finally, differentiation was validated via immunohistochemistry against beta catenin. Mucopolysaccharide production could be shown via alcian blue staining. Conclusions We provide the first suitable protocol to establish a differentiated porcine epithelial model of the cervix uteri, based on easily accessible cells using slaughterhouse material.

    In carcinoma, such as of the lung, the histological subtype is important to select an appropriate therapeutic strategy for patients. However, carcinomas with poor differentiation cannot always be distinguished on the basis of morphology alone nor on clinical findings. Hence, delineation of poorly differentiated adenocarcinoma and squamous cell carcinoma, the 2 most common epithelial-origin carcinomas, is pivotal for selection of optimum therapy. Herein, we explored the potential utility of trefoil factor 3 (TFF3) as a biomarker for primary lung adenocarcinoma and extrapulmonary adenocarcinomas derived from different organs. We observed that 90.9% of lung adenocarcinomas were TFF3-positive, whereas no expression of TFF3 was observed in squamous cell carcinomas. The subtype of lung carcinoma was confirmed by four established biomarkers, cytokeratin 7 and thyroid transcription factor 1 for adenocarcinoma and P63 and cytokeratin 5/6 for squamous cell carcinoma. Furthermore, expression of TFF3 mRNA was observed by quantitative PCR in all of 11 human lung adenocarcinoma cell lines and highly correlated with markers of the adenocarcinomatous lineage. In contrast, little or no expression of TFF3 was observed in 4 lung squamous cell carcinoma cell lines. By use of forced expression, or siRNA-mediated depletion of TFF3, we determined that TFF3 appeared to maintain rather than promote glandular differentiation of lung carcinoma cells. In addition, TFF3 expression was also determined in adenocarcinomas from colorectum, stomach, cervix, esophagus, and larynx. Among all these extrapulmonary carcinomas, 93.7% of adenocarcinomas exhibited TFF3 positivity, whereas only 2.9% of squamous cell carcinomas were TFF3-positive. Totally, 92.9% of both pulmonary and extrapulmonary adenocarcinomas exhibited TFF3 positivity, whereas only 1.5% of squamous cell carcinomas were TFF3-positive. In conclusion, TFF3 is preferentially expressed in adenocarcinoma and may function as an additional

    The role of p53 as modulator of OxPhos and glycolysis was analyzed in HeLa-L (cells containing negligible p53 protein levels) and HeLa-H (p53-overexpressing) human cervix cancer cells under normoxia and hypoxia. In normoxia, functional p53, mitochondrial enzyme contents, mitochondrial electrical potential (ΔΨm) and OxPhos flux increased in HeLa-H vs. HeLa-L cells; whereas their glycolytic enzyme contents and glycolysis flux were unchanged. OxPhos provided more than 70% of the cellular ATP and proliferation was abolished by anti-mitochondrial drugs in HeLa-H cells. In hypoxia, both cell proliferations were suppressed, but HeLa-H cells exhibited a significant decrease in OxPhos protein contents, ΔΨm and OxPhos flux. Although glycolytic function was also diminished vs. HeLa-L cells in hypoxia, glycolysis provided more than 60% of cellular ATP in HeLa-H cells. The energy metabolism phenotype of HeLa-H cells was reverted to that of HeLa-L cells by incubating with pifithrin-α, a p53-inhibitor. In normoxia, the energy metabolism phenotype of breast cancer MCF-7 cells was similar to that of HeLa-H cells, whereas p53shRNAMCF-7 cells resembled the HeLa-L cell phenotype. In hypoxia, autophagy proteins and lysosomes contents increased 2-5 times in HeLa-H cells suggesting mitophagy activation. These results indicated that under normoxia p53 up-regulated OxPhos without affecting glycolysis, whereas under hypoxia, p53 down-regulated both OxPhos (severely) and glycolysis (weakly). These p53 effects appeared mediated by the formation of p53-HIF-1α complexes. Therefore, p53 exerts a dual and contrasting regulatory role on cancer energy metabolism, depending on the O₂level.

    Full Text Available Purpose: To assess bladder and rectum doses in relation to body mass index of patients undergoing high dose rate brachytherapy for the treatment of carcinoma of the cervix.Methods: The cohort consists of fifty subjects with carcinoma of the uterine cervix presented with grade II and III. Patient’s height and weight was measured before the insertion of applicator in situ. Body mass index (BMI of the patient was calculated in accordance to World Health Organization definition (weight in Kg/ height in m2. Adequacy of position and orientation of the applicator was confirmed with the help of orthogonal X-ray images and the same were transferred to the treatment planning system (TPS to generate treatment plan. Prescription doses were optimized to Point A and to reference lines placed at 0.5 cm apart from the surface of ovoids. The following dose reference points were identified on orthogonal x-ray images for analysis using the rectal marker and Foleys bulb inflated with radio opaque dye Rectal points at the level of femoral heads (RL and pubis symphysis (RLP, Anorectum Junction (AR Jn point and Rectosigmoid (RS point and Bladder point (BL. Pearson regression analysis was used to analyze data from TPS.Results: The mean BMI was 22.7 kg/m2 and average age was 49.9 years. Analysis showed that RL point dose and BMI were inversely correlated with a coefficient -0.45 (p = 0.001. The trend continued along the rectal tube in cranio-caudal direction, as RLP and AR Jn points showed inversion co-efficiency with increase in BMI,-0.48 (p < 0.01 and -0.51 (p < 0.01 respectively. Bladder point showed weak positive correlation to BMI, 0.12 (p = 0.38.Conclusion: Significant rectal dose reduction is observed with increase in BMI. Bladder dose did not show statistically significant correlation with BMI. Based on the findings, BMI constitutes a confounding factor in the treatment of carcinoma of cervix.

    West Africa has one of the highest incidence rates of carcinoma of the cervix in the world. The vast majority of women do not have access to screening or disease treatment, leading to presentation at advanced stages and to high mortality rates. Compounding this problem is the lack of radiation treatment facilities in Senegal and many other parts of the African continent. Senegal, a country of 13 million people, had a single {sup 60}Co teletherapy unit before our involvement and no brachytherapy capabilities. Radiating Hope, a nonprofit organization whose mission is to provide radiation therapy equipment to countries in the developing world, provided a high-dose-rate afterloading unit to the cancer center for curative cervical cancer treatment. Here we describe the implementation of high-dose-rate brachytherapy in Senegal requiring a nonstandard fractionation schedule and a novel treatment planning approach as a possible blueprint to providing this technology to other developing countries.

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

Materials and Methods: Between January 1997 to December 2001, a total of 550 newly diagnosed cases of carcinoma of the uterine cervix were reported in the department. All cases were staged according to the International Federation of Gynecologists and Oncologists (FIGO staging system, but for analytical convenience, the staging was limited to stages I, II, III, and IV. Out of the 550 cases, 214 completed radical radiotherapy (EBRT + HDR-ICRT and were retrospectively analyzed for presence of local residual disease, local recurrence, distant metastases, radiation reactions, and disease-free survival. Results: There were 7 (3.27%, 88 (41.1%, 101 (47.1%, and 18 (8.4% patients in stage I, II, III, and IV, respectively. The median follow-up time for all patients was 43 months (range: 3-93 months and for patients who were disease free till the last follow-up it was 59 months (range: 24-93 months. The overall treatment time (OTT ranged from 52 to 73 days (median 61 days. The 5-year disease-free mean survival rate was 58%, 44%, 33%, and 15%, with 95% confidence interval of 48 to 68, 37 to 51, 24 to 35, and 6 to 24 for stages I, II, III, and IV, respectively. There were 62 (28.97% cases with local residual disease, 35 (16.3% developed local recurrence/distant metastases, 17 (7.9% developed distant metastases, and 9 (4.2% had local recurrence as well. Discussion and Conclusion: The overall outcome was poor in advanced stage disease, but might be improved by increasing the total dose, decreasing overall duration of treatment, and by adding chemotherapy in patients with disease limited to the pelvis.

    Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine carcinoma of the skin. Although it is 40 times less common than malignant melanoma, its mortality is much higher compared to melanoma. From 1986 to 2001 there was rapidly increasing incidence in reported cases of MCC, with a tripling in the rate over this 15-year period. The vast majority of MCC presents on sun-exposed skin. The head and neck area is the most common site of tumor occurrence. We present 70-year old female patient with painless red-colored nodule, size 2 x 2 x 2 cm on the dorsal side of mid left forearm. The surgical excision with negative margins was performed, and pathohistological analysis confirmed Merkel cell carcinoma. Sentinel lymph node biopsy was negative. In conclusion, as MCC is a very aggressive rare skin carcinoma with lethal outcome, it should be mandatory to perform biopsies of any suspected skin lesion.

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

    Renal cell carcinoma is an aggressive disease with a high rate of mortality. It is known to metastasize to the lung, liver, bone and brain. However, manifestation through lymphatic spread to the lungs is rare. Lymphangitic carcinomatosis is commonly observed in malignancies of the breast, lung, pancreas, colon and cervix. It is unusual to observe lymphangitic carcinomatosis of the lungs due to renal cell carcinoma. Lymphangitic carcinomatosis of the lungs may result in severe respiratory distress and may be the direct cause of death. Currently, there are no known modalities of preventing or slowing lymphangitic carcinomatosis besides treating the primary tumor. However, early detection may change the course of the disease and may prolong survival. This is compounded by the difficulty involved in diagnosing lymphangitic carcinomatosis of the lung which frequently involves lung biopsy. Immunohistochemical studies are often used in conjunction with regular histochemistry in ascertaining the primary tumor and in differentiating it from pulmonary metastasis. In this case report, we describe the presentation and clinical course of renal cell carcinoma in a patient which manifested as lymphangitis carcinomatosa of the lungs. The patient underwent surgical resection of the primary tumor with lymph node resection but presented with a fulminant lymphangitic carcinomatosis of the lungs within two weeks. Immunohistochemistry of the tissue obtained by the biopsy confirmed the diagnosis which was subsequently corroborated during his autopsy. This case illustrates the necessity of an urgent follow-up of chemotherapy and immunotherapy in such patients.

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

    To clarify the significance of p150 expression, 102 gastric carcinomas were immunohistochemically investigated and 14 fresh samples of the cancer were analyzed with the immunoblot method. Tumor cell apoptosis was assessed by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-digoxigenin nick end labeling (TUNEL). Both Ki-67 antigen and p53 expression were analyzed immunohistochemically. Eighty-six out of 102 (85%) gastric cancers stained positively for p150. All 14 tumors analyzed by Western blotting overexpressed p150. Statistical analysis revealed a close association between p150 overexpression and the clinicopathologic parameters of gastric cancer. All well-differentiated cancers showed high p150 expression (p cervix and esophagus carcinoma, when tumors progress to high malignancy and metastasis, p150 begins to regress and then breaks down. A good correlation of p150 expression, but not p53 expression, with tumor cell apoptosis could be demonstrated (p Ki-67 labeling index, i.e., the index for a proliferative marker, showed no correlation with either p150 or p53 expression. The results suggest that p150 may be a new early tumor marker for gastric carcinoma similar to that for esophagus and cervix carcinoma.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Full Text Available Objectives: To compare the presentation of cervical cancer and the treatment modalities received by the patients at a semi-urban/rural area of Western India with that of published literature from urban centers. Materials and Methods: We conducted a retrospective analysis of patients with cervical cancer who presented at a semi-urban/rural cancer center between 2010 and 2013. A total of 141 patients with the median age of 51 years (25-81 were studied. The demographic and clinical variables included age, annual family income, profession, comorbidities, baseline hemoglobin, prior screening, clinical stage, treatment administered, and complications. The pathological variables included tumor type and grade. Results: In our study, all patients presented with vaginal bleeding. Majority of the patients (51 patients, 37.7% had Stage 3B disease. Since majority presented at later stages (Stage 3B, chemotherapy-radiotherapy was the most common treatment modality used in our population. On histopathology, 127 patients (90% had squamous cell carcinoma while 14 patients (10% had adenocarcinoma. In 96 patients (68%, the tumor grade was not known while it was a high, intermediate, and low grade in 6 (4%, 18 (13%, and 21 (15% patients, respectively. The follow-up data of our study were not adequate; hence, the long-term survival results could not be presented. Conclusion: Patients in rural India setting present at later stages which could be improved by creating awareness, improving their personal hygiene, and adequate screening.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated.

    Case: A 63-year-old male presented with unintentional weight loss of 20 pounds over a 4-month duration. He reported loss of appetite, intermittent post-prandial nausea, bloating and early satiety. He also complained of dyspepsia and had been treated for reflux during the previous 2 years. He denied vomiting, dysphagia, odynophagia, abdominal pain, melena, hematochezia, or alterations in bowel habits. Additionally, he denied fevers, night sweats, cough, or dyspnea. He quit smoking 25 years ago, and denied alcohol use. His past medical history was significant for basal cell carcinoma treated with local curative therapy and he was without recurrence on surveillance. Pertinent family history included a paternal uncle with lung cancer at the age of 74. Physical examination was unremarkable except for occult heme-positive stools. Laboratory evaluation revealed elevated liver enzymes (ALT-112, AST-81, AlkPhos-364). CT scan of the chest, abdomen and pelvis showed diffuse heterogeneous liver with extensive nodularity, raising the concern for metastases. Serum tumor-markers: PSA, CEA, CA 19-9, and AFP were all within normal limits. Screening colonoscopy was normal, but esophagogastroduodenoscopy revealed a malignant-appearing ulcerative lesion involving the gastro-esophageal junction and gastric cardia. Pathology confirmed an invasive gastric large cell neuroendocrine carcinoma. Ultrasound-guided fine needle aspiration of a hepatic lesion revealed malignant cells with cytologic features consistent with large-cell type carcinoma and positive immunostaining for synaptophysin favoring neuroendocrine differentiation. A PET-CT demonstrated intense diffuse FDG uptake of the liver, suggesting diffuse hepatic parenchymal infiltration by tumor. There were multiple foci of intense osseous FDG uptake with corresponding osteolytic lesions seen on CT scan. The remaining intra-abdominal and intra-thoracic structures were unremarkable. The patient will receive palliative systemic therapy

    To investigate the expression and the relationship of P16INK4a and sonic hedgehog signal pathway in cervical squamous cell carcinoma and its precursor lesions. The expression of P16INK4a, Smo, Ptch and Gli in different HPV types positive cell lines were detected by Western-blot. A tissue microarray constructed with 20 normal cervical tissues and 100 uterine cervical cancers and related lesions (28 squamous cell carcinomas, 26 cervical intraepithelial neoplasia (CIN) Ⅲ, 16 CIN Ⅱ , 12 CIN Ⅰ , 18 tumor-adjacent tissue specimens) was immunohistochemically analyzed with anti- P16INK4a, Shh, Patched (Ptch), Smoothened (Smo), Gli antibodies. The correlation between their expressions was analyzed. There was no significant difference among different HPV type cell lines regarding the expression of P16INK4a and Shh, Ptch and Gli proteins(P > 0.05). The expression of P16INK4a and the Hh-signaling molecules was greatly enhanced in cervical carcinoma tissues, compared with that in normal epithelium and tumor-adjacent tissues (P 0.05), whereas, in case of P16INK4a, Shh, Smo, and Gli, the differences among CIN Ⅰ , CIN Ⅱ and CIN Ⅲ were significant (P < 0.05). The expression of P16INK4a protein was significantly correlated with that of Shh, Smo and Gli protein in CIN Ⅱ -CIN Ⅲ and cervical carcinoma and was correlated with that of Shh, Smo only in carcinoma tissue. P16INK4a and the Hh-Gli signaling pathways were extensively activated in the development and evolution of cervical cancer, and the overexpression of P16INK4a was correlated with Hh-signaling pathways. The abnormal Hh-signaling pathways maybe much associated with Smo protein overexpression induced by Shh, which can upregulate the expression of Gli protein.%探讨P16INK4a及Sonic hedgehog (Hh-Gli)信号通路蛋白在宫颈癌及癌前病变(CIN)中的表达相关性及其意义.采用Western-blot方法检测HPV16阳性及HPV18阳性宫颈癌细胞系P16INK4a及Hh-Gli信号通路蛋白Smo、Ptch及Gli表达.

    The cell interrelations, and cellular attachment to the stroma in normal columnar epithelium and adenocarcinoma of the cervix uteri were examined by transmission and scanning electron microscopy. The application of rapid enzymatic digestion technique allows to visualize the topography of cell membranes, otherwise disguised in ordinary conditions. Four types of disordered epithelial sheets characterized by different apical, lateral and basal cell surface changes are described. Various alterations in morphology of the basement membrane and adjacent conjunctive tissue are associated with the tumor appearance. Marked deviations in cell-stroma contact may lead to the inversion of cell polarity revealed in cervical adenocarcinoma: cellular parts adjoining to stroma acquire characteristic features of the apical pole.

    Primary malignant lymphoma of the uterine cervix is a rare disease, and the therapeutic strategy has not been clearly established. A 45-year old woman presented with vaginal bleeding and hypermenorrhea in January 2012. Physical examination revealed a mass in the pelvic cavity approximately the size of a neonate's head. Pelvic magnetic resonance imaging(MRI) showed a solid mass 11 cm in size in the uterine cervix with homogeneous low intensity on T1-weighted images, iso-high intensity on T2-weighted images, and heterogeneous iso-high intensity on gadolinium-diethylenetriaminepentaacetate(Gd- DTPA)-enhanced images. Multiple lymphadenopathy were also detected in the pelvis. The Papanicolaou smear indicated class 5 cervical cytology, and a subsequent histological examination by a punch biopsy of the cervix showed diffuse infiltration of medium- to large-sized mononuclear cells that stained positive for CD20 and CD79a and negative for CD3, CD5, and EBER. Bone marrow biopsy revealed no abnormality. Positron emission tomography-computed tomography(PET-CT)showed strong fluorodeoxyglucose(FDG)accumulation in the uterine cervix mass, and in the pelvic and right inguinal lymphadenopathy. The patient was diagnosed with diffuse large B-cell lymphoma of the uterine cervix, Ann Arbor stage II AE. She was successfully treated with 8 courses of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone(R-CHOP) chemotherapy, and maintains a complete remission.

    2004-01-01

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

    Full Text Available Purpose: In clinical practice, radiation therapy often fails in cervical carcinoma stage IIIB and there is a need to develop a predictive assay for prognosis of radiation treatment outcome in cancer patient. We have attempted to evaluate the relevance of changes in Membrane Fluidity (MF and associated apoptotic cell death in cervical cancer cells after first fractionated dose of radiation therapy to treatment outcome of stage IIIB cervical carcinoma patients. Materials and Methods: Biopsies of 15 patients with histologically proven cervix cancer were collected from the patients before and 24 h after first fractionated radiation dose of 2 grays (Gy. Cell suspension made in Dulbecco′s Modified Eagle′s Medium (DMEM were used for further investigations and cell suspension of cervix cancer patient were used to measure MF by fluorescence polarization method and apoptotic index (AI was determined by Tdt dUTP Nucleotide End Labeling (TUNEL assay. Results: A substantial increase in MF and AI was observed in cervical cancer cells irradiated ex vivo . A significant correlation ( P < 0.001 was found between the changes in AI after first fractionated dose of radiotherapy and treatment outcome of patients. No significant correlation ( P > 0.1 was detected between changes in MF and treatment outcome of patients. Conclusion: Preliminary results showed significant change in MF and a marked increase in percentage apoptosis of cervix cancer cells irradiated ex vivo . The changes in AI after first fractionated dose of radiotherapy in cervical carcinoma patients may provide a predictor of prognosis for radiotherapy in uterine cervical carcinoma patients.

    Full Text Available Merkel cell carcinoma (MCC of the skin is a rare, aggressive, malignant neuroendocrine neoplasm. The tumor classically demonstrates positive immunohistochemistry (IHC staining for chromogranin A(ChrA, cytokeratin 20 (CK20, neuron specific enolase (NSE and/or achaete-acute complex-like 1 (MASH1. The newly identified Merkel cell polyomavirus (MCPyV has been found to be associated with most MCC cases. The primary histologic differential diagnoses of cutaneous MCC is small cell primary bronchogenic carcinoma (SCLC; moreover, both are of neuroendocrine origin. SCLC accounts for approximately 10-15% of all primary lung cancer cases; this histologic subtype is a distinct entity with biological and oncological features distinct from non-small cell lung cancer (NSCLC. In contradistinction to MCC, SCLC is classically IHC positive for cytokeratin 7 (CK7 and transcription factor (TTF-1. Similar to SCLC, MCC cell lines may be classified into two different biochemical subgroups designated as Classic and Variant. In our review and case report, we aim to emphasize the importance of a multidisciplinary approach to the approach to this difficult differential diagnosis. We also aim to comment about features of the cells of origin of MCC and SCLC; to summarize the microscopic features of both tumors; and to review their respective epidemiologic, clinical, prognostic and treatment features. We want to emphasize the initial workup study of the differential diagnosis patient, including evaluating clinical lymph nodes, a clinical history of any respiratory abnormality, and chest radiogram. If a diagnosis of primary cutaneous MCC is confirmed, classic treatment includes excision of the primary tumor with wide margins, excision of a sentinel lymph node, and computed tomography, positron emission tomography and/or Fluorine-18-fluorodeoxyglucose positron emission tomography scan studies

    Previous studies have shown the involvement of the immune response in the progression of human uterine cervix cancer. The aim of this study was to determine the expression of Interleukin-2 (IL-2), IL-2 receptor (IL-2R) and Interleukin 10 (IL-10) in different grades of cervical intraepithelial neoplasias of the exocervix (CIN 1, 2 and 3), and its relationship with the serum cytokine profiles and human papilomavirus (HPV) infection status. Indirect immunofluorescence was used to study the expression of IL-2, IL-2R and IL-10 in human cervical samples from 50 patients and 9 normal controls. Serum IL-2, IL-2R and IL-10 were measured by ELISA and HPV DNA and HPV types were identified by PCR. Increased number of IL-2, IL-2R and IL-10 positive cells were observed in the cervix from patients with CIN, associated with the grades of dysplasia. A significant correlation was observed between IL-2 and IL-2R (p>0.0001), IL-2 and IL-10 (p>0.0001), as well as IL-10 and IL-2R (p>0.0001). Twenty percent of patients were HPV positive and 84% of those patients were tissue cytokine positive. These results suggest that IL-2, IL-2R and IL-10 tissue expression may play a role in the development of cervical intraepithelial dysplasias.

    Background Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Methods Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). Results The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. Conclusion The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    Full Text Available Background and Objectives: Acute hematological toxicities are an important cause of morbidity in patients receiving concurrent chemoradiation to pelvis in carcinoma cervix. The objective of this study was to evaluate the role of intensity-modulated radiotherapy (IMRT in reducing the dose to the bone marrow as compared with three-dimensional conformal radiotherapy (3DCRT and hence its impact on reducing the acute hematological toxicities. Materials and Methods: Eleven consecutive patients treated with IMRT and 12 patients treated with 3DCRT to the whole pelvis along with concurrent chemotherapy were selected. Bone marrow was delineated. V10 Gy, V20 Gy, V95%, and Dmean of bone marrow were recorded. Weekly blood counts were recorded and graded as per Common Terminology Criteria version 4.0 for all the patients. Results: The dose to the bone marrow V20 Gy was 206.78 ± 57.10 cc (75% and 251.70 ± 40.45 cc (91% for IMRT and 3DCRT, respectively (P = 0.04 and V95% was 23.30 ± 8.34% and 46.76 ± 6.71% for IMRT and 3DCRT, respectively (P = 0.001. The grade of toxicities during each week did not show the difference in either arm. However, the total count and Neutrophil counts during the 2nd week showed statistical significance between IMRT and 3DCRT. Conclusion: IMRT significantly reduces the dose to the bone marrow as compared to 3DCRT. The reduction of the dose did not translate into a decrease in acute hematological toxicities. Concurrent platinum-based chemotherapy is the probable cause for the hematological toxicities.

    Background and Purpose: although the standard of care for patients with locally advanced uterine cervix carcinoma is cisplatin-(CDDP-)based chemotherapy and irradiation (RT), the optimal regimen remains to be elucidated. A phase I/II study was conducted to evaluate the dose limiting toxicity (DLT) and the maximum tolerated dose (MTD) of liposomal doxorubicin (Caelyx) combined with CDDP and RT for cervical cancer. Patients and Methods: 24 patients with stage IIB-IVA were enrolled (Table 1). They all received external RT (up to 50.4 Gy) and two medium-dose rate (MDR) brachytherapy implants (20 Gy each at point A). The Caelyx starting dose of 7 mg/m{sup 2}/week was increased in 5-mg/m{sup 2} increments to two levels. The standard dose of CDDP was 20-25 mg/m{sup 2}/week. Results: concurrent chemoradiation (CCRT) sequelae and the DLTs (grade 3 myelotoxicity and grade 3 proctitis in five patients treated at the 17 mg/m{sup 2}/week Caelyx dose level) are shown in Tables 2, 3, 4, and 5. After a median follow-up time of 17.2 months (range 4-36 months), four patients had died, 15 showed no evidence of progressive disease, and five (20.8%, 95% confidence interval [CI]: 12.5-29.1%) were alive with relapse (Figure 1). There were seven complete (29.1%, 95% CI: 19.8-38.4%) and 17 partial clinical responses (95% CI: 61.1-80.1%). The median progression-free survival was 10.4 months. Causes of death were local regional failure with or without paraaortic node relapse combined with distant metastases (Table 6). Conclusion: The MTD of Caelyx given concurrently with CDDP and RT was determined at the 12 mg/m{sup 2}/week dose level. The above CCRT schema is a well-tolerated regimen, easy to administer in ambulatory patients, and results appear promising. (orig.)

    Full Text Available Purpose: To assess the dosimetry to organs at risk (OARs in lithotomy position with a planned time-dose pattern obtained from supine position. Methods: The sample consists of thirty patients with carcinoma of the uterine cervix, Stage II and III. Patients often feel discomfort in supine position (S position when compared to lithotomy position (M position due to relaxation of pelvic floor muscles after the insertion of applicator (tandem and ovoids or before delivery of the treatment. Each patient was imaged with orthogonal X- ray radiographs simultaneously in two positions, i.e. S position and M position. Dwell time and dwell position pattern obtained from the optimized plan in S position was used to generate plan in M position. Following dose reference points (point A, pelvic wall points, bladder points, rectal, anorectum (AR point and rectosigmoid (RS point points were identified for analysis in S and M positions. The dosimetric data for reference points generated by the Brachyvision TPS was analyzed.Results: Pelvic wall points registered lower doses in M position when compared to S position. Mean doses for right pelvic wall point (RPW and left pelvic wall point (LPW were reduced by -10.02 % and -11.5% in M position, respectively. International Commission on Radiation Units and Measurements (ICRU bladder point also registered lower doses in M position with a mean dose of -6.8%. Rectal point showed dose reduction by mean of -6.4%. AR and RS points showed an increased dose in M position by a mean of 16.5% and 10%, respectively. Conclusion: Current dosimetry procedure serves as a model with time-dose pattern planned for S position, but delivered in M position, without dose optimization. Prioritization of comfort and position can be considered in conjunction with optimization of dose.

    Full Text Available Primary neuroendocrine tumors of the female genital tract have been described in the cervix, ovaries and uterus. Large cell neuroendocrine carcinoma (LCNC of the uterine corpus is the least common and appears to behave the most aggressively. We report a rare case of a large cell neuroendocrine tumor of the endometrium. These tumors are not well characterized, unlike neuroendocrine tumors of the uterine cervix, consequently, the optimal management remains still unclear. The treatment of our case consisted of surgery, radiotherapy, chemotherapy, and octreotide. Despite the aggressive treatment, the patient died of disease progression 12 months after the initial diagnosis. We discuss the diagnosis, prognosis, and treatment options for LCNC of the genital tract, and potential future therapeutics.

    2012-10-01

    Androgen-independent, human prostate carcinoma cells (DU145) develop into solid, carcinomatous xenotransplants on the diaphragm of nu/nu mice. Tumors encompass at least two poorly differentiated cell types: a rapidly dividing, eosinophilic cell comprises the main cell population and a few, but large basophilic cells able to invade the peritoneal stroma, the muscular tissue, lymph vessels. Poor cell contacts, intracytoplasmic lumina, and signet cells are noted. Lysosomal activities are reflected by entoses and programmed cell deaths forming cribriform carcinomas. In large tumors, degraded cells may align with others to facilitate formation of blood supply routes. Malignant cells would spread via ascites and through lymphatics.

    Squamous cell carcinomas of the anus are rare neoplasias that account for about 3% of large bowel tumours. Infections with human papillomaviruses are frequently detected in these cancers, suggesting that pathogenic pathways in anal carcinomas and in carcinomas of the uterine cervix are similar. Little is known regarding recurrent chromosomal aberrations in this subgroup of squamous cell carcinomas. We have applied comparative genomic hybridization to identify chromosomal gains and losses in 23 cases of anal carcinomas. A non-random copy number increase of chromosomes 17 and 19, and chromosome arm 3q was observed. Consistent losses were mapped to chromosome arms 4p, 11q, 13q and 18q. A majority of the tumours were aneuploid, and most of them showed increased proliferative activity as determined by staining for Ki-67 antigen. p53 expression was low or undetectable, and expression of p21/WAF-1 was increased in most tumours. Sixteen cancers were satisfactorily tested for the presence of HPV by consensus L1-primer polymerase chain reaction; nine were HPV positive, of which eight were positive for HPV 16.

    Full Text Available Tubulocystic renal cell carcinoma (TCRCC is a rare variant of renal cell carcinoma, which has distinct histology but there is some controversy about its association with papillary renal cell carcinoma (PRCC and cell of origin in literature. We report an 18-year-old girl with the rare TCRCC of kidney associated with PRCC with metastases to the para-aortic nodes. The patient presented with hematuria and a right renal mass with enlarged regional nodes for which a radical nephrectomy with retroperitoneal lymph node dissection was done. On gross examination, a solid cystic lesion involving the lower pole and middle pole of the kidney measuring 12x9x9 cm was seen along with an additional cystic lesion in upper pole of kidney. Microscopically the main tumor showed the typical histology of a tubulocystic carcinoma with multiple cysts filled with secretions lined by variably flattened epithelium with hobnailing of cells. The mass in the upper pole was a high-grade PRCC and the nodal metastases had morphology similar to this component. To conclude, at least a small but definite subset of TCRCC is associated with PRCC, and cases associated with PRCC do seem to have a higher propensity for nodal metastasis as in the case we report.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Membrane type 1-matrix metalloproteinase (MT1-MMP) participates in the activity of MMP-2, which correlates with cancer of uterine cervix. Single-nucleotide polymorphisms (SNPs) in promoter and exon of MT1-MMP may influence their binding with transcription factors and gene transcription. To date, no study reports the association of the MT1-MMP polymorphisms with cervical neoplasia. Therefore, we investigated the influence of the MT1-MMP gene polymorphisms on the susceptibility and clinicopathological variables of cervical neoplasia for women in Taiwan. We recruited 72 patients with cervical squamous cell carcinoma and 63 with high-grade dysplasia as 1 subgroup. Meanwhile, 280 control women were included as another subgroup. The SNPs rs1003349 (site -165), rs2236307 (+7096), and rs3751489 (+8153) as well as rs2236302 (site +6727) of MT1-MMP gene were determined by polymerase chain reaction (PCR)-restriction fragment length polymorphism and real-time PCR genotyping, respectively. Then, we correlated these SNPs and haplotypes with the development of cervical neoplasia and cancer clinicopathological variables. We found that women with CC genotype in rs2236307 SNP exhibited a more risk to develop cervical neoplasia as compared with those with wild genotype TT. Haplotypes -165 T, +6727 C, +7096 C, +8153 G or -165 G, +6727 G, +7096 T, and +8153 G and diplotypes including at least 1 type of these haplotypes of MT1-MMP gene showed a higher risk of cervical neoplasia. However, both haplotypes were not significantly correlated with the clinicopathological characteristics of cervical cancer. In conclusion, Taiwan women with variant homozygote CC (+7096) and haplotypes, TCCG and GGTG, of MT1-MMP exhibit more risk in developing cervical neoplasia.

    In diagnostic cytology, it has been advocated that molecular techniques will improve cytopathological diagnosis and may predict clinical course. Ancillary molecular techniques, however, can be applied only if a sufficient number of preparations are made from a single cell sample. We have developed the AgarCyto cell block procedure for multiple molecular diagnostic analyses on a single scraping from the uterine cervix. The optimized protocol includes primary fixation and transport in ethanol/carbowax, secondary fixation in Unifix, and embedding in 2% agarose and then in paraffin according to a standard protocol for biopsies. More than 20 microscopic specimens were produced from a single AgarCyto cell block, and standard laboratory protocols have been successfully applied for H&E staining, immunohistochemistry for Ki-67 and p53, and in situ hybridization for the centromere of human chromosome 1 and human papilloma virus Type 16. In addition, single AgarCyto sections yielded sufficient input DNA for specific HPV detection and typing by LiPA-PCR, and the protocol includes an option for DNA image cytometry. The AgarCyto cell block protocol is an excellent tool for inventory studies of diagnostic and potentially prognostic molecular markers of cervical cancer.

    In this study, we synthesized tungsten oxide (WO3) nanoplates, both crystallographic phases and the morphology of the samples were determined by powder x-ray diffraction and the scanning electron microscopy, respectively. The obtained data clarified that, the all prepared WO3·H2O samples were composed of large quantity of nanoplates. The cytotoxicity patterns of nanoplates were checked on both normal and cancer mammalian cell lines. Both nanoplates cytotoxicity did not exceed the 50 % inhibitory concentration (IC50) on the all normal tested cells even by using concentrations up to 1 mg/ml. In addition, orthorhombic tungsten oxide nanoplate was more potent against both Caco2 and Hela cells by showing inhibition percentages in cellular viability 64.749 and 72.27, respectively, and with cancer selectivity index reached 3.2 and 2.6 on both colon and cervix cancer, respectively. The anticancer effects of nanoplates were translated to alteration in both pro-apoptotic and anti-apoptotic genes expressions. Tungsten oxide nanoplates down regulated the expression of B cell lymphoma 2 (Bcl-2) and metalloproteinase-7 (MMP7) genes. In addition, orthorhombic tungsten oxide nanoplates showed more potentiation in IL2 and IL8 induction (40.43 pg/ml) and upregulation of TNF-α gene expression but with lower folds than Escherichia coli lipopolysaccharide (LPS) induction.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

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

    Full Text Available Background: Small-cell carcinoma (SCC and large-cell neuroendocrine carcinoma (LCNEC are uncommon in serous body cavity effusions. The purpose of this study is to examine the cytomorphological spectrum of SCC and LCNEC in body cavity serous fluids. Materials and Methods: We have 68 cases from 53 patients who had metastatic SCC or LCNEC diagnoses. All cytology slides and the available clinical data, histological follow-up, and ancillary studies were reviewed. Results: A total of 68 cases (60 pleural, 5 peritoneal, and 3 pericardial effusions from 53 patients with an average age of 73 years (age range 43-92 years were reported as diagnostic or suspicious of SCC (52 cases or LCNEC (16 cases. The primary site was lung in 56 cases, pancreas in 6 cases, and 2 cases each from cervix, colon, and the head and neck region. Of the 68 cases, 48 cases had no history of malignancy of the same type. Ancillary studies were used in 46 cases (68% including flow cytometric studies in 5 cases. There were three predominant cytomorphological patterns observed including small-cell clusters with prominent nuclear molding (33 cases, 49%, large-cell clusters mimicking non-small-cell carcinoma (18 cases, 26%, and single-cell pattern mimicking lymphoma (17 cases, 25%. Significant apoptosis was seen in 22 cases (33% and marked tumor cell cannibalism was seen in 11 cases (16%. Nucleoli were prominent in 16 cases (24%. The most frequent neuroendocrine markers performed were synaptophysin and chromogranin. Conclusions: The most common cytomorphologic patterns seen in body cavity effusions of SCC and LCNEC were small-cell clusters with nuclear molding. However, in 51% of the cases either a predominant single-cell pattern mimicking lymphoma or large-cell clusters mimicking non-small carcinoma were noted. In our experience, effusions were the first manifestation of disease in the majority of patients diagnosed with neuroendocrine carcinoma. Therefore, familiarity with the

    Full Text Available Surfactin is one of the most powerful biosurfactants that has been known so far. It is an acidic cyclic nonribosomal lipoheptapeptide that is produced by Bacillus subtilis. In this presentation we investigated different properties of surfactin C-15. The nanomicelle forming ability of surfactin C-15 in different aqueous environments with various ionic strengths was studied by scanning electron microscope. Surfactin second structure was investigated by Far-UV CD spectrum. Its hemolytic activity and cytotoxicity were measured by hemolysis and MTT assays, respectively. Surfactin formed spherical nanomicelles in distilled water and amorphous nanomicelles in PBS buffer . The hemolysis assay results indicated that HC50 of surfactin was 47 μM. Surfactin C-15 arrested growth of human cervix cancer HeLa cell line in a time- and dosage-dependent method, so that its IC50 at 16, 24, and 48h were 86.9, 73.1, and 50.2 μM, respectively.

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis.

    Full Text Available Large-cell neuroendocrine carcinomas of the lung are extremely rare. There are difficulties related to the diagnosis and treatment and there are no consensus because of the small number of studies. 65-year-old male patient presented with hemoptysis. Chest X-ray and thoracic computorized tomography scan showed a mass lesion and it could not be diagnosed by bronchoscopic biopsy and lavage. Lobectomy was performed due to the high value of standardized uptake value in positron emission tomography. Large cell neuroendocrine carcinoma was diagnosed with pathological evaluation and immunohistochemical study and after 20-month follow-up there was no recurrence. The diagnosis, treatment, and prognosis of large cell neuroendocrine carcinoma in the light of the literature is presented.

    Ovarian tumors have a low incidence in childhood, accounting for 1% of malignancies within the ages of 0-17 years. Small cell carcinoma of the ovary is a rare histology and historically has a poor prognosis. We report a case of an 11-year-old female diagnosed with small cell carcinoma of the ovary and hypercalcemia (SCCOHT). There was a strong family history of the disease, a reduction in the age of onset in the proband, and the absence of BRCA mutations. This case suggests the phenomenon of genetic anticipation in an ovarian cancer.

    We present a cohort of 8 renal carcinomas that displayed a variable (5%-95% extent) light microscopic appearance of renal angiomyoadenomatous tumor/clear cell papillary renal cell carcinoma (RAT/CCPRCC) without fulfilling the criteria for these tumors. All but 1 case predominantly (75%-95% extent) showed histopathologic features of conventional clear cell renal cell carcinoma. In 5 of 7 cases with mostly conventional clear renal cell carcinoma (CRCC) morphology, a diagnosis of CRCC was supported by the molecular genetic findings (presence of von Hippel-Lindau tumor suppressor [VHL] mutation and/or VHL promoter methylation and/or loss of heterozygosity [LOH] for 3p). Of the other 2 cases with predominantly characteristic CRCC morphology, 1 tumor did not reveal any VHL mutation, VHL promoter methylation, or LOH for 3p, and both chromosomes 7 and 17 were disomic, whereas the other tumor displayed polysomy for chromosomes 7 and 17 and no VHL mutation, VHL promoter methylation, or LOH for 3p. One tumor was composed primarily (95%) of distinctly RAT/CCPRCC-like morphology, and this tumor harbored a VHL mutation and displayed polysomy for chromosomes 7 and 17. Of the 5 cases with both histomorphologic features and molecular genetic findings of CRCC, we detected significant immunoreactivity for α-methylacyl-CoA racemase in 2 cases and strong diffuse immunopositivity for cytokeratin 7 in 3 cases. Despite the combination of positivity for α-methylacyl-CoA racemase and cytokeratin 7 in 2 cases, there was nothing to suggest of the possibility of a conventional papillary renal cell carcinoma with a predominance of clear cells.

    Objective: To investigate the relationship between the expression of Fas and Fas ligand (FasL) and its biological behavior in human cervix carcinoma. Methods: Immunohistochemisty technique was used to detect the expression of Fas and FasL in 47 cases of cervical carcinoma, 16 cases of cervical interaepithelial neoplasia, 10 cases of chronic cervicitis and 10cases of normal cervix. TUNEL technique was used to observe the apoptic cells in 47 cases of cervical carcinoma. Retrospective study was carried out to find the relationship between the expression of Fas and FasL and cell apoptosis, clinical stage, pathological classification, lymph node metastasis, prognosis and age. Results: The expression of Fas and FasL was significantly different in different cervix (P < 0.01 ), and also related to the degree of differentiation, lymph node metastasis and prognosis (P < 0.05).But had no relation with clinical stage or age (P > 0.05); Cervix carcinoma cells apoptosis in different pathological classification appeared negative relation (Rs=-0.35, P < 0.05). Cervix carcinoma cell apoptosis was significantly higher in Fas-positive and FasLpositive than that in Fas-negative and FasL-negative (P < 0.05). By retrospective investigation, Fas-negative and FasL-positive were related to poor prognoses of the patients with cervical carcinoma (P < 0.05). Conclusion: The development of apoptosis in cervix carcinoma has a promoting regulation function in Fas and FasL expression. Gene treatment can alter apoptosis abnormality,thus induce apoptosis in cancerous cell expressing Fas and FasL. Fas or FasL may be taken as a marker in the prognostic characterization.

    Breast metastases from extramammary neoplasms are very rare. We presented a 66 year-old female with metastasis of small cell lung carcinoma to the breast. She presented with consolidation over the left upper lobe of her lung undetermined after endobronchial or video-assisted thoracoscopic surgery (VATS) biopsy, and this was treated effectively after antibiotic therapy at initial stage. The left breast lumps were noted 4 months later, and she underwent a modified radical mastectomy under the impression of primary breast carcinoma. However, the subsequent chest imaging revealed re-growing mass over the left mediastinum and hilum, and cells with the same morphological and staining features were found from specimens of transbronchial brushing and biopsy. An accurate diagnosis to distinguish a primary breast carcinoma from metastatic one is very important because the therapeutic planning and the outcome between them are different.

  13. Is interferon-α and retinoic acid combination along with radiation superior to chemo-radiation in the treatment of advanced carcinoma of cervix?

    Directory of Open Access Journals (Sweden)

    Basu Partha

    2006-01-01

    Full Text Available Locally advanced cervical cancers comprise a large majority of the gynecologic cancers in India and other developing countries. Concurrent chemo-radiation has improved the survival of high risk stage I and stage II cervical cancers. There is no evidence that the same survival benefit has been achieved with chemo-radiation in stage III and stage IV disease. Interferon-a and Retinoic acid have synergistic anti-proliferative activity. In combination with radiation, they substantially enhance the sensitivity of the squamous carcinoma cells to radiation. Based on these observations from the in vitro studies, a few clinical trials have evaluated the combination of interferon-a and Retinoic acid, concomitant with radiation, to treat cervical cancers. The results from these early trials were encouraging and the combination had minimal toxicities. However, till date, no phase III randomized controlled trial has been done to evaluate this therapeutic modality.

    2016-06-01

    The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

    The traditional view that adult human liver tumors, mainly hepatocellular carcinoma (HCC), arise from mature cell types has been challenged in recent dec-ades. The results of several studies suggest that HCC can be derived from liver stem cells. There are four levels of cells in the liver stem cell lineage: hepatocytes, hepatic stem cells/oval cells, bone marrow stem cells and hepato-pancreas stem cells. However, whether HCC is resulted from the differentiation block of stem cells and, moreover, which liver stem cell lineage is the source cell of hepatocarcinogenesis remain controversial. In this review, we focus on the current status of liver stem cell research and their roles in carcinogenesis of HCC, in order to explore new approaches for stem cell therapy of HCC.

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

    Full Text Available The basal cell carcinoma is the most common skin tumour especially affecting the white individuals worldwide. The exact incidence of basal cell carcinoma is not known from India but non melanoma skin cancers comprises about 1-2% of cutaneous tumour in India. The most common skin tumour is squamous cell carcinoma in albinism and the incidence of basal cell carcinoma is less. Hereby, we report a peculiar case of basal cell carcinoma in albinism to highlights the importance of early recognition and diagnosis of suspected lesions by performing histopathological examination in unusual circumstances.

    Full Text Available Abstract Background Merkel cell polyomavirus (MCPyV was identified originally in Merkel cell carcinoma (MCC, a rare form of human skin neuroendocrine carcinoma. Evidence of MCPyV existence in other forms of malignancy such as cutaneous squamous cell carcinomas (SCCs is growing. Cervical cancers became the focus of our interest in searching for potentially MCPyV-related tumors because: (i the major histological type of cervical cancer is the SCC; (ii the uterine cervix is a common site of neuroendocrine carcinomas histologically similar to MCCs; and (iii MCPyV might be transmitted during sexual interaction as demonstrated for human papillomavirus (HPV. In this study, we aimed to clarify the possible presence of MCPyV in cervical SCCs from Japanese patients. Cervical adenocarcinomas (ACs were also studied. Results Formalin-fixed paraffin-embedded tissue samples from 48 cervical SCCs and 16 cervical ACs were examined for the presence of the MCPyV genome by polymerase chain reaction (PCR and sequencing analyses. PCR analysis revealed that 9/48 cervical SCCs (19% and 4/16 cervical ACs (25% were positive for MCPyV DNA. MCPyV-specific PCR products were sequenced to compare them with reference sequences. The nucleotide sequences in the MCPyV large T (LT-sequenced region were the same among MCPyV-positive cervical SCCs and AC. Conversely, in the MCPyV viral protein 1 (VP1-sequenced region, two cervical SCCs and three cervical ACs showed several nucleotide substitutions, of which three caused amino acid substitutions. These sequencing results suggested that three MCPyV variants of the VP1 were identified in our cases. Immunohistochemistry showed that the LT antigen was expressed in tumor cells in MCPyV-positive samples. Genotyping of human HPV in the MCPyV-positive samples revealed that infected HPVs were HPV types 16, 31 and 58 for SCCs and HPV types 16 and 18 for ACs. Conclusions This study provides the first observation that MCPyV coexists in a subset

    Purpose: To evaluate the treatment results of patients (pts) with Figo stage IB2, IIA, IIB cervical carcinoma (C.C.) treated with preoperative radio chemotherapy, followed by extended radical hysterectomy. Patients and methods: Retrospective study of 148 women treated to the Curie Institute for operable Figo Stage IB2 to IIB, biopsy proved C.C.. Among them, 70 pts, median age 46 years, were treated using the same regimen associating primary radio cis-platinum based chemotherapy,intracavitary LDR brachytherapy, followed by extended radical hysterectomy. Kaplan-Meier estimates were used to draw survival curves. Comparisons of survival distribution were assessed by the log-rank test. Results: Complete histological local-regional response was obtained in 56% of the pts (n = 39). Residual macroscopic or microscopic disease in the cervix was observed in 28 pts (40%). All but one had in situ microscopic residual C.C.. Lateral residual disease in the parametria was also present in nine pts, all with residual C.C.. Pelvic lymph nodes were free from microscopic disease in 56 pts (80%). Eight of 55 (11%) radiological N0 patients had microscopic nodal involvement, as compared to 6/15 (40%) radiological N1 (p = 0.03). Seventeen pts (25%) had residual cervix disease but negative nodes. After median follow-up of 40 months (range, 8-141), 38/70 patients (54.1%) are still alive and free of disease, six (8.6%) alive with disease, and 11 (15.8%) patients were lost for follow-up but free of disease. Conclusion: The treatment of locally advanced C.C. needs a new multidisciplinary diagnostic and treatment approach using new therapeutic arms to improve the survival and treatment tolerance among women presenting this disease.

    Conclusions: A women with a preinvasive lesion of cancer cervix can be asymptomatic. This requires a task force for mass screening of all women in the community. Community health workers begin screening of all women from 21 years onwards with Pap smear and colposcopy. The trained heath workers can be used for downstaging of cancer cervix leading to a dramatic reduction in the incidence of invasive carcinoma. Even when a colposcopist detects the invasive carcinoma, it is so early that an 85-100% five-year survival rate can be achieved. [Int J Reprod Contracept Obstet Gynecol 2016; 5(8.000: 2515-2518

    Because primary pure squamous cell carcinoma (SCC) of the endometrium is very rare and its frequency is unknown, the author reviewed 142 archival hysterectomy specimens of endometrial cancers. As the results, one case of primary pure SCC was found. Thus, the frequency of SCC of the endometrium was 0.7% of all endometrial malignancies in our institution. The patient was a 72-year-old woman presenting with uterine bleeding. Uterine curettage biopsy and uterine discharge cytology revealed SCC. No malignancy was seen in cervical biopsy. Radical hysterectomy, bilateral salpingo-oophorectomy, omentectomy and lymph node dissection were performed. The endometrial carcinoma was an infiltrative polypoid tumor composed of non-keratinizing SCC with stratification and intercellular bridges. No adenocarcinoma element was recognized. The SCC cells were immunohistochemically positive for p53 protein and showed high Ki-67 antigen (labeling, 70%). The SCC was found to invade into the deeper third of the myometrium. No tumor cells were seen in other sites including the cervix, ovaries, omentum, and lymph nodes. The patients was FIGO stage IC (pT1C, N0, M0), and was treated with radiation and adjuvant chemotherapy. The patient is now alive without recurrence and metastasis 15 months after the operation.

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

    analyzed by histopathology (hematoxylin and eosin and immunohistochemically evaluated using monoclonal antibodies for p53 and Ki-67. Data were analyzed statistically by the chi2 test to evaluate eventual differences between the groups. RESULTS: the age of the patients ranged from 27 to 73 years (48.7±10.4 years. Clinical stage (FIGO was IB1 in 27 cases (75% and IB2 in 9 cases (25%. A positive tumoral expression of the p53 protein was found in half of the cases. In relation to the Ki-67 expression, a high cell proliferation index was shown in 73.3% of the cases. There was no association between tumoral p53 and Ki-67 expression with age (p=0.091 and 0.900, clinical stage (p=0.054 and 0.667, histological classification (p=0.674 and 0.674, grade of differentiation (p=0.070 and 0.282, presence of lymphatic vascular space invasion (p=0.248 and 0.667, parametrial involvement (p=0.729 and 0.763 and pelvic lymph node metastasis (p=0.729 and 0.636, respectively. CONCLUSIONS: tumoral expression of p53 and Ki-67 was not associated with the clinicopathological features in patients with stage IB carcinoma of the cervix.

    Full Text Available Abstract Background Calcineurin (CaN is an important serine-threonine phosphatase (PP2B, which plays a crucial role in calcium-calmodulin mediated signal transduction events. Calcineurin has been implicated in pathogenesis of various diseases cardiac hypertrophy, diabetic neuropathy and Alzheimer's, however its role in neoplasia remains unclear. Results In view of this we evaluated the calcineurin activity in serum and biopsy samples collected from women diagnosed with invasive squamous cell carcinoma of cervix. A significant reduction was observed in the calcineurin activity in cancer cervix patients compared to the control group. However the calcineurin activity remained unaltered in the cervical scrapes obtained from patients diagnosed with low-grade squamous intra epithelial lesions (LSIL. Interestingly the downregulation of calcineurin activity in squamous cell carcinomas was not accompanied by any significant change in DNA-binding affinity of the transcriptional factor NFAT (Nuclear Factor of Activated T-cells. All the squamous cell carcinoma samples used in the present study were positive for high-risk human papillomavirus (HPV types. Conclusion The present study demonstrates the downregulation of calcineurin activity in squamous cell carcinoma of cervix with high risk HPV infection. We conclude that perturbations in calcineurin-mediated pathway may be involved in development of cervical neoplasia.

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

    High-risk human papillomavirus (hrHPV) is an etiologic agent in squamous cell carcinoma (SqCC) arising in the oropharynx and cervix, and a proven prognostic factor in oropharyngeal SqCC. Many studies have found HPV in non-small cell lung carcinoma (NSCLC). Recent studies advocate the detection of messenger RNA transcripts of E6/E7 as more reliable evidence of transcriptively active HPV in tumor cells. The clinical significance of finding HPV remains unclear in NSCLC. This study sought to determine the prevalence of biologically active HPV infection in NSCLC comparing different methodologies. Surgical pathology material from resected primary lung adenocarcinoma (ADC; n=100) and SqCC (n=96) were retrieved to construct tissue microarrays. In situ hybridization (ISH) for hrHPV DNA (DNA-ISH), hrHPV E6/E7 RNA (RNA-ISH), and p16 immunohistochemistry were performed. Cases of oropharyngeal SqCC with known HPV infection were used as positive controls. Expression of p16 was scored as positive if at least 70% of tumor cells showed diffuse and strong nuclear and cytoplasmic staining. Punctate nuclear hybridization signals by DNA-ISH in the malignant cells defined an HPV-positive carcinoma. Of the 196 patients (range, 33-87 years; 108 men), p16 was positive in 19 ADCs and 9 SqCCs, but HPV DNA-ISH and RNA-ISH were negative in all cases. Our study did not detect HPV infection by DNA-ISH or RNA-ISH in any cases of primary NSCLC despite positive p16 expression in a portion of ADC and SqCC. p16 should therefore not be used as a surrogate marker for HPV infection in NSCLC.

    Basaloid squamous cell carcinoma of the esophagus is a rare variant of squamous cell carcinoma. We reviewed 878 cases of esophageal squamous cell carcinoma and detected 22 cases (3%) of basaloid squamous cell carcinoma. These tumors and stage-matched paired conventional squamous cell carcinomas were investigated for clinicopathologic features and immunoreactivity of cytokeratin subtypes, p53, B-cell lymphoma 2 (bcl-2), β-catenin, and epidermal growth factor receptor. Molecular aberrations in p53, CTNNB1 (the gene encoding β-catenin), and epidermal growth factor receptor (EGFR) were also determined. Patients with basaloid squamous cell carcinomas demonstrated a 5-year survival rate of 42%, significantly worse than those with well-differentiated squamous cell carcinoma (Pcarcinomas, the basaloid squamous cell carcinomas were less immunoreactive for cytokeratin 14, cytokeratin 903, and membranous β-catenin (Pcarcinomas, low-level expression of cytokeratin 14/cytokeratin 903 and mutations of p53 and EGFR had a significant influence on worse survival (Pcarcinoma, a neoplasm with particularly aggressive biologic behavior, should be differentiated from conventional squamous cell carcinomas. In this context, immunohistochemical assessment of several markers might provide a useful adjunct diagnostic tool. Aberrations of p53 and epidermal growth factor receptor genes are possibly involved in progression of esophageal basaloid squamous cell carcinoma.

    The presence of pleomorphic tumor giant cells in thyroid carcinomas of follicular cell origin is always worrisome for the pathologist as they first of all refer to anaplastic carcinoma, one of the most aggressive human malignancies. However, non-anaplastic pleomorphic giant cells are well described in other thyroid diseases, most often benign. In this paper, we describe four cases of papillary thyroid carcinoma displaying pleomorphic tumor giant cells with features that differ from those of anaplastic carcinoma. Pleomorphic giant cells were admixed with the underlying thyroid carcinoma and constituted from 5% to 25% of the tumor. Cytologically, they had an abundant eosinophilic cytoplasm with large and irregular nuclei. Compared to pleomorphic giant cells of anaplastic carcinoma, they reproduced the growth pattern of the underlying carcinoma, had a low mitotic index without necrosis or inflammation, and were reactive with thyroglobulin and thyroid-specific transcription factor-1 and strongly and diffusely positive for cytokeratin AE1/AE3. After 16-84 months of follow-up, patients are relapse-free and still alive. These cases show that pleomorphic tumor giant cells arising in papillary thyroid carcinomas do not always represent dedifferentiation and progression to anaplastic carcinoma. Distinction among these processes is critical as their treatment and prognosis are very different.

This study evaluates birch bark extracts for the active principles composition. Results New improved extraction methods were applied on the bark of Betula pendula in order to reach the maximum content in active principles. Extracts were analyzed by HPLC-MS, Raman, SERS and 13C NMR spectroscopy which revealed a very high yield of betulin (over 90%. Growth inhibiting effects were measured in vitro on four malignant human cell lines: A431 (skin epidermoid carcinoma, A2780 (ovarian carcinoma, HeLa (cervix adenocarcinoma and MCF7 (breast adenocarcinoma, by means of MTT assay. All of the prepared bark extracts exerted a pronounced antiproliferative effect against human cancer cell lines. In vivo studies involved the anti-inflammatory effect of birch extracts on TPA-induced model of inflammation in mice. Conclusions The research revealed the efficacy of the extraction procedures as well as the antiproliferative and anti-inflammatory effects of birch extracts.

We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

  8. Cacospongionolide and scalaradial, two marine sesterterpenoids as potent apoptosis-inducing factors in human carcinoma cell lines.

    Directory of Open Access Journals (Sweden)

    Daniela De Stefano

    Full Text Available Apoptosis, a form of programmed cell death, is a critical defence mechanism against the formation and progression of cancer and acts by eliminating potentially deleterious cells without causing such adverse effects, as inflammatory response and ensuing scar formation. Therefore, targeting apoptotic pathways becomes an intriguing strategy for the development of chemotherapeutic agents. In last decades, marine natural products, such as sesterterpenoids, have played an important role in the discovery and development of new drugs. Interestingly, many of these compounds have a strong potential as anticancer drugs by inhibiting cell proliferation and/or inducing cell death. In the present study, we investigated the effects of scalaradial and cacospongionolide, two sesterterpenoids from Cacospongia scalaris and Fasciospongia cavernosa marine sponges, on the apoptotic signalling pathway in three different human tumoral cells. Results were obtained by using DNA fragmentation, comet and viability assays, quantification of the mitochondrial transmembrane potential and Western blot. The T47D (human breast carcinoma, A431 (human epidermoid carcinoma, HeLa (human cervix carcinoma and HCT116 (human colon carcinoma cells were incubated for 24 h with scalaradial or cacospongionolide. Treatment of T47D cells with scalaradial or cacospongionolide for 24 h brought about a significant increase in DNA migration as well as fragmentation. Moreover, incubation of HCT116 and HeLa cells with scalaradial or cacospongionolide for 24 h caused an increased expression of pro-apoptotic proteins. Furthermore, scalaradial or cacospongionolide, added to HCT116 and HeLa cells overnight, induced a significant and concentration-dependent loss of mitochondrial transmembrane potential, an early apoptosis signalling event. These effects paralleled with those achieved with p50 and p65, NF-κB subunits, nuclear level. In conclusion, scalaradial and cacospongionolide, by determining human

    Full Text Available Malignant sinonasal carcinomas are a rare entity comprising less than 1% of all cancers and around 3% of all head and neck malignancies seen in humans. Among these 15-20% are transitional cell carcinoma also known as non keratinizing carcinoma of sinonasal tract. We are reporting the case of a 45 years female with history of nasal obstruction and epistaxis. A contrast enhanced computed tomography (CECT was done which showed mucosal thickening in the right nasal cavity. Endoscopy assisted biopsy was taken which revealed non keratinizing carcinoma (transitional type. Very few reported cases of this type of malignancy was found. A possible reason could be multiple synonyms like cylindrical cell carcinoma, Schneiderian carcinoma and transitional cell carcinoma.

    Anal sac squamous cell carcinoma is rare in dogs. Five cases have been previously reported, treatment of which involved surgery alone. This report describes three further cases of canine anal sac squamous cell carcinoma which underwent medical (meloxicam) management alone, resulting in survival of up to seven months. No metastases were identified. Squamous cell carcinoma, although extremely uncommon, should be considered as a possible differential diagnosis when a dog is presented for investigation of an anal sac mass.

    Squamous cell carcinoma arising from balanitis xerotica obliterans is rarely reported. We describe an 83-year-old man in whom metastatic penile squamous cell carcinoma developed after 18 years of observation for balanitis xerotica obliterans. It is important to recognize the possibility of this uncommon complication of balanitis xerotica obliterans, because survival of patients with squamous cell carcinoma depends on early diagnosis and treatment.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different cancer cell lines--human cervix adenocarcinoma HeLa, human breast adenocarcinoma MDA-MB-361, and human breast carcinoma MDA-MB-453--and normal human peripheral blood mononuclear cells (PBMCs). Qualitative and quantitative compositions of wine polyphenolic extracts obtained by fractional vacuum distillation of corresponding wines were determined using spectrophotometric methods and high-performance liquid chromatography with diode array detection and liquid chromatography with electrospray ionization-time of flight mass spectrometry analysis. It was demonstrated that wine polyphenolic extracts and resveratrol exerted higher cytotoxic activity against HeLa and MDA-MB-453 cells in comparison to MDA-MB-361 cells and unstimulated and stimulated PBMCs. Furthermore, white wine polyphenolic extract exhibited a significantly higher antiproliferative action on cancer cell lines than red wine extract. The presence of condensed or fragmented nuclei in HeLa cells, pretreated with extract of white wine and stained with a mixture of acridine orange and ethidium bromide, pointed to the morphological signs of apoptosis. In addition, HeLa cells in late stages of apoptosis or secondary necrosis were also observed. Results from our study suggest that polyphenolic extracts from red and white wine may have anticarcinogenic potential.

  15. Histopathological transformation to small-cell lung carcinoma in non-small cell lung carcinoma tumors.

    2016-08-01

    Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors. By definition, SCLC is a high-grade tumor with specific histological and genetic characteristics. In the majority of cases, a good-quality hematoxylin and eosin (H&E) stain is enough to establish a diagnosis. Immunohistochemistry (IHC) is used to confirm the diagnosis and exclude other neoplasia such as sarcomatoid carcinomas, large-cell carcinoma, basaloid squamous-cell carcinoma, chronic inflammation, malignant melanoma, metastatic carcinoma, sarcoma, and lymphoma. A loss of the tumor-suppressor protein retinoblastoma 1 (RB1) is found in 100% of human SCLC tumors; therefore, it has an essential role in tumorigenesis and tumor development. Other genetic pathways probably involved in the histopathological transformation include neurogenic locus notch homolog (NOTCH) and achaete-scute homolog 1 (ASCL1). Histological transformation to SCLC can be suspected in NSCLC patients who clinically deteriorate during active treatment. Biopsy of any new lesion in this clinical setting is highly recommended to rule out a SCLC transformation. New studies are trying to assess this histological transformation by noninvasive measures such as measuring the concentration of serum neuron-specific enolase.

    2013-05-01

    Full Text Available Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma. In patients with mucinous adenocarcinoma in the abdominal cavity, caution should be exercised in interpreting the possible primary site of the tumor on the basis of the immunohistochemical profiles. The presence of human papillomavirus (HPV DNA is assessed to determine whether the ovarian neoplasms were metastases or primary independent neoplasm. Approximately 90% of endocervical adenocarcinomas are related to high-risk human papillomavirus (hr-HPV with the remainder being unrelated to HPV. Both types metastasize to the ovaries very infrequently. Ovarian endocervical-type (mullerian mucinous tumors and tumors composed of a mixture of endocervical-type mucinous, serous endometrioid, squamous, and indifferent cells with abundant eosinophilic cytoplasm reported to date have been primarily limited to borderline and micro invasive types. We report a-36-yr old woman with adenocarcinomas of uterine cervix who also had ovarian mucinous borderline tumor.Case presentation: The patient presented with abnormal uterine bleeding and lower abdominal pain. She had a history of uterine cervix polyps. Pelvic ultrasound showed a right adnexal mass and a large cervical size. Histological diagnosis in uterine cervix biopsy revealed adenocarcinoma of cervix. Radical hysterectomy type III with bilateral salpingo-oophorectomy was performed. Histological finding in adnexal mass revealed borderline mucinous tissue of ovarian tumor. Testing for HPV DNA in the tumoral tissue was negative. This confirms that the ovarian tumor is not metastatic from endocervical adenocarcinoma. Conclusion: We conclude that in a patient with

    Full Text Available Merkel cell carcinoma is a rare, aggressive, malignant cutaneous tumor. It usually appears on the sun-exposed areas such as the head and neck in the elderly. A 72-year-old female patient was admitted to our clinic with the complaints of a big mass on her face. She described that the mass on her left cheek rapidly grew in three months. Her family and own medical history was unremarkable for skin cancers. On physical examination, there were no pathological findings except for a palpable submandibular lymphadenopathy. Dermatological examination revealed a giant tumoral lesion 9x9 cm in diameter, containing crusted and ulcerated areas on her left cheek. Histopathological examination of the specimen obtained from the lesion showed a neoplastic infiltration consisting small, atypic cells with big, round, hyperchromatic nucleus, narrow cytoplasms, and prominent nucleoulus in some areas, showing high mitotic activity. The neoplasm, which had apoptotic bodies and necrobiosis, also invaded the full thickness of the skin, and the epidermis was very thin. In immunochemistry, CK20 was strongly positive, S100 was focally positive, and EMA was positive, while synaptophysin, chromogranin, vimentin, CD3, CD20, as well as CD45, and CD99 were all negative. Based on these findings, the patient was diagnosed as having Merkel cell carcinoma. On the systemic screening for metastases, nodular lesions in the lungs compatible with metastases were detected on computed tomography. By the consultations with plastic and reconstructive surgeons and oncologists, she was accepted as inoperable and etoposide monotherapy was administered. In this report, we aimed to underline the importance of early diagnosis while presenting a case of giant Merkel cell carcinoma which shows an aggressive progression with lung metastases.

    Full Text Available Abstract Background Hürthle cell carcinoma is a variant of follicular cell carcinoma of thyroid. It may present as a low-grade tumour or as a more aggressive type. Prognosis depends upon the age of the patient, tumour size, extent of invasion and initial nodal or distant metastasis. Patient and methods The case of Hürthle cell carcinoma is reported in a 79-year-old man who presented with a rapidly increasing lump on the left side of his neck, having had a right hemithyroidectomy for colloid goitre 24-years-ago. Fine needle aspiration cytology confirmed the presence of Hürthle cells, raising the possibility of a Hürthle cell neoplasm. The patient underwent staging and surgery. Histology showed Hürthle cell carcinoma and the patient underwent adjuvant therapy. The literature on Hürthle cell neoplasms is reviewed. Conclusions Fine needle aspiration cytology may recognise Hürthle cell lesion but final diagnosis of carcinoma depends upon histological confirmation of vascular or capsular invasion. Staging and surgery in Hürthle cell carcinoma are similar to follicular carcinoma of thyroid with favourable outcome despite the controversy regarding the histological classification and adjuvant therapy. Elderly patients with Hürthle cell carcinoma need to be made aware of their poorer prognosis and should be offered more radical treatment.

    Objective:To explore the expression of DNA polymerase iota in transitional cell carcinoma cells and tissues; Methods: RT-PCR was applie to detect the expression of polymerase iota in BIU87 and T24 cells, then the expression of polymerase iota was also detected in the same way in transitional cell carcinoma which was derived from clinical bladder carcinoma and renal pelvic carcinoma. Results: The expression of Polt was low in bladder normal membrana mucosa but significantly elevated in transitional cell carcinoma cells. Compared with the expression of polymerase iota in bladder normal mucous membranes, the expression of polymerase iota was significantly increased in transitional cell carcinoma tissue (P<0.01)and associated with the grade of transitional cell carcinoma. Conclusion: The significantly increased expression of polymerase iota may be associated with the generation and development of transitional cell carcinoma, even with its high heterogenicity.

    Objective To discuss treatment options for tonsillar squamous cell carcinoma.Methods A total of 108 patients with biopsy-proven tonsillar squamous cell carcinoma, treated between 1984 and 2000, were reviewed, including 82 men and 26 women, with ages ranging from 19 to 70 years. Treatments consisted of either radiotherapy and surgery reserved as salvage treatment (Salvage Surgery, 83 patients), or planned surgery with preoperative radiation (Planned Surgery, 25 patients). Radiotherapy was delivered primarily in a dosage of 60-70 Gy for Salvage Surgery patients and 40-50 Gy for Planned Surgery patients. Both salvage and planned surgeries were radical, with resection of the lateral oropharyngeal wall, segmental resection of the mandible and neck dissection. The pectoralis major myocutaneous flaps were used to repair surgical defects. Results The percentages of radical surgery used in the Salvage Surgery and Planned Surgery groups were 24.1% (20/83) and 88.0% (22/25), respectively (P=0.000). The local recurrence rates were 28.9% (24/83) and 20.0% (5/25) in the Salvage Surgery and Planned Surgery groups, respectively (P= 0.378). The neck recurrence rates were 9.6% (8/83) and 8.0% (2/25) in the Salvage Surgery and Planned Surgery groups respeatively (P= 0.804). The 5-year survival rates were 59.3% and 55.3% in the Salvage Surgery and Planned Surgery groups, respeatively (P= 0.7056).Conclusions Although the two treatments had a similar survival rate, Salvage Surgery avoided 60% commando operations compared with the Planned Surgery group, which benefits to recovery of oral functions. Primary radiotherapy is recommended as the treatment of choice for tonsillar squamous cell carcinoma. After radical radiotherapy, salvage surgery should be undertaken in the case of tumor remnants or recurrences.

    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC. Keywords: thyroid cancer, thyroid nodule, follicular cell carcinoma, Hurthle cell lesion, minimally invasive HCC

    Lung large cell neuroendocrine carcinoma (L-LCNEC) is a rare, aggressive, and difficult-to-treat tumor. It is classified as a neuroendocrine subtype of large cell lung carcinoma (LCLC) belonging to the non-small cell lung cancer (NSCLC) group, but it is also included in the neuroendocrine tumor (NET) group. Most of the available data related to its treatment derive from retrospective analyses or small case series. For patients with L-LCNEC, prognosis is generally very poor. In early stages (I-II-III), surgery is recommended but does not seem to be sufficient. Platinum-based adjuvant chemotherapy may be useful while the role of neoadjuvant chemotherapy is still not well defined. In patients with advanced L-LCNEC, the chemotherapy regimens used in SCLC still remain the standard of treatment, but results are not satisfactory. Due to their peculiar clinical and biological features and the lack of literature data, there is an emerging need for a consensus on the best treatment strategy for L-LCNEC and for the identification of new therapeutic options. In this review, we will discuss the key aspects of L-LCNEC management with the aim to clarify the most controversial issues.

    Full Text Available Renal cell carcinoma (RCC is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy has been the “gold standard” for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.e. stage 1A or 1B.  This has provided an impetus for expanding the nephron sparing options and especially, percutaneous ablative techniques.  Percutaneous ablation for RCC is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection or when there is a need to preserve renal function due to comorbid conditions, multiple renal cell carcinomas, and/or heritable renal cancer syndromes. During the last few years, percutaneous cryoablation has been gaining acceptance as a curative treatment option for small renal cancers. Clinical studies to date indicate that cryoablation is a safe and effective therapeutic method with acceptable short and long term outcomes and with a low risk, in the appropriate setting.  In addition it seems to offer some advantages over radio frequency ablation (RFA and other thermal ablation techniques for renal masses.

    Invasion into the matrix is one of hallmarks of malignant diseases and is the first step for tumor metastasis. Thus, analysis of the molecular mechanisms of invasion is essential to overcome tumor cell invasion. In the present study, we screened for colon carcinoma-specific genes using a cDNA microarray database of colon carcinoma tissues and normal colon tissues, and we found that fermitin family member-1 (FERMT1) is overexpressed in colon carcinoma cells. FRRMT1, FERMT2 and FERMT3 expression was investigated in colon carcinoma cells. Reverse transcription polymerase chain reaction (RT-PCR) analysis revealed that only FERMT1 had cancer cell-specific expression. Protein expression of FERMT1 was confirmed by western blotting and immunohistochemical staining. To address the molecular functions of FERMT genes in colon carcinoma cells, we established FERMT1-, FERMT2- and FERMT3-overexpressing colon carcinoma cells. FERMT1-overexpressing cells exhibited greater invasive ability than did FERMT2- and FERMT3-overexpressing cells. On the other hand, FERMT1-, FERMT2- and FERMT3-overexpressing cells exhibited enhancement of cell growth. Taken together, the results of this study indicate that FERMT1 is expressed specifically in colon carcinoma cells, and has roles in matrix invasion and cell growth. These findings indicate that FERMT1 is a potential molecular target for cancer therapy.

    Hürthle cell carcinoma is a rare variant of differentiated thyroid cancer that occasionally forms distant metastases. However, even in the presence of metastases, patients with Hürthle cell carcinoma have a relatively good prognosis. There are few reports of Hürthle cell carcinoma metastases to the vertebral column, and none describing aggressive resection of spinal metastases. Here, we report a 68-year-old woman with a solitary metastasis of Hürthle cell carcinoma to the T1 vertebral body causing severe kyphotic deformity, myelopathy, and pain. The patient was treated with aggressive excisional decompression of the spinal cord and T1 vertebral body resection from an entirely posterior approach. Reconstruction and stabilization of the anterior spine was accomplished with a transforaminal lumbar interbody fusion allograft spacer and posterior instrumentation. We discuss aspects of the diagnosis, management, patient selection, and surgical treatment of metastatic Hürthle cell carcinoma in reference to the literature.

    Full Text Available Reena Kabaria, Zachary Klaassen, Martha K Terris Department of Surgery, Section of Urology, Augusta University, Augusta, GA, USA Abstract: This review provides an overview of the incidence of renal cell carcinoma (RCC and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses. The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Hepatocyte nuclear factor 1-beta (HNF1β) has recently emerged as a relatively sensitive and specific marker for ovarian clear cell carcinoma. The purpose of this study is to assess the diagnostic utility of this marker for endometrial clear cell carcinoma. Immunohistochemical analysis was performed on 75 endometrial tissues using a goat polyclonal antibody raised against a peptide mapping at the C-terminus of human HNF1β protein. The 75 cases included 15 clear cell carcinomas, 20 endometrioid carcinomas, 15 endometrial serous carcinomas/uterine papillary serous carcinomas, 20 cases of normal endometrium, 2 cases of clear cell metaplasia, and 3 cases of Arias Stella reaction. Staining interpretations were based on a semiquantitative scoring system, a 0 to 12+ continuous numerical scale that was derived by multiplying the extent of staining (0 to 4+ scale) by the intensity of staining (0 to 3+ scale) for each case. HNF1β expression was found to be present in a wide spectrum of tissues. Twenty-seven (54%) of the 50 carcinomas displayed at least focal nuclear HNF1β expression, including 11 (73%) of 15, 9 (60%) of 15, and 7 (35%) of 20 clear cell, serous, and endometrioid carcinomas, respectively. The average nuclear staining scores for clear cell carcinomas, endometrioid carcinomas, and serous carcinomas were 5.2, 1.4, and 4.1, respectively. Clear cell carcinomas and endometrioid carcinomas displayed statistically significant differences regarding their nuclear staining scores (P = 0.0027), but clear cell carcinomas and endometrial serous carcinomas did not (P = 0.45). The calculated sensitivity of any nuclear HNF1β expression in classifying a carcinoma as being of the clear cell histotype was 73%, whereas the specificity was 54%. Nineteen of 20 normal endometrium samples displayed at least focal nuclear expression of HNF1β, and this expression was often diffuse. The 5 cases of benign histologic mimics of clear cell carcinomas (Arias Stella reaction and clear

    A 55-year-old man with esophageal carcinoma received endoscopic submucosal dissection (ESD) in en-bloc resection. Histopathological examination revealed an admixture of squamous cell carcinoma (SCC) and endocrine cell carcinoma (ECC) with invasion of the deep submucosa. Immunohistochemically, CD 56 and chromogranin A were positive for ECC. Small-cell, medium-cell, and large-cell type ECC were partly surrounded with SCC and partly formed the duct, presenting various patterns. After ESD, he received chemotherapy including CPT-11 plus Cisplatin. He is alive and in good condition today, 55 months after ESD, with no evidence of recurrence.

    A 4-year and 2-month-old male capybara (Hydrochoerus hydrochaeris) was diagnosed with squamous cell carcinoma on the buttocks after chronic recurrent dermatosis. The capybara was euthanized, examined by computed tomography and necropsied; the tumor was examined histologically. Computed tomography showed a dense soft tissue mass with indistinct borders at the buttocks. Histological examination of the tumor revealed islands of invasive squamous epithelial tumor cells with a severe desmoplastic reaction. Based on the pathological findings, the mass was diagnosed as a squamous cell carcinoma. This is the first study to report squamous cell carcinoma in a capybara.

    Spindle cell carcinoma is a malignancy of epithelial origin often mimicking its mesenchymal counterpart thus posing a diagnostic challenge. It is a rare biphasic malignant tumour mostly encountered in the upper aerodigestive tract. The chief differential diagnoses of spindle cell carcinoma are true superficial sarcomas and they especially need to be differentiated from fibrosarcoma. This presentation reports a spindle cell carcinoma of the gingiva and highlights the difficulties encountered in the diagnosis. It also emphasizes the importance of accurate and thorough diagnosis of malignant spindle cell lesions to determine the appropriate therapeutic modality.

    Full Text Available 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.

    Most Merkel cell carcinomas display pure neuroendocrine differentiation (pure Merkel cell carcinoma), whereas a minority show combined neuroendocrine and nonneuroendocrine elements (combined Merkel cell carcinoma). Recent identification of Merkel cell polyomavirus DNA and Merkel cell polyomavirus large T antigen expression in a proportion of Merkel cell carcinomas has suggested viral-induced oncogenesis. To date, Merkel cell polyomavirus immunohistochemistry has shown an absence of viral large T antigen expression in combined Merkel cell carcinoma as well as select non-Merkel cell carcinoma cutaneous lesions and visceral neuroendocrine tumors. In our series, we aimed to further characterize the frequency and pattern of Merkel cell polyomavirus large T antigen expression by CM2B4 immunohistochemistry in primary and metastatic Merkel cell carcinoma (pure Merkel cell carcinoma and combined Merkel cell carcinoma) and various non-Merkel cell carcinoma lesions from patients with Merkel cell carcinoma, patients without Merkel cell carcinoma, and individuals with altered immune function. Merkel cell polyomavirus large T antigen was detected in 17 (63%) of 27 pure Merkel cell carcinomas and absent in all 15 (0%) combined Merkel cell carcinomas. Furthermore, complete concordance (100%) of Merkel cell polyomavirus large T antigen expression was observed in 10 cases of primary Merkel cell carcinoma and subsequent tumor metastases. We also evaluated 70 non-Merkel cell carcinoma lesions including 15 cases each of pulmonary and gastrointestinal neuroendocrine tumors. All 70 non-Merkel cell carcinoma lesions were negative for Merkel cell polyomavirus by CM2B4 immunohistochemistry, irrespective of any known Merkel cell carcinoma diagnosis and immune status. In summary, our identification of Merkel cell polyomavirus large T antigen expression in a subset of Merkel cell carcinoma and lack of findings in combined Merkel cell carcinomas and non-Merkel cell carcinoma lesions concur with

    Background Primary small cell carcinoma of the esophagus is rare. Although surgery is successful in eradicating local tumor, the five-year survival rate of patients with primary small cell carcinoma of the esophagus after resection is lower than that of patients with primary squamous cell carcinoma of the esophagus. The purpose of this study was to analyze the clinical manifestations, pathological features and treatment of primary small cell carcinoma of the esophagus.Methods A total of 73 patients with primary small cell carcinoma of the esophagus who had been treated by surgery from 1984 to 2003 were analyzed retrospectively.Results In this series, the overall resection rate was 94.5% (69/73), the radical resection rate 89.0% (65/73) and the operative mortality 1.4% (1/73). The 1-, 3- and 5-year survival rates of patients were 50.7%, 13.7% and 8.2%,respectively.Conclusions Primary small cell carcinoma of the esophagus is rare with a poor prognosis. Surgical resection is the leading method for patients with stage Ⅰ or Ⅱ primary small cell carcinoma of the esophagus. Postoperative chemotherapy is beneficial to these patients. The patients of stage Ⅲ or Ⅳ should be given chemotherapy and radiation therapy.

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells. The presence of intra-tumoural CD8+ lymphocytes reportedly predicts better MCC-specific survival. In this study, the distribution of inflammatory cells and properties of CD8+ T lymphocytes within 20 primary MCC specimens were characterised using immunohistochemistry and multicolour immunofluorescent staining coupled to confocal microscopy. CD8+ cells and CD68+ macrophages were identified in 19/20 primary MCC. CD20+ B cells were present in 5/10, CD4+ cells in 10/10 and FoxP3+ cells in 7/10 specimens. Only two specimens had almost no inflammatory cells. Within specimens, inflammatory cells followed the same patchy distribution, focused at the edge of sheets and nodules and, in some cases, more intense in trabecular areas. CD8+ cells were outside vessels on the edge of tumour. Those few within malignant sheets typically lined up in fine septa not contacting MCC cells expressing MCPyV large T antigen. The homeostatic chemokine CXCL12 was expressed outside malignant nodules whereas its receptor CXCR4 was identified within tumour but not on CD8+ cells. CD8+ cells lacked CXCR3 and granzyme B expression irrespective of location within stroma versus malignant nodules or of the intensity of the intra-tumoural infiltrate. In summary, diverse inflammatory cells were organised around the margin of malignant deposits suggesting response to aberrant signaling, but were unable to penetrate the tumour microenvironment itself to enable an immune response against malignant cells or their polyomavirus.

  6. Is there any role of mast cell density and microvessel density in cervical squamous cell carcinoma? A histologic study with special reference to CD-34 immunomarker staining

    2014-01-01

    Full Text Available Background: Mast cells are involved in induction of angiogenesis in the early-stages of tumor development and in modulating blood vessel growth in the later stages of tumor progression. Aims and Objectives: This study was carried out to evaluate the association between mast cell density (MCD and microvessel density (MVD in carcinoma in situ (CIS, microinvasive carcinoma (CA and invasive squamous cell CA of cervix. Materials and Methods: Six cases of CIS, four cases of microinvasive CA and 38 cases of invasive CA were studied over a period of 2 years from August, 2011 to June, 2013. Ten control samples were included in the study. Routine histologic examination was done. Toluidine blue stain was used for MCD determination. Immunohistochemical analysis with CD-34 was done for assessing MVD. Student′s t-test was used to calculate the statistical significance of MCD and MVD. Results: Both MCD and MVD increased from normal samples through CIS to invasive cervical CA. In the four cases of microinvasive CA, the MCD and MVD were more than that of the control samples, but less than that of the six cases of CIS. Conclusion: There is a correlation between mast cell accumulation and angiogenesis in CIS, microinvasive CA and invasive cervical squamous cell CA. MCD and MVD in invasive CA exceed those in CIS and microinvasive CA. It gives us an opportunity to postulate that therapeutic strategies against mast cell mediators and angiogenesis may be of benefit in patients of early-stage cervical CA.

    Most penile cancers are squamous cell carcinoma (SCC) originating in the epithelium covering glans, coronal sulcus, and foreskin. Several histologic subtypes have been described, each with distinctive clinicopathologic and outcome features. The most common subtype is the usual SCC, representing one half to two thirds of penile carcinomas. Penile verruciform tumors encompass verrucous, warty (condylomatous), and papillary, not otherwise specified, carcinomas. As a group, verruciform tumors are low grade, with low metastatic and mortality rates. In contrast, basaloid and sarcomatoid carcinomas are among the most aggressive penile tumors. Other SCC variants, such as carcinoma cuniculatum and pseudohyperplastic, adenosquamous and acantholytic carcinomas, are rare. The most relevant clinicopathologic and outcome features are outlined for each of these SCC subtypes, and an algorithm that might aid the pathologist in the histologic classification is presented. In addition, recommendations for handling penile cancer specimens, frozen section specimens, and pathology reports are provided.

    Full Text Available Abstract Background Novel therapies are necessary to improve outcomes for patients with squamous cell carcinomas (SCC of the head and neck. Historically, vaccinia virus was administered widely to humans as a vaccine and led to the eradication of smallpox. We examined the therapeutic effects of an attenuated, replication-competent vaccinia virus (GLV-1h68 as an oncolytic agent against a panel of six human head and neck SCC cell lines. Results All six cell lines supported viral transgene expression (β-galactosidase, green fluorescent protein, and luciferase as early as 6 hours after viral exposure. Efficient transgene expression and viral replication (>150-fold titer increase over 72 hrs were observed in four of the cell lines. At a multiplicity of infection (MOI of 1, GLV-1h68 was highly cytotoxic to the four cell lines, resulting in ≥ 90% cytotoxicity over 6 days, and the remaining two cell lines exhibited >45% cytotoxicity. Even at a very low MOI of 0.01, three cell lines still demonstrated >60% cell death over 6 days. A single injection of GLV-1h68 (5 × 106 pfu intratumorally into MSKQLL2 xenografts in mice exhibited localized intratumoral luciferase activity peaking at days 2–4, with gradual resolution over 10 days and no evidence of spread to normal organs. Treated animals exhibited near-complete tumor regression over a 24-day period without any observed toxicity, while control animals demonstrated rapid tumor progression. Conclusion These results demonstrate significant oncolytic efficacy by an attenuated vaccinia virus for infecting and lysing head and neck SCC both in vitro and in vivo, and support its continued investigation in future clinical trials.

    Renal cell carcinoma (RCC) is a metabolic disease, being characterized by the dysregulation of metabolic pathways involved in oxygen sensing (VHL/HIF pathway alterations and the subsequent up-regulation of HIF-responsive genes such as VEGF, PDGF, EGF, and glucose transporters GLUT1 and GLUT4, which justify the RCC reliance on aerobic glycolysis), energy sensing (fumarate hydratase-deficient, succinate dehydrogenase-deficient RCC, mutations of HGF/MET pathway resulting in the metabolic Warburg shift marked by RCC increased dependence on aerobic glycolysis and the pentose phosphate shunt, augmented lipogenesis, and reduced AMPK and Krebs cycle activity) and/or nutrient sensing cascade (deregulation of AMPK-TSC1/2-mTOR and PI3K-Akt-mTOR pathways). We analyzed the key metabolic abnormalities underlying RCC carcinogenesis, highlighting those altered pathways that may represent potential targets for the development of more effective therapeutic strategies.

    This review provides an overview of the incidence of renal cell carcinoma (RCC) and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses). The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Recent developments in chemotherapy have resulted in several new drug treatments for metastatic renal cell carcinoma (RCC). These therapies have shown improved progression-free survival and are applicable to many more patients than the conventional cytokine-based treatments for metastatic RCC. Consequently imaging is playing a greater part in the management of such patients. Computed tomography (CT) remains the primary imaging modality with other imaging modalities playing a supplementary role. CT is used in the diagnosis and staging of metastatic RCC. It is used in the follow-up of patients after nephrectomy, in assessing the extent of metastatic disease, and in evaluating response to treatment. This review looks at the role of CT in patients with metastatic RCC and describes the appearances of metastatic RCC before and following systemic therapy.

    Tuberculosis is still a significant problem in developing countries. Cutaneous forms of tuberculosis account for approximately 10% of all cases of extrapulmonary tuberculosis. Cutaneous tuberculosis may be because of true infection with Mycobacterium tuberculosis or because of tuberculids. Tuberculids are immunological reactions to haematogenously spread antigenic components of M. tuberculosis. True cutaneous tuberculosis may be because of inoculation or haematogenous spread of M. tuberculosis to the skin. Lupus vulgaris is the commonest form of true cutaneous tuberculosis. Other forms of true cutaneous tuberculosis are tuberculous chancre, tuberculosis verrucosa cutis, scrofuloderma, periorificial tuberculosis and miliary tuberculosis of the skin. Lupus vulgaris is usually chronic and progressive. It occurs in patients with moderate to high immunity against M. tuberculosis as evidenced by strongly positive tuberculin test. Long-standing cases of lupus vulgaris may be complicated by squamous cell carcinoma (SCC). We describe a patient who had undiagnosed lupus vulgaris for 35 years until she developed SCC on the lesion of lupus vulgaris.

    Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

    Full Text Available Abstract Background The head and neck/oral squamous cell carcinoma (HNOSCC is a diverse group of cancers, which develop from many different anatomic sites and are associated with different risk factors and genetic characteristics. The oral tongue squamous cell carcinoma (OTSCC is one of the most common types of HNOSCC. It is significantly more aggressive than other forms of HNOSCC, in terms of local invasion and spread. In this study, we aim to identify specific transcriptomic signatures that associated with OTSCC. Results Genome-wide transcriptomic profiles were obtained for 53 primary OTSCCs and 22 matching normal tissues. Genes that exhibit statistically significant differences in expression between OTSCCs and normal were identified. These include up-regulated genes (MMP1, MMP10, MMP3, MMP12, PTHLH, INHBA, LAMC2, IL8, KRT17, COL1A2, IFI6, ISG15, PLAU, GREM1, MMP9, IFI44, CXCL1, and down-regulated genes (KRT4, MAL, CRNN, SCEL, CRISP3, SPINK5, CLCA4, ADH1B, P11, TGM3, RHCG, PPP1R3C, CEACAM7, HPGD, CFD, ABCA8, CLU, CYP3A5. The expressional difference of IL8 and MMP9 were further validated by real-time quantitative RT-PCR and immunohistochemistry. The Gene Ontology analysis suggested a number of altered biological processes in OTSCCs, including enhancements in phosphate transport, collagen catabolism, I-kappaB kinase/NF-kappaB signaling cascade, extracellular matrix organization and biogenesis, chemotaxis, as well as suppressions of superoxide release, hydrogen peroxide metabolism, cellular response to hydrogen peroxide, keratinization, and keratinocyte differentiation in OTSCCs. Conclusion In summary, our study provided a transcriptomic signature for OTSCC that may lead to a diagnosis or screen tool and provide the foundation for further functional validation of these specific candidate genes for OTSCC.

    The coexistence of two malignancies is rarely seen. A little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. Several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. Here, we aim to describe a patient who had multiple myeloma and in his work up renal cell carcinoma was found out incidentally. We would like to create awareness among clinicians for the coincidence of Renal cell carcinoma and Multiple myeloma.

    Full Text Available Primary squamous cell carcinoma of renal pelvis is rare clinical entity with only few cases have been reported in the literature. It is usually associated with long standing renal calculi. Insidious onset of symptom and inconclusive clinical and radiological features leads to locally advanced or metastatic disease at presentation; resulting in poor prognosis. Here we are reporting two cases of squamous cell carcinoma of kidney having renal calculi to highlight its clinical presentation and to document the association of squamous cell carcinoma in longstanding nephrolithiasis due to its rarity.

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

Median age was 46 years (21- 68). Histology was squamous cell carcinoma in 93% and glandular carcinoma in 7%. Average external radiation dose was 44Gy (20-50). Ninety three percent of patients had at least 3 cycles of chemotherapy and 46,5% received the planned 5 cycles. On the operative specimens, there was 62,5% complete response and only 7 pelvic node involvement (17,5%). Four postoperative complications were noted (one vascular injury, one urinary fistula, one phlebitis and one lymph collection). Preoperative combined radiotherapy and chemotherapy in the early bulky stages of uterine cervix cancer is well tolerated and "gives" a high rate of sterilisation. There was no increase in surgical morbidity.

    Full Text Available Renal cell carcinomas arise from the nephron but are heterogeneous in disease biology, clinical behavior, prognosis, and response to systemic therapy. Development of patient-specific in vitro models that efficiently and faithfully reproduce the in vivo phenotype may provide a means to develop personalized therapies for this diverse carcinoma. Studies to maintain and model tumor phenotypes in vitro were conducted with emerging three-dimensional culture techniques and natural scaffolding materials. Human renal cell carcinomas were individually characterized by histology, immunohistochemistry, and quantitative PCR to establish the characteristics of each tumor. Isolated cells were cultured on renal extracellular matrix and compared to a novel polysaccharide scaffold to assess cell-scaffold interactions, development of organoids, and maintenance of gene expression signatures over time in culture. Renal cell carcinomas cultured on renal extracellular matrix repopulated tubules or vessel lumens in renal pyramids and medullary rays, but cells were not observed in glomeruli or outer cortical regions of the scaffold. In the polysaccharide scaffold, renal cell carcinomas formed aggregates that were loosely attached to the scaffold or free-floating within the matrix. Molecular analysis of cell-scaffold constructs including immunohistochemistry and quantitative PCR demonstrated that individual tumor phenotypes could be sustained for up to 21 days in culture on both scaffolds, and in comparison to outcomes in two-dimensional monolayer cultures. The use of three-dimensional scaffolds to engineer a personalized in vitro renal cell carcinoma model provides opportunities to advance understanding of this disease.

    Clear-cell renal cell carcinoma (CC-RCC) is the most common primary kidney malignancy, yet this morphology is not unique to renal primary tumors, as clear-cell variants of numerous nonrenal carcinomas of varying lineages exist. Therefore, because of CC-RCC's ability to metastasize to nearly any anatomic location, ancillary studies such as immunohistochemistry are often needed to establish the diagnosis. Despite CD10 and renal cell carcinoma monoclonal antibody (RCCma) being touted as sensitive and specific markers, some have suggested that more recent stains including PAX-2, PAX-8, or adipophilin (ADP) are more robust markers of CC-RCC. In this study, 26 cases of CC-RCC, and 51 nonrenal carcinomas with clear-cell histomorphology (CCM) were stained with CD10, RCCma, PAX-2, PAX-8, and ADP. CA-125 was also included to help distinguish CC-RCC from Müllerian clear-cell carcinomas, due the known expression of PAX-2 and PAX-8 in both these entities. RCCma highlighted 77% of CC-RCC and 27% of the CCM group, whereas CD10 was positive in 85% and 25%, respectively. ADP highlighted all CC-RCC and 45% of CCMs. PAX-2 was positive in 81% of CC-RCC and 24% of CCM, whereas PAX-8 stained 100% of CC-RCC and 39% of CCM. Müllerian-derived tumors (clear-cell carcinomas of the ovary, vagina, and cervix) were positive with PAX-2 and PAX-8 in 69% and 100% of cases, respectively. No cases of CC-RCC stained with CA-125, whereas 88% of the Müllerian-derived tumors were positive. In summary, although new markers such as PAX-2 and PAX-8 tend to be more sensitive markers of CC-RCC, they lose specificity when Müllerian tumors are included. Inclusion of a classic renal marker such as CD10 or RCCma in the immunohistochemical panel, as well as CA-125 obviates this difficulty.

    The goal of this study is to use gold nanoparticle as a diagnostic agent to detect human squamous carcinoma cells. Gold nanoparticles were synthesized and the gold nanoparticle size was 34.3 ± 6.2 nm. Based on the over-expression of epidermal growth factor receptor (EGFR) biomarkers in squamous carcinoma cells, we hypothesized that EGFR could be a feasible biomarker with a target moiety for detection. We further modified polyclonal antibodies of EGFR on the surface of gold nanoparticles. We found selected squamous carcinoma cells can be selectively detected using EGFR antibody-modified gold nanoparticles via receptor-mediated endocytosis. Cell death was also examined to determine the survival status of squamous carcinoma cells with respect to gold nanoparticle treatment and EGFR polyclonal antibody modification.

    Background The aim of this study was to investigate DNA content and expression of c-erbB-2, PS2, and prostate-specific antigen (PSA) proteins in breast carcinomas with neuroendocrine (NE) cell differentiation.Methods Chromogranin, c-erbB-2, PS2, and PSA in 131 samples of breast cancer were detected immunohistochemically. Classic Feulgen staining image analysis techniques were used to quantify DNA content in 81 of the breast cancer samples.Results The c-erbB-2 positive rate in breast carcinoma samples containing neuroendocrine cells was 37.5% and the rate of high expression of c-erbB-2 (++ or +++) was 33.3%, both significantly lower than that in breast carcinomas without neuroendocrine cells (62.6% and 68.7%, respectively, P 5c aneuploidy cells, and rate of aneuploidy among cells were all lower than that in NE (-) breast carcinomas (P<0.01). In NE (+) grade I or II breast carcinomas, these indices were also all lower than that in the NE (-) breast carcinoma samples (P<0.01).Conclusion Breast carcinomas with neuroendocrine differentiation have a lower rate of malignancy. Neuroendocrine differentiation could serve as a prognostic marker in clinical practice.

    Full Text Available Neuroendocrine carcinomas (NEC of the female genital tract are aggressive and rare tumors that usually involve the cervix and ovary, and are seen rarely in the endometrium in perimenopausal or postmenopausal women. We presented a case of a73 year-old postmenopausal woman with vaginal bleeding and abdominal pain. A subsequent computerized tomography (CT scan of pelvis showed an enlarged uterus (20,0 × 12,0 cm with para-aortic and pelvic lymph node metastases.

The pathological diagnosis was primary small cell carcinoma (SCC combined with endometrioid carcinoma of uterine corpus. Her final FIGO stage was IVB. Three months after surgery CT-total body showed a metastasis to left lung of SCC. Because the small-cell component of endometrial tumor showed a strong positivity for TTF1 as pulmonary counterpart a differential diagnosis with a primary small cell carcinoma of the lung should be made. Identifying an appropriate therapeutic management for SCC of endometrium is challenging since these are extremely rare tumors. An optimal initial therapeutic approach to this rare disease, especially at an advanced stage, has not yet been clearly defined. However, in these a multidisciplinary therapy, including surgery, chemotherapy, and radiotherapy represent until this time the only therapeutic option.

    Clear cell papillary renal cell carcinoma (CCPRCC) is a low-grade renal neoplasm with morphological characteristics mimicking both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma (PRCC). However, despite some overlapping features, their morphological, immunohistochemical, and molecular profiles are distinct. Micro-RNAs (miRNAs) are small noncoding RNAs that play a crucial role in regulating gene expression and are involved in various biological processes, including cancer development. To better understand the biology of this tumor, we aimed to analyze the miRNA expression profile of a set of CCPRCC using microarray and quantitative reverse transcription-polymerase chain reaction. A total of 15 cases diagnosed as CCPRCC were used in this study. Among the most differentially expressed miRNA in CCPRCC, we found miR-210, miR-122, miR-34a, miR-21, miR-34b*, and miR-489 to be up-regulated, whereas miR-4284, miR-1202, miR-135a, miR-1973, and miR-204 were down-regulated compared with normal renal parenchyma. To identify consensus of differentially regulated miRNA between CCPRCC, CCRCC, and PRCC, we additionally determined differential miRNA expression using 2 publically available microarray data sets from the NCBI Gene Expression Omnibus database (GSE41282 and GSE3798). This comparison revealed that the miRNA expression profile of CCPRCC shows some overlapping characteristics between CCRCC and PRCC. Moreover, CCPRCC lacks dysregulation of important miRNAs typically associated with aggressive behavior. In summary, we describe the miRNA expression profile of a relatively infrequent type of renal cancer. Our results may help in understanding the molecular underpinning of this newly recognized entity.

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

    Renal cell carcinoma with rhabdoid differentiation (RCC-R) has an aggressive biologic behavior and poor prognosis. A recent consensus statement of the International Society of Urological Pathology (ISUP) proposed a nucleolar grading system (ISUP grade) for RCC to replace Fuhrman system and recommended reporting the presence of rhabdoid differentiation and considering tumors with rhabdoid differentiation to be ISUP Grade 4. We report a case of incidentally detected clear cell RCC-R in a 52-year-old man. This is one of the earliest cases of RCC-R (pT1b) detected and first such case from Indian subcontinent.

    Merkel cell carcinoma (MCC), being a small cell carcinoma, would be expected to be sensitive to radiation. Clinical analysis of patients at our center, especially those with macroscopic disease, would suggest the response is quite variable. We have recently established a number of MCC cell lines from patients prior to radiotherapy, and for the first time are in a position to determine their sensitivity under controlled conditions. Some of the MCC lines grew as suspension cultures and could not be single cell cloned; therefore, it was not possible to use clonogenic survival for all cell lines. A tetrazolium based (MTT) assay was used for these lines, to estimate cell growth after {gamma} irradiation. Control experiments were conducted on lymphoblastoid cell lines (LCL) and the adherent MCC line, MCC13, to demonstrate that the two assays were comparable under the conditions used. We have examined cell lines from MCC, small cell lung cancer (SCLC), malignant melanomas, Epstein Barr virus (EBV) transformed lymphocytes (LCL), and skin fibroblasts for their sensitivity to {gamma} irradiation using both clonogenic cell survival and MTT assays. The results show that the tumor cell lines have a range of sensitivities, with melanoma being more resistant (surviving fraction at 2 Gy (SF2) 0.57 and 0.56) than the small cell carcinoma lines, MCC (SF2 range 0.21-0.45, mean SF2 0.30, n = 8) and SCLC (SF2 0.31). Fibroblasts were the most sensitive (SF2 0.13-0.20, mean 0.16, n = 5). The MTT assay, when compared to clonogenic assay for the MCC13 adherent line and the LCL, gave comparable results under the conditions used. Both assays gave a range of SF2 values for the MCC cell lines, suggesting that these cancers would give a heterogeneous response in vivo. The results with the two derivative clones of MCC14 (SF2 for MCC14/1 0.38, MCC14/2 0.45) would further suggest that some of them may develop resistance during clonogenic evolution. 25 refs., 3 figs., 1 tab.

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

    Fibroblast growth factor receptors (FGFRs) have been implicated in various forms of human hyperproliferative disorders such as cancers of the cervix and bladder. We investigated the expression pattern of FGFR4 and the clinical significance of the recently identified Gly/Arg polymorphism (388) in head and neck squamous cell carcinomas (HNSCCs) of the oral cavity and the oropharynx. Sections from 104 paraffin-embedded tumors were analyzed by a restriction fragment length polymorphism-based method to determine the FGFR4 genotypes. Protein expression was investigated immunohistochemically and graded into a low, intermediate, or high degree of staining. FGFR4 expression was scored as high in 17, as intermediate in 59 and as low in 28 cases. The FGFR4 Arg388 allele was found in 59 tumors, 46 of them having heterozygous and 13 homozygous genotypes. High expression of the FGFR4 Arg388 allele was significantly associated with reduced overall survival (p = 0.032) and with an advanced tumor stage (p = 0.023), whereas expression of the FGFR4 Gly388 had no impact on disease progression. Our findings indicate that high expression of FGFR4 in connection with the Arg388 allele is associated with poor clinical outcome and support the significance of FGFR4 as a diagnostic marker and a target for therapeutic intervention in human HNSCC.

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

    We report three kowari (Dasyuroides byrnei) with squamous cell carcinoma affecting the gingiva. These cases occurred in rapid succession in a related group of individuals of similar age, suggesting a familial tendency to this condition and a typical age of presentation. Other conditions affecting the oral cavity can mimic the appearance of oral squamous cell carcinoma in this species, and so knowledge of this condition can assist the veterinarian in making rapid decisions regarding prognosis and improving the welfare of these animals.

    Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine malignancy that is associated with a poor prognosis. The pathogenesis of MCC is not well understood, and despite a recent plethora of mutational analyses, we have yet to find a set of signature mutations implicated in the majority of cases. Mutations, including TP53, Retinoblastoma and PIK3CA, have been documented in subsets of patients. Other mechanisms are also likely at play, including infection with the Merkel cell polyomavirus in a subset of patients, dysregulated immune surveillance, epigenetic alterations, aberrant protein expression, posttranslational modifications and microRNAs. In this review, we summarize what is known about MCC genetic mutations and chromosomal abnormalities, and their clinical significance. We also examine aberrant protein function and microRNA expression, and discuss the therapeutic and prognostic implications of these findings. Multiple clinical trials designed to selectively target overexpressed oncogenes in MCC are currently underway, though most are still in early phases. As we accumulate more molecular data on MCC, we will be better able to understand its pathogenic mechanisms, develop libraries of targeted therapies, and define molecular prognostic signatures to enhance our clinicopathologic knowledge.

    Full Text Available Renal cell carcinoma (RCC accounts for 90% of all kidney cancers. Due to poor diagnosis, high resistance to the systemic therapies and the fact that most RCC cases occur sporadically, current research switched its focus on studying the molecular mechanisms underlying RCC. The aim is the discovery of new effective and less toxic anti-cancer drugs and novel diagnostic markers. Besides the PI3K/Akt/mTOR, HGF/Met and VHL/hypoxia cellular signaling pathways, the involvement of the Wnt/β-catenin pathway in RCC is commonly studied. Wnt signaling and its targeted genes are known to actively participate in different biological processes during embryonic development and renal cancer. Recently, studies have shown that targeting this pathway by alternating/inhibiting its intracellular signal transduction can reduce cancer cells viability and inhibit their growth. The targets and drugs identified show promising potential to serve as novel RCC therapeutics and prognostic markers. This review aims to summarize the current status quo regarding recent research on RCC focusing on the involvement of the Wnt/β-catenin pathway and how its understanding could facilitate the identification of potential therapeutic targets, new drugs and diagnostic biomarkers.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. The infectivity of Merkel cell polyomavirus (MCPyV), an apparent agent in MCC development, may be exacerbated with impaired immune responses. This paper reviews relevant data regarding the role of immunosuppression in the development of MCC and describes modes of immunodeficient states. Because of the inherently low incidence rate of MCC, several case studies and series are also briefly mentioned to provide a more comprehensive summary of MCC in the setting of immunosuppression. We describe immunosuppressed patients who have experienced excessive UV radiation, organ transplantation, human immunodeficiency virus infection/AIDS, autoimmune diseases, and lymphoproliferative disorders. Iatrogenic forms of immunosuppression are also highlighted. Studies that quantify risks consistently report that individuals with a history of solid organ transplantation, autoimmune diseases, AIDS, and/or lymphoproliferative diseases have a significantly elevated risk of developing MCC. Overall, immunocompromised patients also appear to have an early onset and more aggressive course of MCC, with poorer outcomes. Recommendations for multidisciplinary approaches are proposed to effectively prevent and manage MCC in these patients.

    AIM: To investigate the density of mast cells (MCs) in human hepatocellular carcinoma (HCC), and to determine whether the MCs density has any correlations with histopathological grading, staging or some baseline patient characteristics.METHODS: Tissue sections of 22 primary HCCs were histochemically stained with toluidine blue, in order to be able to quantify the MCs in and around the neoplasm using a computer-assisted image analysis system. HCC was staged and graded by two independent pathologists. To identify the sinusoidal capillarisation of each specimen 3μm thick sections were histochemically stained with sirius red, and semi-quantitatively evaluated by two independent observers. The data were statistically analysed using Spearman′s correlation and Student′s t-test when appropriate.RESULTS: MCs density did not correlate with the age or sex of the patients, the serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, or the stage or grade of the HCC. No significant differences were found between the MCs density of the patients with and without hepatitis C virus infection, but they were significantly higher in the specimens showing marked sinusoidal capillarisation.CONCLUSION: The lack of any significant correlation between MCs density and the stage or grade of the neoplastic lesions suggests that there is no causal relationship between MCs recruitment and HCC. However, as capillarisation proceeds concurrently with arterial blood supply during hepatocarcinogenesis, MCs may be considered of primary importance in the transition from sinusoidal to capillary-type endothelial cells and the HCC growth.

    The study of mitochondria in situ has recently been facilitated through the use of rhodamine 123, a mitochondrial-specific fluorescent dye. It has been found to be nontoxic when applied for short periods to a variety of cell types and has thus become an invaluable tool for examining mitochondrial morphology and function in the intact living cell. In this report, however, we demonstrate that with continuous exposure, rhodamine 123 selectively kills carcinoma as compared to normal epithelial cells grown in vitro. At doses of rhodamine 123 which were toxic to carcinoma cells, the conversion of mitochondrial-specific to cytoplasmic-nonspecific localization of the drug was observed prior to cell death. At 10 microgram/ml, greater than 50% cell death occurred within 7 days in all nine of the carcinoma cell types and lines of different origin studied, while six of six normal epithelial cell types and lines remained unaffected. Cotreating carcinoma cells with 2-deoxyglucose and rhodamine 123 enhanced the inhibition of growth by rhodamine 123 alone in clonogenic survival assays. The observation of the selective toxicity of rhodamine 123 appears to be unique in view of the absence of selective toxicity reported in vitro for the various antitumor agents currently in clinical use. Preliminary results with rhodamine 123 in animal tumor systems indicate antitumor activity for carcinomas.

    Full Text Available Background: Carcinoma of cervix is the most common malignancy in female and a major public health problem worldwide. It is the leading cause of death from cancer among women in low resource settings. In Bangladesh, mortality rate is high as most of the cases with cervical cancer are diagnosed in advanced stage. World Health Organization considers cervical cancer as a preventable disease as it can be identified in preinvasive stage. Considerable efforts have been given in detection and treatment of the condition all over the world. A number of cervical cancer screening tests are available. Among them, visual inspection of cervix with acetic acid is rational and can be competently performed by physicians with proper training. Objective: To find out the feasibility of the visual inspection of cervix with acetic acid for the detection of the precancerous lesions of the cervix in our country. Materials and Methods: This cross sectional, analytical study was carried out among the patients attending the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU who were VIA positive and sent for colposcopy in the colposcopy clinic in the department of Obstetrics and Gynecology in BSMMU from June to December 2004. Two hundred samples were considered for this study. Results: Out of 200 cases, colposcopically 85% had CIN and invasive lesions, 4% had inflammatory lesions while 11% had normal findings. Colposcopy directed punch biopsy revealed positive lesions in 81%, 4% had inflammatory lesions while 15% had normal findings. Conclusion: The study concluded that VIA and colposcopy are the important methods in the evaluation of cervical premalignancy. VIA may be an important tool for screening of cervical cancer in low resource settings as it is simple, easy to perform and cost-effective. After screening, VIA positive cases must be referred for colposcopic evaluation. We can screen cervical cancer by VIA all over the country and thus reduce

    Metastatic lung carcinomas with clear cell morphology can be confused with primary ovarian clear cell carcinomas. We performed immunohistochemical stains in 14 cases of non-small cell lung carcinomas with clear cell features and 14 cases of ovarian clear cell carcinomas using a panel of markers, including thyroid transcription factor 1 (TTF-1), carcinoembryonic antigen (CEA), Wilms tumor gene 1, octamer-binding transcription factor 4 (OCT-4), cancer antigen 125 (CA-125), estrogen receptor, and progesterone receptor. Among non-small cell lung carcinomas with clear cell features, 87.5% of adenocarcinomas (or 50% overall frequency in lung carcinomas) were positive for TTF-1, whereas none of the ovarian clear cell carcinomas were positive (P = 0.002). All 14 ovarian clear cell carcinomas stained for CA-125 as compared with 1 non-small cell lung carcinoma (P < 0.001). On the other hand, 85% of non-small cell lung carcinomas stained for CEA, whereas none of the ovarian clear cell carcinomas did (P < 0.001). Interestingly, 4 ovarian clear cell carcinomas (28%) showed positive staining for the germ cell marker OCT-4. Either lung or ovarian carcinomas stained for Wilms tumor gene 1, estrogen receptor, or progesterone receptor very infrequently; and the difference between the 2 groups was not statistically significant. Our results suggest that an immunohistochemical panel consisting of TTF-1, CEA, CA-125, and OCT-4 is helpful in distinguishing most pulmonary and ovarian carcinomas with clear cell features.

    Various imaging modalities are available for the diagnosis, staging and response evaluation of patients with renal cell carcinoma(RCC). While contrast enhanced computed tomography(CT) is used as the standard of imaging for size, morphological evaluation and response assessment in RCC, a new functional imaging technique like perfusion CT(p CT), goes down to the molecular level and provides new perspectives in imaging of RCC. p CT depicts regional tumor perfusion and vascular permeability which are indirect parameters of tumor angiogenesis and thereby provides vital information regarding tumor microenvironment. Also response evaluation using p CT may predate the size criteria used in Response Evaluation Criteria in Solid Tumors, as changes in the perfusion occurs earlier following tissue kinase inhibitors before any actual change in size. This may potentially help in predicting prognosis, better selection of therapy and more accurate and better response evaluation in patients with RCC. This article describes the techniques and role of p CT in staging and response assessment in patients with RCCs.

    Full Text Available To determine whether viral infections are related to renal cell carcinoma (RCC, we studied 49 patients with RCC (29 patients were males with age ranging from 30 to 81 years and a mean of 57.5 years; 20 patients were females with age ranging from 36 to 70 years with a mean of 58.4 years and 16 non-neoplastic kidney patients as controls. Tissues specimens from study patients and controls were examined by nested polymerase chain reaction (PCR to determine the presence of DNA of several viruses including human papilloma virus (HPV, Epstein-Barr virus (EBV, and polyoma viruses (BKV and JCV. Our results revealed that 7 of 49 (14.29% RCC tissue specimens had HPV DNA compared with none of 16 non-cancer control subjects. Regarding the HPV types, all the positive results were high-risk HPV types (type 16 in three and 18 in four patients. The present study suggests that HPV infection, especially high-risk types, is associated with RCC. However, more studies are necessary to demonstrate the molecular oncogenic processes involved in this association.

    Temporal bone squamous cell carcinoma (TBSCC) is rare and poses difficulties in diagnosing, staging and management. We describe a case series with six patients who were diagnosed TBSCC, from January 2009 to June 2014, with median age of 62 years old. All patients presented with blood-stain discharge and external auditory canal mass, showing that these findings should highly alert the diagnosis of TBSCC. Three patients staged T3 and another three with T4 disease. High-resolution CT (HRCT) temporal findings were noted to be different from intraoperative findings and therefore we conclude that MRI should be done to look for middle ear involvement or other soft tissue invasion for more accurate staging. Lateral temporal bone resection (LTBR) and parotidectomy was done for four patients with or without neck dissection. Patients with positive margin, perineural invasion or parotid and glenoid involvement carry poorer prognosis and postoperative radiotherapy may improve the survival rate. One patient had successful tumor resection via piecemeal removal approach in contrast with the recommended en bloc resection shows that with negative margin achieved, piecemeal removal approach can be a good option for patients with T2-3 disease. In general, T4 tumor has dismal outcome regardless of surgery or radiotherapy given.

    Renal cell carcinoma (RCC) consists of approximately 85-90% of renal masses, and its incidence is increasing due to widespread use of modern imaging modalities such as ultrasonography or computed tomography. Computed tomography has served an important role in the diagnosis and staging of RCC; however, recent advances in magnetic resonance imaging (MRI) techniques have considerably improved our ability to predict tumor biology beyond the morphologic assessment. Multiparametric MRI protocols include standard sequences tailored for the morphologic evaluation and acquisitions that provide information about the tumor microenvironment such as diffusion-weighted imaging and dynamic contrast-enhanced MRI. The role of multiparametric MRI in the evaluation of RCC now extends to preoperative characterization of RCC subtypes, histologic grade, and quantitative assessment of tumor response to targeted therapies in patients with metastatic disease. Herein, the clinical applications and recent advances in MRI applied to RCC are reviewed along with its merits and demerits. We aimed to review MRI techniques and image analysis that can improve the management of patients with RCC. Familiarity with the advanced MRI techniques and various imaging findings of RCC would also facilitate optimal clinical recommendations for patients.

    Background Basal cell carcinoma (BCC) is the commonest periorbital tumour. Mohs' micrographic surgery and secondary reconstruction is the therapeutic gold standard for periorbital BCC. In cases of inoperability for any reason, therapeutic alternatives are needed. Since the approval of vismodegib, an orally administered, targeted BCC therapy is available. Nevertheless there is little information on the use of vismodegib for periorbital BCC. Patients and Methods In a retrospective study, we analysed the data of 4 patients treated with vismodegib since 2014. The patients' mean age before starting therapy was 87 years. The mean maximum tumour diameter was 22.0 mm. Results The median follow-up was 17 months. The median treatment duration was 7.5 months. In 75 % of patients, complete clinical remission of BCC was achieved. In 25 % of patients, interim stabilisation of tumour growth was possible. The most common side effect of therapy was muscle spasm. Conclusion Vismodegib is an effective treatment option for patients with periorbital BCC, in whom surgical treatment is not possible for any reason.

Tumor resection revealed a tumor consistent with low grade adenocarcinoma that had eosinophilic, microvacuolar cytoplasm with distinct basophilic granules staining with PASD and mucicarmine. The diagnosis of MASC was confirmed with stains for GCDF-15, mammoglobin, and S100 and FISH consistent with a t(12;15 translocation. Relying on the absence of cytoplasmic granules as a feature to distinguish ACC from MASC is a diagnostic pitfall.

  9. Vismodegib (ERIVEDGE°) In basal cell carcinoma: too many unknowns.

    Basal cell carcinomas are the most common skin cancers. They are usually localised and carry a good prognosis. There is no standard treatment for the rare patients with metastatic basal cell carcinoma or very extensive basal cell carcinoma for whom surgery or radiotherapy is inappropriate. Vismodegib, a cytotoxic drug, is claimed to prevent tumour growth by inhibiting a pathway involved in tissue repair and embryogenesis. It has been authorised in the European Union for patients with metastatic or locally advanced and extensive basal cell carcinoma. Clinical evaluation of vismodegib is based on a non-comparative clinical trial involving 104 patients, providing only weak evidence. Twenty-one months after the start of the trial, 7 patients with metastases (21%) and 6 patients with advanced basal cell carcinoma (10%) had died. Given the lack of a placebo group, there is no way of knowing whether vismodegib had any effect, positive or negative, on survival. There were no complete responses among patients with metastases, but about one-third of them had partial responses. Among the 63 patients with locally advanced basal cell carcinoma, there were 14 complete responses and 16 partial responses. The recurrence rate in patients with complete responses was not reported. Similar results were reported in two other uncontrolled trials available in mid-2014. Vismodegib has frequent and sometimes serious adverse effects, including muscle spasms, fatigue and severe hyponatraemia. Cases of severe weight loss, alopecia, ocular disorders, other cancers (including squamous cell carcinoma) and anaemia have also been reported. More data are needed on possible hepatic and cardiovascular adverse effects. A potent teratogenic effect was seen in experimental animals. As vismodegib enters semen, contraception is mandatory for both men (condoms) and women. In practice, vismodegib has frequent and varied adverse effects, some of which are serious, while its benefits are poorly documented

    Full Text Available Circulating tumor cells (CTCs are those cells present in the blood and have antigenic and/or genetic characteristics of a specific tumor type. CTCs can be detected in the peripheral blood of cancer patients. Various techniques are available for detection of CTCs, which provide evidence for future metastasis. CTCs may provide new insight into the biology of cancer and process of metastasis in oral squamous cell carcinoma (OSCC. The detection of CTCs may represent a new diagnostic tool for predicting the occurrence of metastatic disease in OSCC and endow with the treatment strategies to efficiently treat and prevent cancer metastasis. This review gives an insight into the significance of CTCs and different techniques for detection of CTCs.

    Full Text Available Abstract Background Cervical cancer (CC, a leading cause of cancer-related deaths in women worldwide, has been causally linked to genital human papillomavirus (HPV infection. Although a host of genetic alterations have been identified, molecular basis of CC development is still poorly understood. Results We examined the role of promoter hypermethylation, an epigenetic alteration that is associated with the silencing tumor suppressor genes in human cancer, by studying 16 gene promoters in 90 CC cases. We found a high frequency of promoter methylation in CDH1, DAPK, RARB, and HIC1 genes. Correlation of promoter methylation with clinical characteristics and other genetic changes revealed the following: a overall promoter methylation was higher in more advanced stage of the disease, b promoter methylation of RARB and BRCA1 predicted worse prognosis, and c the HIC1 promoter methylation was frequently seen in association with microsatellite instability. Promoter methylation was associated with gene silencing in CC cell lines. Treatment with methylation or histone deacetylation-inhibiting agents resulted in profound reactivation of gene expression. Conclusions These results may have implications in understanding the underlying epigenetic mechanisms in CC development, provide prognostic indicators, and identify important gene targets for treatment.

    Full Text Available Background and Objective: The present study was done to analyze the immunoexpression of diagnostic markers (MIB-1: molecular immunology borstel and PCNA: proliferating cell nuclear antigen in grading cervical intraepithelial lesion (CIN and squamous cell carcinoma (SCC in cervix. Setting and Design: Total 150 cervical biopsies were divided into four groups respectively; Group I-Normal (n = 32, Group II- CIN (n = 60, Group III- SCC (n = 44, Group IV- CA cervix (n = 14 respectively. Materials and Methods: These biopsies were stained with monoclonal antibodies by streptavidin--biotin method. Mean labeling index was calculated and grading was performed using the I--III scoring system. Statistical Analysis: Findings were correlated with age and menopausal status. Statistical analysis was done by using student sample′t′ test and analysis of variance (ANOVA by SPSS 10 package. Results: MIB-1 immunostaining was positive in 112/150 (74.6% cases and PCNA in 118 /150 (78.6% cases. Labeling indices showed linear progression from normal to CIN to SCC to cancer lesion. Few cases of low-grade CIN lesion had high proliferative index. A significant positive correlation was found between age and PCNA and MIB-1 values (P < 0.05 when comparison was made for all the cases. Conclusion: These markers may be useful in identifying low-grade CIN lesion with high proliferative index. These cases should be kept for follow up studies so that proper intervention can be taken at an early stage. This method is simple and cost effective and can easily be done in formaline-fixed paraffin embedded tissues in a clinical laboratory for grading CIN and SCC lesions in cervix.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    Colorectal self-expandable metal stents (SEMS) have been used successfully as preoperative bridges to surgery for obstructive left-sided colorectal carcinoma. Endoscopic relief of the obstruction allows for full bowel preparation and accurate preoperative staging. A laparoscopic approach, considered by many to be contraindicated in the presence of obstruction, becomes feasible after endoscopic decompression. We present a case of obstructive carcinoma of the descending colon successfully treated with endoscopic decompression with colorectal SEMS. Subsequent staging with computed tomography revealed a renal cell carcinoma in the left kidney. Synchronous laparoscopic resection of the two carcinomas was performed, with no morbidity. To the best of our knowledge, this is the first report of endolaparoscopic left hemicolectomy and synchronous laparoscopic radical nephrectomy for obstructive carcinoma of the descending colon and renal cell carcinoma. The advantages of colorectal SEMS and the endolaparoscopic approach in managing obstructive colorectal carcinoma are discussed.

    Basalomatosis is an uncommon skin condition characterized by the occurrence of multiple basal cell carcinomas. Many cases reported in the literature have been attributed to arsenic treatment in psoriasis patients. We report a patient with basalomatosis caused by cobalt-60 ({sup 60}Co) irradiation. A 55-year-old farmer developed 43 basal cell carcinomas 20 years after treatment of an immuno-blastoma with {sup 60}Co irradiation. All the tumours were located within the radiation fields. Other possible causes of basalomatosis, such as arsenic intoxication and basal cell naevus syndrome, were excluded. The patient`s multiple superficial basal cell carcinomas probably represent a late adverse effect of the {sup 60}Co irradiation. (Author).

    Merkel cell carcinoma is believed to be derived from Merkel cells after infection by Merkel cell polyomavirus (MCPyV) and other poorly understood events. Transcriptional profiling using cDNA microarrays was performed on cells from MCPy-negative and MCPy-positive Merkel cell carcinomas and isolated normal Merkel cells. This microarray revealed numerous significantly upregulated genes and some downregulated genes. The extensive list of genes that were identified in these experiments provides a large body of potentially valuable information of Merkel cell carcinoma carcinogenesis and could represent a source of potential targets for cancer therapy.

    Full Text Available Abstract Small cell carcinoma of the bladder (SCCB is rare, highly aggressive and diagnosed mainly at advanced stages. Hematuria is the main symptom of this malignancy. The origin of the disease is unknown; however the multipotent stem cell theory applies best to this case. Histology and immunohistochemistry shows a tumour which is indistinguishable from small cell lung carcinoma (SCLC. Coexistence of SCCB with other types of carcinoma is common. The staging system used is the TNM-staging of bladder transitional cell carcinoma. The treatment is extrapolated from that of SCLC. However, many patients with SCCB undergo radical resection which is rarely performed in SCLC. Patients with surgically resectable disease ( or = cT4bN+M+ should be managed with palliative chemotherapy based on neuroendocrine type regimens comprising a platinum drug (cisplatin in fit patients. The prognosis of the disease is poor mainly in the case of pure small cell carcinoma. Other research programs are needed to improve the outcome of SCCB.

    Stromelysin 3 is a member of the metalloproteinase family, which is expressed in various remodelling processes. The prognosis of breast cancers and squamous cell carcinomas is correlated to the level of expression of this protein. The purpose of the present work was to evaluate the expression of stromelysin 3 in the major types of basal cell carcinomas. We selected cases of primary tumours that were fully excised, without previous biopsy: 40 Pinkus tumors, 40 superficial, 40 nodular, 38 morpheiform basal cell carcinomas and 10 cases showing deep subcutaneous or muscular invasion. Immunohistochemistry was carried out using monoclonal anti-ST3 antibodies (MC Rio, IGBMC Strasbourg), and evaluated on a semi-quantitative scale from 0 to 3. Positively stained cells were restricted to the periphery of the epithelial cells, which, by contrast, never expressed stromelysin 3. The global rate of expression was 27% in Pinkus tumors, 65% in superficial, 72.5% in nodular, 87% in morpheiform and 100% in deeply invasive carcinomas. The rates of tumours showing the highest number of positively stained cells (class 2 or 3) were respectively 7.5%, 20%, 45%, 63% and 100%. This systematic study of stromelysin3 expression in basal cell carcinomas confirms that it is a marker of poor prognosis, because the rate of positive tumours was much higher in aggressive carcinomas. Moreover, the majority of tumours showing an intense expression (i.e. the highest number of positively stained cells in their stroma) were of the morpheiform and deeply invasive types, which are of poor prognosis. Altogether, the studies performed on cutaneous tumours are consistent with the theory of stromelysin 3 playing an active role in tumour progression.

    A 75-year-old-man, with a 2-month history of abdominal pain, underwent a standard diagnostic workup that included a CT scan that showed a large right renal mass and subcentimeter nodes in the right and left lung lobes. In December 2003, the patient underwent right nephrectomy with adrenalectomy and a diagnosis of renal cell carcinoma (pT3N0M0 stage) was made. No further treatment was proposed and patient was followed up regularly. In October 2006, the annual gastrointestinal endoscopy showed asymptomatic multilobulated and polypoid masses in the gastric fundus and gastric body that corresponded to metastasis of the renal carcinoma that had been resected three years ago. Surgical treatment was refused and oral treatment with sunitinib (50 mg/day consecutively for 4 weeks followed by 2 weeks off) was initiated. Patient completed one cycle and development of acute toxicity (grade 3 asthenia, anorexia and mucositis) led to treatment interruption. After recovering from acute toxicity, the patient was proposed to reinitiate treatment with dose reduction, but he refused any medical treatment. At the follow-up visit, three months later, the gastrointestinal endoscopy showed four unspecific 2 mm nodules without malignant evidence. The whole-body CT did not reveal any other abnormality except for the known lung nodes. PET scan six months after treatment confirmed complete gastric response.

    Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-third of the affected population develop oral squamous cell carcinoma. The histopathological diagnosis of verrucous carcinoma is challenging, and the interpretation of early squamous cell carcinoma requires immense experience. Here we present a rare case of a 24-year-old male with OSMF transforming to verrucous carcinoma with invasive squamous cell carcinoma. Even though the case had a straightforward clinical diagnosis, the serial sectioning done for pathological diagnosis disclosed the squamous cell carcinoma.

    2016-01-01

    Trichoepitheliomas (TE) are benign tumours but occasionally can undergo transformation to malignant neoplasms more commonly as Basal Cell Carcinoma (BCC). The correct diagnosis between these tumours is very important because basal cell carcinoma is locally aggressive neoplasm and requires total surgical excision with wide healthy margins while trichoepithelioma needs simple excision. We describe three patients who developed basal cell carcinoma with facial trichoepitheliomas. The only clinical feature that distinguished the carcinomas from the trichoepitheliomas was their larger size, in all three patients, one patient with recurrent, hyper pigmented swelling with surface ulceration and in another patient there are multiple trichoepitheliomas, and other family members are also affected. The history, clinical features and histopathological findings were suggestive of the evolution of basal cell carcinoma directly from trichoepithelioma in our first two cases, but in the third case TE and BCC were separate lesions on face and we are uncertain about whether the BCC developed independently or by transformation from a trichoepithelioma. Based on our clinicopathological observations in the three patients and reports in the recent literature, BCC with follicular differentiation and trichoepithelioma are considered to be highly related.

    Full Text Available PURPOSE: The determination of prognosis in patients with renal cell carcinoma (RCC is based, classically, on stage and histopathological aspects. The metastatic disease develops in one third of patients after surgery, even in localized tumors. There are few options for treating those patients, and even the new target designed drugs have shown low rates of success in controlling disease progression. Few studies used high throughput genomic analysis in renal cell carcinoma for determination of prognosis. This study is focused on the identification of gene expression signatures in tissues of low-risk, high-risk and metastatic RCC clear cell type (RCC-CCT. MATERIALS AND METHODS: We analyzed the expression of approximately 55,000 distinct transcripts using the Whole Genome microarray platform hybridized with RNA extracted from 19 patients submitted to surgery to treat RCC-CCT with different clinical outcomes. They were divided into three groups (1 low risk, characterized by pT1, Fuhrman grade 1 or 2, no microvascular invasion RCC; (2 high risk, pT2-3, Fuhrman grade 3 or 4 with, necrosis and microvascular invasion present and (3 metastatic RCC-CCT. Normal renal tissue was used as control. RESULTS: After comparison of differentially expressed genes among low-risk, high-risk and metastatic groups, we identified a group of common genes characterizing metastatic disease. Among them Interleukin-8 and Heat shock protein 70 were over-expressed in metastasis and validated by real-time polymerase chain reaction. CONCLUSION: These findings can be used as a starting point to generate molecular markers of RCC-CCT as well as a target for the development of innovative therapies.

    AIM: To determine whether cyclooxygenase-2 (COX-2) was expressed in human esophageal squamous cell carcinoma.METHODS: Quantitative reverse transcription-polymerase chain reaction (RT-PCR), western blotting, immunohistochemistry and immunofluorescence were used to assess the expression level of COX-2 in esophageal tissue.RESULTS: COX-2 mRNA levels were increased by >80-fold in esophageal squamous cell carcinoma when compared to adjacent noncancerous tissue. COX-2 protein was present in 21 of 30 cases of esophageal squamous cell carcinoma tissues, but was undetectable in noncancerous tissue. Immunohistochemistry was performed to directly show expression of COX-2 in tumor tissue.CONCLUSION: These results suggest that COX-2 may be an important factor for esophageal cancer and inhibition of COX-2 may be helpful for prevention and possibly treatment of this cancer.

    Full Text Available Basal cell carcinoma is the most common malignant skin tumour. Chronic sun exposure is considered as the main etiologic factor in its development. Although it mainly occurs on sun-exposed areas as the face and neck, it rarely develops on the forearms and/or arms. The etiologic factors which affect the anatomic distribution of basal cell carcinoma are not well-known. Here we report two patients who developed basal cell carcinoma on the forearm. None of the patients had a specific etiologic factor except for chronic sunlight exposure. The aim of our report is to show that this prevalant cutaneous malignancy can be encountered in rare/unusual areas. (Turk J Dermatol 2012; 6: 51-4

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

    Full Text Available Metastasis from various neoplasms to the spleen is very rare and most of the cases are found at autopsy. We report a patient presenting with uterine cervical cancer with splenic metastases. A 49-year-old woman presenting with genital bleeding was referred to our hospital and diagnosed with stage IIB cervical cancer. She underwent concomitant chemoradiotherapy (CCRT consisting of 50 Gy whole pelvis irradiation, high-dose-rate intracavitary brachytherapy 24 Gy/4 fractions and six weeks of paclitaxel and carboplatin administration. Ten months after the initial therapy, CT revealed recurrence at spleen. Although she received 5 courses of nedaplatin, enlargement of the tumor was noticed. She underwent a splenectomy and the result of histology was compatible with metastasis of cervical cancer.

    Mutations in the PTCH gene, the human homolog of the Drosophila patched gene, have been found to lead to the autosomal dominant disorder termed Nevoid Basal Cell Carcinoma Syndrome (NBCCS, also called Gorlin Syndrome). Patients display an array of developmental anomalies and are prone to develop a variety of tumors, with multiple Basal Cell Carcinomas occurring frequently. We provide here the results of molecular testing of a set of Italian Nevoid Basal Cell Carcinoma Syndrome patients. Twelve familial patients belonging to 7 kindreds and 5 unaffected family members, 6 non-familial patients and an additional set of 7 patients with multiple Basal Cell Carcinoma but no other criteria for the disease were examined for mutations in the PTCH gene. All of the Nevoid Basal Cell Carcinoma Syndrome patients were found to carry variants of the PTCH gene. We detected nine novel mutations (1 of which occurring twice): 1 missense mutation (c.1436T>G [p.L479R]), 1 nonsense mutation (c.1138G>T [p.E380X]), 6 frameshift mutations (c.323_324ins2, c.2011_2012dup, c.2535_2536dup, c.2577_2583del, c.3000_3005del, c.3050_3051del), 1 novel splicing variant (c.6552A>T) and 3 mutations that have been previously reported (c.3168+5G>A, c.1526G>T [p.G509V], and c.3499G>A [p.G1167R]). None of the patients with multiple Basal Cell Carcinoma but no other criteria for the syndrome, carried germline coding region mutations.

  1. Are primary renal cell carcinoma and metastases of renal cell carcinoma the same cancer?

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

    Four cases of primary small cell carcinoma of the skin (PSCCS) are presented (ages ranging from 60 to 68 years). Ultrastructurally, two cell types were identified, with both presenting electron-dense secretory granules and paranuclear intermediate filaments. Argyrophylia was positive in one case. Intense solar elastosis in two cases and actinic keratosis in one case suggest a possible role from solar damage in the pathogenesis of this tumor. According to comparative ultrastructural features, different histogenetic possibilities in Merkel cells (MC), peripheral neuroblastic tissue, and totipotential cells are discussed. Some neurosecretory-like granules were observed in basal cell carcinoma (BCC). We consider that PSCCS reproduces cells similar to MC and probably originates in stem cells with totipotential capacity.

    Verrucous epidermal nevi are hamartomatous lesions of the epidermis that, unlike other epidermal nevi (such as sebaceous nevus or nevus comedonicus), are rarely associated with malignant neoplasms. The majority of squamous cell carcinoma develop in linear or multiple epidermal nevus and rarely in solitary epidermal nevus. In general, the prognosis is favorable. We report a case of well-differentiated invasive squamous cell carcinoma arising from a multiple verrucous epidermal nevus. Although there is no consensus on prophylactic removal of epidermal nevus, its removal and biopsy should be considered if changes occur. PMID:28300931

    We describe the case of a 60 year old female smoker who presented with a three month history of weight loss (14 Kg), generalized abdominal discomfort and malaise. Chest radiography demonstrated a mass projected inferior to the hilum of the right lung. Computed Tomography of thorax confirmed a lobulated lesion in the right infrahilar region and subsequent staging abdominal CT demonstrated a low density lesion in the neck of the pancreas. Percutaneous Ultrasound guided pancreatic biopsy was performed, histology of which demonstrated pancreatic tissue containing a highly necrotic small cell undifferentiated carcinoma consistent with metastatic small cell carcinoma of the bronchus.

    We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma. Biopsy results revealed metastatic transitional cell carcinoma of the tibia. Intramedullary nailing was performed which relieved pain on weightbearing. The patient declined radiotherapy and was started on a palliative care regimen. This case illustrates the importance of histological diagnosis in the treatment of diaphyseal lesions.

    Full Text Available Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell carcinoma that exhibited full-thickness perforation of the scapha cartilage. Permanent sections through the eroded cartilage confirmed tumor invasion extending to the posterior ear skin.

    Squamous cell carcinoma of the mammary gland is rare in both veterinary and human medicine. Whereas human metaplastic and squamous variants are known, the objectives of the current study were to ascertain the presence of such entities in canine mammary tumors and to distinguish them from other (epidermal, sweat gland) squamous tumors that may develop in the same area. A panel of antibodies (anti-cytokeratin [CK] 19, CK 14, CK 5/6, pancytokeratin, and vimentin) was used on 18 mammary gland malignancies with squamous features and 16 malignant skin tumors (11 squamous cell carcinomas of the skin and 5 sweat glands). Fifteen of the 18 mammary carcinomas were classified as metaplastic carcinomas, and the remaining 3 were classified as squamous cell carcinomas. The 2 most useful markers to establish the histogenesis of mammary tumors were pancytokeratin and CK 19. All other antibodies were equally expressed (CK 14 and 5/6) in all histotypes. The antibody panel discriminated primary epidermal squamous tumors (pancytokeratin positive and CK 19 negative) from gland-derived squamous neoplasms (pancytokeratin positive and CK 19 positive) but failed to distinguish primary mammary tumors from other squamous tumors of glandular origin.

    Highlights: •Nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest. •Nesfatin-1 enhances HO-8910 cell apoptosis. •Nesfatin-1 inhibits HO-8910 cell proliferation via mTOR and RhoA/ROCK signaling pathway. •The first report of nesfatin-1-mediated proliferation in ovarian epithelial carcinoma. -- Abstract: Nesfatin-1, an 82-amino-acid peptide derived from a 396-amino-acid precursor protein nucleobindin 2 (NUCB2), was originally identified in hypothalamic nuclei involved in the regulation of food intake. It was recently reported that nesfatin-1 is a novel depot specific adipokine preferentially produced by subcutaneous tissue, with obesity- and food deprivation-regulated expression. Although a relation between ovarian cancer mortality and obesity has been previously established, a role of nesfatin-1 in ovarian epithelial carcinoma remains unknown. The aim of the present study is to examine the effect of nesfatin-1 on ovary carcinoma cells proliferation. We found that nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest, this inhibition could be abolished by nesfatin-1 neutralizing antibody. Nesfatin-1 enhances HO-8910 cell apoptosis, activation of mammalian target of rapamycin (mTOR) and RhoA/ROCK signaling pathway block the effects of nesfatin-1-induced apoptosis, therefore reverses the inhibition of HO-8910 cell proliferation by nesfatin-1. In conclusion, the present study demonstrated that nesfatin-1 can inhibit the proliferation in human ovarian epithelial carcinoma cell line HO-8910 cells through inducing apoptosis via mTOR and RhoA/ROCK signaling pathway. This study provides a novel regulatory signaling pathway of nesfatin-1-regulated ovarian epithelial carcinoma growth and may contribute to ovarian cancer prevention and therapy, especially in obese patients.

    Background Squamous cell carcinoma antigen is used as a tumour marker and is routinely measured in clinical laboratories. We validated two different immunoassays and found three cases in which the squamous cell carcinoma antigen concentrations deviated greatly between the two immunoassays. Here, we aimed to elucidate the mechanisms responsible for these deviations. Methods The squamous cell carcinoma antigen concentrations were determined using the ARCHITECT SCC (CLIA method) and the ST AIA-PACK SCC (FEIA method). We performed polyethylene glycol precipitation and size exclusion chromatography to assess the molecular weight and spike recovery and absorption tests to examine the presence of an autoantibody. Results Both methods exhibited good performances for the measurement of squamous cell carcinoma antigen, although a correlation test showed large differences in the squamous cell carcinoma antigen concentrations measured using the two methods in three cases. The results of polyethylene glycol treatment and size exclusion chromatography indicated the existence of a large molecular weight squamous cell carcinoma antigen in these three cases. The spike recovery tests suggested the possible presence of an autoantibody against squamous cell carcinoma antigen. Moreover, the absorption test revealed that large squamous cell carcinoma antigen complexes were formed by the association of squamous cell carcinoma antigen with IgG in two cases and with both IgG and IgA in one case. Conclusions This study describes the existence of large molecular weight squamous cell carcinoma antigen that has complexed with immunoglobulin in the serum samples. The reason for the deviations between the two immunoassays might be due to differences of their reactivities against the squamous cell carcinoma antigen immune complexes with their autoantibody. To our knowledge, this is the first report to describe the coupling of squamous cell carcinoma antigen with IgA.

    OBJECTIVE To investigate the histogenesis and biological characteristics and factors influencing prognosis of small cell carcinoma of the esophagus(ESCC).METHODS The expression of CK, NSE, Syn, CHr-A and CD56 proteins were detected immunohistochemically in 63 cases of small cell carcinoma of the esophagus.RESULTS The ESCC cases were divided into two groups as follows: a puresmall cell group (28/63) and compound small cell group (35/63). Theimmunohistochemistry results were positive for: CK in 41.3%, NSE in 36.5%,Syn in 90.5%, CHr-A in 60.3% and CD56 in 50.8%. The difference betweenstaining of the pure small cell carcinoma and compound small cellcarcinoma was not statistically significant. The size and depth of tumorinvasion, the positive residual incision edge and lymph node metastasiswere the major factors influencing long-term survival.CONCLUSION Small cell carcinoma of the esophagus is a highly malignanttumor, which expresses neuroendocrine antigens. The histophathologicorigin is still unknown but the non-neuroepithelial origin was accepted in thisstudy.

    Objective: To investigate the effect of Celecoxib on proliferation and apoptosis of the endometrial carcinoma cell HEC-1B and the effect on the expression of Fas and Survivin mRNA. Methods: The inhibition on the growth of human endometrial carcinoma cell HEC-1B was investigated by cell culture and MTT experiment when treated with different concentrations of Celecoxib. The cell apoptosis was detected by flow cytometry and DNA Ladder Electrophoresis. The change of the expression of Fas and Survivin mRNA after the treatment of Celecoxib was detected With RT-PCR. Results: Celecoxib could effectively inhibit the growth of HEC-1B cells and induce apoptosis. Survivin mRNA expression was decreased and Fas mRNA expression was increased after treating with Celecoxib. Conclusion: Celecoxib could inhibit HEC-1B cell proliferation and induce its apoptosis.

  7. Concomitant Small Cell Neuroendocrine Carcinoma of Gallbladder and Breast Cancer

    Directory of Open Access Journals (Sweden)

    Paolo Aiello

    2014-01-01

    Full Text Available The neuroendocrine carcinoma is defined as a high-grade malignant neuroendocrine neoplasm arising from enterochromaffin cells, usually disposed in the mucosa of gastric and respiratory tracts. The localization in the gallbladder is rare. Knowledge of these gallbladder tumors is limited and based on isolated case reports. We describe a case of an incidental finding of small cell neuroendocrine carcinoma of the gallbladder, observed after cholecystectomy for cholelithiasis, in a 55-year-old female, who already underwent quadrantectomy and sentinel lymph-node biopsy for breast cancer. The patient underwent radiotherapy for breast cancer and six cycles of chemotherapy with cisplatin and etoposide. Eighteen months after surgery, the patient was free from disease. Small cell neuroendocrine carcinoma of the gallbladder has poor prognosis. Because of the rarity of the reported cases, specific prognostic factors have not been identified. The coexistence of small cell neuroendocrine carcinoma of the gallbladder with another malignancy has been reported only once. The contemporary presence of the two neoplasms could reflect that bioactive agents secreted by carcinoid can promote phenotypic changes in susceptible cells and induce neoplastic transformation.

Methods: To analyse of the information, we used frequency distributions with absolute values as well as percentages, measures of central tendency as well as of variance. The relation ship between cualitative variables was done by means of a chi square statistical test. A p value less or equal to 0.05, was significant. The cumulative survival probability was done using the Kaplan-Meier method. The comparison between the survival times was done using a logarithmic range test. The level of significance was again fixed at less or equal to 0.05. Results: A total of 778 cases were studied at the end of the study period, 91 patients had died. The 5 year, cumulative survival probability for the whole population was 88.3%. The patients in which carcinoma in situ was detected at the time of diagnosis, showed a cumulative survival probability of 98.8% while those with invasive carcinoma had a value of 68.3%. This difference was statistically significant. The cumulative survival probability for the patients diagnosed with squamous cell carcinoma was 89% while those with adenocarcinoma had a value of 80%. This difference did not fall within the range of statistical significance, though. Conclusions: If we compare our results with similar investigations done elsewhere, we can see that our values are superior to those seen in countries

    Lactate dehydrogenase C is an isoenzyme of lactate dehydrogenase and a member of the cancer-testis antigens family. In this study, we aimed to investigate the expression and functional role of lactate dehydrogenase C and its basic mechanisms in renal cell carcinoma. First, a total of 133 cases of renal cell carcinoma samples were analysed in a tissue microarray, and Kaplan-Meier survival curve analyses were performed to investigate the correlation between lactate dehydrogenase C expression and renal cell carcinoma progression. Lactate dehydrogenase C protein levels and messenger RNA levels were significantly upregulated in renal cell carcinoma tissues, and the patients with positive lactate dehydrogenase C expression had a shorter progression-free survival, indicating the oncogenic role of lactate dehydrogenase C in renal cell carcinoma. In addition, further cytological experiments demonstrated that lactate dehydrogenase C could prompt renal cell carcinoma cells to produce lactate, and increase metastatic and invasive potential of renal cell carcinoma cells. Furthermore, lactate dehydrogenase C could induce the epithelial-mesenchymal transition process and matrix metalloproteinase-9 expression. In summary, these findings showed lactate dehydrogenase C was associated with poor prognosis in renal cell carcinoma and played a pivotal role in the migration and invasion of renal cell carcinoma cells. Lactate dehydrogenase C may act as a novel biomarker for renal cell carcinoma progression and a potential therapeutic target for the treatment of renal cell carcinoma.

  10. Effect of chaetocin on renal cell carcinoma cells and cytokine-induced killer cells

    Directory of Open Access Journals (Sweden)

    Rombo, Roman

    2016-04-01

    Full Text Available We examined the cytotoxic effects of chaetocin on clear cell renal cell carcinoma (ccRCC cells and the possibility to combine the effects of chaetocin with the effects of cytokine-induced killer cells (CIK assayed by MTT assay and FACS analysis. Chaetocin is a thiodioxopiperazine produced by fungi belonging to the chaetomiaceae family. In 2007, it was first reported that chaetocin shows potent and selectiveanti-cancer activity by inducing reactive oxygen species. CIK cells are generated from CD3+/CD56- T lymphocytes with double negative phenotype that are isolated from human blood. The addition of distinct interleukins and antibodies results in the generation of CIK cells that are able to specifically target and destroy renal carcinoma cells. The results of this research state that the anti-ccRCC activity of chaetocin is weak and does not show a high grade of selectivity on clear cell renal cell carcinoma cells. Although the CIK cells show a high grade of selective anti-ccRCC activity, this effect could not be improved by the addition of chaetocin. So chaetocin seems to be no suitable agent for specific targeting ccRCC cells or for the combination therapy with CIK cells in renal cancer.

  12. Hepatocellular Carcinoma with Foamy Histiocyte-Like Appearance: A Deceptively Clear Cell Carcinoma Appearing Variant

    Directory of Open Access Journals (Sweden)

    Takuji Noro

    2010-08-01

    Full Text Available Hepatocellular carcinoma (HCC shows many pathological features, and it varies architecturally and cytologically. There have been many reports and discussions of the morphological features of HCC. A 63-year-old man was found to have a solitary tumor in liver segment 7 that was diagnosed as HCC. A partial resection of liver segment 7 was performed. Microscopically, the tumor lesion showed a moderately differentiated HCC. There was also a lesion with foamy histiocyte-like cells corresponding to the white lesion in the face of the cut tumor. Immunohistochemical staining showed that they were negative for CD68, S-100, vimentin, and HMB-45. The cytoplasm itself was negative on periodic acid Schiff (PAS and Sudan staining. Without immunohistological analysis, it is difficult to distinguish this HCC variant from clear cell carcinoma or metastases of renal cell carcinoma. It is important to recognize this type as a specific cytological variant of HCC that requires confirmation by immunohistochemistry. This report describes the case of a patient with a morphologically distinctive pattern of HCC with prominent cell cytoplasm that had a foamy histiocyte-like appearance. To the best of our knowledge, this is the first report of this HCC variant.

  18. Male Pelvic Squamous Cell Carcinoma of Unknown Primary Origin

    Directory of Open Access Journals (Sweden)

    Lauren Chiec

    2014-01-01

    Full Text Available Pelvic squamous cell carcinoma of unknown primary origin has been described in several case reports of female patients. However, there have been no published reports describing male patients with pelvic squamous cell cancer of unknown primary origin. Our case describes a 52-year-old man who presented with right buttock pain, rectal urgency, and constipation. His physical examination demonstrated tenderness to palpation around his gluteal folds. Computed tomography scan of his abdomen and pelvis demonstrated a large mass in his retroperitoneum. The mass was determined to be squamous cell carcinoma of unknown primary origin. Additionally, the patient had small nodules in his right lower lung lobe and right hepatic lobe. The patient was treated with concomitant chemoradiation, including cisplatin and intensity-modulated radiation therapy, followed by carboplatin and paclitaxel. The patient achieved partial remission, in which he remained one year after his presentation. Our case is consistent with the literature which suggests that squamous cell carcinoma of unknown primary origin occurring outside of the head and neck region may have a more favorable prognosis than other carcinomas of unknown primary origin. Further studies are necessary to determine the most appropriate work-up, diagnosis, and optimal treatment strategies.

    Xanthohumol is one of the main flavonoids in hop extracts and in beer. Very few investigations of xanthohumol have studied hepatocellular carcinoma. In this study, the inhibitory effects of xanthohumol on human hepatocellular carcinoma cell lines were investigated. The IC(50) values of xanthohumol for two hepatocellular carcinoma cell lines and one normal hepatocyte cell line were 108, 166 and 211 microm, respectively. Normal murine hepatocyte cell line had more resistance to xanthohumol than hepatocellular carcinoma cell lines. Besides, the inhibitory effects of xanthohumol on human hepatocellular carcinoma cell lines were attributed to apoptosis as indicated in the results of flow cytometry, fluorescent nuclear staining and electrophoresis of oligonucleosomal DNA fragments. Hop xanthohumol was more efficient in the growth inhibition of hepatocellular carcinoma cell lines than the flavonoids silibinin and naringin from thistle and citrus. It was shown for the first time that xanthohumol from hops effectively inhibits proliferation of human hepatocellular carcinoma cells in vitro.

    Glucose transporters, such as GLUT-1, mediate the important mechanisms involved in cellular glucose influx, allowing cells to proliferate and survive. The significance of GLUT-1 expression in oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC) has been less explored, and no study has investigated it in relation to verrucous carcinoma (VC). We evaluated 30 cases each of OED, OSCC, and VC, graded further on the basis of their differentiation, immunohistochemically for GLUT-1 expression, along with 10 specimens of normal oral mucosa (NOM) as controls. In OSCC, GLUT-1 expression increased with the degree of dysplasia and increasing grade (P GLUT-1 expression in OSCC along with the degree of dysplasia and the histologic grade reflects the expanding glycolytic response to hypoxia. This is the first study to have revealed prominent GLUT-1 expression in VC, highlighting its inherent metabolic capacity.

    Enterovesical fistulas are not uncommon in patients with inflammatory or malignant colonic disease, however,fistulas secondary to primary bladder carcinomas are extremely rare. We herein reported a patient presenting with intractable urinary tract infection due to enterovesical fistula formation caused by a squamous cell carcinoma of the urinary bladder. This patient underwent en bloc resection of the bladder dome and involved ileum, and recovered uneventfully without urinary complaint. To the best of our knowledge, this is the first case reported in the literature.

    Enterovesical fistulas are a well-known complication of inflammatory and malignant bowel disease. Bladder carcinoma, however, is an extremely rare etiology. We describe a case of squamous cell carcinoma of the bladder with an enterovesical fistula. This rare phenomenon has never been previously reported in western literature. We review the diagnosis, work up and treatment of enterovesical fistulas. Unfortunately, the prognosis for these highly invasive tumors is very poor and the treatment is often palliative. The high morbidity and mortality makes management of these patients exceptionally challenging.

    AIM: To elucidate the distinctive pathobiological behavior between signet ring cell carcinoma (SRC) and mucinous adenocarcinoma of the stomach.METHODS: Based on the histological growth patterns and cell-functional differentiation classifications of stomach carcinoma, we conducted a series of comparative studies.All paraffin-embedded and frozen blocks were collected from the files of Cancer Institute of China Medical University. On the basis of histopathological observation, we applied enzymatic and mucous histochemistry, immunohistochemistry,flow cytometry (FCM) and molecular biology to compare these two categories of gastric cancers in terms of the DNA ploidy, proliferative kinetics, the expression of gastric carcinoma associated gene product and instabilities of mitochondrial DNA (mtDNA).RESULTS: Gastric SRC was commonly seen in females below 45 years, mostly presenting diffuse growth and ovary or uterine cervix metastasis. The majority of SRC were absorptive and mucus-producing functional differentiation type (AMlPFDT), which growth relied on estrogen. Meanwhile,stomach mucinous adenocarcinomas were mostly observed in males over 50 years, prone to massive growth or nest growth and extensive peritoneal infiltration, showing two categories of cell-functional differentiation types: AMPFDT and mucus-secreting functional differentiation type (MSFDT).Expressions of ER, enzyme c-PDE and 67kDaLN-R in SRC were evidently higher than that in mucinous adenocarcinoma,while expressions of LN, CN-IV, CD44v6, and PTEN protein were obviously lower in SRC than that in mucinous adenocarcinoma (P<0.05). There was no statistic significance in VEGF, ECD and instabilities of mtDNA (P>0.05) between the above two gastric carcinomas.CONCLUSION: Though SRC and mucinous adenocarcinoma were both characterized by abundant mucus-secretion, they were quite different in morphology, ultrastructure, cellfunctional differentiation and protein expression, indicating different mechanisms of

    Full Text Available Malignancy in pregnancy is rare. Carcinomas in pregnancy are mostly kidney cell mass. Renal cell carcinoma (RCC is the commonest malignancy in pregnancy. Because of softness and increased vascularity, rupture of renal cell carcinoma is not uncommon. Here we are presenting a rare case of renal cell carcinoma in pregnancy with spontaneous rupture resulting in massive hemoperitoneum and serious outcome because of late presentation renal cell carcinoma seldom ruptures. A 26 year old woman G2P1L1 with term pregnancy was referred to hospital 80kms away from periphery with non-progression of labour. There was antenatal record suggesting hypertensive disorder of pregnancy in second trimester. On examination, patient was in hypovolemic shock with profuse distension of abdomen. Diagnosis of abruption grade 3 or rupture uterus was made and immediate laparotomy was done. On opening the abdomen, there was hemoperitoneum but uterus was intact. Emergency LSCS done extracted a stillborn baby. There were no retro placental clots also. There was lot of necrotic tissue in the abdomen and there was a tumour arising from lower pole of left kidney which had invaded the renal vessels and had ruptured. Peripartum hysterectomy and left nephrectomy was done. Women did not respond to treatment and died. The objective of presenting this case is the dilemmas faced by the obstetrician in case of shock in 2nd stage of labour. Simple diagnostic tool like renal ultrasound will help to detect at an early stage which could improve the outcome. All cases of hypertensive disorders of pregnancy should be investigated for secondary causes of hypertension. Abdominal USG must be done for all cases of hypertensive disorders of pregnancy in 2nd trimester. Prompt diagnosis and early treatment is the key in management of such condition in pregnancy.

    Nasopharyngeal carcinoma (NPC) is a malignancy with remarkable ethnic and geographic distribution in southern China and Southeast Asia. Alternative to genetic changes, aberrant epigenetic events disrupt multiple genes involved in cell signaling pathways through DNA methylation of promoter CpG islands and/ or histone modifications. These epigenetic alterations grant cell growth advantage and contribute to the initiation and progression of NPC. In this review, we summariye the epigenetic deregulation of cell signaling in NPC tumorigenesis and highlight the importance of identifying epigenetic cell signaling regulators in NPC research. Developing pharmacologic strategies to reverse the epigenetic-silencing of cell signaling regulators might thus be useful to NPC prevention and therapy.

    Full Text Available Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the dermatology clinic with a painless raised nodule on his left forearm arising in a tattooed area. A biopsy of the lesion revealed a poorly differentiated squamous cell carcinoma infiltrating into a tattoo. The lesion was completely excised and the patient remains disease-free one year later. Conclusion. All previous reports of squamous cell carcinomas arising in tattoos have been well-differentiated low-grade type or keratoacanthoma-type and are considered to be coincidental rather than related to any carcinogenic effect of the tattoo pigments. Tattoo-associated poorly differentiated invasive carcinoma appears to be extremely rare.

    Background Mounting evidence suggests that tumors are histologically heterogeneous and are maintained by a small population of tumor cells termed cancer stem cells. CD133 has been identified as a candidate marker of cancer stem cells in laryngeal carcinoma. This study aimed to analyze the chemoresistance of CD133+ cancer stem cells.Methods The response of Hep-2 cells to different chemotherapeutic agents was investigated and the expression of CD133 was studied. Fluorescence-activated cell sorting analysis was used to identify CD133,and the CD133+ subset of cells was separated and analyzed in colony formation assays,cell invasion assays,chemotherapy resistance studies,and analyzed for the expression of the drug resistance gene ABCG2.Results About 1%-2% of Hep-2 cells were CD133+ cells,and the CD133+ proportion was enriched by chemotherapy.CD133+ cancer stem cells exhibited higher potential for clonogenicity and invasion,and were more resistant to chemotherapy. This resistance was correlated with higher expression of ABCG2.Conclusions This study suggested that CD133+ cancer stem cells are more resistant to chemotherapy. The expression of ABCG2 could be partially responsible for this. Targeting this small population of CD133+ cancer stem cells could be a strategy to develop more effective treatments for laryngeal carcinoma.

    In this study, we aimed at evaluating the distribution of HPV types and the expression of P53 and Ki-67 in cervix carcinomas of Mozambican women. Fourty-seven invasive carcinomas, 10 CIN III, and 10 normal cervix were studied. P53 and Ki-67 expression was examined immunohistochemically. HPV infection and HPV types were detected by PCR (GP5+/bio-GP6+) and enzyme-immunoassay, respectively. Expression of P53 and Ki-67 and detection of HPV were as follows: normal cervix--0%, 10%, and 0%, respectively; CIN III--10%, 0%, and 100%, respectively; invasive carcinomas--50%, 55.5%, and 70%, respectively. HPV 16 was identified in 54% of invasive carcinomas, HPV 31, 33, 35, and 45 in 23%, "unidentified" HPV in 19%, and HPV 18 in 4% of invasive carcinomas. No significant associations were observed between P53 expression, Ki-67 expression, and HPV infection. In conclusion, we observed a high frequency of HPV infection in CIN III lesions and invasive carcinomas from Mozambican women, with HPV 16 representing the most frequent viral type. HPV status was not related to P53 and Ki-67 expression. Both P53 and Ki-67 are associated with invasive cervix carcinomas, mainly of the squamous keratinizing histotype.

    Full Text Available Sarcoma of the prostate and sarcomatoid carcinoma of the prostate are rareconditions, both characterized by a poor prognosis. Sarcomatoid carcinoma ofthe prostate typically arises from the evolution of an underlying adenocarcinoma,occasionally featuring heterologous elements, bulky disease being possiblebut rare. In contrast, sarcoma of the prostate derives from non-epithelialmesenchymal components of the prostatic stroma, shows rapid growth, andfrequently presents as massive pelvic tumors obstructing the urinary tractat the time of diagnosis. We report the case of a 55-year-old patient with atwo-month history of symptoms of urinary obstruction. The patient presentedwith an extremely enlarged heterogeneous prostate, although his prostatespecificantigen level was low. The lack of a history of prostatic neoplasia ledus to suspect sarcoma, and a transrectal prostate biopsy was carried out. Animmunohistochemical study of the biopsy specimen did not confirm the clinicalsuspicion. However, in view of the clinical features, we believe that sarcoma ofthe prostate was the most likely diagnosis. The patient received neoadjuvantchemotherapy followed by radiation therapy. At this writing, surgical resectionhad yet to be scheduled.

    Myoepithelial cells have important physical and paracrine roles in breast tissue development, maintenance, and tumor suppression. Recent molecular and immunohistochemical studies have demonstrated phenotypic alterations in ductal carcinoma in situ-associated myoepithelial cells. Although the relationship of lobular carcinoma in situ (LCIS) and myoepithelial cells was described in 1980, further characterization of LCIS-associated myoepithelial cells is lacking. We stained 27 breast specimens harboring abundant LCIS with antibodies to smooth muscle myosin heavy chain, smooth muscle actin, and calponin. Dual stains for E-cadherin/smooth muscle myosin heavy chain and CK7/p63 were also performed. In each case, the intensity and distribution of staining in LCIS-associated myoepithelial cells were compared with normal breast tissue on the same slide. In 78% of the cases, LCIS-associated myoepithelial cells demonstrated decreased staining intensity for one or more myoepithelial markers. The normal localization of myoepithelial cells (flat against the basement membrane, pattern N) was seen in 96% of LCIS, yet 85% of cases had areas with myoepithelial cell cytoplasm oriented perpendicular to the basement membrane (pattern P), and in 30% of cases, myoepithelial cells appeared focally admixed with LCIS cells (pattern C). This study characterizes detailed architectural and immunophenotypic alterations of LCIS-associated myoepithelial cells. The finding of variably diminished staining favors application of several myoepithelial immunostains in clinical practice. The interaction of LCIS with myoepithelial cells, especially in light of the perpendicular and central architectural arrangements, deserves further mechanistic investigation.

    Full Text Available Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

    Full Text Available INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16 by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC, six cases were Keratinized Squamous Cell Carcinoma (KSCC and four cases were Adenocarcinoma (ADC. Immunohistochemistry study showed positivity in eleven cases (55%; seven cases (35% were non-keratinized squamous cell carcinoma; three cases (15% were keratinized squamous cell carcinoma and one case (5% belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC. The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinomas

    T lymphocytes can mediate the destruction of cancer cells by virtue of their ability to recognize tumor-derived antigenic peptides that are presented on the cell surface in complex with HLA molecules and expand. Thus, the presence of clonally expanded T cells within neoplastic lesions...... is an indication of ongoing HLA-restricted T cell-mediated immune responses. Multiple tumors, including renal cell carcinomas (RCCs), are often infiltrated by significant amounts of T cells, the so-called tumor-infiltrating lymphocytes (TILs). In the present study, we analyzed RCC lesions (n = 13) for the presence...... of expanded T-cell clonotypes using T-cell receptor clonotype mapping. Surprisingly, we found that RCCs comprise relatively low numbers of distinct expanded T-cell clonotypes as compared with melanoma lesions. The numbers of different T-cell clonotypes detected among RCC-infiltrating lymphocytes were...

  16. Pancreatic Stellate Cells and Pancreatic Carcinoma: An Unholy Alliance

    2009-07-01

    Full Text Available The importance of the stromal compartment in the development, proliferation, invasion, metastasis and resistance of epithelial cancers has increasingly been recognized in recent decades [1, 2]. This stromal reaction is found in many carcinomas, e.g. in breast, prostate, colon, ovarian and pancreatic cancer. It is made up of stromal cells, endothelial cells, immune cells and extracellular matrix proteins. Moreover, the ECM proteins in the stroma act as a reservoir for growth factors released either by tumor or stromal cells, thus enabling autocrine and paracrine stimulation of the cells within the tumor mass. In this respect, groundbreaking work in solid tumors was done by Mina Bissell with breast carcinoma as her model system [3]. Recently, Vonlaufen et al. have contributed a review on the relationship between activated pancreatic stellate cells (PSCs and pancreatic ductal adenocarcinoma cells which is worth reading [4]. Vonlaufen et al., with their own study [5] and those of some other groups (see their review, convincingly demonstrate a reciprocal influence of both nonepithelial and epithelial constituents of pancreatic carcinoma which works to their mutual benefit. Thus, the coinjection of PSC and pancreatic tumor cells enhances tumor growth and metastasis. In In vitro and animal models, PSCs increase tumor cell proliferation and decrease basal and induced apoptosis of pancreatic tumor cells. On the other hand, pancreatic tumor cells activate PSCs, recruit them to their vicinity and stimulate their proliferation. This review clearly exemplifies the specialized milieu in which both cell types grow to their mutual benefit, thus forming one of the deadliest tumors we know.

    Acanthosis nigricans (AN), an entity recognized since the 19th century, is a dermatopathy associated with insulin-resistant conditions, endocrinopathies, drugs, chromosome abnormalities and neoplasia. The latter, also known as malignant AN, is mostly related to abdominal neoplasms. Malignant AN occurs frequently among elderly patients. In these cases, the onset is subtle, and spreading involves the flexural regions of the body, particularly the axillae, palms, soles, and mucosa. Gastric adenocarcinoma is the most frequent associated neoplasia, but many others have been reported. Renal cell carcinoma (RCC), although already reported, is rarely associated with malignant AN. The authors report the case of a woman who was being treated for depression but presented a long-standing and marked weight loss, followed by darkening of the neck and the axillary regions. Physical examination disclosed a tumoral mass in the left flank and symmetrical, pigmented, velvety, verrucous plaques on both axillae, which is classical for AN. The diagnostic work-up disclosed a huge renal mass, which was resected and further diagnosed as a RCC. The post-operative period was uneventful and the skin alteration was evanescent at the first follow-up consultation. The authors call attention to the association of AN with RCC. PMID:27284539

    Renal endocrine tumours are extremely rare, and carcinoid tumoral elements in renal cell carcinoma have never been reported. This is the first report of a composite renal cell carcinoma containing a clear cell renal cell carcinoma associated with carcinoid tumoral elements, in a patient with synchronous metastatic disease. In the absence of specific radiological and clinical manifestations, typical morphological features as well as an immunostaining profile of neuroendocrine differentiation were identified by microscopy. Secondary nodal and liver localisations were characterised by carcinoid elements only. Despite antiangiogenic therapy, liver metastasis progressed, suggesting that adjuvant therapy cannot be based on the presence of the clear cell renal cell carcinoma component. In this context, extensive tissue sampling is recommended to reveal the endocrine component that is the most aggressive element of such a composite carcinoma.

  20. Selective assembly of laminin variants by human carcinoma cells

    BACKGROUND: The laminins are heterotrimeric basement membrane glycoproteins. Eight subunits that can be assembled into laminins have been characterized and are known as: A, B1, B2, S, M, K, B2t, B1k laminin chains. Although many neoplastic cells secrete laminins and some of them even assemble...... basement membranes, the pattern of production of various laminin subunits remains to be explored. EXPERIMENTAL DESIGN: The expression of laminin was examined in several human carcinoma cells using a panel of specific cDNA probes as well as polyclonal and chain specific monoclonal antibodies....... For this purpose a human laminin S chain 2 kb cDNA was isolated and characterized and used together with existing probes for laminin chains. RESULTS: All carcinoma cell lines had a high level of expression of three light chains (B1, S and B2) mRNA. In contrast, the heavy chains of laminin, A and M, were expressed...
