Aqp1 Expression

Background. Mutations of the β-catenin gene (CTNNB1), leading to aberrant immunohistochemical expression of β-catenin, represent a key mechanism of WNT/β-catenin pathway alteration in ovarian cancer. Aquaporin 1 (AQP1), as component of transmembrane-water-channel family proteins, has been documented in different human tumors and, recently, also in ovarian carcinoma. Only few studies have investigated the pathogenetic and prognostic role of β-catenin and AQP1 in ovarian carcinoma. Methods. We evaluated the expression of β-catenin and AQP1 in the preoperative peritoneal biopsies of 32 patients with peritoneal carcinosis, in which a histological diagnosis of high grade serous ovarian carcinoma was made. Furthermore, we have investigated their potential association with chemotherapeutic response evaluated at the omental site, as well as with clinico-pathological parameters. Results. Sixteen cases showed an aberrant membranous and cytoplasmic β-catenin staining pattern. The remaining 16 cases showed a preserved β-catenin expression localized only in cell membranes; 20 cases showed positive membranous staining (AQP1+), while 12 cases were considered negative (AQP1–). In the AQP+ group, we detected a significant association of AQP1 expression with poor chemotherapy response in omental tissues complete response score (CRS) 1-2, while a CRS 3 was never observed in all positive cases. Conclusions. Our findings suggest that β-catenin and AQP1 are expressed in a sub-group of ovarian tumors and play important roles in carcinogenesis. Patients affected by high grade serous carcinoma could be categorized in two different predictive groups: as AQP+ and AQP–. AQP+ cases may represent a subset of poor responders who could be considered more eligible for cytoreductive surgery rather than for neoadjuvant chemotherapy.

Primary Origin

A 62-year-old woman presented with unilateral inguinal lymphadenopathy, existing for several months. As it was initially thought to be lymphoma, the lymph node was resected. Pathology, however, revealed a metastasis of a high-grade papillary serous cancer, according to its stainings, most likely ovarian in origin. Further staging showed lymphadenopathies in the inguinofemoral, para-aortic and mediastinal regions. Consequently, the multidisciplinary oncologic meeting advised a diagnostic laparoscopy which showed no macroscopic spread within the abdomen. Pathological examination of biopsies as well as both ovaries showed no sign of ovarian cancer. The patient received standard chemotherapy, that is, carbo-Taxol-Avastin, to which she showed complete response after three cycles as shown on positron emission tomography–CT. A review of existing literature showed that this is a very unusual case of high-grade serous carcinoma, where no site of origin could be found.

Abstract The objective of the present study was to perform a quantitative analysis of cancer stem cell (CSC) marker expression in ovarian carcinoma effusions. The clinical role of SSEA1 in metastatic high-grade serous carcinoma (HGSC) was additionally analyzed. CD133, Nanog, SOX2, Oct3/4, SSEA1, and SSEA4 protein expressions were quantitatively analyzed using flow cytometry (FCM) in 24 effusions. SSEA1 expression by immunohistochemistry was analyzed in 384 HGSC effusions. Highly variable expression of CSC markers by FCM was observed, ranging from 0 to 78% of Ber-EP4-positive cells in the case of CD133, with the largest number of negative specimens seen for SSEA4. SSEA1 expression by immunohistochemistry was found in HGSC cells in 336/384 (89%) effusions, most commonly focally (< 5% of cells). SSEA1 was overexpressed in post-chemotherapy disease recurrence specimens compared with chemo-naïve HGSC effusions tapped at diagnosis (p = 0.029). In univariate survival analysis, higher SSEA1 expression was significantly associated with poor overall survival (p = 0.047) and progression-free survival (p = 0.018), though it failed to retain its prognostic role in Cox multivariate survival analysis in which it was analyzed with clinical parameters (p = 0.059 and p = 0.111 for overall and progression-free survival, respectively). In conclusion, CSC markers are variably expressed in ovarian carcinoma effusions. SSEA1 expression is associated with disease progression and poor survival in metastatic HGSC. Silencing this molecule may have therapeutic relevance in this cancer.

Introduction: The ovaries are the primary female reproductive organs and endocrine glands. Ovarian carcinoma has often been called as the silent killer because the symptoms may develop so late that the chances of cure are very poor. According to World Health Organisation (WHO) ovarian tumours are classified based upon their most probable tissue of origin: surface epithelial (65%), germ cell (15%), sex cord-stromal (10%), metastases (5%) and miscellaneous. The malignant surface epithelial tumours are further classified by cell type into serous, mucinous, endometrioid, clear cell, brenner, seromucinous and undifferentiated carcinoma. The most widely used tumour marker in ovarian carcinoma is CA-125 which is considered as gold standard. Aim : To find the utility of serum CA-125 levels in histopathological variants of malignant surface epithelial tumours, degree of differentiation and their distribution according to clinical data pertaining to age, parity, history of use of oral contraceptive pills/ovulation inducing drugs and family history of carcinoma ovary/breast or colon. Materials and Methods: A prospective study (cohort study) was done at Guru Gobind Singh Medical College and Hospital, Faridkot over a period of 1.5 year (April 2017-oct 2018) on 50 ovarian masses which were diagnosed as ovarian carcinoma. Data was represented as frequencies and percentages for categorical variables and as means and standard deviations for continuous variables. Analysis was done using Statistical Package for Social Sciences (SPSS) v 20.0.0. Results: Serous carcinoma (80%) topped among all the histological variants. Serous high grade carcinoma was more common than serous low grade carcinoma. Maximum rise of serum CA-125 levels were seen in serous carcinoma. Among serous carcinomas, mean serum CA-125 levels were more in high grade serous carcinoma than low grade serous carcinoma and the results were statistically significant. conclusion: Serum CA-125 level is a great tool for diagnosis, follow-up and prognosis of ovarian carcinomas.
