Recently, considerable attention has been focused on the role of the small heat-shock protein group hsp27, hsp70 and hsp90 in the clinical outcome of several malignancies. However, conflicting data exist regarding the prognostic role of hsp27 expression in ovarian carcinoma, and the prognostic significance of hsp70 and hsp90 expression still remains unknown in these tumours. The purpose of this study was to investigate immunohistochemically whether hsp27, hsp70 and hsp90 expression was associated with clinicopathological parameters and survival in 52 epithelial ovarian carcinomas. Chi-square test, Kaplan-Meier and Cox regression analysis were used for statistical analysis. Among clinicopathological parameters, hsp27, hsp70 and hsp90 expression was only correlated with FIGO stage; hsp70 and hsp90 positivity failed to detect survival. However, the overall survival rate of patients with hsp27 expression was 13%, which was significantly worse than that of patients without hsp27 expression (47%) (p<0.01). The prognosis was also adversely affected by FIGO stage (p<0.01) and presence of ascites (p<0.01). In multivariate analysis, hsp27 expression and FIGO stage were independent prognostic variables. Our results indicate that hsp70 and hsp90 expression had no prognostic relevance in epithelial ovarian carcinomas. However, hsp27 expression and FIGO stage in these tumours could be reliable indicators of prognosis.

PurposeThe purpose of this study is to evaluate the prognostic role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) and the need for para-aortic lymphadectomy in patients with primary fallopian tube carcinoma (PFTC).Materials and MethodsNinety-one patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of six academic centers. Clinicopathological, surgical, and complete blood count data were collected.ResultsIn univariate analysis, advanced stage, suboptimal surgery, and NLR > 2.7 were significant prognostic factors for progression-free survival, whereas in multivariate analysis, only advanced stage and suboptimal surgery were significant. In addition, in univariate analysis, cancer antigen 125 ≥ 35 U/mL, ascites, advanced stage, suboptimal surgery, NLR > 2.7, PLR > 233.3, platelet count ≥ 400,000 cells/mm3, staging type, and histological subtype were significant prognostic factors for overall survival (OS); however, in multivariate analysis, only advanced stage, suboptimal surgery, NLR > 2.7, and staging type were significant. Inclusion of pelvic and para-aortic lymphadenectomy in surgery showed significant association with longer OS, with a mean and median OS of 42.0 months and 35.5 months (range, 22 to 78 months), respectively, vs. 33.5 months and 27.5 months (range, 14 to 76 months), respectively, for patients who underwent surgery without para-aortic lymphadenectomy (hazard ratio, 3.1; 95% confidence interval, 1.4 to 5.7; p=0.002).ConclusionNLR (in both univariate and multivariate analysis) and PLR (only in univariate analysis) were prognostic factors in PFTC. NLR and PLR are inexpensive and easy tests to perform. In addition, patients with PFTC who underwent bilateral pelvic and para-aortic lymphadenectomy had longer OS.

Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) products have been implicated in the regulation of immune system, tumor cell apoptosis, and angiogenesis in many human tumors. In this study, we investigated the expression of COX-2 and iNOS in ovarian carcinomas by immunohistochemistry and correlated the results with other prognostic parameters. Specimens from 100 ovarian carcinomas were studied by immunohistochemistry for COX-2 and iNOS expression, and angiogenesis microvessel density (MVD) was evaluated by CD34-stained microvessels. High COX-2 expression was observed in 85% of carcinomas. No correlation was found between COX-2 expression and clinicopathologic variables. Patients with high COX-2-expressed tumors had shorter overall survival, but it is not statistically significant. Expression of iNOS in serous and low-grade carcinomas was significantly higher than that in nonserous and high-grade carcinomas (P < 0.05). There was a positive correlation between COX-2 and iNOS expression (P= 0.009). No correlation of COX-2 and iNOS expression with MVD was found. Expression of iNOS showed no effect on survival of the patients. We found that iNOS expression might act in the first steps of carcinogenesis, whereas COX-2 expression was seen in more advanced tumors. Shorter overall survival of patients with high COX-2 expression might indicate new targets for therapy.

Conservative management of early-stage EC in women of reproductive age using oral progestins was effective and did not compromise oncological outcome. Pregnancy in the study patients was achieved spontaneously and artificially.
