Abstract
Ovarian cancer is second prevalent cancer among gynecologic malignancies and the most common type of ovarian cancer is epithelial form (85-90 percent). To detect the risk factors for the epithelial ovarian cancer, a case-control study was conducted in Valieasr hospital in 1988. In this study, 118 cases with epithelial ovarian cancer (according histological records) and 240 controls without any gynecological cancer in gynecologic clinic had been interviewed. For data analysis, T-test, Chi2 test and logistic regression have been used at a =0.05 as level of significance. The mean age in cases was 50±13 and in controls was 49.9±12 years, without significant different. The mean number of pregnancies and parity in cases was less than controls, significantly (P<0.03). The mean months of breast feeding in cases was less than controls (54.9±71.2 versus 82.4±62.7) (P<0.001). The cases had a lower mean age of menarch than controls (P=0.03). 58 percent of cases and 21.3 percent of controls hadn't used any contraception methods (P=0.00001). The mean years of contraception was significantly less in cases versus controls (P<0.001). The odds ratio for epithelial ovarian cancer was 0.24 (95 percent CI: 0.13-0.48) in OCP users, 0.47 (95 percent CI: 0.005-0.43) in TL method, and was 0.41 (95 percent CI: 0.22-0.76) in other contraception methods, relative to women who hadn't used any contraception methods. This study reveals that epithelial ovarian cancer risk increases significantly with earlier menarch, decreasing number of pregnancy, deliveries duration of breast feeding and use of contraception methods. Use of contraception pill and tubal ligation method decreases risk of epithelial ovarian cancer.

Abstract
Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity.
Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference.
Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting.
Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.
