Objective: To assess the relationship between Aquaporin-1 (AQP1) expression and clinicopathological variables in serous epithelial ovarian cancer (EOC). Material and Methods:Serous EOC cases treated in our institution between January 2007 and December 2009 were included in the study. A semi-quantitative immunohistochemical method was used to determine AQP1 expression levels, intratumoral microvessel density (IMD) and AQP1/IMD ratios. The relationship between these parameters and clinicopathological variables were assessed. P values less than 0.05 was considered statistically significant. Results:A total of 55 cases of serous EOC were included in the study.AQP1 was strongly expressed in the membranes of microvessels and small vessels within all tumor tissues. In a few cases, AQP1 expression was also observed in the membrane of interstitial cells and in individual tumor cells. A positive correlation was detected between preoperative CA125 levels and the expression of AQP1 (R: 0.277, p<0.05). AQP1 expression was similar between FIGO stage I-II and FIGO stage III-IV cases (p > 0.05). A significant relationship did not exist between AQP1 expression and FIGO stage, lymph node metastasis or ascites volume (p>0.05). Conclusion:In this study, AQP1 expression did not have a significant association with important clinicopathological variables in serous EOC. Future studies are needed to determine AQP1 expression in other histological types of EOC.

Gereç ve Original Investigation 130 IntroductionEpithelial ovarian cancer (EOC) is the most lethal gynecologic cancer, with a five-year overall survival of approximately 31 to 53%, considering all stages (1-3). Generally accepted clinicopathological variables that may have an impact on survival are tumor histology, disease stage, patient age, performance status of the patient, presence of ascites, residual tumor burden after surgery and preoperative CA-125 level (4-16).Aquaporins are a group of homologous water channel proteins, which are expressed in various tissues (17-19). Aquaporin-1 (AQP1) has important functions in various organs such as the kidney, central and peripheral nervous system, eye, lacrimal glands, salivary glands, lungs, pleura, gastrointestinal system, female and male reproductive system, inner ear and skin. Considering its function in angiogenesis, the possible role of AQP1 in carcinogenesis, tumor progression and metastasis ability has been an area of interest (20,21 A previous study has demonstrated that there is a strong positive correlation between AQP1 expression and intratumoral microvessel density (IMD) in EOC (22). In the present study, we evaluated AQP1 expression in serous EOC, in order to determine its association with...
Objective: To report our experience treating adnexal masses concomitant appendectomy or cholecystectomy using of the Single-Incision Laparoscopic Surgery (SILS). Methods: Nine women with symptomatic and persistent adnexal masses with appendicitis or cholecystitis are included to study. Removal of adnexal masses and performed appendectomy or cholecystectomy via single-incision laparoscopic surgery using a combination of the SILSTM port and straight non-roticulating laparoscopic instruments. Results: 6 patients had symptomatic complex adnexial masses and 3 patients had symptomatic myoma uteri. In 2 of the patients had myoma uteri appendectomy (hysterectomy+bso+appendectomy) were performed concomitantly and in 1 of patients had myoma uteri cholecystectomy (hysterectomy+BSO +cholecystectomy) were performed concomitatly. In 4 of the patients had symptomatic adnexal masses appendectomy (hysterectomy+bso or uso or cystectomy+appendectomy) were performed concomitantly and in 2 of patients had complex adnexial masses cholecystectomy (hysterectomy+USO or USO+cholecystectomy) were performed concomitatly. Mean duration of surgery was 128 min. None of the patients converted to laparotomy. All patients were discharged on postoperative d 1. None of the patients required readmission to hospital. Post-surgery all patients reported that they were satisfied with their incision and cosmetic results. Conclusion: SILS can result in better aesthetic result than conventional laparoscopy for the treatment of adnexal masses concomitant appendectomy or cholecystectomy.
