Structured Abstract Objective: Analysis of nodal pelvic and paraaortal findings in patients operated on for ovarian cancer. Design: Retrospective study. Setting: Department of Obstetrics and Gynecology, First Faculty of Medicine, Charles University, Prague. Methods: Analysis of a series of 30 patients - assesment of median age, staging, grading, histologi- cal findings, percentage of pelvic and paraaortic nodal involvement, median number of lympho- nodes. Results: Median age of the series was 54 years, 15 patients had an early ovarian cancer and 15 patients advanced ovarian cancer. Paraaortal lymphadenectomy revealed metastatic involvement of lymphonodes in 8/30 cases (26,7%) and pelvic lymphadenectomy in 4/18 cases (22,7%). Involve- ment of any lymphonodes had 9 patients (30%). In a group of patients with early ovarian cancer no case had a nodal involvement, in a group of advanced ovarian cancer 9/15 (60%) patients were positive. Median numbers of removed pelvic and paraaortal lymphonodes were 8,3 resp. 5,4 nodes. Conclusion: Pelvic and paraaortal lymphadenectomy in ovarian cancer have especially a staging importance with adequate therapeutic consequencies. Currently a sampling extent of operation is preferred to systematic lymphadenectomy. It is recommended to concentrate operations to onco- gynecological centers.
