Objective: To evaluate the prognostic factors for stage III ovarian epithelial carcinoma so as to provide scientific basis for further reasonable therapy.
Methods: The clinical records of 369 patients with stage III ovarian epithelial carcinoma, aged 53 +/- 9 (22-77), were reviewed retrospectively. SPSS 10.0 was utilized to analyze the possible prognostic factors statistically.
Results: All patients received cytoreductive surgery, 289 cases (71.8%) of which achieved optimal cytoreduction. During the operation, 150 cases (41.8%) and 265 cases (71.8%) were found with intestinal and diaphragmatic involvement respectively. Pathologic results showed that serous type was the most common histological type (48.9%) and mucinous type was the least one (2.2%). The grades G1, G2, and G3 accounted for 1.7%, 42.7%, and 55.6% respectively. 290 cases with effective response to surgery underwent chemotherapy for 3-22 (10 +/- 4) courses. Recurrence was recorded in 190 cases (51.5%) and death was recorded in 152 cases (41.2%). Multivariate analysis revealed that intestinal involvement, diaphragmatic invasion, tumor residuals, and course number of chemotherapy were significantly correlated with prognosis (P < 0.01, < 0.05, < 0.01, and < 0.01 respectively).
Conclusion: Cytoreduction for the tumor in peritoneal cavity and positive chemotherapy should be emphasized sufficiently and may be helpful for the prognosis of stage III ovarian epithelial carcinoma.
