Objectives: Ovarian cancer is associated with the highest mortality of gynecologic cancers. Epidemiological and genetic factors of ovarian cancer development are clearly defined but prognostic factors have not been adequately identified. Right and left ovarian cancers seem to act different behaviors at high-grade serous ovarian cancer (HGSOC) prognosis. The aim of this study is to explain this prognostic role of its sidedness. Material and methods: We reviewed 160 consecutive patients with Figo stage 1-3 HGSOCs and undergone surgery at two high-volume hospitals. Prognostic effects of primary tumor location onset were evaluated in terms of 5-year disease free survival and overall survival rate. Results: One hundred-sixty patients with ovarian cancer records were analyzed using the Kaplan-Meier method, that demonstrated a significant difference in the 5-year disease-free survival rates between right and left-sided cancers for all stages (44.6% vs 78.5%, p < 0.001). Also, there was significant difference in the 5-year overall survival rates between the two groups (71.1% vs 91.9%, p = 0.020). Conclusions: Tumor location within the HGSOC seems to be a compelling prognostic factor ovarian cancer. Further prospective studies are needed in order to support our hypothesis.
