First-line chemotherapy analysis on survival in carcinoma ovary patients: Data from a Northern Indian cancer center

Aims: This study aims to assess the survival and identify the prognostic factors in ovarian cancer patients treated with surgery and carboplatin/paclitaxel based first-line chemotherapy (CT). Settings and Design: The electronic medical records of all ovarian cancer patients registered during January 2009 and December 2017 were screened retrospectively. Subjects and Methods: A total of 440 cases were included in accordance with the inclusion/exclusion criteria of study. The comprehensive data regarding demography, treatment, chemotoxicities, recurrence, and others were collated and analyzed. Statistical Analysis Used: Cox regression analysis was used for univariate and multivariate analyses of prognostic factors. Results: The median age at diagnosis was 50.6 years. All cases had got CT-related morbidity but no associated mortality. The median recurrence-free survival (RFS) and mean overall survival (OS) were 30 (95% confidence interval [CI]: 24.65-35.38) months and 40.4 months, respectively. A significant difference was observed among the RFS ( P < 0.001); and OS ( P = 0.036) in relation to the stage of disease. Furthermore, patients who relapsed post first-line CT had 36%, 9%, 3% recurrence in second-, third-, and fourth-line CT regimens, respectively. Multivariate analysis proved the histology, low-grade serous, to be the favorable prognostic factor for RFS (hazard ratio = 0.18; 95% CI: 0.04-0.82). Conclusions: Surgery and first-line CT with carboplatin/paclitaxel lead-to-moderate long-term survival in ovarian cancer. The likelihood of relapse is fairly high as stage advances. Low-grade serous histology is an independent prognostic factor for RFS.
