Abstract
Ovarian cancer is a leading cause of death from gynecological cancer in the world and in India. This study aims to evaluate the efficacy and toxicity profile of oral metronomic chemotherapy (MCT) in the form of etoposide, cyclophosphamide, and tamoxifen in recurrent and metastatic ovarian cancer. This was a retrospective observational study that included those post-treatment patients who had the recurrent or metastatic disease after completion of treatment in 2018 at Regional Cancer Centre, Bikaner, Rajasthan. Forty patients who were unfit for further intensive intravenous chemotherapy were included. The oral MCT constituted etoposide, cyclophosphamide, and tamoxifen. Descriptive statistics and Kaplan-Meier analyses were performed. Progression-free survival (PFS) and overall survival (OS) were assessed. Forty women with a median age of 62 (range: 35-80) years were enrolled in the study to receive oral MCT. The Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) was 0-1 in 28 patients and 2-3 in 12 patients. The best clinical response rate post-oral MCT was seen in the first 4 months. Objective response was observed in 24 (60%) of patients in the form of stable disease (19, 47.5%) and partial response (5, 12.5%). Disease progression was observed in 10 (25%) of patients. The median follow-up was 6.4 months (4.5-9.2 months). The median estimated OS was 6.5 months. The median estimated PFS was 3.7 months. Nineteen (47.5%) patients had grade-I/II mucositis. Grade-III/IV mucositis were observed in 9 (22.5%) patients. Thirty-seven (92.5%) patients died at the end of the study at 1 year. Dose reduction was required in 15 (37.5%) patients. Oral MCT was found to be an effective and well-tolerated regime with good symptomatic control and low-moderate toxicity profile in patients with relapsed and metastatic ovarian cancer. However, 22% of patients showed grade-III/IV thrombocytopenia.
