ABSTRACT
The high incidence and fatality rate of recurrent ovarian cancer (ROC) have always been the clinical problem. For part of patients with platinum-sensitive recurrent ovarian cancer, the secondary cytoreductive surgery (SCS) followed by platinum-based combination chemotherapy can prolong their survival time and improve quality of life. Therefore, it's a critical matter to accurately identify the patients who will benefit from surgery treatment. Several predictive models have been proposed for the selection of the patients for SCS. This article summarizes the research progress in the surgical treatment of platinum-sensitive recurrent ovarian cancer in recent years.
ABSTRACT
Background: Rechallenge of a platinum-based chemotherapy is the most common approach for a recurrent platinumsensitive epithelial carcinoma ovary. However, this carries a substantial risk of cumulative neurotoxicity. Objectives: In the present study, we tried to compare the efficacy and toxicities of gemcitabine pegylated liposomal doxorubicin combination regimen to rechallenge of paclitaxel-carboplatin in this setting. Materials and Methods: A total of 30 patients were included in the study. The patients were randomized into two groups each containing 15 patients. The study group received injection gemcitabine at the dose of 1 g/m2 injection intravenously on day 1 and day 8 and liposomal doxorubicin 30 mg/m2 on day 1 in a 3 weekly cycle up to a total of six cycles in absence of disease progression or unacceptable toxicities. The control group patients were treated with injection paclitaxel at a dose of 175 mg/m2 I/V infusion and injection carboplatin at a dose considering area under the curve 6 in a 3 weekly for six cycles. Results: In the study arm, out of 14 patients, 4 (28.57%) patients had complete response, 6 (42.85%) had partial response, 3 (21.42%) had stable disease, and 1 (7.14%) showed disease progression. In the control arm, 6 (40%) patients out of 15 showed complete response, and 4 (26.66%) partial response. Disease progression was noted in 1 (6.66%) patient. There was less incidence of neurotoxicity compared to the control arm. Conclusion: Chemotherapy with a combination of gemcitabine and pegylated liposomal doxorubicin shows equivalent efficacy in platinum-sensitive recurrent ovarian cancer when compared to rechallenge of platinum-based chemotherapy. The regimen has an acceptable toxicity profile with lesser incidence of neuropathy than rechallenge of paclitaxel-carboplatin combination.
