Background: The primary objective of this study is to assess Qol & response rates in platinum resistant ovarian cancer patients with peritoneal metastasis treated with PIPAC procedure in comparison with conventional systemic intravenous chemotherapy. Methods: Between October 2017 and December 2019, 31 PIPAC applications were done in 15 patients with cisplatin 10.5mg/m2 and doxorubicin 2.1mg/m2. During same period 20 patients received systemic chemotherapy with clinician’s choice of drug ((mono-therapy consisting of pegylated liposomal doxorubicin or topotecan or gemcitabine or paclitaxel weekly with or without bevacizumab).The response rate (With MRI & Ca-125) & quality of life assessment (QLQ C-30) of both the group was done periodically and recorded. Results: Overall 35 patients were analysed in this study. The results have been presented in Table. Conclusions: PIPAC in comparison to intravenous chemotherapy for platinum resistant ovarian cancer with peritoneal metastasis showed better response rates (66.6 vs. 22.4%) and improved quality of life score. PIPAC has shown promising results and should be in the arsenal of the clinicians managing patients with platinum resistant ovarian cancer.
