Neoadjuvant chemotherapy followed by interval debulking surgery (IDS) is an alternative treatment option, compared to the current standard of care primary debulking surgery for treating advanced epithelial ovarian cancer (EOC). We present our institute experience of neoadjuvant chemotherapy strategy in the management of EOC which is one of the largest single institute experience.
This is a retrospective analysis of patients with epithelial ovarian cancer who were treated in our institute between 2000 and 2006. Patient with advanced disease by clinical and imaging were treated with 3 cycles of neoadjuvant chemotherapy and then taken up for interval debulking surgery (IDS) who had static or partial or complete response to chemotherapy. The remaining chemotherapy is delivered after the surgery. Patient who had limited disease had primary debulking surgery and then adjuvant chemotherapy according to institute protocol. Outcomes in terms of disease free and overall survival were analysed.
This retrospective analysis included 59 patients with limited disease who had primary debulking surgery and 283 patients with advanced disease who received neoadjuvant chemotherapy. The median age was 50 years and majority are in the 50-59 years age group. Age more than 60 years represent 14.5%. Postmenopausal women were55.3 % and premenopausal women were 44.7 %. Multiparity is higher 70.2% than the uniparity 16.4% ornulliparity 11.7%. Abdomen distension 42% and pain 25 % are the most common symptoms. Advanced stage was the most common presentation 71% with stage III-56.1% and stage IV-14.9%. Among the neoadjuvant chemotherapy group 126/283(44.5%) had optimal cytoreduction, 44/283 (15.5%) had suboptimal cytoreduction and 113/283 (40%) not suitable for IDS. The 5 year disease free and overall survival was 30.8% and 41.5% in the NACT group with advanced disease and 58.5% and 75.8% in the primary cytoreduction group who had limited diseaserespectively. The 5 years overall survival among the IDS group with optimal cytoreduction was 57.1% and 11.7% for the suboptimal cytoreduction group. The 5 years survival was not affected by the number of neoadjuvant chemotherapy cycles delivered before surgery in the IDS group. Patient who received paclitaxol + carboplatin as first line chemotherapy had better survival than carboplatin alone or cyclophosphamide + cisplatin.
NACT as an alternative option to primary debulking surgery in operable EOC is still debatable. But for patient with high disease burden where optimal cytoreduction is not possible NACT strategy is a valid option. Recent randomised controlled trials from Europe had shown the noninferiority of neoadjuvant chemotherapy followed by IDS when compared to the primary debulking surgery in operable advanced EOC.
