Background: Epithelial cancers are the most common ovarian malignancy accounting for 90% of all type of ovarian cancer. Objective of this study was to evaluate the surgical morbidity and to study clinical outcomes of 3 cycles versus 6 cycles of neoadjuvant chemotherapy.Methods: A total 30 women with diagnosis of advanced epithelial ovarian cancer were randomly divided equally to receive either 3 cycles (Group 1) or 6 cycles (Group 2) of neoadjuvant chemotherapy. End points noted were duration of surgery, extent of surgery, perioperative complications and length of stay.Results: Both groups had comparable demographic profile. Surgery was more difficult in early IDS group with lesser percentage of patients achieving minimum intended surgery in early IDS (61.53% versus 80. 47%) peri-operative complications were seen more commonly in early IDS group compared to late IDS group (26.66% versus 69.2%). However mean duration of surgery was similar in both groups. Mean duration of stay in hospital was 5.4 days in late IDS group and 7.6 days in early IDS group. The mean follow-up period in late IDS was 7 months and in early IDS was 5 months. Survival in both groups when patients were followed up till the end of study period (12 months) was similar (p=0.186).Conclusions: Authors conclude that late IDS may be used as a treatment option in the high-risk group of patients. Though there was no significant difference at 6 months follow up, higher percent of women were disease free in late IDS
