Abstract 322P
Background
There is limited evidence regarding the prognostic value of the three-tier chemotherapy response score (CRS) in advanced epithelial ovarian cancer (EOC). We aimed to evaluate the impact of CRS on survival in advanced EOC.
Methods
This prospective single-centre study included consecutive women with stage IIIC-IV EOC who underwent interval debulking surgery (IDS) after neoadjuvant chemotherapy (NACT) at Tata Medical Center between March 2021 and June 2022. Clinical characteristics, progression-free survival (PFS), and overall survival (OS) were compared between the CRS groups.
Results
Among the 102 women treated with NACT followed by IDS, CRS 1 was found in 16 (15.7%), CRS 2 in 66 (64.7%), and CRS 3 in 20 (19.6%). Age, stage, and BRCA status were not different across CRS groups. The patients with CRS 3 had significantly longer PFS than the other CRS groups (median PFS 17 months, 19.8 months, and not reached for CRS 1, 2, and 3, respectively, P = 0.001). Estimated OS was also significantly longer in those with CRS 3 (median OS 22.2 months, 33 months, and not reached for CRS 1, 2, and 3, respectively, P = 0.035). The PFS and OS differences remained statistically significant in univariate and multivariate analyses.
Conclusions
Chemotherapy response score 3 was associated with improved survival in advanced EOC treated with NACT. The prognostic value of CRS can be used in future studies of response-adapted adjuvant or maintenance treatment in advanced EOC.
