Survival outcomes for patients with high-grade serous ovarian carcinoma may be better when interval debulking surgery is performed within a month of neoadjuvant chemotherapy (NACT).
Why This Matters
Interval debulking surgery following NACT has gained ground in the treatment of high-grade serous ovarian carcinoma.
But whether there is an optimal time interval between the last dose of NACT and interval debulking surgery for patients with high-grade serous ovarian carcinoma remains unclear.
The current study demonstrated that performing interval debulking surgery within 4 weeks of NACT may be associated with significantly better overall survival.
The team reviewed survival outcomes for 115 women with stage IIIC/IV high-grade serous ovarian carcinoma who received NACT before undergoing interval debulking.
The authors correlated survival outcomes with the timing of surgery.
Median progression-free survival was 26.6 months for women who had surgery within a month of NACT, vs 14.4 months for women who had surgery later (P = .004).
Median overall survival was 66.3 months among patients who had surgery within a month of NACT completion, vs 39.4 months for those who had surgery later (P = .002).
On multivariate analysis, surgery within a month of NACT was an independent predictor of both progression-free survival (hazard ratio [HR], tylenol 750 para que sirve 2.33) and overall survival (HR, 3.23).
The results appeared to be independent of tumor biology, given that patients with BRCA1/2 mutations were distributed equally between the groups.
This was a retrospective, single-institution study with a relatively small number of participants.
BRCA1/2 testing was not standard practice at the start of the study period and was not included in the multivariate analysis.
No external funding for the study was reported.
Several authors reported ties to pharmaceutical companies, including Roche, AstraZeneca, and Merck.
