ABSTRACT
BACKGROUND:
Around 15% of metastatic endometrial carcinoma (EC) are MMRd/MSI-H improving response to immune checkpoint inhibitors (ICI). So far, few data existed considering the chemotherapy (CT) sensitivity in MMRd/MSI-H EC, especially response to first-line platinum-based treatment. PATIENTS ANDMETHODS:
We performed a multicentric retrospective analysis reporting the response to first line platinum CT in MMRd/MSI-H EC patients. The primary endpoints were objective response rate (ORR) and progression-free survival (PFS) with first line platinum-based CT.RESULTS:
A total of 112 patients MMRd/MSI-H EC from 8 centers were identified. Median overall survival was 58.0 months (95% CI 45.3-95.1). Among them, 78 patients received first line platinum CT in recurrent/metastatic setting. With a median follow up of 32.6 months (min 0.03; max 135.0), ORR and DCR (disease control rate) were 50% (95% CI 38.5-61.5) and 68% (95% CI 56.4-78.1), respectively. Median PFS and OS from first line platinum-based CT was 7.8 months (95% CI 6.0-9.0) and 51.9 months (95% CI 28.0-NE), respectively. Median PFS with ICI in second line (n = 48) was 10.7 months (95% CI 3.4-NE) from ICI initiation.CONCLUSION:
ORR in first line metastatic MMRd/MSI-H EC is consistent with efficacy in an all comer metastatic EC population.Palavras-chave
