Abstract
Background: Lenvatinib plus pembrolizumab (LP) therapy has emerged as an effective treatment for patients with advanced or recurrent endometrial cancer. However, limited data are available regarding its outcomes in real-world settings. This study aimed to identify prognostic factors associated with the efficacy of LP therapy.
Methods: This multicenter observational study was conducted across 15 institutions in Japan and examined patients with endometrial cancer, including uterine carcinosarcoma, who experienced disease progression after receiving at least one platinum-based chemotherapy, including adjuvant treatment, and subsequently received LP therapy. The prognostic factors for progression-free survival were assessed using a multivariate Cox proportional hazards model.
Results: A total of 105 patients met the inclusion criteria. Improved progression-free survival was independently associated with performance status of 0 (adjusted hazard ratio [aHR] 0.42, 95% confidence interval [CI] 0.23-0.75), platinum-free interval (PFI) of ≥ 6 months (aHR 0.46, 95% CI 0.28-0.78), histology of grade 1-2 endometrioid carcinoma (aHR 0.52, 95% CI 0.30-0.91), and relative dose intensity during the initial 8 weeks (8w-RDI) of lenvatinib of ≥ 50% (aHR 0.53, 95% CI 0.31-0.91). Patients with PFI of ≥ 6 months also demonstrated improved overall survival (HR 0.44, 95% CI 0.25-0.76) and objective response rate (44.0% versus 20.0%, P = 0.011) compared with those with PFI of < 6 months. Additionally, 8w-RDI of lenvatinib ≥ 50% was associated with improved overall survival (HR 0.53, 95% CI 0.30-0.92) compared to those with < 50%.
Conclusions: This study identified several novel prognostic factors for LP therapy. Among them, PFI may inform treatment selection for recurrent endometrial cancer following chemotherapy.

期刊介绍:
The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
