Efficacy and safety of combined anlotinib-oral etoposide treatment for patients with platinum-resistant ovarian cancer

Objective: Despite the availability of numerous treatment options, managing patients with platinum-resistant ovarian cancer (PROC) remains challenging, and the prognosis of PROC is notably unfavorable. This retrospective study aimed to assess the efficacy and safety of combined anlotinib-oral etoposide treatment for patients with PROC. Methods: Data of 23 patients who were diagnosed with PROC from January 2020 to November 2022 and treated with anlotinib combined with oral etoposide for at least 2 cycles were retrospectively analyzed. Results: Among per-protocol patients, 9 (45.0%; 95% confidence interval [CI]=21.1-68.9) of 20 patients achieved partial response and 17 (85.0%, 95% CI=67.9-100.0) of 20 patients achieved disease control. The median progression-free survival was 8.7 months (95% CI=5.3-11.6). The incidence of adverse events (any grade) was 100%, and the incidence of grade 3-4 adverse events was 54.5%. Conclusion: Anlotinib combined with etoposide emerged effective for the treatment of PROC.
