A retrospective study of anlotinib in patients with cervical cancer after chemoradiotherapy.

e17509 Background: Anlotinib is a novel small molecule antiangiogenic drug, which can inhibit multiple tyrosine kinase receptor activity. Its antitumor activity has been proved in various cancers, including gynecological tumors. This retrospective study explored the efficacy and safety of anlotinib monotherapy or anlotinib combined chemotherapy in cervical cancer patients who have disease progressed or metastasis after chemoradiotherapy. Methods: 28 patients with cervical cancer admitted to the Second Affiliated Hospital of Zhengzhou University were enrolled. These patients who had received radiotherapy and at least one line chemotherapy had tumor progression or metastasis. 13 patients received anlotinib monotherapy (12mg/d from day 1 to day 14 in a 21-day cycle) and 15 patients received chemotherapy combined with the anlotinib. Treatment was continued until disease progression or death or intolerable adverse events. The primary endpoint was the objective response rate (ORR), and the secondary endpoints were disease control rate (DCR), progression-free survival (PFS) and safety. Results: As of Dec 31 2020, no one was lost follow up. 2 patients were still under treatment, and 26 patients were evaluable. 1 CR, 6 PR, 13 SD, 6 PD, yielding the ORR of 26.92%, and the DCR of 76.92%. The median PFS for receiving anlotinib monotherapy was 4.57 (95% CI, 3.85-5.29) months, and 8.47 (95% CI, 5.09-11.85) months for combination group. The most common adverse events (AEs)were grade 1, including hypertension (46.43%), anemia (42.85%) and fatigue (39.29%). Grade 3 AEs were hypertension(10.71%) and anemia(7.14%). No higher grade AEs occurred. Conclusions: Anlotinib is safe and effective for patients with advanced cervical cancer after chemoradiotherapy, and it is well tolerated.
