A Retrospective Cohort Study Evaluates Clinical Value of Anlotinib in Persistent, Metastatic, or Recurrent Cervical Cancer After Failure of First-Line Therapy.

Abstract

BackgroundAnlotinib is an oral anti-angiogenesis inhibitor targeting vascular endothelial growth factor receptors (VEGFRs), platelet-derived growth factor receptors, fibroblast growth factor receptors, etc., and its clinical value in cervical cancer is rarely reported. We designed a retrospective study to evaluate the efficacy and safety of anlotinib in patients with persistent, metastatic, or recurrent cervical cancer who have failed first-line therapy, and compare the efficacy of anlotinib with that of apatinib which targets only VEGFR2 and has shown efficacy in recent studies.MethodsFifty-two patients with persistent, metastatic, or recurrent cervical cancer who failed first-line therapy and administrated anlotinib or apatinib as monotherapy or combination with chemo-, radio- or immunotherapy were included in this study. Among the 52 patients, 20 patients who received anlotinib from January 2019 to August 2020 were defined as anlotinib group, whereas 32 patients who received apatinib from our previous study were selected as apatinib group. The safety, objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were reviewed and recorded.ResultsThe ORR and DCR in patients receiving anlotinib were 25% and 80%, respectively. The median PFS and OS in anlotinib group were significantly longer than those in apatinib group, respectively (PFS: 5 months vs 3 months, p=0.015; OS: 10 months vs 5 months, p=0.008). Moreover, the patients treated with anlotinib had better survival with a significantly lower cumulative incidence of cancer-related death than those treated with apatinib (HR=0.31, 95% CI: 0.13–0.77, p=0.012). The most common adverse effects in the patients treated with anlotinib were hypertension (20%), fatigue (20%), and nausea (15%). No drug-related death occurred.ConclusionAnlotinib showed beneficial efficacy and safety and can be a treatment option for patients with persistent, metastatic, or recurrent cervical cancer who have failed the first-line therapy.
