Comparison of the Efficacy and Safety of Nivolumab Plus Cabozantinib versus Sunitinib in the Treatment of Elderly Patients with Advanced Clear Cell Renal Cell Carcinoma.

Objective: Advanced clear cell renal cell carcinoma (ccRCC) seriously affects the life and health of patients, but effective treatment for this disease is still lacking in clinic. This study investigated the efficacy of nivolumab plus cabozantinib versus sunitinib in the treatment of elderly patients with advanced ccRCC.

Methods: The clinical data of 216 elderly patients with advanced ccRCC in our hospital from January 2020 to January 2022 were retrospectively analysed. On the basis of different treatment regimens, patients were divided into the cabozantinib group (n = 111, receiving nivolumab and cabozantinib) and the sunitinib group (n = 105, receiving nivolumab and sunitinib). The overall survival time, disease control rates, health status, incidence of adverse events and identification of prognostic risk were compared between the two groups.

Results: The cabozantinib group had higher overall survival time, disease control rate and scores in the Functional Assessment of Cancer Therapy-Kidney Symptom Index and EuroQol-Five Dimensions-Three Levels Questionnaire than the sunitinib group. The incidence of adverse events in the cabozantinib group was lower than that in the sunitinib group (p < 0.001). However, no difference existed in the identification of prognostic risk between the two groups (p > 0.05).

Conclusions: The effect of nivolumab plus cabozantinib on the treatment of elderly patients with advanced ccRCC is better than that of nivolumab plus sunitinib, with fewer adverse reactions and higher safety. However, the research results require further clinical studies to confirm and promote.
