Surufatinib combined camrelizumab as a valuable third-line rescue therapy for a patient with extensive-stage for small-cell lung cancer: a case report and literature review.

Abstract

Lung cancer is one of the most common malignant tumors with the highest incidence. Gene mutations are rare in small-cell lung carcinoma (SCLC), resulting in targeted therapy being only a third-line recommendation. Surufatinib (Sulanda) is an oral angio-immune kinase inhibitor used to treat solid tumors. We report a case of SCLC treated with surufatinib combined with camrelizumab, with good therapeutic results in our department. The patient experienced over 18 months of progression-free survival and over 28 months of overall survival. This suggests that surufatinib combined with camrelizumab is an effective third-line treatment for SCLC patients. However, the response rate to surufatinib treatment in all patients with SCLC remains unknown and needs to be determined in a large population.
