Abstract
Little is known about the safety of chemotherapy plus atezolizumab for patients with extensive-stage small cell lung cancer (ES-SCLC) undergoing haemodialysis (HD). An 80-year-old male received carboplatin [area under the concentration-time curve (AUC) = 5 on day 1], etoposide (40 mg/m(2) on days 1, 2, and 3), and atezolizumab (1200 mg/body on day 1) as the first-line therapy for ES-SCLC. He was undergoing HD thrice a week for seven years. HD was provided 16 h after carboplatin administration. During the first cycle, grade 4 neutropenia (neutrophil count: 74/μL) and leukopenia (white blood cell count: 680/μL) occurred. Therefore, chemotherapy was administered with a reduced dose of carboplatin (AUC = 4) and etoposide (30 mg/m(2)) from the second to fourth cycles. After four cycles, no severe non-haematological adverse events occurred, showing a remarkable response. We conclude that the carboplatin, etoposide, and atezolizumab combination can be safely administered to cancer patients undergoing HD.
