Novel strategy for comprehensive therapy with sustainably complete response in a patient with limited-stage small cell lung cancer: a case report

Small cell lung cancer (SCLC) is an aggressive neuroendocrine tumor with the poorest prognosis among all types of lung cancer. Developing an effective comprehensive strategy remains a key focus. We herein present the first documented case of a 68-year-old man with limited-stage SCLC who has maintained a complete response (CR) for over 30 months to date. CR was achieved with first-line chemotherapy using etoposide and carboplatin combined with chest volumetric-modulated arc therapy. Maintenance therapy with anlotinib extended the progression-free survival to 20 months after first-line therapy. When resistance developed, second-line therapy with albumin-bound paclitaxel, carboplatin, and the immune checkpoint inhibitor durvalumab sustained CR for 7 months. Third-line therapy with etoposide and cisplatin combined with durvalumab has maintained CR to date.Small cell lung cancer (SCLC) is an aggressive neuroendocrine tumor with the poorest prognosis among all types of lung cancer.
