Current Surgical Perspective on the Prognosis of Small-Cell Lung Cancer

Small-cell lung cancer (SCLC) is a highly aggressive neuroendocrine tumour that can metastasise early, may show resistance to systemic treatment, and has a poor prognosis. The use of tobacco products is closely related to the duration of their use, and approximately 95% of those diagnosed have a history of smoking. No satisfactory progress has been made in the prognosis with current treatment methods up to the present day. The treatment approach has traditionally involved long-term chemotherapy (CT) and radiotherapy (RT), and recent literature has focused on immunotherapy and genetic advancements. Surgery can only be performed in cases detected at an early stage. Although both chemotherapy and radiotherapy are indispensable options for most patients, their impact on prognosis and survival is limited. Although promising developments are expected in immunotherapy, its impact on survival is still very limited, lasting only about 2 months. In patients undergoing surgical resection as part of their treatment, overall survival (OS) ranges from 34 to 69 months. OS for 1 year is 84.8-93.8%, for 3 years is 60-71.2%, and for 5 years is 51.1-63.8%. The five-year survival rates are reported as follows: stage I 31-63.8%, stage II 25-65.5%, stage III 15-27.8%, and stage IV 0%. In this study, the prognosis and factors affecting prognosis in SCLC were investigated in light of current literature from a surgical perspective, and predictions were attempted to be made to lay the groundwork for personalised treatment approaches. Compared to non-small-cell lung cancer, the number of studies is quite limited. Most of the surgical case series were conducted in the past, retrospectively, and involved a small number of patients. Advances in immunotherapy are promising. In the early stages, resection and subsequent chemotherapy may be the main treatment.
