文摘Small cell lung cancer(SCLC)accounts for approximately 20%of all lung cancers.The main treatment is chemotherapy(Ch).However,the addition of radiotherapy significantly improves overall survival(OS)in patients with non-metastatic SCLC and in those with metastatic SCLC who respond to Ch.Prophylactic cranial irradiation reduces the risk of brain metastases and improves OS in both metastatic and non-metastatic patients.The 5-year OS rate in patients with limited-stage disease(non-metastatic)is slightly higher than 30%,but less than 5%in patients with extensive-stage disease(metastatic).The present clinical guidelines were developed by Spanish radiation oncologists on behalf of the Oncologic Group for the Study of Lung Cancer/Spanish Society of Radiation Oncology to provide a current review of the diagnosis,planning,and treatment of SCLC.These guidelines emphasise treatment fields,radiation techniques,fractionation,concomitant treatment,and the optimal timing of Ch and radiotherapy.Finally,we discuss the main indications for reirradiation in local recurrence.
