What this trial is about
This is a phase III clinical trial that aims to evaluate whether increasing the dose of radiotherapy given twice a day can improve treatment outcomes in patients with localized small cell lung cancer (SCLC). All patients will receive standard chemotherapy with cisplatin and etoposide and will be randomly assigned to one of three radiotherapy regimens. The main objective is to determine whether this intensified radiotherapy improves progression-free survival and overall survival. The study will also compare two different dose escalation strategies and assess treatment side effects and patients' quality of life. This research may help identify a more effective treatment approach for patients with limited-stage SCLC and could contribute to improving long-term survival in this aggressive type of cancer
