Quad Shot Radiotherapy Combined With Tislelizumab and Platinum-Based Chemotherapy Before Surgery for Stage II-III Non-Small Cell Lung Cancer
Summary
This study aims to evaluate a new pre-surgery (neoadjuvant) treatment for patients with stage II-III non-small cell lung cancer (NSCLC). Currently, standard pre-surgery treatment involves immunotherapy combined with chemotherapy. While effective, many patients still have residual tumor cells after this standard treatment. Radiation therapy can not only kill tumor cells but also help the immune system recognize and fight cancer. The type of radiation used in this study is called "Quad Shot" (QS) radiotherapy. It is a short, high-dose, cyclical treatment designed to boost the effects of immunotherapy with less toxicity than standard daily radiation. Patients in this study will receive 3 cycles of QS radiotherapy combined with Tislelizumab (an immunotherapy drug) and standard platinum-based chemotherapy before surgery. The main goal of this study is to see if this combined approach can make the tumor completely disappear under a microscope (called pathological complete response, or pCR). Researchers will also monitor the safety of the treatment, side effects, and how well patients tolerate the treatment before undergoing surgery. Approximately 12 patients will be enrolled in this study.
