简要总结
This randomized phase III trial studies proton chemoradiotherapy to see how well it works compared to photon chemoradiotherapy in treating patients with stage II-IIIB non-small cell lung cancer that cannot be removed by surgery. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor, such as photon or proton beam radiation therapy, may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as paclitaxel, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether proton chemoradiotherapy is more effective than photon chemoradiotherapy in treating non-small cell lung cancer.
详细描述
PRIMARY OBJECTIVES:
I. To compare the overall survival (OS) in patients with stage II-IIIB non-small cell lung cancer (NSCLC) after image guided, motion-managed photon radiotherapy (Arm 1) or after image guided, motion-managed proton radiotherapy (Arm 2) both given with concurrent platinum- based chemotherapy.
II. To compare the cardiac toxicity and lymphocyte reduction (lymphopenia) definitely, probably, or possibly related to treatment between the 2 arms.
SECONDARY OBJECTIVES:
I. To compare 2-year progression-free survival (PFS) between the 2 arms. II. To compare the development of grade 3 or higher adverse events not included above that are definitely, probably, or possibly related to treatment.
