简要总结
The investigators aim to evaluate the safety of delivering a one-time single fraction of Lattice Extreme Ablative Dose (LEAD) radiotherapy followed one day later by standard-dose, conventionally fractionated concurrent chemotherapy and radiation delivered over 6 weeks in patients with bulky stage III non-small cell lung cancer in the setting of a single-arm phase I clinical trial. The investigators hypothesize that the addition of a one-time single fraction of LEAD radiation is safe and feasible, and will not result in additional toxicity above that expected with standard-dose concurrent chemotherapy and radiation alone.
详细描述
Paarticipants will receive a single fraction of LEAD radiation on day 1, followed one day later by conventionally fractionated concurrent chemoradiation consisting of 60 Gy of radiation delivered to involved sites of disease and a platinum doublet.
The investigational radiation treatment, a single fraction of LEAD radiation, is to be followed by conventionally fractionated radiation delivered concurrently with a standard chemotherapy regimen for stage III non-small cell lung cancer. The following day, patients will begin concurrent chemotherapy and radiation. Chemotherapy will be delivered under the management of the treating medical oncologist. Chemotherapy must be a platinum doublet. Carboplatin and cisplatin are both considered acceptable platinum agents. The use of cisplatin over carboplatin is strongly encouraged, unless the patient has a contraindication to cisplatin. The second agent will be at the discretion of the treating medical oncologist; in the current era, chemotherapy agents are tailored to each patient based on tumor histology, as well as comorbidities that dictate the tolerance of certain chemotherapeutic agents. Chemotherapy will be delivered concurrently throughout radiation therapy, beginning on day 2 of the treatment protocol and on the same day as the start of standard-dose radiation. Weekly regimens or regimens delivered every 3 weeks are acceptable. Additional cycles of consolidation chemotherapy are encouraged and will be given at the discretion of the treating medical oncologist.

结局指标
主要结局
Rate of Treatment-related Toxicity in Study Participants
时间窗: Up to 12 months
Rate of treatment-related toxicity (serious adverse events, adverse events, etc.) in study participants. Toxicity will be assessed using NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The two toxicities that will be monitored as primary endpoints are esophagitis and pneumonitis.
