Pulsed Low Dose Rate Radiation With Concurrent Chemotherapy for Non-Small Cell Lung Cancer and Esophageal Cancer

Summary

Phase I study with the hypothesis that Pulsed Low Dose Radiation (PLDR) radiation delivery technique can significantly decrease the rate of severe acute esophagitis in patients receiving concurrent Chemo-radiation therapy (CRT) for non-small cell lung cancer or esophageal cancer while maintaining similar efficacy. For these patients, the rate of severe acute esophagitis during concurrent CRT is high (approximately 20%) when conventional external beam radiation is utilized. Severe acute esophagitis can cause many adverse consequences such as severe discomfort, weight loss, hospitalization, interruption/early termination of treatment, and worse surgical complications for those who receive surgery after CRT. PLDR radiation has the potential to maintain the tumor control rates of conventional radiation while decreasing the toxicity to the surrounding normal tissue 29-35.

We have completed accrual to a phase I PLDR radiation study, in which patient received palliative re-irradiation with PLDR technique for their metastatic disease in previous irradiated field. In that phase I study, PLDR demonstrated safety for acute toxicities in the setting of re-irradiation for a total dose of 50 Gy, with analysis of 60 Gy pending. The follow up time for that phase I study is limited as most enrolled patients have short overall survival due to their terminal illness.

This proposed phase I study is, to our knowledge, the first clinical study with combination of PLDR radiation and concurrent chemotherapy for definitive treatment.

Interventions

RADIATION

Pulsed Low Dose Radiation

Treatment naïve patients with non-small cell lung cancer or esophageal cancer whose planned treatment regimen is concurrent CRT followed by surgery. The total radiation dose will be 50.4 Gy in daily fraction of 1.8 Gy for esophageal cancer and 60 Gy in daily fraction of 2 Gy for non-small cell lung cancer. The concurrent chemo regimen will carboplatin-paclitaxel managed by the treating medical oncologist. Patients are planned to receive surgery at approximately 6 to 9 weeks after finishing CRT with surgical aspects determined by the treating surgical oncologist.

DRUG

Carboplatin

Treatment naïve patients with non-small cell lung cancer or esophageal cancer whose planned treatment regimen is concurrent CRT followed by surgery.

The concurrent chemo regimen will carboplatin-paclitaxel managed by the treating medical oncologist. Patients are planned to receive surgery at approximately 6 to 9 weeks after finishing CRT with surgical aspects determined by the treating surgical oncologist.
