Brief summary

This study will evaluate if proton beam therapy as part of chemoradiation results in a decrease in diffusion lung capacity of carbon monoxide (DLCO) compared to photon radiation therapy for esophageal carcinoma. A secondary objective is to determine effects on cardiac function, quality of life, and compare acute and late toxicities.

Detailed description

Radiation Modality: Proton radiotherapy will be offered to all patients that meet trial eligibility. If patients decline proton radiotherapy or are otherwise unable to receive proton therapy they will be included in x-ray cohort (group 2). Chemotherapy will be delivered at the discretion of the treating Medical Oncologist. Weekly carboplatin and paclitaxel at standard doses is preferred. It is recommended that the weekly chemotherapy regimen be continued throughout the course of radiotherapy. Chemotherapy should begin within 48 hours of beginning radiotherapy.

Interventions

59.4 Gy (RBE) in 1.8 Gy per fraction plus weekly chemotherapy at standard doses

Secondary

MeasureTime frameDescription
