Study Summary

Rates of local disease control in patients with locally advanced esophageal cancer who are not candidates for surgical resection are suboptimal. Despite treatment with chemotherapy and radiation therapy approximately half of patients will develop recurrence of their cancer at the site of the original primary cancer. Salvage therapy options are largely ineffective and nearly all patients who develop local disease recurrence will succumb to their cancer. Recent clinical trials for lung cancer have demonstrated that local tumor control can be improved safely with accelerated hypofractionated radiation therapy regimens in order to achieve radiation dose intensification. This clinical trial aims to adapt those techniques and assess the safety of such a regimen for the treatment of inoperable thoracic esophageal cancers.

Primary Outcome

The MTD of the combination of radiation and FOLFOX will be estimated using the proposed TITE-CRM model. After the phase I study, the MTD will be chosen as the dose that yields a posterior toxicity estimate closest to 20% while being between 15% and 25%. Toxicity will be coded using CTCAE v5.0.
