PRIMARY OBJECTIVE:~I. To determine the safety and efficacy of propranolol hydrochloride (propranolol) in combination with standard neoadjuvant/definitive chemoradiation therapy (CRT) for esophageal cancer.~SECONDARY OBJECTIVE:~I. To estimate overall survival (OS) and pathologic response rate in patients that undergo surgery.
This phase II trial studies the side effects and best dose of propranolol when administered concurrently with SOC neoadjuvant CRT in patients with esophageal carcinoma, with a safety lead-in and dose expansion cohort. Patients who are already on β-blockers will receive standard of care CRT and will be considered separately as a single arm prospective cohort
