Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with histologically confirmed stage I-III esophageal or gastroesophageal junction adenocarcinoma who are suitable for trimodality therapy.

Probably not a fit

Patients with distant metastatic disease or those who are not candidates for esophagectomy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase II trial evaluates the effectiveness of preoperative hypofractionated radiation therapy combined with the chemotherapy regimen FOLFOX for patients with stage I-III esophageal or gastroesophageal junction adenocarcinoma. The study aims to demonstrate that this treatment approach can achieve a pathologic complete response comparable to historical controls while assessing the associated toxicities and patient quality of life. Participants will undergo a series of assessments, including toxicity evaluations and survival analyses, to determine the overall impact of this treatment strategy. Additionally, the study will explore the role of circulating tumor DNA and genetic sequencing in predicting treatment response and toxicity.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and reduce side effects for patients with esophageal cancer.

How similar studies have gone: Other studies have shown promise with similar approaches, but this specific combination of hypofractionated radiotherapy and FOLFOX is being evaluated for the first time in this context.
