Active surveillance for oesophageal cancer after chemoradiotherapy

A Prospective Cohort Study on Active Surveillance After Neoadjuvant Chemoradiation for Oesophageal Cancer: SANO-2 Study

Observational Erasmus Medical Center · NCT04886635

This study is testing whether closely monitoring patients with locally advanced oesophageal cancer after they finish chemoradiotherapy can be a safe and effective alternative to immediate surgery.

What this trial studies

This study investigates an active surveillance approach for patients with locally advanced oesophageal cancer who have completed neoadjuvant chemoradiotherapy. It aims to monitor the safety and effectiveness of this approach in a prospective cohort, as current evidence suggests that active surveillance may be a viable alternative to immediate surgery. The study is an extension of the SANO trial, which has shown high participation rates and a demand for tailored surgical approaches based on patient preferences. Continuous monitoring of safety and implementation will be conducted until the final results of the SANO trial are available.

Who should consider this trial

Good fit: Ideal candidates include operable patients aged 18 and older who have recently undergone neoadjuvant chemoradiotherapy for histologically proven oesophageal cancer.

Not a fit: Patients with non-FDG-avid tumors, those who have undergone endoscopic resection, or those requiring definitive chemoradiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive treatment option for patients with oesophageal cancer, potentially improving their quality of life.

How similar studies have performed: Other studies have shown promising results with active surveillance approaches in similar contexts, but this specific study is an extension and may provide novel insights.
