What this trial studies

This clinical trial investigates the effectiveness of daily online adaptive radiotherapy (oART) for patients with anal cancer. It aims to determine if this approach can significantly reduce early gastrointestinal toxicity compared to traditional non-adaptive intensity modulated radiation therapy (IMRT). The study is a single-arm, prospective trial conducted at a single center, focusing on patients who are eligible for curative radiotherapy. Participants will receive daily adjustments to their treatment based on real-time imaging and anatomical changes.

Who should consider this trial

Good fit: Ideal candidates include individuals with biopsy-verified anal cancer who are eligible for curative radiotherapy.

Not a fit: Patients with other malignant diseases within the past five years may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to reduced side effects from treatment, improving the quality of life for patients with anal cancer.

How similar studies have performed: Other studies have shown promise with adaptive radiotherapy approaches, suggesting potential benefits in reducing treatment-related toxicities.
