Is this trial a fit for you?

Likely a good fit

Adults (≥18) with histologically confirmed poorly differentiated T1–T2N0M0 glottic squamous cell carcinoma who are eligible for curative-intent radiotherapy or postoperative radiotherapy after surgery.

Probably not a fit

Patients with better-differentiated tumors, higher-stage disease, prior head and neck irradiation, or contraindications to radiotherapy may derive little to no benefit.

What this trial studies

This multicenter, prospective, single-arm phase II study assesses intensity-modulated radiotherapy (IMRT) as a curative treatment for adults with T1–T2N0M0 glottic squamous cell carcinoma with poor differentiation. Eligible patients may receive IMRT as definitive therapy or as postoperative radiotherapy after surgery, aiming to improve local control compared with historical expectations for poorly differentiated tumors. The study excludes patients with higher differentiation, prior chemoradiotherapy, or other active cancers, and requires good performance status (ECOG 0–1). Enrollment centers on the Second Affiliated Hospital of Zhejiang University School of Medicine in Hangzhou, China, with a focus on standardized radiotherapy delivery and close follow-up to assess outcomes. The trial is designed as multicenter in design but currently lists a single participating institution, reflecting its early scope.

Why it matters

Potential benefit: If successful, patients with poorly differentiated early glottic cancer could achieve better tumor control and potentially improved voice outcomes.

How similar studies have gone: Previous retrospective data have suggested radiotherapy approaches may offer better local control than surgery alone in poorly differentiated cases, but prospective multicenter data are lacking.
