About this trial

This is a multicentre non-randomized phase II study of proton beam radiotherapy in patients with thymic epithelial tumours (i.e. thymoma and thymic carcinoma) in the post-operative setting or in inoperable patients with localized disease.

Patients not willing or for any reason unsuitable to undergo proton treatment will be asked to participate in a follow-up assessment after the regular photon treatment in the same manner as the included patients.

Primary endpoints are:Toxicity (e.g. cardiac and pulmonary toxicity) and Local control at 5 year Secondary endpoints: PFS, Overall survival, Quality of life, measured by EORTC QLQ 30 + LC 13 and relapse pattern
