Brief Summary
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

Study Arms (1)
Proton radiotherapy
EXPERIMENTALProton radiotherapy with RBE doses: * Patients with radical surgery and unfavourable histology (B2, B3, C) and/or Masaoka-Koga stage III, IVa: 2 Gy(RBE), once daily, five days a week to a total dose of 50 Gy(RBE). * Patients with non-radical surgery (R1 resection) regardless of stage and histology: 2.3 Gy(RBE), once daily, 5 days a week to a total dose of 57.5 Gy(RBE) * Inoperable patients regardless of stage and histology and patients with R2 non-radical resection: 2.5 Gy (RBE), once daily, 5 days a week to a total dose of 62.5 Gy(RBE)
Interventions
* Patients with radical surgery and unfavourable histology (B2, B3, C) and/or Masaoka-Koga stage III, IVa: 2 Gy(RBE), once daily, five days a week to a total dose of 50 Gy(RBE). * Patients with non-radical surgery (R1 resection) regardless of stage and histology: 2.3 Gy(RBE), once daily, 5 days a week to a total dose of 57.5 Gy(RBE) * Inoperable patients regardless of stage and histology and patients with R2 non-radical resection: 2.5 Gy (RBE), once daily, 5 days a week to a total dose of 62.5 Gy(RBE)
Eligibility Criteria
You may qualify if:
- Histological or cytological diagnosis of thymoma or thymic carcinoma.
- With radical surgery: stage III and IVa and selected stage II with type B2, B3 and thymic carcinoma according to local routine. With non-radical surgery (R1 or R2) or inoperable patient/ patient refusing surgery: stage I - IVa, any histology
- PS WHO 0 - 2.
- FEV1 \> 1L or \>40 % of predicted and CO diffusion capacity \> 40% of predicted (postoperative measures)
- Age \>18 years, no upper age limit.
- Written informed consent from patients.
You may not qualify if:
- Masaoka-Koga stage IVb (distant metastases).
- Pregnancy.
- Serious concomitant systemic disorder incompatible with the study.
- Tumour motion \> 0.5 cm on two repeated 4DCT
