NCT04822077

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

Outcome Measures

Primary Outcomes (2)

  • Cardiotoxicity and pulmonary toxicity of therapy

    Proportion of patients with cardiac and pulmonary toxicity measured by CTCAE 4.0 \> Grade 2

  • Local tumor control

    Freedom from tumor progression (CR,PR or SD) mesured by CT-scan

    At 60 months from treatment

Secondary Outcomes (3)

  • Quality of life questionnaire EORTC QLQ 30 (European Organisation for Research and Treatment of Cancer)

    At 60 months from treatment

    At 60 months from treatment

  • Survival

    From treatment and for 5 years

Study Arms (1)

Proton radiotherapy

EXPERIMENTAL

Proton 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)

Radiation: Proton radiation

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)
