Study Details

Study Description

Brief Summary

The COSMIC trial is a prospective, mono-centric, phase II trial evaluating toxicity and efficacy in the combined treatment with intensity-modulated radiation therapy (IMRT) and carbon ion (C12) boost. Primary endpoint is mucositis ≥ CTC°3, secondary endpoints are local control, disease-free survival, and toxicity. Planned accrual of the trial includes 54 patients with histologically proved (≥R1-resected, inoperable or Pn+) salivary gland malignancies. Treatment consists of 24 GyE carbon ions (8 fractions) and 50 Gy IMRT (2.0 Gy/ fraction).

Condition or Disease Intervention/Treatment Phase
  • Radiation: carbon ion boost
Phase 2

Detailed Description

Local control in malignant salivary gland tumours is dose dependent. High local control rates in adenoid cystic carcinomas could be achieved by highly conformal radiotherapy techniques and particle (neutron/ carbon ion) therapy. Considering high doses are needed to achieve local control, all malignant salivary gland tumours probably profit from the use of particle therapy, which in case of carbon ion treatment, has been shown to be accompanied by only mild side-effects.

Methods/ design:

The COSMIC trial is a prospective, mono-centric, phase II trial evaluating toxicity in the combined treatment with intensity-modulated radiation therapy (IMRT) and carbon ion (C12) boost in 54 patients with histologically proved (≥R1-resected, inoperable or Pn+) salivary gland malignancies. Patients receive 24 GyE carbon ions (8 fractions) and IMRT (2.0 Gy/ fraction).

Study objectives:

Incidence of mucositis ≥ CTC°3 will be assessed as the primary endpoint of the trial, local control, disease-free survival, toxicity (incl. mucositis CTC °I-II and late toxicity at 3 years post RT)

Arms and Interventions

Arm Intervention/Treatment
Experimental: IMRT + C12-boost

(8 x 3 GyE) carbon ion therapy followed by 50 Gy IMRT (2 Gy/ Fx)corresponding to a total dose of approximately 74 GyE.

Radiation: carbon ion boost
8 fractions carbon ion (8 x 3 GyE C12) therapy followed by 25 fractions of IMRT corresponding to a total dose of approximately 74 GyE. Treatment duration is approximately 61/2-7 weeks

Outcome Measures

Primary Outcome Measures

  1. mucositis ≥ CTC°3 [6-8 weeks post completion of treatment]

Secondary Outcome Measures

  1. local control [3 years post RT]

    to evaluate local control at 3 years post RT

  2. acute toxicity [6-8 weeks post completion of treatment]

    evaluation of acute radiation effects (other than mucositis CTC°C) 6-8 weeks post completion of treatment

  3. late toxicity [3 years post radiotherapy]

    to evaluate radiation late effects

  4. disease-free survival [3 years post treatment]

    to evaluate disease-free survival at 3 years post radiotherapy
