Prevention of Radiation Pneumonitis After Three-dimensional Conformal Radiation Therapy (3D-CRT) in Patients With Non-small-cell Lung Cancer

France242 participantsStarted 2006-07

Plain-language summary

The purpose of this study is to evaluate the interest of breath holding for the prevention of radiation pneumonitis following conformal radiation therapy. Eligible patients will be randomly assigned in a 2-arm trial to free breathing or breath holding during conformal radiation. The primary objective of the study is to establish the efficacy of breath holding, compared to free breathing, in the prevention of early pulmonary toxicity following conformal radiation. Several departments of radiotherapy, many pneumology units and two basic and applied research laboratories take part in this multicentric study. The number of patients required to demonstrate a reduction in radiation pneumonitis from 45 % to 22.5 %, assuming an alpha risk of 5% in a two-sided test and 95% power, is 240 (120 per arm). With a planned accrual of 7 patients per month, it is estimated that the inclusion period should be approximately 3 years.

Inclusion Criteria: * Non-metastatic cytologically or histologically proven non-small-cell lung cancer (NSCLC) * Operated NSCLC patients requiring post-surgical irradiation or non-operated NSCLC patients requiring curative irradiation * Conformational thoracic radiotherapy with curative intent * Age \>= 18 * Complete functional respiratory evaluation (FRE) performed less than 2 months before inclusion, demonstrating a maximum expiratory flow-volume/second \> 1 l (in case surgery, the FRE must have been realized in the post-surgery period) * Thoracic CT-scan performed less than 2 months before inclusion for non-operated patient * PET-scan performed less than 2 months before inclusion for non-operated patient * Performance status (PS) ECOG \<= 1 * Possible training on breath holding technique * Female patients of childbearing potential: effective method of contraception necessary * Mandatory affiliation with a social security system * Written, signed, informed consent Exclusion Criteria: * Small-cell lung cancer * Metastatic disease * Infiltrating pulmonary disease * Previous thoracic irradiation * Indication of irradiation with palliative intent * Previous or concurrent primary malignancies at other sites (except basocellular skin cancer or cervical cancer in situ or complete remission for more than 5 years) * Life expectancy \< 6 months * Patient understanding incompatible with the breath-hold technique (patients with major presbycusis are not eligible) * Pregnant or lacta…
