Abstract

Background

Survival and prognostic variables in patients with advanced or metastatic non-small cell lung cancer (NSCLC) requiring thoracic palliative radiotherapy using a moderately hypofractionated regime (13–15 × 3 Gy) were evaluated.

Methods

From March 2006 to April 2012, 120 patients with a physician estimated prognosis of 6–12 months were treated with this regime using CT-based 3D conformal radiotherapy. We collected data on patient characteristics, comorbidities, toxicity, and treatment parameters.

Results

Radiotherapy was completed as prescribed in 114 patients (95.0 %, premature termination 5.0 %). Acute grade 3 toxicity was seen in 6.4 % of patients. The median survival of all patients was 5.8 months. Nonmetastatic patients survived significantly longer than patients with metastatic disease (median 11.7 months vs 4.7 months, p = 0.0001) and 18.6 % of nonmetastatic patients survived longer than 2 years. In 12.7 % radiotherapy started less than 30 days before death and 14.2 % of patients received radiotherapy within 14 days before death. In the multivariate analysis, good general condition, nonmetastatic disease, and a stable or improved general condition at the end of radiotherapy were significant. The treatment parameters, age, and comorbidities were not statistically significant.

Conclusion

Our data confirm considerable effectiveness of 13 × 3 Gy with conformal radiotherapy for patients with locally confined NSCLC not fit for radical treatment and raise doubt for this regimen in metastatic patients and ECOG ≥ 2 when burden, acute toxicity, and resources are considered.
