[en] The use of hypofractionated radiotherapy regiments is becoming more widely recognized in the palliation of non-small cell lung carcinoma (NSCLC). Anecdoctal reports of chest pain, rigors and fevers in the hours that follow radiotherapy led us to perform a survey estimating the frequency and severity of these symptoms following treatment to the thorax. We conclude that patients receiving palliative radiotherapy for bronchial carcinoma often develop significant symptoms in the hours following treatment. The timing and duration suggest a relationship with the radiotherapy, and we feel that patients should be warned of the possible occurrence of these symptoms. (author)
