Prognostic factors in patients with small-cell carcinoma of the lung

Fifty-two patients with histologically confirmed small-cell carcinoma of the lung, 15 with disease localized to one hemithorax and 37 with extensive metastases, were studied. Only patients whose general condition was considered good enough to tolerate intensive combination chemotherapy were included in this study. The median survival time of these patients was 33 weeks (range 7-192 weeks) with a mean survival time of 43 weeks. Patients who responded with objective tumour improvement within 6 weeks had a median survival time of 39 weeks. Those showing disease stabilization at 6 weeks had a median survival time of 35 weeks while those having disease progression at this time had a median survival of 22 weeks. Patients without liver involvement and a normal serum albumin level at the start of treatment had statistically superior survival times.     

The role of radiation therapy in malignant pleural mesothelioma: a systematic review.

INTRODUCTION: Radiation therapy may offer patients presenting with malignant pleural mesothelioma (MPM) symptom palliation and improvements in quality of life. This systematic review will address the role of radiation therapy in the management of MPM. METHODS: A thorough systematic search of the literature was conducted for published articles and conference proceedings for applicable abstracts. Relevant trials were selected and assessed. RESULTS: Three small randomized controlled trials compared prophylactic external beam radiation therapy to no radiation therapy for patients with thoracic tracts caused by drainage tubes or diagnostic procedures. None of those trials reported any serious adverse effects. A pooled analysis found no significant reduction in the frequency of procedure tract metastases. Four non-comparative studies have shown that hemithoracic irradiation alone resulted in significant toxicity, including radiation-induced pulmonary fibrosis, radiation pneumonitis, and bronchopleural fistula, without any survival benefit. Few of the identified studies reported on symptom control, and no studies included formal measures of quality of life. CONCLUSION: There is limited evidence for the role of radiotherapy in the management of patients with MPM. Future studies including radiotherapy for the treatment of such patients should include formal measures of quality of life and symptom control.
