Purpose: Patients with non-small cell lung cancer (NSCLC) and malignant pleural effusion (MPE) are difficult to manage clinically. In this study, we designed a protocol of combined ipsilateral pleura radiotherapy with intrapleural(i.p.) and intravenous(i.v.) chemotherapy to enhance local as well as systemic control of the disease.Method: From January 2006 to January 2011, 31 patients with NSCLC and MPE were eligible for the study. After adequate drainage, patients received chemotherapy (cisplatin 60mg/m 2 i.p. on day 1, paclitaxel 125mg/m 2 and cisplatin 75mg/m 2 on days 3 and 31 i.v.), and after first cycle chemotherapy followed by forward IMRT. Radiation targets included primary tumor, mediastinal, lymphatic drainage area, the ipsilateral pleura and 1/2 pleural effusion. The radiation dose is 190cGy / fraction. After 6080cGy/32 fractions delivered, residues tumours were given with boost irradiation 570~950 cGy /3~5 fractions.Result: Overall response of pleural effusion was 90.3% with 38.7% complete remission, 51.6% with partial remission, 6.5% stable disease, and 3.2 % progressive disease. The median failure-free and overall survival was 13 and18 months, respectively. 1-and 2-years overall survival was 77.3% and 19.9%. Grade 1, 2, 3 and 4 of lung and esophagus acute radiation-induced toxicity was 58.1%,19.4%,3.2% and 0% and 48.4%9.7%, 3.2% and 0%. The rate of grade 1, 2, 3 and 4 with hematologic toxicity was 38.5%, 23.1%, 3.8%, and 0%.
Conclusion:Ipsilateral pleura radiotherapy combined with intrapleural and intravenous Chemotherapy for patients with NSCLC presenting malignant pleural effusion is feasible, effective, and provides an alternative treatment modality for them.
