Combined intrapleural and intravenous chemotherapy, and pulmonary irradiation, for treatment of patients with lung cancer presenting with malignant pleural effusion - A pilot study

Objectives: Patients with non-small-cell lung cancer (NSCLC) and malignant pleural effusion (MPE) are difficult to manage clinically and have a short life expectancy. In this pilot study, we designed a protocol of combined intrapleural (i.p.) and intravenous (i.v.) chemotherapy and pulmonary irradiation to enhance local as well as systemic control of the disease. Methods: From April 1998 to April 2000, 27 patients with NSCLC and symptomatic MPE were eligible for the study. Patients received pre-radiation chemotherapy (cisplatin 60 mg/m(2) i.p. on day 1; gemcitabine 1,000 mg/m(2) i.v. on days 1, 8, and 15, q4week x 3) after surgical implantation of i.p. and i.v. port-A, followed by radiotherapy (7,020 cGy/39fr), and, finally, post-radiation chemotherapy (docetaxel 60 mg/m(2) q(3)week x 3-6 i.v.). Results: Grade 1/2 nausea/vomiting and impaired renal function were more common from pre-radiation than post-radiation chemotherapy; however, grade 3/4 toxicities from pre-radiation chemotherapy were minimal. Conversely, grade 3/4 leukopenia and grade 1/2 alopecia, diarrhea, elevation of SGOT/SGPT, and sensory impairment were more common following post-radiation chemotherapy. Only two patients experienced recurrence of pleural effusion. The overall response rate was 55% with 7% complete remission, 48% partial remission, 22% stable disease, and 22% progressive disease. The median failure-free and overall survival was 8 and 16 months, respectively. The one-year survival rate was 63% (95% confidence interval, 45-80%). Conclusions: We conclude that the combination of i.p. and i.v. chemotherapy and pulmonary irradiation is feasible and should be tested in a larger clinical trial to determine whether survival can be improved for this cohort of patients.
