Abstract
Abstract Background: Malignant pleural effusion in breast cancer has been associated with poor prognosis which median survival rate is 5–16 months. The response rate of local treatment has been very low and in some case, complications have resulted in death. Patients and methods: We investigated the efficacy and safety of paclitaxel, as an intrapleural chemotherapeutic agent. From January 2006 to June 2015, total 35 times of intrapleural chemothepapy were performed in 26 breast cancer patients who had developed malignant pleural effusion. They were infused 120mg/m2 of paclitaxel through a chest tube, which was clamped for 48 hours. The chest tube was maintained until drainage was reduced to less than 50-100 mL/day. Results: Mean follow up period after intrapleural chemotherapy was 11 months.The average time of indwelling with a chest tube after intrapleural chemotherapy was 9.7 days. Mean progression free survival was 7.8 Months. During the follow-up period, 5 patients had no progression of pleural effusion and 2 of them were free from progression for more than 36 months. In 26 attempts, there were effective and could remove chest tube otherwise In 9 attempts, there were no improvement after intrapleural chemotherapy. 1 patients received a second round of ipsilateral intrapleural chemotherapy and had no response unlike earlier attempts. There were 3 severe adverse effect related death caused by respiratory failure with or without G4 neutropenia. Conclusion: Intrapleural paclitaxel chemotherapy is helpful for some cases of uncontrolled pleural effusion in that reduce the duration of hospital stay and improve quality of life. But it will be determined carefully, considering the side effects and response rate of treatment. Citation Format: Yeu KJ, Park J, Choi JE, Kang SH, Lee SJ.
