Effectiveness of nanoparticle albumin-bound paclitaxel plus carboplatin in non-small lung cancer patients with malignant pleural effusion
Malignant pleural effusion (MPE) is a common complication occurring in cancer patients, and its management affects the prognosis of these patients. Preclinical and clinical studies have reported that treatment with nanoparticle albuminbound paclitaxel (nab-paclitaxel) plus carboplatin (CBDCA) is effective against intraperitoneal malignant tumors. To investigate the effectiveness of nab-paclitaxel plus CBDCA therapy for MPEs arising in patients with non-small cell lung cancer (NSCLC), we
... (NSCLC), we retrospectively analyzed the clinicopathological characteristics of 40 patients with stage IIIb or IV NSCLC who were treated with nab-paclitaxel plus CBDCA from 2013 to 2016. Out of 26 patients with MPEs who were treated with nab-paclitaxel plus CBDCA in this study, 21 patients (80.8%) had effective responses in MPEs; 6 of 21 patients exhibited complete responses (23.1%) and 15 of 21 had partial responses (57.7%). Kaplan-Meier survival curves and log-rank tests to evaluate the effectiveness of nab-paclitaxel plus CBDCA therapy against MPEs showed longer median progression-free survival (323 days vs. 26 days; p=0.009) and overall survival (not reached vs. 199 days; p=0.047) in patients with complete responses compared with those who achieved no response. There were no statistical differences between therapeutic effects on MPEs and those on systemic lesions. Nab-paclitaxel plus CBDCA therapy may be a preferred therapeutic option for patients with NSCLC who experience MPEs, and its effectiveness in treatment of MPEs may need to be evaluated separately from its therapeutic responses in systemic lesions.
