Effect of intrapleural anti-Vascular Endothelial Growth Factor (VEGF) associated with nab paclitaxel in a murine model of malignant pleural effusion

Abstract Background Malignant pleural effusion (MPE) is a disease associated with poor prognosis, high morbidity, and significant mortality. Murine models of MPE have successfully replicated its formation and metastases, providing valuable insights into potential therapeutic approaches. Nanoparticle...

description Abstract Background Malignant pleural effusion (MPE) is a disease associated with poor prognosis, high morbidity, and significant mortality. Murine models of MPE have successfully replicated its formation and metastases, providing valuable insights into potential therapeutic approaches. Nanoparticle-associated drugs (nab) offer the advantage of reduced toxicity while enhancing their effectiveness against tumor cells. This study aims to evaluate the efficacy of intrapleural nab-Paclitaxel, either alone or in combination with anti-vascular endothelial growth factor (VEGF), in a murine model of MPE. Methods Lewis Lung Carcinoma (LLC) cells were injected intrapleurally into 300 mice. After seven days, the mice were assigned to one of five treatment groups: intrapleural administration of Paclitaxel, nab-Paclitaxel, anti-VEGF, nab-Paclitaxel + anti-VEGF, or saline (untreated). Twenty animals per group were monitored weekly for weight, mobility, and survival. Additionally, ten mice from each group were euthanized on days 7, 14, 21 and 28 to assess pleural fluid volume, cytology, lactate dehydrogenase (LDH), interleukin-6 (IL-6), VEGF, transforming necrosis factor (TNF)-α, and histological characteristics. Results Pleural carcinomatosis was lethal across all groups; however, mice receiving nab-Paclitaxel + anti-VEGF exhibited the longest survival. Pleural fluid accumulation was most pronounced in the untreated and Paclitaxel groups, whereas the lowest levels were observed in the nab-Paclitaxel + anti-VEGF group. Tumor implantation in the pleura occurred in all groups, but the lowest scores were recorded in mice treated with nab-Paclitaxel + anti-VEGF. Conclusions In this experimental MPE model, intrapleural administration of nab-Paclitaxel in combination with anti-VEGF significantly prolonged survival and reduced both pleural fluid volume and tumor implantation.
