Nanomedicine holds great promise for fighting against malignant tumors. However, tumor elevated interstitial fluid pressure (IFP) seriously hinders convective transvascular and interstitial transport of nanomedicines and thus damages its antitumor efficacy. In this study, combretastatin-A4 phosphate (CA4P) was utilized to reduce tumor IFP, and thereby to improve the intratumoral distribution and antitumor efficacy of nanoparticle albumin-bound paclitaxel (nab-paclitaxel). IFP was measured using the wick-in-needle method in tumors growing subcutaneously pretreatment and posttreatment with a single intravenous injection of CA4P. The tracing method of iodine 131 isotope was used for biodistribution analysis of nab-paclitaxel. Liquid chromatography coupled with tandem mass spectrometry was used to detect the intratumoral concentration of paclitaxel. Magnetic resonance imaging was applied to monitor tumor volume and ratios of necrosis. The tumor IFP continued to decline gradually over time following CA4P treatment, reaching approximately 31% of the pretreatment value by 1 h posttreatment. Biodistribution data indicated that both 131I-nab-paclitaxel and paclitaxel exhibited higher tumor uptake in CA4P + 131I-nab-paclitaxel group compared with I131-nab-paclitaxel group. Nab-paclitaxel combined with CA4Pshowed significant tumor growth inhibition and higher tumor necrosis ratio relative to PBS, CA4P and nab-paclitaxel group, respectively. In conclusion, CA4P improved the intratumoral distribution and antitumor efficacy of nab-paclitaxel in W256 tumor-bearing rats.
