Background: Although sentinel node (SN) biopsy has been applied for various types of solid tumors, its clinical significance is currently limited to the field of diagnostics. We developed a new translymphatic chemotherapy approach using a novel phospholipid polymer (PMB30W), which facilitates the dissolution of large amounts of paclitaxel. The purpose of the present study was to investigate the pharmacokinetics and antitumor effect of this conjugate (PTX-PMB30W) in a rat model. Materials and Methods: PTX-PMB30W was directly administered into the cecal submucosa or through the tail vein. The antitumor effect was compared between the two groups. Results: Paclitaxel concentrations in SNs remained constant over a 24-h period after local administration. Tumor growth was clearly suppressed by submucosal administration of PTX-PMB30W, resulting in a survival benefit compared to intravenous administration. Conclusion: Translymphatic chemotherapy targeting SNs via direct administration of PTX-PMB30W appears feasible, and this strategy may be applicable to the multi-disciplinary management of early solid cancer.
