The correlation between paclitaxel chemotoxicity and the plasma albumin level in cancer patients

Abstract

What Is Known and Objective: The aim of this study was to evaluate the pharmacokinetics of paclitaxel in cancer patients with hypoalbuminemia following paclitaxelcontaining chemotherapy and to provide a reference for the prevention of adverse events (AEs) after paclitaxel administration.Methods: Peripheral blood was collected from cancer patients treated with paclitaxel.The plasma concentration of paclitaxel was determined by ultra-high performance liquid chromatography after 24 ± 8 h of chemotherapy, and individual paclitaxel time above a threshold concentration of 0.05 μmol/L (T c>0.05 ) was calculated using the population pharmacokinetic model. Haematological and non-haematological toxicities were monitored after chemotherapy, and the correlation between different chemotherapy toxicities and T c>0.05 was evaluated using the Prism software.Results and Discussion: The enrolled patients were divided into the hypoalbuminemia group and normal albumin level group. The mean T c>0.05 values in the normal albumin level and hypoalbuminemia groups were 36.89 and 24.93 h, respectively (P < 0.001). The risk of myelosuppression was positively correlated with T c>0.05 . Due to the lower T c>0.05 , the incidences of immediate AEs such as gastrointestinal reactions and rashes were higher in the hypoalbuminemia group than in the normal albumin level group, and the incidences of delayed AEs such as myelosuppression and neurotoxicity were lower in the hypoalbuminemia group.What Is New and Conclusions: Plasma albumin level has a conclusive effect on T c>0.05 , which can predict the potential clinical toxicity of paclitaxel. The study provides a theoretical basis for administration of paclitaxel.

Hypoalbuminemia and colorectal cancer patients: Any correlation?: A systematic review and meta-analysis

“…In the context of CRC, BSA has been characterized as a prognostic factor linked with survival and a predictor of surgical morbidity and death. [6,9,10] BSA measurement is simple, affordable, accurate, and trustworthy, frequently used to determine patients general state with many types of medical conditions. Consequently, we aimed to evaluate the predictive value of preoperative hypoalbuminemia in patients undergoing colorectal surgery.…”
