Toxicity and efficacy of gemcitabine plus NAB-paclitaxel (paclitaxel + albumin) in a Russian patient population: results of a multicenter retrospective study

Introduction. The results of randomized MPACT study have demonstrated that the addition of nab-paclitaxel to gemcitabine leads to a statistically significant increase in life expectancy. The main objective of this retrospective study was to obtain up-to-date efficacy and toxicity data for this drug combination in Russian real-world clinical setting. Materials and methods. The study enrolled patients with morphologically confirmed locally advanced or metastatic pancreatic cancer who had ECOG Performance Status scores of 0-2 and received treatment with gemcitabine and nab-paclitaxel. Immediate and long-term outcomes, as well as treatment toxicity and dose modifications, were assessed. Results. The study included 142 patients who received treatment from 2009 to 2019 at 17 centers in 11 regions of Russia. Full dose gemcitabine and nab-paclitaxel were administered at baseline in 74 % of the cases. The median number of chemotherapy cycles was 4 (range, from 1 to 16). Nab-paclitaxel dose was reduced in 32 % of the cases, and that of gemcitabine in 23 % of them...
