Abstract

Background. Nab-paclitaxel is a nanodispersed albumin-stabilized paclitaxel. This structure significantly changes the properties of paclitaxel, because albumin provides delivery and accumulation of paclitaxel in tumor tissue, and also affects its undesirable effects. Objective. Evaluation of the efficacy and safety of a combination of gemcitabine and nab-paclitaxel in patients with locally advanced and advanced pancreatic cancer. Methods. The data on treatment with nab-paclitaxel and gemcitabine in standard dosages in 23 patients with locally advanced and advanced pancreatic cancer were analyzed. The direct clinical effect, overall and progression-free survival, and adverse events associated with antitumor therapy were evaluated. Results. The objective antitumor effect (PR) was 26.1% (6), and 73.9% (17 patients) achieved tumor control (PR + CD). The median PFS was 6.0 months, OS - 9.7 months. The most common adverse events included neutropenia (34.7%), thrombocytopenia (34.7%), and anemia (43.5%). Non-hematologic toxicity was much less common. In some patients, complications led to the dose reduction (17.4%), delayed administration of cytostatics (17.3%), and discontinuation of therapy (4.3%). Conclusion Nab-paclitaxel in combination with gemcitabine has demonstrated clinical efficacy in the treatment of locally advanced and advanced pancreatic cancer, comparable to the results of international and retrospective Russian studies. This combination is characterized by a favorable toxicity profile and can be used, among others, in weakened patients with ECOG 2. It is necessary to carefully monitor non-hematological adverse events, because, despite their relative rarity, their severity and nature can significantly affect the treatment of patients with this severe oncopathology
