A small-scale, exploratory real-world study of nab-paclitaxel combined with oxaliplatin and tegafur in the perioperative treatment of advanced gastric cancer: a study protocol for a real-world clinical trial

Abstract

Background: Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) is an optimized and improved derivative of paclitaxel with superior efficacy and fewer adverse reactions, and it is widely used in the treatment of advanced gastric cancer. However, there is a paucity of data regarding the safety and efficacy of nab-paclitaxel combined with oxaliplatin (LBP) and tegafur in the treatment of patients with advanced gastric cancer.

Methods: This analysis is a prospective, single-center, open-label, historically controlled real-world study designed to include 10 patients with advanced gastric cancer treated with nab-paclitaxel combined with LBP and tegafur gimeracil oteracil potassium. The primary and main efficacy outcomes are safety indicators, including the incidence of adverse drug reactions and adverse events (AEs), as well as the outliers of laboratory indicators and vital signs. The secondary efficacy outcomes are overall survival (OS), objective response rate (ORR), disease control rate (DCR), and proportion of dose suspensions, dose reductions and discontinuations.

Discussion: Based on the findings of previous studies, we wished to assess the safety and efficacy of nab-paclitaxel combined with LBP and tegafur in the treatment of advanced gastric cancer. The trial requires constant contact and monitoring. The purpose is to determine a superior protocol in terms of patient survival, and pathological and objective response.

Trial registration: This trial has been registered with the Clinical Trial Registry: NCT05052931 (registration date: 2021/9/12).
