Appraisal of the Modified Cancer Cachexia Index in Locally Advanced Gastric Cancer Patients Undergoing Neoadjuvant Chemotherapy

Fujian Medical University600 enrolled

Overview

In this study, consecutive 600 patients with LAGC(cT2-4NanyM0) who underwent NACT between Jan. 2010 and Jun. 2022 were identified from two tertiary hospitals. The mCXI was constructed based on Random Forest model, calculated as (post-NACT L3 subcutaneous adipose tissue area \[SAT\])×(post-NACT serum albumin \[ALB\])/(post-NACT platelet count \[PLT\]). Patients were categorized into two subgroups: mCXI-low and mCXI-high. mCXI is associated with the overall prognosis in patients with locally advanced gastric cancer underwent neoadjuvant chemotherapy, is superior to traditional CXI, and may serve as a decision-making tool for guiding personalized postoperative adjuvant chemotherapy.

This is a multicenter retrospective cohort study
