What does this research mean for the field?

Preoperative time-dependent changes in BMI (ΔBMI/day) are an independent predictor of worse progression-free survival in gastric cancer patients and provide better prognostic insights than static, single point-in-time BMI measurements. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This study aims to determine if time-dependent changes in BMI are more predictive of outcomes in gastric cancer than static BMI measurements.

Overview

Retrospective analysis shows that changes in BMI provide better prognosis prediction in gastric cancer, suggesting time-sensitive monitoring is crucial.

Key Points

This study aims to determine if time-dependent changes in BMI are more predictive of outcomes in gastric cancer than static BMI measurements.
Retrospective analysis of 140 gastric cancer patients
BMI measured preoperatively and at hospitalization for surgery
Analysis of the association between ΔBMI/day and survival outcomes, adjusted for confounding factors.
ΔBMI/day was significantly associated with time to surgery (P = 0.001) and intraoperative blood loss (all Ps <0.001)
Large ΔBMI/day linked to worse progression-free survival (hazard ratio 2.81, 95% CI 1.07–7.42, P = 0.037)
Static BMI measurements were not associated with progression-free survival.
