Abstract
Background
Few studies have investigated the relationship between body mass index (BMI) and mortality or evaluated the prognostic validity of a grading system incorporating BMI and weight loss in Asian cancer patients. We conducted a study to investigate characteristics according to BMI and to confirm the prognostic validity of BMI and the grading system.
Methods
This study involved a secondary analysis of a prospective cohort study. Subjects were divided into six BMI groups and five grades according to the grading system. Characteristics were compared between the six groups. We conducted time-to-event analyses using the Kaplan–Meier method, log-rank test, and univariate and multivariate Cox regression analyses.
Results
A total of 1094 patients were classified into six BMI groups: <17 (n = 244), 17–18.4 (n = 211), 18.5–19.9 (n = 192), 20–21.9 (n = 196), 22–24.9 (n = 161), and 25 ≤ (n = 90). Regarding oedema, the prevalence increased with BMI, being 70% the 25 ≤ group. The prevalence of pleural effusion and ascites were the highest in the 25 ≤ group. Median survival ranged between 18 and 22 days in the six groups. No significant differences were observed in survival rates among the six BMI groups (log rank P = 0.83). No significant differences were observed in survival rates among the five grades (log rank P = 0.25).
Conclusions
The prevalence of fluid retention is high in patients with advanced cancer. BMI and weight loss appear to lose their prognostic significance among them.
