Sarcopenia obesity associated with reduced overall survival and quality of life among cancer patients:JAMA

The results showed that a total of 6790 patients participated in the study, with a mean (SD) age of 59.64 (10.77) years and 3489 were female (51.4%). The prevalence of SO was 4.36% (296 out of 6790) across the entire cohort and 14.98% (296 out of 1976) among those classified with obesity. SO prevalence rose with advancing age. Over a median (IQR) follow-up period of 6.83 (5.67-7.04) years, a total of 2103 patients passed away. Cox regression analysis revealed that SO independently correlated with decreased OS, observed consistently in both men and women. SO was also linked to diminished QoL and an increased risk of ICU admission. Among the diagnostic criteria for SO, low hand grip strength (HGS) was observed as the sole component associated with poorer OS.

Among the patients with solid tumors, sarcopenic obesity which was defined by ESPEN-EASO criteria, was present in 4.36% of the entire cohort and 14.98% of the individuals with obesity. Increased prevalence rates were observed among patients with breast, lung and colorectal cancers. SO expressed significant associations with quality of life, ICU admission rates and overall survival in cancer patients. Regular screening and diagnosis for SO are recommended for individuals with cancer and the ESPEN-EASO algorithm appears promising for clinical implementation in managing SO.
