Conclusions

Sarcopenia and low mean skeletal muscle attenuation are common in women undergoing PDS for advanced EOC. These factors are associated with poorer outcomes, and can be used in preoperative risk stratification and patient counseling. Further research into body composition and whether this risk factor can be altered via nutrition or fitness in this population is warranted.

Sarcopenia (from Greek σάρξ sarx, "flesh" and πενία penia, "poverty") is the degenerative loss of skeletal muscle mass (0.5–1% loss per year after the age of 50), quality, and strength associated with aging.^[1] Sarcopenia is a component of the frailty syndrome. It is often a component of cachexia. It can also exist independently of cachexia; whereas cachexia includes malaise and is secondary to an underlying pathosis (such as cancer), sarcopenia may occur in healthy people and does not necessarily include malaise.
