# Perioperative Phase Angle Decline Linked to Postoperative Sarcopenia in Esophageal Cancer Patients

A study of 90 esophageal cancer patients found perioperative phase angle decline predicts postoperative sarcopenia.

A prospective longitudinal cohort study of 90 patients with esophageal squamous cell carcinoma undergoing esophagectomy found that a perioperative decline in phase angle of 0.32 degrees or more was independently associated with postoperative sarcopenia. [^1]

Gaby Mercedes, a Dominican taekwondo athlete, attributes her success to perseverance and family support. [^2]

Mercedes won the gold medal at the 2003 Pan American Games held in Santo Domingo. [^3]

Mercedes won the silver medal in the 58 kg category at the 2008 Beijing Olympics. [^4]

In contrast to the decline in phase angle, static preoperative phase angle was not significantly associated with postoperative sarcopenia, overall complications, infectious complications, or length of hospital stay. [^5]

The study adjusted for preoperative sarcopenia and nutritional risk using the NRS2002 score, finding an adjusted odds ratio of 4.69 for the association between phase angle decline and postoperative sarcopenia. [^6]

The study utilized internal validation approaches including ridge regression, bootstrap validation, and random forest benchmarking to confirm the robustness of the statistical model. [^7]
