Actual Sarcopenia Reflects Poor Prognosis in Patients with Esophageal Cancer.

Abstract

BACKGROUND:

Minimally invasive esophagectomy (MIE) for esophageal cancer patients with sarcopenia is associated with a high risk of perioperative complications; however, the relationship between sarcopenia and the survival of esophageal cancer patients remains controversial. In this study, we aimed to develop a stratifying marker for sarcopenia to precisely predict patients' prognosis.

METHODS:

We retrospectively studied 135 patients who underwent thoracoscopic esophagectomy at Kobe University Hospital from 2011 to 2015 and who were preoperatively diagnosed with or without sarcopenia based on the Asian Working Group for Sarcopenia index. Creatinine levels and albumin as measures of skeletal muscle volume and nutritional status, respectively, were used to develop a marker to be used for stratifying sarcopenic patients based on prognosis.

RESULTS:

Of the 135 patients, 35 were diagnosed with sarcopenia and 100 were not. We combined the creatinine and albumin levels (Cr × Alb) as a stratifying marker for sarcopenia, and extracted sarcopenic patients with values below the Cr × Alb cut-off as the actual sarcopenic group. The 5-year overall survival (OS) rates of the actual and non-actual sarcopenic groups were 28.9% and 58.9%, respectively (p = 0.0005), and the 5-year disease-free survival rate of the actual sarcopenic group was 34.1%, and 62.8% (p = 0.0106) for the non-actual sarcopenic group. This stratified sarcopenia model was an independent prognostic factor and was superior to sarcopenia alone for OS.

CONCLUSIONS:

In patients undergoing MIE, preoperative measurement of Cr × Alb may be a prognostic stratification marker for patients with sarcopenia.
