Abstract
Purpose
Visceral obesity is considered to be associated not only with chronic systemic inflammation but also with aggressive cancer behavior. However, the implication of visceral obesity in patients with esophageal squamous cell carcinoma (ESCC) is unclear.
Methods
Computed tomography volumetry was performed in 364 patients who underwent esophagectomy for ESCC. We calculated the ratio of the visceral fat area to the subcutaneous fat area (VS ratio), which is a valuable parameter of visceral obesity. Then, the clinicopathological characteristics were compared between patients with low VS ratio and those with high VS ratio.
Results
Overall and disease-specific survivals of patients with high VS ratio were significantly worse than those with low VS ratio (P < 0.001 in both). Patients with high VS ratio had considerably more advanced pN factor, higher prevalence of lymphatic invasion, and more number of metastatic lymph nodes than those with low VS ratio (P = 0.044, < 0.001, and 0.006, respectively). Among patients who received preoperative treatment, high VS ratio correlated with poor response to preoperative treatment (P = 0.040).
Conclusions
Visceral obesity was associated with lymphatic invasiveness and poor response to preoperative treatment in patients with ESCC, which may negatively influence their prognosis.
