Abstract
Background
Preoperative weight loss in esophageal cancer is reported to be associated with a poor prognosis. However, the impact of postoperative weight loss on the prognosis of patients with esophageal cancer remains unclear.
Methods
This study included 186 patients with esophageal squamous cell carcinoma who underwent surgery between January 2012 and January 2015. The relationship between weight loss 6 months after esophagectomy as well as the clinical factors and prognosis of patients was investigated.
Results
The mean weight loss rate for all the patients was 9.3% at 3 months, 10.8% at 6 months, 11.1% at 12 months, and 11.4% at 24 months after surgery. The patients with severe weight loss 6 months after surgery (≥ 12%) exhibited lower serum albumin levels and a lower prognostic nutrition index 6 months after esophagectomy than the patients with moderate weight loss (< 12%; p = 0.011 and 0.009, respectively). Although overall survival did not differ significantly between the two groups, for all the patients, severe weight loss was significantly associated with shortened overall survival for the cStages 3 and 4 patients (3-year overall survival rate, 76.6% in the moderate group vs 54.5% in the severe group; p = 0.042). The multivariate analyses identified only severe weight loss as an independent factor associated with worse overall survival for the cStages 3 and 4 patients (p = 0.034).
Conclusion
This study showed that postoperative weight loss negatively affected the prognosis for patients with advanced esophageal cancer, indicating the necessity of administering nutritional interventions to these patients to prevent postoperative weight loss.
