Abstract 171P


To evaluate the prognostic value of prognostic nutritional index(PNI)in esophageal cancer patients under minimally invasive esophagectomy (MIE) with peritoneal metastasis.


The clinical and pathological data of 197 patients under MIE with anastomotic leakage from January 2013 to December 2015 were analyzed retrospectively.


PNI was not associated with various clinicopathological factors such as age, gender, smoking history, tumor location, tumor length, differentiation degree, T stage, N stage, treatment mode, TNM stage and lymph node metastasis rate (P > 0.05). Univariate survival analysis showed that male, smoking history, advanced tumor stage, tumor length>5cm, advanced N stage, higher lymph node metastasis rate, advanced TNM stage, and treatment modality were associated with poor prognosis. Multivariate analysis showed that N stage (HR = 6.108, CI:1.614-23.113, P = 0.008) and treatment modality (HR = 0.362, CI: 0.213-0.617, P < 0.001) are independent risk factors. PNI is not an independent risk factor.


Prognostic nutritional index is not an independent risk factor of the prognosis for patients under minimally invasive esophagectomy with anastomotic leakage. Treatment method and lymph node metastasis are still the main factors affecting long-term survival in this group.
