[Enteral nutrition support reduces toxicity of chemotherapy in patients with advanced or metastatic esophageal cancer].

Abstract

OBJECTIVE:

To assess the impact of enteral nutrition support on response and toxicity of the first-line chemotherapy in those patients with advanced or metastatic esophageal cancer.

METHODS:

We collected the clinical data of 118 patients with unresectable advanced or metastatic esophageal cancer who received the first-line chemotherapy in our center from July 2014 to December 2016. All these 118 esophageal cancer patients were then divided into two groups: the nutrition group (received enteral nutrition support in addition to chemotherapy) and the control group (received chemotherapy only). Differences were analyzed before and after chemotherapy in each of the nutritional indicators including Karnofsky performance status (KPS), weight, body mass index (BMI), hemoglobin (Hb), number of lymphocytes (Lymph), total protein (TP), albumin (Alb), triglycerides (TG), total cholesterol (TC) in both groups. And differences of the efficacy and toxicities of the first-line chemotherapy between the two groups were also analyzed.

RESULTS:

(1) Weight, BMI and Hb were all significantly decreased after chemotherapy in the control group (P<0.001), while there was no significant change of weight and BMI in the nutrition group, just with Hb decrease only. However, there was no significant change of all the other nutrition indicators after chemotherapy in both groups. (2) Compared with the control group, the nutrition group had significantly lower incidence of grade 3 to 4 hematologic toxicities after chemotherapy (15.4% vs. 42.1%, P=0.004). In addition, the incidence of grade 3 to 4 nonhematologic toxicities after chemotherapy was also lower in the nutrition group but without statistical significance (0 vs. 9.2%, P=0.123). Logistic regression model was then used for multivariate analysis to identify the factors that affected the toxicity of chemotherapy in these patients, and the results showed that nutrition therapy was an independent influencing factor of grade 3 or higher hematological toxicity after chemotherapy in the patients with esophageal cancer (P=0.008, RR=6.048, 95%CI: 1.589-23.027). (3) The response rate of chemotherapy between the control group and the nutrition group had not significant difference.

CONCLUSION:

Enteral nutrition support in addition to chemotherapy could improve nutrition status and reduce toxicity of chemotherapy in advanced or metastatic esophageal cancer patients.
