Disease specific substrates in cancer cachexia - Reality and anticipation

Effect of Short-Term Preoperative Parenteral Nutrition Support for Gastric Cancer Patients with Sarcopenia: a Propensity Score Matching Analysis

INTRODUCTION

Sarcopenia is well recognized as an unfavorable prognostic marker for gastric cancer (GC) patients. Currently, few nutritional interventions-such as parenteral nutrition-exist for the treatment of patients with sarcopenia. This study aimed to estimate the effectiveness of short-term preoperative parenteral nutrition (PN) in GC patients with sarcopenia.

MATERIALS AND METHODS

We collected data on GC patients with sarcopenia who underwent radical gastrectomy at our hospital from 2010 to 2018. A 1:1 ratio propensity score matching (PSM) was applied to establish the PN and control groups. Data were analyzed using the chi-squared, Mann-Whitney U, and Fisher's exact tests.

RESULTS

In total, 428 patients met the inclusion criteria, and the propensity scores identified 166 matched pairs of patients with sarcopenia. The overall incidence of postoperative complications between both groups was not significantly different (P = 0.728). The PN group had a lower rate of intra-abdominal infection (P = 0.032) and higher hospitalization costs (P < 0.001) than the control group. Multivariate analysis demonstrated that age, Charlson score, and TNM stage were independent risk factors for postoperative complications. Additionally, subgroup analysis revealed that short-term preoperative PN support is associated with decreased postoperative surgical complications in patients with albumin levels < 35 g/L (P = 0.025).

CONCLUSION

Short-term preoperative PN support is not associated with reduction of overall complication rate in patients with GC and sarcopenia. However, those with sarcopenia and hypoalbuminemia benefited from preoperative PN support.

Malnutrition and cachexia in patients with head and neck cancer treated with (chemo)radiotherapy

AIM

To highlight the problems associated with nutrition that occur in patients with squamous cell carcinoma of the head and neck (SCCHN).

BACKGROUND

SCCHN is associated with weight loss before, during and after radiotherapy or concurrent chemoradiotherapy. Because of serious consequences of malnutrition and cachexia on treatment outcome, mortality, morbidity, and quality of life, it is important to identify SCCHN patients with increased risk for the development of malnutrition and cachexia.

MATERIALS AND METHODS

Critical review of the literature.

RESULTS

This review describes pathogenesis, diagnosis and treatment of malnutrition and cancer cachexia. Treatment of malnutrition and cancer cachexia includes nutritional interventions and pharmacological therapy. Advantages and disadvantages of different nutritional interventions and their effect on the nutritional status, quality of life and specific oncological treatment are presented.

CONCLUSIONS

Nutritional management is an essential part of care of these patients, including early screening, assessment of nutritional status and appropriate intervention.
