Objective: Disease-related malnutrition is a debilitating condition frequently observed in patients with cancer. The aim of the current study was to prospectively examine postoperative changes in nutritional and functional status of patients undergoing surgery for gastric, esophageal, and gastroesophageal junction cancer., Methods: Participants were prospectively recruited from September 2015 to September 2019. The assessment of malnutrition was based on the Patient-Generated Subjective Global Assessment tool. The functional assessment included the evaluation of muscle strength and physical performance, while muscle mass assessment was based on Skeletal Muscle Mass Index (SMI) derived from the analysis of computed tomography scans. The follow up of patients was scheduled at six months postoperatively., Results: A total of 98 patients were analyzed. Mean patient age was 60.79 ± 10.19 years and 80.6% were males. The mean unintentional weight loss at 6 months was 11.7 ± 8.0%. Patients who underwent McKeown esophagectomy reported the greatest weight loss postoperatively (16.2 ± 9.6%), whereas the lowest rate of weight loss was observed in patients who underwent partial gastrectomy (5.6 ± 6.7%). The rate of severe malnutrition declined at six months postoperatively (39.7% vs 27%). Muscle strength and physical performance were significantly deteriorated at 6 months postoperatively, except for the group of partial gastrectomy, while SMI significantly decreased in all groups of patients except for McKewon esophagectomy group. Finally, the prevalence of low muscle mass increased significantly from 43.5% in the preoperative period to 66.7% at the follow-up., Conclusions: Our study revealed a significant deterioration in gastroesophageal cancer patient nutritional and functional status at six months postoperatively. The high prevalence of malnutrition and low muscle mass requires systematic follow-up and multidirectional monitoring in order to ensure the successful rehabilitation of these patients.

Oncologic patients often suffer from malnutrition which in turn, might have negative impact on treatment outcomes. The Geriatric Nutritional Risk Index (GNRI), as an index of impaired nutritional status, has emerged as a significant prognostic factor for short-and long-term outcomes in cancer patients. The aim of the current systematic review is to determine whether the GNRI is an independent prognostic factor of postoperative complications and survival in cancer patients. A systematic search was conducted to identify studies, published from 2005 to 2019, which assessed associations between GNRI and short- and long-term outcomes in cancer patients. Eighteen studies fulfilled the eligibility criteria and were included in the analysis. Low scores of GNRI were associated with increased risk for developing postoperative complications and impaired survival of cancer patients in most studies. Our findings support the use of the GNRI in the clinical practice, since it is a simple and reliable tool for assessing nutritional status in oncologic patients. More prospective, multi-centered studies are warranted to confirm the current results, as well as the role of nutritional support in improving the prognosis of cancer patients.

Objective: Malnutrition is common in patients who underwent upper gastrointestinal cancer surgery. Our goal was to explore postoperative compliance with oral nutritional supplementation and define barriers to consumption in patients with esophageal, gastroesophageal junction, and gastric cancer. Methods: Participants were prospectively recruited from September 2015 to November 2018. Preoperative nutritional status was assessed using the Patient Generated Subjective Global Assessment. Malnourished patients and patients at risk for malnutrition were offered oral nutritional supplementation at the time of hospital discharge. Compliance was evaluated 1 month after hospital discharge. Results: A total of 78 patients were analyzed. Mean patient age was 62.8 ± 10.7 years and 83.3% were males. Εsophagectomy and gastrectomy were performed in 60.3% and 39.7% of the patients respectively. Twenty-eight (35.9%) participants reported consuming all prescribed supplements, whereas 50 (64.1%) patients were noncompliant with their prescribed oral nutritional supplementation regimen. The main barriers to oral nutritional supplementation compliance were bloating (compliant vs. noncompliant patients: 17.9% vs. 58%, p  < 0.001), early satiety (compliant vs. noncompliant patients: 25% vs. 52.32%, p  < 0.001), flavor or texture dislike (compliant vs. noncompliant patients: 7.1% vs. 34%, p  < 0.001), and diarrhea (compliant vs. noncompliant patients: 10.7% vs. 24%, p  < 0.001). No other statistically significant differences were identified between the two groups. Conclusions: Postoperative compliance to oral nutritional supplementation is low in patients who underwent upper gastrointestinal cancer surgery. Patient education and support as well as providing a range of oral nutrition supplement flavors, texture, and compositions may be useful in increasing adherence to oral nutritional supplementation regimens.
