133 Background: Malnutrition, linked to decreased patient tolerance to chemotherapy and increased rates of therapy-related toxicity, negatively affects cancer prognosis. Esophageal carcinomas (EC) frequently present with dysphagia and significant weight loss which may be exacerbated by neoadjuvant chemoradiation, placing EC patients at an increased risk of malnutrition. We therefore aim to assess the prognostic value of pre-operative malnutrition for esophageal cancer patients undergoing neoadjuvant therapy (NAT). Methods: Query of our institution’s IRB approved database of 1113 EC patients (pts) identified 725 individuals who underwent NAT followed by resection from 1994-2018. Seventy-six pts were considered to be at higher nutritional risk during NAT, as indicated by significant weight loss and enteral feeding tube requirement (ETF+), while 644 did not receive pre-operative feeding tube placement (ETF–). Clinicopathologic characteristics, post-operative outcomes, and survival were compared between ETF+ and ETF– using various statistical methods. Results: Of the included pts, 83% were male with a median age of 64.5 (28-86) years. Between ETF+ (n = 76) and ETF– (n = 644), pt characteristics were balanced in terms of initial stage, age, histology and tumor location. A higher percentage of ETF+ pts had > 5% weight loss before NAT (32 vs. 6%; p < .01). ETF+ was associated with a significantly worse median survival (27 vs. 77 m; p < .01), but not with increased post-operative length of hospital stay (p = .69), complications (p = .20) or tumor recurrence (p = .89). Although completion of chemotherapy (p = .46) and radiation (p = .49) were comparable between ETF+ and ETF–, tumor response was worse in the ETF+ group (71 vs. 60% non-complete response; p = .02). Conclusions: Our results suggest that baseline malnutrition is a risk factor for poor survival and negatively impacts the efficacy of neoadjuvant therapy in EC patients. Poor response to NAT in malnourished patients may stem from impaired immune function. Future prospective studies should evaluate other parameters for nutritional assessment to further assess the impact of malnutrition on tumor regression and survival after NAT.

Background Patients undergoing hepatopancreatobiliary (HPB) surgery, such patients with pancreatic, periampullary, and liver cancer, are at high risk for malnutrition. Malnutrition increases surgical complications and reduces overall survival. Despite its severity, there are limited interventions addressing malnutrition after HPB surgery. The aim of this pilot trial was to examine feasibility, acceptability, usability, and preliminary efficacy of a remote nutrition monitoring intervention after HPB surgery. Methods Participants received tailored nutritional counseling before and after surgery at 2 and 4 weeks after hospital discharge. Participants also recorded nutritional intake daily for 30 days, and these data were reviewed remotely by registered dietitians before nutritional counseling visits. Descriptive statistics were used to describe study outcomes. Results All 26 patients approached to participate consented to the trial before HPB surgery. Seven were excluded after consent for failing to meet eligibility criteria (e.g., did not receive surgery). Nineteen participants (52.6% female, median age = 65 years) remained eligible for remote monitoring post-surgery. Nineteen used the mobile app food diary, 79% of participants recorded food intake for greater than 80% of study days, 95% met with the dietitian for all visits, and 89% were highly satisfied with the intervention. Among participants with complete data, the average percent caloric goal obtained was 82.4% (IQR: 21.7). Conclusions This intervention was feasible and acceptable to patients undergoing HPB surgery. Preliminary efficacy data showed most participants were able to meet calorie intake goals. Future studies should examine intervention efficacy in a larger, randomized controlled trial.

Background Malnutrition is under-recognized in cancer patients and can lead to poor treatment outcomes. We aim to develop an outpatient-focused score based on the Malnutrition Screening Tool (MST) to help identify colorectal cancer (CRC) profiles at high risk for malnutrition. Methods 506 CRC patients during initial outpatient oncology consultation at our tertiary referral outpatient oncology clinic completed the MST. Objective and subjective data were collected through chart review. Data gathered are as follows: demographics, anthropometrics, laboratory values, patient-reported symptoms, MST score, cancer history, performance status, socioeconomic status, and Charlson Comorbidity. Predictors of malnutrition were identified by logistic regression. Receiver operating curve (ROC), area under the curve (AUC), and our model’s predictability were determined. Results Significant predictors of malnutrition are as follows: younger age (20-39 vs >40 years) (P = .007), normal-to-low body mass index at presentation (P = .019), Eastern Cooperative Oncology Group classification 2-3 (P = .012), metastatic disease (P = .046), albumin <3.0 g/dL (P = .033), fatigue (P < .001), and change in stool/bowel habits (P = .002). In our derived malnutrition score, risk of malnutrition increased from 11% for score 0, to 100% for scores 9-10. Receiver operating curve showed AUC .745 (95% CI, .697-.793). Discussion An outpatient clinic-derived malnutrition score obtained from objective and patient-reported variables may facilitate identification of CRC patients at highest risk for malnutrition. Rapid identification and intervention in high-risk patients may improve treatment recovery, therapy tolerance, and quality of life. Our tool requires external validation before application in clinical practice.

As surgical and adjuvant therapies for gastrointestinal (GI) cancers improve in safety and efficacy, extended survival in these diseases is becoming commonplace. Surgically induced nutrition alterations are common side effects of treatment and often debilitating. This review is intended for multidisciplinary teams to better understand the postoperative anatomy, physiology, and nutrition morbidity of GI cancer operations. We have arranged this paper by the anatomic and functional changes to the GI tract intrinsic to common cancer operations. Operation-specific long-term nutrition morbidity is detailed, along with the underlying pathophysiology. We have included the most common and effective interventions for the management of individual nutrition morbidities. Finally, we highlight the importance of a multidisciplinary approach to the evaluation and treatment of these patients over the oncologic surveillance period and beyond.
