Enteral Access is not Required for Esophageal Cancer Patients Undergoing Neoadjuvant Therapy

Prognostic impact of shift to low visceral fat mass after neoadjuvant chemotherapy in patients with esophageal cancer

BACKGROUND

Based on the JCOG1109 trial, it is suggested that the combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) could potentially become a standard neoadjuvant chemotherapy regimen, alongside the conventional 5-fluorouracil and cisplatin (CF) therapy, for esophageal cancer. However, there are few reports on the impact of body composition changes associated with neoadjuvant chemotherapy on prognosis.

AIM

Our study aimed to explore the effect of different neoadjuvant chemotherapy regimens on body composition during treatment and the impacts of body composition changes on their prognosis.

METHODS AND RESULTS

This is a retrospective study of 215 patients with advanced thoracic esophageal cancer who had surgery after neoadjuvant chemotherapy from 2013 to 2019. Computed tomography scans were performed before and after neoadjuvant chemotherapy to assess body composition. Skeletal muscle mass index (SMI) was calculated by dividing total skeletal muscle mass at the 3rd lumbar level by the square of height, while visceral and subcutaneous fat masses were measured at the level of umbilicus. Patients in the lowest 25% of both sexes were classified into the low visceral fat and low subcutaneous fat groups, respectively. Of the patients enrolled, 178 were male and 37 were female. Among them, 91 had clinical Stage II disease, and 124 had clinical Stage III disease. Additionally, 146 patients received neoadjuvant chemotherapy CF, and 69 received neoadjuvant chemotherapy DCF. Comparing the DCF and CF groups, the DCF group consisted of significantly younger patients (p < .01), a higher proportion of males (p = .03), and a greater number of clinical Stage III cases (p < .01). However, although percent change in SMI and visceral fat mass was not significantly different between two regimens, percent change in subcutaneous fat mass was significant in the DCF group. The major prognostic factors for patients undergoing surgery after neoadjuvant chemotherapy for thoracic esophageal cancer were clinical Stage III, transition to low visceral fat, and response rating (SD/PD), while the specific neoadjuvant chemotherapy regimen did not significantly influence the outcomes.

CONCLUSION

This study suggests that prevention of the shift to low visceral fat throughout the neoadjuvant chemotherapy process should improve patient outcomes.

Long-term nutrition in patients candidate to neoadjuvant and adjuvant treatments

To improve outcomes, to decrease the rate of local recurrence and development of distant metastases neoadjuvant and adjuvant therapies are employed in cancer patients in forms of radiation, chemo-, endocrine-, targeted-, and immunotherapy or their combination. Nutrition therapy plays important role in all phases of the cancer journey. From neoadjuvant therapy to prehabilitation, early postoperative nutrition, and long-term nutrition care during the adjuvant phase and survivorship determines the survival and quality of life of cancer patients. During the neoadjuvant phase patients may be in poor nutritional condition which can be aggravated by the applied oncological treatment. Beside this apparent threat this period also gives an excellent opportunity to maintain or even improve the nutritional status of the patients by nutrition therapy. After surgery the burdening effects of the operation may jeopardize the execution of adjuvant therapy. After early postoperative feeding a long-term nutrition strategy should be developed for cancer patients in order to avoid nutritional deterioration during the usually lengthy postoperative therapy. In this narrative review we discuss how preoperative nutritional status and medical nutrition therapy influence the results of surgery and after the operation what is the available evidence about nutritional status and outcome and the potentials to influence them by nutrition therapy.

Enhanced Recovery After Major Gastrectomy for Cancer

Enhanced recovery after surgery (ERAS) protocols have gained increasing popularity over the past 10 years, and its overarching objectives are to improve perioperative morbidity and reduce postoperative length of stay. Consensus guidelines from the ERAS Society specific to major gastrectomy were published in 2014, however since that time, prospective and retrospective studies have expanded the collective evidence for both the content and efficacy of ERAS pathways for gastrectomy. This objective of this review was to summarize recent data pertinent to the preoperative, perioperative, and postoperative management of gastrectomy patients along an ERAS pathway.

Role of dietitian support in improving weight loss and nutrition impact symptoms after oesophageal cancer surgery

BACKGROUND

Oesophageal cancer is frequently accompanied with malnutrition. We aimed to evaluate if early support from dietitians and patient's level of satisfaction with the support from dietitians are associated with better outcomes for weight loss and nutrition impact symptoms (NIS).

METHODS

A nationwide and prospective cohort study on patients operated for oesophageal cancer in Sweden from 2013 onwards, included one year after surgery. Study exposures were (1) preoperative dietitian support (yes vs no) and, (2) patient reported satisfaction with dietitian support (high vs low) and outcomes were postoperative (1) percentage weight loss and (2) NIS score (range 0-24); one year after surgery. An ANCOVA model adjusted for predefined confounders was used and presented as mean differences (MD) with 95% confidence intervals (CI).

RESULTS

Among 245 patients, as many as 57% had received preoperative dietitian support. Preoperative dietitian support was not associated with statistically significant differences in mean postoperative weight loss (MD 0.2 [95% CI -2.6 to 2.9]) and mean NIS score (MD 0.1 [95% CI: -0.8 to 1.0]). Likewise, satisfaction with the dietitian support was not associated with significant differences in mean postoperative weight loss (MD 1.4 [95% CI: -1.5 to 4.3]) and NIS score (MD -0.1 [95% CI: -1 to 0.8]).

CONCLUSIONS

Long-term postoperative weight loss and NIS were not influenced based on whether dietitian support was initiated preoperatively or not and patient's satisfaction level with dietitian support. Similarity in results may reflect effective screening of malnutrition and dietitian support in centres treating oesophageal cancer in Sweden.

Review of Current Machine Perfusion Therapeutics for Organ Preservation

Because of the high demand of organs, the usage of marginal grafts has increased. These marginal organs have a higher risk of developing ischemia-reperfusion injury, which can lead to posttransplant complications. Ex situ machine perfusion (MP), compared with the traditional static cold storage, may better protect these organs from ischemia-reperfusion injury. In addition, MP can also act as a platform for dynamic administration of pharmacological agents or gene therapy to further improve transplant outcomes. Numerous therapeutic agents have been studied under both hypothermic (1-8°C) and normothermic settings. Here, we review all the therapeutics used during MP in different organ systems (lung, liver, kidney, heart). The major categories of therapeutic agents include vasodilators, mesenchymal stem cells, antiinflammatory agents, antiinfection agents, siRNA, and defatting agents. Numerous animal and clinical studies have examined MP therapeutic agents, some of which have even led to the successful reconditioning of discarded grafts. More clinical studies, especially randomized controlled trials, will need to be conducted in the future to solidify these promising results and to define the role of MP therapeutic agents in solid organ transplantation.

Enteral Feeding Access Has an Impact on Outcomes for Patients with Esophageal Cancer Undergoing Esophagectomy: An Analysis of SEER-Medicare

BACKGROUND

Optimal nutrition after esophagectomy is challenging due to alterations in eating, both from the tumor and during surgical recovery. Enteral nutrition via feeding tube is commonly used. The impact of feeding tubes on post-esophagectomy outcomes was examined in a large national data set.

METHODS

Patients with esophageal cancer (1998-2013) undergoing esophagectomy were extracted from the Surveillance Epidemiology and End Results-Medicare database. Chi-square and t tests were used to compare categorical and continuous variables. Time trend analyses were performed with Cochran-Armitage survival using log-rank and multivariable analysis with generalized linear modeling.

RESULTS

The study examined 2495 patients. The majority had enteral feeding access (71%, n = 1794) during the perioperative period. Mortality among the patients with feeding tubes was lower at 30 days (5.4% vs 8.4%), 60 days (9.0% vs 13.0%), and 90 days (12.2% vs 15.8%). In the multivariable analysis, the patients with feeding tubes had improved short-term survival at 30 days (odds ratio [OR], 0.65, 95% confidence interval [CI], 0.46-0.93), 60 days (OR, 0.64; 95% CI, 0.49-0.85), and 90 days (OR, 0.70; 95% CI, 0.54-0.90). The hospital stay was shorter for the patients undergoing enteral feeding tube placement (17.9 vs 19.5 days; p = 0.04). Discharge destination (home vs health care facility) showed no difference.

CONCLUSIONS

Feeding tubes in patients undergoing esophagectomy were associated with an increase in short-term survival up to 90 days after surgery. Feeding tube placement was not associated with higher rates of non-home discharges and did not prolong the hospital stay.

Enteral nutrition and quality of life in patients undergoing chemoradiotherapy for esophageal carcinoma: a comparison of nasogastric tube, esophageal stent, and ostomy tube feeding

BACKGROUND AND AIMS

This study prospectively recruited esophageal squamous cell carcinoma patients who received esophageal stent, nasogastric tube (NGT), or jejunostomy/gastrostomy feeding to compare the changes in nutritional status and quality of life during chemoradiation therapy (CRT).

METHODS

In total, 81 patients were analyzed (stent, 7; surgical ostomy, 26; NGT, 19; oral intake, 29). An NGT was inserted when, despite medication, dysphagia or pain worsened with oral feeding during CRT. Serial body weight and daily narcotic demand were recorded. Changes in serum albumin level and quality of life were also assessed. In subgroup analysis comparing NGT and prophylactic surgical ostomy feeding, 5 patients with total occlusion in the ostomy group were excluded.

RESULTS

Patients in all groups had similar decreases in mean body weight with an overall change of -6.41% ± 5.21% at the end of CRT. The stent group had significantly worse pain, decreased albumin (-1.03 ± .9 mg/dL), and decreased quality of life across CRT compared with the other groups. In subgroup analysis the stent group had significantly higher weight loss, whereas the NGT group had higher narcotic demand and slightly worse quality of life. Two patients (7.7%) had ileus days after jejunostomy creation. Five patients (23.8%) among those received prophylactic ostomy creation and scarcely used it.

CONCLUSIONS

These preliminary results raise concerns that use of esophageal stents may be less suitable in patients undergoing CRT. Tube feeding by means of transnasal or percutaneous routes appear to be comparably effective during CRT, but both have advantages and disadvantages. We suggest a careful endoscopic evaluation to select the population more appropriate for NGT feeding on an as-needed basis during CRT.

Benefits of Supplemental Jejunostomy Tube Feeding During Neoadjuvant Therapy in Patients with Locally Advanced, Potentially Resectable Esophageal Cancer

BACKGROUND

Standard treatment for locally advanced esophageal cancer includes neoadjuvant therapy followed by surgical resection. However, many patients experience a period of decreased oral intake during neoadjuvant treatment and are at risk for malnutrition. We hypothesize that use of jejunostomy tube (j-tube) feedings during neoadjuvant therapy in selected patients may be associated with better perioperative outcomes.

METHODS

A prospectively collected database at a single institution was retrospectively analyzed. The study period was from 2005 to 2015. Patients who underwent j-tube placement before neoadjuvant therapy before definitive resection for esophageal cancer were included in the analysis. Perioperative outcomes were compared between patients who adhered to recommended tube feeds during neoadjuvant therapy (users) and patients who did not adhere (nonusers).

RESULTS

During the study period, 94/301 patients received a j-tube before or during neoadjuvant therapy for esophageal cancer. Seventy-three patients utilized tube feeds regularly during the neoadjuvant phase, while 21 patients did not. The groups did not differ significantly with respect to clinical factors such as dysphagia on presentation, postneoadjuvant therapy performance status, or Charlson Comorbidity Index. Perioperative pneumonia rates were lower in j-tube users compared to nonusers (6.8% [5 of 73] versus 23.8% [5 of 21]), respectively, P = .036); this difference remained significant with adjustment for type of surgery (odds ratio = 0.16, P = .018).

CONCLUSIONS

j-Tube users had a significantly lower incidence of pneumonia within 30 days of curative resection when compared to nonusers. j-Tube feedings during neoadjuvant therapy for selected patients with locally advanced esophageal cancer should be encouraged.
