Preoperative nutritional optimization of esophageal cancer patients

Developing sarcopenia during neoadjuvant therapy is associated with worse survival in esophageal adenocarcinoma patients

BACKGROUND

Sarcopenia in cancer patients has been associated with mixed postoperative outcomes. The aim of this study was to evaluate whether the development of sarcopenia during the neoadjuvant period is predictive of postoperative mortality in esophageal adenocarcinoma patients.

METHODS

We queried a prospective database to retrieve the sarcopenic status of patients with esophageal adenocarcinoma who underwent cross-sectional imaging of the third lumbar vertebra at diagnosis and within 2 months of undergoing an esophagogastrectomy between 2014 and 2022.

RESULTS

Of the 71 patients included in the study, 36 (50.7%) presented with sarcopenia at diagnosis. Of the 35 non-sarcopenic patients, 14 (40%) developed sarcopenia during the neo-adjuvant period. Patients who were not sarcopenic at diagnosis but developed sarcopenia preoperatively had significantly worse overall survival than patients sarcopenic at diagnosis and not sarcopenic preoperatively and patients experiencing no change in sarcopenic status (median 18 vs 47 vs 31 months; P = .02). Diagnostic and preoperative sarcopenic status alone were not significantly associated with overall survival (P = .48 and P = .56, respectively). Although 37 (52.1%) patients died, the cause of death was often not cancer-related (54.1%) and included acute respiratory failure, pneumonia, and cardiac arrest. No significant survival difference was observed when stratified by >10% weight loss (P = .9) or large loss in body mass index (P = .8).

CONCLUSION

Developing sarcopenia during the neo-adjuvant period may be associated with worse overall survival in patients requiring esophagogastrectomy.

A systematic review of oncosurgical and quality of life outcomes following pelvic exenteration for locally advanced and recurrent rectal cancer

INTRODUCTION

Pelvic exenteration (PE) is now the standard of care for locally advanced (LARC) and locally recurrent (LRRC) rectal cancer. Reports of the significant short-term morbidity and survival advantage conferred by R0 resection are well established. However, longer-term outcomes are rarely addressed. This systematic review focuses on long-term oncosurgical and quality of life (QoL) outcomes following PE for rectal cancer.

METHODS

A systematic review of the PubMed®, Cochrane Library, MEDLINE® and Embase® databases was conducted, in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Studies were included if they reported long-term outcomes following PE for LARC or LRRC. Studies with fewer than 20 patients were excluded.

FINDINGS

A total of 25 papers reported outcomes for 5,489 patients. Of these, 4,744 underwent PE for LARC (57.5%) or LRRC (42.5%). R0 resection rates ranged from 23.2% to 98.4% and from 14.9% to 77.8% respectively. The overall morbidity rates were 17.8-87.0%. The median survival ranged from 12.5 to 140.0 months. None of these studies reported functional outcomes and only four studies reported QoL outcomes. Numerous different metrics and timepoints were utilised, with QoL scores frequently returning to baseline by 12 months.

CONCLUSIONS

This review demonstrates that PE is safe, with a good prospect of R0 resection and acceptable mortality rates in selected patients. Morbidity rates remain high, highlighting the importance of shared decision making with patients. Longer-term oncological outcomes as well as QoL and functional outcomes need to be addressed in future studies. Development of a core outcomes set would facilitate better reporting in this complex and challenging patient group.

A nomogram based on clinical characteristics and nutritional indicators for relative and absolute weight loss during radiotherapy in initially inoperable patients with locally advanced esophageal squamous cell carcinoma

OBJECTIVE

Radiation for locally advanced esophageal squamous cell carcinoma often is accompanied by radiation esophagitis, which interferes with oral intake. We aimed to develop a nomogram model to identify initially inoperable patients with relative and absolute weight loss who need prophylactic nutritional supplementation.

METHODS

A total of 365 initially inoperable patients with locally advanced esophageal squamous cell carcinoma receiving radiotherapy between January 2018 and December 2022 were included in the study, which was divided into discovery and validation cohorts. Receiver operating characteristic and Kaplan-Meier curve analyses were performed to compare the areas under the curve and survival benefits.

RESULTS

A total of 42.2% (154 of 365) of the patients had been diagnosed with cancer cachexia. The malnourished group had a higher interruption rate of radiotherapy and number of complication diseases (P < 0.05). Meanwhile, patients with malnutrition had lower lymphocytes and prognostic nutritional index (P < 0.05). The combined index showed a higher area under the curve value (0.67; P < 0.001) than number of complication diseases (area under the curve = 0.52) and prognostic nutritional index (area under the curve = 0.49) for relative weight loss (≥ 5%). Similarly, the combined index had a higher area under the curve value (0.79; P < 0.001) than number of complication diseases (area under the curve = 0.56), treatment regimens (area under the curve = 0.56), subcutaneous fat thickness (area under the curve = 0.60), pretreatment body weight (area under the curve = 0.61), neutrophils (area under the curve = 0.56), and prognostic nutritional index (area under the curve = 0.50) for absolute weight loss (≥ 5 kg). Absolute and relative weight loss remained independent prognostic factors, with short overall survival rates compared with the normal group (P < 0.05). Patients with high nomogram scores supported by nutritional intervention had less weight loss, better nutrition scores, and increased plasma CD8+ T cells, and interferon gamma.

CONCLUSIONS

We developed a nomogram model that was intended to estimate relative and absolute weight loss in initially inoperable patients with locally advanced esophageal squamous cell carcinoma during radiotherapy, which might help facilitate an objective decision on prophylactic nutritional supplementation.

Effect of percutaneous endoscopic gastrostomy prior to oesophageal cancer surgery on postoperative wound complications in patients: A meta-analysis

It is still a matter of controversy whether percutaneous endoscopic gastrostomy(PEG) should be used prior to the operation for the purpose of feeding the patient with resectable oesophageal carcinoma (EC). Comparison was made between EC and preoperatively treated PEG and non-preoperative PEG. An extensive literature review has been conducted to determine the results about PEG and No-PEG trials. In this paper, we chose 4 papers out of 407 of them through a strict selection process. In this trial, there were 1027 surgical cases of oesophagus carcinoma, 152 with PEG pre-surgery and 875 without PEG. The total sample size ranged from 14 to 657. Two studies showed that there was no statistically significant difference in the occurrence of postoperative wound infection among PEG and No-PEG(OR, 1.03; 95% CI, 0.38, 2.80 p = 0.96), there was no statistical significance in the likelihood of anastomotic leak among PEG after surgery compared to No-PEG in 4 trials (OR, 1.13; 95% CI, 0.62-2.07 p = 0.69), and there were no statistical differences between PEG and No-PEG before operation on anastomotic stricture for esophagectomy(OR, 0.70; 95% CI, 0.31-1.56 p = 0.38). No wound or anastomosis complications were observed in the PEG group. Thus, PEG preoperatively is an effective and safe procedure without any harmful influence on gastrointestinal structure or anastomosing. It can be applied to patients with oesophagus carcinoma who have a high risk of undernutrition. Nevertheless, because of the limited number of randomized controlled trials in this meta-analysis, caution should be exercised in their treatment. More high-quality research involving a large sample is required to confirm the findings.

Long-Term Survival Associated with Direct Oral Feeding Following Minimally Invasive Esophagectomy: Results from a Randomized Controlled Trial (NUTRIENT II)

Advancements in perioperative care have improved postoperative morbidity and recovery after esophagectomy. The direct start of oral intake can also enhance short-term outcomes following minimally invasive Ivor Lewis esophagectomy (MIE-IL). Subsequently, short-term outcomes may affect long-term survival. This planned sub-study of the NUTRIENT II trial, a multicenter randomized controlled trial, investigated the long-term survival of direct versus delayed oral feeding following MIE-IL. The outcomes included 3- and 5-year overall survival (OS) and disease-free survival (DFS), and the influence of complications and caloric intake on OS. After excluding cases of 90-day mortality, 145 participants were analyzed. Of these, 63 patients (43.4%) received direct oral feeding. At 3 years, OS was significantly better in the direct oral feeding group (p = 0.027), but not at 5 years (p = 0.115). Moreover, 5-year DFS was significantly better in the direct oral feeding group (p = 0.047) and a trend towards improved DFS was shown at 3 years (p = 0.079). Postoperative complications and caloric intake on day 5 did not impact OS. The results of this study show a tendency of improved 3-year OS and 5-year DFS, suggesting a potential long-term survival benefit in patients receiving direct oral feeding after esophagectomy. However, the findings should be further explored in larger future trials.

Impact of body composition and physical strength changes during chemoradiotherapy on complications and survival after oesophagectomy

BACKGROUND

The aim of this study was to assess body composition and physical strength changes during neoadjuvant chemoradiotherapy (nCRT) and assess their predictive value for (severe) postoperative complications and overall survival in patients who underwent oesophagectomy for oesophageal cancer.

METHODS

Consecutive patients who underwent nCRT and oesophagectomy with curative intent in a tertiary referral center were included in the study. Perioperative data were collected in a prospectively maintained database. The CT images before and after nCRT were used to assess skeletal muscle index (SMI), subcutaneous fat index (SFI), and visceral fat index (VFI). To assess physical strength, handgrip strength (HGS) and the exercise capacity of the steep ramp test (SRT Wpeak) were acquired before and after nCRT.

RESULTS

Between 2015 and 2020, 126 patients were included. SMI increased in female subgroups and decreased in male subgroups (35.38 to35.60 cm2/m2 for females, P value 0.048, 46.89 to 45.34 cm2/m2 for males, P value < 0.001). No significant changes in SFI, VFI, HGS, and SRT Wpeak were observed. No predictive value of changes in SMI, HGS, and SRT Wpeak was shown for (severe) postoperative complications and overall survival.

CONCLUSIONS

A significant but minimal decrease in SMI during nCRT was observed for males only, it was not associated with postoperative complications or overall survival. Physical strength measurements did not decrease significantly over the course of nCRT. No associations with postoperative complications or overall survival were observed.

Pattern of Aorto-coeliac Calcification Correlating Cervical Esophago-gastric Anastomotic Leak After Esophagectomy for Cancer: a Retrospective Study

PURPOSE

Cervical esophagogastric anastomotic leak (CEGAL) is a troublesome complication after esophagectomy and gastric pull-up. The aim of the study was to identify the preoperative clinical and radiological factors associated with increased risk of CEGAL.

METHODS

Consecutive patients whose clinical and imaging data were available and who underwent cervical esophago-gastric anastomosis following esophagectomy and gastric pull-up for esophageal cancer, between January 2013 and January 2021, were included. The patient details were collected from a prospectively maintained database. The demographic, clinical, and laboratory data including preoperative hemoglobin and serum albumin levels were recorded. Preoperative computed tomographic (CT) images were reviewed by two independent radiologists to assign vascular calcification scores for proximal aorta, distal aorta, aortic bifurcation, celiac trunk, and celiac artery branches. The primary outcome evaluated was clinically evident neck leak. Univariate and multivariate analysis of the clinical and radiological factors was performed to identify significant predictors.

RESULTS

A total of 100 patients (mean age: 54.7 years; 60 males, 40 females) were included in the study and of them, 27 developed CEGAL. Compared to the group without CEGAL, the patient group with CEGAL had significantly higher mean age (60.3 vs. 52.7 years, p < 0.01), and higher incidences of diabetes mellitus (25.9% vs 10.9%, p = 0.03), major proximal aortic calcification (29.6% vs. 6.3%, p < 0.01), and major celiac trunk calcification (22.2% vs. 6.3%, p = 0.02). Multivariate regression analysis identified age and presence of major proximal aortic calcification as independent risk factors for the development of CEGAL.

CONCLUSION

Major calcification of the proximal aorta and advanced age are independent risk factors for CEGAL after esophagectomy.

The impact of sarcopenia on esophagectomy for cancer: a systematic review and meta-analysis

BACKGROUND

Esophagectomy is the gold-standard treatment for locally advanced esophageal cancer but has high morbimortality rates. Sarcopenia is a common comorbidity in cancer patients. The exact burden of sarcopenia in esophagectomy outcomes remains unclear. Therefore, this systematic review and meta-analysis were performed to establish the impact of sarcopenia on postoperative outcomes of esophagectomy for cancer.

METHODS

We performed a systematic review and meta-analysis comparing sarcopenic with non-sarcopenic patients before esophagectomy for cancer (Registration number: CRD42021270332). An electronic search was conducted on Embase, PubMed, Cochrane, and LILACS, alongside a manual search of the references. The inclusion criteria were cohorts, case series, and clinical trials; adult patients; studies evaluating patients with sarcopenia undergoing esophagectomy or gastroesophagectomy for cancer; and studies that analyze relevant outcomes. The exclusion criteria were letters, editorials, congress abstracts, case reports, reviews, cross-sectional studies, patients undergoing surgery for benign conditions, and animal studies. The meta-analysis was synthesized with forest plots.

RESULTS

The meta-analysis included 40 studies. Sarcopenia was significantly associated with increased postoperative complications (RD: 0.08; 95% CI: 0.02 to 0.14), severe complications (RD: 0.11; 95% CI: 0.04 to 0.19), and pneumonia (RD: 0.13; 95% CI: 0.09 to 0.18). Patients with sarcopenia had a lower probability of survival at a 3-year follow-up (RD: -0.16; 95% CI: -0.23 to -0.10).

CONCLUSION

Preoperative sarcopenia imposes a higher risk for overall complications and severe complications. Besides, patients with sarcopenia had a lower chance of long-term survival.

Immunonutrition in Radical Cystectomy: State of the Art and Perspectives

Preoperative nutritional status is a pivotal aspect to consider in patients with cancer undergoing radical cystectomy (RC), as those at risk of malnutrition or already malnourished are more prone to post-surgical complications. The loss of muscle mass is a major consequence of cancer-related malnutrition. It is associated with increased risk of hospital readmission, longer hospitalization, and higher mortality. Nowadays, the close relationship between nutritional and immunological aspects under stressful conditions, such as surgery, represents an emerging scientific and clinical issue. Indeed, the synergistic action of reduced food intake and systemic inflammation generates metabolic derangements with tissue catabolism, including skeletal muscle breakdown, which is, in turn, associated with immune system dysfunction. In order to offer an additional immune-nutritional boost to the post-surgical phase, particularly in malnourished patients, nutritional support may include oral nutritional supplements and/or enteral formulas enriched with specific nutrients such as omega-3 fatty acids, arginine, glutamine, and nucleotides, with acknowledged immune-modulating effects. In the present narrative review, we addressed the state of the art of the available scientific literature on the benefit of immunonutrition in patients undergoing RC for cancer and suggest possible future perspectives to be explored. Although the role of immunonutrition was found to be little explored in the context of urologic oncology, the preliminary available data on radical cystectomy, summarized in the present paper, are promising and suggest that it may improve postoperative outcomes through immunomodulation, regardless of nutritional status before surgery.

Gastro-Intestinal Disorders and Micronutrient Deficiencies following Oncologic Esophagectomy and Gastrectomy

Primary surgical indications for the esophagus and stomach mainly involve cancer surgeries. In recent years, significant progress has been made in the field of esogastric surgery, driven by advancements in surgical techniques and improvements in perioperative care. The rate of resectability has increased, and surgical strategies have evolved to encompass a broader patient population. However, despite a reduction in postoperative mortality and morbidity, malnutrition remains a significant challenge after surgery, leading to weight loss, muscle mass reduction, and deficiencies in essential nutrients due to digestive complications. Malnutrition worsens quality of life and increases the risk of tumor recurrence, significantly affecting prognosis. Nevertheless, the nutritional consequences following surgery are frequently overlooked, mainly due to a lack of awareness regarding their long-term effects on patients who have undergone digestive surgery, extending beyond six months. Micronutrient deficiencies are frequently observed following both partial and total gastrectomy, as anticipated. Surprisingly, these deficiencies appear to be similarly prevalent in patients who have undergone esophagectomy with iron, vitamins A, B1, B12, D, and E deficiencies commonly observed in up to 78.3% of the patients. Recognizing the distinct consequences associated with each type of intervention underscores the importance of implementing preventive measures, early detection, and prompt management.

The Impact of Pretreatment Esophageal Stenosis on Survival of Esophageal Cancer Patients

BACKGROUND

Little is known about the survival impacts of pretreatment cancerous stenosis on patients with esophageal carcinoma (EC).

METHODS

The clinicopathologic characteristics of patients who underwent surgery for EC between January 2010 and December 2018 were retrospectively reviewed. Esophageal stenosis was defined as present when a thin endoscope could not be passed through the tumor site. The impacts of stenosis on overall survival (OS) and cancer-specific survival (CSS) were evaluated using Cox hazards analysis.

RESULTS

Of the 496 EC patients in this study, 51 (10.3 %) had pretreatment esophageal stenosis. Stenosis was associated with lower body mass index (P < 0.001) and higher pStage (P < 0.001). The 3-year OS rate for the patients with stenosis was significantly poorer than for the patients without stenosis (40.2 % vs 69.6 %; hazard ratio [HR], 2.19; P < 0.001). The survival outcomes, especially CSS, for the patients with stenosis were significantly poorer than for the patients without stenosis for both pStage II-III (P = 0.009) and pStage IV (P = 0.006) disease. The OS and CSS curves were well stratified by the presence of stenosis even in early-stage (pStage II) patients (P = 0.04 and P < 0.01, respectively). Multivariable analysis showed esophageal stenosis, pStage III-IV disease, and non-curative resection to be independently associated with poor OS (HR, 1.61; P = 0.02) and poor CSS (HR,1.67; P = 0.02). Higher pStage was an independent predictor of poor CSS for patients without stenosis, but not for those with stenosis.

CONCLUSIONS

Esophageal carcinoma patients with pretreatment stenosis had significantly poorer survival outcomes, especially poorer CSS, than those without stenosis in both early- and advanced-stage diseases.

Impact of Body Mass Index on Major Complications, Multiple Complications, In-hospital Mortality, and Failure to Rescue After Esophagectomy for Esophageal Cancer: A Nationwide Inpatient Database Study in Japan

OBJECTIVE

To examine the association of BMI with mortality and related outcomes after oncologic esophagectomy.

SUMMARY BACKGROUND DATA

Previous studies showed that high BMI was a risk factor for anastomotic leakage and low BMI was a risk factor for respiratory complications after esophagectomy. However, the association between BMI and in-hospital mortality after oncologic esophagectomy remains unclear.

METHODS

Data for patients who underwent esophagectomy for esophageal cancer between July 2010 and March 2019 were extracted from a Japanese nationwide inpatient database. Multivariate regression analyses and restricted cubic spline analyses were used to investigate the associations between BMI and short-term outcomes, adjusting for potential confounders.

RESULTS

Among 39,406 eligible patients, in-hospital mortality, major complications, and multiple complications (≥2 major complications) occurred in 1069 (2.7%), 14,824 (37.6%), and 3621 (9.2%), respectively. Compared with normal weight (18.5-22.9 kg/m 2 ), severe underweight (<16.0 kg/m 2 ), mild/moderate underweight (16.0-18.4 kg/m 2 ), and obese (≥27.5 kg/m 2 )were significantly associated with higher in-hospital mortality [odds ratio 2.20 (95% confidence interval 1.65-2.94), 1.25 (1.01-1.49), and 1.48 (1.05-2.09), respectively]. BMI showed U-shaped dose-response associations with mortality, major complications, and multiple complications. BMI also showed a reverse J-shaped association with failure to rescue (death after major complications).

CONCLUSIONS

Both high BMI and low BMI were associated with mortality, major complications and multiple complications after esophagectomy for esophageal cancer. Patients with low BMI were more likely to die once a major complication occurred. The present results can assist with risk stratification in patients undergoing oncologic esophagectomy.

Nutrition management by a multidisciplinary team for prevention of nutritional deficits and morbidity following esophagectomy

This study evaluated the effects of perioperative nutrition management by a multidisciplinary team on nutrition and postoperative complications of patients with esophageal cancer. A total of 239 patients with esophageal cancer who underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between February 2019 and February 2020 were included in the study. They were divided into the experimental group (120 patients) and the control group (119 patients) using the random number table method. Control group patients received routine diet management and experimental group patients received perioperative nutrition management by a multidisciplinary team. The differences of nutriture and postoperative complications between the two groups were compared. At 3 and 7 days after surgery, the experimental group patients had higher total protein and albumin levels (P<0.05), shorter postoperative anal exhaust time (P<0.05), lower incidence of postoperative gastrointestinal adverse reactions, pneumonia, anastomotic fistula, hypoproteinemia (P<0.05), and lower hospitalization costs (P<0.05) than the control group. Nutrition management by a multidisciplinary team effectively improved the nutriture of patients, promoted the rapid recovery of postoperative gastrointestinal function, reduced postoperative complications, and reduced hospitalization costs.

Efficacy and safety of self-expanding metal stents in patients with inoperable esophageal cancer: a real-life study

Background

Dysphagia is the most frequent symptom in patients diagnosed with esophageal cancer. Self-expanding metal stents (SEMS) are the current palliative treatment of choice for dysphagia in patients with non-curable esophageal cancer. This study aimed to evaluate the efficacy and adverse events (AEs) of different types of SEMS for palliation of dysphagia.

Methods

We performed a retrospective cohort study of patients with advanced esophageal cancer and SEMS placement for dysphagia palliation in a tertiary care center. The primary outcome was the clinical success defined as an improvement in dysphagia (reduction of at least 2 points in the Mellow-Pinkas scoring system for dysphagia) after SEMS placement.

Results

Between January 1999 and May 2020, 295 patients with esophageal cancer were identified. Among them, 75 had a SEMS placement for dysphagia palliation. The mean age of the patients was 61.3 years (standard deviation: 13.4), 69 patients (92%) were men, and the mean Mellow-Pinkas scoring for dysphagia pre- and post-SEMS placement were 3.1 and 1.4 (change from baseline -1.7), respectively. Technical success and clinical success were achieved in 98.6% and 58.9%, respectively. AEs were identified in 35/75 patients (46.7%), and SEMS migration was the most frequent AE in 22/75 patients (29.3%). There were no significant differences in improvement in dysphagia (p = 0.054), weight changes (p = 0.78), and AE (p = 0.73) among fully covered SEMS (fc-SEMS) and partially covered SEMS (pc-SEMS). The median follow-up was 89 days (interquartile range: 29-221).

Conclusion

SEMS placement was associated with a rapid improvement in dysphagia, high technical success, and a modest improvement in dysphagia with no major AE among fc-SEMS and pc-SEMS.

Adequate Management of Postoperative Complications after Esophagectomy: A Cornerstone for a Positive Outcome

BACKGROUND

Esophagectomy for cancer is one of the most complex procedures in visceral surgery. Postoperative complications negatively affect the patient's overall survival. They are not influenced by the histology type (adenocarcinoma (AC)/squamous cell carcinoma (SCC)), or the surgical approach (open, laparoscopic, or robotic-assisted). Among those dreadful complications are anastomotic leak (AL), esophago-respiratory fistula (ERF), and chylothorax (CT).

METHODS

In this review, we summarize the methods to avoid these complications, the diagnostic approach, and new therapeutic strategies.

RESULTS

In the last 20 years, both centralization of the medical care, and the development of endoscopy and radiology have positively influenced the management of postoperative complications. For the purpose of their prevention, perioperative measures have been applied. The treatment includes conservative, endoscopic, and surgical approaches.

CONCLUSIONS

Post-esophagectomy complications are common. Prevention measures should be known. Early recognition and adequate treatment of these complications save lives and lead to better outcomes.

Is there a relationship between two different anesthetic methods and postoperative length of stay during radical resection of malignant esophageal tumors in China?: a retrospective cohort study

BACKGROUND

Data providing a relationship between the anesthetic method and postoperative length of stay (PLOS) is limited. We aimed to investigate whether general anesthesia alone or combined with epidural anesthesia might affect perioperative risk factors and PLOS for patients undergoing radical resection of malignant esophageal tumors.

METHODS

The study retrospectively analyzed the clinical data of 680 patients who underwent a radical esophageal malignant tumor resection in a Chinese hospital from January 01, 2010, to December 31, 2020. The primary outcome measure was PLOS, and the secondary outcome was perioperative risk-related parameters that affect PLOS. The independent variable was the type of anesthesia: general anesthesia (GA) or combined epidural-general anesthesia (E-GA). The dependent variable was PLOS. We conducted univariate and multivariate logistic regression and propensity score matching to compare the relationships of GA and E-GA with PLOS and identify the perioperative risk factors for PLOS. In this cohort study, the confounders included sociodemographic data, preoperative chemotherapy, coexisting diseases, laboratory parameters, intraoperative variables, and postoperative complications.

RESULTS

In all patients, the average PLOS was 19.85 ± 12.60 days. There was no significant difference in PLOS between the GA group and the E-GA group either before or after propensity score matching (20.01 days ± 14.90 days vs. 19.79 days ± 11.57 days, P = 0.094, 18.09 ± 9.71 days vs. 19.39 ± 10.75 days, P = 0.145). The significant risk factors for increased PLOS were lung infection (β = 3.35, 95% confidence interval (CI): 1.54-5.52), anastomotic leakage (β = 25.73, 95% CI: 22.11-29.34), and surgical site infection (β = 9.39, 95% CI: 4.10-14.68) by multivariate regression analysis. Subgroup analysis revealed a stronger association between PLOS and vasoactive drug use, blood transfusions, and open esophagectomy. The results remained essentially the same (stable and reliable) after subgroup analysis.

CONCLUSIONS

Although there is no significant association between the type of anesthesia(GA or E-GA) and PLOS for patients undergoing radical esophageal malignant tumor resection, an association between PLOS and lung infection, anastomotic leakage, and surgical site infection was determined by multivariate regression analysis. A larger sample future study design may verify our results.

Residing in a food desert is associated with an increased risk of readmission following esophagectomy for cancer

Background

Nutritional status is related to treatment outcomes for esophageal cancer. Residing in a food desert (FD) has been associated with worse outcomes in breast and colon cancer. We assessed the association of residing in a FD on 30-day outcomes of esophageal cancer patients who received tri-modality therapy.

Methods

A retrospective review of patients who underwent esophagectomy (1/2015 to 7/2020, in New Hampshire, USA) was performed. Patients were excluded if they did not undergo neo-adjuvant treatment, required treatment outside of standard Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) protocol, or lacked both pre and post neo-adjuvant treatment computed tomography (CT) scans for review. Demographics, nutrition parameters, treatment characteristics, 30-day complications and 90-day mortality were reviewed. FD status was defined by the United States Department of Agriculture (USDA) Food Access Research Atlas and cross-referenced with patients' home zip code. Readmission was defined as readmission to any hospital for any reason within 30-day of discharge. Univariable analysis was conducted using Student's t-test or Wilcoxon rank-sum for continuous variables, and Fisher's exact test for categorical variables. Multivariable logistic regression was then used to model readmission status on FD status adjusted for measures statistically associated with readmission status at the P<0.10 in univariable analyses.

Results

Seventy-eight patients were included in the analysis. Overall pre-treatment prevalence of sarcopenia was 11.5% (9/78) and did not vary by FD status. Univariable analysis, demonstrated few significant differences between those who were readmitted and those who were not. On unadjusted analysis, patients who lived in a FD were 5 times more likely to be readmitted [5.16; 95% confidence interval (CI): 1.70-15.67] compared to those who did not. Residing in a FD remained a significant risk factor for readmission after adjustment for operative time, discharge to a rehabilitation facility and development of a grade III/IV complication [adjusted odds ratio (OR): 6.38; 95% CI: 1.45-28.08].

Conclusions

Our data suggest that residing in a FD is a prognostic factor for readmission after tri-modality therapy for esophageal cancer. Clinicians need to be aware that previously established nutritional markers may not completely capture nutritional status and living in a FD may significantly increase the risk of readmission in these patients.

Efficacy of immunonutritional supplement after neoadjuvant chemotherapy in patients with esophageal cancer

Background

In recent years, preoperative nutrition has received great attention, especially for patients who received surgical reconstruction of the digestive tract such as esophagectomy. Preoperative nutrition therapy was reported to accelerate the patient's postoperative recovery. In addition, immune suppression, nausea, and vomiting may lead to poor immune and nutritional status of patients with esophageal cancer who underwent neoadjuvant chemotherapy (NAC), which is not conducive to surgery. Therefore, preoperative nutritional treatment is necessary for patients with esophageal cancer who underwent NAC.

Method

Patients with esophageal cancer who received NAC at Nanjing Jinling Hospital from January 2018 to September 2020 were retrospectively identified. Patients were divided into enteral immunonutrition (EIN) group (those who received a conventional diet and immunonutrition supplement, Peptisorb, Nutricia, 500 mL/day * 7 via oral intake), and control group (those who only received a conventional diet were divided into). The primary outcomes were immune and nutritional indicators changes, including immunoglobulin M (IgM), immunoglobulin A (IgA), immunoglobulin G (IgG), and albumin (ALB), which were measured at preoperative day (PRD) 7, PRD-1, postoperative day (POD) 1 and POD-7. The secondary outcomes were postoperative complications, adverse reactions, and length of hospital stay.

Results

A total of 124 eligible patients were included in the study, with 21 patients in EIN group. After 1:2 matching, significant difference in baseline characteristics between the two groups was not observed (EIN: n = 21, Control group: n = 42). Compared with the control group, the IgA is significantly increased in the EIN group at POD-7 (p = 0.017). However, we observed that the IgM level in the control group was significantly higher than those in the EIN group at POD-7 (p = 0.007). The incidence of pneumonia and total complications in the EIN group were significantly lower than those in control group (p = 0.024, p = 0.028, respectively). There is no significant difference in ALB and adverse reactions between two groups (p = 0.303, p = 0.108, respectively).

Conclusion

Immunonutritional supplement after NAC is an effective strategy to improve the postoperative immune status of esophageal cancer patients and could reduce the incidence of infectious complication. More well-designed prospective studies are needed to verify and update our finding.

Effects of preoperative nutrition on postoperative outcomes in esophageal cancer: a systematic review and meta-analysis

Postoperative enteral nutrition has been widely implemented in esophageal cancer, but the efficacy and safety of preoperative nutrition, particularly immune-enhancing nutrition (IEN), remain controversial. This meta-analysis aims to provide a quantitative synthesis of whether preoperative nutrition improves postoperative morbidity and mortality in patients with resectable esophageal cancer. A systematic search was conducted in Medline, Embase, Cochrane, and databases of clinical trials dated up to December 2019. Randomized controlled trials and observational studies comparing postoperative outcomes between esophageal cancer patients with and without preoperative nutritional support were included. Random-effects model was applied in the meta-analysis of primary outcomes (overall complication rate, in-hospital mortality) and secondary outcomes (infectious complication rate, anastomotic leak rate, length of postoperative hospital stay). Complications of feeding tube access and perioperative weight loss were evaluated by qualitative synthesis. Subgroup analyses were performed by stratifying immunonutrition and standard nutrition before surgery. Subgroup analysis of randomized controlled trials alone was also done. A total of 15 studies enrolling 1864 participants were included. The overall meta-analysis found that preoperative nutrition could reduce infectious complications (odds ratio [OR] = 0.51, 95% confidence interval [CI] [0.26, 0.98]; I2 = 48%) and length of hospital stay (mean difference = -2.10 day, 95% CI [-3.72, -0.47]; I2 = 78%) after esophagectomy, whereas no significant difference was revealed in the incidence of overall complications (OR = 0.76, 95% CI [0.52, 1.11]; I2 = 32%), in-hospital mortality (OR = 1.03, 95% CI [0.41, 2.61]; I2 = 12%), and anastomotic leak (OR = 1.05, 95% CI [0.69, 1.58]; I2 = 0%). Subgroup of preoperative immunonutrition showed more prominent benefits. The complication rate of feeding tube access was low (1.6-16%). In conclusion, preoperative nutrition is safe in esophageal cancer, but benefits are observed in infectious complication rate and length of stay on a limited scale. IEN holds more advantages over standard nutrition. Randomized trials in the context of nutritional support during neoadjuvant therapy are in demand.

Contemporary Management of Locally Advanced and Recurrent Rectal Cancer: Views from the PelvEx Collaborative

Pelvic exenteration is a complex operation performed for locally advanced and recurrent pelvic cancers. The goal of surgery is to achieve clear margins, therefore identifying adjacent or involved organs, bone, muscle, nerves and/or vascular structures that may need resection. While these extensive resections are potentially curative, they can be associated with substantial morbidity. Recently, there has been a move to centralize care to specialized units, as this facilitates better multidisciplinary care input. Advancements in pelvic oncology and surgical innovation have redefined the boundaries of pelvic exenterative surgery. Combined with improved neoadjuvant therapies, advances in diagnostics, and better reconstructive techniques have provided quicker recovery and better quality of life outcomes, with improved survival This article provides highlights of the current management of advanced pelvic cancers in terms of surgical strategy and potential future developments.

Percutaneous endoscopic gastrostomy prior to esophagectomy for esophageal cancer - a systematic review and meta-analysis

BACKGROUND

For resectable esophageal cancer (EC), it remains controversial whether to place percutaneous endoscopic gastrostomy (PEG) before the curative surgery to provide nutritional support during the neoadjuvant therapy.

OBJECTIVE

To compare surgical outcomes for patients who received preoperative PEG and those without PEG placement (No-PEG) insertion prior to surgery in a potentially operable EC.

METHODS

A comprehensive literature search was conducted to identify randomized and non-randomized studies comparing PEG and No-PEG groups.

RESULTS

Four retrospective studies with a total number of 1,027 patients were identified and included in this meta-analysis. The differences in anastomotic leakage, anastomotic stricture, morbidity, pulmonary complications, wound infection, and hospital stay were not statistically significant between the two groups. Operation time was significantly shorter in the PEG group. There was no PEG-related gastric conduit failure and no leak from the PEG site in the PEG group.

CONCLUSION

We conclude preoperative PEG for resectable EC is a safe procedure with no adverse effect on the gastric tube construction and anastomosis, it can be selectively inserted for EC patients with marked weight loss and malnutrition or those at risk of developing malnutrition during neoadjuvant therapy.

High-quality nursing can reduce the incidence of adverse events in esophageal cancer patients after operation in the intensive care unit and improve postoperative rehabilitation

OBJECTIVE

This research aimed at observing the effect of applying high-quality nursing in the intensive care unit (ICU) to esophageal cancer (EC) patients after radical resection.

METHODS

From January 2015 to February 2020, 155 EC patients who underwent radical resection were divided into the control group (CG; n=77) and the observation group (OG; n=78). The CG was given conventional nursing intervention, and the OG was given high-quality nursing intervention. The scores of the visual analogue scale (VAS), clinical related indexes, complications, self-rating anxiety scale (SAS), self-rating depression scale (SDS), nursing satisfaction and SF-36 of patients were compared.

RESULTS

After nursing, compared with the CG, the duration of the indwelling drainage tube, time to getting out of bed, recovery of bowel sounds and hospitalization in the OG was shorter, and the incidence of postoperative complications was less. In addition, after nursing, the VAS, SAS and SDS scores of patients in both groups decreased, and these indexes in the OG decreased more than those in the CG. Patients were investigated upon discharge, and it was revealed that the nursing satisfaction of patients in the OG was obviously better than that in the CG. Three months after the operation, the scores of general health (GH), mental health (MH), role-physical (RP), role emotional (RE) and vitality (VT) of patients in the OG were higher than those in the CG.

CONCLUSION

High-quality nursing exerts a better effect in the ICU for patients who underwent EC surgery; it can reduce pain and adverse events and promote rehabilitation.

Laparoscopic vs. open feeding jejunostomy insertion in oesophagogastric cancer

Background

Jejunal feeding is an invaluable method by which to improve the nutritional status of patients undergoing neoadjuvant and surgical treatment of oesophageal malignancies. However, the insertion of a feeding jejunostomy can cause significant postoperative morbidity. The aim of this study is to compare the outcomes of patients undergoing placement of feeding jejunostomy by conventional laparotomy with an alternative laparoscopic approach.

Methods

A retrospective review of data prospectively collected at the Oxford Oesophagogastric Centre between August 2017 and July 2019 was performed including consecutive patients undergoing feeding jejunostomy insertion.

Results

In the study period, 157 patients underwent jejunostomy insertion in the context of oesophageal cancer therapy, 126 (80%) by open technique and 31 (20%) laparoscopic. Pre-operative demographic and nutritional characteristics were broadly similar between groups. In the early postoperative period jejunostomy-associated complications were noted in 54 cases (34.4%) and were significantly more common among those undergoing open as compared with laparoscopic insertion (38.1% vs. 19.3%, P = 0.049). Furthermore, major complications were more common among those undergoing open insertion, whether as a stand-alone or at the time of staging laparoscopy (n = 11/71), as compared with insertion at the time of oesophagectomy (n = 3/86, P = 0.011).

Conclusions

This report represents the largest to our knowledge single-centre comparison of open vs. laparoscopic jejunostomy insertion in patients undergoing oesophagectomy in the treatment of gastroesophageal malignancy. We conclude that the laparoscopic jejunostomy insertion technique described represents a safe and effective approach to enteral access which may offer superior outcomes to conventional open procedures.

Preoperative nutritional counselling in patients undergoing oesophagectomy

BACKGROUND

Patients undergoing surgery for oesophageal cancer are at high risk of malnutrition due to pathology and neoadjuvent therapy. This study sought to determine if oesophageal cancer patients undergoing oesophagectomy achieve superior clinical outcomes when preoperative nutritional counselling is performed.

METHODS

Oesophageal cancer patients undergoing oesophagectomy were retrospectively divided into cohorts based on those who received (n = 48) and did not receive (n = 58) preoperative nutritional counselling. We compared weight loss, length of stay, 30-day readmission related to nutrition or feeding tube problems, and 90-day mortality.

RESULTS

Per cent weight loss was less in patients who received preoperative nutritional counselling. There was a trend toward decreased mean length of stay and there were fewer readmissions for feeding tube-related complications in patients who received counselling.

CONCLUSIONS

Nutritional counselling before surgery may lead to decreased weight loss and reduced readmissions for feeding tube-related complications in patients with oesophageal cancer undergoing oesophagectomy.

Preoperative nutritional status is associated with the prognosis for lung cancer

BACKGROUND

We investigated whether preoperative nutritional indicators predicted the prognosis for patients with early-stage non-small cell lung cancer.

METHODS

Data for stage I or stage IIA non-small cell lung cancer without lymph node metastasis patients who received anatomical lung resection and were followed-up at least five years after surgery (n = 286) were analyzed. We calculated geriatric nutritional risk index, prognostic nutritional index, controlling nutritional status score, and modified Glasgow prognostic score. Multivariate Cox proportional hazard model adjusting for age, BMI, complication, pathological stage, histology of squamous cell carcinoma, T factor, diffusing capacity for carbon monoxide, surgery and smoking status was fitted to evaluate the association between these nutritional indicators and mortality and recurrence within five years.

RESULTS

After adjusted for covariates other than type of surgery and diffusing capacity for carbon monoxide, controlling nutritional status of ≥3 was significantly associated with mortality (hazard ratio (HR) = 2.68, 95% confidence interval (CI) = 1.02, 7.01). The association remained marginally significant by adjusting for type of surgery and diffusing capacity for carbon monoxide (HR = 2.44, 95% CI = 0.92, 6.45). controlling nutritional status of ≥3 was significantly associated with recurrence (HR = 2.60; 95% CI: 1.20, 5.61) after adjusting for all covariates. Other nutritional indices did not predict the prognosis in multivariate analysis.

CONCLUSION

Preoperative high controlling nutritional status score was marginally and significantly associated with mortality and recurrence of non-small cell lung cancer patients after lung resection.

A Novel Technique for Radiographic Diagnosis of Sarcopenia that Accurately Predicts Postoperative Complications in Lower Extremity Free Flap Patients

INTRODUCTION

 Sarcopenia is linked to poor outcomes throughout the surgical literature and can be assessed on preoperative imaging to potentially aid in risk stratification. This study examined the effects of sarcopenia on surgical morbidity following lower extremity (LE) reconstruction, and also compared two methods of assessment, one of which is novel ("ellipse method").

METHODS

 A retrospective cohort study of 50 patients receiving free flap-based reconstruction of the LE was performed. Bilateral psoas density and area were quantified at L4 through tracing ("traditional method") and encircling ("ellipse method") to calculate Hounsfield unit average calculation (HUAC). Logistic regression and receiving operator curve analysis for the primary outcome of any postoperative complication was used to determine HUAC cutoffs (≤ 20.7 vs. ≤ 20.6) for sarcopenia. Risk of complications associated with sarcopenia was evaluated using Fisher's exact tests.

RESULTS

 Twelve patients (24%) met criteria for sarcopenia via the traditional method and 16 (32%) via the ellipse method. By both methods, sarcopenic patients were older and more often female and diabetic. These patients also had higher American Society of Anesthesiologists scores and lower serum prealbumin levels. The ellipse method was found to be more accurate, sensitive, and specific than the traditional method in predicting postoperative morbidity (p = 0.009). Via the ellipse method, sarcopenic patients were at higher risk for any complication (p = 0.002) and were at a higher risk for a deep vein thrombus or pulmonary embolism via the traditional method (p = 0.047).

CONCLUSION

 Sarcopenia is associated with greater pre- and postoperative morbidity in LE reconstruction. The novel ellipse method is a simplified and accurate method of assessing sarcopenia that can be easily performed in the clinical setting.

The Influence of Pretherapeutic and Preoperative Sarcopenia on Short-Term Outcome after Esophagectomy

Simple Summary

Although introducing minimally invasive surgery reduced postoperative morbidity after esophagectomy esophageal cancer still is a malignancy with poor prognosis. This study aimed to investigate whether preoperative sarcopenia has an influence on short-term postoperative outcome after esophagectomy in esophageal cancer patients. Our findings suggest that preoperative sarcopenia is no independent prognostic factor for postoperative outcome after esophagectomy but that patients’ nutritional status consists of more factors than only body mass index (BMI) and muscle mass. Prehabilitation and preoperative optimization of the patients’ nutritional status seems to be an important factor for short-term postoperative outcome after esophagectomy.

Abstract

By introducing minimally invasive surgery the rate of postoperative morbidity in esophageal cancer patients could be reduced. But esophagectomy is still associated with a relevant risk of postoperative morbidity and mortality. Patients often present with nutritional deficiency and sarcopenia even at time of diagnosis. This study focuses on the influence of skeletal muscle index (SMI) on postoperative morbidity and mortality. Fifty-two patients were included in this study. SMI was measured using computer tomographic images at the time of diagnosis and before surgery. Then, SMI and different clinicopathological and demographic features were correlated with postoperative morbidity. There was no correlation between SMI before neoadjuvant therapy (p = 0.5365) nor before surgery (p = 0.3530) with the short-term postoperative outcome. Regarding cholesterol level before surgery there was a trend for a higher risk of complications with lower cholesterol levels (p = 0.0846). Our findings suggest that a low preoperative SMI does not necessarily predict a poor postoperative outcome in esophageal cancer patients after esophagectomy but that there are many factors that influence the nutritional status of cancer patients. To improve nutritional status, cancer patients at our clinic receive specialized nutritional counselling during neoadjuvant treatment as well as after surgery.

A Prospective Randomized Trial Comparing Jejunostomy and Nasogastric Feeding in Minimally Invasive McKeown Esophagectomy

BACKGROUND

Early postoperative enteral nutrition is recommended for patients undergoing esophagectomy; however, the optimum method of tube feeding remains controversial. Thus, the aim of this study is to assess two common enteral nutrition methods after minimally invasive McKeown esophagectomy.

METHODS

A randomized controlled trial was performed with 120 patients who underwent minimally invasive McKeown esophagectomy from January 2017 to December 2018. The patients were randomly divided so that 58 patients were in the jejunostomy feeding (JF) group and 62 patients were in the nasogastric feeding (NF) group. The postoperative outcomes, including complications, nutritional status, quality of life, and survival rate, were studied and used as the main parameters to compare the abovementioned tube feeding methods.

RESULTS

The incidence of overall complications was equivalent between the two groups (P = 0.625), except for bowel obstruction (which occurred 4 times in the JF group but did not occur in the NF group). In the first month after surgery (postoperative month 1, POM1), a significantly higher body mass index (BMI) was observed in the JF group (23.6 ± 3.2) than in the NF group (20.9 ± 3.5, P = 0.032). The global quality-of-life scores were better in the JF group than in the NF group (P < 0.001). In addition, there were no significant differences between the two groups in terms of disease-free survival (DFS) (P = 0.816) and overall survival (OS) (P = 0.564).

CONCLUSIONS

Compared with NF, JF provides more safety, efficacy, and utility as nutritional support for minimally invasive McKeown esophagectomy patients who have a high incidence of anastomotic leakage. However, the higher risk of intestinal obstruction after JF requires attention.

The impact of properly diagnosed sarcopenia on postoperative outcomes after gastrointestinal surgery: A systematic review and meta-analysis

Background

Sarcopenia is defined as the loss of muscle mass combined with loss of muscle strength, with or without loss of muscle performance. The use of this parameter as a risk factor for complications after surgery is not currently used. This meta-analysis aims to assess the impact of sarcopenia defined by radiologically and clinically criteria and its relationship with complications after gastrointestinal surgeries.

Materials and methods

A review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO registration number: CRD42019132221). Articles were selected from the PUBMED and EMBASE databases that adequately assessed sarcopenia and its impact on postoperative complications in gastrointestinal surgery patients. Pooled estimates of pre-operative outcome data were calculated using the odds ratio (OR) and 95% confidence interval (CI). Subgroup analysis were performed to assess each type of surgery.

Results

The search strategy returned 1323, with 11 studies meeting the inclusion criteria. A total of 4265 patients were analysed. The prevalence of sarcopenia between studies ranged from 6.8% to 35.9%. The meta-analysis showed an OR for complications after surgery of 3.01 (95% CI 2.55–3.55) and an OR of 2.2 (95% CI 1.44–3.36) for hospital readmission (30 days).

Conclusion

Sarcopenia, when properly diagnosed, is associated with an increase in late postoperative complications, as well as an increase in the number of postoperative hospital readmissions for various types of gastrointestinal surgery. We believe that any preoperative evaluation should include, in a patient at risk, tests for the diagnosis of sarcopenia and appropriate procedures to reduce its impact on the patient’s health.

Novel technique to repair a bronchopleural fistula after esophagectomy using wide intercostal muscle flap fixed by azygos vein and bronchus: a case report

Background

Post-esophagectomy bronchopleural fistulas can be life-threatening in patients who are exhausted, for example, by surgical stress and pleural infection; therefore, establishment of a reliable surgical procedure is extremely important. We here report a novel procedure entailing muscle flap closure for bronchopleural fistula.

Case presentation

A 64-year-old man developed a right bronchopleural fistula after esophagectomy. Because he was exhausted by surgical stress and malnourished, we considered reliable surgical closure of the fistula essential. Intraoperatively, it was found to connect with the membranous portion of the right main bronchus. We decided to close the fistula with a pedicled fourth and fifth intercostal muscle flap. After separating the intercostal muscles near the angle of the rib, we passed a muscle flap between the azygos vein and bronchus and sutured it securely to the fistula. The postoperative course was uneventful, and there was no thoracic infection. Postoperative bronchoscopy confirmed the muscle flap had securely closed the fistula.

Conclusions

The route and suturing technique of the intercostal muscle flap to a fistula are important, especially in exhausted patients.
