Dietician-delivered intensive nutritional support is associated with a decrease in severe postoperative complications after surgery in patients with esophageal cancer

Effect of Preoperative Nutritional Risk Screening and Enteral Nutrition Support in Accelerated Recovery after Resection for Esophageal Cancer

Patients with esophageal cancer are often accompanied by malnutrition, especially in patients with obvious swallowing tract. Many studies have shown that preoperative nutritional support can reduce postoperative complications, but there are few studies comparing preoperative enteral nutrition with intravenous nutrition. The aim of the study was to compare the effects of the two nutritional support path in esophageal cancer patients undergoing surgery. We used the nutritional risk screening 2002 (NRS2002) for preoperative nutritional risk screening in patients with esophageal cancer treated at our department between April 2016 and March 2019. A total of 56 patients with an NRS2002 score ≥ 3 and with apparent difficulty swallowing received preoperative parenteral nutrition (PN; n = 29) or enteral nutrition (EN; n = 27). Both groups received 7 day of nutritional support before surgery. Nutritional indicators were measured on preoperative day 7, preoperative day 1, and postoperative day 7. The baseline characteristics, perioperative condition, nutritional status, and postoperative complications of the two groups were compared and analysed. There was no significant difference in baseline characteristics and perioperative nutrition indicators between two groups. Postoperative hospital stay and the costs of nutrition support were significantly reduced in the EN group compared with PN group (P = 0.000). The times of first passing gas and bowel movement were shorter in the EN group compared with PN group (P = 0.001). The incidence of gastrointestinal complications was lower in the EN group compared with PN group (P = 0.039). For esophageal cancer patients with an NRS2002 score ≥ 3 and apparent difficulty swallowing, preoperative EN with a gastric tube is safe and easy to perform. Preoperative EN can shorten the recovery time of gastrointestinal function, reduce the incidence of gastrointestinal complications, finally accelerate postoperative recovery.

The enhanced recovery after surgery (ERAS) protocol to promote recovery following esophageal cancer resection

Esophageal cancer surgery, comprising esophagectomy with radical lymphadenectomy, is a complex procedure associated with considerable morbidity and mortality. The enhanced recovery after surgery (ERAS) protocol which aims to improve perioperative care, minimize complications, and accelerate recovery is showing promise for achieving better perioperative outcomes. ERAS is a multimodal approach that has been reported to shorten the length of hospital stay, reduce surgical stress response, decrease morbidity, and expedite recovery. While ERAS components straddle preoperative, intraoperative, and postoperative periods, they need to be seen in continuum and not as isolated elements. In this review, we elaborate on the components of an ERAS protocol after esophagectomy including preoperative nutrition, prehabilitation, counselling, smoking and alcohol cessation, cardiopulmonary evaluation, surgical technique, anaesthetic management, intra- and postoperative fluid management and pain relief, mobilization and physiotherapy, enteral and oral feeding, removal of drains, and several other components. We also share our own institutional protocol for ERAS following esophageal resections.

Multidisciplinary team management for prevention of pneumonia and long-term weight loss after esophagectomy: a single-center retrospective study

BACKGROUND

In April 2017, we launched the multidisciplinary Hamamatsu Perioperative Care Team (HOPE) for all surgical patients. We developed a reinforced intervention strategy, particularly for esophagectomy. We herein report the outcomes of the HOPE at 2 years after commencement.

METHODS

A total 125 patients underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between January 2014 and December 2018 at the Department of Surgery in Hamamatsu University School of Medicine. The patients were divided into the pre-HOPE group including 62 patients who underwent esophagectomy before the introduction of the HOPE and the HOPE group including 63 patients who underwent esophagectomy after the introduction of the HOPE. The outcomes of surgery were compared between the two groups.

RESULTS

There were no significant differences in the clinicopathological characteristics between the two groups. The incidence rates of atrial fibrillation and pneumonia were significantly lower in the HOPE group than in the pre-HOPE group (6% vs. 19%, p = 0.027 and 14% vs. 29%, p = 0.037, respectively). The estimated calorie doses at the time of discharge were approximately 750 and 1500 kcal/day in the pre-HOPE group and the HOPE group, respectively. The body weight loss was significantly less in the HOPE group than the pre-HOPE group at 1, 3, 6, and 12 months postoperatively than that before the surgery (p < 0.001).

CONCLUSIONS

The introduction of the multidisciplinary HOPE was associated with a significant reduction in the incidence of postoperative pneumonia and significantly less weight loss.

Preoperative nutritional optimization of esophageal cancer patients

Optimization of the nutritional and metabolic state prior to major surgery leads to improved surgical outcomes and is increasingly seen as an important part of oncology disease management. For locally advanced esophageal cancer the treatment is multimodal, including neoadjuvant chemoradiotherapy or perioperative chemotherapy in combination with esophageal resection. Patients undergoing such a multimodal treatment have a higher risk for progressive decline in their nutritional status. Preoperative malnutrition and loss of skeletal muscle mass has been reported to correlate with unfavorable outcomes in patients who undergo esophageal cancer surgery. Decline in nutritional status is most likely caused by insufficient nutritional intake, reduced physical activity, systemic inflammation and the effects of anticancer therapy. To ensure an optimal nutritional status prior to surgery, it is key to assess the nutritional status in all preoperative esophageal cancer patients, preferable early in the treatment trajectory, and to apply nutritional interventions accordingly. Nutritional management of esophageal cancer can be challenging, the optimal nutritional therapy is still under debate, and warrants more nutritional scientific research. In this review, the most recent findings regarding preoperative nutrition associated with outcomes in patients with esophageal cancer will be explored.

Long-term weight development after esophagectomy for cancer-comparison between open Ivor-Lewis and minimally invasive surgical approaches

Esophagectomy is an extensive procedure with severe postoperative effects. It can be assumed that the greater the trauma, the longer the nutritional recovery. This retrospective observational single-center cohort study compared weight development after esophagectomy with open and minimally invasive techniques. Three groups were compared in this study, one representing the first 41 patients who underwent the minimally invasive McKeown esophagectomy (MIMK). The second group included the first 84 consecutive patients operated with the minimally invasive Ivor-Lewis esophagectomy (MIIL). The third group comprised 100 consecutive patients operated with open thoracoabdominal Ivor-Lewis esophagectomy (IL). Virtually all patients submitted to a minimally invasive esophagectomy (MIE) and the majority with an IL had a jejunal catheter inserted during operation for postoperative enteral feeding. All together 225 patients were included in this study. The mean weight loss during the first year was 13.1% (±4.1), 11.2% (±6.1), and 9.6% (±7.5) in the IL, MIIL, and MIMK group, respectively (P = 0.85 and P = 0.95, respectively). The median duration of postoperative enteral nutrition support varied substantially within the groups and was 23.5 days in the IL group (range: 0-2033 days), 54.5 days in those having an MIIL (range: 0-308 days; P ≤ 0.001) and 57.0 days among patients in the MIMK group (range: 0-538 days; P ≤ 0.022). There was no difference in the risk of losing at least 10% of the preoperative weight at 3 or 6 months postoperatively between the groups. However, in patients who suffered severe complications (Clavien-Dindo score ≥ IIIb) after MIIL, there was a nonsignificant trend toward a lower risk of a 10% or greater weight loss, 3 months postoperatively. In conclusion, the greater surgical trauma associated with the traditional open esophagectomy was not followed by more severe weight loss, or other signs of poorer nutritional recovery, when compared to minimal invasive surgical techniques.

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.

Nutrition therapy in esophageal cancer-Consensus statement of the Gastroenterological Society of Taiwan

A number of clinical guidelines on nutrition therapy in cancer patients have been published by national and international societies; however, most of the reviewed data focused on gastrointestinal cancer or non-cancerous abdominal surgery. To collate the corresponding data for esophageal cancer (EC), a consensus panel was convened to aid specialists from different disciplines, who are involved in the clinical nutrition care of EC patients. The literature was searched using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the ISI Web of Knowledge. We searched for the best evidence pertaining to nutrition therapy in the case of EC. The panel summarized the findings in 3 sections of this consensus statement, based on which, after the diagnosis of EC, an initial distinction is made between the patients, as follows: (1) Assessment; (2) Therapy in patients with resectable disease; patients receiving chemotherapy or chemoradiotherapy prior to resection, and patients with unresectable disease, requiring chemoradiotherapy or palliative therapy; and (3) Formula. The resulting consensus statement reflects the opinions of a multidisciplinary group of experts, and a review of the current literature, and outlines the essential aspects of nutrition therapy in the case of EC. The statements are: Patients with EC are among one of the highest risk to have malnutrition. Patient generated suggestive global assessment is correlated with performance status and prognosis. Nutrition assessment for patients with EC at the diagnosis, prior to definitive therapy and change of treatment strategy are suggested and the timing interval can be two weeks during the treatment period, and one month while the patient is stable. Patients identified as high risk of malnutrition should be considered for preoperative nutritional support (tube feeding) for at least 7-10 days. Various routes for tube feedings are available after esophagectomy with similar nutrition support benefits. Limited intrathoracic anastomotic leakage postesophagectomy can be managed with intravenous antibiotics and self-expanding metal stent (SEMS) or jejunal tube. Enteral nutrition in patients receiving preoperative chemotherapy or chemoradiation provides benefits of maintaining weight, decreasing toxicity, and preventing treatment interruption. Tube feeding or SEMS can offer nutrition support in patients with unresectable esophageal cancer, but SEMS is not recommended for those with neoadjuvant chemoradiation before surgery. Enteral immunonutrition may preserve lean body mass and attenuates stress response after esophagectomy. Administration of glutamine may decrease the severity of chemotherapy induced mucositis. Enteral immunonutrition achieves greater nutrition status or maintains immune functions during concurrent chemoradiation.

Recent progress in perioperative management of patients undergoing esophagectomy for esophageal cancer

Esophagectomy remains the mainstay of curative intent treatment for esophageal cancer. Oncologic esophagectomy is a highly invasive surgery and both morbidity and mortality rates still remain high. Recently, it has been revealed that multidisciplinary perioperative management can decrease the postoperative complications after esophagectomy. In this review, we summarized the recent progress in each component of multidisciplinary perioperative care bundle, including oral hygiene, cessation of smoking and alcohol, respiratory training, measurement of physical fitness, swallowing evaluation and rehabilitation, nutritional support, pain control and management of delirium. The accumulation of evidence and the popularization of knowledge will increase safety of esophagectomy and thus improve the outcome of patients with esophageal cancer.

Different strategy of salvage esophagectomy between residual and recurrent esophageal cancer after definitive chemoradiotherapy

BACKGROUND

Clinical outcomes appear to differ between patients with residual or recurrent esophageal cancer after definitive chemoradiotherapy. We aimed to identify the patients most likely to benefit from this high-risk surgery, divided by the patients whose cancer was residual and recurrent groups, respectively.

METHODS

We retrospectively examined 100 cases of patients who failed to respond to definitive chemoradiotherapy for thoracic esophageal squamous cell carcinoma and subsequently underwent salvage transthoracic esophagectomy.

RESULTS

In-hospital morbidity was similar in both groups. T status prior to administration of chemoradiotherapy correlated with survival in the group with residual cancer (P=0.010), but this relationship was not significant in the group with recurrent cancer (P=0.635). On the other hand, pathological T status showed a significant correlation with survival in both the residual (P<0.001) and recurrent groups (P=0.001). Patients with T3 disease in the recurrent group showed better survival, similar to T0-2 patients, while worse survival was demonstrated in the residual group. In the recurrent group, N status before chemoradiotherapy did not correlate with survival (P=0.895).

CONCLUSIONS

Patients with residual cancer would have good prognosis by salvage esophagectomy in cases in which the cancer had not invaded to the adventitia at the time of chemoradiotherapy and surgery. Conversely, patients whose cancer was recurrent might benefit from salvage surgery if the cancer appears to be resectable. T and N status before chemoradiotherapy are not important factors in consideration of salvage esophagectomy in cases of recurrent cancer.

Influence of nutritional status on postoperative outcome in patients with colorectal cancer - the emerging role of the microbiome

Many patients with colorectal cancer are overweight. Even then, nutritional status is a frequently underestimated risk factor for perioperative complications. Enhanced Recovery after Surgery is the goal for perioperative management, and preoperative nutritional risk screening should be a standard. In case of nutritional risk, perioperative nutrition therapy should be started without delay and should follow recent guideline recommendations. The preservation of the microbiome has an emerging role in preventing postoperative anastomotic leakage and septic complications. The time window for recovery after neoadjuvant treatment for rectal cancer may be used for conditioning appropriate-risk patients in a “prehabilitation” program. In order to assess metabolic recovery and the prognosis for long-term survival, C-reactive protein/albumin ratio may be a promising parameter, which has to be validated in the future. This narrative review summarizes recent strategies and guideline recommendations.

Nutritional aspects of enhanced recovery after esophagectomy with gastric conduit reconstruction

Enhanced Recovery After Surgery (ERAS) aims to accelerate recovery by a set of multimodality management strategies. For esophagectomy, several nutritional elements of ERAS can be safely introduced and are advised in routine practice, including preadmission counseling to screen and treat for potential malnutrition, shortened preoperative fasting, and carbohydrate loading. However, the timing of oral intake and the use of routine nasogastric decompression remain matter of debate after esophagectomy. Furthermore, more research is needed on future developments such as perioperative immunonutrition.

Handgrip Strength Is Associated With Treatment Modifications During Neoadjuvant Chemoradiation in Patients With Esophageal Cancer

RATIONALE

It has been shown that early nutrition intervention improves nutrition status (NS) and treatment tolerance in patients with esophageal cancer. However, it remains unknown whether pretreatment parameters of NS are associated with treatment modifications (TMs) during neoadjuvant chemoradiation (CR) in patients who are intensively nutritionally supervised during treatment.

METHODS

All outpatients with esophageal cancer who were scheduled for CR in the VU medical center from 2006-2015 were included. NS was assessed by body mass index (BMI), weight loss in the past 6 months (WL), fat mass index (FMI) and fat-free mass index (FFMI), handgrip strength (HGS), and energy/protein intake. Logistic regression analyses, adjusted for age, sex, previous tumor, tumor stage, and physical status, were applied. TMs were defined as delay, dose reduction or discontinuation of chemotherapy and/or radiotherapy, hospitalization, or mortality (yes/no).

RESULTS

In total, 162 patients were included (73% male; mean age 65 ± 9 years). Mean BMI was 25.1 ± 4.5 kg/m2, and WL was 4.8 ± 5.1 kg. HGS and FFMI were below the 10th percentile of reference values in 21 and 37 patients, respectively. Thirty-five (22%) patients experienced at least 1 TM during CR; unplanned hospitalization (n = 18, 11%) was the most prevalent. After adjustments for confounders, only HGS was statistically significantly associated with TMs (odds ratio, 0.93; 95% confidence interval, 0.88-1.00).

CONCLUSION

In this group of intensively supervised patients with esophageal cancer, pretreatment parameters of NS had little influence on TMs during CR. Only a lower HGS was associated with TMs.

Evaluating Factors for Prophylactic Feeding Tube Placement in Gastroesophageal Cancer Patients Undergoing Chemoradiotherapy

PURPOSE

Though better studied in head/neck cancers, there are currently no studies on timing of feeding tube (FT) placement in patients with gastroesophageal cancer. This study sought to discern characteristics of patients who used versus did not use a prophylactic FT (pFT), and also analyzed factors associated with placement of FTs during chemoradiotherapy (CRT).

METHODS/MATERIALS

From 1998 to 2013, 1,329 patients underwent neoadjuvant CRT, of which 323 received an FT. Patients for whom FTs were placed prior to treatment due to tumor occlusion or substantial weight loss (n = 130), and those with FTs placed following treatment (n = 43) were excluded. One hundred patients had pFTs placed, and 50 underwent placement during CRT. The following was collected for each patient: demographic/patient information, oncologic/treatment characteristics, and CRT tolerance.

RESULTS

No significant differences were found in any parameter between cohorts that used (n = 66) versus did not use a pFT (n = 34); on univariate and multivariate analyses, no pretreatment characteristic associated with using a pFT. When compared with patients who used a pFT (n = 66), those who required an FT during CRT (n = 50) had lower body mass index (p = 0.045), underwent higher-dose radiotherapy (p = 0.003), and received induction chemotherapy (p = 0.031). On multivariate analysis, receipt of induction chemotherapy and greater weight loss and esophagitis during treatment were associated with placement of FTs during CRT (p < 0.05).

CONCLUSION

Of our cohort who received pFTs, there were no clinical factors that predicted for their use. Patients must be closely monitored for weight loss and esophagitis when receiving CRT in order to intervene prior to further worsening of toxicities.

Nutrition in peri-operative esophageal cancer management

Nutritional status and dietary intake are increasingly recognized as essential areas in esophageal cancer management. Nutritional management of esophageal cancer is a continuously evolving field and comprises an interesting area for scientific research. Areas covered: This review encompasses the current literature on nutrition in the pre-operative, peri-operative, and post-operative phases of esophageal cancer. Both established interventions and potential novel targets for nutritional management are discussed. Expert commentary: To ensure an optimal pre-operative status and to reduce peri-operative complications, it is key to assess nutritional status in all pre-operative esophageal cancer patients and to apply nutritional interventions accordingly. Since esophagectomy results in a permanent anatomical change, a special focus on nutritional strategies is needed in the post-operative phase, including early initiation of enteral feeding, nutritional interventions for post-operative complications, and attention to long-term nutritional intake and status. Nutritional aspects of pre-optimization and peri-operative management should be incorporated in novel Enhanced Recovery After Surgery programs for esophageal cancer.

Nutritional status, management and clinical outcomes in patients with esophageal and gastro-oesophageal cancers: A descriptive study

AIM

The aims of this study were to investigate the nutritional management practice and nutritional status of patients with oesophageal and gastro-oesophageal cancers, and to propose strategies for improving their nutritional and clinical outcomes.

METHODS

All patients diagnosed with oesophageal and gastro-oesophageal cancers and treated with chemotherapy and/or radiotherapy at the Liverpool Cancer Therapy Centre (between August 2010 and February 2014) were included in this retrospective study. Patient and tumour characteristics, nutritional status and management were compared to clinical outcomes.

RESULTS

A total of 69 patients met the inclusion criteria. The median weight loss prior to treatment commencement was 10.5% (Interquartile Range (IQR) = 6.6-15.4). A decline in nutritional status continued throughout the treatment course. The median percentage of weight loss during treatment was 3.53% (IQR = 0.00-6.84). Seven and 19 patients required nutrition intervention using a feeding tube or stent insertion to manage dysphagia, respectively. In patients treated with a curative intent, radiotherapy was completed in 100% of those with a nasogastric tube insertion as compared to 80% who had a stent insertion. There was a higher percentage of patients from culturally and linguistically diverse (CALD) background, experiencing significant weight loss when compared with their non-CALD counterparts (P = 0.04).

CONCLUSIONS

Patients with oesophageal and gastro-oesophageal cancers commonly present with significant weight loss and this continues during the course of their anti-cancer treatment. A standardised protocol of nutrition management for these cancer patients is recommended, focusing on assisting patients from CALD backgrounds.

ESPEN guidelines on nutrition in cancer patients

Cancers are among the leading causes of morbidity and mortality worldwide, and the number of new cases is expected to rise significantly over the next decades. At the same time, all types of cancer treatment, such as surgery, radiation therapy, and pharmacological therapies are improving in sophistication, precision and in the power to target specific characteristics of individual cancers. Thus, while many cancers may still not be cured they may be converted to chronic diseases. All of these treatments, however, are impeded or precluded by the frequent development of malnutrition and metabolic derangements in cancer patients, induced by the tumor or by its treatment. These evidence-based guidelines were developed to translate current best evidence and expert opinion into recommendations for multi-disciplinary teams responsible for identification, prevention, and treatment of reversible elements of malnutrition in adult cancer patients. The guidelines were commissioned and financially supported by ESPEN and by the European Partnership for Action Against Cancer (EPAAC), an EU level initiative. Members of the guideline group were selected by ESPEN to include a range of professions and fields of expertise. We searched for meta-analyses, systematic reviews and comparative studies based on clinical questions according to the PICO format. The evidence was evaluated and merged to develop clinical recommendations using the GRADE method. Due to the deficits in the available evidence, relevant still open questions were listed and should be addressed by future studies. Malnutrition and a loss of muscle mass are frequent in cancer patients and have a negative effect on clinical outcome. They may be driven by inadequate food intake, decreased physical activity and catabolic metabolic derangements. To screen for, prevent, assess in detail, monitor and treat malnutrition standard operating procedures, responsibilities and a quality control process should be established at each institution involved in treating cancer patients. All cancer patients should be screened regularly for the risk or the presence of malnutrition. In all patients - with the exception of end of life care - energy and substrate requirements should be met by offering in a step-wise manner nutritional interventions from counseling to parenteral nutrition. However, benefits and risks of nutritional interventions have to be balanced with special consideration in patients with advanced disease. Nutritional care should always be accompanied by exercise training. To counter malnutrition in patients with advanced cancer there are few pharmacological agents and pharmaconutrients with only limited effects. Cancer survivors should engage in regular physical activity and adopt a prudent diet.

[Impact of perioperative nutritional therapy on risk and complication management in patients undergoing esophagectomy for cancer]

Esophagectomy is considered to be a high risk procedure regarding postoperative morbidity and mortality. Therefore, in Germany, these operations are limited to hospitals fulfilling a minimum quantity. This systematic review focuses on risk and complication management regarding the impact of perioperative nutritional therapy, including the recent S3-guideline recommendations and comments of the German Working Group of Medical Societies (AWMF) which were established with contributions from the authors.

Cachexia in patients with oesophageal cancer

Oesophageal cancer is a debilitating disease with a poor prognosis, and weight loss owing to malnutrition prevails in the majority of patients. Cachexia, a multifactorial syndrome characterized by the loss of fat and skeletal muscle mass and systemic inflammation arising from complex host-tumour interactions is a major contributor to malnutrition, which is a determinant of tolerance to treatment and survival. In patients with oesophageal cancer, cachexia is further compounded by eating difficulties owing to the stage and location of the tumour, and the effects of neoadjuvant therapy. Treatment with curative intent involves exceptionally extensive and invasive surgery, and the subsequent anatomical changes often lead to eating difficulties and severe postoperative malnutrition. Thus, screening for cachexia by means of percentage weight loss and BMI during the cancer trajectory and survivorship periods is imperative. Additionally, markers of inflammation (such as C-reactive protein), dysphagia and appetite loss should be assessed at diagnosis. Routine assessments of body composition are also necessary in patients with oesophageal cancer to enable assessment of skeletal muscle loss, which might be masked by sarcopenic obesity in these patients. A need exists for clinical trials examining the effectiveness of therapeutic and physical-activity-based interventions in mitigating muscle loss and counteracting cachexia in these patients.

A comparison of postoperative early enteral nutrition with delayed enteral nutrition in patients with esophageal cancer

We examined esophageal cancer patients who received enteral nutrition (EN) to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3) based on whether they received EN within 48 h, 48 h-72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH), days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019). Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

Strategies to reduce pulmonary complications after esophagectomy

Esophagectomy, the surgical removal of all or part of the esophagus, is a surgical procedure that is associated with high morbidity and mortality. Pulmonary complications are an especially important postoperative problem. Therefore, many perioperative strategies to prevent pulmonary complications after esophagectomy have been investigated and introduced in daily clinical practice. Here, we review these strategies, including improvement of patient performance and technical advances such as minimally invasive surgery that have been implemented in recent years. Furthermore, interventions such as methylprednisolone, neutrophil elastase inhibitor and epidural analgesia, which have been shown to reduce pulmonary complications, are discussed. Benefits of the commonly applied routine nasogastric decompression, delay of oral intake and prophylactic mechanical ventilation are unclear, and many of these strategies are also evaluated here. Finally, we will discuss recent insights and new developments aimed to improve pulmonary outcomes after esophagectomy.

Comparison of the prognostic values of various nutritional parameters in patients with esophageal squamous cell carcinoma from Southern China

BACKGROUND

Nutritional evaluation is important for patients with esophageal cancer, but the impact of undernutrition on outcome of those patients is not well elucidated. Our aim is to assess the impact of baseline nutritional status on overall survival (OS) in Chinese patients with esophageal squamous cell carcinoma (ESCC) and to detect a most appropriate indicator for nutritional evaluation.

METHODS

502 patients from Southern China diagnosed as ESCC in Sun Yat-Sen University Cancer Center were included. A series of nutritional indicators were introduced to evaluate the baseline nutritional status. Kaplan-Meier method was used to estimate the 5-year OS and the log-rank test was used to determine the survival differences. Cox proportional hazards model was used in the univariate and multivariate analyses of OS.

RESULTS

With a median follow up time of 30 months, the median OS for the entire patient group was 37.3 months with the 5-year OS rate of 43.0%. Only performance status, AJCC 6th stage and body mass index (BMI) were the independent prognostic factors in multivariate analysis of OS. The median OS for patients with BMI less than 18.5, patients with BMI within 18.5-24.9 and patients with BMI more than 24.9 were 19.2, 43.2 and 51.6 months, respectively, with the 5-year OS rates of 25.2%, 46.1% and 48.1% (P<0.001). Patients with BMI <18.5 tended to present with a more advanced stage disease and a poorer tumor grade.

CONCLUSIONS

Baseline nutritional status is predictive of OS in Chinese patients with ESCC. BMI is a steady indicator for nutritional evaluation and a sensitive prognostic parameter for ESCC patients. Treatment optimization in ESCC patients with low BMI should integrate the modalities and individual nutritional support.
