Abstract
Diaphragmatic hernia is a very rare but high-risk complication after esophagectomy. Although there are many studies on the Ivor Lewis esophagectomy procedure for diaphragmatic hernia, there are fewer studies on the McKeown procedure. The present study aimed to estimate the incidence of diaphragmatic hernia after esophagectomy, describing its presentation and management with the McKeown procedure. We retrospectively evaluated the 622 patients who underwent radical esophagectomy between January 2002 and December 2020 at the Wakayama Medical University Hospital. Statistical analyses were performed to evaluate risk factors for diaphragmatic hernia. Emergency surgery for postoperative diaphragmatic hernia was performed in nine of 622 patients (1.45%). Of these nine patients, one developed prolapse of the small intestine into the mediastinum (11.1%). The other eight patients underwent posterior mediastinal route reconstructions (88.9%), one of whom developed prolapse of the gastric conduit, and seven of whom developed transverse colon via the diaphragmatic hiatus. Laparoscopic surgery was identified in multivariate analysis as the only independent risk factor for diaphragmatic hernia (odd's ratio [OR] = 9.802, p = 0.034). In all seven cases of transverse colon prolapse into the thoracic cavity, the prolapsed organ had herniated from the left anterior part of gastric conduit. Laparoscopic surgery for esophageal cancer is a risk factor for diaphragmatic hernia. The left anterior surface of gastric conduit and diaphragmatic hiatus should be fixed firmly without compromising blood flow to the gastric conduit.

The impact of thoracic duct resection on the long-term body composition of patients who underwent esophagectomy for esophageal cancer and survived without recurrence. Dis Esophagus 2023; 36:doad002. [PMID: 37465862 PMCID: PMC10473448 DOI: 10.1093/dote/doad002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 12/27/2022] [Indexed: 07/20/2023]
Abstract
BACKGROUND We have reported the possible benefits of radical esophagectomy with thoracic duct (TD) resection in elective esophageal cancer surgery. However, the effect of TD resection on the long-term nutrition status remains unclear. METHODS Patients who underwent esophagectomy at Keio University between January 2006 and December 2018 were included, and those who had no recurrence for more than three years were evaluated. Changes in each body composition (muscle mass and body fat) were comparatively assessed between those who underwent TD resection or not, before and at, one, three and five years after surgery. Computed tomography images were analyzed on postoperative year 1, 3 and 5. RESULTS This study included 217 patients categorized in the TD-resected (TD-R) (156 patients) and TD-preserved (TD-P) (61 patients) groups. The loss of muscle mass was comparable between the groups. On the other hand, the loss of adipose tissues was significantly greater in the TD-R group than in the TD-P group at one and three years after surgery, while there was no statistical difference five years after surgery. Additionally, among patients with cT1N0M0 disease in whom survival advantage of TD resection has been reported previously, the loss of muscle mass did not differ between each group. CONCLUSIONS The change of muscle mass between the two groups was comparable. Although body fat mass was reduced by TD resection, it eventually recovered in the long term. In patients with esophageal cancer, TD resection may be acceptable without significant impact on body composition in the long term.

Abstract
Esophageal surgery has evolved significantly since the first esophagectomy, with advancements in diagnosis allowing medicine to keep pace with the disease's increasing incidence. Multimodal treatment improves outcomes, but surgical resection remains imperative for local control, with various techniques in existence but none demonstrating clear superiority. More recently, minimally invasive and robotic surgery have further reduced perioperative morbidity. This review discusses techniques for esophageal resection, with attention to the options available for anastomosis and reconstructive conduits.

Abstract
BACKGROUND Minimally invasive esophagectomy (MIE) for esophageal cancer patients with sarcopenia is associated with a high risk of perioperative complications; however, the relationship between sarcopenia and the survival of esophageal cancer patients remains controversial. In this study, we aimed to develop a stratifying marker for sarcopenia to precisely predict patients' prognosis. METHODS We retrospectively studied 135 patients who underwent thoracoscopic esophagectomy at Kobe University Hospital from 2011 to 2015 and who were preoperatively diagnosed with or without sarcopenia based on the Asian Working Group for Sarcopenia index. Creatinine levels and albumin as measures of skeletal muscle volume and nutritional status, respectively, were used to develop a marker to be used for stratifying sarcopenic patients based on prognosis. RESULTS Of the 135 patients, 35 were diagnosed with sarcopenia and 100 were not. We combined the creatinine and albumin levels (Cr × Alb) as a stratifying marker for sarcopenia, and extracted sarcopenic patients with values below the Cr × Alb cut-off as the actual sarcopenic group. The 5-year overall survival (OS) rates of the actual and non-actual sarcopenic groups were 28.9% and 58.9%, respectively (p = 0.0005), and the 5-year disease-free survival rate of the actual sarcopenic group was 34.1%, and 62.8% (p = 0.0106) for the non-actual sarcopenic group. This stratified sarcopenia model was an independent prognostic factor and was superior to sarcopenia alone for OS. CONCLUSIONS In patients undergoing MIE, preoperative measurement of Cr × Alb may be a prognostic stratification marker for patients with sarcopenia.

Abstract
OBJECTIVES This retrospective study was designed to investigate the optimal extent of dissection for thoracic esophageal cancer (EC) based on the incidence of lymph node metastasis (LNM). METHODS We retrospectively identified 1014 patients with thoracic esophageal carcinoma who underwent esophagectomy at our institution between May 2018 and November 2020. Also, the location and rate of LNM in relation to the postoperative pathological results were retrieved. We separately counted the metastasis rates of routinely excised lymph node stations according to the Japan Esophageal Society (JES) staging system. RESULTS A total of 1666 consecutive patients were screened, and 1014 were enrolled. Generally, the rates of LNM in thoracic EC may be arranged in the descending order of station 7 > station 106recR > station 2 > station 106recL. Esophageal cancer in the middle and lower thoracic segment also had a high rate of LNM along bilateral recurrent laryngeal nerve. Stations 106tbL and 111 were the lowest frequent sites of metastasis with rate less than 5%; only the patients with clinically positive LNs need to dissect. The cT3-4, cN+, or G3 were independent risk factors for LNM and neoadjuvant therapy did not change the distribution of LNM for thoracic EC cases. CONCLUSIONS This study accurately identified the distribution of LNM for thoracic EC patients. Neoadjuvant therapy could not change the overall distribution of LNM in thoracic EC patients. However, whether LNs dissection at stations 106tbL and 111 is related to the survival of thoracic EC or not, needs a long follow-up time to verify.

Advantages of McKeown minimally invasive oesophagectomy for the treatment of oesophageal cancer: propensity score matching analysis of 169 cases. World J Surg Oncol 2022; 20:52.

Abstract
BACKGROUND Oesophagectomy, the gold standard for oesophageal cancer treatment, causes significantly high morbidity and mortality. McKeown minimally invasive oesophagectomy (MIE) is preferred for treating oesophageal malignancies; however, limited studies with large sample sizes focusing on the surgical and oncological outcomes of this procedure have been reported. We aimed to compare the clinical safety and efficacy of McKeown MIE with those of open oesophagectomy (OE). PATIENTS AND METHODS Overall, 338 oesophageal cancer patients matched by gender, age, location, size, and T and N stages (McKeown MIE: 169 vs OE: 169) were analysed. The clinicopathologic features, operational factors, postoperative complications, and prognoses were compared between the groups. RESULTS McKeown MIE resulted in less bleeding (200 mL vs 300 mL, p<0.01), longer operation time (335.0 h vs 240.0 h, p<0.01), and higher number of harvested lymph nodes (22 vs 9, p<0.01) than OE did. Although the rate of recurrent laryngeal nerve injury in the two groups was not significantly different, incidence of anastomotic leakage (8 vs 24, p=0.003) was significantly lower in the McKeown MIE group. In addition, patients who underwent McKeown MIE had higher 5-year overall survival than those who underwent OE (69.9% vs 40.4%, p<0.001). CONCLUSION McKeown MIE is proved to be feasible and safe to achieve better surgical and oncological outcomes for oesophageal cancer compared with OE.

Abstract
BACKGROUND/AIMS We aimed to study the clinical characteristics, treatment modality, and the prognosis of synchronous multiple primary esophageal squamous cell carcinomas (SMPESCC). METHODS A total of 117 SMPESCC cases were evaluated retrospectively from 2010 to 2015. RESULTS The most common locations of SMPESCC were mid- and lower thoracic segments (n = 208, 84.9%). The 1-, 2-, and 3-year overall survival rates were 53.8%, 30.8%, and 15.4%, respectively; the median survival time (MST) was 12.5 months. With definitive radiotherapy and surgery, respectively, the MST of stage I/II patients were 34.2 and 26.7 months, of stage III patients were 8.3 and 13.2 months (p = 0.163), and of stage IV patients were and 8 and 12.6 months (p = 0.379). Clinical stage, family history of cancer, and Karnofsky performance status were independent prognostic factors for the whole cohort by Cox multivariate regression analysis (hazard ratio [HR] = 0.859, p < 0.001; HR = 0.579, p = 0.032; and HR = 0.586, p = 0.013). CONCLUSION Although the prognosis of SMPESCC is poor, stage I/II patients can achieve long-term survival with aggressive treatment, especially those with a Karnofsky performance score 90 or higher and who have no family history of cancer. Definitive radiotherapy could achieve a similar survival rate to definitive surgery at different clinical stages.

Abstract
BACKGROUND Most anastomotic leaks after surgical resection for esophageal or esophagogastric junction malignancies are treated endoscopically with esophageal stents. Internal drainage by double pigtail stents has been used for the endoscopic management of leaks following bariatric surgery, and recently introduced for anastomotic leaks after resections for malignancies. Our aim was to assess the overall efficacy of the endoscopic treatment for anastomotic leaks after esophageal or gastric resection for malignancies. METHODS We conducted a multicenter retrospective study in four digestive endoscopy tertiary referral centers in France. We included consecutive patients managed endoscopically for anastomotic leak following esophagectomy or gastrectomy for malignancies between January 2016 and December 2018. The primary outcome was the efficacy of the endoscopic management on leak closure. RESULTS Sixty-eight patients were included, among which 46 men and 22 women, with a mean ± SD age of 61 ± 11 years. Forty-four percent had an Ivor Lewis procedure, 16% a tri-incisional esophagectomy, and 40% a total gastrectomy. The median time between surgery and the diagnosis of leak was 9 (6-13) days. Endoscopic treatment was successful in 90% of the patients. The efficacy of internal drainage and esophageal stents was 95% and 77%, respectively (p = 0.06). The mortality rate was 3%. The only predictive factor of successful endoscopic treatment was the initial use of internal drainage (p = 0.002). CONCLUSION Endoscopic management of early postoperative leak is successful in 90% of patients, preventing highly morbid surgical revisions. Internal endoscopic drainage should be considered as the first-line endoscopic treatment of anastomotic fistulas whenever technically feasible.

Abstract
BACKGROUND Esophageal cancer (EC) is a malignant tumor with high mortality. Nomogram is an important tool used in clinical prognostic assessment. We aimed to establish a novel nomogram to predict the overall survival (OS) of EC patients after radical esophagectomy. METHODS Data pertaining to the survival, demography, and clinicopathology of 311 EC patients who underwent radical esophagectomy were retrospectively investigated. The nomogram was established based on Cox hazard regression analysis. The calibration curves and Harrell's concordance index (C-index) were used to verify the predictive accuracy and ROC curves were used to assess the efficacy of the nomogram. Kaplan-Meier curves showed the prognostic value of the related risk classification system. Pearson correlation test was performed to determine the correlation between the risk classification system and TNM staging. RESULTS The median OS and 5-year survival rates in the primary and validation cohorts were 44 months and 29.8%, and 52 months and 27.1%, respectively. We used six independent prognostic factors-age, Sex, AGR, PRL, N stage, and PNI-in the nomogram. The C-index of nomogram was 0.75 and 0.70 in the primary and validation cohorts, respectively. Calibration curves indicated high consistency between actual and predicted OS. ROC curves showed that nomogram has a better efficacy compared with TNM staging in both cohorts. Patients were divided into three risk groups according to the total nomogram score, the median OS in each group was significantly different in both cohorts. Furthermore, the risk classification system was strongly correlated with the T and N staging system and exhibited a better OS prediction capability. CONCLUSIONS We established a novel and practical nomogram with a subordinate risk classification system to predict the OS of patients after radical esophagectomy. Compared with AJCC staging, this nomogram had preferable clinical capability in terms of individual prognosis assessment.

Quantity and Quality of Skeletal Muscle as an Important Predictor of Clinical Outcomes in Patients with Esophageal Cancer Undergoing Esophagectomy after Neoadjuvant Chemotherapy. Ann Surg Oncol 2021; 28:7185-7195. [PMID: 33876359 DOI: 10.1245/s10434-021-10025-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 03/27/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Sarcopenia was previously linked to clinical outcomes for several cancer types, including esophageal cancer (EC), but most studies only measured the quantity of skeletal muscle mass. We aim to assess the clinical significance of evaluating the quantity and quality of skeletal muscle in patients with EC who underwent neoadjuvant chemotherapy (NAC) followed by esophagectomy. METHODS We included 333 consecutive patients with EC who underwent NAC followed by esophagectomy. The psoas muscle index (PMI) and intracellular muscle adipose tissue content (IMAC) were measured by computed tomography. We defined low PMI combined with high IMAC as severe sarcopenia, and assessed its impact on clinical outcomes. RESULTS Thirty-seven patients (11.1%) had severe sarcopenia. Compared with patients without severe sarcopenia, those with severe sarcopenia showed a significantly worse NAC response rate (54.1% vs 74.7%; P = 0.008), worse pathological response rate (24.3% vs 40.2%, P = 0.061), higher morbidity rate (67.6% vs 38.5%; P = 0.001), particularly for pneumonia (32.4% vs 14.9% P = 0.007) and expectoration disorder (37.8% vs 13.5% P < 0.001), and unfavorable survival (3-year overall survival rate: 54.1% vs 66.6% P = 0.027). Multivariable analysis of overall survival showed that severe sarcopenia (HR 1.68, P = 0.025) and cT (HR 1.52, P = 0.032) were independent prognostic factors of poor outcome. CONCLUSIONS PMI combined with IMAC represents a new criterion for sarcopenia that might be useful for predicting NAC response, postoperative complications, and long-term survival in patients with EC undergoing multidisciplinary treatments.

Proposed Modification of the pN2 Classification of the 8th Edition AJCC Staging System for Esophageal Squamous Cell Carcinoma: A Preliminary Study Based on the Chinese Population. JOURNAL OF ONCOLOGY 2021; 2021:8871884. [PMID: 33777143 PMCID: PMC7972858 DOI: 10.1155/2021/8871884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 01/24/2021] [Accepted: 02/08/2021] [Indexed: 11/17/2022]
Abstract
Objective To evaluate the efficacy of the nodal staging of the 8th edition AJCC staging system for esophageal squamous cell carcinoma (ESCC) and propose a modification of the current pN2 classification. Methods 1188 patients who underwent esophagectomy for ESCC at Sun Yat-sen University Cancer Center in Guangzhou (Guangdong, China) between January 2005 and June 2010 were reviewed. We used the X-tile software to determine the optimal cutoff points. Kaplan–Meier method and log-rank test were used to compare the differences of survival. Multivariate Cox regression analysis was performed for the factors that were statistically significant in univariate analysis. Result In multivariate Cox regression analysis, alcohol consumption, pT status, and pN status were independent prognostic factors for overall survival (OS) according to the current pN classifications. And the observed 5-year OS rates for groups pN0, pN1, pN2, pN3 were 66.7%, 45.0%, 31.5%, and 21.5%, respectively (P<0.001). Based on the above results, the current pN2 classification was further subdivided as pN2a [3 metastatic lymph nodes (LNs)] and pN2b (4−6 metastatic LNs) groups. The 5-year OS rates for groups pN0, pN1, pN2a, pN2b, and pN3 were 66.7%, 45.0%, 37.7%, 26.3% and 21.5%, respectively (P<0.001). The rate of 5-year disease-free survival (DFS) was 60.0% for patients with pN0, compared with 36.8%, 29.3%, 20.8%, and 14.3% for those with pN1, pN2a, pN2b, and pN3, respectively (P<0.001).The current pN2 classification should be subdivided as pN2a (3 metastatic LNs) and pN2b (4–6 metastatic LNs) groups. The modified pN2 classification could better discriminate the survival differences between patients with 3–6 metastatic LNs for ESCC in the Chinese population.

The Prognostic Value of Log Odds of Positive Lymph Nodes in Early-Stage Esophageal Cancer Patients: A Study Based on the SEER Database and a Chinese Cohort. JOURNAL OF ONCOLOGY 2021; 2021:8834912. [PMID: 33747080 PMCID: PMC7954630 DOI: 10.1155/2021/8834912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 12/19/2020] [Accepted: 02/02/2021] [Indexed: 12/09/2022]
Abstract
Objective Early detection and timely treatment are important for improving the prognosis of esophageal cancer (EC). Identification of the prognostic risk factors could help us to discern the high-risk population. This study was aimed at exploring the prognostic significance of log odds of positive lymph nodes (LODDS) in early-stage EC patients. Methods Patients who underwent esophagectomy and diagnosed as pathologic T1-2 N0 EC were reviewed between January 2005 and December 2015 from the Surveillance, Epidemiology, and End Results (SEER) database (the development cohort, n = 1004). The X-tile software was used to determine the optimal cutoff values of LODDS. A separate Chinese cohort including 245 patients (the validation cohort) was used to externally validate the results of the SEER database. Result Patients were divided into two groups based on the cutoff points of LODDS: <-1.40 (LODDS1) and ≥-1.40 (LODDS2). In the development cohort, the 5-year overall survival (OS) rate was 75.3% for patients in the LODDS1 group, compared with 67.5% for those in the LODDS2 group (P=0.002). In multivariate Cox analysis, LODDS was associated with OS significantly (hazard ratio (HR), 1.48; 95% confidence intervals (CI), 1.19-1.85). In the validation cohort, the 5-year OS rate was 76.6% for patients in the LODDS1 group, compared with 64.4% for those in the LODDS2 group (P=0.006). The HR value in multivariate Cox analysis for OS was 2.00 (95% CI, 1.26-3.18). Conclusion LODDS was an important independent factor for survival in early-stage EC patients.

Abstract
BACKGROUND After esophagectomy, various reconstruction routes can be considered for technical and oncologic objectives. The substernal route is believed to cause more dysphagia or delayed gastric emptying symptoms than the posterior mediastinal route. We evaluated and compared the quality of life (QoL) after reconstruction by either the substernal or posterior mediastinal routes in the McKeown procedure. METHODS Between 2011 and 2018, 378 patients who received an esophagectomy and cervical esophagogastrostomy for esophageal cancer were followed up. Among these patients, 278 received reconstruction via the substernal route and 100 via the posterior mediastinal route. Patients completed the validated questionnaires, EORTC QLQ-C30 and QLQ-OES18, before surgery and at 1, 2, 3, 6, 12, and 24 months after surgery. Linear mixed-effects models were used to examine changes in questionnaire scores over time. RESULTS One month after surgery, patients QoL deteriorated and more symptoms were observed than at baseline. Global health status, nausea and vomiting, and esophageal pain gradually recovered from 2 months and recovered to initial levels at 2 years. However, the other functional and symptom scales of the QLQ-C30 and OES18 were not normalized at 2 years after the operation. When comparing the substernal and posterior mediastinal routes, QLQ-OES18 symptom scales, such as eating, dysphagia, trouble with swallowing saliva trouble with taste and reflux, were no different between the two groups, even after adjusting confounding factors at 2 years after the operation. CONCLUSION The cervical esophagogastrostomy with a substernal route showed comparable QoL to reconstruction with a posterior mediastinal route.

Abstract
Background The purpose of this study was to explore the prognostic factors of oesophageal signet ring cell (SRC) carcinoma and to construct a nomogram for predicting the outcome of SRC carcinoma of oesophagus. Methods A total of 968 cases of oesophageal SRC carcinoma were extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2016. Cases were divided into training cohort and validation cohort. Univariate and multivariable Cox analyses was performed to select the predictors of overall survival (OS for the nomogram. The performance of nomogram was validated with Harrell’s concordance index (C-index), calibration curves and decision curve analysis (DCA). Results The 1- and 5-year OS in the training cohort were 0.446 and 0.146, respectively, and the 1- and 5-year OS in the validation cohort were 0.459 and 0.138. The independent prognostic factors for establishing the nomogram were marital status, invasion of the surrounding tissue, lymph node metastasis, distant metastasis, surgery and chemotherapy. The Harrell’s c-index value of the training cohort and validation cohort were 0.723 and 0.708. In the calibration curves, the predicted survival probability and the actual survival probability have a considerable consistency. DCA indicated the favourable potential clinical utility of the nomogram. Conclusions A nomogram to predict the OS of patients with oesophageal SRC carcinoma was established. The validation of the nomogram fully demonstrates its great performance.

Abstract
INTRODUCTION Transhiatal esophagectomy (THE) was popularized to reduce the morbidity of esophagectomy. Thoracoscopy-assisted esophagectomy (TAE) offers esophageal dissection under magnified vision. This study compares the short-term morbidity and oncological outcome following TAE and THE for esophageal carcinoma. METHODOLOGY This is a prospective comparative (January 2017-May 2018) study between TAE and THE for >cT1bN1 esophageal carcinoma. After neoadjuvant chemoradiotherapy (NACRT), responders and patients with stable diseases were subjected to surgery. Thoracoscopy in esophagectomy was performed in prone position. Follow-up duration was at least 4 weeks post-discharge. RESULTS Thirty-three patients of esophageal carcinoma undergoing TAE (n = 18) or THE (n = 15) were included. Common locations of tumor were lower third of esophagus (72.7%) and esophagogastric junction (18.2%). Majority (73.3%) had squamous cell carcinoma. Median interval between NACRT and surgery was 13 weeks. The mean operating time was significantly more with TAE than THE (292.5 vs 207.33 min, p = 0.005). R0 resection rate in TAE was 83.3% compared with 66.7% in THE. There was no difference in the lymph node yield. There was non-significant trend towards lower incidence of major pulmonary complication (66.7% vs 80.0%), cardiac complications (27.8% vs 46.7%), anastomotic leak (27.8% vs 46.7%), recurrent laryngeal nerve palsy (16.7% vs 20.0%), and overall major morbidity (Clavien-Dindo ≥ III) (44.4% vs 66.7%) in TAE than THE. The chyle leak was observed more in TAE (16.7%) than THE (6.7%). CONCLUSIONS TAE achieved higher R0 resection rate and better short-term morbidity than THE. Enrollment of small number of cases in the study precluded statistical significance. TRIAL REGISTRATION This study was registered in Clinical Trial Registry-India (CTRI registration no: CTRI/2018/05/013880) in 14-05-2018.

Abstract
Background Minimally invasive oesophagectomy (MIO) is reported to produce fewer respiratory complications than open oesophagectomy. This study assessed differences in postoperative complications between MIO and hybrid MIO (HMIO) employing thoracoscopy and laparotomy, along with the influence of co-morbidities on postoperative outcomes. Methods Patients with oesophageal cancer undergoing three-stage MIO or three-stage HMIO between 1999 and 2018 were identified from a prospectively developed database, which included patient demographics, co-morbidities, preoperative therapies, and cancer stage. The primary outcome was postoperative complications in the two groups. Secondary outcomes included duration of operation, blood transfusion requirement, duration of hospital stay, and overall survival. Results There were 828 patients, of whom 722 had HMIO and 106 MIO, without significant baseline differences. Median duration of operation was longer for MIO (325 versus 289 min; P < 0.001), but with less blood loss (median 250 versus 300 ml; P < 0.001) and a shorter hospital stay (median 12 versus 13 days; P = 0.006). Respiratory complications were not associated with operative approach (31.1 versus 35.2 per cent for MIO and HMIO respectively; P = 0.426). Anastomotic leak rates (10.4 versus 10.2 per cent) and 90-day mortality (1.0 versus 1.7 per cent) did not differ. Cardiac co-morbidity was associated with more medical and surgical complications. Overall survival was associated with AJCC stage and co-morbidities, but not operative approach. Conclusion MIO had a small benefit in terms of blood loss and hospital stay, but not in operating time. Oncological outcomes were similar in the two groups. Postoperative complications were associated with pre-existing cardiorespiratory co-morbidities rather than operative approach.

Abstract
Background Although previous studies have discussed whether the minimally invasive esophagectomy (MIE) is superior to open surgery, the data concerning esophageal squamous cell carcinoma (ESCC) patients underwent neoadjuvant treatment followed by radical resection is limited. The purpose of our study was to compare the short- and long-term clinical outcomes of the two surgical approaches in treating ESCC patients. Methods Between January 2010 and December 2016, ESCC patients who had received neoadjuvant therapy and underwent Mckeown esophagectomy at our institute were eligible. The baseline characteristics, pathological data, short-and long-term outcomes of these patients were collected and compared based on the surgical approach. Results A total of 195 patients was included in the current study. Compared to patients underwent open surgery, patients underwent MIE had shorter operative time and less intraoperative bleeding (390 min vs 330 min, P = 0.001; 204 ml vs 167 ml, P = 0.021). In addition, the risk of anastomotic leakage was decreased in MIE group (20.0% vs 3.3%, P < 0.001), while the occurrence of other complications did not have statistical significance between two groups. Overall survival (OS) and disease-free survival (DFS) was no difference in patients received neoadjuvant chemotherapy between the two approaches. For the patients underwent neoadjuvant chemoradiotherapy, OS was significantly better in the MIE group (log rank = 6.197; P = 0.013). Conclusion Minimally invasive Mckeown esophagectomy is safe and feasible for ESCC patients who underwent neoadjuvant therapy. MIE approach presented better perioperative results than open esophagectomy. The effect of surgical approaches on survival was depending on the scheme of neoadjuvant treatment.

Esophageal squamous cell carcinoma metachronous to head and neck cancers. Pathol Res Pract 2021; 219:153346. [PMID: 33545655 DOI: 10.1016/j.prp.2021.153346] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 01/14/2021] [Accepted: 01/15/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND In some HNSCC patients, a metachronous ESCC may develop. No information is available on the HNSCC-associated ESCCs microenvironment and etiology. METHODS Among 134 ESCCs surgically treated between 2009 and 2015, a series of 6 HNSCC-associated ESCCs was collected. A series of 12 sex-, age- and stage-matched ESCCs with no previous oncological medical history was selected for comparison. Histologic assessment of intratumoral inflammatory infiltration and immunohistochemistry for CD4, CD8, CD80, PD1, PD-L1 and p53 were performed. HPV detection/genotyping was assessed by PCR single step and reverse line blot. RESULTS HPV DNA was negative in all the HNSCC-associated ESCCs. In comparison to non-HNSCC-associated carcinomas, the 6 cases presented a lower lymphomonocytic infiltration, which also corresponded to a lower prevalence of CD4 + T cell infiltration and, 5/6 cases presented a PD-L1 CPS ≥ 1. All the HNSCC-associated ESCCs resulted positive for p53 immunostaining in ≥50 % of cancer cells. CONCLUSION Our study suggests that HPV infection is not an etiological factor associated to ESCC after HNSCC. On the other hand, p53 overexpression is a common finding. Moreover, our data suggest that an altered immune microenvironment, conditioned by a dysregulation in lymphomonocytic infiltration, may be a crucial factor allowing the occurrence of a metachronous ESCC.

Abstract
Objective To compare the effectiveness of the current N classification and a modified N2 categorization in TNM staging of esophageal cancer (EC) patients. Methodology A total of 2753 EC patients were enrolled in the study: 2283 EC patients from the Surveillance, Epidemiology, and End Results (SEER) database and 470 separate Chinese patients were used to verify the results of the SEER database. X-tile software was employed to determine the optimal cutoff points of the number of metastatic lymph nodes (LNs) in the N2 category. Univariate and multivariate Cox regression analyses were performed to identify the survival risk factors. Result Patients in the N2 category were divided into two groups based on the number of metastatic LNs. Patients with three and four metastatic LNs were categorized as N2a, while those with five and six metastatic LNs were categorized as N2b. The 3-year overall survival (OS) rate in the SEER database was 71.5%, 42.3%, 23.6%, 17.2%, and 10.7% for patients with N0, N1, N2a, N2b, and N3, respectively (P<0.001). Furthermore, a separate Chinese cohort was enrolled to validate the revised N2 category. Additionally, the 3-year OS rate was 71.5%, 42.3%, 23.6%, 17.2%, and 10.7% for patients with N0, N1, N2a, N2b, and N3, respectively (P<0.001). Conclusion The current N2 category should be further divided into two groups (N2a and N2b) to provide more accurate prognosis information that could further help in developing personalized therapeutic strategies.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a highly malignant and deadly tumor. Radiation therapy is one of the primary treatments for locally advanced ESCC. However, the biomarkers for prognosis of definitive radiation remain undefined. Peripheral blood circulating tumor (ct)DNA provides information of tumor genetic alterations and has been confirmed as a potential non-invasive biomarker for several types of cancer. The present study investigated the clinical implications of ctDNA detection in patients with ESCC and receiving definitive radiation therapy. Patients with locally advanced ESCC were retrospectively recruited. Plasma samples were collected before, during and following radiation therapy. Next-generation sequencing was performed to identify somatic mutations in 180 genes. A total of 69 baseline and post-radiation plasma samples were collected from 25 patients. A total of 59 non-silent single nucleotide variants were present in 33 genes. All pre-radiation and 58.3% (14/24) of post-radiation samples had at least one mutation. Patients with lymph node metastases (LNM) exhibited a higher number of pre-radiation mutations compared with those without LNM. The variables, progression-free survival (PFS) and overall survival (OS) of the patients with one baseline mutation were not significantly different compared with that in patients with more than one baseline mutation. Patients with initial ctDNA-positive post-radiation samples exhibited significantly reduced PFS (P=0.047) and OS (P=0.005) compared with that in patients with ctDNA-negative samples. The post-radiation plasma ctDNA status was an independent prognostic factor from univariate and multivariate analyses. Dynamic monitoring of ctDNA during follow-up was examined. The results indicated that ctDNA was a predictive and prognostic marker in patients with ESCC and receiving definitive radiation therapy, which may guide subsequent treatment.

Ann Thorac Surg 2020; 112:928-934. [PMID: 33152329 DOI: 10.1016/j.athoracsur.2020.09.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Revised: 09/15/2020] [Accepted: 09/23/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Minimally invasive esophagectomy (MIE) has been used widely for the treatment of esophageal cancer. However, there is still a lack of consensus on the extent of lymphadenectomy in MIE. The objective of this study was to investigate the safety and efficacy of three-field lymphadenectomy (3-FL) in MIE, compared with the standard two-field lymphadenectomy (2-FL). METHODS A single-center randomized controlled trial was conducted, enrolling patients with resectable thoracic esophageal cancer (cT1-3,N0-3,M0) between June 2016 and May 2019. Eligible patients were randomized into two groups to receive either 3-FL or 2-FL during MIE procedures. Perioperative outcomes of the two groups were compared. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-INR-16007957). RESULTS Seventy-six eligible patients were randomly assigned to the 3-FL group (n = 38) and the 2-FL group (n = 38). Compared with patients in the 2-FL group, patients in the 3-FL group had more lymph nodes harvested (54.7 ± 16.5vs 30.9 ± 9.6, P < .001) and more metastatic lymph nodes identified (3.5 ± 4.5 vs 1.7 ± 2.0, P = .027). Patients in the 3-FL group were diagnosed with a more advanced final pathologic TNM stage than patients in the 2-FL group. There was no significant difference between the two groups in blood loss, major postoperative complications, or duration of hospital stay, except that the operation time was longer in the 3-FL group than in the 2-FL group (270.5 ± 45.4 minutes vs 236.7 ± 47.0 minutes, P = .002). CONCLUSIONS Three-field lymphadenectomy allowed harvesting of more lymph nodes and more accurate staging without increased surgical risks compared with 2-FL MIE for esophageal cancer.

Abstract
Gastroesophageal reflux is a common problem after gastroesophageal resection and reconstruction, despite the routine prescription of proton pump inhibitors (PPIs). Resection of the lower esophageal sphincter and excision of the vagus nerve are generally thought to be the main factors that interfere with gastric motor function. However, physiological studies of reflux symptoms after esophagectomy are still lacking. Gastroesophageal reflux occurs frequently after esophagectomy, but there is no known effective method to prevent it. Therefore, in order to manage gastroesophageal reflux after esophagectomy, strict lifestyle modifications and gastric acid suppression treatment such as PPIs are needed, and further clinical studies are required.

Abstract
INTRODUCTION The usage of a feeding jejunostomy has been a well-established practice in maintaining nutrition in patients undergoing resections for upper gastrointestinal cancer. As surgical technique has evolved, together with the adoption of enhanced recovery after surgery pathways, the routine insertion of feeding jejunostomy tubes appears to be changing. MATERIALS AND METHODS A survey was constructed using Google Forms. The link was distributed to consultant upper gastrointestinal surgeons via the Association of Upper Gastrointestinal Surgeons' membership database. Results were collated and analysed using Microsoft Excel. RESULTS A total of 55 responses were received from 28 units across the UK; 27 respondents (49.1%) no longer routinely use feeding jejunostomy in upper gastrointestinal resections, oesophagectomy or gastrectomy. The most common primary feeding modality used by these respondents was oral diet 17 (65.4%), with total parenteral nutrition (19.2%) and nasojejunal (11.5%) routes also being used. Respondents who used feeding jejunostomies inserted them primarily for oesophagectomy (n = 27; 96.4%), with fewer surgeons using them in extended total gastrectomy (n = 12; 42.9%) and total gastrectomy (n = 11; 39.3%). Of the total, 20 surgeons (71.4%) would insert the jejunostomy using an open approach, with 19 (67.9%) employing a Witzel tunnel. Eleven respondents (39.3%) would continue feeding via the jejunostomy after discharge. Some 24 responders thought that feeding jejunostomies did not facilitate the enhanced recovery after surgery pathway (strongly and slightly disagree), whereas 17 considered that they did (strongly and slightly agree); 13 responders did not have strong views either way. CONCLUSIONS There is a split in current practice regarding the usage of feeding jejunostomies. There is also a division of opinion on the role of feeding jejunostomy in enhanced recovery after surgery.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a common malignancy worldwide. The disease has a poor prognosis and a low 5-year survival rate. Therefore, it is necessary to identify new strategies to optimize the treatment of ESCC. Vaccinia-related kinase (VRK1) and barrier-to-autointegration factor 1 (BANF1) are overexpressed in ESCC. In the present study, the roles of VRK1 and BANF1 were explored in the development of ESCC. In the present study, the effects of small interfering (si)RNA-induced downregulation of VRK1 on BANF1 expression were investigated as well as the effects on proliferative and migratory activity of ESCC cells. Western blot analysis indicated that the protein expression levels of BANF1 were decreased following siRNA depletion of VRK1. Furthermore, the depletion of VRK1 expression inhibited the proliferation and migration of ESCC cell lines, and flow cytometry analysis indicated that the depletion of VRK1 triggered cell cycle arrest mainly in the S phase. These results suggested that VRK1 and BANF1 may have pivotal roles in the progression of ESCC.

Abstract
BACKGROUND The surgery for esophageal cancer arising after prior gastrectomy is technically difficult with high morbidity and mortality. Endoscopic submucosal dissection (ESD) is a minimally invasive endoscopic treatment for superficial SCC with high curative resection rate. But few studies are concerned about ESD under these circumstances. The aim of this study was to elucidate the short- and long-term outcomes of ESD for superficial esophageal squamous cell cancer (SCC) in patients with prior gastrectomy. METHODS From January 2009 to January 2019, 37 patients with prior gastrectomy who underwent ESD for superficial esophageal SCC were retrospectively enrolled at the Zhongshan Hospital, Fudan University in Shanghai, China. Rates of en bloc resection, complete resection, curative resection, incidence of postoperative bleeding, perforation and postoperative stricture were evaluated as short-term outcomes. Overall survival, and local recurrence-free survival were evaluated as long-term outcomes. RESULTS The rate of en bloc resection, complete resection and curative resection were 94.6%, 86.5% and 78.4%, respectively. No perforation was observed. 1 (2.7%) patient experienced postoperative bleeding. During the median observation of 43 months, 3 (8.6%) patients experienced esophageal stricture, successfully managed by balloon dilation. 3(8.6%) patients had local recurrence after ESD with 5-year local recurrence-free survival rate of 91.4%. During the observation period, 4 patients died of other reasons. The 1, 3, 5-year overall survival rates were 97.1%, 97.1% and 91.4%. CONCLUSIONS The short-term outcomes indicate ESD is technically difficult with lower resection completeness in patients after gastrectomy, while the long-term outcomes are rather favorable.

Abstract
Although esophageal cancers have poor survival outcomes, evidence suggests that preoperative chemoradiation followed by surgery have improved survival outcomes. Minimally invasive surgery has equivalent oncological outcomes with less complication compared with open surgery, but there is insufficient data available in South Indian population. Our aim was to analyze the perioperative outcome and survival between minimally invasive and open transhiatal esophagectomy group. Data from patients operated for esophageal cancer in our department from the year 2015 to 2018 were collected retrospectively using medical records. Among 55 carcinoma esophagus patients, squamous histology (67%) and lower third location (57%) being predominant. Twenty-six patients underwent video-assisted thoracoscopic surgery (VATS)-assisted esophagectomy and 18 patients underwent open transhiatal esophagectomy. Eleven patients were inoperable. Sixteen patients in VATS arm and three patients in transhiatal arm received preoperative chemoradiation. VATS arm has lesser intraoperative blood loss, early pulmonary recovery with early intercostal drain removal, and lesser hospital stay but longer mean operating time of 171 min versus 140 min (P < 0.01). It has higher mean nodal harvest of 15 versus 7 nodes (P 0.01) and higher overall median survival of 36 months (95% CI, 29.3 to 42.7) as against 23 months (95% CI, 17.8 to 29.2) for transhiatal arm (P < 0.01). VATS-assisted esophagectomy is less morbid procedure with early postoperative recovery, better oncological outcomes, and improved survival compared with transhiatal arm which is equivalent to apex centers in India.

Abstract
BACKGROUND Some studies have reported that sarcopenia is linked to clinical outcomes in multiple types of malignancies, but this association has not been established in esophageal cancer. We assessed how sarcopenia affects clinical outcomes of multidisciplinary treatments for esophageal cancer. METHODS We included 165 esophageal cancer patients who had undergone neoadjuvant chemotherapy followed by esophagectomy. Computed tomography was used for cross-sectional measurement of the psoas muscle at the third lumbar vertebra; we then calculated the height-adjusted psoas muscle index. Pre- and postneoadjuvant chemotherapy psoas muscle indices were evaluated for associations with neoadjuvant chemotherapy response and neoadjuvant chemotherapy -related adverse events and postoperative complications, in addition to survival. Psoas muscle index cutoffs were 6.36 cm2/m2 for men and 3.92 cm2/m2 for women. RESULTS Psoas muscle index decreased after neoadjuvant chemotherapy (from 7.17 to 6.96 cm2/m2; P = .0008), and specifically in men (from 7.45 to 7.23 cm2/m2; P = .0001) but not in women (from 5.21 to 5.17 cm2/m2; P = .810). Preneoadjuvant chemotherapy psoas muscle index (low versus high) was associated with neoadjuvant chemotherapy response (response rate: 65.1% vs 80.3%; P = .0494) and neoadjuvant chemotherapy-related adverse events (neutropenia: 93.0% vs 78.7%; P = .0337; febrile neutropenia: 53.5% vs 34.3%; P = .0278; hyponatremia: 51.2% vs 31.2%; P = .0190). Post-neoadjuvant chemotherapy psoas muscle index correlated with postoperative rate of complications (56.9% vs 33.3%; P = .0046), especially pneumonia (31.4% vs 9.7% P = .0008). Psoas muscle index was not associated with survival. CONCLUSION Cross sectional measures of sarcopenia before and after neoadjuvant chemotherapy could predict tumor response, neoadjuvant chemotherapy -related adverse events, and postoperative complications in multidisciplinary treatments for esophageal cancer.

PD-L1 expression, CD8+ and CD4+ lymphocyte rate are predictive of pathological complete response after neoadjuvant chemoradiotherapy for squamous cell cancer of the thoracic esophagus. Cancer Med 2019; 8:6036-6048. [PMID: 31429521 PMCID: PMC6792480 DOI: 10.1002/cam4.2359] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 04/28/2019] [Accepted: 06/03/2019] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (CTRT) can effectively downstage esophageal squamous cell carcinoma (SCC) in patients with locally advanced disease and prolonged survival have been observed in patients with a pathological complete response (ypCR). AIMS AND METHODS This exploratory study aimed to identify immunological predictors of pCR after neoadjuvant CTRT within SCC microenvironment. The tumor regression after neoadjuvant therapy was measured according to the Mandard score system. Eighty-eight consecutive patients with SCC of the thoracic esophagus who received neoadjuvant CTRT were included in this retrospective study. Inclusion criteria were neoadjuvant CTRT and the availability of representative histological samples taken at diagnosis. We investigated immunohistochemical expression of CD4, Tbet, FoxP3, CD8, CD80, PD-L1, and PD-1, in the pretreatment biopsies and correlated the immunohistochemical profiles to patients' outcomes. RESULTS After neoadjuvant CTRT, 23 patients had pCR, while 65 ones had partial response, stable disease or progression. PD-L1 expression and CD8+ and CD4+ lymphocyte rate were significantly higher in patients who had ypCR compared to those who had not (10 (0-55) vs 0 (0-0), P = 0.004, 73 (36-147) vs 21 (7-47), P = 0.0006 and 39 (23-74) vs 5 (0-13), P < 0.0001 respectively). The accuracy of expression of PD-L1+, CD8+, and CD4+ lymphocyte rate in identifying responders was AUC = 0.76 (P = 0.001), AUC = 0.81 (P = 0.0001) and AUC = 0.75 (P = 0.0001), respectively. Within the ypCR group, all patients with high infiltration of CD4+ T cell recurred/relapsed while only the 38.9% of those with low CD4+ T cell infiltration did the same (P = 0.058). CONCLUSIONS PD-L1 expression and CD8+ and CD4+ lymphocyte rate were predictive of ypCR after neoadjuvant CTRT for SCC of the thoracic esophagus with adequate accuracy. Furthermore, recurrence/relapse was associated with high level of CD4+ T cell infiltration. However, the small sample size prevented to draw definitive conclusions; further studies are necessary to evaluate the prognostic role of these markers.

Abstract
BACKGROUND Standard therapy for loco-regionally advanced, resectable oesophageal carcinoma is trimodality therapy (TMT) consisting of neoadjuvant chemoradiotherapy and oesophagectomy. Evidence of survival advantage of TMT over organ-preserving definitive chemoradiotherapy (dCRT) is inconclusive. The aim of this study is to compare survival between TMT and dCRT. METHODS A systematic review and meta-analyses were conducted. Randomised controlled trials and observational studies on resectable, curatively treated, oesophageal carcinoma patients above 18 years were included. Three online databases were searched for studies comparing TMT with dCRT. Primary outcomes were 1-, 2-, 3- and 5-year overall survival rates. Risk of bias was assessed using the Cochrane risk of bias tools for RCTs and cohort studies. Quality of evidence was evaluated according to Grading of Recommendation Assessment, Development and Evaluation. RESULTS Thirty-two studies described in 35 articles were included in this systematic review, and 33 were included in the meta-analyses. Two-, three- and five-year overall survival was significantly lower in dCRT compared to TMT, with relative risks (RRs) of 0.69 (95% CI 0.57-0.83), 0.76 (95% CI 0.63-0.92) and 0.57 (95% CI 0.47-0.71), respectively. When only analysing studies with equal patient groups at baseline, no significant differences for 2-, 3- and 5-year overall survival were found with RRs of 0.83 (95% CI 0.62-1.10), 0.81 (95% CI 0.57-1.14) and 0.63 (95% CI 0.36-1.12). CONCLUSION These meta-analyses do not show clear survival advantage for TMT over dCRT. Only a non-significant trend towards better survival was seen, assuming comparable patient groups at baseline. Non-operative management of oesophageal carcinoma patients might be part of a personalised and tailored treatment approach in future. However, to date hard evidence proving its non-inferiority compared to operative management is lacking.

Abstract
OBJECTIVE Minimally invasive esophagectomy (MIE) has demonstrated superior outcomes compared to open approaches. The myriad of techniques has precluded the recommendation of a standard approach. The addition of robotics to esophageal resection has potential benefits. We sought to examine the outcomes with MIE to include robotics. METHODS Utilizing a prospective esophagectomy database, we identified patients who underwent (MIE) Ivor Lewis via thoracoscopic/laparoscopic (TL), transhiatal (TH), or robotic-assisted Ivor Lewis (RAIL). Patient demographics, tumor characteristics, and complications were analyzed via ANOVA, χ2, and Fisher exact where appropriate. RESULTS We identified 302 patients who underwent MIE: TL 95 (31.5%), TH 63 (20.8%), and RAIL 144 (47.7%) with a mean age of 65 ± 9.6. The length of operation was longer in the RAIL: TL (299 ± 87), TH (231 ± 65), RAIL (409 ± 104 min), p < 0.001. However, the EBL was lower in the patients undergoing transthoracic approaches (RAIL + TL): TL (189 ± 188 ml), TH (242 ± 380 ml), RAIL (155 ± 107 ml), p = 0.03. Conversion to open was also lower in these patients: TL 7 (7.4%), TH 8 (12.7%), RAIL 0, p < 0.001. The R0 resection rate and lymph node (LN) harvest also favored the RAIL cohort: TL 86 (93.5%), TH 60 (96.8%), and RAIL 144 (100%), p = 0.01; LN: TL 14 ± 7, TH 9 ± 6, and RAIL 20 ± 9, p < 0.001. The overall morbidity was lower in MIE patients that underwent a transthoracic approach vs. transhiatal: TL 29 (30.5%), TH 39 (61.9%), RAIL 34 (23.6%), p < 0.001. CONCLUSIONS Patients undergoing MIE via thoracoscopic/laparoscopic and robotic transthoracic approaches demonstrated lower EBL, morbidity, and conversion to open compared to the transhiatal approach. Additionally the oncologic outcomes measured by R0 resections and LN harvest also favored the patients who underwent a transthoracic approach.

Abstract
After curative treatment of esophageal squamous cell cancer (ESCC), patients are
at high risk for recurrence. The objective of this study was to develop an index
with a high sensitivity and specificity to predict ESCC patients’ recurrence and
prognosis. A retrospective analysis was conducted on consecutive patients with
EC who underwent esophagectomy. In total, 1417 patients were included in the
current investigation. In total, 770 patients were included in the current
study’s exploratory group. Alcohol consumption, TNM classification, number of
lymph node station metastases, and number of lymph node metastases were
significantly correlated with recurrence. Multivariate logistical regression
analysis resulted in the development of an equation for predicting recurrence
and prognosis (REEC). When using the REEC value to predict recurrence, the
cutoff value was 1.095, the area under the curve (AUC) values of the REEC were
0.68 (p < 0.001) in the Exploratory Group and 0.65
(p < 0.001) in the Validation Group, and the sensitivity
and specificity were 76.68% and 51.18%, respectively. When using the REEC value
to predict prognosis, the cutoff value was 1.215, the AUC values of the REEC
were 0.65 (p < 0.001) in the Exploratory Group and 0.64
(p < 0.001) in the Validation Group, and the sensitivity
and specificity were 73.12% and 50.67%, respectively. In the Exploratory Group,
when the REEC value was >1.095, patients had a longer median overall survival
(OS) and median disease-free survival (DFS) than those whose REEC value was <
1.095 (70.01±2.01 months versus 50.92±2.85 months and 75.66±1.35 months versus
53.68±2.81 months, respectively, p < 0.001). The differences
were confirmed to still exist in the Validation Group (48.12±1.47 vs 32.68±2.53
months and 55.61±1.32 vs 35.68±2.73 months respectively, p <
0.001).This study reported an index that can predict esophageal cancer
recurrence and prognosis, and its use can benefit patients.

Abstract
Background We examined the association between numbers of lymph nodes examined (LNEs) and accurate staging and survival to determine the optimal LNE count during esophagectomy using data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry and the Department of Thoracic Surgery of a single institution (SI). Methods A total of 7356 EC patients met our inclusion criteria from the SEER database and 1275 patients from SI. We applied multivariate models to investigate the relationship between the LNE count and LN metastasis and cancer‐specific survival (CSS). Odds ratios (ORs) and hazard ratios (HRs) generated by the multivariate models were fitted with Locally Weighted Scatterplot Smoothing, and the structural breakpoints were determined by the Chow test. Results Higher numbers of LNEs were linked to a higher proportion of LN metastasis and better CSS in both cohorts. Cut‐point analysis determined a threshold of LNEs of 12 for adenocarcinoma and 14 for esophageal squamous cell cancer (ESCC) considering accurate staging, and 15 for adenocarcinoma and 14 for ESCC considering OS. The cut‐points for CSS were examined in the SEER database and validated in the divided cohort from SI (all P < 0.05). Conclusion A greater number of LNEs are significantly associated with more accurate N staging and better survival in EC patients. We recommend 15 and 14 as the threshold LNE counts for adenocarcinoma and ESCC patients, respectively.

Abstract
Fast track is a standardised goal directed patient's care pathway that aims to facilitate recovery following surgery. Currently, there are large variations in the fast track protocols used in oesophagectomy due to the complexity of the procedure. The objective of this systematic review is to assess the evolution of fast track protocols following oesophagectomy since its implementation and the resulting effect on postoperative outcomes. Relevant electronic databases were searched for studies assessing the clinical outcome from fast track in oesophagectomy and also those assessing the effects of the individual key components in fast track protocols. The search yielded twenty-three publications regarding fast track implementation in oesophagectomy. A pattern of consistent evolution in fast-track protocols was clearly demonstrated and these have shown variations in the core-identified components across the studies. However, evolution in fast track protocols over time showed, an overall improvement in length of stay, anastomotic leak, pulmonary complications and mortality over time. Thirty publications were included that evaluated specific components of fast track protocols, with an increasing trend towards addressing the nutritional aspect in oesophagectomy care in more recent years. The variations in the key components of fast track protocol of care identify the need for continued assessment and identification for areas of improvement. In the future incremental gains through focused improvements in key components will lend itself to even better postoperative outcomes and patient experience during oesophageal cancer treatment.

Abstract
We have come a long way from the onset of surgery for esophageal cancer. Surgical resection is pivotal for the long-term survival in patients with locally advanced esophageal cancer. Moreover, advancements in post-operative care and surgical techniques have contributed to reductions in morbidity. More recently minimally invasive esophagectomy has been increasingly used in patients undergoing esophageal cancer resection. Potential advantages of MIE include: the decreased pulmonary complications, lower post-operative wound infection, decreased post-operative pain, and decreased length of hospitalization. The application of robotics to esophageal surgery is becoming more widespread. Robotic esophageal surgery has potential advantages over the known limitations of laparoscopic and thoracoscopic approaches to esophagectomy while adhering to the benefits of the minimally invasive approach. This paper is a review of the evolution from open esophagectomy to the most recent robotic approach.

Abstract
PURPOSE Thoracoabdominal esophageal resection for malignant disease is frequently associated with pulmonary infection. Whether prolonged antibiotic prophylaxis beyond a single perioperative dose is advantageous in preventing pulmonary infection after thoracoabdominal esophagectomy remains unclear. METHODS In this retrospective before-and-after analysis, 173 patients between January 2009 and December 2014 from a prospectively maintained database were included. We evaluated the effect of a 5-day postoperative course of moxifloxacin, which is a frequently used antimicrobial agent for pneumonia, on the incidence of pulmonary infection and mortality after thoracoabdominal esophagectomy. RESULTS 104 patients received only perioperative antimicrobial prophylaxis (control group) and 69 additionally received a 5-day postoperative antibiotic therapy with moxifloxacin (prolonged-course). 22 (12.7%) of all patients developed pneumonia within the first 30 days after surgery. No statistically significant differences were seen between the prolonged group and control group in terms of pneumonia after 7 (p = 0.169) or 30 days (p = 0.133), detected bacterial species (all p > 0.291) and 30-day mortality (5.8 vs 10.6%, p = 0.274). CONCLUSION A preemptive 5-day postoperative course of moxifloxacin does not reduce the incidence of pulmonary infection and does not improve mortality after thoracoabdominal esophagectomy.

Abstract
BACKGROUND Short- and long-term health-related quality of life (HRQL) was severely affected after surgery. This study aimed to assess the direction and duration of HRQL from 3- to 24-month follow-ups after minimally invasive esophagectomy (MIE) for esophageal cancer. METHODS A systematic literature search in MEDLINE, EMBASE, and the Cochrane database was performed for all potentially relevant studies published until February 2017. Studies were included if they addressed the question of HRQL with OERTC-QLQ-C30 and OES18. Primary outcomes were HRQL change at 3-month follow-up. Secondary outcomes were HRQL change from 3-, 6- (short-term) to 12- (mid-term), and/or 24-month (long-term) follow-ups. RESULTS Six articles were included to estimate the change in 24 HRQL outcomes after MIE. Most of the patients' HRQL outcomes deteriorated at short-term follow-up and some lasted to mid- or long-term after MIE. Patients' physical function and global QOL deteriorated from short- to long-term follow-ups, and emotional function had no change. The directions of dyspnea, pain, fatigue, insomnia, constipation, diarrhea, cough, and speech problems were increased. The deterioration in global function lasted 6 months, the increase in constipation and speech problems lasted 12 months, and insomnia increased more than 12 months after MIE. CONCLUSIONS The emotional function had no change after MIE. The global QOL become worse during early postoperative period; the symptoms of constipation, speech problems, and insomnia increased for a long time after MIE.

Several esophageal resection techniques have been reported in literature. The objective of this study is to assess postoperative and oncological outcomes of two-stage minimally invasive esophagectomy (MIE) in a prone position using thoracoscopic hand-sewn anastomosis. Consecutive patients who underwent two-stage MIE in 2016 performed by the senior author were included. This was compared with the preceding cohort of consecutive patients who underwent two-stage hybrid esophagectomy (HE). The primary outcome was 30-day morbidity and mortality. The secondary outcomes were operation duration, length of stay (LOS), total nodes examined (TNE), number of positive nodes (NPN), and resection margin. Overall, 15 patients underwent MIE and 11 patients underwent HE. Respiratory complications occurred in three (20.0%) patients in the MIE group and in five (45.5%) patients in the HE group (P = 0.218). Cardiac complications occurred in two (18.2%) patients, and two other patients (18.2%) experienced anastomotic leak in the HE group. Mean operative duration was 349 ± 41.6 min in MIE and 309 ± 47.8 min in HE (P = 0.040). Median LOS was 10 days (range: 7-70) in MIE and 13 days (range: 10-116) in HE (P = 0.045). Median TNE was 23 (range: 12-36) in MIE and 20 (range: 14-47) in HE (P = 0.775). Longitudinal margin was involved in one patient (9.1%) in HE and no longitudinal margin was involved in the MIE group. Circumferential resection margin was involved in seven patients (46.7%) in MIE and in four patients (36.4%) in HE (P = 0.391). Two-stage MIE using hand-sewn technique is safe and feasible without compromising surgical and oncological outcomes. A multicenter large trial is recommended to confirm these results.

Impact of Sarcopenia on Unplanned Readmission and Survival After Esophagectomy in Patients with Esophageal Cancer. Ann Surg Oncol 2017; 25:456-464. [PMID: 29214454 DOI: 10.1245/s10434-017-6294-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Indexed: 12/27/2022]
Abstract
BACKGROUND Although sarcopenia increases postoperative complications following esophagectomy, its effects on prognosis remain unclear. This study was performed to identify the effect of sarcopenia on 90-day unplanned readmission and overall survival (OS) after esophagectomy. METHODS Ninety-eight patients with esophageal cancer who underwent esophagectomy were enrolled in this study. Unplanned readmission was defined as any emergent hospitalization within 90 days after discharge. Sarcopenia, defined as low muscle mass plus low muscle strength and/or low physical performance according to the Asian consensus definition, was assessed prior to esophagectomy. Multivariate logistic regression analysis was performed to identify factors that contributed to 90-day unplanned readmission. OS was estimated using the Kaplan-Meier method, and a Cox proportional hazards model was used to assess the relationship between sarcopenia and OS. RESULTS Thirty-one patients (31.6%) were diagnosed with sarcopenia. The 90-day unplanned readmission rate was significantly higher in patients with sarcopenia than those without (42.9% vs. 16.4%, respectively; p = 0.01). Multivariable logistic regression analysis showed that sarcopenia was an independent predictor of 90-day unplanned readmission [odds ratio 3.71, 95% confidence interval (CI) 1.29-11.05; p = 0.02], and the log-rank test showed that sarcopenia was associated with OS (p = 0.01). Moreover, sarcopenia was a significant predictor of OS after adjustment for age, sex, and pathological stage (hazard ratio 2.35, 95% CI 1.21-4.54; p = 0.01). CONCLUSIONS Sarcopenia is a risk factor for 90-day unplanned readmission and OS following esophagectomy. Assessment of sarcopenia could help to identify patients at higher risk of a poor prognosis after esophagectomy.

Abstract
Esophagectomy is pivotal for the long-term survival in patients with early stage and advanced esophageal cancer, and improved perioperative care and advanced surgical techniques have contributed to reduced postoperative morbidity. However, despite these advances, esophagectomy continues to be associated with significant morbidity and mortality. Minimally invasive esophageal surgery (MIE) has been increasingly used in patients undergoing surgery for esophageal cancer. Potential advantages of MIE include the decreased postoperative pain; lower postoperative wound infection, decreased pulmonary complications, and decreased length of hospitalization. Robotic esophageal surgery has the ability to overcome some of the limitations of laparoscopic and thoracoscopic approaches to esophagectomy while maintaining the benefits of the minimally invasive approach. In this article, we will review the clinical efficacy and outcomes associated with robotic-assisted Ivor Lewis esophagectomy (RAIL).

Abstract
Background Previous studies have shown that minimally invasive esophagectomy (MIE) is safe and feasible. However, several of these studies had selection bias because they included more patients with early-stage cancer, and no study has compared the outcomes of locally advanced pathologic T3 (pT3) esophageal carcinoma between MIE and open surgery. Methods This retrospective analysis included 229 patients with stage pT3 esophageal squamous cell carcinoma (ESCC) who underwent esophagectomy from January 2013 to June 2015. The outcomes included operative outcomes, postoperative complications, recurrence, and mid-term survival. Results Sixty-six patients underwent MIE and 163 patients underwent open surgery. No significant difference was noted in blood loss or resection completeness (R0) between the two groups. The operative duration was longer in the MIE than open surgery group (266.5±52.5 vs. 218.1±47.4, P<0.01), and the number of lymph nodes dissected was higher in the MIE than open surgery group (15.2±5.3 vs. 12.9±7.3, P=0.01). There was no significant difference in the length of stay or 30-day mortality rate between the two groups, but the intensive care unit stay was shorter in the MIE group (3 vs. 4, P=0.01). No difference in complications or recurrence was noted between the two groups. The 2-year overall survival (OS) rate was 72.8% for MIE and 69.4% for open surgery, and the 2-year disease-free survival (DFS) rate was 69.4% for MIE and 57.2% for open surgery. Conclusions For patients with locally advanced stage pT3 ESCC, MIE has perioperative outcomes comparable to those of open surgery without compromising recurrence or survival.

Abstract
BACKGROUND Anastomotic leak (AL) following oesophagectomy carries a high mortality and morbidity. Early detection and intervention is required for a successful outcome. We have examined the role of a high postoperative serum lactate in predicting which patients are at risk of developing an anastomotic leak(AL). MATERIALS AND METHODS All patients who underwent transthoracic oesophagectomy over a 3-year period were identified from a prospectively collected database. Medical records were reviewed to identify the highest serum lactate recorded from blood gas analysis over each 24hr post-operative period. Patients who underwent transhiatal and left thoraco-abdominal oesophagectomies were excluded. Patients who developed a chyle leak were excluded. RESULTS Of a total of 136 oesophagectomies included for analysis, 18 developed an AL (13.2%). Of these patients, 10 underwent thoracoscopic oesophageal mobilization with cervical anastomosis and the rest an Ivor Lewis procedure. Predictive factors for AL included neoadjuvant chemotherapy (15/18 83.3% vs 55/118 46.6% p = 0.0046) and number of positive lymph nodes (mean 4.2 vs control mean 2.3 p = 0.045). Overall net fluid balance was comparable between the 2 groups, although AL patients received slightly more fluid on Day 3. High lactate levels on days 1-3 were associated with an AL. Using a Day 2 lactate of 1.7 mmol/L, the sensitivity of predicting AL was 72% and specificity 88%. The mean lag time using existing diagnostic modalities was 7.9 days. CONCLUSION A serum lactate of >1.7 mmol/l on day 2 should raise the possibility of a potential AL. Such patients should be selected for more intensive monitoring, optimization and selective gastroscopy.

Abstract
Purpose Signet ring cell carcinoma of the esophagus (SRCCE) is an uncommon tumor associated with significant morbidity and mortality. There is still no consensus regarding cut-off values for tumor size, age and optimal treatment for SRCCE. Thus, we elucidated the current survival outcomes of patients with SRCCE and analyzed factors associated with prognosis. Methods A retrospective cohort study based on the SEER (The Surveillance, Epidemiology, and End Results) program database was conducted. We identified 537 patients (461 men and 76 women) newly diagnosed with SRCCE between January 2004 and December 2014. A multivariate Cox proportional hazards model was utilized to measure the mortality-associated risk factors in patients with SRCCE after adjusting for various variables. Results The 1-, 2- and 5-year disease-specific mortalities (DSM) were 51.6%, 67.6%, and 78.4%, respectively, and the median survival time was 12.0 months. The factors correlated with mortality hazard were marital status (unmarried versus married, Hazard Ratio (HR) = 1.443), tumor size (≥ 5 cm versus < 5 cm, HR = 1.444), tumor grade (high grade versus low grade, HR = 3.001), condition of primary tumor (T4 versus T1, HR = 2.178), regional lymph node metastasis (N1 versus N0, HR = 1.739), further metastasis (M1 versus M0, HR = 1.951) and chemotherapy (receiving chemotherapy versus no chemotherapy, HR = 0.464). Conclusions The contemporary 5-year DSM was 78.4%. Being unmarried, having a tumor size ≥ 5 cm, a high tumor grade, a score of T4 for tumor invasion of adjacent organs, a score of N1 for regional lymph node metastasis, a score of M1 for distant metastasis and no chemotherapy were independent predictors of high DSM.

Abstract
BACKGROUND Esophagectomy remains the gold standard in the curative intent treatment of resectable esophageal cancer. However, this procedure is complex and associated with high risk of complications. In an effort to reduce the postoperative morbidity associated with open esophagectomy various minimally invasive techniques have been introduced and developed during the recent years. The aim of the current study was to present our 4.5-year experience of the gradual implementation of various minimally invasive esophagectomy (MIE) techniques in our tertiary referral center. METHODS From May 2012 a transitional period from conventional open esophagectomy to MIE was initiated. This period was preceded by fellowships and visits to expert centers abroad. Thereafter, a gradual implementation and refinement of the new techniques followed. Technique related data were collected prospectively. RESULTS Between January 1st 2011 and December 31st 2016 a total of 249 patients underwent an esophagectomy in our unit. Seventy-six cases were performed through a conventional open esophagectomy and 173 by some type of MIE. An increasing utilization of MIE over this time period was seen and finally reached 100% of treatment intentions, during the last 2 years. Ten cases (5.7%) where converted to open approach. A decrease in leak rate, operating time, peroperative bleeding and hospital stay as well as an increasing number of harvested lymph nodes was observed during the implementation period. CONCLUSIONS The transition from conventional open esophagectomy to MIE was successful at our center. The implementation was overall safe with good postoperative outcomes, although changes in results required technical modifications over time.

Abstract
OBJECTIVE To assess whether weekday of surgery influences long-term survival in esophageal cancer. BACKGROUND Increased 30-day mortality rates have been reported in patients undergoing elective surgery later compared with earlier in the week. METHODS This population-based cohort study included 98% of all esophageal cancer patients who underwent elective surgery in Sweden in 1987 to 2010, with follow-up until 2014. The association between weekday of surgery and 5-year all-cause and disease-specific mortality was analyzed using a multivariable Cox proportional hazards model, providing hazard ratios (HRs) with 95% confidence intervals (CIs), adjusted for age, comorbidity, tumor stage, histology, neoadjuvant therapy, and surgeon volume. RESULTS Among 1748 included patients, surgery conducted from Wednesday to Friday entailed 13% increased all-cause 5-year mortality compared with surgery conducted from Monday to Tuesday (HR = 1.13, 95% CI, 1.01-1.26). The corresponding association was strong for early tumor stages (0-I) (HR = 1.59, 95% CI, 1.17-2.16), moderate for intermediate tumor stage (II) (HR = 1.28, 95% CI, 1.07-1.53), and absent in advanced tumor stages (III-IV) (HR = 0.93, 95% CI, 0.79-1.09). The increase in 5-year mortality for each later weekday (discrete variable) was 7% for all tumor stages (HR = 1.07, 95% CI, 1.02-1.12), 24% for early tumor stages (HR = 1.24, 95% CI, 1.09-1.41), 13% for intermediate stage (HR = 1.13, 95% CI, 1.05-1.22), whereas no increase was found for advanced stages (HR = 0.98, 95% CI, 0.92-1.05). The disease-specific 5-year mortality was similar to the all-cause mortality. CONCLUSIONS The increased 5-year mortality of potentially curable esophageal cancer after surgery later in the week suggests that this surgery is better carried out earlier in the week.

Abstract
Background Locoregional failure is a major problem associated with chemoradiation treatment for squamous cell esophageal carcinoma. The aim of this study was to assess the feasibility, efficacy, and toxicity of preoperative radiation (dose > 50 Gy) with platinum‐based chemotherapy followed by esophagectomy in locally advanced squamous cell carcinoma. Methods Data of patients with cT2‐cT4 or node positive squamous cell carcinoma of the esophagus who received trimodality treatment between February 2006 and June 2015 were reviewed. Results Forty‐four patients were treated with intensity‐modulated radiation therapy, volumetric‐modulated arc therapy or three‐dimensional radiation therapy. The median radiation dose was 60 Gy. The average volume of the lungs receiving 10 Gy was 48.1%, 20 Gy was 24.5%, and the average mean lung dose was 14 Gy. After chemoradiation, R0 resection was achieved in 31 patients (71%). Patients who received >60 Gy had a higher pathologic complete remission rate than those in the lower dose group (59.1% vs. 36.4%). R0 resection and radiation dose >60 Gy were associated with better overall survival in Cox proportional hazards regression analysis. The median follow‐up duration was 22.4 months and median survival was 25.6 months. Two‐year overall, progression‐free survival and locoregional control rates were 55.9%, 28.6%, and 56%, respectively. The most common grade 3–4 toxicities were esophagitis (63.6%) and neutropenia (25%). Grade 3–4 postoperative morbidities included surgical wound infection (2.3%), acute renal failure (2.3%), and anastomosis stricture (2.3%). Conclusion Trimodality treatment with a high preoperative radiation dose and chemotherapy yielded a good pathologic complete response rate, and long‐term survival with low toxicities.

Abstract
The impact of body weight on outcomes after robotic-assisted esophageal surgery for cancer has not been studied. We examined the short-term operative outcomes in patients according to their body mass index following robotic-assisted Ivor-Lewis esophagectomy at a high-volume tertiary-care referral cancer center and evaluated the safety of robotic surgery in patients with an elevated body mass index. A retrospective review of all patients who underwent robotic-assisted Ivor-Lewis esophagectomy between April 2010 and June 2013 for pathologically confirmed distal esophageal cancer was conducted. Patient demographics, clinicopathologic data, and operative outcomes were collected. We stratified body mass index at admission for surgery according to World Health Organization criteria; normal range is defined as a body mass index range of 18.5-24.9 kg/m2. Overweight is defined as a body mass index range of 25.0-29.9 kg/m2 and obesity is defined as a body mass index of 30 kg/m2 and above. Statistics were calculated using Pearson's Chi-square and Pearson's correlation coefficient tests with a P-value of 0.05 or less for significance. One hundred and twenty-nine patients (103 men, 26 women) with median age of 67 (30-84) years were included. The majority of patients, 76% (N = 98) received neoadjuvant therapy. When stratified by body mass index, 28 (22%) were normal weight, 56 (43%) were overweight, and 45 (35%) were obese. All patients had R0 resection. Median operating room time was 407 (239-694) minutes. When stratified by body mass index, medians of operating room time across the normal weight, overweight and obese groups were 387 (254-660) minutes, 395 (310-645) minutes and 445 (239-694), respectively. Median estimated blood loss (EBL) was 150 (25-600) cc. When stratified by body mass index, medians of EBL across the normal weight, overweight and obese groups were 100 (50-500) cc, 150 (25-600) cc and 150 (25-600), respectively. Obesity significantly correlated with longer operating room time (P = 0.05) but without significant increased EBL (P = 0.348). Among the three body mass index groups there was no difference in postoperative complications including thrombotic events (pulmonary embolism and deep venous thrombosis) (P = 0.266), pneumonia (P = 0.189), anastomotic leak (P = 0.090), wound infection (P = 0.390), any cardiac events (P = 0.793) or 30 days mortality (P = 0.414). Our data study demonstrates that patients with esophageal cancer and an elevated body mass index undergoing robotic-assisted Ivor-Lewis esophagectomy have increased operative times but no significantly increased EBL during the procedure. Other potential morbidities did not differ with the robotic approach.
