RESUMO
BACKGROUND: Chemotherapy and chemoradiation have become essential adjuncts to improve the survival of patients with resectable esophageal squamous cell carcinoma (ESCC) in the perioperative period. Although preoperative treatment plus surgery is commonly used, controversy remains regarding the optimal treatment strategy for patients with locally advanced ESCC. METHODS: A retrospective review of clinical stage II and III ESCC patients who underwent esophagectomy at Henan Cancer Hospital between October 2014 and October 2017 was performed. The patients were divided into a neoadjuvant chemotherapy (NAC) group and an adjuvant chemotherapy (AC) group. Propensity score matching (PSM) was used to exclude confounders. Survival was estimated using KaplanâMeier analysis and compared by the log-rank test. The Cox proportional hazards regression model was used for both the univariate and multivariate analyses. RESULTS: A total of 684 patients were enrolled, including 365 (53.4%) patients in the NAC group. After PSM, 294 pairs of patients were left. NAC prolonged the OS (not reached versus 57.3 months, P = 0.002) and DFS (57.2 vs. 36.4 months, P = 0.010) and decreased the total rate of recurrence (50.1% vs. 59.2%, P = 0.025) and local recurrence (27.9% vs. 36.7%, P = 0.022) compared with AC. The multivariable analyses showed that NAC plus surgery modality was an independent predictor for improved OS (HR: 0.582, 95% CI: 0.467-0.786, P = 0.001). CONCLUSION: NAC plus surgery prolonged OS and DFS, and significantly decreased the total rate of recurrence compared with surgery plus AC in patients with clinical stage II and III ESCC.

This study aimed to investigate the survival impact of the number of lymph nodes dissection (LND) in patients receiving neoadjuvant chemotherapy (NCT) for esophageal squamous cell carcinoma (ESCC). We retrospectively analyzed the clinical pathological data and survival of 407 ESCC patients who underwent esophagectomy after NCT between January 2015 and December 2016. The relationship between the number of LNDs and 5-year overall survival (OS) or disease-free survival (DFS) was plotted by using restricted cubic spline analysis. A Cox proportional hazards regression model was used to identify prognostic factors of OS and DFS. We observed an obvious non-linear relationship between LND and the hazard ratios (HRs) for OS (P = 0.0015) and DFS (P < 0.001) of all the patients. In the multivariate analysis of OS and DFS, the number of LNDs (greater than 28 and less than 46) had a significant protective effect on survival (OS: HR: 0.61, 95% CI: 0.42-0.88, P = 0.007; DFS: HR: 0.50, 95% CI: 0.36-0.70, P < 0.001). For patients with nodal metastases, it was also an independent prognostic factor for OS (HR, 0.56, 95% CI, 0.35-0.90, P = 0.017) and DFS (HR, 0.42, 95% CI, 0.28-0.65, P < 0.001). Some degree of lymphadenectomy after NCT was beneficial in improving 5-year OS and DFS for ESCC patients with nodal metastases. For patients with nodal negativity, more extended lymphadenectomy did not improve patient survival.

Optimal treatment for resectable esophageal squamous cell carcinoma (ESCC) is controversial, especially in the context of potential benefit of combining PD-1 blockade with neoadjuvant therapy. This phase 2 study aimed to assess neoadjuvant camrelizumab plus chemotherapy in this population. Patients (clinical stage II-IVA) received two cycles of neoadjuvant chemoimmunotherapy (NIC) with camrelizumab (200 mg on day 1) plus nab-paclitaxel (260 mg/m2 in total on day 1 and day 8) and cisplatin (75 mg/m2 in total on days 1-3) of each 21-day cycle. Surgery was performed approximately 6 weeks after completion of NIC. Primary endpoint was complete pathologic response (CPR) rate in primary tumor. Secondary endpoints were objective response rate (ORR) per RECIST v1.1, 2-year progression-free survival (PFS) rate after surgery, PFS, overall survival (OS) and safety during NIC and perioperative period. Between 17 January 2020 and 8 December 2020, 56 patients were enrolled, and 51 received esophagectomy. Data cutoff date was 25 August 2021. The CPR rate was 35.3% (95% CI, 21.7%-48.9%). NIC had an ORR of 66.7% (95% CI, 40.0%-70.4%) and treatment-related adverse events (TRAEs) of low severity (grade 1-2, 75.0%; grade 3, 10.7%; grade 4-5, no). No perioperative mortality occurred. Three (5.9%) patients had tumor recurrence and one (2.0%) patient died. The 2-year PFS rate, median PFS and median OS had not been reached yet. Camrelizumab plus neoadjuvant chemotherapy in resectable ESCC demonstrates promising efficacy with acceptable toxicity, providing a feasible and effective option. Study is ongoing for long-term survival analyses.

Transhiatal esophagectomy facilitates esophageal resection without the need for thoracotomy. However, this procedure carries the risks of blind and blunt dissection within the mediastinum. More recently, video-assisted or mediastinoscopic transhiatal esophagectomy was introduced to mobilize the esophagus under direct visualization. Even though, the procedure is technically demanding and animal studies have shown that the CO2 pneumomediastinum may be associated with hemodynamic instability. By further developing already established techniques, we pioneered the transhiatal esophageal mobilization by using hybrid gastroscope (Fig. 1). Laparo-gastroscopic esophagectomy, which integrates gastroscope and laparoscope for esophageal mobilization, was successfully implemented on an esophageal cancer patient with a history of lung cancer surgery. The operative duration was 240 minutes with an estimated blood loss of 110âmL. The patient experienced an uneventful recovery and was discharged on postoperative day 9. Further studies will be required to confirm the surgical and oncological efficacy of this innovation.

OBJECTIVE: To determine whether RAL affects perioperative outcomes and long-term efficacy in NSCLC patients, compared with traditional VAL. SUMMARY OF BACKGROUND DATA: RAL is a promising treatment for NSCLC. However, its efficacy has not been fully evaluated. METHODS: A single-center, open-labeled prospective randomized clinical trial was launched in May 2017 to compare the efficacy of RAL and VAL. By May 2020, 320 patients were enrolled. The perioperative results of RAL and VAL were compared. RESULTS: The 320 enrolled patients were randomly assigned to the RAL group (n = 157) and the VAL group (n = 163). Perioperative outcomes were comparable between the 2 groups, including the length of hospital stay (P = 0.76) and the rate of postoperative complications (P = 0.45). No perioperative mortality occurred in either group. The total amount of chest tube drainage {830âmL [interquartile range (IQR), 550-1130 mL] vs 685âmL [IQR, 367.5-1160 mL], P = 0.007} and hospitalization costs [$12821 (IQR, $12145-$13924) vs $8009 (IQR, $7014-$9003), P < 0.001] were significantly higher in the RAL group. RAL group had a significantly higher number of LNs harvested [11 (IQR, 8-15) vs 10 (IQR, 8-13), P = 0.02], higher number of N1 LNs [6 (IQR, 4-8) vs 5 (IQR, 3-7), P = 0.005], and more LN stations examined [6 (IQR, 5-7) vs 5 (IQR, 4-6), P < 0.001]. CONCLUSIONS: Both RAL and VAL are safe and feasible for the treatment of NSCLC. RAL achieved similar perioperative outcomes, together with higher LN yield. Further follow-up investigations are required to evaluate the long-term efficacy of RAL. (ClinicalTrials.gov identifier: NCT03134534).

OBJECTIVES: Aspirations are common after esophagectomy. Data are lacking regarding its long-term radiological manifestations. The purpose of this study is to determine the incidence and radiological patterns of aspirations among long-term survivors and evaluate their clinical significance. METHODS: The records of all patients who underwent esophagectomy between October 2003 and December 2011 and survived more than 3 years were reviewed. Preoperative, first routine postoperative, and latest chest computed tomography (CT)scans were reviewed. Imaging studies were reviewed for radiological signs suspicious of aspirations, conduit location, anastomotic site, and maximal intrathoracic diameter. Data regarding patients' complaints during clinic visits were also collected. RESULTS: A total of 578 patients underwent esophagectomy during the study period. One-hundred twenty patients met the inclusion criteria. Median follow-up was 83.5 months. Cervical and intrathoracic anastomoses were performed in 103 and 17 patients, respectively. A higher rate of CT findings was found in postoperative imaging (n = 51 [42.5%] vs. n = 13 [10.8%] respectively, p < 0.05). Most of these were found in the lower lobes (61%). A higher rate of lesions was found among patients in whom the conduit was bulging to the right hemithorax compared with totally mediastinal or completely in the right hemithorax (54.5 vs. 35.2% and 34.6%, respectively, p < 0.05). No correlation was found with conduit diameter or anastomotic site. These lesions were more prevalent among patients who complained of reflux or cough during meals (NS). CONCLUSIONS: A significantly higher rate of new CT findings was found in postoperative imaging of this post-esophagectomy cohort, suggesting a high incidence of aspirations. The locations of the conduit, rather than anastomosis site, seem to play a role in the development of these findings. Further research is needed to evaluate the clinical significance of these findings.

The optimal perioperative fluid management during esophagectomy is still not clear. Liberal regimens have been associated with higher morbidity and respiratory complications. Restrictive regimens might raise concerns for kidney function and increase the need to associate vasopressors. The aim of this study was to investigate retrospectively the perioperative fluid administration during esophagectomy and to correlate this with postoperative respiratory outcome. All patients who underwent esophagectomy between January and December 2016 were retrospectively analyzed. Patient characteristics, type of surgery and postoperative course were reviewed. Fluid administration and vasopressor use were calculated intraoperatively and during the postoperative stay at the recovery unit. Fluid overload was defined as a positive fluid balance of more than 125 mL/m2/h during the first 24 hours. Patients were divided in 3 groups: GRP0 (no fluid overload/no vasopressors); GRP1 (no fluid overload/need for vasopressors); GRP2 (fluid overload with/without vasopressors). Postoperative complications were prospectively recorded according to Esophagectomy Complications Consensus Group criteria. A total of 103 patients were analyzed: 35 (34%) GRP0, 50 (49%) GRP1 and 18 (17%) GRP2. No significant differences were found for age, treatment (neoadjuvant vs. primary), type of surgery (open/minimally invasive), histology nor comorbidities. There were significant (P ≤ 0.001) differences in fluid balance/m2/h (75 ± 21 mL; 86 ± 22 mL and 144 ± 20 mL) across GRP0, GRP1 and GRP2, respectively. We found differences in respiratory complications (GRP0 (20%) versus GRP1 (42%; P = 0.034) and GRP0 (20%) versus GRP2 (61%; P = 0.002)) and "Comprehensive Complications Index" (GRP0 (20.5) versus GRP1 (34.6; P = 0.015) and GRP0 (20.5) versus GRP2 (35.1; P = 0.009)). Multivariable analysis (binary logistic regression) for "any respiratory complication" was performed. Patients who received fluid overload (GRP2) had a 10.24 times higher risk to develop postoperative respiratory complications. When patients received vasopressors alone (GRP1), the chances of developing these complications were 3.57 times higher compared to GRP0. Among patients undergoing esophagectomy, there is a wide variety in the administration of fluid during the first 24 hours. There was a higher incidence of respiratory complications when patients received higher amounts of fluid or when vasopressors were used. We believe that a personalized and protocolized fluid administration algorithm should be implemented and that individual risk factors should be identified.

The technique for bronchial stump suturing following lung resection which is currently applied in the Department of Thoracic Surgery at the University Hospitals Leuven, Belgium owes its name to the Dutch surgeon Dr. Klinkenbergh (1891-1985). A true pioneer of cardiothoracic surgery in Europe, Dr. Klinkenbergh dedicated himself to the surgical treatment of pulmonary tuberculosis. His work was praised by his peers for his precision and the reasoning behind every gesture. The Klinkenbergh technique consists in performing two running sutures which cross each other 'in the same manner as the laces of a shoe' to close the bronchus, limiting the occurrence of broncho-pleural fistulas. In our experience with more than 100 patients in the last 5 years (2016-2020) who underwent open pneumonectomy for benign or malignant disease, less than 2% developed post-operative broncho-pleural fistulas.

OBJECTIVE: Antireflux surgery can be proposed in patients with GORD, especially when proton pump inhibitor (PPI) use leads to incomplete symptom improvement. However, to date, international consensus guidelines on the clinical criteria and additional technical examinations used in patient selection for antireflux surgery are lacking. We aimed at generating key recommendations in the selection of patients for antireflux surgery. DESIGN: We included 35 international experts (gastroenterologists, surgeons and physiologists) in a Delphi process and developed 37 statements that were revised by the Consensus Group, to start the Delphi process. Three voting rounds followed where each statement was presented with the evidence summary. The panel indicated the degree of agreement for the statement. When 80% of the Consensus Group agreed (A+/A) with a statement, this was defined as consensus. All votes were mutually anonymous. RESULTS: Patients with heartburn with a satisfactory response to PPIs, patients with a hiatal hernia (HH), patients with oesophagitis Los Angeles (LA) grade B or higher and patients with Barrett's oesophagus are good candidates for antireflux surgery. An endoscopy prior to antireflux surgery is mandatory and a barium swallow should be performed in patients with suspicion of a HH or short oesophagus. Oesophageal manometry is mandatory to rule out major motility disorders. Finally, oesophageal pH (±impedance) monitoring of PPI is mandatory to select patients for antireflux surgery, if endoscopy is negative for unequivocal reflux oesophagitis. CONCLUSION: With the ICARUS guidelines, we generated key recommendations for selection of patients for antireflux surgery.

BACKGROUND: Neoadjuvant treatment followed by esophagectomy is standard practice in locally advanced esophageal cancer. However, not all patients who started neoadjuvant treatment will undergo esophageal resection. The purpose of our study was to investigate the group of patients, scheduled for neoadjuvant treatment followed by esophagectomy, who never made it to esophageal resection. METHODS: We retrospectively analyzed patients treated between 2002 and 2015 for locally advanced esophageal cancer, who did not undergo esophagectomy after neoadjuvant treatment. Subanalysis was performed according to time period (2002-2010 versus 2011-2015) and histology (adenocarcinoma versus squamous cell carcinoma). RESULTS: In 114 of 679 patients (16.8%), surgery was not performed after neoadjuvant treatment. Reasons for cancelation were disease progression (50 patients, 43.9%), poor general condition (26 patients, 22.8%), irresectability (14 patients, 12.3%), patients' own decision (15 patients, 13.2%), and death during neoadjuvant treatment (9 patients, 7.9%). In the second time period, there were less irresectable tumors (17.7% versus 5.8%; p = 0.044). Median overall survival was not different over time (9.2 versus 12.5 months; p = 0.937). Irresectability (p = 0.032), patients' refusal (p = 0.012), and poor general condition (p = 0.002) were more frequent as reasons for cancelation in squamous cell carcinoma patients. Median overall survival was, respectively, 12.5 and 9.9 months for adenocarcinoma and squamous cell carcinoma patients (p = 0.441). The majority of patients refusing surgery had a clinical complete response (73.3%). They had a median overall survival of 33.2 months. CONCLUSIONS: One in six patients starting neoadjuvant treatment for locally advanced esophageal cancer never made it to esophagectomy, more than half of them for oncological reasons, but also 1.3% because of death during treatment. Over time, irresectability as reason decreased. As a result, the relative weight of medical inoperability increased, indicating the importance of upfront testing of medical operability. Cancelation of surgery was significantly more common in patients with a squamous cell carcinoma, and this histology seems to represent a more complex oncological and functional entity. Refusal of esophagectomy based on clinical complete response showed a significant survival benefit compared to those who did not undergo esophagectomy because of other reasons.

OBJECTIVES: The current study aims to examine the impact of extracapsular lymph node involvement (EC-LNI) on survival for both esophageal adenocarcinoma (AC) and squamous cell carcinoma (SCC) treated with neoadjuvant chemoradiation therapy (nCRT) followed by surgery. BACKGROUND: Studies have demonstrated the negative prognostic value of EC-LNI in primary surgery, but its impact after nCRT remains unclear. METHODS: From the databases of 6 European high-volume centers 1505 patients with R0 resections were withheld. Oncologic variables, including ypT, ypN, number of positive lymph nodes, and lymph node capsular status: EC-LNI and intracapsular lymph node involvement (IC-LNI), were examined. Statistical analysis was performed by Cox proportional hazards modeling. RESULTS: In SCC 182 patients (31.6%) had positive lymph nodes, of whom 60 (33.0%) showed EC-LNI. In AC 391 patients (42.1%) had positive lymph nodes, of whom 147 (37.6%) showed EC-LNI. Overall 5-year survival (O5YS) in SCC was 42.0%. Presence of EC-LNI meant a significantly worse O5YS than IC-LNI or pN0 (10.6%, 39.5%, and 47.4%, respectively; P < 0.05). O5YS in AC was 41.2%. No significant difference was observed between EC-LNI and IC-LNI (P = 0.322). In the multivariate analysis, among the examined possible prognosticators, presence of EC-LNI showed the highest hazard ratio (2.29, confidence interval: 1.52-3.47) as an independent prognosticator for overall survival in SCC, but it was not in AC. CONCLUSIONS: Based on this international multicenter study, the presence of EC-LNI after nCRT is at least as important as N-stage for survival and EC-LNI is the strongest prognosticator for overall survival in SCC but not in AC.

OBJECTIVE: Our objective was to evaluate the impact of early oral feeding (EOF) on postoperative cardiac, respiratory, and gastrointestinal (CRG) complications after McKeown minimally invasive esophagectomy for esophageal cancer. SUMMARY BACKGROUND DATA: Nil-by-mouth with enteral tube feeding is routinely practiced after esophagectomy. METHODS: Patients were randomly allocated to receive oral feeding on the first postoperative day (EOF group) or late oral feeding (LOF group) 7 days after surgery. The primary endpoint was the occurrence of postoperative CRG complications, and the secondary outcomes included bowel function recovery and short-term quality of life (QOL). RESULTS: Between February 2014 and October 2015, 280 patients were enrolled in this study. There were 140 patients in the EOF group and 140 patients in the LOF group. EOF was noninferior to LOF for CRG complications (30.0% in the EOF group vs. 32.9% in the LOF group; 95% confidence interval of the difference: -13.8% to 8.0%). Compared with the LOF group, the EOF group showed significantly shorter time to first flatus (median of 2 days vs. 3 days, P = 0.001) and bowel movement (median of 3 vs. 4 days, P < 0.001). Two weeks after the operation, patients in the EOF group reported higher global QOL and function scores and lower symptom scores than patients in the LOF group. CONCLUSIONS: In patients after McKeown minimally invasive esophagectomy is noninferior to the standard of care with regard to postoperative CRG complications. In addition, patients in the EOF group had a quicker recovery of bowel function and improved short-term QOL.

BACKGROUND: Although endoscopic resection (ER) may be sufficient treatment for early-stage esophageal cancer, additional treatment is recommended when there is a high risk of cancer recurrence. It is unclear whether delaying esophagectomy by performing and assessing the success of ER affects outcomes as compared with immediate esophagectomy without ER. Additionally, long-term survival after sequential ER and esophagectomy required further investigation. METHODS: Between 2011 and 2015, 48 patients with stage T1 esophageal cancer underwent esophagectomy after ER with curative intent at our institution. Two-to-one propensity score methods were used to identify 96 matched-control patients who were treated with esophagectomy only using baseline patient, tumor characteristics and surgical approach. Time from initial evaluation to esophagectomy, relapse-free survival, overall survival, and postoperative complications were compared between the propensity-matched groups. RESULTS: In the ER + esophagectomy group, the time from initial evaluation to esophagectomy was significantly longer than in the esophagectomy only group (114 vs. 8 days, p < 0.001). The incidence of dense adhesion (p = 0.347), operative time (p = 0.867), postoperative surgical complications (p = 0.966), and postoperative length of hospital stay (p = 0.125) were not significantly different between the groups. Moreover, recurrence-free survival and overall survival were also similar between the two groups (p = 0.411 and p = 0.817, respectively). CONCLUSIONS: Treatment of stage T1 esophageal cancer with ER prior to esophagectomy did not increase the difficulty of performing esophagectomy or the incidence of postoperative complications and did not affect survival after esophagectomy. These results suggest that ER can be recommended for patients with stage T1 cancer even if esophagectomy is warranted eventually.

OBJECTIVE: Focal endoscopic resection (ER) followed by radiofrequency ablation (RFA) safely and effectively eradicates Barrett's oesophagus (BO) containing high-grade dysplasia (HGD) and/or early cancer (EC) in smaller studies with limited follow-up. Herein, we report long-term outcomes of combined ER and RFA for BO (HGD and/or EC) from a single-arm multicentre interventional study. DESIGN: In 13 European centres, patients with BO ≤ 12 cm with HGD and/or EC on 2 separate endoscopies were eligible for inclusion. Visible lesions (<2 cm length; <50% circumference) were removed with ER, followed by serial RFA every 3 months (max 5 sessions). Follow-up endoscopy was scheduled at 6 months after the first negative post-treatment endoscopic control and annually thereafter. OUTCOMES: complete eradication of neoplasia (CE-neo) and intestinal metaplasia (CE-IM); durability of CE-neo and CE-IM (once achieved) during follow-up. Biopsy and resection specimens underwent centralised pathology review. RESULTS: 132 patients with median BO length C3M6 were included. After entry-ER in 119 patients (90%) and a median of 3 RFA (IQR 3-4) treatments, CE-neo was achieved in 121/132 (92%) and CE-IM in 115/132 patients (87%), per intention-to-treat analysis. Per-protocol analysis, CE-neo and CE-IM were achieved in 98% and 93%, respectively. After a median of 27 months following the first negative post-treatment endoscopic control, neoplasia and IM recurred in 4% and 8%, respectively. Mild-to-moderate adverse events occurred in 25 patients (19%); all managed conservatively or endoscopically. CONCLUSIONS: In patients with early Barrett's neoplasia, intensive multimodality endotherapy consisting of ER combined with RFA is safe and highly effective, and the treatment effect appears to be durable during mid-term follow-up.

OBJECTIVES: At present there is controversy regarding the optimal surgical method for esophageal cancer. Specifically, whether combined thoracoscopic-laparoscopic esophagectomy is superior to open esophagectomy with respect to the surgical wound, perioperative morbidities and mortality, and the overall survival rate is of great concern. This article aimed to compare thoracoscopic-laparoscopic esophagectomy versus open esophagectomy on the perioperative morbidities and long-term survival. METHODS: PubMed, Embase, and Google Scholar databases were searched for relevant studies comparing combined thoracoscopic-laparoscopic esophagectomy with open esophagectomy using the Preferred Reporting Items for Systemic Reviews and Meta-Analyses standards. Odds ratios were extracted to give pooled estimates of the perioperative effect of the two surgical procedures. Hazard ratios were extracted to compare overall survival between the two surgical procedures. RESULTS: Thirteen studies involving 1549 patients were included in this meta-analysis. We found that patients that underwent combined thoracoscopic-laparoscopic esophagectomy had lower total complication rates (relative risk 1.20; 95 % CI 1.08-1.34; p = 0.0009), wound infection rates, pulmonary complications, and less intraoperative blood loss. Moreover, our study also showed combined thoracoscopic-laparoscopic esophagectomy did not compromise the 5-year survival rate (hazard risk 0.920; 95 % CI 0.720-1.176; p = 0.505) and even improved 2-year survival rate. The 30-day mortality and other common morbidities, including anastomotic leakage, anastomotic stricture, pulmonary infection, chylothorax, arrhythmia, or recurrent laryngeal nerve injury, were not significantly different between combined thoracoscopic-laparoscopic esophagectomy and traditional open esophagectomy (p > 0.05). CONCLUSIONS: Combined thoracoscopic-laparoscopic esophagectomy is a feasible and reliable surgical procedure that can achieve uncompromising long-term survival rates and reduce perioperative complications.

INTRODUCTION: Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. METHODS: The Esophageal Complications Consensus Group comprised 21 high-volume esophageal surgeons from 14 countries, supported by all the major thoracic and upper gastrointestinal professional societies. Delphi surveys and group meetings were used to achieve a consensus on standardized methods for defining complications and quality measures that could be collected in institutional databases and national audits. RESULTS: A standardized list of complications was created to provide a template for recording individual complications associated with esophagectomy. Where possible, these were linked to preexisting international definitions. A Delphi survey facilitated production of specific definitions for anastomotic leak, conduit necrosis, chyle leak, and recurrent nerve palsy. An additional Delphi survey documented consensus regarding critical quality parameters recommended for routine inclusion in databases. These quality parameters were documentation on mortality, comorbidities, completeness of data collection, blood transfusion, grading of complication severity, changes in level of care, discharge location, and readmission rates. CONCLUSIONS: The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects.

OBJECTIVE: To clarify the biologic behavior of esophageal signet ring cell (SRC) carcinomas of the esophagus and gastroesophageal junction (GEJ). To evaluate the accuracy of pretreatment biopsies in diagnosing true SRC carcinoma. BACKGROUND: In contrast with gastric cancer, little is known about the biologic behavior and prognosis of SRC. METHODS: All adenocarcinomas (ADC) of the esophagus and GEJ-patients undergoing primary resection between 1990 and 2009 were included (n = 920). Specimens containing SRCs (n = 114) were classified according to World Health Organization criteria (>50% SRC or <50% SRC). RESULTS: Thirty-two patients showed more than 50% SRC and 71 patients showed less than 50% SRC. Overall cancer-specific 5-year survival was worse for SRC (22.4%, P < 0.0001) and for SRC > 50% (13.6%, P = 0.0001) compared with ADC. Complete resection was achieved in 86.5% of patients (n = 697) in ADC, 69.5% (n = 57) in SRC < 50%, and 78.1% (n = 25) in SRC > 50% (vs ADC, respectively, P < 0.0001 and P = 0.1801). In 379 pN + R0 patients, the median number of positive lymph nodes was comparable between ADC and SRC < 50% (4 vs 5, P = 0.207) or SRC > 50% (4 vs 8, P = 0.077). Compared with ADC, SRC > 50% showed more pN3's (30% vs 61%, P = 0.006), higher recurrence (56% vs 42% for ADC, P = 0.003), and local-regional recurrences (29% vs 16%, P = 0.002). Pretreatment biopsies were unreliable to define the presence of SRC > 50% (sensitivity = 56.3%, positive predictive value = 43.9%). CONCLUSIONS: SRCs are aggressive neoplasms associated with poorer prognosis than other ADCs after primary esophagectomy. Because our data suggest that pretreatment biopsies failed to reliably define presence of SRC > 50%, presence of SRCs in pretreatment biopsies seems to be of no use to define treatment strategy or prognosis.

Background: While the widespread use of endoscopic submucosal dissection (ESD) has significantly reduced the incidence of early esophageal cancer (ESCA), the limited ability of ESD to strip deep infiltrating esophageal lesions results in a considerable risk of intraoperative perforation. Circulating-free DNA (cfDNA) is widely used in modern tumor screening due to its non-invasive detection capabilities. A methylation analysis offers vital insights into the condition and advancement of malignancies due to its unique positioning, such as a marker of cancer. This study investigated the potential of combining a non-invasive liquid biopsy technique, along with a methylation analysis, to assess the surgical perforation risk of ESCA patients. Methods: In this study, we conducted an analysis of gene expression differences between stage I esophageal squamous carcinoma samples and healthy tissue samples using data from The Cancer Genome Atlas (TCGA) database. We also identified the genes associated with progression-free survival (PFS) in esophageal squamous carcinoma. Integrating the framework of the methylation analysis, we explored the methylated sites of these distinct genes. To refine this process, we used the Shiny Methylation Analysis Resource Tool (SMART) to conduct a comprehensive analysis of these sites. We then confirmed the stability of the methylation sites in different lesion conditions using methylation-specific quantitative polymerase chain reaction (MS-qPCR) with paraffin tissue samples collected after ESD. Results: We analyzed RNA-sequencing data from 42 early stage ESCA patients and 17 controls, identifying 1,263 up-regulated and 460 down-regulated genes. Functional analyses revealed involvement in key pathways such as cell cycle regulation and immune responses. Furthermore, we identified 38 differentially expressed genes associated with PFS. Using SMART analysis, we found 217 hyper-methylated regions in 38 genes, suggesting potential early markers for ESCA. Validation experiments confirmed the reliability of 29 hyper-methylated regions in FFPE tissue samples and 6 regions in cfDNA. A LunaCAM model showed high accuracy [area under the curve (AUC) =0.89] in discriminating early ESCA. Integrated assessment of six highly methylated regions significantly improved predictive performance, with 90.56% sensitivity, highlighting the importance of combinatorial biomarker evaluation for early cancer detection. Conclusions: This study established a novel approach that integrates non-invasive testing with a methylation analysis to assess the surgical risk of early ESCA patients. The significance of changes in methylation sites in relation to lesion status should not be underestimated, as they have the potential to offer vital insights for proactive risk assessments before surgery.
