Abstract Background To compared the patterns of lymph node recurrence after different prophylactic therapies to identify specific and effective target areas for prophylactic radiotherapy. Methods This retrospective study enrolled patients with recurrence from August 2011 to November 2015, who underwent different prophylactic therapies for esophageal squamous cell carcinoma after radical surgery previously. The patients were divided into unprotected, radiotherapy, chemotherapy, and radiochemotherapy groups. The recurrence patterns between these groups were compared. Results A total of 186 patients who met the above criteria were enrolled. The recurrence ratios of regional lymph nodes were 84.2%, 31.3%, 84.0%, and 48.0% in the unprotected, radiotherapy, chemotherapy, and radiochemotherapy groups, respectively. The recurrence ratio of regional lymph nodes in patients who received radiotherapy was significantly decreased ( P =0.009). The recurrence ratio of superior mediastinal lymph node was significantly lower than those of the chemotherapy and unprotected groups ( P =0.000). The recurrence ratios of the radiotherapy group with and without epigastrium coverage were 4/16 and 4/25, respectively, indicating no statistical difference with those of other groups ( P =0.259). The recurrence ratios with and without the coverage of anastomotic sites were 2/19 and 3/22, respectively, revealing no statistical difference with those of other groups ( P =0.712). Conclusion Prophylactic radiotherapy can significantly reduce the recurrence of regional lymph nodes, especially lymph node recurrence on the superior mediastinum.

BackgroundThe lower neck and upper mediastinum are the major regions for postoperative radiotherapy (PORT) in thoracic esophageal squamous cell carcinoma (TESCC). However, there is no uniform standard regarding the delineation of nodal clinical target volume (CTVnd). This study aimed to map the recurrent lymph nodes in the cervical and upper mediastinal regions and explore a reasonable CTVnd for PORT in TESCC.MethodsWe retrospectively reviewed patients in our hospital with first cervical and/or upper mediastinal lymph node recurrence (LNR) after upfront esophagectomy. All of these recurrent lymph nodes were plotted on template computed tomography (CT) images with reference to surrounding structures. The recurrence frequency at different stations was investigated and the anatomic distribution of recurrent lymph nodes was analyzed.ResultsA total of 119 patients with 215 recurrent lymph nodes were identified. There were 47 (39.5%) patients with cervical LNR and 102 (85.7%) patients with upper mediastinal LNR. The high-risk regions were station 101L/R, station 104L/R, station 106recL/R, station 105 and station 106pre for upper TESCC and station 104L/R, station 106recL/R, station 105, station 106pre and station 106tbL for middle and lower TESCCs. LNR in the external group of station 104L/R was not common, and LNR was not found in the narrow spaces where the trachea was in close contact with the innominate artery, aortic arch and mediastinal pleura. LNR below the level of the cephalic margin of the superior vena cava was also not common for upper TESCC.ConclusionsThe CTVnd of PORT in the cervical and upper mediastinal regions should cover station 101L/R, station 104L/R, station 106recL/R, station 105 and station 106pre for upper TESCC and station 104L/R, station 106recL/R, station 105, station 106pre and station 106tbL for middle and lower TESCCs. Based on our results, we proposed a useful atlas for guiding the delineation of CTVnd in TESCC.

Abstract Background Due to the difficulty of dissection, surgical trauma, postoperative complications and other factors, the promotion of 3-field lymph node dissection is subject to certain restrictions. We try to explore and summarize a method of lymph node dissection, ‘endoscopic 2.5 lymph node dissection ’, that is, thoracoscopy combined with laparoscopic radical abdominal field, chest field and lower cervical paraesophageal lymph nodes (including 101 group below thyroid artery). Methods Retrospective analysis of 240 patients with thoracic esophageal squamous cell carcinoma from November 1, 2015 to December 31, 2017. All patients underwent endoscopic 2.5-field lymphadenectomy. The average age is (58.2 ± 9.5) years old. During the thoracoscopic part, when we do the lymphadenectomy along recurrent laryngeal nerves in the upper mediastimun and lower neck, we used a combination of ‘esophageal suspension method’, ‘lymph node rolling dissection method’ and ‘multi-angle pulling method’ to reveal the lymph nodes (Figure 1). Surgical related factors were collected and analyzed. Continuous follow-up was performed to record the recurrence and metastasis of patients and postoperative survival. Results Lymphadenectomy level of the right recurrent laryngeal nerve could reach the level above the right inferior thyroid artery, and the left could reach the level of 101 station. All operations were successfully completed. The incidence of pulmonary infection was 11.7%, the incidence of anastomotic leakage was 1.3%, the hoarseness rate was 7.9% and the incidence of chylothorax was 4.2%. The average number of total, abdominal and thoracic lymph nodes dissected were higher than the number of guidelines requirement and most of the previous literature. The average postoperative hospital stay was 8.4 days. The local recurrence rate, metastasis rate and survival rate of all the patients were not inferior to those reported in the past. Conclusion In patients with thoracic esophageal squamous cell carcinoma, the use of ‘total endoscopic 2.5-field lymph noede dissection’, could expand the range of lymph node dissection, and reached the super-thoracic and lower cervical level, which is beneficial to improve the degree of dissection along the recurrent laryngeal nerves. The procedure is safe and feasible, the results of short-term follow-up results are good, and it is worth further promotion. Disclosure All authors have declared no conflicts of interest.

Background: We aim to assess the prognostic ability of three common lymph node–based staging algorithms, namely, the number of positive lymph nodes (pN), the lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in patients with esophageal squamous cell carcinoma (ESCC). Methods: A total of 3902 ESCC patients treated at 10 Chinese institutions between 2003 and 2013 were included, along with 2465 patients from the Surveillance, Epidemiology, and End Results (SEER) database. The prognostic ability of the aforementioned algorithms was evaluated using time-dependent receiver operating characteristic (tdROC) curves, R2, Harrell’s concordance index (C-index), and the likelihood ratio chi-square score. The primary outcomes included cancer-specific survival (CSS), overall survival (OS), and CSS with a competing risk of death by non-ESCC causes. Results: LODDS had better prognostic performance than pN or LNR in both continuous and stratified patterns. In the multicenter cohort, the multivariate analysis showed that the model based on LODDS classification was superior to the others in predictive accuracy and discriminatory capacity. Two nomograms integrating LODDS classification and other clinicopathological risk factors associated with OS as well as cancer-specific mortality were constructed and validated in the SEER database. Finally, a novel TNLODDS classification which incorporates the LODDS classification was built and categorized patients in to three new stages. Conclusion: Among the three lymph node–based staging algorithms, LODDS demonstrated the highest discriminative capacity and prognostic accuracy for ESCC patients. The nomograms and novel TNLODDS classification based on LODDS classification could serve as precise evaluation tools to assist clinicians in estimating the survival time of individual patients and improving clinical outcomes postoperatively in the future.

BackgroundLymph node metastasis is a primary contributor to tumor progression in esophageal squamous cell carcinoma (ESCC), and the optimal extent of lymphadenectomy during esophagectomy remains controversial. This study aimed to investigate the appropriate number of lymph nodes to be dissected in pT1-2Nany stage ESCC to achieve the best prognosis and avoid missing positive lymph nodes (PLNs).MethodsA total of 497 patients with pT1 to pT2 esophageal cancer from two institutions were retrospectively analyzed and their surgical and pathological records were critically reviewed. Stepwise analyses were conducted by calculating a serial of hazard ratios and odd ratios to determine the optimal range of lymphadenectomy for overall survival (OS).ResultsThe best survival outcome can be obtained when the number of lymph node examined (NLNE) is 10–18 in pT1N0 ESCC, while the NLNE should exceed 24 in pT2N0 diseases. In patients with pT1-2Nany and pT2Nany ESCC, resection of 15–25 and 24–37 lymph nodes, respectively, could provide significant added value for identifying positive nodal metastasis. When the NLNE exceeds this appropriate range, resection of extra lymph node is not helpful to improve the probability of finding PLNs.ConclusionsFor ESCC patients undergoing radical esophagectomy, the optimal extent of lymphadenectomy is 15–25 for pT1Nany disease and 24–37 for pT2Nany disease.

Abstract Background The possible presence of occult tumor dissemination is the rationale of radical systematic lymphadenectomy. Theoretically, the more extent of lymphadenectomy, the more similar survival outcomes between node-negative and node-positive patients. Accordingly, there will be a certain number of examined lymph nodes (NELN) for patients with only one tumor-positive lymph node that can equal their survival with the node-negative patients, and this cut-off point should be define the minimal requirement for an adequate extent of lymphadenectomy. The aim of this report was to determine the optimal number of examined lymph nodes (NELN) dissection for esophageal squamous cell carcinoma (ESCC) by this novel method. Methods We retrospectively reviewed 589 ESCC patients from June 2011 and July 2012. Among them, 372 patients were pathologically confirmed with node-negative (N 0 + ), and 217 patients with only one tumor-positive lymph node (N 1 + ). Comparison of overall survival were performed using the Kaplan-Meier method. Cox regression hazard model was used for multivariate analysis to assess the independent influence of NELN on overall survival. Results The median survival for N 0 + and N 1 + patients was 32 versus 23 months (HR 1.61; 95% CI 22.86- 29.148; P = 0.000). Survival analyses revealed that the NELN positively correlated with overall survival (OS) both for patients with N 0- (P = 0.024) and N 1 + (P = 0.046), and an independent prognostic predictor only for N 0 + patients (hazard ratio 0.984; P = 0.032). When the cut-off point of NELN was set as a value less than 18, stratum analysis within the Kaplan–Meier method showed that NELN did not affect the results that N 1 + patients have a worse overall survival as compared with N 0 + patients (P < 0.05). However, stratum analysis showed that no significant difference in OS was observed between N 1 + and N 0 + patients when the NELN was greater than 18. Conclusion The NELN should be considered a mandatory requirement for improving the OS of ESCC patients. The minimum of 18 lymph nodes removed for ESCC is rational and should be complied with.

Abstract Background Early radical resections are the main treatment methods towards esophageal squamous cell carcinoma (ESCC). Classic transthoracic esophagectomy (McKeown approach) could resect esophagus lesion as a whole piece, so the surgical results could be satisfactory and the regional lymph node dissection could be clean. With the maturation of video-assisted thoracoscope in thoracic surgeries, good vision, subtle operating system, and mature operating technologies have made the multi-portal thoracoscopic minimally invasive laparoscopic esophageal resection more and more mature. Meanwhile, SPVATS gradually appeared, which was firstly used in simple thoracic surgeries, and further applied to lung and mediastinal tumor resection; relevant summaries have been reported, and the feasibility of SPVATS for standard mediastinal lymph node dissection was also further verified.The application of SPVATS towards TESCC has also been gradually carried out. Would minimally invasive esophagectomy be safe? Whether SPVATS could be used in the McKeown approach for TESCC? Whether SPVATS could safely resect esophagus, and perform standard dissection towards local esophageal region and mediastinal lymph nodes, as well as avoid damaging the surrounding organs and tissues? Some scholars had compared SPVATS and multi-portal VATS in treating medio-inferior TESCC. Methods METHODS: 25 McKeown approach-based SPVATS surgeries (19 males and 6 females, aged 42–70years) were carried out from January 2015 to December 2017 to treat TESCC, including 2 case in upper thoracic segment, 15 cases in median thoracic segment, and 8 cases in inferior thoracic segment. All the cases were pathologically diagnosed as SCC preoperatively. SPVATS was performed to free thoracic esophagus and dissect the lymph nodes, and laparoscopy was performed to free stomach and to perform esophagus-left gastric collum anastomosis. Results RESULTS: All the patients were successfully completed SPVATS, with average thoracic surgery time as 150 min, intraoperative blood loss as 30–260 ml (average 90 ml), and postoperative hospital stay as 9–16d (average 12d). Conclusion CONCLUSIONS: SPVATS was technically feasible and safe in treating TESCC using McKeown approach, with less trauma and rapid postoperative recovery, so it could be used as a new surgical option for McKeown approach-based TESCC treatment.
