Abstract Aim To evaluate the involvement of subcarinal lymph node dissection (SLND) in the surgical treatment of esophageal cancer, as well as its impact on surgical outcomes following esophagectomy. Background & Methods Data on patients that underwent esophagectomy from 01/03/2014 to 01/03/2019 were prospectively collected and retrospectively reviewed. Based on the medical records, the following parameters were collected and analyzed: patient demographics, histopathological parameters, surgical- oncological outcomes. All patients were staged according to the AJCC 8th edition. Results A total of 79 patients underwent Ivor Lewis or McKeown esophagectomy for either squamous cell carcinoma (n= 7 patients) or adenocarcinoma of the esophagus or gastroesophageal junction (n= 72 patients). In 26 cases, esophagectomy was performed without SLND, while 53 cases underwent SLND. Among the 53 patients, 50 (94.3%) were men, and 3 (5.7 %) were women. Mean age was 61.4 years, (range 34-78). Mean nodal harvest was 34.7 lymph nodes per patient. Lymph node invasion was noted in 33 patients (62.2%), with a mean of 9 positive lymph nodes per patient. Subcarinal lymph nodes were involved in 5 out of 53 patients (9.4%). The ratio of positive subcarinal lymph nodes to resected ones was 1/2 (50%), 3/3 (100%), 1/2 (50%), 1/2 (50%) and 1/1 (100%) for each patient. Final histopathological report showed adenocarcinoma of moderate or poor differentiation (G2 2/5, G3 3/5) in all five patients (100%). Four out of 5 patients had not received neoadjuvant treatment and their pathological staging was T3N3M0. One patient had received neoadjuvant chemotherapy and his final staging was ypT3N2M0. Noteworthy, the seven patients diagnosed with squamous carcinoma, were subjected to SLND and were 100% negative for invasion histologically. Conclusion Subcarinal lymph nodes were infiltrated in 9.4% of patients operated for esophageal cancer. In the squamous cell cancer group, the relative infiltration rate was notably 0%. It seems that omission of subcarinal lymph node dissection during transthoracic esophagectomy cannot be justified.

Abstract Background The aim of the present study was to evaluate subcarinal lymph node dissection in transmediastinal radical esophagectomy and subcarinal lymph node metastasis in patients with esophageal cancer. Methods Three hundred and twenty-three patients with primary esophageal cancer who underwent transmediastinal or transthoracic esophagectomy with radical two- or three-field lymph node dissection were retrospectively investigated. The clinicopathological characteristics of patients with subcarinal lymph node metastasis were analyzed in detail. Results The median of dissected subcarinal lymph nodes in transmediastinal and transthoracic esophagectomy groups was 6 and 7, respectively, and there was no significant difference between the two groups (p = 0.12). Of all patients, 26 (8.0%) were pathologically diagnosed as positive for subcarinal lymph node metastasis, whereas only 7 (26.9%) of those with metastasis were preoperatively diagnosed as positive. In addition, all patients with subcarinal lymph node metastasis had other non-subcarinal lymph node metastasis. By univariate analysis, subcarinal lymph node metastasis was found in larger (≥ 30 mm) and deeper (T3/T4a) primary lesions (p = 0.02 and 0.02, respectively), but it was not found in 49 patients with the primary lesion located in the upper thoracic esophagus. Conclusions Subcarinal lymph nodes can be dissected in transmediastinal esophagectomy, almost equivalent to transthoracic esophagectomy. The tumor size, depth, and location may be predictive factors for subcarinal lymph node metastasis.

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.

Subcarinal Lymph Node

Abstract Background The subcarinal lymph node metastasis, although with the debate whether it is a characteristic of lung cancer or esophageal cancer, is prevalent in esophageal carcinoma, and with the incidence of 4.1%-17.5% according to some estimates. The aim of this study is to assess the pattern of subcarinal lymph node metastasis and the dissection strategy for thoracic esophageal carcinoma. Methods A large cohort, retrospective study was conducted on 596 patients with thoracic esophageal carcinoma treated from July 2008 to December 2010. The metastasis rate of subcarinal lymph node was investigated. Survival of patients treated by different dissection strategies was compared. The effectiveness index was used to assess the outcome of subcarinal lymph node dissection. Results Of 596 patients, 447 had documented subcarinal lymph node dissection (75.0%). According to whether the subcarinal lymph node was harvested or not, they were divided into two groups: dissection group (n = 447) and non-dissection group (n = 149). Their 5-year survival rates were 48.3 ± 1.7 months for dissection group vs. 38.1 ± 2.8 months for non-dissection group (P < 0.001). The overall subcarinal node metastasis rate in the dissection group was 12.5% (56/447). Based on the status of subcarinal nodes, there was a significant difference in survival, 52.3 ± 1.8 months with negative nodes (n = 391) compared to 19.9 ± 2.2 months for those with positive nodes (n = 56) (P < 0.001). Subgroup analysis was further conducted for the positive subcarinal nodes patients. The metastasis rates in patients with upper, middle and lower esophageal cancer were 5.4%, 15.1% and 10.1%, respectively (P < 0.05 for comparison between patients with upper and other segments). The effectiveness indices for these three groups of patients were as 0%, 4.8% and 27.2%, respectively. The metastasis rates for T0, T1, T2, T3 and T4 esophageal carcinoma were 0%, 0%, 3.5%, 10.7% and 19.0%, respectively (P < 0.05 for comparison between T0/T1/T2 and T3/T4 tumors. Conclusion Thoracic esophageal carcinoma has a high incidence of subcarinal lymph node metastasis, especially among those with middle and lower esophageal cancer, and for deeper invaded tumors. Therefore, for middle and lower esophageal tumors, subcarinal lymph node dissection is necessary, whereas for T1/2 upper esophageal tumors, subcarinal lymph node dissection can be spared from subcarinal lymph node dissection.
