ABSTRACT
Recurrent laryngeal nerve lymph node (RLN LN) is not only the most common site of esophageal squamous cell carcinoma metastasis, but also a key factor affecting the prognosis of patients. RLN LN is a reliable predictor of cervical lymph node metastasis, and its status determines whether cervical lymph node dissection should be performed. However, because of its wide range of operations, large trauma and high incidence of postoperative complications, it is very important to screen out the beneficiaries.
ABSTRACT
@#Objective To investigate the predictive value of recurrent laryngeal nerve lymph nodes (RLN) status for supraclavicular lymph node (SLN) metastasis in esophageal squamous cell carcinoma. Methods We retrospectively analyzed the clinical data of 83 patients with esophageal squamous cell carcinoma who underwent McKeown three-field lymphadenectomy from January 2017 to April 2018 in our hospital, including 53 males and 30 females with an average age of 64.07±7.05 years. Results The SLN metastasis rate of the patients was 24.1%. The rate in the thoracic and abdominal metastases positive (N1-3) group and negative (N0) group was 37.8% and 13.0%, respectively, with a statistical difference (P<0.05). The rate of SLN metastasis was significantly different between the RLN metastasis positive (RLN+) and negative (RLN–) groups (39.1% vs. 18.3%, P<0.05). One side of RLN metastasis could lead to SLN metastasis on the opposite side. No correlation between the SLN metastasis and age, gender, location, differentiation degree, maximum tumor diameter, T-staging or histologic type was observed (P>0.05). Multivariate analysis showed that lymph node metastasis in chest or abdomen was an independent predictor of SLN metastasis. Conclusion RLN+ is not the independent predictor for SLN metastasis. SLN should be dissected in N1-3 patients with esophageal squamous cell carcinoma without considering tumor location and T-staging. Bilateral SLN dissection should be recommended even if RLN metastasis is only unilateral.
ABSTRACT
Aim: Esophageal cancer remains a major and lethal health problem. In Nepal, not much has been explored about its management. The aim of this study was to conduct a retrospective review of esophageal cancer patients undergoing surgery or combined modality treatment at a cancer hospital in Nepal. Materials and Methods: Resectable cases were treated primarily with surgery. Locally advanced cases with doubtful or obviously unresectability underwent preoperative chemo/radiation or chemoradiation followed by surgery. Results: Among 900 patients, 103 were treated with curative intent. Mean age of patients was 54 years, and 100% of the patients presented with complaint of dysphagia. Surgery as a single modality of treatment was done in 57% of cases, and the remaining underwent combined modality treatment. Transthoracic and transhiatal approaches were used in 95% and 5% of cases, respectively. Nodal sampling, two-field (2-FD), and three-field lymphadenectomy (3-FD) were done in 18%, 59%, and 20% of cases, respectively. A majority of patients had pathological stage III disease (46.6%). In-hospitality mortality was 5%, and anastomotic leakage rate was 14%. In 87% of patients, R0 resection was achieved. Overall, 4-year survival was 20%. A R0 resection, early-stage disease and 3-FD favored the survival advantage (P < 0.05). Conclusion: The mortality, complication, and survival results were in the acceptable range. R0 resection and radical nodal dissection should be standard practice.
