The total number of resected lymph node is not a prognostic factor for recurrence in esophageal squamous cell carcinoma patients undergone transthoracic esophagectomy

Abstract Background A nomogram was developed to predict lymph node metastasis (LNM) for patients with early-stage esophageal squamous cell carcinoma (ESCC). Methods We used the clinical data of ESCC patients with pathological T1 stage disease who underwent surgery from January 2011 to June 2018 to develop a nomogram model. Multivariable logistic regression was used to confirm the risk factors for variable selection. The risk of LNM was stratified based on the nomogram model. The nomogram was validated by an independent cohort which included early ESCC patients underwent esophagectomy between July 2018 and December 2019. Results Of the 223 patients, 36 (16.1%) patients had LNM. The following three variables were confirmed as LNM risk factors and were included in the nomogram model: tumor differentiation (odds ratio [OR] = 3.776, 95% confidence interval [CI] 1.515–9.360, p = 0.004), depth of tumor invasion (OR = 3.124, 95% CI 1.146–8.511, p = 0.026), and tumor size (OR = 2.420, 95% CI 1.070–5.473, p = 0.034). The C-index was 0.810 (95% CI 0.742–0.895) in the derivation cohort (223 patients) and 0.830 (95% CI 0.763–0.902) in the validation cohort (80 patients). Conclusions A validated nomogram can predict the risk of LNM via risk stratification. It could be used to assist in the decision-making process to determine which patients should undergo esophagectomy and for which patients with a low risk of LNM, curative endoscopic resection would be sufficient.

Abstract Background Although the incidence of lymph node (LN) metastasis (LNM) along the left gastric artery is high, its relationship with the prognosis in postoperative patients with esophageal squamous cell carcinoma (ESCC) is rarely reported. This study clarified the prognostic impact of LNM along the left gastric artery in postoperative patients with ESCC. Methods This study assessed data of 1521 patients with ESCC who underwent esophagectomy at the Sun Yat-sen University Cancer Center between March 1992 and March 2012. A chi-squared test and Mann-Whitney U test were used to explore the preliminary correlation between clinical factors and LNM along the left gastric artery. Univariate and multivariate Cox regression analyses were used to assess whether LNM along the left gastric artery was an independent predictor of overall survival. Kaplan–Meier analysis and the log-rank test were used to present a classifying effect based on LN status. Results LNM was observed in 598 patients (39.3%) and was found along the branches of the left gastric artery in 256 patients (16.8%). The patients were classified into two groups based on the presence of LNM along the left gastric artery. Patients without LNM along the left gastric artery had better cancer-specific survival than those with positive LNs (P < 0.001). Conclusions This study indicated that LNM along the left gastric artery was an important independent prognostic factor for long-term survival among ESCC patients (P = 0.011).

Abstract Minimally invasive esophagectomy is increasingly performed for esophageal squamous carcinoma, with advantages of improved perioperative outcomes in comparison with open esophagectomy. Lymph node dissection is one of most important prognostic factors, in esophageal squamous cell carcinoma. It is still unknown whether MIE can meet the criteria of lymph node dissection in the mediastinum, especially in T1 and T2 esophageal cancer. Here, we compared the lymph node dissection between MIE and open surgery. Methods We retrospectively reviewed the clinicopathological data from 147 patients who underwent open surgery and MIE for esophageal squamous cell carcinoma from December 2016 to January 2020. The clinicopathological data including age, gender, number of lymph node resected were analyzed. Results 68 patients underwent MIE and 79 patients underwent open surgery. The number of harvested lymph node didn’t differ between the open surgery group and MIE group (26 ± 11.9 vs 26 ± 13.4, respectively, p = 0.128). However, the number of resected lymph node in the low para-esophageal region was significantly higher in open surgery group (4.1 ± 3.9 vs 2.8 ± 2.6, respectively, p = 0.019). The number of resected lymph node in the upper mediastinal region was significantly higher in the MIE group in T1 and T2 patients (4.7 ± 3.8 vs 2.7 ± 2.9, respectively, p = 0.014). the difference was also noticed in the para-recurrent laryngeal lymph node regions (3.6 ± 2.9 vs 2.0 ± 2.3, respectively, p = 0.020). Conclusion For stages T1 and T2 esophageal squamous cell carcinoma, the lymph node dissection by MIE was comparable to that by open surgery. However, the number of harvested lymph node in the upper mediastinal region was better in the MIE group, which may indicate a better outcome. There was no difference in the postoperative complications, hospital stay and overall survival rate.
