The impact of thoracic duct resection on the long-term body composition of patients who underwent esophagectomy for esophageal cancer and survived without recurrence.

ABSTRACT:

Background

We have reported the possible benefits of radical esophagectomy with thoracic duct (TD) resection in elective esophageal cancer surgery. However, the effect of TD resection on the long-term nutrition status remains unclear.

Methods

Patients who underwent esophagectomy at Keio University between January 2006 and December 2018 were included, and those who had no recurrence for more than three years were evaluated. Changes in each body composition (muscle mass and body fat) were comparatively assessed between those who underwent TD resection or not, before and at, one, three and five years after surgery. Computed tomography images were analyzed on postoperative year 1, 3 and 5.

Results

This study included 217 patients categorized in the TD-resected (TD-R) (156 patients) and TD-preserved (TD-P) (61 patients) groups. The loss of muscle mass was comparable between the groups. On the other hand, the loss of adipose tissues was significantly greater in the TD-R group than in the TD-P group at one and three years after surgery, while there was no statistical difference five years after surgery. Additionally, among patients with cT1N0M0 disease in whom survival advantage of TD resection has been reported previously, the loss of muscle mass did not differ between each group.

Conclusions

The change of muscle mass between the two groups was comparable. Although body fat mass was reduced by TD resection, it eventually recovered in the long term. In patients with esophageal cancer, TD resection may be acceptable without significant impact on body composition in the long term.

Project description:Background Whether extended robot-assisted esophagectomy with thoracic duct resection (RAE-TDR) has a favorable effect on esophageal cancer patients is not yet known. This study sought to analyze the safety and efficiency of RAE-TDR. Methods From January 2019 to July 2020, 73 thoracic duct (TD)-resected and 127 TD-preserved consecutive patients who received standard RAE McKeown surgery were enrolled in this study. The perioperative-related indicators of recurrence-free survival (RFS) and overall survival (OS) at 1-year were compared between the 2 groups. Results In relation to morbidity, the Clavien–Dindo (CD) classifications for grades greater than or equal to II–III were similar between the 2 groups (P>0.05). The number of retrieved total lymph nodes (LNs) and mediastinal nodes were significantly higher in the TD-resected group than in the TD-preserved group (total lymph nodes: 29.0±11.1 vs. 25.1±8.5, P=0.006; mediastinal nodes: 19.5±8.0 vs. 16.1±5.5, P=0.002). Additionally, more metastatic TD-related LNs were harvested in cT3–4 patients (2.3±3.7 vs. 1.7±2.8; P=0.21). The rates of LN recurrence and local recurrence were similar between the 2 groups (LN recurrence: 6.8% vs. 7.1%, P>0.99; local recurrence: 1.4% vs. 2.4%, P>0.99). The OS and RFS at 1-year were equivalent regardless of the TD procedure at each stage (P>0.05). However, the rate of hematogenous metastasis in the TD-resected group was significantly elevated (17.8% vs. 7.9%; P=0.034). Conclusions RAE-TDR may help to improve total and metastatic LN harvest, especially in patients with advanced esophageal squamous cell carcinoma (ESCC) without increasing the intra- and post-operative adverse events. However, RAE-TDR did not lead to a decrease in the local recurrence rate within the short-term follow-up period. Whether the increase in distant metastasis rate in the TD-resected group was associated with relevant immune system damage is unclear. Thus, nonselective RAE-TDR is not routinely recommended.

Project description:ObjectivesEven underwent radical resection, some patients of thoracic esophageal squamous cell carcinoma (ESCC) are still exposed to local recurrence in a short time. To this end, the present study sought to differentiate patient subgroups by assessing risk factors for postoperative early (within one year) local lymph node recurrence (PELLNR).MethodsESCC patients were selected from a prospective database, and divided into high- and low-risk groups according to the time of their local lymphatic recurrence (within one year or later). Survival analysis was conducted by the Cox regression model to evaluate the overall survival (OS) between the two groups. The hazard ratio (HR) and 95% confidence interval (CI) of different variables were also calculated. Logistic regression analysis was used to explore the high-risk factors for PELLNR with the odds ratio (OR) and 95% CI calculated.ResultsA total of 432 cases were included. The survival of patients in the high-risk group (n = 47) was significantly inferior to the low-risk group (n = 385) (HR = 11.331, 95% CI: 6.870-16.688, P < 0.001). The 1-year, 3-year, and 5-year OS rate of the patients in high/low-risk groups were 74.5% vs. 100%, 17% vs. 88.8%, and 11.3% vs. 79.2%, respectively (P < 0.001). Risk factors for local lymph node recurrence within one year included upper thoracic location (OR = 4.071, 95% CI: 1.499-11.055, P = 0.006), advanced T staging (pT3-4, OR = 3.258, 95% CI: 1.547-6.861, P = 0.002), advanced N staging (pN2-3, OR = 5.195, 95% CI: 2.269-11.894, P < 0.001), and neoadjuvant treatment (OR = 3.609, 95% CI: 1.716-7.589, P = 0.001). In neoadjuvant therapy subgroup, high-risk group still had unfavorable survival (Log-rank P < 0.001). Multivariate analysis demonstrated that upper thoracic location (OR = 5.064, 95% CI: 1.485-17.261, P = 0.010) and advanced N staging (pN2-3) (OR = 5.999, 95% CI: 1.986-18.115, P = 0.001) were independent risk factors for early local lymphatic recurrence. However, the cT downstaging (OR = 0.862, 95% CI: 0.241-3.086, P = 0.819) and cN downstaging (OR = 0.937, 95% CI: 0.372-2.360, P = 0.890) for patients in the neoadjuvant subgroup failed to lower PELLNR. The predominant recurrence field type was single-field.ConclusionsThoracic ESCC patients with lymph node recurrence within one year delivered poor outcomes, with advanced stages (pT3-4/pN2-3) and upper thoracic location considered risk factors for early recurrence.
