Objectives:
The ligation of thoracic duct interrupts the normal lymphatic circulation. Whether the ligation of thoracic duct would affect tumor recurrence and patient survival is unclear.
Methods:
The correlations between prophylactic thoracic duct ligation (PLG) and prognosis were examined in patients with esophageal squamous cell carcinoma. Patients who received Ivor Lewis or McKeown esophagectomy with systemic lymph node dissection and R0 resection between 2003 and 2013 in Sun Yat-sen University Cancer Center were included in the study.
Results:
A total number of 473 and 462 were included in the PLG group and non-prophylactic thoracic duct ligation (NPLG) group, respectively. The PLG group had a lower 5-year survival rate (48.2% vs 61.6%, P < .001). After a 1:1 propensity score matching, 874 cases (437 pairs) were included and the survival analysis showed that PLG was associated with worse 5-year cumulative survival of 48.6% vs 61.6% in those patients without ligation (P < .001). The multivariate analysis revealed that PLG was an independent factor for poor prognosis after esophagectomy (hazard ratio, HR = 1.56; 95% confidence interval, 95% CI, 1.26-1.93, P < .001). Additionally, PLG was associated with regional lymph node relapse (P = .015).
Conclusions:
PLG should not be performed routinely if no sign of thoracic duct rupture or tumor invasion were identified.
