Survival for selective vs. routine lymphadenectomy in pN0 patients. Kaplan-Meier curves showing the difference in overall survival in the subgroup of patients with confirmed pN0 stage. The green line indicates cohort with selective and the blue line indicates cohort with routine lymphadenectomy. The vertical lines on the curve mark censored data. Using Log-rank test we found no significant difference in survival HR 1.17 95% CI 0.6–2.11, p = 0.6 between patients’ cohorts with selective (n = 26) and routine (n = 48) lymphadenectomy
