- •We validated the predictive impact of the total tumor size on adenocarcinoma subtype and lymph node involvement.
- •Total tumor size of 1.15 cm achieved a sensitivity of 84.44% and specificity 81.4% for differentiating AIS/MIA from IAC.
- •Total tumor size of 1.05cm achieved a sensitivity of 100% and specificity 50% for lymph node involvement.
- •The systematic nodal dissection would be unnecessary if total tumor size is ≤1 cm in diameter in lung adenocarcinoma patient.
