Survival comparison among clinical stage I MT (LND−1), histologically node negative stage I MT (LND+1) and histologically node positive stage IIIC MT (LND+3C). Kaplan–Meier curves for the difference in overall survival between LND−1, LND+1 and LND+3C. Overall 5-year survival was 96.8% for LND−1, 98.6% for LND+1 and 83.3% for LND+3C (P=0.38).
