✦ Synopsis
within 7 cm. For central spread: for pT1 tumors, the rate of metastasis to central lymph nodes was 0 %; for pT2, the rate of metastasis was 20.0 % to intermediate lymph nodes; for pT3, the rate of metastasis was 30.6 % to intermediate lymph nodes and 15.3 % to main lymph nodes; for pT4, the rate of metastasis was 44.4 % to intermediate lymph nodes and 22.2 % to main lymph nodes.
CONCLUSIONS.
Central lymph node dissection is not required for patients with T1 carcinomas, but proximal and distal 3-cm margins of resection are required. For T2, central lymph node dissection that includes the intermediate lymph node should be performed, as well as 5-cm proximal and distal margins of resection. For T3 and T4, central lymph node dissection including the main lymph node should be performed, as well as 7-cm proximal and distal margins of resection.
