*p < 0.05, Fisher�s exact test
T1, Tumor 2 cm or less in greatest dimension; T2, Tumor more than 2 cm but
not more than 4 cm in greatest dimension; T3, Tumor more than 4 cm; T4,
Tumor invades surrounding organs.
pN0, Pathologically no regional lymph node metastasis; pN1, Pathologically
metastasis in a single ipsilateral lymph node, 3 cm or less in greatest dimension;
pN2, Pathologically metastasis in a single ipsilateral lymph node, more than 3
cm but not more than 6 cm in greatest dimension; or in multiple ipsilateral
lymph nodes, none more than 6 cm in greatest dimension; or in bilateral or
contralateral lymph nodes, none more than 6 cm in greatest dimension. |
