  • a Continuous variables.

  • b T1, tumor invades lamina propria or submucosa; T2, tumor invades muscularis propria or subserosa; T3, tumor penetrates the serosa; T4, exposed serosa tumor invades adjacent structures.

  • c P0, no peritoneal metastasis; P1, metastasis to the adjacent peritoneum but not the distant peritoneum; P2, some metastasis to the distant peritoneum; P3, numerous sites of metastasis to the distant peritoneum.

  • d N0, no evidence of lymph node metastasis; N1, N2, and N3, metastasis to lymph nodes of groups 1, 2, and 3, respectively.
