Many of the clinical staging of pancreatic cancer, each with its representation, but also reflect its characteristics, the key issue there per lymph node metastases. At present there is no a general classification, now few of the more commonly used classification method is introduced:
(1) Hermreck's staging (1974) Section I: tumor limited to pancreas
Section E of the clinical stage of pancreatic cancer: tumor invades adjacent tissue only,
Section III: Regional lymph node metastasis has been
Section N of: liver and other distant metastases have been
(2) Adama stage anatomy amended (1983)
Anatomical staging of pancreatic cancer
T1: <2 cm, confined to the pancreas
T2: 2 6 cm, confined to the pancreas
T3:> 6 said: violations outside the adjacent pancreatic tissue
NO: per lymph node metastasis
N1: when the laparotomy only one lymph node region N2: two regional lymph nodes have been violated
N3: Clinically, can reach regional lymph nodes
(3) Classification of pancreatic cancer Li Qian (1989)
Of clinical stage I pancreatic cancer: T1NOMO
Tl: tumor in the pancreas, solitary, usually <2 cm
NO: per lymph node metastasis
MO: Yuan blood supply transfer
H phase: T2N1MO
T2: Pancreatic cancer is beyond the pancreas package, generally <5 cm, has invaded adjacent tissue, bile duct or duodenum, or bile duct lesions in multiple
Nl: the first leg of lymph node metastasis has been
Dish of: T2-3Nl-2MO
T3: Cancer has invaded the stomach, spleen or abdominal tissues such as the portal vein after pancreatic or
Mesenteric vein, pancreas, usually> 5 cm
N2: second leg of the lymph nodes have been transferred
N on: T2-3Nl-3M1
T4: Cancer has been the consolidation with the surrounding tissue
N3: lymph node metastasis has been the third leg
