Medical science book-the common surgery learn:Colon cancer

(A)big body appearance cent type
1.Lump type colon cancer 2.Gradually type colon cancer 3.Ulcer type colon cancer
1.Lump type(the type, soft cancer of condy-loma accuminata) tumor to bowel chamber inside grow, lump body more big, present hemisphere form or globosity to swell up, easily fester to bleed combine after hair infection, bad dead.That type of most divide higher, invade smooth small, growth more and slowly, the good hair is at the right half colon.
2.Invade the smooth type(the Suo narrow type, hard cancer) tumor surrounds bowel wall to invade smooth, the fiber organization which has already shown Zhao respond, follow to glue a film a bottom a growth, the quality is harder and easily cause a bowel chamber narrow with Geng Zu.The type's cell divides degree lower, malignant degree Gao, appear to transfer early.Deliver right half colon so with the far large intestine.
3.The ulcer type tumor also outside invades toward the bowel wall toward the bowel wall deep growth smooth, can immediately appear ulcer in early days, the edge swell up, the bottom deeply sank, easy occurrence bleed, infection, and easily wore deeply bowel wall.The cell divides degree low, transfer early.BE the most familiar type in colon cancer, the good hair is at the left half colon, rectum.
(Two)organize a credit type
1.Gland cancer most colon cancer are gland cancers, share three quarter around, the gland cancer cell can recognize, arrange into the gland tube form or gland a bubble a form, pressing it to divide degree can is divided into x-rated, the Ⅲ class divide the most bad, cell alignment is a slice of form or Suo form.
2.Glue the liquid cancer cancer cell secretes to glue a liquid, can push the cell nucleus to the part(form ring, have already called to print to quit a cell cancer) in the cell, at cell outside it is thus clear that have already glued liquid and fiber organization to respond inside quality, the cancer cell is in the slice the form glue the liquid islet form.Divide low, to compare a gland cancer behind bad.
3.DO not divide a cancer cancer cell small, shape and arrange anomaly, easily invade small afferent and lymphoid tube, invade smooth obvious.Divide very low, to the most bad behind.
(Three)the clinical cent expect
Ⅰ Period:(the Dukes AN expect)The cancer limits at inside bowel wall
A0 periods:The cancer limits at to glue a film
A1 period:The cancer limits at to glue film bottom layer
A2 periods:The cancer invade and the bowel wall muscle layer wore to deeply strach a film
Ⅱ Period:(the Dukes B expect)The cancer invade smooth to the outside of the bowel wall
Ⅲ Period:(the Dukes C expect)The companion has lymphatic gland to transfer
C1 period:The neighboring district is lymphoid to transfer(bowel side)
C2 periods:The distance is lymphoid to transfer(fasten a film)
Ⅳ Period:(the Dukes D expect)Have already been far dirty to transfer
(Four)proliferation transfer
