Colorectal cancer Prevention and Prognosis
Prevention for Colorectal cancer is to reduce the incidence, include as follow:
1, to avoid long-term consumption of high fat food, and more into the fiber-rich foods, to maintain patency stool.
2, more consumption of fresh vegetables, fruits, garlic, tea and other natural suppressor of food, adequate vitamin A, B12, C, D, E and folic acid.
3. Not to smoke and drink. Smoking and alcohol is produced by colorectal cancer stimulating factor gene.
4, positive control precancerous lesions of intestinal polyps, in particular, intestinal polyps in patients with hereditary family shall be removed as soon as possible; strong control of schistosomiasis and schistosomiasis granuloma.
5, on the genetic susceptibility to cancer and cancer family history of precancerous population census should be conducted regularly; recent progressive wasting and changes in bowel habits, and should also be an early line on the check, with a view to early detection.
6, for early colorectal cancer after surgery or radiotherapy in patients should be regularly reviewed, long-term conditions should be given to the consolidation of Fuzheng anti-cancer traditional Chinese medicine treatment, prevention of recurrence.
Colorectal cancer Prognosis is best in common digestive tract cancer, and may be related to its biological behavior. The factors that to effect the prognostic of colorectal cancer are:
1, clinical factors:
1) Age: younger patients with colorectal cancer the prognosis is poor, and young patients with no clinical symptoms, poorly differentiated adenocarcinoma of the mucus more.
2) tumor: a lot of research found that the prognosis of colon cancer than rectal cancer, and lymph node metastasis in patients Dukes'C period better than the prognosis of colon cancer. Prognosis of colorectal cancer are closely related with the lesion location.
3) clinical manifestations of the tumor: tumor diameter, tumor-infiltrating fixed, external intrusion may affect the prognosis.
4) clinical stages: the late period of disease and poor prognosis.
2, the biological characteristics
1) carcinoembryonic antigen (CEA): in B, C phase patients, the possibility of recurrence with preoperative CEA concentration, CEA content and inversely proportional to the degree of tumor differentiation.
2) tumors and chromosome ploidy: the degree of malignancy of cancer cells depends on the cancer cell DNA content, the composition of ploidy, proliferation and chromosomal aberrations, such as changes to varying degrees.
