Can rectal ca survive a few years? Rectal ca is rectal cancer. CA is the English abbreviation for cancer. Doctors often like to use "CA" instead of cancer in clinical writing. Rectal cancer is a very high incidence of anorectal disease. Malignant tumors, its occurrence has a huge impact on patients and the entire family, so how many years can rectal ca live without treatment?

　　rectal cancer survival time and mental state, psychological factors, and own physical conditions are very Big relationship, the overall 5-year survival rate after surgery is about 50%. If the lesion is confined to the submucosa, the 5-year survival rate after radical operation can reach 90％. Studies have shown that patients with liver metastasis can achieve R0 resection, and the 5-year survival rate can still reach 50％ above, should actively strive for surgical treatment opportunities.

　　The etiology of rectal cancer is still not very clear. Its incidence is related to social environment, eating habits, genetic factors and so on. Rectal polyps are also a high-risk factor for rectal cancer. At present, it is basically recognized that excessive intake of animal fats and proteins and insufficient intake of dietary fiber are high-risk factors for rectal cancer. Most of the early rectal cancer is asymptomatic, and when it grows to a certain degree, there will be changes in bowel habits, bloody stools, purulent bloody stools, tenesmus, constipation, and diarrhea.

　　The treatment of rectal cancer requires surgery, supplemented by a combination of chemotherapy and radiotherapy. Anterior resection of rectal cancer (Dixon operation) is applied to the upper rectum cancer 12 cm away from the anal margin. The sigmoid colon and most of the rectum are removed in the abdominal cavity, and the rectum under the reflexed peritoneum is free. This operation is less invasive and can retain the original anus, which is ideal.

　　If the cancer has local infiltration or the metastasis is extensive and cannot be cured, in order to relieve the obstruction and reduce the pain of the patient, palliative resection can be performed, and the intestinal segment with cancer is limitedly removed, and the rectum is closed Cut the end and take the sigmoid colon for stoma (Hartma operation). If it is not possible, only a sigmoid colostomy is performed, especially in patients with intestinal obstruction.

　　Radiotherapy plays an important role in the treatment of rectal cancer. At present, it is considered that the partial and later stage of low and middle rectal cancer, the survival period of preoperative simultaneous radiotherapy and chemotherapy followed by surgery is longer than that of first surgery and radiotherapy. For patients with rectal cancer whose pathological stage is stage Ⅱ and stage Ⅲ, postoperative chemotherapy is recommended. The total chemotherapy time is half a year.
