How to treat colorectal cancer? The following experts will introduce you to the relevant knowledge on how to treat colorectal cancer.

The key to treating colorectal cancer lies in early detection and early diagnosis.

(1) Surgical treatment: The only radical cure for colorectal cancer is early resection of the tumor. If metastasis is found during exploration, but the diseased intestinal curve is still free, the colorectal cancer should be removed in principle to avoid intestinal obstruction in the future. On the other hand, the tumor is often eroded, bleeding, or accompanied by secondary infection. Resection can improve the overall condition. For patients with extensive cancer metastasis, if the diseased intestinal segment can no longer be removed, palliative surgery such as fistula or shortcut should be performed.

(2) Chemotherapy: After radical resection of colorectal cancer, about 50% of cases still have recurrence and metastasis, mainly because the hidden metastatic lesions were not discovered before surgery or the lesions were not completely removed during surgery. Therefore, before laparotomy, intra-intestinal chemotherapy for tumors or preoperative enema for rectal cancer can prevent the spread of cancer cells and kill and eliminate cancer cells. Continuing chemotherapy after surgery may increase the 5-year survival rate after radical resection.

5-Fluorouracil is the first choice for chemotherapy of colorectal cancer. It is usually given by intravenous injection, 12-15 mg/kg, once a day for 5 days, and then the dose is halved, once every other day, until obvious toxic symptoms such as vomiting and diarrhea appear. A total of 8-10 g is considered a course of treatment. This method has a slightly milder reaction and is suitable for outpatient treatment.

In addition to gastrointestinal reactions, the toxic symptoms of chemotherapy can also include bone marrow suppression, which requires close observation. In addition, the commonly used chemotherapy drugs include furanflurouracil, eufodine, cyclophosphamide, bischloroethyl nitrosourea, cyclohexyl nitrosourea and methyl nitrosourea.
