What are the clinical treatments for colorectal cancer?

Colorectal cancer is one of the common malignant tumors with a high mortality rate, second only to gastric cancer and esophageal cancer. The cause of the disease has not yet been identified. Colorectal cancer can generally be divided into early, middle and late stages, and different stages have different symptoms. But do you know something about colorectal cancer? Let's take a look at the treatment methods for colorectal cancer.

1. Surgical treatment: The only radical cure for colorectal cancer is early removal of the tumor. If cancer 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, and 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. Radiotherapy: The efficacy is still unsatisfactory. Some people believe that: ① Preoperative radiotherapy can shrink the tumor, increase the resection rate, reduce regional lymph node metastasis, intraoperative cancer cell spread and local recurrence; ② Postoperative radiotherapy: For cases that require radical surgery, if the tumor has penetrated the intestinal wall, invaded local lymph nodes, lymphatic vessels and blood vessels, or there are residual tumors after surgery but there is no distant metastasis, postoperative radiotherapy is appropriate; ③ Simple radiotherapy: For cases of advanced rectal cancer, small doses of radiotherapy can sometimes have a temporary hemostatic and analgesic effect.

3. Chemotherapy: After radical resection of colorectal cancer, about 50% of cases still have recurrence and metastasis, mainly because the hidden metastatic lesions were not found 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, kill and eliminate cancer cells. Continuing chemotherapy after surgery may increase the 5-year survival rate after radical resection.

4. Cryotherapy: Cryotherapy uses liquid nitrogen as a refrigerant. After fully exposing the tumor through an anoscope, cryotherapy uses different sizes of cryotherapy heads to contact the tumor tissue, which can effectively kill and destroy the tumor tissue. When patients in the middle and late stages cannot undergo surgery, it can be used as appropriate to reduce the patient's pain and avoid having an artificial anus. It can also achieve satisfactory results when combined with chemotherapy.

The above is some knowledge about colorectal cancer treatment that we have prepared for you today. We hope that it can help you and we feel very honored.
