Experts analyze the three most common treatments for colorectal cancer

With the continuous advancement of medical technology, the methods of treating colorectal cancer have also been greatly improved, bringing hope to colorectal cancer patients. So what are the common methods of treating colorectal cancer ? Here are some common methods of treating colorectal cancer.

In general, the common treatments for colorectal cancer are:

1. Surgical treatment: The only way to completely cure colorectal cancer is to remove the tumor at an early stage. If cancer metastasis is found during the exploration, but the diseased intestinal curve can still be 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 general 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 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, which is very effective in treating colorectal cancer. Continuing chemotherapy after surgery may increase the 5-year survival rate after radical resection. It can also be used to reduce the chance of tumor recurrence. Palliative chemotherapy is used to treat advanced tumors (spread to other parts of the body).

3. Radiotherapy: It is usually used as an additional means of surgery and chemotherapy to reduce the chance of tumor recurrence. It is a common method of adjuvant treatment for colorectal cancer. Some people believe that: ① Preoperative radiotherapy can shrink the tumor, improve the resection rate, reduce regional lymph node metastasis, intraoperative cancer cell spread and local recurrence; ② Postoperative radiotherapy: For cases of radical surgery, if the tumor has penetrated the intestinal wall, invaded local lymph nodes, lymphatic vessels and blood vessels, or there is residual tumor 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.

The above is an introduction to the common methods of treating colorectal cancer. I believe everyone has some understanding of this. Patients with colorectal cancer should choose the method of treating colorectal cancer that suits them according to their actual condition and should not choose blindly.
