How to treat advanced colorectal cancer

Today, as medicine continues to advance, many people suffer from colorectal cancer due to changes in their living environment. In fact, this is a disease that has serious effects on the body after contracting it. The following mainly introduces how to treat late-stage colorectal cancer? Let's take a look at the following introduction.

1. Surgical treatment

For patients with early colorectal cancer, surgical treatment can better remove the tumor and improve the prognosis. If cancer metastasis is found during 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, cancerous tumors often have erosion, bleeding or 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 surgical resection, about 50% of patients will have recurrence or metastasis. In that case, before laparotomy, intra-intestinal chemotherapy 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 surgery. 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. Radiation therapy

Radiotherapy is a common adjuvant treatment method used clinically to reduce the chance of tumor recurrence. 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 with 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.

In short, in life, for diseases like colorectal cancer, you must seek medical treatment in time after you are diagnosed with it, because if this disease is detected and treated early, the disease can be controlled as early as possible. If you need treatment, you still need to go to a regular hospital for regular treatment in time.
