Treatment methods and principles for colorectal cancer

Colorectal cancer is a common malignant tumor of the gastrointestinal tract, with a higher incidence rate among people aged 40 to 65 years. The incidence rate of colorectal cancer in men is significantly higher than that in women, at about 1.6:1.

Treatment options for colorectal cancer

1. Surgical treatment: All colorectal cancers that can be removed should be treated with radical surgery as soon as possible if there are no contraindications to surgery. Radical surgery involves removing the tumor itself and completely removing the regional lymph nodes that may have metastasized. Therefore, only a thorough surgery can cure colon cancer.

2. Chemotherapy: Chemotherapy after radical surgery, also known as adjuvant chemotherapy, is an important part of the comprehensive treatment of colon cancer. The mechanism of adjuvant chemotherapy is to use chemotherapy to control and eliminate residual lesions in the body after radical surgery. Preoperative chemotherapy can reduce the stage of the tumor and increase the surgical resection rate.

3. Radiotherapy: For patients with unresectable tumors or distant metastatic lesions, local radiotherapy is also one of the commonly used methods for treating advanced colon cancer. It can shrink the tumor and improve the patient's symptoms. It is often used in combination with other treatment options.

4. Chinese medicine treatment: Currently, most of them are combined with surgery or chemotherapy for comprehensive treatment. It can reduce the side effects of chemotherapy and enhance the body's resistance to disease.

5. Other treatment methods: Immunotherapy, gene therapy, and targeted therapy are all biological treatments, and immunotherapy is currently the most widely used in clinical practice.

Treatment principles for colorectal cancer

The treatment principle of colorectal cancer is comprehensive treatment with surgical resection as the main approach, combined with chemotherapy and radiotherapy to reduce the recurrence rate after surgery and improve the survival rate. For unresectable colon cancer, neoadjuvant chemotherapy can be used. On the one hand, it can reduce the stage of the tumor and transform some unresectable tumors into resectable tumors; on the other hand, it can prolong the patient's survival time and improve the patient's quality of life.
