How to effectively treat colorectal cancer

With the advancement of science and human development, treatment methods have been significantly improved. Colorectal cancer is a malignant tumor disease, and there are many ways to treat it. Doctors will choose the treatment method suitable for the patient based on the patient's characteristics. What are the treatment methods? Let us understand what will help the recovery of the disease.

It is generally believed that preoperative radiotherapy is more beneficial because it is not damaged by surgery, the local blood supply and oxygen conditions are better, and the chance of iatrogenic spread or metastasis is also small. Therefore, it is believed that preoperative radiotherapy is more beneficial and can reduce the tumor stage and reduce intraoperative bleeding. Postoperative radiotherapy can reduce the local recurrence rate of patients and improve the survival rate.

1. Preoperative radiotherapy: Preoperative radiotherapy has the following effects: ① Improve surgical resection rate; ② Reduce lymph node invasion rate and percentage of advanced patients; ③ Reduce distant metastasis; ④ Reduce local recurrence rate and improve survival rate

2. Postoperative radiotherapy: Postoperative radiotherapy has the following effects: ① Reduce local recurrence rate: Patients who start postoperative radiotherapy early will have better results. ② Improve survival rate: The 5-year survival rate of patients who receive postoperative radiotherapy is significantly higher than that of patients who receive surgery alone.

3. "Sandwich" radiotherapy: In order to give full play to the advantages of preoperative radiotherapy and postoperative radiotherapy and overcome the shortcomings of both, the method of preoperative radiation-surgery-postoperative radiation is adopted, which is called the "sandwich" method.

4. Intraoperative radiotherapy: In order to increase the radiation dose of tumor tissue and reduce unnecessary radiation of normal tissue, there have been reports in recent years of using intraoperative radiotherapy under direct vision.

Through the above understanding, we know the treatment methods of colorectal cancer. I hope everyone can continue to enrich their medical knowledge. Family members must be mentally prepared for the patient, have an optimistic mental attitude, be full of confidence in life, and actively cooperate with the doctor's treatment, so that our bodies can recover soon.
