Can colorectal cancer be cured?

The treatment of colorectal cancer has always troubled the patients and their families. How long can a patient with colorectal cancer live? Can colorectal cancer be cured? Such questions are often asked by the patients' families. Can colorectal cancer be cured? The answer to such questions is uncertain and difficult to answer. Colorectal cancer patients must actively cooperate with the doctor's treatment and maintain an optimistic mood, which is conducive to the recovery of colorectal cancer. So, what are the treatments for colorectal cancer?

The main treatments for colorectal cancer are as follows:

1. Radical surgery: Radical surgery or absolute radical surgery refers to the complete removal of the tumor and the clearance of regional lymph nodes during surgery, with no residual cancer at any of the resection margins as determined by histological examination. This is the treatment method for colorectal cancer.

2. Local resection: Local resection refers to the removal of part of the intestinal wall in the area where the tumor is located. It is suitable for early superficial colon cancer and benign tumors that are confined to the mucosa or muscularis mucosa. Some malignant tumors are located in the muscularis mucosa and the submucosa. In a few cases, there may be regional lymph node micrometastasis and metastasis. Local resection alone may not meet the requirements of radical cure. Such cases should be treated with caution. The resection range of local resection can include the entire layer of the intestinal wall, and the cutting edge should be no less than 2 cm away from the tumor. Endoscopic mucosal resection or resection of the mucosa, submucosa and part of the muscularis mucosa through anal dilation can also be performed. This is the treatment method for colorectal cancer.

3. Palliative tumor resection: Absolute palliative tumor resection refers to those with residual tumors visible to the naked eye. For example, if there is metastasis to the peritoneum, liver, and non-regional distant lymph nodes, it is impossible to remove all metastatic lesions. Relative palliative tumor resection (or relative radical surgery) is a radical procedure. Although the tumor is completely removed by naked eye during the operation, postoperative histology confirms that there is a resection margin, residual tumor base, or metastasis in the highest level lymph nodes removed. This is the treatment method for colorectal cancer.

4. Bowel segment resection: Bowel segment resection refers to the removal of a certain length of intestinal tube including the tumor. Generally, the upper and lower cutting margins should not be less than 5.0 cm from the tumor. Tumor bowel segment resection should include corresponding mesentery resection, that is, to meet the requirements of dl. It is suitable for larger benign tumors and cancers that are partially limited to the submucosal and superficial muscle layer without lymph node metastasis. This is the treatment method for colorectal cancer.

5. Combined organ resection: Combined organ resection for colon cancer is suitable for cases where adjacent organs are invaded, and is often used as a radical surgical procedure. However, in some cases, such as when the tumor invades other organs, obstruction or perforation may occur, or internal fistula has formed, and the patient has a long postoperative survival expectation, even if distant metastasis has occurred, palliative combined organ resection can still be performed. This is a treatment method for colorectal cancer.

The above is an introduction to the treatment methods of colorectal cancer. I hope it will be helpful to patients with colorectal cancer. Patients with colorectal cancer must actively cooperate with the doctor's treatment, establish reasonable eating habits and maintain an optimistic attitude, which is conducive to the rehabilitation treatment of colorectal cancer.
