Cure rates of various stages of colon cancer

Cancer is a disease that many people are afraid of. After getting sick, they are very worried about their survival. However, diseases generally have early, middle and late stages. Undoubtedly, the early stage is the best treatment period. So for patients with early colorectal cancer, can they be cured?

Can early colorectal cancer be cured? Many patients are concerned about whether cancer can be cured if it is treated in time in the early stage. The editor tells you that the prognosis of colorectal cancer is related to many factors, and it involves the biological characteristics of the tumor. Whether it can be completely cured is also inseparable from factors such as early diagnosis and staging, treatment methods, etc.

Clinically, relevant investigations have found that if patients have already suffered intestinal obstruction when they seek medical treatment, their 5-year survival rate is generally only half of that of patients without intestinal obstruction. Patients with complications such as intestinal bleeding, perforation, and purulent peritonitis have a poor prognosis.

For patients with early-stage colorectal cancer, surgery is generally used for treatment, and of course there are certain indications. If the tumor is located more than 6 cm from the anus and there is no obvious fixation or metastasis, and the upper early-stage colon cancer is more than 12 cm from the anal verge, low abdominal resection and extraperitoneal primary anastomosis can be performed. This operation is less invasive and has a general cure rate. For patients who undergo a combined abdominal perineal resection, a permanent colostomy, i.e. an artificial anus, will be made in the abdomen. This operation removes the tumor more thoroughly and has a relatively high cure rate.

It can be seen that if it can be treated in time at an early stage, colorectal cancer is not an incurable disease. Early detection and correct treatment can cure it and it is possible to achieve long-term survival. Early rectal cancer tumors are small and have not spread or metastasized. The most effective treatment is surgical resection. The 5-year survival rate after resection of early rectal cancer can reach more than 60%.

In addition, to improve the survival rate, preparations must be made to prevent recurrence after treatment. After surgery for early-stage colon cancer, colon cancer cells in the body cannot be completely eliminated, and some will remain in the lymph nodes and other places. In addition, colon cancer surgery causes great damage to the patient's body, causing a decline in the patient's immune system function, further increasing the chance of recurrence of residual cancer cells.
