Colorectal cancer life expectancy table

The prognosis and survival time of rectal cancer vary from person to person, depending on factors such as the stage of the cancer, the patient's overall health, and treatment options. The following is an introduction to rectal cancer stages, survival rates, factors that affect prognosis, and treatment options.

1. Stages of rectal cancer: The stage of rectal cancer is an important basis for assessing prognosis. It is usually divided into stage I, stage II, stage III and stage IV according to the degree of spread of cancer cells. Early stage I and stage II rectal cancer are usually confined to the rectal wall and have better treatment effects. Intermediate stage III rectal cancer has spread to nearby lymph nodes. Advanced stage IV rectal cancer has already metastasized to distant sites.

2. Survival rate:

Stage I rectal cancer: The 5-year survival rate is about 90%. Early detection and surgical resection are key.

Stage II rectal cancer: The 5-year survival rate is about 70-80%. Treatment includes surgery and adjuvant chemotherapy.

Stage III rectal cancer: The 5-year survival rate is about 50-60%. Treatment includes surgery, radiation therapy, and chemotherapy.

Stage IV rectal cancer: The 5-year survival rate is about 10-20%. Advanced cancer is mainly treated with palliative care to delay disease progression and relieve symptoms.

3. Factors affecting prognosis: In addition to cancer stage, other factors affecting the prognosis of rectal cancer include the patient's age, physical condition, tumor location, pathological type and treatment response. Patients who are young, in good physical condition, with tumors located in the upper rectum and with a high degree of differentiation have a better prognosis. Regular review and monitoring of disease progression can help to adjust the treatment plan in a timely manner.

4. Treatment options: Treatments for rectal cancer include surgery, radiotherapy, chemotherapy, and targeted therapy. Early-stage rectal cancer is usually treated with surgical resection, which has a better effect. Intermediate-stage rectal cancer may require combined radiotherapy and chemotherapy. Advanced-stage rectal cancer mainly uses chemotherapy, targeted therapy, and palliative therapy to delay disease progression and relieve symptoms. Patients should choose a suitable treatment plan under the guidance of a doctor.

If suspected symptoms occur, you should seek medical attention in time and undergo detailed examination and treatment under the guidance of a doctor to ensure your health.
