After radical surgical resection of rectal cancer, the five-year survival rate can range from 10% to 90%, which should be judged in combination with the staging and pathologic typing.
Rectal cancer is a common malignant tumor, and after surgical treatment, the five-year survival rate is more related to the TNM stage of the disease and the pathological staging of the cancer.
Clinically, according to TNM staging, rectal cancer is often divided into four stages, and the five-year survival rate of each stage is as follows: the five-year survival rate of patients with Stage I is about 90%; Stage II is about 70%; Stage III is about 40%~50%; and Stage IV is about 10%.
In addition, there is a strong relationship with the specific pathological type of the tumor. The more common one is adenocarcinoma, which accounts for about 80% of rectal cancers, with lower malignancy and higher survival rate, while mucinous adenocarcinoma and indocyte carcinoma are highly malignant, prone to metastasis, and have poorer prognosis than other types.
Therefore, for people with high risk of rectal cancer (e.g. family history, patients with intestinal polyps, etc.), they should do regular physical examination on rectal cancer, and once diagnosed, they should be treated actively.
