Stage II rectal cancer patients have a low 15-year survival rate after treatment, but there is no clear data, and the current statistics for the five-year survival rate is around 75%~80%.
Rectal cancer is a common malignant tumor caused by bad dietary habits, heredity, etc. Stage II is one of its clinical stages, which represents the tumor infiltrating into the intrinsic muscular layer; or subplasma membrane layer; or penetrating into the dirty peritoneum and so on, but there is no lymph node and distant metastasis.
In this period, surgical resection is mostly feasible, and after surgery, it can be supplemented with radiotherapy, chemotherapy, targeted therapy, etc. After active treatment, patients can obtain a five-year survival rate of about 75%~80%. After surgery, patients can obtain a five-year survival rate of about 75%~80% by paying attention to regular checkups and maintaining good living habits, which can prolong the survival period to a certain extent.
