There are many factors that influence exactly how long to live.
Clinically, colon cancer using TNM staging can be divided into stage I, II, III, and IV. Mid-stage rectal cancer generally refers to stage II and III rectal cancer, and the principle of treatment for patients in this stage is generally surgical resection, with surgery being the preferred treatment and postoperative adjuvant chemotherapy given accordingly based on pathology and depth of mass infiltration. In addition, rectal cancer also requires specific planning of treatment according to the patient’s age, high-risk factors, and molecular typing accordingly.
There are many factors that influence exactly how long to live after surgery for mid-stage colon cancer. The patient’s age, physical condition, degree of tumor differentiation, extent of surgical resection, degree of metastasis in surrounding lymph nodes, sensitivity to chemotherapy drugs, and whether other underlying diseases are combined, etc. The cure rate for patients with mid-stage colon cancer is relatively high. Clinical statistics show that the 5-year survival rate for patients with stage II colon cancer reaches 70%-80% after surgery, and the 5-year survival rate for stage III colon cancer is about 40%-65%.
