The meaning of colon cancer pT2N0 is that postoperative pathology found that the cancer cells have formed invasion to the basement, but no metastasis has occurred. pT2N0 is actually a postoperative pathological analysis of colon cancer patients, in which P stands for postoperative pathological examination; T represents the depth of tumor invasion, T2 means that the cancer cells have formed an invasion of the basement but have not broken through the muscle layer; N represents the metastasis of the cancer cells, N0 means no metastasis, and N1 and N2 are used to represent metastasis if it occurs. For pT2N0 patients, although there is no metastasis, in order to reduce the chance of recurrence after surgery, they still need to take single chemotherapy drugs for treatment, such as capecitabine and other drugs, in order to eliminate the possible residual cancer cells and improve the cure rate of patients. The above drugs should be taken under the guidance of a doctor.
