What stage does moderately differentiated adenocarcinoma belong to?

The staging of moderately differentiated adenocarcinoma and adenocarcinoma should be two concepts. It is a pathological diagnosis. The degree of differentiation is related to the degree of malignancy of the tumor. The malignant degree of highly differentiated adenocarcinoma is relatively low. If it is removed early, it can improve the 5-year cure rate. The malignant degree of moderately differentiated adenocarcinoma is moderate. After surgical resection, postoperative adjuvant chemotherapy can improve the cure rate. As for the stage of moderately differentiated adenocarcinoma, it should be determined according to the pathological diagnosis. It is divided into early, middle and late stages according to the size of adenocarcinoma tumor, degree of invasion, local metastasis of lymph nodes or distant metastasis. Therefore, differentiation and staging are different.
