For pathological analysis of lung adenocarcinoma, the degree of differentiation and tumor stage should be looked at.
1. Degree of differentiation: low-differentiated, middle-differentiated and highly-differentiated cancers often appear in pathological analysis of lung adenocarcinoma, and the degree of differentiation mentioned here refers to the maturity of tumor cells. Usually, highly differentiated tumors have low malignancy and better prognosis; lowly differentiated tumors have high malignancy and worse prognosis; moderately differentiated tumors have malignancy and prognosis in between.
2. Tumor staging: Tumor staging is generally used to describe the degree of tumor invasion and assess the prognosis of the tumor. Currently, the TNM staging method, published by the World Health Organization (WHO), is mostly used in clinical practice, with T referring to the primary tumor, N to the local lymph nodes, and M to the distant metastases.
It is recommended that patients consult their treating doctors after getting the pathology report, communicate with them actively and choose some appropriate treatment measures.
