Metastasis rate of poorly differentiated carcinoma

Poorly differentiated cancer refers to the pathological grading of malignant tumors. Pathologists grade tumors according to their pathological morphology, which can indicate the degree of malignancy and provide a basis for clinical treatment and prognosis. Pathological grading is mainly based on the degree of differentiation, heteromorphism and mitotic figures of malignant tumors. The three-level method is the most commonly used at this stage. The three levels are highly differentiated, moderately differentiated and poorly differentiated. Generally, the more highly differentiated the cells are, the closer they are to normal cell performance, and the lower the degree of differentiation, the more obvious the heteromorphic nature of the cells, and the difference between the performance of normal cells is very large. At the same time, it also shows that the degree of malignancy is very high and the prognosis is relatively poor.
