The levels had been initially derived to aid in predicting the medical final result of unique cancers, but really are more of the evaluate of time of development from the neoplastic system and are employed clinically to ascertain acceptable therapy. Molecular biomarkers are A growing number of possible to replace phase in figuring out prognosis; having said that, it is critical that the gross processing of specimens permits the exact pathological staging of neoplastic lesions.
To trace Each individual tissue specimen, the cassette with permanent tissue and study identification is placed on top rated with the metal foundation mold and integrated while in the paraffin block ahead of cooling.
