Molecular Diagnosis of MACC1 Status in Lung Adenocarcinoma by Immunohistochemical Analysis

Representative IHC staining. A: Positive staining for MACC1 with brown stained cytoplasm is shown at low power (original magnification ×40), the IS and PS were judged to be 3 and 3, respectively, in this sample. Therefore, the IHC of this tumor was assumed to be positive, with a score of 6. B: Representative IHC staining of tumors at high power (original magnification ×400). C: Negative staining for MACC1 is shown at low power. D: Negative staining for MACC1 is shown at high power.
