Cellular Classification of Adrenocortical Carcinoma
Adrenocortical carcinoma can be classified into functioning and nonfunctioning tumors by clinical and biochemical assessment. Approximately 60% of adrenocortical carcinomas produce hormones. The associated clinical syndromes include the following:
Clinical validity refers to the predictive value of a test for a given clinical outcome (e.g., the likelihood that cancer will develop in someone with a positive test). It is primarily determined by the sensitivity and specificity with which a test identifies people with a defined clinical condition within a given population. Sensitivity of a test refers to the proportion of people who test positive for a clinical condition among those who actually have the clinical condition; specificity refers...
Pathology can differentiate high-grade and low-grade tumors according to the mitotic activity of the tumor. The differentiation of benign and malignant adrenocortical tumors can be achieved by determination of the Weiss score, which scores several histopathological criteria, including the following:
Number of mitoses.
Presence of atypical mitosis.
Percentage of clear cells.
