Virtually all pituitary carcinomas, defined as adenohypophysial tumors exhibiting craniospinal or systemic metastases, present as invasive pituitary macroadenomas. Nearly all are functioning tumors, most commonly prolactin or adrenocorticotropic hormone-producing tumors. High-proliferation indices and p53 gene expression are more frequent in metastases than in primary tumors. The prognosis of pituitary carcinoma is poor. As an adjunct to the current functional classification of adenohypophysial neoplasms, the authors recommend a multitier "grading" scheme reflecting their aggressive potential.
