ABSTRACT

Invasive pituitary adenomas have conventionally been treated with either no resection or partial resection followed by radiation therapy. The long-term follow-up of this subgroup of pituitary adenomas has not been satisfactory. The majority of these patients present back with recurrence of their tumor or side effects related to treatment with the radiation. The recent advances in surgical and skull base techniques have significantly contributed to an improved outcome for these patients. We present a modified classification for pituitary adenomas to account for the different types of invasive tumors based on the molecular biological aspects as well as the clinical behavior of these tumors.

The treatment plan of invasive pituitary adenomas is influenced by the endocrinologic aspects of the tumor cells, the neurological condition of patients at presentation, the age of the patient, and the rate of tumor growth. In this article we present a comprehensive treatment plan of invasive pituitary adenomas based upon the above-mentioned parameters. The article also covers the most recent advances in skull base and microsurgical techniques.
