Outcomes of Management of Pituitary Adenoma by Use of Octreotide Injections Preoperatively

Abstract

Objective:  This study explored the effects of octreotide injections in patients with pituitary adenoma pre-operatively. Material and Methods:  A quasi-observational study was conducted on 12 patients in the Neurosurgery department of the Punjab Institute of Neurosciences (PINS) with a diagnosis of pituitary adenoma. To determine the size of the tumor, we did an MRI brain with pituitary protocol and after octreotide medication. The mode of diagnosis was clinical status, MRI brain, and biopsy of the tumor. We gave 14 short-acting octreotide injections to all patients before surgery and monitored their clinical and serum IGF levels. After the completion of 14 injections of octreotide, we planned surgery for the complete excision of the tumor. We performed IGF level 2 weeks after surgery. Then, we gave long-acting octreotide injections to all patients after every 28 days. Results:  The mean age was 43 years. 67% of patients were male and 33% of patients were female. 92% of patients presented with decreased vision. 17% of patients presented to us with complete loss of vision. In 17% of patients, the vision of the patients improved. Serum IGF levels significantly decreased after short-acting octreotide, surgical excision, and long-acting octreotide therapy. Conclusion:  With the use of octreotide therapy clinical status and outcomes of management of pituitary adenoma improve.
