- Abstract: BACKGROUND: Non-functioning pituitary adenomas (NFPA) are clinically challenging because they present at a late stage with local mass effects or hypopituitarism. Surgery for non-functioning pituitary adenoma requires a special strategic approach for both minimal morbidity and radical resection. However, the clinical predictive factors associated with recurrence are limited. Here, we investigated optimal treatment of non-functioning pituitary adenoma. METHODS: We enrolled 289 patients who presented with non-functioning pituitary adenoma between January 2000 and January 2012 and who had received follow-up for at least one year for this retrospective study. Of these patients, 152 were male and 137 were female, with a median age of 51 years (range 15.79 years) and a median follow-up of four years (range 1.12.6 years). Characteristics of patients and tumors were reviewed with electronic medical records and radiologic images, retrospectively. RESULTS: Of the tumors, 193 were gross-totally resected, 53 were near-totally resected, and 43 were sub-totally resected. The extent of resection and adjuvant radiotherapy were both statistically significant prognostic factors of recurrence. Immunohistochemistry of tumor specimens did not yield consistent results. CONCLUSION: With a high rate of recurrence, NFPA should be closely followed-up over a long-term period. Improvement of surgical techniques with advanced surgical equipment and adjuvant radiosurgery would lead to reduce the recurrence rate and improve patients' outcome.
