Introduction: Pituitary adenomas are neoplasms originating in the pituitary gland. They represent 15.5% of tumor pathology of the central nervous system and their incidence is estimated at 3.4 cases per 100,000 inhabitants/year.
Objective: To evaluate the postoperative results of adenomas operated on at the Hospital Clinico de Valladolid (HCUV)
Material and Methods: Observational, transversal and retrospective study of operated adenoma from 2001 to 2016 in HCUV. Variables studied were epidemiology clinical, radiography pathology surgery radiotherapy and treatment
Results: 139 patients were evaluated, 61 (43.9%) being men with a mean age of 51 (42-63)years. The main cause of adenomas presentation was compressive symptoms (41.7%), followed by hormonal excess (26.9%) (table 1) 117 (84.2%) were macroadenomas with a mean size of 17.8 cm3 and 77.7% had suprasellar or lateral extension. The average reduction in tumor size was 32%. The immunohistochemical phenotype was performed on 64 (38.8%) tumors; the most numerous group was prolactinomas, followed by GH secreters and ACTH secreters. 11 (7.9%) patients had postsurgical complications: 8 diabetes insipidus, 2 SIADH, 1 respiratory distress. 9 patients had to undergo reoperation and 59 required radiotherapy. The long-term patient outcome was cure in 25 (18%) patients; persistence in 111 (79.9%) patients; recurrence in 2 (1.4%) patients and 1 (0.7%) patient died.
CLINICAL PRESENTATION | N (%) |
Compressive | 58 (41.7%) |
Hormonal excess | 36 (25.9%) |
Incidentaloma | 25 (18%) |
Hormonal deficiency | 5 (3.6%) |
Compressive/Excess | 8 (5.8%) |
Compressive/deficit | 3 (2.2%) |
Excess/deficit | 3 (2.2%) |
Compressive/deficit/Excess | 1 (0.7%) |
Conclusions: Pituitary adenomas are rare lesions that manifest mainly due to compressive symptoms or hormonal hyperproduction. Those who require surgery in the hands of expert surgeons have good results
