Descriptive surgical epidemiology of pituitary adenomas for a Hispanic population in Puerto Rico

Demographics and socioeconomic variables for patients with pituitary adenomas have been reported in the past. However, these studies included operated and nonoperated patients, in addition to microprolactinomas frequently diagnosed in women, revealing an elevated incidence among females. This study aimed to analyze the surgical incidence of pituitary adenomas for an adult Hispanic population in Puerto Rico over 6 years.

A retrospective and descriptive study was performed to investigate pituitary adenoma surgical incidence (per 100,000 people) among surgically treated pituitary adenomas in an adult (18 years or more) Puerto Rico Hispanic population. All new patients diagnosed with pituitary adenomas who underwent surgery at the Puerto Rico Medical Center between 2017 and 2022 were scrutinized. Inclusion criteria required a histopathological diagnosis of pituitary adenoma. Previously operated cases and non-Hispanic patients were excluded from the study. Patient characteristics were collected, along with the type of surgical treatment, tumor size, and secretory status.

The analysis included 143 patients operated on for pituitary adenomas. Of these, 75 (52%) patients were male, and 68 (48%) were female. The median age of the patients was 56 years (range: 18-85). The average annual surgical incidence of adult Hispanic patients with pituitary adenomas was 0.73 surgeries/100,000 people. About 79% of the patients had non-functioning pituitary adenomas. About 94% of the patients were operated on using transsphenoidal surgery.

There was no sex predominance for surgical-treated pituitary adenomas in Puerto Rico. The surgical incidence for adult pituitary adenoma remained stable between 2017 and 2022.
