Abstract

Prolactinomas in women commonly present as small intrasellar tumors, but are usually much larger in men. This discrepancy has generally been attributed to differences in the delay before diagnosis. However, studies comparing clinical and pathological correlates of growth of these tumors in both sexes are lacking. We conducted a retrospective study comparing 45 men and 51 women bearing prolactinoma to determine whether the predominance of large tumors in men was due to a delay in diagnosis or, rather, to a fundamental sex-related difference in tumor growth. Basal PRL levels (mean +/- SEM, 2789 +/- 573 ng/mL) and mean tumor diameter (26 +/- 2 mm) were significantly higher in men than in women (292 +/- 74 ng/mL and 10 +/- 1 mm, respectively; P < 0.001), but were not correlated to the age at diagnosis or the duration of symptoms. Giant tumors (n = 8) occurred in males only. The frequencies of bromocriptine-resistant tumors (30 vs.5%; P < 0.01) and invasive macroadenomas (52 vs.27%; P < 0.001) were significantly greater in men than those in women. Lastly, macroprolactinomas in males exhibited higher indexes of proliferating cells by Ki-67 immunoreactivity (2.6 +/- 1.1% of positive nuclei) than did similar tumors in female patients (0.4 +/- 0.2%; P = 0.08). We conclude that the predominance of large prolactinomas in men is due to a high frequency of rapidly growing tumors, which are often invasive and frequently bromocriptine resistant.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
