“…This model exhibited good performance and might offer potential guidance to doctors in clinical decision-making before surgery. The Ki-67 labeling index, representing a proliferative marker, has been reported as a marker of aggressiveness in PAs ( 41 ), and it is crucial to identify the Ki-67 labeling index early to allow timely diagnosis and treatment. Ugga and colleagues ( 32 ) proved that ML analysis of texture-derived parameters from preoperative T2 MRI could effectively predict the Ki-67 proliferation index class in pituitary macroadenomas.…”

“…A glândula hipófise é alvo de diversas doenças as quais promovem alterações metabólicas e dentre essas diversas patologias que podem acometê-la temos os tumores hipofisários. Os adenomas de hipófise são a 3ª causa mais comum de tumores do sistema nervoso central e atingem a população numa incidência de 3,29 a cada 100,000 habitantes 1,20,21 . São mais comuns entre a 3ª e 6ª décadas de vida, numa idade média de 45 anos, acometem ambos os sexos em igual proporção, porém os quadros clínicos se mostram mais acentuados em mulheres 7,8,20,23,25 .…”

“…Os tumores hipofisários podem acometer tanto a adeno-hipófise, que se estabelece como o quadro mais frequente sendo responsável por cerca de 10 a 15% de todos os tumores cerebrais primários, como também, mais raramente, a neuro-hipófise. Os tumores hipofisários representam 25% dos tumores cerebrais que sofrem intervenção cirúrgica e 90% dos tumores da região selar e parasselar 3,7,19,20,21,23,24,25,27 . Os sintomas mais frequentes apresentados ao diagnóstico são: déficit visual (74,6%), cefaleia (42,4%), amenorreia (22%), galactorreia (8,5%) e apoplexia (1,7%) (Figura 1) 3 .…”

“…The invasiveness of PAs increases the difficulty in achieving complete surgical excision, and the postoperative recurrence rate is 46% ( 11 ). A small proportion of PAs cannot be cured after conventional treatment and are referred to as refractory pituitary adenomas ( 12 , 13 ); these are characterized by a rapid growth rate, invasion into surrounding structures, refractory behavior to conventional treatment and severe symptoms ( 12 ). Further studies are needed to find more effective therapies for dopamine agonist-resistant prolactinomas, invasive PAs and refractory PAs.…”
