Summary: The objective of this study was to investigate the factors influencing the prediction of the Ki-67 index in patients with pituitary adenomas (PAs). Data from 178 patients confirmed with PAs were retrospectively analyzed, and it was found that age, rich blood supply to the tumor, and erosion of the dorsum sellae bone were influencing factors for predicting the Ki-67 index. Suitable prediction models were developed and validated, providing potential for personalized treatment for PA patients.

Summary: This study retrospectively analyzed the outcomes of the transsphenoidal approach for nonfunctioning pituitary adenomas treated at a single institute. The study found that the transsphenoidal approach is an effective and safe treatment, improving visual impairment and restoring endocrine function. Diabetes insipidus was the most common complication, and complete resection during surgery helped to lower the risk of recurrence.

Summary: This study characterized the clinical features and natural history of nonfunctioning pituitary microadenomas and found that they are generally benign. It suggests that the initial MRI follow-up interval for these tumors can be extended up to 3 years, unless there are specific concerns.

Summary: Objective data on pituitary function before and after transsphenoidal surgery in nonfunctioning pituitary adenomas were inconsistent. This study found that adrenocorticotrophic hormone deficiency increased significantly at 1 year postoperatively, while other axis function changes were not significant. Therefore, continuous individual evaluations are needed during longer follow-up of patients operated for NFPA.

Summary: This study analyzed 375 patients with residual nonfunctioning pituitary adenomas (NFPAs) who were treated with stereotactic radiosurgery (SRS) and compared the outcomes between early treatment and treatment at progression. The results showed that there was no significant difference in tumor control and preservation of hormonal/visual function between SRS at residual NFPA progression and adjuvant SRS. Deferring radiosurgical management to the time of radiological progression could prolong the onset of radiosurgically induced pituitary dysfunction.

Summary: The study on the natural history of asymptomatic nonfunctioning pituitary adenomas (NFPAs) with optic nerve compression showed that close follow-up and timely surgical intervention can effectively prevent visual and endocrine issues for cases with optic nerve compression, and conservative management is also acceptable for these tumors. Careful follow-up is necessary for tumors with cavernous sinus invasion.

Summary: This study found that ADAM22 is overexpressed in pituitary adenoma (PA) and promotes its growth and invasion through activating the ITGB1 signaling pathway. It also revealed that PKA may regulate ADAM22 levels through phosphorylation and delaying degradation. ITGB1 may be a potential therapeutic target for PA.

Summary: This study explored DNA methylation patterns associated with tumor progression in patients with nonfunctioning pituitary adenomas (NFPAs). The results showed that some methylation sites were associated with tumor progression and could potentially serve as biomarkers for early identification of tumor progression.

Summary: This study retrospectively analyzed the clinical and pathological characteristics of patients with refractory pituitary adenomas. The findings showed that refractory PAs are unresponsive to conventional treatments and have a poor prognosis. Tumor size, invasive rate, and tumor growth rate were significantly higher in refractory PAs. A TGR >2.2% per month, Ki-67 index >= 3%, and EGFR overexpression may be independent predictors of clinical refractoriness.

Summary: Recovery from AGHD after initial TSS is more likely in younger female patients with higher peak GH levels assessed by preoperative PPT. Patients aged <= 62.2 years and with a peak GH level of >= 0.74 μg/L based on preoperative PPT are likely to recover from AGHD.

Summary: In this study, lower zip code-level SES was associated with more severe disease at the time of diagnosis for NFPA patients, but there were no significant differences in short-term postoperative complications. Patients with higher zip code-level SES had higher rates of gross-total resection.

Summary: Following gross total resection of nonfunctioning pituitary adenomas, the 10-year chance of recurrence is low and the need for treatment even lower. After subtotal resection, upfront radiation therapy may prevent progression, but even without it, the need for intervention at 10 years is only approximately 20%, warranting a period of observation to prevent unnecessary prophylactic radiation therapy. Tumor volume > 1 cm(3), Knosp score >= 3, and Ki-67 >= 3% may prompt closer follow-up or justify early prophylactic radiation therapy.

Summary: This study aimed to report the characteristic of tumor regrowth after gamma knife radiosurgery (GKRS) and outcomes of repeat GKRS in nonfunctioning pituitary adenomas (NFPAs). The study found that parasellar invasion and tumor margin dose (<12 Gy) were independent risk factors for tumor regrowth after GKRS. Repeat GKRS might be effective on tumor control for selected patients.

Summary: This study indicates that transnasal sphenoidal surgery is a safe therapeutic option for elderly patients with nonfunctioning pituitary adenomas, even in the presence of comorbidities and high anesthetic risk. Adenoma size is a determinant of peri-surgical complications, while the likelihood of normalizing at least one pituitary hormone deficiency is significantly associated with younger patient age.

Summary: The first line of treatment for nonfunctioning pituitary adenoma (NFPA) is surgery. Adjuvant radiotherapy or surveillance and new treatment (second surgical operation or salvage radiotherapy) in case of recurrence are options discussed at the multidisciplinary tumor board. The purpose of this study was to evaluate the therapeutic outcome for each option. Results showed that adjuvant radiotherapy was not superior to salvage radiotherapy in preventing recurrence, therefore salvage radiotherapy is recommended in case of recurrence or progression to avoid a second surgical operation.
