Medical treatment for acromegaly commonly involves receiving intramuscular or deep subcutaneous injections of somatostatin receptor ligands (SRLs) in most patients. In addition to side effects of treatment, acromegaly patients often still experience disease symptoms even when therapy is successful in controlling GH and IGF-1 levels. Symptoms and side effects can negatively impact patients' health-related quality of life.

Article Synopsis
  • The study investigates the role of the proliferation marker Ki67 in predicting postoperative outcomes for pituitary adenoma patients, focusing on tumor recurrence and regrowth.
  • A cohort of 52 patients who underwent surgery was analyzed, with 23 showing high Ki67 expression (≥3%) and the rest showing low (0-2.9%).
  • The findings suggest that while recurrence rates were similar for both groups, the regrowth of tumors was significantly higher in patients with Ki67 ≥3%, indicating the need for closer monitoring in these cases after surgery.

Purpose: Somatostatin analogs (SSAs) represent a mainstay of medical treatment for acromegaly, currently available as either intramuscular or deep subcutaneous injections. Patient-reported outcomes (PROs) are increasingly common as relevant outcomes in studies of acromegaly and its treatment, but there are no validated PRO measures available that focus on the disease burden and the impact of treatment, specifically designed for use in patients with acromegaly. We sought to develop a new and unique PRO measure, the Acromegaly Treatment Satisfaction Questionnaire (Acro-TSQ).

February 2019

Postgraduate Program in Pathology, Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA), R. Sarmento Leite, 245 - Centro Histórico, 90050-170 Porto Alegre, RS, Brazil; Neuroendocrinology Center, Complexo Hospitalar Santa Casa, Av. Independência, 75 - Independência, Porto Alegre - RS, 90035-072 Porto Alegre, RS, Brazil.

Non-functioning pituitary adenomas (NFPA) are classified as benign tumors of slow growth, but 40% of them present local invasion, a characteristic of behavior still unpredictable with the use of current tumor markers. This work aims to evaluate the tissue markers E-cadherin and NCAM, which act on cell adhesion, in tumor tissue samples of NFPA and its relationship with the degree of local invasiveness. Gene expression of E-cadherin (CDH1) and NCAM (NCAM1) was assessed by real-time PCR and tissue expression by immunohistochemistry.

Decreased TAp63 and ΔNp63 mRNA Levels in Most Human Pituitary Adenomas Are Correlated with Notch3/Jagged1 Relative Expression.

Endocr Pathol

March 2017

Post Graduation Program of Pathology, Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA), Porto Alegre, RS, Brazil.

Despite recent advances in molecular genetics, the pituitary adenoma initiation, development, progress, and the molecular basis of their unique features are still poorly understood. In this sense, it is proposed that stem cell could be involved in pituitary adenoma tumorigenesis. It is suggested that TP63 has important functions in stem cells, and it may have interplay of TP63 and Notch and its ligand Jagged in this process.
