Objectives: RET alterations are targetable oncogenic drivers in TC. Patients with TC, especially those with MTC treated with the multikinase inhibitors cabozantinib and/or vandetanib (C/V), often experience significant treatment-related side effects. Pralsetinib, a selective RET tyrosine kinase inhibitor, showed efficacy in patients with RET-altered TC from the phase 1/2 ARROW trial (NCT03037385). We present the impact of pralsetinib on PROs in patients with ...

Background: Although anti-VEGF RTKIs have been tested in patients with NETs over the last 2 decades, no study to date has benchmarked efficacy and toxicity of these drugs in this patient population.Methods: A literature search was performed to identify all phase II and phase III studies of anti-VEGF RTKIs in patients with NETs published between January 1, 2000 – July 31, 2021. Major trial databases (e.g. Medline, EMBASE, Cumulative Index of Nursing ...

Introduction and Aim: Thyroid dysfunction is the most common autoimmune endocrine disorder in women of reproductive age. Autoimmune thyroid disease is related to menstrual irregularities, anovulation and infertility. Thyroid dysfunction is thought to disrupt follicular growth and maturation. Autoimmunity may have a negative effect on fertility, independent of age. The relation between TSH (Thyroid Stimulant Hormone), thyroid antibodies and AMH (anti-mullerian hormone) is a top...

Introduction: Several studies suggest a higher risk of colorectal cancer (CRC) and colon polyps (CP) in acromegaly, however there is still controversy regarding associated factors (AF) able to contribute for its development. Data on the prevalence of CRC and CP in Portuguese patients with acromegaly are limited.Objectives: To assess the prevalence of CRC and CP in acromegalic patients and compare to the normal Portuguese population. To determine the rele...

Introduction: Acromegaly is a rare disease resulting from pathological oversecretion of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). The clinical spectrum includes cardiovascular and respiratory diseases but also increased risk of benign and malignant neoplasms.Objectives: Evaluate the prevalence of cancer and seek for associated factors in acromegaly.Methods: Retrospective study of 94 patients with acromegaly trea...

Purpose: To validate a prognostic stratification system of overall survival (OS) in stage IV pancreatic neuroendocrine tumors (pNETs) naïve of therapy by analyzing 1) prognostic parameters at the time of stage IV diagnosis; 2) the role of spontaneous tumor slope.Patients and Methods: Multicenter retrospective study including consecutive patients diagnosed with stage IV pNET from January 1997 to March 2014. Inclusion criteria were: 1. pNET w...

Propose: To screen for the presence of putative targets for new treatments in a large cohort of advanced adrenocortical cancer (ACC)Experimental design: In 40 adult stage III-IV ACC primary samples, we used comparative genomic hybridization (CGH) and hotspot gene sequencing (with Ion Torrent) to describe the presence of copy number abnormalities and mutations in more than 40 genes involved in cancer development and putative drug sensitivity (HER2; EGFR; ...

Many mechanisms are proposed for green tea’s role as anti-obesity and anti-diabetic natural product. Two of them involve the hypothalamic control of energy balance: i) high-fat diets (HFD) rich in saturated fats induce low-grade inflammation, leading to leptin and insulin resistance; ii) serotonin receptors (SR) 1B and 2C activation have anorexigenic effects, SR2C activation improves insulin sensitivity, and HFD can also impair this system. We investigated the effects of ...

Background: Mitotane antitumor efficacy is related to plasma levels. Objective responses have been associated with mitotane plasma levels >14 mg/l. However, high plasma levels >20 or >30 mg/l are at higher risk of toxicity, especially neurotoxicity. National-based survey is lacking to evaluate the frequency and severity of high mitotane plasma levels. Our aim was to retrospectively describe serious adverse events (SAE).Methods: Mitotane plasm...

Osteoporosis and diabetes mellitus type 2 (DM2) have severe health consequences, with high morbidity and mortality risks.Aims: To study the differences of the sex steroid hormones levels and the free androgen index (FAI) in DM2 men with low BMD and osteoporosis and their relationships with BMD.Materials and methods: In 317 men with DM2, the BMD (g/cm2) was evaluated at the lumbar spine (L1-L4), at t...
