Introduction: In monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic leukemia (CLL), the expansion of malignant B cells disrupts the normal homeostasis and interactions between B cells and T cells, leading to immune dysregulation. CD20+ T cells are a subpopulation of T cells that appear to be involved in autoimmune diseases and cancer.

Methods: Here, we quantified and phenotypically characterized CD20+ T cells from MBL subjects and CLL patients using flow cytometry and correlated our findings with the B-cell receptor mutational status and other features of the disease.

Background: Treatment of advanced differentiated thyroid carcinoma (DTC) remains a challenge as 25-50% of patients with locally invasive or distant metastatic disease become refractory to radioiodine (RAI) therapy. Tyrosine kinase inhibitors (TKI) are increasingly used in this setting. The SELECT trial demonstrated that lenvatinib, a multikinase inhibitor, significantly improved progression free survival (PFS) compared to placebo.

Purpose: Data regarding treatment options and their efficacy for metastatic paragangliomas (mPPGL) is limited. This study aims to report a single center experience in treating mPPGL, comparing the efficacy and safety of various treatment approaches.

Methods: Retrospective analysis of patients with mPPGL treated at an Endocrinology Department of a cancer institute between January 2000 and October 2022.

Acute suppurative thyroiditis is an uncommon disorder caused by a bacterial infection, usually presenting with normal thyroid function. It is a serious condition that requires a prompt diagnosis and treatment with antibiotics and supportive measures. A 62 years-old female presented with a painful cervical induration and odynophagia a week after a fish bone had been removed from her pharynx.

Background: Treatment of advanced follicular thyroid carcinoma (FTC) is based primarily on indirect evidence obtained with multikinase inhibitors (MKI) in clinical trials in which papillary carcinomas represent the vast majority of cases. However, it should be noted that MKI have a non-negligible toxicity that may decrease the patient's quality of life. Conventional chemotherapy with GEMOX (gemcitabine plus oxaliplatin) is an off-label therapy, which seems to have some effectiveness in advanced differentiated thyroid carcinomas, with a good safety profile, although further studies are needed.

Background Differentiated thyroid cancer (DTC) is the most common endocrine cancer during childhood, and the prognosis is usually good. The 2015 American Thyroid Association (ATA) pediatric guidelines for DTC classify patients into three categories (low, intermediate, and high) that represent the risk for persistent/recurrent disease. The "Dynamic Risk Stratification" (DRS) System showed that, in adults, reassessment of disease status during follow-up was a better predictor of disease status at the end of follow-up when compared to ATA risk stratification.

Objective: The clinical relevance of solid/trabecular (ST) growth in papillary thyroid carcinoma (PTC) is unclear. In this study, we investigated the impact of any amount of ST growth on tumour characteristics and patient outcomes. Furthermore, we evaluated whether ST growth per se affected patients' prognosis in the absence of aggressive features, namely vascular invasion.

Background: Anaplastic thyroid carcinoma (ATC) is one of the most aggressive solid tumors. ATC is frequently diagnosed at advanced stages with unresectable disease and palliative care is often indicated. Recently, several patient-tailored therapies for ATC are emerging due to advances in molecular profiling of these tumors.

Purpose: Central precocious puberty (CPP) in neurofibromatosis type 1 (NF1) occurs mainly in association with optic pathway glioma (OPG), but it can also develop in the absence of OPG. The aim of this study was to analyze the prevalence of puberty disorders in children with NF1 and its association with OPG and its location.

Methods: A retrospective study of 45 children with NF1 (68.

Context: Haematopoietic stem cell transplantation (HSCT) is a therapeutic option for numerous haematologic diseases and solid tumours. Increasing indications for HSCT and reduction in associated mortality have been raising the number of paediatric HSCT survivors and their long-term toxicities.

Objective: To characterize the endocrine disorders developed after HSCT.

Introduction: Cancer survivors are at an increased risk of adverse outcomes, including thyroid neoplasms, given the high radiosensitivity of this gland. The aim of this study is to assess the incidence and timeframe of thyroid complications in cancer patients, followed systematically since their radiation therapy, and to identify risk factors for the development of hypothyroidism and thyroid cancer.

Methods: We performed a retrospective study, including 282 subjects, who received neck, craniospinal, or total body irradiation (TBI).
