Article Synopsis
  • A noninferiority trial was conducted to assess if omitting completion axillary-lymph-node dissection is as effective as performing it in patients with clinically node-negative breast cancer and sentinel-lymph-node metastases.
  • A total of 2,766 patients were enrolled, with 1,335 assigned to sentinel-node biopsy only and 1,205 to the dissection group, with a median follow-up of 46.8 months.
  • The results showed a 5-year recurrence-free survival rate of 89.7% for the sentinel-node biopsy-only group, suggesting that this approach may not significantly compromise patient outcomes compared to the traditional method.

Using non-human primates (NHPs), mice, and human primary cells, we found a role for interleukin-10 (IL-10) in the upregulation of the tissue-resident memory T cell (T) marker CD103. In NHPs, intravenous, but not subcutaneous, immunization with peptide antigen and an adjuvant combining an agonistic anti-CD40 antibody plus poly(IC:LC) induced high levels of CD103 Ts in the lung, which correlated with early plasma IL-10 levels. Blocking IL-10 reduced CD103 expression on human T cells stimulated in vitro with the adjuvant combination as well as diminished CD103 on lung-resident T cells in vivo in mice.

Background: In primary hyperparathyroidism, successful parathyroidectomy leads to improved bone mineral density in the majority of cases. Our aim was to further explore the relationship between hypercalciuria, kidney function, and bone recovery after parathyroidectomy.

Methods: Bone mineral density, estimated glomerular filtration rate, and 24-hour urinary calcium were analyzed before and one year after parathyroidectomy in a cohort of 150 primary hyperparathyroidism patients (119 women; median age 60 [range 30-80] years) taking part in a clinical trial.

Background: Fibroblast growth factor-23 (FGF23), a regulator of secretion of parathyroid hormone (PTH), is implicated in the development of cardiovascular disease. The role of FGF23 in primary hyperparathyroidism (pHPT) is unclear.

Methods: A total of 150 consecutive patients with pHPT were examined with ambulatory blood pressure monitoring ((24h)ABP) before parathyroid adenomectomy (PTX).

Primary hyperparathyroidism (PHPT) is a common endocrinopathy, frequently caused by a parathyroid adenoma, rarely by a parathyroid carcinoma that lacks effective oncological treatment. As the majority of cases are present in postmenopausal women, oestrogen signalling has been implicated in the tumourigenesis. Oestrogen receptor beta 1 (ERB1) and ERB2 have been recently identified in parathyroid adenomas, the former inducing genes coupled to tumour apoptosis.

Objective: Vitamin D insufficiency is common in primary hyperparathyroidism (pHPT). Patients with pHPT frequently have a reduced health-related quality of life (HRQoL). Our objectives were to evaluate whether HRQoL in pHPT is associated with vitamin D insufficiency and whether vitamin D supplementation after parathyroidectomy (PTX) could improve HRQoL.

Patients with primary hyperparathyroidism (PHPT) have higher bone turnover, lower bone mineral density (BMD), and an increased risk of fractures. They also have a high incidence of low vitamin D levels (25-OH-vitamin D <50 nmol/L) that could worsen the negative effect on the bone. In this double-blinded clinical trial, 150 patients with PHPT were randomized, after successful parathyroidectomy (PTX), to 1-year daily treatment with either cholecalciferol 1600 IU and calcium carbonate 1000 mg (D+) or calcium carbonate alone (D-).

Background: Vitamin D insufficiency may increase the risk for cardio metabolic disturbances in patients with primary hyperparathyroidism (PHPT).

Objective: To analyze the vitamin D status and indices of the metabolic syndrome in PHPT patients and the effect of vitamin D supplementation after parathyroid adenomectomy (PTX).

Design And Methods: Double-blinded, randomized clinical trial (ClinicalTrials.

Background: Primary hyperparathyroidism (pHPT) is associated with an increased risk of developing breast cancer, but little is known about the underlying factors. The aim of this study was to compare women with a history of pHPT and a reference population in terms of standard factors predictive of prognosis and response to therapy for breast cancer.

Methods: We analyzed data collected from the National Swedish Cancer Register and from two regional oncologic center registries.
