Long-term outcomes following “presumed” total parathyroidectomy for secondary hyperparathyroidism of chronic kidney disease

Aim. The most efficacious surgical treatment for renal hyperparathyroidism is still subject of research. Considering its low incidence rate of long-term relapse, “presumed” total parathyroidectomy without autotrasplantation (TP) may be indicated for secondary hyperparathyroidism (2HPT) in patients with chronic kidney disease (CKD), not eligible for kidney transplantation. The aim of this study was to analyse the TP long-term results in 2HPT haemodialysis (HD) patients. Method. Between January 2004 and October 2009, 25 2HPT HD patients, not eligible for kidney transplantation, underwent TP of at least four parathyroid glands. Clinical status and intact parathyroid hormone (iPTH) serum levels were assessed intraoperatively and during a 36-month follow-up. Results. TP improved the typical clinical symptoms and a significant reduction of iPTH serum levels was achieved in each patient. Aparathyroidism was never observed; in case of severe postoperative hypocalcemia, hypocalcemic seizures were never reported and the long-term recurrence rate was 8%. Only one patient received a kidney transplantation. Postoperative cardiovascular events (hypertension, peripheral artery disease, arrhythmia, coronary or cerebrovascular disease) were observed in 32% of cases and mortality rate was 16%. Conclusions. Considering its low long-term relapse rate and the absence of postoperative aparathyroidism, TP may still be considered the treatment of choice in patients with aggressive forms of 2HPT or of advanced dialytic vintage, with no access to renal transplantation. In case of postoperative hypoparathyroidism, hypocalcaemia can be effectively managed by medical treatment.

Indications for and limits of conservative surgery in breast cancer

Improvements in diagnostic techniques and, above all, breast cancer screening campaigns - essential for early diagnosis - have enabled the objectives of conservative surgery to be pursued: disease control, no or low incidence of recurrences and an excellent esthetic result. However, to reach these objectives, it is essential to ensure a careful evaluation of the medical history of every patient, a detailed clinical examination and the correct interpretation of imaging. Particular attention should be paid to all factors influencing the choice of treatment and/or possible local recurrence: age, site, tumor volume, genetic predisposition, pregnancy, previous radiotherapy, pathological features, and surgical margins. The decision to undertake conservative treatment thus requires a multidisciplinary approach involving pathologists, surgeons and oncological radiologists, as well, of course, as the patient herself.
