External validation of MSKCC postoperative hypocalcaemia nomogram in Turkish papillary thyroid cancer patients
The rate of differentiated thyroid cancer (DTC) is rising all over the world. The American Thyroid Association guidelines for DTC recommend total (TT) or near-total thyroidectomy in all patients with DTC > 1 cm with the goal of leaving <1 g of remnant thyroid tissue.
The incidence of symptomatic hypocalcaemia after TT ranges from 10 to 36 %.
The ability to triage patients with TT and counsel them about postoperative hypocalcaemia based on preoperative and intraoperative parameters, is of great importance. The Memorial Sloan Kettering Cancer Centre (MSKCC) generated a nomogram that can accurately quantify the risk of postoperative hypocalcaemia in an individual patient undergoing TT. According to the authors this nomogram may be helpful in planning the length of a patient’s hospital stay and facilitate discharge planning after TT.
