Objectives/Hypothesis The aim of this study was to identify any possible predictive factors of lateral neck recurrence in patients with papillary thyroid carcinoma with no ultrasonographic and/or cytological evidence of lymph node metastasis at time of diagnosis. The influence of lateral neck recurrence on survival was also investigated. Study Design Observational retrospective study. Methods Retrospective review of clinical records of 610 patients surgically treated for papillary thyroid carcinoma with clinically negative lymph nodes at the Otolaryngology Unit of the Arcispedale Santa Maria Nuova–IRCCS, Reggio Emilia, Italy, from January 1984 to December 2008. Results Lateral neck recurrences were ipsilateral to the primary tumor in all cases and were associated with the occurrence of more aggressive histological variants and central neck metastasis. Lateral neck recurrences were more frequently observed in patients with distant metastases and were associated with a reduced disease-specific survival. Conclusion Lateral neck compartment ipsilateral to the tumor was the most common site of recurrence, with about half of cases appearing in the first 28 months of follow-up. In patients with papillary thyroid carcinoma, detection of lateral neck metastases prior to first surgery is crucial to surgical planning. Aggressive histological variants and postsurgical evidence of lymph node metastasis from papillary thyroid carcinoma in central neck compartment are associated with a higher risk of lateral neck recurrence. In these patients, a closer postsurgical ultrasound surveillance of the lateral neck compartments seems worthwhile. Level of Evidence 4. Laryngoscope, 125:2226–2231, 2015

SummaryObjective To report the Italian experience on cinacalcet use following its approval by the European Medical Agency (EMA) to control hypercalcaemia in patients with primary hyperparathyroidism (PHPT). Design Retrospective data collection from 100 patients with sporadic (sPHPT) and 35 with familial PHPT (fPHPT) followed in eight Italian centres between October 2008 and March 2011. Measurements Albumin-adjusted serum calcium, PTH, 25OHD, daily cinacalcet dose and adverse events were recorded during the follow-up (1–46 months). Results Baseline serum calcium was 2·90 ± 0·27 nmol/l in sPHPT and 2·75 ± 0·17 nmol/l in fPHPT patients (P = 0·007). The cinacalcet EMA labelling was met in 53% sPHPT and 26% fPHPT patients. High surgical risk (34%), negative preoperative imaging (19%), control of hypercalcaemia before parathyroidectomy (PTx) (24%), and refusal of PTx (19%) accounted for cinacalcet prescription in 96% of sPHPT patients. Conversely, initial treatment (34%), persistent/relapsing PHPT after surgery (31%), and refusal of PTx (14%) were the indications in 79% fPHPT patients. Cinacalcet was started at 30 mg/daily in 64% of sPHPT and 91% of fPHPT and increased until normocalcaemia was reached or side effects occurred. The final daily dose ranged between 15 and 120 mg. The majority of patients (65% of sPHPT and 80% of fPHPT) become normocalcaemic. Treatment was withdrawn in six patients because of side effects. Conclusions There is a wide heterogeneity in the prescription of cinacalcet in PHPT patients in Italy and the EMA labelling is not always followed, particularly in fPHPT patients. Cinacalcet effectively reduces serum calcium in patients with either sPHPT or fPHPT.

S. Piana, A. Frasoldati, M. Ferrari, R. Valcavi, E. Froio, V. Barbieri, C. Pedroni and G. Gardini Is a five-category reporting scheme for thyroid fine needle aspiration cytology accurate? Experience of over 18 000 FNAs reported at the same institution during 1998–2007 Objective: Fine needle aspiration (FNA) has long been recognized as an essential technique for the evaluation of thyroid nodules. Although specific cytological patterns have been recognized, a wide variety of reporting schemes for thyroid FNA results have been adopted. This study reports our experience with a five-category reporting scheme developed in-house based on a numeric score and applied to a large series of consecutive thyroid FNAs. It focuses mainly on the accuracy of thyroid FNA as a preoperative test in a large subset of histologically distinct thyroid lesions. Methods: During the 1998–2007 period, 18 359 thyroid ultrasound-guided FNAs were performed on 15 269 patients; FNA reports were classified according to a C1–C5 reporting scheme: non-diagnostic (C1), benign (C2), indeterminate (C3), suspicious (C4), and malignant (C5). Results: Non-diagnostic (C1) and indeterminate (C3) FNA results totalled 2 230 (12.1%) and 1 461 (7.9%), respectively, while suspicious (C4) and malignant (C5) results totalled 238 (1.3%) and 531 (2.9%), respectively. Histological results were available in 2 047 patients, with thyroid malignancy detected in 840. Positive predictive value of FNA was 98.1% with a 49.0 likelihood ratio (LR) of malignancy in patients with a C4/C5 FNA report. Conclusions: This five-category scheme for thyroid FNA is accurate in discriminating between the virtual certainty of malignancy associated with C5, a high rate (92%) of malignancy associated with C4, and a 98% probability of a histological benign diagnosis associated with C2. Further sub-classifications of C3 may improve the accuracy of the diagnostic scheme and may help in recognizing patients eligible for a ‘wait and see’ management.
