Introduction Parathyroid carcinoma (PCa) is a rare presentation of primary hyperparathyroidism (PHPT), accounting for less than 1 % of cases. Differentiating parathyroid cancer from adenoma is clinically challenging. Rubin et al (2008) et al. suggested that urinary hCG might be a marker of disease progression in PCa. In this study, we aimed to investigate whether the hCG+β kit from Roche Diagnostics could distinguish PCa patients from PHPT. Material and methods We studied a series of 8 patients suffering from advanced PCa, referred to the CHU de Liege. A control group of 20 PHPT patients was used as comparative. hCG+β kit on Cobas (Roche Diagnostics) uses 2 monoclonal antibodies that recognize holo-hCG, nicked hCG, β-core fragment and free β-subunit. Limits of hCG detection and quantification are <0.1 and <0.6 mUI/mL. In non pregnant and postmenopausal women and in men, hCG (p95) is <1 (5.3), <7 mUI/mL (8.3) and <2 (2.6) mUI/mL, respectively. Results. The 8 PCa patients (3 women) presented high serum hCG values at: 1.29, 3.46, 5.7, 24.2, 31.2, 34.1, 36.5 and 164 mUI/mL. Values of 1.29 and 3.46 were obtained in 2 postmenopausal women. The lowest value was presented by the only still alive patient. There was a significant correlation (r=0.786; ρ <0.05) between hCG and PTH and a borderline correlation (r=0.750; ρ =0.05) between hCG and calcium concentrations. All PHP patients presented undetectable hCG values. Conclusions These results suggest that serum hCG might have the potential to discriminate between parathyroid adenomas and carcinomas, with a sensibility of 75% (6/8) and a specificity of 100% (0/20). The only patient still alive presented the lowest hCG values. If hCG could be predictive of PCa survival needs to be studied in a larger series of patients. [less ▲]

BACKGROUND: We provide a clinical and analytical evaluation of the reformulated version of the Abbott Architect 25-hydroxyvitamin D assay. We compared this assay with three commercial automated immunoassays and against a VDSP-traceable liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) in six different populations. We also supplemented 40 healthy volunteers with either 600,000 IU of vitamin D2 or 100,000 of vitamin D3 to evaluate the performance of the immunoassays vs. the LC-MS/MS. METHODS: Precision and limit of quantification were assessed, 25(OH)D2 and C3-epimer recovery were calculated. Two hundred and forty samples obtained in healthy Caucasians and Africans, osteoporotic, hemodialyzed and intensive care patients and 3rd trimester pregnant women were analyzed by all methods. Correlation was studied using Passing-Bablok and Bland-Altman analysis. Concordance correlation coefficient (CCC) was calculated to evaluate agreement between immunoassays and LC-MS/MS. We verified if patients were homogeneously classified with the immunoassays when they took vitamin D2 or vitamin D3 after 1, 7 and 28 days. RESULTS: We observed excellent analytical features and showed a very good correlation to the LC-MS/MS results in the overall population. Compared to the other immunoassays, concordance of the new Abbott assay with the LC-MS/MS was at least similar, and often better in diseased populations. Althought the cross-reactivity with 25(OH)D2 was not of 100%, there was no significant difference in the classifications of the patients, either supplemented with D2 or D3 or after 7 or 28 days. CONCLUSIONS: This modified version of the Abbott Architect assay is clearly improved compared to the previous one and presents a better agreement with the LC-MS/MS. [less ▲]
