This study compared clinical features and protein expression profiles in differentiated thyroid tumours to identify protein markers with the potential for indicating malignancy status. Tissue microarrays were constructed using 119 thyroid tumour samples (45 papillary carcinomas, 26 follicular carcinomas, 48 adenomas). Generally, there was overexpression of proliferating cell nuclear antigen (PCNA), p53, matrix metalloproteinase (MMP)-7, Hector Battifora mesothelial-1 (HBME-1), MMP-2, pituitary tumour-transforming gene (PTTG) and human telomerase reverse transcriptase (hTERT) in malignant thyroid carcinomas, and overexpression of fragile histidine triad (FHIT), p16 and E-cadherin in thyroid adenomas. Multiple factor binary logistic regression analysis indicated that MMP-2, HBME-1, p16 and FHIT were independently related to differentiated thyroid tumours. Receiver–operating characteristics for these four factors showed HBME-1 as best for diagnostic accuracy. Sensitivity and specificity were enhanced using an HBME-1 and p16 cluster. HBME-1 expression was not significantly different for papillary and follicular carcinomas, whereas p16 expression was significantly specific.
