Prevalence of RET/PTC expression in papillary thyroid carcinoma and its correlation with prognostic factors in a north Indian population..     ///    "However, uniform techniques of detection and large international collaborative studies could clear the uncertainties regarding the prognostic importance of RET/PTC.. "    ///    "However, the exact clinical significance of RET/PTC positive histiocytes remained unexplained. "    ///    The aim of this study was to recognize the prevalence of RET/PTC expression in PTC from the endemically iodine-deficient region in Northern India and to correlate the expression with the clinicopathologic prognostic factors.     ///    Prevalence of RET/PTC in our study was consistent with the reported prevalence from other geographic areas.
