[Expressions of wildtype-RET and RET/PTC rearrangements in sporadic adult papillary thyroid carcinoma and their clinicopathologic correlation]..     ///    "(3) Fourteen PTCs (21.2%) expressed RET/PTC, including five cases expressing RET/PTC1 and nine cases expressing RET/PTC3. "    ///    Six cases (9%) expressed both RET/PTC and WT-RET.     ///    (4) Statistic analysis did not show any correlation between the expression of WT-RET or RET/PTC and clinicopathologic parameters.     ///    The expression of RET/PTC was specific to PTC.     ///     To evaluate the expressions of wildtype-RET (WT-RET) and RET/PTC in sporadic adult papillary thyroid carcinoma and to investigate their clinicopathologic correlation.
