Even though RET/PTC is a specific genetic event in the carcinomas, our results suggested the possibility of RET/PTC as "passenger" abnormalities rather than "driver" oncogenic mutation during thyroid cancer progression, warranting further studies on mechanisms and implication of RET gene instability.

The molecular pathology of thyroid cancer is now better understood because of our ability to identify RET/PTC rearrangements and BRAF mutations in the aetiopathogenesis of the large majority of PTCs and the high prevalence of RAS mutations and PAX8/PPARgamma rearrangements in follicular patterned carcinomas (FTCs and follicular variant of PTCs).

Present data suggest that: (1) the incidence of FAP-associated thyroid cancer probably has been underestimated in the past; (2) intensive screening could detect a larger than expected number of thyroid carcinomas; (3) systematic screening is recommended in patients with ocular patches and genetic mutation in exon 15; (4) Hashimoto-like findings do not exclude carcinoma but are a frequent accompanying finding; (5) despite frequent multicentricity and early lymph node involvement, FAP-associated thyroid tumors seem to have an excellent prognosis, in particular those showing ret-PTC activation.
