"[Compared to 85 'spontaneous' human thyroid tumors, the radiation-associated cases: (1) show a similar overall frequency of ras and gsp mutations (about 30% and 6% respectively); (2) present a similar frequency of mutation of the three ras genes without any predominance in adenomas and papillary carcinomas and (3) all Ki-ras mutations were found in papillary carcinomas (4/15). ras and gsp genes were never found mutated simultaneously, suggesting an alternative role for both oncogenes in the thyroid tumorigenic radiation-associated process.].
