Furthermore, the R833C mutation is capable of sustaining the transformed phenotype in vivo but does not confer upon the transformed cells the ability to degrade the basement membrane in a manner analogous to metastasis.
Individuals with the C634R mutation presented significantly more distant metastases at diagnosis than subjects with the C634Y or C634W mutations (54.5% vs. 19.4% vs. 14.3%, respectively, P = 0.03).
The Kaplan-Meier estimate of cumulative lymph node and distant metastases rates showed that these events occurred earlier in patients harbouring the C634R mutation (P<0.001).
Individuals with the C634R mutation presented significantly more distant metastasesat diagnosis than subjects with the C634Y or C634W mutations (54.5% vs. 19.4% vs. 14.3%, respectively, P = 0.03).
Moreover, we strongly suggest prophylactic thyroidectomy should be performed before age 5 in carriers with p.C618S to prevent the occurrence and metastasis of MTC.
