Of those, one was the previously discussed TRG1 case with GNAS mutation (EOC14), one patient had R1 resection of a T4 abscessed tumor, developed rapidly progressive lymphangitic carcinomatosis and died 2 months after surgery (EOC18); one patient had R0 resection for a TRG4 ypT4N0, LnVi(−), Pni(−), G2 tumor and presented liver metastases 12 months after surgery (EOC11). Here, GNAS is linked to neoplasm.
