Interest of scintiscanning with indium 111 pentetreotide and technetium 99m sestamibi in the follow up of differentiated thyroid carcinomas. About 39 files

We have studied retrospectively, among 24 patients with a differentiated thyroid carcinoma and susceptible to have a recurrence or non remission, 39 scintiscanning files were realised, with technetium 99m-sestamibi or indium 111 pentetreotide. On the 19 scintiscanning practiced with indium 111 pentetreotide, it is observed 5 centres accumulating the tracer, 3 only correspond to local recurrences or distant metastases, each of ones being non iodine fixing. On the 20 scintiscanning made with technetium 99m sestamibi, it is found for two patients, 6 centres accumulating the tracer, corresponding to ganglions recurrences or distant metastases. The totality of these results do not appear very cheerful and are similar to literature data. (N.C.)
