Incidence of differentiated thyroid cancer has increased in the last two decades. This type of cancer is now being diagnosed at an earlier stage. Treatment strategy has been modified. Aims: The goals of this study were to analyze the outcome of differentiated thyroid cancer after initial treatment (surgery and radioiodine ablation) in patients evaluated and followed up in a single centre between l999 and 2009, to compare these results with others as well as to monitor the adoption of international recommendation. 107 patients having T1-T2 differentiated thyroid cancer were studied. Mean follow-up time was 63 months. Results: After surgery patients were prepared using thyroid hormone withdrawal or recombinant human thyrotropin, then 1.1-3.7 GBq 131-iodine was administered. First year evaluation consisted of ultrasound as well as serum thyrotropin and thyroglobulin (plus thyroglobulin antibody) determinations. Ablation success rate was 83% and the five year survival was 100%. There was not any cancer specific death. Conclusion: In the future somewhat more radical surgery and less remnant ablation is needed with unified follow-up protocol. Orv. Hetil., 2011, 152, 1731–1738.

Recent studies have provided new information regarding the optimal surveillance protocols for low-risk patients with differentiated thyroid cancer (DTC). This article summarizes the main issues brought out in a consensus conference of thyroid cancer specialists who analyzed and discussed this new data. There is growing recognition of the value of serum thyroglobulin (Tg) as part of routine surveillance. An undetectable serum Tg measured during thyroid hormone suppression of TSH (THST) is often misleading. Eight studies show that 21% of 784 patients who had no clinical evidence of tumor with baseline serum Tg levels usually below 1 μg/liter during THST had, in response to recombinant human TSH (rhTSH), a rise in serum Tg to more than 2 μg/liter. When this happened, 36% of the patients were found to have metastases (36% at distant sites) that were identified in 91% by an rhTSH-stimulated Tg above 2 μg/liter. Diagnostic whole body scanning, after either rhTSH or thyroid hormone withdrawal, identified only 19% of the cases of metastases. Ten studies comprising 1599 patients demonstrate that a TSH-stimulated Tg test using a Tg cutoff of 2 μg/liter (either after thyroid hormone withdrawal or 72 h after rhTSH) is sufficiently sensitive to be used as the principal test in the follow-up management of low-risk patients with DTC and that the routine use of diagnostic whole body scanning in follow-up should be discouraged. On the basis of the foregoing, we propose a surveillance guideline using TSH-stimulated Tg levels for patients who have undergone total or near-total thyroidectomy and 131I ablation for DTC and have no clinical evidence of residual tumor with a serum Tg below 1 μg/liter during THST.

IntroductionAfter initial treatment, differentiated thyroid cancer (DTC) patients are stratified as low and high risk based on clinical/pathological features. Recently, a risk stratification based on additional clinical data accumulated during follow-up has been proposed.ObjectiveTo evaluate the predictive value of delayed risk stratification (DRS) obtained at the time of the first diagnostic control (8–12 months after initial treatment).MethodsWe reviewed 512 patients with DTC whose risk assessment was initially defined according to the American (ATA) and European Thyroid Association (ETA) guidelines. At the time of the first control, 8–12 months after initial treatment, patients were re-stratified according to their clinical status: DRS.ResultsUsing DRS, about 50% of ATA/ETA intermediate/high-risk patients moved to DRS low-risk category, while about 10% of ATA/ETA low-risk patients moved to DRS high-risk category. The ability of the DRS to predict the final outcome was superior to that of ATA and ETA. Positive and negative predictive values for both ATA (39.2 and 90.6% respectively) and ETA (38.4 and 91.3% respectively) were significantly lower than that observed with the DRS (72.8 and 96.3% respectively,P<0.05). The observed variance in predicting final outcome was 25.4% for ATA, 19.1% for ETA, and 62.1% for DRS.ConclusionsDelaying the risk stratification of DTC patients at a time when the response to surgery and radioiodine ablation is evident allows to better define individual risk and to better modulate the subsequent follow-up.

The use of recombinant human thyrotropin (rhTSH) testing in the diagnosis and therapy of differentiated thyroid cancer (DTC) has been adopted over the last two decades as an alternative to the classical thyroid hormone withdrawal avoiding the threat of hypothyroidism. Serum thyroglobulin (Tg) measurement is crucial for monitoring DTC patients over time. Until about a decade ago, optimal sensitivity of Tg assays for the detection of smaller disease foci required Tg measurement after thyrotropin (TSH) stimulation, carried out following thyroid hormone withdrawal or rhTSH administration. In very recent years, significant improvements in assay technology have resulted in highly sensitive Tg (hsTg) assays, sufficiently sensitive to obviate the need for rhTSH stimulation in most DTC patients. The aim of this paper is to review and discuss, via a ‘pros and cons’ approach, the current clinical role of rhTSH to stimulate radioiodine (RAI) uptake for treatment and/or imaging purposes and to increase the clinical sensitivity of Tg measurement for monitoring DTC patients when high-sensitive Tg assays are available.

Recombinant human TSH (rhTSH) is an effective and safe alternative to thyroid hormone withdrawal during the post-surgical follow-up of papillary and follicular thyroid cancer. Its clinical efficiency for the detection of persistent and recurrent disease is similar to that of thyroid hormone withdrawal. The main purpose for its use is to avoid hypothyroidism.
