Research
In the past, randomised trials were very rare, and robust evi-
dence for or against a treatment were not frequently available
for early and advanced thyroid cancers. Although this is slowly
improving, clinicians still have to deal with management of
uncertainty or clinical equipoise frequently. In such cases partici-
pation in clinical trials in pursuit of level 1 evidence is impor-
tant.
i Patients should be informed about and given the opportunity
to consider participation in ongoing randomized clinical trials
in cases where there is genuine clinical equipoise or lack of
level 1 evidence (4, D)
