DTC-recurrence and patient survival.  Statistically there was no significant difference in numbers of suspected DTC recurrences in (a) low/very low and (b) high-risk DTC categories as well (Log Rank P = 0.317; Log Rank P = 0.761, resp.). (c)  Histological evidence (lymph node and bone metastasis) for DTC recurrence was found only in one case. (d) There was no difference in patient survival (Log Rank P = 0.299). One patient of the hypothyroidism group died due to natural cause. Prior to death this patient had neither a suspected nor histological proven DTC recurrence.
