[edit] Prognosis For Thyroid Cancer
The long-term survival is usually much better in a thyroid cancer that is found at stage I or II. Stage III and IV have a worse outcome as often distant metastases are either there (stage IV) or are developing soon(stage III) in a high percentage. However, with thyroid cancer, as explained above, an important prognostic factor is the histology. To illustrate this, the 10-year survival rates are given here for four different histological types after early diagnosis and thyroid cancer treatment.
| 10-year survivals in four common thyroid cancers | |
| Cell types found by pathologist |
10-year cancer survival (%) |
| Papillary thyroid cancer | 85 |
| Follicular thyroid cancer | 65 |
| Medullary thyroid cancer | 80* |
| Anaplastic thyroid cancer | 0 |
*Note that in the past prior to calcitonin level screening this survival rate typically was 50%
The anaplastic thyroid cancer, even when found early and treated with chemotherapy, has an overall cancer survival rate of just over 2 years.
