Prognosis of thyroid cancer is very good as most cases are curable. Prognosis or outcome helps the patient to understand his or her chance of cure or recurrence (return) of disease. Understanding what the future holds allows the patient and the family to handle the disease, live with it better and decide on the important issues such as finance and life style changes.


Factors that affect the prognosis (chances of cure and risk for recurrence) of thyroid cancer include:

  • Type of the cancer (papillary, follicular, medullary, and anaplastic).
  • Site or location of the cancer.
  • Stage of cancer (the size of the tumor, extent of involvement of the organ, spread to other parts of the body).
  • Grade of tumor (how abnormal or malignant the cancer cells are and how quickly the cells grow and spread).
  • Patient factors such as age, general health, and response to treatment.

When discussing the prognosis, the five-year survival rate is considered. Survival rates of any type of cancer indicate the proportion of people with a certain type and stage of cancer who live for a specific period of time after diagnosis. The five-year survival rate indicates the percentage of people with the disease who are alive even five years after diagnosis (factors such as signs or symptoms of cancer, presence or absence of disease, or treatment are not considered).


Prognosis and stage:
Stage of  cancer is a major factor that influences the prognosis. Stage prognosis of thyroid cancers is also influenced by the type of cancer. The two commonest types of thyroid cancer are papillary thyroid cancer (78% of thyroid cancers) and follicular thyroid cancer (17% of thyroid cancers); they are easily curable. Prognosis is better in younger patients (younger than 40 years) as compared with older (more than 40 years of age).


Based on each stage, the five-year survival rate of the different types of thyroid cancers is as follows:


5-Year Relative Survival Rate of Papillary thyroid cancer

Stage

5-Year Relative Survival Rate

I

near 100%

II

near 100%

III

93%

IV

51%


5-Year Relative Survival Rate of Follicular thyroid cancer

Stage

5-Year Relative Survival Rate

I

near 100%

II

near 100%

III

71%

IV

50%



5-Year Relative Survival Rate of Medullary thyroid cancer

Stage

5-Year Relative Survival Rate

I

near 100%

II

98%

III

81%

IV

28%


Anaplastic carcinoma:
All cases of anaplastic (undifferentiated) carcinomas are considered to be stage IV. The 5-year relative survival rate for anaplastic (undifferentiated) carcinomas is around 7%.


When considered, the prognosis of most thyroid cancers is favourable when treated appropriately. It is one of the most curable cancers in humans. Remember that your doctor. while discussing the prognosis, predicts the possible course of the disease and therefore, cannot be absolutely correct about the outcome.
