Depending on source, the overall 5-year survival rate for<unk>  is 96 percent or 97 percent, with a 10-year survival rate of 93 percent. For a more specific prognosis for individual cases, there are at minimum 13 known scoring systems for prognosis; among the more often used are: * AGES - Age, Grade, Extent of disease, Size * AMES - Age, Metastasis, Extent of disease, Size * MACIS - Metastasis, Age at presentation, Completeness of surgical resection, Invasion (extrathyroidal), Size (this is a modification of the AGES system). It is probably the most reliable staging method available. Also known as the MAICS system. * TNM staging - Tumor, node, metastasis. Remarkable about the TNM staging for (differentiated) thyroid carcinoma is that the scoring is different according to age. MACIS The MACIS system of estimating the prognosis of<unk>  was developed by Clive S. Grant at the Mayo Clinic, and was based on careful evaluation of a large group of patients. It is probably the most reliable staging method available. It assigns scores to the main factors involved, and uses the sum of this score to calculate the prognosis: Factors Score Distant Metastasis: spread of the cancer to areas outside the neck Yes 3 No 0 Age at the time the tumor was discovered Less than 39 years 3.1 Over 40 years 0.08 x age Invasion into surrounding areas of the neck as seen by the naked eye Yes 1 No 0 Completeness of surgical resection (or removal) of the tumor Incomplete 1 Complete 0 Size of the tumor 0.3 x size in cm Sum of MACIS score 20 yr Survival 8.0 24% Most patients fall into the low-risk category (MACIS score less than 6.0) and are cured of the cancer at the time of surgery. Children with multiple lung metastases and/or a miliary aspect still have an excellent long-term prognosis if given adequate treatment. Stage Based on overall cancer staging into stages I to IV,<unk>  has a 5-year survival rate of 100 percent for stages I and II, 93 percent for stage III and 51 percent for stage IV.
