Prognosis
Depending on source, the overall 5-year survival rate for papillary thyroid cancer 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 papillary thyroid cancer 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:

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.
Through examinations in families it was found that there is a family connection to the occurrences, which leads to the conclusion that there is a genetic predisposition for it; for example, patients with folliculitis decalvans could have a hereditary different opening of the hair follicle that could facilitate the lodging of the bacteria. Immunologically, another possibility is that especially strong intercellular fixation protein ICAM-1 contributes to inflammation with its strong effect of attracting white blood cells such as granulocytes and lymphocytes.

Management
Some sufferers have found that a daily intake of MSM helps relieve the inflammation and scarring that comes with chronic Folliculitis decalvans. Epidemiology
This disorder was first described by Charles-Eugène Quinquaud in 1888. He isolated bacteria from the hair follicles of affected patients and introduced them in rats, mice and rabbits, with no result. In 1905 it was then differentiated from other scarring alopecias and the name Folliculitis decalvans, that remains current, was introduced. About 11% of the occurrences of scarring alopecias are of this type. Men are more commonly affected than women and its appearance is usually between the late teens and middle adult years. According to studies in the United States, African Americans are more frequently affected than White Americans. See also
