Parathyroid Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for Parathyroid Cancer

Because of the low incidence of parathyroid carcinoma, an American Joint Committee on Cancer staging system has not yet been formulated and thus is not applicable to this malignancy. In addition, neither tumor size nor lymph node status appear to be important prognostic markers for this malignancy.[1]

Patients are considered to have either localized or metastatic disease.[2,3]

Who is at Risk?

Endometrial cancer is a disease that primarily affects postmenopausal women at an average age of 60 years at diagnosis. Risk factors include postmenopausal estrogen therapy, obesity, a high-fat diet, reproductive factors like nulliparity, early menarche and late menopause, polycystic ovarian syndrome, and tamoxifen use. Women with hereditary nonpolyposis colorectal cancer syndrome have a markedly increased risk of endometrial cancer compared with women in the general population.

Localized Parathyroid Cancer

Localized parathyroid cancer is disease that involves the parathyroid gland with or without invasion of adjacent tissues.

Metastatic Parathyroid Cancer

Metastatic parathyroid cancer is disease that spreads beyond the tissues adjacent to the involved parathyroid gland(s). Parathyroid carcinoma most frequently metastasizes to regional lymph nodes and lungs, and it may involve other distant sites, such as liver, bone, pleura, pericardium, and pancreas.[4]
