Parathyroid Cancer Versus Atypical Parathyroid Neoplasm; Investigating Their Clinical Characteristics and Biological Behavior

Parathyroid Cancer Versus Atypical Parathyroid Neoplasm; Investigating Their Clinical Characteristics and Biological Behavior

Objectives:

1. Identify the clinical characteristics of parathyroid (PTH) cancer and PTH atypical neoplasms
2. Investigate if PTH carcinoma and atypical neoplasm present a biological behaviour and have a different impact on the health of the patients

Data between the years of 1/1/2002 and 12/31/2013 will be analyzed. The medical records of all adult patients that had a parathyroidectomy for primary PHPT in MD Anderson Cancer Center will be screened in order to identify patients that had a histopathological diagnosis of parathyroid carcinoma or atypical parathyroid neoplasm.

Inclusion Criteria:

• All patients from MDACC diagnosed with PHPT that have a histopathological diagnosis of PTH carcinoma or atypical parathyroid neoplasm between the years 1/1/2002 and 12/31/2013

Exclusion Criteria:

• Pediatric patients
• Cases with incomplete records
• Patients where the follow-up will be less than six months
