Features Of Familiality In A Cohort Of Patients (Pts) With Sarcoma
JOURNAL OF CLINICAL ONCOLOGY(2012)
Abstract
1547 Background: Sarcomas occur in a number of cancer predisposition syndromes, yet genetic evaluation is rarely recommended for sarcoma pts. We broadly reviewed the family cancer histories of unselected pts in a tertiary center sarcoma clinic to explore the potential relevance of genetic assessment. Methods: Between 2005 and 2008, 397 pts (median age 52 years) with documented sarcoma who consented to research use of medical records and tissues also completed a family history questionnaire. Patient and family histories were reviewed for features suggesting hereditary risk (e.g. early age at diagnosis or familial clustering of certain associated diagnoses). Results: A family history of malignancy was noted in 301 of 397 pts (76%). Seventy-six pts (19%) were diagnosed with 99 additional malignancies, most frequently breast cancer (n=23), prostate cancer (12), melanoma (12), thyroid cancer (6) or a second sarcoma (10). Sarcoma was diagnosed prior to or synchronously (within 6 months) with another malignancy ...
