Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options

Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…

Bone metastases in soft tissue sarcoma patients: A survey of natural, prognostic value, and treatment.

10063 Background: Given the limited data currently available, we surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods: This retrospective, multicenter, observational study evaluated data from 135 patients with STS metastatic to the bone who presented between 2001 and 2011. For all patients, we recorded the primary tumor histological subtype, bone metastases characteristics (onset, site), type of treatment received (surgery, radiotherapy, zoledronic acid), type and frequency of skeletal related events (SRE) and disease outcome. Results: The most represented histological subtypes among the enrolled patients were leiomyosarcoma (27%), angi…

Analysis of Heritability and Shared Heritability Based on Genome-Wide Association Studies for Thirteen Cancer Types

BACKGROUND: Studies of related individuals have consistently demonstrated notable familial aggregation of cancer. We aim to estimate the heritability and genetic correlation attributable to the additive effects of common single-nucleotide polymorphisms (SNPs) for cancer at 13 anatomical sites.METHODS: Between 2007 and 2014, the US National Cancer Institute has generated data from genome-wide association studies (GWAS) for 49 492 cancer case patients and 34 131 control patients. We apply novel mixed model methodology (GCTA) to this GWAS data to estimate the heritability of individual cancers, as well as the proportion of heritability attributable to cigarette smoking in smoking-related cance…
