Each year approximately 800 Australians are diagnosed with sarcoma, accounting for less than 1% of cancer diagnoses overall. A significant proportion of these sarcoma cases are in children and adolescents. ⋯ The Australasian Sarcoma Study Group (ASSG) was established in 2008 as a Cooperative Cancer Clinical Research Group and is now the peak body for sarcoma research in Australasia, providing a mechanism to drive and coordinate collaborative research, promote education and assist with advocating for sarcoma within the region. This paper describes the development of ASSG and examines the current state of play with regard to sarcoma research in Australasia.

The aim of this study was to determine prospectively the frequency of pathogenic chromosomal microdeletions and microduplications in a large group of referred patients with developmental delay (DD), intellectual disability (ID) or autism spectrum disorders (ASD) within a genetic diagnostic service. First tier testing was applied using a standardised oligo-array comparative genomic hybridization (CGH) platform, replacing conventional cytogenetic testing that would have been used in the past. ⋯ The greater diagnostic sensitivity arising from routine application of array CGH, compared with previously used conventional cytogenetics, outweighs the interpretative issues for the reporting laboratory and referring clinician arising from detection of CNVs of uncertain significance. Precise determination of any previously hidden molecular defect responsible for the patient's condition is translated to improved genetic counselling.
