Expert consensus panel guidelines on geriatric assessment in oncology.

Despite consensus guidelines on best practice in the care of older patients with cancer, geriatric assessment (GA) has yet to be optimally integrated into the field of oncology in most countries. There is a relative lack of consensus in the published literature as to the best approach to take, and there is a degree of uncertainty as to how integration of geriatric medicine principles might optimally predict patient outcomes. The aim of the current study was to obtain consensus on GA in oncology to inform the implementation of a geriatric oncology programme. A four-round Delphi process was employed. The Delphi method is a structured group facilitation process, using multiple iterations to gain consensus on a given topic. Consensus was reached on the optimal assessment method and interventions required for the commonly employed domains of GA. Other aspects of GA, such as screening methods and age cut-off for assessment, represented a higher degree of disagreement. The expert panel employed in this study clearly identified the criteria that should be included in a clinical geriatric oncology programme. In the absence of evidence-based guidelines, this may prove useful in the care of older cancer patients.
