All eight domains were predictive for at least one of the investigated outcomes but the results were quite variable across studies .
Physical function and nutritional status were the domains most often associated with mortality and systemic treatment-related outcomes , and the domain physical function was most often associated with postoperative complications .
Overall , this review demonstrates that the GA should minimally consist of physical function and nutritional status , when the aim is to predict patients -related outcomes of older patients with cancer , although the results are quite heterogeneous .
BACKGROUND A geriatric assessment ( GA ) is increasingly used to help guide treatment decisions in older patients with cancer .
However , there is no consensus regarding which domains should be included in the GA .
In addition , the field of geriatric oncology moves very fast and as a result many new studies have been published since the last review in 2015 .
Therefore , the objective of this systematic review is to evaluate which domains of the GA could predict patient-related treatment outcomes of older patients with cancer and thereby should be included in a GA .
Comprehensive geriatric assessment of risk factors associated with adverse outcomes and resource utilization in cancer patients undergoing abdominal surgery.
BACKGROUND The purpose of this prospect i ve study was to identify risk factors for adverse outcomes or increased re source utilization after  abdominal cancer surgery in geriatric patients . METHODS Baseline clinical and geriatric assessment variables  including functional status , nutritional status , comorbidity index , mental status , depression scale score , fatigue inventory scale , and polypharmacy scale were prospect ively recorded for patients age ≥65 undergoing intra-abdominal oncologic surgery .  Outcome variables included morbidity , mortality , discharge to nursing facility , prolonged hospital stay , and readmission . RESULTS Of 111 patients , surgery type was colorectal in 40 % , hepatopancreatobiliary in 30 % , and gastric/duodenal in 14 % . Variables associated with discharge to a nursing facility on multivariate analysis included weight loss ≥10 % ( OR 6.52 [ 95 % CI : 1.43 - 29.76 ] , P = 0.02 ) , ASA score ≥2 ( OR 5.08 [ 1.13 - 22.77 ] , P = 0.03 ) , and ECOG score ≥2 ( OR 4.51 [ 1.03 - 19.71 ] , P = 0.04 ) . Variables independently associated with prolonged hospital stay included weight loss ≥10 % ( OR 4.03 [ 1.13 - 14.43 ] , P = 0.03 ) , the presence of polypharmacy ( OR 2.45 [ 1.09 - 5.48 ] , P = 0.03 ) , and distant disease ( OR 0.37 [ 0.15 - 0.91 ] , P = 0.03 ) . No variables were associated with morbidity or readmission . CONCLUSIONS Pre-operative clinical and geriatric assessment tools can help predict the need for discharge to a nursing facility or increased length of stay . Future studies will be required to identify patients suitable for interventions to decrease hospital and post-discharge re source utilization
