Comprehensive Geriatric Assessment (CGA) is a multidisciplinary evaluation tool designed to determine an elderly persons’ functional status, affect, cognition, nutritional status, comorbidities and social support in order to tailor their therapy. However it is a time-consuming tool to use in clinical practice. G8 screening tool which comprises only 8 questions is a quick and simple tool to screen elderly cancer patients and may select elderly patients who might then benefit from assessment with a CGA. This study objective was to address the association between different components of the CGA and the G8 screening tool in order to validate the applicability of the G8 in an Asian tertiary cancer centre.


From June 2015 to May 2016, cancer patients who attended the outpatient oncology clinics at the National Cancer Centre Singapore aged 70 years old and above were approached to be assessed. All the patients who gave consent to participate were evaluated using the G8 and the CGA. Those with a G8 score of less than 15 and those with CGA deficit in at least one component were defined as abnormal. Patient demographics and clinical characteristics were evaluated. Fisher’s transformation of Spearman’s rho was used to assess the linear association between the G8 and all the CGA components assessed.


184 patients with a median age of 76 years were enrolled. The study cohort had 56% males and was predominantly of Chinese ethnicity (87%). All 184(100%) patients had CGA done on them. 176 patients (95.7%) completed G8 and 80.1% of them had an abnormal score (


In the Asian population the G8 screening tool was not a good predictor of deficits of patient’s mood (GDS) and caregiver burden assessment. These 2 components of the CGA still need a thorough assessment even if the G8 score is normal.
