Validation of a screening tool in geriatric oncology: The Oncodage project

Abstract

Assess the utility of the G8 screening tool and CGA for older adults with head and neck cancer.Patients 65 years or older with a primary malignancy of the head and neck region were presented at the multidisciplinary team (MDT) meeting. The Geriatric 8 (G8) questionnaire was administered prior. Clinicians, blinded to the G8 result, made a recommendation on appropriate treatment, including potential referral for CGA. Patients considered vulnerable (G8 score ≤ 14) were also to be referred for CGA. Treatment outcomes were recorded.Over 6 months, 35 patients were recruited, median age 74 (range 65–93). Seventeen (49%) patients were assessed as vulnerable by the G8 score, including 7 (20%) whom the MDT referred for CGA. Seven with G8 scores ≤ 14 did not receive a CGA. Thirty (85.7%) underwent curative intent treatment, including 6 of 7 who had CGA. Of 10 vulnerable patients who did not have CGA, 70% received curative-intent treatment. Mean length of post-operative stay was 12.2 vs. 6.5 days in patients deemed vulnerable or fit by G8 scores, respectively (p = 0.46); completion rate of radical radiotherapy was 75% vs. 100% in each group, respectively (p = 0.13). Mean post-operative length of stay in vulnerable patients who underwent a CGA was 6.2 days vs. 17.3 days in those who were not referred (p = 0.79).The G8 tool identified twice the number of patients as vulnerable compared to the MDT. There was a trend towards longer postoperative stay and lower radiotherapy completion rates in patients deemed vulnerable by G8 scores.
