Results From December 2019 to January 2021 G8q was submitted to 135 patients. Fifty-eight patients (43%) were baseline identified as frail (G8 score range 3-14). Of the 58, 28 patients (48.3%) agreed to undergo a multidimensional geriatric assessment, while 30 (51.7%) could not be evaluated due to COVID-19 dispositions or their refusal. Following the evaluation, frail patients were classified as fit (12 patients) or vulnerable (16 patients) according to score obtained in different domains (Table 1). Both fit and vulnerable patients were carefully monitored during RT according to geriatric prescriptions. The 58 frail patients, except 4 that refused RT before starting, completed treatment without acute toxicity > grade 2 (RTOG). The G8q repeated at the end of RT resulted worse in 12 patients, while 7 patients showed a benefit from RT, reporting a G8 score improvement. Considering all patients, 9 no-frail patients reported a worse G8 score at the end of RT and 2 patients an improvement. Still now, only 6 vulnerable patients repeat the 6-month assessment and the G8 score resulted lower in all the patients (less 1-5 points).
