87 Epidemiology Study of Elderly Patients with Acute Myeloid Leukaemia at a Haematological Tertiary Referral Centre

Acute Myeloid Leukemia (AML) is a rare disease with a high incidence in the elderly. Our aim is to report the incidence of elderly patients with AML at a haematological tertiary referral centre. Method We have collected data from 2007 till 2017 from the main Malaysian haematological tertiary referral centre involving all the 1225 AML patients. Out of those, 182 elderly patients aged 65 and above with AML were examined. The patients had at least 2 years follow-up. Results The elderly represented 14.9% of the 1225 patients who presented with acute myeloid leukemia to the centre. There were 182 elderly patients with AML which were subdivided to the unspecified AML of 154 patients, 1 patient with M1, 4 patients with M2, 6 patients with M3, 5 patients with M4, 8 patients with M5, 2 patients with M6 and 2 patients with M7. There were 109 males and 73 females. The majority of the patients were Chinese (n=85) representing 46.7% of the patients, followed by the Malay (n=76), Indian (n=19) and lastly others (n=2). The average age at diagnosis was 71 years. There were 136 deaths and the mortality rate was 74.7%. The average age of the patients who had passed away (n=136) was 71.4 years. The average age of the patients who are still living (n=42) was 76.5 years. Conclusion The incidence of elderly AML is increasing. The younger patients with AML are known to have better survival rate in comparison to the elderly. More research is needed to explore the reasons for the higher mortality in the elderly and the ways to improve the outcome of this elderly population as our lifespan increases and Malaysia heads towards an ageing nation.
