The Acute Promyelocytic Leukaemia Asian Consortium (APL-AC) Project

There is currently lack of collaborative data on the epidemiology, clinicopathologic features and treatment outcome of newly diagnosed and relapsed APL in Asia. In addition, there is lack of data comparing oral- As2O3-based regimens with other treatment approaches, including intravenous As2O3,in the frontline or relapsed setting. With the long-term data of oral-As2O3 based regimen for APL available from Hong Kong, retrospective and prospective comparison with other treatment approaches in other Asian countries will generate important information to pave the way for widespread application of oral-As2O3 outside Hong Kong.
