Prognosis of body mass index and chemotherapy dose capping in acute myeloid leukaemia.
Body Mass Index (BMI) prognosis in acute myeloid leukaemia (AML) is unknown. Capping chemotherapy dose at 2m(2) of body surface area (BSA) is used without any rationale. We assessed whether both of them could be correlated with outcome in 233 AML patients. Thirty three percent were overweight, 10% obese and BSA over 2m(2) was observed in 15%. BMI and BSA>2m(2) were not associated with OS (p=0.16; p=0.39), nor with DFS (p=0.18; p=0.42), nor with CR. OS-associated factors were age (p<0.001), cytogenetic (p=0.002), FLT3-ITD (p=0.01). BMI and chemotherapy dose capping are not pejorative factors on intensively treated AML patients.
