Abstract

Sarcopenia and adipopenia have prognostic significance in cancer. Analysis of a single abdominal computed tomography (CT) section at the third lumbar vertebra has been widely adopted for this purpose. The approach using a single section at the first lumbar vertebra level (L1) may extend clinical viability. We evaluated the prognostic value of sarcopenia and adipopenia assessed using a CT section at L1 in acute myeloid leukemia (AML). Data from 96 patients with available imaging were retrospectively reviewed. Patients with sarcopenia (37.5%) had significantly worse overall survival (OS) (median 17.8 months vs. not reached, p = 0.038) and treatment-related mortality (TRM) (22.2% vs. 3.0%, p = 0.0019) than those without. Subcutaneous adipopenia (51.0%) was significantly associated with inferior OS (median 17.9 months vs. not reached, p = 0.0011), progression-free survival (PFS) (median 6.2 months vs. not reached, p = 0.004), and TRM (16.3% vs. 4%, p = 0.024). Visceral adipopenia (30.2%) was associated with poor OS (12.7 vs. 31.7 months, p = 0.0055) and PFS (3.7 vs. 31.7 months, p = 0.003). Multivariable analyses found sarcopenia, subcutaneous adipopenia and visceral adipopenia were significant negative prognostic factors for OS. Sarcopenia and adipopenia assessed using a single CT section at the L1 level are useful in predicting the prognosis of AML.
