Lactate dehydrogenase and body mass index are prognostic factors in patients with recurrent small cell lung cancer receiving amrubicin


Aims and background

Amrubicin monotherapy can be an effective treatment option for patients with recurrent small cell lung cancer (SCLC). We conducted this retrospective study to investigate the prognostic factors in patients with recurrent SCLC receiving amrubicin monotherapy.


The associations between survival and clinical data, including the performance status, body mass index (BMI), plasma lactate dehydrogenase (LDH) level, and plasma neuron-specific enolase level, were evaluated in patients with recurrent SCLC, and a subset analysis of patients with platinum-resistant disease was conducted.


In all, 37 patients were evaluated. The median survival from the date of initiation of amrubicin monotherapy was 9.1 months (95% confidence interval 4.7-12.0 months). Multivariate analysis using a Cox proportional hazard model identified the plasma LDH level (p = 0.049), BMI (p = 0.031), and platinum resistance (p = 0.032) as independent factors associated with survival. The same associations were also observed in the subset of patients with platinum-resistant disease.


Our findings suggest that the plasma LDH level and BMI may be useful prognostic factors in patients with SCLC receiving amrubicin monotherapy, including patients with platinum-resistant disease.
