Elderly cancer patients with normal complete blood cell counts (CBCs) during the first course of (some types of) chemotherapy might be unlikely to experience grade 4 neutropenia during subsequent cycles. In this case, further weekly CBCs might be avoided. We used data of 223 cancer patients aged 70+ who were included in the CRASH (Chemotherapy Risk Assessment Score for High-age patients) trial between 2003 and 2007 in 7 cancer practices in the US. First cycle CBC values were compared to subsequent cycles. MAX2-score was used as a measure for toxicity of the chemotherapy regimen. Sixty-two patients (28%) experienced grade 4 neutropenia during subsequent cycles. Among patients who received chemotherapy with a MAX2-score lower than 0.20, only 4.6% of those without neutropenia during the first cycle experienced grade 4 neutropenia during subsequent cycles. Weekly CBC might be avoided in these patients receiving chemotherapy. Future prospective studies should confirm these results.
