ERCC1 and Decreased total leukocyte count: Erčulj et al. (2012) reported that patients carrying A allele had a lower risk of grade 2-4 leukopenia in 94 malignant mesothelioma patients (OR = 0.18; 95% CI: 0.04–0.86; p = 0.032). No association has been established between ERCC1 rs3212961 (17677G>T) and the development of hematologic toxicity (Marsh et al., 2007; Lambrechts et al., 2015; Song et al., 2017).
