Background: Changes in the incidence of bleomycin pulmonary toxicity (BPT) as a result of adding colony-stimulating factors (CSF) to bleomycin regimens has been investigated in numerous studies. We performed a systematic review and meta-analysis to assess the outcomes of these studies.
Methods: A systematic search was performed using Pubmed, Scopus, Web of Science, and Embase on April 2021. Studies evaluating the incidence of BPT in patients receiving bleomycin with and without CSF were included. In addition, meta-analysis was performed by pooling odds ratios using R.
Results: Out of 340 obtained records, our qualitative and quantitative analysis included 3234 and 1956 patients from 22 and 14 studies, respectively. The quantitative synthesis showed that addition of CSF significantly increased the risk of BPT incidence (OR = 1.82, 95 % CI: 1.37-2.40, p < 0.0001; I2 = 10.7 %). Subgroup analysis did not show any association between continent, bleomycin dose, cancer type, type of study, and pulmonary function test with BPT incidence.
Conclusion: This systematic review and meta-analysis showed that co-administration of CSF with bleomycin increases the incidence of BPT. The physicians need to consider this finding while deciding the best strategy for this cohort of patients.
