AbstractTo analyze the incidence and nongenetic risk factors of irinotecan-induced severe neutropenia in the hospital, and provide additional reference and help for clinical treatment. A retrospective analysis of patients who received irinotecan based chemotherapy from May 2014 to May 2019 in Renmin Hospital of Wuhan University was conducted. Univariate analysis and binary logistic regression analysis with the forward stepwise method were used to assess the risk factors associated with severe neutropenia induced by irinotecan. Of the 1312 patients treated with irinotecan-based regmines, only 612 patients met the inclusion criteria, and 32 patients developed irinotecan-induced severe neutropenia. In the univariate analysis, variables associated with severe neutropenia were tumor type, tumor stage, and therapeutic regimen. In the multivariate analysis, irinotecan plus lobaplatin, lung cancer or ovarian cancer, tumor stage T2, T3, and T4, were identified as risk factors that contributed independently to irinotecan-induced severe neutropenia (P < .05), respectively. The results showed that the incidence of irinotecan-induced severe neutropenia was 5.23% in the hospital. The risk factors included tumor type (lung cancer or ovarian cancer), tumor stage (T2, T3, and T4) and therapeutic regimen (irinotecan plus lobaplatin). Therefore, for patients with these risk factors, it might be advisable to actively consider optimum management to reduce the occurrence of irinotecan-induced severe neutropenia.Copyright © 2023 the Author(s).
