Background: To survey the prevalence of potential drug-drug interactions (DDIs) between anticancer drugs and non-anticancer drugs and evaluate the risk factors associated with these drug-drug interactions in China.

Methods: All discharged patients in the Department of Oncology were collected from Jun to Dec in 2016 with the Hospital Information System of the Chinese people’s Liberation Army General Hospital. Drugs were screened for interactions by Micromedex solutions database. Descriptive statistics were generated and logistic regression was used to identify the associated factors.

Results: Among 6578 eligible patients, 1979 potential drug interactions were found in 1830 patients (27.82%). The most common drug-drug interaction was cisplatin and furosemide. Erlotinib was most likely to interact with various non-anticancer drugs. Most interactions were classified as pharmacodynamics (71.60%), major severity (97.02%) and were supported by fair documentation evidence (86.21%). In multivariate analysis, increasing number of medications, lung cancer and patients with stage IV had a higher risk for potential drug-drug interactions.

Conclusion: Potential drug-drug interactions between antineoplastic drugs and non-antineoplastic drugs occur frequently in cancer patients of Chinese hospitals. Doctors should fully consider potential risk associated with DDIs. Further research should be performed to evaluate real clinical significance of these drug-drug interactions.
