Abstract
Aim. To evaluate the frequency and clinical significance of drug-drug interactions (DDI) in patients receiving drug antitumor therapy using the Drugs® and Medscape® DDI calculators.
Materials and methods. The study included 282 patients with a mean age of 65 years (36–84) who received FOLFOX chemotherapy, of whom 151 (53%) were males and 131 (47%) were females. At the start of the first course of chemotherapy, 214 (75%) patients were receiving concomitant therapy on a regular basis.
Results. The odds of severe toxicity in patients receiving concomitant therapy were 2.720 times higher [95% confidence interval (CI) 1.025–7.218; p=0.038]. Patients with strong DDI were statistically significantly more likely to develop mucositis after the first course of drug antitumor therapy: 14 (38.9%) vs 36 (20.2%) according to Drugs®, p=0.041; 22 (33.3%) vs 28 (18.9%) according to Medscape®; p=0.036. Similar results were obtained in a subgroup of patients at risk of QT prolongation according to Drugs® – 10 (52.6%) vs 40 (20.5%); p<0.001. Patients taking calcium channel blockers were statistically significantly more likely to develop dose-limiting toxicity: 18 (40.9%) vs 52 (21.8%). The odds of dose-limiting toxicity were 2.476 times higher: 95% CI 1.261–4.864; p=0.007.
Conclusion. The incidence of DDI in patients with gastrointestinal tumors receiving FOLFOX best supportive therapy can be as high as 90.2%, with one in three DDI classified as serious. Drugs® and Medscape® DDI services cover only 80% of concomitant medications and are not adapted to oncology, necessitating the development of more versatile approaches.
