Abstract

BACKGROUND/AIM: High-dose chemotherapy is frequently administered to patients with hematologic malignancies, thereby causing severe adverse drug reactions (ADRs) at a relatively high frequency. To precisely monitor ADRs, we developed a medication instruction sheet (MIS) for patients who received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) combination therapy for non-Hodgkin's lymphoma (NHL). Herein, we evaluated the usefulness of the MIS for managing ADRs in patients who received R-CHOP therapy.

PATIENTS AND METHODS: We included patients aged ≥20 years who received R-CHOP therapy as first-line treatment for NHL at the Department of Hematology, Kyushu University Hospital, between August 2014 and December 2018. Medical professionals evaluated the possible occurrence of ADRs according to the present MIS and ADRs were graded according to the Common Toxicity Criteria, version 4.0 (National Cancer Institute, Bethesda, MD, USA). Finally, the accuracy of the MIS in predicting the occurrence of ADRs of different grades and during definite periods was evaluated.

RESULTS: Seventy-five patients with NHL were included in the present study. Overall, 359 ADR events were monitored, which were predicted ADR items listed in the MIS. Among these, 254 (71%) events occurred during the same period as those listed in the MIS. The onset timing of any grade of an infusion reaction and peripheral neuropathy precisely matched those listed in the MIS. However, the accuracy of the MIS was reduced in patients with thrombocytopenia (42%).

CONCLUSION: The present MIS could be useful for monitoring ADRs in patients with cancer undergoing R-CHOP therapy.
