Adherence and safety of regorafenib for patients with metastatic colorectal cancer: observational real-life study

Aim: In this prospective multicenter real-life observational cohort study, we investigated the acceptance, adherence and safety of regorafenib, in the treatment of metastatic colorectal cancer patients. Patients & methods: A total of 136 patients were recruited at six oncological hospital sites in southern Italy. The adherence to the treatment was measured with patient-completed medication diaries, physician interviews and pill counts. Results: We found a statistically significant improvement of therapy adhesion by the acceptance questionnaire. The Eastern Cooperative Oncology Group performance status, the level of acceptance, the educational level and the concomitant usage of oral medications influenced the adherence to the treatment. Conclusion: Patients' level of education, concomitant other oral medications and patients' general clinical condition may influence the adherence to regorafenib.
