Pharmacovigilance started about 170 years ago, although it was not yet named as such at that time. It is structured activity in the professional health field, with important social and commercial implications aimed at monitoring the risk/benefit ratio of drugs, improving patient’s safety and the quality of life. In this commentary we report the milestones of pharmacovigilance up to the present day, in order to understand all the steps that have characterized the historical evolution; from the first reports, which were essentially letters or warnings sent by clinicians to publishers of important and famous scientific journals, up to today’s modern and ultra-structured electronic registries. The historical phases also help us to understand why pharmacovigilance helped us to achieve such important results for man’s health and for pharmacology itself, and to identify the challenges that await Pharmacovigilance in future years.
Background Side effects of cancer therapy are one of the most important issues faced by cancer patients during their illness. Pharmacovigilance, namely the science and activities aimed at monitoring the safety of drugs, is particularly important in oncology, due to the intrinsic biologic toxicity of antineoplastic agents, their narrow therapeutic windows, and the high doses and rigid timing of treatment regimens. Aim of the review To identify the main issues in carrying out an effective pharmacovigilance activity in oncology. Method We searched PubMed for articles about pharmacovigilance in relation to chemotherapy, radiotherapy and targeted therapy for cancer, using MeSH terms and text words. We also searched Embase, CINAHL, Scopus, Micromedex, the Cochrane Library, two pharmacovigilance databases and the gray literature for articles published in 2012–2018. Overall, 137 articles were considered potentially relevant and were critically appraised independently by two authors, leading to the inclusion of 44 relevant studies, guidelines and reviews. Another 10 important research reports were included in the review. Results Eight critical issues of pharmacovigilance in oncology were identified. These issues pertain to: terminology; range of side effects; targeted therapy and immunotherapy; chemoradiotherapy; generic drugs and biosimilars; drug interactions, pharmacogenetics and polypharmacy; special patient categories; and under-reporting of ADRs. Conclusion The importance of pharmacovigilance in oncology must be highlighted with every effort, to improve safety and offer cancer patients every possible help to improve their quality of life during such a critical period of their lives.Electronic supplementary materialThe online version of this article (10.1007/s11096-018-0706-9) contains supplementary material, which is available to authorized users.
