Abstract BackgroundNigeria has the highest cancer burden in Africa with 124,815 cancer cases and 78,899 cancer deaths in 2020. The limited number of oncology specialists, inaccessibility of essential cancer medicines like chemotherapies, and suboptimal delivery of cancer care lead to poor treatment outcomes. Oncology pharmacy (OP) practitioners are critical oncology professionals in the multidisciplinary team (MDT) for cancer treatment globally. In Nigeria, there is a limited number of OP practitioners providing services like reconstitution of chemotherapy, clinical research, safe use of biosafety cabinets, and monitoring of adverse drug reactions. Although the interest in oncology pharmacy is increasing, the educational needs, available skill sets, and directed training in oncology pharmacy across the nation are unknown. In this study, we examined the educational needs of OP practitioners and worked with the West African College of Pharmacy West African Postgraduate College of Pharmacists (WAPCP), Oncology Pharmacy Practitioners Association of Nigeria (OPPAN), and the International Society of Oncology Pharmacy Practitioners to upgrade the oncology pharmacy practice in Nigeria. MethodA cross-sectional study with a semi-structured questionnaire was done in 2021 with 39 pharmacists working in oncology centers across Nigeria. General descriptive statistics and qualitative analysis was performed. ResultsThere is no board-certified oncology pharmacist in Nigeria. More than 50% of the general pharmacists working in oncology centers are responsible for chemotherapy reconstitution. Understanding chemotherapy reconstitution (automation of chemotherapeutic mixing, use of radiopharmaceuticals, etc), use of biosafety cabinets, knowledge of pharmacology, designing treatment protocols, data management, immunotherapy delivery, and oncology clinical trials were some of the most significant educational needs of the OP practitioners in Nigeria. OP practitioners are lacking in most cancer centers and MDTs. ConclusionThere is an urgent need for a specialty postgraduate training programme in oncology pharmacy in Nigeria. This would help increase oncology clinical trials, improve delivery of cancer medicines, quality of care, and management of toxicities. The West African Postgraduate College of Pharmacists and OPPAN need appropriate training resources to develop an oncology pharmacy curriculum, promote the specialty and collaborate with global institutions for board certifications.
