Considering their novelty and cost, post‐marketing evaluation is highly relevant for new anticancer drugs. Identify and characterize available and potentially useful databases for post‐marketing evaluation of these specific drugs is necessary. A review was conducted to identify available and accessible databases to study the post‐marketing evaluation of drugs in real‐life care setting. Databases identified have been classified into medico‐administrative databases, medical record databases, and databases resulting from ad hoc collections. Taking as examples databases available in France, each type was described as well as its strengths and limits for a potential use in the oncology field. Record linkage of medico‐administrative databases could cover almost the whole population and is now used to evaluate anticancer drugs (e.g., Système National des Données de Santé). Large medical record databases are still lacking, but efforts are currently made to give access to hospital data warehouses for research purposes. Finally, databases resulting from ad hoc collections are also available for some cancer localizations and allow to obtain highly valuable clinical and biological data. A range of important and valuable databases exist but, individually, none is enough to answer to all questions from health authorities, healthcare professionals, and patients. In order to obtain a complete overview on utilization, associated health outcomes and costs of these drugs, it seems necessary to better interlink available databases.
