A broad and experienced team, including medical oncologists and life scientists, have collaborated to produce this practical guide to cancer immunotherapy. It provides a compendium of best practice, including 23 case studies to act as models for professionals to make decisions, either for individual patients or as the basis for using immunotherapy across an organisation, planning area, region or country. As well as introducing all key concepts, expert practitioners provide a guide to future treatments using novel technologies, discuss key problems and suggest solutions, and consider the costs of immunotherapy treatments.This guide also makes an excellent training tool, which will help new teams and clinical staff to develop procedures, and adopt best practice. This resource is produced in partnership with the Association of Cancer Physicians (ACP).
