This chapter presents the definition, classification, incidence/prevalence, economic impact, etiology and risk factors, and pathology/pathogenesis of geriatric oncology. It also includes the potential pitfalls/common errors made regarding diagnosis of disease, treatment, prevention/management of complications, important scientific studies, evidence-based clinical data, and essential social guidelines for geriatric oncology. Geriatric oncology is a multidisciplinary field addressing the prevention, diagnosis, and treatment of cancer in older adults. The comprehensive geriatric assessment (CGA) is a multidimensional instrument used to collect data on medical, psychosocial, and functional capabilities of older adults. The CGA can be used to identify problems that may limit a patient’s ability to tolerate standard cancer treatments, and thus provides actionable information to guide interventions that can improve the patient’s ability to undergo treatment. Although most cancer diagnoses are among older adults, this population is highly underrepresented in clinical trials, and thus significant opportunities exist for further research in this emerging discipline.
