Chemotherapy-Related Side Effects in Childhood Acute Lymphoblastic Leukemia in Indonesia: Parental Perceptions

Noncompliance with prescribed medication has been associated with increased chance of relapse and poor outcome. Side effects may be an important cause of noncompliance. Fifty-one parents of children with acute lymphoblastic leukemia in a tertiary care hospital in Indonesia were interviewed about their perception of side effects and their impact on treatment noncompliance and daily activities.
