Perry’s The Chemotherapy Source Book, now in its fifth edition, provides information on the choice of chemotherapeutic agents, the use of combination chemotherapy, and the toxicity of individual drugs. Organized by site, this is the only book of its kind to focus strictly on the clinical practice of chemotherapy, and is meant to serve as a “one-stop shop” for information on choice of chemotherapeutic agents, treatment outlines, grading of side effects, and dose modification.
