Complications of Targeted Drug Therapies for Solid Malignancies: Manifestations and Mechanisms

OBJECTIVE: This article reviews important complications of targeted drug therapies for solid malignancies that can be identified on diagnostic imaging. Wherever possible, known or proposed mechanistic explanations for drug complications are emphasized. CONCLUSION: Familiarity with the toxicity profiles of different targeted cancer therapies is important for identifying drug-related complications and for differentiating drug effects from disease progression. A mechanistic understanding may be useful for associating individual drugs with their complications and for predicting the complications of emerging agents.
