An in vitro model to optimize dose scheduling of multimodal radioimmunotherapy and chemotherapy: effects of p53 expression.

Several reports have appeared on the use of combined radioimmunotherapy (RAIT) and chemotherapy. The choice of drug to use with RAIT and how to space the two treatments has not been completely addressed. Because every patient's cancer presents with a specific molecular phenotype, we hypothesized that it may be necessary to tailor therapy based on specific gene expression.
