  A prototype for a web application was designed and implemented as a guide to
be used by clinicians when designing the best drug therapy for a specific
cancer patient, given biological data derived from the patients tumor tissue
biopsy. A representation of the patients metabolic pathways is displayed as a
graph in the application, with nodes as substrates and products and edges as
enzymes. The top metabolically active sub- paths in the pathway, ranked using
an algorithm based on both the patients biological data and the graph topology,
are also displayed and can be individually highlighted to examine potential
enzymatic sites to be disrupted by a drug.
