The invention provides a computer network comprising a first computer and one or more second computers that are in electronic communication with each other. The first computer is associated with a first health care facility and has instructions for retrieving, over a network, one or more data structures for a patient enrolled in a health care program. The one or more data structures for the patient collectively comprise (i) a patient identifier, (ii) a molecular profile from a biological specimen obtained from the patient at the first health care facility; and (iii) a clinical characterization of the patient that was made at the first health care facility. The first computer has instructions for retrieving, over the network connection, one or a plurality of treatment regimens that are deemed suitable for the patient based upon the molecular profile and the clinical characterization of the patient. The one or more second computers are at one or more locations other than the first health care facility and have one or more data structures for each patient in a plurality of patients enrolled in the health care program
