Claim One:
1. A method for determining prognosis or outcome of a cancer in a patient, comprising (1) performing a method selected from the group consisting of nucleic acid hybridization, nucleic acid amplification and an immunological method in order to determine the expression levels of a set of two or more genes, wherein the set comprises at least one upregulated gene (A) that is expressed in greater amounts in tumor samples from a predictor population having the cancer and having a good prognosis or outcome than in tumor samples from the predictor population having the cancer and having a poor prognosis or outcome and at least one downregulated gene (B) that is expressed in lesser amounts in the tumor samples from the predictor population having the cancer and having a good prognosis or outcome than in the tumor samples from the predictor population having the cancer and having a poor prognosis or outcome, wherein the upregulated and downregulated genes are selected as having statistically significant differences in mean expression levels, (2) calculating at least one patient ratio (R) of the expression level of the at least one upregulated gene (A) to the expression level of the at least one downregulated gene (B), wherein the at least one patient ratio (R) is indicative of the prognosis or outcome of the cancer patient, and (3) comparing the patient ratio (R) and a threshold (T) wherein (i) (T) divides the predictor population such that a ratio (R) of the expression of (A) to (B) in the predictor population that is higher than the threshold corresponds to a good prognosis or outcome of a cancer and a ratio (R) of the expression of (A) to (B) in the predictor population that is below the threshold corresponds to a bad prognosis or outcome of a cancer, (ii) a patient ratio (R) greater than the threshold (T) indicates a better prognosis or outcome of the cancer in the patient than does a patient ratio (R) smaller than the threshold (T), (iii) if the ratio (R) is set to a threshold of one, a ratio greater than one indicates a greater statistical likelihood of a good prognosis or outcome of the cancer and a ratio less than one indicates a greater statistical likelihood of a bad prognosis or outcome of the cancer, and wherein (iv) the patient ratio (R) and threshold (T) are used by a healthcare professional in the selection of a treatment for the patient.
