Abstract: The present invention relates to methods for the diagnosis and treatment of a cancer or cancer. Specifically, the present invention identifies the differential expression of 140, 1470, 1686, 2089, 2427, 3702, 5891, 6428, 7181, 7660, 25641, 69583, 49863, 8897, 1682, 17667, 9235, 3703, 14171, 10359, 1660, 1450, 18894, 2088, 32427, 2160, 9252, 9389, 1642, 85269, 10297, 1584, 9525, 14124, 4469, 8990, 2100, 9288, 64698, 10480, 20893, 33230, 1586, 9943, 16334, 68862, 9011, 14031, 6178, 21225, 1420, 32236, 2099, 2150, 26583, 2784, 8941, 9811, 27444, 50566 and 66428 genes in tissues relating to cancer, relative to their expression in normal, or non-cancer disease states, and/or in response to manipulations relevant to a cancer. The present invention describes methods for the diagnostic evaluation and prognosis of various cancers, and for the identification of subjects exhibiting a predisposition to such conditions.
