Abstract: The present invention relates to the use of genomic polymorphism to provide individualized therapeutic regimens to treat patients suffering from diseases such as cancer. The invention discloses methods for determining the efficacy or choice of chemotherapeutic drugs and regimens for use in treating a diseased patient by associating genomic polymorphism with the effectiveness of the drugs or regimens, or by associating genomic polymorphism with the intratumoral expression of a gene whereby the gene expression affects effectiveness of the drugs or regimens. In particular, the present invention provides novel methods for screening therapeutic regimens, which comprise determining a patient's genotype at a tandemly repeated 28 base pair region in the thymidilate synthase (TS) gene's 5? untranslated region (UTR).

Abstract: The present invention provides for a method for identifying patients that are suitably treated by a therapy, such as a therapy involving administration of a fluoropyrimidine drug and/or a platinum drug. The method includes determining the expression level of at least one gene selected from a phospholipase 2 (PLA2) gene, a thymidine phosphorylase (TP) gene, and a glutathione S-transferase P1 (GSTP-1) gene in suitable sample isolated from the patient. Overexpression of the gene or genes identifies the patient as not being suitable for the therapy.

Abstract: A method for determining whether a patient in need thereof will respond to anti-VEGF antibody based chemotherapy by screening a suitable cell or tissue sample isolated from the patient for at least one genomic polymorphism or genotype selected from (i) IL-8(?251); (ii) VEGF(936); or (iii) AM (3? CA repeats), wherein the patient is suitably treated if the corresponding genotype is (i) (T/T) for IL-8(?251); (ii) (T/T or C/T) for VEGF(936); or (iii) at least one AM allele having 14 or more 3? CA repeats.

Abstract: The present invention discloses a novel single nucleotide polymorphism (SNP) in the isolated 5? tandem repeats of the thymidylate synthase (TS) gene and methods for its use. The novel SNP, located in the 12th nucleotide of a 28 bp third tandem repeat (3R) of the TS gene, substitutes a C for a G, and is the variant form of the repeat. Subjects with the wild-type form of 3R have greater transcription of the TS gene than subjects with the variant form. The invention also reveals that a six base pair deletion in the 3? region of TS (?6 bp/1494) indicates mRNA instability and thus reduced production of TS. In diseased tissue, such as cancer, reduced production of TS is beneficial because it prevents the cancerous cells from growing and spreading. Analysis of either polymorphism or both together allows for prediction of a subject's response to chemotherapeutic and anti-cardiovascular disease treatments because both diseases are related to TS levels in a subject.
