Title:	Six-gene biomarker of survival and response to platinum based chemotherapy in serious ovarian cancer patients
Abstract:	Described herein are methods of predicting the risk of developing ovarian cancer recurrence of a subject comprising the steps of detecting the expression levels of at least four of the six genes selected from the group consisting of AKT2, KRAS, RAC1, CALM3, RPS6KA2 and YWHAB or the gene products thereof, wherein the presence of increased expression levels of the genes or the gene products is predictive of the increased risk of developing ovarian cancer recurrence in the subject. Kits for practicing the methods are also disclosed.

Application Number:	15/339,109
Patent Claims:	1. A method of treating a subject having ovarian cancer, the method comprising the steps of: (a) obtaining a first sample from the subject prior to treatment for ovarian cancer, (b) measuring the expression level of AKT2, KRAS, RAC1, and CALM3 in the sample from (a), (c) obtaining a second sample from the subject after treatment for ovarian cancer, (d) measuring the expression level of AKT2, KRAS, RAC1, and CALM3 in the sample from (c), (e) detecting an increased level of expression of the genes in the second sample, as compared to the level of expression of the genes in the first sample, wherein the increased level of expression is at least 1%, (f) diagnosing the subject as in need of alternative therapy, and (g) administering to the diagnosed subject an alternative therapy selected from the group consisting of taxane, bevacizumab, docetaxel, doxorubicin, gemcitabine, pemetrexed, tamoxifen, topotecan, and mixtures thereof. 2. The method of claim 1 wherein the treatment for ovarian cancer is platinum based chemotherapy. 3. The method of claim 1 wherein the alternative therapy is administered with platinum. 4. The method of claim 1 wherein the alternative therapy is used without platinum. 5. A method for reducing the risk of recurrence in a subject having ovarian cancer, the method comprising the steps of: (a) obtaining a first sample from the subject prior to treatment for ovarian cancer, (b) measuring the expression level of AKT2, KRAS, RAC1, and CALM3 in the sample from (a), (c) obtaining a second sample from the subject after treatment for ovarian cancer, (d) measuring the expression level of AKT2, KRAS, RAC1, and CALM3 in the sample from (c), (e) detecting an increased level of expression of the genes in the second sample, as compared to the level of expression of the genes in the first sample, wherein the increased level of expression is at least 1%, (f) diagnosing the subject as being at risk of recurrence of ovarian cancer, and (g) administering to the diagnosed subject an alternative therapy selected from the group consisting of taxane, bevacizumab, docetaxel, doxorubicin, gemcitabine, pemetrexed, tamoxifen, topotecan, and mixtures thereof. 6. The method of claim 5 wherein the treatment for ovarian cancer is platinum based chemotherapy. 7. The method of claim 5 wherein the alternative therapy is administered with platinum. 8. The method of claim 5 wherein the alternative therapy is used without platinum. 9. The method of claim 1, wherein the alternative therapy is taxane. 10. The method of claim 5, wherein the alternative therapy is taxane.
