1. A method of treating prostate cancer in a patient comprising:
(1) obtaining a sample comprising prostate cancer tumor tissue from said patient;
(2) determining by quantitative real-time PCR of cDNA the expression of a panel of genes comprising ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A in said sample comprising prostate cancer tumor tissue;
(3) prognosing said patient as having a decreased likelihood of prostate cancer progression when the average expression of the genes ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A is lower than a threshold index value; and
(4) administering to said patient active surveillance based on the prognosis.
2. The method of claim 1 , wherein said determining step further comprises determining the expression of one or more housekeeping genes in said sample.
3. The method of claim 2 , wherein said determining step further comprises normalizing the expression of the genes ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A using the expression of the housekeeping genes.
4. The method of claim 3 , wherein the housekeeping genes comprise the genes RPL38, UBA52, PSMC1, RPL4, RPL37, RPS29, SLC25A3, CLTC, TXNL1, PSMA1, RPL8, MMADHC, RPL13A, LOC728658, PPP2CA and MRFAP1.
5. A method of treating prostate cancer in a patient comprising:
(1) obtaining a sample comprising prostate cancer tumor tissue from said patient;
(2) determining by quantitative PCR of cDNA the expression of a panel of genes comprising ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A in said sample comprising prostate cancer tumor tissue;
(3) prognosing said patient as having an increased likelihood of prostate cancer progression when the average expression of the genes ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A exceeds a threshold index value; and
(4) administering to said patient one or more of chemotherapy, radiation therapy or surgery based on the prognosis.
6. The method of claim 5 , wherein said determining step further comprises determining the expression of one or more housekeeping genes in said sample.
7. The method of claim 6 , wherein said determining step further comprises normalizing the expression of the genes ASF1B, ASPM, BIRC5, BUB1B, C18orf24, CDC2, CDC20, CDCA3, CDCA8, CDKN3, CENPF, CENPM, CEP55, DLGAP5, DTL, FOXM1, KIAA0101, KIF11, KIF20A, MCM10, NUSAP1, ORC6L, PBK, PLK1, PRC1, PTTG1, RAD51, RAD54L, RRM2, TK1 and TOP2A using the expression of the housekeeping genes.
8. The method of claim 7 , wherein the housekeeping genes comprise the genes RPL38, UBA52, PSMC1, RPL4, RPL37, RPS29, SLC25A3, CLTC, TXNL1, PSMA1, RPL8, MMADHC, RPL13A, LOC728658, PPP2CA and MRFAP1.
