S-1 is a newly developed dihydropyrimidine dehydrogenase inhibitory fluoropyrimidine that exhibits high clinical efficacy against non-small cell lung cancers. To identify genes that may be associated with chemosensitivity to the antitumor drug S-1, we used a low density array representing 93 genes to analyze expression profiles in 4 orthotopically implanted lung cancers derived from human lung cancer cell lines (Lu99, Lu130, LC6 and A549). The tumor growth inhibition (TGI) rates of S-1 in orthotopically implanted tumors of the Lu99, Lu130, LC6 and A549 cell lines were 34.6, 37.5, 32.1 and 3.6%, respectively. The expression of the PRSS3, ABCC4, TXN, SHMT1 and CMPK genes was significantly promoted in the orthotopically implanted SCID mouse model of the 4 lung cancer cell lines by the administration of S-1, while the expression of the LMO7 and FOLH1 genes was significantly suppressed. The expression of the ABCC1, 2 and TST genes was negatively correlated with TGI. The expression of the TK1 and ERCC2 genes was positively correlated with TGI. The results of the present study suggest that the expression of the ABCC1, 2, TST, TK1 and ERCC2 genes is related to resistance to the antitumor drug S-1.

The objective of the study was to investigate whether specific single nucleotide polymorphisms (SNPs) with influence on drug transport, biotransformation and repair mechanisms are associated with treatment outcome and toxicity in metastatic colorectal cancer (mCRC). We genotyped blood samples from 519 mCRC patients treated with first-line 5-fluorouracil and oxaliplatin +/- cetuximab for 17 SNPs in 10 genes involved in membrane transport (ABCC1 and ABCC2), drug biotransformation (GSTP1 and AGXT) and DNA repair (ERCC1, ERCC2, XRCC1, XRCC3, XPG and MSH6). The AGXT-rs34116584 and the ERCC2-rs238406 polymorphisms were significantly associated with progression-free survival (P=0.002 and P=0.001, respectively). Associations between 18 toxicity variables and SNPs were identified, although none were significant after Bonferroni correction for multiple comparisons. The study identified SNPs of potential use as markers of clinical outcome in oxaliplatin-treated mCRC patients. If validated in other studies, they could improve the selection of therapy in mCRC.
