A replication study using a set of 1,200 melanoma patient DNA samples and similarly large series of healthy controls was undertaken. Results: We selected 21 potentially deleterious variants in 20 genes (VRK1, MYCT1, DNAH14, CASC3, MS4A12, PRC1, WWOX, CARD6, EXO5, CASC3, CASP8AP2, STK33, SAMD11, CNDP2, CPNE1, EFCAB6, CABLES1, LEKR1, NUDT17, and RRP15), which were identified by WES and confirmed by Sanger sequencing for an association study. Evaluation of the allele distribution among carriers and their relatives in available family trios revealed that these variants were unlikely to account for many familial cases of melanoma. Replication study revealed no statistically significant differences between cases and controls. Conclusion: Although most of the changes seemed to be neutral we could not exclude an association between variants in VRK1, CREB3L3, EXO5, and STK33 with melanoma risk.]]> Wed 26 Oct 2022 09:22:11 AEDT ]]> Do founder mutations characteristic of some cancer sites also predispose to pancreatic cancer? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24833 A, del5395, I157T), NBS1 (657del5) and PALB2 (509-510delGA, 172-175delTTGT). A statistically significant association between the 657del5 mutation and an increased risk of pancreatic cancer was observed for NBS1 gene. The Slavic NBS1 gene mutation (657delACAAA) was detected in 8 of 383 (2.09%) unselected cases compared with 22 of 4,000 (0.55%) controls (OR: 3.80, p = 0.002). The PALB2 509_510delGA and 172-175delTTGT mutations combined were seen in 2 (0.52%) unselected cases of PaCa and in 8 (0.20%) of 4,000 controls (OR: 2.61, p = 0.49). For BRCA1, the three mutations combined were detected in 4 of 383 (1.04%) PaCa patients and in 17 of 4,000 (0.42%) controls (OR: 2.46, p = 0.20). CHEK2 mutations were not associated with the risk of pancreatic cancer (OR: 1.11, p = 0.72). The founder mutation in NBS1 (657del5) was associated with an increased risk of PaCa in heterozygous carriers, indicating that this mutation appears to predispose to cancer of the pancreas. By identifying pancreatic cancer risk groups, founder mutation testing in Poland should be considered for people at risk for PaCa.]]> Wed 24 Nov 2021 15:53:13 AEDT ]]> Influence of the selenium level on overall survival in lung cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37060 69 µg/L, reference). The 80 months crude survival after diagnosis was 79.5% (95% CI: 68.5-92.4%) for individuals in the highest tertile and 58.1% (95% CI: 45.1-74.9%) for individuals in the lowest tertile with stage I lung cancer. Conclusion: These results suggest that in patients undergoing treatment for stage I lung cancer, serum selenium levels at the time of diagnosis (>69 µg/L) may be associated with improved overall survival.]]> Wed 19 Jan 2022 15:19:20 AEDT ]]> Can selenium levels act as a marker of colorectal cancer risk? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14831 Wed 11 Apr 2018 13:24:36 AEST ]]> Smoking related cancers and loci at chromosomes 15q25, 5p15, 6p22.1 and 6p21.33 in the Polish population https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13891 Wed 11 Apr 2018 12:00:00 AEST ]]> Serum concentrations of selenium and copper in patients diagnosed with pancreatic cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23842 Wed 09 Mar 2022 16:01:18 AEDT ]]> Blood cadmium levels as a marker for early lung cancer detection https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38391 Mon 29 Jan 2024 18:44:32 AEDT ]]> Influence of the levels of arsenic, cadmium, mercury and lead on overall survival in lung cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48683 1.97–7.77 µg/L) compared to quartile I (0.23–0.57 µg/L, reference). This study revealed that low blood cadmium levels <1.47 µg/L are probably associated with improved overall survival in treated patients with stage IA disease.]]> Mon 27 Mar 2023 14:53:43 AEDT ]]> BRCA1/2 mutations are not a common cause of malignant melanoma in the Polish population https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42998 A and c.4534 C>T. Disease allele frequency was evaluated by genotyping of 1230 consecutive melanoma cases, 5000 breast cancer patients, 3500 prostate cancers and 9900 controls. Both variants were found to be absent among unselected cancer patients and healthy controls. The MutationTaster, Polyphen2 and SIFT algorithms indicate that c.9334G>A is a damaging variant. Due to lack of tumour tissue LOH analysis could not be performed for this variant. The variant segregated with the disease. The c.4534 C>T variant did not segregate with disease, there was no LOH of the variant. The c.9334G>A variant, classified as a rare variant of unknown significance, on current evidence may predisposes to cancers of the breast, prostate and melanoma. Functional studies to describe how the DNA change affects the protein function and a large multi-center study to evaluate its penetrance are required. © 2018 DeÎbniak et al.
