Results: Lung cancer patients compared to their matched controls had significantly higher mean serum iron level (p = 0.01), ferritin level (p = 0.007) and TIBC (p = 0.006). Analysis revealed that higher concentration of iron and ferritin (IVth quartile) compared to the lower concentration (Ist quartile) was associated with over 2-fold increased lung cancer incidence. We also found that higher transferrin saturation (p = 0.01) and lower TIBC (p<0.01) are associated with better survival of lung cancer patients. The analysis of polymorphisms in iron related genes did not reveal a significant difference between lung cancer patients and controls. However, rs10421768 in HAMP showed a borderline statistically significant correlation with lung cancer risk (OR = 2.83, p = 0.05). Conclusions: The results of this case control study indicate that higher body iron represented by higher Fe and ferritin levels may be associated with lung cancer incidence. Rs10421768 in HAMP may be associated with about 3-times higher lung cancer risk. Higher Fe body content may be associated with better survival of lung cancer patients]]> Wed 26 Oct 2022 11:09:17 AEDT ]]> Do founder mutations characteristic of some cancer sites also predispose to pancreatic cancer? https://novaprd-lb.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://novaprd-lb.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 ]]> Ovarian cancer risk in Polish BRCA1 mutation carriers is not associated with the prohibitin 3' untranslated region polymorphism https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:4382 G, 4154delA) including 127 ovarian cases and 127 unaffected controls who had both breasts and ovaries intact. Controls were matched to cases by year of birth and BRCA1 mutation. Genotyping analysis was performed using PCR-based restriction fragment length polymorphism analysis. Odds ratios (OR) were calculated using conditional and penalized univariable and multivariable logistic regression. Results: A comparison of the genotype frequencies between cases and controls revealed no association of the PHB 3'UTR _CT+TT genotypes with ovarian cancer risk (ORadj 1.34; 95% CI, 0.59–3.11). Conclusion: Our data suggest that the PHB 3'UTR polymorphism does not modify ovarian cancer risk in women carrying one of the three Polish BRCA1 founder mutations.]]> Wed 11 Apr 2018 14:48:22 AEST ]]> Refined histopathological predictors of BRCA1 and BRCA2 mutation status: a large-scale analysis of breast cancer characteristics from the BCAC, CIMBA, and ENIGMA consortia https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:19379 Wed 11 Apr 2018 14:19:24 AEST ]]> Can selenium levels act as a marker of colorectal cancer risk? https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:14831 Wed 11 Apr 2018 13:24:36 AEST ]]> DNA and RNA analyses in detection of genetic predisposition to cancer https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:21177 Wed 11 Apr 2018 13:14:15 AEST ]]> Smoking related cancers and loci at chromosomes 15q25, 5p15, 6p22.1 and 6p21.33 in the Polish population https://novaprd-lb.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://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:23842 Wed 09 Mar 2022 16:01:18 AEDT ]]> Prevalence of BRCA1 and BRCA2 germline mutations in patients with triple-negative breast cancer https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:27801 Wed 04 Apr 2018 17:04:59 AEST ]]> Prevalence of germline TP53 variants among early-onset breast cancer patients from Polish population https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:46235 Tue 15 Nov 2022 08:51:17 AEDT ]]> Association of zinc level and polymorphism in MMP-7 gene with prostate cancer in Polish population https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:35067 853.0–973.9 μg/l). Among five analyzed genetic variants, rs11568818 in MMP-7 appeared to be correlated with 2-fold increased prostate cancer risk (OR = 2.39, 95% CI = 1.19–4.82, p = 0.015). Conclusion: Our results suggest a significant correlation of higher serum zinc levels with the diagnosis of prostate cancer. The polymorphism rs11568818 in MMP-7 gene was also associated with an increased prostate cancer risk in Poland.]]> Thu 04 Nov 2021 10:38:46 AEDT ]]> Genetic contribution to all cancers: the first demonstration using the model of breast cancers from Poland stratified by age at diagnosis and tumour pathology https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:7576 Sat 24 Mar 2018 08:37:24 AEDT ]]> BRCA1-associated breast and ovarian cancer risks in Poland: no association with commonly studied polymorphisms https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:9541 Sat 24 Mar 2018 08:35:48 AEDT ]]> The NOD2 3020insC mutation and the risk of colorectal cancer https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:1921 50 years of age was significantly elevated compared with the control population (odds ratio, 2.23; P = 0.0046). The results indicate that NOD2 may be a predisposing factor to colorectal cancer characterized by an older average age of disease onset in persons who do not harbor any other genetic predisposition to disease.]]> Sat 24 Mar 2018 08:33:08 AEDT ]]> Genetic variation in mitotic regulatory pathway genes is associated with breast tumor grade https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:20582 Sat 24 Mar 2018 07:55:36 AEDT ]]> The VEGF_936_C > T 3 ' UTR polymorphism reduces BRCA1-associated breast cancer risk in Polish women https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:4736 T polymorphism in the VEGF gene and its association with sporadic breast cancer risk has been analyzed in various studies yielding conflicting results. To analyze the role of this polymorphism in modifying hereditary breast and ovarian cancer risks, we conducted a case-control study and genotyped 755 Polish BRCA1 carriers, including 319 breast cancer cases, 146 ovarian cancer cases, and 290 unaffected controls. The results revealed an association of the CT + TT genotypes with a reduced breast cancer risk (ORadj 0.63, 95% CI, 0.41-0.98; ORclustered 0.63, 95% CI, 0.48-0.83), and a potential effect on ovarian cancer risk (ORadj 0.62, 95% CI, 0.33-1.18; ORclustered 0.62, 95% CI, 0.47-0.83). Thus, the 936_C>T polymorphism appears to modify disease risks in BRCA1 carriers.]]> Sat 24 Mar 2018 07:21:09 AEDT ]]> Zinc and Its Antioxidant Properties: The Potential Use of Blood Zinc Levels as a Marker of Cancer Risk in BRCA1 Mutation Carriers https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:55805 Sat 22 Jun 2024 12:53:26 AEST ]]> Blood cadmium levels as a marker for early lung cancer detection https://novaprd-lb.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://novaprd-lb.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 ]]> Blood Lead Level as Marker of Increased Risk of Ovarian Cancer in BRCA1 Carriers https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:55449 13.6 μg/L) were associated with an increased risk of ovarian cancer (univariable: HR = 3.33; 95% CI: 1.23-9.00; p = 0.02; multivariable: HR = 2.10; 95% CI: 0.73-6.01; p = 0.17). No significant correlation was found with breast cancer risk. High blood lead levels are associated with increased risk of ovarian cancer in BRCA1 carriers, suggesting priority for preventive salpingo-oophorectomy. Potential risk reduction strategies include detoxification. Validation in diverse populations and exploration of detoxification methods for lowering lead levels are required.]]> Mon 03 Jun 2024 08:39:06 AEST ]]> Blood Cadmium Level Is a Marker of Cancer Risk in Men https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:55448 0.71 µg/L) had a significantly increased risk of cancer compared to those with low levels (<0.19 µg/L) (HR 3.42, p < 0.001), particularly among non-smokers (HR 3.74, p = 0.003), individuals aged < 60 years (HR 2.79, p = 0.017), and ≥60 (HR 4.63, p = 0.004). The influence of smoking on cancer risk based on Cd levels was not significant in this study. Blood Cd levels may influence cancer risk in men, emphasizing the importance of minimizing Cd exposure to reduce risk. Confirmation of these results in other populations is essential for effective preventive measures against Cd-related cancers.]]> Mon 03 Jun 2024 08:36:29 AEST ]]> Low blood-as levels and selected genotypes appears to be promising biomarkers for occurrence of colorectal cancer in women https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:49791 Fri 02 Jun 2023 17:14:07 AEST ]]>
