TL;DR: A role for p53PIN3 in tumorigenesis is suggested, supported by the in vitro characterization of this variant, with the same order of magnitude as that observed in previous studies for other types of cancer.
Abstract: We undertook a case–control study to examine the possible associations of the TP53 variants Arg>Pro at codon 72 and p53PIN3, a 16 bp insertion/duplication in intron 3, with the risk of colorectal cancer (CRC). The p53PIN3 A2 allele (16 bp duplication) was associated with an increased risk (OR 1.55, 95% CI 1.10−2.18, P=0.012), of the same order of magnitude as that observed in previous studies for other types of cancer. The Pro72 allele was weakly associated with CRC (OR=1.34, 95% CI 0.98−1.84, P=0.066). The possible functional role of p53PIN3 was investigated by examining the TP53 mRNA transcripts in 15 lymphoblastoid cell lines with different genotypes. The possibility that the insertion/deletion could lead to alternatively spliced mRNAs was excluded. However, we found reduced levels of TP53 mRNA associated with the A2 allele. In conclusion, the epidemiological study suggests a role for p53PIN3 in tumorigenesis, supported by the in vitro characterization of this variant.

TL;DR: Investigation of the relationship between exposure to naturally occurring erionite fibres and the reported high incidence of malignant mesotheliomas in Central Cappadocia indicates erionites fibres as a carcinogenic agent, although some aspects of the exposure are not fully clarified.
Abstract: An environmental and epidemiological study has been carried out in Central Cappadocia, Turkey, aiming at investigating the relationship between exposure to naturally occurring erionite fibres and the reported high incidence of malignant mesotheliomas. Airborne fibre levels are generally low but show a higher proportion of erionite fibres in the villages affected by malignant disease than in a control village. The same pattern is confirmed by analysis of the fibre content in lung tissues of sheep from several villages, both affected and unaffected by malignant disease. The 3 villages with the highest proportion of erionite fibres have high rates of malignant pleural mesothelioma, malignant peritoneal mesothelioma and lung cancer. No case of malignancy for the same sites has been reported during the study period from the control village. The relationships between these findings and their consistency with the results from experimental studies indicate erionite fibres as a carcinogenic agent, although some aspects of the exposure are not fully clarified.

TL;DR: The overall role of GST polymorphisms in modifying the lung cancer risk may be more limited than has been so far anticipated.
Abstract: Glutathione S-transferases (GSTs) are known to take part in detoxification of many potentially carcinogenic compounds Therefore, polymorphisms of the GST genes have been considered as potentially important modifiers of individual risk of environmentally induced cancers The association between lack of glutathione S-transferase M1 gene (GSTM1 null genotype) and susceptibility to smoking-related lung cancer has been actively studied, with contradictory results In contrast, little is known about the more recently found polymorphisms in GSTM3, GSTP1 and GSTT1 genes with respect to individual responses to environmental exposures In this study, we determined the genotype distribution of all these genes, and their combinations, among 208 Finnish lung cancer patients and 294 population controls None of the genotypes studied had a statistically significant effect on lung cancer risk, when studied separately However, a significant association was observed for concurrent lack of the GSTM1 and GSTT1 genes and susceptibility to squamous cell carcinoma For that cell type, the risk was more than 2-fold when compared with that of individuals having other genotype combinations (OR = 23; 95% CI = 10–53; p = 005) Moreover, the risk was mostly attributable to patients with smoking history of 40 pack-years or less (OR = 29; 95% CI = 11–77; p = 003) In contrast, this genotype combination did not affect the risk for other histological types of lung cancer, and the other genotype combinations had no effects on individual susceptibility to this malignancy The overall role of GST polymorphisms in modifying the lung cancer risk may therefore be more limited than has been so far anticipated Int J Cancer 77:516–521, 1998 © 1998 Wiley-Liss, Inc

TL;DR: BRCA1 and BRCA2 mutation carriers older than 40 years show a similar reduction in breast cancer risk with increasing parity as non-carriers.
Abstract: Multiparity, young age at first childbirth, and breast-feeding are associated with a reduced risk of breast cancer in the general population. The breast cancer predisposition gene, BRCA1, regulates normal cell differentiation. Because mammary gland cells divide and differentiate during pregnancy, reproductive factors may influence breast cancer risk in BRCA1/2 mutation carriers differently than they do in noncarriers. Methods: We performed a retrospective cohort study of 1601 women in the International BRCA1/2 Carrier Cohort Study cohort, all of whom carried a mutation in BRCA1 or BRCA2. Information on reproductive factors was obtained from a questionnaire. At the time of interview 853 subjects were classified with breast cancer. Data were analyzed by using a weighted cohort approach. All statistical tests were two-sided. Results: There was no statistically significant difference in the risk of breast cancer between parous and nulliparous women. Among parous women, an increasing number of full-term pregnancies was associated with a statistically significant decrease in the risk of breast cancer (P-trend =.008); risk was reduced by 14% (95% confidence interval [CI] = 6% to 22%) for each additional birth. This association was the same for carriers of mutations in either BRCA1 or BRCA2 and was restricted to women older than 40 years. In BRCA2 mutation carriers, first childbirth at later ages was associated with an increased risk of breast cancer compared with first childbirth before age 20 years (20-24 years, hazard ratio [HR] = 2.33 [95% CI = 0.93 to 5.83]; 25-29 years, HR = 2.68 [95% CI 1.02 to 7.07]; 30 years, HR = 1.97 [95% CI = 0.67 to 5.81]), whereas in BRCA1 mutation carriers, first childbirth at age 30 years or later was associated with a reduced risk of breast cancer compared with first childbirth before age 20 years (HR = 0.58 [95% CI = 0.36 to 0.94]). Neither history of interrupted pregnancies (induced abortions or miscarriage) nor history of breast-feeding was statistically significantly associated with the risk of breast cancer. Conclusions: BRCA1 and BRCA2 mutation carriers older than 40 years show a similar reduction in breast cancer risk with increasing parity as non-carriers.

TL;DR: High prevalence of HPV in all age groups may be a distinctive feature of populations where HPV transmission continues into middle age and cervical cancer incidence is very high.
