Objective: Because birth weight has been positively associated with adult life breast cancer risk and pregnancy estrogens have been hypothesized to affect breast cancer risk in the offspring, we have evaluated the association of pregnancy estriol (E3), estradiol (E2), progesterone and prolactin in maternal serum samples collected during the 16th and 27th gestational week with birth size parameters. Methods: Prospective study of 230 Caucasian women who delivered a live singleton after 37–42 weeks of gestation. Results: E3 at the 27th gestational week was significantly positively associated with birth weight, birth length and placental weight. Progesterone at the 27th gestational week was also significantly positively associated with birth weight and placental weight but, after mutual adjustment among the studied pregnancy hormones, these associations weakened considerably. There was also inconsistent evidence that SHBG and prolactin at the 27th gestational week may be respectively positively and inversely related with birth size parameters. Measurements during the 16th gestational week were generally unrelated to birth size parameters. Conclusions: Because E3 is a dominant estrogen during pregnancy, the positive association of it with birth weight allows the use of the latter as a proxy of in utero exposure to estrogens in breast cancer investigations. 相似文献

Tobacco and alcohol are major risk factors for upper aerodigestive tract (UADT) cancer and significant variation is observed in UADT cancer rates across Europe. We have estimated the proportion of UADT cancer burden explained by tobacco and alcohol and how this varies with the incidence rates across Europe, cancer sub-site, gender and age. This should help estimate the minimum residual burden of other risk factors to UADT cancer, including human papillomavirus. We analysed 1981 UADT cancer cases and 1993 controls from the ARCAGE multicentre study. We estimated the population attributable risk (PAR) of tobacco alone, alcohol alone and their joint effect. Tobacco and alcohol together explained 73% of UADT cancer burden of which nearly 29% was explained by smoking alone, less than 1% due to alcohol on its own and 44% by the joint effect of tobacco and alcohol. Tobacco and alcohol together explained a larger proportion of hypopharyngeal/laryngeal cancer (PAR=85%) than oropharyngeal (PAR=74%), esophageal (PAR=67%) and oral cancer (PAR=61%). Tobacco and alcohol together explain only about half of the total UADT cancer burden among women. Geographically, tobacco and alcohol explained a larger proportion of UADT cancer in central (PAR=84%) than southern (PAR=72%) and western Europe (PAR=67%). While the majority of the UADT cancers in Europe are due to tobacco or the joint effect of tobacco and alcohol, our results support a significant role for other risk factors in particular, for oral and oropharyngeal cancers and also for UADT cancers in southern and western Europe. 相似文献

Interleukin-1 (IL-1) is a cytokine involved in the maturation and proliferation of B cells and plays a significant role in the development of lytic bone lesions, a major clinical feature of multiple myeloma (MM) patients. Genes that regulate products involved in the immune system are highly polymorphic and contribute to inter-individual differences that can influence the genetic predisposition and progression of particular diseases and cancers. In this study, we investigated the correlation between the single nucleotide polymorphisms IL1A -889, IL1B -511, IL1B +3954, IL1RN Mspa1 +11100 and susceptibility to MM in 74 patients and 160 controls. We found that individuals possessing IL1A -889 CT polymorphism had a higher risk in developing MM. Moreover, genotypes IL1B -511 CC, IL1B +3954 CC, IL-1RN Mspa1 +11100 CC and the combination of IL 1B +3954 CC with IL1B -511 CC or IL-1RN Mspa1 +11100 CC exerted a protective effect in individuals possessing them. 相似文献

Human Endogenous Retroviruses (HERVs) are viral sequences integrated into the human genome, resulting from the infection of human germ-line cells by ancient exogenous retroviruses. Despite losing their replication and retrotransposition abilities, HERVs appear to have been co-opted in human physiological functions while their aberrant expression is linked to human disease. The role of HERVs in multiple malignancies has been demonstrated, however, the extent to which HERV activation and expression participate in the development of cancer is not yet fully comprehended. In this review article, we discuss the presumed role of HERVs in carcinogenesis and their promising diagnostic and prognostic implications. Additionally, we explore recent data on the HERVs in cancer therapeutics, either through the manipulation of their expression, to induce antitumor innate immunity responses or as cancer immunotherapy targets. Finally, more precise and higher resolution high-throughput sequencing approaches will further elucidate HERV participation in human physiological and pathological processes. 相似文献

Estrogen receptor (ER) and/or progesterone receptor (PR) expression has been associated with more favorable breast cancer prognosis. Results on the differential association of diet with ER and/or PR positive and negative tumors have been inconclusive. In a large case-control study conducted in Athens, Greece, we investigated whether diet is associated with the expression of ER-alpha or PR in mammary tumors of 421 women with histologically confirmed breast cancer. Diet was assessed through an extensive food frequency questionnaire and results were analyzed using multiple logistic regression. After controlling for non-nutritional variables and mutually adjusting for energy-generating nutrients and ethanol, carbohydrate intake was inversely associated with ER-alpha (P = 0.04) and PR (P = 0.10) expression. The odds ratios (OR) per one standard deviation increment were 0.69 with 95% confidence interval (95% CI) 0.48-0.98 for ER-alpha and 0.72 (95% CI 0.49-1.07) for PR expression. No consistent or statistically significant associations were noted for any of the other energy-generating nutrients or food groups examined. Although in these data no strong relations of qualitative aspects of diet with hormone receptor expression in breast cancer tumors were evident, the inverse association of carbohydrate intake with ER-alpha, and perhaps PR, expression merits further study in future investigations. 相似文献

STUDY OBJECTIVE: To investigate the effect of sevoflurane as single anesthetic on melatonin and beta-endorphin plasma levels during the first 24 hours postoperatively. DESIGN: Prospective, open-cohort study. SETTING: University hospital. PATIENTS: 13 ASA physical status I and II, adults, scheduled for dilatation and curettage of the uterus, and 13 healthy volunteers. INTERVENTIONS: Patients received general anesthesia with sevoflurane. MEASUREMENTS: Melatonin and beta-endorphin plasma levels were determined before anesthesia, immediately after, and two, 4, 8, and 24 hours after the end of anesthesia. Melatonin and beta-endorphin were also measured in 13 healthy subjects (controls) not undergoing anesthesia at similar times during the day. Systolic and diastolic blood pressure, heart rate, bispectral index, and oxygen saturation via pulse oximeter (SpO(2)) were recorded before and after anesthesia. Quality of sleep postoperatively was also assessed. MAIN RESULTS: Melatonin levels (pg/mL) in the patients and controls were 8.2 +/- 7.9 versus 15.2 +/- 15.0 before anesthesia and 7.7 +/- 7.9 versus 11.1 +/- 7.0, 6.5 +/- 6.1 versus 15.6 +/- 16.3, and 19.5 +/- 17.9 versus 23.7 +/- 23.3 at the end of anesthesia and 4 and 24 hours after the end of anesthesia, respectively (P = 0.057). At the same time points, beta-endorphin plasma levels (pmol/L) in patients and controls were 5.2 +/- 2.0 versus 4.0 +/- 2.3, 5.4 +/- 3.3 versus 3.9 +/- 2.5, 4.9 +/- 1.2 versus 4.4 +/- 1.7, and 3.7 +/- 2.6 versus 4.2 +/- 1.8, respectively (P= 0.285). The quality of sleep assessed clinically was not altered. CONCLUSION: Sevoflurane as a single anesthetic for minor gynecological procedures did not influence significantly melatonin or beta-endorphin plasma levels. Sleep quality assessed clinically was not influenced. 相似文献

The authors investigated the role of known risk factors in educational differences in breast cancer incidence. Analyses were based on the European Prospective Investigation Into Cancer and Nutrition and included 242,095 women, 433 cases of in situ breast cancer, and 4,469 cases of invasive breast cancer. Reproductive history (age at first full-term pregnancy and parity), exposure to endogenous and exogenous hormones, height, and health behaviors were accounted for in the analyses. Relative indices of inequality (RII) for education were estimated using Cox regression models. A higher risk of invasive breast cancer was found among women with higher levels of education (RII = 1.22, 95% confidence interval (CI): 1.09, 1.37). This association was not observed among nulliparous women (RII = 1.13, 95% CI: 0.84, 1.52). Inequalities in breast cancer incidence decreased substantially after adjusting for reproductive history (RII = 1.11, 95% CI: 0.98, 1.25), with most of the association being explained by age at first full-term pregnancy. Each other risk factor explained a small additional part of the inequalities in breast cancer incidence. Height accounted for most of the remaining differences in incidence. After adjusting for all known risk factors, the authors found no association between education level and risk of invasive breast cancer. Inequalities in incidence were more pronounced for in situ breast cancer, and those inequalities remained after adjustment for all known risk factors (RII = 1.61, 95% CI: 1.07, 2.41), especially among nulliparous women. 相似文献

Published associations between dietary folate and bladder cancer risk are inconsistent. Biomarkers may provide more accurate measures of nutrient status. This nested case–control analysis within the European Prospective Investigation into Cancer and Nutrition (EPIC) investigated associations between pre-diagnostic serum folate, homocysteine, vitamins B6 and B12 and the risk of urothelial cell carcinomas of the bladder (UCC). A total of 824 patients with newly diagnosed UCC were matched with 824 cohort members. Serum folate, homocysteine, and vitamins B6 and B12 were measured. Odds ratios (OR) and 95% confidence intervals (CI) for total, aggressive, and non-aggressive UCC were estimated using conditional logistic regression with adjustment for smoking status, smoking duration and intensity, and other potential confounders. Additionally, statistical interaction with smoking status was assessed. A halving in serum folate concentrations was moderately associated with risk of UCC (OR: 1.18; 95% CI: 0.98–1.43), in particular aggressive UCC (OR: 1.34; 95% CI: 1.02–1.75; p-heterogeneity = 0.19). Compared to never smokers in the highest quartile of folate concentrations, this association seemed only apparent among current smokers in the lowest quartile of folate concentrations (OR: 6.26; 95% CI: 3.62–10.81, p-interaction = 0.07). Dietary folate was not associated with aggressive UCC (OR: 1.26; 95% CI: 0.81–1.95; p-heterogeneity = 0.14). No association was observed between serum homocysteine, vitamins B6 and B12 and risk of UCC. This study suggests that lower serum folate concentrations are associated with increased UCC risk, in particular aggressive UCC. Residual confounding by smoking cannot be ruled out and these findings require confirmation in future studies with multiple measurements. 相似文献
