Risk factors for male breast cancer.

Risk factors for male breast cancer were investigated in a case-control study of 21 cases and 82 controls admitted to hospital for acute, non-neoplastic, non-hormone-related diseases in the Greater Milan area between 1988 and 1994. More educated men tended to be at higher risk of breast cancer, with a multivariate odds ratio (OR) of 2.6 [95% confidence interval (CI) 0.7-9.4]. The OR was 3.2 (95% CI 1.1-9.6) for those in the higher social class. Men with no offspring were at higher risk than fathers, with an OR of 5.5 (95% CI 1.8-16.7). A history of breast cancer in female relatives was reported by two cases and one control, giving an OR of 8.5 (95% CI 1.1-69.0). Cases were somewhat heavier than controls, and significantly taller, with an OR of 5.7 (95% CI 1.6-19.9) for subjects taller than 170 cm vs shorter ones. The association with weight, however, decreased after allowance for height, and no difference was observed for body mass index. Socioeconomic correlates and family history are similar to well-assessed risk factors for female breast cancer. The associations with anthropometric measures and childlessness may find an explanation in chromosomal abnormalities, such as Klinefelter's syndrome, or other hormone-related disorders

Descriptive epidemiology of vulvar and vaginal cancers in Vaud, Switzerland, 1974-1994

Background: To analyse trends in incidence, survival and risk of second neoplasms following vaginal and vulvar cancers using data collected by the Swiss Cancer Registry of Vaud over the 21-year period 1974-1994. Materials and methods: Subjects were 257 vulvo-vaginal cancers. Of these, 69 were vaginal, 153 vulvar cancers, and 35 non-specified lower genital tract neoplasms; 94 in situ neoplasms were also registered (85 for the vulva). Results: Invasive vaginal cancer incidence decreased from 0.8 in 1974-1984 to 0.4/100,000 women in 1985-1994, while invasive vulvar cancer incidence remained approximately stable around 1.2/100,000 (world standard); incidence of in situ vulvar cancer increased from 0.8 to 1.3/100,000, the rise being larger in younger women. Significant excesses for second primary neoplasms were observed for oro-pharyngeal and lung cancer, and for non-melanomatous skin neoplasms, as well as for invasive vulvar cancers following in situ cancers. Conclusions: This population-based dataset confirms that the incidence of in situ vulvar (but not invasive vulvar or vaginal cancer) has been increasing over the last 20 years. The excess second primary neoplasms supports the hypotheses that human papillomavirus and cigarette smoking are related to vulvo-vaginal neoplasm

Cervical cancer mortality in young adult European women

Background: The process of social, political and economic transformation, which took place in Central and Eastern Europe in the early 90's, has affected many spheres of Europeans' lives, including health-associated issues. These changes also had an impact on mortality rates due to cervical cancer (CC). Therefore, the aim of this study was to analyse CC mortality trends in Europe after 1990. Methods: Data on death due to CC, uterine cancers and unspecified uterine cancers, in women aged 20\u201344, were taken from the WHO Mortality Database. Trends in European countries between 1990 and 2017 were assessed using the Joinpoint Regression Program. Results: Most of the countries experienced a decrease in CC mortality. Although the lowest rates were observed in EU15 Member States, the highest decreases were observed in Central and Eastern Europe. However, there are still differences in mortality in these countries. There are also a few countries like Belarus, Latvia and Ukraine, which experienced an increase in mortality. The range of mortality across Europe in 2017 was between 0.6 and 5.2/100,000 women. Conclusions: It is essential to introduce well-organised screening programmes for early detection of CC with coverage of a correspondingly high percentage of the population, particularly in East-Central Europe, as well as to introduce high-coverage HPV vaccination in all European countries

Dietary approach to stop hypertension (DASH) diet and associated socioeconomic inequalities in the United Kingdom

The dietary approach to stop hypertension (DASH) diet is an effective measure in the prevention and treatment of CVD. We evaluated recent trends in socioeconomic differences in the DASH score in the UK population, using education, occupation and income as proxies of socioeconomic position (SEP). We analyzed data on 6416 subjects aged 18 and older collected in the National Diet and Nutrition Survey (NDNS 2008-2016). The DASH score was calculated using sex-specific quintiles of DASH items. Multiple linear regression and quantile regression models were used to evaluate the trend in DASH score according to SEP. The mean DASH score was 24 (standard deviation: 5). The estimated mean differences between people with no qualification and those having the highest level of education was -3.61 points (95% CI: -4.00; -3.22). The mean difference between subjects engaged in routine occupations and those engaged in high managerial and professional occupations was -3.41 points (95% CI: -3.89; -2.93) and for those in the first fifth and last fifth of the household income distribution was -2.71 points (95% CI: -3.15; -2.28). DASH score improved over time and no significant differences in the trend were observed across SEP. The widest socioeconomic differences emerged for consumption of fruit, vegetables, wholegrains, nuts, seeds and legumes. Despite an overall increase in the DASH score, a persisting SEP gap was observed. This is an important limiting factor in reducing the high socioeconomic inequality in CVD observed in the UK

Intrauterine device use and risk of endometrial cancer.

The relationship between intrauterine device (IUD) use and risk of endometrial cancer has been analysed in a case-control study conducted in Italy between 1983 and 1992, including 453 patients with histologically confirmed endometrial cancer and 1,451 controls admitted for acute, non-gynaecological, non-hormonal, non-neoplastic conditions to the same network of hospitals where cases had been identified. Two (0.4%) cases versus 36 (2.3%) controls reported ever using an IUD. The corresponding multivariate relative risk was 0.4 (95% CI 0.1-1.0). The results of this study and the few published available epidemiological data suggest a protective role of IUD use on endometrial carcinogenesis, but potential selective mechanisms for IUD utilisation (indication bias) should be carefully considered in the interpretation
