“…The likely effect of such a risk factor is difficult to assess given a lack of knowledge as to its prevalence of the condition. If we assume the ectopic and systemic effects of cryptorchidism are independent, then the 20% (Hogan & Johnson, 1976) (Martin, 1979).…”

“…Our findings of an association with working in a petrol station and in the printing industry are derived from responses to a check list of 15 occupations, raising the possibility that these associations, while statistically unlikely, may represent chance findings. Milham (1976) Previous studies have found that race (Ross et al, 1979;Petersen & Lee, 1973;Morrison, 1976a;Mustacchi & Millmore, 1976), socio-economic status (Davies, 1981;Graham et al, 1977;Ross et al, 1979;Petersen et al, 1977;Mustacchi & Millmore, 1976), religious affiliation (Graham et al, 1977, Morrison, 1976a) and urban-rural residence (Clemmesen, 1969;Graham et al, 1977), can all affect testicular cancer risk. Chinese people seem to experience a somewhat lower incidence than whites in the same community (I.A.R.C., 1976), although this could not be demonstrated in British Columbia.…”

“…We limit our review to studies conducted in the United States because SES levels differ across countries. Two of the four studies that evaluated the association between individual-level SES and prostate cancer incidence in the United States reported positive associations (1,2), whereas two studies reported no association (3,4). Of the seven studies that investigated area-level SES and prostate cancer incidence in the United States, three studies each reported a positive association (5)(6)(7) or no association (8)(9)(10), whereas one study reported a negative association (11).…”

PURPOSE-We investigated whether prostate cancer was associated with socioeconomic status (SES) at the individual level, area level, or a combination of both levels.METHODS-This population-based case-control study of prostate cancer in men aged 65 to 79 years was conducted between 2000 and 2002 in South Carolina. Complete interviews were available for 407 incident prostate cancer cases and 393 controls (with respective response rates of 61% and 64%). We used educational level to measure individual-level SES and a composite variable capturing income and education from 2000 Census data to measure area-level SES.RESULTS-After adjustment for race, age, geographic region, and prostate-specific antigen testing, men with some college were at reduced risk for prostate cancer (odds ratio [OR], 0.44; 95% confidence interval [CI], 0.27-0.72), as were men in the highest quartile of area-level SES (OR, 0.52; 95% CI, 0.34-0.80). When assessing individual-level and area-level SES simultaneously and accounting for their nonindependence, the independent negative associations persisted and appeared to be more striking for men with a diagnosis of localized disease, rather than advanced disease. CONCLUSION-The independent effects of area-level and individual-level SES on prostate cancer risk seen in our study may help explain the conflicting results of previous studies conducted at both levels.

Testicular cancer incidence trends in the USA (1975–2004): plateau or shifting racial paradigm?

OBJECTIVE: Plateau in testicular cancer incidence in some parts of the United States (US) especially among non-Hispanic white males in Los Angeles had been observed. We conducted three decades temporal trends analysis to assess the evidence of such a plateau, and to examine whether the rate remains stable across racial/ethnic groups as well as the influence of age at diagnosis on the incidence rate. STUDY DESIGN:Population-based temporal trends analysis. METHODS:Using the Surveillance Epidemiology and End Results (SEER), we identified between 1975 and 2004, 16,580 of newly diagnosed testicular cancer cases, aged 15−49 years. The incidence rates were examined by calculating the age-adjusted rates and their 95% Confidence Interval (CI) for the age at diagnosis, SEER areas, and race by the year of diagnosis. The percent change and annual percent change were examined for trends. RESULTS:Incidence of testicular cancer continues to increase among US males, albeit the plateau of the 1990s. Between 1975 and 2004 the age-adjusted incidence rate for ages, 15−49 years increased from 2.9 (1975) to 5.1(2004) per 100,000. The trends indicated a percent change of 71.9% and a statistically significant annual percent change of 1.6 %,( 95% CI, 1.3−2.0), p < 0.05. Though the rates in blacks remained strikingly low, 0.3 to 1.4 per 100,000, the highest annual percent change was observed among blacks, 2.3%, (95%, CI, 0.8−3.9), p < 0.05 for trends. The rates were intermediate among Asians/ Pacific Islanders and American Indian and Alaska Natives 0.7 to 2.9 per 100,000, percent change (117.3%) and a statistically significant annual change of 1.5%, (95% CI, 0.3−2.7) p < 0.05 for trends. The highest rates were reported among Whites, 3.2 to 6.3 per 100,000, percent change (90.4%) , with a statistically significant annual percent change of 2.0%, (95% CI, 1.6 −2.3), p < 0.05. The peak age at diagnosis was, 30−34 years while the lowest rates were reported in
