Abstract

Background.Previous studies of the association between social and family status and prostate cancer (PCa) have given somewhat divergent results. Little attention has been paid to the possible importance of these factors for survival.

Methods.In this study, hazard regression models for PCa incidence and mortality were estimated on the basis of register- and census-based histories for complete Norwegian birth cohorts, giving a follow-up time of 16 million person years and 30,000 cases of PCa.

Results.A significant excess incidence of about 20% was found for ever-married men and for those with higher education. Marriage and socioeconomic resources appeared, however, to have a favorable effect on survival. Five-year relative survival from metastasized cancer among men with a high educational level was found to be 15 percentage points higher than among men with lower education.

Conclusions.The observed differences in incidence are not easily explained. They apparently run counter to the hypothesis that multiple partners give a higher PCa risk, but may be consistent with the view that fat and meat consumption is risky. Better survival from PCa in higher socioeconomic groups and among married men may reflect differences in the search for, access to, or quality of treatment or a better constitution to fight the disease.

      For example, the effect of a high mean age on the diagnosis of thyroid cancer is present in a large number of widowed and divorced patients.24 Furthermore, married patients are considered to have better financial status, social support, housing, lifestyle, and access to healthcare.25 Moreover, it has been observed that SES disparities have a huge impact on the difference in healthcare quality and accessibility.6,26,27

      They found complex relationships between SES and PC incidence, treatment, and outcomes [5,11,18]. While some studies found no association between SES and PC incidence, others linked increased education and income with increased risk, or lower income with increased risk of distant-stage PC and worse PCSM [8,9,17,19,20]. This may be explained by access to care and screening in some settings, but does not explain our findings that low SES black men are less likely to experience CRPC, metastasis, and PCSM than low SES white men.

      Despite knowledge of these racial disparities, further work and intervention are required to improve these outcomes.7,8 The role of marital status has been well established as a prognostic factor for cancer patients including bladder cancer.23-26 Compared to unmarried patients, married patients have improved outcomes and are less likely to present with advanced disease.10,23,27

      Citation Excerpt :

      Perceived barriers to care and perceptions and attitudes toward participatory decision making are unfavourably affected by lower health literacy (Yin et al., 2012). Furthermore, psychosocial factors like being married were shown to improve survival significantly after prostate cancer diagnosis and should additionally be taken into account when analysing disparities (Harvei and Kravdal, 1997; Kravdal, 2013a, 2001). And, although lifestyle behaviour plays a minor role in the reviewed studies, it could also be relevant for further analyses.
