Abstract [en]

Accumulating evidence suggest that Propionibacterium acnes may play a role in prostate carcinogenesis, but data are so far limited and inconclusive. The aim of this population-based cohort study was therefore to test whether presence of acne vulgaris during late adolescence is associated with an increased risk of prostate cancer later in life. We identified a large cohort of young men born in Sweden between 1952 and 1956, who underwent mandatory assessment for military conscription around the age of 18 (n= 243,187). Test information along with health data including medical diagnoses at time of conscription was available through the Swedish Military Conscription Register and the National Patient Register. The cohort was followed through linkages to the Swedish Cancer Register to identify the occurrence of prostate cancer until December 31st 2009. We used Cox regression to calculate adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) for the association between acne in adolescence and prostate cancer risk. A total of 1,633 men were diagnosed with prostate cancer during a median follow-up of 36.7 years. A diagnosis of acne was associated with a statistically significant increased risk for prostate cancer (adjusted HR: 1.43 95%; CI: 1.06-1.92), particularly for advanced stage disease (HR: 2.37 95%; CI 1.19-4.73). A diagnosis of acne classified as severe conferred a 6-fold increased risk of prostate cancer (HR: 5.70 95% CI 1.42-22.85). Data from this large prospective population-based cohort add new evidence supporting a role of P acnes infection in prostate cancer.

Abstract [en]

Chronic inflammation has been implicated in the development of several types of cancer, and evidence from observational and animal studies suggests that it may play a role also in prostate carcinogenesis. Recent observations have brought Cutibacterium acnes (C. acnes) forward as a possible causative agent in pro-oncogenic prostatic inflammation. However, evidence also suggest that underlying immune characteristics contribute to prostate cancer risk. The overall aim of this thesis was to explore potential mechanisms underlying the proposed link between inflammation and prostate cancer, by evaluating associations between inflammatory conditions during early adulthood, circulating inflammation markers, and prostate cancer. Due to the suggested role of C. acnes in both diseases, we aimed to investigate whether acne vulgaris is a determinant of prostate cancer. Using prospectively collected data from Swedish national registers, we observed that presence of acne during early adulthood conferred an increased risk of prostate cancer later in life. Similarly, we found that appendicitis before late adolescence – a proposed marker of individual immune characteristics – to be positively associated with subsequent prostate cancer. We further evaluated whether prostatic C. acnes infection is linked with elevated systemic levels of IL6 and CXCL8, two inflammation markers previously associated with prostate cancer. No association was observed, however, potentially explained by the subclinical low-grade infection typically caused by C. acnes. Finally, we evaluated 52 circulating inflammation markers as determinants for prostate cancer in a population-based case-control study. In this hypothesis-generating study, we identified CX3CL1, CCL21, PDGF-BB, CCL11 and IL10 as candidate markers for evaluation in prospective studies. If confirmed, these markers may hint at targetable molecular pathways involved in prostate carcinogenesis.
