Rising incidence trends of synchronous prostate and rectal cancers: a population-based study.

ABSTRACT:

Background

There is a lack of comprehensive reports on time trends in synchronous prostate and rectal cancers. To address this, we conducted the largest cohort study to date to assess these trends in a population-based setting.

Methods

We included all adult (ages 18-99) men with incident prostate cancer in the Swedish Cancer Register in 1993-2019. Age-standardized incidence rates (ASIRs) of prostate cancer per 100,000 male population per year were calculated and compared to the ASIR of synchronous (± 6 months from rectal cancer diagnosis) prostate cancer. Age-adjusted synchronous-to-general incidence rate ratios (IRRs) were predicted using Poisson regression. As a sensitivity analysis to assess the effect of incidental findings due to the anatomical proximity, we investigate
