USA: In a new study led by Matthew B. Clements, it was found that men with biopsy indications and a family history of prostate or breast cancer are more likely to develop high-grade prostate cancer, regardless of other risk factors. The findings of this study were published in the journal European Urology on 31st December 2021.
The general risk of high-grade prostate cancer in males with a cancer family history has been documented in the general population, but not in individuals chosen for a prostate biopsy in an international cohort. As a result, the goal of this study was to assess the probability of high-grade prostate cancer on biopsy based on a family history of cancer.
This was a multicenter study of males receiving prostate biopsy from 2006 to 2019, with 12 facilities in North America and Europe participating. All sites collected first-degree prostate cancer family histories; four also collected more extensive information on the number of afflicted relatives, second-degree relatives with prostate cancer, and breast cancer family history. The probabilities of having high-grade (Gleason grading group 2) prostate cancer was assessed using multivariable logistic regressions. Family history definitions, such as first- and second-degree prostate cancer and breast cancer family histories, were fit to separate models.
The key findings of this study were as follow:
1. For 15 799 males, a first-degree prostate cancer family history was available, with a more thorough family history available for 4617.
2. The adjusted odds of having high-grade prostate cancer were 1.77 times higher with first-degree prostate cancer, 1.38 with second-degree prostate cancer, and 1.30 with first-degree breast Interaction terms demonstrated that the influence of a family history varies dependent on age rather than prostate-specific antigen.
In conclusion, positive family history is regarded as a well-established risk factor for a variety of malignancies. When a first-degree relative is diagnosed with prostate cancer, the lifetime chance of developing the illness increases by two to triple.
