To investigate whether men with biopsy-verified low-grade cancer and a family history of lethal or advanced prostate cancer are at particularly high risk of harboring undetected high-grade disease.
Upgrading and upstaging of prostate cancer is common after prostatectomy. In a nationwide population-based cohort, we identified 6 854 men with low-risk prostate cancer who underwent radical prostatectomy. Among them, 1 739 (25%) had a history of prostate cancer among a first-degree relative, and 289 (4%) had a first degree relative with lethal or advanced prostate cancer.
Compared with men with no familial occurrence of prostate cancer, the odds ratio (OR) for the risk of upstaging among men with a familial occurrence of high-risk or lethal prostate cancer was 1.06 (95% CI, 0.76-1.47). The corresponding OR for upgrading was 1.17 (0.91-1.50).
We found no association between family history of prostate cancer and upstaging or upgrading after radical prostatectomy.
