Summary
Prostate cancer is the most common cancer in Norwegian males, and the majority of men have no distant metastases at the time of diagnosis. These men are potential candidates for curative treatment with radical prostatectomy or radiotherapy. In this project we used population-based data from the Cancer Registry of Norway to investigate prognostic factors, treatment and mortality in men diagnosed with prostate cancer without distant metastases in 2001-2016.
Based on ten years observation, we found that patients were two times more likely to die from other causes than from prostate cancer (prostate cancer-specific mortality (PCSM) 8.5% vs overall mortality 25.5%), this discrepancy decreased with increasing risk group. Curative treatment reduced PCSM, and the greatest survival benefit was observed in high-risk patients. Gleason score was the strongest predictor of PCSM. After five years of observation, senior adults (>70 years) diagnosed with high-risk prostate cancer had similar prostate cancer- and overall survival benefits from curative treatment compared to younger men (<70 years). Over time, we observed an increase in the proportion of high-risk patients treated with curative intent, along with a decrease in PCSM. Both these trends were more prominent in senior men.
Increasing time to prostatectomy within six months of diagnosis did not worsen the pathological findings in the prostatectomy specimen or increase the use of post-prostatectomy radiotherapy or death from prostate cancer.
