Thinking about one's own death after prostate-cancer diagnosis

Prostate-cancer diagnosis increases the risk for psychiatric morbidity and suicide. Thoughts about one's own death could indicate need for psychiatric care among men with localized prostate cancer. We studied the prevalence and predictors of thoughts about own death among men with prostate cancer.

Of the 3930 men in the prospective, multi-centre LAPPRO-trial, having radical prostatectomy, 3154 (80%) answered two study-specific questionnaires, before and three months after surgery. Multivariable prognostic models were built with stepwise regression and Bayesian Model Averaging.

After surgery 46% had thoughts about their own death. Extra-prostatic tumor-growth [Adjusted Odds-Ratio 2.06, 95% Confidence Interval 1.66-2.56], university education [OR 1.66, CI 1.35-2.05], uncertainty [OR 2.20, CI 1.73-2.82], low control [OR 2.21, CI 1.68-2.91], loneliness [OR 1.75, CI 1.30-2.35], being a burden [OR 1.59, CI 1.23-2.07], and crying [OR 1.55, CI 1.23-1.96] before surgery predicted thoughts about one's own death after surgery.

We identified predictors for thoughts about one's own death after prostate cancer diagnosis and surgery. These factors may facilitate the identification of psychiatric morbidity and those who might benefit from psychosocial support already during primary treatment.
