Surviving Prostate Cancer Yet Thinking About Suicide

We need to know more about the factors that contribute to this suicide risk.

Background
Cancer survivors have been shown to be more likely to have suicidal ideation than their same age peers. Prostate cancer survivors share this risk. They are also typically over 65, which puts them in an age group with increased risk for suicide.

The Study
Dr. Christopher Recklitis surveyed prostate cancer (PC) survivors who were first diagnosed 3 to 8 years before the study.

The survey asked survivors about suicidal ideation, depressed mood, suicidal ideation and demographic characteristics. The survey also inquired about pain, health-related quality of life, lifetime and recent recurrence, as well as the use of health services in the past 12 months.

The survey included:

  • The 26-item Expanded Cancer Index Composite Instrument (EPIC-26) about symptoms and PC treatment.
  • The Short-form 12 (SF-12).
  • The Beck Depression Inventory.
  • The Geriatric Depression Inventory.

Results
The response to the survey was impressive, with 693 of 979 men completing the questionnaires.

  • Over 12% of men reported some suicidal ideation, with 5.2% reporting active suicidal ideation and 1.4% reporting serious suicidal ideation—all higher levels than peers without cancer.
  • Emotional and physical health, unemployment, pain, low income, and depressed mood (not clinically significant depression) were associated with suicidal ideation.
  • Having a previous mental health condition related to suicidal ideation.
  • Age, type of cancer treatment, time since cancer diagnosis, cancer recurrence, and other treatment factors were not related to suicidal ideation.

Takeaway
While most men fare well, some men with PC are at long-term risk for emotional and physical discomfort. Physicians should check in with patients about their pain (physical and emotional), address concerns about side effects and mood, and assess for suicidal ideation using several questions about different periods of time. For patients with pervious mental health conditions, a PC cancer diagnosis may increase their risk and extra attention may need to be given for their care and support.
