TOPLINE:
Spouses of patients with cancer face a significantly higher risk for suicide attempts and deaths, especially within the first year after their spouse is diagnosed with cancer, according to an analysis based in Denmark.
METHODOLOGY:
- A growing body of evidence has revealed higher levels of psychological distress and an increased risk for psychiatric disorders among spouses of patients with cancer, but less is known about suicidal behaviors among spouses.
- In a recent analysis, researchers assessed the risk for suicide attempts and suicide deaths among the spouses of patients with cancer in a nationwide cohort based in Denmark.
- Researchers collected registry-based data from 1986 to 2016, comparing suicide attempts and deaths between individuals with a spouse diagnosed with cancer and those without. Suicide attempts were identified through The Danish National Patient Register and The Danish Psychiatric Central Research Register, and suicide deaths were identified through The Danish Register of Causes of Death.
- A total of 409,338 spouses of patients with cancer (exposed group) were compared with 2,046,682 matched control participants (unexposed group). The participants were followed from cohort entry until a first suicide attempt, suicide death, death from other causes, emigration, or December 31, 2016, whichever came first.
TAKEAWAY:
- Spouses of patients with cancer had an increased risk for suicide attempts (hazard ratio [HR], 1.28) and suicide deaths (HR, 1.47), especially within the first year after a cancer diagnosis (HR for attempts, 1.45; HR for deaths, 2.56).
- The increased risk for suicide attempts was more pronounced among men (HR, 1.42), those with a lower household income (HR, 1.39), and those with a history of cancer themselves (HR, 1.57).
- Among those who attempted suicide, researchers observed positive associations for most, but not all, cancer types and for cancers diagnosed at regional spread or an advanced stage (HR, 1.66) or an unknown stage (HR, 1.28), as well as following the death of the spouse to cancer (HR, 1.57).
- Researchers also observed an increased risk for suicide death for most, but not all, cancer types and greater increases for cancers diagnosed at more advanced stages (HR, 1.61) or unknown stages (HR, 1.52), as well as following the spouse’s death (HR, 1.70).
IN PRACTICE:
“To our knowledge, this nationwide cohort study is the first to show that spouses of patients with cancer have an elevated risk of both suicide attempt and suicide death,” the authors concluded. “These findings suggest a need for clinical and societal awareness to prevent suicidal behaviors among spouses of patients with cancer, particularly during the first year following the cancer diagnosis.”
In an accompanying editorial, experts noted that “the mental health impacts may well be higher in countries that have more restricted healthcare access,” given that Denmark has universal healthcare. The editorialists also noted the “pressing need to integrate spousal health more fully into cancer survivorship care.
“Psychosocial distress should no longer be a hidden and unaddressed cause of suffering in spouses of patients with cancer,” they wrote.

The study, led by Qianwei Liu, MD, PhD, Institute of Environmental Medicine, Karolinska Institutet in Stockholm, Sweden, and the accompanying editorial were published online in JAMA Oncology.
LIMITATIONS:
Residual confounding was one potential limitation, though the researchers tried to control for several important confounders. The result may not be generalizable to other countries with different healthcare systems, cultural contexts, or burdens of cancer and suicidal behaviors.
DISCLOSURES:
One coauthor reported receiving grants from Forte during the conduct of the study. Another coauthor
disclosed receiving grants from the Swedish Cancer Society. Additional disclosures are noted in the original article.
