    Schizophrenia Linked to Early Death

    Suicide, Cancer, Heart Disease Leading Causes of Death in Schizophrenics

    June 22, 2009 -- The mortality rate among schizophrenics is four times higher than in the general population, with suicide being the No. 1 cause of death, followed by cancer, according to a new study.

    Deaths from cancer among women with schizophrenia were twice that of the general population, based on standardized mortality data. Deaths from breast cancer were almost three times higher than expected. The study appears in the Aug. 1 issue of Cancer.

    Lung cancer death rates among male schizophrenics were about twice that of men in the general population, but the overall risk of dying from cancer was not significantly different between the two groups.

    It has long been recognized that schizophrenia is associated with a higher risk for suicide and death from heart disease, but the investigation is one of the largest and longest follow-up studies to explore cancer deaths in schizophrenic patients.

    Schizophrenics are more likely to smoke than the general population, and are less likely to have comprehensive medical care.

    They may also be more likely to have a delayed cancer diagnosis, have poorer access to treatment, or be noncompliant with treatment, lead investigator Frederic Limosin, MD, PhD, of France's University of Reims tells WebMD.

    "Cancer is the second leading cause of death in schizophrenic patients," Limosin says. "Later diagnosis and treatment issues may explain this, but there may also be something else going on."

    Schizophrenia Linked to Early Death

    The study included 3,470 French patients with schizophrenia followed for 11 years between 1993 and 2004.

    Patients ranged in age from 18 to 64 at study entry. About two-thirds were between the ages of 39 and 64 at enrollment.

    During the follow-up, 476 patients (14%) died -- a death rate that was fourfold higher than in the age-matched general population.

    The study revealed that:

    • The death rate from suicide was more than 15 times higher than that of the general population, Limosin says.
    • A total of 143 patients committed suicide (4.2%), compared to 74 who died from cancer (2.2%), and 70 from cardiovascular disease (2%).
    • Half of the malignancy-related deaths in men in the study were attributed to lung cancer, and about 40% of the cancer deaths in women were from breast cancer.
