- Patients with mental illness are significantly less likely to receive cancer screenings than those without mental illness, especially women with schizophrenia, according to a meta-analysis that included 4.5 million people in all continents except Africa.
Why this matters
- People with mental illness have a greater risk for cancer-related death compared with those without mental illness.
- A meta-analysis of 46 studies focusing on any type of cancer screening in patients with mental illness (patients with mental illness, n=501,559; control individuals, n=4,216,280).
- Funding: None.
- Median quality of studies: 7 (interquartile range, 6-8).
- Disparities in cancer screening were noted in patients with mental illness vs control patients (P<.001 style="list-style-type:circle;">
- any cancer: OR, 0.76;
- breast cancer: OR, 0.65;
- cervical cancer: OR, 0.89; and
- prostate cancer: OR, 0.78.
- any cancer: OR, 0.62 (P<.001>
- breast cancer: OR, 0.52 (P<.001 and>
- cervical cancer: OR, 0.75 (P=.010).
- less likely for any (OR, 0.85) and breast (OR, 0.77; P both<.001 cancer>
- more likely for colorectal cancer (OR, 1.18; P=.036).
- Findings should be interpreted with caution.
