Examining the relationship between multiple primary cancers and psychological distress: A review of current literature.

There is a substantial lack of evidence focused on psychological distress among the growing MPC survivor population. ES noted in the 5 studies reflect small but potentially significant increases in psychological distress in survivors of MPC compared with survivors of a single cancer. Clinicians should be aware of this at-risk population when screening for distress in cancer survivors. Suggestions for future research are provided.
