Objective:
To summarise the evidence on the effect of psychological coping styles (including fighting spirit,
helplessness/hopelessness, denial, and avoidance) on survival and
recurrence in patients with cancer.
What is already known on this topic
Some studies have shown that a coping style involving fighting spirit
rather than helplessness/hopelessness is associated with survival and
recurrence, though the evidence is inconsistent What this study adds
Publication bias and methodological flaws in some of the primary
studies may explain some of the previous positive findings There is no good evidence to support the development of psychological
interventions to promote particular types of coping in an attempt to
prolong survival
Design:
Systematic review of published and
unpublished prospective observational studies.
Main outcome measures:
Survival from or recurrence of cancer.
Results:
26 studies investigated the association
between psychological coping styles and survival from cancer, and 11 studies investigated recurrence. Most of the studies that investigated fighting spirit (10 studies) or helplessness/hopelessness (12 studies)
found no significant associations with survival or recurrence. The
evidence that other coping styles play an important part was also weak.
Positive findings tended to be confined to small or methodologically
flawed studies; lack of adjustment for potential confounding variables
was common. Positive conclusions seemed to be more commonly reported by
smaller studies, indicating potential publication bias.
Conclusion:
There is little consistent evidence that
psychological coping styles play an important part in survival from or
recurrence of cancer. People with cancer should not feel pressured into
adopting particular coping styles to improve survival or reduce the
risk of recurrence.
Survival from cancer is commonly thought to be influenced by a
person's psychological coping style
This systematic review suggests that there is no consistent association
between psychological coping and outcome of cancer
