Psychosocial processes and cancer incidence among Japanese men in Hawaii

Effects of psychotherapy on cancer survival

The possibility that psychotherapy could extend survival time for cancer patients has attracted attention among clinical investigators interested in the mind-body connection, among cancer patients seeking the best possible outcome and among the general public. A small number of randomized trials have been conducted, and they have produced conflicting results. Does emotional support affect the course of cancer? What physiological pathways might mediate such an effect? Given what we now know, should we change the standard of care for cancer patients?

Emotional states and physical health

Positive emotional states may promote healthy perceptions, beliefs, and physical well-being itself. To explore potential mechanisms linking pleasant feelings and good health, the authors consider several lines of research, including (a) direct effects of positive affect on physiology, especially the immune system, (b) the information value of emotional experiences, (c) the psychological resources engendered by positive feeling states, (d) the ways in which mood can motivate health-relevant behaviors, and (e) the elicitation of social support. As anticipated by the Greek physician Hippocrates, positive emotions and healthy outcomes may be linked through multiple pathways.

Improving the quality and quantity of life among patients with cancer: a review of the effectiveness of group psychotherapy

Cancer patients suffer from a number of psychosocial problems related to the progression of their disease as well as standard medical interventions. Fortunately, there is empirical evidence suggesting that group psychotherapy is effective at ameliorating psychological distress and in some cases improving survival. For this literature review we examined the psychological morbidity, particularly anxiety and depression, among cancer patients. Further, we conducted a critical examination of the current evidence regarding the effectiveness of group psychotherapy for improving the quality as well as the quantity of life in cancer patients. Finally, we explored the specific components of effective group psychotherapy, which has been associated with enhanced survival. We conclude that there is compelling evidence indicating that group psychotherapy improves the quality of life of cancer patients. Furthermore, there is a growing body of evidence suggesting that group psychotherapy improves survival of cancer patients.
