Posttraumatic growth: a novel concept in oral cavity cancer care?

Recently the importance of posttraumatic growth (PTG), a phenomenon of positive psychological growth beyond baseline values, has been discovered in the field of oncology. An evidence based review of the literature regarding PTG was performed, both to support its understanding and to consider its application within the research field of oral cavity (OC) cancer. A Pubmed, Medline, PsycINFO search from the earliest date until April 2010 was carried out. Full articles meeting the inclusion and exclusion criteria were reviewed. The search yielded 852 papers, 91 'potentially relevant papers' and 29 'effective papers', the latter of which formed the basis of this review. PTG was assessed in twenty-eight studies with the Posttraumatic Growth Inventory and in only one study with the Perceived Benefits Scale (PBS). PTG in cancer patients has been reported in five main domains (i) appreciation of life, (ii) relating to others, (iii) increased personal sense, (iv) sense of new possibilities and (v) positive spiritual change. Socio-demographic factors, stressor characteristics and coping strategies influence and predict the development PTG. In the past decade an increasing interest in the concept of PTG in the field of oncology has emerged. This evidence based review presents PTG to the research community in the field of OC cancer, appraises its modification capacity of the treatment outcome in other cancer research fields and hypothesizes its eventual benefit in the field of OC cancer research.
