Post-traumatic growth 5 years after cancer: identification of associated actionable factors

Background The number of cancer survivors is growing increasingly worldwide. The long-term negative consequences of the disease are now better known. Cancer may also foster positive outcomes. Some survivors consider life after cancer as the start of a new life and experience positive changes called post-traumatic growth (PTG) measured by a scale developed by Tedeschi and Calhoun. Objective The purpose of this article was to explore actionable factors affecting PTG, particularly those in relation with health care management and those that reflected health behavior changes. Methods This study included the 1,982 participants in the VICAN cohort who responded to the questionnaire on living conditions 2 and 5 years after diagnosis. Factors associated with a moderate or high PTG (score ≥ 63) were identified using logistic regressions. Results Factors positively associated with moderate or high PTG were being satisfied with the time spent by health care team on information (OR:1.35 [1.08;1.70]), increased physical activity (OR:1.42 [1.04;1.95]) and healthier diet (OR:1.85 [1.44;2.36]) since diagnosis, and having benefited from psychological support at diagnosis (OR:1.53 [1.16;2.01]). Conclusion High PTG is positively associated with health behavior and time spent on information. Our findings suggest that appropriate clinical and educational interventions can help foster growth after the experience of cancer. Even if we do not know what causes what, it is admitted that the interventions leading to an increase of physical activity, for example, are good from all points of view.
