Abstract

PURPOSE:

Research to date on fear of cancer recurrence (FCR) shows that moderate to high FCR affects 22-87 % of cancer survivors and is associated with higher psychological morbidity (Simard et al J Cancer Surviv 7:300-322, 2013). Despite growing research interest in FCR, the lack of consensus on its definition and characteristics when it reaches a clinical level has impeded knowledge transfer into patient services.

METHODS:

In order to address these gaps, expert researchers, policy makers, trainees, and patient advocates attended a 2-day colloquium at the University of Ottawa in August 2015. A Delphi method was used to identify the most relevant definition of FCR, and the attendees generated possible diagnostic characteristics of clinical FCR.

RESULTS:

After three rounds of discussion and voting, the attendees reached consensus on a new definition of FCR: "Fear, worry, or concern relating to the possibility that cancer will come back or progress." Regarding clinical FCR, five possible characteristics were proposed: (1) high levels of preoccupation, worry, rumination, or intrusive thoughts; (2) maladaptive coping; (3) functional impairments; (4) excessive distress; and (5) difficulties making plans for the future.

CONCLUSIONS:

The new proposed definition of FCR reflects the broad spectrum in which patients experience FCR. A consensual definition of FCR and the identification of the essential characteristics of clinical FCR are necessary to accurately and consistently measure FCR severity and to develop effective interventions to treat FCR. We hope this broad definition can encourage further research and the development of inclusive policies for all cancer patients and survivors who are struggling with this issue.
