Childhood cancer survivors are at risk of developing primary recurrences and new second cancers. Experiencing a recurrence and/or second cancer can be highly distressing for survivors and families. We aimed to understand the psychological impacts of experiencing a recurrence or second cancer and how this potentially influences survivors’ engagement with survivorship care.

We invited childhood cancer survivors or their parents if survivors were ≤16 years of age from 11 tertiary pediatric oncology hospitals across Australia and New Zealand to complete interviews. We conducted a thematic analysis facilitated by NVivo12.

We interviewed 21 participants of whom 16 had experienced a recurrence, 3 had a second cancer, and 2 had both a recurrence and second cancer. Participants reported that a recurrence/second cancer was a stressful sudden disruption to life, accompanied by strong feelings of uncertainty. Participants tended to be less aware of their second cancer risk than recurrence risk. Some participants reported feelings of anxiousness and despair, describing varying responses such as gratitude or avoidance. Participants shared that the fear of cancer recurrence either motivated them to adopt protective health behaviors or to avoid information and disengage from survivorship care.

Some survivors and their parents have a poor understanding and expressed reluctance to receive information about their risk of second cancer and other treatment-related late effects. Improving the delivery of information about late effects to families may improve their engagement with survivorship care and surveillance, although care must be taken to balance information provision and survivors’ anxieties about their future health.
