Second cancers after childhood cancer – GPs beware!

Abstract

BackgroundOne of the long-term effects in childhood cancer survivors (CCS) is the development of second cancers. In a cohort of CCS, this study describes how second cancers were presented, the way they were diagnosed, and the knowledge CCS had about their increased risk to develop a second cancer.Patients and methodsSelected participants were all adult five-year CCS (n = 1275) who were treated at the University Medical Center Groningen since 1965. Of these, 84 (6.6%) had developed a second cancer, of which 27 had died. The 57 survivors were asked to participate in a telephone interview.ResultsOf the 57 CCS, 35 (61%) participated. Together they had developed 45 second cancers. Most participants (97%) were seen at the long-term follow-up clinic. Of all second cancers, 89% caused symptoms. Of all second cancers, the majority (56%) were first presented at the general practitioner's (GP's) office and 20% at follow-up testing. Of these CCS, only 28% were aware of their increased risk of developing a second cancer.ConclusionsIt is important to inform CCS continuously regarding their increased risk, as a relatively small percentage are aware of this. Since most of these patients first reported their symptoms to the GP, all GPs should be aware of this increased risk, in particular because this concerns cancer at a younger age than normally expected. A survivor care plan might be an effective way of communication with both CCS and GPs.

Effects of Exercise Interventions on Immune Function in Children and Adolescents With Cancer and HSCT Recipients - A Systematic Review

“…Children and adolescents with cancer are at high risk for life-threatening infections and therapy associated complications. They further have a risk for disease recurrence or development of secondary malignancies ( 1 , 2 ). Thus, interventions are needed to decrease the probability of cancer-related side effects and increase the patients’ quality of life.…”

Current childhood cancer survivor long-term follow-up practices in South Africa

“…A similar trend exists for limited knowledge regarding the risk of developing a second malignant neoplasm. Less than a third of childhood cancer survivors (28%) who were treated at the Groningen University Medical Centre were aware of their risk of a second malignant neoplasm (SMN) [44]. It is important to discuss this risk factor with patients and their families, as their LTFU programme should be adjusted based on the individual risk for an SMN.…”

Creation of gastric conduit free-graft with intraoperative perfusion imaging during pancreaticoduodenectomy in a patient post esophagectomy

“…Recent advances in gastrointestinal cancer diagnosis and treatment have resulted in improved survival. On top of other individual risk factors, long term effects of chemo-radiation increases the risk of developing a second malignancy [1] . Increased number of reports of patients who survived long enough to develop a second malignancy can be found in the literature.…”
