Late effects in survivors of teenage and young adult cancer: does age matter?

ABSTRACT

BACKGROUND: Late effects (LEs) after cancer treatment are increasing. After childhood cancer, substantial risks include physical, psychological and social LE and vary with age. Teenagers and young adults (TYA) present with particular cancers; their risk of LE may relate to cancer site, treatment or their age itself. The LEs after TYA-onset cancers are described in relation to age at diagnosis of primary tumour. PATIENTS AND METHODS: Data were extracted from Medline English language articles, 1999-2009. Keywords were late effect/s, late toxicity and survivor and the frequent TYA cancer sites. Only those articles that reported the relation between LEs risks with age at diagnosis were included. RESULTS: The majority of known LEs are described after TYA cancer. No study primarily aimed to relate TYA age to LEs. Many studies did not report LE by age. TYA-specific risks are seen in cardiac toxicity, second malignancies, pulmonary complications and psychosocial difficulties when compared with older or younger cancer survivors. CONCLUSIONS: TYA age brings specific LE risks after cancer. Prospective population-based collection of LE data after TYA cancer will inform the development of appropriate services to effectively manage LE.
