Genetic and functional studies of human pain disorders have identified Na1.7, Na1.8 and Na1.9 as mediators of pain and validated them as targets for pain treatment. Voltage-gated sodium (Na) channels drive neuronal excitability and three subtypes – Na1.7, Na1.8 and Na1.9 – are preferentially expressed in the peripheral nervous system, suggesting that their inhibition might treat pain while avoiding central and cardiac adverse effects. Most common pain conditions originate in the periphery, where dorsal root ganglion and trigeminal ganglion neurons feed pain information into the CNS. Current medications used for pain management are often only partially effective, carry dose-limiting adverse effects and are potentially addictive, highlighting the need for improved therapeutic agents. The effective and safe treatment of pain is an unmet health-care need.

Theoretically grounded, multidimensional measurements of pain are absent from the literature. Fatigue was consistently associated with pain, females reported more pain than males, and other factors related to pain will require stronger evidence. The findings indicated that survivors of childhood cancer are at higher risk of experiencing pain compared with controls. Three studies investigated chronic pain according the definition in the International Classification of Diseases. Pain was present in from 4.3% to 75% of survivors across studies. Common measures of pain were items created by the authors for the purpose of the study (45.2%) or health-related quality-of-life/health status questionnaires (42.5%). The quality of evidence was evaluated according to Grading of Recommendations Assessment Development and Evaluation (GRADE) criteria. Risk of bias was considered using the Cochrane risk of bias tool. Seventy-three articles were included in the final review. Eligible studies included: 1) original research, 2) quantitative assessments of pain, 3) articles published in English, 4) cancers diagnosed between birth and age 21 years, 5) survivors at 5 years from diagnosis and/or at 2 years after therapy completion, and 6) a sample size >20. Data sources for the study were articles published from January 1990 to August 2019 identified in the PubMed, PsycINFO, EMBASE, and Web of Science data bases. The objective of this study was to describe: 1) the prevalence of pain in survivors of childhood cancer, 2) methods of pain measurement, 3) associations between pain and biopsychosocial factors, and 4) recommendations for future research. Survivors of childhood cancer may be at risk of experiencing pain, and a systematic review would advance our understanding of pain in this population.
