Adolescent and young adult (AYA) survivors of childhood cancers: A challenge in after completion of therapy (ACT) clinic in resource-constrained country.

Abstract

19 Background: To assess the evaluation of late effects in childhood cancer survivors who have transitioned to AYA age group on longitudinal follow up in After Completion of Therapy (ACT) clinic at Tata Memorial Hospital, Mumbai. Methods: ACT clinic database was analyzed for childhood cancer survivors who have attained age 15-30 yrs at last follow up in the clinic for demographics, grade of late effects &pattern of follow up. Results: Of 1720 childhood cancer Survivors ( > , 2 yrs off therapy & disease free) registered in ACT clinic from Feb 91-Feb15, 976(56.7%) are in AYA group, M.F = 707/269 (2.6:1), Hematolymphoid : Solid tumours = 543/433 (1.3:1), Mumbai based: Non Mumbai = 306/670 (1:2.2).Median age at diagnosis 8 yrs, current median age 20 yrs, median duration of ACT clinic follow up is 6 yrs. At registration 448 (47%) had no late effects. 230(24%) had grade I, 81(8.4%) grade II 195 (20%) had grade III. Only 9(1%) had grade IV late effects which increased to 53 (6%) at last follow up due to recurrence & second neoplasia. Only 29(3%) were at low risk of developing potential late effects. 466(48.5%) were in intermediate risk & 48.5% (466) fell in high risk category requiring at least annual follow up. 72% of survivors registered in ACT clinic from 1991-2001 had stopped follow up as compared to 36% registered in subsequent decade (p < 0.01). Conclusions: AYA survivors of childhood cancers form major (56.7%) group in Long Term Follow up clinic. The increasing incidence of life threatening late effects on longitudinal follow up combined with statistically significant increasing trend of stopping follow up over period of time since ACT registration is alarming & calls for innovative approaches for maintaining good follow up through survivor centric approaches such as use of IT based communication technologies & formation of childhood cancer survivors support groups like Ugam.
