Outcomes of adolescents with acute lymphoblastic leukaemia.

INTRODUCTION: Compared with young children who have acute lymphoblastic leukaemia (ALL), adolescents with ALL have unfavourable disease profiles and worse survival. However, limited data are available regarding the characteristics and outcomes of adolescents with ALL who underwent treatment in clinical trials. The aim of this study was to investigate the causes of treatment failure in adolescents with ALL. METHODS: We retrospectively analysed the outcomes of 711 children with ALL, aged 1-18 years, who were enrolled in five clinical trials of paediatric ALL treatment between 1993 and 2015. RESULTS: Among the 711 children with ALL, 530 were young children (1-9 years at diagnosis) and 181 were adolescents (including 136 younger adolescents [10-14 years] and 45 older adolescents [15-18 years]). Compared with young children who had ALL, adolescents with ALL were less likely to have favourable genetic features and more likely to demonstrate poor early response to treatment. The 10-year overall survival and event-free survival rates were significantly lower among adolescents than among young children (77.9% vs 87.6%, P=0.0003; 69.7% vs 76.5%, P=0.0117). There were no significant differences in the 10-year cumulative incidence of relapse, but the 10-year cumulative incidence of treatment-related death (TRD) was significantly greater among adolescents (7.2%) than among young children (2.3%; P=0.002). Multivariable analysis showed that both younger and older adolescents (vs young children) had worse survival and greater incidence of TRD. CONCLUSION: Adolescents with ALL had worse survival because they experienced a greater incidence of TRD. There is a need to investigate optimal treatment adjustments and novel targeted agents to achieve better survival rates (without excessive toxicity) among adolescents with ALL.

Sexual function, self-esteem, and general well-being in Chinese adult survivors of childhood cancers: a cross-sectional survey.

INTRODUCTION: This study was conducted to evaluate sexual function in adult survivors of childhood cancers and investigate possible relationships between sexual function and quality of life, as measured by general well-being, self-esteem, body image, and depressive symptoms. METHODS: This cross-sectional survey was performed in our centre from 14 August 2015 to 8 September 2017. Adult patients who had a history of childhood cancers, and who were disease-free for >3 years, were approached for the study during clinical follow-up. Clinical information was collected from medical records. Self-administered questionnaires regarding quality of life and sexual functioning were given to the patients and resulting data were analysed. RESULTS: Two hundred patients agreed to participate in the study. The overall response rate was 64.8%. Ninety-one (45.5%) patients were women, and the mean age was 25.4 ± 5.57 years. The overall sexual functioning score was 28.3 ± 20.09. Forty-eight (24.0%) patients reported at least one sexual problem. Among patients who reported no sexual problems, more had haematological cancers (P=0.009), fewer underwent surgery (P=0.004), fewer underwent surgery with external effects (P=0.032), and fewer were regular social drinkers (P=0.013); additionally, they had a higher mean Rosenberg self-esteem scale score (P=0.010), lower mean body image scale score (P=0.008), and lower mean Patient Health Questionnaire score (P=0.001). CONCLUSION: Aspects of life beyond disease condition and physical function should be considered in adult survivors of childhood cancers. Appropriate referral and intervention should be initiated for these patients when necessary.
