[Clinical efficacy of combined therapy in children with stage 4 neuroblastoma]. / 儿童4期神经母细胞瘤联合治疗的临床疗效观察.

OBJECTIVES: To study the early clinical efficacy of combined therapy of stage 4 neuroblastoma. METHODS: A retrospective analysis was performed on the medical data and follow-up data of 14 children with stage 4 neuroblastoma who were diagnosed in Hong Kong University-Shenzhen Hospital from January 2016 to June 2021. RESULTS: The median age of onset was 3 years and 7.5 months in these 14 children. Among these children, 9 had positive results of bone marrow biopsy, 4 had N-Myc gene amplification, 13 had an increase in neuron-specific enolase, and 7 had an increase in vanilmandelic acid in urine. Based on the results of pathological examination, differentiated type was observed in 6 children, undifferentiated type in one child, mixed type, in one child and poorly differentiated type in 6 children. Of all the children, 10 received chemotherapy with the N7 regimen (including 2 children receiving arsenic trioxide in addition) and 4 received chemotherapy with the Rapid COJEC regimen. Thirteen children underwent surgery, 14 received hematopoietic stem cell transplantation, and 10 received radiotherapy. A total of 8 children received Ch14.18/CHO immunotherapy, among whom 1 child discontinued due to anaphylactic shock during immunotherapy, and the other 7 children completed Ch14.18/CHO treatment without serious adverse events, among whom 1 child was treated with Lu177 Dotatate 3 times after recurrence and is still undergoing chemotherapy at present. The median follow-up time was 45 months for all the 14 children. Four children experienced recurrence within 2 years, and the 2-year overall survival rate was 100%; 4 children experienced recurrence within 3 years, and 7 achieved disease-free survival within 3 years. CONCLUSIONS: Multidisciplinary combined therapy is recommended for children with stage 4 neuroblastoma and can help them achieve better survival and prognosis.

Factors contributing to the low physical activity level for Hong Kong Chinese children hospitalised with cancer: an exploratory study.

AIMS AND OBJECTIVES: To explore the factors contributing to the low physical activity level for Hong Kong Chinese children hospitalised with cancer. BACKGROUND: Notwithstanding the fact that regular physical activity can ameliorate cancer-related fatigue and other adverse effect of cancer treatment on children's physical and psychological well-being, physical inactivity is a common problem among children undergoing cancer treatment. Understanding the factors that affect their physical activity level is an important step towards planning and evaluating an appropriate intervention that promotes the adoption and maintenance of regular physical activity. DESIGN: A phenomenological design was used in this qualitative study. METHODS: A purposive sample of 25 children with cancer was recruited in a paediatric oncology unit of an acute care public hospital in Hong Kong. They were asked to participate in a semistructured interview by their bedside lasting about 30 minutes. All the interviews were tape-recorded and immediately transcribed. Content analysis was used to analyse the qualitative data. RESULTS: The findings revealed that the patients' physical condition, misunderstanding about physical activity by children, parents and healthcare professionals, emotional disturbances and social influences are four important factors impeding children from engaging in regular physical activity during cancer treatment. CONCLUSION: This study addresses a gap in the literature by identifying the factors that negatively influence the physical activity levels of Hong Kong Chinese children hospitalised with cancer. RELEVANCE TO CLINICAL PRACTICE: Understanding these factors, nurses can explore interventions that target on correcting the misunderstanding and providing relevant information about the importance of physical activity, eventually promoting the adoption and maintenance of regular physical activity and enhancing the quality of life.

Psychometric properties of the Chinese version of the fatigue scale-adolescent.

BACKGROUND: The availability of a valid and reliable instrument that accurately assesses the level of fatigue among adolescent cancer survivors is crucial before any appropriate interventions to reduce their fatigue can be appropriately planned and evaluated. The study aimed to test the psychometric properties of the Chinese version of the Fatigue Scale for Adolescents. In particular, confirmatory factor analysis was conducted to examine its factorial structure. METHODS: A cross-sectional study was employed. Adolescents (13- to 18-year-olds) who had survived cancer and attended medical follow-up at the outpatient clinic in Hong Kong were invited to participate. The internal consistency, content validity and construct validity and test-retest reliability of the Chinese version of the Fatigue Scale for Adolescents were assessed. RESULTS: The content validity index was 0.92. There was a strong positive correlation between adolescents' levels of fatigue and depressive symptoms (r = 0.53) and a strong negative correlation between adolescents' levels of fatigue and quality of life (r = -0.58). The mean levels of fatigue of the survivors group was significantly lower than that of those still receiving treatment in hospital, but significantly higher than that of their healthy counterparts. Confirmatory factor analysis indicated that there were 4 factors underlying the Chinese version of the Cancer Module. CONCLUSIONS: The findings of the study add further evidence that the Chinese version of the Fatigue Scale for Adolescents (12-item) can be used as a reliable and valid tool in assessing cancer-related fatigue among Hong Kong Chinese adolescents who have survived cancer.

Impact of brain tumor and its treatment on the physical and psychological well-being, and quality of life amongst pediatric brain tumor survivors.

PURPOSE: Compelling evidence has shown that pediatric brain tumor survivors are more susceptible to physical, neurocognitive, and psychological sequelae. This study assessed the impact of cancer and its treatment on the physical and psychological well-being, and quality of life of Hong Kong Chinese pediatric brain tumor survivors. METHODS: A total of 157 pediatric cancer survivors aged 8-16 were recruited. Of whom, 77 were pediatric brain tumor survivors and 80 were survivors of other cancers. Participants' depressive symptoms, level of self-esteem and quality of life were assessed. Additionally, 16 pediatric brain tumor survivors were randomly selected for a semi-structured interview. RESULTS: More than 70% pediatric brain tumor survivors presented significant number of depressive symptoms. Moreover, findings indicated that greater symptoms of depression in survivors were associated with lower level of self-esteem and quality of life. Qualitative interviews revealed that brain tumor and its treatment posed negative impact on the multiple domains of their daily life. CONCLUSION: The findings of this study has addressed the literature gap by showing pediatric brain tumors have poorer psychological well-being, in terms of greater number of depressive symptoms, lower levels of self-esteem, and more severely compromised quality of life than survivors of other pediatric cancers. It is vital for healthcare professionals to develop and evaluate appropriate interventions with the aims to enhance the psychological well-being and quality of life among pediatric brain tumor survivors.

The Impact of Hematologic Cancer and Its Treatment on Physical Activity Level and Quality of Life Among Children in Mainland China: A Descriptive Study.

BACKGROUND: The effects of hematologic cancer and its treatment on Chinese children's physical activity level and quality of life (QoL) remain unclear despite numerous studies conducted in Western countries and Hong Kong. OBJECTIVE: The aim of this study was to examine the effects of hematologic cancer and its treatment on the physical activity level and QoL among Chinese children. METHODS: A cross-sectional study was conducted. One hundred twenty-five children who were admitted for treatment of hematologic cancer and 243 healthy counterparts of similar age participated in this study. All participants were asked to complete the Chinese University of Hong Kong: Physical Activity Rating for Children and Youth and Pediatric Quality of Life Inventory. The children with hematologic cancer also completed a therapy-related symptom checklist. RESULTS: There were statistically significant differences in the mean physical activity and QoL between children with hematologic cancer and their healthy counterparts. Multiple regression analyses showed that physical activity levels and the adverse effects of hematologic cancer treatment had statistically significant effects on the children's QoL. CONCLUSIONS: Physical activity level and QoL in children with hematologic cancer were both lower than those in their healthy counterparts. IMPLICATIONS FOR PRACTICE: This study provides further evidence that hematologic cancer and the adverse effects of its treatment have negative effects on Chinese children's QoL. Although a lack of physical activity is deeply embedded in Chinese culture, nurses should take a proactive role in effecting change by educating parents about the benefits to their children's physiologic and psychological well-being of physical activity during and after treatment.

Relationships among fatigue, physical activity, depressive symptoms, and quality of life in Chinese children and adolescents surviving cancer.

PURPOSE: Fatigue is the most common concern reported by childhood cancer survivors. Assessing its occurrence and severity is a prerequisite for planning and evaluating appropriate interventions. Nevertheless, there is a lack of large-scale surveys which examine the occurrence and severity of fatigue and its associated factors. The study aimed to shed light on this under researched area. METHODS: A cross-sectional study was used. A total of 400 childhood cancer survivors (7- to 18-year olds) were invited to participate in the study. The cancer-related fatigue, depressive symptoms, physical activity level, and quality of life of participants were assessed. RESULTS: An average of 46.4% of children and 48.4% of adolescents were found to display symptoms of cancer-related fatigue between "half the time" and "all the time" over the previous seven days. Besides, greater occurrence and severity of fatigue in childhood cancer survivors were associated with more self-reported depressive symptoms, lower level of physical activity and quality of life. In addition, the study revealed that physical activity level is a significant factor associated with cancer-related fatigue. CONCLUSION: The findings provide further support that cancer and its treatment have adverse effects on survivors' fatigue, which can manifest months or even years after the completion of treatment. Importantly, this study reveals that physical activity is a significant factor associated with fatigue in children and adolescents. It is crucial for healthcare professionals to identify strategies that can help children and adolescents surviving cancer increase their adoption and maintenance of regular activity throughout their life.

The Psychometric Properties of the Chinese Version of the Fatigue Scale for Children.

BACKGROUND: The availability of a valid and reliable instrument that accurately assesses the level of fatigue among childhood cancer survivors is a prerequisite for developing and evaluating interventions designed to reduce fatigue. There is a lack of such an instrument for use in the Hong Kong Chinese context. OBJECTIVE: The aim of the study was to examine the psychometric properties of the Chinese version of the Fatigue Scale for Children. In particular, confirmatory factor analysis was conducted to examine its factorial structure. METHODS: A convenience sample of 200 Hong Kong Chinese children surviving cancer was recruited in an outpatient clinic. The psychometric properties of the Chinese version of the Fatigue Scale for Children were assessed. RESULTS: The content validity index was 0.83. There was a strong positive correlation between children's level of fatigue and depressive symptoms (r = 0.53) and a strong negative correlation between children's levels of fatigue and quality of life (r = -0.54). The mean levels of fatigue of the survivor group were significantly lower than those of those hospitalized with cancer, but significantly higher than those of their healthy counterparts. Confirmatory factor analysis indicated that there were 3 factors underlying the Chinese version of the Fatigue Scale for Children. CONCLUSION: The study adds further evidence that the Chinese version of the Fatigue Scale for Children can be used as a reliable and valid tool in assessing cancer-related fatigue among Chinese children who have survived cancer. IMPLICATIONS FOR PRACTICE: The translated scale can be used to develop and evaluate appropriate fatigue reduction interventions.
