The use of traditional, complementary and integrative medicine in Chinese adolescent and young adult patients with cancer: A multicenter cross-sectional study.

PURPOSE: Adolescent and young adult (AYA) patients with cancer often experience unique physical and psychosocial complications. They may turn to traditional, complementary and integrative medicines (TCIM) to address these concerns. To examine the pattern of TCIM use among AYA patients with cancer and explored their preferences regarding TCIM education. METHODS: Between August 2021 and December 2022, 246 patients diagnosed with cancer between 15 and 39 years old were recruited from hospitals in Hong Kong. They completed a structured questionnaire on TCIM use, symptom burden, psychological status and preference on education content. Multivariable logistic regression was used to identify predictors of TCIM use, adjusting for age and sex. RESULTS: Overall, 60.2% reported TCIM use, most commonly vitamins (24.0%) and Chinese herbal medicine (22.0%). The most common reasons for using TCIM were to improve general health (70.9%) and manage chronic symptoms (33.1%). Among patients on active treatment, TCIM users tend to report higher anxiety symptoms (aOR = 1.13, 95% CI = 1.02-1.27). TCIM users who were post-treatment were more likely to have chronic comorbidities (aOR = 3.54, 95% CI = 1.29-11.5). AYA patients indicated that they would like TCIM information to address specific needs, particularly fatigue (53.7%) and psychological problems (54.1%). CONCLUSIONS: The use of TCIM is common among AYA patients with cancer, especially among patients with high symptom burdens. A tailored education programme should be provided based on patients' preferences and needs. Healthcare professionals including oncologists and oncology nurses should communicate with AYA patients about TCIM use and address their needs by making evidence-based referrals/recommendations based on treatment status and symptom burden.

Clinical, neuroimaging, and behavioural risk factors for neurocognitive impairment in Chinese patients with haemophilia: A multicentre study.

BACKGROUND: Few studies have evaluated the impact of subclinical microstructural changes and psychosocial factors on cognitive function in patients with haemophilia. OBJECTIVES: To determine the prevalence and characteristics of cognitive impairment in patients with haemophilia, and identify associated risk factors. METHODS: We recruited haemophilia A or B patients who were aged ≥10 years old from three public hospitals in Hong Kong. A neurocognitive battery was administered to evaluate their attention, memory, processing speed and cognitive flexibility performances. They also underwent magnetic resonance imaging to identify cerebral microbleeds. Validated self-reported questionnaires were administered to assess their mental health status and adherence to prophylactic treatment. General linear modelling was used to investigate the association of neurocognitive outcomes with risks factors, adjusting for age and education attainment. RESULTS: Forty-two patients were recruited (median age 32.0 years; 78.6% haemophilia A; 80.9% moderate-to-severe disease). Six patients (14.3%) had developed cerebral microbleeds. A subgroup of patients demonstrated impairments in cognitive flexibility (30.9%) and motor processing speed (26.2%). Hemarthrosis in the previous year was associated with worse attention (Estimate = 7.62, 95% CI: 1.92-15.33; p = .049) and cognitive flexibility (Estimate = 8.64, 95% CI: 2.52-13.29; p = .043). Depressive (Estimate = 0.22, 95% CI: 0.10-0.55; p = .023) and anxiety (Estimate = 0.26, 95% CI: 0.19-0.41; p = .0069) symptoms were associated with inattentiveness. Among patients receiving prophylactic treatment (71.4%), medication adherence was positively correlated with cognitive flexibility (p = .037). CONCLUSION: A substantial proportion of patients with haemophilia demonstrated cognitive impairment, particularly higher-order thinking skills. Screening for cognitive deficits should be incorporated into routine care. Future studies should evaluate the association of neurocognitive outcomes with occupational/vocational outcomes.

Associations between Lifestyle Factors and Neurocognitive Impairment among Chinese Adolescent and Young Adult (AYA) Survivors of Sarcoma.

BACKGROUND: The effect of lifestyle on neurocognitive impairment among cancer survivors remain an understudied area. This study explored the association between lifestyle factors and neurocognitive outcomes (specifically, attention, memory, processing speed and cognitive flexibility) in AYA survivors (aged 15-39 years) of sarcoma. METHODS: This study recruited 116 AYA survivors (age 28.2 (SD = 8.2) years), who were diagnosed with osteosarcoma (49%) or soft-tissue sarcoma (51%) at age 13.3 (SD = 7.2) years. The neurocognitive battery included measures of attention, memory, motor-processing speed, and cognitive flexibility. Survivors reported health-damaging practices, which included: physical inactivity, smoking, alcohol intake, inadequate sleep (<7 h of actual sleep/day), sleep-related fatigue (Multidimensional Fatigue Scale) and long working hours (>9 h/day). General linear modeling was conducted to examine the association between lifestyle factors and neurocognitive outcomes, adjusting for age at diagnosis, sex, education attainment and clinical/treatment variables. RESULTS: At 14.9 (SD = 7.6) years post-diagnosis, survivors demonstrated impairment in attentiveness (4.3-13.0%), processing speed (34.5%) and cognitive flexibility (18.1%). Nearly half (45.7%) had developed a chronic health condition (CHC). Low physical activity (estimate = -0.97, p = 0.003) and sleep-related fatigue (estimate = -0.08, p = 0.005) were associated with inattention. Survivors who worked >9 h/day (n = 15) demonstrated worse attention (estimate = 5.42, p = 0.023) and cognitive flexibility (estimate = 5.22, p = 0.005) than survivors who worked ≤9 h/day (n = 66). Interaction analysis (CHCs*physical activity) showed that survivors who developed CHCs and reported low physical activity had worse attention (p = 0.032) and cognitive-flexibility (p = 0.019) scores than other subgroups. CONCLUSION: Treatment-related CHCs, coupled with continued physical inactivity, may exacerbate inattention and executive dysfunction among survivors. Long working hours and sleep-related fatigue are associated with worse functioning; this finding should be validated with prospective assessment of work-related stressors and objective sleep measures.

Provision of a personalized survivorship care plan and its impact on cancer-related health literacy among childhood cancer survivors in Hong Kong.

PURPOSE: To evaluate the short-term effectiveness of a personalized survivorship care plan (SCP) in improving cancer-related literacy among childhood cancer survivors, and to identify characteristics of survivors who demonstrated minimal gain from the intervention. METHODS: We recruited survivors diagnosed with cancer at ≤18 years old and were >2 years post treatment. The intervention included a personalized SCP and 30-minute health risk counseling. The participants' knowledge of their cancer diagnosis and potential treatment-related late effects (LEs) was assessed at baseline, immediately post intervention, and 1-3 months post intervention. Generalized estimating equation was used to test for changes in the awareness scores, with interacting terms (time*factor) added to identify differences in the score trajectory across clinically relevant subgroups. RESULTS: In total, 248 survivors completed the intervention (mean age: 19.4 [SD = 6.7] years; 54.1% male; 66.1% hematological malignancies), of whom 162 completed all assessments. There was significant increase in survivors' awareness of their cancer diagnoses (mean adjusted score: baseline 66.9, post intervention 86.3; p < .001) and potential LEs (baseline 30.9, post intervention 66.3; p < .001). The proportion of survivors who demonstrated awareness of their potential LEs increased from 9.7% to 54.3%. The interaction analysis showed that there was significantly less improvement in awareness among survivors of non-central nervous system (non-CNS) solid tumors (p = .032), lower socioeconomic status (p = .014), and parents of pediatric survivors (vs. adult survivors; p = .013). CONCLUSIONS: The provision of a personalized SCP showed preliminary effectiveness in improving survivors' understanding of their treatment-related LEs. Health counseling with SCP should be reinforced in vulnerable subgroups. Future work includes evaluating its long-term impact on lifestyle and health outcomes.

Treatment Adherence and Health-Related Quality of Life in Patients with Hemophilia in Hong Kong.

Background: This study aims to identify factors affecting health-related quality of life (HRQoL) in Chinese patients with hemophilia in Hong Kong, and to examine the association between treatment adherence and HRQoL outcomes. Methods: Patients with hemophilia A or B from a non-governmental organization reported their HRQoL and treatment adherence to prophylactic therapy using validated tools. Univariate tests and multivariable regression analysis were used to compare differences in outcomes across clinically relevant subgroups. Results: Fifty-six patients were recruited (mean age 30.4 [17.4] years; majority hemophilia A: 75%; moderate-to-severe severity: 88%). Patients who received prophylactic treatment reported fewer work/school problems (25.8 [18.9] versus 51.5 [26.3]; p = 0.001) than those who received on-demand therapy. The multivariable model showed that older age (B = 0.42, 95% CI = 0.093−0.75) and living in public housing (B = 10.24, 95% CI = 0.70−19.77) were associated with worse HRQoL. Older age was associated with treatment non-adherence (r = 0.66, p < 0.0001). Patients with poor adherence tended to report worse functioning in sports/leisure (r = 0.31, p = 0.033). Conclusions: Our results suggest that patients who were older, had lower education attainment and received on-demand treatment had poorer perception of their health. Improving adherence may lead to better HRQoL. Future work includes evaluating the occupational needs prospectively in this population.

Real-world data on herb-drug interactions in oncology: A scoping review of pharmacoepidemiological studies.

BACKGROUND: The concurrent use of conventional drugs and herbal medicines is becoming popular among patients with cancer. However, the potential risk of herb-drug interactions (HDI) remains under-addressed in the literature. Previous reviews have mainly focused on the prevalence of interactions, with less attention paid to the methods used by pharmacoepidemiological studies on evaluating HDI. This scoping review aims to summarize the existing pharmacoepidemiological studies that evaluate HDI using real-world data and to identify gaps to be addressed in future research. METHODS: A comprehensive search was performed in nine English- and Chinese-language databases from their inception to May 2021. Gray literature and manual searches were conducted to identify additional studies. The recommended components of the pharmacoepidemiological studies and key findings related to HDI were summarized. The proportion (%) of patients with cancer at risk of HDI was estimated by combining data from eligible studies. RESULTS: Twenty-eight studies were included in the review. More than half of these studies were cross-sectional studies (n = 18, 64.3%), followed by retrospective cohort studies (n = 5, 17.9%) and prospective cohort studies (n = 2, 7.1%). The three cancer drugs most commonly studied for their interaction potential with herbs were tamoxifen (n = 11, 39.3%), cyclophosphamide (n = 6, 21.4%), and paclitaxel (n = 6, 21.4%). Most cross-sectional studies identified potential HDI using tertiary databases and primary literature searches. Conversely, prospective and retrospective studies mainly investigated actual clinical outcomes, such as adverse events and secondary cancer occurrences. Most interaction outcomes identified using real-world data did not lead to negative clinical consequences. Collectively, 45.4% of herbal medicine users of the included studies were found to be at risk of HDI. We infer from this review that the common limitations of these studies were limited sample size, lack of data on herbal medicine use and details of HDI, and lack of evidence of HDI. Based on the study limitations, several recommendations to enrich the data sources and optimize the study designs were proposed. CONCLUSIONS: There is a high demand for pharmacoepidemiological research on HDI, considering the increasing popularity of herbal medicine among patients with cancer. It is anticipated that emerging real-world data in this field can guide the development of safe and effective approaches to integrative oncology.

Awareness of diagnosis, treatment and risk of late effects in Chinese survivors of childhood cancer in Hong Kong.

BACKGROUND: For survivors of childhood cancer, awareness of personal health risks is a critical component of long-term health management. OBJECTIVE: To evaluate the awareness of the diagnosis, treatment and risk of late effects among survivors of childhood cancer in Hong Kong. METHODS: Between June 2019 and March 2020, this cross-sectional study recruited 155 adult survivors (mean age = 26.9, standard deviation [SD] = 6.4 years) and 45 parents of paediatric survivors (mean age = 11.1, SD = 3.6 years) from a long-term follow-up clinic. At >10 years post-treatment (mean = 13.4, SD = 7.6 years), they completed a structured questionnaire to report their cancer-specific knowledge. Multiple linear regression analysis was conducted to identify clinical, socioeconomic and behavioural factors associated with poor awareness. RESULTS: The majority of participants accurately recalled their diagnoses (73.5%) and major treatment modalities (chemotherapy 92.4%, radiation 82.9% and surgery 88.2%). However, less than half (45%) of the participants recognized more than 25% of the total late effects for which they were at risk. The highest levels of awareness were reported for endocrine problems (49%), neurocognitive impairment (44%) and secondary cancers (43%), and the lowest for peripheral neuropathy (21%) and vision problems (23%). Compared with survivors of haematological malignancies, those of central nervous system (CNS) tumours (standardized estimate [B] = -9.33, 95% confidence interval [95% CI]: -13.41 to -5.26) and non-CNS solid tumours (B = -8.47, 95% CI: -12.39 to -4.94) had less knowledge about their diagnosis. Retaining medical records (P < .0001) and better medical information-seeking habits (P = .048) were associated with better awareness. CONCLUSIONS: Survivors of childhood cancer in Hong Kong have deficient awareness of their personal health risks. They may benefit from the provision of a survivorship care plan and personalized education regarding treatment-related late effects. PATIENT CONTRIBUTION: Patients contributed in designing the study tools. Results were presented at a non-governmental organization.
