The association of weight loss from anti-obesity medications or bariatric surgery and apnea-hypopnea index in obstructive sleep apnea.

INTRODUCTION: Weight loss is recommended for individuals with obstructive sleep apnea (OSA) and overweight or obesity, but there is limited evidence to guide the selection of weight management strategies for patients who do not lose sufficient weight with diet and lifestyle changes. We evaluated the relationship between weight loss caused by pharmacologic or surgical interventions and subsequent improvement in OSA by the apnea-hypopnea index (AHI). METHODS: PubMed, Cochrane CENTRAL, and EMBASE were searched for randomized trials comparing pharmacologic or surgical obesity interventions to usual care, placebo, or no treatment in adults with OSA. The association between percentage weight loss and AHI change between randomization and last follow-up was evaluated using meta-regression. PROSPERO: CRD42022378853. RESULTS: Ten eligible trials (n = 854 patients) were included. Four (n = 211) assessed bariatric surgery, and 6 (n = 643) assessed pharmacologic interventions over a median follow-up of 13 months (interquartile range 6-26 months). The linear best estimate of the change in AHI is 0.45 events per hour (95% Confidence Interval 0.18 to 0.73 events per hour) for every 1% body weight lost. CONCLUSIONS: Weight loss caused by medication or surgery caused a proportionate improvement of the AHI. Providers could consider extrapolating from this relationship when advising patients of the expected effects of other pharmacologic or surgical interventions without direct evidence in OSA.

Factors Affecting Patient and Caregiver Preferences for Treatment of Myeloma and Indolent Lymphoma.

PURPOSE: Treatment options for myeloma and indolent lymphoma are increasing exponentially, with distinct efficacy, side effects, and cost. We aim to determine the factors influencing patient and caregiver treatment preferences. METHODS: Patients and caregivers of patients with myeloma and indolent lymphoma were recruited from two cancer centers in Singapore. Preferences were elicited using a discrete choice experiment. Attributes and levels were selected based on a previous qualitative study. The relative preference for levels within each attribute (part worth utility values) and the extent to which an attribute would influence decision making (relative importance) were calculated. Patient and caregiver participation in the treatment plan selection process were assessed using the Control Preference Scale. RESULTS: One hundred ninety-nine patients and 169 caregivers were recruited. Patients placed the highest importance on out-of-pocket costs (relative importance = 35%), followed by efficacy (25%), persistent side effects (19%), administration route (8%), treatment duration (7%), and short-term side effects (5%). Caregivers ranked efficacy (27%) as the most important attribute, over out-of-pocket costs (24%). Most patients preferred a collaborative role in the shared decision-making process, while similar proportions of caregivers favored active and collaborative roles. CONCLUSION: Our study demonstrates that both patients and caregivers consider cost seriously when making treatment decisions. Furthermore, as patient and caregiver preferences may differ, there are implications for treatment selection and counseling, especially in cultures where caregivers have more prominent roles in treatment planning.

Brain-derived neurotrophic factor as a biomarker in cancer-related cognitive impairment among adolescent and young adult cancer patients.

Brain-derived neurotrophic factor (BDNF) improves cognitive function by stimulating neurogenesis and neuroplasticity. We hypothesize that higher plasma BDNF levels are protective against cognitive toxicity among adolescent and young adult cancer patients (15-39 years old). In a prospective, longitudinal study, we recruited 74 newly diagnosed cancer and 118 age-matched non-cancer controls who completed the Cambridge Neuropsychological Test Automated Battery (CANTAB), Functional Assessment of Cancer Therapy-Cognitive Function questionnaire (FACT-Cog) and blood draws. Plasma BDNF was quantified using an enzyme-linked immunosorbent assay. Genomic DNA from buffy coat was genotyped for BDNF Val66Met. Most cancer participants were diagnosed with breast (24%) and head/neck (22%) cancers. After adjusting for sociodemographic variables (age, gender, race, marital status, education years), cancer participants had lower BDNF levels (ng/mL) at baseline (median: 10.7 vs 21.6, p < 0.001) and 6-months post-baseline (median: 8.2 vs 15.3, p = 0.001) compared to non-cancer controls. Through linear mixed modelling adjusted for sociodemographic variables, baseline cognition, fatigue, psychological distress, and time, we observed that among cancer participants, lower baseline BDNF levels were associated with worse attention (p = 0.029), memory (p = 0.018) and self-perceived cognitive abilities (p = 0.020) during cancer treatment. Met/Met was associated with enhanced executive function compared to Val/Val (p = 0.012). Plasma BDNF may serve as a predictive biomarker of cancer-related cognitive impairment.

Cost-effectiveness analysis of the SMART quit clinic program in smokers with cardiovascular disease in Thailand.

INTRODUCTION: The SMART Quit Clinic Program (FAHSAI Clinic) has been implemented in Thailand since 2010; however, it remains unclear whether the benefits gained from this program justify its costs. We assessed its cost-effectiveness compared to usual care in a population of Thai smokers with cardiovascular disease (CVD) from a societal perspective. METHODS: We conducted a cost-utility analysis using a Markov model to simulate lifetime costs and quality-adjusted life years (QALYs) of Thai smokers aged ≥35 years receiving smoking cessation services offered from FAHSAI Clinic or usual care over a horizon of 50 years. The model used a 6-month continuous abstinence rate from a multicenter prospective study of 24 FAHSAI Clinics. A series of sensitivity analyses including probabilistic sensitivity analysis were conducted to assess robustness of study findings. Cost data are presented in US$ for 2020. RESULTS: The FAHSAI Clinic was dominant as it was less costly ($9537.92 vs $10964.19) and more effective (6.06 vs 5.96 QALYs) compared with usual care over the 50-year time horizon. Changes in risks of stroke and coronary heart disease among males had the largest impact on the cost-effectiveness findings. The probability that FAHSAI Clinic was cost-effective was 99.8% at a willingness-to-pay threshold of $5120. CONCLUSIONS: The FAHSAI Clinic smoking cessation program was clinically superior and cost-saving compared to usual care for Thai patients with CVD in all scenarios. A budget impact analysis is needed to estimate the financial impact of adopting this program within the Thai healthcare system.

Cancer incidence in immunocompromised patients: a single-center cohort study.

BACKGROUND: Diminished immune defense plays an important role in cancer development. Cancer risk in immunocompromised patients may differ. Identifying individuals with elevated cancer risk can inform strategies for routine cancer screening. This study aimed to understand and compare cancer incidence and risk in three patient groups: recipients of solid organ transplant (SOT) or hematopoietic stem cell transplant (HSCT); diagnosis of primary or secondary immunodeficiency disorder (PID/SID); and recipients of tumor necrosis factor inhibitor (TNF-i) therapy. METHODS: This retrospective cohort study used the University of Utah Health System database and Huntsman Cancer Institute tumor registry. Patients aged ≥18 years with SOT/HSCT, PID/SID or ≥ 3 months of TNF-i therapy were included. The date of transplant, diagnosis of PID/SID, or 1st TNF-i medication order date was defined as the index date. We calculated cumulative cancer incidence by Kaplan-Meier method. A Cox-proportional hazard regression model with a stepwise variable selection process was used to identify independent risk factors associated with the time to onset of a new primary cancer. RESULTS: In total, 13,887 patients were included which comprised of 2982 (21%) SOT/HSCT, 7542 (54%) PID/SID and 3363 (24%) patients receiving TNF-i. The mean (SD) age ranged from 46.8 (15) years - 50.4 (18.2) years. The proportion of white patients ranged from 72.3-84.8%. The estimated cumulative cancer incidence was 11.5% in the SOT/HSCT cohort, 14.3% in the PID/SID cohort, and 8.8% in the TNF-i cohort. The multivariable model adjusted for age, benign in-situ disease, Charlson Comorbidity Index, hypertension/cardiovascular disease/end stage renal disease, gender, race/ethnicity, and renal cyst as significant risk factors. The adjusted hazard ratios for cancer development in SOT/HSCT and PID/SID cohorts compared to the TNF-i cohort over the full follow-up period were 1.57 (95% CI: 1.16-2.13) and 2.14 (95% CI: 1.65-2.77), respectively. CONCLUSION: A significantly increased risk of cancer was observed in PID/SID patients and SOT/HSCT patients compared to TNF-i patients. Age ≥ 50 years, male gender, and clinical comorbidities were additional factors impacting cancer risk. PID/SID and SOT/HSCT patients may benefit from more intensive cancer screening.

Work Outcomes and Medical Costs Among Singaporean Adolescent and Young Adult Cancer Survivors.

Purpose: To quantify and evaluate trends of work outcomes and medical costs among Singaporean adolescent and young adult (AYA) cancer survivors. Methods: This cross-sectional study was conducted at the National Cancer Centre Singapore between July 2016 and October 2018. Cancer patients who were diagnosed between the age of 15 and 39 years and had completed treatment were eligible. Siblings of cancer patients were recruited as controls. Work outcomes were collected using an investigator-designed questionnaire, while cost data were extracted from the hospital database. Descriptive statistics were used to quantify work and cost outcomes. Mixed-effects logistic regression was used to compare employment rates between survivors and controls. Generalized linear models were used to characterize trends between medical costs and symptom burden. Results: A total of 29 cancer survivors and 23 sibling controls were analyzed. Approximately 80% of survivors and controls were employed at the time of survey; however, more than half of the employed survivors reported impaired work outcomes due to effects from cancer and cancer treatment, including work reallocation, absenteeism, and decreased work ability. Median productivity loss due to absenteeism in the past 3 months was estimated to be U.S. dollar (USD) 110. Total medical cost incurred within the first year after treatment completion remained high at a median of USD6592, with out-of-pocket expenditure between 17.2% and 100.0%. Conclusion: Despite their young age and having completed cancer treatment, Singaporean AYA cancer survivors may continue to experience poor work outcomes even after resuming work. High medical costs may also persist.

Cognitive impairment in adolescent and young adult cancer patients: Pre-treatment findings of a longitudinal study.

BACKGROUND: There is little information about cancer-related cognitive impairment (CRCI) in adolescent and young adults (AYA, 15-39 years old) due to its rare incidence. Here, we present the pre-treatment (before chemotherapy or radiotherapy) evaluation of cognitive function and ability of AYA with cancer (AYAC) in a multicentered cohort study. METHODS: Newly diagnosed AYAC and age-matched healthy controls (HC) were recruited between 2018 and 2021. The primary outcome was the comparison of pre-treatment cognitive impairment defined as 2 standard deviations (SDs) below the HC on ≥1 cognitive test, or >1.5 SDs below on ≥2 tests using CANTAB® between AYAC and HC. Secondary outcomes included self-perceived cognitive ability assessed by FACT-Cog v3 and biomarkers (inflammatory cytokines and brain-derived neurotrophic factor [BDNF]). RESULTS: We recruited 74 AYAC (median age = 34) and 118 HC (median age = 32). On objective cognitive testing, we observed three times more AYAC patients performed poorly on at least 2 cognitive tests compared to HC (40.5% vs. 13.6%, p < 0.001). AYAC self-perceived less degree of cognitive impairment than HC (p < 0.001). However, AYAC perceived a greater impact of cognitive changes on their quality of life compared to HC (p = 0.039). Elevated baseline inflammatory markers (IL-2, IL-4, IL-6, IL-8, IL-10 and IFN-γ) were observed among AYAC compared to HC, and baseline BDNF was lower in AYAC compared to HC. Interaction effects between cancer diagnosis and biomarkers were observed in predicting cognitive function. CONCLUSION: With the pre-existence of CRCI and risk factors of neuroinflammation even prior to systemic therapy, AYAC should receive early rehabilitation to prevent further deterioration of cognitive function after initiation of systemic therapies.

Longitudinal evaluation of dehydroepiandrosterone (DHEA), its sulfated form and estradiol with cancer-related cognitive impairment in early-stage breast cancer patients receiving chemotherapy.

The purpose of this study is to elucidate how patient-reported cognitive symptoms manifest from variations in hormone levels or precursors such as dehydroepiandrosterone (DHEA) and its sulfated form [collectively termed as DHEA(S)] and to investigate their association in breast cancer survivors. Levels of estradiol and DHEA(S) were compared between early-stage breast cancer patients with and without cancer-related cognitive impairment (CRCI) during adjuvant chemotherapy. Data were analyzed from 242 patients (mean age ± SD = 50.8 ± 9.2 years) who had completed FACT-Cog v.3.0, blood draws and questionnaires. Regression model was used to fit the magnitude of change in each respective biomarker levels against overall cognitive impairment status while adjusting for clinically important covariates. There was reduction in mean plasma levels of estradiol and DHEAS during and towards the end of chemotherapy (p-values < 0.001). Compared to non-impaired patients, smaller magnitude of decline was observed in DHEA(S) levels in patients reporting CRCI, with significant association between decline in DHEAS levels and acute onset of CRCI at 6 weeks from baseline (adjusted ß of 0.40, p-value of 0.02). In contrast, patients reporting CRCI showed greater magnitude of decline in estradiol compared to non-impaired patients, although this was not found to be statistically significant. There was an association between magnitude of change in biomarker levels with self-reported CRCI which suggests that the hormonal pathway related to DHEAS may be implicated in acute CRCI for breast cancer survivors. Our findings help to improve biological understanding of the pathway from which DHEAS may correlate with cognitive dysfunction and its impact on cancer survivors.

Adherence to Cancer Survivorship Care Guidelines and Health Care Utilization Patterns Among Nonmetastatic Breast Cancer Survivors in Singapore.

PURPOSE: Currently, limited information is available on care provided to breast cancer survivors in Singapore. This study aims to assess the quality of post-treatment cancer survivorship care among breast cancer survivors on the basis of compliance with international guidelines up to 5 years post-primary treatment. METHODS: This study analyzed a cohort of 189 nonmetastatic breast cancer survivors recruited from the National Cancer Centre Singapore, Changi General Hospital, and KK Women's and Children's Hospital between November 2011 and September 2015. Data were retrieved from electronic medical records in 6-month intervals. Adherence to guidelines was assessed in four areas: (1) recurrent cancer surveillance, (2) monitoring and detecting late effects, (3) health care resource utilization, and (4) preventive care. Descriptive statistics, Kaplan-Meier, and regression analyses were conducted. RESULTS: Annual surveillance mammogram adherence rates were ≥ 83% consistently. The most common new diagnosis was osteoporosis at an incidence rate of 102 (95% CI, 77.6 to 135) cases per 1,000 person-years. Overall, ≤ 10.1% of survivors had an emergency department or hospitalization visit. Oncologist services were overutilized, with a median of 6 (interquartile range: 4-10) visits in the first 6 months before reducing to a median of 2 (interquartile range: 1-3) visits biannually 3 years post-treatment. Bone mineral density test utilization rate adhered to guidelines for 92.2% of aromatase inhibitor recipients but only for 36.4% of premenopausal tamoxifen recipients. CONCLUSION: Overall, adherence rates to surveillance and osteoporosis preventive care were high. Extensive utilization of oncologist services up to 5 years post-primary treatment could be reversed with strategies to engage and coordinate survivorship care with primary care providers, leveraging their strengths to improve adherence to health promotion and chronic disease management.

Distinct financial distress profiles in patients with breast cancer prior to and for 12 months following surgery.

BACKGROUND: Study purposes were to identify subgroups of patients with breast cancer with distinct self-reported financial distress (FD) profiles and determine which demographic, clinical and symptom characteristics, as well as quality of life (QOL) outcomes were associated with subgroup membership. METHODS: Patients (n=391) who were assessed for changes in FD a total of 10 times from prior to through 12 months after breast cancer surgery. Latent profile analysis was used to identify subgroups of patients with distinct FD profiles. RESULTS: Three distinct FD profiles (ie, None (14.6%), Low (52.7%), High (32.7%)) were identified. Compared with None and/or Low subgroups, patients in the High subgroup were more likely to report a lower annual household income and performance status; had a higher body mass index, axillary lymph node dissection and more advanced stage disease; had a longer time from cancer diagnosis to surgery; and had received neoadjuvant or adjuvant chemotherapy. In addition, patients in the High subgroup reported higher fatigue, sleep disturbance, state/trait anxiety, depressive symptom scores, and lower attentional function and QOL scores. CONCLUSION: This study provides new insights on risk factors for and evidence of a higher symptom burden associated with FD. Findings from this study provide clinicians with information on how to identify high-risk patients and to recommend appropriate interventions for both symptom management and FD. Additional research on the mechanisms that underlie the relationships among FD and common physical and psychological symptoms may inform future interventions.

Investigating how cancer-related symptoms influence work outcomes among cancer survivors: a systematic review.

PURPOSE: The purpose of this study is to investigate how different cancer-related symptoms influence work outcomes among cancer survivors. METHODS: A literature search was performed in PubMed, EMBASE, CINAHL, PsycINFO, and Scopus to identify studies published between 1st January 1999 and 30th October 2020 that investigated the impact of specific cancer-related symptoms on work outcomes among cancer survivors who have completed primary antineoplastic treatment. Study findings were extracted and grouped by symptoms and work outcomes, allowing comparison of associations between these outcomes. RESULTS: Seventy-three articles representing 68 studies were eligible for inclusion. From these studies, 27 cancer-related symptoms, 9 work outcomes, and 68 unique associations between specific symptoms and work outcomes were identified. Work status (return to work and employment rates) was most commonly studied, and symptom burden was mainly measured from the patient's perspective. Higher symptom burden was generally associated with trends of poorer work outcomes. Significant associations were reported in most studies evaluating body image issues and work status, oral dysfunction and work status, fatigue and work ability, and depression and work ability. CONCLUSION: Several cancer-related symptoms were consistently associated with inferior work outcomes among cancer survivors. Body image issues and oral dysfunction were shown to be associated with poorer employment rates, while fatigue and depression were linked to lower levels of work performance. IMPLICATIONS FOR CANCER SURVIVORS: Failure to return to work and decreased productivity post-cancer treatment can have negative consequences for cancer survivors and society at large. Findings from this review will guide the development of work rehabilitation programs for cancer survivors. PROTOCOL REGISTRATION: PROSPERO identifier CRD42020187754.

Characteristics associated with inter-individual variability in financial distress in patients with breast cancer prior to and for 12 months following surgery.

PURPOSE: To evaluate for inter-individual differences in financial distress and identify demographic, clinical, and symptom characteristics associated with higher levels of financial distress. METHODS: Patients (n = 387) were enrolled prior to breast cancer surgery and followed for 12 months. Financial distress was measured using a 0 (no problem) to 10 (severe problem) numeric rating scale. Hierarchical linear modeling was used to evaluate for inter-individual differences in trajectories of financial distress and characteristics associated with financial distress at enrollment and over 12 months. RESULTS: Patients' mean age was 55.0 (± 11.7) years and the majority underwent breast conservation surgery (80.6%). Mean financial distress score prior to surgery was 3.3 (± 3.4; range 0 to 10). Unconditional model for financial distress demonstrated no significant changes over time (-0.006/month). Younger age, lower income, receipt of an axillary lymph node dissection and adjuvant chemotherapy, and lower attentional function were associated with higher preoperative levels of financial distress. CONCLUSION: Risk factors identified in this study can be used to inform clinicians regarding the need to initiate financial discussions and social work referrals for some patients. Additional clinical or system level interventions should be considered for vulnerable groups with these risk factors.

Distinct employment interference profiles in patients with breast cancer prior to and for 12 months following surgery.

PURPOSE: To identify subgroups of female breast cancer patients with distinct self-reported employment interference (EI) profiles and determine which demographic, clinical, and symptom characteristics, and quality of life outcomes were associated with subgroup membership. METHODS: Women with breast cancer (n = 385) were assessed for changes in EI over ten times, from prior to, through 12 months after breast cancer surgery. Latent profile analysis (LPA) was used to identify subgroups of patients with distinct EI profiles. RESULTS: Three distinct EI profiles (i.e., None - 26.2% (n = 101), Low - 42.6% (n = 164), High - 31.2% (n = 120)) were identified. Compared to the None and Low groups, patients in the High group were more likely to be younger. Higher proportions in the High group were non-White, pre-menopausal prior to surgery, had more advanced stage disease, had received an axillary lymph node dissection, had received neoadjuvant chemotherapy, had received adjuvant chemotherapy, and had a re-excision or mastectomy on the affected breast within 6 months after surgery. In addition, these patients had lower quality of life scores. Compared to the None group, the High group had higher levels of trait and state anxiety, depressive symptoms, fatigue and sleep disturbance and lower levels of cognitive function. CONCLUSIONS: This study provides new knowledge regarding EI profiles among women in the year following breast cancer surgery. The non-modifiable risk factors (e.g., younger age, being non-White, having more advanced stage disease) can inform current screening procedures. The potentially modifiable risk factors can be used to develop interventions to improve employment outcomes of breast cancer patients.

International Society of Oncology Pharmacy Practitioners (ISOPP) position statement: Role of the oncology pharmacy team in cancer care.

The Oncology Pharmacy Team (OPT), consisting of specialty-trained pharmacists and/or pharmacy technicians, is an integral component of the multidisciplinary healthcare team (MHT) involved with all aspects of cancer patient care. The OPT fosters quality patient care, safety, and local regulatory compliance. The International Society of Oncology Pharmacy Practitioners (ISOPP) developed this position statement to provide guidance on five key areas: 1) oncology pharmacy practice as a pharmacy specialty; 2) contributions to patient care; 3) oncology pharmacy practice management; 4) education and training; and 5) contributions to oncology research and quality initiatives to involve the OPT. This position statement advocates that: 1) the OPT be fully incorporated into the MHT to optimize patient care; 2) educational and healthcare institutions develop programs to continually educate OPT members; and 3) regulatory authorities develop certification programs to recognize the unique contributions of the OPT in cancer patient care.

Relationship between cytokines and brain-derived neurotrophic factor (BDNF) in trajectories of cancer-related cognitive impairment.

Cytokines facilitate the peripheral immune and cerebral response, through their ability to modulate the expression of brain derived neurotrophic factor (BDNF). Cytokines and BDNF are implicated in cancer-related cognitive impairment (CRCI), but their relationship has not been clearly defined for this condition. The aim of this study was to evaluate the associations of cytokines and BDNF among early stage breast cancer (ESBC) patients with different CRCI trajectories. This was a multicenter longitudinal study involving 136 ESBC patients. CRCI was assessed using the FACT-Cog (V3) questionnaire. Plasma cytokines and BDNF levels were quantified at three time points throughout chemotherapy. The associations between cytokines and BDNF were analyzed using linear mixed models, with interaction terms for CRCI status. All cytokines analyzed showed inverse associations with BDNF levels. There was a significant interaction between IL-6 and the persistent impairment trajectory, which would impact on BDNF levels (p = 0.026). The inverse associations with BDNF were more pronounced for IFN-γ, IL-1ß, IL-4, IL-8, and GM-CSF in patients with persistent CRCI. The coefficient values for IL-2, IL-4, and TNF-α also indicate that there was a greater magnitude of decrease in BDNF level for every unit of cytokine increase in patients with acute and persistent CRCI, compared to patients without CRCI. The differential associations between cytokines and BDNF may be indicative of probable susceptibility to the elevation of cytokines. Further research is required to elucidate the specific associations of cytokines and BDNF, along with their contributions to acute and persistent CRCI.

Clinical and economic evaluation of a surveillance protocol to manage hepatitis B virus (HBV) reactivation among lymphoma patients with resolved HBV infection receiving rituximab.

STUDY OBJECTIVE: To evaluate a surveillance protocol in managing the risk of hepatitis B virus (HBV) reactivation among lymphoma patients with resolved HBV infection receiving rituximab. DESIGN: Prospective, single-arm study. SETTING: National Cancer Centre, Singapore. PATIENTS: Lymphoma patients with resolved HBV infection and scheduled to receive rituximab-based treatment. INTERVENTION: Close monitoring of HBV DNA levels, ie. every 4-6 weeks during rituximab treatment, every 6-8 weeks in the first year post-treatment, and every 3-4 months in the second year post-treatment. MEASUREMENTS: The efficacy of the surveillance protocol was examined by evaluating the rates of reactivation-related events. Feasibility was evaluated based on patient adherence. An economic analysis using a cost-minimization approach was conducted to compare the costs between the surveillance protocol and universal prophylaxis with entecavir 0.5 mg daily up to 1 year after cessation of rituximab. MAIN RESULTS: A total of 66 patients provided analyzable data with a follow-up period of 966.6 months. No hepatitis flare or reactivation-related events were detected. The median adherence rate to the surveillance protocol was 90.5%. Cost savings of US$946.40 per patient over the entire surveillance period were achieved if the surveillance protocol was adopted and was most affected by changes in prophylaxis duration and the cost of antiviral prophylaxis. CONCLUSIONS: The surveillance protocol is an effective, feasible and cost-saving strategy to manage HBV reactivation among lymphoma patients with resolved HBV infection receiving rituximab.

Educational needs of oncology pharmacists: A survey by the International Society of Oncology Pharmacy Practitioners.

BACKGROUND: The International Society of Oncology Pharmacy Practitioners (ISOPP) is committed to providing educational resources to members for their continuous learning and professional development. This survey was conducted to explore the educational needs of International Society of Oncology Pharmacy Practitioners members for the purpose of developing resources to support future learning relevant to the diverse global pharmacy practitioner membership of our society. METHODS: A cross-sectional survey of International Society of Oncology Pharmacy Practitioners membership was conducted between 10 December 2018 and 15 January 2019. The survey contained 17 questions and consisted of four sections: (1) respondents' demographics, (2) common challenges/barriers faced by members in accessing oncology pharmacy education, (3) areas within oncology pharmacy where members need education and (4) preferred methods of education delivery. Descriptive statistics were utilized to summarize survey results. RESULTS: The survey was completed by 62 out of 363 International Society of Oncology Pharmacy Practitioners members (17% response rate). Respondents were from 19 different countries, representing all the habitable continents. Most respondents were practicing in North America (21%), Oceania (21%) and Asia (16%). The majority of respondents worked in inpatient cancer units (60%), ambulatory tertiary cancer centres (31%) and academia (26%). Reported barriers to accessing education relevant to oncology pharmacy practice included lack of financial support (44%), time spent travelling to attend educational activities (39%), limited learning opportunities in their country of practice (34%) and limited growth of the oncology pharmacy discipline in their country of practice (32%). The content areas of greatest demand included pharmacotherapy of various cancers followed by oncology pharmacy research, International Society of Oncology Pharmacy Practitioners oncology pharmacy practice standards, supportive care and medication safety. Among educational activities offered by International Society of Oncology Pharmacy Practitioners, respondents valued annual International Society of Oncology Pharmacy Practitioners symposia and Journal of Oncology Pharmacy Practice the most. Most respondents (87%) indicated webinars as an effective educational tool. CONCLUSION: Among an international oncology pharmacist cohort, we identified practice areas prioritized by pharmacists for continuing and professional development. Time and cost were common barriers to education, both in developing and developed countries. These survey findings may help to guide future education initiatives of International Society of Oncology Pharmacy Practitioners and other providers of pharmacist oncology education.

Cancer-related cognitive impairment in patients with non-central nervous system malignancies: an overview for oncology providers from the MASCC Neurological Complications Study Group.

Cancer-related cognitive impairment (CRCI) is commonly experienced by individuals with non-central nervous system cancers throughout the disease and treatment trajectory. CRCI can have a substantial impact on the functional ability and quality of life of patients and their families. To mitigate the impact, oncology providers must know how to identify, assess, and educate patients and caregivers. The objective of this review is to provide oncology clinicians with an overview of CRCI in the context of adults with non-central nervous system cancers, with a particular focus on current approaches in its identification, assessment, and management.

A study protocol for HEalth-Related quality of life-intervention in survivors of Breast and other cancers experiencing cancer-related fatigue using TraditionAL Chinese Medicine: the HERBAL trial.

BACKGROUND: Cancer-related fatigue (CRF) is a debilitating condition which commonly affects cancer survivors. The management of CRF remains a challenge due to the lack of effective pharmacological interventions. Traditional Chinese medicine (TCM) could be a potential therapeutic option for CRF. The modified Xiang Bei Yang Rong Tang (XBYRT) is a TCM herbal decoction, formulated to improve fatigue symptoms in cancer survivors. This clinical trial aims to evaluate the efficacy and safety of XBYRT in improving CRF and quality of life (QOL) of cancer survivors. METHODS: This is a single centre, randomized, double-blind, placebo-controlled, parallel trial. Eighty cancer survivors will be recruited and randomized to receive the XBYRT or placebo decoction, in a ratio of 1:1. Participants will consume the XBYRT/placebo decoction daily for 8 weeks and undergo assessments at baseline and 4, 8 and 10 weeks after baseline. The participants will be assessed for patient-reported outcomes (PRO), blood biomarkers and adverse events at each time point. The primary outcome is the overall health and QOL status, at 8 weeks follow-up. The secondary outcomes are the effects of XBYRT on fatigue levels, cancer-related cognitive impairment and QOL, as assessed by PRO. The incidence of adverse events and the effects of the XBYRT decoction on blood biomarkers associated with CRF will also be evaluated. DISCUSSION: Efficacy and safety outcomes from this trial will provide important clinical data to guide future large-scale randomized controlled trials, and the evaluation of the objective blood biomarkers can help to delineate the biological mechanisms of CRF.

Associations of plasma brain-derived neurotrophic factor (BDNF) and Val66Met polymorphism (rs6265) with long-term cancer-related cognitive impairment in survivors of breast cancer.

PURPOSE: Brain-derived neurotrophic factor (BDNF) and the BDNF Val66Met polymorphism (rs6265) have been implicated in neurodegenerative conditions. This study aimed to investigate the associations of plasma BDNF and rs6265 with cancer-related cognitive impairment (CRCI) at the end of chemotherapy, and with persistent and delayed CRCI up to 24 months post chemotherapy, among survivors of early-stage breast cancer. METHODS: A multicenter, longitudinal study involving 174 breast cancer patients was conducted. CRCI was assessed using the FACT-Cog (V3) questionnaire and the CANTAB software. Plasma BDNF levels were quantified using an enzyme-linked immunosorbent assay at serial time points and genotyping was achieved using Sanger sequencing. The associations of BDNF and rs6265 with CRCI were analyzed using logistic regressions. RESULTS: A smaller magnitude of reduction in plasma BDNF between baseline and the end of chemotherapy was correlated with protection from overall subjective CRCI (OR 0.88; 95% CI 0.79-0.99). Furthermore, patients with higher plasma BDNF levels at the end of chemotherapy had lower odds of developing persistent overall subjective CRCI (OR 0.74; 95% CI 0.57-0.97) and persistent CRCI in the functional interference domain (OR 0.62; 95% CI 0.39-0.98). BDNF Met allele carriers were protected against subjective CRCI at the end of chemotherapy in the multitasking and memory domains, and against persistent subjective CRCI in the mental acuity and multitasking domains. CONCLUSION: BDNF plasma level or rs6265 genotype information may facilitate the identification of patients at higher risk of long-term CRCI during survivorship and enable the implementation of early intervention strategies that increase BDNF levels.
