Patient characteristics and treatment patterns of patients with locally advanced or metastatic HER2-low breast cancer, a single site descriptive study.

PURPOSE: To evaluate the prevalence and characteristics of different HER2 categories among patients with advanced breast cancer (aBC) and describe treatment patterns and outcomes of those with HER2-low disease. METHODS: A retrospective cohort study was conducted via chart review at the Huntsman Cancer Institute, including patients diagnosed with aBC (stages IIIB, IIIC and IV) between 2010 and 2019. All patients with IHC1+ were considered HER2-low unless FISH was positive. Patients with IHC2+ were only classified as HER2-low if a negative FISH was documented. The prevalence and characteristics of each HER2 category were reported. Treatment patterns and survival outcomes of HER2-low patients who received first line treatment in 2017 or later were presented. RESULTS: A total of 240 of 414 patients (58%) with aBC were HER2-low, with the majority of patients (83%) classified as hormone receptor (HR)-positive. In first line, most HR-positive patients received endocrine therapy with chemotherapy for stage IIIB/IIIC (47%) and with CDK4/6 inhibitors for stage IV breast cancer (50%) Most HR-negative patients received chemotherapy alone (92% for stage IIIB/IIIC, 60% for stage IV). In second line, chemotherapy alone was the most common modality (21.4% for HR-positive; 45.5% for HR-negative). Median overall survival was 37.7 months while median progression-free survival from first line was 18.0 months, decreasing to 8.0 months in second line. CONCLUSION: A substantial proportion of patients previously classified as HER2-negative have low but detectable HER2 expression and may benefit from novel HER2-directed agents, which have demonstrated clinical benefit in this population post-chemotherapy.

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.

A Systematic Literature Review of Gaps and Challenges in Value Assessment of Biosimilars: An ISPOR Special Interest Group Report.

OBJECTIVES: This study aims to provide an overview of the gaps and challenges in the value assessment of biosimilars and to identify potential approaches to address them. METHODS: A multidisciplinary, international team of biosimilar experts identified gaps and challenges. A systematic review was conducted of the peer-reviewed literature in PubMed, EMBASE, Web of Science Core Collection, EBSCOhost Business Source Complete; and of the gray literature. Preliminary results were presented at ISPOR conferences and this article benefited from 2 review rounds among ISPOR Biosimilar Special Interest Group members. RESULTS: Given that a biosimilar is highly similar to its reference biologic, health technology assessment agencies should accept the comparability exercise approved by regulatory authorities and, thus, conduct a price comparison when biosimilar reimbursement is requested for the same indication as the reference biologic. If the reference biologic is not reimbursed or is not the standard of care, a full economic evaluation of the biosimilar versus a relevant comparator needs to be conducted. To date, little consideration has been given to specific challenges, such as how biosimilar value assessment can account for the nocebo effect, potential differences between biologic-naive and biologic-experienced patients, the availability of intravenous and subcutaneous administration forms or different administration devices for the same active compound, value-added services, and the contribution of biosimilars for generating health gain at the population level. CONCLUSIONS: There is a need to gather further insights in the methodology of value assessment for biosimilars, and health technology assessment agencies need to develop more elaborate guidance on biosimilar value assessment in specific circumstances.

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.

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.

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.

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.

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.

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.

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.

Self-reported cognitive outcomes among adolescent and young adult patients with noncentral nervous system cancers.

OBJECTIVE: Cancer-related cognitive impairment (CRCI) among adolescent and young adult (AYA) cancer patients with noncentral nervous system (CNS) cancers has not been well studied. In this study, we aimed to describe CRCI-associated trends and characteristics among AYA cancer patients. METHODS: In a longitudinal cohort of AYA cancer patients without CNS disease, CRCI was evaluated over 1 year using the Functional Assessment of Cancer Therapy-Cognitive Function Instrument, a self-reported cognitive outcome measure. CRCI prevalence was quantified using the previously established minimal clinically important difference. CRCI-associated longitudinal trends and factors were evaluated with mixed-effects model analysis. RESULTS: Ninety-one patients (mean age = 28.4 ± 6.7 years) were included. Approximately one-third (34.1%) experienced CRCI at least once during the study follow-up. Female gender (P = .02), Indian ethnicity (P < .01), current smokers (P < .01), anxiety/depressive symptoms (P < .01) and fatigue (P < .01) were found to be associated with poorer cognitive function among AYAs. CONCLUSIONS: Although AYA cancer patients were relatively young and without CNS disease involvement, a significant proportion of them experienced clinically important decline in cognitive function. With improved understanding of this subject, effective strategies can be formulated to promote awareness of CRCI and mitigate its negative effects among AYA cancer patients.

A longitudinal analysis of phenotypic and symptom characteristics associated with inter-individual variability in employment interference in patients with breast cancer.

PURPOSE: A breast cancer diagnosis has a substantial economic impact. Study aims were to evaluate for inter-individual differences in cancer's level of interference with employment and identify phenotypic and symptom characteristics associated with higher levels of interference. METHODS: Patients (n = 387) were enrolled prior to breast cancer surgery and followed for 12 months. Interference with employment was measured using a 0 (no problem) to 10 (severe problem) numeric rating scale. Hierarchical linear modeling (HLM) was used to evaluate for inter-individual differences in trajectories of employment interference and characteristics associated with employment interference 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 employment interference score was 3.2 (±3.7). Unconditional model for employment interference demonstrated a decreasing linear trend (-.076/month). Younger age, lower income, higher pain intensity, and having an axillary lymph node dissection were associated with higher pre-surgical interference scores. Having a sentinel lymph node biopsy was associated with ongoing employment interference scores. Higher sleep disturbance scores were associated with both initial and ongoing employment interference scores. Receipt of chemotherapy, use of complementary or alternative therapies, and re-excision or mastectomy following surgery were significant time varying covariates. CONCLUSION: This study is the first to use HLM to describe inter-individual differences in the trajectories of cancer's interference with employment and associated factors prior to and for 12 months following breast cancer surgery. Patients with the identified risk factors warrant ongoing assessments of employment interference and appropriate referrals.

Work- and insurance-related issues among Asian adolescent and young-adult cancer survivors: a qualitative study.

PURPOSE: Work-related issues among Asian adolescent and young-adult (AYA) cancer survivors are poorly described in the literature. There has also been a paucity of reports regarding insurance-related concerns in this patient population. Focus groups were therefore carried out in Singapore to understand survivorship issues related to work and insurance coverage among Asian AYA cancer survivors. METHODS: Twenty-three AYA survivors and 18 healthcare professionals (HCPs) who care for AYA cancer patients were recruited for 11 focus group sessions. Thematic content analysis was carried out to identify major themes that emerged. RESULTS: Similar themes emerged from AYA and HCP focus groups. The majority of AYA survivors were eager to return to work post-treatment. However, some survivors were worried about not keeping up with expectations and struggled with disclosure of their medical history. In contrast, several survivors leveraged on their experience with cancer to bolster job opportunities. Despite facing challenges due to complications from cancer and restrictions at work, AYA survivors preferred to be treated normally. AYA survivors also expressed concerns about inadequate insurance coverage and a lack of information on this topic. CONCLUSION: Contrary to expectations, Asian AYA survivors are motivated to return to work and address work-related challenges. Inadequate insurance coverage remains a pressing concern despite the availability of public health insurance and subsidies. Career coaches and financial counselors should be incorporated into survivorship care to aid AYA survivors.

Proceedings of the biosimilars workshop at the International Symposium on Oncology Pharmacy Practice 2019.

The International Society of Oncology Pharmacy Practitioners organized a workshop to create learning opportunities on biosimilars in pharmacy practice on 10 October 2019. The topics that were covered included (i) the development and testing of biosimilars, (ii) the challenges of bringing biosimilars to market, and (iii) real-world data on patient safety and perceptions during biosimilar implementation. The development of biosimilars can take up to eight years and the extensiveness of the process depends on several factors, such as the complexity of the production process and regulatory requirements. Compared to generic products of small-molecule drugs, there is a higher barrier to market entry for biosimilars, explaining the small number of biosimilars in the market. Appraisal of biosimilars for inclusion in hospital formularies is also different from the review process of originator biologics, where the former is usually institution-led and has fewer restrictions on use. When several biosimilar products are available, factors that should be considered besides cost are licensed indications, supply chain confidence, clinical data, and product attributes. Real-world data have shown that biosimilars are well-tolerated and have safety data that are comparable to that of the originator product. Oncology pharmacists from the United Kingdom, Kenya, and Canada also presented their respective experiences with biosimilar use. Different countries at varying stages of biosimilar implementation faced distinct challenges. Nevertheless, resources to assist biosimilar implementation can potentially be shared between different regions. International Society of Oncology Pharmacy Practitioners is well-positioned to foster professional cooperation at an international level to drive biosimilar implementation.

Role of Exosomes in Cancer-Related Cognitive Impairment.

A decline in cognitive function following cancer treatment is one of the most commonly reported post-treatment symptoms among patients with cancer and those in remission, and include memory, processing speed, and executive function. A clear understanding of cognitive impairment as a result of cancer and its therapy can be obtained by delineating structural and functional changes using brain imaging studies and neurocognitive assessments. There is also a need to determine the underlying mechanisms and pathways that impact the brain and affect cognitive functioning in cancer survivors. Exosomes are small cell-derived vesicles formed by the inward budding of multivesicular bodies, and are released into the extracellular environment via an exocytic pathway. Growing evidence suggests that exosomes contribute to various physiological and pathological conditions, including neurological processes such as synaptic plasticity, neuronal stress response, cell-to-cell communication, and neurogenesis. In this review, we summarize the relationship between exosomes and cancer-related cognitive impairment. Unraveling exosomes' actions and effects on the microenvironment of the brain, which impacts cognitive functioning, is critical for the development of exosome-based therapeutics for cancer-related cognitive impairment.

Association of plasma leptin, pro-inflammatory adipokines and cancer-related fatigue in early-stage breast cancer patients: A prospective cohort study.

Cancer-related fatigue (CRF) is subjective and has wide inter-individual variability. Given that leptin is commonly associated with fatigue syndrome, its use as a potential biomarker for CRF is being investigated. The primary objective of this study was to evaluate the association between leptin and CRF in early-stage breast cancer patients receiving chemotherapy. In a prospective cohort study, patients completed assessments at baseline (T1), during chemotherapy (T2) and after chemotherapy (T3). Levels of plasma leptin and adipokines were measured using a Luminex bead-immunoassay and CRF was measured using the Multi-Dimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Data were analysed longitudinally using a generalised estimating equation incorporating clinically relevant parameters and pro-inflammatory adipokines. The analysis included 136 patients (mean age ± SD = 51.5 ± 8.8 years; 69.1% receiving anthracycline-based chemotherapy). More patients experienced CRF at T3 (23.8%) than at T2 (13.8%) compared to baseline. An increase was observed in the median plasma leptin level at T2, followed by a decrease at T3 (T1: 4.07 ng/mL, T2: 4.95 ng/mL and T3: 3.96 ng/mL). In the multivariate model, the change in leptin levels over time was significantly associated with the total MFSI-SF score (ß = -0.15, P = 0.003) after adjusting for the tumour necrosis factor-α (TNF-α) level, anxiety, depression, insomnia, age, menopausal status and type of chemotherapy. This is the first study to report leptin as a biomarker that predicts the onset of CRF over time. Future studies are required to validate the findings.

Biological predictors of chemotherapy-induced peripheral neuropathy (CIPN): MASCC neurological complications working group overview.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating condition associated with a number of chemotherapeutic agents. Drugs commonly implicated in the development of CIPN include platinum agents, taxanes, vinca alkaloids, bortezomib, and thalidomide analogues. As a drug response can vary between individuals, it is hypothesized that an individual's specific genetic variants could impact the regulation of genes involved in drug pharmacokinetics, ion channel functioning, neurotoxicity, and DNA repair, which in turn affect CIPN development and severity. Variations of other molecular markers may also affect the incidence and severity of CIPN. Hence, the objective of this review was to summarize the known biological (molecular and genomic) predictors of CIPN and discuss the means to facilitate progress in this field.

Assessment of psychological distress among Asian adolescents and young adults (AYA) cancer patients using the distress thermometer: a prospective, longitudinal study.

PURPOSE: Since few studies have investigated whether the Distress Thermometer (DT) in Asian adolescent and young adult (AYA) cancer patients (between 15 and 39 years), we investigated the appropriateness of the DT as a screening tool for psychological symptom burden in these AYA patients and to evaluate AYA patients' distress across a trajectory of three time points longitudinally over a 6-month period. METHODS: This was a prospective, longitudinal study. Recruited Asian AYA patients were diagnosed with lymphomas, sarcomas, primary brain malignancies, or germ cell tumors. Patients completed the DT, PedsQL Generic Core Scales, and the Rotterdam Symptom Checklist. Data were analyzed using STATA version 15. RESULTS: Approximately half of the patients experienced clinically significant DT distress (distress score ≥ 4) early in their cancer journey with 43.1% patients presenting with distress at time of diagnosis and 47.7% patients 1 month after diagnosis. Among AYA patients > 24 years old, worry (68.3%), insurance/financial issues (61%), treatment decisions (43.9%), work/school issues (41.5%), nervousness (41.5%), and sadness (41.5%) were the top five identified problems. On the other hand, the top five identified problems among AYA ≤ 24 years were worry (54.2%), nervousness (41.7%), bathing/dressing problems (37.5%), work/school issues (33.3%), and fatigue (33.3%). DT scores were significantly associated with certain psychological symptom burden items such as worry (p < 0.001), depressed mood (p = 0.020), and nervousness (p = 0.015). CONCLUSION: The DT is a useful screening tool for psychological distress in AYA cancer patients with clinically significant distress being identified in the early phases of the cancer journey.

Efficacy and Effectiveness Outcomes of Treatments for Double-Exposed Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma Patients: A Systematic Literature Review.

BACKGROUND: Bruton's tyrosine kinase inhibitors (BTKi) and the B-cell lymphoma 2 (BCL2) inhibitor venetoclax have significantly improved outcomes and achieved durable remission in patients with chronic lymphocytic leukemia (CLL). BTKi/venetoclax-treated patients with exposure to both novel agents (regardless of the reason for discontinuation) are classified as "double-exposed," and often have poor prognoses. This study aims to assess the efficacy and effectiveness of treatments in double-exposed CLL patients. METHODS: PubMed, Embase, and Web of Science databases were searched until December 2023. RESULTS: We retrieved 3948 articles for screening and included 13 publications covering nine distinct studies. Three clinical trials reported a median PFS of 16.8 months with pirtobrutinib, 13 months with lisocabtagene maraleucel, and 10.1 months with nemtabrutnib. ORR ranged from 58% with nemtabrutinib and 80% with lisocabtagene maraleucel. In observational studies, PFS ranged from 3 months with chemoimmunotherapy to 12 months with BTKi, and ORR ranged from 31.8% with chemoimmunotherapy to 85.7% with chimeric antigen receptors (CAR) T-cell therapy. CONCLUSION: This study highlights the limited clinical data on efficacy outcomes for double-exposed CLL/SLL patients. Pirtobrutinib, lisocabtagene maraleucel, and a combination of ibrutinib and venetoclax have shown promising effects. However, the scarcity of treatment options and efficacy data for patients who have failed BTKi and venetoclax underscores a significant unmet medical need.

Modeling the population health impact of incorporating a multi-cancer early detection (MCED) test to existing cancer screening among immunocompromised individuals.

OBJECTIVE: To assess the screening efficiency of an multi-cancer early detection (MCED) test added to standard of care (SoC) screening, compared to SoC screening alone, among immunocompromised individuals, and to estimate the diagnostic workup costs associated with positive screening results. METHODS: We estimated the potential impact of cancer screening among immunocompromised individuals aged 50-79 years within the University of Utah Health system who underwent a stem cell/solid organ transplant or were diagnosed with a primary or secondary immunodeficiency disorder between January 2000 and February 2018. We derived cancer incidence rates from the Huntsman Cancer Institute Tumor Registry, and screening performance of SoC screening and an MCED test from published literature. Outcomes of screening efficiency included the true-positive to false-positive (TP:FP) ratio, diagnostic yield (DY), and cancer detection rate (CDR) for SoC screening alone and an incremental MCED test. Scenario and probabilistic sensitivity analyses were conducted. RESULTS: Among 4932 immunocompromised individuals aged 50-79 years, we estimated that 2595 tests would be done under SoC screening and assumed that all individuals received an additional MCED test. Adding an MCED test to SoC screening substantially improved screening efficiency (TP:FP = 1:1, DY = 5.15/1000 tests, CDR = 42.0%), compared to SoC screening alone (TP:FP = 1:99, DY = 1.23/1000 tests, CDR = 5.3%), assuming an MCED test with 100% uptake. Our findings were also robust to parameter uncertainty. CONCLUSION: Adding an MCED test to complement existing screening may be a highly efficient strategy to increase the detection of cancers among immunocompromised individuals. These results could help to improve cancer prevention and detection efforts among individuals with multiple cancer risk factors.
