A systematic review and meta-analysis of observational studies and uncontrolled trials reporting on the use of checkpoint blockers in patients with cancer and pre-existing autoimmune disease.

BACKGROUND: Cancer patients with autoimmune disease have been excluded from randomized trials of immune checkpoint blockers (ICBs). We conducted a systematic review of observational studies and uncontrolled trials including cancer patients with pre-existing autoimmune disease who received ICBs. METHODS: We searched 5 electronic databases through November 2023. Study selection, data collection, and quality assessment were performed independently by 2 investigators. We performed a meta-analysis to pool incidence of immune-related adverse events (irAEs), including de novo events and flares of existing autoimmune disease, hospitalizations due to irAEs, as well as deaths. RESULTS: A total of 95 studies were included (23,897 patients with cancer and preexisting autoimmune disease). The most common cancer evaluated was lung cancer (30.7 %) followed by skin cancer (15.7 %). Patients with autoimmune disease were more likely to report irAEs compared to patients without autoimmune disease (relative risk 1.3, 95 % CI 1.0 to 1.6). The pooled occurrence rate of any irAEs (flares or de novo) was 61 % (95 % CI 54 % to 68 %); that of flares was 36 % (95 % CI 30 % to 43 %), and that of de novo irAEs was 23 % (95 % CI 16 % to 30 %). Flares were mild (grade <3) in half of cases and more commonly reported in patients with psoriasis/psoriatic arthritis (39 %), inflammatory bowel disease (37 %), and rheumatoid arthritis (36 %). 32 % of the patients with irAEs required hospitalization and treatment of irAEs included corticosteroids in 72 % of the cases. The irAEs mortality rate was 0.07 %. There were no statistically significant differences in cancer response to ICBs between patients with and without autoimmune disease. CONCLUSIONS: Although more patients with pre-existing autoimmune disease had irAEs, these were mild and managed with corticosteroids in most cases, with no impact on cancer response. These results suggest that ICBs can be used in these patients, but careful monitoring is required, as over a third of the patients will experience a flare of their autoimmune disease and/or require hospitalization. These findings provide a crucial foundation for oncologists to refine their monitoring and management strategies, ensuring that the benefits of ICB therapy are maximized while minimizing its risks.

Assessment of Glomerular Filtration Rate in Patients with Cancer: A Statement from the American Society of Onco-Nephrology.

Accurate assessment of glomerular filtration rate (GFR) is crucial to guiding drug eligibility, dosing of systemic therapy, and minimizing the risks of both undertreatment and toxicity in patients with cancer. Up to 32% of cancer patients have baseline chronic kidney disease (CKD), and both malignancy and treatment may cause kidney injury and subsequent CKD. To date, there has been lack of guidance to standardize approaches to GFR estimation in the cancer population. In this two-part statement from the American Society of Onco-Nephrology, we present key messages for estimation of GFR in patients with cancer, including the choice of GFR estimating equation, use of race and body surface-area (BSA)-adjustment, and anticancer drug dose-adjustment in the setting of CKD. These key messages are based on a systematic review of studies assessing GFR estimating equations using serum creatinine and cystatin C in patients with cancer, against a measured GFR comparator. The preponderance of current data involving validated GFR estimating equations involves the CKD-EPI equations, with 2,508 patients in whom CKD-EPI using serum creatinine and cystatin C was assessed (8 studies) and 15,349 in whom CKD-EPI with serum creatinine was assessed (22 studies). The former may have improved performance metrics and be less susceptible to shortfalls of eGFR using serum creatinine alone. Since included studies were moderate quality or lower, the ASON Position Committee rated the certainty of evidence as low. Additional studies are needed to assess the accuracy of other validated eGFR equations in patients with cancer. Given the importance of accurate and timely eGFR assessment we advocate for the use of validated GFR estimating equations incorporating both serum creatinine and cystatin C in patients with cancer. Measurement of GFR via exogenous filtration markers should be considered in patients with cancer for whom eGFR results in borderline eligibility for therapies or clinical trials.

Characteristics and Outcomes of Stem Cell Transplant Patients during the COVID-19 Era: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aims to identify the outcomes of stem cell transplant (SCT) patients during the COVID-19 era. Pooled event rates (PER) were calculated, and meta-regression was performed. A random effects model was utilized. In total, 36 eligible studies were included out of 290. The PER of COVID-19-related deaths and COVID-19-related hospital admissions were 21.1% and 55.2%, respectively. The PER of the use of hydroxychloroquine was 53.27%, of the receipt of immunosuppression it was 39.4%, and of the use of antivirals, antibiotics, and steroids it was 71.61%, 37.94%, and 18.46%, respectively. The PER of the time elapsed until COVID-19 infection after SCT of more than 6 months was 85.3%. The PER of fever, respiratory symptoms, and gastrointestinal symptoms were 70.9, 76.1, and 19.3%, respectively. The PER of acute and chronic GvHD were 40.2% and 60.9%, respectively. SCT patients are at a higher risk of severe COVID-19 infection and mortality. The use of dexamethasone improves the survival of hospitalized SCT patients with moderate to severe COVID-19 requiring supplemental oxygen or ventilation. The SCT patient group is a heterogeneous group with varying characteristics. The quality of reporting on these patients when infected with COVID-19 is not uniform and further prospective or registry studies are needed to better guide clinical care in this unique setting.

Interventions to increase follow-up of abnormal cervical cancer screening results: A systematic literature review and meta-analysis.

INTRODUCTION: Ensuring timely follow-up of abnormal screening results is essential for eliminating cervical cancer. OBJECTIVE: The purpose of the study was to review single and multicomponent interventions designed to improve follow-up of women with abnormal cervical cancer screening results. We report on effectiveness across studies, and describe what aspects of these interventions might be more impactful. METHODS: Publications were searched between January 2000 and December 2022. The search included observational, quasi-experimental (pre-post studies) and randomized controlled studies describing at least one intervention to increase follow-up of women with abnormal cervical cancer screening results. Outcomes of studies included completion of any follow-up (i.e., attending a follow-up appointment), timely diagnosis (i.e., colposcopy results within 90 days of screening) and time to diagnostic resolution (i.e., days between screening and final diagnosis). We assessed risk of bias for observational and quasi-experimental studies using the Newcastle-Ottawa Scale (NOS) tool and the Cochrane collaboration tool for randomized studies. We conducted a meta-analysis using studies where data were provided to estimate a summary average effect of the interventions on follow-up of patients and to identify characteristics of studies associated with an increased effectiveness of interventions. We extracted the comparison and intervention proportions of women with follow-up before and after the intervention (control and intervention) and plotted the odds ratios (ORs) of completing follow-up along with the 95% confidence intervals (CIs) using forest plots for the interventions vs. controls when data were available. FINDINGS: From 7,457 identified studies, 28 met the inclusion criteria. Eleven (39%) of the included studies had used a randomized design. Most studies (63%) assessed completion of any follow-up visit as the primary outcome, whereas others measured time to definite diagnosis (15%) or diagnostic resolution (22%). Navigation was used as a type of intervention in 63% of the included studies. Most interventions utilized behavioral approaches to improve outcomes. The overall estimate of the OR for completion of follow-up for all interventions was 1.81 (1.36-2.42). The highest impact was for programs using more than one approach (multicomponent interventions) to improve outcomes with OR = 3.01 (2.03-4.46), compared with studies with single intervention approaches with OR = 1.56 (1.14-2.14). No statistical risks were noted from publication bias or small-study effects in the studies reviewed. CONCLUSION: Our findings revealed large heterogeneity in how follow-up of abnormal cervical cancer screening results was defined. Our results suggest that multicomponent interventions were more effective than single component interventions and should be used to improve follow-up after abnormal cervical cancer screening results. Navigation appears to be an important tool for improving follow-up. We also provide recommendations for future studies and implications for policy in terms of better defining outcomes for these interventions.

Oral Toxicities Associated with Immune Checkpoint Inhibitors: Meta-Analyses of Clinical Trials.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment; however, their oral toxicity profile is not well elucidated. This review aimed to investigate the prevalence of oral toxicities including xerostomia, mucositis/stomatitis, dysgeusia, dysphagia, oral/oropharyngeal pain, oral infections, angular cheilitis, osteonecrosis, osteomyelitis, and oral mucosal reactions with ICIs. A review protocol was registered with PROSPERO (ID: CRD42023391674). A systematic search of ClinicalTrials.gov was conducted as of April 10, 2022. Studies were selected, assessed, and data extracted using PRISMA guidelines. Oral toxicity data were extracted from study arms using a single immunotherapy drug. Meta-analyses were conducted to summarize prevalence of oral toxicities using random-effects models. Of 750 screened records, 95 trials were included in the meta-analysis with published results. Time between study completion and first publication on ClinicalTrials.gov was 1 to 146 months (mean = 20.3, SD = 18.4). Weighted pooled prevalence was 5% (95% CI: 4-6%) for xerostomia, 3% (95% CI: 3-4%) for mucositis/stomatitis, 3% (95% CI: 2-3%) for dysgeusia, 2% (95% CI: 1-2%) for dysphagia, 3% (95% CI: 2-4%) for oropharyngeal/oral pain, 2% (95% CI: 1-3%) for oral candidiasis, and 2% (95% CI: 0-4%) for angular cheilitis. Subgroup differences based on ICI drugs were minimal. No trials reported lichenoid or pemphigoid mucosal reactions. Meta-analysis results revealed low prevalence of oral toxicities with ICIs; however, data reporting was limited and inconsistent. Limitations of study dataset reveal a significant need for systematic collection of oral morbidity data as well as improved consistency and compliance of reporting results on ClinicalTrials.gov.

A systematic review of endometrial cancer clinical research in Africa.

BACKGROUND: Women in Africa are experiencing a rising burden of endometrial cancer. Research and investment to improve treatment and outcomes are critically needed. We systematically reviewed and characterized endometrial cancer-related research within a clinically relevant context to help organize and assess existing endometrial cancer research in Africa. METHODS: According to PRISMA guidelines, we searched online databases for published endometrial cancer articles from African countries from January 1, 2011, to July 20, 2021. Based on our inclusion and exclusion criteria, independent reviewers documented the study design, country/region, human development index, focus of research, type of interventions performed, and histologic and molecular type to illustrate the breadth of research coverage in each region. RESULTS: A total of 18 research articles were included. With an average Human Development Index (HDI) in Africa of 0.536, the average HDI of the represented countries in this study was 0.709. The majority (88.9%) of prospective endometrial cancer research articles in Africa were from North Africa, with Egypt encompassing 83.3% of the papers. Most of these studies focused on endometrial cancer diagnosis. Research on the treatment of endometrial cancer is still emerging (33% of papers). Of all included articles, only 11.1% represented Sub-Saharan Africa, where the majority population of black Africans reside. CONCLUSIONS: Endometrial cancer research in Africa is extremely limited, with the majority being concentrated in African countries with higher HDIs. As the incidence of endometrial cancer rises in Sub-Saharan Africa, there is a pressing need for more prospective clinical research to tackle the growing disease burden and improve outcomes.

Artificial Intelligence and Machine Learning in Cancer Related Pain: A Systematic Review.

Background/objective: Pain is a challenging multifaceted symptom reported by most cancer patients, resulting in a substantial burden on both patients and healthcare systems. This systematic review aims to explore applications of artificial intelligence/machine learning (AI/ML) in predicting pain-related outcomes and supporting decision-making processes in pain management in cancer. Methods: A comprehensive search of Ovid MEDLINE, EMBASE and Web of Science databases was conducted using terms including "Cancer", "Pain", "Pain Management", "Analgesics", "Opioids", "Artificial Intelligence", "Machine Learning", "Deep Learning", and "Neural Networks" published up to September 7, 2023. The screening process was performed using the Covidence screening tool. Only original studies conducted in human cohorts were included. AI/ML models, their validation and performance and adherence to TRIPOD guidelines were summarized from the final included studies. Results: This systematic review included 44 studies from 2006-2023. Most studies were prospective and uni-institutional. There was an increase in the trend of AI/ML studies in cancer pain in the last 4 years. Nineteen studies used AI/ML for classifying cancer patients' pain development after cancer therapy, with median AUC 0.80 (range 0.76-0.94). Eighteen studies focused on cancer pain research with median AUC 0.86 (range 0.50-0.99), and 7 focused on applying AI/ML for cancer pain management decisions with median AUC 0.71 (range 0.47-0.89). Multiple ML models were investigated with. median AUC across all models in all studies (0.77). Random forest models demonstrated the highest performance (median AUC 0.81), lasso models had the highest median sensitivity (1), while Support Vector Machine had the highest median specificity (0.74). Overall adherence of included studies to TRIPOD guidelines was 70.7%. Lack of external validation (14%) and clinical application (23%) of most included studies was detected. Reporting of model calibration was also missing in the majority of studies (5%). Conclusion: Implementation of various novel AI/ML tools promises significant advances in the classification, risk stratification, and management decisions for cancer pain. These advanced tools will integrate big health-related data for personalized pain management in cancer patients. Further research focusing on model calibration and rigorous external clinical validation in real healthcare settings is imperative for ensuring its practical and reliable application in clinical practice.

Systematic Review of Genetic Polymorphisms Associated with Acute Pain Induced by Radiotherapy for Head and Neck Cancers.

Background/objective: Pain is the most common acute symptom following radiation therapy (RT) for head and neck cancer (HNC). The multifactorial origin of RT-induced pain makes it highly challenging to manage. Multiple studies were conducted to identify genetic variants associated with cancer pain, however few of them focused on RT-induced acute pain. In this review, we summarize the potential mechanisms of acute pain after RT in HNC and identify genetic variants associated with RT-induced acute pain and relevant acute toxicities. Methods: A comprehensive search of Ovid Medline, EMBASE and Web of Science databases using terms including "Variants", "Polymorphisms", "Radiotherapy", "Acute pain", "Acute toxicity" published up to February 28, 2022, was performed by two reviewers. Review articles and citations were reviewed manually. The identified SNPs associated with RT-induced acute pain and toxicities were reported, and the molecular functions of the associated genes were described based on genetic annotation using The Human Gene Database; GeneCards. Results: A total of 386 articles were identified electronically and 8 more articles were included after manual search. 21 articles were finally included. 32 variants in 27 genes, of which 25% in inflammatory/immune response, 20% had function in DNA damage response and repair, 20% in cell death or cell cycle, were associated with RT-inflammatory pain and acute oral mucositis or dermatitis. 4 variants in 4 genes were associated with neuropathy and neuropathic pain. 5 variants in 4 genes were associated with RT-induced mixed types of post-RT-throat/neck pain. Conclusion: Different types of pain develop after RT in HNC, including inflammatory pain; neuropathic pain; nociceptive pain; and mixed oral pain. Genetic variants involved in DNA damage response and repair, cell death, inflammation and neuropathic pathways may affect pain presentation post-RT. These variants could be used for personalized pain management in HNC patients receiving RT.

Prevalence of Adverse Event Reporting in Adolescents and Young Adults Enrolled in Cancer Clinical Trials.

PURPOSE: Survival for adolescents and young adults (AYAs) with cancer has improved over the past few decades, and targeted approaches are needed to further improve outcomes. Limited reports suggest that AYAs tolerate cancer treatment differently than older and younger patients. Lack of adverse event (AE) data prevents the optimization of treatment regimens for AYAs by maximizing drug delivery and minimizing treatment-related toxicity. The extent to which the frequency and severity of AEs are reported for AYAs in cancer trials is unknown. METHODS: Using a retrospective, observational design we reviewed all phase II/III clinical trials published in 2021 that included cancer-directed therapy and enrolled at least one patient age 15-39 years diagnosed with one of the five common AYA cancers: breast cancer, colorectal cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, or melanoma. The primary outcome was to determine the proportion of phase II/III trials that report AEs for the AYA population. RESULTS: Of 2,540 publications identified, 182 were included in the final analysis. No studies reported AE data for AYAs separate from older adults. Given the lack of reporting of AEs by age, it was not possible to assess differences in AE frequency or severity or whether AEs were associated with differences in dose reductions, treatment delays, or discontinuation for AYAs. CONCLUSION: Reporting of AEs for AYAs with cancer is absent in the public domain. Failure to account for differences in treatment tolerance between AYAs and older adults may lead to undertreatment or overtreatment and delay progress toward further improving outcomes for AYAs.

Disparities in cancer care among sexual and gender minority adolescent and young adult patients: A scoping review.

BACKGROUND: Adolescent and young adult cancer patients (AYAs) who are sexual and gender minorities (SGM) are a rapidly increasing population that experiences unmet cancer-related needs. Despite emerging awareness, little is known about cancer care and outcomes for this vulnerable population. The purpose of this scoping review was to explore current knowledge and gaps in the literature on cancer care and outcomes for AYAs who identify as SGM. METHODS: We reviewed empirical knowledge on SGM AYAs by identifying, describing, and critically appraising the literature to date. We conducted a comprehensive search on OVID MEDLINE, PsycINFO, and CINAHL in February 2022. Additionally, we developed and piloted a conceptual framework for appraising SGM AYA research. RESULTS: A total of 37 articles were included in the final review. Most studies focused exclusively on SGM-related outcomes as the primary aim of the study (81.1%, n = 30), whereas others included some focus on SGM-related outcomes (18.9%, n = 7). The majority of studies included AYAs as part of a broader age range (86.0%, n = 32), and only a few studies examined exclusively AYA samples (14.0%, n = 5). Gaps in scientific evidence on SGM AYAs were seen across the cancer care continuum. CONCLUSION: Numerous gaps in knowledge of cancer care and outcomes exist for SGM AYAs diagnosed with cancer. Future efforts should fill this void with high-quality empirical studies that reveal unknown disparities in care and outcomes and are inclusive of the intersectionality of SGM AYAs with other minoritized experiences, thereby advancing health equity in meaningful ways.

American Radium Society Appropriate Use Criteria for Radiation Therapy in the Multidisciplinary Management of Thymic Carcinoma.

Importance: Thymic carcinoma is rare, and its oncologic management is controversial due to a paucity of prospective data. For this reason, multidisciplinary consensus guidelines are crucial to guide oncologic management. Objective: To develop expert multidisciplinary consensus guidelines on the management of common presentations of thymic carcinoma. Evidence Review: Case variants spanning the spectrum of stage I to IV thymic carcinoma were developed by the 15-member multidisciplinary American Radium Society (ARS) Thoracic Appropriate Use Criteria (AUC) expert panel to address management controversies. A comprehensive review of the English-language medical literature from 1980 to 2021 was performed to inform consensus guidelines. Variants and procedures were evaluated by the panel using modified Delphi methodology. Agreement/consensus was defined as less than or equal to 3 rating points from median. Consensus recommendations were then approved by the ARS Executive Committee and subject to public comment per established ARS procedures. Findings: The ARS Thoracic AUC panel identified 89 relevant references and obtained consensus for all procedures evaluated for thymic carcinoma. Minimally invasive thymectomy was rated as usually inappropriate (regardless of stage) due to the infiltrative nature of thymic carcinomas. There was consensus that conventionally fractionated radiation (1.8-2 Gy daily) to a dose of 45 to 60 Gy adjuvantly and 60 to 66 Gy in the definitive setting is appropriate and that elective nodal irradiation is inappropriate. For radiation technique, the panel recommended use of intensity-modulated radiation therapy or proton therapy (rather than 3-dimensional conformal radiotherapy) to reduce radiation exposure to the heart and lungs. Conclusions and Relevance: The ARS Thoracic AUC panel has developed multidisciplinary consensus guidelines for various presentations of thymic carcinoma, perhaps the most well referenced on the topic.

Immunosuppression for the treatment of pulmonary hypertension in patients with systemic lupus erythematosus: A systematic review.

PURPOSE: To conduct a systematic review with meta-analysis to determine the effects of immunosuppression on Group 1 Pulmonary Arterial Hypertension in patients with systemic lupus erythematosus (SLE). METHODS: We searched Medline, Embase, Web of Science, Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) with a search strategy developed by a medical librarian. We included retrospective, cross-sectional, case-control, prospective studies, and randomized controlled trials (RCTs) in our analysis and only included studies that contained data for patients with SLE. We included any immunosuppressive agents (including but not limited to cyclophosphamide, glucocorticoids, mycophenolate mofetil, azathioprine, and rituximab) We assessed for risk of bias and certainty of evidence. Outcomes included hemodynamics (as measured by pulmonary arterial hypertension), functional status, 6 minute walk test (6MWT), quality of life, mortality, and serious adverse events. RESULTS: We included three studies. One RCT and two single-arm interventional observational studies. The RCT had a high risk of bias whereas the two single-arm interventional studies were graded as fair quality. Meta-analysis could not be conducted because of insufficient data. The RCT showed significant improvements in hemodynamics (as measured by pulmonary arterial pressures) and functional status. One observational study showed improvements in hemodynamics, functional status, and 6MWT. There were insufficient data for serious adverse events, mortality, and quality of life. CONCLUSIONS: Despite a high prevalence and with a poor prognosis, there is a paucity of data for the role of immunosuppression in the treatment of Group 1 Pulmonary Arterial Hypertension in SLE. More high-quality studies are needed, especially to investigate serious adverse events and quality of life.

COVID-19 Outcomes in Patients with Cancer Receiving Immune Checkpoint Inhibitors: A Systematic Review.

Introduction: Immune checkpoint inhibitors (ICIs) can cause inflammatory and immune-related adverse events (irAEs) that might worsen the course of COVID-19. We conducted a systematic review (PROSPERO ID: CRD42022307545) to evaluate the clinical course and complications of COVID-19 in patients with cancer receiving ICI. Methods: We searched Medline and Embase through January 5, 2022. We included studies evaluating patients with cancer who received ICI and developed COVID-19. Outcomes included mortality, severe COVID-19, intensive care unit (ICU) and hospital admissions, irAEs, and serious adverse events. We pooled data with random effects meta-analysis. Results: Twenty-five studies met study eligibility (n = 36,532 patients: 15,497 had COVID-19 and 3220 received ICI). Most studies (71.4%) had a high risk of comparability bias. There were no significant differences in mortality (relative risk [RR] 1.29; 95% CI 0.62-2.69), ICU admission (RR 1.20; 95% CI 0.71-2.00), and hospital admission (RR 0.91; 95% CI 0.79-1.06) when comparing patients treated with ICI with patients without cancer treatment. When pooling adjusted odds ratios (ORs), no statistically significant differences were observed in mortality (OR 0.95; 95% CI 0.57-1.60), severe COVID-19 (OR 1.05; 95% CI 0.45-2.46), or hospital admission (OR 2.02; 95% CI 0.96-4.27), when comparing patients treated with ICIs versus patients with cancer without ICI therapy. No significant differences were observed when comparing clinical outcomes in patients receiving ICIs versus patients receiving any of the other anticancer therapies. Conclusion: Although current evidence is limited, COVID-19 clinical outcomes of patients with cancer receiving ICI therapy appear to be similar to those not receiving oncologic treatment or other cancer therapies.

Controlled growth of lead-free cesium zirconium halide double perovskite nanocrystals through a microfluidic reactor.

Vacancy-ordered Cs2ZrX6 (X = Cl, Br) double perovskite nanocrystals (NCs) have recently attracted increasing attention in optoelectronic applications due to their promising photoluminescence property, high photostability, and low toxicity. However, their ultra-fast reaction limits the growth control and kinetics study of these Cs2ZrX6 NCs. Here we report the synthesis of Cs2ZrX6 NCs through a microfluidic reactor and achievement of tunable emission wavelengths by controlling the NC size and hybrid halogen ions. Reaction kinetics study reveals that the amine ligand and reaction temperature play dominate roles in the growth and optical performance of the Cs2ZrX6 NCs. The effects of flow rate, precursors, and ligand ratio on the morphology and optical property of the NCs were also investigated. This study provides an insight into the growth kinetics of the Cs2ZrX6 perovskite NCs and their continuous production through a microfluidic reactor that could facilitate the development and optical application of lead-free vacancy-ordered double perovskite NCs.

Health-related quality of life in adolescents and young adults with cancer who received radiation therapy: a scoping review.

PURPOSE: Radiation therapy (RT) is a critical component of treatment for adolescents and young adults (AYAs, age 15-39 years old) diagnosed with cancer. Limited prior studies have focused on AYAs receiving RT despite the potentially burdensome effects of RT. We reviewed the literature to assess health-related quality of life (HRQOL) in AYAs with cancer who received RT. METHODS: The MEDLINE, EMBASE, and Web of Science databases were searched in January 2022 to identify studies that analyzed HRQOL measured by patient-reported outcomes in AYAs who received RT. After title (n = 286) and abstract (n = 58) screening and full-text review (n = 19), articles that met eligibility criteria were analyzed. RESULTS: Six studies were analyzed. Two studies included AYAs actively receiving treatment and all included patients in survivorship; time between diagnosis and HRQOL data collection ranged from 3 to > 20 years. Physical and mental health were commonly assessed (6/6 studies) with social health assessed in three studies. AYA-relevant HRQOL needs were rarely assessed: fertility (1/6 studies), financial hardship (1/6), body image (0/6), spirituality (0/6), and sexual health (0/6). No study compared HRQOL between patients actively receiving RT and those post-treatment. None of the studies collected HRQOL data longitudinally. CONCLUSION: HRQOL data in AYAs receiving RT is limited. Future studies examining longitudinal, clinician- vs. patient-reported, and AYA-relevant HRQOL are needed to better understand the unique needs in this population.

COVID-19 vaccination in patients with cancer receiving immune checkpoint inhibitors: a systematic review and meta-analysis.

BACKGROUND: Immune checkpoint inhibitors (ICI) can cause off-target inflammatory and immune-related adverse events (irAE). Conceivably, COVID-19 vaccination could trigger an inflammatory and immune response that could induce or aggravate irAE. METHODS: The objective of this systematic review is to appraise the efficacy and safety of COVID-19 vaccination in patients with cancer treated with ICI. The literature search was performed in PubMed and Embase in English from December 2019 to February 2022. The review included clinical trials, observational cohort studies, case series, and case reports reporting on the clinical efficacy and safety of COVID-19 vaccines on patients with cancer treated with ICI. Outcomes of interest included seroconversion, SARS-CoV-2 infection rate, severe COVID-19, COVID-19 mortality rate. Incidence of ICI irAEs was also ascertained as well as vaccine adverse events. A meta-analysis was conducted to estimate the pooled effect sizes of the outcomes when possible, using random effects models. RESULTS: Overall, 19 studies were included for the analysis (n=10 865 with 2477 receiving ICI). We analyzed 15 cohort studies, 1 cross-sectional study, and 3 case reports. There were no statistically significant differences in seroconversion rates after the second dose of the vaccine when comparing patients with cancer receiving ICI with patients without cancer (risk ratio, RR 0.97, 95% CI 0.92 to 1.03) or with patients with cancer without active treatment (RR 1.00, 95% CI 0.96 to 1.04). There was a higher probability of seroconversion in patients with cancer treated with ICI compared with patients with cancer treated with chemotherapy (RR 1.09, 95% CI 1.00 to 1.18). In a single study in patients receiving ICI, no differences were observed in risk of irAE between those receiving inactivated vaccine and those unvaccinated (pneumonitis RR 0.88, 95% CI 0.33 to 2.3; rash RR 1.03, 95% CI 0.66 to 1.62; arthralgia RR 0.94, 95% CI 0.51 to 1.75). There were no studies for other types of vaccines comparing vaccinated vs not vaccinated in patients treated with ICI. The most common vaccine-related adverse events were local pain or fatigue. Overall, the quality of evidence was rated as very low. CONCLUSION: COVID-19 vaccination appears to be effective and safe in patients with cancer receiving ICI.

Cultural influences on shared decision-making among Asian Americans: A systematic review and meta-synthesis of qualitative studies.

OBJECTIVE: To summarize how Asian Americans negotiate involvement in shared decision-making (SDM) with their providers, the cultural influences on SDM, and perceived barriers and facilitators to SDM. METHODS: This is a systematic review of qualitative studies. We searched six electronic databases and sources of gray literature until March 2021. Two reviewers independently screened studies, performed quality appraisal, and data extraction. Meta-synthesis was performed to summarize themes using a three-step approach. RESULTS: Twenty studies with 675 participants were included. We abstracted 275 initial codes and grouped these into 19 subthemes and 4 major themes: (1) negotiating power and differing expectations in SDM; (2) cultural influences on SDM; (3) importance of social support in SDM; and (4) supportive factors for facilitating SDM. CONCLUSIONS: Asian Americans have important perspectives, needs, and preferences regarding SDM that impacts how they engage with the provider on medical decisions and their perception of the quality of their care. PRACTICE IMPLICATIONS: Asian American patients valued good communication and sufficient time with their provider, and that it is important for health professionals to understand patients' desired level of involvement in the SDM process and in the final decision, and who should be involved in SDM beyond the patient. OTHER: This systematic review was registered on PROSPERO (CRD42021241665).

Inhalation of Isopropyl Alcohol for the Management of Nausea and Vomiting: A Systematic Review.

Background: The use of inhaled isopropyl alcohol (IPA) has been proposed as a therapeutic intervention for the relief of nausea in various settings. The objective of this systematic review was to evaluate the existing evidence for the use of inhaled IPA in the management of nausea and vomiting. Methods: We performed a literature search on Medline, EMBASE, Web of Science, Scopus, CINAHL, PsycInfo, and Cochrane Library databases before November 2021. The following concepts were searched using subject headings and keywords as needed "aromatherapy," "alcohol," "ethylic alcohol," "ethanol," "isopropyl alcohol," "emesis," "chemotherapy-induced," "pregnancy," "hyperemesis gravidarum," "motion sickness," "emetics," "antiemetics," "inhalation," and "inhale." Searches were not limited to a specific language. The bibliographies of identified articles were also manually searched. Two authors independently assessed the included studies for risk of bias. Results: Thirteen randomized controlled trials out of 158 studies identified met the inclusion criteria, with a total of 1253 participants. Twelve studies were conducted in the postoperative anesthesia care unit and two studies were performed in the emergency department setting. Four studies were double blinded, one was single blind, and eight were open label. Three studies assessed the use of inhaled IPA for prevention, whereas 10 studies evaluated its use in the treatment of nausea and vomiting. Seven studies reported IPA to be more effective, four studies reported no difference, and two studies reported IPA to be ineffective. Participant satisfaction was high overall, regardless of intervention received. No adverse effects were reported. The overall quality of evidence was low. Conclusion: There is a lack of strong evidence to support the use of inhaled IPA in the management of nausea and vomiting. Additional trials are warranted to confirm this finding and to further explore the use of inhaled IPA in various populations and settings.

Adverse events of immune checkpoint therapy alone versus when combined with vascular endothelial growth factor inhibitors: a pooled meta-analysis of 1735 patients.

Background: Combining immune checkpoint therapy (ICT) and vascular endothelial growth factor inhibitors (VEGFi) may result in increased treatment-related and immune-related adverse events (TRAEs and irAEs) compared to ICT alone. This metanalysis was conducted to identify prospective phase II or III clinical studies that evaluated the toxicity profile of ICT + VEGFi compared to ICT alone. Methods: A systematic search was performed across all cancer types and major databases until August 10, 2022, and screening was done by two independent investigators. Inclusion criteria included phase 2 or 3 studies with at least one arm of patients treated with combination therapy and one arm treated with monotherapy. Adverse event data were pooled using a restricted maximum likelihood fixed effects model, and heterogeneity using Cochran's Q (chi-square) test. Results: 7 out of 9366 studies met the inclusion criteria, and 808 and 927 patients were treated with ICT monotherapy and a combination of ICT with VEGFi, respectively. Only one study reported irAEs, so the analysis was restricted to TRAEs. The total number of TRAEs was significantly higher in the ICT + VEGFi group (RR:1.49; 95% CI 1.37 -1.62; p=1.5×10-21), and more frequent treatment withdrawals were attributed to TRAEs (RR:3.10; 95% CI 1.12-8.59; p=0.029). The highest TRAE effect size increases noted for rash (RR 6.50; 95% CI 3.76 - 11.25; p=2.1×10-11), hypertension (RR:6.07; 95% CI 3.69-10.00; p=1.3×10-12), hypothyroidism (RR:5.02; 95% CI 3.08 - 8.19; p=8.9×10-11), and diarrhea (RR:4.94; 95% CI 3.21-7.62; p=3.8×10-13). Other significantly more frequent TRAEs included nausea, anemia, anorexia, and proteinuria. Conclusion: Combination therapy with ICT and VEGFi carries a higher risk of certain TRAEs, such as rash, hypertension, hypothyroidism, diarrhea, nausea, anorexia, and proteinuria, compared to ICT monotherapy. More granular details on the cause of AEs, particularly irAEs, should be provided in future trials of such regimens.

Quality and content evaluation of websites with information about immune checkpoint inhibitors: An environmental scan.

BACKGROUND: Trustworthy educational information for patients is critical for increasing their knowledge base and preparing them for shared decision making with clinicians. As the internet has become an important source of health information for many patients, the purpose of this study was to assess the quality and content of websites with educational content about immune checkpoint inhibitors. METHODS: We performed an environmental scan of the currently available websites providing educational information for patients about immune checkpoint inhibitors. We used three search engines: Google, Bing, and Yahoo! (9/20/2021). Two independent investigators selected relevant uniform resource locators (URLs), appraised the quality of the websites, and collected their characteristics. We evaluated the accuracy, completeness, technical elements, design and aesthetics, readability, usability, and accessibility of the websites. The user experience was also evaluated. RESULTS: We identified 37 websites for analysis. In 10 websites (27%), it was not possible to know the source of the information provided. Thirty-three (89%) provided a definition with a simple explanation of cancer and treatment and 30 (81%) on complications of immune checkpoint inhibitors; only seven (19%) provided information about the balance between risks and benefits. Thirty-five (95%) provided a statement of purpose. Regarding the design, all 37 (100%) had appropriate visual aspects, typography, and grammar. Thirty-six (97%) were well organized. For most of the websites (n = 35, 95%) the content was easy to find. Only two websites had a readability score of 6, while the others had higher scores. Regarding the user experience, the overall quality of websites was rated as excellent in 16 (43%), good in 14 (38%), and fair in 7 (19%). CONCLUSIONS: Our findings reveal that websites with information about immune checkpoint inhibitors mostly have general information about cancer, the treatments, and adverse events. Few websites provide information about the balance between harms and benefits of treatment, costs, the source of the information, or the hierarchy of evidence. These findings identify the gap in the quality and content of websites for patients treated with immune checkpoint inhibitors and can help website creators and developers.
