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 infection and its consequences among surgical oncology patients: A systematic analysis, meta-analysis and meta-regression.

We conducted this meta-analysis to address the outcomes in cancer patients after oncologic surgery during COVID-19 pandemic. The primary endpoint was the COVID-19-related mortality rate. Higher body mass index was significantly and negatively associated with higher all-cause mortality and in-hospital COVID-19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all-cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID-19 infection rate.

Inclusion of Patient-Reported Outcomes in Adolescent and Young Adult Phase III Therapeutic Trials: An Analysis of Cancer Clinical Trials Registered on ClinicalTrials.gov.

OBJECTIVES: There is a paucity of research on the impact of cancer treatment on the health-related quality of life (HRQOL) of adolescent and young adult (AYA) patients with cancer. Patient-reported outcomes (PROs) are self-report measures used to assess HRQOL and symptom burden. The extent to which PROs have been included in trials that include common AYA cancer types has not been previously assessed. METHODS: Therapeutic phase 3 trials among common AYA cancer types (Hodgkin lymphoma, non-Hodgkin lymphoma, acute lymphoblastic leukemia, sarcomas, and germ cell tumors) initiated between 2007 and 2020 were identified on ClinicalTrials.gov. The proportions and characteristics of trials including a PRO endpoint were assessed. For comparison with an older population, the proportion of breast and colorectal therapeutic phase 3 trials including PRO endpoints were assessed. RESULTS: Eighty-seven studies met the inclusion criteria. Overall, 20.7% of therapeutic phase 3 AYA trials included a PRO endpoint, and only one trial published PRO data. Germ cell tumors (42.9%) and non-Hodgkin lymphoma (40%) trials had the highest proportions of PRO inclusion. The European Organization for Research and Treatment of Cancer generic, cancer-specific quality of life questionnaire was the most commonly used PRO measure; nevertheless, the measures used varied within and between cancer types. The proportion of trials including a PRO endpoint did not change significantly between 2007 to 2013 and 2014 to 2020 (18.6% vs 22.7%, P=.79). CONCLUSIONS: Few therapeutic phase 3 AYA cancer trials include PRO endpoints, fewer publish PRO data, and there is no homogeneity in the measures administered. Therapeutic trials represent an underused opportunity to capture PRO data in the AYA population with the goal of improving HRQOL outcomes.

Acupuncture for Cancer-Related Anorexia: a Review of the Current Evidence.

PURPOSE OF REVIEW: Loss of appetite/anorexia is extremely common among cancer patients, affecting as many as half of newly diagnosed patients and 70% of patients with advanced disease. Effective management of this disabling symptom of cancer remains a major challenge in the field of oncology. We conducted a systematic review of the current evidence on acupuncture and/or moxibustion as an intervention for cancer-related anorexia. RECENT FINDINGS: Acupuncture, as a part of traditional Chinese medicine practice, has demonstrated effectiveness in managing many cancer- and treatment-related symptoms, especially chemotherapy-induced or postoperative nausea. However, the efficacy of acupuncture in treating cancer-related anorexia/loss of appetite is not clear. The current level of evidence is insufficient to make a definitive conclusion on the benefit of acupuncture/moxibustion for treating chronic cancer-related anorexia/appetite problems. Future large randomized controlled trials of high methodological quality are needed.

Prevalence of medication related osteonecrosis of the jaw in patients treated with sequential antiresorptive drugs: systematic review and meta-analysis.

BACKGROUND: Antiresorptive drugs (ARD) are associated with a known serious adverse event, known as medication-related osteonecrosis of the jaws (MRONJ). Transition from one ARD to another has become common clinical practice with the advent of more potent or safer agents; however, the influence of sequential antiresorptive therapy as a risk factor for MRONJ has not been established. OBJECTIVES: To investigate the prevalence of MRONJ in oncology or osteoporosis patients treated with two or more sequential ARDs as opposed to a single antiresorptive drug. MATERIAL AND METHODS: Systematic electronic literature searches were conducted using Ovid MEDLINE, Ovid EMBASE, and Cochrane Central Register of Controlled Trials. Two review authors retrieved studies using pre-determined eligibility criteria and conducted quality assessment and data extraction. Fixed or random-effects meta-analysis models were used to summarize relative estimates for prevalence of MRONJ. RESULTS: A total of 483 titles and abstracts were screened, and 18 full texts were retrieved for review. Twelve studies were included in the final qualitative and quantitative synthesis. Random effects meta-analysis models revealed a weighted pooled MRONJ prevalence of 19% (95% CI 10-27%) for sequential pamidronate-zoledronate therapy, 10% (95% CI 3-22%) for sequential ibandronate-zoledronate therapy. Pooled weighted prevalence of MRONJ was 13% (95% CI 3-22%) for sequential bisphosphonate-denosumab therapy while bisphosphonates only was 5% (95% CI 0-9%) and denosumab only was 4% (95% CI 3-5%). CONCLUSIONS: The present systematic review suggests an increased prevalence of MRONJ associated with sequential ARD therapy for pamidronate-zoledronate and bisphosphonate-denosumab administration when compared to single ARD therapy.

A systematic review of behavioral interventions for rural breast cancer survivors.

Rural breast cancer survivors (RBCS) are at greater risk for poorer health outcomes and face greater treatment barriers compared to their urban counterparts, necessitating behavioral interventions tailored for the unique needs of RBCS. A systematic review of studies examining behavioral interventions delivered to RBCS living in the United States from 2000 to 2020 was conducted following PRIMSA guidelines. Nineteen unique studies were included: eight randomized controlled trials, two matched-control studies, six pre-post intervention feasibility studies, and three post-intervention satisfaction studies. Thirteen interventions aimed to improve psychosocial support, three to improve weight management, and three to improve education. Results indicate interventions' feasibility and acceptability. Six out of eight intervention conditions reported favorable outcomes compared to control conditions, suggesting promise for efficacy. However, variability in intervention objective, duration, delivery, and follow-up timing, and small sample sizes prevent overarching conclusions. Research involving larger sample sizes, higher quality control groups, and longer follow-up data is needed.

The effects of zinc on radiation-induced dysgeusia: a systematic review and meta-analysis.

PURPOSE: Many head and neck cancer patients who receive radiation therapy experience radiation-induced dysgeusia (RID), which has no standard treatment. The only supplement controlled clinical trials have evaluated for the treatment of RID is zinc. However, the results of these and other studies investigating the use of zinc for RID have been inconsistent. To assess the validity of zinc as a treatment for RID, we conducted a systematic literature search and performed a meta-analysis to determine the extent to which zinc affects RID incidence and the degree to which ongoing RID responds to zinc. METHODS: We searched the Ovid MEDLINE, Ovid Embase, PubMed, and Cochrane Library databases to identify studies investigating the use of zinc-based therapy for RID in head and neck cancer patients treated with radiation that were published between January 1, 2003, and November 9, 2017. Using American Society of Clinical Oncology criteria, we selected studies with a high level of evidence for inclusion in the meta-analysis. RESULTS: Of the 32 full-text articles eligible for inclusion, three were included in the final review and meta-analysis. The meta-analysis showed that, compared with placebo, zinc reduces the incidence of RID (risk ratio, 0.72; 95% confidence interval, 0.67-0.92) but does not improve taste acuity more rapidly following radiation therapy (risk ratio, 2.58; 95% confidence interval, 0.97-6.88). CONCLUSION: Our findings indicate that zinc-based therapy reduces the incidence of RID but has a minimal effect on ongoing RID. Our findings also highlight the need for additional evidence-based research on this topic.

The sug operon involves in resistance to quaternary ammonium compounds in Listeria monocytogenes EGD-e.

In recent years, an increasing number of Listeria monocytogenes strains with resistance to quaternary ammonium compounds (QACs) have been reported. However, the genetic basis for QACs resistance in L. monocytogenes remains poorly understood. In the present study, we have characterized the operon lmo0852/lmo0853/lmo0854 (designated sugR/sugE1/sugE2) that contributes to QACs' resistance in L. monocytogenes EGD-e. We constructed the gene deletion mutants and the complemented strains, determined minimum inhibitory concentrations (MICs) of these strains against antimicrobial agents, assessed the transcription levels of target genes by RT-qPCR, and measured the promoter activity by using ß-galactosidase assays. We also investigated the interaction between the promoter DNA and the putative regulatory protein by electrophoretic mobility shift assay (EMSA). The sug operon consists of a putative TetR family regulator encoded by sugR and two small multidrug resistance (SMR) efflux pumps encoded by sugE1 and sugE2. Our results showed that either SugE1 or SugE2 is sufficient for QACs' resistance, indicating their function overlapping in QACs' resistance. Interestingly, lacking one sugE gene could lead to a significant increase in transcription of the other sugE gene in the presence of benzalkonium chloride (BC). Additionally, SugR negatively regulates the transcription of the sug locus by binding to the operon promoter. Given that QACs are commonly used in food industry, the findings from this study will help us to have a better understanding of the adaptations of L. monocytogenes to this type of disinfectant. Key points •Either SugE1 or SugE2 was sufficient for QACs resistance. •The functions of two sug genes overlap and compensate each other in QACs resistance. •SugR is the transcriptional suppressor of sugE1 and sugE2. •SugR regulates the sug locus by binding to the operon promoter.

The VirAB-VirSR-AnrAB Multicomponent System Is Involved in Resistance of Listeria monocytogenes EGD-e to Cephalosporins, Bacitracin, Nisin, Benzalkonium Chloride, and Ethidium Bromide.

In Listeria monocytogenes, it has been proposed that the VirSR two-component signal transduction systems (TCSs) and two ATP-binding cassette (ABC) transporters, VirAB and AnrAB, constitute a complex TCS/ABC transporter system which has been recognized as a unique resistance mode. The role of the putative VirAB-VirSR-AnrAB system in antimicrobial resistance and the respective contributions of the members of the system to resistance were investigated in this study. We constructed gene deletion mutants of L. monocytogenes EGD-e and complemented strains of the mutants and determined MICs of antimicrobial agents against these strains against using the agar dilution method. We assessed the relative expression levels of target genes by reverse transcription-quantitative PCR (RT-qPCR) and measured promoter activity levels by ß-galactosidase assays. Our results showed that the VirAB-VirSR-AnrAB system mediates not only nisin and bacitracin resistance but also resistance to cephalosporins, ethidium bromide (EtBr), and benzalkonium chloride (BC). In this system, two ABC transporters, VirAB and AnrAB, play distinct roles in cefotaxime resistance: the former is responsible only for antimicrobial sensing and signaling by VirSR, while the latter contributes to transportation of antimicrobials. Notably, VirAB itself, rather than the VirAB-VirSR-AnrAB system as a whole, contributes to kanamycin and tetracycline resistance. On the basis of the results obtained from this study, we speculate that VirAB acts as a sensor for VirSR in response to cephalosporins, bacitracin, nisin, EtBr, and BC, while VirAB itself plays a role in response to kanamycin and tetracycline in L. monocytogenes EGD-e.IMPORTANCE This report describes TCS/ABC transporter modules characterized in Listeria monocytogenes EGD-e. The modules consist of the VirSR TCS and the VirAB and AnrAB ABC transporters. Our results showed that this system is involved in nisin and bacitracin resistance, as well as resistance to cephalosporins, ethidium bromide (EtBr), and benzalkonium chloride (BC). In this system, VirAB is responsible only for antimicrobial sensing and signaling by VirSR, while AnrAB contributes to transportation of antimicrobials. Interestingly, VirAB itself, rather than the VirAB-VirSR-AnrAB system as a whole, contributes to kanamycin and tetracycline resistance.

EUS-guided fiducial placement for GI malignancies: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Image-guided radiotherapy (IGRT) allows the delivery of radiation with high precision to a target lesion while minimizing toxicity to surrounding tissues. EUS provides excellent visualization of GI tumors and consequently is being used for fiducial placement with increased frequency. Our goal was to perform a systematic review and meta-analysis of studies evaluating the technical aspects, safety, and efficacy of EUS fiducial placement for IGRT in GI malignancies. METHODS: A systematic literature search was carried out in the following databases: Medline, PubMed, Embase, Web of Science, and Cochrane Library, using Medical Subject Headings terms combined with text words. A random effects model was used to determine pooled proportions of technical success, migration, and adverse event rates. Heterogeneity was assessed using the I2 statistic. Publication bias was assessed visually using a funnel plot and by the Begg and Egger tests. RESULTS: Nine full articles and 5 abstracts reporting on 1155 patients, 49% from a single study by Dhadham et al, were included in the meta-analysis. The pooled rate of technical success was 98% (95% confidence interval [CI], 96-99). Moderate heterogeneity (I2 = 34.18) was present, which appeared to be due to variable sample sizes. Publication bias was present, suggesting that studies with less-substantial outcomes may have not been reported (Begg test, P = .87; Egger test, P < .01). Pooled rates for fiducial migration and adverse events were 3% (95% CI, 1.0-8.0) and 4% (95% CI, 3-7), respectively. CONCLUSIONS: Our meta-analysis showed that EUS-guided insertion of gold fiducials for IGRT is technically feasible and safe. Further controlled studies assessing its long-term effectiveness in GI malignancies are needed.

Financial Burdens of Cancer Treatment: A Systematic Review of Risk Factors and Outcomes.

BACKGROUND: Patients with cancer experience financial toxicity from the costs of treatment, as well as material and psychologic stress related to this burden. A synthesized understanding of predictors and outcomes of the financial burdens associated with cancer care is needed to underpin strategic responses in oncology care. This study systematically reviewed risk factors and outcomes associated with financial burdens related to cancer treatment. METHODS: MEDLINE, Embase, PubMed, PsychINFO, and the Cochrane Library were searched from study inception through June 2018, and reference lists were scanned from studies of patient-level predictors and outcomes of financial burdens in US patients with cancer (aged ≥18 years). Two reviewers conducted screening, abstraction, and quality assessment. Variables associated with financial burdens were synthesized. When possible, pooled estimates of associations were calculated using random-effects models. RESULTS: A total of 74 observational studies of financial burdens in 598,751 patients with cancer were identified, among which 49% of patients reported material or psychologic financial burdens (95% CI, 41%-56%). Socioeconomic predictors of worse financial burdens with treatment were lack of health insurance, lower income, unemployment, and younger age at cancer diagnosis. Compared with patients with health insurance, those who were uninsured demonstrated twice the odds of financial burdens (pooled odds ratio [OR], 2.09; 95% CI, 1.33-3.30). Financial burdens were most severe early in cancer treatment, did not differ by disease site, and were associated with worse health-related quality of life (HRQoL) and nearly twice the odds of cancer medication nonadherence (pooled OR, 1.70; 95% CI, 1.13-2.56). Only a single study demonstrated an association with increased mortality. Studies assessing the comparative effectiveness of interventions to mitigate financial burdens in patients with cancer were lacking. CONCLUSIONS: Evidence showed that financial burdens are common, disproportionately impacting younger and socioeconomically disadvantaged patients with cancer, across disease sites, and are associated with worse treatment adherence and HRQoL. Available evidence helped identify vulnerable patients needing oncology provider engagement and response, but evidence is critically needed on the effectiveness of interventions designed to mitigate financial burden and impact.

Referral Criteria for Outpatient Palliative Cancer Care: A Systematic Review.

BACKGROUND: Outpatient palliative care clinics facilitate early referral and are associated with improved outcomes in cancer patients. However, appropriate candidates for outpatient palliative care referral and optimal timing remain unclear. We conducted a systematic review of the literature to identify criteria that are considered when an outpatient palliative cancer care referral is initiated. METHODS: We searched Ovid MEDLINE (1948-2013 citations) and Ovid Embase (1947-2015 citations) for articles related to outpatient palliative cancer care. Two researchers independently reviewed each citation for inclusion and extracted the referral criteria. The interrater agreement was high (κ = 0.96). RESULTS: Of the 186 publications in our initial search, 21 were included in the final sample. We identified 20 unique referral criteria. Among these, 6 were recurrent themes, which included physical symptoms (n = 13 [62%]), cancer trajectory (n = 13 [62%]), prognosis (n = 7 [33%]), performance status (n = 7 [33%]), psychosocial distress (n = 6 [29%]), and end-of-life care planning (n = 5 [24%]). We found significant variations among the articles regarding the definition of advanced cancer and the assessment tools for symptom/distress screening. The Edmonton Symptom Assessment Scale (n = 7 [33%]) and the distress thermometer (n = 2 [10%]) were used most often. Furthermore, there was a lack of consensus in the cutoffs in symptom assessment tools and timing for outpatient palliative care referral. CONCLUSION: This systematic review identified 20 criteria including 6 recurrent themes for outpatient cancer palliative care referral. It highlights the significant heterogeneity regarding the timing and process for referral and the need for further research to develop standardized referral criteria. IMPLICATIONS FOR PRACTICE: Outpatient palliative care clinics improve patient outcomes; however, it remains unclear who is appropriate for referral and what is the optimal timing. A better understanding of the referral criteria would help (a) referring clinicians to identify appropriate patients for palliative care interventions, (b) administrators to assess their programs with set benchmarks for quality improvement, (c) researchers to standardize inclusion criteria, and (d) policymakers to develop clinical care pathways and allocate appropriate resources. This systematic review identified 20 criteria including 6 recurrent themes for outpatient palliative cancer care referral. It represents the first step toward developing standardized referral criteria.

Current use of drugs affecting the central nervous system for chemotherapy-induced peripheral neuropathy in cancer patients: a systematic review.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is common among cancer patients who undergo chemotherapy with platinum analogues, taxanes, vinca alkaloids, epothilone, bortezomib, and thalidomide. The purpose of this study was to investigate the evidence of using drugs affecting the central nervous system (CNS) to alleviate CIPN in cancer patients. METHODS: A systematic literature search was conducted using the CINAHL, EMBASE, and Medline databases to identify randomized controlled clinical trials (RCTs) reported in English up to 2013. We identified ten trials of CNS-acting drugs used to treat CIPN in cancer patients and reviewed efficacy and safety of CNS-acting drugs for CIPN using a standard data collection form. The risk of bias in each RCT was also assessed. RESULTS: Antidepressants were used in six studies and anticonvulsants in four studies. We found positive results for amitriptyline (topical), venlafaxine, and oxcarbazepine in one study each, but the results were not sufficient to draw definite conclusions. One trial with duloxetine showed a moderate effect (effect size, 0.513, P = .003) on CIPN pain relief. However, none of the results has yet been duplicated in an RCT with a large sample size. CONCLUSIONS: Insufficient RCTs exist to confirm the efficacy of CNS agents to reduce CIPN. This study highlighted the need for and the importance of conducting well-designed RCTs to generate evidence on CIPN symptom management. Additional RCTs are warranted to accelerate the potential use of CNS drugs for CIPN in cancer patients.

Clinical librarian support for rapid review of clinical utility of cancer molecular biomarkers.

The clinical librarian used a restricted literature searching and quality-filtering approach to provide relevant clinical evidence for the use of cancer molecular biomarkers by institutional policy makers and clinicians in the rapid review process. The librarian-provided evidence was compared with the cited references in the institutional molecular biomarker algorithm. The overall incorporation rate of the librarian-provided references into the algorithm was above 80%. This study suggests the usefulness of clinical librarian expertise for clinical practice. The searching and filtering methods for high-level evidence can be adopted by information professionals who are involved in the rapid literature review.

METHODS: By groping the management experience of IVD reagents, we discuss the internal hospital management mode of IVD reagents in reality. RESULTS: With the continuous improvements on the information platform of IVD reagents,we can realize benefit analysis of IVD reagents within the process of management. CONCLUSION: Reasonable management on IVD reagentscan improve the working efficiency in hospitals and provide swifter and better medical service for patients.

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.

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.

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.

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.

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.
