Systematic review and meta-analysis of adjuvant radiation dose for pediatric patients (≤22y) with non-metastatic intracranial ependymomas.

BACKGROUND/PURPOSE: Ependymomas are the third most common brain tumors in children. Standard of care is surgery followed by adjuvant radiotherapy. Controversy in the literature still exists over optimal radiotherapy dose. We completed a systematic review and meta-analysis to determine the optimal dose for local control (LC), event-free survival (EFS), and overall survival (OS) in pediatric patients. MATERIALS & METHODS: We searched MEDLINE (PubMed), Cochrane Database of Systematic Reviews, and Web of Science through January 2024. We included cohort studies that compared adjuvant radiotherapy of ≤54Gy to >54Gy in pediatric patients (≤22 years) with non-metastatic intracranial ependymomas. We assessed study quality using the Newcastle-Ottawa Quality Assessment Scale of Cohort Studies. We pooled studies using a random effects meta-analysis for hazard ratios (HR), 95% confidence intervals (CI), and assessed statistical heterogeneity via I2. When HRs were unavailable, we transformed risks using established methods. We narratively summarized qualitative outcomes. RESULTS: Seven studies met our inclusion criteria, covering a combined 1321 patients. Studies included a range of doses from 45-66.6Gy. Compared with >54Gy, we found no difference in LC for those receiving ≤54Gy (HR=0.83, 95% CI 0.56-1.24, I2=49.1%), in EFS (HR=1.02, 95% CI 0.95-1.09, I2=0.00%), and OS (HR=0.99, 95% CI 0.82-1.20, I2=37.5%). Two studies reported on subtotal resection by radiotherapy dose, neither study reporting statistical differences in LC, EFS, or OS, though the number of patients was small (n≤30). Five studies reported on late effects, with brainstem radionecrosis, radiation-induced vasculopathy, and secondary tumors being the most frequent. Overall study quality was high, though lower scores were consistently seen in comparability of cohorts. No studies reported on molecular subgroups. CONCLUSIONS: We found no difference in LC, EFS, or OS for those treated with ≤54Gy compared to >54Gy. There was insufficient data to complete a subgroup meta-analysis on radiotherapy dosing based on extent of resection or molecular subgroups.

The impact of limited English proficiency on oncological outcomes in the United States: A systematic review.

BACKGROUND: The increasing number of immigrants in the United States (U.S.) has resulted in more patients with limited English proficiency (LEP). LEP contributes to patient-provider language discordance, which may impact oncologic health outcomes. OBJECTIVES: To assess the effects of LEP compared to English proficiency (EP) for oncological outcomes in adult cancer patients in the United States. SEARCH METHODS: We searched MEDLINE (Ovid), the Cochrane Library (Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials), PsycINFO, CINAHL and Scopus from data inception to 26 January 2023. We also searched the reference lists and cited lists of included studies. Studies were limited to the United States and the English language. SELECTION CRITERIA: We included retrospective and cross-sectional studies that analyzed one or more clinical outcomes (survival, readmission, length of stay, complications and discharge disposition) in LEP and EP cancer patients. Studies were eligible if they assessed cancer patients in the United States who were 18 years and older. DATA COLLECTION AND ANALYSIS: Using a piloted, standardized data collection form, two non-blinded, independent reviewers extracted data in duplicate from studies meeting our inclusion criteria. Reviewers resolved discrepancies through discussion. We then performed a qualitative assessment of the findings. MAIN RESULTS: We retrieved 2425 records from the database searches. We screened 1496 records by title and abstract and reviewed the full text of eight records. We retrieved 347 records from additional search methods and reviewed the full text of six records. We included 14 papers in total for analysis. The studies included 55,141 total patients and assessed outcomes in brain, oesophageal, head and neck, pancreatic and skin cancer. Our qualitative assessment demonstrated limited information on whether LEP impacted survival, complications and discharge disposition. We found no significant association between LEP and readmission or length of stay. CONCLUSIONS: Studies assessing the impact of LEP and EP on the health outcomes of cancer patients are sparse and inconsistent in the measurements of outcomes and data reporting. The inconclusiveness of our study indicates that further standardized research is needed to assess the impact of LEP on the outcomes of cancer patients in the United States.

A Systematic Review and Meta-analysis of the Role of Preoperative MRI in In-breast Tumor Recurrence After Breast-Conserving Surgery.

BACKGROUND: It is unknown whether the identification of additional tumors in the breast using preoperative magnetic resonance imaging (pMRI) results in a lower risk of in-breast tumor recurrence (IBTR) after breast-conserving surgery (BCS). METHODS: A systematic review and meta-analysis of relevant studies were performed. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: From 768 citations, 20 studies met the inclusion criteria for the systematic review. The 20 studies consisted of 14 retrospective reviews, 3 matched cohorts, and 3 randomized controlled trials. Whereas 2 studies reported a statistically significant lower rate of IBTR with pMRI, 18 studies showed no difference, and no studies reported a higher rate. Of the 18 studies showing no significant difference, 12 demonstrated a trend toward a lower IBTR rate in the pMRI group. The criteria for meta-analysis were met by 16 studies. A meta-analysis of 11 studies that reported hazard ratios (HR) for IBTR showed a trend toward a lower rate of IBTR for patients who received preoperative MRI (hazard ratio (HR), 0.89; 95% confidence interval (CI), 0.74-1.05). A meta-analysis of five studies that reported event rates and had similar follow-up duration for both groups demonstrated a lower relative risk (RR) of IBTR (RR, 0.45; 95% CI 0.25-0.81). CONCLUSIONS: Although some evidence supports the hypothesis that identification of additional tumors in the breast using pMRI results in lower rates of IBTR after BCS, the main meta-analysis in this study did not confirm this hypothesis.

Clinician-Spoken Plain Language in Health Care Encounters: A Qualitative Analysis to Assess Measurable Elements.

PURPOSE: Good communication and use of plain language in health care encounters improve outcomes, including emotional health, symptom resolution, and functional status. Yet there is limited research on how to measure and report spoken plain language, which is the use of familiar, clear language. The authors aimed to describe key, measurable elements of spoken plain language that can be assessed and reported back to clinicians for self-reflection. METHOD: The authors conducted secondary analysis of transcripts from recorded encounters between breast cancer surgeons and patients with early-stage breast cancer. Two coders used a hybrid qualitative analysis with a framework based on U.S. Federal Plain Language Guidelines. To develop major themes, they examined (1) alignment with the Guidelines and (2) code frequencies within and across transcripts. They also noted minor themes. RESULTS: From 74 transcripts featuring 13 surgeons, the authors identified 2 major themes representing measurable elements of spoken plain language: (1) clinicians had a propensity to use both explained and unexplained medical terms, and (2) clinicians delivered information using either short turns (one unit of someone speaking) with 1 topic or long turns with multiple topics. There were 3 minor themes that were not indicative of whether or not clinicians used spoken plain language. First, clinicians regularly used absolute risk communication techniques. Second, question-asking techniques varied and included open-ended, close-ended, and comprehension checks. Third, some clinicians used imagery to describe complex topics. CONCLUSIONS: Clinicians' propensity to use medical terms with and without explanation and parse encounters into shorter or longer turns are measurable elements of spoken plain language. These findings will support further research on the development of a tool that can be used in medical education and other settings. This tool could provide direct and specific feedback to improve the plain language practices of clinicians in training and beyond.

Examining interventions that aim to enhance TB treatment adherence in Southeast Asia: A systematic review and meta-analysis.

BACKGROUND: Adherence is often a barrier to curative treatment of Mycobacterium tuberculosis (TB). There have been numerous interventions focused on increasing TB treatment adherence in Southeast Asia, but it is unclear if they are effective. This systematic review and meta-analysis aimed to compile and evaluate the literature on interventions designed to increase TB treatment adherence in Southeast Asia. METHODS: We searched Cochrane Library Reviews (CDSR) and Cochrane Library Trials (CENTRAL), Medline, CINAHL, Scopus, and Web of Science from 2000 to 2022 with no language restrictions. We included studies of any design conducted in Southeast Asia that implemented interventions to increase treatment completion in people diagnosed with TB and assessed completion as an outcome. We did not require a control group. Four investigators used a standardized data collection form to collate results. The heterogeneity across studies was explored by I2 statistics. We assessed bias using the Newcastle-Ottawa Scale and Cochrane ROB 2.0. We used a random effects meta-analysis to calculate a pooled risk ratio with 95% confidence intervals. RESULTS: From 1881 abstracts, we included 14 articles. There were 7198 subjects with 3163 (44%) receiving a TB treatment adherence intervention across eight countries. Interventions included directly observed therapy, text-message reminders, food incentives, and more. The risk ratio, derived from the meta-analysis of eight included studies with a control group and 6618 participants overall, was 1.04 (95% CI 1.01,1.08; I2 = 29%), favoring the interventions over controls with little concern for heterogeneity or risk of bias. When narratively assessed, the other six studies all reported increased adherence in the intervention group. DISCUSSION: The results suggested there is a small, statistically significant benefit of using interventions to promote TB treatment completion. Future research could look at additional strategies and combinations of strategies to promote adherence.
