The success of chimeric antigen receptor (CAR) T-cell therapy in treating patients with relapsed/refractory hematologic malignancies is leading to a growing number of survivors treated with this regimen. To date, no studies to our knowledge have examined neurocognitive performance in adult CAR T-cell therapy recipients, despite high rates of neurotoxicity and cytokine release syndrome (CRS) in the acute treatment period. This study examined changes in neurocognitive performance in the first year after CAR-T-cell therapy for non-Hodgkin’s lymphoma (NHL). Putative risk factors for worsening neurocognitive performance (e.g., neurotoxicity, CRS) were also explored. Neurocognition was assessed at prior to CAR T-cell therapy and at days 30, 90, and 360. Clinical variables were abstracted from medical records. Mixed models were used to examine change in total neurocognitive performance (TNP) and cognitive domains (i.e., attention, executive function, verbal ability, immediate and delayed memory, visuospatial abilities). Among 117 participants (mean age 61, 62% male), TNP and executive function declined slightly on average from baseline to day 90, then improved from day 90 to 360 (p values <0.04). Small but significant linear declines over time, on average, in visuospatial abilities were also observed (p=0.03). Patients who had four or more lines of previous therapy, and those with worse neurotoxicity (but not CRS), demonstrated worse TNP. CAR T-cell therapy recipients reported transient or persistent deterioration in several cognitive domains, although changes were small. These findings may be useful when educating future patients on what to expect when receiving CAR T-cell therapy.

Background: The use of web-based methods to collect population-based health behavior data has burgeoned over the past two decades. Researchers have used web-based platforms and research panels to study a myriad of topics. Data cleaning prior to statistical analysis of web-based survey data is an important step for data integrity. However, the data cleaning processes used by research teams are often not reported. Objective: The objectives of this manuscript are to describe the use of a systematic approach to clean the data collected via a web-based platform from panelists and to share lessons learned with other research teams to promote high-quality data cleaning process improvements. Methods: Data for this web-based survey study were collected from a research panel that is available for scientific and marketing research. Participants (N=4000) were panelists recruited either directly or through verified partners of the research panel, were aged 18 to 45 years, were living in the United States, had proficiency in the English language, and had access to the internet. Eligible participants completed a health behavior survey via Qualtrics. Informed by recommendations from the literature, our interdisciplinary research team developed and implemented a systematic and sequential plan to inform data cleaning processes. This included the following: (1) reviewing survey completion speed, (2) identifying consecutive responses, (3) identifying cases with contradictory responses, and (4) assessing the quality of open-ended responses. Implementation of these strategies is described in detail, and the Checklist for E-Survey Data Integrity is offered as a tool for other investigators. Results: Data cleaning procedures resulted in the removal of 1278 out of 4000 (31.95%) response records, which failed one or more data quality checks. First, approximately one-sixth of records (n=648, 16.20%) were removed because respondents completed the survey unrealistically quickly (ie, <10 minutes). Next, 7.30% (n=292) of records were removed because they contained evidence of consecutive responses. A total of 4.68% (n=187) of records were subsequently removed due to instances of conflicting responses. Finally, a total of 3.78% (n=151) of records were removed due to poor-quality open-ended responses. Thus, after these data cleaning steps, the final sample contained 2722 responses, representing 68.05% of the original sample. Conclusions: Examining data integrity and promoting transparency of data cleaning reporting is imperative for web-based survey research. Ensuring a high quality of data both prior to and following data collection is important. Our systematic approach helped eliminate records flagged as being of questionable quality. Data cleaning and management procedures should be reported more frequently, and systematic approaches should be adopted as standards of good practice in this type of research.

Background: Cultural background, language, and literacy are factors that may affect access, healthcare utilization, and cancer screening behaviors. Objective: This study aimed to characterize health literacy among Spanish-preferring Hispanic/Latino individuals ages 50–75 and examine associations between sociodemographic characteristics, health beliefs, and health literacy. Methods: Participants self-identified as Hispanic/Latino, preferring health information in Spanish, were ages 50–75 years old, at average risk for colorectal cancer (CRC), not up to date with CRC screening, and enrolled in a CRC screening education intervention trial. Sociodemographic characteristics, health beliefs, and health literacy (i.e., difficulty understanding written health information and confidence completing health forms) were assessed at baseline. Descriptive and logistic regression analyses were performed. Results: Fifty-three percent of participants reported either sometimes having difficulty or always having difficulty with written health information, and 25% reported always asking for help or being not so confident in completing health forms. Univariate predictors of adequate health literacy for written health information were lower cancer worry and lower religious beliefs. Higher educational attainment predicted confidence in completing health forms. Conclusions: Findings highlight the need for interventions that address health beliefs and health literacy among Hispanic/Latino patients who have low confidence in completing written forms and difficulty understanding written information and reinforce the use of plain language and salient design features when developing patient education materials.

Trials of immune checkpoint inhibitors (ICIs) have published patient-reported quality of life (QOL), but the size and heterogeneity of this literature can make patient education difficult. This meta-analysis aimed to describe change in QOL and symptomatology in patients receiving ICIs for cancer. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases were searched through November 2019 for articles or abstracts of prospective, original studies reporting longitudinal QOL in adult cancer patients treated with ICIs. The prespecified primary outcomes were change in global QOL among patients treated with ICIs and difference in change since baseline in global QOL between patients treated with ICI vs non-ICI active treatment. Secondary outcomes included physical functioning and symptomatology. All statistical tests were 2-sided. Of 20 323 publications, 26 met inclusion criteria. Global QOL did not change over time in patients treated with ICIs (k = 26, n = 6974; P = .19). Larger improvements in global QOL was observed in patients receiving ICI vs non-ICI regimens (k = 16, ICI: n = 3588; non-ICI: n = 2948; P < .001). Physical functioning did not change in patients treated with ICIs (k = 14, n = 3169; P = .47); there were no differences in mean change between ICI vs non-ICI regimens (k = 11, n = 4630; P = .94). Regarding symptoms, appetite loss, insomnia, and pain severity decreased, but dyspnea severity increased in patients treated with ICIs (k = 14, n = 3243-3499; P < .001). Insomnia severity was higher in patients treated with ICIs than non-ICI regimens (k = 11, n = 4791; P < .001). This study is among the first to quantitatively summarize QOL in patients treated with ICIs. Findings suggest ICI recipients report no change in global QOL and higher QOL than patients treated with non-ICI regimens.
