Disparities In Cancer Care Research Articles

Bringing CAR T cell therapy trials to underserved populations

There is a critical need for equitable access to cell therapies in cancer treatment, particularly within public safety-net healthcare systems that serve minority and socioeconomically disadvantaged populations. We discuss how the Dan L Duncan Comprehensive Cancer Center at Baylor College of Medicine is piloting a cell therapy program aimed at addressing cancer care disparities and has the potential to serve as a national model for enhancing health equity in cancer care.

The South African breast cancer and HIV outcomes study: Profiling the cancer centres and cohort characteristics, diagnostic pathways, and treatment approaches.

The South African Breast Cancer and HIV Outcomes prospective cohort (SABCHO) study was established to investigate survival determinants among HIV-positive and HIV-negative SA women with breast cancer. This paper describes common and unique characteristics of the cancer centres and their participants, examining disparities in pathways to diagnosis, treatment resources and approaches adopted to mitigate resource constraints. The Johannesburg (Jhb), Soweto (Sow), and Durban (Dbn) sites treat mainly urban, relatively better educated and more socioeconomically advantaged patients whereas the Pietermaritzburg (Pmb) and Empangeni (Emp) sites treat predominantly rural, less educated and more impoverished communities The Sow, Jhb, and Emp sites had relatively younger patients (mean ages 54 ±14.5, 55±13.7 and 54±14.3 respectively), whereas patients at the Dbn and Pmb sites, with greater representation of Asian Indian women, were relatively older (mean age 57 ±13.9 and 58 ±14.6 respectively). HIV prevalence among the cohort was high, ranging from 15%-42%, (Cohort obesity (BMI ≥ 30 kg/m2) at 60%, self-reported hypertension (41%) and diabetes (13%). Direct referral of patients from primary care clinics to cancer centre occurred only at the Sow site which uniquely ran an open clinic and where early stage (I and II) proportions were highest at 48.5%. The other sites relied on indirect patient referral from regional hospitals where significant delays in diagnostics occurred and early-stage proportions were a low (15%- 37.3%). The Emp site referred patients for all treatments to the Dbn site located 200km away; the Sow site provided surgery and endocrine treatment services but referred patients to the Jhb site 30 Km away for chemo- and radiation therapy. The Jhb, Dbn and Pmb sites all provided complete oncology treatment services. All treatment centres followed international guidelines for their treatment approaches. Findings may inform policy interventions to address national and regional disparities in breast cancer care.

The impact of social determinants of health on thyroid cancer mortality and time to treatment

BackgroundWhereas racial disparities in thyroid cancer care are well established, the role of social determinants of health is less clear. We aimed to assess the individual and cumulative impact of social determinants of health on mortality and time to treatment among patients with thyroid cancer. MethodsWe collected social determinants of health data from thyroid cancer patients registered in the National Cancer Database from 2004 to 2017. We created a count variable for patients in the lowest quartile of each social determinant of health (ie, low income, low education, and no insurance). We assessed the association of social determinants of health with mortality and time to treatment and the association between cumulative social determinants of health count and time to treatment using Cox regression. ResultsOf the 142,024 patients we identified, patients with longer time to treatment had greater mortality compared to patients treated within 90 days (90–180 days, adjusted hazard ratio 1.21 (95% confidence interval 1.13–1.29, P < .001); >180 days, adjusted hazard ratio 1.57 (95% confidence interval 1.41–1.76, (P < .001). Compared to patients with no adverse social determinants of health, patients with 1, 2, or 3 adverse social determinants of health had a 10%, 12%, and 34%, respectively, higher likelihood of longer time to treatment (1 social determinant of health, hazard ratio 0.90, 95% confidence interval 0.89–0.92, P < .001; 2 social determinants of health, hazard ratio 0.88, 95% confidence interval 0.87–0.90, P < .001; 3 social determinants of health, hazard ratio 0.66, 95% confidence interval 0.62–0.71, P < .001 for all). On subgroup analysis by race, each adverse social determinant of health was associated with an increased likelihood of a longer time to treatment for Black and Hispanic patients (P < .05). ConclusionA greater number of adverse social determinants of health leads to a higher likelihood of a longer time to treatment for patients with thyroid cancer, which, in turn, is associated with an increased risk for mortality.

Black cancer patients navigating a health-care system of racial discrimination.

Exposure to racial discrimination may exacerbate disparities throughout the cancer care continuum. Therefore, we explored how experiences of racial discrimination in the health-care setting manifest for Black cancer patients and how it contributes to racial disparities in cancer care. This qualitative analysis used semistructured in-depth interviews with Black cancer survivors not on active treatment from May 2019 to March 2020. All interviews were audio recorded, professionally transcribed, and uploaded into Dedoose software for analysis. We identified major themes and subthemes that highlight exposure to racial discrimination and its consequences for Black cancer patients when receiving cancer care. Participants included 18 Black cancer survivors, aged 29-88 years. Most patients experienced racial discrimination when seeking care. Participants experienced racial discrimination from their interactions with health-care staff, medical assistants, front desk staff, and health insurance administrators. Exposure to overt racial discrimination in the health-care setting was rooted in racial stereotypes and manifested through verbal insults such as physicians using phrases such as "you people." These experiences impacted the ability of the health-care delivery system to demonstrate trustworthiness. Patients noted "walking out" of their visit and not having their health issues addressed. Despite experiences with racial discrimination, patients still sought care out of necessity believing it was an inevitable part of the Black individual experience. We identified that exposure to racial discrimination in the health-care setting is pervasive, affects health-seeking behaviors, and degrades the patient-clinician relationship, which may likely contribute to racial disparities in cancer care.

A cancer disparities curriculum in a hematology/oncology fellowship program

BackgroundAfter George Floyd’s murder in 2020, the Center for Disease Control and Prevention (CDC) called systemic racism a public health crisis. This health crisis is connected to the already-documented racial and socioeconomic disparities in cancer care. Ensuring hematologists and oncologists are aware of these disparities through their medical education can help to address these disparities.MethodsThe authors implemented a healthcare disparities-focused curriculum in a Hematology/Oncology fellowship program during the 2020–2021 academic year at The Ohio State University Hematology/Oncology Fellowship Program. They implemented a pre- and post- survey to evaluate the efficacy of the program.ResultsFifteen fellows completed the pre-curriculum survey and 14 completed the post-survey. Before the curriculum, 12 fellows (80%) noted a “Fair” or “Good” understanding of healthcare disparities, and 6 (40%) had a “Fair” understanding of disparities in clinical trials and access to novel therapies. Fourteen fellows (93.3%) had not previously participated in a research project focused on identifying or overcoming healthcare disparities. After the curriculum, 12 (85%) fellows strongly agreed or agreed that the information presented in the curriculum was useful for training as a hematologist/oncologist. Twelve fellows (85%) noted “Agree” or “Strongly Agree” that the information presented was relevant to their practice. Eleven fellows (92%) noted that they plan to incorporate healthcare disparities into a future research or clinical project. The majority of fellows, 11 (79%) recommended that the fellowship program continue to have a formal health disparities curriculum in the future.Discussion/ConclusionThere is utility in incorporating cancer disparities education into a hematology/oncology academic curriculum. We recommend further analysis of such curricula to improve fellowship education and patient outcomes with these interventions.

Addressing racial disparities in cancer care: A collaborative grant initiative.

A competitive grants program developed by the American Cancer Society and Pfizer Global Medical Grants funded 10 quality improvement projects aimed at reducing systemic barriers and addressing cancer disparities for Black men and women. This introduction details the purpose and scope of this program and addresses the potential for similar projects addressing disparities along the cancer care continuum.

Hormonal treatment for newly diagnosed metastatic prostate cancer: a population-based study from the California cancer registry.

To evaluate how often men with metastatic prostate cancer (mPC) receive standard of care treatment with androgen deprivation therapy (ADT). Men aged ≥20 years with newly diagnosed mPC (stage IV) between 2010 and 2018 were identified using California Cancer Registry data. Receipt of hormonal therapy as initial cancer treatment was examined by patient/tumor characteristics at time of diagnosis. Chi-square tests and logistic regression, adjusted for covariates, were performed to assess association between receipt of hormonal therapy and patient/tumor characteristics. We identified 13,680 men with newly diagnosed mPC, of which 3637 had local metastasis (N1) only while 9596 had distant metastasis (M1) with or without N1 disease. 21.8 % (n = 2980) of men did not receive ADT. The highest rate of receiving ADT was among men between ages 75-84 (81.6%) and the lowest rate was in men over 85 (76.0%). Asian men had the largest proportion receiving ADT (n = 962, 81.5%) with remaining subgroups having similar proportion of men receiving ADT (76.8% to 77.2%). Once adjusted for covariates, regression results showed men with a higher Gleason score (8-10) were more likely to receive ADT (OR 2.04, 1.82-2.27, p = < 0.001) as well as men with distant sites of metastatic disease (OR 4.02, 3.62-4.46, p = < 0.001). Men residing in neighborhoods with the lowest socioeconomic status were least likely to receive ADT (OR 0.79, 0.68-0.93, p = 0.0032). No differences in receipt of ADT were observed by race/ethnicity. Despite significant advancements in the treatment of mPC in recent years, over one-fifth of patients did not receive ADT, which is the backbone for all new systemic therapies. This dataset might help address some of the prostate cancer care disparities in California.

Risk factors and early prevention of skin cancer in rural older outdoor workers: A scoping review

Skin cancer risk increases with age and prolonged exposure to ultraviolet radiation (UVR), particularly in rural geographical locations and for individuals with light skin complexions. However, the impact of UVR-induced skin cancer risk and sun-protective behaviors in rural older populations working outdoors has yet to be explored. A scoping review was conducted to fill this gap, with 12 articles meeting the inclusion criteria of aged 50 years and older among rural outdoor workers. Skin cancer risk factors, prevention strategies, and barriers to sun-protective behaviors were summarized for each study. The scoping review addressed some key differences in age-related effects of UVR among rural older outdoor workers compared to studies among adults in general. Findings have policy and research implications that highlight the need to design feasible preventive strategies to reduce rural disparities in cancer care and enhance access to preventive services for this high-risk population.

Disparities in Initial Thyroid Cancer Care by Hospital Treatment Volume: Analysis of 52,599 Cases in California.

Background: Racially minoritized patients with thyroid cancer are less likely to receive high-quality and guideline-concordant care. Inaccessibility of high-volume centers may contribute to inequalities in thyroid cancer outcomes. This study sought to understand the extent to which access to higher volume thyroid cancer centers is associated with patient outcomes. Methods: We queried linked California Cancer Registry and California Office of Statewide Health Planning and Development databases for thyroid cancer patients who received thyroid surgery between 1999 and 2017. Hospitals were stratified by their median annual volume of thyroid cancer operations: ultra-low volume (0-5 cases/year), low-volume (6-25 cases/year), mid-volume (26-50 cases/year), and high-volume (>50 cases/year). We analyzed the rates of complications, rates of reoperation for cancer recurrence, use of radioactive iodine (131I), and mortality by median hospital volume of thyroid surgery. A multivariable regression controlled for high-risk tumor features. Differences in access by center volume were assessed based on patient demographics. Results: We studied 52,599 thyroid cancer patients who underwent thyroidectomy. Patients who underwent thyroidectomy at ultra-low volume centers were more likely to undergo reoperations for recurrent/persistent disease compared with patients at low- (odds ratio [OR] 1.17 [CI 1.02-1.35]), mid- (OR 1.25 [CI 1.06-1.46]), and high-volume centers (OR 1.26 [CI 1.03-1.56]). Patients who received thyroid operations at ultra-low volume centers were also less likely to receive guideline-concordant 131I ablation compared with patients at higher volume centers (OR 0.77 [CI 0.72-0.82]). A pair-wise comparison between all volume categories for all outcomes revealed no statistically significant differences in outcomes between low-, mid-, or high-volume centers. Only ultra-low volume centers had significantly higher rates of adverse outcomes. Ultra-low volume centers were disproportionately accessed by women (p < 0.05), Hispanic, Asian/Pacific Islander, and American Indian people (p < 0.01), those from the lowest three quintiles of socio-economic status (p < 0.01), and the uninsured and those on Medicaid or Medicare (p < 0.01) when compared with higher volume centers. Conclusions: Patients receiving thyroid cancer surgery at centers performing ≤5 such operations per year were more likely to require reoperation for recurrent/persistent disease and less likely to receive appropriate 131I ablation. Ultra-low volume centers served higher proportions of socially and economically marginalized communities.

ESMO/ASCO Recommendations for a Global Curriculum in Medical Oncology Edition 2023.

The European Society for Medical Oncology (ESMO) and ASCO are publishing a new edition of the ESMO/ASCO Global Curriculum (GC) with contributions from more than 150 authors. The purpose of the GC is to provide recommendations for the training of physicians in medical oncology and to establish a set of educational standards for trainees to qualify as medical oncologists. This edition builds on prior ones in 2004, 2010, and 2016 and incorporates scientific advances and input from an ESMO ASCO survey on GC adoption conducted in 2019, which revealed that GC has been adopted or adapted in as many as two thirds of the countries surveyed. To make GC even more useful and applicable, certain subchapters were rearranged into stand-alone chapters, that is, cancer epidemiology, diagnostics, and research. In line with recent progress in the field of multidisciplinary cancer care new (sub)chapters, such as image-guided therapy, cell-based therapy, and nutritional support, were added. Moreover, this edition includes an entirely new chapter dedicated to cancer control principles, aiming to ensure that medical oncologists are able to identify and implement sustainable and equitable cancer care, tailored to local needs and resources. Besides content renewal, modern didactic principles were introduced. GC content is presented using two chapter templates (cancer-specific and non-cancer-specific), with three didactic points (objectives, key concepts, and skills). The next step is promoting GC as a contemporary and comprehensive document applicable all over the world, particularly due to its capacity to harmonize education in medical oncology and, in so doing, help to reduce global disparities in cancer care.

Differences in Receipt of Immunotherapy Treatment Among Patients With Head and Neck Cancer

The US Food and Drug Administration approved immune checkpoint inhibitors (immunotherapy) for select cases of head and neck squamous cell carcinoma (HNSCC) in 2016. However, it is unclear whether there are clinical or sociodemographic differences among patients receiving immunotherapy as part of their care. Given the known disparities in head and neck cancer care, we hypothesized that there are differences in receipt of immunotherapy among patients with HNSCC based on clinical and nonclinical characteristics. To characterize clinical and nonclinical factors associated with receipt of immunotherapy among older patients with HNSCC. This retrospective cohort study included patients 65 years or older diagnosed with HNSCC (n = 4860) in a community oncology care setting. Electronic health records from Navigating Cancer were assessed from January 1, 2017, to April 30, 2022. Multivariable logistic regression was used to characterize clinical (tumor stage [localized vs advanced] and anatomical subsite [oropharyngeal vs nonoropharyngeal]) and nonclinical (age, smoking history, race and ethnicity, sex, and marital status) factors associated with receipt of immunotherapy. In the study cohort of 4860 patients, 3593 (73.9%) were men; 4230 (87.0%) were White and 630 (13.0%) were of other races. A total of 552 patients (11.4%) had received immunotherapy. After adjusting for covariates, in the final model, White patients with HNSCC had 80% increased odds of receiving immunotherapy (adjusted odds ratio [AOR], 1.80 [95% CI, 1.30-2.48]) compared with patients of other races. There were no statistically significant differences in the odds of receiving immunotherapy based on age, sex, or smoking history. Patients with nonoropharyngeal disease were significantly more likely to receive immunotherapy than those with oropharyngeal cancer (AOR, 1.29 [95% CI, 1.05-1.59]), as were those with advanced compared with local disease (AOR, 2.39 [95% CI, 1.71-3.34]). The findings of this cohort study suggest that among older patients with HNSCC, White patients may be more likely to receive immunotherapy as part of their care. Equitable access to immunotherapy and other treatment options will reduce cancer-related health disparities and improve survival of patients with HNSCC.

375. RURAL PATIENTS HAVE A PROLONGED INPATIENT RECOVERY PROCESS AFTER ESOPHAGECTOMY COMPARED TO NON-RURAL PATIENTS AT A HIGH-VOLUME ESOPHAGEAL PROGRAM

Abstract Background Geographic access to care plays a large role in health disparities in esophageal cancer care, with rural individuals often travelling further to access complex healthcare services. We sought to characterize peri-operative outcomes in patients undergoing esophagectomy for loco-regional cancer at a single academic tertiary care center based on geographic home location. We hypothesize that rural patients will have worse peri-operative outcomes after esophagectomy, despite receiving care at the same high-volume hospital. Methods Prospectively collected data from patients with loco-regional esophageal cancer who underwent esophagectomy at a single academic medical center between 2003 to 2022 were analyzed based on county. The counties were aggregated into previously existing state-level ‘metropolitan’ versus ‘rural’ designations per the Rural Health Information Hub guidelines. Distance traveled by the patients were calculated using driving distance between the patient’s reported zip code and hospital address. Demographics, pre-operative treatment, surgical complications, post-operative outcomes, length of stay (LOS), and mortality of the two groups were analyzed using chi-squared, paired t-tests, and single-factor ANOVA. Results The cohort consisted of 1545 patients with 76.0% from metropolitan counties and 24.0% from rural counties. Patients were more likely to be male in both groups (p = 0.004), with no significant differences in pre-operative characteristics. Both groups had similar rates of pre-operative chemotherapy (p = 0.11) and pre-operative radiation (p = 0.58). Rural patients traveled greater distances for healthcare services compared to metropolitan patients (rural: 192.4 ± 101.2 miles; metropolitan: 63.4 ± 36.7 miles; p &amp;lt; 0.001). Post-operatively rural patients had higher rates of pneumonia (p = 0.04) and more initial ICU visits (p &amp;lt; 0.001). Rural patients had longer ICU LOS (p &amp;lt; 0.001), but no difference in total hospital LOS (p = 0.28) or 30-day mortality (p = 0.35). Conclusion Rural patients tended to have a more complex inpatient recovery process after esophagectomy despite receiving surgery at the same high-volume institution and no differences in pre-operative characteristics (BMI, smoking history, and co-morbidities). It is unclear as to the reason for differences in pneumonia rates and ICU stays. Future studies should focus on the impact of rural location on disparities for individuals undergoing esophagectomy.

Geographic Disparity of Outcome in Patients With Cancer Over Decades: The Surveillance, Epidemiology, and End Results

BackgroundImprovements in prevention, early detection, and effective cancer therapy have decreased cancer-related mortality; however, significant health disparities exist. Therefore, we investigated the impact of these disparities on survival. MethodsIn the Surveillance, Epidemiology, and End Results, we identified 784,341 patients with cancer between 1990 and 2016 in Georgia, 68,493 between 1990 and 1999; 371,353 between 2000 and 2009; and 322,932 between 2010 and 2016. We assessed the overall survival (OS) of patients with all cancers, chronic myeloid leukemia (CML), and lung cancer, given the dramatic improvement in outcomes in patients with CML since 2000 compared to the generally considerably worse outcomes in lung cancer. In addition, we assessed the distance from each county to the Georgia Cancer Center (GCC) or the National Cancer Institute-designated Cancer Center (NCI-CC). ResultsThe 5-year OS of patients with any cancer was 55%, and the 5-year OS of each county ranged from 33% to 82% (interquartile range, 51%-65%) (P < .001). In patients with lung cancer and CML, the 5-year OS rates were 15% and 52%, respectively. The geographic differences between counties were relatively small and constant over time for patients with lung cancer. However, geographic differences were more prominent in patients with CML and widened after the introduction of modern therapies. Multivariate Cox regression showed that age, median county income, race, and distance to GCC or NCI-CC were predictive factors. ConclusionsSignificant disparities in cancer care exist among geographic locations. Geographic differences in survival appear more prominent when highly effective therapies are available.

Radiotherapy resources in Brazil (RT2030): a comprehensive analysis and projections for 2030

The demand for radiotherapy in Brazil is unfulfilled, and the scarcity of data on the national network hampers the development of effective policies. We aimed to evaluate the current situation, estimate demands and requirements, and provide an action plan to ensure access to radiotherapy for those in need by 2030. The Brazilian Society for Radiation Oncology created a task force (RT2030) including physicians, medical physicists, policy makers, patient advocates, and suppliers, all of whom were major stakeholders involved in Brazilian radiotherapy care. The group was further divided into seven working groups to address themes associated with radiotherapy care in Brazil. From March 1, 2019, to Aug 3, 2020, there were monthly meetings between the group's leaders and the Central Committee and six general meetings. First, a comprehensive search of all different national databases was done to identify all radiotherapy centres. Questionnaires evaluating radiotherapy infrastructure and human resources and assing the availability, distribution, capacity, and workload of resources were created and sent to the radioprotection supervisor of each centre. Results were analysed nationally and across the country's regions and health-care systems. A pre-planned review of available databases was done to gather data on active radiation oncology centres and the distribution of radiotherapy machines (linear accelerators [LINACs]) across Brazil. We used national population and cancer incidence projections, recommended radiotherapy usage from the medical literature, and national working patterns to project radiotherapy demands in 2030. An action plan was established with suggestions to address the gaps and meet the demands. The database search yielded 279 centres with an active radiotherapy registry. After applying predefined exclusion criteria, 263 centres were identified that provided external beam radiotherapy machines with or without brachytherapy. All 263 operational centres answered the questionnaires sent on Dec 9, 2019, which were then returned between Jan 1 and June 30, 2020. There were 409 therapy machines, 646 radiation oncologists, 533 physicists, and 230 989 patients undergoing radiotherapy (150 628 [65·2%] in the public health-care system and 80 937 [35·0%] in private). The mean annual occupation rate was 566 patients per treatment machine (SD 250). The number of residents per treatment machine ranged from 258 333 to 1 800 000. Technology availability varied considerably among regions and systems. In 2030, 639 994 new cancer cases are expected, which will require 332 797 radiotherapy courses. Therefore, 530 LINACs, 1079 radiation oncologists, and 1060 medical physicists will be needed. The expected increase in cancer incidence in the coming years will probably increase the disparities in cancer care and the burden for Brazilian patients. We provide a roadmap of the current situation and the particularities of the Brazilian radiotherapy network, which can serve as a starting point for cancer policy planning to improve this scenario.

Inequalities in access to treatment in Argentina: Differences in management of CLL and multiple myeloma?

Health equity is today an important objective to evenly reach the population among different health care systems. This article will focus on diagnosis and treatment access inequalities in Argentina.Although different aspects must be optimized to overcome access barriers worldwide, access inequalities in some regions of Argentina may depend basically on the type of health coverage or insurance. Health care in Argentina is divided into Public, Social security and Private care systems. Access to diagnosis and disease monitoring will vary according whether the patient is under each of these systems. Reducing inequalities may help target some important aspects not covered today and that may directly impact patients' outcome. Disparities in health cancer care were analyzed according to Public, Social security and Private sectors. A disadvantage in resource access, inadequate funding and limited medical infrastructures are common characteristics of the public health care systems. In our country the disparity between the public and private sectors in terms of timely diagnosis, stage of disease at diagnosis, accuracy of diagnosis, access to novel agents and transplantation is notorious, with the public sector lagging behind in access to diagnostic and treatment resources. While the Private sector has treatment outcomes comparable to those of high-income countries, challenges remain in the Public sector for patients who rely on early and accurate diagnosis and timely access to treatment. There is an urgent need to provide equitable care for multiple myeloma and CLL patients and reduce the emotional and financial consequences of the disease for the patient.A survey about diagnosis and therapeutic resources was conducted between April and May 2023 among large centers in the Public, Social security and Private systems. A total of 49 hematologists from 31 institutions from five provinces of Argentina participated in the survey. We observed differences between the different systems with more access for the Private system on genetic diagnosis (FISH-IGVH access). More CLL patients in the public and social security systems were treated with CIT reflecting the inaccessibility in these sectors of more expensive targeted therapies rather than a gap in information since the Public centers surveyed were large hospitals with knowledgeable physicians. Access to different treatments both in first-line and relapsed settings was more equitable in the treatment of multiple myeloma for the different systems with the exception of access to daratumumab in first-line that was extremely infrequent in the public coverage. With increasing cost and treatment complexity as the introduction of CARTs and BITEs for CLL and MM, the gap will probably deepen more if the problem is not treated comprehensively by all the actors of the health sector: government, physicians, patients' organizations and pharmaceutical companies.

Swahili translation and cultural adaptation of the pediatric patient-reported outcomes version of the common terminology criteria for adverse events (PRO-CTCAE)

BackgroundThe pediatric patient-reported outcomes version of the common terminology criteria for adverse event measure was developed and validated for use in pediatric cancer clinical trials to better capture the symptom experiences through direct self-report. The study aim was to develop and validate a Swahili language version of the patient-reported outcomes version of the common terminology criteria for adverse event measure.MethodsThe pediatric version of 15 core symptom adverse events, and the corresponding questions, were selected from the patient-reported outcomes version of the common terminology criteria for adverse event library, then forward and back translated into Swahili by bilingual translators. The translated items were further refined using concurrent cognitive interviewing. Each round of interviews included five children, ages 8–17 years-old, receiving cancer therapy at Bugando Medical Centre, the cancer referral hospital for Northwest Tanzania, and continued until at least 80% of participants understood the question.ResultsThree rounds of cognitive interviews were completed involving 13 patients and 5 caregivers. Among patients, 50% of questions (19/38) were fully comprehended after the first interview round. Two Adverse Events (anxiety and peripheral neuropathy) were the most difficult for participants to understand, associated with education level and experience. Goal comprehension was achieved after three rounds of interviews with no further revisions required. All parents in the first cognitive interview group comprehended the survey, with no additional revisions.ConclusionA Swahili patient-reported outcomes version of the common terminology criteria for adverse event was effective in eliciting patient-reported Adverse Events related to cancer treatment, with good comprehension for children aged 8–17 years. This survey is important to incorporate patient self-reporting of symptomatic toxicities and is an effective tool to increase capacity for pediatric cancer clinical trials throughout East Africa, further reducing global disparities in cancer care.

A REVIEW OF CHALLENGES AND PROSPECTS OF MOBILE MAMMOGRAPHY SCREENING IN DEVELOPING COUNTRIES

Abstract Breast cancer is the most common cancer among women worldwide, accounting for approximately 25% of all female cancer cases. Given the increasing impact of breast cancer in developing countries, early detection and timely treatment are crucial in reducing morbidity and mortality associated with the disease. Mammography screening is a well-established method for early detection, as it can identify breast cancer at an early stage when the chances of successful treatment are higher. Mobile mammography screening has the potential to significantly improve early detection and reduce mortality rates associated with breast cancer in developing countries. However, various challenges still impede the full realization of its benefits. This review article aims to identify and explore the challenges and prospects of implementing mobile mammography screening programs in developing countries, and to provide recommendations on how to overcome these obstacles. Overall, the future of mobile mammography screening in developing countries can be promising, with opportunities for technological advancements, increased global cooperation, and ongoing research to further enhance the effectiveness of these programs. By seizing these opportunities and addressing the challenges related to accessibility, affordability, human resources, cultural and social factors, and infrastructure, mobile mammography screening can make a significant impact on the lives of women in developing countries and contribute to reducing global disparities in breast cancer care. Several successful mobile mammography screening projects in low- and middle-income countries showcase the potential for such programs to improve access to early detection services, raise breast cancer awareness, and ultimately reduce breast cancer mortality rates. By adapting best practices and lessons learned from these projects, other low- and middle-income countries can develop and implement mobile mammography screening programs tailored to their unique contexts and resource constraints.

How patient-clinician education can strengthen partnerships and promote tangible actions to improve clinical trial diversity in breast and lung cancer trials.

6510 Background: Some of the greatest disparities in cancer care are related to clinical trial access for our patients. To address the racial/ethnic disparities in breast and lung cancer clinical trials, a tethered educational initiative was designed to empower patients, assess current clinician perceptions/practices, and improve awareness of real-world perspectives of clinical trials. Methods: Two, one-hour online, interactive, video-based programs were designed for patients, caregivers, and providers. This patient/caregiver program was hosted on CancerCoachLive and MedLive in November, 2022, while the provider program was hosted on ClinicalSeriesLive in December, 2022 and will remain on-demand until December 2023. This initiative was conducted in collaboration with TOUCH, the Black Breast Cancer Alliance, BlackDoctors.org, Moffitt Cancer Center, CancerCare, and the Lung Cancer Research Foundation. Herein, we report on an analysis from patients and providers regarding clinical trial diversity, behavioral impact, and qualitative insights. Results: As of data cut-off (02/10/23), 1,425 participants have engaged across both educational programs. Of participating patients, 46% were non-White (non-Hispanic), 36% were in remission, 36% were not on active treatment, and 29% were newly diagnosed. Following the program 81% were motivated to take one or more actions over the next two months: the most common actions being to research clinical trials (38%) or discuss clinical trials with a clinician (19%). Post-activity, 79% were confident to very confident discussing clinical trials with a clinician. Critical data related to clinician preferences was assessed and demonstrated a 23% increase in confidence from pre- to post-activity in improving diversity in clinical trial participation with preferences observed in both breast and lung cancers to offer clinical trials for newly diagnosed and second recurrence settings. Of those who are being offered clinical trials in the community setting, there was a higher likelihood for patients to be offered a clinical trial if their subtype was HER2+ breast cancer subtype or NSCLC with an actionable mutation. Data collection continues as this initiative is ongoing. Qualitative data including clinician write-in examples of behavioral impact and patient perspectives from the interviews will be shared. Conclusions: The outcomes discussed herein reveal a willingness from patients/caregivers to engage in clinical trial discussions and participate in clinical trials, if eligible. These educational programs positively impacted clinician motivation to address barriers to enrollment and clinical trial eligibility with their patients. Real-world accounts of patient experiences provide different perspectives that can help improve approaches to improve clinical trial diversity.
