Post-Mastectomy Patients in an Urban Safety-Net Hospital: How Do Safety-Net Hospital Breast Reconstruction Rates Compare to National Breast Reconstruction Rates?

Background Breast reconstruction (BR) has documented psychological benefits following mastectomy. Yet, racial/ethnic minority groups have lower reported rates of BR. We sought to evaluate the rate, type, and outcome of BR in a racially and ethnically diverse population within a safety-net hospital system. Methods All patients who underwent mastectomy between October 2015 and July 2019 at Harbor-UCLA Medical Center were retrospectively examined. Rates and type of BR were analyzed according to patient characteristics (race/ethnicity, age, and body mass index), smoking status, cancer stage, and presence of diabetes mellitus. Breast reconstruction outcomes were also assessed. Results Of the 259 patients that underwent mastectomy, 87 (33.6%) received BR. Immediate BR was performed in 79 (30.5%) patients and delayed BR in 8 (3.1%). Of the 79 patients with immediate BR, 58 (73.4%) received implant-based BR and 21 (26.5%) autologous tissue. The BR failure rate was 10%, all implant-based. Increasing age and smoking negatively impacted BR rates. Black ( P =.331) and Hispanic ( P =.132) ethnicity were not independent predictors of decreased breast reconstruction. Conclusion This study demonstrated that the rate, type, and quality of BR in this integrated safety-net hospital within a diverse population are comparable to national rates. When made available, historically underrepresented minority patients of Black and Hispanic ethnicity utilize BR.

The randomized trial of mammography screening that was not—A cautionary tale

Two randomized trials were conducted in Canada in the 1980s to test the efficacy of breast cancer screening. Neither of the trials demonstrated benefit. Concerns were raised regarding serious errors in trial design and conduct. Here we describe the conditions that could allow subversion of randomization to occur and the inclusion of many symptomatic women in a screening trial. We examine anomalies in data where the balance would be expected between trial arms. “Open book” randomization and performance of clinical breast examination on all women before allocation to a trial arm allowed women with palpable findings to be mis-randomized into the mammography arm. Multiple indicators raising suspicion of subversion are present including a large excess in poor-prognosis cancers in the mammography trial arm at prevalence screen. Personnel described shifting of women from the control group into the mammography group. There is compelling evidence of subversion of randomization in Canadian National Breast Screening Study. Mis-randomization of even a few women with advanced breast cancer could markedly affect measured screening efficacy. The Canadian National Breast Screening Study trials should not influence breast screening policies.

Socio-Territorial Inequities in the French National Breast Cancer Screening Programme—A Cross-Sectional Multilevel Study

Background. France implemented in 2004 the French National Breast Cancer Screening Programme (FNBCSP). Despite national recommendations, this programme coexists with non-negligible opportunistic screening practices. Aim. Analyse socio-territorial inequities in the 2013–2014 FNBCSP campaign in a large sample of the eligible population. Method. Analyses were performed using three-level hierarchical generalized linear model. Level one was a 10% random sample of the eligible population in each département (n = 397,598). For each woman, age and travel time to the nearest accredited radiology centre were computed. These observations were nested within 22,250 residential areas called “Îlots Regroupés pour l’Information Statistique” (IRIS), for which the European Deprivation Index (EDI) is defined. IRIS were nested within 41 départements, for which opportunistic screening rates and gross domestic product based on purchasing power parity were available, deprivation and the number of radiology centres for 100,000 eligible women were computed. Results. Organized screening uptake increased with age (OR1SD = 1.05 [1.04–1.06]) and decreased with travel time (OR1SD = 0.94 [0.93–0.95]) and EDI (OR1SD = 0.84 [0.83–0.85]). Between départements, organized screening uptake decreased with opportunistic screening rate (OR1SD = 0.84 [0.79–0.87]) and départements deprivation (OR1SD = 0.91 [0.88–0.96]). Association between EDI and organized screening uptake was weaker as opportunistic screening rates and as département deprivation increased. Heterogeneity in FNBCSP participation decreased between IRIS by 36% and between départements by 82%. Conclusion. FNBCSP does not erase socio-territorial inequities. The population the most at risk of dying from breast cancer is thus the less participating. More efforts are needed to improve equity.

Breast Cancer Early Detection in Eswatini: Evaluation of a Training Curriculum and Patient Receipt of Recommended Follow-Up Care

PURPOSE Breast cancer (BC) is detected at late stages in sub-Saharan Africa. We piloted a BC early-detection program in Eswatini aimed at increasing breast health knowledge and clinical skills. We also aimed to determine the proportion of patients with breast abnormalities who completed referral to breast specialty clinics. METHODS Nurses and counselors from five human immunodeficiency virus and/or antiretroviral therapy clinics underwent training in BC and clinical breast examination (CBE). We compared knowledge and skill examinations completed before, immediately after, and 90 days after training. Nurses then screened female clinic patients ≥ 18 years for breast symptoms, examined those with symptoms, and referred women with CBE abnormalities to a surgeon or the national breast clinic. Consenting women were contacted at 30 and 60 days after screening to determine if they had completed referral. RESULTS In 2019, 44 nurses underwent training. Median scores (interquartile range) on pretraining, immediate post-training, and 90-day post-training knowledge examinations were 17.5 (16-19), 20 (19-21), and 20 (19-21), respectively. Median scores (interquartile range) on pretraining, immediate post-training, and 90-day post-training skills examinations were 10 (7-11), 23 (21.5-25), and 23 (22-24), respectively. Compared with pretraining scores, post-training scores were significantly improved ( P < .0001 for all comparisons). From June 2019 to April 2020, a total of 9,502 clinic patients were screened for breast symptoms: 150 (2%) underwent CBE, 93 (62%) were referred for further evaluation, and 88 (97%) were included in the study. Of those, 54 (61%) completed referral. Referral completion was not associated with age, employment, relationship status, or prior experiences related to BC. CONCLUSION The program's training curriculum improved breast health knowledge and clinical skills. Efforts are needed to improve patients' receipt of recommended evaluation for breast abnormalities.

Translational Research in Cancer Screening: Long-Term Population-Action Bridges to Diffuse Adherence

The population-level implementation of innovative, evidence-based medical recommendations for adopting health-behaviors depends on the last link in the translation chain: the users. “User-friendly” medical interventions aimed at engaging users to adopt recommended health behaviors are best developed in a collaborative bio-medical and social sciences setting. In the 1990s, National Breast and Colorectal Cancer Early Detection Programs were launched at the Israeli Department of Community Medicine and Epidemiology. Operating under the largest HMO (Health Maintenance Organization) in Israel (“Clalit Health Services”), the department had direct access to HMO community primary-care clinics’ teams, insured members, and medical records. Academically affiliated, the department engaged in translational research. In a decades-long translational process, this multi-disciplinary unit led a series of interventions built upon basic and applied behavioral/social science phenomena such as framing, “Implementation Intentions,” and “Question-Behavior-Effect”. A heterogeneous team of disciplinary specialists created an integrated scientific environment. In order to enhance screening, the team focused on the establishment of a systematic mechanism actively inviting programs’ “users” (average-risk targeted individuals on the national level), and continuously applied social and health psychology concepts to study individuals’ perceptions, expectations, and needs related to cancer screening. The increase in adherence to screening recommendations was slow and incremental. A decrease in late-stage breast and colorectal cancer diagnoses was observed nationally, but participation was lower than expected. This paper positions screening adherence as a unique challenge and proposes new social and network avenues to enhance future participation.
