RESUMEN

BACKGROUND: The generation of data capturing the risk-benefit ratio of incorporating carboplatin (Cb) to neoadjuvant chemotherapy (NACT) for triple-negative breast cancer (TNBC) in a clinical practice setting is urgently needed. Tumour-infiltrating lymphocytes (TILs) have an established role in TNBC receiving NACT, however, the role of TIL dynamics under NACT exposure in patients receiving the current standard of care is largely uncharted. METHODS: Consecutive TNBC patients receiving anthracycline-taxane [A-T] +/- Cb NACT at three Institutions were enrolled. Stromal-TILs were evaluated on pre-NACT and residual disease (RD) specimens. In the clinical cohort, propensity-score-matching was used to control selection bias. RESULTS: In total, 247 patients were included (A-T = 40.5%, A-TCb = 59.5%). After propensity-score-matching, pCR was significantly higher for A-TCb vs A-T (51.9% vs 34.2%, multivariate: OR = 2.40, P = 0.01). No differences in grade ≥3 haematological toxicities were observed. TILs increased from baseline to RD in the overall population and across A-T/A-TCb subgroups. TIL increase from baseline to RD was positively and independently associated with distant disease-free survival (multivariate: HR = 0.43, P = 0.05). CONCLUSIONS: We confirmed in a clinical practice setting of TNBC patients receiving A-T NACT that the incorporation of weekly Cb significantly improved pCR. In addition, A-T +/- Cb enhanced immune infiltration from baseline to RD. Finally, we reported a positive independent prognostic role of TIL increase after NACT exposure.

RESUMEN

BACKGROUND: Caregivers of children with developmental disabilities (DDs) in Ethiopia experience stigma and exclusion. Due to limited existing services and substantial barriers to accessing care, they often lack support. Caregiver empowerment could help address injustices that hinder their capacity to support their child as they would like. The aim of this study was to explore the meaning and potential role of empowerment for caregivers raising a child with a DD and how empowerment was situated in relation to other priorities in service development. METHODS: This was a qualitative phenomenological study. Semi-structured interviews were conducted in Amharic and English with caregivers of children with a DD (n = 15), clinicians (n = 11), community-based health extension workers (n = 5), representatives of non-governmental organisations working with families with DDs (n = 17), and representatives of local authorities in health, education, and social care (n = 15). Data were analysed thematically. RESULTS: Three main themes were developed: "Barriers to exercising caregivers' agency"; "Whose decision is it to initiate empowerment?"; and "Supporting caregivers through support groups". Caregiver capacity to do what they thought was best for their child was undermined by poverty, a sense of hopelessness, experience of domestic abuse and multiple burdens experienced by those who were single mothers. Caregivers were nonetheless active in seeking to bring about change for their children. Caregivers and professionals considered support groups to be instrumental in facilitating empowerment. Participants reflected that caregiver-focused interventions could contribute to increasing caregivers' capacity to exercise their agency. A tension existed between a focus on individualistic notions of empowerment from some professionals compared to a focus on recognising expertise by experience identified as vital by caregivers. Power dynamics in the context of external funding of empowerment programmes could paradoxically disempower. CONCLUSION: Caregivers of children with DDs in Ethiopia are disempowered through poverty, stigma, and poor access to information and resources. Shifting power to caregivers and increasing their access to opportunities should be done on their own terms and in response to their prioritised needs.

RESUMEN

BACKGROUND: The integration of residual cancer burden (RCB) and post-treatment Ki67 as residual proliferative cancer burden (RPCB) has been proposed as a stronger predictor of long-term outcome in unselected patients with breast cancer (BC) undergoing neoadjuvant chemotherapy (NACT), as compared with RCB. However, no specific analysis in hormone-receptor-positive (HR+) human epidermal growth receptor 2-negative (HER2-) BC is available so far. MATERIALS AND METHODS: A cohort of 130 patients with HR+/HER2- BC who underwent NACT between 2000 and 2014 was included. Archival surgical specimens were evaluated for RCB. RPCB was calculated by combining RCB and Ki67 as previously described. Patients were categorized in four RCB and RPCB categories (pathological complete response and tertiles). Disease-free survival (DFS) and overall survival (OS) estimates were determined by Kaplan-Meier analysis and compared using the log-rank test. Overall change of χ2 and c-indexes were used to compare the performance of the prognostic models. RESULTS: RPCB was calculated for 85 patients. After a median follow up of 8.5 years, RCB was associated with OS (p = .048) but not with DFS (p = .152); RPCB was instead significantly associated with both DFS and OS (p = .034 and p < .001, respectively). In terms of OS, RPCB provided a significant amount of prognostic information beyond RCB (∆χ2 5.73, p < .001). In addition, c-index for OS prediction was significantly higher for RPCB as compared with RCB (0.79 vs. 0.61, p = .03). CONCLUSION: This is the first study evaluating RPCB in patients with HR+/HER2- BC treated with NACT. In this independent cohort, RPCB was a strong predictor of DFS and OS. The better performance of RPCB versus RCB was in part due to the ability of RPCB to discriminate a subgroup of patients with a particularly worse prognosis after NACT, who may be candidates for clinical trials evaluating novel adjuvant strategies. IMPLICATIONS FOR PRACTICE: The present work validated residual proliferative cancer burden (RPCB) as a strong predictor of long-term outcome in patients with hormone receptor-positive human epidermal growth receptor 2-negative (HR+/HER2-) breast cancer (BC) treated with neoadjuvant chemotherapy. In addition, results from the present study suggest RPCB as a promising tool to identify patients with HR+/HER2- BC who might potentially benefit from the inclusion in clinical trials evaluating novel or escalated postneoadjuvant treatment strategies because it allowed to discriminate a subgroup of patients with particularly poor prognosis despite having received subsequent endocrine therapy in the adjuvant setting.

RESUMEN

Children with developmental disabilities (DD) including intellectual disability and autism, experience exclusion from social life and education in Ethiopia. Including children with DD in mainstream inclusive classes has potential to expand access to education and uphold their right to learn alongside typically developing peers. However, inadequate support in inclusive settings can hinder their participation and educational achievement. This study explores the perspectives of stakeholders on the ways in which inclusive education can support the needs or exacerbate the challenges of children with DD in Addis Ababa, Ethiopia, and on recommendations to address the challenges. Thirty-nine participants with expertise or experience relevant to children with DD, including caregivers, educators, clinicians and other experts, took part in semi-structured interviews. Their responses were analysed using thematic template analysis. The themes developed identify four aspects which are most relevant to the potential positive and negative consequences of inclusive education for children with DD: learning and development, peer relationships, safety in school and inclusion in society. The themes encompass sub-themes of positive and negative consequences, and suggested improvements to facilitate positive effects. Identified priorities for action include enhanced teacher training, awareness-raising initiatives, tailoring infrastructure and manpower to safeguard children with DD and promoting government focus on successful inclusion. These recommendations can be implemented to facilitate well-structured inclusive education, where children with DD are supported to participate alongside typically developing peers, as well as to safeguard against the potential negative consequences of inclusion, paying sufficient attention to the distinctive needs of children with DD.

RESUMEN

A large gap in provision of services for children with developmental disabilities (DD) has been identified in Ethiopia, especially in the education system. Including children with disabilities in mainstream schools is encouraged by policies, but progress in this direction has been limited. This study aimed to explore stakeholders' perspectives on contextual factors relevant for inclusive education for children with DD in mainstream schools in Ethiopia, with a focus on Adis Ababa. Data were collected through semi-structured interviews with 39 local stakeholders, comprising caregivers of children with DD, school teachers and principals/managers, non-governmental organisation representatives, government officials, clinicians and academics/consultants. We used template analysis to code the data and map them onto domains of the Context and Setting dimensions of the Context and Implementation of Complex Interventions framework. Stakeholders discussed frameworks in the Legal and Ethical context endorsing the right of all children to education. However, they reported multiple reasons why children with DD in Ethiopia have limited access to education, either in special or mainstream schools. First, individual features, such as gender and support needs, discussed in the Epidemiological context, may affect the likelihood of a child with DD to be accepted in school. Transportation challenges are a key barrier in the Geographical context. Socio-economic and Socio-cultural contexts present barriers at the levels of the nation, school and family, mostly related to limited services and material and financial resources and limited awareness of DD. Stakeholders believe the currently limited but growing commitment in the Political context can support progress towards the removal of these barriers. Our findings can form the basis for development of an implementation plan that addresses such barriers and capitalises on existing facilitators.

RESUMEN

Most children with developmental disabilities (DD), such as intellectual disabilities and autism, live in low- and middle-income countries (LMICs), where services are usually limited. Various governmental, non-governmental and research organisations in LMICs have developed awareness-raising campaigns and training and education resources on DD in childhood relevant to LMICs. This study aimed to comprehensively search and review freely available materials in the academic and grey literature, aimed at awareness raising, training and education on DD among non-specialist professionals and community members in LMICs. We consulted 183 experts, conducted key-word searches in five academic databases, four grey-literature databases and seventeen customised Google search engines. Following initial screening, we manually searched relevant systematic reviews and lists of resources and conducted forwards and backwards citation checks of included articles. We identified 7327 articles and resources after deduplication. We then used a rigorous multi-step screening process to select 78 training resources on DD relevant to LMICs, of which 43 aimed at informing and/or raising awareness DD, 16 highlighted specific strategies for staff in health settings and 19 in education settings. Our mapping analysis revealed that a wealth of materials is available for both global and local use, including comics, children's books, flyers, posters, fact sheets, blogs, videos, websites pages, social media channels, handbooks and self-education guides, and training programmes or sessions. Twelve resources were developed for cross-continental or global use in LMICs, 19 were developed for and/or used in Africa, 23 in Asia, 24 in Latin America. Most resources were developed within the context where they were intended to be used. Identified gaps included a limited range of resources on intellectual disabilities, manuals for actively delivering training to staff in education settings and resources targeted at eastern European LMICs: future intervention development and adaptation efforts should address such gaps, to ensure capacity building materials exist for a sufficient variety of DD, settings and geographical areas. Beyond identifying these gaps, the value of the review lies in the compilation of summary tables of information on all freely available resources found, to support their selection and use in wider contexts. Information on the resource content, country of original development and copyright is provided to facilitate resource sharing and uptake.

RESUMEN

BACKGROUND: While most autism research is conducted in White Western samples, culture may affect perceptions and reporting of autistic traits. We explored how UK-based British and Egyptian/Sudanese communities perceive autism features. METHODS AND PROCEDURES: Nineteen participants self-identifying as British and 20 as Egyptian/Sudanese participated in focus group discussions on child development norms, and individual interviews on items of the Autism-spectrum Quotient: Children's version (AQ-Child; Auyeung et al., 2007), measuring autistic traits. Data were analysed using template analysis. OUTCOMES AND RESULTS: Three themes were developed: 1) Value judgements of behaviours; 2) Considerations on differences between children; 3) Problematic interpretations of AQ-Child items. These processes may affect how parents and community members report on children's autistic traits. Cross-cultural comparisons suggested subtle differences in interpretations and judgements, and British participants referred to age expectations and comparisons with other children more than Egyptian/Sudanese participants. However, within-group variability, sometimes attributed to socioeconomic status and generation, appeared larger than cross-cultural differences. CONCLUSIONS AND IMPLICATIONS: Our findings further the insights on influence of culture and within-community factors on reporting children's behaviour relevant to autism. These can inform the adaptation of screening tools in multi-cultural settings, to promote better autism recognition in communities where it may be underdiagnosed.

RESUMEN

LAY ABSTRACT: In sub-Saharan Africa, there are few services for children with developmental disabilities such as autism and intellectual disability. One way to support these children is to include them in mainstream schools. However, currently, African children with developmental disabilities are often excluded from mainstream education opportunities. People involved (e.g. teachers, families and children) can offer information on factors that could ease or interfere with inclusion. This article discusses the findings of published studies that explored the views of relevant groups on including children with developmental disabilities in mainstream schools in sub-Saharan Africa. We systematically searched the literature and identified 32 relevant articles from seven countries in sub-Saharan Africa. We found that unclear policies and insufficient training, resources and support for teachers often blocked the implementation of inclusive education. Factors in favour of inclusive education were the commitment of many teachers to include pupils with developmental disabilities and the work of non-governmental organisations (NGOs), which provided resources and training. This review suggests that motivated teachers should be provided with appropriate training, resources and support for inclusive education, directly and by promoting the work of NGOs.

RESUMEN

Approximately a half of breast tumors classified as HER2-negative exhibit HER2-low-positive expression. We recently described a high instability of HER2-low-positive expression from primary breast cancer (BC) to relapse. Previous studies reporting discordance in HER2 status between baseline biopsy and residual disease (RD) in patients undergoing neoadjuvant treatment did not include the HER2-low-positive category. The aim of this study is to track the evolution of HER2-low-positive expression from primary BC to RD after neoadjuvant treatment. Patients undergoing neoadjuvant treatment with available baseline tumor tissue and matched samples of RD (in case of no pCR) were included. HER2-negative cases were sub-classified as HER2-0 or HER2-low-positive (IHC 1+ or 2+ and ISH negative). Four-hundred forty-six patients were included. Primary BC phenotype was: HR-positive/HER2-negative 23.5%, triple-negative (TN) 35%, HER2-positive 41.5%. HER2-low-positive cases were 55.6% of the HER2-negative cohort and were significantly enriched in the HR-positive/HER2-negative vs. TN subgroup (68.6% vs. 46.8%, p = 0.001 χ2 test). In all, 35.3% of non-pCR patients (n = 291) had a HER2-low-positive expression on RD. The overall rate of HER2 expression discordance was 26.4%, mostly driven by HER2-negative cases converting either from (14.8%) or to (8.9%) HER2-low-positive phenotype. Among HR-positive/HER2-negative patients with HER2-low-positive expression on RD, 32.0% and 57.1% had an estimated high risk of relapse according to the residual proliferative cancer burden and CPS-EG score, respectively. In conclusion, HER2-low-positive expression showed high instability from primary BC to RD after neoadjuvant treatment. HER2-low-positive expression on RD may guide personalized adjuvant treatment for high-risk patients in the context of clinical trials with novel anti-HER2 antibody-drug conjugates.

RESUMEN

Although 1% is the recommended cut-off to define estrogen receptor (ER) positivity, a 10% cut-off is often used in clinical practice for therapeutic purposes. We here evaluate clinical outcomes according to ER levels in a monoinstitutional cohort of non-metastatic triple-negative breast cancer (BC) patients undergoing (neo)adjuvant chemotherapy. Clinicopathological data of 406 patients with ER < 10% HER2-negative BC treated with (neo)adjuvant chemotherapy between 01/2000 and 04/2019 were collected. Patients were categorized in ER-negative (ER < 1%; N = 364) and ER-low positive (1-9%, N = 42). At a median follow-up of 54 months, 88 patients had relapsed and 64 died. No significant difference was observed in invasive relapse-free survival (iRFS) and overall survival (OS) according to ER expression levels, both at univariate and multivariate analysis (5-years iRFS 74.0% versus 73.1% for ER-negative and ER-low positive BC, respectively, p = 0.6; 5-years OS 82.3% versus 76.7% for ER-negative and ER-low positive BC, respectively, p = 0.8). Among the 165 patients that received neoadjuvant chemotherapy, pathological complete response rate was similar in the two cohorts (38% in ER-negative, 44% in ER-low positive, p = 0.498). In conclusion, primary BC with ER1-9% shows similar clinical behavior to ER 1% BC. Our results suggest the use of a 10% cut-off, rather than <1%, to define triple-negative BC.

RESUMEN

About a half of HER2-negative breast cancer (BC) show HER2-low expression that can be targeted by new antibody-drug conjugates. The main aim of this study is to describe the evolution of HER2 expression from primary BC to relapse by including HER2-low category in both primary and recurrent BC samples. Patients with matched primary and relapse BC samples were included. HER2 was evaluated according to ASCO/CAP recommendations in place at the time of diagnosis. A cutoff of >10% cells staining for HER2-positivity was applied. HER2-negative cases were sub-classified as HER2-low (IHC = 1 + /2+ and ISH not amplified), or HER2-0 (IHC-0). 547 patients were included. The proportion of HER2-low cases was 34.2% on the primary tumor and 37.3% on the relapse samples. Among HER2-negative cases, HER2-low status was more frequent in HR-positive vs triple-negative tumors (47.3% vs 35.4% on primary tumor samples, 53.8% vs 36.2% on relapse samples). The overall rate of HER2 discordance was 38.0%, mostly represented by HER2-0 switching to HER2-low (15%) and HER2-low switching to HER2-0 (14%). Among patients with a primary HER2-negative tumor, the rate of HER2 discordance was higher in HR-positive/HER2-negative vs triple-negative cases (45.5% vs 36.7% p = 0.170). This difference was mostly driven by cases switching from HER2-0 to HER2-low. HER2-low expression is highly unstable during disease evolution. Relapse biopsy in case of a primary HER2-0 tumor may open new therapeutic opportunities in a relevant proportion of patients.

RESUMEN

BACKGROUND: Despite endocrine therapy being the mainstay of treatment for hormone receptor positive (HR+)/HER2- metastatic breast cancer, patients at risk of visceral crisis or doubt for endocrine sensitivity are still offered first-line chemotherapy. Maintenance hormonal therapy is generally offered at the discontinuation of chemotherapy. The MAINtenance Afinitor study is a randomised, phase III trial comparing maintenance everolimus combined with aromatase inhibitors (AIs) versus AI monotherapy in patients with disease control after first-line chemotherapy. METHODS: Patients with stable disease, partial response or complete response after first-line chemotherapy were randomised to everolimus plus AIs (exemestane or letrozole or anastrozole) or to AIs alone. Primary aim was progression-free survival (PFS). Secondary aims included response rate, safety and overall survival (OS). RESULTS: In total, 110 patients were randomised to everolimus + AIs (n = 52) or to AIs (n = 58). Median PFS was 11.0 months (95% confidence interval [CI] 8.1-13.8) in the everolimus + AI arm and 7.2 months (95% CI 4.7-10.9) in the AI monotherapy arm (hazard ratio [HR] 0.71, 95% CI 0.47-1.06). Objective response rate was 22.4% in everolimus + AI arm and 19.2% in AI monotherapy arm. A higher proportion of disease progression as best response was reported in the AI monotherapy arm (28.8% versus 14.3%). Median OS was 35.7 months (95% CI 26.0-47.8) in the combination arm versus 33.5 (95% CI 26.4-42.7) in the AI alone arm (HR 1.0, 95% CI 0.61-1.62). CONCLUSIONS: EVE + AIs did not significantly impact on the outcome of metastatic breast cancer patients deemed suitable for first-line chemotherapy. Also taking into account treatment tolerability, maintenance endocrine therapy remains the standard. TRIAL REGISTRATION: EudraCT: 2013-004153-24.
