Elderspeak is often used when talking to older individuals and is characterized by a slower and/or louder speech, a patronizing tone, etc. A part of the reason of such communication can be found in the actual context of negative view of aging. However, the link between view of aging and elderspeak has never been objectively studied in oncology. Therefore, 40 healthcare professionals (physicians and medical students) record a podcast where they have to explain an endocrine therapy to two fictional patients (40 vs 70 years old). Results show that when participants explained the treatment to the older patient, they used shorter utterances and made more repetitions. They also evoked fewer side effects such as sexual issues. Moreover, reduction of length of utterances and of word-per-minute rate was observed for older patient when participants have a positive view of aging but for both patients when they have a negative view of aging. In conclusion, physicians and medical students used elderspeak when they explained a treatment to older patients. Participants with a more negative view of aging also unconsciously talked slower and made shorter utterances to a 40 year-old patient. [less ▲]

Background: Identifying older people affected by cancer who are more at risk of negative health outcomes is a major issue in health initiatives focusing on medical effectiveness. In this regard, psychological risk factors such as patients’ perception of their own aging and cancer could be used as indicators to improve customization of cancer care. We hypothesize that more negative self-perception of aging (SPA) and view of cancer could be linked to worse physical and mental health outcomes in cancer patients. Methods: 101 patients diagnosed with cancer (breast, gynecological, lung or hematological) were followed for one year. They were evaluated on four occasions (baseline, 3, 6 and 12 months after the baseline). Their SPA, view of cancer and health (physical and mental) were assessed at each time of evaluation. Results: Negative SPA and/or view of cancer at baseline are associated with negative evolution of patients’ physical and mental health. Moreover, when the evolution of SPA and cancer view were taken into account, these two stigmas are still linked with the evolution of mental health. In comparison, only a negative evolution of SPA was linked to worse physical health outcomes. Conclusions: Such results indicate that SPA and view of cancer could be used as markers of vulnerability in older people with cancer. [less ▲]

BACKGROUND: Different clinical trials show beneficial effects of physical training offered during and / or after breast cancer treatment. However, given the variety of side effects that may be encountered, physical training could be combined with psychological, relational and social guidance. This kind of multidisciplinary program has been little studied so far. AIM: To determine the benefits of a three-month multidisciplinary rehabilitation program among women after breast cancer treatment. DESIGN: Controlled no-randomized trial. SETTING: University for outcomes, University Hospital Center for interventions. POPULATION: Two hundred and nine outpatients who have been treated for a primary breast carcinoma. METHODS: Patients were divided into a control group (n=106) and an experimental group (n=103) which has benefited from a rehabilitation program of three months including physical training and psycho-educational sessions. The assessments, performed before and after the program, included functional assessments ("Sit and Reach Test", maximal incremental exercise test and "Six-Minute Walk Test"), body composition measurements (body mass index (BMI) and body fat percentage) and a questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30). RESULTS: After three months, flexibility, walking distance and all parameters measured during the maximal incremental exercise, except maximal heart rate, were significantly improved in the experimental group. The body fat percentage was significantly decreased and a significant improvement was observed for perceived health status (quality of life), functional role, emotional state, physical, cognitive and social functions and for most symptoms. In the control group, most of these improvements didn't appear and a significant increase in BMI and body fat percentage was observed. CONCLUSIONS: This trial identifies the benefits of a well detailed multidisciplinary rehabilitation program, including physical re-conditioning and psycho-educational sessions, with important improvements in functional capacity, body composition and the majority of functions and symptoms among women after breast cancer treatment. CLINICAL REHABILITATION IMPACT: Through its results, this study could contribute to the development of hospital quality standards for oncologic rehabilitation. Physiotherapists can efficiently propose this kind of multidisciplinary rehabilitation program. [less ▲]

Non-coding RNAs (ncRNA) represent at least 1/5 of the mammalian transcript amount, and about 90% of the genome length is actively transcribed. Many ncRNAs have been demonstrated to play a role in cancer. Among them, natural antisense transcripts (NAT) are RNA sequences which are complementary and overlapping to those of protein-coding transcripts (PCT). NATs were punctually described as regulating gene expression, and are expected to act more frequently in cis than other ncRNAs that commonly function in trans. In this work, 22 breast cancers expressing estrogen receptors and their paired healthy tissues were analyzed by strand-specific RNA sequencing. To highlight the potential role of NATs in gene regulations occurring in breast cancer, three different gene extraction methods were used: differential expression analysis of NATs between tumor and healthy tissues, differential correlation analysis of paired NAT/PCT between tumor and healthy tissues, and NAT/PCT read count ratio variation between tumor and healthy tissues. Each of these methods yielded lists of NAT/PCT pairs that were demonstrated to be enriched in survival-associated genes on an independent cohort (TCGA). This work allows to highlight NAT lists that display a strong potential to affect the expression of genes involved in the breast cancer pathology. [less ▲]

BACKGROUND: Triple-negative breast cancers (TNBC) are heterogeneous cancers with poor prognosis. We aimed to determine the clinical relevance of membrane type-4 matrix metalloproteinase (MT4-MMP), a membrane type matrix metalloproteinase that interacts with epidermal growth factor receptor (EGFR) overexpressed in >50% of TNBC. METHODS: We conducted a retrospective immunohistochemical analysis on human TNBC samples (n=81) and validated our findings in in vitro and in vivo assays. RESULTS: Membrane type-4 matrix metalloproteinase and EGFR are produced in 72.5% of TNBC samples, whereas those proteins are faintly produced by healthy tissues. Unexpectedly, tumour relapse after chemotherapy was reduced in samples highly positive for MT4-MMP. Mechanistically, this is ascribed to a higher sensitivity of MT4-MMP-producing cells to alkylating or intercalating chemotherapeutic agents, as assessed in vitro. In sharp contrast, MT4-MMP expression did not affect tumour cell sensitivity to paclitaxel that interferes with protease trafficking. Importantly, MT4-MMP expression sensitised cancer cells to erlotinib, a tyrosine kinase EGFR inhibitor. In a pre-clinical model, the growth of MT4-MMP overexpressing xenografts, but not of control ones, was reduced by epirubicin or erlotinib. The combination of suboptimal drug doses blocked drastically the growth of MT4-MMP-producing tumours. CONCLUSIONS: We demonstrate that MT4-MMP defines a sub-population of TNBC sensitive to a combination of DNA-targeting chemotherapeutic agents and anti-EGFR drugs.British Journal of Cancer advance online publication 14 February 2017; doi:10.1038/bjc.2017.23 www.bjcancer.com.

Objectives Older people may suffer from stigmas linked to cancer and aging. Although some studies suggested that a negative view of cancer may increase the level of depression, such an association has never been studied in the elderly population. Similarly, even though it is established that a negative self-perception of aging has deleterious consequences on mental and physical health in normal aging, the influence in pathological contexts, such as oncology, has not been studied. The main aim of this study is thus to analyze the effect of these two stigmas on the health of elderly oncology patients. Materials and Methods 101 patients suffering from a cancer (breast, gynecological, lung or hematological) were seen as soon as possible after their diagnosis. Their self-perception of age, cancer view and health (physical and mental) was assessed. Results Multiple regressions showed that patients with a more negative self-perception of aging and/or more negative cancer view reported poorer global health. We also observed that negative self-perception of aging was associated with worse physical and mental health, whereas negative cancer views were only linked to worse mental health. No interaction was observed between these two stigmas, suggesting that their action is independent. Conclusion Older patients with cancer face double stigmatization, due to negative self-perception of aging and cancer, and these stigmas have impacts on global and mental health. Self-perception of aging is also linked to physical health. Longitudinal studies will be necessary to analyze the direction of the association between this double stigmatization and health. [less ▲]

Breast cancer, with an increasing incidence, is the most frequently diagnosed cancer in women worldwide. The treatments proposed, generally a combination of surgery, radiotherapy, chemotherapy, endocrine therapy and / or targeted therapy, are constantly improving, allowing a reduction in the mortality rate, but they are still causing many side effects, not only early but also late, which leads us to consider the post-cancer period as a chronic condition. Side effects, reviewed in this commentary, may affect physical functions, psychological status, social situation, body composition, well-being and quality of life of the patient. In view of the extent of these areas in which side effects of breast cancer and of its treatments can be found, the supportive care offered at the end of treatment need to be multidisciplinary. Different supportive care interventions may be proposed to the patients such as psychological and behavioral interventions, complementary therapies, diet interventions, physical activity/rehabilitation or also physiotherapy interventions for example, all having shown some beneficial effects in the literature. The benefits of these supportive care interventions are thereby already established and they are described in this article, but others studies will be needed to clearly define indications and most optimal modalities of application to reduce side effects and improve quality of life of patients.

Objectif : Le cancer du sein ainsi que ses traitements sont à l'origine de nombreux effets secondaires indésirables, notamment sur la fonction physique. Cette étude a pour objectif de déterminer les bénéfices éventuels d’un programme de revalidation multidisciplinaire sur la santé physique des femmes ayant été traitées pour un cancer du sein et d'évaluer l'influence de certaines caractéristiques individuelles initiales sur la réponse du groupe expérimental au programme de revalidation. Matériel et méthodes : L'étude constitue un essai clinique contrôlé non-randomisé évaluant une population totale de 209 patientes, recrutées sur base du volontariat et réparties en deux groupes, soit un groupe contrôle (n = 106) et un groupe expérimental (n = 103). Ce dernier a bénéficié d’une revalidation de trois mois comprenant un entraînement physique supervisé à raison de trois séances par semaine et diverses sessions psycho-éducatives. Pour l'ensemble des participantes, des évaluations constituées d'une part de mesures physiques et fonctionnelles et d'autre part de mesures de composition corporelle ont été programmées à 0 et 3 mois. Celles-ci ont inclus un test de souplesse ("Sit and Reach"), un test d'effort maximal sur bicyclette ergométrique avec suivi cardio-respiratoire, un test de marche de six minutes et la mesure de l'indice de masse corporelle et du pourcentage de graisse corporelle. Afin d'affiner l'analyse, trois groupes ont également été constitués au sein du groupe expérimental à partir des caractéristiques individuelles de thérapie adjuvante (présence de chimiothérapie ou non), de chirurgie (mastectomie ou tumorectomie) et de délai de fin de traitement (délai ≤ 4 mois ou ≥ 8 mois). Résultats : Initialement, toutes les patientes présentent un état de déconditionnement physique, non influencé par le délai de fin de traitement ou par le type de chirurgie, mais bien influencé par la présence d'une chimiothérapie puisque la VO2max apparaît significativement plus faible dans ce cas. Au terme des trois mois, la souplesse (p < 0,0001), la consommation maximale d'oxygène (p < 0,0001), la puissance maximale aérobie (p < 0,0001) et la distance de marche en six minutes (p < 0,0001) s’améliorent significativement au sein du groupe expérimental. Au sein du groupe contrôle, aucune amélioration n'est constatée, excepté pour la distance de marche (p = 0,0031). Par ailleurs, une augmentation significative de l'indice de masse corporelle (p = 0,034) et du pourcentage de graisse corporelle (p = 0,034) est observée au sein du groupe contrôle alors que ce paramètre diminue significativement au sein du groupe expérimental (p = 0,037). Enfin, toutes les patientes du groupe expérimental présentent un même profil de progression quelles que soient leurs caractéristiques individuelles initiales. Conclusion : Cette étude démontre ainsi les effets bénéfiques, tant sur le plan physique que de la composition corporelle, d’une prise en charge multidisciplinaire chez des femmes ayant été traitées pour le cancer du sein.

BACKGROUND: This European phase 3b, expanded-access multicenter trial evaluated the safety of EVE plus EXE in a patient population similar to BOLERO-2. PATIENTS AND METHODS: Postmenopausal women aged (3)18 years with hormone receptor-positive, human epidermal growth factor-receptor-2-negative advanced breast cancer (ABC) recurring/progressing during/after prior non-steroidal aromatase inhibitors (NSAIs) were enrolled. Primary objective was safety of EVE plus EXE based on frequency of adverse events (AEs), and serious AEs (SAEs). Secondary objective was to evaluate AEs of grade 3/4 severity. RESULTS: Median treatment duration was 5.1 months (95% CI, 4.8-5.6) for EVE and 5.3 months (95% CI, 4.8-5.6) for EXE. Overall, 2131 patients were included in the analysis; 81.8% of patients experienced EVE- or EXE-related or EVE/EXE-related AEs (investigator assessed); 27.2% were of grade 3/4 severity. The most frequently reported non-hematologic AEs were (overall %, % EVE-related) stomatitis (52.8%; 50.8%) and asthenia (22.8%; 14.6%). The most frequently reported hematologic AE were (overall %, % EVE-related) anemia (14.4%; 8.1%) and thrombocytopenia (5.9%; 4.6%). AE-related treatment discontinuations were higher in elderly ((3)70 years) versus non-elderly patients (23.8% vs. 13.0%). The incidence of EVE-related AEs in both elderly and non-elderly patients appeared to be lower in first-line ABC versus later lines. The incidence of AEs (including stomatitis/pneumonitis) was independent of BMI status (post-hoc analysis). Overall, 8.5% of patients experienced at least one EVE-related SAE. Of the 121 on-treatment deaths (5.7%), 66 (3.1%) deaths were due to disease progression and 46 (2.2%) due to AEs; 4 deaths were suspected to be EVE-related. CONCLUSIONS: This is the largest ever reported safety dataset on a general patient population presenting ABC treated with EVE plus EXE and included a sizeable elderly subset. Although the patients were more heavily pretreated, the safety profile of EVE plus EXE in BALLET was consistent with BOLERO-2. CLINICAL TRIAL REGISTRATION: EudraCT Number: 2012-000073-23. [less ▲]

PURPOSE: Two recent phase III trials, BOLERO-1 and BOLERO-3 (Breast Cancer Trials of Oral Everolimus), evaluated the addition of everolimus to trastuzumab and chemotherapy in human epidermal growth factor receptor 2-overexpressing advanced breast cancer. The current analysis aimed to identify biomarkers to predict the clinical efficacy of everolimus treatment. METHODS: Archival tumor samples from patients in BOLERO-1 and BOLERO-3 were analyzed using next-generation sequencing, immunohistochemistry, and Sanger sequencing. RESULTS: Biomarker data were available for 549 patients. PIK3CA activating mutations and PTEN loss were reported in 30% and 16% of BOLERO-1 samples and in 32% and 12% of BOLERO-3 samples, respectively. PI3K pathway was hyperactive (PIK3CA mutations and/or PTEN loss and/or AKT1 mutation) in 47% of BOLERO-1 and 41% of BOLERO-3 samples. In both studies, differential progression-free survival (PFS) benefits of everolimus were consistently observed in patient subgroups defined by their PI3K pathway status. When analyzing combined data sets of both studies, everolimus was associated with a decreased hazard of progression in patients with PIK3CA mutations (hazard ratio [HR], 0.67; 95% CI, 0.45 to 1.00), PTEN loss (HR, 0.54; 95% CI, 0.31 to 0.96), or hyperactive PI3K pathway (HR, 0.67; 95% CI, 0.48 to 0.93). Patients with wild-type PIK3CA (HR, 1.10; 95% CI, 0.83 to 1.46), normal PTEN (HR, 1.00; 95% CI, 0.80 to 1.26), or normal PI3K pathway activity (HR, 1.19; 95% CI, 0.87 to 1.62) did not derive PFS benefit from everolimus. CONCLUSION: This analysis, although exploratory, suggests that patients with human epidermal growth factor receptor 2-positive advanced breast cancer having tumors with PIK3CA mutations, PTEN loss, or hyperactive PI3K pathway could derive PFS benefit from everolimus.

Les carcinomes de site primitif inconnu ou CaPI, forment un groupe d'entités pathologiques très hétérogènes de par leurs modes de révélation et leurs présentations cliniques. Le CaPI se définit par une tumeur épithéliale maligne, d'emblée métastatique, dont le site initial reste occulte au terme du bilan pré-thérapeutique exhaustif. Il représente 3 à 5% des tumeurs solides malignes de l'adulte. Son pronostic est sombre avec médiane de survie allant de 6 à 10 mois. La thérapeutique sera fonction de l'histologie tumorale, de la localisation métastatique et de la suspicion d'origine du primitif. En présence d'une néoplasie localisée, une prise en charge chirurgicale accompagnée ou non d'une radiothérapie sera proposée; en cas de dissémination métastatique multiple, une chimiothérapie systémique à base de sels de platine est recommandée. L'espoir réside dans l'analyse du profil moléculaire, afin de définir avec précision l'origine tumorale primitive et d'offrir la thérapeutique la mieux adaptée possible. [less ▲]
