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.

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 ▲]

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.

Epithelial-mesenchymal transition (EMT) is prominent in circulating tumor cells (CTC), but how it influences metastatic spread in this setting is obscure. Insofar as blood provides a specific microenvironment for tumor cells, we explored a potential link between EMT and coagulation that may provide EMT-positive CTC with enhanced colonizing properties. Here we report that EMT induces tissue factor (TF), a major cell-associated initiator of coagulation and related pro-coagulant properties in the blood. TF blockade by antibody or shRNA diminished the pro-coagulant activity of EMT-positive cells, confirming a functional role for TF in these processes. Silencing the EMT transcription factor ZEB1 inhibited both EMT-associated TF expression and coagulant activity, further strengthening the link between EMT and coagulation. Accordingly, EMT-positive cells exhibited a higher persistance/survival in the lungs of mice colonized after intravenous injection, a feature diminished by TF or ZEB1 silencing. In tumor cells with limited metastatic capability, enforcing expression of the EMT transcription factor Snail increased TF, coagulant properties and early metastasis. Clinically, we identified a subpopulation of CTC expressing vimentin and TF in the blood of metastatic breast cancer patients consistent with our observations. Overall, our findings define a novel EMT-TF regulatory axis which triggers local activation of coagulation pathways to support metastatic colonization of EMT-positive CTC. [less ▲]
