Discordances between hormone receptors and HER2 status in primary and metastatic breast cancer have been reported by several studies. In this context, systematic biopsies could be clinically relevant in breast cancer to confirm the biological characteristics of a suspicious lesion. In this article, illustrated by 2 case reports and based on a recent review on this topic, we discuss the clinical significance of receptor discordances and possible diagnosis of a secondary primary tumor. The role of these biopsies for the identification of new therapeutic targets is also envisaged as well as underlying mechanisms for receptors' modification like tumoral heterogeneity, clonal selection and technical artifacts.

PURPOSE: The main objective of this study was to describe geriatric recommendations based on a geriatric assessment (GA) and to evaluate the implementation of these recommendations. PATIENTS AND METHODS: A two-step approach of screening followed by a GA was implemented in nine hospitals in Belgium. Patients >/=70years were included at diagnosis or at disease progression/relapse. Concrete geriatric recommendations were systematically documented and reported to the treating physicians and consisted of referrals to professional health care workers. Patient charts were reviewed after one month to verify which geriatric recommendations have been performed. RESULTS: From August 2011 to July 2012, 1550 patients were included for analysis. The median age was 77 (range: 70-97) and 57.0% were female. A solid tumour was diagnosed in 91.4% and a haematological malignancy in 8.6%. Geriatric screening with the G8 identified 63.6% of the patients for GA (n=986). A median of two geriatric recommendations (range: 1-6) were given for 76.2% (95%CI: 73.4-78.8) of the evaluable patients (n=710). A median of one geriatric recommendation (range: 1-5) was performed in 52.1% (95%CI: 48.4-55.8) of the evaluable patients (n=689). In general, 460 or 35.3% (95%CI: 32.8-38.0) of all the geriatric recommendations were performed. Geriatric recommendations most frequently consisted of referrals to the dietician (60.4%), social worker (40.3%), and psychologist (28.9%). CONCLUSION: This implementation study provides insight into GA-based recommendations/interventions in daily oncology practice. Geriatric recommendations were given in about three-fourths of patients. About one-third of all geriatric recommendations were performed in approximately half of these patients. [less ▲]

BACKGROUND: Healthcare resource utilization in breast cancer varies by disease characteristics and treatment choices. However, lack of clarity in guidelines can result in varied interpretation and heterogeneous treatment management and costs. In Europe, the extent of this variability is unclear. Therefore, evaluation of chemotherapy use and costs versus hormone therapy across Europe is needed. METHODS: This retrospective chart review (N = 355) examined primarily direct costs for chemotherapy versus hormone therapy in postmenopausal women with hormone-receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) advanced breast cancer across 5 European countries (France, Germany, The Netherlands, Belgium, and Sweden). RESULTS: Total direct costs across the first 3 treatment lines were approximately euro10 000 to euro14 000 lower for an additional line of hormone therapy-based treatment versus switching to chemotherapy-based treatment. Direct cost difference between chemotherapy-based and hormone therapy-based regimens was approximately euro1900 to euro2500 per month. Chemotherapy-based regimens were associated with increased resource utilization (managing side effects; concomitant targeted therapy use; and increased frequencies of hospitalizations, provider visits, and monitoring tests). The proportion of patients taking sick leave doubled after switching from hormone therapy to chemotherapy. CONCLUSIONS: These results suggest chemotherapy is associated with increased direct costs and potentially with increased indirect costs (lower productivity of working patients) versus hormone therapy in HR+, HER2- advanced breast cancer.

BACKGROUND: The BRCA1 gene plays a key role in triple negative breast cancers (TNBCs), in which its expression can be lost by multiple mechanisms: germinal mutation followed by deletion of the second allele; negative regulation by promoter methylation; or miRNA-mediated silencing. This study aimed to establish a correlation among the BRCA1-related molecular parameters, tumor characteristics and clinical follow-up of patients to find new prognostic factors. METHODS: BRCA1 protein and mRNA expression was quantified in situ in the TNBCs of 69 patients. BRCA1 promoter methylation status was checked, as well as cytokeratin 5/6 expression. Maintenance of expressed BRCA1 protein interaction with BARD1 was quantified, as a marker of BRCA1 functionality, and the tumor expression profiles of 27 microRNAs were determined. RESULTS: miR-548c-5p was emphasized as a new independent prognostic factor in TNBC. A combination of the tumoral expression of miR-548c and three other known prognostic parameters (tumor size, lymph node invasion and CK 5/6 expression status) allowed for relapse prediction by logistic regression with an area under the curve (AUC) = 0.96. BRCA1 mRNA and protein in situ expression, as well as the amount of BRCA1 ligated to BARD1 in the tumor, lacked any associations with patient outcomes, likely due to high intratumoral heterogeneity, and thus could not be used for clinical purposes. CONCLUSIONS: In situ BRCA1-related expression parameters could be used for clinical purposes at the time of diagnosis. In contrast, miR-548c-5p showed a promising potential as a prognostic factor in TNBC. [less ▲]

Solid tumors comprise cancer cells and different supportive stromal cells, including mesenchymal stem cells (MSCs), which have recently been shown to enhance tumor growth and metastasis. We provide new mechanistic insights into how bone marrow (BM)-derived MSCs co-injected with Lewis lung carcinoma cells promote tumor growth and metastasis in mice. The proinvasive effect of BM-MSCs exerted on tumor cells relies on an unprecedented juxtacrine action of BM-MSC, leading to the trans-shedding of amphiregulin (AREG) from the tumor cell membrane by tumor necrosis factor-α-converting enzyme carried by the BM-MSC plasma membrane. The released soluble AREG activates cancer cells and promotes their invasiveness. This novel concept is supported by the exploitation of different 2D and 3D culture systems and by pharmacological approaches using a tumor necrosis factor-α-converting enzyme inhibitor and AREG-blocking antibodies. Altogether, we here assign a new function to BM-MSC in tumor progression and establish an uncovered link between AREG and BM-MSC. [less ▲]

Basal cell carcinoma is the most frequent skin cancer. Even though metastases are exceptional, these cancers may be locally highly aggressive. The Hedgehog signaling pathway plays a significant role in the pathogenesis of basal cell carcinoma. Vismodegib is a selective inhibitor of this pathway and may be administered orally. Its main indication is locally advanced basal cell carcinoma, when other therapeutic options have failed or are contra-indicated. Vismodegib can also be used as prophylactic therapy in the Gorlin syndrome or basal cell nevomatosis. Its principal adverse effects are muscle spasms, alopecia and altered taste. They are frequent, but often moderate in intensity; they sometimes restrict continuation of treatment. Two clinical cases are presented, relating the efficacity and tolerance of this new therapeutic option. [less ▲]

The interaction between tumor cells and their microenvironment is an essential aspect of tumor development. Therefore, understanding how this microenvironment communicates with tumor cells is crucial for the development of new anti-cancer therapies. MicroRNAs (miRNAs) are small non-coding RNAs that inhibit gene expression. They are secreted into the extracellular medium in vesicles called exosomes, which allow communication between cells via the transfer of their cargo. Consequently, we hypothesized that circulating endothelial miRNAs could be transferred to tumor cells and modify their phenotype. Using exogenous miRNA, we demonstrated that endothelial cells can transfer miRNA to tumor cells via exosomes. Using miRNA profiling, we identified miR-503, which exhibited downregulated levels in exosomes released from endothelial cells cultured under tumoral conditions. The modulation of miR-503 in breast cancer cells altered their proliferative and invasive capacities. We then identified two targets of miR-503, CCND2 and CCND3. Moreover, we measured increased plasmatic miR-503 in breast cancer patients after neoadjuvant chemotherapy, which could be partly due to increased miRNA secretion by endothelial cells. Taken together, our data are the first to reveal the involvement of the endothelium in the modulation of tumor development via the secretion of circulating miR-503 in response to chemotherapy treatment.

The goal of adjuvant anti-cancer therapies is cure with limited or no side effects, in particular long-term side effects with negative impact on quality of life. In the palliative setting disease control, quality of life and overall survival are important end points. Partly due to improvements in treatment, the population of cancer survivors is large and growing. However, anti-cancer drug-related cardiotoxicity (ADRC) is the leading cause of treatment-associated mortality in cancer survivors. It is one of the most common post-treatment problems among 5- to 10-year survivors of adult cancer. This is particularly true for breast cancer, the most common cancer in women. The EACVI/HFA COT registry is designed for comprehensive data collection and evaluation of the current European practice in terms of diagnosis and management of ADRC in breast cancer patients. The COT registry will be carried out in two continuing phases, the pilot study phase involving 13 countries followed by the long-term registry in which all the 56 ESC countries will be invited to participate. With the COT registry, several critical information will be obtained: on predisposing factors for the development of ADRC, the rate of subclinical LV dysfunction and its transition to overt heart failure, the clinical impact and outcome of ADRC.

En conséquence, médecins généralistes, urgentistes, hématologues et oncologues se trouvent régulièrement confrontés à un effet secondaire sévère des traitements cytotoxiques, le neutropénie fébrile (NF). La NF est une complication gravissime de la chimiothérapie, car elle peut être rapidement mortelle et provoque un arrêt temporaire, voire définitif, des traitements. Dans cet article, nous résumons les dernières recommandations quant à la prise en charge thérapeutique des patients présentant une NF sous traitements anti-cancéreux. [less ▲]

Les nouvelles technologies permettent une analyse détaillée des anomalies génomiques au niveau des cellules cancéreuses. Malheureusement, nous n'avons pas encore compris comment utiliser au mieux ces données au bénéfice du patient. La majorité des modifications du génome sont des évènements relativement rares compliquant le développement de nouveaux médicaments dans le cadre d'une médecine de précision. De plus, les tumeurs présentent une grande hétérogénéité temporelle et spatiale dont il faudra tenir compte lors de ce développement.

The goal of this study was to compare the efficacy and toxicity of chemotherapy to exemestane plus everolimus (EXE/EVE) through a network meta-analysis (NMA) of randomized controlled trials. NMA methods extend standard pairwise meta-analysis to allow simultaneous comparison of multiple treatments while maintaining randomization of individual studies. The method enables "direct" evidence (i.e., evidence from studies directly comparing two interventions) and "indirect" evidence (i.e., evidence from studies that do not compare the two interventions directly) to be pooled under the assumption of evidence consistency. We used NMA to evaluate progression-free survival (PFS) and time to progression (TTP) curves in 34 studies, and response rate (RR) and the hazard ratios (HRs) of the PFS/TTP in 36 studies. A number needed to treat (NNT) analysis was also performed as well as descriptive comparison of reported toxicities. The NMA for PFS/TTP curves and for HR shows EXE/EVE is more efficacious than capecitabine plus sunitinib, CMF, megestrol acetate and tamoxifen, with an average of related-PFS/TTP difference ranging from about 10 months for capecitabine plus sunitinib to more than 6 months for tamoxifen. The NMA for overall RR shows that EXE/EVE provides a better RR than bevacizumab plus capecitabine, capecitabine, capecitabine plus sorafenib, capecitabine plus sunitinib, CMF, gemcitabine plus epirubicin plus paclitaxel, EVE plus tamoxifen, EXE, FEC, megestrol acetate, mitoxantrone, and tamoxifen. Finally, the NMA for NNT shows that EXE/EVE is more beneficial as compared to BMF, capecitabine, capecitabine plus sunitinib, CMF, FEC, megestrol acetate, mitoxantrone, and tamoxifen. The combination of EXE/EVE as first- or second-line therapy for ER+ve/HER2-ve metastatic breast cancer is more efficacious than several chemotherapy regimens that were reported in the literature. Toxicities also favored EXE/EVE in most instances. [less ▲]
