Treatment of testicular cancer.
ard C Abstract Germ-cell tumours (GCTs) are the most common type of cancer in young men. Since the late 1970s, disseminated GCT have been a paradigm for curable metastatic cancer and metastatic GCTs are highly curable with cisplatin-based chemotherapy followed by surgical resection of residual masses. Patients' prognosis is currently assessed using the International Germ-Cell Consensus Classification (IGCCC) and used to adapt the burden of chemotherapy. Approximately 20% of patients still do not achieve cure after first-line cisplatin-based chemotherapy, and need salvage chemotherapy (high dose or standard dose ch...

Dependence receptors: life or death choices.
Abstract Whereas the classic dogma postulates that transmembrane receptors remain inactive at the plasma membrane unless bound by their specific ligand, it was suggested that some receptors may actually be active not only in the presence of their ligand, but also in their absence. In this latter case, the signaling downstream of these unbound receptors leads to apoptosis. These receptors were consequently named dependence receptors, as their cell expression renders the survival of the cell dependent on the presence in the cell environment of its respective ligand. This dual function - positive in the presence...

Morphological imaging for response assessment in metastatic bone disease.
Abstract Response assessment with morphological imaging in metastatic bone disease is difficult. X-Ray is useful only for long bones. CT is the best imaging modality for assessment of osteolysis and osteosclerosis. MRI is the gold standard for bone marrow morphological imaging. Morphological MR imaging using basic sequences, especially T1, provides confident evaluation of the behaviour of lesions under therapy. Radiotherapy and interventional radiology may induce cortical and bone marrow changes. PMID: 24197057 [PubMed - as supplied by publisher] (Source: Bulletin du Cancer)

The surgical treatment of metastases in the appendicular skeleton.
Abstract The orthopedic surgical treatment of metastases is very important in the treatment of osteophile cancers. The surgical option is always proposed after a multidisciplinary decision. The main risk of the metastases is the pathological fracture. This risk has to be evaluated and a preventive treatment can often be performed. The surgical options are multiple: such as preventive osteosynthesis, pathological fracture treatment, reconstruction with prosthesis, carcinological excision… The choice of the treatment is support on the life expectancy and the functional risk of the metastatic bone lesion. ...

Histology of bone metastases (technical aspects, searching for a primary).
Abstract The histologic diagnosis of bone metastasis is often easy, based on tumor morphologic features on routine examination. The determination of the primary tumor is facilitated by ancillary techniques such as histochemical stainings and immunohistochemistry: it is possible, in about 65% of cases, with clinical correlation. Additional immunohistochemistry or molecular analyses are becoming more useful in various tumors (breast, lung, melanoma…) to give targeted therapy. From a technical point of view, bone is characterised by its difficulty to be sampled (with frequent crushing artifacts) and the necess...

Multidisciplinary meetings dedicated to bone metastases: a historical perspective and rationale.
Abstract Bone metastases of solid tumors have a strong impact on patient's autonomy and vital outcome. Drugs specifically targeting bone remodeling as well as local treatment (radiotherapy, osteoplasty, surgery) make the management of bone metastasis a multidisciplinary process. Multidisciplinary teams (MDTs) dedicated to bone metastasis aim at providing the diagnosis of certainty, defining treatment indications and monitoring follow-up. The MDTs are the place for innovation in imaging and treatments of bone metastases. PMID: 24165281 [PubMed - as supplied by publisher] (Source: Bulletin du Cancer)

These markers include bone matrix synthesis and degradation products, or enzymes expressed by osteoblasts or osteoclasts. Thus, the use of these biochemical markers of bone metabolism is being evaluated in screening for development of bone metastases, in predicting risk of skeletal-related events and survival in patients with bone metastases, and in monitoring response to antiresorptive therapy.

Abstract Malignant tumor osteolysis is a frequent complication in many cancers. It can cause skeletal-related events with alteration of quality of life and survival. Bisphosphonates play an important role in the management of this malignant osteolysis, via an inhibition of osteoclast-mediated bone resorption, and a potential direct antitumor activity. Their use constitutes an important therapeutic advance in patients with bone metastases so as to reduce or delay the appearance of these skeletal events. They are also useful for the treatment of hypercalcemia, which could arise in these patients. Their interest as a...

Pathophysiology of bone metastases and new molecular targets involved in bone remodelling.
din P Abstract Bone metastases are common complications of cancers. These skeletal lesions are usually osteolytic (excess of bone destruction), osteosclerostic (excess of bone formation) or mixed. Metastatic cancer cells residing in the bone marrow alter the functions of bone-resorbing (osteoclasts) and bone-forming (osteoblasts) cells and hijack signals coming from the bone matrix. In this review, we first described cellular and molecular mechanisms that drive cancer cells to colonize the bone marrow. We next show how cancer cells alter bone remodelling to promote the formation of osteolytic or osteosclerotic les...

Abstract The management of bone metastases requires a multidisciplinary staff to include systemic and local treatments like radiotherapy, surgery or interventional radiology (IR). Patients are often fragile. Imaging allows safe guidance to create "mini-invasive" procedures under adequate anesthesia. Patients' selection is important. If the goal is pain relief, cementoplasty provides a very effective bone consolidation and pain control. Simple and low-risk, vertebroplasty is the technique of choice in case of lytic bone metastases with spinal fracture risk or after failure of analgesic radiotherapy. If th...

te; H Abstract The natural history of breast diseases has changed overtime and successive therapeutic strategies have been adapted accordingly. Recently, biological findings on geno- and phenotypic characteristics of tumor cells offer new basis for the development of treatments that target homogenous and various subtypes of breast cancer. Unfortunately, traditional clinical research tools are not in phase with rapid changes in both biological knowledge of the disease and new targeted agents. New methodological approaches are urgently needed to validate such changes and improvements in prognosis. PMID: 2400461...

Ruxolitinib prescription in myelofibrosis.
ay JO Abstract Ruxolitinib is a JAK/STAT inhibitor, which has demonstrated clinical benefits in patients with intermediate-2 and high-risk myelofibrosis. Moreover, first results of recent clinical trials show a trend to better overall survival with ruxolitinib, which allows to hope that we will soon be able to change the natural evolution of this poor outcome disease. With such results, ruxolitinib quickly obtained the Food and Drug Administration (FDA) approval in the United States of America. In France, ruxolitinib is now available, allowing its administration to symptomatic myelofibrosis patients. PMI...

Use of midazolam in hospitalized patients: analysis of medical practice.
Abstract To evaluate the prevalence and the characteristics of use of midazolam among hospitalized patients and to analyze physicians' representation of this medicine. We conducted a retrospective study between 1st May and 22nd May 2011 in Grenoble University Hospital in France. All patients receiving midazolam during the study period were included, excepted if the prescription was performed in intensive care units, operating rooms or in pediatric units. Physicians from the different units were asked about the characteristics of patients receiving midazolam and about their practice concerning the us...

Role of the surgical pathologist for tissue management in oncology.
Abstract Currently, the increasing number of ancillary methods to be performed from tumoral tissues in a pathology laboratory determines the necessity to have an optimal strategy for tissue management. The size of tissue samples dedicated for a pathological examination becomes smaller and smaller, as the diagnosis can be made with non or less invasive methods. However, the samples should also allow to provide the prognosis as well as to realise biological molecular testing in order to found a genomic alteration. Thus, it is critical to think about how to share and to pool the different expertises and abilities in ...

Small HER2-positive breast cancer: which prognosis and which adjuvant treatment?
no JP Abstract Incidence of centimetric or infracentimetric node negative (pT1a-b, N0) breast cancer is increasing due to screening procedures. Although considered as having an overall favorable prognosis, several retrospective studies have suggested a higher risk of relapse when HER2 is overexpressed. Since randomized studies evaluating trastuzumab in the adjuvant setting did not include T1a-bN0, there is no level I evidence supporting the administration of a trastuzumab-based post-operative chemotherapy in these cases. However, some recent retrospective data suggest a benefit for such a strategy and current guid...

Glutamate and malignant gliomas, from epilepsia to biological aggressiveness: therapeutic implications.
Abstract In this review article, we describe the unrecognized roles of glutamate and glutamate receptors in malignant glioma biology. The neurotransmitter glutamate released from malignant glioma cells in the extracellular matrix is responsible for seizure induction and at higher concentration neuronal cell death. This neuronal cell death will create vacated place for tumor growth. Glutamate also stimulates the growth and the migration of glial tumor cells by means of the activation of glutamate receptors on glioma cells in a paracrine and autocrine manner. The multitude of effects of glutamate in glioma biology s...

The importance of individual beliefs about cancer treatments for therapeutic decisions.
Abstract Interest for representations about cancer treatments and their side effects is increasing because their central role has been proved in how patients cope with illness and symptoms and how they react emotionally. Through a synthesis of the literature, this paper has two objectives: firstly, to clarify the current state of knowledge in this field, and secondly to point out the manner that bringing out these individual representations during oncological consultations contributes to preventing difficulties and treatment discontinuation and facilitates medical decision processing.
