Eribulin gained its approval in March 2011 for the treatment of patients with locally advanced or metastatic breast cancer (MBC) whose disease has progressed despite anthracycline and taxane-containing regimens. This study retrospectively assessed the efficacy, safety and cost of this treatment for all patients with MBC treated by eribulin in Franche-Comté. Ninety-four patients received eribulin between July 2006 and October 2013. The median age was 62 years (35-83). Median overall survival was 10.3 months [95% CI: 7.6 to 17.9]. Median progression-free-survival was 3.8 months [95% CI: 2.9 to 5.0]. Clinical benefit was obtained in 55% evaluable patients [95% CI: 43.1 to 66.9] by RECIST criteria. Most common grade 3-4 adverse events (AEs) were neutropenia (38%), asthenia (10%) and peripheral neuropathy (7%). Median cost of the treatment was 9767 € per patient (6344-17,517). This analysis found similar results to the EMBRACE study despite less selected population. A medico-economic evaluation cost-utility type would assess the effectiveness of this strategy compared to standard treatments., (Copyright © 2015 Société Française du Cancer.

The PEEK-Optima(®), composite mixture of polyetheretherketon and inert materials, is used in orthopedics, spinal surgery and cranio-facial surgery. It could be used in dental implantology because of its biological and mechanical properties. The results of an experimental and finite element study made on basal implant prototypes, on basal implantology show that PEEK, contrary to titanium, has a compound structure that allows to optimize the distribution of masticatory forces around the implant. These results should be confirmed by a clinical study according to research regulation., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Despite that greater knowledge of prostate cancer biology has led to the isolation of many new and promising targets, treatment of metastatic prostate cancer is still challenging. New agents targeting these molecules are currently under development in large randomized phase III trials, to improve overall survival and the quality of life of patients with metastatic castrate-resistant prostatic cancer (CRPC). Cytotoxic chemotherapy (docetaxel-based chemotherapy) demonstrated clinical benefit on overall survival, but could be improved. Drugs targeting directly or not the androgen receptor such as abiraterone or new specific peripheral anti-androgens (MDV3100) are very promising. Bone targeted therapies (endothelin1 receptor A inhibitor, RANK ligant, metabolic irradiation) are also very promising and are in development in large phase III trials. Antiangiogenic therapies could also be effective in CRPC. Autologous vaccin against prostatic acid phosphatase seems to prolong overall survival and other vaccin and immunotherapy strategies are in development (anti-CTLA4 antibody). A recent analogue of thalidomide, probably more efficient, lenalidomide is also in development.
