Abstract
BACKGROUND Diffuse low-grade gliomas (DLGGs) are rare and incurable tumors. Whereas maximal safe, functional-based surgical resection is the first-line treatment, the timing and choice of further treatments (chemotherapy, radiation therapy, or combined treatments) remain controversial. METHODS An online survey on the management of DLGG patients was sent to 28 expert centers from the European Low-Grade Glioma Network (ELGGN) in May 2015. It contained 40 specific questions addressing the modalities of use of chemotherapy in these patients. RESULTS The survey demonstrated a significant heterogeneity in practice regarding the initial management of DLGG patients and the use of chemotherapy. Interestingly, radiation therapy combined with the procarbazine, CCNU (lomustine), and vincristine regimen has not imposed itself as the gold-standard treatment after surgery, despite the results of the Radiation Therapy Oncology Group 9802 study. Temozolomide is largely used as first-line treatment after surgical resection for high-risk DLGG patients, or at progression. CONCLUSIONS The heterogeneity in the management of patients with DLGG demonstrates that many questions regarding the postoperative strategy and the use of chemotherapy remain unanswered. Our survey reveals a high recruitment potential within the ELGGN for retrospective or prospective studies to generate new data regarding these issues.

Abstract
e15544 Background: Platinum resistant-refractory ovarian cancer (PRROC) patients have a poor outcome; single-agent therapy is still the gold standard, with overall response rate lesser than 20% and progression-free-survival is not higher than 4 months. Methods: We tested safety and activity of a two-drugs-regimen containing NPLED and cyclophosphamide in a phase II open label study. From October 2007 to October 2011 thirty-two patients with platinum-resistant/refractory disease were enrolled. Enrolled patients were pretreated with a median number of 2 lines of chemotherapy, ranging from 1 to 5. NPLED and cyclophosphamide were administered at the dose of 60 mg. and 600 mg p.s.m. respectively. Results: Patients received a median number of three cycles of chemotherapy. A total of 145 cycles were administered: as G3 toxicities we registered emesis (6%), diaorrhea (3%), asthenia, and alopecia. No grade 4 adverse events occurred. Among the 30 patients evaluable for response we observed 5 (17%) partial responses and 10 (33%) stable diseases. The median progression-free-survival was 13 weeks and the median survival was 46 weeks. Conclusions: These results are similar to other data reported in literature. In conclusion we may affirm that the association of NPLED and cyclophosphamide is active and safe when administered in PRROC, but it don’t modify the prognosis of this subset of patients.

Abstract
To be practical, any method for improving bull semen must yield a large quantity of motile spermatozoa. Some separation methods based on physical properties, e.g. filtration, chromatography, centrifugation, washing and pooling, have been reported as satisfactory, but generally are not repeatable. Nevertheless, filtration methods appear to allow the attainment of an acceptable number of spermatozoa, thus allowing such a technique to be introduced in the production of standard bovine semen doses for artificial insemination. The aim of this work was to evaluate systematically the relative effects of three filtration matrixes (silica oxide, glass beads or Sephadexätrade mark) on the improvement of whole ejaculate quality. Analysis of the type of matrix and the volume and height of the filtration column was performed. The only characteristic of the columns that appears to influence ejaculate quality after filtering is the matrix volume. While all matrixes produced improvement of semen quality, SephadexTM was better than the other matrixes tested. An explanation for the mechanism of column filtration is proposed.
