Abstract
BACKGROUND Patients diagnosed with therapy-related myeloid neoplasms (TRMN) with concomitant active neoplastic disorder (CAND) are usually proposed for best supportive care (BSC). We evaluated the feasibility of using 5-azacytidine (AZA) in this setting. METHODS All patients referred to Gustave Roussy between 2010 and 2015 for TRMN diagnosis (less than 30% blast) and eligible for AZA treatment were included. Patients with CAND proposed for BSC were also described. Patient's outcomes were analyzed based on the presence or not of a CAND. RESULTS Fifty-two patients with TRMN were analyzed, including 19 patients with CAND (14 eligible for AZA) and 33 without CAND eligible for AZA. The 5 patients with CAND ineligible for AZA had a worst performance status (p=0.016) at diagnosis and a shorter overall survival (OS) (0.62 months). Baseline characteristics of patients eligible for AZA were similar in the 2 groups except a trend for best performance status in patients with CAND (p=0.06). Overall response rate (71.4% vs 60.3%), transfusion independence (50.0% vs 45.5%) and OS (12.7 months vs 10.8 months) were similar between patients with and without CAND respectively (p=ns). CONCLUSION Here we report the feasibility and efficacy of AZA for selected patients with TRMN and a CAND.

Abstract
Pharmaceutical analyses of chemotherapy prescriptions by hospital pharmacists are activities codified by regulation and rules (bon usage). The involvement of the pharmacists in clinical pharmacy activities in the oncology setting is not clearly identified, justifying the development of a mapping of these activities from a questionnaire addressed to the professionals. One hundred and seven centers have participated to this study at the national level (overall participation rate of 32.4%). More than 95% of them used a computerized ordering system and three quarter of them submit the introduction of new compounds to an analysis by the drug therapeutic committee. Prescription analysis allowed detecting around 2% of errors from the current prescription. Clinical pharmacist participates to tumor boards of onco-hematology (RCP) at a level of 46% for senior pharmacist and 42% for junior pharmacist. This involvement in the RCP allowed anticipating protocol's modification and temporary used authorization. Ninety-two percent of the senior pharmacists estimate that they highlight the risk of no reimbursement for prescription out of the guideline during RCP, resulting to a modification of the prescription for 40% of them. This level of intervention is lower with respectively 64% and 10% for the juniors. This study underlines the expert value of the clinical pharmacist dedicated to oncology setting in pre and post analysis prescriptions. It could be targeted by a prospective analysis of both clinical and pharmacoeconomics impact of these interventions.

Abstract
Oxidative stress plays a role in the regulation of cancer cell metastasis which involves cell invasion and adhesion that could be supported by ADAM proteins through the activities of their metalloprotease and disintegrin domains. We hypothesized that oxidative stress could act through the induction of ADAM9 protein in some cancer cells. Indeed, Western blot analysis for ADAM9 performed on A549 cells exposed to H(2) O(2) reveals a dose-dependent induction of two proteins (80 and 68 kDa) correlated with a sharp increase of the ADAM protease activity measured in supernatant while the activity measured on the cell layer was slightly affected. The 80kDa protein corresponds to the mature form of ADAM9. Immunoprecipitation analysis performed on concentrated supernatants revealed that the 68 kDa protein is a secreted form of ADAM9. When exposed to H(2) O(2) , A549 cells cocultured with confluent endothelial vascular cells resulted in a 5.5 fold (p < 0.001) increase in the number of adherent cells. Similarly, matrigel assay revealed a 3.25 fold (p < 0.01) increase in the number of invasive cells. The suppression of ADAM9 expression by specific small interfering RNA reduced oxidative stress-induced invasiveness and adhesiveness. These functions could be mediated by an interaction between ADAM9 and β1 integrin because each of them were inhibited when the experiment is performed in presence of mAbs targeting ADAM9 ectodomain or β1-integrin. These results emphasize the importance of oxidative stress in the regulation of cancer cell metastasis and suggest that ADAM9 and its secreted isoform can be important determinants in the ability of cancer cells to disseminate.

Abstract
19585 Background: Chemotherapy (CT) is the treatment of choice for most metastatic cancers. Frequent functional impairment and comorbidities in the elderly increase the risk of chemotherapy-related acute complications. The applicability of clinical trials data to the elderly population is exposed to multiple bias. Informations extracted from non-selected treated patients (pts) may be useful. Methods: A serie of consecutive elderly cancer pts (>73 years) treated over 3 years in the oncology outpatient unit, and receiving CT were included for analysis and assessed using prechemotherapy evaluation of cancer in the elderly (including performance status, comorbidities, glomerular filtration rate, liver tests, hemogram, nutritional status, inflammation tests). Relationship between preCT evaluation and acute complications, unscheduled hospitalisation, mortality were investigated by univariate analyses. Comparison between planned and realised dose- intensity of CT protocols could be extracted for the CT prescription software. Results: 108 pts with a median age of 78 years (73- 89; 44% over 80) were identified. Characteristics included performance status (PS) ≥ 2 (44%), chronic renal insufficiency (47%) ; ≥2 comorbidities (75%). Primary tumour was urologic (31%), gastro-intestinal (29%), mammary and gynaecologic (20%); pulmonary (16%) or other (4%). Disease stage was metastatic for 82% of pts. Most CT regimens contained a platinum derivative (55%), gemcitabine (25%), 5-FU (20%), taxanes (17%), vinorelbine (15%). Transfusion requirements were higher in PS≥2 pts (p<0.0001). Febrile neutropenia correlated with PS, lymphocytopenia and PINI =(CRP×AAG)/(albumin×pre-albumin)>10 (p<0. 05). Unscheduled hospitalisation correlated with PS, lymphocytopenia, PINI, more than 2 co-morbidities, more than 4 co-medications. Oxaliplatin- and paclitaxel-containing CT protocols were associated with significant reduction of dose-intensity because of reduced number of cycles due to neurosensory toxicity (p=0.01). Conclusions: Lymphocytopenia, PS, and PINI were the most relevant prognosticators of short-term CT outcome. Elderly pts characteristics are associated with higher risk of acute toxicity and increased sensitivity to neurosensory cumulative toxicity. No significant financial relationships to disclose.

Abstract
PURPOSE Cyclosporine administration is very effective in the case of immunological diseases of the cornea, conjunctive or uvea. Moreover, it is widely used in the case of high-risk rejection corneal transplantation. We present a preparation of cyclosporine 2% eye drops. METHODS Cyclosporine 2% eye drops are prepared following a particular formulation including one part commercially available cyclosporine oral solution (Sandimmun) diluted in four parts of sterile castor oil. Manufacturing procedures maintain the sterile state of the preparation with a laminar airflow hood placed in a particulate controlled room, with pharmacists, technicians and clerical personnel wearing sterile clothes. Physical and chemical monitoring during and after manufacture for each batch guarantees the process and minimizes the risk of batch rejection. Chemical analysis of cyclosporine is conducted using a validated stability-indicating high-performance liquid chromatographic assay (reverse-phase). Blood dosages taken after the first administration at the 24th hour (after administration of the 6th drop) check for systemic integration. RESULTS Cyclosporine 2% eye drops are fairly stable: 12 months after manufacturing, concentrations result in levels not statistically different from concentrations measured the day of preparation. After a daily regimen of six drops in the eye, cyclosporine 2% eye drops have a very low systemic bioavailability, because the blood concentrations only reach the detection limit of the fluorescence polarization immunoassay used for cyclosporine drug monitoring. This explains the absence of systemic toxicity. CONCLUSION Cyclosporine 2% eye drops can be available in the hospital pharmacy. The eye drops are stable at room temperature and can be delivered up to 12 months after manufacture. No local adverse effects have been noted, probably in relation with the very low concentration of ethanol in the ocular preparation.

Abstract
Chondrocytes cultivated in monolayer rapidly divide and lose their morphological and biochemical characteristics, whereas they maintain their phenotype for long periods of time when they are cultivated in alginate beads. Because cartilage has a low cellularity and is difficult to obtain in large quantities, the number of available cells often becomes a limiting factor in studies of chondrocyte biology. Therefore, we explored the possibility of restoring the differentiated properties of chondrocytes by cultivating them in alginate beads after two multiplication passages in monolayer. This resulted in the reexpression of the two main markers of differentiated chondrocytes: Aggrecan and type II collagen gene expression was strongly reinduced from day 4 after alginate inclusion and paralleled protein expression. However, 2 weeks were necessary for total suppression of type I and III collagen synthesis, indicators of a modulated phenotype. Interleukin-1beta, a cytokine that is present in the synovial fluid of rheumatoid arthritis patients, induces many metabolic changes on the chondrocyte biology. Compared with cells in primary culture, the production of nitric oxide and 92-kDa gelatinase in response to interleukin-1beta was impaired in cells at passage 2 in monolayer but was fully recovered after their culture in alginate beads for 2 weeks. This suggests that the effects of interleukin-1beta on cartilage depend on the differentiation state of chondrocytes. This makes the culture in alginate beads a relevant model for the study of chondrocyte biology in the presence of interleukin-1beta and other mediators of cartilage destruction in rheumatoid arthritis and osteoarthrosis.

Abstract
Among the various directions explored in order to have a large number of differentiated articular chondrocytes easily available, the restoration of the differentiated properties after cell multiplication in monolayer has been proposed. It has been clearly shown that the synthesis of cartilage proteoglycans and type II collagen synthesis is coincident with the presence of a faint microfibrillar architecture but is absent in chondrocytes showing well-defined actin cables. Staurosporin, mainly described as a protein kinase C inhibitor, has also been shown to rapidly induce the disruption of the actin microfilaments. The purpose of this paper was to investigate whether properties of differentiated chondrocytes were reinitiated upon staurosporin treatment of serially passaged chondrocytes. Results showed, after staurosporine treatment of cells at Passage two for 5 d, complete suppression of type I and type III collagen synthesis and induction of type II collagen synthesis and of Alcian blue stainable matrix. Additionally, we showed that staurosporin restored metabolic responses that chondrocytes in primary culture exhibit upon interleukin-1 beta treatment (decrease of Alcian blue- positive cells, induction of expression of the 92 kDa gelatinase, nitric oxide production). We conclude that staurosporin is a potent redifferentiating agent of articular chondrocytes that have been subcultured up to Passage two for multiplication. Taking into account that the cellularity of cartilage is very low, staurosporine-treated chondrocytes could be useful as an alternative cellular model to evaluate pharmacotoxicological effects of drugs.
