RESUMO
OBJECTIVES: To explore the 10-year tolerability profile of glucocorticoids (GC) use in patients with early RA. METHODS: Analysis of 10-year outcome from the early arthritis ESPOIR cohort. Patients were stratified in two groups, without or with GC treatment at least once during their follow-up. The primary outcome was a composite of deaths, cardiovascular diseases (CVD), severe infections and fractures. The weighted Cox time-dependent analysis model was used with inverse probability of treatment weighting (IPTW) propensity score method. RESULTS: Among the 608 patients [480 women, mean age of 47.5 (12.1) years], 397 (65%) received low-dose GC [median 1.9 mg/day (IQR 0.6-4.2), mean cumulative prednisone dose 8468 mg (8376), mean duration 44.6 months (40.1)]. In univariate analysis, over 95 total events (10 deaths, 18 CVDs, 32 fractures and 35 severe infections), patients taking GC experienced more events (n = 71) than those without GC (n = 24) (P =0.035). Highest cumulative exposure of GC (≥8.4 g) was associated with highest risk of occurrence of the primary outcome (24.3%, P =0.007), CVDs (7.9%, P =0.001) and severe infections (9.9%, P =0.024). The risk of events over time was significantly associated with GC, age, hypertension and ESR. The risk associated with GC treatment increased between the first follow-up visit [hazard ratio (HR) at 1 year = 0.46, 95% CI: 0.23, 0.90] and 10 years (HR = 6.83, 95% CI: 2.29, 20.35). CONCLUSION: The 10-year analysis of this prospective early RA cohort supports a dose and time-dependent impact of low-dose GC treatment, with a long-term high risk of severe outcomes. TRIAL REGISTRATION: (ClinicalTrials.gov Identifier: NCT03666091).

OBJECTIVE: To determine which patients should benefit from the interposition of a well-vascularized flap between the neourethra and the penile skin and if it should be performed even in mild hypospadias. PATIENTS AND METHODS: A retrospective study on patients with a primary hypospadias repair was performed (2003-2017). Only patients undergoing urethroplasty based on the principle of a tubularization were selected to ensure comparable groups. Patients were assigned in two groups according to the use or not of a cover flap. Univariate analysis and adjusted logistic regression were used to evaluate the relation between postoperative complications, the severity of hypospadias, the use of flap and patients' characteristics. RESULTS: Three-hundred and seventy-six patients were included with anterior (59.3%), midshaft (27.4%) and posterior hypospadias (13.3%). The median follow-up was 54 months (24 months-17 years). The overall rate of fistula was 11.7% (n = 44). Comparing the outcome in children with flap (n = 217) to controls (n = 159) showed that the use of a flap reduces the rate of fistula (6.5 vs 18.9%, p < 0.001). Stratification of the study according to the phenotype reveals that the more severe the hypospadias, the more protective was the flap (OR = 2.6 for anterior, 5.5 for midpenile, 7.1 for posterior hypospadias). The flap remains nevertheless significantly effective whatever the phenotype (p < 0.05 for anterior, p = 0.01 for midpenile, p = 0.02 for posterior hypospadias). CONCLUSIONS: The more severe the hypospadias, the more effective is the cover flap to avoid fistula. It remains nevertheless suitable even in anterior hypospadias and the use of a cover flap should not be limited to the surgery of severe phenotypes.

PURPOSE: While familial forms of complex disorders/differences of sex development have been widely reported, data regarding isolated hypospadias are sparse and a family history is thought to be less frequent. We aimed to determine the frequency of hypospadias in families of boys with hypospadias, to establish whether these familial forms exhibit a particular phenotype and to evaluate the prevalence of genetic defects of the main candidate genes. MATERIALS AND METHODS: A total of 395 boys with hypospadias were prospectively screened for a family history with a standardized questionnaire, extensive clinical description, family tree and sequencing of AR, SF1, SRD5A2 and MAMLD1. RESULTS: Family history of hypospadias was more frequent than expected (88 patients, 22.3%). In 17 instances (19.3%) familial hypospadias cases were multiple. Familial hypospadias was related to the paternal side in 59.1% of cases, consisting of the father himself (30.7%) as well as paternal uncles and cousins. Premature birth, assisted reproductive techniques, other congenital abnormalities and growth retardation were not more frequent in familial hypospadias than in sporadic cases. The severity of phenotype was similar in both groups. The results of genetic analysis combined with previous data on androgen receptor sequencing revealed that familial cases more frequently tend to demonstrate genetic defects than sporadic cases (5.68% vs 1.63%, p = 0.048). CONCLUSIONS: Familial forms of hypospadias are far more frequent than previously reported. Even minor and isolated forms justify a full clinical investigation of the family history. Detecting these hereditary forms may help to determine the underlying genetic defects, and may improve followup and counseling of these patients.

OBJECTIVES: To evaluate the outcomes of hypospadias surgery according to age and to determine if some complications are age-related. PATIENTS AND METHODS: This retrospective study was based on 722 boys with hypospadias undergoing primary repair. A total of 501 boys underwent urethroplasty and were included in the study. Complications requiring an additional procedure (stenosis, fistula, dehiscence, relapse of curvature, urethrocele) were included in the analysis, as well as healing problems, infections, haematomas and detrusor-sphincter dyssynergy. Logistic regression analysis was performed. RESULTS: Hypospadias was anterior in 63.1%, mid-penile in 20.5%, posterior in 8.4% and scrotal in 7.9% of the boys. The median (range) age was 4 (1-16) years. The overall rates of re-intervention and complications were 22.8% and 36.2%, respectively. Age >2 years was a significant predictor of complications (P = 0.002, odds ratio 1.98 [95% confidence interval 1.26-3.13]). Some periods of time appeared to be associated with a specific complication: dyssynergy was more common between the ages of 24 and 36 months (12.5 vs 3.6%; P = 0.01) and healing problems were more common in boys aged >13 years (1.5 vs 28.5%; P = 0.06). CONCLUSION: Delayed surgery may be detrimental for patients. Factors related to age may influence the rate of complications. After the age of 2 years, urethral surgery may interfere with the normal toilet-training process. During puberty, endogenous testosterone may alter healing. Even if no specific data exist for severe hypospadias, it may be prudent to continue to advocate early surgery in patients with disorders of sex development.

In France, cervical screening is opportunistic and approximately 40% of women do not attend regular screening programs. The aim of this study was (1) to assess the prevalence of human papillomavirus (HPV) cervical infection and of cytological abnormalities in a population of young pregnant women with poor adherence to cervical cancer screening and (2) to evaluate the adherence to a screening strategy combining HPV testing and cytology during pregnancy. For this purpose, pregnant women benefited from a cervical smear associated with HPV DNA detection. High-risk HPV types were detected and identified using the HC2 assay and the INNO-LiPA HPV genotyping Extra assay. Two hundred forty-seven women (mean age 26.6 ± 5.1 years) were enrolled. Among them, 76.8% did not attend regular cervical cancer screening programs. High-risk HPV types were detected in 50 (20.2%) samples, HPV 16 being the most frequent (N = 12; 14.5%), with multiple HPV infection in 17 samples (27%). Nine (3.6%) abnormal cervical smears were diagnosed. Follow-up of women with abnormal cytology and/or infection with high-risk HPV was obtained in 29 cases (55.8%), showing 12 persistent high-risk HPV infections. Nine women had colposcopy with a final diagnosis of four normal cervixes, three cervical intraepithelial neoplasia grade 1 and two cervical intraepithelial neoplasia grade 2. Overall, women adherence to the free post-partum follow-up visit was 53.5%. This study suggests that a screening program combining HPV testing with cervical cytology during pregnancy may be one option to target young women with poor adhesion to regular cervical cancer screening.

BACKGROUND & AIMS: Significant progress has been made in the management of pancreatic ductal adenocarcinoma (PDAC) in recent years. In this population-based study, we aimed to compare incidence, therapeutic strategies, and survival outcomes of PDAC patients in France over a decade. METHODS: This study was performed using a nationwide French database. All patients receiving care for PDAC during years 2009, 2014 and 2018 were included. Treatment modalities and survival outcomes were analyzed. RESULTS: A total of 8143/8771/10494 patients were considered in 2009/2014/2018, respectively. Incidence increased mainly among patients aged >60 years. In localized PDAC, the proportion of patients receiving best supportive care (BSC) only decreased at 43.6/36.4/32.4 % and 27.8/29.1/34.3 % received chemo(radio)therapy alone. The rate of upfront surgery remained stable while 3/8/18 % of operated patients received neoadjuvant therapy. Median overall survival (OS) was 7.0/7.9/8.5 months in the overall population. Among treated patients, 1-year OS was 61.4/67.7/68.8 % and 30.3/36.3/38.8 % for localized and metastatic PDAC, respectively. CONCLUSIONS: This study confirms the rising incidence of PDAC. Improved outcomes were seen in localized PDAC, with a wider use of chemotherapy and neoadjuvant strategies, and in treated metastatic patients. A modest survival gain was seen overall, hindered by the still high rate of patients receiving BSC only.
RESUMO
BACKGROUND: The incidence and number of circulating tumor cells (CTCs) in the peripheral blood of colorectal cancer patients are lower than in other cancer types, which may point to a particular biology of colorectal cancer affecting CTC detection. METHODS: We detected CTCs in the peripheral and mesenteric blood of colorectal cancer patients by use of 2 independent technologies on the basis of different biological properties of colon cancer cells. Seventy-five patients diagnosed with localized (M0, n = 60) and metastatic (M1, n = 15) colorectal cancer were included. Peripheral and mesenteric blood samples were collected before tumor resection. We performed CTC enumeration with an EpCAM-independent enrichment method followed by the Epispot assay that detected only viable CK19-releasing CTCs. In parallel, we used the FDA-cleared EpCAM-dependent CellSearch® as the reference method. RESULTS: The enumeration of CK19-releasing cells by the CK19-Epispot assay revealed viable CTCs in 27 of 41 (65.9%) and 41 of 74 (55.4%) (P = 0.04) patients in mesenteric and peripheral blood, respectively, whereas CellSearch detected CTCs in 19 of 34 (55.9%) and 20 of 69 (29.0%) (P = 0.0046) patients. In mesenteric blood, medians of 4 (range 0-247) and 2.7 CTCs (range 0-286) were found with Epispot and CellSearch (P = 0.2), respectively, whereas in peripheral blood, Epispot and CellSearch detected a median of 1.2 (range 0-92) and 0 CTCs (range 0-147) (P = 0.002). CONCLUSIONS: A considerable portion of viable CTCs detectable by the Epispot assay are trapped in the liver as the first filter organ in CRC patients.

BACKGROUND: Detection of circulating tumor cells (CTCs) in the peripheral blood is a rapidly developing research field with clear clinical implications for the staging and monitoring of cancer patients. Current CTC assays, including the US Food and Drug Administration-cleared CellSearch® system, typically use markers [e.g., cytokeratins (CKs), the transmembrane protein EpCAM (epithelial cell adhesion molecule)] that are expressed on normal and malignant epithelial cells but not on the surrounding normal leukocytes. METHODS: We enrolled 53 patients with benign colon diseases (e.g., diverticulosis, benign polyps, Crohn disease, ulcerative rectocolitis, colonic endometriosis) and analyzed their peripheral blood with 2 previously validated CTC assays: the epithelial immunospot (EPISPOT) assay and the CellSearch system. The EPISPOT assay detects only viable, CK19-releasing CTCs that were enriched by depletion of CD45(+) leukocytes, whereas the CellSearch system detects CK-positive CTCs after positive EpCAM-based immunomagnetic enrichment. RESULTS: In patients with benign colon diseases, positive events that met the criteria for "tumor cells" were detected with both the CellSearch system (11.3%) and the CK19-EPISPOT assay (18.9%), whereas no positive events were detected in samples from healthy volunteers. Positive events were detected most frequently in patients with diverticulosis and Crohn disease. All positive events lacked expression of CD45, a common leukocyte antigen. CONCLUSIONS: These results indicate that patients with benign inflammatory colon diseases in particular can harbor viable circulating epithelial cells that are detectable with current CTC assays. This finding points to the need for further molecular characterization of circulating epithelial cells and has important implications for the use of CTC testing.

OBJECTIVE: Multimorbidity is frequent in rheumatoid arthritis (RA) and could interfere with the therapeutic response. The aim of this study was to evaluate multimorbidity in the French cohort of early arthritis, the ESPOIR cohort, and its possible impact on the therapeutic response. METHODS: We included patients fulfilling 2010 ACR/EULAR criteria for RA. An adapted MultiMorbidity Index (aMMI) was developed. Each patient was assigned scores of binary aMMI (0=no comorbidity, 1=at least 1 comorbidity) and counted and weighted aMMI. The primary endpoint was achievement of Clinical Disease Activity Index (CDAI) low disease activity after initiation of a first disease-modifying antirheumatic drug (DMARD) according to the aMMI. We collected data from the visit preceding the first DMARD initiation and the visit after at least 3 months of treatment. The impact of aMMI on therapeutic maintenance at 1, 3, 5 and 10 years was evaluated. RESULTS: Analyses involved 472 patients: 302 (64%) had at least 1 comorbidity. Overall, 45.3% and 44.7% with binary aMMI=0 or 1, respectively (non-significant), achieved CDAI low disease activity. Similar results were found with counted and weighted aMMI. Therapeutic maintenance was significantly better with binary aMMI=1 than binary aMMI=0 (OR at 10 years=14.0 [CI 95% 3.3-59.4]). Increased counted aMMI was associated with increased probability of still being on the first initiated DMARD at each time point. CONCLUSION: In the ESPOIR cohort, therapeutic response to a first DMARD was not affected by multimorbidity but therapeutic maintenance was better in multimorbid patients.

PURPOSE: To adapt the Moorong Self-Efficacy Scale (MSES) in the French language and determine its psychometric proprieties. MATERIALS AND METHODS: After a back-translation process, an expert committee was solicited to develop the French Self Efficacy Scale, thanks to a Delphi method, regarding theoretical framework and concepts explored. A total of 201 patients with SCI were included to explore internal consistency, internal and external structure validity assessed with the General Self-Efficacy scale, MOS Health Survey Short-Form, Hospital Anxiety and Depression Scale, Way of Coping Check-list, Perceived Stress Scale, Social Support Questionnaire, Self-Esteem questionnaire, and Satisfaction With Life Scale. The retest was performed 4 days later with a randomized version of the MSES-Fr. RESULTS: The 16 items are distributed in 3 different dimensions: Interpersonal Self-Efficacy (4 items), Instrumental Self-Efficacy (4 items) and Participation Self-Efficacy (6 items). The internal consistency was excellent (Cronbach α = .87). Results evidenced significant correlations with the MSES-Fr and other related psychological constructs (self-esteem, mood, quality of life). Reproducibility was good for the total score of the MSES-Fr (ICC = .74) and for the 3 dimensions of the scale. CONCLUSIONS: The MSES-Fr is a valid and reliable tool to assess self-efficacy in persons with spinal cord injury.Implications for rehabilitationThe Moorong Self-Efficacy Scale (MSES) is commonly used in persons with SCI for evaluating the level of perceived effectiveness in living with a disability.Validity and reliability studies of the MSES-Fr show good psychometrics properties in people with SCI.The French version of the MSES has been cross-culturally translated and is ready to be used clinically.

BACKGROUND: Poly(ADP-ribose) polymerase 1 inhibitor (PARPi) agents can improve progression-free survival of patients with breast cancer who carry a germline BRCA1 or BRCA2 pathogenic or likely pathogenic variant (gBRCA) in both the metastatic and adjuvant setting. Therefore, we need to reassess the frequency of gBRCA1 and gBRCA2 in order to redefine the criteria for women and tumor phenotype that should be tested. OBJECTIVE: We studied the relative distribution of gBRCA1 and gBRCA2 in unselected populations of women with breast cancer and in unaffected individuals. We also analyzed the proportion of estrogen receptor (ER)-positive (ER+) tumors in unselected breast cancer patients with gBRCA. DESIGN: We performed a meta-analysis of studies of unselected breast cancer that analyzed the relative contribution of gBRCA1 versus gBRCA2 among unselected breast cancer cases in gBRCA carriers. We then performed a meta-analysis of gBRCA carriage in unaffected individuals from genome-wide population studies, the gnomAD databank, and case-control studies. RESULTS: The BRCA2 gene was involved in 54% of breast cancer cases in unselected patients with gBRCA (n = 108,699) and 60% of unaffected individuals (n = 238,973) as compared with 38% of the largest gBRCA family cohort (n = 29,700). The meta-analysis showed that 1.66% (95% CI 1.08-2.54) and 1.71% (95% CI 1.33-2.2) of unselected breast cancer patients carried gBRCA1 and gBRCA2, respectively. In a population of unaffected individuals, the frequency of heterozygosity for gBRCA1 and gBRCA2 was estimated at 1/434 and 1/288, respectively. Nearly 0.5% of unaffected individuals in the studied populations carried a gBRCA. Carriage of a gBRCA was 2.5% for patients with ER+ tumors (95% CI 1.5-4.1) and 5.7% (95% CI 5.1-6.2) for those with ER- tumors. Overall, 58% of breast tumors occurring in women carrying a gBRCA were ER+ (n = 86,870). CONCLUSIONS: This meta-analysis showed that gBRCA2 carriage is predominant in unselected breast cancer patients and unaffected individuals. ER+ tumors among women with gBRCA-related breast cancer are predominant and have been underestimated. Because PARPi agents improve progression-free survival with ER+ gBRCA breast cancer in most clinical trials, breast cancer should be considered, regardless of ER status, for BRCA1/2 screening for therapeutic purposes.
RESUMO
PURPOSE: The metabolic changes associated with cachexia - sarcopenia syndrome might down-regulate antitumor immunity. We hypothesized that this syndrome reduces efficiency of immune checkpoint inhibitors (ICPI) in non-small cell lung cancer (NSCLC). METHODS: The records of 142 consecutive NSCLC patients receiving first- or second-line anti-Programmed cell death protein 1) ICPI were reviewed. Response evaluation according to Response Evaluation Criteria in Solid Tumors 1.1 was performed at the eighth week of immunotherapy. Pretreatment cachexia was defined as a body-weight loss of 5% or more in the previous 6 months. Sarcopenia was estimated with the third lumbar skeletal muscle mass index (mSMI) and was evaluated before immunotherapy and at the eighth week. A decrease by 5% or more of the mSMI was considered as an evolving sarcopenia. The endpoints were disease control rate (DCR), progression-free (PFS) and overall survival (OS).Logistic regression model and Cox model took into account others covariables known to influence ICPI efficiency, particularly Programmed Death -Ligand 1 tumor cell score, Eastern Cooperative Oncology Group performance status and common somatic mutational status. RESULTS: In multivariate analysis, cachexia - sarcopenia syndrome reduced the probability of achieving a disease control and were associated with a shorter survival. Patients without cachexia had a better probability to achieve disease control in comparison with those who did not experience cachexia (59.9 % and 41.1 %, respectively; odds ratio 95 % (confidence interval [95 %CI]): 2.60 (1.03-6.58)). Patients with cachexia had a shorter OS when compared with those without cachexia (hazard ratios [HR] (95 %CI): 6.26 (2.23-17.57)). Patients with an evolving sarcopenia had a shorter PFS and OS, with HR (95 %CI): 2.45 (1.09-5.53) and 3.87 (1.60-9.34) respectively. CONCLUSION: Cachexia - sarcopenia syndrome negatively influences patients' outcome during anti-PD-1 ICPI therapy.

INTRODUCTION: This study aimed at generating a new simplified prognostic score (SPS) using common clinical and biological variables to discriminate a limited number of subgroups of patients with SCLC differing by their overall survival (OS). METHODS: The SPS was developed exploring the Montpellier University Hospital retrospective database of 401 patients over a 16-year period. All patients had received etoposide - platinum-based chemotherapy as first-line treatment. The SPS development took into account significant determinants of OS in the Cox model, weighted by their regression ß coefficients. Validation of the consequent SPS has been done separately in a combined population of 213 patients accrued from two different published trials (NCT03059667 and NCT00930891). RESULTS: The significant independent determinants of OS included the following: (1) American Joint Committee on Cancer TNM stage IV (hazard ratio [HR]: 2.52; 95% confidence interval [CI]: 1.91-3.33); (2) Eastern Cooperative Oncology Group performance status greater than 1 (HR: 2.27; 95% CI: 1.79-2.87); (3) the presence of liver metastases (HR: 1.66; 95% CI: 1.29-2.15); and (4) neutrophil-to-lymphocyte ratio greater than 4 (HR: 1.39; 95% CI: 1.11-1.92). The SPS generated with these four variables, segregated three groups (good, intermediate, and poor prognosis) with respective median OS of 26.9 months (95% CI: 20.1-38.9), 11.5 months (95% CI: 9.8-13.0), and 6.8 months (95% CI: 5.8-8.3; log-rank p < 10-4). Harrell's C statistic estimate was 0.68 ± 0.012, suggesting goodness of calibration. In the validation cohort, the SPS segregated the aforementioned three subgroups in a nearly similar manner, with respective median OS: 27.2, 12.3, and 8.6 months (log-rank p < 10-3; Harrell's C statistic: 0.58 ± 0.02). CONCLUSIONS: The SPS is easy to calculate in real-life practice and efficiently discriminates three populations with different prognoses. This study deserves further validation of this score in patients with SCLC receiving immunochemotherapy.
RESUMO
INTRODUCTION: There is currently a lack of evidence for the relative effectiveness of partial resection (PR) and total resection (TR) before managing abdominal aortic graft infection (AGI). Most authorities agree that TR is mandatory for intracavitary AGI in patients with favorable conditions but there is an increasing number of patients with severe comorbidities for whom this approach is not suitable, resulting in a prohibitive mortality rate. The purpose of this study was to determine the most appropriate indication for TR or PR. EVIDENCE ACQUISITION: A meta-analysis was conducted on the rates of early/late mortality, amputations and reinfection. A meta-regression was performed with eight variables: patient age, male prevalence, presence of virulent or nonvirulent organisms, urgency, omentoplasty and follow-up. EVIDENCE SYNTHESIS: Twenty-one studies and 1052 patients were included. For TR and PR, the rates of early mortality and reinfection were 16.8% and 10.5%, 11% and 27%, respectively. For TR urgency and male gender were associated with increased rate of early mortality and male gender, PDF and virulent organisms were associated with increased risk of reinfection. For PR no statistical correlation was analyzable except for PDF with increased risk of reinfection. CONCLUSIONS: Early mortality rates are higher for TR and reinfection rates are higher for PR. For TR early mortality increases in urgent cases and it is suggested that alternative option must be discussed, reinfection decreases in the presence of nonvirulent organisms and TR seems optimal. For TR and PR reinfection increases in presence of PDF and alternative technique may be more appropriate.

INTRODUCTION: To evaluate if torsion of an otherwise healthy ovary (THO) has a different prognosis than torsion with an underlying ovarian mass (TUOM) in children. MATERIAL AND METHODS: Children with an ovarian torsion who were treated in our department from 1997 to 2016 were studied retrospectively. Patients with prenatal ovarian torsion and isolated oviduct torsion were excluded. Trophicity of the ovary was assessed by ultrasonography at the end of follow-up. RESULTS: Fifty-four girls were included. Twenty-seven presented a TUOM; the others had a THO. Beside the deleterious effect of late surgical management, another prognostic factor was identified. THO was more prone to an ovarian hypotrophy or atrophy than TUOM (nâ¯=â¯20 vs nâ¯=â¯5, pâ¯<â¯0.01). This was confirmed by logistic regression analysis (ORâ¯=â¯5.08, pâ¯=â¯0.01). To explain this finding, we further compared TUOM and THO. The diagnosis of TUOM was more frequently suspected on US at the first visit (pâ¯=â¯0.005). TUOM also occurred more often after puberty (>12â¯years, 52.9% vs 11.1%, pâ¯<â¯0.001) than THO. CONCLUSION: THO is more frequently associated with an ovarian atrophy or hypotrophy than TUOM. A less obvious diagnosis at US and the early occurrence of THO before puberty with a less favorable hormonal climate may explain this finding. LEVEL OF EVIDENCE: III.

INTRODUCTION: Several non-comparative phase II studies have evaluated metronomic oral vinorelbine (MOV) in metastatic non-small cell lung cancer (NSCLC) but the small size of each study limits their conclusions. PURPOSE: To perform an individual patient-data metaanalysis of studies evaluating MOV in metastatic NSCLC in order to measure survival and safety of treatment with this regimen. METHODS: Studies were selected if (1) administration of oral vinorelbine thrice a week; (2) fixed daily dose comprised between 30 and 50 mg, and; (3) being published before October 4th 2018. Database encompassed 8 variables characterizing disease and demography, 3 informing therapy, and 12 describing survival and toxicity. RESULTS: Nine studies encompassing 418 patients fulfilled the selection criteria, 80% of them having frailty characteristics. Median overall survival (OS) was 8.7 months (95%CI: 7.6-9.5). OSrates at 6 months, one year and at two years after starting vinorelbine were 64%, 30.3% and 8.9%, respectively. In the Cox model, Eastern Cooperative Oncology Group (ECOG) performance status (PS) = 2, and anemia of any grade were significant determinants of shorter OS. Median progression-free survival(PFS) was 4.2 months (95%CI: 3.9-5). At 6 months and at one-year, PFS rates were 35% and 11.9% respectively. In the Cox model stratified for the variable "study", PS = 2and stage IV were significant determinants of shorter PFS. No toxicity was reported for 40% of patients, and 66 (15.8%) patients experienced a grade 3-4 toxicity. The most frequent toxicity was anemia of any grade (35.8%) that was higher with the 50 mg dosage. CONCLUSION: MOV is an active and well-tolerated chemotherapy in metastatic NSCLC and is a manageable therapy in frail patients.

OBJECTIVE: To confirm the advantage of in situ reconstruction (ISR) over extra-anatomic reconstruction (EAR) for aortic graft infection and determine the most appropriate conduit including autogenous veins, cryopreserved allografts, and synthetic prosthesis (standard, rifampicin of silver polyesters). METHODS: A meta-analysis was conducted with rate of mortality, graft occlusion, amputation, and reinfection. A meta-regression was performed with 4 factors: patients' age, presence of prosthetic-duodenal fistula (PDF), virulent organisms, or nonvirulent organisms. RESULTS: In situ reconstruction over EAR seems to favor all events. For the 5 conduits used for ISR, according to operative mortality, age of the patients looks to have a positive correlation only for silver polyester and no conduit present any advantage in the presence of PDF. Reinfection seems to be not significantly different for the 5 conduits, and only autogenous veins appear to have a positive correlation with infecting organisms. CONCLUSION: In situ reconstruction may be considered as first-line treatment. Our results suggest that silver polyesters appear to be most appropriate for older patients, and in order to limit reinfection, autogenous veins are probably the most suitable conduit.

Multipotent mesenchymal stromal cells (MSC) display a high potential for the development of novel treatment strategies for cartilage repair. However, the pathways involved in their differentiation to functional non hypertrophic chondrocytes remain largely unknown, despite the work on embryologic development and the identification of key growth factors including TGFbeta, Hh, Wnt and FGF. In this study, we asked if we could identify specific biological networks common to the growth factors used (TGFbeta3 or BMP-2). To address this question, we used DNA microarrays and performed large-scale expression profiling of MSC at different time points during their chondrogenic differentiation. By comparing these data with those obtained during the differentiation of MSC into osteoblasts and adipocytes, we identified 318 genes specific for chondrogenesis and developed a new algorithm to classify the genes according to their kinetic profile. We distributed the selected genes in five classes according to their kinetic of expression. We could reconstruct three phases characterized by functional pathways. The first phase corresponds to cell attachment and apoptosis induction; the second phase is characterized by a proliferation/differentiation step, and the third phase is characterized by a differentiation/hypertrophy pathway. Indeed, these data propose new pathways to understand the complexity of MSC differentiation to chondrocytes.
