Contexte et problématique : La société des savoirs constitue un changement de paradigme sur la forme et sur le fond. La science ouverte (SO) est un mouvement mondial qui vise à rendre accessible les produits de la recherche et qui s’accélère avec les potentialités technologiques. Elle s’appuie sur un certain nombre de principes : accès et diffusion large et sans entrave, partage et retombée des produits de la recherche avec la société civile. Contenu et analyse : La SO comporte un accès libre et gratuit aux articles, un accès aux données sources, une analyse des données, la mise à disposition de pré-prints, l’évaluation ouverte. Dans ce contexte, la francophonie, par l’hétérogénéité de ses situations et son homogénéité linguistique, apparaît comme un terrain privilégié d’observation et d’expérimentation. Le Groupe de réflexion et d’information en science ouverte francophone (GRISOF), qui œuvre à l’amélioration de la recherche francophone dans la science médicale et en santé, propose, à partir de ses acquis, quelques clés pratiques pour le chercheur clinicien, le chercheur en biomédical et en santé publique, oriente sa réflexion vers l’évaluation et intensifie sa feuille de route sur la formation. Si l’anglais est la langue prédominante, le traitement automatique du langage (TAL) constitue une opportunité technologique. L’accès libre aux articles donne une opportunité aux travaux en français de mieux se faire connaître, de même que la traduction numérisée permet d’accéder aux articles d’autres langues. Conclusion : L’accès libre aux articles permet d’améliorer la profondeur et l’étendue des connaissances des étudiants. Il constitue une composante essentielle des apprentissages de recherche. Faire participer les étudiants à la publication ouverte de leurs propres travaux est un moyen de les sensibiliser aux pratiques scientifiques ouvertes.

Background: The link between organizing pneumonia (OP) and gastroesophageal reflux disease (GERD) is not well known. There is little evidence in the literature to establish a causal link between GERD and OP. Objectives: The aim of the study was to assess the hypothesis that OP is more severe when it is associated with GERD and that it leads to more frequent relapses. Methods: In a retrospective study on 44 patients suffering from OP, we compared the clinical, radiological and histological characteristics of 2 groups, 1 composed of patients with GERD (n = 20) and the other of patients without GERD (n = 24). Results: The GERD group was distinguished by a higher number of patients with migratory alveolar opacities on chest radiography and thoracic computerized tomography (14/20 vs. 9/24; p = 0.03 and 18/20 vs. 13/24; p = 0.01), greater hypoxemia [60 (42-80) vs. 70 (51-112) mm Hg; p = 0.03], greater bronchoalveolar lavage cellularity [0.255 (0.1-1.8) vs. 0.150 (0.05-0.4) g/l; p = 0.035] and more frequent relapses (14/20 vs. 9/24; p = 0.03). Conclusions: OP associated with GERD is more severe and results in more frequent relapses. Microinhalation of gastric secretions might induce lung inflammation leading to OP and relapse. We suggest that typical symptoms of GERD such as pyrosis should be investigated in OP.

The aim of this study was to evaluate on 1 day the prevalence of malnutrition in different types of cancer and the use of nutrition support in patients with cancer.A 1-day prevalence survey was carried out in 154 French hospital wards. Malnutrition was defined as a body mass index (BMI)18.5 in patients75 years old or21 in patients ≥75 years old and/or body weight loss10% since disease onset. Oral food intake was measured using a visual analog scale.Nutrition status was collected for 1903 patients (1109 men and 794 women, 59.3 ± 13.2 years). Cancer was local in 25%, regional in 31%, and metastatic in 44% of patients. Performance status was 0 or 1 in 49.8%, 2 in 23.7%, 3 or 4 in 19.6% and not available in 6.5% of patients. Overall, 39% of patients were malnourished. The prevalence of malnutrition by disease site was as follows: head and neck, 48.9%; leukemia/lymphoma, 34.0%; lung, 45.3%; colon/rectum, 39.3%; esophagus and/or stomach, 60.2%; pancreas, 66.7%; breast, 20.5%; ovaries/uterus, 44.8%; and prostate, 13.9%. Regional cancer (odds ratio, 1.96; 95% confidence interval, 1.42-2.70), metastatic cancer (2.97; 2.14-4.12), previous chemotherapy (1.41; 1.05-1.89), and previous radiotherapy (1.53; 1.21-1.92) were associated with malnutrition. Only 28.4% of non-malnourished patients and 57.6% of malnourished patients received nutrition support. In all, 55% of patients stated that they were eating less than before the cancer, while 41.4% of patients stated that they had received nutrition counseling.The prevalence of malnutrition is high in patients with cancer, and systematic screening for and treatment of malnutrition is necessary.

Resume Le depistage par scanner thoracique est une question d’actualite. Des etudes pilotes realisees au Japon, aux USA et en France, ont montre la grande sensibilite du scanner pour decouvrir des nodules pulmonaires. Par contre, la specificite est mauvaise, induisant de renouveler le scanner a distance ou de pratiquer des examens complementaires. Seules, des etudes randomisees permettront de demontrer que le scanner peut avoir un impact sur la mortalite specifique par cancer bronchique.

Summary Background Bronchogenic carcinoma (BC) is a worldwide health public problem with a parallel but delayed development to smoking. The prognosis of BC in young patients is poorly known mainly because of few studies that have looked at this group of patients. The hypothesis of our study is that ‘young’ patients with BC have a better prognosis than others. Methods We conducted a retrospective epidemiologic study of all patients aged 45 and under (n = 73) followed for BC between 2002 and 2007 in two hospitals in the central region in France, compared with patients over 45 years random (n = 73). We evaluated the clinical characteristics (sex, smoking habits, WHO status, clinical presentation, histology, TNM stage), the management and prognosis of these patients. Results The median survival of patients aged 45 and under was 13.4 months against 8.9 months for patients over 45 years. In multivariate analysis, age is not an independent prognostic factor (P = 0.41) in contrast to the WHO status (P = 0.002) and initial TNM stage (P Conclusion In our study, the better prognosis of the “young” patient group is not directly related to age but in good condition and lower TNM stage of these patients.

Resume Contexte Le colloque singulier entre le medecin referent et le patient en cancerologie integre, depuis leur mise en place par le Plan cancer, les elements decisionnels issus de la reunion de concertation pluridisciplinaire (RCP). Methodes Afin d’evaluer l’impact de la RCP sur la relation medecin-patient, une etude a ete menee au centre hospitalier universitaire (CHU) de Tours entre janvier 2005 et mai 2006. Trois outils methodologiques complementaires ont ete elabores : un questionnaire patients, une etude de dossiers portant sur la mise en application des decisions de la RCP et un questionnaire aux medecins referents participant aux RCP. Resultats Cent quarante-cinq questionnaires ont ete recueillis aupres de patients dont le dossier a ete discute en RCP, 40 questionnaires recueillis aupres des medecins participant aux reunions et une analyse de 324 dossiers a ete realisee. Quatre-vingt pour cent des patients reconnaissaient l’avis de la RCP comme rassurant, 73 % exprimaient que le plus important pour eux etait la relation avec le medecin referent et 96 % avaient une totale ou grande confiance dans le medecin referent. La confiance semblait liee a la qualite de la communication, a la liberte de dialogue et a la competence reconnue du medecin en particulier dans le choix du traitement. L’etude des dossiers a montre que dans 91 % des cas, l’avis de la RCP etait applique et que, dans 69 % des cas, c’est le medecin referent qui delivrait l’information au patient apres la RCP. Du point de vue des medecins, 33/40 disaient que la RCP ne modifiait pas leur relation avec le patient. On note que 35/40 exprimaient que la consultation apres RCP facilitait la presentation de la decision et 37/40 que la decision appliquee etait toujours ou souvent en accord avec l’avis de la RCP. Conclusion La RCP apparait le plus souvent ne pas modifier le colloque singulier. De par la confiance que le patient lui accorde, le role du medecin referent est essentiel dans l’integration de l’avis collegial de la RCP et il s’agit de veiller au risque d’un desengagement de celui-ci dans le choix decisionnel.

Lung cancer is the leading cause of cancer-related deaths in industrialized countries and non small cell lung cancer (NSCLC) accounts for 85% of all lung cancers. Cisplatin doublet based chemotherapy, which is the recommended regimen in first line therapy in advanced or metastatic NSCLC, improves survival but in low proportion. Monoclonal antibodies (mAbs) are a novel promising therapeutic class used with great results in inflammatory diseases such as rheumatoid arthritis. Antibodies are natural proteins with modular structure, specific pharmacodynamics and pharmacokinetics and possibly produced against any antigens, thus giving them several advantages over small drug therapeutics. In solid tumors, therapeutic mAbs improved progression free survival (PFS) and overall survival (OS) of patients with breast and colon cancers and had considerably changed the treatment in clinical practice. In NSCLC, bevacizumab, an anti-VEGF mAb, and cetuximab, an anti-EGFR mAb, are the most studied antibodies. Bevacizumab acts on angiognenesis and improved PFS of non squamous NSCLC but in low proportion as shown in two large phase III trials. It was approved by European Medicines Agency (EMEA) and Food and Drug administration (FDA) as a first line therapy in combination with cisplatin doublet chemotherapy. Cetuximab slightly enhanced OS but did not improve PFS in two large phase III trials. These results added to high adverse effect lead to cetuximab refusal by EMEA and FDA in NSCLC. At first glance, the results of mAbs in NSCLC are somewhat disappointing, in contrast to the benefits obtained with mAb treatments in other solid tumors. However, many other mAbs directed against novel targets, such as IGF1-R or CTLA-4, and new mAbs targeting VEGFR and EGFR pathways with different pharmacodymamical and pharmacokinetic properties are under evaluation and may change our vision of taking care of patients with NSCLC. In conclusion, it seems that mAbs therapy in NSCLC clearly marks the start of a new era in NSCLC treatment, with promises in improving patient survival and quality of life.

We investigated the biodistribution, pharmacokinetics, safety profile, and feasibility of aerosolized gemcitabine (GCB) in patients with lung carcinoma.Eleven patients with carcinoma localized in the lungs were studied in a dose escalation study of aerosolized GCB administered 1 day/week for 9 consecutive weeks. Safety data, scintigraphic assessment of the delivered dose and pharmacokinetic monitoring were analyzed. Patients were treated with doses of between 1 mg/kg and 4 mg/kg (dose in the nebulizer), using a new inhaler device (Aeroneb Pro with an Idehaler Chamber).The total dose of GCB delivered to the patient's lung was 42±16% of the initial amount of dose in the nebulizer. Safety data showed no hematologic toxicity, nephrotoxicity or neurotoxicity. At 4 mg/kg, one patient experienced grade 4 pulmonary toxicity (bronchospasm), which was the dose-limiting toxicity. Grade 2 and 3 toxic effects included fatigue, vomiting, dyspnea, and cough. Overall response: minor response in one patient, stable disease in four patients, progressive disease in four patients. Pharmacokinetic data showed very low plasma GCB levels. Maximal plasma concentration was observed at the end of nebulization. Aerosolized gemcitabin was safe, with minimal toxicity, for patients with lung carcinoma.

Introduction Vinflunine (Javlor) has shown significant antitumour activity in advanced non-small cell lung cancer (NSCLC). We propose to define the recommended dose of vinflunine in combination with gemcitabine for treatment of advanced NSCLC in chemonaive patients. Methods A phase I and pharmacokinetic study was conducted to determine the maximum tolerated dose and to establish the recommended dose of vinflunine (VFL) administered on day 1 every 21 days combined with gemcitabine given on days 1 and 8 every 3 weeks. Results Nineteen patients were included in this study. Three patients experienced a dose limiting toxicity, with constipation in one patient, hypertension in one patient, and constipation and febrile neutropenia in one patient. The combination of VFL 320 mg/m 2 and gemcitabine 1250 mg/m 2 was defined as the maximum tolerated dose. The recommended dose was established at the dose of VFL 320 mg/m 2 combined with gemcitabine 1000 mg/m 2 . Neither VFL nor gemcitabine seemed to be influencing the pharmacokinetics of each other. All patients were evaluable for tumor response. Seven presented a partial response and eight experienced a stable disease. Conclusions The combination of VFL 320 mg/m 2 administered on day 1 combined with gemcitabine 1000 mg/m 2 given on days 1 and 8 every 3 weeks is established as the RD and was shown to be active in these chemonaive NSCLC patients.

Multidisciplinary meeting (MDM) in oncology has been institutionalised in France by the Cancer Plan. This study aims to determine the place of MDM in the decision process. From November 2004 to July 2005, we observed 29 meetings at the Tours Hospital and 324 case presentations, 80 in orthopaedics, 151 in gastroenterology and 93 in chest medicine. Forty physicians attending the meetings answered a questionnaire exploring their opinions on MDM and the collegial decision. We found that MDM is mostly the place for technical discussions and that patients' wishes are rarely addressed. The different medical specialities are well represented but we observed that only physicians attend MDM. Decisions for straightforward cases are rapidly validated. For more complex clinical situations (25 to 40% of case presentations), the multidisciplinary approach allows to adapt guidelines or to choose alternative treatments. All the physicians interviewed express that MDM legitimates the medical decision. It occurs that they disagree with the RCP decision. We discuss how MDM impacts on the medical decision as well as the shift from the individual decision to the collective one, particularly in term of responsibility.

Background: Tissue factor (TF), the main initiator of blood coagulation, is also a signaling protein that regulates cancer progression. TF synthesis was recently shown to be affected by tumor suppressor genes (TSGs) in tumor cell lines. We therefore studied TF gene (F3) expression and the status of genes coding for tumor protein p53 (TP53), phosphatase and tensin homolog (PTEN), and serine/threonine kinase 11 (STK11) in non–small cell lung cancer (NSCLC). Heparanase (HPSE) gene expression was also measured because this endo-β-D-glucuronidase was recently shown to enhance TF gene expression. Methods: TF and heparanase mRNA expression was measured by real-time PCR in 53 NSCLC tumors. Exons 5–8 of TP53 were sequenced from genomic DNA. Mutations of PTEN and STK11 were screened by multiplex ligation-dependent probe amplification. Results: TF mRNA levels were significantly higher in T3–T4 tumors (P = 0.04) and in stages III–IV of NSCLC (P = 0.03). Mutations of TP53, STK11, and PTEN were identified in 20 (37.7%), 21 (39%), and 20 (37.7%) of tumors, respectively. TF expression was higher in mutated TP53 (TP53Mut) (P = 0.02) and PTENMut (P = 0.03) samples. Moreover, TF mRNA increased from 2700 copies (no mutation) to 11 6415 when 3 TSG were mutated. Heparanase gene expression did not differ according to TF gene (F3) expression or TSG mutation. The median survival time was shorter in patients with tumor TF mRNA levels above median values (relative risk 2.2; P = 0.03, multivariate analysis) and when TP53 was mutated (relative risk 1.8; P = 0.02). Conclusions: These results provide clear evidence that combined oncogene events affecting TSG dramatically increase TF gene expression in lung tumors. Moreover, this study suggests that TF gene expression could be used as a prognostic marker in NSCLC. .

Despite an increasing interest in the use of inhalation for local delivery of molecules for respiratory diseases and systemic disorders, methods to deliver therapy through airways has received little attention for lung cancer treatment. However, inhalation of anticancer drugs is an attractive alternative route to systemic administration which results in limited concentration of the medication in the lungs, and triggers whole-body toxicity. In this study, we investigated the feasibility of nebulization for therapeutic antibodies, a new class of fully-approved anticancer drugs in oncology medicine. Cetuximab, a chimeric IgG1 targeting the epidermal growth factor receptor (EGFR), was nebulized using three types of delivery devices: a jet nebulizer PARI LC+®, a mesh nebulizer AeronebPro® and an ultrasonic nebulizer SYST’AM® LS290. Aerosol size distribution was measured using a cascade impactor and aerosol droplets were observed under optical microscopy. The immunological and pharmacological properties of cetuximab were evaluated following nebulization using A431 cells. The aerosol particle clouds generated with the three nebulizers displayed similar aerodynamical characteristics, but the IgG formed aggregates in liquid phase following nebulization with both the jet and ultrasonic devices. Flow cytometry analyses and assays of EGFR-phosphorylation and cell growth inhibitions on A431 demonstrated that both the mesh and the jet nebulizers preserved the binding affinity to EGFR and the inhibitory activities of cetuximab. Altogether, our results indicate that cetuximab resists the physical constraints of nebulization. Thus, airway delivery represents a promising alternative to systemic administration for local delivery of therapeutic antibodies in lung cancer treatment.

Resume Le cancer bronchique est la premiere cause de deces par cancer, dans le monde, avec un taux de survie a 5 ans, de 15 %. Toutefois, des progres ont ete realises ces dix dernieres annees, ameliorant la mediane de survie et la survie a 2 et 5 ans. Ces progres sont dus a l’utilisation de doublets a base de cisplatine avec de nouveaux agents cytotoxiques et plus recemment, a l’apparition des therapies ciblees. Dans le cancer bronchique non a petites cellules au stade metastatique, la chimiotherapie prolonge la survie et ameliore la qualite de vie chez les patients en bon etat general. Les doublets a base de platine sont maintenant le standard de traitement et des combinaisons sans cisplatine constituent des alternatives. La combinaison de la chimiotherapie avec les inhibiteurs de l’angiogenese a demontre son impact sur la duree de survie.

Resume Etats des connaissances Les instances scientifiques preconisent une attitude minimaliste dans la surveillance des cancers bronchiques operes (examen clinique et radiographie thoracique). D’apres une enquete, 70 % des pneumologues francais ont opte pour l’usage du scanner et souvent de l’endoscopie. Les donnees de la litterature sont disparates, souvent issues d’etudes retrospectives. Methodes Le cancer bronchique est un bon modele pour realiser un essai de surveillance postoperatoire. Les recidives surviennent frequemment dans une aire facile a surveiller, peuvent etre decouvertes alors qu’elles sont encore asymptomatiques, sont parfois accessibles a un traitement curatif, ont un siege identique a celui des 2 e cancers observes. L’Intergroupe Francophone de Cancerologie Thoracique (IFCT) a debute un essai comparant une surveillance legere (examen clinique, radiographie thoracique) a une surveillance lourde (scanner, fibroscopie). La surveillance est realisee tous les 6 mois pendant 2 ans puis annuellement jusqu’a 5 ans. Resultats attendus L’objectif principal est de savoir si une surveillance lourde permet d’augmenter la survie des patients. Toute aussi importante est la question inverse. Si une surveillance couteuse et penible n’interfere pas sur les chances de guerison, il est fondamental d’en tirer les consequences sur les pratiques.

Resume Les tumeurs germinales du mediastin (teratomes, seminomes et tumeurs germinales malignes non seminomateuses) constituent un groupe heterogene de tumeurs malignes et benignes. Le traitement standard des tumeurs germinales malignes non seminomateuses localisees au mediastin repose sur quatre cycles de chimiotherapie suivis de la resection de la masse residuelle. Les seminomes mediastinaux localises et de petite taille sont traites par chirurgie suivie d’une radiotherapie. Dans les formes avancees, le traitement debute par une chimiotherapie suivie de la resection de la masse residuelle Les thymomes peuvent etre localement invasifs et associes a des manifestations auto-immunes. Une resection chirugicale complete est possible dans bon nombre de cas. La radiotherapie est recommandee pour les formes invasives ou incompletement resequees. Les thymomes invasifs sont chimiosensibles

A study was carried out to investigate the predictive value of 81-metastable-krypton (81mKr) distribution, high-size 99-metastable-technetium (99mTc) aerosol deposition and low-size 99mTc aerosol (Technegas) deposition on the pulmonary ventilation evaluated by 133-xenon (133Xe) lung scintigraphy, and to assess the correlation between the 81mKr distribution, the 99mTc aerosols deposition, and the respiratory parameters of patients with chronic obstructive pulmonary disease (COPD). Twenty COPD patients were included. The 81mKr, 133Xe, and 99mTc aerosol lung scintigraphies were successively carried out. The 81mKr distribution and 99mTc deposition were compared to the 133Xe distribution at equilibrium and to the 133Xe clearance. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 81mKr and Technegas lung scintigraphies to detect alterations in ventilation revealed by 133Xe were defined. The 81mKr distribution and 99mTc deposition according to respiratory parameters were described using a principal component analysis. Compared to 133Xe distribution, a significantly higher distribution of 81mKr in the upper parts of the lungs in the more severe patients (p = 0.05), a significantly higher deposition of Technegas in the lower parts of the lungs (p = 0.0008), and a significantly higher deposition in the central parts of the high-size 99mTc aerosol were observed (p = 0.0001). The PPV and the NPV were, respectively, 0.54 and 0.58 for 81mKr and 0.54 and 0.55 for Technegas. There was a significant negative correlation between 81mKr distribution and 133Xe clearance (p = 0.0001) between Technegas deposition and 133Xe clearance (p = 0.0007), and between 99mTc diethylene-triamino-penta-acetate (DTPA) deposition and 133Xe clearance (p = 0.001). Both the 81mKr peripheral distribution and Technegas peripheral deposition correlated negatively with increased obstruction, as measured by forced expiratory volume in 1 sec (FEV1). Peripheral deposition of the high-size 99mTc aerosol deposition correlated with the inspiration/expiration time ratio. In conclusion, 81mKr and 99mTc aerosols' lung scintigraphies do not reflect exactly the pulmonary ventilation as measured by 133Xe scintigraphy.

Aim: To characterize gemcitabine aerosol, its in vitro activity against lung cancer cells, its deposition, and tolerance in a non-human primate model. Methods: In vitro cytotoxicity of nebulized gemcitabine against NCI-H460 and A549 lung cancer cells was tested using a growth inhibition assay and compared with non-nebulized gemcitabine. The 99mTc-DTPA-radiolabeled gemcitabine aerosol was characterized by cascade impaction and the gemcitabine mass/99mTc activity relationship was established for further quantitative nuclear imaging. Nine weekly inhalations at a target dose of 1 mg/kg body weight of gemcitabine were performed in three baboons using dynamic scintigraphic acquisitions for continuous monitoring of gemcitabine delivery during inhalation. Gemcitabine plasma concentrations were measured during the first inhalation. Results: Growth inhibition assays for both NCI-H460 and A549 cells did not differ between nebulized and non-nebulized gemcitabine. Aerosol characterization showed a particle mass median aerodynamic diameter of 3.7±0.8 μm and a linear relationship between gemcitabine mass (y) and 99mTc activity (x) (y=0.82x − 10−5, R 2=0.88). No toxicity was observed after nine weekly inhalations of a mean dose of gemcitabine of 11.1 mg (88% of the target dose) as assessed from scintigraphic data. A dose-dependent peak plasma concentration of gemcitabine (20–74 ng/ml) was observed by the tenth minute of inhalation. Conclusions: We have characterized a gemcitabine aerosol suitable for intrathoracic airway deposition and demonstrated that jet nebulization does not alter the cytotoxic properties of the drug. In a primate model, we have developed a scintigraphic procedure for the monitoring of aerosol deposition, and we have demonstrated the safety of nine weekly aerosol administrations of gemcitabine.

Emerging data indicate that serine proteases of the kallikrein family (KLK) are implicated in various human diseases, including carcinoma; however, kallikrein gene expression has never been investigated in lung cancer. Using RT-PCR and Western blotting, we demonstrated the expression of both KLK5 and KLK7, and their respective proteins (hK5 and hK7) in tumoral and nontumoral lung tissues. Quantitative gene expression was then analyzed in a cohort of 56 patients with non-small cell lung cancer by real-time RT-PCR. KLK5 expression is significantly more expressed in squamous cell carcinoma than in matched nonmalignant lung tissue (P = 0.02), whereas expression of KLK7 was decreased in adenocarcinoma (P = 0.003). Multivariate analysis revealed diverse correlations between the KLK5 and KLK7 expression levels in nonmalignant and malignant tissues, and clinical parameters, including histotype, metastatic status, and grade. Our findings provide new insight into kallikrein gene expression in hormone-independent carcinoma. Altogether, our results suggest that variability in KLK5 and KLK7 gene expression might be involved in lung tumorigenesis and useful for clinical purposes.

Background This multicenter, randomized, phase III study compared the efficacy, including progression-free survival (PFS), and safety of gemcitabine–docetaxel (GD) combination versus cisplatin–vinorelbine (CV) in the treatment of advanced non-small-cell lung cancer (NSCLC). Patients and methods Chemonaive patients with stage IIIB or IV NSCLC were treated with GD (gemcitabine 1000 mg/m2 days 1 and 8 plus docetaxel 85 mg/m2 day 8, every 3 weeks for eight cycles) or CV (cisplatin 100 mg/m2 day 1 plus vinorelbine 30 mg/m2, days 1, 8, 15 and 22, every 4 weeks for six cycles). Results A total of 311 patients were enrolled (155 GD and 156 CV). Neither PFS nor overall survival differed significantly between the two arms (median PFS 4.2 and 4 months; median survival 11.1 and 9.6 months; 1-year survival 46% and 42%, for GD and CV, respectively). For the GD arm compared with the CV arm, the hazard ratio for PFS was 1.04 [95% confidence interval (CI) 0.83–1.32], and for overall survival, it was 0.90 (95% CI 0.70–1.16). Objective response rates did not differ significantly (31% for GD, 35.9% for CV). Myelosupression, emesis and frequency of febrile neutropenia were less pronounced on the GD arm, whereas fluid retention and pulmonary events were more pronounced. The CV arm experienced a higher number of serious adverse events and a lower compliance with the protocol. There was no quality of life (QoL) difference between arms. Median time to definite impairment of health-related QoL was 153 and 168 days in GD and CV arms, respectively. Conclusions There was no advantage in PFS with GD compared with CV; however, the CV regimen had higher rate of toxic events, mainly myelosuppression. The herein, non-platinum-containing regimen could be considered as a rational alternative to the cisplatin-based doublet.

International audience; Tissue factor pathway inhibitor-2 (TFPI-2) is a Kunitz-type serine proteinase inhibitor that inhibits plasmin-dependent activation of several metalloproteinases. Downregulation of TFPI-2 could thus enhance the invasive potential of neoplastic cells in several cancers, including lung cancer. In this study, TFPI-2 mRNA was measured using a real-time PCR method in tumours of 59 patients with non-small-cell lung cancer (NSCLC). Tumour TFPI-2 mRNA levels appeared well correlated with protein expression evaluated by immunohistochemistry and were 4-120 times lower compared to those of nonaffected lung tissue in 22 cases (37%). Hypermethylation of the TFPI-2 gene promoter was demonstrated by restriction enzyme-polymerase chain reaction in 12 of 40 cases of NSCLC (30%), including nine of 17 for whom tumour TFPI-2 gene expression was lower than in noncancerous tissue. In contrast, this epigenetic modification was shown in only three of 23 tumours in which no decrease in TFPI-2 synthesis was found (P ¼ 0.016). Decreased TFPI-2 gene expression and hypermethylation were more frequently associated with stages III or IV NSCLC (eight out of 10, P ¼ 0.02) and the TFPI-2 gene promoter was more frequently hypermethylated in patients with lymph node metastases (eight out of 16, P ¼ 0.02). These results suggest that silencing of the TFPI-2 gene by hypermethylation might contribute to tumour progression in NSCLC.

Resume On designe sous le terme de tumeur mediastinale d'origine embryonnaire les tumeurs qui resultent d'un trouble du developpement embryonnaire ou qui derivent de cellules germinales et dont le siege primitif est le mediastin. Ces tumeurs sont constituees de tissus ressemblant a ceux qui se succedent au cours du developpement depuis le stade embryonnaire jusqu'au stade adulte. Ces lesions, benignes ou malignes, sont classees selon leur histogenese et les possibilites therapeutiques. Les tumeurs germinales sont constituees de tissus ressemblant a ceux qui se succedent au cours du developpement, par differenciation des feuillets primordiaux et des feuillets extraembryonnaires. Du point de vue therapeutique, on distingue les seminomes, les tumeurs germinales non seminomateuses (TGNS) et les teratomes. Les kystes mediastinaux sont des malformations constituees de tissus normalement contenus dans la cavite thoracique adulte. Ils sont classes en cinq types selon leur structure : les kystes bronchogeniques et paraœsophagiens, les kystes pleuropericardiques, les lymphangiomes kystiques, les hemangiomes benins et les kystes meninges.

Background The survival benefit associated with first-line chemotherapy in advanced lung cancer led to the need for second-line chemotherapy. Docetaxel (Taxotere®) has proven efficacy in both settings. This study evaluated the safety and efficacy of two doses of docetaxel in patients with non-small-cell lung cancer who had failed first-line platinum-based chemotherapy. Patients and methods In total, 182 patients from 24 French centres were randomised and treated with either docetaxel 75 mg/m2 (arm A) or 100 mg/m2 (arm B) every 3 weeks. Baseline characteristics were well balanced, except more patients in arm A had metastatic disease (91.4% versus 78.7%) and therefore the median number of sites involved for arm A was three compared with two for arm B. Results Median time to treatment failure was 1.34 months [95% confidence interval (CI) 1.28–1.64] for arm A and 1.64 months (95% CI 1.34–2.62) for arm B. Median overall survival was 4.7 months (95% CI 3.8–5.9) for arm A versus 6.7 months (95% CI 4.8–7.1) for arm B. According to a blinded expert panel, disease control was achieved in 35 (43.8%) patients in arm A and 39 (49.4%) patients in arm B. More patients in arm B experienced grade 3–4 neutropenia (B: 72.7% versus A: 44.0%), asthenia (B: 20.2% versus A: 10.8%) and infection (B: 6.7% versus A: 2.2%). Three treatment-related deaths were reported in each arm. Conclusions The optimal docetaxel dosage in this second-line setting is 75 mg/m2, as it has a more favourable safety profile and on balance a similar efficacy to the 100 mg/m2 dose.

Aims: A case–control study was carried out between 1998 and 2000 to investigate the relation between systemic sclerosis and occupational exposure. Methods: Eighty cases of systemic sclerosis admitted consecutively to the Department of Internal Medicine at the University Hospital of Tours from 1998 to 2000 were included. For each case, two age, gender, and smoking habits matched controls hospitalised during the same period in the same department were selected. A committee of experts was set up retrospectively to assess occupational exposure. Exposure to silica dust and organic solvents (such as trichlorethylene and other chlorinated solvents, and benzene and other aromatic solvents) was investigated using semiquantitative estimates of exposure. An exposure score was calculated for each subject based on probability, intensity, daily frequency, and duration of exposure for each period of employment. The final cumulative exposure score was obtained, taking into account all periods of employment. Results: Significant associations with SS were observed for crystalline silica, trichlorethylene, chlorinated solvents, toluene, aromatic solvents, ketones, white spirit, epoxy resins, and welding fumes. Risk of SS was significantly associated with a high final cumulative exposure score of occupational exposure to crystalline silica, trichlorethylene, chlorinated solvents, welding fumes, and any types of solvents. Conclusion: Results confirm the influence of occupational risk factors in the occurrence of SS in both men and women. The link is not only with silica but also with other compounds such as solvents.

To evaluate whether preoperative chemotherapy (PCT) could improve survival in resectable stage I (except T1N0), II, and IIIA non-small-cell lung cancer (NSCLC).A randomized trial compared PCT to primary surgery (PRS). PCT consisted of two cycles of mitomycin (6 mg/m(2), day 1), ifosfamide (1.5 g/m(2), days 1 to 3) and cisplatin (30 mg/m(2), days 1 to 3), and two additional postoperative cycles for responding patients. In both arms, patients with pT3 or pN2 disease received thoracic radiotherapy.Three hundred fifty-five eligible patients were randomized. Overall response to PCT was 64%. There were two preoperative toxic deaths. Postoperative mortality was 6.7% in the PCT arm and 4.5% in the PRS arm (P =.38). Median survival was 37 months (95% confidence interval [CI], 26.7 to 48.3) for PCT and 26.0 months (95% CI, 19.8 to 33.6) for PRS (P =.15). Survival differences between both arms increased from 3.8% (95% CI, 1.3% to 25.1%) at 1 year to 8.6% (95% CI, 2.64% to 24.4%) at 4 years. A quantitative interaction between N status and treatment was observed, with benefit confined to N0 to N1 disease (relative risk [RR], 0.68; 95% CI, 0.49 to 0.96; P =.027). After a nonsignificant excess of deaths during treatment, the effect of PCT was significantly favorable on survival (RR, 0.74; 95% CI, 0.56 to 0.99; P =.044). Disease-free survival time was significantly longer in the PCT arm (P =.033).Although impressive differences in median, 3-year, and 4-year survival were observed, they were not statistically significant, except for stage I and II disease.

A randomized phase II trial of oral vs. intravenous (i.v.) vinorelbine was designed to determine the efficacy and safety of oral vinorelbine with an intrapatient dose escalation in previously untreated patients with advanced non-small-cell lung cancer (NSCLC).Between December 1997 and April 1999, 115 patients with stage IIIB or IV NSCLC were randomized (2 to 1) to receive either oral vinorelbine at a dose of 60 mg/m2/week for the first three administrations and then increased to 80 mg/m2/week in the absence of severe neutropenia, or i.v. vinorelbine at 30 mg/m2/week.One hundred and fourteen patients (76 in the oral arm and 38 in the i.v. arm) were treated. Ninety-eight patients (86%) were eligible and assessable. The two treatment arms were well-balanced for demographic and prognostic features. After external panel review, the response rates in evaluable patients were 14%, in the oral arm and 12% in the i.v. arm. The median progression-free survival with oral and i.v. vinorelbine was 3.2 months and 2.1 months, respectively, and the median survival 9.3 and 7.9 months, respectively. The most common hematological toxicity was neutropenia, which was severe (grade 3-4) in 46% of patients and for 7% of administrations in the oral arm, and in 62% of patients and for 25% of administrations in the i.v. arm. Non-hematological toxicities including nausea, vomiting, anorexia, weight loss, diarrhea .and constipation were generally mild to moderate.The activity of oral and i.v. vinorelbine in advanced NSCLC appears to be comparable. The safety profiles of both formulations look qualitatively similar. Oral vinorelbine can therefore be considered a good alternative to i.v. administration.

Context The 'Standards, Options and Recommendations' (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French cancer centres and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. Objectives To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone. Methods Data were identified by searching Medline and personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers, and to the medical committees of the 20 French cancer centres. Results The main recommendations for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone are: 1) The curative external irradiation with a continual course is an alternative to surgery only in the case of medically inoperable tumors or because the patient refuses surgery; 2) The external irradiation of the primary tumor only without the mediastinum could be proposed in peripheral stage IA. In proximal stage IA and IB, external irradiation should be carried out only as part of prospective randomised controlled trials comparing a localised irradiation of the primary tumor with a large irradiation of the mediastinum and the primary tumor. The treated volume must include the macroscopic tumoral volume with or without the microscopic tumoral volume and with a security margin from 1.5 to 2 cm; 3) There is a benefit to delivering a total dose in the primary tumor higher than 60 Gy in so far as the proposed irradiation, taking into account the respiratory function, does not increase the likelihood of severe adverse events due to radiation; and 4) The change in fractionation, the radiochemotherapy combination, the endobronchial brachytherapy with high dose rate alone or with external irradiation could be proposed only as part of prospective controlled trials for tumors classified as stage IB or II.

Using nebulization to deliver aminoglycosides may be of benefit in cystic fibrosis (CF) patients colonized byPseudomonas aeruginosa. However, one problem with this route is the absence of clinical parameters allowing estimation of the mass of drug deposited in the lungs (MDL). The aim of this study was to assess whether aminoglycoside excretion in the urine reflects the MDL.Fourteen studies were performed in seven CF patients. Amikacin was mixed with albumin labelled with99mTc and nebulized with an ultrasonic nebulizer. The MDL was determined by the mass-balance technique. Urine was collected during the 24 h following inhalation and was assayed for amikacin by fluorescence polorization immunoassay (FPIA).The mean±sem MDL was 14.0±2.2% of the nebulizer charge. The mean±sem amount of amikacin excreted in the urine was 20.9±4.5 mg and correlated with the MDL (r=0.93; p=0.0001). There was, however, wide intersubject variability in both deposition and excretion in the urine.Monitoring excretion of aminoglycosides in the urine allows noninvasive estimation of the mass of drug deposited in the lung in cystic fibrosis patients, which might be useful to assess the dose-response relationship in groups of patients, but intersubject variability prevents its use for individual follow-up.

Background: The combination of etoposide plus cisplatin (EP) is considered to be standard therapy for small-cell lung cancer (SCLC). To determine whether drug intensification improves survival of patients with extensive SCLC, we compared this treatment with a four-drug regimen containing EP plus cyclophosphamide and 4'-epidoxorubicin (PCDE). Methods: In a phase III clinical trial organized by the French Federation of Cancer Institutes, patients were randomly assigned to receive either EP (n = 109; etoposide at a dose of 100 mg/m 2 on days 1-3 plus cisplatin at 100 mg/m 2 on day 2) or PCDE (n = 117; etoposide and cisplatin given as in EP plus cyclophosphamide at 400 mg/m 2 on days 1-3 and 4'-epidoxorubicin at 40 mg/m 2 on day 1) every 4 weeks. Both groups received a total of six cycles. Survival differences were analyzed by Wilcoxon and log-rank tests. Associations of treatment group and putative prognostic variables with survival were tested in the Cox proportional hazards model. Quality of life was assessed from the responses to the European Organization for Research and Treatment of Cancer quality-of-life questionnaire (C30, health status and lung cancer module 13). All statistical tests were two-sided. Results: Patients in the PCDE arm had a statistically significant higher frequency of combined complete plus partial responses compared with those in the EP arm (21% plus 55% versus 13% plus 48%, respectively; P = .02 for difference in combined objective responses). Patients in the PCDE arm survived longer than those in the EP arm (1-year survival rate: 40% and 29%, respectively; median survival: 10.5 and 9.3 months, respectively; log-rank P = .0067). In the Cox model, the relative risk of death for patients in the PCDE arm compared with those in the EP arm was 0.70 (95% confidence interval = 0.51 to 0.95); the disease also progressed more slowly in patients in the PCDE arm. Hematologic toxicity was higher in the PCDE arm (22% with documented infections compared with 8% in the EP arm; P = .0038), and the toxicity-related death rate was 9% in the PCDE arm versus 5.5% in the EP arm (P = .22). The global health status showed similar improvement in both arms during treatment. Conclusion: Compared with the EP regimen, the PCDE regimen yielded higher response rates and better survival rates in patients with extensive SCLC without affecting the quality of life of the patients during chemotherapy.

Study objective To determine the value of the level of anti-topoisomerase I (anti-topo I) to evaluate lung involvement defined by abnormal high-resolution computed tomography (HRCT) score and pulmonary function tests (PFTs) in systemic sclerosis (SS). Patients Forty-eight patients with SS, 20 with lung involvement and 28 with no lung involvement. Design PFT measurement, HRCT scoring of lung involvement, and anti-topo I assay by enzyme-linked immunosorbent assay. Normal anti-topo I level was defined as Results There was a significant association between cutaneous extent and anti-topo I level (6.5% of patients with limited cutaneous scleroderma had abnormal anti-topo I levels vs 70.6% of patients with diffuse cutaneous scleroderma, p = 0.0001). In patients with diffuse cutaneous scleroderma, pulmonary involvement was associated with a higher percentage of abnormal anti-topo I level: 91.7% vs 20% (p = 0.010). In patients with diffuse cutaneous scleroderma, a significant association was found between the class of anti-topo I level and total lung capacity (median, 69 in patients with abnormal anti-topo I level vs 87 in patients with normal anti-topo I level, p = 0.010), between the class of anti-topo I level and HRCT score (median, 12 in patients with abnormal anti-topo I level vs 5 in patients with normal anti-topo I level, p = 0.05). Conclusion Anti-topo I can be considered as a marker of lung involvement in patients with diffuse cutaneous scleroderma.

To determine the predictive value of abnormalities on high-resolution CT (HRCT) on pulmonary disease in systemic sclerosis.Fifty-two patients suffering from systemic sclerosis.Pulmonary disease was defined by pulmonary function test abnormalities, ie, total lung capacity (TLC)80% of predicted value and/or diffusion of carbon monoxide (DLCO)75% of predicted value, without any pulmonary event other than systemic sclerosis in the medical history. Patients were divided in two groups, group A with pulmonary disease (29 patients) and group B without pulmonary disease (23 patients). HRCT abnormalities were scored on whole lungs. A decision matrix was constructed to determine sensitivity, specificity, positive and negative predictive values, and false-positive and false-negative rates. A receiver operating characteristic curve was constructed to determine the best compromise between sensitivity and specificity.HRCT total scores were higher in group A (9.0+/-4.3) than in group B (5.0+/-2.8) (p0.001) and they correlated with TLC (r =-0.39, p0.005) and DLCO (r = -0.50, p0.0002). An HRCT score of 7 corresponded to the best compromise between sensitivity (0.60) and specificity (0.83), with a positive predictive value of 0.82. Taking into account a value of 10 for the HRCT score increased specificity to 1 but decreased sensitivity to 0.41.A minimum score of 7 would be required to consider HRCT abnormalities in systemic sclerosis as predictive of pulmonary disease. An HRCT score of 10 makes it possible to establish the diagnosis of lung involvement severe enough to impair pulmonary function.

International audience; Monoclonal antibodies (mAbs) are usually delivered systemically, but only a small proportion of the drug reaches the lung after intravenous injection. The inhalation route is an attractive alternative for the local delivery of mAbs to treat lung diseases, potentially improving tissue concentration and exposure to the drug while limiting passage into the bloodstream and adverse effects. Several studies have shown that the delivery of mAbs or mAb-derived biopharmaceuticals via the airways is feasible and efficient, but little is known about the fate of inhaled mAbs after the deposition of aerosolized particles in the respiratory system. We used cetuximab, an anti-EGFR antibody, as our study model and showed that, after its delivery via the airways, this mAb accumulated rapidly in normal and cancerous tissues in the lung, at concentrations twice those achieved after intravenous delivery, for early time points. The spatial distribution of cetuximab within the tumor was heterogeneous, as reported after i.v. injection. Pharmacokinetic (PK) analyses were carried out in both mice and macaques and showed aerosolized cetuximab bioavailability to be lower and elimination times shorter in macaques than in mice. Using transgenic mice, we showed that FcRn, a key receptor involved in mAb distribution and PK, was likely to make a greater contribution to cetuximab recycling than to the transcytosis of this mAb in the airways. Our results indicate that the inhalation route is potentially useful for the treatment of both acute and chronic lung diseases, to boost and ensure the sustained accumulation of mAbs within the lungs, while limiting their passage into the bloodstream.

Colistin aerosols are frequently administered to patients with cystic fibrosis. However, questions arise concerning the effect of both jet and ultrasonic nebulizers on the properties of the drug. The aim of this study was to characterize the anti-Pseudomonas aeruginosa (PA) activity of colistin after jet (Pari LL) and ultrasonic (DP100) nebulization. A bench study was performed by capturing the aerosols, determining the drug mass, and assessing its anti-PA activity. Because the inhaled mass of colistin had to be entirely recovered for the bacteriological study, it was assessed by isotopic methods, mixing the drug with a 99mTc-labelled tracer and demonstrating that 99mTc activity accurately predicted the mass of colistin. Colistin was extracted from the filters and its antibiotic activity was determined using the method employed for the study of the bacteriostatic and bactericidal power of serum on the ATCC 27853 PA strain. The postnebulization minimum inhibitory concentrations (MIC) were 1.9 micrograms.mL-1 with DP100 and 0.5 microgram.mL-1 with Pari LL. These values were less than two dilutions different from the 1 microgram.mL-1 MIC of non-nebulized colistin. We conclude that neither jet nebulization nor ultrasonic nebulization alter the antibiotic properties of colistin and that both systems can be used to nebulize colistin.

Airflow obstruction in chronic obstructive pulmonary disease (COPD) is due to the combination of airway disease and emphysema, may be accompanied by airway reactivity, and may be partially reversible. Aerosol deposition is affected by airway geometry. Deposition patterns in COPD are increasingly abnormal as the forced expiratory volume in 1 second (FEV1) percentage deteriorates. More advanced COPD is characterized by the formation of multiple impactions in the central airways and a marked reduction in peripheral deposition. Vagal innervation is most prominent in the central airways, although beta-adrenergic receptors are more widely distributed in small airways. Anticholinergics and beta agonists are effective bronchodilators in COPD. With large doses of either ipratropium or beta agonists, most studies have demonstrated equivalent bronchodilation in stable COPD. Small, conventional doses of the two agents are additive, and large doses are not. In COPD patients with acute exacerbation, nebulized ...

The purpose of this study was to determine the ability of technetium-99m J001X scintigraphy to image active pulmonary involvement in patients suffering from rheumatoid arthritis (RA). J001X is a fully characterized acylated poly(1,3)galactoside, isolated from Klebsiella membranes, which is able to bind recruited macrophages after aerosol administration. J001X scintigraphy was compared with high-resolution computed tomography (HRCT), pulmonary function tests (PFTs) and bronchoalveolar lavage (BAL) in 15 patients suffering from RA. Patients were considered to have pulmonary involvement when they had an interstitial syndrome on HRCT and a decrease of 20% in TCO/VE (transfer coefficient) on PFTs and/or an abnormal BAL (lymphocytosis higher than 20% and/or percentage of neutrophils higher than 10%). Pulmonary involvement was present in eight patients, and absent in seven. Of the eight patients with pulmonary involvement, all had abnormal BAL, two had an interstitial syndrome on HRCT, two had decreased TCO/VE and three had positive J001X scintigraphy. Of the seven patients without pulmonary involvement, six had normal BAL (not available in one), two had an interstitial syndrome on HRCT, one had decreased TCO/VE and two had positive J001X scintigraphy. According to our gold standard of pulmonary involvement, the sensitivity of J001X scintigraphy for the detection of pulmonary involvement in RA was 37.5%, the specificity was 71.4% and the positive predictive value was 60%. The ability of J001X scintigraphy to detect active pulmonary involvement during RA appears unclear in this study but it may detect processes unnoticed by the other modalities. These patients will be followed 12 and 24 months later and the changes in J001X scintigraphy, HRCT and PFTs will be compared to demonstrate whether J001X scintigraphy is able to assess an active process in the pulmonary involvement during RA and to specify its predictive value.

The aim of the present study was to characterize amphotericin B aerosols nebulized by ultrasonic and jet nebulizers and to study their deposition and pharmacokinetics in patients with pulmonary mycetoma. The aerodynamic behaviour and pulmonary deposition of amphotericin B particles were measured using a direct isotopic method based on stable labelling of the drug with 99mTc. Each nebulizer was bench tested for inhaled mass and particle size distribution. Three patients suffering from pulmonary aspergilloma were enrolled for a 4 week clinical study. They received 5 mg of amphotericin B daily delivered by either Fisoneb or DP100 (ultrasonic) or Respirgard II (jet) nebulizers. Deposition of radiolabelled amphotericin B was measured once with each nebulizer using a gamma-camera. In two patients, amphotericin B serum concentration was monitored over a 330 min period after the nebulization had been completed. Inhaled masses of the three nebulizers, assessed as % of labelled drug caught in inspiratory filter in duplicate experiments, were: 5.8 and 3.6% for Respirgard II; 26.5 and 28.3% with Fisoneb; 5.9 and 6.3% for DP100. Mass median aerodynamic diameter (mean +/- SD) results were: 0.28 +/- 0.04 micron with Respirgard II; 4.82 +/- 0.78 microns with Fisoneb; and 2.27 +/- 1.14 microns with DP100. Because of larger particles and significantly greater inhaled mass, Fisoneb delivered more amphotericin B to the central airways, the lung periphery and in the mycetoma lung regions. Amphotericin B serum concentrations correlated with pulmonary deposition and remained below 25 ng.mL-1. No untoward effects were reported by the patients during the 4 week trial.(ABSTRACT TRUNCATED AT 250 WORDS)

Background Despite advances in cancer therapy, mortality is still high except in early-stage tumors, and screening remains a challenge. The randomized National Lung Screening Trial (NLST), comparing annual low-dose computed tomography (LDCT) and chest X-rays, revealed a 20% decrease in lung-cancer-specific mortality. These results raised numerous questions. The French intergroup for thoracic oncology and the French-speaking oncology group convened an expert group to provide a coherent outlook on screening modalities in France. Methods A literature review was carried out and transmitted to the expert group, which was divided into three workshops to tackle specific questions, with responses presented in a plenary session. A writing committee drafted this article. Results The multidisciplinary group favored individual screening in France, when carried out as outlined in this article and after informing subjects of the benefits and risks. The target population involves subjects aged 55–74 years, who are smokers or have a 30 pack-year smoking history. Subjects should be informed about the benefits of quitting. Screening should involve LDCT scanning with specific modalities. Criteria for CT positivity and management algorithms for positive examinations are given. Conclusions Individual screening requires rigorous assessment and precise research in order to potentially develop a lung-cancer screening policy.
