[Endobronchial ultrasound transbronchial needle aspiration initiation into the Lyon Sud hospital center: Experience of the first three years]. / Initiation de la technique d'écho-endoscopie bronchique au centre hospitalier Lyon-Sud : expérience des trois premières années.

INTRODUCTION: Endobronchial ultrasound is a recent technique for the diagnosis and the lymph node staging in lung cancer. It also showed interest in non tumoral mediastinal lymph nodes diagnosis. This work relates the CHLS first three years' experience in terms of EEB practical use as a new diagnostic tool in this field. METHODS: Retrospective study of consecutive cases patients having undergone endobronchial ultrasound from November 2008 till June 2011 in the CHLS. RESULTS: On 65 endobronchial ultrasound, general anesthesia was practiced in 89 % of the cases, with a good tolerance in 81 % of the cases. In 77 % cases, EEB allowed diagnosis and avoided mediastinoscopy in 60.5 % of the cases. The respective sensibility, specificity, positive and negative predictive values were 74 %, 100 %, 100 % and 48 %. CONCLUSION: These data, reflect of a novice team experience, illustrate the results obtained in the current practice in terms of etiologic diagnosis. Endobronchial ultrasound seems destined to a bright future but requires the development of dedicated centers allowing pulmonologists training and specialized pathologists in this field.

[Patient's beliefs about oral targeted therapies and impact on drug adherence in lung cancer: A pilot prospective study]. / Croyances des patients envers les thérapies ciblées orales et leur influence sur l'observance dans le cancer broncho-pulmonaire : une étude pilote prospective.

INTRODUCTION: Oral targeted therapies are a new option for lung cancer treatment. However, patient's belief about these drugs - which may interact with adherence - is poorly known in this setting. METHOD: Our study is a pilot prospective unicentric study. Inclusion criteria were: to have been diagnosed with a lung cancer; and to be prescribed with an oral targeted therapy in second line or more. The main objective was to assess patient's specific (SB) and general beliefs (GB) about these drugs according to the Beliefs about Medicines Questionnaire (BMQ). The declared adherence was assessed with the Morisky's test. All included patients underwent a semi-structured interview with a psychologist. RESULTS: Fifthteen patients were included: 12 underwent erlotinib treatment and 3 a crizotinib treatment. The mean score (±standard deviation) at BMQ was 54/85 (±6) overall; 34/50 (±5) for specific belief and 19/35 (±3) for general belief about drugs. During interview, 47% believed in efficacy of targeted oral therapy; 93% reported concerns about their drug; 80% considered that the information given by the physician about the drug was comprehensive; but 40% still required additional information about it. The mean score at Morisky's test was 3/4 (±2) and 53% reported to have forgotten at least once their antineoplastic drug. No correlation was found between belief and adherence. CONCLUSION: Belief about t anti-cancer targeted oral therapy is relatively fair but adherence is moderate in this pilot study. Interview shows the need for additional information about the prescribed drug.
