[Paclitaxel-bevacizumab is a possible alternative as salvage chemotherapy in advanced non-small cell bronchial carcinoma]. / L'association paclitaxel-bevacizumab est une alternative intéressante dans le traitement des cancers bronchopulmonaires non épidermoïdes avancés en troisième ligne et plus.

INTRODUCTION: Bevacizumab is recommended in first line chemotherapy for advanced non-squamous non-small cell lung cancer (NSCLC). Paclitaxel is a doublet drug also widely used in cisplatin-based regimens. Paclitaxel plus bevacizumab is a standard regimen as first line treatment of metastatic breast cancer. Since there is no guideline for third line treatment of NSCLC, some oncology units use paclitaxel-bevacizumab in some NSCLC patient after relapse of the second line. The aim of this study was to assess retrospectively the feasibility and efficacy of this treatment option in stage IV NSCLC. METHODS: Patients who had received the combination of paclitaxel (80 to 90 mg/m(2) in a weekly schedule) and bevacizumab (7.5 to 15 mg/kg every 21 days) in the thoracic oncology departments of two university hospitals in the Rhone-Alpes Department were retrospectively reviewed. RESULTS: Twelve patients underwent this treatment. Their mean age was 56 years and their performance status was less or equal to 1 in 50 % of the cases. The chemotherapy was given as fifth line in 67 % of the patients and 67 % were antiangiogenic naïve. They received a mean of 6 courses. The overall response rate was 33 % and the disease control rate 66 %. Median progression-free survival was 5.1 months (95 %CI 1.0-9.1). Ten patients (82 %) experienced toxicity, the majority grade 1 to 2 events, and only one a grade 3 event (febrile neutropenia). There were no severe bleeding episodes. CONCLUSION: Combined paclitaxel-bevacizumab chemotherapy seems feasible in patients with NSCLC. The toxicity profile is acceptable. This regimen should be evaluated in further prospective studies.

[Pulmonary diffusion test to NO and CO time course during thoracic radiotherapy for lung cancer: the CONORT prospective study protocol]. / Évolution de la double diffusion au CO et au NO au cours de la radiothérapie pulmonaire pour cancer bronchique : présentation du protocole de l'étude prospective Conort.

Thoracic radiotherapy is a usual treatment for lung cancer. Early-stages may be treated in stereotactic mode while locally advanced stages are usually treated with conventional radiotherapy mode. Pulmonary function tests show that thoracic irradiation has no impact on lung volume such as forced expiratory volume in one second (FEV1) or forced vital capacity (FCV). However, some studies found that CO (carbon monoxide) diffusing capacity (TLCO) may be altered under thoracic radiotherapy. DLCO alteration is usually symptomatic of either a lesion in the alveolar membrane or a pulmonary capillary alteration. Pulmonary diffusion may be also appreciated by the NO (azote monoxide) diffusion capacity. Moreover, using a double measurement of NO and CO diffusing capacities permit to assess which lung compartment (capillary or membrane) is affected. CONORT is an observational prospective monocentric study, aiming to assess the CO and NO diffusing capacity (as well as other pulmonary function tests) during thoracic radiotherapy. Inclusion criteria are patients with lung cancer, treated by thoracic radiotherapy (conformational or stereotactic), who signed consent. Pulmonary function tests are performed before, during, at the end and six weeks and six months after thoracic irradiation. To estimate a difference of 15% in diffusing capacity test, we have to include 112 patients with a 90% power and a 5% alpha risk. Four months after beginning, 36 patients were included. Preliminary data will be presented at the SFRO meeting.

[Late revelation of air embolism after transthoracic needle biopsy]. / Embolie gazeuse de révélation tardive après ponction transpariétale pulmonaire.

INTRODUCTION: Percutaneous transthoracic needle biopsy is a useful and common procedure in the investigation of a lung nodule. The occurrence of air embolism after percutaneous transthoracic needle biopsy is extremely rare. CASE REPORT: We report a 62-year-old woman who presented with neurological signs including restlessness, meningeal signs and focal neurologic deficits 4 hours after percutaneous transthoracic lung biopsy, related to air embolism. The outcome was favorable with hyperbaric oxygen therapy. CONCLUSION: Percutaneous transthoracic needle biopsy complicated by air embolism has been rarely reported. It usually occurs within minutes after the biopsy. The late onset of this adverse event in our patient is exceptional. Air embolism occurs more frequently after biopsy of lung infiltrates compared to nodules. Occurrence of a pneumothorax or an intraalveolar haemorrhage following a percutaneous transthoracic needle biopsy may be warning manifestations and justify a close monitoring.
