[Treatment and prognosis of advanced stage non-small-cell lung cancer]. / Traitement et pronostic du cancer bronchique non à petites cellules au stade avancé.

INTRODUCTION: Lung cancer is the main cause of death from cancer in both men and women worldwide. In 70 to 80% of cases, the diagnosis is made at an advanced stage. Although the management of non-small-cell lung cancer (NSCLC) has continued to improve over the last 5 years, the prognosis remains poor with a 5-year survival rate of about 16%. The aim of this study was to evaluate the management of locally advanced or metastatic NSCLC in our patients and to analyze overall survival (OS) and prognostic factors at these stages. MATERIALS AND METHODS: A retrospective study, including cases of locally advanced and metastatic NSCLC diagnosed in our department between 2008 and 2011. RESULTS: We included 150 patients with a mean age of 60.2 years. The cancer was at stage IIIA in 21% of cases, IIIB in 14% of cases and IV in 65% of cases. Thoracic surgery was performed in 5 patients; 61.4% of patients received chemotherapy and chemo-radiotherapy was given in 21% of patients. Overall survival was 6 months. Better survival was observed in patients aged less than 60 years, having better performance status (PS), having no metastatic mediastinal lymph nodes and patients who received specific anti-tumor treatment. CONCLUSIONS: The prognostic factors in locally advanced and metastatic NSCLC in our patients were: age, PS, status of mediastinal lymph nodes at diagnosis and treatment. These factors should be considered by physicians when treating patients with advanced stage NSCLC.

[Benign schwannoma with high uptake of 18 fluorodeoxglucose (PET-Scan)]. / Un cas de schwannome bénin avec hypermétabolisme sur la tomoscintigraphie TEP au 18fluorodésoxyglucose.

INTRODUCTION: In patients with a previous history of malignancy, the occurrence of a mediastinal mass with significant uptake of 18 Fluorodeoxyglucose on a PET-scan may lead to biopsy or resection. CASE REPORT: We report the case of a posterior mediastinal mass, with significant uptake of 18 Fluorodeoxyglucose on PET- scan, in a patient with a previous history of testicular seminoma. The lesion was actually a benign schwannoma. CONCLUSIONS: In the case of a mediastinal mass with conventional imaging being in favour of a neurogenic tumour a PET scan cannot confirm benignity or malignancy.

[Management of postoperative chylothorax]. / Prise en charge des chylothorax post opératoires.

INTRODUCTION: A chylothorax can occur following any intrathoracic procedure. It is generally straightforward to make the diagnosis but optimal management can be problematic. METHODS: Between 1995 and 2002, three women and one man aged from 13 to 58 years were treated for chylothorax after thoracic surgery. Their initial illnesses were a right pulmonary hydatid cyst associated with hepatic disease, a tumour of the posterior mediastinum, an oesophageal carcinoma and metastases in the left lung. RESULTS: These patients had: a pulmonary and hepatic cystectomies, a resection of the mediastinal tumor, an Akyama oesophagectomy and a resection of four left pulmonary metastases. Chylothorax became apparent post operatively between the 1st and the 4th day. All patients were treated with a medium-chain triglyceride diet. Two patients were re-explored with ligation of lymphatic vessels. One woman who did not have further surgery was treated with etilefrine. In the patient who had had an oesophagectomy, chylothorax persisted after re-operation. He was successfully treated by talc pleurodesis via a chest drain, which prevented further recurrence. CONCLUSIONS: In the management of postoperative chylothorax, medical treatment must be started early but surgery should not be delayed as operative risk is increased by the development of malnutrition and immune deficiency.
