LES PERTES DE SUBSTANCES PARIETALES THORACIQUES APRES EXERESE DE TUMEURS

The authors report 8 patients undergoing chest wall resection and 12 patients submitted to en bloc lung and chest wall resection. In the first group, 48 ± 15 years old, there were 3 females (Darier-Ferrand fibrosis, chondroma, cutaneous gland epithelioma) and 5 males (3 sarcomas, 1 metastasis and 1 osteofibroma). An average of 2 ribs were resected with muscles, pleura and in 3 cases the skin, amounting to between 300 and 1,000 g. Reconstruction was performed: 1° by musculocutaneous flap in 4 cases with 1 fistula; 2° Marlex Mesh in 2 cases with 1 infection; 3° fascia lata in the largest resection that necessitated tracheostomy and prolonged ventilation. There was no death. In the second group, 61 ± 14 years old, all males, there were 9 bronchial carcinomas and 3 sarcomas. On average 2.5 ribs were resected en bloc with 6 lungs and 6 lobes. The defect was treated :1° by Marlex Mesh in 3 cases without complications, 2 having tracheostomy and 2 days ventilation; 2° by muscle flap in 9 cases with 3 tracheostomies and ventilation up to 1 month :there were 3 empyemas and 2 atelectasiae. One patient died after a second operation for bronchial stump necrosis. On the whole there is no need for Marlex Mesh.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Imagerie des cancers en tomographie par émission de positons.

Positron emission tomography (PET) is a method making use of short half-life radioactive compounds which allow imaging and quantification of functional and metabolic data at the level of multiple organs. This method has been initially oriented towards neurological and cardiological applications but gets now a more widespread use in oncology. This recent development has been made possible thanks to methodological progresses allowing "whole body" imaging and thanks to the use of a practical tracer, the 2-[18 F]fluoro-2-deoxy-D-glucose (FDG). The uptake of this tracer is enhanced in diverse cancer tissues. Recent studies has clarified the biological processes which lead to this enhanced uptake of FDG in cancers. This new insight allows a rational and helpful usage of PET in diverse aspects of clinical oncology: diagnosis of lesion, staging, follow-up of patients and treatment evaluation.English AbstractJournal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe
