RESUMO
INTRODUCTION: Stage IVa thymoma is a rare disease without a standard of care. Subtotal pleurectomy and HITHOC introduced in highly selected patients may provide interesting oncologic results. The purpose of this study was to distinguish de novo stage IVa tumors (DNT) from distant relapse (DR) with respect to post-operative and long-term outcomes to provide the procedure efficacy. METHODS: From July 1997-December 2021, 40 patients with IVa pleural involvement were retrospectively analyzed. The surgical procedure was subtotal pleurectomy and HITHOC (cisplatin 50 mg/m2, mitomycin 25 mg/m2, 42 °C, 90 min). The post-operative outcome, disease-free interval (DFI) and overall survival (OS) were analyzed. RESULTS: Mean age was 52 ± 12 years. B2 and B3 thymomas were preponderant (27; 67.5%). The median number of pleural nodes were nine (4-81) vs. five (1-36); p = 0.004 * in DNT and DR, respectively. Hospital mortality rate was 2.5%. There were four specific HITHOC complications (10%). DFI were 49 and 85 months (p = 0.02 *), OS were 94 and 118 months (NS), in DNT and DR, respectively. CONCLUSIONS: Subtotal pleurectomy with HITHOC in IVa offers satisfying results in highly selected patients, for both DNT and DR. Due to the disease rarity, multicentric studies are needed to define HITHOC as a standard of care.
RESUMO
We describe a patient with polytrauma that included anterior chest flail caused by a fall while climbing. As the situation was similar to a pectus excavatum, we attempted to stabilize the depressed chest wall by using a vacuum bell. Deep breath, peak flow, and pectus index were increased when the patient used the vacuum bell. Conservative treatment with a vacuum bell during the day and continuous positive airway pressure during the night was undertaken for 6 weeks. This report documents stabilization of an anterior flail chest using a vacuum bell.
