RESUMO

Carcinoids are malignant neuroendocrine neoplasms showing good long-term survival after oncologic therapy. The study evaluated the influence of operative strategies and individual decision-making on the outcome and long-term survival in 222 patients with bronchial carcinoids. The patients underwent preoperative pulmonary function tests and bronchoscopy to facilitate surgical decision-making. A hundred and twelve tumors were detected endoscopically, including 32 in the main and lobar bronchi. We performed 5 isolated bronchus resections, 4 segmentectomies, 15 wedge resections, 10 pneumonectomies, 19 sleeve resections, 26 bilobectomies, 138 lobectomies, and 2 chest wall resections. Three patients were technically inoperable. Systematic mediastinal lymphadenectomy was routinely performed although most patients' computer tomography scans showed N0. A hundred and sixty-two patients had typical (155 N0, 7 N+) and 60 patients had atypical carcinoids (39 N0, 21 N+). There was no intraoperative mortality. The hospital mortality was below 2%. Overall, 1-, 5-, and 10-year survival rates were 99%, 94%, and 89%, respectively, in typical carcinoids. Atypical carcinoids show similar 1- and 5-year survival rates, but the 10-year survival rate was below 70%, decreasing in higher N-stages. The N-stage was the most important survival factor. In conclusion, bronchial carcinoids should be surgically treated the way lung cancer is. Anatomic resection and systematic lymphadenectomy are the treatments of choice. The availability of bronchoplastic techniques and preoperative assessment is essential for individual decision-making, focusing predominantly on postoperative quality of life.

RESUMO

BACKGROUND: Major thoracic wall resections require the implantation of foreign materials for reconstruction and stabilization. Recently, biological collagen matrixes have emerged as an alternative to the routinely used synthetic materials. MATERIALS AND METHODS: Retrospectively, we analyzed our initial experience of chest wall reconstruction on large defects using a cross-linked porcine dermal acellular collagen matrix mesh with a thickness of 1.5 mm. RESULTS: Six sarcoma patients with a mean age of 46 (22-66) years underwent chest wall resections. Complete thoracic wall defects (mean area 149 cm2) ranged from 8 × 10 to 15 × 20 cm in size. In the majority of cases, only mobilized subcutaneous tissue and skin were used for soft-tissue coverage of the implanted porcine collagen matrix patches. Implantation and postoperative courses were uneventful in all patients. No local infections or wound healing problems occurred. The collagen material resulted in durable and good to excellent chest wall stability in clinical follow-ups, and on computed tomography scans spanning over 3.5 years. Histological examination showed integration, neovascularization, and long-term persistence of the collagen matrix on late reoperation of one patient. CONCLUSION: Acellular porcine dermal collagen matrix is a feasible and reliable biological patch material for reconstruction of the thoracic wall. Excellent wound healing and long-term stability are achieved even in large defects or complete sternal replacements.

RESUMO

BACKGROUND: Severe pectus excavatum may be present in combination with cardiac conditions requiring open-heart surgery. The best strategy for this situation has been debated controversially. PATIENTS AND METHODS: In a retrospective study, we analyzed all our patients undergoing concurrent pectus excavatum correction and open-heart surgery. RESULTS: Ten patients aged 9 to 70 years underwent a simultaneous combined surgical procedure between 2001 and 2013. Indications for cardiac surgery were various forms of congenital and acquired heart disease including coronary artery disease with internal thoracic artery grafts and ascending aortic aneurysms. A modified Ravitch procedure was performed for pectus excavatum correction (mean Haller-Index 5.0). Mean operating time was 364 (210-495) minutes and mean duration of cardiopulmonary bypass was 125 (54-222) minutes. All procedures were completed successfully. Postoperatively minor complications were observed in three patients. In-hospital and 30-day mortalities were nil. Good cosmetic and functional results were achieved in all patients. CONCLUSIONS: Our data demonstrate that simultaneous pectus excavatum correction and cardiac surgery is effective and reliable. A combined approach is advocated if candidates for cardiac surgery present with significant pectus excavatum deformity.

RESUMO

Background: Lung cancer is the worldwide leading oncological cause of death in both genders combined and accounts for around 40-50% of brain metastases in general. In early-stage lung cancer, the incidence of brain metastases is around 3%. Since the early detection of asymptomatic cerebral metastases is of prognostic value, the aim of this study was to analyze the incidence of brain metastases in early-stage lung cancer and identify possible risk factors. Methods: We conducted a retrospective multicentric analysis of patients with Stage I (based on T and N stage only) Non-Small Cell Lung Cancer (NSCLC) who had received preoperative cerebral imaging in the form of contrast-enhanced CT or MRI. Patients with a history of NSCLC, synchronous malignancy, or neurological symptoms were excluded from the study. Analyzed variables were gender, age, tumor histology, cerebral imaging findings, smoking history, and tumor size. Results were expressed as mean with standard deviation or median with range. Results: In total, 577 patients were included in our study. Eight (1.4%) patients were found to have brain metastases in preoperative brain imaging. Tumor histology was adenocarcinoma in all eight cases. Patients were treated with radiotherapy (five), surgical resection (two), or both (one) prior to thoracic surgical treatment. Other than tumor histology, no statistically significant characteristics were found to be predictive of brain metastases. Conclusion: Given the low incidence of brain metastases in patients with clinical Stage I NSCLC, brain imaging in this cohort could be avoided.
