Clinical TrialA phase II trial of surgical resection and adjuvant high-dose hemithoracic radiation for malignant pleural mesothelioma.
Surgical resection of malignant pleural mesothelioma is reported to have up to an 80% rate of local recurrence. We performed a phase II trial of high-dose hemithoracic radiation after complete resection to determine feasibility and to estimate rates of local recurrence and survival. ⋯ Hemithoracic radiation after complete surgical resection at a dose not previously reported is feasible. This approach dramatically reduces local recurrence and is associated with prolonged survival for early-stage tumors. Stage III disease has a high risk of early distant relapse and should be considered for trials of systemic therapy added to this regimen of resection and radiation.

Comparative StudyA morphologic study of Carpentier-Edwards pericardial xenografts in the mitral position exhibiting primary tissue failure in adults in comparison with Ionescu-Shiley pericardial xenografts.
We sought to investigate the durability and mechanism of the Carpentier-Edwards pericardial xenograft in the mitral position in comparison with that of the Ionescu-Shiley pericardial xenograft. ⋯ Tissue overgrowth on the atrial surface, ventricular surface, or both was the cause of structural valve deterioration, nonstructural valve deterioration, or both of Carpentier-Edwards pericardial xenografts in adults. This was different from Ionescu-Shiley pericardial xenograft failure, which resulted from severe calcification and leaflet tears. Organized thrombi on cusps, in addition to valve design, may have contributed to such tissue overgrowth on Carpentier-Edwards pericardial xenografts.

Randomized Controlled Trial Clinical TrialLow-dose postoperative aprotinin reduces mediastinal drainage and blood product use in patients undergoing primary coronary artery bypass grafting who are taking aspirin: a prospective, randomized, double-blind, placebo-controlled trial.
Although low-dose aprotinin administered after cardiopulmonary bypass has been reported to reduce mediastinal blood loss and blood product requirements in patients not taking aspirin, it is unknown whether low-dose postoperative aprotinin has any beneficial effects in patients undergoing coronary artery bypass operations who are at high risk of excessive postoperative bleeding and increased transfusion requirements because of aspirin use until just before the operation. ⋯ These results suggest that postoperative administration of low-dose aprotinin in patients taking aspirin until just before primary coronary artery operations with cardiopulmonary bypass not only reduces the rate and total amount of postoperative mediastinal blood loss but also lowers postoperative blood product use.

Surgical treatment of primary lung cancer with synchronous brain metastases.
The role of surgical resection for brain metastases from non-small cell lung cancer is evolving. Although resection of primary lung cancer and metachronous brain metastases is superior to other treatment modalities in prolonging survival and disease-free interval, resection of the primary non-small cell lung cancer and synchronous brain metastases is controversial. ⋯ Although the overall survival for patients who have brain metastases from non-small cell lung cancer is poor, surgical resection may prove beneficial in a select group of patients with synchronous brain metastases and lung cancer without lymph node metastases.
