BACKGROUND Clinical trials have indicated a benefit of adjuvant chemotherapy for patients with stage IB, II, or IIIA--but not stage IA--non-small-cell lung cancer (NSCLC). This classification scheme is probably an imprecise predictor of the prognosis of an individual patient. Indeed, approximately 25 percent of patients with stage IA disease have a(More)
BACKGROUND Early stage lung cancer has a variable prognosis, and there are currently no markers that predict which patients will recur. This study examined the relation between tumor-regulatory T (Treg) cells and total tumor-infiltrating T-cell lymphocytes (TIL) to determine whether they correlated with recurrence. METHODS The authors reviewed all(More)
OBJECTIVE Advantages of thoracoscopic lobectomy for early stage non-small cell lung cancer (NSCLC), as compared with lobectomy by conventional thoracotomy, include less postoperative pain and shorter length of hospitalization. The outcomes after thoracoscopic lobectomy in patients with more complex pulmonary conditions are analyzed to determine safety,(More)
BACKGROUND This study was undertaken to review a large series of resections of colorectal pulmonary metastases in the era of modern chemotherapy. METHODS A retrospective chart review of prospectively maintained thoracic surgery databases identified 378 patients who underwent pulmonary resection for colorectal cancer metastases with curative intent from(More)
PURPOSE To determine in a randomized prospective multi-institutional trial whether the addition of tumor necrosis factor alpha (TNF-alpha) to a melphalan-based hyperthermic isolated limb perfusion (HILP) treatment would improve the complete response rate for locally advanced extremity melanoma. PATIENTS AND METHODS Patients with locally advanced extremity(More)
OBJECTIVES The outcomes of patients with metastatic melanoma are poor. Although prognostic models have been developed to predict the occurrence of pulmonary metastasis from cutaneous melanoma, few data exist to define the outcomes of these patients once metastasis has occurred. The objective of this study was to discriminate predictors of survival for(More)
BACKGROUND Post-sternotomy mediastinitis reduces survival after cardiac surgery, potentially further affected by details of mediastinal vascularized flap reconstruction. The aim of this study was to evaluate survival after different methods for sternal reconstruction in mediastinitis. METHODS Two hundred twenty-two adult cardiac surgery patients with(More)
BACKGROUND Clinical success with modern heart transplantation (HT) has led to the development of an alternate list (AL) HT strategy, matching marginal cardiac allografts with recipients who do not meet standard criteria for HT. Marginal allografts may be at an increased risk for primary graft dysfunction (PGD), the leading cause of early mortality after(More)
BACKGROUND We conducted a study of patients who underwent anatomic resection with adjuvant chemotherapy to determine if thoracoscopic lobectomy enables more effective administration of adjuvant chemotherapy than lobectomy by thoracotomy. METHODS We reviewed the outcomes of 100 consecutive patients with non-small cell lung cancer (NSCLC) who underwent(More)
