“Background and Objectives: We
compared clinical outcomes in patients who were treated with different chemotherapeutic regimens after resection of hepatic metastases from colorectal cancer (CRC).\n\nMethods: Between August 2001 and June 2008, 156 patients who entered into chemotherapy of adjuvant intent after hepatic metastasectomy were reviewed retrospectively.\n\nResults: Of the 156 patients, 58 patients were treated with oxaliplatin/fluoropyrimidines (group I), 48 with irinotecan/fluoropyrimidines (group II), and 50 with fluoropyrimidines alone (group III). In the univariate analysis, there was a marginally significant difference among the three groups with respect to the disease-free survival (DFS): 23.4 months in group I, 14.1 months in group II, mTOR inhibitor and 16.3 months in group III, P = 0.088). Group I showed better DFS when compared to the other two groups combined (group II and III) (P = 0.03). Multivariable analysis showed a marginally significant gain in the DFS for group I (P = 0.068). Multiple metastases (P = 0.045) and positive resection margin (P = 0.003) were significantly associated
with poorer DFS.\n\nConclusion: Postoperative combination chemotherapy of oxaliplatin/fluoropyrimidines seemed to show better DFS when compared to fluoropyrimidine monotherapy or irinotecan-based combination in patients who underwent liver metastasectomy.

“Background: Restoration of blood flow to an acutely ischemic FHPI mw limb can trigger systemic inflammation. We investigated whether antithrombin III (AT-III) exerts a protective action against remote lung and myocardial injury in an experimental animal model of lower-limb ischemiae-reperfusion.\n\nMethods: Ischemia was induced by lower-limb arterial occlusion for 6 hours in 60 male Wistar rats. Animals were divided into those receiving AT-III (dose, 250 mg/kg) 30 minutes before the reperfusion (group A, n = 30) and those receiving placebo (group B, n = 30). Animals were then sacrificed, and lung and myocardial
tissue samples were taken at baseline, 30 minutes, and 4 hours after reperfusion. Levels of malondialdehyde (MDA), a compound used as indirect index of oxygen free radicals, were estimated in lung and myocardium, and the two groups were compared at different time BKM120 chemical structure points using the independent sample t test.\n\nResults: Animals administered AT-III had significantly lower levels of lung MDA compared with the placebo group at baseline and at 30 minutes, but not at 4 hours (P = 0.001, P = 0.01, and P = 0.9, respectively), indicating a protective action of AT-III against remote lung injury early in the reperfusion phase. With regard to myocardial MDA levels, no statistically significant differences existed between the AT-III and placebo groups at baseline, at 30 minutes, and at 4 hours (P = 0.07, P = 0.
