This retrospective study included 21 patients who underwent surgical resection for HCC disease recurrence

after RFA. Clinicopathological findings, including patterns of recurrence, immunohistochemical expression of proliferation markers (Ki-67 and p27Kip1) and survival outcome were PI3K inhibitor assessed. The median time interval after RFA until the diagnosis of intrahepatic and/or extrahepatic tumor progression was 12 months (range, 3–84). Radical surgical resection was attempted for intrahepatic local recurrence in 16 patients (18 lesions), for peritoneal dissemination in four, for lymph node metastases in three and for adrenal metastasis in two. In 14 of the 21 (67%) patients, the recurrent HCC were histologically diagnosed as of poorly differentiated type. Their average Ki-67 and p27Kip1 labeling indices were significantly higher (P = 0.020) and lower (P < 0.001), respectively, compared with values for the 108 HCC surgically resected at the initial treatment. Portal involvement was significantly higher (P = 0.01) in recurrent tumors after RFA (72%) than in HCC surgically resected at the initial treatment (43%). The mortality rate of salvage surgery was 0%, with cumulative survival rates at 1 and 3 years of 58.9% and 35.7%, respectively.

The recurrent tumors after RFA have characteristics of poor differentiation degree and abnormalities in cell-cycle regulators and are associated with aggressive vascular selleck screening library invasiveness. “
“In the present study, the potential benefits of oral carnitine

in preventing antituberculosis drug-induced hepatotoxicity (ATDH) were evaluated. Fifty-four patients in the carnitine and 62 see more patients in the placebo group completed the study. The carnitine group received 1000 mg oral carnitine solution twice daily for 4 weeks. The placebo group received 10 mL of oral placebo solution twice daily for 4 weeks. ATDH was defined as an increase in the serum level of aspartate aminotransferase or alanine aminotransferase greater than three or five times of the upper limit of normal with or without clinical symptoms of hepatotoxicity, respectively. During the study period, 29 (25%) patients experienced ATDH. Among these patients, nine (16.7%) and 20 (32.3%) were in the carnitine and placebo groups, respectively (P = 0.049). Based on multivariate logistic regression model, age over 35 years old (odds ratio [OR] = 7.01, P = 0.002), human immunodeficiency virus infection (OR = 40.4, P < 0.001), diabetes mellitus (OR = 37.6, P = 0.001), and placebo treatment (OR = 0.1, P = 0.01) were identified as predisposing factors for ATDH. Results of our preliminary clinical trial suggested that cotreatment with 2000 mg oral L-carnitine solution daily for 4 weeks significantly decreased the rate of ATDH. "
