Background/AimsRecurrence after hepatic resection is one of the most important factors impacting the prognosis and survival of patients with hepatocellular carcinoma (HCC). We identified prognostic factors affecting overall survival (OS) and disease-free survival (DFS) in patients with HCC after hepatic resection.MethodsThis study was of a retrospective cohort design, and 126 patients who underwent hepatic resection for HCC at Gachon University Gil Medical Center between January 2005 and December 2010 were enrolled. Various clinical, laboratory, and pathological data were evaluated to determine the prognostic factors affecting OS and DFS.ResultsTwo- and 4-year OS and 2- and 4-year DFS were 78.1% and 65% and 51.1% and 26.6%, respectively. In a multivariate analysis, preoperative α-fetoprotein (> 400 ng/mL), tumor size (≥ 5 cm), multiple tumors (two or more nodules), presence of portal vein invasion, modified Union for International Cancer Control (UICC) stage III/IV, and Barcelona Clinic Liver Cancer (BCLC) stage B/C were independent prognostic factors affecting a shorter OS. In the multivariate analysis, presence of microvascular invasion, modified UICC stage III/IV, and BCLC stage B/C were independent prognostic factors for a shorter DFS.ConclusionsThe presence of vascular invasion was an independent poor prognostic factor for OS and DFS in patients with HCC after hepatic resection. Thus, close postoperative surveillance for early detection of recurrence and additional treatments are urgently needed in patients with vascular invasion after hepatic resection.
Group B streptococcus (Streptococcus agalactiae, GBS), a primary pathogen in postpartum infection, has rarely been reported in psoas abscess. Primary proas abscess occurs less frequently than secondary abscess, which originates from infections of adjacent organs, such as intraabdominal infection, osteomyelitis, perirenal abscess, and retroperitoneal hematomas. We describe a case of primary psoas abscess caused by GBS. A 44-year-old woman with type 2 diabetes mellitus presented with left flank pain, intermittent fever, dysuria, and discomfort during walking. Abdominal CT showed multiseptated cystic mass in wide areas of the retroperitoneal space. Pus culture showed Streptococcus agalactiae. The patient responded to penicillin G treatment for 3 weeks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
