A 78-year-old woman presented with an abdominal mass diagnosed by ultrasound and computed tomography. The patient underwent a laparotomy, during which a retroperitoneal tumor adherent to the cecum wall was identified. Microscopically, it showed spindle-cell proliferation in whorls, with low mitotic count (2 per 50 high-power fields) and was strongly positive for S-100 protein and vimentin. The final diagnosis was benign schwannoma of the cecum and no further treatment was required. Large intestine schwannomas are extremely rare tumors and only a few cases of schwannoma of the cecum have been reported to date.
o tratamento dos tumores anorretais avançados é desafiador, necessitando frequentemente de ressecções combinadas, como a cistectomia e sacrectomia, além de reconstruções complexas. A magnitude da cirurgia ainda carrega uma elevada taxa de morbidade, porém é um procedimento considerado seguro e factível, com uma baixa mortalidade e adequado controle locorregional tumoral quando realizado em centros de referência.
secondary endpoints are predicting factors for tumor recurrence and MJR. Results: Among the 121 TACE patients, 106 (87.6%) could be measured PR. The mean interval between TACE and hepatic resection was 33.1 days. 5 year DFS rates by PR status were as follows: 40.6% CPR, 43.7% MJR, and 49.0% MNR. There was also no significant difference in overall survival between 3 groups. Multivariate analyses revealed that microvascular invasion and capsular invasion (P = 0.001, hazard ratio [HR]: 13.7 and P = 0.031, HR: 2.3) were independent predictors for DFS. Multivariate analysis of the predictors of > 50% PR revealed that hepatitis B antigen positive and capsular invasion were independent factors. Conclusions: These data could reflect the PR after TACE for resectable HCC may not be useful for predicting recurrence of HCC after resection.
liver remnant would indicate the opposite. This chronic on acute liver failure may represent a new clinical entity where the options of treatment need to be explored.
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.
