Objectives:To review the clinical outcome of locally advanced rectal cancer treated with neoadjuvant chemoradiation followed by definitive surgery with or without adjuvant chemotherapy and to elucidate the prognostic factors for treatment outcome.Methods: This historical cohort study was conducted at a tertiary public hospital in Hong Kong. All patients who had undergone neoadjuvant chemoradiation for locally advanced rectal cancer in our department from November 2005 to October 2014 were recruited. Local recurrence-free survival, distant metastasis-free survival, diseasefree survival, and overall survival of patients were documented.Results: A total of 135 patients who had received neoadjuvant chemoradiation during the study period were reviewed. There were 130 patients who had completed neoadjuvant chemoradiation and surgery. The median follow-up time was 35.1 months. The 3-and 5-year local recurrence-free survival, distant metastasis-free survival, diseasefree survival, as well as overall survival rates were 91.8% and 86.7%, 73.9% and 72.1%, 70.1% and 64.6%, as well as 86.5% and 68.4%, respectively. The rate of pathological complete response was 13.8%. The T and N downstaging rate was 49.2% and 63.1%, respectively. The rate of conversion from threatened circumferential resection margin to clearance of margin was 90.6%. Of the 42 cases that were initially Clinical outcome of neoadjuvant chemoradiation in locally advanced rectal cancer at a tertiary hospital
We report an unusual case of severe mechanical hemolysis after implantation of a 17-mm Rashkind patent ductus arteriosus occluder in a young adult female with a large ductus. The device failed with conservative management, including implantation of a second occluder, and surgery was required to close the ductus. This occluder may not be suitable for closure of a large patent ductus arteriosus.
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.
