RESUMO
Advancements in endovascular therapy have made it increasingly available for patients with complex cases but not without complications. Unintentional coverage of the renal arteries is a rare occurrence during endovascular aortic aneurysm repair. Given the potentially devastating repercussions, it is important that surgeons understand the suitability and the risks and benefits of the available revascularization options. We have described two cases of unintentional renal coverage, with subsequent successful bailout via direct manipulation of the stent-graft with a steerable sheath. We also conducted a review of the reported data, discussed the breadth of management options and their technical aspects, and provided several distinct solutions.
RESUMO
BACKGROUND: As Canada's population ages, incidence of gastric cancer in elderly patients is increasing. There is little data on treatment and outcomes of gastric cancer in patients older than age 75. This study aimed to assess treatment patterns and outcomes of non-metastatic elderly gastric cancer patients in Alberta, Canada. METHODS: Records of elderly patients (age 75 or older) diagnosed with localized gastric or gastroesophageal junction cancer between 2007 and 2012 who received curative intent surgery were retrospectively collected from the Alberta Cancer Registry. A chart review was completed to gather demographics; treatment details of surgery, chemotherapy, and radiotherapy; and outcomes. Descriptive analyses were undertaken, and variables were compared with parametric and nonparametric tests where appropriate. RESULTS: 130 predominantly male (69%) patients, median age 80 (range 75-96) were included. 17 patients (13%) received multimodality therapy. 115 (88.5%) had negative margins on final pathology. Mean lymph nodes retrieved were 16 (range 0-43). 46 surgical patients (35.4%) had grade II or higher complications. 13 patients had a perioperative death (Clavien grade V). Four (3.1%) patients completed perioperative chemotherapy, and 13 (10%) patients had adjuvant chemo/radiotherapy. 50 (38.5%) recurred at median 13 months, while 80 (61.5%) did not have a recurrence of their cancer at any time during follow up. The 5 year DFS for the surgery only group was 67.3% and multimodality group was 52.9% (p = 0.25). The 5 year OS for the surgery only group was 38.9% and multimodality group was 47.1% (p = 0.52). CONCLUSIONS: Our findings suggest that even with surgery alone, selected elderly patients with non-metastatic gastric cancer can obtain apparent prolonged survival, despite not receiving standard of care multimodality therapy. More studies are needed to optimise elderly patients' treatment selection.
