PURPOSE To determine role of surgical intervention for Recurrent Pyogenic Cholangitis with hepatolithiasis at a North American hepatobiliary center. METHODS Retrospective analysis of 42 patients presenting between 1986 and 2005. RESULTS Mean age is 54.3 years (24-87). Twenty-seven patients (64%) underwent surgery, after unsuccessful endoscopic(More)
BACKGROUND Patients with hepatic and pulmonary metastases from colorectal cancer (CRC) may benefit from aggressive surgical therapy. We examined the longterm outcomes of patients who underwent both lung and liver resections for colorectal metastases over a 10-year period. STUDY DESIGN Four hundred twenty-three hepatectomies were performed for metastatic(More)
Adenocarcinoma of the pancreas is a significant cause of cancer mortality, and up to 10 % of cases appear to be familial. Heritable genomic copy number variants (CNVs) can modulate gene expression and predispose to disease. Here, we identify candidate predisposition genes for familial pancreatic cancer (FPC) by analyzing germline losses or gains present in(More)
Familial colorectal cancer (CRC) accounts for 10% to 20% of all cases of CRC. Two major autosomal dominant forms of heritable CRC are familial adenomatous polyposis (FAP) and Lynch syndrome (also known as hereditary nonpolyposis colorectal cancer). Along with the risk for CRC, both syndromes are associated with elevated risk for other tumors. Improved(More)
BACKGROUND Pancreatic adenocarcinoma is the fourth leading cause of cancer death. METHODS A prospective cohort study was undertaken between 2003 and 2011 at a tertiary care centre in Toronto, Canada. Two hundred and sixty-two subjects were enrolled based on an elevated estimated lifetime risk for pancreatic cancer due to known genetic mutations and/or(More)
Essiac is a popular complementary and alternative medicine (CAM) that is utilized by many cancer patients in North America. Much anecdotal reporting exists about its cancer-fighting qualities, but so far no clinical trials have been preformed to validate those claims. We describe here the case of a 64-year-old man whose hormone-refractory prostate cancer(More)
BACKGROUND The value of resection for locally recurrent rectal cancer (LRRC) remains controversial. We analyzed outcomes of an aggressive approach to resection of LRRC. METHODS We conducted a retrospective chart review of 52 consecutive patients who underwent resection of LRRC from September 1997 through August 2005. Overall and disease-free survival (OS,(More)
Although the association of germline BRCA2 mutations with pancreatic adenocarcinoma is well established, the role of BRCA1 mutations is less clear. We hypothesized that the loss of heterozygosity at the BRCA1 locus occurs in pancreatic cancers of germline BRCA1 mutation carriers, acting as a "second-hit" event contributing to pancreatic tumorigenesis. Seven(More)
PURPOSE Ulcerative colitis is a risk factor for colorectal cancer. Restorative proctocolectomy with ileal pouch-anal anastomosis is a standard surgical management of patients with ulcerative colitis who have cancer or dysplasia, but the oncologic risk of stapled anastomosis vs mucosectomy with handsewn anastomosis is debated. We compare the risk of new(More)
This study examined adult vaccination rates in Metropolitan Toronto/Peel Region following the implementation of publicly funded adult pneumococcal and universal influenza vaccination programs in Ontario. Community-living adults eligible for pneumococcal vaccines were surveyed regarding vaccination rates, and factors potentially associated with vaccination.(More)
