Enumerating pelvic recurrence following radical cystectomy for bladder cancer: A Canadian multi-institutional study.

Introduction: We aimed to enumerate the rate of pelvic recurrence following radical cystectomy at university-affiliated hospitals in Canada.

Methods: Canadian, university-affiliated hospitals were invited to participate. They were asked to identify the first 10 consecutive patients undergoing radical cystectomy starting January 1, 2005, who had urothelial carcinoma stages pT3/T4 N0-2 M0.

Remediation of residents in difficulty: a retrospective 10-year review of the experience of a postgraduate board of examiners.

Purpose: To determine, through a 10-year review, (1) the prevalence of residents in difficulty, (2) characteristics of these residents, (3) areas of residents' weakness, and (4) outcomes of residents who undergo remediation.

Method: A retrospective review of resident records for the University of Toronto Faculty of Medicine's (UT-FOM) Board of Examiners for Postgraduate Programs (BOE-PG) was done from July 1, 1999 to June 30, 2009 using predetermined data elements entered into a standardized form and analyzed for trends and significance. Outcomes for residents in difficulty were tracked through university registration systems and licensure databases.

Loss of cyclin-dependent kinase inhibitor p27Kip1 is a novel prognostic factor in localized human prostate adenocarcinoma.

p27Kip1 is a cyclin-dependent kinase inhibitor that negatively regulates cell proliferation by mediating cell cycle arrest in G1. This study was undertaken to assess the prognostic value of p27Kip1 in localized human prostate cancer. Archival material from 113 radical prostatectomy specimens obtained between 1985 and 1993 was stained immunohistochemically for p27Kip1 protein using a commercially available antibody.

Proliferative activity and p53 expression in adenoid cystic carcinoma of the breast.

Adenoid cystic carcinoma is a rare type of invasive breast carcinoma that has a good prognosis. We studied a series of four cases of adenoid cystic carcinoma in which we correlated the clinical and pathological features. The pathological features examined included light microscopy; electron microscopy; immunohistochemistry using antibodies to keratin, vimentin, S100 protein, actin, estrogen and progesterone receptors, and proliferation marker MiB-1, and p53 suppressor protein; image cytometric analysis for measurement of DNA ploidy; and molecular analysis using polymerase chain reaction single strand conformation polymorphism to assess point mutation of the p53 gene.
