The origins and early history of quantum stochastic calculus are surveyed, with emphasis on the collaboration between K R Parthasarathy and the author. 1. Introduction. I rst met Partha in 1971 when he was at She¢ eld University. The occasion was a regional meeting of the UK Royal Statistical Society in Leeds. Partha gave what to me was a brilliantly clear exposition of quantum probability as ...
We analyse an argument of Deutsch, which purports to show that the deterministic part of classical quantum theory together with deterministic axioms of classical decision theory, together imply that a rational decision maker behaves as if the probabilistic part of quantum theory (Born’s law) is true. We uncover two missing assumptions in the argument, and show that the argument also works for a...
PURPOSE Research of predictive factors of biochemical recurrence to guide the establishment of an adjuvant treatment after radical prostatectomy for cancer with positive surgical margins. METHODOLOGY A retrospective cohort of 1577 afro-caribbean patients undergoing radical prostatectomy operated between 1st January 2000 and 1st July 2013 was analyzed. In this cohort, 406 patients had positive...
PURPOSE Deoxyribonucleic acid ploidy correlates with the biological behavior of prostate carcinoma. However, the usefulness of ploidy on needle biopsies that show prostate cancer has not been established to our knowledge. MATERIALS AND METHODS We retrospectively determined ploidy on needle biopsies of 159 men with prostate carcinoma treated surgically at Johns Hopkins Hospital. Ploidy was det...
OBJECTIVE To update the 2007 Partin tables in a contemporary patient population. PATIENTS AND METHODS The study population consisted of 5,629 consecutive men who underwent RP and staging lymphadenectomy at the Johns Hopkins Hospital between January 1, 2006 and July 30, 2011 and met inclusion criteria. Polychotomous logistic regression analysis was used to predict the probability of each patho...
PURPOSE Gleason 6 (3+3) is the most commonly diagnosed prostate cancer among men with prostate specific antigen screening, the most histologically well differentiated and is associated with the most favorable prognosis. Despite its prevalence, considerable debate exists regarding the genetic features, clinical significance, natural history, metastatic potential and optimal management. MATERIA...
CONTEXT The Gleason grading system is one of the most powerful predictors of outcome in prostate cancer and a cornerstone in counseling and treating patients. Since its inception, it has undergone several modifications triggered by a change in clinical practice and a better understanding of the cancer's histologic spectrum and variants and their prognostic significance. OBJECTIVE To provide a...
Underestimation of Gleason score at prostate biopsy reflects sampling error in lower volume tumours.
OBJECTIVE • To determine the influence of tumour and prostate gland volumes on the underestimation of prostate cancer Gleason score in diagnostic core biopsies. PATIENTS AND METHODS • Patients undergoing radical prostatectomy with matched diagnostic biopsies were identified from a prospectively recorded database. • Tumour volumes were measured in serial whole-mount sections with image analysi...
