Can MRI data improve decision-making about the need for a biopsy?

Last week we noted that adding MRI data to the Partin tables and to the Kattan/MSKCC nomograms did not seem to improve the accuracy of prognosis of outcomes after radical prostatectomy. … READ MORE …

New grade group system predicts risk for prostate cancer-specific mortality

According to a report on the Renal & Urology News web site this morning, a new paper about to be published on line in European Urology (by He et al.) has shown that the new ISUP staging system can be used to project risk for prostate cancer-specific mortality, “regardless of treatment received or clinical stage at diagnosis”. … READ MORE …

Predictive accuracy of the new ISUP grading system in a nationwide patient cohort

A paper in European Urology has provided us with additional early data on the applicability of the new ISUP grading system scheduled to replace the Gleason grading system over the next few years. … READ MORE …

Predicting sexual function after first-line treatment for prostate cancer

A newly published report in the Journal of the American Medical Association provides data (from two large cohorts of patients) on the quality of sexual function among men undergoing first-line treatment for localized prostate cancer. … READ MORE …

Risk stratification of men with high-risk prostate cancer prior to first-line surgery

A new French study has attempted to provide a better appreciation of the effect of predictive factors on the biochemical recurrence-free and overall survival of patients with high-risk prostate cancer after a radical prostatectomy (RP). … READ MORE …

The MSKCC-Malmö four-kallikrein model for prediction of prostate cancer risk

The collaborative research between the teams at Memorial Sloan-Kettering Cancer Center in New York and in Malmö in Sweden continues to  refine a model that may allow us to accurately predict which patients are at clinically significant risk for prostate cancer based solely on simple tests run on a single blood sample. … READ MORE …

Projection of 15-year prostate cancer-specific survival after radical prostatectomy

For several years we have been able to use the Kattan nomograms to project 5-, 7-, and 10-year recurrence-free survival before and after radical prostatectomy for localized prostate cancer, based on the patient’s age, stage, Gleason score, and other relevant data (associated with biopsy or surgical findings, as appropriate). … READ MORE …

Psychosocial distress at diagnosis and 12 months later

Every prostate cancer patient (and many patients subsequently found not to have prostate cancer) have been through the psychological and social distress associated with the risk of a diagnosis of prostate cancer. It’s no fun. … READ MORE …

Predicting risk for Gleason score upgrades in non-surgical patients

The ability to predict risk for Gleason score upgrading in patients who have any form of treatment other than radical prostatectomy can be important, because it may help treating physicians and their patients to optimize first-line therapy. … READ MORE …

Limited predictive accuracy of endorectal coil MRI

Patients believed to be at potential risk for prostate cancer that may extend outside the prostate itself — through extracapsular extension (ECE) or seminal vesicle invasion (SVI) — often undergo imaging studies in planning for their treatment. Endorectal coil magnetic resonance imaging (erMRI) as been a commonly used form of such imaging. … READ MORE …

Can the presence of hyaluronidase predict risk for progression?

A key goal of the prostate cancer research community has been the identification of markers that could help us to better identify patients at high risk for prostate cancer progression as early as possible in the disease process. It now appears that the presence of an enzyme called HYAL-1 hyaluronidase and hyaluronic acid staining in prostatectomy specimens may be able to do this. … READ MORE …

The Wednesday news report: March 25, 2009

We have separately addressed data from a 15-year follow-up of a population-based Swedish screening study. Other reports today deal with:

  • The impact of dietary and supplemental zinc on prostate cancer risk
  • Prediction of risk for loss/preservation of erectile function post- prostatectomy
  • Anti-androgen therapy and brachytherapy: options and outcomes … READ MORE ….

The accuracy of the the Kattan prostate nomogram prognostic data

Many clinicians and their patients use the so-called Kattan nomograms to help make decisions about outcomes following use of certain types of prostate cancer treatment. Apparently these prediction tools have also become known in at least some circles as “Prostagram” data. (This is the first time The “New” Prostate Cancer InfoLink has ever come across the use of this term.) … READ MORE …

Prediction of a persistently detectable PSA post-surgery

An Italian group has published an analysis of data from their surgical series suggesting that it is possible to predict the probability of a persistently detectable PSA post-surgery. … READ MORE …
