Glen Tisman, MD: Nomograms – Prediction of Effectiveness of 3D Conformal External Beam Radiation Therapy

Fri 31 Aug 2012

Nomogram 5 Prediction of Effectiveness of 3D Conformal External Beam Radiation Therapy Kattan is a very prolific researcher and has developed many nomograms for use in many different cancers, including many dealing with prostate cancer. Nomogram 5 was created for predicting the probability that a patient will develop metastasis within five years after three-dimensional conformalRead More ›

Glen Tisman, MD: Nomograms – Predicting Bone Scan Positivity (tumor spread to bone)

Tue 31 Aug 2010

Nomogram 9 Predicting Bone Scan Positivity (tumor spread to bone) Physicians often order periodic bone scans to check for metastases in patients with an increasing PSA, and a biochemical recurrence after radical prostatectomy, but most scans negative. A group of physicians from Memorial Sloan Kettering Hospital in Manhattan, NY studied patient characteristics in an attemptRead More ›

Glen Tisman, MD: Nomograms – Predicting Latent or Indolent Tumors of Low Biological Aggressiveness

Tue 31 Aug 2010

Nomogram 4 Predicting Latent or Indolent Tumors of Low Biological Aggressiveness Men diagnosed with clinically localized prostate cancer have a number of treatment options available, including watchful waiting, radical prostatectomy, and radiation therapy. With the widespread use of PSA testing, prostate cancers are being diagnosed earlier in their natural history, with many tumors being smallRead More ›

Glen Tisman, MD: Nomograms – Predicting Success of Brachytherapy

Tue 31 Aug 2010

  Nomogram 6 Predicting Success of Brachytherapy Kevin Slawin from Baylor College of Medicine collaborated with Michael Kattan and Christopher DiBlasio6 to develop Nomogram 6, which predicts the success of brachytherapy (seeds) for treating prostate cancer patients. This tool predicts the possibility of successful treatment for the patient based on factors such as PSA levels,Read More ›

Glen Tisman, MD: Nomograms – Prediction of Lymph Node Involvement with Tumor

Tue 31 Aug 2010

Nomogram 3 Prediction of Lymph Node Involvement with Tumor Caggianos et al3 developed nomograms for the preoperative prediction of lymph node metastases in patients with clinically localized prostate cancer. Their study was a retrospective, nonrandomized analysis of 7,014 patients treated with radical prostatectomy at six institutions between 1985 and 2000. Excluded were patients who hadRead More ›

Glen Tisman, MD: Nomograms – Probability of Seminal Vesicle Involvement

Tue 31 Aug 2010

Nomogram 2 Probability of Seminal Vesicle Involvement Koh et al2 presented Nomogram 2 which they used to predict the chance for seminal vesicle involvement (SVI). Patients with seminal vesicle involvement by tumor are considered by most urological surgeons to be inoperable because of a high chance of metastatic spread and so are better treated byRead More ›

Glen Tisman, MD: Nomograms – Probability of Extracapsular Extension

Tue 31 Aug 2010

Nomogram 1 Probability of Extracapsular Extension Nomogram 1 was constructed by Ohori et al.1 It attempts to predict the side specific probability of extracapsular extension of tumor (ECE) in radical prostatectomy (RP) specimens based on the clinical features of the cancer. Though extracapsular extension is not a contraindication to surgical removal of the gland orRead More ›

Glen Tisman, MD: Nomograms – Predicting Survival in Patients Resistant to Castration

Tue 31 Aug 2010

Nomograms 7 & 8 Predicting Survival in Patients Resistant to Castration Nomograms 7 and 8 were discussed in a publication by Matt Galsky and William Kelly.7 They are two point-based nomograms (Nomogram 7 by Smaletz et al and Nomogram 8 by Halabi et al). Both are based on pretreatment variables measured on a routine basisRead More ›

Using Nomograms to Predict Pathological Stage and Treatment Outcome for Patients with Prostate Cancer

Wed 30 Nov 2005

Edited from PCRI Insights November 2005 vol. 8 no. 4 By Glenn Tisman, MD Many times during the course of my oncology practice I have been made to feel like a referee of a dispute between the urological surgeon and the radiation therapist as they vie for center stage in the treatment of the prostateRead More ›
