Probability of lymph node involvement in prostate cancer patients
Calculates the probability that prostate cancer has spread to the pelvic lymph nodes (c-index: 0.86). This model does not require information regarding the number of biopsy cores. 

Disqualifying treatments: This model does not apply to patients who underwent preoperative hormone- or radiation therapy for prostate cancer.

Conditional information


How this model should be used:
This model calculates the probability that prostate cancer has spread to the pelvic lymph nodes. The model does not apply to patients who underwent preoperative hormone- or radiation therapy for prostate cancer. 

Model performance: 
A validation was performed to assess the discriminative power of the model. On the website of the MSKCC, a c-index of 0.86 is reported. No specific details regarding the validation process are disclosed.

Alternative models: 
For cases in which the number of cores taken at biopsy is known, an alternative prediction model including this information is available, although addition of biopsy core information did not improve the discriminative power of the model (c-index 0.86 in both models).
