Predictive models of toxicity with external radiotherapy for prostate cancer

“…In the recent years, there has been growing interest among radiation oncologists in developing predictive models of practical utility (ie, probability formulas and nomograms) in prostate cancer irradiation. Nearly all have been focused on disease control prediction (to help physicians and to counsel patients in the decision‐making process),1‐5 on the prediction of pathologic extension (to select anatomic target[s] for external beam radiation therapy [EBRT]6‐8), on supporting radiation oncologists in the decision of dose levels to be delivered,9 and on helping clinicians choose the appropriate combination of therapies both in standard practice (ie, neoadjuvant/adjuvant androgen suppression)3, 10 and in experimental clinical trials (ie, chemotherapy for high‐risk patients11 as in the Radiation Therapy Oncology Group [RTOG] 0521 study and in the Dana‐Farber Cancer Institute Protocol 05‐043).…”
