New Computer Model May Improve Prostate Cancer Diagnosis, Personalized Treatment
Detecting, diagnosing, and treating prostate cancer may become simpler following the development of a novel computer model that uses medical images to reproduce prostate cancer growth on the anatomy of a patient's prostate. The model, described in the paper "Tissue-scale, personalized modeling and simulation of prostate cancer growth," and published in the Proceeding of the National Academy of Sciences, may lead to better personalized treatment and prediction of each patient's clinical outcomes. "There is a lot of room for improvement in both the diagnosis and management of prostate cancer," study co-author Michael Scott, Brigham Young University professor of civil and environmental engineering, said in a press release. "We're using computer modeling to capture the behavior of prostate tumor growth, which will hopefully lead to minimally invasive predictive procedures which can be used in clinical practice," he said. Current medical practice requires men to undergo periodical screening for prostate cancer through PSA tests and digital rectal exams. If either test is positive, patients are asked to undergo a biopsy to detect cancerous cells and the aggressiveness of the tumor. But this often lead to patients being over- or under-treated. Although medical images obtained with MRI and computed tomographies are already used to complement prostate cancer screening techniques, the researchers believe the new model may help replace the invasive biopsie
