![]() Otherwise, men with average risk should begin screening at age 50, the society suggests.ĭ'Amico and his colleagues analyzed data on almost 950 men between the ages of 62 and 76 who underwent either surgical or radiation treatment for prostate cancer at one of four hospitals between 19.Īt the time of diagnosis, all the patients displayed at least one indicator of aggressive prostate cancer: either a high absolute PSA reading poor biopsy results regarding the health of prostate tissue at the cellular level an advanced stage tumor or a notable jump in their PSA velocity in the year prior to treatment.Īlmost 70 percent of the patients had one of these high-risk markers at diagnosis, the researchers noted. The organization currently recommends that men at high risk for prostate cancer, which includes blacks and men with a family or personal history of the disease, should begin undergoing yearly digital rectal exams and PSA blood tests between the ages of 40 and 45. This year nearly 220,000 new cases of the disease are expected to be diagnosed, and about 27,000 men will die of the disease. The American Cancer Society notes that, outside of skin cancer, prostate cancer is the most common form of cancer diagnosed among American men. "It all depends on where it's been and where it's going," he said. D'Amico, the chair of genitourinary radiation oncology at Brigham and Women's Hospital and professor of radiation oncology at Harvard Medical School in Boston. "We know that, without any other factors, PSA velocity is a very good predictor of prognosis," said study leady author Dr. Reporting in the July 1 issue of Cancer, the authors say that an increase by two points or more of PSA over one year is a better predictor of death from prostate cancer than either a one-time "snapshot" of PSA levels at diagnosis, or a doctor's assessment of the stage of cancer prior to treatment. ![]() TUESDAY, May 29 (HealthDay News) - A rapid rise in blood levels of prostate specific antigen (PSA) over the course of a year - a diagnostic indicator known as "PSA velocity"- is the single most important marker for a particularly aggressive and deadly form of prostate cancer, new research suggests. ![]()
