A statistical study of the Johns Hopkins University's Brady Institute for urinary studies showed that for adult men, those who are not aggressive prostate cancer and prostate cancer who are monitored by the urinary tract, the development of the prostate cancer and the probability of dying from cancer are very low. The study analyzed 1298 adult male patients who participated in the "prostate cancer surveillance program" for the past 20 years, and only two died of prostate cancer and three prostate cancer development.
Ballentine Carter H., a leader of the study, and a professor of adult urinary tract, pointed out that the death rate was lower in patients with prostate cancer who were treated with non aggressive prostate cancer and long term monitoring. Although the patient of the prostate cancer initiative monitoring program was "carefully chosen", but if you continue this research, Professor Carter believes the results will not be too big changes. The reason is that two of the three deaths in the dead have other reasons. At the same time, Professor Carter also noted that the study was done in the Caucasian population (white), may not apply to blacks, because the black cancer is often malignant cancer.
The study, published online in the of Clinical Oncology Journal, began in 1995, and patients who participated in the study were involved in the activity of the biopsy, judging by the extent of their aggressive prostate cancer, until the age of 75 years. In the living tissue examination, the doctor will also detect prostate cancer marker gene PTEN expression level of the corresponding protein, to be used as an indicator of tumor aggressiveness. Of the 1298 adult men who had participated in the program, 47 died, 16 died from other causes (mostly cardiovascular disease), and two of them died after 49 years of monitoring prostate cancer, while others were involved in the project to check prostate cancer and died 15 months after the diagnosis. After 10 years and 15 years of prostate cancer surveillance, 99.9% of patients survived, and 94% of patients did not suffer from malignant prostate cancer.
The development of prostate cancer is very long, after 20 years of development, patients tend to die. However, it is not to carry out surgical intervention, or simply monitor the disease without radiation therapy, or there is a dispute. This study points out that the non aggressive prostate cancer in the long term monitoring after becoming malignant prostate cancer and the probability of death is very low, for mild prostate cancer patients, active monitoring effect is better than the effect of surgery.
Taking into account that about 30-304% of adult men in the United States should be involved in prostate cancer surveillance, and in some countries in northern Europe, the number is likely to reach 80%, and the monitoring program has a great advantage in the treatment of prostate cancer, with less cost. A recent survey shows that about 20% of patients with prostate cancer treated in the five years after treatment, because the cost is too high to bear.
In the future, by improving the means of detection and imaging technology, researchers can distinguish between patients who do not need to treat prostate cancer, but only through regular detection of prostate cancer aggressiveness can achieve the effect of treatment and control. And now the "active surveillance" program has been considered as the best guide for cancer related doctors in the United States. If you really do not have surgery can cure prostate cancer, so this is a new hope for the majority of adult men.
