Prostate Cancer Biopsy On Fat People are considered to be Misleading
People who telalu fat and excess weight who were diagnosed with prostate cancer by biopsy, are more likely to actually experience more cases of malignant disease compared to the results of biopsies obtained from healthy people lose weight, according to a study led by by a researcher at Duke University Medicl Centre
Findings suggests that misleading biopsy results may cause a lot of people who telalu fat and the extra weight they receive inadequate treatment or inappropriate so as not efficacious enough to eradicate the actual circumstances of their illness, says study leader Stephen Freedlnd, MD , an assistant professor in the Division of Urology and the Duke Prostate Centre.
"We already know that it is harder to diagnose prostate cancer in people who are too fat because they have a prostate specific antigen levels are lower, or PSA (Prostate-specific antigen), prostate cancer blood characteristic in common, and because prostate their larger size makes it more likely for a biopsy found cancer, "the researchers said. "These findings further suggest that we may fail to find even higher levels of disease in people who are too fat."
Pengeryian obtain a better relationship between biopsies and prostate cancer also may make it easier for physicians to improve patient treatment, said Freedland, who was also appointed as a surgeon at the Durham Veterans Affairs Medical Centre.
"If we can determine through additional biopsy that a man who is too fat or too excessive body weight has a malignant prostate cancer, then we can talk about whether the cancer should be treated with more than one way, such as combining hormonal therapy with radiation to reduce the spread of cancer and enlarge the possibility to recover, "So says Freedland. "We must remember that even if a biopsy is performed with both showing a low level in patients with cancer who are too fat, there is still no reasonable possibility that the patient suffered from high levels of disease."
The researchers from six universities publish the findings in the Journal of Urology in March 2007.
The research was funded by the Department of Veterans Affairs, the National Institutes of Health, the Georgia Cancer Coalition and The American Urological Association Foundation.
Prostate cancer is the most common type of cancer the second, after skin cancer in men in the United States. A man there has one of the six keungkinan to be diagnosed with prostate cancer at some time of his life, according to the Prostate Cancer Foundation. People who are too fat, who are diagnosed with the disease is 20 percent more likely to die from the disease compared with those who brtbobot healthy body.
Doctors typically conduct a biopsy when indicated by the presence of cancer screening tests, like blood test for PSA, or by the occasional discovery of digital rectal examination. To perform a biopsy, a doctor jabbed a needle into the prostate and take the tendon for the purpose of analysis.
In that study, researchers analyzed data from more that 1100 people had surgery between 1996 and 2005 to remove the prostate gland, a common treatment for prostate cancer. They compared the virulence of the attacks each patient's cancer as a requirement for the examination of samples obtained during diagnostic biopsy have a malignant disease found by microscopic examination of diseased prostate tissue taken when doing surgery.
People who are too fat, 89 percent more likely to have prostate cancer compared with people who are healthy body weight as indicated by biopsy. According to Freedland. People who have a Body Mass Index (BMI) greater than 30 is seen as people who are too overweight. BMI is a measure of weight adjusted for height of a person's body. In this scale, the size of five feet, 11 inches of body weight of more than 215 pounds, is a person who is too fat
The researchers also found that people who weigh too much but not too fat is 44 percent more likely to have a malignant cancer that attacks compared to Deng; of what is signaled by a biopsy. People who have a body mass index (BMI) between 25 and 29.9 is considered overweight badaan; person five feet tall and 11 inches that weigh more than 180 pounds including the excess weight.
Freedland says that this discrepancy is unclear, but may be associated with the fact that people are too fat and excess weight have a larger prostate size, which bsia means that the number of samples taken during biopsy usual is not enough to reveal the true status of the gland.
To help reduce the number of people who are so fat that his prostate cancer categorized inappropriately, physicians should perform a biopsy of the prostate gland more. Freedland argued.
"Performing more biopsy samples will make it easier to determine the malignancy of prostate cancer attacks and will allow a better treatment plan for a 'needs' of patients. "So says Freedland again.
