Set the problem Prostate cancer Pca is common in men over age of 65 the disease is occult. Most cases were detected accidentally by histopathological examination. In Vietnam the standard age rate in 2012 was 100000 people and queued the 10 th in cancer in men. Pca can be treated effectively if the disease is detected early. Therefore the finding of early detection methods accurate diagnosis proper assessment of histopathological lesions by a standard and a uniform classification is essential to the development of therapeutic approaches and prognosis of this disease. Several studies have shown that the RASSF1A gene methylation occurs at an early stage in the formation and progression of the Pca. Thus RASSF1A gene methylation marker is being considered to Pca. In Vietnam studies on DNA methylation in cancer have been carried out lately histopathological and immunohistochemistry studies of Pca according to the 2004 World Health Organization WHO classification of tumors of the prostate are lacking. Based on that we do the following a. Study on some histopathological features of prostate carcinoma at Military Hospital 103 according to the 2004 WHO classification. b. Determine the expression of .
