PURPOSE We have shown previously that oral feeding of green tea polyphenols (GTP) to transgenic adenocarcinoma of the mouse prostate mice in a purely chemopreventive setting significantly inhibits prostate cancer development. To translate this to a human situation, the present study was designed to identify the stage of prostate cancer that is most vulnerable to chemopreventive intervention by ...

Background: Prostatic adenocarcinoma by Prosate cancer (PCa) is the most prevalent cancer and the second cause of cancer-related death among men in the Western world. Human papilloma virus (HPV) may be considered as a preventable risk factor. In this study, we assessed the frequencies of HPV infection in prostatic adenocarcinoma and benign prostatic hyperplasia (BPH) cases in Northeast Mexico. ...

One of the major diagnostic challenges in prostate needle biopsy interpretation is definitive establishment of a malignant diagnosis based on a minimal or limited amount of carcinoma in needle biopsy tissue. Major and minor diagnostic criteria should be used for interpretation of small foci of carcinoma. The constellation of findings and a combination of the major and minor diagnostic criteria ...

Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tom...

We report a case of prostatic carcinoma with testicular metastasis, which mimicked malignant lymphoma of the testis. The patient was a 71 year-old man with a history of prostate adenocarcinoma of Gleason score 9 (4+5) diagnosed in 2001 for which he received hormonal therapy. Four years later, the patient developed multiple osteoblastic bone metastases. Radiotherapy of the bone metastases was gi...

OBJECTIVES Prostate cancer tends to spread to regional lymph nodes and bone, and, to a lesser degree, to lung, liver, and brain. Metastases in other locations are exceptional. To review the frequency and clinical characteristics of metastasis to subcutaneous cellular tissue in adenocarcinoma of the prostate. METHODS The case of a 71-year-old man diagnosed of adenocarcinoma of the prostate is ...

Prostate cancer is relatively unique to man. There is no naturally occurring prostate cancer in the mouse. Pre-clinical studies involve the establishment of a genetically engineered mouse prostate cancer model with features close to those of the human situation. A new knock-in mouse adenocarcinoma prostate (KIMAP) model was established, which showed close-to-human kinetics of tumor development....

AIM To determine prostate carcinoma tumor volume in routine pathology practice by using prostate tissue density. METHODS Prostate tissue density was determined experimentally by using picnometry in 57 unfixed prostate tissue fragments of different size. The percentage of prostate involvement was converted to tumor volume using the equation V=m/rho (g/mL). Additionally, all tumor foci were out...

background: for the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, mrsi was used as a molecular imaging modality with mri and ct images. materials and methods: the images of 20 prostate cancer patients were used in this study. the mr and mrsi images were registered with ct ones using non-rigid registration technique. the ct based planning (bp), ct/mr...
