Prostate cancer is the most commonly diagnosed non-cutaneous cancer and the third most common cause of death from cancer in males in the US. An increasing life expectancy in male population and increasing use of prostatespecific antigen (PSA) for early detection of the disease are probably the two main factors accounting for higher detection rate. The DRE is still the basis in the suspicion of ...

We evaluated the clinicopathological features and prognosis of 29 cases of prostate ductal carcinoma was considered to be an aggressive subtype of prostate acinar carcinoma. We selected 29 cases who were diagnosed prostate ductal carcinoma and had a radical prostatectomy (RP). The acinar group (n = 116) was selected among 3,980 patients who underwent a prostatectomy. The acinar group was matche...

We have shown previously that genistein, the major isoflavone in soybean, inhibited the growth of human prostate cancer cells in vitro by affecting the cell cycle and inducing apoptosis. To augment the effect of radiation for prostate carcinoma, we have now tested the combination of genistein with photon and neutron radiation on prostate carcinoma cells in vitro. The effects of photon or neutro...

Elucidation of the mechanisms of hormone-independent metastatic prostate cancer remains a significant and highly relevant challenge. We report here that hormone-refractory human prostate carcinoma growing orthotopically efficiently deliver viable metastatic cells in the host circulation. This is in contrast to the ectopic tumors of the same lineage, which do not deliver live cells into the circ...

Foamy gland carcinoma is a variant of prostatic acinar adenocarcinoma characterized by abundant, foamy cytoplasm, frequently showing small, pyknotic nuclei. The incidence and Gleason grade of foamy gland carcinoma in a large prostate needle biopsy series have not been established. Foamy gland carcinoma may be deceptively benign appearing and missed on needle biopsy. Immunohistochemical staining...

Epidemiological studies provided the first evidence that COX may be involved in the pathogenesis of cancer. In the process of carcinogenesis and in the route of intracellular signalling during carcinogenesis, COX-2 expression may be a universal phenomenon. In general, COX-2 is up-regulated throughout the tumorigenic process, from early hyperplasia to metastatic disease. COX-2 has been reported ...

An 87-year-old-man with prostate-cancer-stage-T1c-Gleason-6 treated with radiotherapy in 1996, recurrent prostate cancer treated with leuprolide hormonal therapy in 2009, and bladder-urothelial-carcinoma in situ treated with Bacillus-Calmette-Guerin and adriamycin in 2010, presented in 2015 with painless, bright red blood per rectum coating stools daily for 5 mo. Rectal examination revealed bri...

New molecular factors have been characterized that are associated with the prognosis of prostate carcinoma patients, including p53 status and angiogenesis. We reported recently that mutant p53 (mp53) was associated with decreased expression of an endogenous inhibitor of angiogenesis, thrombospondin-1 (TSP-1), and increased microvessel density in melanoma and breast cancer. In this study, we per...

Carcinoma of the prostate (PCa) is one of the most commonly diagnosed malignancy afflicting the men which is a leading cause of carcinoma related mortality in men. Effect of trace elements like zinc and copper has been studied extensively in the recent years to evaluate their role in pathogenesis of various neoplasms including prostate carcinoma. The objective of this study was to seek an assoc...

The enzyme activities of Lactate dehydrogenase (LDH). prostate fluid LDH isoenzymes phosphohexose isomerase (PHI), Aldolase (ALD) and Hexokinase (HK) were determined in the sera of 77 samples of males. There were 12 cases of carcinoma prostate with metastases, 15 without metastases, 25 with benign prostatic hypertrophy and 25 nontumor. The enzyme activities of nontumor and benign group were sta...
