Pure small cell carcinoma of the prostate is extremely rare. When it does occur, it is usually in concordance with prostatic adenocarcinoma. Early diagnosis is difficult as the carcinoma tends to spread early to visceral organs without concordant elevation of prostate-specific antigen (PSA). Because this condition is rare, no standard treatment regimen has been established, and the overall prog...

We analyzed expression status of the recently identified tumor suppressor geneRASSF1A in primary prostate carcinomas and in prostate cell lines. We found complete methylation of the RASSF1A promoter in 63% of primary microdissected prostate carcinomas (7 of 11 samples). The remaining 4 samples (37%) were partially methylated, possibly because of contamination with normal cells. No promoter meth...

PSMA PET is increasingly being used in imaging of recurrent prostate carcinoma. A case with suspected recurrent Prostate carcinoma (PCa), raised PSA (Prostate specific antigen) and suspected spinal metastases was referred for whole body Ga-68-PSMA PET/MRI. The study revealed PSMA avid recurrent prostate mass and extensive osseous metastases. Abnormal PSMA uptake in the thyroid gland prompted US...

The occurrence of small cell carcinoma in the urinary bladder and prostate is rare. Only a few reports on the cytological features of small cell carcinoma of the urinary bladder in the urine specimen have been documented and, moreover, the urinary cytological features of prostate small cell carcinoma have been rarely reported. In this study, we analyzed the cytological features of four cases of...

OBJECTIVES A subset of prostate carcinomas is composed predominantly, even exclusively, of neuroendocrine (NE) cells. In this report, we sought to characterize the gene expression profile of a prostate small cell NE carcinoma by assessing the diversity and abundance of transcripts in the LuCaP 49 prostate small cell carcinoma xenograft. METHODS We constructed a cDNA library (PRCA3) from the L...

Adenocarcinoma of prostate with mucinous differentiation arising in the male urethra is extremely rare, with only 21 cases reported in the previous literature. A diagnosis of mucin-producing urothelial carcinoma of the prostate is based on the pathology, immunohistochemistry, and clinical examination by excluding the secondary adenocarcinoma of the prostate. We present a case of unexpected muci...

INTRODUCTION Small cell carcinoma of the prostate is a very rare and aggressive type of prostatic cancer. Most cases are diagnosed at advanced stage due to early metastasis. The bones, liver, regional and distant lymph nodes are the most common sites of metastasis of small cell carcinoma of the prostate. Skin metastasis of small cell carcinoma of the prostate is a very rare entity due to the un...

BACKGROUND It is important for clinicians, researchers, and others who shape public health policy to understand the demographic correlates and psychologic factors that drive health behaviors, such as screening for early detection of cancer, particularly among individuals at high risk for developing the disease. METHODS One-hundred eleven men whose brothers were diagnosed with prostate carcino...

As number of cancer patients increasing, the chemotherapy treatments are also increasing. This analysis aims to provide a cutting-edge outline antineoplastic medications extracted from streptomyces. Streptomyces main source antibiotic production. Antineoplastic moderate pace tumor development and postpone metastasis. The utilization performance methods discussed, with focus on drugs. produces c...

BACKGROUND Small cell carcinoma of the prostate is an uncommon neoplasm, the origin of which has been controversial. To address this, we performed transcriptome profiling and TP53 sequencing of concurrent small cell and prostatic adenocarcinoma to determine the relationship between these entities. METHODS We identified an unusual case of primary prostate cancer that contained adjacent acinar ...
