Stratification of Atypical Intraepithelial Prostatic Lesions Based on Basal Cell and Architectural Patterns.

CONCLUSIONS: Such stratification is of great clinical significance and instrumental to clinical patient management. It not only increases the predictability of AILs for iPCa but also accommodates a clinical scenario for lesions with features of intraductal carcinoma when iPCa is not found, particularly in biopsies.

Radioactive seeds implanted via ultrasound or computed tomography (CT) guidance are minimally invasive and facilitate quick recovery. Transrectal ultrasound-guided 125I seed implantation assisted by a transperineal plane template is standard for early-stage prostate carcinoma, with a hi...

A Streptomyces sp. (BRA-384) was selected among nine strains of bacteria isolated from the zoanthids Palythoa caribaeorum due to the high cytotoxic activity presented by its EtOAc extract (inhibitory concentration mean (IC50) of 2 ng mL-1) against colon cancer cell line. From the EtOAc extract of BRA-384 three new chemical entities (A6, A7 and A8) and one dextrorotatory chromomycin (A5), a promising class of anticancer compounds, were identified. The cytotoxicity of chromomycins A5 to A8 was tested against five tumor cell lines (HCT 116 (human colon adenocarcinoma), MCF-7 (human breast carcinoma), PC-3M (human metastatic p...

In conclusion, the majority of bladder cancers following brachytherapy in this cohort were of high grade and low stage at diagnosis, most of them demonstrating luminal immunophenotype. A significant number of variant histologies are seen, each demonstrating a specific immunophenotype.

Background: Mucinous prostate cancer (PCa) is an extremely rare form of prostate malignancy. To date, the limited knowledge of its biology and outcomes stems from mostly small, single institution experiences. We analyzed the Surveillance, Epidemiology, and End Results (SEER) database to explore the incidence and treatment of mucinous PCa together with its prognostic factors to gain relatively large and consolidated insights.Methods: Age-adjusted incidence (AAI) rates were evaluated over time. Propensity score matching (PSM) and Kaplan–Meier analyses were used to compare the prognosis between mucinous PCa and typical ...

ConclusionsAdjuvant chemotherapy in high-risk prostate cancer using docetaxel and prednisone did not lead to statistically significant improvement in PFS for the intention-to-treat population as a whole. The analysis was challenged by lower power due to accrual limitation. Subgroup analyses suggest potential benefit for patients with Gleason grade ≤7 and stage ≥ pT3b ( number NCT00132301).Patient summaryIn this randomized trial, we tested whether addition of chemotherapy to surgery for high-risk prostate cancer decreased the risk of prostate-specific antigen rise after surgery. We found no...

ConclusionPQS promoted cells apoptosis and inhibited the proliferation of DU145 cells, which suggests that PQS may be effective for treating PC. TMEM79 and ACOXL were expressed significantly higher in PNT2 than in DU145 cells and could be novel biomarker candidates for PC diagnosis.Graphical abstract

Authors: Thaper D, Vahid S, Zoubeidi A Abstract Progression to the malignant state is fundamentally dependent on transcriptional regulation in cancer cells. Optimum abundance of cell cycle proteins, angiogenesis factors, immune evasion markers, etc. is needed for proliferation, metastasis or resistance to treatment. Therefore, dysregulation of transcription factors can compromise the normal prostate transcriptional network and contribute to malignant disease progression.The androgen receptor (AR) is considered to be a key transcription factor in prostate cancer (PCa) development and progression. Consequently, andro...

Authors: Nicholas TR, Strittmatter BG, Hollenhorst PC Abstract Prostate cancer is unique among carcinomas in that a fusion gene created by a chromosomal rearrangement is a common driver of the disease. The TMPRSS2/ERG rearrangement drives aberrant expression of the ETS family transcription factor ERG in 50% of prostate tumors. Similar rearrangements promote aberrant expression of the ETS family transcription factors ETV1 and ETV4 in another 10% of cases. Together, these three ETS factors are thought to promote tumorigenesis in the majority of prostate cancers. A goal of precision medicine is to be able to apply tar...
