Identification of candidate genes that may contribute to the metastasis of prostate cancer by bioinformatics analysis.

Identification of candidate genes that may contribute to the metastasis of prostate cancer by bioinformatics analysis. Oncol Lett. 2018 Jan;15(1):1220-1228 Authors: Liu L, Guo K, Liang Z, Li F, Wang H Abstract To screen for marker genes associated with to the metastasis of prostate cancer (PCa), in silico analysis of the Gene Expression Omnibus dataset GSE27616, which included 4 metastatic and 5 localized PCa tissue samples, was performed. Differentially expressed genes (DEGs) were identified. Their potential functions were identified by Gene Ontology and Kyoto Encyclopedia of Gene Genomes pathway enrichment analyses. Furthermore, protein-protein interaction (PPI) networks for DEGs were constructed using Cytoscape. Module analysis of the PPI networks was performed with Cluster ONE. A total of 561 DEGs were screened, including 208 upregulated and 353 downregulated genes. Proliferating cell nuclear antigen (PCNA) and cluster of differentiation 4 (CD4) exhibited the highest degrees of connectivity in the PPI networks for up- and down-regulated DEGs, respectively. The DEGs in module A, including CD58, 2, 4 and major histocompatibility complex, class II DP-β1 were enriched in 'cell adhesion molecules'. Anaphase promoting complex subunit 4, cell division cycle 20 and cell division cycle 16 in module B were primarily enriched in 'cell cycle'. The DEGs, including CD4, PCNA and baculoviral IAP repeat containing 5, may have critical roles in PCa metastasis and...

CONCLUSIONS: Afro-Caribbean populations in French West Indies share the same major clinical and pathological risk factors of BCR after RP identified in other ethnic groups. Perioperative blood loss appears to be an additional and independent predictive factor of BCR. LEVEL OF PROOF: 4. PMID: 29789237 [PubMed - as supplied by publisher]

CONCLUSION: A reduction of LUTS is observed in patients with locally advanced or metastatic prostate cancer treated with triptorelin in routine practice. This is in agreement with similar observational studies of triptorelin conducted in other countries. LEVEL OF PROOF: 4. PMID: 29789236 [PubMed - as supplied by publisher]

CONCLUSION: Mp-MRI is a useful exam for selecting patients eligible for AS even if the situation remains unclear after prostate biopsies including targeted biopsies. Upon confirmation by further studies, mp-MRI should be considered as an independent criterion before entering an AS program. LEVEL OF EVIDENCE: 4. PMID: 29789235 [PubMed - as supplied by publisher]

CONCLUSIONS: In this study obese men do not appear to have a significant increase in risk of PSMs at RP compared to lean and overweight men when operated by a minimally invasive approach. The magnified vision and increased access to the pelvis allowed by a laparoscopic and robotic-assisted approach may be accountable for our findings. Larger studies are needed to validate our results.

The favorable outcome of the phase 3, ALSYMPCA (Alpharadin in Symptomatic Prostate Cancer Patients) trial has highlighted the use of -emitting radionuclides for therapy [1]. In this context, 223Ra, a calcium mimetic, was used in the treatment of patients with castration-resistant prostate cancer and bone metastases. Although this treatment exploits the natural accumulation of 223Ra in areas of increased bone turnover in bone metastases, active targeting of cancer cells or tumor vasculature can also be achieved.

We read with interest the phase III randomized trial by T øndel and colleagues [1] comparing weekly portal imaging and daily CBCT. Specifically, two strategies of IGRT were compared, either daily control to correct for both systematic and random errors or weekly control to correct for systematic error only. Noteworthy, in the weekly IGRT arm, a larger PTV was adopted to reduce the risk of recurrence, but also a rectal block to reduce the risk of toxicity potentially related to the larger PTV of this group of patients.

Publication date: Available online 24 May 2018 Source:Journal of Applied Biomedicine Author(s): Patrícia Borba Martiny, Diego Duarte Alcoba, Brasil Silva Neto, Paulo Costa Carvalho, Ilma Simoni Brum Prostate cancer (PCa) is the second most frequent cancer in men worldwide. Distinguishing between the nonaggressive and aggressive forms of this disease is difficult, and a means to better characterize molecular patterns that could aid in diagnosis is urgently needed. Here, we compare the proteomic profiles of PCa and benign prostatic hyperplasia (BPH) in an effort to elucidate underlying mechanisms of oncogenesis. We c...

AbstractThe goal of the study is to examine the possible use of HA (hyaluronic acid) and HAase (hyaluronidase) as novel urine biomarkers for the early diagnosis for prostate cancer (Pca). After a prostatic massage, the urine of 118 high-risk patients for Pca was collected, and the patients were submitted to ultrasound-guided transrectal biopsy. HA and HAase were detected and analyzed with Enzyme-Linked Immunosorbent Assay, and a statistical analysis of the urine levels of the two biomarkers according to the histology results was performed. HAase and HA were independently associated with Pca, and both HAase and HA showed si...
