Assays Predict Non-responders to Advanced Prostate Cancer Therapies Assays Predict Non-responders to Advanced Prostate Cancer Therapies

Two circulating tumor cell (CTC) assays can predict which men with advanced prostate cancer are unlikely to benefit from anti-androgen therapies, researchers said in a June 4 presentation at ASCO 2018.Reuters Health Information

CONCLUSIONS: Our preliminary data demonstrate that ozone therapy is a valid supportive therapy for fatigue in cancer patients, both during cancer therapy and in a palliative setting with no significant side effects. PMID: 30536352 [PubMed - in process]

In this study, prostate-specific membrane antigen (PSMA)-targeted and core-crosslinked micelles were developed based on prostate cancer-binding peptide (PCP) modified glycol chitosan-lipoic acid (PGC-LA) conjugate. The degree of substitution was 5.2 PCP groups and 10.7 lipoic acid groups per 100 sugar residues of glycol chitosan in PGC-LA copolymer. Docetaxel (DTX) was chosen as a model anti-tumor drug. The DTX-loaded micelles were prepared by an o/w method, and core-crosslinked micelles were further constructed by using a catalytic amount of dithiothreitol. The mean diameter of DTX-loaded core-crosslinked PGC-LA (DTX-PGC-...

Our results showed that reticulon ‐4 (RTN4) was downregulated and targeted by miR‐148a‐3p, and inhibited prostate cancer cell proliferation by inducing cell cycle arrest and senescence, suggesting that RTN4 may be an important molecular event linked to prostate cancer. AbstractReticulon ‐4 (RTN4), a reticulon family protein localized in the endoplasmic reticulum, is reported to be involved in multiple physiological processes like neuroendocrine secretion and membrane trafficking in neuroendocrine cells. Previous studies have presented a great potential of RTN4 for the treatment o f autoimmune‐mediated demyelinati...

ConclusionsctDNA profiles appear to mirror the genomic landscape of metastatic prostate cancer tissue and may cost-efficiently provide somatic information in clinical trials designed to identify predictive biomarkers. However, intronic sequencing of the interrogated tumor suppressors challenges the ubiquitous focus on coding regions and is vital, together with profiling of synchronous white blood cells, to minimize erroneous assignments which in turn may confound results and impede true associations in clinical trials.

ConclusionsFindings from this study highlight that real-world experience of docetaxel may differ from that observed in clinical trials and that care must be taken to ensure that treatment options are tailored to the needs of individual patients to promote not only how long patients survive but also the quality of that survival.FundingJanssen

AbstractClinical studies have demonstrated the benefits of abiraterone acetate  + prednisone (AAP) and enzalutamide (ENZ) in significantly improving survival among metastatic castration‐resistant prostate cancer (mCRPC) patients. However, evidence regarding patient's real‐world experience, particularly with respect to fatigue, treatment satisfaction and health‐related quality of life (HRQoL) is limited. Interviews were initially conducted with patients (n = 38) and carers (n = 12) to elicit qualitative data regarding their experiences. Findings informed the design of a quantitative, mult...

Despite major scientific advances, cancer remains one of the leading causes of death in the world with more than 90% of cancer mortality is due to metastasis rather than primary disease [1]. In addition, some of the current cancer therapies might promote cancer recurrence and metastasis, e.g., radiation therapy is designed to kill tumor cells; however, it could also be a cause of cancer recurrence and metastasis especially with epithelial cell cancers such as lung and prostate cancer [2]. Consequently, there is an urgent need to develop new therapies which can eradicate tumor cells and eliminate the probability of cancer r...

SummaryExpression of CD155 differs between tumor and normal tissues, and high expression of this molecule can promote tumor metastasis. Here, we investigate whether CD155 can serve as a target for T cell-mediated immunotherapy of human prostate cancer. We first demonstrate that prostate cancer cells, including PC-3, PC-3  M, and LNCAP cells, express CD155 at high levels. Next, the specific cytotoxic activity of activated T cells (ATCs) armed with a novel anti-CD3 × anti-CD155 bispecific antibody (CD155Bi-Ab) against tumor cells was evaluated by flow cytometry, lactate dehydrogenase assay (LDH), and ELI...

Abstract Statins are commonly used in the middle-aged and elderly people for treatment of hyperlipidemia. Both alpha lipoic acid (ALA) and ellagic acid (EA) are natural antioxidants found in a normal diet. They can protect against cellular damage and induce cellular apoptosis in many types of cancer cells. Fluvastatin (FLV) was combined with ALA and EA in a nanostructured lipid carrier (NLC) formula. The prepared NLCs were imaged with a transmission electron microscope (TEM). Particle size and zeta potential and FLV entrapment efficiency (%EE) were measured, and the FLV release profile was constructed. Cellular vi...
