RETROSPECTIVE The Genomics of Prostate Cancer: A Historic Perspective

The genomics of prostate cancer (PCA) has been difficult to study compared with some other cancer types for a multitude of reasons, despite significant efforts since the early 1980s. Overcoming some of these obstacles has paved the way for greater insight into the genomics of PCA. The advent of high-throughput technologies coming from the initial use of microsatellite and oligonucleotide probes gave rise to techniques like comparative genomic hybridization (CGH). With the introduction of massively parallel genomic sequencing, referred to as next-generation sequencing (NGS), a deeper understanding of cancer genomics in general has occurred. Along with these technologic advances, there has been the development of computational biology and statistical approaches to address novel large data sets characterized by single base resolution. This review will provide a historic perspective of PCA genomics with an emphasis on the cardinal mutations and alterations observed to be consistently seen in PCA for both hormone-naïve localized PCA and castration-resistant prostate cancer (CRPC). There will be a focus on alterations that have the greatest potential to play a role in disease progression and therapy management.

TahtamouniAbstractCephalostatin 1, a potent anti-cancer agent, is a natural bis-steroidal alkaloid that causes cell death in the subnanomolar to picomolar ranges via an atypical apoptosis pathway. Although cephalostatin 1 is a highly effective anticancer drug, its availability limits its utilization. We previously reported the synthesis of two 12'α-hydroxy derivatives of cephalostatin 1 that induce cell death by activating the ER str...

ConclusionsThe RT techniques for the treatment of PCa are statistically equivalent with respect to the bRFS rate. This paper confirms that the bRFS rates of Mexican PCa patients who were treated with conventional vs. hypofractionated schemes do not differ significantly.

ConclusionsThe significant association between both objective and subjective FT and HRQoL highlights the importance of reducing FT among urologic cancer patients. Subjective FT was found to have a greater negative impact on HRQoL.

CONCLUSIONS: MDT is highly appealing given its potential to delay disease progression and adverse events of systemic therapy. Nonetheless, data remains immature to recommend MDT on a large scale and the selection criteria for patients have yet been defined. Today, MDT should be administered within a clinical trial and results of future research are eagerly awaited. PMID: 32083417 [PubMed - as supplied by publisher]

CONCLUSIONS: Neutrophil-to-lymphocyte ratio does not have clinical utility for the prediction of adverse pathology and biochemical recurrence. Further research should focus on its value for predicting regional lymph node metastasis. PMID: 32083416 [PubMed - as supplied by publisher]

ConclusionsOur data indicate a higher overall expression of MMP-2 and MMP-9 in the tumor area of the RP compared to the corresponding areas of the negative previous biopsy, which seems to be associated to the process of malignant transformation.ResumenLas metaloproteasas (MMPs) y el inhibidor tisular de metaloproteasas-3 (TIMP-3) se han relacionado con el riesgo de padecer cáncer y con la agresividad de varios tumores. En ocasiones, existen muchas dificultades para diagnosticar el cáncer de próstata (CaP), la expresión de MMPs y del TIMP-3 en biopsias negativas nos podría ayudar a realiza...

Thousands of men across the world have participated in randomized clinical trials testing the role of hormone therapy in the curative treatment of localized, high-risk prostate cancer. Over several decades, we have established that long-term hormone therapy improves survival, even in the setting of dose-escalated external beam radiation therapy (EBRT).1 Recently reported clinical trials suggest that for some men 18 months of hormone therapy may be a suitable duration that balances treatment efficacy with quality-of-life preservation.

Lawrie Prostate cancer (PCa) is the second most common cancer of men and is typically slow-growing and asymptomatic. The use of blood PSA as a screening method has greatly improved PCa diagnosis, but high levels of false positives has raised much interest in alternative biomarkers. We used next-generation sequencing (NGS) to elucidate the urinary transcriptome of whole urine collected from high-stage and low-stage PCa patients as well as from patients with the confounding diagnosis of ben...
