Racial and ethnic differences in perceptions of germline or somatic DNA sequencing among patients with advanced prostate, urothelial, or kidney cancer.

We sought to determine racial and ethnic differences in perceptions (quality of communication, expectations, and concerns) of germline or somatic DNA sequencing (genomic profiling). Patients with prostate, urothelial, or kidney cancer were surveyed using a questionnaire that assessed previous experience, beliefs, expectations, and concerns regarding genomic profiling. Descriptive statistics and chi-square tests were used to identify factors associated with patients' perceptions of genomic profiling.

Changes in Perception of Cure Among Patients With Genitourinary Cancers Initiating Immune Checkpoint Inhibitors: A Longitudinal Study.

Background: We explored changes in perceptions of cure among patients with genitourinary (GU) cancers starting Immune checkpoint inhibitors (ICIs) therapy.

Materials And Methods: This longitudinal study assessed patients before starting therapy and 3-months later with a questionnaire that included patient perceptions of ICIs and the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety scale. General linear modeling was used to investigate changes in expectation of cure over time, and chi-square tests were used to determine the association between expectation of cure and perceptions of ICIs and anxiety.

Twitter as a Tool to Spread Communication Regarding Genitourinary Cancers During the COVID-19 Pandemic.

Objectives: To better characterize the relay of information about prostate, kidney, and bladder cancer on Twitter in relation to the COVID-19 pandemic.

Materials And Methods: Tweets containing the joint hashtags "#COVID-19" and either "#bladder cancer", "#kidney cancer", or "#prostate cancer" were identified on the Twitter platform from January 1, 2020 to July 30, 2020. The Twitter handle responsible for each tweet was categorized as an Academic, Medical Education, Patient Advocacy Groups/Non-Profits, Pharmaceutical, or Other entity based on content domain.

Circulating tumor DNA analysis of metastatic renal cell carcinoma.

The genomic landscape of metastatic renal cell carcinoma (RCC) is not well understood, and currently available data suggest that it is functionally distinct from that of localized tumors. Additionally, the large number of approved and trial agents used to treat metastatic RCC likely cause selective adaptations in the tumors. Circulating tumor DNA (ctDNA) is a platform to non-invasively determine the genomic profiles of these tumors.

Harnessing cell-free DNA: plasma circulating tumour DNA for liquid biopsy in genitourinary cancers.

In the era of precision oncology, liquid biopsy techniques, especially the use of plasma circulating tumour DNA (ctDNA) analysis, represent a paradigm shift in the use of genomic biomarkers with considerable implications for clinical practice. Compared with tissue-based tumour DNA analysis, plasma ctDNA is more convenient to test, more readily accessible, faster to obtain and less invasive, minimizing procedure-related risks and offering the opportunity to perform serial monitoring. Additionally, genomic profiles of ctDNA have been shown to reflect tumour heterogeneity, which has important implications for the identification of resistant clones and selection of targeted therapy well before clinical and radiographic changes occur.

Peroxisome proliferator-activated receptor gamma controls prostate cancer cell growth through AR-dependent and independent mechanisms.

Background: Prostate cancer (PC) remains a leading cause of cancer mortality and the most successful chemopreventative and treatment strategies for PC come from targeting the androgen receptor (AR). Although AR plays a key role, it is likely that other molecular pathways also contribute to PC, making it essential to identify and develop drugs against novel targets. Recent studies have identified peroxisome proliferator-activated receptor gamma (PPARγ), a nuclear receptor that regulates fatty acid (FA) metabolism, as a novel target in PC, and suggest that inhibitors of PPARγ could be used to treat existing disease.

First-Line Systemic Therapy for Metastatic Clear-Cell Renal Cell Carcinoma: Critical Appraisal of Emerging Options.

Until recently, a dichotomy existed in the front-line approach of metastatic clear-cell renal cell carcinoma (mRCC). Specifically, patients received either targeted therapy or immunotherapy. Targeted therapy entailed use of agents blocking signaling through the vascular endothelial growth factor (VEGF) receptor, such as cabozantinib, sunitinib, or pazopanib.

Different roles of peroxisome proliferator-activated receptor gamma isoforms in prostate cancer.

Due to the increasing occurrence of and high costs associated with prostate cancer (PC), there is an urgent need to develop novel PC treatment and chemoprevention strategies. Although androgen receptor (AR) signaling is significant in the development and progression of PC, other molecular pathways contribute as well. Peroxisome Proliferator-Activated Receptor Gamma (PPARγ) has recently been implicated as an oncogene in PC, which may influence both the development and metastatic progression of the cancer.

The Changing Landscape of Management of Metastatic Renal Cell Carcinoma: Current Treatment Options and Future Directions.

For the practicing clinician, the dilemma becomes how most appropriate to sequence the aforementioned regimens. It is challenging to be dogmatic, as there are no comparative studies juxtaposing novel front-line options directly-all of the available studies utilize a comparator arm of sunitinib. With this in mind, the selection of front-line therapy with a patient with mRCC should involve a thorough discussion of both efficacy and safety of available options.

Examining Public Communication About Kidney Cancer on Twitter.

Purpose: Several studies have described the content of Twitter conversations about lung, breast, and prostate cancer, but little is known about how the public uses Twitter to discuss kidney cancer. We sought to characterize the content of conversations on Twitter about kidney cancer and the participants engaged in these dialogues.

Methods: This qualitative study analyzed the content of 2,097 tweets that contained the key words kidney cancer from August 1 to 22, 2017.

Role of Biomarkers in Prediction of Response to Therapeutics in Metastatic Renal-Cell Carcinoma.

Renal-cell carcinoma remains one of the elusive cancers that lacks a biomarker. It is the eighth most commonly diagnosed malignancy in the United States, and the incidence has slowly trended upward. In addition to the increase in newly diagnosed cases, the prevalence and overall survival of individuals with kidney cancer also has increased substantially.

Modulation of Premetastatic Niche by the Vascular Endothelial Growth Factor Receptor Tyrosine Kinase Inhibitor Pazopanib in Localized High-Risk Prostate Cancer Followed by Radical Prostatectomy: A Phase II Randomized Trial.

Lessons Learned: Pazopanib was not effective in altering the premetastatic niche in the neoadjuvant setting.Pazopanib was safe and well tolerated without any new safety signals.

Background: Vascular endothelial growth factor receptor 1 (VEGFR1) expressing myeloid-derived suppressor cells (VEGFR1+ MDSCs) potentially foster metastases by establishing a premetastatic niche.

Non-Clear Cell Renal Cell Carcinoma: Current Management and Best Practice.

The treatment of metastatic renal cell carcinoma (mRCC) has evolved markedly over the past several decades; first with the introduction of targeted therapies and more recently with data supporting checkpoint inhibition. However, the vast majority of studies to date have explored the benefit of agents specifically in the context of clear cell disease. For the estimated 15-20% of patients with non-clear cell histology, there is little consensus around best practice.

Assessment of distress and quality of life in rare cancers.

Objective: Rare cancers are a heterogeneous group of conditions that can be associated with emotional and physical impairments. In view of the dearth of research in this area, we investigated the quality of life and prevalence of distress in a cohort of patients diagnosed with a rare cancer, classified by the RARECARE definition.

Methods: A cohort of rare cancer patients, treated in a Brazilian public cancer center, was assessed for distress (Distress Thermometer), anxiety/depression (Hospital Anxiety and Depression Scale), and quality of life (Functional Assessment of Cancer Therapy-General Version).

Advances in the Treatment of Metastatic Renal Cell Carcinoma.

The treatment landscape for metastatic renal cell carcinoma has constantly been in flux. In 2005, with the advent of vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) therapy, the standard of care shifted to agents such as sunitinib and pazopanib. However, more recently there have been datasets, suggesting that next-generation TKIs such as cabozantinib may play an important role in therapy.

Concomitant Radioembolization and Immune Checkpoint Inhibition in Metastatic Renal Cell Carcinoma.

This case represents the challenge and creativity necessary when treating patients with metastatic renal cell carcinoma who have been exposed to multiple lines of therapy. At present, treatment with immune checkpoint inhibition has stabilized and improved the metastatic disease of this patient with the exception of hepatic lesions. This isolated progression within the liver led the employment of radioembolization, which successfully treated those metastases.

Therapeutic Sequencing in Metastatic Renal Cell Carcinoma.

The influx of multiple novel therapeutic options in the mRCC field has brought a challenge for treatment sequencing in this disease. In the past few years, cabozantinib, nivolumab and the combination of lenvatinib and everolimus have been approved in the second-line setting. As there is no direct comparison between these agents and the studies have failed to show improved benefit among a biomarker-selected patient population, appropriate patient selection based on clinical factors for individualized therapy is critical.
