What is Changing in Advanced Prostate Cancer?

Published in Everyday Urology - Oncology Insights: Volume 5, Issue 2

Introduction

Prostate cancer, while commonly diagnosed in early forms, remains the second leading cause of cancer mortality in the United States and Europe.¹ For patients who die of prostate cancer, some will be initially diagnosed and treated for metastatic castration-sensitive disease (mCSPC) while others will progress through non-metastatic castration-resistant disease (nmCPRC) following initial local therapy followed by androgen deprivation therapy (ADT) for biochemical recurrence. In either case, nearly all men who die of prostate cancer will have metastatic castration-resistant disease (mCRPC) prior to death.

In 2015, cisplatin-ineligible patients with metastatic urothelial carcinoma could not be offered a first-line treatment option capable of prolonging their survival. Also, a paucity of second-line treatments resulted in these same patients usually surviving for only 3 to 6 months after progressing on platinum-treatment.

Percutaneous Renal Biopsy in the Ambulatory Surgery Center: A Primer

Published in Everyday Urology - Oncology Insights: Volume 5, Issue 1

Published Date: March 2020

The earliest renal biopsies were obtained by open surgical techniques performed by urologists or transplant surgeons, or by pathologists at the time of autopsy. In 1951, physicians in Copenhagen published the first clinical report of percutaneous renal biopsy.¹ They placed patients in a seated position and used intravenous pyelogram (IVP) as the imaging guide. Not surprisingly, both the yield and quality of biopsy tissue samples were low by contemporary standards, with only about half to two-thirds of specimens permitting histologic examination.

Urinary tract infections are the most common type of bacterial infection,¹ accounting for at least 11 million physician office visits, 2 to 3 million emergency department visits, 400,000 hospitalizations, and approximately $2.3 billion in healthcare costs annually in the United States.^2,3,4,5

Choosing First-Line Treatment for Metastatic Castration-Resistant Prostate Cancer: APCCC Highlights

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 4

Published Date: December 2019

The choice of initial treatment for newly diagnosed metastatic castration-resistant prostate cancer (mCRPC) is far more complex than it was even a decade ago. Today, many patients with mCRPC have already received intensive upfront therapies during the hormone-sensitive stage— a “leftward” shift in treatment (based on the clinical states model we so frequently employ) which can spur a “rightward” shift in disease biology due to the earlier emergence of treatment-resistant clones.

Choosing First-Line Systemic Therapy for Newly Diagnosed Metastatic Hormone Sensitive Prostate Cancer

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 4

Published Date: December 2019

Metastatic hormone-sensitive prostate cancer (mHSPC) has become increasingly prevalent in the United States. Between 2009 and 2020, experts have projected a nearly 17% increase in the number of newly diagnosed mHSPC cases and a more than 18% increase in cases of mHSPC occurring after failure of local (curative-intent) treatment.¹ This increase is likely multifactorial, reflecting changes in prostate-specific antigen (PSA) screening practices, the increased use of more sensitive imaging modalities, and other factors.^{2, 3}

Controversies with PSMA-Based Imaging and Targeted Therapy

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 4

Published Date: December 2019

Prostate-specific membrane antigen (PSMA) is expressed 100 to 1,000 times more highly in prostatic adenocarcinoma than in benign prostate tissue, particularly in the setting of androgen deprivation.¹ Around the world, we are seeing the rapid adoption of PSMA PET-CT/MRI, which is able to detect metastatic disease that is inapparent on conventional imaging (CT and bone scintigraphy). It remains unclear, however, if the earlier detection of asymptomatic metastatic disease improves clinical outcomes for patients. Various questions and controversies also surround the emerging field of PSMA-based targeted therapies.

A Review of Comprehensive Bone Health Management Strategies for Men with Prostate Cancer

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 4

Published Date: December 2019

Bone health is a critical area of unmet need among men with advanced prostate cancer. Age increases the risk for fragility fractures among both men and women, and older men with fragility fractures are at higher risk of subsequent death than are women.^1-3 Systemic anti-androgen therapies for prostate cancer, while life-prolonging, accelerate bone loss by tipping the balance of bone homeostasis toward bone resorption, which further increases patients’ risk of fragility fractures.⁴

Monitoring and Managing Toxicities in Patients with Metastatic Hormone-Sensitive Prostate Cancer

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 4

Published Date: December 2019

A 65-year-old man presents with skeletal pain. His PSA is 101 ng per mL, computed tomography (CT) reveals pelvic lymphadenopathy, a 99mTc bone scan shows extensive bone metastases, and prostate biopsy cores are interpreted as Gleason score 9 with intraductal features. The patient starts long-term androgen-deprivation therapy (ADT) and completes five cycles of docetaxel. His pain resolves. His PSA declines but remains persistently elevated at 2.6 ng per mL, so the decision is made to add enzalutamide, a next-generation androgen receptor (AR)-targeted therapy, to ADT.

Genetic Evaluation of Hereditary Prostate Cancer

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 2

Published Date: June 2019

During much of the past 30 years, genetic tests for heritable disorders have assessed limited numbers of genes and have often employed serial testing algorithms in which the next test was determined by the results of the prior test.¹ The advent of next-generation (also known as massively parallel high-throughput) sequencing has transformed this picture by making it possible to sequence the entire human genome for less than $1,000.^1,2

Darolutamide: Approved For Non-Metastatic Castration-Resistant Prostate Cancer

Published Date: September 2019

Androgen deprivation therapy (ADT) is the longstanding initial treatment for advanced hormone-sensitive prostate adenocarcinoma. Nonetheless, patients who are initiated on ADT will invariably progress by developing prostate cancer cellular clonal populations, which creates a phenotype of more castration-resistant disease with more aggressive biology.¹

Preparing Your Practice for the New Era of Theranostics

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 3

Published Date: September 2019

Patients whose metastatic castration-resistant prostate cancer (mCRPC) has progressed on taxane chemotherapy and second-generation anti-androgen agents have few alternatives to palliative care. However, radiolabeled prostate-specific membrane antigen (PSMA) conjugates are now in latephase studies. In this article, I discuss theranostics, the phase 3 VISION trial, and the questions we will need to consider when PSMA-targeted radioligand therapies become available for use in our advanced prostate cancer clinics.

Optimizing Bone Health in Prostate Cancer

Published in Everyday Urology - Oncology Insights: Volume 4, Issue 2

Published Date: June 2019

Protecting and improving bone health is critical when managing all stages of prostate cancer. Androgen deprivation therapy (ADT) accelerates bone resorption, which compromises bone mass and integrity starting early in treatment.¹ Metastatic prostate cancer is associated with a marked increase in risk of skeletal events (fracture, spinal cord compression, and bone surgery or radiotherapy) associated with both bone metastases and treatment-induced bone loss.

The detection of recurrent tumor is a benchmark by which the success of intravesical agents is determined. Because the U.S. Food and Drug Administration (FDA) will now consider data from single-arm trials for patients with Bacillus Calmette-Guérin (BCG)-unresponsive bladder cancer, the complete response (CR) rates (i.e. absence of disease on biopsy) is a key factor that impacts the success of many registration studies.

Immuno-Oncology: The Urologist's Role

Published in Everyday Urology - Oncology Insights: Volume 4 Issue 1

Published Date: March 2019

This is an extraordinary time in urology. After decades of relative stagnation, patients with urothelial carcinoma are receiving approved immuno-oncologic drugs that significantly extend survival and are safer and more tolerable than chemotherapy. The success of these treatments in metastatic bladder cancer has generated strong interest and promising early results for their use in localized disease.

Update on ADT in Advanced Prostate Cancer

Published Date: September 2018

A 62-year-old man presents with a one-week history of hematuria. Ultrasound and computed tomography identify a 7-cm exophytic anterior left renal tumor, adenopathy, and two
small lung nodules. No bone or central nervous system lesions are detected. His Eastern Cooperative Oncology Group (ECOG) performance-status (PS) and Memorial Sloan-Kettering Cancer Center (MSKCC) scores are 1. The patient asks whether to undergo cytoreductive nephrectomy. What do you tell him?

Spacers and Prostate Radiation Therapy: What Urologists Should Know

Published in Everyday Urology - Oncology Insights: Volume 3, Issue 3

Published Date: September 2018

Radiation has been used to treat prostate cancer since the early 1900s.¹ In recent decades, advances in radiation delivery systems and the advent of computed tomography and magnetic resonance imaging have spurred the development of targeted, high-dose radiotherapy techniques such as intensity-modulated radiotherapy (IMRT), image-guided radiation therapy (IGRT), stereotactic radiation therapies, proton beam
