Contemporary Diagnosis of Very Low-risk Prostate Cancer in a Multihospital Health Care System.

The National Comprehensive Cancer Network (NCCN) very low risk (VLR) category for prostate cancer (PCa) represents clinically insignificant disease, and detection of VLR PCa contributes to overdiagnosis. Greater use of magnetic resonance imaging (MRI) and biomarkers before patient selection for prostate biopsy (PBx) reduces unnecessary biopsies and may reduce the diagnosis of clinically insignificant PCa. We tested a hypothesis that the proportion of VLR diagnoses has decreased with greater use of MRI-informed PBx using data from our 11-hospital system. From 2018 to 2023, 351/3197 (11%) men diagnosed with PCa met the NCCN VLR criteria. The proportion of VLR diagnoses did not change from 2018 to 2023 (p = 0.8) despite an increase in the use of MRI-informed PBx (from 49% to 82%; p < 0.001). Of patients who underwent combined systematic and targeted PBx and were diagnosed with VLR disease, cancer was found in systematic PBx regions in 79% of cases and in targeted PBx regions in 31% of cases. When performing both systematic and targeted PBx, prebiopsy MRI-based risk calculators could limit VLR diagnosis by 41% using a risk threshold of >5% for Gleason grade group ≥3 PCa to recommend biopsy; the reduction would be 77% if performing targeted PBx only. These findings suggest that VLR disease continues to account for a significant minority of PCa diagnoses and could be limited by targeted PBx and risk stratification calculators. PATIENT SUMMARY: We looked at recent trends for the diagnosis of very low-risk (VLR) prostate cancer. We found that VLR cancer still seems to be frequently diagnosed despite the use of MRI (magnetic resonance imaging) scans before biopsy. The use of risk calculators to identify men who could avoid biopsy and/or biopsy only for lesions that are visible on MRI could reduce the overdiagnosis of VLR prostate cancer.

Ultrasensitive PSA: rethinking post-surgical management for node positive prostate cancer.

Introduction: Clinicians may offer patients with positive lymph nodes (pN1) and undetectable PSA following surgery for prostate cancer either observation or adjuvant therapy based on AUA, EAU, and NCCN guidelines considering standard PSA detection thresholds of <0.1ng/ml. Here we sought to investigate the outcomes of pN1 patients in the era of ultrasensitive PSA testing. Methods: We queried the Northwestern Electronic Data Warehouse for patients with prostate cancer who were pN1 at radical prostatectomy and followed with ultrasensitive PSA. Patients receiving neoadjuvant treatment were excluded. We compared clinical characteristics including age, race, pre-operative PSA, Gleason grade, tumor stage, surgical margins, and nodal specimens to identify factors associated with achievement and maintenance of an undetectable PSA (defined as <0.01 ng/mL). Statistics were performed using t-test, Mann-Whitney U test, chi-squared analysis, and logistic regression with significance defined as p<0.05. Results: From 2018-2023, 188 patients were included. Subsequently, 39 (20.7%) had a PSA decline to undetectable levels (<0.01 ng/mL) post-operatively at a median time of 63 days. Seven percent of these men (3/39) were treated with adjuvant RT + ADT with undetectable PSA levels. 13/39 (33.3%) had eventual rises in PSA to ≥0.01 ng/mL for which they underwent salvage RT with ADT. Overall, 23/39 (59%) patients achieved and maintained undetectable PSA levels without subsequent therapy at median follow-up of 24.2 mo. Compared to patients with PSA persistence after surgery or elevations to detectable levels (≥0.01 ng/mL), patients who achieved and maintained undetectable levels had lower Gleason grades (p=0.03), lower tumor stage (p<0.001), fewer positive margins (p=0.02), and fewer involved lymph nodes (p=0.02). On multivariable analysis, only primary tumor (pT) stage was associated with achieving and maintaining an undetectable PSA; pT3b disease was associated with a 6.6-fold increased chance of developing a detectable PSA (p=0.03). Conclusion: Ultrasensitive PSA can aid initiation of early salvage therapy for lymph node positive patients after radical prostatectomy while avoiding overtreatment in a significant subset. 20% of patients achieved an undetectable PSA and over half of this subset remained undetectable after 2 years.

Implementation of PSMA PET/CT and alignment of ordering to SNMMI appropriate use criteria in a large network system.

INTRODUCTION: The Society of Nuclear Medicine and Molecular Imaging (SNMMI) provides appropriate use criteria (AUC) for prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) which include guidance on imaging in newly diagnosed prostate cancer and in patients with biochemically recurrent (BCR) disease. This study aims to examine trends in PSMA implementation and the prevalence and outcomes of scans ordered in scenarios deemed rarely appropriate or not meeting SNMMI AUC. METHODS: We retrospectively identified patients who were diagnosed with presumptive National Comprehensive Cancer Network unfavorable intermediate, high, or very high risk prostate cancer, patients who underwent staging for BCR, and all patients staged with PSMA between July 2021 and March 2023. Positivity was validated by adherence to a predetermined reference standard. RESULTS: The frequency of PSMA use increased in initial staging from 24% to 80% and work-up of BCR from 91% to 99% over our study period. In addition, 5% (17/340) of PSMA scans ordered for initial staging did not meet AUC and 3% (15/557) of posttreatment scans were deemed rarely appropriate. Initial staging orders not meeting SNMMI AUC resulted in no positivity (0/17), while rarely appropriate posttreatment scans were falsely positive in 75% (3/4) of cases. Urologists (53%, 17/32) comprised the largest ordering specialty in rarely appropriate use. CONCLUSION: The frequency of PSMA use rose across the study period. A significant minority of patients received PSMA PET/CT in rarely appropriate scenarios yielding no positivity in initial staging and significant false positivity post-therapy. Further education of providers and electronic medical record-based interventions could help limit the rarely appropriate use of PET imaging.

'THIS IS NO COUNTRY FOR OLD (WO)MEN'? AN EXAMINATION OF THE APPROACH TAKEN TO CARE HOME RESIDENTS DURING THE COVID-19 PANDEMIC.

This article discusses the human rights of residents in care homes in England who were affected by restrictions that were imposed during the first months of the COVID-19 pandemic in order to safeguard health and life at a time of public health emergency. It focuses on the potentially adversarial relationship between the need to protect the health of these residents and the possible adverse interferences with their human rights in the initial phase of the pandemic. The scope and application of these rights to the healthcare context is not straightforward due to the exigencies of the pandemic. Consideration is given to whether their rights, as protected by the European Convention on Human Rights (ECHR) and the United Nations Convention on the Rights of Persons with Disabilities (CRPD) are vindicated or breached by the actions taken in the context of the COVID-19 pandemic. The article questions whether the restrictions that were applied were justified, given the limitations that exist within some ECHR Articles. It deliberates upon what can be done to ensure that relevant bodies and care homes, themselves, are better enabled to respond to a public health emergency in an individualistic, rights-based manner, based upon both principlism and pragmatism.

COVID-19 Vaccination and Legal Preparedness: Lessons from Ireland.

Ireland has been a leader in the COVID-19 vaccine rollout in the EU, with almost 80% of the eligible population (aged over 5 years) fully vaccinated at the time of writing. The success of the vaccine rollout in this jurisdiction notwithstanding, the legal frameworks supporting the rollout had significant lacunas. Two aspects in particular highlighted a lack of legal preparedness: the inadequacy of the legal framework for consent and the absence of a vaccine injury redress scheme. This paper explores these components of the COVID-19 vaccine rollout through the lens of legal preparedness. Whilst most often discussed in the context of command and control measures such as social distancing requirements and regional lockdowns, this paper argues for an expanded understanding of what it means to be legally prepared, highlighting the importance of the preparedness of domestic legal frameworks.

Re H (A Child) (Parental Responsibility: Vaccination): The Merits of Adopting A Softer Approach To Vaccination of A Child in Care?

In Re H (A Child) (Parental Responsibility: Vaccination), the Court of Appeal decided that vaccination did not represent 'grave' or 'serious' medical treatment and determined that, in the case of a child under the care of a Local Authority, court authorization for consent to and arrangement of vaccination is no longer required. This is due to the strong medical evidence in support of vaccination. Thus, with due reference to 33(3)(b) Children Act 1989 and while considering proportionality and, particularly, the proportionate response to interference with the parents' right to respect for private and family life under Article 8 of the European Convention on Human Rights, the court held that vaccination is in line with the best interests of the child. This commentary supports this judgment but identifies a slight prospective anomaly in the approach adopted to children in care and those who are not in care. The resolution of this dichotomy lies in broadening the scope of King LJ's approach in this case.
