Pluvicto-Induced 18 F-PSMA PET Bone Flare.

ABSTRACT: A 79-year-old man with a history of metastatic prostate cancer was initially treated with Eligard and switched to relugolix in 2021. The 2022 bone scan presented superscan and extensive osseous metastatic lesions; some had intense PSMA uptake on the initial PSMA PET scan without nodal or visceral metastatic lesions. We treated him with Pluvicto and relugolix. The intermediate PSMA scan demonstrated prominent bone marrow PSMA uptake. However, PSA decreased 58.5%. We hypothesized that the patient might have a bone flare. The final PSMA scan confirmed our hypothesis. Based on our knowledge, this is the first case of Pluvicto-induced bone flare.

Review of Palliative 223Ra in Metastatic Castration-Resistant Prostate Cancer: Experience at West Virginia University Cancer Center.

The ALSYMPCA trial of the α-emitter 223Ra in symptomatic bone-predominant metastatic castration-resistant prostate cancer (mCRPC) reported a median overall survival (OS) of 14.9 mo, versus 11.3 mo for placebo. However, subsequently reported real-world experience with 223Ra in smaller mCRPC patient cohorts has appeared less successful. We performed a retrospective observational study to review our own 223Ra experience at West Virginia University (WVU). Methods: Demographic, clinical, laboratory, and imaging data were reviewed in all bone-predominant mCRPC patients treated with 223Ra at WVU from 2014 to 2019. The number of bone metastases per patient at the start of treatment with 223Ra was quantified via nuclear bone scans (12 scans, 5 of which also included SPECT/CT), body CT scans (8 scans), and PET/CT scans (4 scans). Standard descriptive statistics were used to study institutional review board-exempted, deidentified patient data. Median survival in ALSYMPCA and WVU patients was compared using a 2-sided, 1-sample log-rank test based on the exponential distributions. The primary endpoint was patient OS after initiating 223Ra. Results: Twenty-four patients received 98 infusions of 223Ra; 83% of these patients were referred from outside WVU. Before the first infusion, all 24 had received androgen deprivation therapy. In total, 73 sequential combinations of androgen deprivation therapy were used, 68 of which (93%) preceded the first 223Ra infusion. Also, before 223Ra, 19 (79%) patients had received docetaxel and 19 (79%) had received 33 courses of radiation, 24 of which targeted nonprostatic sites. Eleven patients (46%) completed all 6 planned 223Ra infusions; 13 (54%) stopped early because of clinical deterioration. As of August 2020, only 1 patient remained alive after completing 6 cycles of 223Ra. Median OS from the first 223Ra infusion to the last follow-up or death was 8.3 mo (range, 0-44 mo)-nearly 50% less than the ALSYMPCA median survival of 14.9 mo (P = 0.01). Compared with ALSYMPCA, more WVU patients received bisphosphonates and docetaxel, more had an Eastern Cooperative Oncology Group performance status of at least 2, more used opiates for pain, more had a greater bone metastasis burden by imaging, and more had lower hemoglobin, albumin, alkaline phosphatase, and prostate-specific antigen levels. Conclusion: Although the science supporting the development and clinical use of 223Ra is compelling, optimal clinical benefit will likely require earlier referral for 223Ra, before patients have exhausted most conventional therapies. At WVU, we found that practically all our referred patients had androgen deprivation therapy, radiation, and cytotoxic therapy before starting 223Ra. We continue to offer 223Ra therapy to patients with symptomatic bone-predominant mCRPC but are encouraging earlier patient referral.

Perceptions of oral health by the WV community.

BACKGROUND: This survey was undertaken to establish baseline measurements in regards to the oral health beliefs and practices of the general public throughout West Virginia as a starting point to create an effective educational initiative fostering oral health as an integral component of health. METHODS: A population based 37 item telephonic opinion survey on a representative sample of WV state wide residents was conducted to understand practices, habits and experiences with oral health, to identify barriers to oral health, and determine the perception of its importance to other health conditions. RESULTS: West Virginians rank obesity as the most serious health problem and dental health a significantly less serious concern. Half admitted to less than good dental health. Cost was most commonly cited for not accessing oral care. CONCLUSIONS: A unified health promotion message among all health care providers is vital if general health of West Virginia citizens is to be improved. The links between oral health, coronary artery disease, diabetes, and pulmonary conditions can be used as a common starting point to embrace health advancement in general with the ultimate goal of changing current attitudes and practices and develop sustainable health programs that result in positive oral health/overall health in individuals and communities.
