Knowledge of Pelvic Floor Dysfunction in African American and Afro-Caribbean Women Seeking Medical Care in a Primary Care Ambulatory Setting.

IMPORTANCE: Approximately one fourth of U.S. community-dwelling women will develop a pelvic floor dysfunction (PFD) within their lifetimes. Prior research has revealed that knowledge of PFD was low to moderate in the general population and lower among Black patients. OBJECTIVE: This study aimed to assess the proficiency of urinary incontinence and pelvic organ prolapse (POP) in self-identified African American and Afro-Caribbean adult (age ≥ 18 years) female patients seeking medical care in our ambulatory setting. STUDY DESIGN: In this cross-sectional study, we administered the Prolapse and Incontinence Knowledge Questionnaire to patients in primary care and gynecology ambulatory settings at an academic medical center in Central Brooklyn. We used a multivariable Poisson regression model to find characteristics of the participants that are associated with proficiency in Prolapse and Incontinence Knowledge Questionnaire domains. RESULTS: A total of 266 survey participants self-identified as African American or Afro-Caribbean. Overall, using a multivariable model, knowledge of POP was significantly higher among African Americans than Afro-Caribbeans, and 75.5% of our patients reported that they would seek information on urinary incontinence and POP from a medical provider (gynecologist or primary care doctor) compared with other alternatives (eg, internet, 19.6%). CONCLUSIONS: These findings highlight subgroups that could benefit from provider-initiated education regarding PFD. Furthermore, although Black patients are often homogenized in research studies, differences may exist within subgroups likely because of varying interplays of structural racism and other social determinants of health, which may serve as an area of future research.

Patterns of Recurrence and Modes of Progression After Metastasis-Directed Therapy in Oligometastatic Castration-Sensitive Prostate Cancer.

PURPOSE: Metastasis-directed therapy (MDT) is increasingly used in castration-sensitive oligometastatic prostate cancer because it prolongs progression-free survival (PFS) and androgen deprivation free survival. Here we describe patterns of recurrence and identify modes of progression after MDT using SABR. METHODS AND MATERIALS: Two hundred fifty-eight patients with castration-sensitive oligometastatic prostate cancer (≤5 lesions at staging) were retrospectively identified from a multi-institutional database. Descriptive patterns of recurrence and modes of progression were reported. Other outcomes including median time to prostate-specific antigen (PSA) recurrence, time to next intervention, distant metastasis-free survival, overall survival, and biochemical PFS (bPFS) were reported. Survival analysis was performed using the Kaplan-Meier method, and multivariable analysis was performed. RESULTS: Median follow-up was 25.2 months, and 50.4% of patients received concurrent androgen deprivation. Median time to PSA recurrence was 15.7 months, time to next intervention was 28.6 months, distant metastasis-free survival was 19.1 months, and bPFS was 16.1 months. Two-year overall survival was 96.8%. On multivariable analysis, factors associated with bPFS included age (hazard ratio [HR], 1.03; P = .04), N1 disease at diagnosis (HR, 2.00; P = .02), M1 disease at diagnosis (HR, 0.44; P = .01), initial PSA at diagnosis (HR, 1.002; P = <.001), use of androgen deprivation therapy (HR, 0.41; P < .001), pre-SABR PSA (HR, 1.02; P = .01), and use of enhanced imaging for staging (HR, 2.81; P = .001). Patterns of progression favored an osseous component at recurrence; in patients initially treated to a bone lesion alone, the vast majority (86.5%) experienced a recurrence that included an osseous site. Patients treated initially to a nodal site alone tended to recur in a node only (64.5%); however, there was also a significant minority with an osseous component of recurrence at progression (32.3%). Modes of progressors were class I (patients with long term control [no recurrence ≥18 months after therapy]) occurring in 40.9%, class II (oligoprogressors [≤3 lesions at recurrence]) occurring in 36% (including 7.9% of patients with PSA recurrence but no metastatic disease), and class III (polyprogressors [>3 lesions]) occurring in 23.1% of patients. CONCLUSIONS: After MDT, the majority of patients have long-term control or oligoprogression (class I or II). Recurrence tended to occur in osseous sites. These findings, if validated, have implications for future integration of MDT and clinical trial design.

Early biochemical predictors of survival in intermediate and high-risk prostate cancer treated with radiation and androgen deprivation therapy.

BACKGROUND AND PURPOSE: To identify early biochemical predictors of survival in intermediate- and high-risk prostate cancer patients with a pre-treatment PSA <20 ng/mL following definitive radiation therapy (RT) and androgen deprivation therapy (ADT). MATERIALS AND METHODS: A single-institution review of 2566 intermediate and high-risk prostate cancer patients treated with definitive RT and neoadjuvant and concurrent ADT from 1990 to 2012 was performed. The first prostate-specific antigen (PSA) value within three months of ADT initiation (post-ADT PSA) and the first PSA within three months after RT completion (post-RT PSA) were recorded. 1275 had baseline PSA <20 ng/mL and either post-ADT or post-RT PSA available. Median follow-up was 7.6 years. The relationship between post-treatment PSA kinetics and biochemical relapse (BR), distant metastasis (DM), prostate cancer specific death (PCSD) and overall survival (OS) was modeled using Cox regression univariate and multivariate analysis (MVA). RESULTS: MVA demonstrated a strong association between a post-RT PSA ≥0.09 ng/mL and a significantly higher risk of BR (HR: 1.93; 95% CI: 1.45-2.57; p < 0.001), DM (HR: 2.97; 95% CI: 2.01-4.39; p < 0.001), PCSD (HR: 2.99; 95% CI: 1.73-5.15; p < 0.001) and OS (HR: 1.49; 95% CI: 1.18-1.86; p < 0.001). Post-RT PSA reduction of ≥95% relative to the baseline PSA was associated with a significantly lower risk of BR (MVA HR: 0.58; 95% CI: 0.41-0.83; p = 0.003) and DM (MVA HR: 0.47; 95% CI: 0.30-0.76; p = 0.002). CONCLUSION: A PSA value ≥0.09 ng/mL early after RT completion is associated with significantly worse prognosis across all clinical outcomes, and an early PSA reduction of ≥95% is associated with reduced risk of BR and DM. These findings may identify patients who require early aggressive systemic management for high-risk disease.
