Treatment Patterns and Outcomes in Pancreatic Cancer: A Comparative Analysis of Ontario and the USA.

BACKGROUND: Comparative studies evaluating quality of care in different healthcare systems can guide reform initiatives. This study seeks to characterize best practices by comparing utilization and outcomes for patients with pancreatic cancer (PC) in the USA and Ontario, Canada. METHODS: Patients (age ≥ 66 years) with PC were identified from the Ontario Cancer Registry and SEER-Medicare databases from 2006 to 2015. Demographics and treatment (surgery, radiation, chemotherapy, or multimodality (surgery and chemotherapy)) were described. In resected patients, neoadjuvant therapy, readmission, and 30- and 90-day postoperative mortality rates were calculated. Survival was assessed using Kaplan-Meier curves. RESULTS: This study includes 38,858 and 11,512 patients with PC from the USA and Ontario, respectively. More female patients were identified in the USA (54.0%) versus Ontario (46.9%). In the entire cohort, US patients received more radiation in addition to other therapies (18.8% vs. 13.5% Ontario) and chemotherapy alone (34.3% vs. 19.0% Ontario). While rates of resection were similar (13.4% USA vs.12.5% Ontario), multimodality therapy was more common in the UAS (9.0% vs. 6.4%). Among resected patients, neoadjuvant chemotherapy was uncommon in both groups, although more frequent in the USA (12.0% vs. 3.2% Ontario). The 30- and 90-day postoperative mortality rates were lower in Ontario vs. the USA (30-day: 3.26% vs. 4.91%; 90-day: 7.08% vs. 10.96%), however, overall survival was similar between the USA and Ontario. CONCLUSIONS: We observed substantive differences in treatment and outcomes between PC patients in the USA and Ontario, which may reflect known differences in healthcare systems. Close evaluation of healthcare policies can inform initiatives to improve care quality.

Analysis of diurnal variation in serum testosterone levels in men with symptoms of testosterone deficiency.

BACKGROUND: Testosterone (T) plays a crucial role in various physiological functions in men, and understanding the variations in T levels during the day is essential for diagnosing and treating testosterone deficiency (TD). AIM: We sought to evaluate the reduction in serum total T (TT) levels throughout the day in men with symptoms of testosterone deficiency and to determine the variables having an impact on the extent of this decline. METHODS: The study population consisted of a group of men who within 3 months of each other had all undergone both early morning and afternoon TT level measurements. We did not include patients with a history of a prior orchiectomy, testosterone levels below 100 ng/dL or above 1000 ng/dL, a history of androgen deprivation therapy, or patients on T therapy. Statistical analyses were conducted using descriptive statistics, t-tests, chi-square tests, and correlation calculations. Liquid chromatography-tandem mass spectrometry was used to measure TT, and a change in TT levels greater than 100 ng/dL was considered significant. Using multivariable and univariable analysis, we attempted to define predictors of a decrease in afternoon TT levels. OUTCOMES: The majority of men showed no significant difference in T levels between morning and afternoon. RESULTS: In total, 506 men with a median age of 65 years were analyzed. The most common comorbidities were hypertension and hyperlipidemia. Levels of TT were measured in the morning and afternoon, and no significant differences in mean T levels based on the time of the test were found. Age was not significantly associated with T levels. CLINICAL IMPLICATIONS: There was a weak negative correlation between age and the difference between morning and afternoon T levels, with younger men showing more significant variations in T levels. The most considerable differences in T levels were observed in men younger than 30 years. There were no predictors of the magnitude of the T decrease in the afternoon. STRENGTHS AND LIMITATIONS: Strengths of the study include the number of subjects and the use of liquid chromatography-tandem mass spectrometry for T measurement. Limitations include failure to measure morning and afternoon T levels on the same day, the retrospective nature of the study, and a smaller sample size of patients younger than 30 years. CONCLUSION: In this study we found no strong link between age and daily T fluctuation, but we observed a decrease in the magnitude of variation with aging. The group experiencing the most significant decline in daily T had higher morning and consistently normal afternoon T levels.

Cognitive effects of long-term androgen deprivation therapy in older men with prostate cancer.

OBJECTIVE: Androgen deprivation therapy (ADT) is a common treatment for prostate cancer (PCa), with increasing numbers of men on ADT for longer. Limited evidence suggests ADT impacts cognition. This study addressed gaps in the literature by focusing on older men with PCa and assessing ADT usage longer than 1 year. METHODS: This study of 133 men ≥65 years of age with PCa included two groups: (1) men on ADT for 1-3 years (ADT-exposed), and (2) a comparison group of men with PCa not on ADT (ADT-unexposed). Group comparisons on individual neuropsychological test scores are reported, as well as effect sizes (Cohen's d). RESULTS: Half (n = 67) of the sample was ADT-exposed and half (n = 66) were unexposed. The average age was 72 years, most were White, and over 50% had at least secondary education. There were no statistically significant differences between groups by age, race, or education. Unadjusted analyses showed the ADT-exposed group, compared with the ADT-unexposed group, performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.01 to <0.01), verbal recall (d = 0.33-0.54, p = 0.06 to <0.01), and possible effects in visuospatial construction (d = 0.33, p = 0.08 to 0.06). When controlling for age and education, similar patterns emerged. The ADT exposed-group performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.06 to 0.03) and verbal recall (d = 0.33-0.54, p = 0.11 to 0.03), and possible effects in visuospatial construction d = 0.33, p = 0.18 to 0.13. CONCLUSIONS: This study suggests long-term ADT exposure impacts verbal learning, verbal recall, and possibly visuospatial abilities in older men (≥65) with PCa. The potential cognitive effects of ADT should be discussed with older patients considering long-term use of ADT.

Exploring the role of cancer fatalism and engagement with skin cancer genetic information in diverse primary care patients.

OBJECTIVE: To broaden the currently limited reach of genomic innovations, research is needed to understand how psychosocial and cultural factors influence reactions to genetic testing in diverse subgroups. Cancer fatalism is important in cancer prevention and deserves theoretical and empirical attention in the context of genomics and behavior change. METHODS: The current study employed data from a randomized controlled trial (N = 593) offering skin cancer genetic testing (using the melanocortin-1 receptor [MC1R] gene) in primary care in Albuquerque, New Mexico, USA. We examined interrelations of cancer fatalism with demographics, general health beliefs, perceived risk, perceived control, sun protection and skin screening behaviors and cancer worry in the skin cancer context stratified across Hispanic versus non-Hispanic ethnicity, and examined cancer fatalism as a moderator of intervention effects on study primary outcomes, including 3-month sun protection, cancer worry and perceived risk. RESULTS: Cancer fatalism was significantly related to the perception of control over skin cancer risk behaviors (ps ≤ 0.01) and demographics (ethnicity, education, health literacy; ps < 0.05), but not consistently related to general health beliefs or risk perception. Cancer fatalism did not moderate intervention effects on primary outcomes, except those with higher cancer fatalism randomized to intervention had higher levels of 3-month cancer worry (p = 0.019). CONCLUSIONS: These findings will guide future work considering the role of cancer fatalism in use of genomic technologies in the general population. This work anticipates strategies required to address cancer fatalism as translational genomics becomes more commonly available to diverse general population subgroups.

A randomized controlled trial of a distress screening, consultation, and targeted referral system for family caregivers in oncologic care.

OBJECTIVE: Distress screening is standard practice among oncology patients, yet few routine distress screening programs exist for cancer caregivers. The objective of this study was to demonstrate the feasibility, acceptability, and preliminary efficacy of Cancer Support Source-CaregiverTM (CSS-CG, 33-item), an electronic distress screening and automated referral program with a consultation (S + C) to improve caregiver unmet needs, quality of life, anxiety, depression, and distress relative to Enhanced Usual Care (EUC; access to educational materials). METHOD: 150 caregivers of patients with varying sites/stages of cancer were randomized to S + C or EUC and completed assessments at baseline, 3-months post-baseline, and 6-months post-baseline. A subset of participants (n = 10) completed in-depth qualitative interviews. RESULTS: S + C was feasible: among 75 caregivers randomized to S + C, 66 (88%) completed CSS-CG and consultation. Top concerns reported were: (1) patient's pain and/or physical discomfort; (2) patient's cancer progressing/recurring; and (3) feeling nervous or afraid. Differences between groups in improvements on outcomes by T2 and T3 were modest (ds < 0.53) in favor of S + C. Qualitative data underscored the helpfulness of S + C in connecting caregivers to support and helping them feel cared for and integrated into cancer care. CONCLUSIONS: S + C is feasible, acceptable, and yields more positive impact on emotional well-being than usual care. Future studies will examine programmatic impact among caregivers experiencing higher acuity of needs, and benefits of earlier integration of S + C on caregiver, patient, and healthcare system outcomes.

Utilizing a patient advocacy-led clinical network to engage diverse, community-based sites in implementation-effectiveness research.

BACKGROUND: Increased engagement with community-based practices is a promising strategy for increasing clinical trials access of diverse patient populations. In this study we assessed the ability to utilize a patient-advocacy organization led clinical network to engage diverse practices as field sites for clinical research. METHODS: GO2 for Lung Cancer led recruitment efforts of 17 field sites from their Centers of Excellence in Lung Cancer Screening Network for participation in an implementation-effectiveness trial focused on smoking cessation integration into screening programs for lung cancer. Sites were engaged by one of three methods: 1) Pre-Grant submission of letters of support, 2) a non-targeted study information dissemination campaign to network members, and 3) proactive, targeted outreach to specific centers informed by previously submitted network member data. Detailed self-reported information on barriers to participation was collected from centers that declined to join the study. RESULTS: Of 17 total field sites, 16 were recruited via the targeted outreach campaign and 1 via pre-grant letter of support submission. The sites covered 13 states and 4 United States geographic regions, were varied in annual screening volumes and years of screening program experience and were predominantly community-based practices (10 of 17 sites). The most reported reason (by 33% of sites) for declining to participate as a field site was inadequate staffing bandwidth for trial activities. This was especially true in community-based programs among which it was reported by 45% as a reason for declining. CONCLUSIONS: Our results suggest that this model of field site recruitment leveraging an existing partnership between an academic research team and an informal clinical network maintained by a disease-specific patient advocacy organization can result in engagement of diverse, community-based field sites. Additionally, reported barriers to participation by sites indicate that solutions centered around providing additional resources to enable greater capacity for site staff may increase community-practice participation in research.

Geriatric Communication Skills Training Program for Oncology Healthcare Providers: a Secondary Analysis of Patient and Caregiver Outcomes.

Geriatric cancer patients and their caregivers have unique needs that make it difficult for their healthcare providers (HCPs) to effectively communicate with them. As ineffective communication can lead to negative health outcomes, it is important that oncology HCPs receive specialized training on communication with older adult patients and their caregivers. We conducted a small pilot study examining audio recordings of clinical encounters between HCPs and older adult cancer patients/caregivers and questionnaires completed by the patients and their caregivers before and after the HCPs participated in a geriatric communication skills training program. Eleven HCPs completed the 6-h Geriatric Comskil Training. Two clinic consultations with unique geriatric patients (n = 44) and their caregivers (n = 29) were recorded before and after training and coded for HCPs' use of communication skills. Patients and caregivers also completed surveys measuring their satisfaction with HCP communication and perceived empathy. Analysis of the audio recordings revealed that HCPs did not increase their use of communication skills after training. Although our sample was too small to detect statistical significance, measures of effect size showed trending improvements in patients' and caregivers' perceptions of HCPs' empathy and satisfaction with their communication after training. Our findings build on previous studies evaluating the feasibility and effectiveness of the Geriatric Comskil Training in real world setting and indicate that the training may have improved HCPs' communication with older adult patients and their caregivers even if their use of their observable communication skills did not change.

A survey of statistical methods utilized for analysis of randomized controlled trials of behavioral interventions.

OBJECTIVES: Given the many statistical analysis options used for randomized controlled trials (RCTs) of behavioral interventions and the lack of clear guidance for analysis selection, the present study aimed to characterize the predominate statistical analyses utilized in RCTs in palliative care and behavioral research and to highlight the relative strengths and weaknesses of each of these methods as guidance for future researchers and reform. METHODS: All RCTs published between 2015 and 2021 were systematically extracted from 4 behavioral medicine journals and analyzed based on prespecified inclusion criteria. Two independent raters classified each of the manuscripts into 1 of 5 RCT analysis strategies. RESULTS: There was wide variation in the methods used. The 2 most prevalent analyses for RCTs were longitudinal modeling and analysis of covariance. Application of method varied significantly by sample size. SIGNIFICANCE OF RESULTS: Each statistical analysis presents its own unique strengths and weaknesses. The information resulting from this research may prove helpful for researchers in palliative care and behavioral medicine in navigating the variety of statistical methods available. Future discussion around best practices in RCT analyses is warranted to compare the relative impact of interventions in a more standardized way.

Psychosocial well-being among patients with malignant pleural mesothelioma.

OBJECTIVES: The investigators conducted a psychosocial needs assessment of mesothelioma patients through self-report measures of quality of life (QOL), coping, depression, and social support. METHODS: Patients with malignant pleural mesothelioma (MPM) (N = 67) completed a battery of assessments at a single timepoint after being approached during routine medical oncology clinic appointments or by letter. RESULTS: Participants were predominately male (70.0%; n = 47) and ranged in age from 35 to 83 years old (M = 65.61, SD = 9.71). Most participants were white (88.0%; n = 59), and 10.0% (n = 7) were identified as Hispanic. The majority were married or living with a partner (93.0%; n = 62) and had some college or more education (64.0%; n = 43). Fourteen percent of participants (n = 11) endorsed significantly elevated depression symptoms. No significant demographic or clinical differences in depressed compared to nondepressed participants were observed, with a trend toward those identifying as Hispanic and those who were divorced as being more likely to be depressed. For the total sample, the most frequently endorsed coping strategies were active coping, emotional support, and acceptance. SIGNIFICANCE OF RESULTS: The present study did not identify any clear correlates of depression or QOL among patients with MPM. This research contributes to the small literature on psychosocial functioning in patients with MPM and provides putative directions for future larger studies and the development of interventions to provide appropriate support to diverse patients with MPM.

Decision-Making and Health-Related Quality of Life in Patients with Melanoma Considering Adjuvant Immunotherapy.

BACKGROUND: Adjuvant anti-PD1 treatment improves relapse-free survival (RFS) but has not been shown to improve overall survival (OS) in melanoma and is associated with risks of immune-related adverse events (irAEs), some permanent. We identified factors patients consider in deciding whether to undergo adjuvant anti-PD1 treatment and assessed prospective health-related quality of life (HRQoL), treatment satisfaction, and decisional regret. PATIENTS AND METHODS: Patients with stage IIIB-IV cutaneous melanoma and free of disease, were candidates for adjuvant anti-PD1 immunotherapy, and had not yet discussed adjuvant treatment options with their oncologist were eligible. Participants viewed a 4-minute informational video tailored to their disease stage which communicated comprehensive, quantitative information about the risk of relapse both with and without adjuvant treatment, and risks of each irAE before deciding whether or not to opt for adjuvant therapy. We collected data on demographics, HRQoL, and attitudes toward adjuvant treatment over 1 year. RESULTS: 14/34 patients (41%) opted for adjuvant anti-PD1 immunotherapy, 20/34 (59%) opted for observation. Patients choosing adjuvant immunotherapy scored higher on HRQoL social well-being at pre-treatment, were more likely to endorse positive statements about adjuvant immunotherapy, and to perceive that their physician preferred adjuvant therapy. They had lower decisional regret and higher satisfaction, even if they experienced toxicity or recurrence. CONCLUSIONS: When provided with comprehensive quantitative information about risks and benefits of adjuvant anti-PD1 immunotherapy, 20/34 (59%) of patients opted for observation. Patients choosing adjuvant immunotherapy had lower decisional regret and higher satisfaction over time even if they had poorer outcomes in treatment.

Associations between social COVID-19 exposure and psychological functioning.

The negative consequences of the COVID-19 pandemic on mental health have been widely reported, but less is known about how the impact of COVID-19 on others in one's social circle shapes these high distress levels. This study examines associations between social COVID-19 exposure-knowing someone who had a COVID-19 infection-and psychological functioning, as well as whether socio-demographic factors moderate these relationships. In June 2020, respondents (N = 343) from clinics in Tampa, Florida, U.S.A. reported whether they had social COVID-19 exposure, anxiety, depression, and stress, and other COVID-19-related concerns. Social COVID-19 exposure was associated with increased anxiety, stress, and concerns about a family member getting sick, and concerns about drinking and substance use. Several associations between exposure and psychological functioning were stronger in women, younger people, and people with lower income, implying these groups face elevated psychological risks due to the pandemic, and should be prioritized in mental health recovery efforts.

Lung Cancer Screening Knowledge, Attitudes, and Practice Patterns Among Primary and Pulmonary Care Clinicians.

BACKGROUND: Lung cancer screening has the potential to identify lung cancer at an early stage when more treatment options exist. However, discussions with and referrals of screening-eligible patients remain unacceptably low. We need to better understand clinician knowledge, attitudes, and practice patterns to identify strategies to improve lung cancer screening uptake. Prior studies have focused on understanding these factors from physicians only. Nevertheless, many patients receive primary care from nurse practitioners and physician assistants where prevention and early detection conversations are most likely to occur. Therefore, we must engage the full range of clinicians treating screening-eligible patients. OBJECTIVES: The aim of this study was to describe attitudes, beliefs and referral practice patterns, lung cancer screening knowledge, and concordance with lung cancer screening guidelines among nurse practitioners, physicians, and physician assistants in the United States. METHODS: A descriptive, cross-sectional study was performed using survey methodology with clinical vignettes to examine clinician factors and concordance with U.S. Preventive Services Task Force lung cancer screening guidelines. RESULTS: Participants scored low on attitudes toward shared decision-making, high on the importance of shared decision-making in lung cancer screening, and low on barriers to lung cancer screening referral. In addition, midrange scores on empathy toward patients with smoking history were noted. Lung cancer screening knowledge was low regardless of clinician specialty; the most endorsed response when presented with a hypothetical patient was to refer for lung cancer screening using a chest X-ray. DISCUSSION: Findings demonstrate that most clinicians are nonconcordant with U.S. Preventive Services Task Force guidelines, erroneously believing a chest X-ray is appropriate for lung cancer screening. Clinicians must follow evidence-based practice guidelines, highlighting the need for targeted continuing education about lung cancer screening for clinicians who treat screening-eligible patients.

Luteinizing Hormone Suppression Profiles in Men Treated With Exogenous Testosterone.

BACKGROUND: Due to the negative feedback mechanism involved in the hypothalamic-pituitary-gonadal axis, testosterone therapy (TTh) may result in suppression of luteinizing hormone (LH) secretion, but clinical experience demonstrates the level of LH suppression is variable. AIM: We sought to define the relationship between TTh and LH levels, specifically predictors of LH suppression in men on TTh. METHODS: We performed a retrospective analysis of a prospectively maintained database of patients with testosterone deficiency (TD) treated with TTh. Patient demographic and clinical data including vascular risk factor (VRF) status were collected. Serum total T and LH levels before TTh and after ≥3 months (m) were recorded. LH suppression was defined as serum LH level <1.0 IU/ml. MAIN OUTCOME MEASURES: Predictors of LH suppression were searched though a series of logistic regression models assessing suppression status at the final observation, and then a series of Cox proportional hazards models assessing time to first suppression were performed. RESULTS: A total of 227 patients with mean age of 58±14 years at time of TTh initiation were included in our analysis. Just under half of subjects received transdermal T as the only modality (n = 101, 44%), while one third (n = 77, 34%) received intramuscular only, and the remainder (n = 49, 22%) received both modalities during follow-up. The mean baseline LH level was 10 ± 12 IU/ml. The percent of men who had baseline LH level above 1 IU/ml and at any given point of TTh was 84% and 78%, respectively, thus 22% of men had suppressed LH levels on TTh considering the definition of LH <1 IU/ml. Most men (73%) had a suppressed LH level of <1 IU/ml at least once during follow-up. In the final adjusted model for LH suppression, intramuscular route (OR = 2.44), baseline LH (OR = 0.94), estradiol (OR = 1.05) remained significant. CLINICAL IMPLICATIONS: LH suppression profiles may be relevant for dose titration during TTh and perhaps to minimize testicular atrophy. STRENGTHS & LIMITATIONS: A strict definition for TD was applied using LCMS for T measurements and patients had long-term follow-up. CONCLUSION: While 73% of patients had at least one LH <1 IU/ml during TTh, only 22% maintained suppressed throughout the treatment. Miranda EP, Schofield E, Matsushita K, et al. Luteinizing Hormone Suppression Profiles in Men Treated With Exogenous Testosterone. J Sex Med 2022;19:1359-1365.

The Relationship Between PSA and Total Testosterone Levels in Men With Prostate Cancer.

BACKGROUND: Prostate-specific antigen (PSA) secretion is a testosterone (T) dependent process. Published data suggest that a low T level is an independent predictor of higher-grade prostate cancer (PC). AIM: To evaluate the relationship between T and PSA in patients with PC. METHODS: All men diagnosed with PC with a recorded pre-treatment total T level measurement were included in this analysis. We analyzed demographic, clinical, and pathological data. Patients were stratified according to pretreatment PSA levels: <2 ng/mL, 2-4 ng/mL, >4 ng/mL. Low T was defined as total T < 10.4 nmol/L (300 ng/dL), very low T < 6.9 nmol/L (200 ng/dL). OUTCOMES: T levels by PSA groups according to the PC pathology. RESULTS: In this retrospective study, mean patient age was 61 years among 646 men. The distribution by PSA group was: 8% (<2), 17% (2-4), and 76% (>4). The mean T level across the entire cohort was 13 nmol/L (374 ng/dL). Overall, 30% had a T level < 10.4 nmol/L (300 ng/dL). The mean total T level by PSA group was: <2 ng/mL, 7 nmol/L (206 ng/dL); 2-4 ng/mL, 13 nmol/L (362 ng/dL); >4 ng/mL, 14 nmol/L (393 ng/dL), P < .001. PSA <4 ng/mL was a significant predictor of low T in men with PC GS ≥8. PSA <2 ng/mL was a significant predictor of very low T independent of the PC pathology. CLINICAL IMPLICATIONS: These findings suggest that clinicians should consider measuring T levels when a patient diagnosed with PC GS ≥8 and PSA level <4 ng/mL, and for each patient with PSA level <2 ng/mL independent of the PC pathology. STRENGTHS & LIMITATIONS: Our study has several strengths including (i) inclusion of a large population of men, (ii) use of a database which is audited and reviewed for accuracy annually, and (iii) use of an accurate T assay (LCMS). Nonetheless, there are limitations: (i) the subjects of the study are from a single institution, and (ii) we did not measure free T levels. CONCLUSION: In men with PC with GS ≥8, PSA level <4 ng/mL predicts low T. PSA <2 ng/mL predicts very low T independent of the PC pathology. Flores JM, Bernie HL, Miranda E, et al. The Relationship Between PSA and Total Testosterone Levels in Men With Prostate Cancer. J Sex Med 2022;19:471-478.

Predictors of Curvature Improvement in Men With Peyronie's Disease Treated With Intralesional Collagenase Clostridium Histolyticum.

INTRODUCTION: Penile curvature is the most common abnormality that is observed by men with Peyronie's disease (PD). Collagenase Clostridium histolyticum (CCH) has become a standard treatment for PD patients. AIM: To identify predictor factors associated with improvements of penile curvature outcomes in men with PD treated with CCH. METHODS: We retrospectively collected the data of patients with PD treated with CCH up to 8 injections divided into 4 cycles between January 2014 and July 2020. Per protocol, penile curvature was assessed at baseline, and after the second and ford CCH cycle. If after cycle 2, curvature demonstrated no improvement, or penile curvature was significantly improved and the patient was happy, no further treatment was recommended. However, if penile curvature was significantly improved and the patient remained dissatisfied, 4 cycles were completed. Three categories of response were evaluated: improvement (≥10 degrees or ≥20%, either 1 happens), unchanged (±10 degrees or ±20%) or worsened (≥10 degrees or ≥20%, either 1 happens). Logistic regression analyses were performed to evaluate predictive factors associated with penile curvature improvements. OUTCOMES: Degrees of the curvature changes between the baseline and after the cycles of CCH. RESULTS: A total of 114 patients underwent CCH treatment. Median age was 57 years. Median PD duration was 11 months. At baseline, mean curvature was 47 degrees, 65% had dorsal curvature, 53% mid-shaft location, and 15% calcification. After CCH treatment, the mean final curvature was 40 degrees. A total of 44% improved the curvature, 39% had no change while 17% worsened after CCH treatment. Of men who had penile curvature improvement with CCH treatment, the mean curvature decreasing in degrees and percentage were 22 degrees and 41%, respectively. Men with baseline curvature ≤ 30, 31-59, and ≥ 60 degrees, the percentage curvature improvement were 29%, 43%, and 60%, respectively. Baseline curvature was the only significant predictor of penile curvature improvement after CCH (OR 1.33, 95% CI = 1.1, 1.7). CLINICAL IMPLICATIONS: We confirmed baseline penile curvature is the most important predictive factor, and this is the first report describing proportions of penile curvature improvement with CCH treatment. STRENGTHS AND LIMITATIONS: This study has several strengths, including the use of validated instruments. Nonetheless, there are limitations: the retrospective nature of the study, a single institution; and modelling device was not controlled. CONCLUSION: Penile curvature improvement was significantly more common in patients with greater baseline curvature, reaching up to 60% for patients with ≥ 60 degrees.

African-centered coping, resilience, and psychological distress in Black prostate cancer patients.

OBJECTIVE: Blacks have the highest incidence and mortality rates for prostate cancer (PCa) in the U.S. Black PCa patients (PCaP) also report high psychological distress. Identifying culturally specific coping strategies that lower distress among Black PCaP could help improve psychological interventions for this group. African-centered coping (strategies unique to the structure of Black personality and the African-centered worldview) have been identified. We hypothesized that these coping strategies and resilience would be associated with lower psychological distress (anxiety and depression) in Black PCaP. METHODS: Black PCaP (N = 95) completed a survey assessing African-centered coping strategies, resilience, anxiety, and depression. Multiple regression was employed to examine African-centered coping strategies and resilience as predictors of psychological distress. RESULTS: Participants were aged M = 67 ± 9 years and 52% had late-stage PCa. Twenty percent met criteria for clinically significant anxiety, and 17% for depression. African-centered coping strategies were not associated with lower anxiety or depression, while resilience was associated with decreased anxiety (r = -0.45, p < 0.001) and depression (r = -0.54, p < 0.001). Mediation analyses did not support an indirect association among African-centered coping strategies, resilience, and anxiety and depression. CONCLUSIONS: Contrary to hypotheses, African-centered coping strategies were not associated with psychological distress. However, as predicted, greater resilience was associated with lower anxiety and depression. These findings support the relevancy of resilience in Blacks' psychological adjustment to PCa. It might be worthwhile to explore African-centered coping strategies that help Black PCaP cope with distress.

Development and psychometric evaluation of the Spanish version of the lung cancer screening health belief scale.

OBJECTIVE: The aim of this study was to describe the translation and psychometric testing of the Lung Cancer Screening Health Belief Scale (LCSHBS) into Spanish. METHODS: The English version of the LCSHBS was professionally translated in accordance with best practices in the translation of patient-reported outcome tools. The independent certified professional translator completed a forward translation of the LCSHBS from English to Spanish, followed by a review of the translated questionnaire by a certified Memorial Sloan Kettering Cancer Center Spanish-English bicultural expert, who reviewed the scale for accuracy. RESULTS: Initial testing of the scales is valid and reliable, and supports the Spanish version of the LCSHBS (LCSHBS-S). Internal consistency reliability of the scales was supported with Cronbach's ranging from 0.81 to 0.96. Construct validity was established with confirmatory factor analysis and testing for differences between individuals who have and have not screened in theoretically proposed directions. These newly translated scales can help investigators expand this research into the large Spanish-speaking lung screening-eligible population as they develop and test critical behavioural interventions to increase lung cancer screening in the at-risk population. CONCLUSIONS: Development of effective interventions to enhance shared decision-making about lung cancer screening between patients and providers must first identify factors influencing the individual's screening participation. Future efforts facilitating patient-provider conversations are better informed by understanding the perspective of the individual making the decision.

Training oncology care providers in the assessment and treatment of tobacco use and dependence.

BACKGROUND: Clinical practice guidelines for promoting smoking cessation in cancer care exist; however, most oncology settings have not established tobacco use assessment and treatment as standard care. Inadequate staff training and other implementation challenges have been identified as barriers for delivery of evidence-based tobacco treatment. Providing training in tobacco treatment tailored to the unique needs of tobacco-dependent patients with cancer is one strategy to improve adoption of best practices to promote smoking cessation in cancer care. METHODS: A tobacco treatment training program for oncology care providers (tobacco treatment training-oncology [TTT-O]) consisting of a 2-day didactic and experiential workshop followed by 6 monthly, collaboratory videoconference calls supporting participants in their efforts to implement National Comprehensive Cancer Network guidelines in their oncology settings was developed and implemented. This article presents preliminary results on program evaluation, changes in participants' self-efficacy, and progress in implementing tobacco treatment. RESULTS: Data have been obtained from the first 5 cohorts of TTT-O participants (n = 110) who completed training, course evaluations, baseline and follow-up surveys. Participants rated the training as highly favorable and reported significant gains in self-efficacy in their ability to assess and treat tobacco dependence. Participants also demonstrated significant improvements in tobacco treatment skills and implementation of several indicators of improved adoption of best practices for tobacco treatment in their cancer care settings. CONCLUSIONS: Implementation of tobacco treatment training for cancer care providers is feasible, acceptable, and can have a significant positive impact on participants' tobacco treatment skills, self-efficacy, and greater adoption of tobacco treatment delivery in cancer care.

Uptake and acceptability of a mainstreaming model of hereditary cancer multigene panel testing among patients with ovarian, pancreatic, and prostate cancer.

PURPOSE: To address demands for timely germline information to guide treatments, we evaluated experiences of patients with ovarian, pancreatic, and prostate cancer with a mainstreaming genetic testing model wherein multigene panel testing was ordered by oncologists with standardized pretest patient education, and genetic counselors delivered results and post-test genetic counseling via telephone. METHODS: Among 1,203 eligible patients, we conducted a prospective single-arm study to examine patient uptake and acceptability (via self-report surveys at baseline and three weeks and three months following result return) of this mainstreaming model. RESULTS: Only 10% of eligible patients declined participation. Among 1,054 tested participants, 10% had pathogenic variants (PV), 16% had variants of uncertain significance (VUS), and 74% had no variant identified (NV). Participants reported high initial acceptability, including high satisfaction with their testing decision. Variability over time in several outcomes existed for participants with PV or NV: those with NV experienced a temporary increase in depression (pTime < 0.001; pTime2 < 0.001), and those with PV experienced a small increase in genetic testing distress (p = 0.03). Findings suggested that result type, sex, and cancer type were also associated with outcomes including clinical depression and uncertainty. CONCLUSION: This mainstreaming model may offer a feasible approach for extending access to germline genetic information.

Sildenafil Citrate and Risk of Biochemical Recurrence in Prostate Cancer Patients Treated with Radiation Therapy: Post-Hoc Analysis of a Randomized Controlled Trial.

BACKGROUND: Sildenafil citrate has been shown to be protective of sexual function when given concurrently and following prostate radiation therapy (RT), but some evidence suggests an increased biochemical recurrence (BCR) risk in patients taking sildenafil after radical prostatectomy. AIM: To evaluate whether sildenafil use is associated with increased risk of BCR in patients receiving prostate RT, we performed a secondary analysis of a randomized placebo-controlled trial (RPCT) that compared sildenafil citrate to placebo during and after prostate RT. METHODS: The study population consisted of prostate cancer patients who initiated radiation treatment at our institution and participated in our multi-institutional RPCT that compared 6 months of sildenafil 50 mg once a day to placebo with a 24-month follow-up. Androgen deprivation therapy (ADT) was allowed. Prostate cancer prognostic risk grouping was not an exclusion criterion, but most study participants had low- or intermediate-risk prostate cancer. Statistical analysis was performed using Kaplan-Meier plots and log-rank testing. OUTCOMES: The primary outcomes of this report were biochemical recurrence and overall survival rates, where BCR was defined according to the Phoenix definition. RESULTS: Data of 162 men were analyzed. Nine men had inadequate PSA follow-up and the remaining 153 men were included in the final report. Median age was 61 years. At a median follow-up of 8.3 years (range: 3.0-12.2), 5/94 (5.3%) and 2/59 (3.4%) patients developed BCR in the sildenafil and placebo groups, respectively. The 6-year BCR-free survival was 98.8% for all patients, 98.1% for the sildenafil cohort, and 100% for the placebo cohort. The 10-year BCR-free survival was 94.4% for all patients, 95.6% for the sildenafil cohort, and 92.9% for the placebo cohort. There was no difference in BCR-free survival between the sildenafil and placebo groups by log-rank comparison (p = 0.36). CLINICAL IMPLICATIONS: This analysis informs clinical decision making about the safety of using sildenafil during and after prostate RT. STRENGTHS AND LIMITATIONS: This study included patients who were treated in the setting of a prospective, randomized placebo-controlled trial, and who attained high medication compliance. However, the study was limited by the post-hoc nature of the analysis, use of ADT in some patients, inadequate study power to detect a difference in BCR between sildenafil and placebo groups. CONCLUSION: Prophylactic sildenafil citrate was not associated with biochemical recurrence risk in prostate cancer patients treated with radiation. However, the study was inadequately powered to definitively conclude a negative finding.
