Higher area deprivation index is associated with poorer local control and overall survival in non-metastatic nasopharyngeal carcinoma.

BACKGROUND: Neighborhood socioeconomic deprivation impacts outcomes in various cancers. We examined this association in nasopharyngeal carcinoma (NPC) patients using the area deprivation index (ADI). METHODS: We conducted a single-institution retrospective cohort study on NPC patients treated with definitive radiotherapy from 1980 to 2023. ADI was used as the primary exposure measure. Higher ADI indicates higher levels of socioeconomic deprivation. RESULTS: Of 561 patients, those with higher ADI (6-10 vs. 1-5) presented more commonly with AJCC stage III/IV compared to I/II (87% vs. 76%, p = 0.03). Increasing ADI decile score correlated with poorer overall survival (HR 1.14, 95% CI 1.01-1.28, p = 0.04). Local control was worse in patients from the most deprived quartile in the cohort ADI 5-10 (HR 2.11, 95% CI 1.01-4.41, p = 0.05). CONCLUSIONS: NPC patients from more disadvantaged neighborhoods undergoing radiotherapy had worse local control and survival outcomes. Interventions to address structural determinants of health and neighborhood disparities may improve these outcomes.

Evaluation of Culture Conducive to Academic Success by Gender at a Comprehensive Cancer Center.

INTRODUCTION: The primary objective of this study was to determine whether workplace culture in academic oncology differed by gender, during the COVID-19 pandemic. MATERIALS AND METHODS: We used the Culture Conducive to Women's Academic Success (CCWAS), a validated survey tool, to investigate the academic climate at an NCI-designated Cancer Center. We adapted the CCWAS to be applicable to people of all genders. The full membership of the Cancer Center was surveyed (total faculty = 429). The questions in each of 4 CCWAS domains (equal access to opportunities, work-life balance, freedom from gender bias, and leadership support) were scored using a 5-point Likert scale. Median score and interquartile ranges for each domain were calculated. RESULTS: A total of 168 respondents (men = 58, women = 106, n = 4 not disclosed) submitted survey responses. The response rate was 39% overall and 70% among women faculty. We found significant differences in perceptions of workplace culture by gender, both in responses to individual questions and in the overall score in the following domains: equal access to opportunities, work-life balance, and leader support, and in the total score for the CCWAS. CONCLUSIONS: Our survey is the first of its kind completed during the COVID-19 pandemic at an NCI-designated Cancer Center, in which myriad factors contributed to burnout and workplace challenges. These results point to specific issues that detract from the success of women pursuing careers in academic oncology. Identifying these issues can be used to design and implement solutions to improve workforce culture, mitigate gender bias, and retain faculty.

Ctrl-C: a cross-sectional study of the electronic health record usage patterns of US oncology clinicians.

Despite some positive impact, the use of electronic health records (EHRs) has been associated with negative effects, such as emotional exhaustion. We sought to compare EHR use patterns for oncology vs nononcology medical specialists. In this cross-sectional study, we employed EHR usage data for 349 ambulatory health-care systems nationwide collected from the vendor Epic from January to August 2019. We compared note composition, message volume, and time in the EHR system for oncology vs nononcology clinicians. Compared with nononcology medical specialists, oncologists had a statistically significantly greater percentage of notes derived from Copy and Paste functions but less SmartPhrase use. They received more total EHR messages per day than other medical specialists, with a higher proportion of results and system-generated messages. Our results point to priorities for enhancing EHR systems to meet the needs of oncology clinicians, particularly as related to facilitating the complex documentation, results, and therapy involved in oncology care.

The role of adjuvant radiation therapy in older patients with node-positive vulvar cancer: A national cancer database analysis.

OBJECTIVE: We sought to evaluate whether the survival benefit of adjuvant radiotherapy in patients with node-positive vulvar cancer is maintained in older patients, who comprise a large subgroup of patients with vulvar cancer. METHODS: The National Cancer Database (NCDB) was queried for patients aged 65 years or older, who were diagnosed with vulvar squamous cell carcinoma from 2004 to 2017 and underwent surgery with confirmed node-positive disease. Statistical analysis was performed with propensity-score matching, chi-square test, log-rank test, Kaplan-Meier, and multivariable Cox proportional regression. RESULTS: A total of 2396 patients were analyzed, and 1517 (63.3%) received adjuvant radiotherapy. Median follow-up was 73 months. Median age at diagnosis was 77 years (range 65-90). In the propensity score-matched cohort, five-year overall survival (OS) was 29%. Five-year OS was 33% in patients who received surgery followed by adjuvant radiotherapy and 26% in patients who received surgery alone (p < 0.0001). Multivariable analysis continued to demonstrate a survival benefit associated with the addition of adjuvant radiotherapy (OR 0.77 [95% CI 0.69-00.87], p < 0.001). Adjuvant radiotherapy was associated with improved OS among patients aged 65-84 (5-year OS 35% vs 29%, p = 0.0004), but not in patients aged 85 years and older (5-year OS 20% vs 19%, p = 0.32). CONCLUSION: This NCDB study suggests that in older patients with node-positive vulvar cancer, radiotherapy continues to be a vital component of multimodality therapy. However, a comprehensive and geriatrics-specific approach is crucial for treating older adults with node-positive vulvar cancer, as the benefit of adjuvant radiotherapy may be compromised by treatment-related morbidity/toxicity.

Epidemiology of Breast Cancer Presentation in Botswana, South Africa, and the United States.

INTRODUCTION: This study sought to compare the clinicopathologic features of women with breast cancer presenting in South Africa, Botswana, and the United States (US). METHODS: Breast cancer samples from Botswana (n = 384, 2011-2015), South Africa (n = 475, 2016-2017), and the US (n = 361,353, 2011-2012) were retrospectively reviewed. RESULTS: The median age of sub-Saharan African women presenting with breast cancer (age 54 in Botswana and South Africa) was younger than that of those in the US (age 61) (P < 0.001). Sub-Saharan women were more likely to present with advanced stage disease than US counterparts (64.7% in Botswana, 63.3% in South Africa, 13% in the US, P < 0.001). Triple negative disease was highest in Botswana (21.3%) compared to South Africa (11.4%) and the US (12.94%) (P < 0.001). Differences in receptor status at presentation among the three cohorts (P < 0.001) were not observed when the cohorts were stratified by ethnicity. Black/multiracial patients in Botswana and the US were the most likely subsets to present with the adverse characteristic of triple negative disease (21.3% and 23.2%, respectively). No correlation was found between HIV and receptor status in the Botswana (P = 0.513) or South African (P = 0.352) cohorts. CONCLUSIONS: Here we report receptor status patterns at presentation in Botswana and South Africa. This study reveals important similarities and differences which may inform policy and provide context for future epidemiologic trends of breast cancer in low- and-middle-income countries particularly in sub-Saharan Africa.

Better late than never: Brachytherapy is more important than timing in treatment of locally advanced cervical cancer.

PURPOSE: To evaluate the utilization of brachytherapy and duration of treatment on overall survival for locally advanced cervical cancer. METHODS: The National Cancer Database (NCDB) was queried to identify stage II-IVA cervical cancer patients diagnosed in the United States between 2004 and 2015 who were treated with definitive chemoradiation therapy. We defined standard of care (SOC) treatment as receiving external beam radiation therapy (EBRT) and concurrent chemotherapy, brachytherapy (BT), and completing treatment within 8 weeks, and compared SOC treatment to non-SOC. The primary outcome was overall survival (OS). We also evaluated the effect of sociodemographic and clinical variables on receiving SOC. RESULTS: We identified 10,172 women with locally advanced cervical cancer primarily treated with chemotherapy and concurrent EBRT of which 6047 (59.4%) patients received brachytherapy, and only 2978 (29.3%) completed treatment within 8 weeks (SOC). Receipt of SOC was associated with significantly improved overall survival (median OS 131.0 mos vs 95.5 mos, 78.1 mos, 49.2 mos; p < 0.0001). Furthemore, in patients whose treatment extended beyond 8 weeks, brachytherapy was still associated with an improved survival (median OS 95.5 vs 49.2 mos, p < 0.0001). More advanced stage, Non-Hispanic Black race, lower income, lack of insurance or government insurance, less education, and rural residence were associated with decreased likelihood of receiving SOC. CONCLUSIONS: Completing standard of care concurrent chemoradiation therapy and brachytherapy in the recommended 8 weeks was associated with a superior overall survival. Patients who received brachytherapy boost show superior survival to patients receiving EBRT alone, regardless of treatment duration. Disparities in care for vulnerable populations highlight the challenges and importance of care coordination for patients with cervical cancer.

Brain Metastases in EGFR- and ALK-Positive NSCLC: Outcomes of Central Nervous System-Penetrant Tyrosine Kinase Inhibitors Alone Versus in Combination With Radiation.

INTRODUCTION: Management of central nervous system (CNS) metastases in patients with driver-mutated NSCLC has traditionally incorporated both tyrosine kinase inhibitors (TKIs) and intracranial radiation. Whether next generation, CNS-penetrant TKIs can be used alone without upfront radiation, however, remains unknown. This multi-institutional retrospective analysis aimed to compare outcomes in patients with EGFR- or ALK-positive NSCLC who received CNS-penetrant TKI therapy alone versus in combination with radiation for new or progressing intracranial metastases. METHODS: Data were retrospectively collected from three academic institutions. Two treatment groups (CNS-penetrant TKI alone versus TKI + CNS radiation therapy) were compared for both EGFR- and ALK-positive cohorts. Outcome variables included time to progression, time to intracranial progression, and time to treatment failure, measured from the date of initiation of CNS-penetrant TKI therapy. RESULTS: A total of 147 patients were included (EGFR n = 94, ALK n = 52, both n = 1). In patients receiving radiation, larger metastases, neurologic symptoms, and receipt of steroids were more common. There were no significant differences between TKI and CNS radiation therapy plus TKI groups for any of the study outcomes, including time to progression (8.5 versus 6.9 mo, p = 0.13 [EFGR] and 11.4 versus 13.4 mo, p = 0.98 [ALK]), time to intracranial progression (14.8 versus 20.5 mo, p = 0.51 [EGFR] and 18.1 versus 21.8 mo, p = 0.65 [ALK]), or time to treatment failure (13.8 versus 8.6 mo, p = 0.26 [EGFR] and 13.5 versus 23.2 mo, p = 0.95 [ALK]). CONCLUSIONS: These results provide preliminary evidence that intracranial activity of CNS-penetrant TKIs may enable local radiation to be deferred in appropriately selected patients without negatively affecting progression.

Interprofessional Education Curriculum for Medical Assistants in Radiation Oncology: A Single Institution Pilot Program.

PURPOSE: Medical assistants (MAs) occupy an increasingly prevalent role in the clinical setting. Subspecialized fields such as oncology require specific clinical knowledge; however, MAs have few requirements for continued education. Here we assess the role and effect of a pilot MA Radiation Oncology education curriculum. METHODS AND MATERIALS: A needs assessment survey was conducted and reviewed to develop a comprehensive introductory oncology curriculum. A resident physician-led program was implemented in an academic cancer care center consisting of monthly, 1-hour lectures. Pre- and postlecture surveys were administered to assess learning. Quarterly surveys were conducted over the 20-month curriculum timeframe. RESULTS: The needs assessment revealed that there were no pre-existing MA continuing education didactics, but all (100%) MAs surveyed were "very interested" in such a curriculum. Sessions were found to be clear, comprehensive, relevant, and associated with a significant increase in a sense of empowerment (P = .035). Topics in Head and Neck and Breast Cancer showed large improvements in understanding (change in median Likert score of 3-4 points each) whereas topics in Introduction to Oncology and New Patient Consultation showed the smallest change (change 0.5-1). For 20 months, there was a sustained improvement in clinical understanding within and outside the scope of the MA role and an improvement in perceived empathy for patients (from median Likert score 3.5-5). CONCLUSIONS: Dedicated education programs for MAs show the potential to improve clinical understanding and participation in patient care. Further studies may demonstrate how such programs translate to staff productivity or patient clinical outcomes. Interprofessional education may facilitate collaboration and enhanced clinical workflow.

Implementation and Impact of a Store-and-Forward Teledermatology Platform in an Urban Academic Safety-Net Health Care System.

Background:Minority and low-income patients disproportionately experience dermatologic access challenges. Store-and-forward (SAF) teledermatology has emerged as a model of care delivery that may improve access. We sought to evaluate patterns of utilization and overall impact after SAF teledermatology implementation in a safety-net health care system. Methods:We performed a retrospective review of 3,285 teledermatology consultations from 2014 to 2017 in an urban academic safety-net health care system. Results:A total of 1,680 (51.2%) patients were referred for inflammatory/rash conditions and 967 (29.5%) for skin lesions. The teledermatologist recommended in-person evaluation in 1,199 encounters (36.5%). Median wait time for a subsequent appointment was 36 days (range 0-244 days). Of subsequent in-clinic visits, 237 patients (26.4%) underwent skin biopsy. No-show rate after referral was 11.8%. In comparison, median wait time for dermatology appointment through standard referral was 64 days, with a no-show rate of 18.6%. Biopsy rate of patients referred via teledermatology was 26.4%, in comparison to a rate of 10.9% of patients referred directly from primary care provider. Discussion:Implementation of SAF teledermatology in a safety-net health system resulted in avoidance of 63.5% potential dermatology visits. Consultation typically resulted in a change in suspected diagnosis or management plan. Rates of concordance between teledermatology consults and in-person evaluations were high. Median wait time was reduced by almost half, no-show rate was reduced ∼37%, and biopsy rate was more than double for teledermatology patients compared with standard referral. Conclusion:These findings suggest that SAF teledermatology may improve access to high-quality dermatologic care and increase clinic efficiencies for patients in safety-net health care systems.

Adjuvant radiation followed by chemotherapy is associated with improved overall survival in endometrial cancer.

OBJECTIVE: Although multimodality therapy has been shown to improve outcomes for patients with high-risk endometrial carcinoma, optimal type and timing of adjuvant therapies is unknown. METHODS: Patients with stage I-IVA endometrial carcinoma diagnosed from 2004 to 2015, and treated with surgery, chemotherapy, and radiation were identified in the National Cancer Database. Adjuvant treatment was categorized as sequential radiation followed by chemotherapy (RT-CT), concurrent chemoradiation (CCRT, RT and CT started within 7 days), or sequential chemotherapy followed by radiation (CT-RT). Analysis for propensity score matched (PSM) cohorts comparing RT-CT to CCRT and CT-RT groups was additionally performed. RESULTS: A total of 17,070 patients were identified, including 12,402 (72.7%) treated with RT-CT, 2,153 (12.6%) with CCRT, and 2,515 (14.7%) with CT-RT. Median follow-up was 44.3 months. Five-year overall-survival (OS) by adjuvant treatment regimen was 77.3% (95% CI 76.4%-78.2%), 74.3% (95% CI 72.0%-76.3%), and 74.4% (95% CI 72.5%-76.3%), respectively (p < .001). When unmatched cohorts were stratified by stage, adjuvant RT-CT was associated with improved OS in stage I and III patients. A similar survival advantage associated with RT-CT was observed in PSM cohorts comparing RT-CT group to CCRT/CT-RT group (5-year OS 77.4% vs 74.2%, p = .001). However, the difference in OS was significant only among stage III patients (RT-CT 73.9% compared to CCRT/CT-RT 69.7%, p =.002). CONCLUSION: Our findings suggest survival benefit with adjuvant RT-CT compared to CT-RT or CCRT in patients undergoing trimodality therapy for endometrial cancer. This survival benefit may be limited to stage III patients.

Association of Neurosurgical Resection With Development of Pachymeningeal Seeding in Patients With Brain Metastases.

IMPORTANCE: Neurosurgical resection represents an important management strategy for patients with large, symptomatic brain metastases and increasingly is followed by stereotactic radiation as opposed to whole-brain radiation. Whether neurosurgical resection is associated with tumor spread beyond the resection site and adjuvant stereotactic radiation field remains unknown. OBJECTIVE: To characterize the association and incidence of pachymeningeal seeding with neurosurgical resection in patients with brain metastases treated with adjuvant stereotactic radiation. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of a consecutive sample of patients with newly diagnosed brain metastases managed with neurosurgical resection and stereotactic radiation (n = 318) vs radiation alone (n = 870) between 2001 and 2015. MAIN OUTCOMES AND MEASURES: Incidence of pachymeningeal seeding (dural and/or outer arachnoid) and leptomeningeal disease in patients treated with neurosurgical resection and stereotactic radiation vs radiation alone and the risk factors and outcomes associated with pachymeningeal seeding in patients treated with neurosurgical resection followed by stereotactic radiation. RESULTS: In 1188 patients with newly diagnosed brain metastases, 133 men and 185 women (mean [SD] age, 58.9 [11.5] years) underwent neurosurgical resection. Resection was found to be associated with pachymeningeal seeding (36 of 318 patients vs 0 of 870 patients; P < .001) but not leptomeningeal disease (hazard ratio [HR], 1.14; 95% CI, 0.73-1.77; P = .56). In total, 36 (8.4%) of 428 operations were complicated by pachymeningeal seeding, with a higher incidence noted with resection of previously irradiated vs unirradiated metastases (HR, 2.39; 95% CI, 1.25-4.57; P = .008). Patients with pachymeningeal seeding had relatively low rates of subsequent development of new brain metastases and leptomeningeal disease (8 [16%] of 51 and 6 [13%] of 48, respectively). Among patients with pachymeningeal seeding, neurologic death primarily owing to progressive pachymeningeal disease accounted for 26 (72%) of 36 deaths, but when treated with salvage radiation, 49.1% of patients survived 1 year or longer. CONCLUSIONS AND RELEVANCE: In the era of omission of adjuvant whole-brain radiation after neurosurgical resection, pachymeningeal seeding beyond the stereotactic radiation field represents a notable oncologic event that often proves difficult to salvage. However, in some patients, disease control can be achieved with radiotherapeutic approaches.

Transfusion in Head and Neck Cancer Patients Undergoing Pedicled Flap Reconstruction.

OBJECTIVE: Blood product utilization is monitored to prevent unnecessary transfusions. Head-and-neck pedicled flap reconstruction transfusion-related outcomes were assessed. METHODS: One hundred and thirty-six pedicled flap patients were reviewed: 64 supraclavicular artery island flaps (SCAIF), 57 pectoralis major (PM) flaps, and 15 submental (SM) flaps. Outcome parameters included flap-related complications, medical complications, length of stay (LOS), and flap survival. Multivariable logistic regression analyses were performed. Multivariable logistic regression analyses were performed to adjust for relevant pre- and perioperative factors. RESULTS: Of all head-and-neck pedicled flap patients included in our analyses (n = 136), 40 (29.4%) received blood transfusions. The average pretransfusion hematocrit (Hct) was 24.3% ± 0.5%, with 2.65 ± 0.33 units transfused and a posttransfusion Hct increase of 5.0% ± 0.6%. Transfusion rates differed with PM (47.4%), SCAIF (17.2%), and SM (13.3%) flaps (P < 0.005). Patients undergoing PM reconstruction trended toward higher transfusion requirements (PM 2.89 ± 0.47 units, SC 2.18 ± 0.28 units, and SM 2.00 ± 0.0 units), with transfusion occurring later in the postoperative course (4.9 ± 1.3 days vs. 2.4 ± 0.1 days for all other flaps; P = 0.08). Infection, dehiscence, fistula, or medical complications were not different. Transfusion thresholds of Hct < 21 versus Hct < 27 exhibited no difference in LOS, flap-survival, or medical/flap-related complications. CONCLUSION: Transfusion is not associated with surgical or medical morbidity following head and neck pedicled flap reconstruction. There were no differences in outcomes between transfusion triggers of Hct < 21 versus Hct < 27, suggesting that a more conservative transfusion trigger may not precipitate adverse patient complications. Our data recapitulate findings in free flap patients and warrant further investigation of transfusion practices in head and neck flap reconstruction. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:E409-E415, 2018.

Ancestral Adeno-Associated Virus Vector Delivery of Opsins to Spiral Ganglion Neurons: Implications for Optogenetic Cochlear Implants.

Optogenetics is a transformative technology based on light-sensitive microbial proteins, known as opsins, that enable precise modulation of neuronal activity with pulsed radiant energy. Optogenetics has been proposed as a means to improve auditory implant outcomes by reducing channel interaction and increasing electrode density, but the introduction of opsins into cochlear spiral ganglion neurons (SGNs) in vivo has been challenging. Here we test opsin delivery using a synthetically developed ancestral adeno-associated virus (AAV) vector called Anc80L65. Wild-type C57BL/6 mouse pups were injected via the round window of cochlea with Anc80L65 carrying opsin Chronos under the control of a CAG promoter. Following an incubation of 6-22 weeks, pulsed blue light was delivered to cochlear SGNs via a cochleosotomy approach and flexible optical fiber. Optically evoked auditory brainstem responses (oABRs) and multiunit activity in inferior colliculus (IC) were observed. Post-experiment cochlear histology demonstrated opsin expression in SGNs (mean = 74%), with an even distribution of opsin along the cochlear basal/apical gradient. This study is the first to describe robust SGN transduction, opsin expression, and optically evoked auditory electrophysiology in neonatal mice. Ultimately, this work may provide the basis for a new generation of cochlear implant based on light.

Association of Androgen Deprivation Therapy and Thromboembolic Events: A Systematic Review and Meta-analysis.

OBJECTIVES: To investigate the association of androgen deprivation therapy (ADT) for prostate cancer with thromboembolic events. METHODS: PubMed, Web of Science, and Scopus were queried on April 5, 2017 for systematic review. Additionally, The World Health Organization International Trials Registry Platform was queried on June 23, 2017. Eligible studies reported thromboembolic events among individuals with prostate cancer exposed to ADT vs a lesser-exposed group. Five hundred sixty-nine unique studies were identified with 65 undergoing full-text review. We utilized the Meta-analysis of Observational Studies in Epidemiology statement guidelines and the Cochrane Review Group's data extraction template. Study quality was evaluated by Newcastle-Ottawa Scale criteria. We conducted random-effects meta-analyses to calculate summary statistic risk ratios and 95% confidence intervals. Heterogeneity was quantified using the I2 statistic. Small study effects were evaluated using Begg and Egger statistics. RESULTS: In 10 studies "ADT without estrogen" increased the risk of thromboembolic events (risk ratio [RR] 1.43, 95% confidence interval [CI] 1.15-1.77, P = .001). In 9 studies estrogen therapy alone was associated with an increased risk of thromboembolic events (RR 3.72, 95% CI 1.78-7.80, P <.001). We found an increased risk of thromboembolic events from ADT use without estrogen when limited to localized disease (RR 1.10, 95% CI 1.05-1.16, P <.001). Heterogeneity was resolved in those studies examining localized disease. There was no evidence of small study effects. CONCLUSION: The currently available evidence suggests that ADT without estrogen is associated with an increased the risk of thromboembolic events.

Characteristics and national trends of patients receiving treatment of the primary tumor for metastatic prostate cancer.

BACKGROUND: We sought to determine temporal trends in the receipt of prostatectomy or locoregional radiation to the prostate for patients with metastatic prostate cancer and to identify predictors of receipt of local treatment. METHODS: We identified 39,976 patients with metastatic prostate cancer diagnosed in 2004-2012 using the National Cancer Database (NCDB). We used logistic multivariable regression to determine trends in the receipt of prostate and/or pelvic radiation or radical prostatectomy after adjusting for demographic and clinical factors. RESULTS: Patients with metastatic disease were less likely to receive locoregional treatment over time [7.88% in 2004 vs. 5.53% in 2012, adjusted odds ratio (AOR) = 0.97 per year, 95% confidence interval (CI) = 0.95-0.98; P < 0.001]. Cofactors associated with decreased likelihood for locoregional treatment included older age (AOR = 0.96 per year, 95% CI = 0.96-0.96, P < 0.001) and increased comorbidity level (1 comorbidity: AOR = 0.82, 95% CI = 0.73-0.93, P = 0.001; two or more comorbidities: AOR = 0.49, 95% CI = 0.39-0.61, P < 0.001). Decreasing utilization of both radiation and surgery of the primary site contributed to this trend. More specifically, patients with metastatic disease were less likely to receive radiation to the prostate and/or pelvis over time (5.9% in 2004 vs. 4.2% in 2012, AOR = 0.97 per year, 95% CI = 0.95-0.99, P < 0.001). Similarly, there was a trend toward decreased use of radical prostatectomy (2.17% in 2004 compared to 1.31% in 2012, AOR = 0.96 per year, 95% CI 0.93-0.99, P = 0.01). CONCLUSION: Despite recent evidence of the possible benefit for locoregional treatment of prostate cancer in the setting of metastatic disease, rates of prostate radiation and radical prostatectomy among this population have actually declined over the 8-year period between 2004 and 2012, suggesting slow adoption of this novel treatment paradigm.

Association of androgen deprivation therapy and depression in the treatment of prostate cancer: A systematic review and meta-analysis.

BACKGROUND: There is increasing evidence that androgen deprivation therapy (ADT) may be associated with depression. Existing studies have shown conflicting results. METHODS: PubMed, Web of Science, Embase, and PsycINFO were queried on April 5, 2017. Eligible studies were in English and reported depression among individuals with prostate cancer exposed to a course of ADT vs. a lesser-exposed group (e.g., any-ADT vs. no ADT and continuous ADT vs. intermittent ADT). We used the MOOSE statement guidelines and the Cochrane Review Group's data extraction template. Study quality was evaluated by Newcastle-Ottawa Scale criteria. We conducted a random-effects meta-analysis to calculate summary statistic risk ratios (RRs) and 95% CIs. Heterogeneity was quantified using the I2 statistic and prespecified subgroup analysis. Small study effects were evaluated using Begg and Egger statistics. RESULTS: A total of 1,128 studies were initially identified and evaluated. A meta-analysis of 18 studies among 168,756 individuals found that ADT use conferred a 41% increased risk of depression (RR = 1.41; 95% CI: 1.18-1.70; P<0.001). We found a consistent strong statistically significant association when limiting our analysis to studies in localized disease (RR = 1.85; 95% CI: 1.20-2.85; P = 0.005) and those using a clinical diagnosis of depression (RR = 1.19; 95% CI: 1.08-1.32; P = 0.001). We did not find an association for continuous ADT with depression risk compared to intermittent ADT (RR = 1.00; 95% CI: 0.50-1.99; P = 0.992). There was no statistically significant evidence of small study effects. Statistically significant heterogeneity in the full analysis (I2 = 80%; 95% CI: 69-87; P<0.001) resolved when examining studies using a clinical diagnosis of depression (I2 = 16%; 95% CI: 0-60; P = 0.310). CONCLUSION: The currently available evidence suggests that ADT in the treatment of prostate cancer is associated with an increased risk of depression.

Update on Surgical Outcomes of Lateral Temporal Bone Resection for Ear and Temporal Bone Malignancies.

Objectives Review outcomes of lateral temporal bone resections for ear and temporal bone malignancy. Design, Setting, and Participants Retrospective review of all lateral temporal bone resections performed from 2008 to 2015 at a single tertiary care center. Main Outcome Measures Patient demographics, perioperative variables, overall survival, disease-free survival (DFS), and comparison of Kaplan-Meier curves. Results Overall, 56 patients were identified with a mean follow-up period of 2.3 ± 1.8 years. The predominant histopathologic diagnosis was squamous cell carcinoma (SCC, 54%), followed by salivary gland tumors (18%), and basal cell carcinoma (9%). Tumor stages were T1-T2 in 23%, T3-T4 in 73%, and two unknown primary lesions. Mean overall survival was 4.6 ± 0.4 years. Comparison of tumors with and without lymph node involvement or perineural invasion approached statistical significance for overall survival (p = 0.07 and 0.06, respectively). DFS was 2.5 ± 0.3 years. Stratification by lymph node status had a statistically significant difference in DFS (p = 0.03). Subgroup analysis of SCC patients did not reveal significant differences. Conclusions Based on our cohort, most patients with temporal bone malignancies present with advanced disease, making it difficult to achieve negative margins. Overall, lymph node status was the strongest predictor of survival in this group.
