Longitudinal Trends in Patient-Reported Outcomes in the First Year After Lumpectomy Versus Mastectomy.

BACKGROUND: It is unclear how patient-reported outcomes (PROs) change longitudinally after breast cancer surgery. We sought to compare trends in PROs among patients who underwent lumpectomy versus mastectomy over the first year after surgery. PATIENTS AND METHODS: Newly diagnosed stage 0-III female patients with breast cancer who underwent lumpectomy or mastectomy at an academic breast center between June 2019 and March 2023 were invited to participate in a longitudinal PRO study. Enrolled patients received the BREAST-Q™ module, a validated tool measuring domains, such as satisfaction with breasts, psychosocial well-being, physical well-being, and sexual well-being. Scores for each domain were compared between the lumpectomy and mastectomy groups over the first year after surgery. Linear mixed models were used to estimate the change in PRO scores over time. RESULTS: The cohort included 203 who underwent lumpectomy and 144 who underwent mastectomy. Patients who underwent lumpectomy were older, more likely to receive adjuvant radiation and endocrine therapy, and less likely to receive adjuvant chemotherapy. Patients who underwent lumpectomy demonstrated greater increases in scores over time for satisfaction with breasts, psychosocial well-being, and sexual well-being compared with patients who underwent mastectomy, after adjusting for the abovementioned covariates and receipt of reconstruction. The lumpectomy group had a larger decline in physical well-being over time compared with the mastectomy group. CONCLUSIONS: Patients who underwent lumpectomy demonstrated greater satisfaction with their breasts, psychosocial well-being, and sexual well-being but worse physical well-being over the first year after surgery compared with patients who underwent mastectomy. These results may help inform early-stage breast cancer patients making decisions about their surgical care.

Breast Cancer Surgery: A Qualitative Exploration of Concerns Over Time.

INTRODUCTION: As outcomes for breast cancer patients improve, addressing the side effects and distress of treatment can optimize survivorship. Although distress in breast cancer is well known in literature, there is a lack of information on how these concerns change through the phases of the cancer care continuum. Therefore, this study investigates the longitudinal trajectory of worry in patients with nonmetastatic breast cancer. METHODS: Female patients with newly diagnosed stage I-III breast cancer comprised a mixed-methods, longitudinal study at a cancer center from June 2019 to June 2023. Patients completed an open-ended survey regarding their top three concerns. Responses were obtained before surgery and two weeks, three, six, nine months, and one year postoperatively. Responses were qualitatively coded and analyzed to determine themes of cancer-related distress. RESULTS: Participants (n = 262) were aged an average 57.53 y (±12.54), 65.8% had stage I disease at diagnosis, and 91.1% were White. Responses revealed that patients' top three sources of concerns varied by treatment phase. Overall, patients were worried about their cancer diagnosis and the risk of recurrence. Preoperatively, patients were worried about treatment timeline, while postoperative concerns transitioned to physical appearance and surgical side effects. CONCLUSIONS: Breast cancer patients consistently reported worries about cancer diagnosis, recurrence, and metastasis as well as the side effects and fear of treatments. However, patient worry appeared to be intrinsically linked with their treatment phase. Therefore, support and interventions should be catered to reflect the changing patterns of patients' sources of distress to optimize breast cancer patients' quality of life.

Assessing Diagnostic Accuracy of Four-dimensional CT for Instable Scapholunate Dissociation: The Prospective ACTION Trial.

Background Timely treatment of scapholunate instability depends on early identification, but current imaging methods are either intricate or fail to demonstrate the dynamic stages. Purpose To calculate the diagnostic accuracy of four-dimensional (4D) CT for diagnosing instable scapholunate ligament (SLL) tears. Materials and Methods This prospective study enrolled consecutive participants with clinically suspected SLL tears who underwent 4D CT from July 2020 to May 2022. A historical study sample diagnosed at cineradiography served as a comparison, and wrist arthroscopy was the reference standard. Scapholunate joints greater than 3 mm were interpreted as instable at index 4D CT and cineradiography. Diagnostic accuracy was expressed as sensitivity and specificity. Areas under the receiver operating characteristic curve and cutoff values for both index tests were calculated. Intraclass correlation coefficients (ICCs) were computed to compare interrater reliability. Effective radiation doses at 4D CT were measured with thermoluminescent dosimeters. Results The study included 40 participants (mean age, 43 years ± 14 [SD]; 24 male) evaluated at 4D CT and 78 patients (mean age, 45 years ± 11; 50 male) historically evaluated at cineradiography. Four-dimensional CT helped detect instable tears in 26 of 35 participants (sensitivity, 74.3% [95% CI: 56.7, 87.5]. Cineradiography revealed instable tears in 52 of 63 patients (sensitivity, 82.5% [95% CI: 70.9, 91]). Four of five participants with stable scapholunate joints were identified at 4D CT (specificity, 80.0% [95% CI: 28.4, 99.5]), and 12 of 15 patients with stable SLLs were identified at cineradiography (specificity, 80.0% [95% CI: 51.9, 95.7]). Interrater agreement of radiologic measurements on 4D CT scans was good to excellent (ICC range, 0.89-0.96). The effective radiation dose ranged from 67 to 72 mSv at the wrist and was less than 1 mSv at the head. Conclusion Four-dimensional CT results are highly reproducible. Instable scapholunate joints greater than 3 mm were detected with a sensitivity of 74.3% and a specificity of 80% in an exploratory trial. Further evidence from larger randomized trials is warranted.

Postoperative Outcomes After Staged Versus Coordinated Breast Surgery and Bilateral Salpingo-Oophorectomy.

BACKGROUND: The objective of this study was to compare postoperative complication rates and healthcare charges between patients who underwent coordinated versus staged breast surgery and bilateral salpingo-oophorectomy (BSO). PATIENTS AND METHODS: The MarketScan administrative database was used to identify adult female patients with invasive breast cancer or BRCA1/BRCA2 mutations who underwent BSO and breast surgery (lumpectomy or mastectomy with or without reconstruction) between 2010 and 2015. Patients were assigned to the coordinated group if a breast operation and BSO were performed simultaneously or assigned to the staged group if BSO was performed separately. Primary outcomes were (1) incidence of 90-day postoperative complications and (2) 2-year aggregate perioperative healthcare charges. Fisher's exact tests, Wilcoxon rank-sum tests, and multivariable regression analyses were performed. RESULTS: Of the 4228 patients who underwent breast surgery and BSO, 412 (9.7%) were in the coordinated group and 3816 (90.3%) were in the staged group. The coordinated group had a higher incidence of postoperative complications (24.0% vs. 17.7%, p < 0.01), higher risk-adjusted odds of postoperative complications [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.06-1.76, p = 0.02], and similar aggregate healthcare charges before (median charges: $106,500 vs. $101,555, p = 0.96) and after risk-adjustment [incidence rate ratio (IRR) 1.00, 95% CI 0.93-1.07; p = 0.95]. In a subgroup analysis, incidence of postoperative complications (12.9% for coordinated operations vs. 11.7% for staged operation, p = 0.73) was similar in patients whose breast operation was a lumpectomy. CONCLUSIONS: While costs were similar, coordinating breast surgery with BSO was associated with more complications in patients who underwent mastectomy, but not in patients who underwent lumpectomy. These data should inform shared decision-making in high-risk patients.

Robot-assisted retroperitoneal lymph node dissection: a systematic review of perioperative outcomes.

OBJECTIVE: To assess the safety and feasibility of robot-assisted retroperitoneal lymph node dissection (R-RPLND) and to compare the perioperative outcomes of R-RPLND with open RPLND (O-RPLND), as RPLND forms an integral part of the management of testis cancer and R-RPLND is a minimally invasive treatment option for this disease. MATERIALS AND METHODS: The PubMed® , Scopus® , Cochrane Central Register of Controlled Trials, and Web of Science™ databases were searched for studies reporting perioperative outcomes of primary and post-chemotherapy R-RPLND and studies comparing R-RPLND with O-RPLND. RESULTS: The search yielded 42 articles describing R-RPLND, including five comparative studies. The systematic review included 4222 patients (single-arm studies, n = 459; comparative studies, n = 3763). Of 459 patients in the single-arm studies, 271 underwent primary R-RPLND and 188 underwent post-chemotherapy R-RPLND. For primary R-RPLND, the operative time ranged from 175 to 540 min and the major complication rate was 4.1%. For post-chemotherapy R-RPLND, the operative time ranged from 134 to 550 min and the major complication rate was 8.5%. The conversion rate to open surgery was 2.2% in primary R-RPLND and 9.0% in post-chemotherapy R-RPLND. In comparison with O-RPLND, R-RPLND was associated with a lower transfusion rate (14.5% vs 0.9%, P < 0.001) and a lower complication rate (18.5% vs 7.8%, P = 0.002). CONCLUSION: Robot-assisted RPLND has acceptable perioperative outcomes in both the primary and post-chemotherapy settings but a notable rate of conversion to open surgery in the post-chemotherapy setting. Compared with O-RPLND, R-RPLND is associated with a lower transfusion rate and fewer overall complications. Given the potential impact of selection bias, the optimal patient selection criteria for R-RPLND remain to be elucidated.

Financial Toxicity of Breast Cancer Care: The Patient Perspective Through Surveys and Interviews.

INTRODUCTION: Although the economic burden of cancer care is an emerging concern in the United States, the potential financial toxicity of breast cancer care at the patient level remains poorly understood. This study aims to characterize the scope of the contributors to financial distress on breast cancer patients and the resources utilized to address them. METHODS: Adult female patients diagnosed with invasive breast cancer or ductal carcinoma in situ between 2014 and 2019 at a single institution were retrospectively evaluated. Those who enrolled in copay assistance or indicated financial concerns on an intake distress screen were provided a web-based survey assessing financial changes, resources used, and financial engagement with providers. Semi-structured interviews further explored sources of financial distress and were analyzed by two researchers using grounded theory methodology. RESULTS: Sixty-eight patients completed the online survey, 15 of the 68 also participated in semi-structured phone interviews. On the online survey 74% of participants endorsed a financial distress score ≥5 on a scale of 0-10. Seventy-four percent changed their budget, 72% used their savings, and 60% cut down on spending. However, only 40% used resources such as financial counseling or financial assistance. Interviews revealed three major contributors to financial distress: (1) unexpected medical and nonmedical expenses, (2) lost revenue from missed work, and (3) altered budgeting. CONCLUSIONS: Many breast cancer patients experience significant financial distress without access to the resources they need. This study highlights the need for financial transparency, supportive financial services counseling at the time of diagnosis, throughout treatment and beyond.

Access to Results of Patient Reported Outcome Surveys Does Not Improve Survey Response Rates.

INTRODUCTION: In this embedded substudy of a longitudinal, randomized controlled trial, we sought to evaluate the effects of patient engagement and results feedback on longitudinal patient-reported outcome (PRO) survey completion rates. METHODS: Newly diagnosed stage 0-III breast cancer patients seen at an academic breast center between June 2019 and December 2021 were invited to participate in a longitudinal PRO study. Participants were emailed the BREAST-Q survey, a validated PRO scale, preoperatively and at regular intervals during their postoperative course. Patients were randomized into the intervention group, who received survey results upon completion, or the control group, who received no feedback. The primary endpoint was postoperative survey completion rate. An intention to treat analysis was performed and a quasi-Poisson regression was used to compare rates of longitudinal survey completion between the two groups. RESULTS: Of the 253 patients offered the preoperative survey, 115 were in the intervention group and 138 were in the control group. Postoperative survey completion rate was 54% for the intervention group and 47% for the control group. There was no significant difference in longitudinal postoperative survey completion rate between the two groups (rate ratio 1.10; 95% confidence interval [CI] 0.93-1.31). CONCLUSIONS: In this prospective randomized controlled study, patients did not complete surveys at a higher rate when their survey results were shared with them, suggesting that viewing these results without appropriate clinical context does not generate significant enhancement in patient engagement. Effective interventions to improve survey response rate must be identified to better evaluate PROs.

Lessons learned from conducting the first cancer care delivery trial in the Alliance for Clinical Trials in Oncology (Alliance A191402CD).

INTRODUCTION: Testing healthcare delivery interventions in rigorous clinical trials is a critical step in improving patient care, but conducting multisite randomized clinical trials to test the effect of care delivery interventions has unique challenges and requires foresight and planning. METHODS: We conducted the first care delivery trial (A191402CD) in the Alliance for Clinical Trials in Oncology, a National Cancer Institute Community Oncology Research Program research base, which tested the effectiveness of two different decision aids for supporting shared decision-making about prostate cancer treatment. Our experience illustrates the kind of challenges that confront care delivery researchers as they seek to test interventions to improve the experiences of patients. RESULTS: Lessons learned include the following: cluster-randomized designs introduce complexity; workflow disruption can discourage site participation; evidence-based methods may not always be sufficient. CONCLUSION: We conclude with the following recommendations: assessing feasibility requires special rigor; relationships and interpersonal dynamics must be leveraged. Our experiences may inform future care delivery research.

Decision aids for localized prostate cancer in diverse minority men: Primary outcome results from a multicenter cancer care delivery trial (Alliance A191402CD).

BACKGROUND: Decision aids (DAs) can improve knowledge for prostate cancer treatment. However, the relative effects of DAs delivered within the clinical encounter and in more diverse patient populations are unknown. A multicenter cluster randomized controlled trial with a 2×2 factorial design was performed to test the effectiveness of within-visit and previsit DAs for localized prostate cancer, and minority men were oversampled. METHODS: The interventions were delivered in urology practices affiliated with the NCI Community Oncology Research Program Alliance Research Base. The primary outcome was prostate cancer knowledge (percent correct on a 12-item measure) assessed immediately after a urology consultation. RESULTS: Four sites administered the previsit DA (39 patients), 4 sites administered the within-visit DA (44 patients), 3 sites administered both previsit and within-visit DAs (25 patients), and 4 sites provided usual care (50 patients). The median percent correct in prostate cancer knowledge, based on the postvisit knowledge assessment after the intervention delivery, was as follows: 75% for the pre+within-visit DA study arm, 67% for the previsit DA only arm, 58% for the within-visit DA only arm, and 58% for the usual-care arm. Neither the previsit DA nor the within-visit DA had a significant impact on patient knowledge of prostate cancer treatments at the prespecified 2.5% significance level (P = .132 and P = .977, respectively). CONCLUSIONS: DAs for localized prostate cancer treatment provided at 2 different points in the care continuum in a trial that oversampled minority men did not confer measurable gains in prostate cancer knowledge.

De-implementation of Axillary Dissection in Women With Breast Cancer is Largely Driven By Site-level Contextual Effects.

OBJECTIVE: To assess the contribution of unknown institutional factors (contextual effects) in the de-implementation of cALND in women with breast cancer. SUMMARY OF BACKGROUND DATA: Women included in the National Cancer Database with invasive breast carcinoma from 2012 to 2016 that underwent upfront lumpectomy and were found to have a positive sentinel node. METHODS: A multivariable mixed effects logistic regression model with a random intercept for site was used to determine the effect of patient, tumor, and institutional variables on the risk of cALND. Reference effect measureswere used to describe and compare the contribution of contextual effects to the variation in cALND use to that of measured variables. RESULTS: By 2016, cALND was still performed in at least 50% of the patients in a quarter of the institutions. Black race, younger women and those with larger or hormone negative tumors were more likely to undergo cALND. However, the width of the 90% reference effect measures range for the contextual effects exceeded that of the measured site, tumor, time, and patient demographics, suggesting institutional contextual effects were the major drivers of cALND de-implementation. For instance, a woman at an institution with low-risk of performing cALND would have 74% reduced odds of havinga cALND than if she was treated at a median-risk institution, while a patient at a high-risk institution had 3.91 times the odds. CONCLUSION: Compared to known patient, tumor, and institutional factors, contextual effects had a higher contribution to the variation in cALND use.

No One-Size-Fits-All: Sexual Health Education Preferences in Patients with Breast Cancer.

BACKGROUND: Using explanatory mixed methods, we characterize the education that patients with breast cancer received about potential sexual health effects of treatment and explore preferences in format, content, and timing of education. PATIENTS AND METHODS: Adult patients with stage 0-IV breast cancer seen at an academic breast center during December 2020 were emailed questionnaires assessing sexual health symptoms experienced during treatment. Patients interested in further study involvement were invited to participate in semistructured interviews. These interviews explored sexual health education provided by the oncology team and patient preferences in content, format, and timing of education delivery. RESULTS: Eighty-seven (32%) patients completed the questionnaire. Most patients reported decreased sexual desire (69%), vaginal dryness (63%), and less energy for sexual activity (62%) during/after treatment. Sixteen patients participated in interviews. Few women reported receiving information about potential sexual effects of breast cancer treatment; patients who did reported a focus on menopausal symptoms or fertility rather than sexual function. Regarding preferences in format, patients were in favor of multiple options being offered rather than a one-size-fits-all approach, with particular emphasis on in-person options and support groups. Patients desired education early and often throughout breast cancer treatment, not only about sexual side effects but also on mitigation strategies, sexual function, dating and partner intimacy, and body image changes. CONCLUSION: Few patients received information about the sexual health effects of breast cancer treatment, though many experienced symptoms. Potential adverse effects should be discussed early and addressed often throughout treatment, with attention to strategies to prevent and alleviate symptoms and improve overall sexual health.

Low cardiopulmonary fitness is associated with higher liver fat content and higher gamma-glutamyltransferase concentrations in the general population - "The Sedentary's Liver".

BACKGROUND: We investigated the association between low cardiorespiratory fitness and liver fat content (LFC) in the general population. MATERIALS AND METHODS: We evaluated data from 2151 adults (51.1% women) from two population-based cohorts of the Study of Health in Pomerania (SHIP-2 and SHIP-TREND-0). We analysed the cross-sectional associations of peak oxygen uptake (VO2peak ) with LFC, assessed by magnetic resonance imaging proton density fat fraction, as well as serum gamma-glutamyltransferase (GGT) and aminotransferase concentrations by multivariable regression models. RESULTS: We observed significant inverse associations of VO2peak with LFC and serum GGT, but not with serum aminotransferase levels. Specifically, a 1 L/min lower VO2peak was associated with a 1.09% (95% confidence interval [CI]: 0.45-1.73; P = .002) higher LFC and a 0.18 µkatal/L (95% CI: 0.09-0.26; P < .001) higher GGT levels. The adjusted odds ratio (OR) for the risk of prevalent hepatic steatosis (HS) by a 1 L/min decrease in VO2peak was 1.61 (95% CI: 1.22-2.13; P = .001). Compared to subjects with high VO2peak , obese and overweight individuals with low VO2peak had 1.78% (95% CI: 0.32-3.25; P = .017) and 0.94% (95% CI: 0.15-1.74; P = .021) higher mean LFC, respectively. Compared to those with high VO2peak , low VO2peak was independently associated with a higher risk of prevalent HS in the obese (adjusted-OR 2.29, 95% CI=1.48-3.56; P < .001) and overweight (adjusted OR 1.57, 95% CI=1.16-2.14; P = .04) groups. CONCLUSIONS: Lower VO2peak was significantly associated with greater LFC and higher serum GGT levels in a population-based cohort of adult individuals. Our results suggest that low VO2peak might be a risk factor for HS.

Emergency department visits for radiation cystitis among patients with a prostate cancer history.

OBJECTIVES: To elucidate the national burden of emergency department (ED) visits for radiation cystitis (RC), a known complication of radiation therapy (RT) to the pelvic area, among patients with a prostate cancer history, and identify those who are at increased risk of requiring invasive measures. PATIENTS AND METHODS: This study queried the Nationwide Emergency Department Sample for all ED visits from January 2006 to December 2015 with a primary diagnosis of RC and secondary diagnosis of prostate cancer. ED visits were characterised by demographic factors, socioeconomic factors, and hospital characteristics. Weighted frequencies were used to create national estimates for all data analysis. RESULTS: A weighted total of 17 382 ED visits occurred for RC among patients with a prostate cancer history, of which 9655 (55.5%) were treated with an invasive procedure. Notable factors associated with undergoing an invasive procedure included having a prior prostatectomy (odds ratio [OR] 5.48, 95% confidence interval [CI] 2.62-11.46), urinary retention (OR 1.35, 95% CI 1.12-1.64), haematuria (OR 1.20, 95% CI 1.01-1.42), and undergoing a blood transfusion (OR 2.12, 95% CI 1.72-2.62). ED visits that were associated with invasive procedures had a higher median total charge ($34 707.53 vs $15 632.53) and an increased median length of stay (5 vs 3 days) compared to visits without an invasive procedure. CONCLUSIONS: Among ED visits for RC in prostate cancer, approximately one half required an invasive procedure for treatment. While RT remains an effective modality for patients with prostate cancer, providers should be mindful of RC as a potential complication.

Surgeon Perceptions of the Integration of Patient-Reported Outcome Measures into Clinical Practice.

INTRODUCTION: Patient-reported outcome measures (PROMs/PROM) are standardized, validated instruments used to measure the patient's perception of their own health status including their symptoms, functional wellbeing, and mental health. Although PROMs were initially developed as research tools, their use in clinical practice for shared decision-making and to assess the impact of disease and treatment on quality of life of individual patients has been increasing. There is a paucity of research exploring providers' perspectives on the clinical integration of PROMs. We sought to use a qualitative methodology to understand surgeons' perceptions of integrating PROMs into their clinical practices. METHODS: Semistructured interviews were performed from November 2019 until August 2020. All interviews were recorded and transcribed verbatim. Thematic saturation was achieved after interviewing nine surgeons representing eight surgical specialties. Qualitative interview data were thematically analyzed using an inductive approach facilitated by Atlas.ti qualitative software. RESULTS: Forty seven unique codes were identified that fit into 21 themes that revealed five novel insights. Key insights included: (1) PROM data can modify surgical practice on an individual and institutional level, (2) Surgeon's view PROM clinical integration as a potential method of advancing patient-centered care, (3) There are various institutional processes that must be in place, including strong leadership and an integrative platform, to enable successful clinical PROM integration, (4) Surgeons appreciate challenges of integrating PROMs into surgical practice including risks of incorrect use or interpretation, and (5) A PROM platform must be adaptable to the diversity within surgery and to unique physician workflows. CONCLUSIONS: Surgeons perceived value from integrating PROMs into routine care to better inform patients during preoperative discussions and to help identify at-risk patients in the postoperative period. However, they also identified numerous barriers to the implementation of an integrated system for the routine use of PROMs in clinical practice and expressed concern about using PROMs to compare operative outcomes between surgeons. Based on this work, institutions that want to incorporate PROMs into surgical practice need a leadership team capable of supporting the change management necessary for effective integration and use a PROM platform that gives individual surgeons and surgical teams the ability to customize platforms for their unique practices.

Race, Decisional Regret and Prostate Cancer Beliefs: Identifying Targets to Reduce Racial Disparities in Prostate Cancer.

PURPOSE: African American men are more likely to be diagnosed with, die of and experience decisional regret about their prostate cancer than nonAfrican American men. Although some clinical discrepancies may be attributed to genetic risk and/or access to care, explanations for racial discrepancies in decisional regret remain largely speculative. We aim to identify sources of prostate cancer decisional regret with a focus on racial disparities. MATERIALS AND METHODS: A cohort of 1,112 patients with localized prostate cancer treated at the Cleveland Clinic between 2010 and 2016 were matched by race, Gleason score, treatment (external beam radiation, brachytherapy, prostatectomy, active surveillance), prostate specific antigen at diagnosis, age at treatment and time since treatment. All patients received 4 surveys, including the Expanded Prostate Cancer Index Composite (EPIC) 26, the Decisional Regret Scale, our novel Prostate Cancer Beliefs Questionnaire and a modified EPIC demographics form. Descriptive and comparative statistics and multivariable logistic regression were used to compare survey outcomes by race and treatment method. RESULTS: Of 1,048 deliverable surveys 378 (36.07%) were returned. African American men had worse decisional regret than nonAfrican American men even after adjusting for relevant covariates (OR 2.46, p <0.0001). African American men also had higher Prostate Cancer Beliefs Questionnaire medical mistrust and masculinity scores, both of which predicted worse decisional regret independent of race (1.415 and 1.350, p=0.0001, respectively). CONCLUSIONS: African American men suffer worse decisional regret than nonAfrican American men, which may be partially explained by higher medical mistrust and concerns about masculinity as captured by the Prostate Cancer Beliefs Questionnaire. This novel survey may facilitate identifying targets to reduce racial disparities in prostate cancer.

Choosing Between Mastectomy and Breast-Conserving Therapy: Is Patient Distress an Influencing Factor?

BACKGROUND: Breast-conserving therapy (BCT) offers oncologic outcomes similar to those of mastectomy, yet many patients, when provided the option, choose mastectomy. This study aimed to evaluate the relationship between patient-reported distress and surgical decisions and to determine factors predictive of choosing BCT versus mastectomy. METHODS: Patients with newly diagnosed breast cancer deemed candidates for BCT who completed a distress screen at their initial visit to an academic institution between 2016 and 2019 were retrospectively reviewed. This screening tool captures distress in emotional, social, health, and practical domains on a scale of 0 to 10. The distress scores were compared against surgical decisions using nonparametric Wilcoxon rank-sum tests. Patient factors associated with surgical choice were analyzed using chi-square, Fisher's exact, and Student's t tests. A two-sided p value lower than 0.05 was considered significant. RESULTS: Of 506 patients deemed eligible for BCT, 430 (85%) chose BCT and 76 (15%) pursued mastectomy. The distress levels did not differ significantly between the surgical options. The patients who underwent mastectomy were on the average younger (50.7 vs 60.4 years; p < 0.0001), presented with palpable masses (p < 0.0001), had stage 0, 2, or 3 versus stage 1 disease (p < 0.0001), sought consultation for second opinions (19.7% vs 8.6%; p = 0.0032), received neoadjuvant chemotherapy (31.6% vs 16.3%; p = 0.0016), or had deleterious gene mutations (21.1% vs 5.1%; p < 0.0001). CONCLUSIONS: Distress was not associated with the pursuit of surgical treatment. Rather, younger age, search for a second opinion, and a palpable mass present at presentation were associated with more aggressive surgical decisions. Understanding factors that influence surgical decision-making is critical in guiding informed decisions that reflect patient values.

Early Trajectories of Patient Reported Outcomes in Breast Cancer Patients Undergoing Lumpectomy Versus Mastectomy.

PURPOSE: This study was designed to: (1) characterize longitudinal patient-reported outcomes (PROs) between breast cancer patients undergoing lumpectomy and mastectomy and (2) compare return to baseline scores at 3 months and 6 months postoperatively. METHODS: Newly diagnosed breast cancer patients seen at an academic breast center between June 2019 and February 2021 were invited to participate in longitudinal PRO surveys at their initial clinic visit. If willing to participate, patients were emailed the validated BREAST-Q™ questionnaire at the initial clinic visit (baseline), 2 weeks after surgery, and then every 3 months for the first year. We used linear mixed models to estimate the differences in slopes over time between lumpectomy and mastectomy for each PRO measure. Pearson's Chi-square tests with Yates' continuity correction were used to compare proportions of patients who return to baseline PRO scores. P < 0.05 was considered significant. RESULTS: Of 164 patients invited to participate, 100 (61%) completed a baseline survey and were included in analyses. Mastectomy patients had significantly greater decreases in breast satisfaction (P = 0.002), psychosocial well-being (P < 0.0001), and sexual well-being (P < 0.0001) over time compared with lumpectomy patients. Both surgical groups reported a decrease in physical well-being, although the decline was more significant in lumpectomy patients (P = 0.005). At 3 months and 6 months after surgery, significantly larger proportions of lumpectomy patients returned to their baseline breast satisfaction, psychosocial well-being, and physical well-being compared with mastectomy patients. CONCLUSIONS: Understanding how outcomes important to patients change over the care continuum can provide opportunities for early intervention and may prevent debilitating long-term morbidities of treatment.

National trends in the management of patients with positive surgical margins at radical prostatectomy.

PURPOSE: To evaluate practice patterns of planned post-operative radiation therapy (RT) among men with positive surgical margins (PSM) at radical prostatectomy. METHODS: We identified 43,806 men within the National Cancer Database with pathologic node-negative prostate cancer diagnosed in 2010 through 2014 with PSM. The primary endpoint was receipt of planned (RT) within a patient's initial course of treatment. We examined post-RP androgen deprivation therapy (ADT) with RT as a secondary endpoint. We evaluated patterns of post-operative management and characteristics associated with planned post-prostatectomy RT. RESULTS: Within 12 months of RP, 87.0% received no planned RT, 8.5% RT alone, 1.3% ADT alone, and 3.1% RT with ADT. In a multivariable logistic regression model, planned RT use was associated with clinical and pathologic characteristics as estimated by surgical Cancer of the Prostate Risk Assessment (CAPRA-S) category (intermediate versus low, OR = 2.87, 95% CI 2.19-3.75, P < 0.001; high versus low, OR = 10.23, 95% CI 7.79-13.43, P < 0.001), treatment at community versus academic centers (OR = 1.24, 95% CI 1.15-1.34, P < 0.001), shorter distance to a treatment facility (OR = 0.97 for each 10-mile, 95% CI 0.96-0.98, P < 0.001), and uninsured status (OR = 1.39, 95% CI 1.10-1.77, P = 0.005). The odds of receiving planned RT were lower in 2014 versus 2010 (OR = 0.76, 95% CI 0.68-0.85, P < 0.001). There was no significant change in the use of ADT with RT. High versus low CAPRA-S category was associated with the use of ADT in addition to RT (OR = 5.13, 95% CI 1.57-16.80, P = 0.007). CONCLUSION: The use of planned post-prostatectomy RT remained stable among patients with PSM and appears driven primarily by the presence of other adverse pathologic features.

Neutral-layer-free directed self-assembly of block copolymer in trench using capillary force-induced meniscus.

We propose trench-directed self-assembly (TDSA) of a block copolymer (BCP) driven by a capillary force-induced meniscus as a facile scalable nanolithography method. Unlike conventional directed self-assembly methods, TDSA enables the achievement of neutral surface-free vertical orientations of the BCP nanopatterns irrespective of the polarizability of the substrate, which may be, for example, a ceramic (SiO2) on Semiconductor (Si). In our demonstration of the proposed method, we generated various morphologies of the BCP nanopatterns by varying the trench width, and molecular weight of the BCP. The proposed TDSA method is potentially advantageous for the design of a process/device layout required for the development of an effective manufacturing process.

Supercritical fluid extraction-supercritical fluid chromatography of saliva: Single-quadrupole mass spectrometry monitoring of caffeine for gastric emptying studies†.

Saliva is an attractive sampling matrix for measuring various endogenous and exogeneous substances but requires sample treatment prior to chromatographic analysis. Exploiting supercritical CO2 for both extraction and chromatography simplifies sample preparation, reduces organic solvent consumption, and minimizes exposure to potentially infectious samples, but has not yet been applied to oral fluid. Here, we demonstrate the feasibility and benefits of online supercritical fluid extraction coupled to supercritical fluid chromatography and single-quadrupole mass spectrometry for monitoring the model salivary tracer caffeine. A comparison of 13 C- and 32 S-labeled internal standards with external standard calibration confirmed the superiority of stable isotope-labeled caffeine over nonanalogous internal standards. As proof of concept, the validated method was applied to saliva from a magnetic resonance imaging study of gastric emptying. After administration of 35 mg caffeine via ice capsule, salivary levels correlated with magnetic resonance imaging data, corroborating caffeine's usefulness as tracer of gastric emptying (R2  = 0.945). In contrast to off-line methods, online quantification required only minute amounts of organic solvents and a single manual operation prior to online bioanalysis of saliva, thus demonstrating the usefulness of CO2 -based extraction and separation techniques for potentially infective biomatrices.
