RESUMEN

BACKGROUND: While males present with more adverse clinicopathologic features in papillary thyroid carcinoma (PTC), younger age has previously been shown to be a favorable prognostic factor. We examined the combined effect of male sex and young age on PTC outcomes. METHODS: We conducted a retrospective analysis of a prospectively maintained database of thyroid cancer surgery patients (2000-2020) at a single quaternary care institution. We included papillary thyroid carcinoma cases and excluded those with prior cancer-related thyroid surgery. We examined demographics, cancer stage, surgical outcomes, and complications by age and sex, analyzing groups below and above the age of 40 years. RESULTS: A total of 680 patients with PTC were included. Females constituted 68% (age ≥40 years: 44% and <40 years: 24%) and males 32% (≥40 years: 24% and <40 years: 8%). A significant difference (p < 0.001) of N1 disease distribution was found between the groups. N1a metastasis was greater in patients younger than 40 regardless of sex ((M < 40 (15%), F < 40 (15%), M ≥ 40 (12%), and F ≥ 40 (9%)). While, M < 40 had greater N1b metastasis (36%) than all other groups (M ≥ 40 (28%), F < 40 (22%), and F ≥ 40 (10%)). There was no significant difference in the distribution of T stages between groups. Groups showed no differences in 30-day outcomes, recurrence at 1 year, reoperation, mortality, nerve injury, or hypocalcemia. CONCLUSIONS: Young males with PTC face increased occurrence of nodal metastasis yet experience similar recurrence rates as their female and older counterparts. Subgroup analysis underscores the predictive role of sex and age in advanced PTC cases.

RESUMEN

Locally advanced rectal cancer is typically treated with chemoradiotherapy followed by surgery. Most patients do not display a complete response to chemoradiotherapy, but resistance mechanisms are poorly understood. ST6GAL-1 is a sialyltransferase that adds the negatively charged sugar, sialic acid (Sia), to cell surface proteins in the Golgi, altering their function. We therefore hypothesized that ST6GAL-1 could mediate resistance to chemoradiation in rectal cancer by inhibiting apoptosis. Patient-derived xenograft and organoid models of rectal cancer and rectal cancer cell lines were assessed for ST6GAL-1 protein with and without chemoradiation treatment. ST6GAL-1 mRNA was assessed in untreated human rectal adenocarcinoma by PCR assays. Samples were further assessed by Western blotting, Caspase-Glo apoptosis assays, and colony formation assays. The presence of functional ST6GAL-1 was assessed via flow cytometry using the Sambucus nigra lectin, which specifically binds cell surface α2,6-linked Sia, and via lectin precipitation. In patient-derived xenograft models of rectal cancer, we found that ST6GAL-1 protein was increased after chemoradiation in a subset of samples. Rectal cancer cell lines demonstrated increased ST6GAL-1 protein and cell surface Sia after chemoradiation. ST6GAL-1 was also increased in rectal cancer organoids after treatment. ST6GAL-1 knockdown in rectal cancer cell lines resulted in increased apoptosis and decreased survival after treatment. We concluded that ST6GAL-1 promotes resistance to chemoradiotherapy by inhibiting apoptosis in rectal cancer cell lines. More research will be needed to further elucidate the importance and mechanism of ST6GAL-1-mediated resistance.

RESUMEN

OBJECTIVE: Hyperparathyroidism (HPT) is nearly universal in patients with end-stage kidney disease. Kidney transplantation (KT) reverses HPT in many patients, but most studies have only focused on following calcium and not parathyroid hormone (PTH) levels. We sought to study the prevalence of persistent HPT post-KT at our center and its effect on graft survival. METHODS: Patients who underwent KT from January 2015 to August 2021 were included and characterized by post-KT HPT status at the most recent follow-up: resolved (achieving normal PTH post-KT) versus persistent HPT. Those with persistent HPT were further stratified by the occurrence of hypercalcemia (normocalcemic versus hypercalcemic HPT). Patient demographics, donor kidney quality, PTH and calcium levels, and allograft function were compared between groups. Multivariable logistic regression and Cox regression with propensity score matching were conducted. RESULTS: Of 1554 patients, only 390 (25.1%) patients had resolution of renal HPT post-KT with a mean (±SD) follow-up length of 40±23 months. The median (IQR) length of HPT resolution was 5 (0-16) months. Of the remaining 1164 patients with persistent HPT post-KT, 806 (69.2%) patients had high PTH and normal calcium levels, while 358 (30.8%) patients had high calcium and high PTH levels. Patients with persistent HPT had higher parathyroid hormone (PTH) at the time of KT [403 (243-659) versus 277 (163-454) pg/mL, P <0.001] and were more likely to have received cinacalcet treatment before KT (34.9% vs. 12.3%, P <0.001). Only 6.3% of patients with persistent HPT received parathyroidectomy. Multivariable logistic regression showed race, cinacalcet use pre-KT, dialysis before KT, receiving an organ from a deceased donor, high PTH, and calcium levels at KT were associated with persistent HPT post-KT. After adjusting for patient demographics and donor kidney quality by propensity score matching, persistent HPT (HR 2.5, 95% CI 1.1-5.7, P =0.033) was associated with a higher risk of allograft failure. Sub-analysis showed that both hypercalcemic HPT (HR 2.6, 95% CI 1.1-6.5, P =0.045) and normocalcemic HPT (HR 2.5, 95% CI 1.3-5.5, P =0.021) were associated with increased risk of allograft failure when compared with patients with resolved HPT. CONCLUSION: Persistent HPT is common (75%) after KT and is associated with a higher risk of allograft failure. PTH levels should be closely monitored after kidney transplantation so that patients with persistent HPT can be treated appropriately.

RESUMEN

OBJECTIVE: To examine whether body mass index (BMI) changes modify the association between kidney donation and incident hypertension. BACKGROUND: Obesity increases hypertension risk in both general and living kidney donor (LKD) populations. Donation-attributable risk in the context of obesity, and whether weight change modifies that risk, is unknown. METHODS: Nested case-control study among 1558 adult LKDs (1976-2020) with obesity (median follow-up: 3.6 years; interquartile range: 2.0-9.4) and 3783 adults with obesity in the Coronary Artery Risk Development in Young Adults (CARDIA) and Atherosclerosis Risk in Communities (ARIC) studies (9.2 y; interquartile range: 5.3-15.8). Hypertension incidence was compared by donor status using conditional logistic regression, with BMI change investigated for effect modification. RESULTS: Overall, LKDs and nondonors had similar hypertension incidence [incidence rate ratio (IRR): 1.16, 95% confidence interval (95% CI): 0.94-1.43, P =0.16], even after adjusting for BMI change (IRR: 1.25, 95% CI: 0.99-1.58, P =0.05). Although LKDs and nondonors who lost >5% BMI had comparable hypertension incidence (IRR: 0.78, 95% CI: 0.46-1.34, P =0.36), there was a significant interaction between donor and >5% BMI gain (multiplicative interaction IRR: 1.62, 95% CI: 1.15-2.29, P =0.006; relative excess risk due to interaction: 0.90, 95% CI: 0.24-1.56, P =0.007), such that LKDs who gained weight had higher hypertension incidence than similar nondonors (IRR: 1.83, 95% CI: 1.32-2.53, P <0.001). CONCLUSIONS: Overall, LKDs and nondonors with obesity had similar hypertension incidence. Weight stability and loss were associated with similar hypertension incidence by donor status. However, LKDs who gained >5% saw increased hypertension incidence versus similar nondonors, providing support for counseling potential LKDs with obesity on weight management postdonation.

RESUMEN

BACKGROUND: Despite the known influences of both race- and aging-related factors in colorectal cancer outcomes and mortality, limited literature is available on the intersection between race and aging-related impairments. OBJECTIVE: To explore racial differences in frailty and geriatric deficit subdomains among patients with colorectal cancer. DESIGN: Retrospective study using data from the Cancer and Aging Resilience Evaluation registry. SETTINGS: A comprehensive cancer center in the Deep South. PATIENTS: Older adults (aged ≥60 years) with colorectal cancer. MAIN OUTCOME MEASURES: Measure of frailty and geriatric assessment subdomains of physical function, functional status, cognitive complaints, psychological function, and health-related quality of life. RESULTS: Black patients lived in areas with a higher social vulnerability index compared to White patients (0.69 vs 0.49; p < 0.01) and had limited social support more often (54.5% vs 34.9%; p = 0.01). After adjustment for age, cancer stage, comorbidities, and social vulnerability index, Black patients were found to have a higher rate of frailty than White patients (adjusted OR 3.77; 95% CI, 1.76-8.18; p = 0.01). In addition, Black patients had more physical limitations (walking 1 block: adjusted OR 1.93; 95% CI, 1.02-3.69; p = 0.04), functional limitations (activities of daily living: adjusted OR 3.21; 95% CI, 1.42-7.24; p = 0.01), and deficits in health-related quality of life (poor global self-reported health: adjusted OR 2.45; 95% CI, 1.23-5.13; p = 0.01). Similar findings were shown after stratification by stage I to III vs IV. LIMITATIONS: Retrospective study at a single institution. CONCLUSIONS: Among older patients with colorectal cancer, Black patients were more likely to be frail than White patients, with deficits observed specifically in physical function, functional status, and health-related quality of life. Geriatric assessment may provide an important tool in addressing racial inequities in colorectal cancer. DIFERENCIAS RACIALES EN LOS DFICITS RELACIONADOS CON EL ENVEJECIMIENTO ENTRE ADULTOS MAYORES CON CNCER COLORRECTAL: ANTECEDENTES: A pesar de las influencias conocidas de los factores relacionados con la raza y el envejecimiento en los resultados y la mortalidad del cáncer colorectal, hay muy poca literatura sobre la intersección entre los impedimentos relacionados con la raza y el envejecimiento.OBJETIVO: El objetivo era explorar las diferencias raciales en los subdominios de fragilidad y déficit geriátrico entre los pacientes con cáncer colorectal.DISEÑO: Estudio retrospectivo utilizando datos del registro Cancer and Aging Resilience Evaluation.AJUSTES: Un centro oncológico integral en el Sur Profundo.PACIENTES: Adultos mayores (≥60 años) con cáncer colorrectal de raza Negra o Blanca.PRINCIPALES MEDIDAS DE RESULTADO: Medida compuesta de fragilidad y subdominios de evaluación geriátrica de función física, estado funcional, quejas cognitivas, función psicológica y calidad de vida relacionada con la salud.RESULTADOS: De los 304 pacientes incluidos, el 21,7% (n = 66) eran negros y la edad media era de 69 años. Los pacientes negros vivían en áreas con un índice de vulnerabilidad social (SVI) más alto en comparación con los pacientes blancos (SVI 0,69 vs 0,49; p < 0,01) y con mayor frecuencia tenían apoyo social limitado (54,5% vs 34,9%; p = 0,01). Después de ajustar por edad, estadio del cáncer, comorbilidades y SVI, los pacientes de raza negra tenían una mayor tasa de fragilidad en comparación con los pacientes de raza blanca (ORa 3,77, IC del 95%: 1,76-8,18; p = 0,01). Además, los pacientes negros tenían más limitaciones físicas (caminar 1 cuadra: ORa 1,93, IC 95% 1,02-3,69; p = 0,04), limitaciones funcionales (actividades de la vida diaria: ORa 3,21, IC 95% 1,42-7,24; p = 0,01 ) y déficits en la calidad de vida relacionada con la salud (mala salud global autoinformada: ORa 2,45, IC 95% 1,23-5,13; p = 0,01). Las quejas cognitivas y las funciones psicológicas no difirieron según la raza (p > 0,05). Se mostraron hallazgos similares después de la estratificación por estadio I-III frente a IV.LIMITACIONES: Estudio retrospectivo en una sola institución.CONCLUSIONES: Entre los pacientes mayores con cáncer colorrectal, los pacientes negros tenían más probabilidades que los pacientes blancos de ser frágiles, observándose déficits específicamente en la función física, el estado funcional y la calidad de vida relacionada con la salud. La evaluación geriátrica puede proporcionar una herramienta importante para abordar las desigualdades raciales en el cáncer colorrectal.

RESUMEN

INTRODUCTION: Total thyroidectomy (TT) has been shown to be a safe and effective treatment for Graves' disease. However, the time course for improvement of symptoms has not been defined. METHODS: With an institutional review board approval, we prospectively gathered survey data of all patients (n = 79) undergoing TT for Graves' disease at a single institution from 2019 to 2021. After informed consent was obtained, patients completed surveys preoperatively and at 2 wk followed by monthly postoperative visits/phone calls. Patient demographics and survey results were collected and analyzed. Symptom recovery time was evaluated using Kaplan-Meier analysis. RESULTS: A total of 50 patients completed the survey on postoperative follow-up (response rate 63%). Average age was 38 y (range 12-80 y) and 88% of patients were female. The most common preoperative symptoms were fatigue (90%) and heat/cold intolerance (88%). Tremor (median time to resolution: 1 wk; interquartile range [IQR] 1-3), diarrhea (median 1 wk [IQR 1-3]), and palpitations (median 1 wk [IQR 1-3]) resolved the most rapidly followed by eye symptoms (median 3 wk [IQR 1-6]), heat/cold intolerance (median 3 wk [IQR 3-30]), memory deficits (median 3 wk [IQR 1-undefined]), and fatigue (median: 3 wk [IQR 1-14]). There were no significant differences in time to resolution of symptoms by gender or age (less than versus 40 y and older). Those with uncontrolled Graves' had more severe symptoms but no difference in time to resolution from the euthyroid Graves' patients. CONCLUSIONS: Many Graves' disease symptoms improve rapidly following TT, with a median time to improvement of less than 1 mo.

RESUMEN

BACKGROUND: Hyperparathyroidism is common in patients with end-stage kidney disease and may persist after kidney transplantation (KT). Parathyroidectomy (PTx) is curative, but whether PTx should be performed before or after KT remains controversial. There is concern that PTx can adversely affect renal allograft function if performed post-KT and result in persistent hypocalcemia. This study evaluated outcomes and postoperative complications of PTx before and after KT at our institution. METHODS: We performed a retrospective review of patients at our center (1/2012-2/2019) who had PTx either pre-KT or post-KT. Data on patient demographics, surgical outcomes, and postoperative complications of PTx were collected. RESULTS: Ninety-eight patients were included in this study, with 23 patients undergoing PTx before KT and 75 after KT. The length of follow-up after KT was 67.7 ± 25.5 months. In post-KT PTx patients, 30-day allograft function was unchanged after PTx. Calcium oxalate and phosphate crystals were less common on allograft biopsies in pre-KT PTx patients (10.0% vs. 34.8%, p = 0.038). Patients in the pre-KT group required more calcium supplementation after PTx than the post-KT group (p < 0.001). At one-year post-PTx, 17 (19.1%) patients required > 1000 mg elemental calcium per day and 7 (7.9%) patients required > 2000 mg/day. There was no difference in surgical success or postoperative complications between the two groups. CONCLUSIONS: Parathyroidectomy before or after kidney transplantation does not adversely affect allograft function. The incidence of persistent hypocalcemia was low. Parathyroidectomy is safe and effective either before or after kidney transplantation.

RESUMEN

Importance: In January 2011, the US Food and Drug Administration (FDA) announced a mandate to limit acetaminophen (paracetamol) to 325 mg/tablet in combination acetaminophen and opioid medications, with manufacturer compliance required by March 2014. Objective: To assess the odds of hospitalization and the proportion of acute liver failure (ALF) cases with acetaminophen and opioid toxicity prior to and after the mandate. Design, Setting, and Participants: This interrupted time-series analysis used hospitalization data from 2007-2019 involving ICD-9/ICD-10 codes consistent with both acetaminophen and opioid toxicity from the National Inpatient Sample (NIS), a large US hospitalization database, and ALF cases from 1998-2019 involving acetaminophen and opioid products from the Acute Liver Failure Study Group (ALFSG), a cohort of 32 US medical centers. For comparison, hospitalizations and ALF cases consistent with acetaminophen toxicity alone were extracted from the NIS and ALFSG. Exposures: Time prior to and after the FDA mandate limiting acetaminophen to 325 mg in combination acetaminophen and opioid products. Main Outcomes and Measures: Odds of hospitalization involving acetaminophen and opioid toxicity and percentage of ALF cases from acetaminophen and opioid products prior to and after the mandate. Results: In the NIS, among 474 047 585 hospitalizations from Q1 2007 through Q4 2019, there were 39 606 hospitalizations involving acetaminophen and opioid toxicity; 66.8% of cases were among women; median age, 42.2 (IQR, 28.4-54.1). In the ALFSG, from Q1 1998 through Q3 2019, there were a total of 2631 ALF cases, of which 465 involved acetaminophen and opioid toxicity; 85.4% women; median age, 39.0 (IQR, 32.0-47.0). The predicted incidence of hospitalizations 1 day prior to the FDA announcement was 12.2 cases/100 000 hospitalizations (95% CI, 11.0-13.4); by Q4 2019, it was 4.4/100 000 hospitalizations (95% CI, 4.1-4.7) (absolute difference, 7.8/100 000 [95% CI, 6.6-9.0]; P < .001). The odds of hospitalizations with acetaminophen and opioid toxicity increased 11%/y prior to the announcement (odds ratio [OR], 1.11 [95% CI, 1.06-1.15]) and decreased 11%/y after the announcement (OR, 0.89 [95% CI, 0.88-0.90]). The predicted percentage of ALF cases involving acetaminophen and opioid toxicity 1 day prior to the FDA announcement was 27.4% (95% CI, 23.3%-31.9%); by Q3 2019, it was 5.3% (95% CI, 3.1%-8.8%) (absolute difference, 21.8% [95% CI, 15.5%-32.4%]; P < .001). The percentage of ALF cases involving acetaminophen and opioid toxicity increased 7% per year prior to the announcement (OR, 1.07 [95% CI, 1.03-1.1]; P < .001) and decreased 16% per year after the announcement (OR, 0.84 [95% CI, 0.77-0.92]; P < .001). Sensitivity analyses confirmed these findings. Conclusions and Relevance: The FDA mandate limiting acetaminophen dosage to 325 mg/tablet in prescription acetaminophen and opioid products was associated with a statistically significant decrease in the yearly rate of hospitalizations and proportion per year of ALF cases involving acetaminophen and opioid toxicity.

RESUMEN

BACKGROUND: Telemedicine use has increased significantly during the COVID-19 pandemic. It remains unclear if its rapid growth exacerbates disparities in healthcare access. We aimed to characterize telemedicine use among a large oncology population in the Deep South during the COVID-19 pandemic. MATERIALS AND METHODS: A retrospective cohort study was performed at the only National Cancer Institute designated-cancer center in Alabama March 2020 to December 2020. With a diverse (26.5% Black, 61% rural) population, this southeastern demographic uniquely reflects historically vulnerable populations. All non-procedural visits at the cancer center from March to December 2020 were included in this study excluding those with a department that had fewer than 100 visits during this time period. Patient and clinic level characteristics were analyzed using t-test and Chi-square to compare characteristics between visit types (in-person versus telemedicine, and video versus audio within telemedicine). Generalized estimating equations were used to identify independent factors associated with telemedicine use and type of telemedicine use. RESULTS: There were 50 519 visits and most were in-person (81.3%). Among telemedicine visits, most were phone based (58.3%). Black race and male sex predicted in-person visits. Telemedicine visits were less likely to have video among patients who were Black, older, male, publicly insured, and from lower income areas. CONCLUSIONS: Telemedicine use, specifically with video, is significantly lower among historically vulnerable populations. Understanding barriers to telemedicine use and preferred modalities of communication among different populations will help inform insurance reimbursement and interventions at different socioecological levels to ensure the continued evolution of telemedicine is equitable.

RESUMEN

INTRODUCTION: To analyze the impact of Truth and state-sponsored anti-tobacco media campaigns on youth smoking in the United States, and their potential to reduce tobacco-related health disparities. AIMS AND METHODS: Our study included data from the 2000-2015 Monitoring the Future study, an annual nationally representative survey of youth in 8th (n = 201 913), 10th (n = 194 468), and 12th grades (n = 178 379). Our primary exposure was Gross Rating Points (GRPs) of Truth or state-sponsored anti-tobacco advertisements, from Nielsen Media Research. Modified Poisson regression was used to assess the impact of a respondent's GRPs on smoking intentions, past 30-day smoking participation, and first and daily smoking initiation. Additive interactions with sex, parental education, college plans, and race/ethnicity were used to test for differential effects of campaign exposure on each outcome. RESULTS: Greater campaign exposure (80th vs. 20th GRP percentile) was associated with lower probabilities of smoking intentions among 8th graders, smoking participation among 8th and 12th graders, and initiation among 8th graders. Greater exposure was associated with a greater reduction in the likelihood of smoking participation among 10th and 12th grade males than females; 10th and 12th graders with parents of lower education versus those with a college degree; and 12th graders who did not definitely plan to go to college relative to those who did. CONCLUSIONS: Media campaign exposure was associated with a lower likelihood of youth smoking behaviors. Associations were more pronounced for groups disproportionately affected by smoking, including youth of lower socioeconomic status. Media campaigns may be useful in reducing smoking disparities and improving health equity. IMPLICATIONS: Few recent studies have investigated the impact of anti-tobacco media campaigns on youth smoking and their potential to reduce tobacco-related health disparities in the United States. We found media campaigns-specifically state-sponsored media campaigns-reduced the likelihood of several smoking outcomes among youth, with some evidence that they mitigate disparities for disproportionately affected groups.

RESUMEN

BACKGROUND: Over time, NIH funding has become increasingly competitive. In addition, academic surgeons' research competes with time required for patient care, operating, and administrative work. Due to these competing interests for surgeons, we hypothesize that the percentage of NIH grants awarded to researchers from departments of surgery is decreasing. METHODS: The NIH Research Portfolio Online Reporting Tool was queried for the number and value of new and renewal R01 grants, and career development awards noting which surgery departments received awards from 1998 to -2018. Statistical analysis was performed using univariate and multivariable logistic regression. RESULTS: The number of career development awards granted to researchers from departments of surgery decreased significantly over time (P = 0.007) while new R01's and R01 renewal awards were stable. The number of grants awarded to researchers from all procedural departments were compared to non-procedural departments and again, career development awards decreased significantly (P = 0.005) over time but new R01's and R01 renewals stayed stable. Looking at the difference in average dollar amount received for new R01, renewal R01, or career development awards between department of surgery awardees and non-surgery over time, there was no significant difference. CONCLUSIONS: NIH funding is becoming increasingly competitive and surgeons have many competing interests. Our study found that there has been a significant decrease in career development awards to department of surgery awardees and procedural specialists. The decrease in receipt of these awards is particularly concerning given that they are meant to provide protected time for developing researchers and thus have potential consequences for future research.

RESUMEN

OBJECTIVE: This study examines the extent to which cigarette taxes affect smoking behaviour and disparities in smoking among adolescents by gender, socioeconomic status (SES) and race/ethnicity. METHODS: We used US nationally representative, repeated cross-sectional data from the 2005 to 2016 Monitoring the Future study to evaluate the relationship between state cigarette taxes and past 30-day current smoking, smoking intensity, and first cigarette and daily smoking initiation using modified Poisson and linear regression models, stratified by grade. We tested for interactions between tax and gender, SES and race/ethnicity on the additive scale using average marginal effects. RESULTS: We found that higher taxes were associated with lower smoking outcomes, with variation by grade. Across nearly all of our specifications, there were no statistically significant interactions between tax and gender, SES or race/ethnicity for any grades/outcomes. One exception is that among 12th graders, there was a statistically significant interaction between tax and college plans, with taxes being associated with a lower probability of 30-day smoking among students who definitely planned to attend college compared with those who did not. CONCLUSION: We conclude that higher taxes were associated with reduced smoking among adolescents, with little difference by gender, SES and racial/ethnicity groups. While effective at reducing adolescent smoking, taxes appear unlikely to reduce smoking disparities among youth.

RESUMEN

BACKGROUND: Partnered status is an independent predictor of clinical outcomes, including overall survival, among patients with cancer. However, the mechanisms by which partnered status impacts survival are not fully understood and to the authors' knowledge the associations between partnered status and the specific attributes of chemotherapy have not been studied to date. METHODS: The current study was an observational study of patients with resected American Joint Committee on Cancer (AJCC) stage III colon cancer diagnosed from 2008 through 2015 and recruited from an academic cancer center and 2 large community oncology practices. Outcome measures were specific attributes of adjuvant chemotherapy. Partnered status (partnered vs unpartnered) was the primary independent variable. Bivariate comparisons between independent variables and the primary outcomes were performed. Associations between partnered status and the outcomes also were analyzed using multivariable generalized estimating equations using a logit link. RESULTS: Data were collected from 436 patients. Of these patients, approximately 65% were from community oncology practices. Approximately 62% were partnered (married or living with a partner), and approximately 86% received adjuvant chemotherapy. Among these individuals, 87% received multiagent chemotherapy and 65% completed 6 months of therapy. Partnered patients were found to have a higher odds of completing chemotherapy (odds ratio, 1.98; 95% CI, 1.04-3.77). CONCLUSIONS: In this innovative investigation of the associations between partnered status and specific attributes of curative-intent chemotherapy, approximately 35% of patients terminated chemotherapy early. Having a partner increased the odds of completing therapy, which may be one mechanism through which having a partner improves disease-specific outcomes among patients with colon cancer. Identifying those aspects of partner support that can be reproduced with community or clinical personnel may help unpartnered patients to complete the recommended course of curative-intent chemotherapy.

RESUMEN

BACKGROUND: Treatment decisions for patients with early-stage breast cancer often involve discussions with multiple oncology providers. However, the extent to which primary care providers (PCPs) are involved in initial treatment decisions remains unknown. METHODS: A stratified random sample of PCPs identified by newly diagnosed patients with early-stage breast cancer from the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries were surveyed (n = 517; a 61% response rate). PCPs were asked how frequently they discussed surgery, radiation, and chemotherapy options with patients; how comfortable they were with these discussions; whether they had the necessary knowledge to participate in decision making; and what their confidence was in their ability to help (on 5-item Likert-type scales). Multivariate logistic regression was used to identify PCP-reported attitudes associated with more PCP participation in each treatment decision. RESULTS: In this sample, 34% of PCPs reported that they discussed surgery, 23% discussed radiation, and 22% discussed chemotherapy options with their patients. Of those who reported more involvement in surgical decisions, 22% reported that they were not comfortable having a discussion, and 17% did not feel that they had the necessary knowledge to participate in treatment decision making. PCPs who positively appraised their ability to participate were more likely to participate in all 3 decisions (odds ratio [OR] for surgery, 6.01; 95% confidence interval [CI], 4.16-8.68; OR for radiation, 8.37; 95% CI, 5.16-13.58; OR for chemotherapy, 6.56; 95% CI, 4.23-10.17). CONCLUSIONS: A third of PCPs reported participating in breast cancer treatment decisions, yet gaps in their knowledge about decision making and in their confidence in their ability to help exist. Efforts to increase PCPs' knowledge about breast cancer treatment options may be warranted.

RESUMEN

PURPOSE: High costs of cancer care place considerable burden on patients and society. Despite increasing recognition that providers should play a role in reducing care costs, how physicians across cancer specialties differ in their cost-consciousness has not been reported. We examined cost-consciousness regarding breast cancer care among medical oncologists, surgeons, and radiation oncologists. METHODS: We identified 514 cancer surgeons, 504 medical oncologists, and 251 radiation oncologists by patient report through the iCanCare study. iCanCare identified newly diagnosed women with breast cancer through the Surveillance, Epidemiology, and End Results (SEER) registries of Georgia and Los Angeles. We queried providers on three dimensions of cost-consciousness: (1) perceived importance of cost saving for society, patients, practice, and payers; (2) awareness of patient out-of-pocket expenses; and (3) discussion of financial burden. RESULTS: We received responses from 376 surgeons (73%), 304 medical oncologists (60%), and 169 radiation oncologists (67%). Overall levels of cost-consciousness were moderate, with scores ranging from 2.5 to 3.0 out of 5. After adjusting for covariates, surgeons had the lowest scores on all three cost-consciousness measures; medical oncologists had the highest scores. Pairwise contrasts showed surgeons had significantly lower scores than medical oncologists for all three measures and significantly lower scores than radiation oncologists for two of the three cost-consciousness variables: importance of cost saving and discussion of financial burden. CONCLUSIONS: How cost-consciousness impacts medical decision-making across specialty and how policy, structural, and behavioral interventions might sensitize providers regarding cost-related matters merit further examination.

RESUMEN

BACKGROUND: Little is known about the size and characteristics of the decision-support networks of women newly diagnosed with breast cancer and whether their involvement improves breast cancer treatment decisions. METHODS: A population-based sample of patients newly diagnosed with breast cancer in 2014 and 2015, as reported to the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries, were surveyed approximately 7 months after diagnosis (N = 2502; response rate, 68%). Network size was estimated by asking women to list up to 3 of the most important decision-support persons (DSPs) who helped them with locoregional therapy decisions. Decision deliberation was measured using 4 items assessing the degree to which patients thought through the decision, with higher scores reflecting more deliberative breast cancer treatment decisions. The size of the network (range, 0-3 or more) was compared across patient-level characteristics, and adjusted mean deliberation scores were estimated across levels of network size using multivariable linear regression. RESULTS: Of the 2502 women included in this analysis, 51% reported having 3 or more DSPs, 20% reported 2, 18% reported 1, and 11% reported not having any DSPs. Married/partnered women, those younger than 45 years, and black women all were more likely to report larger network sizes (all P < .001). Larger support networks were associated with more deliberative surgical treatment decisions (P < .001). CONCLUSIONS: Most women engaged multiple DSPs in their treatment decision making, and involving more DSPs was associated with more deliberative treatment decisions. Future initiatives to improve treatment decision making among women with breast cancer should acknowledge and engage informal DSPs. Cancer 2017;123:3895-903. © 2017 American Cancer Society.

RESUMEN

PURPOSE: Doctor-patient communication is the primary way for women diagnosed with breast cancer to learn about their risk of distant recurrence. Yet little is known about how doctors approach these discussions. METHODS: A weighted random sample of newly diagnosed early-stage breast cancer patients identified through SEER registries of Los Angeles and Georgia (2013-2015) was sent surveys about ~2 months after surgery (Phase 2, N = 3930, RR 68%). We assessed patient perceptions of doctor communication of risk of recurrence (i.e., amount, approach, inquiry about worry). Clinically determined 10-year risk of distant recurrence was established for low and intermediate invasive cancer patients. Women's perceived risk of distant recurrence (0-100%) was categorized into subgroups: overestimation, reasonably accurate, and zero risk. Understanding of risk and patient factors (e.g. health literacy, numeracy, and anxiety/worry) on physician communication outcomes was evaluated in multivariable regression models (analytic sample for substudy = 1295). RESULTS: About 33% of women reported that doctors discussed risk of recurrence as "quite a bit" or "a lot," while 14% said "not at all." Over half of women reported that doctors used words and numbers to describe risk, while 24% used only words. Overestimators (OR .50, CI 0.31-0.81) or those who perceived zero risk (OR .46, CI 0.29-0.72) more often said that their doctor did not discuss risk. Patients with low numeracy reported less discussion. Over 60% reported that their doctor almost never inquired about worry. CONCLUSIONS: Effective doctor-patient communication is critical to patient understanding of risk of recurrence. Efforts to enhance physicians' ability to engage in individualized communication around risk are needed.

RESUMEN

BACKGROUND: Usage of magnetic resonance imaging (MRI) in newly diagnosed breast cancer patients is increasing, despite scant evidence that it improves outcomes. Little is known about the knowledge, perspectives, and clinical characteristics of surgeons associated with MRI use. METHODS: Women with early-stage breast cancer undergoing definitive surgery between July 2013 and August 2015 were identified from the Los Angeles and Georgia Surveillance, Epidemiology and End Results (SEER) registries and were asked to name their attending surgeons. The 489 surgeons were sent a questionnaire; 77% (n = 377) responded. Questions that addressed the likelihood of ordering an MRI in different scenarios were used to create a scale to measure surgeon propensity for MRI use. Knowledge and practice characteristics also were assessed. RESULTS: Mean surgeon age was 54 years, 25% were female, and median number of years in practice was 21. Wide MRI use variation was observed, with 26% obtaining MRI for a clinical stage I screen-detected breast cancer and 72% for infiltrating lobular cancer. High users of MRI were significantly more likely to be higher-volume surgeons (p < 0.001) and to have misconceptions about MRI benefits (p < 0.001). Of surgeons who felt they used MRI more often, 60% were high MRI users; only 6% were low MRI users. CONCLUSIONS: Our findings suggest relatively frequent use of MRI, even in uncomplicated clinical scenarios, in the absence of evidence of benefit, and use was more common among high-volume surgeons. A substantial number of surgeons who are high MRI users harbor misconceptions about MRI benefit, suggesting an opportunity for education and consensus building regarding appropriate use.

RESUMEN

INTRODUCTION: The influence of time to surgery on racial/ethnic disparities in papillary thyroid carcinoma (PTC) survival remains unstudied. MATERIALS AND METHODS: The National Cancer Database (2004-2017) was queried for patients with localized PTC. Survival data was compared by time to surgery, patient demographics, and multivariable Cox regression was performed. RESULTS: Of 126,708 patients included, 5% were Black, 10% Hispanic. Of all patients, 85% had no comorbidities. Non-Hispanic White (NHW) patients had a shorter median time to surgery than Black and Hispanic patients (36 vs. 43 vs. 42 days, respectively p â€‹< â€‹0.001). In multivariable analysis, longer time to surgery (>90 days vs â€‹< â€‹30 days) and Black race vs NHW, were associated with worse survival (HR: 1.56, (95%CI, 1.43-1.70), p â€‹< â€‹0.001 and HR: 1.21, (1.08-1.36), p â€‹= â€‹0.001), respectively. CONCLUSION: Delaying surgery for thyroid cancer is associated with worse survival. However, independent of time to surgery and other confounders, there remains a disparity as black patients have poorer outcomes.

RESUMEN

BACKGROUND: High-grade soft tissue sarcoma is rare and associated with poor prognosis. This study examines racial and ethnic variation in presentation and outcomes at a Southeastern US cancer center. METHODS: Among an institutional cohort of patients seen between January 2016-December 2021, racial and ethnic differences were evaluated using chi-squared tests, Kaplan Meier curves, and Cox proportional hazards models. RESULTS: There were 295 patients (71 â€‹% Non-Hispanic White, 24 â€‹% Black, 3 â€‹% Hispanic White, 2 â€‹% Other). Black representation was greater than national cohorts (24 â€‹% vs. 12 â€‹%). Histological subtype varied by race/ethnicity (p â€‹= â€‹0.007). Adjusting for histology and stage, survival was worse for Black vs. White patients (HR 1.71, 95 â€‹% CI 1.07-2.76) and those with metastatic disease (5.47, 3.54-8.44). In non-metastatic patients, survival differences for Black vs. White patients were attenuated by receipt of multi-modal treatment (1.53, 0.82-2.88). CONCLUSION: Observed racial disparities in survival of high-grade sarcoma may be addressed by early, multidisciplinary management.
