Access to New Clinic Appointments for Patients With Cancer.

Importance: Racial and ethnic disparities have been observed in the outpatient visit rates for specialist care, including cancer care; however, little is known about patients' experience at the critical step of attempting to access new clinic appointments for cancer care. Objective: To determine simulated English-speaking, Spanish-speaking, and Mandarin-speaking patient callers' ability to access new clinic appointments for 3 cancer types (colon, lung, and thyroid cancer) that disproportionately impact Hispanic and Asian populations. Design, Setting, and Participants: This cross-sectional audit study was conducted between November 2021 and March 2023 using 479 clinic telephone numbers that were provided by the hospital general information personnel at 143 hospitals located across 12 US states. Using standardized scripts, trained research personnel assigned to the roles of English-speaking, Spanish-speaking, and Mandarin-speaking patients called the telephone number for a clinic that treats colon, lung, or thyroid cancer to inquire about a new clinic appointment. Data analysis was conducted from June to September 2023. Main Outcomes and Measures: The primary outcome was whether the simulated patient caller was able to access cancer care (binary variable, yes or no), which was defined to include being provided with a clinic appointment date or scheduling information. Multivariable logistic regression analysis was performed to determine factors independently associated with simulated patient callers being able to access cancer care. Results: Of 985 total calls (399 English calls; 302 Spanish calls; 284 Mandarin calls), simulated patient callers accessed cancer care in 409 calls (41.5%). Differences were observed based on language type, with simulated English-speaking patient callers significantly more likely to access cancer care compared with simulated Spanish-speaking and Mandarin-speaking patient callers (English, 245 calls [61.4%]; Spanish, 110 calls [36.4%]; Mandarin, 54 calls [19.0%]; P < .001). A substantial number of calls ended due to linguistic barriers (291 of 586 Spanish or Mandarin calls [49.7%]) and workflow barriers (239 of 985 calls [24.3%]). Compared with English-speaking simulated patient callers, the odds of accessing cancer care were lower for Spanish-speaking simulated patient callers (adjusted odds ratio [aOR], 0.34; 95% CI, 0.25-0.46) and Mandarin-speaking simulated patient callers (aOR, 0.13; 95% CI, 0.09-0.19). Compared with contacting clinics affiliated with teaching hospitals, callers had lower odds of accessing cancer care when contacting clinics that were affiliated with nonteaching hospitals (aOR, 0.53; 95% CI, 0.40-0.70). Conclusions and Relevance: In this cross-sectional audit study, simulated patient callers encountered substantial barriers when attempting to access clinic appointments for cancer care. These findings suggest that interventions focused on mitigating these barriers are necessary to increase access to cancer care for all patients.

Survival Prognostication in Patients with Differentiated Thyroid Cancer and Distant Metastases: A SEER Population-Based Study.

Background: For patients with thyroid cancer, distant metastasis is a significant predictor of poor outcome. Since distant metastasis occur in less than 10% of patients with differentiated thyroid cancer, correlates of survival in this vulnerable patient population remain understudied. This study aimed to identify prognostic groups among patients with differentiated thyroid cancer and distant metastases; and to determine the role of, and interactions between, patient and tumor characteristics in determining survival. Methods: We identified adult patients diagnosed with differentiated thyroid cancer with distant metastases from the U.S. SEER-17 cancer registry (2010-2019). Analyses were performed using Cox proportional hazards regression, survival trees, and random survival forest. Relative importance of patient and tumor factors important for disease-specific and overall survival was assessed based on the random survival forest analyses. Results: Cohort consisted of 2,411 patients with differentiated thyroid cancer with distant metastases followed for a median of 62 months. Most common histopathologic subtype (86.0%) was papillary thyroid cancer, and the most common sites of distant metastasis were the lungs (33.7%) and bone (18.9%). Cox proportional hazards model illustrated significant associations between survival and: patient age (P<0.001), tumor size (P<0.01), and site of distant metastasis (P<0.05). Survival tree analyses identified three distinct prognostic groups based on disease-specific survival (DSS) (5-year survival of the prognostic groups was 92%, 64%, and 41%; P<0.001) and four distinct prognostic groups based on overall survival (OS) (5-year survival of the prognostic groups was 96%, 84%, 57%, and 31%; P<0.001). The first split in the survival trees for DSS and OS was by age at diagnosis (<57 years vs >58 years) with subsequent splits based on presence/absence of lung metastases, tumor size (<4 cm vs >4 cm), and patient age. A total of 558 patients (23.1%) died from thyroid cancer, and 757 patients (31.4%) died from all causes during the study period. Conclusions: This study identifies distinct prognostic groups for patients with differentiated thyroid cancer with distant metastases and highlights the importance of patient age, lung metastases, and tumor size to determining both disease-specific and overall survival. These findings inform risk stratification and treatment decision-making in this understudied patient population.

Social Determinants of Health and Disparities in Thyroid Care.

BACKGROUND: There have been documented racial and ethnic disparities in the care and clinical outcomes of patients with thyroid disease. CONTEXT: Key to improving disparities in thyroid care is understanding the context for racial and ethnic disparities, which includes acknowledging and addressing social determinants of health. Thyroid disease diagnosis, treatment, and survivorship care are impacted by patient- and system-level factors, including socioeconomic status and economic stability, language, education, health literacy, and health care systems and health policy. The relationship between these factors and downstream clinical outcomes is intricate and complex, underscoring the need for a multifaceted approach to mitigate these disparities. CONCLUSION: Understanding the factors that contribute to disparities in thyroid disease is critically important. There is a need for future targeted and multilevel interventions to address these disparities, while considering societal, health care, clinician, and patient perspectives.

All-Cause and Cause-Specific Mortality Among Low-Risk Differentiated Thyroid Cancer Survivors in the United States.

Background: Despite the excellent disease-specific survival associated with low-risk differentiated thyroid cancer (DTC), its diagnosis and management have been linked to patient concerns about cancer recurrence, treatment-related health risks, and mortality. Lack of information regarding long-term health outcomes can perpetuate these concerns. Therefore, we assessed all-cause and cause-specific mortality in a large cohort of individuals diagnosed with low-risk DTC. Methods: From the U.S. Surveillance, Epidemiology, and End Results-12 cancer registry database (1992-2019), we identified 51,854 individuals (81.8% female) diagnosed with first primary DTC at low risk of recurrence (≤4 cm, localized). We estimated cause-specific cumulative mortality by time since diagnosis, accounting for competing risks. Standardized mortality ratios (SMRs) and CIs were used to compare observed mortality rates in DTC patients with expected rates in the matched U.S. general population, overall and by time since DTC diagnosis. We used Cox proportional hazards models to examine associations between radioactive iodine (RAI) treatment and cause-specific mortality. Results: During follow-up (median = 8.8, range 0-28 years), 3467 (6.7%) deaths were recorded. Thyroid cancer accounted for only 4.3% of deaths (n = 148). The most common causes of death were malignancies (other than thyroid cancer) (n = 1031, 29.7%) and cardiovascular disease (CVD; n = 912, 26.3%). The 20-year cumulative mortality rate from thyroid cancer, malignancies (other than thyroid or nonmelanoma skin cancer), and CVD was 0.6%, 4.6%, and 3.9%, respectively. Lower than expected mortality was observed for all causes excluding thyroid cancer (SMR = 0.69 [CI 0.67-0.71]) and most specific causes, including all malignancies combined (other than thyroid cancer; SMR = 0.80 [CI 0.75-0.85]) and CVD (SMR = 0.64 [CI 0.60-0.69]). However, mortality rates were elevated for specific cancers, including pancreas (SMR = 1.58 [CI 1.18-2.06]), kidney and renal pelvis (SMR = 1.85 [CI 1.10-2.93]), and brain and other nervous system (SMR = 1.62 [CI 0.99-2.51]), and myeloma (SMR = 2.35 [CI 1.46-3.60]) and leukemia (SMR = 1.62 [CI 1.07-2.36]); these associations were stronger ≥10 years after diagnosis. RAI was not associated with risk of cause-specific death, but numbers of events were small and the range of administered activities was likely narrow. Conclusions: Overall, our findings provide reassurance regarding low overall and cause-specific mortality rates in individuals with low-risk DTC. Additional research is necessary to confirm and understand the increased mortality from certain subsequent cancers.

Hidden Disparities: How Language Influences Patients' Access to Cancer Care.

BACKGROUND: Patients with limited English proficiency, a vulnerable patient population, remain understudied in the literature addressing cancer disparities. Although it is well documented that language discordance between patients and physicians negatively impacts the quality of patient care, little is known about how patients' preferred spoken language impacts their access to cancer care. PATIENTS AND METHODS: Between November 2021 and June 2022, we conducted an audit study of 144 hospitals located across 12 demographically diverse states. Using a standardized script, trained investigators assigned to the roles of English-speaking, Spanish-speaking, and Mandarin-speaking patients called the hospital general information telephone line seeking to access care for 3 cancer types that disproportionately impact Hispanic and Asian populations (colon, lung, and thyroid cancer). Primary outcome was whether the simulated patient caller was provided with the next steps to access cancer care, defined as clinic number or clinic transfer. We used chi-square tests and logistic regression analysis to test for associations between the primary outcome and language type, region type, hospital teaching status, and cancer care requested. We used multivariable logistic regression analysis to determine factors associated with simulated patient callers being provided the next steps. RESULTS: Of the 1,296 calls, 52.9% (n=686) resulted in simulated patient callers being provided next steps to access cancer care. Simulated non-English-speaking (vs English-speaking) patient callers were less likely to be provided with the next steps (Mandarin, 27.5%; Spanish, 37.7%; English, 93.5%; P<.001). Multivariable logistic regression found significant associations of the primary outcome with language spoken (Mandarin: odds ratio [OR], 0.02 [95% CI, 0.01-0.04] and Spanish: OR, 0.04 [95% CI, 0.02-0.06] vs English) and hospital teaching status (nonteaching: OR, 0.43 [95% CI, 0.32-0.56] vs teaching). CONCLUSIONS: Linguistic disparities exist in access to cancer care for non-English-speaking patients, emphasizing the need for focused interventions to mitigate systems-level communication barriers.

Real-World Use of Systemic Therapies for the Treatment of Advanced Thyroid Cancers.

OBJECTIVE: In the last decade, new systemic treatment options have been made available for patients with advanced thyroid cancer. However, little is known about the real-world utilization of these systemic therapies. METHODS: We used Optum's de-identified Clinformatics® Data Mart Database to characterize trends in the use of 15 systemic therapies that are available for the treatment of advanced thyroid cancer between 2013 and 2021. Joinpoint regression was used to calculate annual percentage changes in the use of systemic therapy by patients' race/ethnicity. The sequence of therapies was determined by the date of prescription claims. RESULTS: Between 2013 and 2021, the annual number of patients treated for advanced thyroid cancer with systemic therapy increased from 45 patients in 2013 to 114 patients in 2021 (N of total cohort = 885). Most patients were female (54.7%) and non-Hispanic White (62.1%). Between 2013 and 2021, there was a significant decrease in the proportion of non-Hispanic White patients treated for advanced thyroid cancer with systemic therapy (annual percentage change -3.9%, 95% confidence intervals, -6.0% to -1.8%). Since its approval by the US Food and Drug Administration (FDA) in 2015, lenvatinib remains the most frequently prescribed first-line therapy for the treatment of radioiodine-refractory thyroid cancer (48.8% of patients between 2017 and 2021). Between 2017 and 2021, most patients (79.7%) were initiated on 1 of the 10 FDA-approved agents and 81.7% received only a first-line therapy. CONCLUSIONS: Between 2013 and 2021, the use of systemic treatment options for advanced thyroid cancer increased significantly, largely driven by the prescription of lenvatinib following its approval by the FDA in 2015, with an increasing trend for use in non-White patients.

Performance of Afirma genomic sequencing classifier and histopathological outcome in Bethesda category III thyroid nodules: Initial versus repeat fine-needle aspiration.

BACKGROUND: There is limited data comparing the performance of Afirma Genomic Sequencing Classifier (GSC) in thyroid nodules carrying an initial versus a repeat diagnosis of atypia of undetermined significance (AUS). This study reported an institutional experience in this regard. MATERIALS AND METHODS: This retrospective study included consecutive thyroid nodules that had an initial or a repeat AUS diagnosis and had a subsequent GSC diagnostic result (benign or suspicious) from 2017 to 2021. All nodules were followed by surgical intervention or by clinical and/or ultrasound monitoring. GSC's benign call rate (BCR), rate of histology-proven malignancy associated with a suspicious GSC result, and diagnostic parameters of GSC were calculated and compared between the two cohorts (initial versus repeat AUS). Statistical significance was defined with a p-value of <.05 for all analysis. RESULTS: A total of 202 cases fulfilled inclusion criteria, including 67 and 135 thyroid nodules with an initial and a repeat AUS diagnosis, respectively. BCR was 67% and 66% in initial and repeat AUS cohorts, respectively. Rate of histology-proven malignancy associated with a suspicious GSC result were 22% and 24% in initial and repeat AUS cohorts, respectively. Compared with the repeat AUS cohort, the initial AUS cohort showed slightly lower sensitivity (83% vs. 100%), specificity (70% vs. 73%), PPV (23% vs. 24%), NPV (98% vs. 100%), and diagnostic accuracy (72% vs. 75%). Nevertheless, these differences did not reach statistical significance. CONCLUSION: GSC demonstrated comparable performance in thyroid nodules with a repeat AUS diagnosis versus nodules with an initial AUS diagnosis.

The psychosocial impact of thyroid cancer.

PURPOSE OF REVIEW: This review discusses the psychosocial impact of thyroid cancer diagnosis and management. It summarizes recent findings, presents management options, and briefly discusses future directions. RECENT FINDINGS: A thyroid cancer diagnosis and its downstream management can impact patients in a variety of ways, including contributing to distress, worry, worse quality of life, and in some cases, anxiety and depression. Racial/ethnic minorities, those with lower education, women, adolescents/young adults, and individuals with a prior mental health conditions are a few of the patient groups at greater risks for adverse psychosocial effects from their thyroid cancer diagnosis and management. Findings are mixed, but some studies suggest treatment, for example, more intensive treatment as opposed to less, may be associated with a greater psychosocial impact. Clinicians providing care to thyroid cancer patients use a variety of resources and techniques, some more effective than others, to provide support. SUMMARY: A thyroid cancer diagnosis and its subsequent treatment can greatly impact a patient's psychosocial wellbeing, particularly for at-risk groups. Clinicians can help their patients by informing them of the risks associated with treatments and by offering education and resources for psychosocial support.

Access Denied: Disparities in Thyroid Cancer Clinical Trials.

For thyroid cancer clinical trials, the inclusion of participants from diverse patient populations is uniquely important given existing racial/ethnic disparities in thyroid cancer care. Since 2011, a paradigm shift has occurred in the treatment of advanced thyroid cancer with the approval of multiple systemic therapies by the US Food and Drug Administration based on their use in the clinical trials setting. Although these clinical trials recruited patients from up to 164 sites in 25 countries, the inclusion of racial/ethnic minority patients remained low. In this mini-review, we provide an overview of barriers to accessing cancer clinical trials, framed in the context of why patients with thyroid cancer may be uniquely vulnerable. Multilevel interventions and increased funding for thyroid cancer research are necessary to increase access to and recruitment of under-represented patient populations into thyroid cancer clinical trials.

Physician-Reported Barriers to Osteoporosis Screening: A Nationwide Survey.

OBJECTIVE: Despite increased awareness, osteoporosis screening rates remain low. The objective of this survey study was to identify physician-reported barriers to osteoporosis screening. METHODS: We conducted a survey of 600 physician members of the Endocrine Society, American Academy of Family Practice, and American Geriatrics Society. The respondents were asked to rate barriers to osteoporosis screening in their patients. We performed multivariable logistic regression analyses to determine correlates with the most commonly reported barriers. RESULTS: Of 566 response-eligible physicians, 359 completed the survey (response rate, 63%). The most commonly reported barriers to osteoporosis screening included patient nonadherence (63%), physician concern about cost (56%), clinic visit time constraints (51%), low on the priority list (45%), and patient concern about cost (43%). Patient nonadherence as a barrier was correlated with physicians in academic tertiary centers (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.06-5.13), whereas clinic visit time constraints were correlated with physicians in both community-based academic affiliates and academic tertiary care ([OR, 1.96; 95% CI, 1.10-3.50] and [OR, 2.48; 95% CI, 1.22-5.07], respectively). Geriatricians (OR, 0.40; 95% CI, 0.21-0.76) and physicians with >10 years in practice were less likely to report clinic visit time constraints as a barrier (11-20 years: OR, 0.41; 95% CI, 0.20-0.85; >20 years: OR, 0.32; 95% CI, 0.16-0.65). Physicians with more patient-facing time (3-5 compared with 0.5-2 d/wk) were more likely to place screening low on the priority list (OR, 2.66; 95% CI, 1.34-5.29). CONCLUSION: Understanding barriers to osteoporosis screening is vital in developing strategies to improve osteoporosis care.

Thyroid cancer.

The past 5-10 years have brought in a new era in the care of patients with thyroid cancer, with the introduction of transformative diagnostic and management options. Several international ultrasound-based thyroid nodule risk stratification systems have been developed with the goal of reducing unnecessary biopsies. Less invasive alternatives to surgery for low-risk thyroid cancer, such as active surveillance and minimally invasive interventions, are being explored. New systemic therapies are now available for patients with advanced thyroid cancer. However, in the setting of these advances, disparities exist in the diagnosis and management of thyroid cancer. As new management options are becoming available for thyroid cancer, it is essential to support population-based studies and randomised clinical trials that will inform evidence-based clinical practice guidelines on the management of thyroid cancer, and to include diverse patient populations in research to better understand and subsequently address existing barriers to equitable thyroid cancer care.

Banking on Fertility Preservation: Financial Concern for Adolescent and Young Adult Cancer Patients Considering Oncofertility Services.

Purpose: Financial concern is a major issue for adolescent and young adult (AYA) cancer patients. Furthermore, unaddressed oncofertility challenges (e.g., infertility) are linked to psychological distress and decreased overall quality of life. Little is known about how financial concern in terms of oncofertility (i.e., concern regarding affording fertility preservation [FP] services) impacts AYAs' decision making and experiences. Methods: AYA cancer patients (n = 27) aged 12-25 years whose cancer treatment conferred risk of infertility were recruited through electronic health record query. Participants completed semi-structured interviews, which were recorded, transcribed, and deductively coded for themes related to information needs, knowledge of treatment effects on fertility, and reproductive concerns after cancer. Emergent, inductive themes related to financial concern were identified. The Institutional Review Board at the University of Michigan approved this study (HUM#00157267). Results: Financial concern was a dominant theme across the qualitative data. Emergent themes included (1) varied access to health insurance, (2) presence of parental/guardian support, (3) reliance upon financial aid, (4) negotiating infertility risk, and (5) lack of preparation for long-term costs. AYAs relied heavily upon parents for out-of-pocket and insurance coverage support. Some participants sought financial aid when guided by providers. Several participants indicated that no financial support existed for their circumstance. Conclusions: Financial consequences in terms of oncofertility are a major issue affecting AYA cancer patients. The incidence and gravity of financial concern surrounding affording oncofertility services merits attention in future research (measuring financial resources of AYAs' parental/support networks), clinical practice (strategically addressing short- and long-term costs; tailored psychosocial support), and health care policy (promoting legislation to mandate pre- and post-treatment FP coverage).

The relative importance of treatment outcomes to surgeons' recommendations for low-risk thyroid cancer.

BACKGROUND: The treatment of low-risk thyroid cancer is controversial. We evaluated the importance of treatment outcomes to surgeons' recommendations. METHODS: A cross-sectional survey asked thyroid surgeons for their treatment recommendations for a healthy 45-year-old patient with a solitary, low-risk, 2-cm papillary thyroid cancer. The importance of the 10 treatment outcomes (survival, recurrence, etc.) to their recommendation was evaluated using constant sum scaling, a method where 100 points are allocated among the treatment outcomes; more points indicate higher importance. The distribution of points was compared between surgeons recommending total thyroidectomy and surgeons recommending lobectomy using Hottelling's T2 test. RESULTS: Of 165 respondents (74.3% response rate), 35.8% (n = 59) recommended total thyroidectomy and 64.2% (n = 106) lobectomy. The importance of the 10 treatment outcomes was significantly different between groups (P < .05). Surgeons recommending total thyroidectomy were most influenced by the risk of recurrence (19.1 points; standard deviation 16.5) and rated this 1.6-times more important than those recommending lobectomy. Conversely, surgeons recommending lobectomy placed high emphasis on need for hormone replacement (14.3 points; standard deviation 15.4), rating this 3.1-times more important than those recommending total thyroidectomy. CONCLUSION: Surgeons who recommend total thyroidectomy and those who recommend lobectomy differently prioritize the importance of cancer recurrence and thyroid hormone replacement. Understanding how surgeons' beliefs influence their recommendations is important for ensuring patients receive treatment aligned with their values.

Variation in the Diagnosis of Noninvasive Follicular Thyroid Neoplasm with Papillary-like Nuclear Features.

CONTEXT: Noninvasive encapsulated follicular variant of papillary thyroid cancer was reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) in January 2017. The impact of this nomenclature change at a population level remains unknown. OBJECTIVE: Examine use of NIFTP across different US regions and populations. DESIGN: Descriptive epidemiology study using SEER-22 data (2000-2019). PARTICIPANTS: Individuals diagnosed with papillary or follicular thyroid cancer (2000-2019) or NIFTP (2017-2019). MAIN OUTCOME MEASURES: Annual incidence rates of thyroid cancer by subtype and NIFTP. Using 2018-2019 data, (1) rates of NIFTP at the 17 SEER-22 sites and (2) comparison of demographics for patients diagnosed with NIFTP vs papillary and follicular thyroid cancer. RESULTS: NIFTP comprised 2.2% and 2.6% of cases in 2018 and 2019, respectively. Between 2018 and 2019, large heterogeneity was observed in the regional use of NIFTP diagnosis, with site-specific incidence rates between 0.0% and 6.2% (median 2.8%, interquartile range 1.3-3.6%). A diagnosis of NIFTP (vs papillary and follicular thyroid cancer) in 2018 and 2019 was significantly associated with older age (P = 0.012 and P = 0.009, respectively), Black race (both Ps < 0.001), and non-Hispanic ethnicity (both Ps < 0.001). CONCLUSIONS: Marked variation exists in the use of the NIFTP diagnosis. The recent 2021 coding change that resulted in NIFTP, a tumor with uncertain malignant potential and for which there is no long-term outcome data available, no longer being a reportable diagnosis to SEER will disproportionately affect vulnerable patient groups such as older patients and Black patients, in addition to patients who reside in regions with higher rates of NIFTP diagnoses.

Thyroid Carcinoma, Version 2.2022, NCCN Clinical Practice Guidelines in Oncology.

Differentiated thyroid carcinomas is associated with an excellent prognosis. The treatment of choice for differentiated thyroid carcinoma is surgery, followed by radioactive iodine ablation (iodine-131) in select patients and thyroxine therapy in most patients. Surgery is also the main treatment for medullary thyroid carcinoma, and kinase inhibitors may be appropriate for select patients with recurrent or persistent disease that is not resectable. Anaplastic thyroid carcinoma is almost uniformly lethal, and iodine-131 imaging and radioactive iodine cannot be used. When systemic therapy is indicated, targeted therapy options are preferred. This article describes NCCN recommendations regarding management of medullary thyroid carcinoma and anaplastic thyroid carcinoma, and surgical management of differentiated thyroid carcinoma (papillary, follicular, Hürthle cell carcinoma).
