No improvement in survival of older women with cervical cancer-A nationwide study.

AIM: This study aims to report trends in primary treatment and survival in cervical cancer (CC) to identify opportunities to improve clinical practice and disease outcome. METHODS: Patients diagnosed with CC between 1989 and 2018 were identified from the Netherlands Cancer Registry (N = 21,644). Trends in primary treatment and 5-year relative survival were analysed with the Cochran-Armitage trend test and multivariable Poisson regression, respectively. RESULTS: In early CC, surgery remains the preferred treatment for ages 15-74. Overall, it was applied more often in younger than in older patients (92% in 15-44; 64% in 65-74). For 75+, surgery use was stable over time (38%-41%, p=0.368), while administration of radiotherapy decreased (57%-29%, p < 0.001). In locally advanced CC, chemoradiation use increased over time (5%-65%, p < 0.001). It was applied least often for 75+, in which radiotherapy remains most common (54% in 2014-2018). In metastatic CC, chemotherapy use increased over time (11%-28%, p < 0.001), but varied across age groups (6%-40% in 2014-2018). In patients treated with primary chemoradiation, regardless of stage, brachytherapy use increased over time (p ≤ 0.001). Full cohort 5-year survival increased from 68% to 74% (relative excess risk 0.55; 95% confidence interval [0.50-0.62]). Increases were most significant in locally advanced CC (38%-60%; 0.55 [0.47-0.65]). Survival remained stable in 75+ (38%-34%; 0.82 [0.66-1.02]). CONCLUSION: Relative survival for cervical cancer increased over the last three decades. The proportion of older patients receiving preferred treatment lags behind. Consequently, survival did not improve in the oldest patients.

Trends in Financial Relationships Between Industry and Radiation Oncologists Versus Other Physicians in the United States from 2014 to 2018.

PURPOSE: The Open Payments transparency program publishes data on industry-physician payments, in part to discourage relationships considered inappropriate including gifts, meals, and speaker's bureau fees. We evaluated trends in physician-level payments to test whether implementation of Open Payments resulted in fewer industry-radiation oncologist (RO) interactions or shifted interactions toward those considered more appropriate compared with medical oncologists (MOs) and other hospital-based physicians (HBPs). METHODS AND MATERIALS: We performed a retrospective, population-based cohort study of practicing US ROs versus MOs and HBPs in 2014 matched to general (nonresearch) payments between 2014 and 2018. Trends in payments were analyzed and reported by nature of payment. Values of payments to ROs from the top 10 companies were identified. RESULTS: From 2014 to 2018, 3379 (90.3%) ROs accepted 106,930 payments totaling $40.8 million. The per-physician number and value of payments was lower in radiation oncology than in medical oncology and higher than HBPs. The proportion of ROs accepting payments increased from 61.8% in 2014 to 64.2% in 2018; the proportion of MOs accepting payments decreased from 78.7% to 77.7%; and the proportion of HBPs decreased from 40.8% to 37.5%, respectively. The annual per-physician value and number of payments accepted by ROs and MOs increased. Payments in entertainment, meals, travel and lodging, and gifts increased among ROs and remained stable or decreased among MOs and HBPs. Consulting payments increased across all groups. Top RO payors produced novel cancer therapeutics, hydrogel spacers, radiation treatment machines, and opioids. CONCLUSIONS: Industry payments to ROs have become more common since OP's inception, while becoming less common for MOs and HBPs. Payments to ROs and MOs have become more frequent and of modestly increasing value compared with other HBPs, for whom the value is decreasing. No large changes in the nature of relationships were seen in ROs. Increased engagement with financial conflicts of interest is needed in radiation oncology.

Changes in Population-Level and Institutional-Level Prescribing Habits of Radioiodine Therapy for Papillary Thyroid Cancer.

Background: In the past two decades, new evidence and guidelines have emerged to refine recommendations for the use of radioactive iodine (RAI) therapy after thyroidectomy for cancer. We aim to describe national trends in RAI utilization, assess the impact of individual hospitals on RAI utilization, and examine whether variation in prescribing habits has declined over time. Methods: The National Cancer Database (NCDB) was queried from 2004 to 2016 for patients with papillary thyroid cancer (PTC) who received total thyroidectomy. Trends were analyzed using Joinpoint analysis. Hospital-specific effects and variation in prescribing habits were assessed through a hierarchical, mixed regression model. Results: RAI utilization declined from 61.0% in 2004 to 43.9% in 2016. RAI use declined most profoundly in patients with T1a, N0/X, M0 PTC without extrathyroidal extension (34.8% in 2004 to 9.5% in 2015), but continues to be used commonly in patients with advanced disease for whom it is routinely recommended (73.4% in 2004 to 72.0% in 2015). Furthermore, ∼80% of hospitals in 2016 utilized at or below the median utilization rate in 2006. Variation in RAI utilization across hospitals decreased by ∼50% from 2004 to 2016 (Levene's test p < 0.001), with a significant decline (p = 0.002) in the variation after 2012 (confidence interval: 2010 to 2014). Conclusions: Recommendations for whom to prescribe RAI appear to have impacted both the number of patients receiving RAI and the variation in prescribing habits across hospitals. Hospital selection has contributed less to the probability of receiving RAI over time.

I Can't Breathe: The Continued Disproportionate Exclusion of Black Physicians in the United States Radiation Oncology Workforce.

PURPOSE: Black physicians remain disproportionately underrepresented in certain medical specialties, yet comprehensive assessments in radiation oncology (RO) are lacking. Our purpose was to report current and historical representation trends for Black physicians in the US RO workforce. METHODS AND MATERIALS: Public registries were used to assess significant differences in 2016 representation for US vs RO Black academic full-time faculty, residents, and applicants. Historical changes from 1970 to 2016 were reported descriptively. Linear regression was used to assess significant changes for Black residents and faculty from 1995 to 2016. RESULTS: In 2016, Black people represented 3.2% vs 1.5% (P < .001), 5.6% vs 3.2% (P = .005), and 6.5% vs 5.4% (P = .352) of US vs RO faculty, residents, and applicants, respectively. Although RO residents nearly doubled from 374 (1974) to 720 (2016), Black residents peaked at 31 in 1984 (5.9%; 31 of 522) and fell to 23 (3.2%; 23 of 720) in 2016 across 91 accredited programs; Black US graduate medical education trainees nearly doubled over the same period: 3506 (1984) to 6905 (2016). From 1995 to 2016, Black US resident representation significantly increased by 0.03%/y, but decreased significantly in RO by -0.20%/y before 2006 and did not change significantly thereafter. Over the same period, Black US faculty representation significantly increased by 0.02%/y, whereas Black RO faculty significantly increased by 0.07%/y before 2006, then decreased significantly by -0.16%/y thereafter. The number of Black RO faculty peaked at 37 in 2006 (3.1%; 37 of 1203) and was 27 (1.5%; 27 of 1769) in 2016, despite the nearly 1.5-fold increase in the number of both RO faculty and Black US faculty overall (4169 in 2006 and 6047 in 2016) during that period. CONCLUSIONS: Black physicians remain disproportionately underrepresented in RO despite an increasing available pipeline in the US physician workforce. Deliberate efforts to understand barriers to specialty training and inclusion, along with evidence-based targeted interventions to overcome them, are needed to ensure diversification of the RO physician workforce.

National Trends and Dynamic Responses in the Canadian Radiation Oncology Workforce From 1990 to 2018.

PURPOSE: To report radiation oncology (RO) workforce and cancer incidence trends in Canada and explore the relationship between the two. METHODS AND MATERIALS: Canadian radiation oncologist, trainee, and cancer incidence data from 1990 to 2018 were collected from the following publicly accessible administrative and health information databases: Canadian Post-MD Education Registry (1990-2018), Canadian Medical Association Physician Data Centre (1994-2018), Canadian Institute for Health Information/Scott's Medical Database (1990-2017), Canadian Cancer Registry (1990-2017), and Statistics Canada (1990-2017). Descriptive statistics were used to summarize the data. RESULTS: The Canadian RO workforce grew from 240 radiation oncologists in 1990 to 567 in 2018, with the largest growth period from 2005 to 2015 adding 207 radiation oncologists. Regional analyses revealed steady or stepwise growth in all Canadian regions, except in Québec, where the number of radiation oncologists decreased from 86 in 1990 to 57 in 2003 before rising to 139 by 2018. Trainee totals were between 54 and 173 per year with 2 periods of growth (1990-1996 and 2001-2008) and regression (1996-2001 and 2008-2018), signifying trainee supply variability. Female proportions of the workforce and trainees, respectively, rose steadily from 18% to 38% and 28% to 50%, while the workforce proportion with non-Canadian medical degrees decreased from 40% to 26%. Radiation oncologists younger than 40 years increased from 70 to 171, whereas those age 60 years and older decreased from 85 in 1990 to 31 in 2002 and then increased to 108 in 2017. Annual cancer incidence rose steadily from 103,780 to 206,290 cases/year. The annual cancer incidence-to-provider ratio fluctuated (364-475:1) and trended lower with time, and proportional cancer incidence-to-provider ratios varied between 0.7:1 and 1.6:1 in Canada's regions before approaching 1:1. CONCLUSIONS: Our study demonstrates the challenges and successes of managing the Canadian radiation oncologist workforce. These data will inform policy makers and other stakeholders to ensure that the profession meets the current and future needs of Canadian cancer patients.

High-volume providers and brachytherapy practice: A Medicare provider utilization and payment analysis.

PURPOSE: Brachytherapy is an important component of the treatment of gynecologic and prostate cancers, with data supporting its impact on clinical outcomes. Prior data have suggested that brachytherapy tends to be focused at high-volume centers. Medicare reimbursement data can provide an understanding of the distribution of brachytherapy cases among billing providers. The objective of this study is to quantify the distribution of brachytherapy cases and high volume providers. METHODS AND MATERIALS: The Medicare Physician and Other Supplier Public Use File was queried for individual physicians who had performed brachytherapy for more than 10 patients with gynecologic or prostate cancer in the years 2012-2015. Aggregate data were also queried. Trends were identified, and basic summary statistics were tabulated. RESULTS: During the study period, there was an increase in vaginal brachytherapy (3328 unique cases in 2012-4308 in 2015) but a decrease in intrauterine implants, such as tandem placements (1522 in 2012-1307 in 2015) and prostate brachytherapy (8860 in 2012-6527 in 2015). High-volume providers treating more than 10 patients represented a disproportionate number of patients treated, particularly with intra-uterine brachytherapy, representing no more than 1.2% of the active providers in a given year but up to 11.1% of intra-uterine brachytherapy cases. CONCLUSIONS: Among Medicare claims, a small number of providers accounted for a significant proportion of gynecologic and prostate brachytherapy cases, particularly in the case of intrauterine implants. The vast majority of brachytherapy providers perform limited cases in this population. Efforts toward improving access to intrauterine implants in Medicare patients should be a national priority.

Geriatric Assessment for Older Patients with Non-small Cell Lung Cancer: Daily Practice of Centers Participating in the NVALT25-ELDAPT Trial.

INTRODUCTION: Geriatric assessment (GA) for older patients with lung cancer could provide insight into vulnerability, cognitive impairment, and risk of toxicity. Discontinuation and complications of intensive treatment could potentially be prevented in vulnerable and frail patients. This study aimed to evaluate current clinical practice of GA for older patients with lung cancer in the Netherlands and identify potential hurdles for implementation. METHODS: Pulmonologists and radiation oncologists participating in the NVALT25-ELDAPT trial completed an online questionnaire regarding current practice of GA, added value of GA for treatment decision-making and logistic barriers for patients with non-small cell lung cancer. RESULTS: 15 out of 17 centers responded. Three performed GA as standard procedure, three on indication, eight considered a frailty screening step before GA, and one did not perform GA. Suspicion of cognitive problems was mentioned most often as indication for GA and of added value for treatment decision-making, followed by older age, curative-intent treatment, and stage I-III lung cancer. Administered instruments for screening and extensive GA were diverse. Main barriers to implement GA in clinical practice were logistic problems (timescales and availability of trained personnel). CONCLUSION: The use of GA in clinical practice for patients with lung cancer varied widely across centers regarding instruments and domains. Physicians are uniform in their opinion about indications for GA and the added value for treatment decision-making. Research should focus on manageable instruments and important domains to assess for this heterogeneous group of older patients with lung cancer to optimize treatment selection. Trial registration The NVALT25-ELDAPT trial is registered under trial number NCT02284308. Details are available at http://www.eldapt.org (predominantly in Dutch).

Impact of CALGB 9343 Trial and Sociodemographic Variation on Patterns of Adjuvant Radiation Therapy Practice for Elderly Women (≥70 Years) with Stage I, Estrogen Receptor-positive Breast Cancer: Analysis of the National Cancer Data Base.

BACKGROUND: The Cancer and Leukemia Group B (CALGB) 9343 trial demonstrated that adjuvant radiation therapy (RT) can be omitted in women 70 years or older, with small (≤2 cm), negative lymph nodes, estrogen receptor (ER)-positive breast cancer. We examined whether RT usage following the CALGB publication had decreased over time and evaluated sociodemographic and clinical factors associated with RT omission. MATERIALS AND METHODS: From the National Cancer Data Base, we analyzed a cohort of 120,308 women aged 70 years or older with stage I, ER-positive breast cancer who underwent lumpectomy. Patients were classified into two groups based on the time of CALGB 9343 publication: (i) pre-CALGB (up to 2004), and (ii) post-CALGB (2005-2012). Clinicopathological and sociodemographic variables were compared between pre- and post-CALGB groups. Chi-square and multivariable logistic regression were employed, with the omission of adjuvant RT as the primary outcome in the regression analysis. RESULTS: Radiation therapy usage decreased by 4.1% after CALGB publication (on average 71.6% pre-CALGB vs. 67.5% post-CALGB; p<0.0001). Almost one-third of women aged ≥85 years received RT in the post-CALGB group. In a multivariable model, the variables significantly associated with increased odds for omission of RT in the post-CALGB group were: advanced age, African-American, increased great circle distance, therapy under academic research program, residents of East South-Central region, living in a rural population <2,500 not adjacent to a metropolitan area, low income level, Medicaid recipients, high comorbidity index, small tumor, well-differentiated histology, residual tumor, and lack of receipt of chemotherapy and anti-hormonal therapy. CONCLUSION: During the study period, the CALGB trial publication had a minimal impact on the rate of adjuvant RT use among elderly women with small, ER-positive breast cancers. Significant variation in RT usage existed across sociodemographic strata.

Variation in Practice Patterns of Korean Radiation Oncologists for Spine Metastasis between 2009 and 2014.

PURPOSE: The Korean Society of Radiation Oncologists (KOSRO) conducted the Patterns of Care Study (PCS) of radiotherapy (RT) for spine metastases in 2009. The current study was conducted to investigate current practice patterns and compare them with the results of the PCS. MATERIALS AND METHODS: The survey questionnaire was composed of 10 questions regarding general information and seven questions for each of two clinical scenarios. RESULTS: Fifty-four members of the KOSRO answered at least one question on the web-based questionnaire. The yearly number of patients treated who underwent palliative spine RT was greater than 200 in 14 (25.9%), 51 to 100 in 13 (24.1%), and 31 to 50 in 11 respondents (20.4%). Scenario 1 described a patient presenting with cord compressive spine metastasis in multiple bones and liver metastasis from non-small cell lung cancer. Thirty gray (Gy) in 10 fractions was chosen by 35 respondents (64.8%). Scenario 2 described a case of a single spine metastasis without progression after targeted therapy. Thirty Gy in 10 fractions was chosen by 19 respondents (35.2%), and a single fraction or less than four fractions of stereotactic ablative radiotherapy (SABR) were selected by 18 respondents (33.3%). When compared with the 2009 PCS, practice patterns of Korean radiation oncologists had not changed significantly over 5 years, except that SABR emerged as a new treatment modality in the selected population. CONCLUSION: The 2014 PCS demonstrated that multiple fraction RT is still preferred in a considerable proportion of Korean radiation oncologists.
