The case for radiotherapy in a Value based environment

AimDescribe the Value proposition for radiotherapy (RT) in the United States.BackgroundIn the United States since 2005, two forces have worked to decrease RT cost per patient: Federal changes in reimbursement and hypofractionation of treatment courses. We theorize that these have driven stable reimbursement in the context of increasing technology of intensity modulation (IMRT) and image guidance (IGRT). This phenomenon provides increasing Value of the discipline to patients and systems.Materials and methodsWe searched the Medicare Physician/Supplier data for Program Payments per Person with Utilization for 2000 through 2016. This involves two databases: Enrollment Database (EDB) for 2000–2012 and Common Medicare Enrollment (CME) since 2013. RT payments to individual patients accessing services were retrieved.ResultsTaking into account the change of calculation algorithm used by CMS in 2013, costs per patient were similar in 2012 and 2003, and 2016 and 2013.ConclusionsIn the United States, stabilizing costs in the face of increasing work, better outcomes, and decreased toxicity contributes to increasing RT value over the past 10 years.     

MicroRNAs that affect prostate cancer: emphasis on prostate cancer in African Americans

Abstract

Although concerted efforts have been directed toward eradicating health disparities in the United States, the disease and mortality rates for African American men still are among the highest in the world. We focus here on the role of microRNAs (miRNAs) in the signaling pathways of androgen receptors and growth factors that promote the progression of prostate cancer to more aggressive disease. We explore also how differential expression of miRNAs contributes to aggressive prostate cancer including that of African Americans.     

Role of Endocrinologists In Eliminating Health Care Disparities

ObjectiveTo review some of the persistent disparities in health and health care in the United States related to race, ethnicity, and socioeconomic status, with a focus on diabetes mellitus and obesity, and to discuss the role of endocrinologists in preventing these disparities.MethodsSome of the efforts made by the US government, such as public health strategies, to address health disparities are outlined, and statistics about diabetes and obesity are presented.ResultsThe elimination of health disparities, recognized as a national challenge for decades, is a national priority as defined in the national goals for Healthy People 2010. Health disparities refer to the differences in the quality of health and health care access and outcomes across racial, ethnic, and socioeconomic groups. Such disparities may be related to the patient (education, socioeconomic status, environment, language), the health care system (location, structural barriers, financial resources), or the provider, including a lack of diversity in the health care workforce. Endocrinologists are responsible for the care of many patients with chronic diseases, including obesity and diabetes mellitus. Both of these chronic diseases are diagnosed with increased frequency in minority populations and are preventable, difficult to manage, and associated with many complications and high health care costs.ConclusionThe role of endocrinologists is to provide equitable, affordable, accessible, high-quality, timely, cost-effective, and culturally sensitive health care. They must be involved in population health decisions and development of optimal health care policy so that endocrine disorders can ultimately be prevented. In addition, they must educate themselves, their patients, and the community regarding maintenance of healthy lifestyles to prevent complications. (Endocr Pract. 2009;15:612-623)     

Impact of hospital volume on mortality for brain metastases treated with radiation

BackgroundThe impact of hospital volume on cancer patient survival has been demonstrated in the surgical literature, but sparsely for patients receiving radiation therapy (RT). This analysis addresses the impact of hospital volume on patients receiving RT for the most common central nervous system tumor: brain metastases.Materials and methodsAnalysis was conducted using the National Cancer Database (NCDB) from 2010–2015 for patients with metastatic brain disease from lung cancer, breast cancer, and colorectal cancer requiring RT. Hospital volume was stratified as high-volume (≥ 12 brain RT/year), moderate (5–11 RT/year), and low (< 5 RT/year). The effect of hospital volume on overall survival was assessed using a multivariable Cox regression model.ResultsA total of 18,841 patients [9479 (50.3%) men, 9362 (49.7%) women; median age 64 years] met the inclusion criteria. 16.7% were treated at high-volume hospitals, 36.5% at moderate-volume, and the remaining 46.8% at low-volume centers. Multivariable analysis revealed that mortality was significantly improved in high-volume centers (HR: 0.95, p = 0.039) compared with low-volume centers after accounting for multiple demographics including age, sex, race, insurance status, income, facility type, Charlson-Deyo score and receipt of palliative care.ConclusionHospitals performing 12 or more brain RT procedures per year have significantly improved survival in brain metastases patients receiving radiation as compared to lower volume hospitals. This finding, independent of additional demographics, indicates that the increased experience associated with increased volume may improve survival in this patient population.     

County-level characteristics associated with incidence,late-stage incidence,and mortality from screenable cancers

BackgroundCancer screening differs by rurality and racial residential segregation, but the relationship between these county-level characteristics is understudied. Understanding this relationship and its implications for cancer outcomes could inform interventions to decrease cancer disparities.MethodsWe linked county-level information from national data sources: 2008–2012 cancer incidence, late-stage incidence, and mortality rates (for breast, cervical, and colorectal cancer) from U.S. Cancer Statistics and the National Death Index; metropolitan status from U.S. Department of Agriculture; residential segregation derived from American Community Survey; and prevalence of cancer screening from National Cancer Institute’s Small Area Estimates. We used multivariable, sparse Poisson generalized linear mixed models to assess cancer incidence, late-stage incidence, and mortality rates by county-level characteristics, controlling for density of physicians and median household income.ResultsCancer incidence, late-stage incidence, and mortality rates were 6–18% lower in metropolitan counties for breast and colorectal cancer, and 2–4% lower in more segregated counties for breast and colorectal cancer. Generally, reductions in cancer associated with residential segregation were limited to non-metropolitan counties. Cancer incidence, late-stage incidence, and mortality rates were associated with screening, with rates for corresponding cancers that were 2–9% higher in areas with more breast and colorectal screening, but 2–15% lower in areas with more cervical screening.DiscussionLower cancer burden was observed in counties that were metropolitan and more segregated. Effect modification was observed by metropolitan status and county-level residential segregation, indicating that residential segregation may impact healthcare access differently in different county types. Additional studies are needed to inform interventions to reduce county-level disparities in cancer incidence, late-stage incidence, and mortality.     

Primary squamous cell carcinoma of the breast: A rare case report

BackgroundSquamous cells are normally not found inside the breast. Therefore, a primary squamous cell carcinoma of the breast is an exceptional phenomenon and the management of this type of disease is still debated.AimClinical outcome assessment of a patient with squamous cell carcinoma of the breast.Materials and methodsWe report a case of primary squamous cell carcinoma of the breast (T1cN0M0) in a 51-years-old woman who underwent breast conserving surgery plus adjuvant chemotherapy and radiation therapy (RT).ResultsWith a follow up of 43 months, the patient is alive with no evidence of local or distant recurrence. The patient had Grade 2 acute skin toxicity. No late skin or respiratory toxicity was observed.ConclusionsPure primary squamous cell carcinoma of the breast is a rare and aggressive disease, often treatment-refractory. Our case shows that the addition of RT after breast conserving surgery, allows to achieve a high local control without adding severe toxicity. A multidisciplinary approach seems to be the optimal management for early stages in this rare disease.     

The national utilization of immediate and early delayed breast reconstruction and the effect of sociodemographic factors

The purpose of this study was to identify important sociodemographic factors affecting the utilization of immediate and early delayed postmastectomy breast reconstruction in the United States. Using the Surveillance, Epidemiology, and End Results (SEER) program, all cases of mastectomy-treated breast cancer that were reported to a SEER registry in 1998 were identified. Data were limited to reconstructions within the first 4 months postmastectomy, and logistic regression was used to analyze the effects of sociodemographic variables on reconstruction rates. Of the 10,406 mastectomy-treated breast cancer patients, 1607 (15 percent) underwent reconstruction within the first 4 months postmastectomy. Compared with women 45 to 54 years old, those 35 to 44 years old were significantly more likely to have breast reconstruction (OR = 1.52, p < 0.001), but women 55 to 64, 65 to 74, and 75 years and older were significantly less likely to have reconstruction (OR = 0.42, p < 0.001; OR = 0.16, p < 0.001; OR = 0.04, p < 0.001, respectively). Compared with Caucasian women, African American, Hispanic, and Asian women were significantly less likely to have reconstruction (OR = 0.48, p < 0.001; OR = 0.45, p < 0.001; OR = 0.29, p < 0.001, respectively). In addition, a four-fold difference in reconstruction rates existed in high-use versus low-use regions. With regard to the type of reconstruction, patients younger than 35 and 65 to 74 years old were significantly less likely to receive autogenous tissue reconstruction compared with women 45 to 54 years old (OR = 0.47, p = 0.047; OR p = 0.61, p = 0.031, respectively). However, African Americans were significantly more likely to receive autogenous tissue reconstructions compared with Caucasians (OR = 2.03, p = 0.021). According to these data, the utilization of immediate and early delayed breast reconstruction in the United States is low and is significantly influenced by patients' age, race, and geographic location. Further research is needed to evaluate the impact of provider bias, patient preference, and barriers to care on the utilization of breast reconstruction in the United States.     

Racial disparity in breast cancer: can it be mattered for prognosis and therapy

Breast cancer (BC) has emerged as a deadly disease that affects the lives of millions of women worldwide. It is the second leading cause of cancer-related deaths in the United States. Advancements in BC screening, preventive measures and treatment have resulted in significant decline in BC related deaths. However, unacceptable levels of racial disparity have been consistently reported, especially in African-American (AA) women compared to European American (EA). AA women go through worse prognosis, shorter survival time and higher mortality rates, despite higher cancer incidence reported in EA. These disparities are independent of socioeconomic status, access to healthcare or age, or even the stage of BC. Recent race-specific genetic and epigenetic studies have reported biological causes, which form the crux of this review. However, the developments are just the tip of the iceberg. Prioritizing primary research towards studying race-specific tumor microenvironment and biological composition of the host system in delineating the cause of these disparities is utmost necessary to ameliorate the disparity and design appropriate diagnosis/treatment regimen for AA women suffering from BC. In this review article, we discuss emerging trends and exciting discoveries that reveal how genetic/epigenetic circuitry contributed to racial disparity and discussed the strategies that may help in future therapeutic development.     

Potential impact of the Affordable Care Act's preventive services provision on breast cancer stage: A preliminary assessment

IntroductionThe Affordable Care Act's (ACA) preventive services provision (PSP) removes copayments for preventive services such as cancer screening. We examined: 1) whether a shift in breast cancer stage occurred, and 2) the impact of the provision on racial/ethnic disparities in stage.Materials and methodsData from the National Cancer Database were used. The pre- and post-PSP periods were identified as 2007–2009 and 2011–2013, respectively. Proportion differences (PDs) and 95% confidence Intervals (CIs) were calculated.ResultsAll three racial/ethnic groups experienced a statistically significant shift toward Stage I breast cancer. Pre-PSP, the black:white disparity in Stage I cancer was −9.5 (95% CI: −8.9, −10.4) and the Latina:white disparity was −5.2 (95% CI: −4.0, −6.1). Post-PSP, the disparities improved slightly.DiscussionPreliminary data suggest that the ACA's PSP may have a meaningful impact on cancer stage overall and by race/ethnicity. However, more time may be needed to see reductions in disparities.     

Hypo- vs. normofractionated radiation therapy in breast cancer: A patterns of care analysis in German speaking countries

Aim and backgroundTo assess the use of hypofractionated (HG-RT) versus normofractionated radiation therapy (NF-RT) in Breast Cancer in German speaking countries.Materials and methodsBetween July 2017 and August 2017, an email-based survey was sent to all 1408 physicians that are members of the German Society of Radiation Oncology (DEGRO). The survey was completed by 180 physicians including 10 private practice owners and 52 heads of departments. The majority (82.1%) of the participants had >15 years of experience in radiation therapy (RT).ResultsThe majority (83.9%) of the heads of the departments agreed on using the normofractionated regimen of RT as standard treatment for breast cancer. Several physicians were skeptical about HF-RT with 6.5% of the heads refusing to use HF-RT. 40.3% of the departments had not seen the new German guidelines suggesting HF-RT as the standard treatment for all patients as positive or merely adopted a neutral position toward the guidelines (33.9%). The main points of criticism were increased side effects, an impaired toxicity profile and insufficient data. Most departments (46.8%) that perform HF-RT do so in an individual based manner.ConclusionsHF-RT remains controversial in German speaking countries. Our data shows that NF-RT remains the predominant method of treatment. HF-RT is only used in a defined group of patients as most German physicians agree that particular patients, especially those at higher risk of RT late effects, may benefit from a less intense, extended fractionation schedule.     

Radiation therapy for bone-only metastases in breast cancer patients: A GOCO survey of current clinical practice

IntroductionThe role of radiation therapy (RT) for patients with bone-only metastatic (BOM) breast cancer has not been investigated sufficiently. The aim of this survey was to evaluate current clinical practice in treating breast cancer patients with BOM in Radiation Therapy Departments in Catalonia and Occitania within the scope of the GOCO group.Materials and methodsAn electronic questionnaire was completed by experienced radiation oncologists from fourteen RT centers. The items surveyed the professional experience, therapeutic approach, technique, dose stereotactic body RT (SBRT) availability.ResultsAll Radiation Oncology Departments (ROD) in Catalonia (12) and Occitania (2) responded to the survey. Eleven (78.5%) of the RODs advise RT for BOM as initial treatment in the oligometastatic setting. RT to asymptomatic bone oligometastases is more often restricted for “risky lesions”. The most inconsistent approaches were the treatment for asymptomatic lesions, when to treat bone metastases with respect to systemic treatment (ST) and the indication for RT after a complete response to ST.ConclusionWhile BOM breast cancer patients have a relatively good prognosis, there is a lack of consistency in their approach with RT. This can be explained by the absence of evidence-based guidelines and an incomplete availability of SBRT.     

Evidence based radiation oncology with existing technology

Aim

To assess the real contribution of modern radiation therapy (RT) technology in the more common tumoral types in Central America, Caribbean and South America.

Background

RT is an essential tool in the management of cancer. RT can be either palliative or of curative intent. In general, for palliative radiotherapy, major technologies are not needed.

Materials and methods

We analyzed the contribution of RT technology based on published evidence for breast, lung, gastric, gallbladder, colorectal, prostate and cervix cancer in terms of disease control, survival or toxicity with especial focus on Latin America.

Results

Findings indicate that three dimensional conformal radiation therapy (3D RT) is the gold standard in most common type of cancer in the studied regions. Prostate cancer is probably the pathology that has more benefits when using new RT technology such as intensity modulated radiation therapy (IMRT) versus 3DRT in terms of toxicity and biochemical progression-free survival.

Conclusions

In light of the changes in technology, the ever-increasing access of developing countries to such technology, and its current coverage in Latin America, any efforts in this area should be aimed at improving the quality of the radiotherapy departments and centers that are already in place.     

Racial and socio-economic disparities in breast cancer hospitalization outcomes by insurance status

BackgroundBreast cancer remains a major cause of morbidity and mortality among women in the US, and despite numerous studies documenting racial disparities in outcomes, the survival difference between Black and White women diagnosed with breast cancer continues to widen. Few studies have assessed whether observed racial disparities in outcomes vary by insurance type e.g. Medicare/Medicaid versus private insurance. Differences in coverage, availability of networked physicians, or cost-sharing policies may influence choice of treatment and treatment outcomes, even after patients have been hospitalized, effects of which may be differential by race.PurposeThe aim of this analysis was to examine hospitalization outcomes among patients with a primary diagnosis of breast cancer and assess whether differences in outcome exist by insurance status after adjusting for age, race/ethnicity and socio-economic status.MethodsWe obtained data on over 67,000 breast cancer patients with a primary diagnosis of breast cancer for this cross-sectional study from the 2007–2011 Healthcare Cost and Utilization project Nationwide Inpatient Sample (HCUP-NIS), and examined breast cancer surgery type (mastectomy vs. breast conserving surgery or BCS), post-surgical complications and in-hospital mortality. Multivariable regression models were used to compute estimates, odds ratios and 95% confidence intervals.ResultsBlack patients were less likely to receive mastectomies compared with White women (OR: 0.80, 95% CI: 0.71–0.90), regardless of whether they had Medicare/Medicaid or Private insurance. Black patients were also more likely to experience post-surgical complications (OR: 1.41, 95% CI: 1.12–1.78) and higher in-hospital mortality (OR: 1.57, 95%: 1.21–2.03) compared with White patients, associations that were strongest among women with Private insurance. Women residing outside of large metropolitan areas were significantly more likely to receive mastectomies (OR: 1.89, 95% CI: 1.54–2.31) and experience higher in-hospital mortality (OR: 1.74, 95% CI: 1.40–2.16) compared with those in metropolitan areas, regardless of insurance type.ConclusionAmong hospitalized patients with breast cancer, racial differences in hospitalization outcomes existed and worse outcomes were observed among Black women with private insurance. Future studies are needed to determine factors associated with poor outcomes in this group of women, as well as to examine contributors to low BCS adoption in non-metropolitan areas.     

Reflecting on 20 years of breast cancer modeling in CISNET: Recommendations for future cancer systems modeling efforts

Since 2000, the National Cancer Institute’s Cancer Intervention and Surveillance Modeling Network (CISNET) modeling teams have developed and applied microsimulation and statistical models of breast cancer. Here, we illustrate the use of collaborative breast cancer multilevel systems modeling in CISNET to demonstrate the flexibility of systems modeling to address important clinical and policy-relevant questions. Challenges and opportunities of future systems modeling are also summarized. The 6 CISNET breast cancer models embody the key features of systems modeling by incorporating numerous data sources and reflecting tumor, person, and health system factors that change over time and interact to affect the burden of breast cancer. Multidisciplinary modeling teams have explored alternative representations of breast cancer to reveal insights into breast cancer natural history, including the role of overdiagnosis and race differences in tumor characteristics. The models have been used to compare strategies for improving the balance of benefits and harms of breast cancer screening based on personal risk factors, including age, breast density, polygenic risk, and history of Down syndrome or a history of childhood cancer. The models have also provided evidence to support the delivery of care by simulating outcomes following clinical decisions about breast cancer treatment and estimating the relative impact of screening and treatment on the United States population. The insights provided by the CISNET breast cancer multilevel modeling efforts have informed policy and clinical guidelines. The 20 years of CISNET modeling experience has highlighted opportunities and challenges to expanding the impact of systems modeling. Moving forward, CISNET research will continue to use systems modeling to address cancer control issues, including modeling structural inequities affecting racial disparities in the burden of breast cancer. Future work will also leverage the lessons from team science, expand resource sharing, and foster the careers of early stage modeling scientists to ensure the sustainability of these efforts.     

California's male suicide rate at record high.

Breast cancer is the most commonly occurring cancer in women and, until recently surpassed by lung cancer, was the leading cause of cancer-related death in women. It is the leading cause of death in women aged 39 to 44 years. The American Cancer Society has estimated that there will be 135,000 new cases of breast cancer and 42,300 breast cancer-related deaths in 1988. It is now predicted that breast cancer will develop in one out of every ten women in the United States. Given the clinical and public health significance of breast cancer, annual screening with mammography and clinical breast examination is recommended for women aged 50 and older to reduce breast cancer mortality.     

Impact of COVID-19 on the curative treatment of prostate cancer: a national cross-sectional study

BackgroundCOVID-19 pandemic affected access to cancer treatment worldwide. However, there is a lack of data about the impact in developing countries. The objective was to evaluate COVID-19 impact on curative prostate cancer (Pca) treatment in Brazil.Materials and methodsWith data extracted from the Brazilian Ministry of Health database, the Non-COVID and COVID periods were analyzed to compare the absolute number of radical prostatectomy (RP) and radiotherapy (RT) executed in the country and regions.ResultsWith data from 50,169 Pca patients (Non-COVID = 28,106 cases and COVID = 22,063) treated with RP or RT in Brazil, a significant decline in patients receiving RT or RP (−6.043 cases; p = 0.0001) was detected. Both treatment procedures (RT or PR) were reduced in all five Brazilian regions comparing the Non-COVID and COVID periods. Overall, there was a reduction on RP and RT procedures in 92% (24/25) and 76% (19/25) of the evaluated states, respectively. Comparing the variation of RT and RP per state between COVID and Non-COVID period, there is a significant difference (−18.6% vs. −29%, p = 0.03) with a higher negative impact on the RP group. The RT and RP variation had no significant relationship with the incidence of COVID cases in the states. Limitations include the non-evaluation of treatment combinations, the impact of hypofractionated radiotherapy, and other factors influencing the treatment choice.ConclusionsDuring the COVID-19 pandemic, the curative treatment with RP and RT of Pca was abruptly limited and affected. However, the number of RP was more impacted than RT during the COVID period.     

Complications after breast reconstruction with alloplastic material in breast cancer patients submitted or not to post mastectomy radiotherapy

Background and purposeBreast reconstruction following mastectomy is a relevant element of breast cancer treatment. The purpose of this study was to evaluate the influence of radiotherapy (RT) on local complications in patients with breast cancer that had undergone breast reconstruction with alloplastic material.Materials and methodsRetrospective study of breast cancer patients submitted to mastectomy and breast reconstruction from 2009 to 2013. Clinical and treatment variables were correlated with early and late complications.Results251 patients were included; mean age was 49.7 (25 to 78) years. Reconstruction was immediate in 94% of the patients, with 88% performed with a temporary tissue expander. Postoperative radiotherapy (RT) was delivered to 167 patients (66.5%). Early complications were present in 26.3% of the patients. Irradiated patients presented 5.4% incidence of late complications versus 2.4% for non-irradiated patients (p = 0.327). Diabetes (OR = 3.41 95% CI: 1.23–9.45, p = 0.018) and high body mass index (BMI) (OR = 2.65; 95% CI: 1.60–4.37, p < 0.0001) were the main risk factors. The overall incidence of late complications was 4.4%, with predominance of severe capsular contracture (8/11). Arterial hypertension (OR = 4.78; 95% CI: 1.97–11.63, p = 0.001), BMI (OR = 0.170; 95% CI: 0.048–0.607, p = 0.006) and implant placement (OR = 3.55; 95% CI: 1.26–9.99, p = 0.016) were related to late complications.ConclusionsThe overall rate of complications was low in this population. Radiotherapy delivery translated into a higher but not statistically significant risk of late complications when compared with the non-irradiated patients. Already well-known clinical risk factors for complications after breast reconstruction were identified.
