Established and new horizons in radiotherapy for breast cancer.

Modern advances in diagnostics, surgery, systemic therapies, and radiotherapy (RT) have drastically revolutionized treatment strategies for breast cancer. This review outlines current and evolving treatment paradigms for RT in the breast-conserving therapy and post-mastectomy setting. In early-stage breast cancer, there is active investigation in expanding eligibility for omission of RT in women with more biologically favorable tumors and growing options to effectively irradiate less breast tissue and shorten RT treatment courses. For locally advanced breast cancer, we discuss several patient cohorts in which the necessity of post-mastectomy RT (PMRT) is commonly debated. Ongoing efforts to better refine indications for PMRT and evaluate the feasibility of hypofractionated PMRT are being studied. Metastasis-directed therapy with ablative RT is an emerging topic of interest in many cancers, including its role and impact in oligometastatic breast cancer. In this review, we will discuss the rationale for current standard of care and address in greater detail the aforementioned concepts.

Development and Pilot Implementation of a Remote Monitoring System for Acute Toxicity Using Electronic Patient-Reported Outcomes for Patients Undergoing Radiation Therapy for Breast Cancer.

PURPOSE: We aimed to develop and study the implementation of a remote system for toxicity assessment and management of acute side effects of breast radiation using electronic patient-reported outcomes (ePROs). METHODS AND MATERIALS: A response-adapted Patient-Reported Outcomes Common Terminology Criteria for Adverse Events-based assessment for breast radiation toxicity was administered weekly during and for 8 weeks after radiation from June 2019 to July 2020. The care team received alerts when "severe" symptoms were reported by patients, who were then contacted. Treatment, clinic, and sociodemographic characteristics were abstracted from patient records. A subsample of patients and care team members was qualitatively interviewed at follow-up. RESULTS: Overall, 5787 assessments were sent to 678 patients, of whom 489 (72%) completed 2607 assessments (45%). Moderate or greater toxicity was reported by 419 responders (86%; 95% CI, 82%-89%). Clinician alerts for severe toxicity were generated for 264 assessments among 139 unique patients, of which 83% occurred posttreatment. The proportion of surveys that prompted an alert was significantly higher after treatment (219 [13%]) than during treatment (45 [5%]) (P < .001). Survey completion rates in the posttreatment period were higher among patients undergoing partial breast irradiation than postmastectomy radiation (incidence rate ratio, 0.70; 95% CI, 0.60-0.81) (P < .001) despite these patients experiencing less severe toxicity. Interviews (15) found that patients had a positive experience with ePROs, although many thought the primary purpose was for research rather than symptom management. CONCLUSIONS: With the majority of toxicity occurring after breast radiation has ended, remote symptom monitoring with ePROs appears to fill a gap in clinical practice, particularly for patients undergoing shorter courses of radiation. It is important to properly onboard patients and explain that the purpose of ePROs is to aid clinical care. Further research is needed to determine whether the costs associated with ePROs can be offset by reducing routine clinic visits and whether this approach is acceptable and appropriate.

A Practical Guide for Navigating the Design, Build, and Clinical Integration of Electronic Patient-Reported Outcomes in the Radiation Oncology Department.

The development and integration of electronic patient-reported outcomes (ePROs) into the radiation oncology clinic workflow provide novel opportunities, accompanied by unique design considerations and implementation challenges. The processes required for implementation of ePROs are entirely distinct from standard paper-based surveys, with the majority of time devoted to conception and design before initiating questionnaire build, detailed workflow process mapping including development of new workflows, comprehensive communication of the vision between providers and the information technology team, and quality assurance. Based on our experience with implementation of ePROs in our radiation oncology department, we developed a stepwise framework for approaching ePRO conceptual design, build, workflow integration, and the electronic health record interface. Here, we provide a guide for the numerous considerations, decision points, and solutions associated with the implementation of ePROs in the radiation oncology department setting. Although various ePRO tools and electronic health record capabilities impose different requirements, opportunities, and limitations, the conceptual processes and many of the electronic build considerations are broadly applicable.

The Declining Residency Applicant Pool: A Multi-Institutional Medical Student Survey to Identify Precipitating Factors.

PURPOSE: The purpose of our study was to better understand and identify concerns that may be responsible for the declining radiation oncology (RO) residency applicant pool. METHODS AND MATERIALS: All RO residency programs affiliated with a US medical school were asked to participate in the study survey. An optional and anonymous survey consisting of 12 questions was emailed to all graduating medical students in 2020 at the 12 allopathic medical schools that agreed to survey administration. Survey responses were collected from March to May 2020. RESULTS: The study consisted of 265 survey responses out of 1766 distributed to eligible medical students, resulting in a response rate of 15.0%. The majority of students reported no exposure to RO (60.8%) and never considered it as a career option (63.8%). Neutral perceptions of the field were more common (54.3%) than positive (39.6%) and negative (6.0%). The top factors attracting medical students to RO were perceptions of high salary, favorable lifestyle and workload, and technological focus. The top negative factors were the field's interplay with physics, competitive United States Medical Licensing Examination board scores for matched applicants, and the focus placed on research during medical school. In the subgroup of students who were interested in RO but ultimately applied to another specialty, the job market was the most salient concern. CONCLUSIONS: Finding a place for RO in medical school curricula remains a challenge, with most surveyed students reporting no exposure during their education. Concern over the job market was the primary deterrent for medical students interested in pursuing RO. For disinterested students who had not considered RO as a career option, the required physics knowledge was the main deterrent.

Impact of Open Access to Physician Notes on Radiation Oncology Patients: Results from an Exploratory Survey.

PURPOSE: There is an increasing effort to allow patients open access to their physician notes through electronic medical record portals. However, limited data exist on the impact of such access on oncology patients, and concerns remain regarding potential harms. Therefore, we determined the baseline perceptions and impact of open access to oncology notes on radiation oncology patients. METHODS AND MATERIALS: Patients receiving radiation therapy were provided instructional materials on accessing oncology notes at the time of their initial evaluation. Patients were prospectively surveyed to evaluate baseline interest and expectations before access and to determine the actual usage and impact at the end of their radiation treatment course. RESULTS: A total of 220 patients were surveyed; 136 (62%) completed the baseline survey, of which 88 (40%) completed the final survey. The majority of participants were age >60 years (n = 83; 61%), and 70 were male (51%). Before accessing the notes, the majority of patients agreed that open access to oncology notes would improve understanding of diagnosis (99%), understanding of treatment side effects (98%), reassurance about treatment goals (96%), and communication with family (99%). All patients who accessed the notes found them to be useful. After accessing the notes, approximately 96%, 94%, and 96% of patients reported an improved understanding of their diagnosis, an improved understanding of treatment side effects, and feeling more reassured about their treatment, respectively. Approximately 11%, 6%, and 4% of patients noted increased worry, increased confusion, and finding information they now regret reading, respectively. Patient age, sex, and specific cancer diagnoses were not predictive of experiencing negative effects from accessing the notes. CONCLUSIONS: Radiation oncology patients have a strong interest in open access to their physician notes, and the majority of patients expect and actually report meaningful benefits. These data support strategies to allow more patients with cancer access to their physicians' notes.

Content Validity of Anatomic Site-Specific Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) Item Sets for Assessment of Acute Symptomatic Toxicities in Radiation Oncology.

PURPOSE: To improve assessment of symptomatic toxicity in cancer clinical trials and complement clinician-based toxicity reporting, the US National Cancer Institute developed a measurement system called the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). The objective of this study was to examine the content validity of PRO-CTCAE in patients undergoing radiation therapy and to establish anatomic site-specific item sets for implementation in cancer research. METHODS AND MATERIALS: Patients receiving radiation to the brain, head and neck, breast, thorax, abdomen, or pelvis were recruited during the final week of radiation. Participants described side effects qualitatively and completed anatomic site-specific checklists indicating the presence or absence of symptomatic toxicities drawn from the PRO-CTCAE library. Items endorsed by ≥20% of participants were selected for inclusion. Symptomatic toxicities described qualitatively were content analyzed and summarized. Symptomatic toxicities not reflected in the PRO-CTCAE item library were tabulated. RESULTS: We conducted 389 interviews of patients receiving radiation to the brain (n = 46), head and neck (n = 69), breast (n = 134), thorax (n = 30), abdomen (n = 27), female pelvis (n = 36), or male pelvis (n = 47). Median age was 62 years; 62% were female. The 53 solicited PRO-CTCAE symptoms reflected all reported radiation-induced toxicities with the exception of phlegm/mucus production and mouth/throat pain with swallowing in patients receiving head and neck radiation, eye dryness/irritation in patients undergoing brain radiation, and obstructive urinary symptoms in men receiving pelvic radiation. The PRO-CTCAE items "skin burns" and "pain" require greater specificity to adequately reflect toxicities experienced during radiation. CONCLUSIONS: PRO-CTCAE demonstrates strong content validity as a measure of symptomatic toxicities in patients receiving radiation. These results provide empirical support for the definition of site-specific PRO-CTCAE item sets to assess the symptomatic toxicities of radiation therapy. The site-specific PRO-CTCAE item sets developed herein are currently being deployed in our department via an electronic platform to capture treatment-related toxicity.

The patient's perspective on breast radiotherapy: Initial fears and expectations versus reality.

BACKGROUND: Although the efficacy and toxicity of breast radiotherapy (RT) has been studied extensively, to the authors' knowledge little is known regarding the patient's perspective on the modern breast RT experience. To better inform future patients and providers, the authors explored patient perceptions of their RT experience. METHODS: Consecutive patients who were free of disease recurrence and who had been treated between 2012 and 2016 were surveyed regarding their original fears, how short-term and long-term toxicities compared with initial expectations, and how pretreatment beliefs concerning RT compared with the actual experience. RESULTS: A total of 502 patients were surveyed, with a response rate of 65% (327 patients). The median patient age and posttreatment follow-up was 59 years and 31 months, respectively. Approximately 83% of patients (269 patients) underwent breast conservation therapy. Although approximately 68% of patients (221 patients) endorsed that they initially had little to no knowledge regarding RT, approximately 47% (152 patients) reported that they had heard frightening stories. Approximately 2% of patients (6 patients) agreed that the negative stories they previously heard about RT were actually true. Approximately 92% of patients treated with breast conservation (247 patients) and 81% of patients who underwent mastectomy (47 patients) agreed with the statement "If future patients knew the real truth about RT, they would be less scared about treatment." Approximately 83% (272 patients) and 84% (274 patients), respectively, of all patients reported the overall severity of short-term and long-term side effects to be better than or as expected. CONCLUSIONS: Breast RT is associated with misconceptions and fears. Patients' experiences with modern breast RT appear to be superior to expectations, and the majority of patients in the current study agreed that their initial negative impressions were unfounded.

Assessing the Effect of Lifetime Contralateral Breast Cancer Risk on the Selection of Contralateral Prophylactic Mastectomy for Unilateral Breast Cancer.

INTRODUCTION: Contralateral prophylactic mastectomy (CPM) rates are rising, with fear implicated as a contributing factor. This study used a contralateral breast cancer (CBC) risk stratification tool to assess whether the selection of CPM is reflective of future CBC risk. PATIENTS AND METHODS: This retrospective study evaluated 404 women with unilateral breast cancer treated with breast conservation, unilateral mastectomy, or bilateral mastectomy within a single multidisciplinary clinic. Women were evaluated by the Manchester risk tool to calculate lifetime CBC risk. Logistic regression analysis was used to evaluate whether CBC risk was associated with CPM, and the clinical rationale for prophylactic mastectomy justification was recorded. RESULTS: Sixty-two percent underwent breast conservation, 18% unilateral mastectomy, and 20% bilateral mastectomy. In the CPM cohort, 36% had > 20% calculated lifetime CBC risk. In the invasive cohort, younger age (odds ratio 2.65, P < .0001) and genetic mutation positivity (odds ratio 35.39, P = .019) independently predicted CPM. Other contributing factors included benign contralateral breast findings (29%) and recommendations against breast conservation due to disease burden (28%). Six percent selected CPM as a result of an unsubstantiated fear regarding breast cancer. CONCLUSION: The majority of women (63%) who selected CPM had < 20% CBC risk. In these lower-risk women selecting CPM, factors increasing reasonable fear dominated surgical choice (81% of this subset).

Predictors associated with MRI surveillance screening in women with a personal history of unilateral breast cancer but without a genetic predisposition for future contralateral breast cancer.

PURPOSE: For women with a personal history of breast cancer (PHBC), no validated mechanisms exist to calculate future contralateral breast cancer (CBC) risk. The Manchester risk stratification guidelines were developed to evaluate CBC risk in women with a PHBC, primarily for surgical decision making. This tool may be informative for the use of MRI screening, as CBC risk is an assumed consideration for high-risk surveillance. METHODS: Three hundred twenty-two women with a PHBC were treated with unilateral surgery within our multidisciplinary breast clinic. We calculated lifetime CBC risk using the Manchester tool, which incorporates age at diagnosis, family history, genetic mutation status, estrogen receptor positivity, and endocrine therapy use. Univariate and multivariate logistic regression analyses (UVA/MVA) were performed, evaluating whether CBC risk predicted MRI surveillance. RESULTS: For women with invasive disease undergoing MRI surveillance, 66% had low, 23% above-average, and 11% moderate/high risk for CBC. On MVA, previous mammography-occult breast cancer [odds ratio (OR) 18.95, p < 0.0001], endocrine therapy use (OR 3.89, p = 0.009), dense breast tissue (OR 3.69, p = 0.0007), mastectomy versus lumpectomy (OR 3.12, p = 0.0041), and CBC risk (OR 3.17 for every 10% increase, p = 0.0002) were associated with MRI surveillance. No pathologic factors increasing ipsilateral breast cancer recurrence were significant on MVA. CONCLUSIONS: Although CBC risk predicted MRI surveillance, 89% with invasive disease undergoing MRI had <20% calculated CBC risk. Concerns related to future breast cancer detectability (dense breasts and/or previous mammography-occult disease) predominate decision making. Pathologic factors important for determining ipsilateral recurrence risk, aside from age, were not associated with MRI surveillance.

Considerations for Quality Improvement in Radiation Oncology Therapy for Patients with Uncomplicated Painful Bone Metastases.

Background: There is an increasing need for evidence-based efficiency in providing a growing amount of cancer care. One example of a quality gap is the use of multiple-fraction palliative radiation for patients with advanced cancer who have uncomplicated bone metastases; evidence suggests similar pain outcomes for treatment regimens with a lower burden of treatments. Methods: During the first phase of quality improvement work, we used RAND/UCLA appropriateness methodology to understand how radiation oncologists at one academic medical center rate the appropriateness of different treatment regimens for painful uncomplicated bone metastases. We compared radiation oncologist appropriateness ratings for radiation treatments with radiation therapy provided by these oncologists to patients with painful bone metastases between July 2012 and June 2013. Results: Appropriateness ratings showed that single-fraction (8 Gy) treatment (a low burden treatment) was consistently considered an appropriate option to treat a variety of uncomplicated bone metastases. The use of >10 fractions was consistently rated as inappropriate regardless of other factors. Eighty-one patients receiving radiation therapy for painful bone metastases during the study period had an available medical record for chart abstraction. Almost one-third of metastases were considered complicated because of a concern of spinal cord compression, a history of prior irradiation, or an associated pathological fracture. Among uncomplicated bone metastases, 25% were treated with stereotactic body radiation treatment (SBRT). Among the 54 uncomplicated bone metastases treated with conformal radiation, only one was treated with single-fraction treatment and 32% were treated with greater than 10 fractions. Conclusions: Treatment at the study site demonstrates room for improvement in providing low-burden radiation oncology treatments for patients with painful bone metastases. Choosing a radiation treatment schedule for patients with advanced cancer and painful bone metastases requires consideration of many medical and patient-centered factors. Our experience suggests that it will take more than the existence of guidelines to change practice in this area.

Increasing Appropriate BRCA1/2 Mutation Testing: The Role of Family History Documentation and Genetic Counseling in a Multidisciplinary Clinic.

BACKGROUND: Findings show that 5-10 % of women with a diagnosis of breast cancer (BCa) have actionable genetic mutations. The National Comprehensive Cancer Network guidelines for testing to detect BRCA1/2 mutations include personal history (PH) variables such as age of 45 years or younger and a family history (FH) variables. Rates of FH documentation and overall rates of appropriate referral for genetic testing are low, ranging from about 30 to 60 %. The authors hypothesized that an upfront FH documentation and inclusion of a genetics counselor in a multidisciplinary clinic (MDC) setting would increase rates of appropriate referral for genetic testing. METHODS: The study enrolled 609 consecutive women with non-metastatic BCa seen in consultation between June 2012 and December 2015 at a multidisciplinary clinic. Rates of FH documentation and referral for genetic testing to detect BRCA1/2 mutations were assessed before and after inclusion of a genetic counselor in the MDC. RESULTS: The rates of FH documentation and appropriate referral were 100 and 89 %, respectively. Half (50 %) of the patients had only FH-based indications for testing. All the patients with PH-based indications were referred. The inclusion of a genetic counselor significantly increased appropriate referral rates among those with only FH-based indications (62 vs. 92 %) and overall (80 vs. 96 %) (p < 0.0001 for both). Among the 12 % of the patients with actionable mutations, 60 % were 45 years of age or younger, whereas 30 % had only FH-based testing indications. CONCLUSIONS: This report shows substantially higher FH documentation and appropriate genetic testing rates than prior reports. Many patients with indications for genetic testing may have only FH-based indications for testing, and this subset may account for the sizable proportion of patients with newly diagnosed BCa who have actionable mutations.

Management of Breast Sarcoma.

Breast sarcomas are exceptionally rare mesenchymal neoplasms composed of many histologic subtypes. Therapy is guided by principles established in the management of extremity sarcomas. The anatomic site does influence treatment decisions, particularly the surgical management. Surgery should be undertaken with the aim of achieving a widely negative margin. Selected patients can be managed with breast-conserving surgery. Breast reconstruction is increasingly being undertaken for selected patients. Radiation therapy and chemotherapy are used selectively for large, high-grade sarcomas for which there is significant concern for local and distant recurrence.

Clinical Indicators of Psychosocial Distress Predict for Acute Radiation-Induced Fatigue in Patients Receiving Adjuvant Radiation Therapy for Breast Cancer: An Analysis of Patient-Reported Outcomes.

PURPOSE: To assess the magnitude and predictors of patient-reported fatigue among breast cancer patients receiving radiation therapy (RT). METHODS AND MATERIALS: Patients receiving breast RT completed a survey querying fatigue at each weekly on-treatment visit. Patient-reported fatigue severity and interference was assessed on an ordinal scale of 0 to 4, using a validated scoring system. Baseline anxiety and depression scores were also obtained. The kinetics of mean fatigue scores per week and the maximum fatigue scores over the course of the entire treatment were assessed, and clinical predictors were identified by univariate and multivariate regression. RESULTS: The average fatigue severity and interference scores were 0.6 and 0.46. The average fatigue scores increased to an equivalent extent from week to week, with expected increases of 0.99 in fatigue severity and 0.85 in interference over 7 weeks. Patients treated with hypofractionated RT (HF-RT) versus conventionally fractionated RT (CF-RT) had significantly fewer maximum fatigue severity or interference scores that were >2 (ie, severe or very severe; 29% vs 10% for severity, and 26% vs 8% for interference, P<.01). Age ≤45 years, presence of psychiatric/pain-related comorbidities, and baseline sadness and anxiety severity were predictive of average and maximum fatigue scores (P<.05), but variables related to treatment intensity (eg, mastectomy vs lumpectomy, chemotherapy use, radiation target volumes) and other host factors (working, children, marital status, proximity to RT facility) were not. CONCLUSION: Patient-reported fatigue modestly increases over RT courses, with less maximum fatigue reported with HF-RT. Younger age and baseline sadness, anxiety, and psychiatric/pain-related comorbidities are powerful predictors of fatigue, whereas other factors, such as treatment intensity, are not. Future studies will investigate interventions for patients at high risk for fatigue.

Postmastectomy radiation therapy after neoadjuvant chemotherapy: review and interpretation of available data.

Postmastectomy radiotherapy (PMRT) has been shown to decrease locoregional recurrence and improve overall survival in patients with tumors greater than 5 cm or positive nodes. Because neoadjuvant chemotherapy (NAC) can cause significant downstaging, the indications for PMRT in the setting of NAC remain controversial and thus careful consideration of clinical stage at presentation, pathologic response to NAC, and other clinical characteristics, such as grade and biomarker status is required. The current review synthesizes both prospective and retrospective data to provide evidence for recommending PMRT after NAC for patients presenting with cT3-4 disease, cN2-3 disease, and residual nodal disease, as well as rationale for omitting PMRT in patients with cT1-2N0-1 disease who achieve a pathologic complete response. Other scenarios, including nodal complete response in the presence of other risk factors, are also explored. The topics of pre-NAC clinical staging and pathologic axillary nodal staging are reviewed, and radiation portal design is briefly discussed.

Value: a framework for radiation oncology.

In the current health care system, high costs without proportional improvements in quality or outcome have prompted widespread calls for change in how we deliver and pay for care. Value-based health care delivery models have been proposed. Multiple impediments exist to achieving value, including misaligned patient and provider incentives, information asymmetries, convoluted and opaque cost structures, and cultural attitudes toward cancer treatment. Radiation oncology as a specialty has recently become a focus of the value discussion. Escalating costs secondary to rapidly evolving technologies, safety breaches, and variable, nonstandardized structures and processes of delivering care have garnered attention. In response, we present a framework for the value discussion in radiation oncology and identify approaches for attaining value, including economic and structural models, process improvements, outcome measurement, and cost assessment.

Pretreatment weight status and weight loss among head and neck cancer patients receiving definitive concurrent chemoradiation therapy: implications for nutrition integrated treatment pathways.

PURPOSE: The purpose was to examine the effect of pretreatment weight status on loco-regional progression for patients with squamous cell carcinoma of the head and neck (SCCHN) after receiving definitive concurrent chemoradiation therapy (CCRT). METHODS: In an expanded cohort of 140 patients, we retrospectively reviewed weight status and loco-regional progression of SCCHN patients treated with CCRT between 2004 and 2010. RESULTS: Pretreatment ideal body weight percentage (IBW%) was statistically significantly different for patients with disease progression than for those without progression (p = 0.02) but was not an independent predictor of progression. Median pretreatment IBW% was 118 (72-193) for the progression-free group and was 101.5 (73-163) for the group with progression. Both groups suffered clinically severe weight loss of approximately 9 % from baseline to end treatment. CONCLUSIONS: Pretreatment weight status, a very crude indicator of nutrition status, may have prognostic value in patients with SCCHN undergoing definitive CCRT. Inadequate nutritional status in these patients has been associated with poor clinical outcomes and decreased quality of life. Based on this report and others, the best next steps include routine validated malnutrition screening and the testing of evidence-based nutrition care protocols with the goals of minimizing weight loss and improvement of quality of life.

Quantification of the effect of treatment duration on local-regional failure after definitive concurrent chemotherapy and intensity-modulated radiation therapy for squamous cell carcinoma of the head and neck.

BACKGROUND: The purpose of this study was to quantify the effect of treatment duration on locoregional progression after definitive concurrent chemoradiation (CCRT) for squamous cell carcinoma of the head and neck (SCCHN). METHODS: We conducted a retrospective chart review of patients treated between 2004 and 2010. After a prior analysis, measures were taken to limit therapy beyond 7 weeks. Comparison of outcomes were made between cohorts 1 (2004-2007, n = 78) and 2 (2007-2010, n = 62). RESULTS: Median therapy duration was statistically significantly different between cohorts as follows: 51 days, cohort 1 and 46 days, cohort 2 (p < .01). Locoregional progression in cohorts 1 and 2 was 19% and 5% (p = .01), respectively. On multivariate analysis, patients with prolonged treatment (≥57 days) had an 8-fold increase in risk of locoregional progression compared to patients who completed on time (p < .01). CONCLUSION: Treatment duration was a significant predictor of locoregional progression in patients with SCCHN who received definitive CCRT.

Delivering affordable cancer care in high-income countries.

The burden of cancer is growing, and the disease is becoming a major economic expenditure for all developed countries. In 2008, the worldwide cost of cancer due to premature death and disability (not including direct medical costs) was estimated to be US$895 billion. This is not simply due to an increase in absolute numbers, but also the rate of increase of expenditure on cancer. What are the drivers and solutions to the so-called cancer-cost curve in developed countries? How are we going to afford to deliver high quality and equitable care? Here, expert opinion from health-care professionals, policy makers, and cancer survivors has been gathered to address the barriers and solutions to delivering affordable cancer care. Although many of the drivers and themes are specific to a particular field-eg, the huge development costs for cancer medicines-there is strong concordance running through each contribution. Several drivers of cost, such as over-use, rapid expansion, and shortening life cycles of cancer technologies (such as medicines and imaging modalities), and the lack of suitable clinical research and integrated health economic studies, have converged with more defensive medical practice, a less informed regulatory system, a lack of evidence-based sociopolitical debate, and a declining degree of fairness for all patients with cancer. Urgent solutions range from re-engineering of the macroeconomic basis of cancer costs (eg, value-based approaches to bend the cost curve and allow cost-saving technologies), greater education of policy makers, and an informed and transparent regulatory system. A radical shift in cancer policy is also required. Political toleration of unfairness in access to affordable cancer treatment is unacceptable. The cancer profession and industry should take responsibility and not accept a substandard evidence base and an ethos of very small benefit at whatever cost; rather, we need delivery of fair prices and real value from new technologies.

Roles and types of radiation in breast cancer treatment: early breast cancer, locoregionally advanced, and metastatic disease.

PURPOSE OF REVIEW: To describe the current role of radiation therapy and specific types of radiation therapy used in the management of early stage, locoregionally advanced, and metastatic breast cancer. RECENT FINDINGS: The role of radiation therapy in the management of breast cancer has not changed in recent decades, however methods of treatment delivery have advanced considerably. Hypofractionation and accelerated partial breast irradiation, which substantially reduce radiation treatment duration, have emerged as appropriate alternatives to conventional whole breast radiation in select patient subsets, and intensity modulated radiation therapy, breathing-adapted radiation therapy, and prone-positioning technique address challenging anatomic issues and reduce treatment-associated toxicity. Stereotactic radiosurgery and stereotactic body radiation therapy continue to advance the management of distant metastatic disease. SUMMARY: Radiation therapy plays a significant role in the management of early stage, locoregionally advanced, and metastatic breast cancer. Technological advances are allowing for greater patient convenience and comfort in locoregional radiation therapy delivery and for expanded radiation therapy indications in the setting of metastatic disease.

Increasing age and treatment modality are predictors for subsequent diagnosis of bladder cancer following prostate cancer diagnosis.

PURPOSE: To determine the effect of prostate cancer therapy (surgery or external beam irradiation, or both or none) on the actuarial incidence of subsequent bladder cancer. METHODS AND MATERIALS: The Surveillance, Epidemiology, and End Results registry from 1973 to 2005 was analyzed. Treatment was stratified as radiotherapy, surgery, both surgery and adjuvant radiation, and neither modality. Brachytherapy was excluded. RESULTS: In all, 555,337 prostate carcinoma patients were identified; 124,141 patients were irradiated; 235,341 patients were treated surgically; 32,744 patients had both surgery and radiation; and 163,111 patients received neither modality. Bladder cancers were diagnosed in: 1,836 (1.48%) men who were irradiated (mean age, 69.4 years), 2,753 (1.09%) men who were treated surgically (mean age, 66.9 years); 683 (2.09%) men who received both modalities (mean age, 67.4 years), and 1,603 (0.98%) men who were treated with neither modality (mean age, 71.8 years). In each treatment cohort, Kaplan-Meier analyses showed that increasing age (by decade) was a significant predictor of developing bladder cancer (p < 0.0001). Incidence of bladder cancer was significantly different for either radiation or surgery alone versus no treatment, radiation versus surgery alone, and both surgery and radiation versus either modality alone (p < 0.0001). On multivariate analysis, age and irradiation were highly significant predictors of being diagnosed with bladder cancer. CONCLUSIONS: Following prostate cancer, increasing age and irradiation were highly significant predictors of being diagnosed with bladder cancer. While use of radiation increased the risk of bladder cancer compared to surgery alone or no treatment, the overall incidence of subsequent bladder cancer remained low. Routine bladder cancer surveillance is not warranted.
