An Intracranial Hemorrhage Wrapped in an Enigma

An 88-year-old man with Alzheimer's dementia who previously received a diagnosis of solitary Fuhrman grade 2 renal cell carcinoma1 managed with active surveillance presented to the emergency department for progressive left-sided headache and difficulty recognizing numbers and letters. He and his family denied history of trauma, fall, or anticoagulant use. This occurred 1 week after presenting to the same emergency department with a headache and being discharged home after negative head computed tomography, 2 months after spontaneous subarachnoid hemorrhage involving the right central sulcus, and 11 months after transient ischemic attack symptoms with negative workup

Evidence-based methodology for obtaining commercial insurance coverage of stereotactic radiosurgery for intractable epilepsy

Objectives: The coverage policies of many commercial insurers in the United States do not include coverage of stereotactic radiosurgery (SRS) for intractable epilepsy despite recent Level I evidence supporting its efficacy. We sought to assess the efficacy of an evidence-based methodology in obtaining coverage approval of SRS for intractable epilepsy. Patients and methods: The clinical policy guidelines from five of the largest United States commercial insurers were reviewed for their language regarding coverage of SRS for epilepsy. An evidence-based questionnaire was created for temporal lobe epilepsy and extratemporal lobe epilepsy based on recent evidence. Telephone interviewers of Insurers assessed the likelihood of SRS coverage for an epilepsy patient meeting the clinical inclusion criteria in the questionnaire. This likelihood was assessed numerically based on interviewee response (2 = yes, 1 = dependent on peer-to-peer, 0 = no). Results: Of the five policy guidelines, none included literature more recent than 2017. For TLE, 3/5 insurance companies indicated likely SRS coverage; 2/5 indicated peer-to-peer discussion dependence for patients meeting questionnaire criteria for a score of 8/10. For extratemporal TLE, 2/5 companies indicated likely SRS coverage and 3/5 indicated peer-to-peer discussion dependence for a total score of 7/10. Conclusion: Creation of an evidence-based methodology in approaching commercial insurers greatly increased the likelihood of SRS coverage for an indication (intractable epilepsy) widely perceived as investigational. These results should pave the way for epilepsy patients to receive coverage should they be appropriate SRS candidates

RADIANS: A Multidisciplinary Central Nervous System Clinic Model for Radiation Oncology and Neurosurgery Practice

Background Radiation therapy for central nervous system disease commonly involves collaboration between Radiation Oncology and Neurosurgery. We describe our early experience with a multidisciplinary clinic model. Methods In 2016, the novel RADIANS (RADIation oncology And NeuroSurgery) clinic model was initiated at a community hospital. Disease and treatment demographics were collected and analyzed. Patient satisfaction was assessed via a blinded survey questionnaire. Results Forty-two patients have been seen since the inception of RADIANS. The median age was 65; and the median patient distance from RADIANS was 42.7 miles (mean = 62.6; range = 0.7–285). Half of the patients traveled >50 miles to receive care, and >80% were seen for central nervous system metastases. Of the patients receiving radiation, 75% received stereotactic radiosurgery/stereotactic body radiation therapy. The mean overall satisfaction from 0 (not satisfied) to 5 (very satisfied) was 4.8. Conclusions The RADIANS clinic model has proved viable and well-liked by patients in a community setting, with the majority of radiation therapy administered being stereotactic radiosurgery/stereotactic body radiation therapy rather than conventional fractionation

Impact of Travel Distance on Radiation Treatment Modality for Central Nervous System Disease

Background Stereotactic body radiation therapy (SBRT) has emerged as a popular alternative to conventional radiation therapy (RT) over the past 15 years. Unfortunately, the impact of patient distance from radiation treatment centers and utilization of SBRT versus conventional RT has been sparsely investigated. This report represents the first analysis of the impact of patient distance on radiation treatment modality for central nervous system (CNS) disease. Materials and Methods Since the inception of our RADIation oncology And Neuro-Surgery (RADIANS) multidisciplinary clinic at a community hospital in 2016, 27 patients have received either SBRT or conventional RT as their sole radiation treatment modality for CNS disease. Twenty-four (88.9%) presented with metastatic disease. Fisher’s exact test evaluated the relationship between patient residence from treatment (in miles) and radiation treatment modality received. Results Mean patient distance from our RADIANS clinic was 50.6 miles (median = 15.3). Twenty-one patients (77.8%) received SBRT; the remaining six received conventional RT. Mean patient distance from SBRT was 63.6 miles, and mean patient distance for conventional RT was 5.1 miles; this finding was statistically significant (p = 0.0433; 95% confidence interval = 1.9–115.1). Conclusion Our findings indicate that patients with CNS disease who receive SBRT over conventional RT are statistically more likely to reside further from treatment centers. This is similar to findings of national studies comparing proton versus photon treatment for pediatric solid malignancies. The results from our work have implications for neuro-oncology treatment and the development of community hospital-based clinic models similar to RADIANS in the future

Dramatic polarization in genitourinary expert opinions regarding the clinical utility of positron emission tomography (PET) imaging in prostate cance

OBJECTIVES: To ascertain the opinions of North American genitourinary (GU) experts regarding inclusion of technologies such as prostate - specific membrane antigen (PSMA) and C - 11 choline positron emission tomography (PET) into routine practice. MATERIALS AND METHODS: A survey was distributed to North American GU experts. Questions pertained to the role of PSMA and C - 11 PET in PCa management. Participants were categorized as "supporters" or "opponents" of incorporation of novel imaging techniques. Opinions were correlated with practice patterns. RESULTS: Response rate was 54% and we analyzed 42 radiation oncologist respondents. 17 participants (40%) have been in practice for > 20 years and 38 (90%) practice at an academic center. 24 (57%) were supporters of PSMA and 29 (69%) were supporters of C - 11. Supporters were more likely to treat pelvic nodes (88% vs. 56%, p < 01) and trended to be more likely to treat patients with moderate or extreme hypofractionation (58% vs. 28%, p = 065). Supporters trended to be more likely to offer brachytherapy boost (55% vs. 23%, p = 09), favor initial observation and early salvage over adjuvant radiation (77% vs. 55%, p = 09), and to consider themselves expert brachytherapists (69% vs. 39%, p = 09). CONCLUSIONS: There is a polarization among GU radiation oncology experts regarding novel imaging techniques. A correlation emerged between support of novel imaging and adoption of treatment approaches that are clinically superior or less expensive. Pre - existing biases among GU experts on national treatment - decision panels and leaders of cooperative group studies may affect the design of future studies and influence the adoption of these technologies in clinical practice

Analysis of pre-residency research productivity, dual degree status, and gender distribution of underrepresented minorities among a current United States radiation oncology junior resident class

Background: Among the most competitive medical subspecialties, representation of underrepresented minorities (African-American race and/or Hispanic ethnicity) among resident trainees has historically been low compared to their United States Census general population representation. Research productivity and dual degree status may impact residency applicant competitiveness. To date, such an analysis has yet to be performed in Radiation Oncology. Methods: A list of radiation oncology residents from the graduating class of 2022 was obtained through internet searches. Demographics included were gender and dual degree status. Research productivity was calculated using the number of pre-residency peer-reviewed publications (PRP). Fisher's exact test was used for statistical analysis. Results: Of the 179 residents evaluated from the 2022 class, eleven (6.1%) were underrepresented minorities. Compared to the remainder of the class, underrepresented minorities had a lower proportion of men (63.6% versus 69.3%), a higher proportion of dual degrees (45.5% versus 28.6%), and a lower proportion of MD-PhD degrees (9.1% versus 17.2%). Underrepresented minorities had a higher proportion of residents with at least two PRP (72.7% versus 57.1%) and a lower proportion of residents with no PRP (18.2% versus 24.4%). None of these differences reached statistical significance (p > 0.05). Conclusion: Underrepresented minorities were comparable to the remainder of their Radiation Oncology resident class regarding gender distribution, dual degrees status, and likelihood of having at least two peer-reviewed publications cited in PubMed during the calendar year of residency application. Further studies will be needed to determine how these findings translate into future scholarly activity and post-graduate career choice

Spine Patient Optimal Radiosurgery Treatment for Symptomatic Metastatic Neoplasms (SPORTSMEN): a randomized phase II study protocol

Background: Approximately 40% of patients with metastatic cancer will have spinal metastatic disease. Historically treated with external beam radiation therapy (EBRT) with limited durability in pain control, the increased lifespan of this patient population has necessitated more durable treatment results via spine radiosurgery/stereotactic body radiation therapy (SBRT). The goal of this study is to assess three-month pain freedom rates via the Spine Patient Optimal Radiosurgery Treatment for Symptomatic Metastatic Neoplasms (SPORTSMEN) randomized trial. Materials and methods: This study is a prospective randomized three-arm phase II trial which will recruit patients with symptomatic spine metastases. All patients will be randomized to standard-of care SBRT (24 Gy in 2 fractions), single-fraction SBRT (19 Gy in 1 fraction), or EBRT (8 Gy in 1 fraction), with the primary endpoint of three-month pain freedom (using the Brief Pain Inventory). We expect that SPORTSMEN will help definitively answer the efficacy of spine SBRT versus EBRT for achieving pain freedom, while defining the safety and efficacy of 19 Gy single-fraction spine SBRT. Local control will be defined according to Spine Response Assessment in Neuro-Oncology (SPINO) criteria. Discussion: This is the first phase II trial to objectively assess optimal spine SBRT dosing in the treatment of symptomatic spine metastatic disease, while assessing spine SBRT versus EBRT. Findings should allow for better determination of the efficacy of two-fraction spine SBRT versus EBRT in the United States, as well as for the novel single-fraction 19 Gy spine SBRT regimen in patients with symptomatic spine metastases. Trial Registration: Clinicaltrials.gov identifier: NCT05617716 (registration date: November 14, 2022)

Navigator utilization among African-American Breast cancer patients at a Comprehensive Cancer Center

Background: Patient navigation has been demonstrated to improve access to standard-of-care oncologic therapy. However, many patients — particularly those of African-American race — often do not have access to navigation upon receiving a diagnosis of cancer. As the most common cancer among African-American women is breast cancer, we sought to assess the rate of patient navigation among African-American breast cancer patients at our institution, which resides in a regional ZIP code comprised of 46% African-American residents. Materials and methods: African-American breast cancer patients who had been discussed at our weekly breast cancer multidisciplinary tumor board over a recent three-month period were assessed by a patient navigator representing the Navigator-Assisted Hypofractionation (NAVAH) program to determine their access to navigation in their cancer care. Responses were assessed from a breast cancer support group and culled to determine a baseline proportion of navigation utilization. Results: A total of 18 women of African-American race having been diagnosed with breast cancer were identified and assessed. Of these a total of 4 noted that they had received navigation, yielding a navigation utilization percentage of 22.2% among African-American breast cancer patients at our institution. Conclusion: The rate of navigation utilization among African-American breast cancer patients is poor. Despite our center residing in a region comprised of increased African-Americans, such predominance has not translated into optimizing navigation access for African-American breast cancer patients. This 22% rate of navigation utilization serves as a starting benchmark for initiatives such as the NAVAH program to provide tangible improvement in this patient population
