Item ACR Appropriateness Criteria® Hodgkin Lymphoma-Favorable Prognosis Stage I and II(Wolters Kluwer, 2016-12-01) Dhakal, Sughosh; Advani, Ranjana; Ballas, Leslie K.; Dabaja, Bouthaina S.; Flowers, Christopher R.; Ha, Chul S.; Hoppe, Bradford S.; Mendenhall, Nancy P.; Metzger, Monika L.; Plastaras, John P.; Roberts, Kenneth B.; Shapiro, Ronald; Smith, Sonali M.; Terezakis, Stephanie A.; Winkfield, Karen M.; Younes, Anas; Constine, Louis S.; Expert Panel on Radiation Oncology–Lymphoma; Radiation Oncology, School of MedicineThis topic addresses the treatment of newly diagnosed patients with favorable prognosis stage I and II Hodgkin lymphoma. In most cases, combined modality therapy (chemotherapy followed by involved site radiation therapy) constitutes the current standard of care. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. By combining the most recent medical literature and expert opinion, this revised guideline can aid clinicians in the appropriate use of combined modality therapy for favorable prognosis stage I and II Hodgkin lymphoma. Increasing information about the late effects of treatment has led to attempts to decrease toxicity by using less chemotherapy (decreased duration and/or intensity or different agents) and less radiation therapy (reduced volume and/or dose) while maintaining excellent efficacy.Item ACR Appropriateness Criteria® Recurrent Hodgkin Lymphoma(Elsevier, 2016-12-15) Winkfield, Karen M.; Advani, Ranjana H.; Ballas, Leslie K.; Dabaja, Bouthaina S.; Dhakal, Sughosh; Flowers, Christopher R.; Ha, Chul Soo; Hoppe, Bradford S.; Mansur, David B.; Mendenhall, Nancy P.; Metzger, Monika L.; Plastaras, John P.; Roberts, Kenneth B.; Shapiro, Ronald; Smith, Sonali M.; Terezakis, Stephanie A.; Younes, Anas; Constine, Louis S.; Radiation Oncology, School of MedicineThis topic addresses the management of recurrent Hodgkin lymphoma. While autologous stem cell transplantation may be appropriate for select cases of recurrent disease following comprehensive combined-modality therapy, other options exist for patients treated with lower-dose therapy for early-stage disease. Additionally, innovative targeted therapies provide newer salvage options to consider. The American College of Radiology Appropriateness Criteria® are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation, or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. By combining the most recent medical literature and expert opinion, this revised guideline can aid clinicians in the complex decisionmaking associated with the management of recurrent Hodgkin lymphoma.Item Early Cardiac Effects of Contemporary Radiation Therapy in Patients With Breast Cancer(Elsevier, 2020) Clasen, Suparna C.; Shou, Haochang; Freedman, Gary; Plastaras, John P.; Taunk, Neil K.; Teo, Boon-Keng Kevin; Smith, Amanda M.; Demissei, Biniyam G.; Ky, Bonnie; Medicine, School of MedicinePurpose To characterize the early changes in echocardiographically derived measures of cardiac function with contemporary radiation therapy (RT) in breast cancer and to determine the associations with radiation dose-volume metrics, including mean heart dose (MHD). Methods and Materials In a prospective longitudinal cohort study of 86 patients with breast cancer treated with photon or proton thoracic RT, clinical and echocardiographic data were assessed at 3 time points: within 4 weeks before RT initiation (T0), within 3 days before 6 weeks after the end of RT (T1), and 5 to 9 months after RT completion (T2). Associations between MHD and echocardiographically derived measures of cardiac function were assessed using generalized estimating equations to define the acute (T0 to T1) and subacute (T0 to T2) changes in cardiac function. Results The median estimates of MHD were 139 cGy (interquartile range, 99-249 cGy). In evaluating the acute changes in left ventricular ejection fraction (LVEF) from T0 to T1, and accounting for the time from RT, age, race, preexisting cardiovascular disease, and an interaction term with anthracycline or trastuzumab exposure and MHD, there was a modest decrease in LVEF of borderline significance (0.22%; 95% confidence interval [CI], –0.44% to 0.01%; P = .06) per 30-day interval for every 100 cGy increase of MHD. Similarly, there was a modest worsening in longitudinal strain (0.19%; 95% CI, –0.01% to 0.39%; P = .06) per 30-day interval for each 100 cGy increase in MHD. We did not find significant associations between MHD and changes in circumferential strain or diastolic function. Conclusions With modern radiation planning techniques, there are modest subclinical changes in measures of cardiac function in the short-term. Longer-term follow-up studies are needed to determine whether these early changes are associated with the development of overt cardiac disease.
