    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 Medicine
    This 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.

    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 Medicine
    This 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.

    Challenges and Opportunities in Developing an Oncology Clinical Trial Network in the United States Veterans Affairs Health Care System: The VA STARPORT Experience
    (MDPI, 2024-08-21) Solanki, Abhishek A.; Zheng, Kevin; Skipworth, Alicia N.; Robin, Lisa M.; Leparski, Ryan F.; Henry, Elizabeth; Rettig, Matthew; Salama, Joseph K.; Ritter, Timothy; Jones, Jeffrey; Quek, Marcus; Chang, Michael; Block, Alec M.; Welsh, James S.; Kumar, Aryavarta; Chao, Hann-Hsiang; Chen, Albert C.; Shapiro, Ronald; Bitting, Rhonda L.; Kwon, Robert; Stross, William; Puckett, Lindsay; Wong, Yu-Ning; Nickols, Nicholas G.; Carlson, Kimberly; VA STARPORT Investigators Group; Radiation Oncology, School of Medicine
    The United States Veterans Affairs (VA) Health Care System has a strong history of conducting impactful oncology randomized clinical trials (RCTs). We developed a phase II/III RCT to test the use of metastasis-directed therapy in Veterans with oligometastatic prostate cancer (OMPC)-the first VA RCT in OMPC that leverages novel imaging and advanced radiotherapy techniques. To accomplish this, we developed a clinical trial network to conduct the study. In this manuscript, we describe several challenges we encountered in study development/conduct and our strategies to address them, with the goal of helping investigators establish robust study networks to conduct clinical trials. In the study start-up, we encountered challenges in timely site activation, and leveraged project management to maximize efficiency. Additionally, there were several changes in the clinical paradigms in imaging and treatment that led to protocol amendments to ensure maximum equipoise, recruitment, and impact of the study. Specifically, we amended the trial to add de novo OMPC patients (from initially only recurrent OMPC) and expanded the study to allow up to 10 metastases (from initially five). Finally, in order to maintain local study team engagement, we developed initiatives to maximize collaboration and add value to the overall clinical program through study participation.

    Histology, Tumor Volume, and Radiation Dose Predict Outcomes in NSCLC Patients After Stereotactic Ablative Radiotherapy
    (Elsevier, 2018) Shiue, Kevin; Cerra-Franco, Alberto; Shapiro, Ronald; Estabrook, Neil; Mannina, Edward M.; Deig, Christopher R.; Althouse, Sandra; Liu, Sheng; Wan, Jun; Zang, Yong; Agrawal, Namita; Ioannides, Pericles; Liu, Yongmei; Zhang, Chen; DesRosiers, Colleen; Bartlett, Greg; Ewing, Marvene; Langer, Mark P.; Watson, Gordon; Zellars, Richard; Kong, Feng-Ming; Lautenschlaeger, Tim; Radiation Oncology, School of Medicine
    Introduction It remains unclear if histology should be independently considered when choosing stereotactic ablative body radiotherapy dose prescriptions for NSCLC. Methods The study population included 508 patients with 561 lesions between 2000 and 2016, of which 442 patients with 482 lesions had complete dosimetric information. Eligible patients had histologically or clinically diagnosed early-stage NSCLC and were treated with 3 to 5 fractions. The primary endpoint was in-field tumor control censored by either death or progression. Involved lobe control was also assessed. Results At 6.7 years median follow-up, 3-year in-field control, involved lobe control, overall survival, and progression-free survival rates were 88.1%, 80.0%, 49.4%, and 37.2%, respectively. Gross tumor volume (GTV) (hazard ratio [HR] = 1.01 per mL, p = 0.0044) and histology (p = 0.0225) were independently associated with involved lobe failure. GTV (HR = 1.013, p = 0.001) and GTV dose (cutoff of 110 Gy, biologically effective dose with α/β = 10 [BED10], HR = 2.380, p = 0.0084) were independently associated with in-field failure. For squamous cell carcinomas, lower prescription doses were associated with worse in-field control (12 Gy × 4 or 10 Gy × 5 versus 18 Gy or 20 Gy × 3: HR = 3.530, p = 0.0447, confirmed by propensity score matching) and was independent of GTV (HR = 1.014 per mL, 95% confidence interval: 1.005–1.022, p = 0.0012). For adenocarcinomas, there were no differences in in-field control observed using the above dose groupings (p = 0.12 and p = 0.31, respectively). Conclusions In the absence of level I data, GTV and histology should be considered to personalize radiation dose for stereotactic ablative body radiotherapy. We suggest lower prescription doses (i.e., 12 Gy × 4 or 10 G × 5) should be avoided for squamous cell carcinomas if normal tissue tolerances are met.
