Abstract
PURPOSE Novel techniques and advances in radiation therapy (RT) have been explored to treat testicular seminoma, a highly radiosensitive and curable histology. We evaluated the historical and current indications for radiation therapy (RT) in testicular seminoma. METHODS A narrative literature review was performed. Studies of RT for testicular seminoma were included. Additionally, recent trials testing the use of combination or surgical therapies for clinical stage (CS) II were included. Search parameters included radiation therapy, testicular seminoma, surgery, and chemoradiation. Parameters and outcomes assessed were progression-free survival (PFS), overall survival (OS), acute toxicities, long-term sequelae, and rates of secondary malignancies. RESULTS Practice defining and changing studies in the use or omission of radiation therapy for testicular seminoma were identified along with resultant changes in National Comprehensive Cancer Network (NCCN) and European guidelines. Recent trials in combined chemoradiation and upfront surgical approaches to CS II disease were reviewed. CONCLUSION RT has historically been used as adjuvant treatment for CS I disease and is highly effective at treating CS II (A/B) testicular seminoma. The drive to maintain therapeutic efficacy and reduce acute and long-term side effects, namely secondary malignancies, is being tested using new radiation technologies, combined modality therapy in the form of chemoradiation and with upfront surgical approaches. Also, as guidelines now "strongly prefer" surveillance instead of adjuvant RT for CS I disease, the current CS II population comprises patients presenting with CS II disease ("de novo") and those who present with CSII after relapsing post orchiectomy for CS I ("relapsed"). Emerging evidence suggests that these two groups have different outcomes with respect to RT and chemoradiation. Consequently, future trials may need to sub-stratify according to these groups.

Abstract
Radiation therapy plays a crucial role for the management of genitourinary malignancies, with technological advancements that have led to improvements in outcomes and decrease in treatment toxicities. However, better risk-stratification and identification of patients for appropriate treatments is necessary. Recent advancements in imaging and novel genomic techniques can provide additional individualized tumor and patient information to further inform and guide treatment decisions for genitourinary cancer patients. In addition, the development and use of targeted molecular therapies based on tumor biology can result in individualized treatment recommendations. In this review, we discuss the advances in precision oncology techniques along with current applications for personalized genitourinary cancer management. We also highlight the opportunities and challenges when applying precision medicine principles to the field of radiation oncology. The identification, development and validation of biomarkers has the potential to personalize radiation therapy for genitourinary malignancies so that we may improve treatment outcomes, decrease radiation-specific toxicities, and lead to better long-term quality of life for GU cancer survivors.

Abstract
Purpose To determine the clinical outcomes and toxicities of proton beam therapy (PBT) versus 3D-conformal photon radiation therapy (XRT) in patients with testicular seminoma. Materials and Methods This observational study evaluated consecutive patients with testicular seminoma who were treated with inguinal orchiectomy and radiation therapy at a single, tertiary, high-volume center in 2008-19. Acute toxicity was scored with the Common Terminology Criteria for Adverse Events V 4.0. Organs at risk were contoured retrospectively by 2 investigators. Recurrences and secondary malignancies were based on routine follow-up imaging, either computed tomography or magnetic resonance imaging. Results Fifty-five patients were treated with radiation therapy, 11 in the PBT-arm and 44 in the XRT-arm, with a median follow-up interval of 61 months (interquartile range [IQR]: 32-79 months). Acute treatment-related diarrhea, grade 1 to 2, was more common among XRT-treated patients (0% vs 29.5%, P = .039), and dermatitis, grade 1, was more likely among PBT-treated patients (27.3% vs 2.3%, P = .004). Dosimetrically, PBT-treated patients, relative to XRT-treated patients, had lower dose to organs at risk including the kidney, bladder, femoral head, spinal cord, bowel, pancreas, and stomach. The 5-year overall survival rate was 100% and disease-free survival rate was 96.4% for all patients. Two patients, all in the XRT-arm, had disease recurrence: 1 in the pelvis and 1 in the lung. Three patients, all in the XRT-arm, were diagnosed with a secondary malignancy: 1 in-field pancreaticoblastoma, 1 in-field colon adenocarcinoma, and a stage IV T-cell lymphoma. Conclusion Proton beam therapy for testicular seminoma resulted in excellent clinical outcomes and was associated with lower rates of acute diarrhea but higher rates of acute dermatitis. Proton beam therapy resulted in no in-field secondary malignancies and a more favorable dosimetric profile for organs at risk relative to XRT. Reduced dose to organs at risk, such as the kidneys, may result in long-term improvement in function.

Abstract
INTRODUCTION Previous studies have investigated the anatomical distribution of para-aortic lymph nodes (PAN) in patients with cervical cancer. However, an atlas for accurate clinical target volume (CTV) delineation has yet to be defined. The purpose of this study was to design and verify a computerized tomography (CT) atlas to provide guidance for contouring the PAN CTV in patients with cervical cancer. MATERIALS AND METHODS This prospective study included 21 cervical cancer patients (design cohort) with 39 pathological PAN identified on (18)F-FDG PET-CT. PAN [left lateral para-aortic (LLPA), aorto-caval (AC), right para-caval (RPC) nodes] were delineated on CT simulation scans. Measurements were taken from the volumetric centre of the nodes to the edge of aorta and inferior vena-cava (IVC). Initially the aorta and IVC were expanded by the mean distance to the lymph node centre to create a CTV. Expansion margins were then increased asymmetrically until the CTV resulted in a clinically acceptable number of PAN included. The CTV was validated on a further 10 patients (validation cohort) with 29 PAN. A detailed contouring guide and accompanying visual atlas for elective PAN CTV delineation was created based on the validated margins. RESULTS For the design cohort (n = 21 patients, 39 PAN), the mean distance from the centre of the node to the aorta was 8 mm (range 4-17) for both LLPA (range 4-17) and AC (range 4-15) regions. Mean distance from the IVC to the centre of the nodes was 5 mm (range 4-6) in the RPC region and 6 mm (range 3-15) in the AC region. No PAN was superior to the T12-L1 interspace or the left renal vein or inferior to the L5-S1 interspace. For validation cohort (n = 10 patients, 29 PAN), mean distance from centre of the node to the aorta was 9 mm (range 5-15) in the LLPA region, 7 mm (range 6.5-14) in the AC region. Mean distance from the ICV to the centre of the nodes was 3 mm (range 2.5-4) in the RPC region and 5 mm (range 3-10) in the AC region. A CTV expansion from the aorta of 10 mm circumferentially and 15 mm laterally, and from the IVC of 8 mm anteromedially and 6 mm posterolaterally resulted in coverage of 97% (38/39) of PAN in the design cohort. On prospective validation, the described CTV included 97% (28/29) of PAN in the validation cohort. CONCLUSION We propose the following PAN CTV; expansion from aorta of 10 mm circumferentially except 15 mm laterally, expansion from the IVC of 8 mm anteromedial and 6 mm posterolaterally. The suggested CTV includes 97% (28/29) PAN in a validated patient cohort. A detailed guide and accompanying visual atlas is provided to aid delineation of the PAN CTV in patients with cervical cancer.

Abstract
PURPOSE/OBJECTIVE Disease-specific survival for testicular seminoma approaches 100%, even for those with node-positive disease. We sought to describe modern practice patterns, survival outcomes, and factors associated with postoperative therapy for patients with clinical stage (CS) IIA/B disease. METHODS AND MATERIALS Data on patients diagnosed with CS IIA/B seminoma from 1998 to 2012 were extracted from the National Cancer Data Base. Demographic, clinical, treatment, and payer characteristics were evaluated using multivariate regression to identify factors associated with receipt of chemotherapy or radiation therapy (RT) within 6 months of orchiectomy. Five-year Kaplan-Meier overall survival (OS) by CS and treatment was calculated. A Cox proportional hazards regression for 5-year OS was performed. RESULTS A total of 1885 patients were included; 38.5% received chemotherapy and 61.5% received RT. On multivariate analysis, factors associated with receipt of postorchiectomy RT rather than chemotherapy included CS IIA (odds ratio [OR], 3.04; P < .01) and community treatment setting (OR, 1.81-2.76; P < .01). Reduced likelihood of receiving RT was associated with Medicaid insurance (OR, 0.50; P < .01), more recent year of diagnosis (continuous OR, 0.93; P < .01), and primary pathologic tumor 3/4 stage (OR, 0.47; P < .01). On multivariate Cox regression, decreased 5-year OS was associated with receipt of chemotherapy in CS IIA patients (hazard ratio, 13.33; P < .01) but not in CS IIB patients (hazard ratio, 1.39; P = .45). For CS IIA, 5-year OS was 99.4% for orchiectomy and RT versus 91.2% for orchiectomy and chemotherapy (log-rank P < .01). For CS IIB, 5-year OS was 96.1% for orchiectomy and RT versus 92.8% for orchiectomy and chemotherapy (log-rank P = .08). CONCLUSIONS Consistent with national guideline recommendations, our analysis supports preferred status for RT in CS IIA. In addition, these data also support use of RT for CS IIB. CS, treatment year, primary pathologic tumor stage, insurance, and facility type were associated with type of postoperative therapy. Longer follow-up to account for potential late effects of treatment is needed.
