Abstract
BACKGROUND Approximately 20-40% of patients with prostate cancer (PC) who undergo radical prostatectomy (RP) experience relapse, with the majority of these cases developing pelvic lymph node (LN) metastases. Taking new data from the prostate-specific membrane antigen (PSMA) positron emission tomography (PET) era into account, the Radiation Therapy Oncology Group (RTOG) 2009 contouring guideline for the pelvic LNs from 2009 was updated by the NRG Oncology group in 2020 (NRG 2020). OBJECTIVE To evaluate and validate the updated NRG 2020 guideline with our established LN atlas. DESIGN, SETTING, AND PARTICIPANTS We screened 1653 PSMA PET/computed tomography (CT) data sets for patients with biochemical relapse who underwent a PET scan between November 2012 and November 2017. After screening, we developed an LN atlas using data from 233 patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We evaluated LN overlap (OL) with the RTOG 2009 and NRG 2020 contouring guidelines. OL was defined as within (>90%), partly within (10-90%), or outside (<10%). RESULTS AND LIMITATIONS In comparison to the RTOG 2009 guideline, 403 (52%), 134 (17%), and 241 (31%) of the LNs were not, were partly, or were fully covered within the overall group, respectively. By contrast, using the NRG 2020 guideline, 302 (39%), 190 (24%), and 286 (37%) of the LNs were not, were partly, or were fully covered, respectively (p < 0.001). Limitations include the retrospective design with missing data and no histopathological confirmation of the PET results. CONCLUSIONS The updated NRG 2020 contouring guideline improves coverage of the pelvic LNs in patients undergoing salvage radiation therapy. However, PET/CT should be considered whenever possible to ensure coverage of untypical LN spread. PATIENT SUMMARY We compared the 2009 and 2020 guidelines on the radiation area for the pelvis for patients with recurrent prostate cancer that has spread to lymph nodes. The newer guideline provides better coverage of pelvic lymph nodes than the older one and is useful in planning radiation therapy. However, a scan of the pelvis using the newest technique should be considered for individual patients to ensure coverage of untypical lymph nodes.

Abstract
To evaluate the relative efficacy of topical steroids in preventing radiation dermatitis (RD). Multiple databases including Medline, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), China Biological Medicine (SinoMed), and Wanfang Database were searched for randomized controlled trials (RCTs) of RD prevention in patients with cancer from inception to November 26, 2021, followed by an update on June 1, 2021. Six RCTs evaluating the efficacy of topical steroids in preventing RD in a total of 661 patients with cancer were included. RD incidence was lower with topical steroids compared with placebo at week 3 (relative risk [RR] = 0.68, 95% confidence interval [CI]: 0.31-1.50) and at radiation therapy (RT) completion (RR = 0.97, 95% CI: 0.93-1.00). Topical steroids demonstrated a less risk of developing dermatitis of Radiation Therapy Oncology Group (RTOG) grades 2 and 3 at the completion of RT (RR = 0.66, 95% CI: 0.55-0.80 and RR = 0.54, 95% CI: 0.38-0.77, respectively). However, topical steroids did not reduce RTOG grades 1 and 2 dermatitis at week 3(RR = 0.73, 95% CI: 0.45-1.14 and RR = 0.66, 95% CI: 0.27-1.60, respectively). Notably, the use of topical steroids did not decrease RD incidence when patients received combined chemotherapy (RR = 0.60, 95% CI: 0.42-0.86), and an obvious reduction in the incidence of RD at RT completion was found when patients used the topical steroids twice-daily (RR = 0.66, 95% CI: 0.47-0.93, P = 0.02). Topical steroids reduced RD incidence in patients receiving RT. Thus, twice-daily topical steroids may be recommended for patients at the beginning of RT.

Abstract
BACKGROUND No risk-stratification strategies exist for patients with recurrent oropharyngeal cancer (OPC). METHODS Retrospective analysis using data from prospective NRG Oncology clinical trials RTOG 0129 and 0522. Eligibility criteria included known p16 status and smoking history, and locoregional/distant recurrence. Overall survival (OS) was measured from date of recurrence. Recursive partitioning analysis was performed to produce mutually exclusive risk groups. RESULTS Hundred and fifty-four patients were included with median follow-up after recurrence of 3.9 years (range 0.04-9.0). The most important factors influencing survival were p16 status and type of recurrence, followed by surgical salvage and smoking history (≤20 vs. >20 pack-years). Three significantly different risk groups were identified. Patients in the low-, intermediate-, and high-risk groups had 2-year OS after recurrence of 81.1% (95%CI 68.5-93.7), 50.2% (95%CI 36.0-64.5), and 20.8% (95%CI 10.5-31.1), respectively. CONCLUSION Patient and tumor characteristics may be used to stratify patients into risk groups at the time of OPC recurrence.

Abstract
Aim: The aim of this study is to evaluate the effect of honey on clinically scoring grades of oral mucositis. Materials and Methods: This interventional study was carried out in Radiation Oncology Department of Mayo Hospital, Lahore. In this study, 82 patients of both genders, of head and neck cancer, planned for radiotherapy, were divided into two groups by random sampling numbers. Patients in both groups were treated with a total dose of 60–78 Grays in 4–6 weeks. In treatment group, patients were instructed to take 20 mL of honey. In control group, they were advised to rinse with 0.9% of saline. Patients were evaluated every week to assess the grades of oral mucositis up to 6 weeks. The assessment tool was Radiation Therapy Oncology Group Grading System. The statistical analysis was done by Chi-square test. Results: In honey-treated group, the proportion of mucositis (Grades 3 and 4) was lower and statistically significant as compared to control group at the end of 6 weeks of radiation. Conclusion: This study showed that oral intake of honey during radiotherapy is valuable in the reduction of severity of oral mucositis.

Abstract
PURPOSE The purpose of this guideline is to provide a clinical framework for the use of radiotherapy after radical prostatectomy as adjuvant or salvage therapy. MATERIALS AND METHODS A systematic literature review using the PubMed®, Embase, and Cochrane databases was conducted to identify peer-reviewed publications relevant to the use of radiotherapy after prostatectomy. The review yielded 294 articles; these publications were used to create the evidence-based guideline statements. Additional guidance is provided as Clinical Principles when insufficient evidence existed. RESULTS Guideline statements are provided for patient counseling, the use of radiotherapy in the adjuvant and salvage contexts, defining biochemical recurrence, and conducting a re-staging evaluation. CONCLUSIONS Physicians should offer adjuvant radiotherapy to patients with adverse pathologic findings at prostatectomy (i.e., seminal vesicle invasion, positive surgical margins, extraprostatic extension) and should offer salvage radiotherapy to patients with prostatic specific antigen or local recurrence after prostatectomy in whom there is no evidence of distant metastatic disease. The offer of radiotherapy should be made in the context of a thoughtful discussion of possible short- and long-term side effects of radiotherapy as well as the potential benefits of preventing recurrence. The decision to administer radiotherapy should be made by the patient and the multi-disciplinary treatment team with full consideration of the patient's history, values, preferences, quality of life, and functional status. Please visit the ASTRO and AUA websites (http://www.redjournal.org/webfiles/images/journals/rob/RAP%20Guideline.pdf and http://www.auanet.org/education/guidelines/radiation-after-prostatectomy.cfm) to view this guideline in its entirety, including the full literature review.

Abstract
BACKGROUND Previously published randomized evidence did not report a survival advantage for patients diagnosed with grade IV glioma who were treated with stereotactic radiosurgery followed by external beam radiation therapy and chemotherapy when compared to patients treated with external beam radiation therapy and chemotherapy alone. In recent years, gamma knife radiosurgery has become increasingly popular as a salvage treatment modality for patients diagnosed with recurrent high-grade glioma. The purpose of this article is to review the efficacy of gamma knife radiosurgery for patients who suffer from this malignancy. METHODS Retrospective, prospective, and randomized clinical studies published between the years 2000 and 2012 analyzing gamma knife radiosurgery for patients with high-grade glioma were reviewed. RESULTS After assessing patient age, Karnofsky performance status, tumor histology, and extent of resection, gamma knife radiosurgery is a viable, minimally invasive treatment option for patients diagnosed with recurrent high-grade glioma. The available prospective and retrospective evidence suggests that gamma knife radiosurgery provides patients with a high local tumor control rate and a median survival after tumor recurrence ranging from 13 to 26 months. Gamma knife radiosurgery followed by chemotherapy for recurrent high-grade glioma may provide select patients with increased levels of survival. However, further investigation into this matter is needed due to the limited number of published reports. Additional clinical research is also needed to analyze the efficacy and radiation-related toxicities of fractionated gamma knife radiosurgery due to its potential to limit treatment-associated morbidity. CONCLUSIONS Gamma knife radiosurgery is a safe and effective treatment option for select patients diagnosed with recurrent high-grade glioma. Although treatment outcomes have improved, further evidence in the form of phase III randomized trials is needed to assess the durability of treating patients in specific clinical situations.
