Importance: There are limited studies assessing stage at diagnosis and risk of death among all 5 federally defined races in the US among adolescent and young adult (AYA) patients with cancer.

Objective: To identify racial disparities in stage at diagnosis and survival among AYA patients with cancer.

Design, Setting, And Participants: This retrospective cohort study used data from a US national hospital-based oncology database on AYA patients, aged 15 to 39 years, with the 10 deadliest cancers among AYA patients who received a diagnosis from January 1, 2004, to December 31, 2017, with 6 months or more of follow-up.

In Silico Comparison of Three Different Beam Arrangements for Intensity-Modulated Proton Therapy for Postoperative Whole Pelvic Irradiation of Prostate Cancer.

Proton therapy has been shown to provide dosimetric benefits in comparison with IMRT when treating prostate cancer with whole pelvis radiation; however, the optimal proton beam arrangement has yet to be established. The aim of this study was to evaluate three different intensity-modulated proton therapy (IMPT) beam arrangements when treating the prostate bed and pelvis in the postoperative setting. Twenty-three post-prostatectomy patients were planned using three different beam arrangements: two-field (IMPTB) (opposed laterals), three-field (IMPTB) (opposed laterals inferiorly matched to a posterior-anterior beam superiorly), and four-field (IMPTB) (opposed laterals inferiorly matched to two posterior oblique beams superiorly) arrangements.

Race and Ethnicity Representation in Phase 2/3 Oncology Clinical Trial Publications: A Systematic Review.

Importance: The five 1997 Office of Management and Budget races in the US include American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Other Pacific Islander, and White, with Hispanic ethnicity. Despite the Affordable Care Act mandating Office of Management and Budget-based collecting and reporting standards, race and ethnicity publishing in medical journals is inconsistent, despite being necessary to achieve health equity.

Objective: To quantify race and ethnicity reporting rates and calculate representation quotients (RQs) in published oncology clinical trials.

Prospective phase II trial of preoperative hypofractionated proton therapy for extremity and truncal soft tissue sarcoma: the PRONTO study rationale and design.

Background: Oncologic surgical resection is the standard of care for extremity and truncal soft tissue sarcoma (STS), often accompanied by the addition of pre- or postoperative radiation therapy (RT). Preoperative RT may decrease the risk of joint stiffness and fibrosis at the cost of higher rates of wound complications. Hypofractionated, preoperative RT has been shown to provide acceptable outcomes in prospective trials.

Effects of adherence to treatment for repositioning therapy, physical therapy, and cranial remolding orthoses in infants with cranial deformation.

Deformational head shapes are most often treated through repositioning therapy (RT) and/or cranial remolding orthotic (CRO) treatment. However, there is conflicting evidence about the effectiveness of each method, and treatment compliance is suspected to affect treatment effectiveness. This study examines participant adherence with these treatment methods and explores if cranial correction is related to compliance.

Parenting dimensions and views on adolescent decision making in health care: A cross-national study of Belgian and Dutch parents.

Background: The aim of this study was to investigate the link between parenting and parents' perspectives on health-related decision making for adolescents. During adolescence, there is a gradual increase in responsibility and autonomy, which influences parenting behavior and child development. Understanding how parenting is associated with parents' views on medical decision making is crucial in the context of the parent-child-physician triad.

Pilot Study Assessing Student Interest in Combined Residency Training Pathways With Radiation Oncology.

Purpose: Most medical students have limited exposure to radiation oncology (RO) before deciding which specialty to choose for residency. This may limit the number and diversity of RO applicants. The purpose of this study was to determine students' views on a combined pathway program of RO with internal medicine (IM), as well as other related medical specialties, as a potential means of overcoming barriers to interest in RO and the early decision point to solo training in a highly specialized field.

Gender and the Receipt of the Association of Residents in Radiation Oncology Educator of the Year Award.

Purpose: We hypothesized that there may be a gender disparity in the receipt of the Association of Residents in Radiation Oncology (ARRO) Educator of the Year Award and sought to elucidate factors that contribute to differences in award receipt.

Methods And Materials: Using a database provided by the American Society for Radiation Oncology, award recipients were identified from 2010 to 2022. Publicly available websites were accessed to obtain data regarding gender, years since residency graduation, percentage of female faculty, size of residency program, and program director designation.

Case-Matched Outcomes of Proton Beam and Intensity-Modulated Radiation Therapy for Localized Prostate Cancer.

Purpose: Although both intensity-modulated radiation therapy (IMRT) and proton beam therapy (PBT) offer effective long-term disease control for localized prostate cancer (PCa), there are limited data directly comparing the 2 modalities.

Methods: The data from 334 patients treated with conventionally fractionated (79.2 GyRBE in 44 fractions) PBT or IMRT were retrospectively analyzed.

Deleterious effects of intradialytic meals' suppression during the COVID pandemic.

Background&aims: Patients with end-stage renal failure on chronic hemodialysis present an important risk of malnutrition, which is associated with a significant risk of morbidity and mortality. Meals during the dialysis session are important for maintaining the nutritional status of dialysis patients but represent a risk for intradialytic hypotension. During the COVID-19 pandemic, several dialysis centers stopped providing meals during the dialysis session as a protective measure.

Dose evaluation of inter- and intra-fraction prostate motion in extremely hypofractionated intensity-modulated proton therapy for prostate cancer.

Inter- and intra-fractional prostate motion can deteriorate the dose distribution in extremely hypofractionated intensity-modulated proton therapy. We used verification CTs and prostate motion data calculated from 1024 intra-fractional prostate motion records to develop a voxel-wise based 4-dimensional method, which had a time resolution of 1 s, to assess the dose impact of prostate motion. An example of 100 fractional simulations revealed that motion had minimal impact on planning dose, the accumulated dose in 95 % of the scenarios fulfilled the clinical goals for target coverage (D95 > 37.

Comparative In Silico Analysis of Ultra-Hypofractionated Intensity-Modulated Photon Radiotherapy (IMRT) Versus Intensity-Modulated Proton Therapy (IMPT) in the Pre-Operative Treatment of Retroperitoneal Sarcoma.

Background: While pre-operative radiation did not improve abdominal recurrence-free survival for retroperitoneal sarcoma (RPS) in the randomized STRASS trial, it did reduce rates of local recurrence. However, the risk of toxicity was substantial and the time to surgery was prolonged. A combination of hypofractionation and proton therapy may reduce delays from the initiation of radiation to surgery and limit the dose to surrounding organs at risk (OARs).

In silico comparison of whole pelvis intensity-modulated photon versus proton therapy for the postoperative management of prostate cancer.

Background: Limited data exist comparing intensity-modulated photon (IMRT) and proton (IMPT) radiation therapy when treating the prostate bed and pelvic lymph nodes in the postoperative setting for prostate cancer. The aim of this study was to evaluate dosimetric differences between IMRT and IMPT when treating with whole pelvis radiation therapy (WPRT) postoperatively.

Materials And Methods: IMRT and IMPT plans were generated for 10 post-prostatectomy patients treated between July and August 2020.
