Instant plan quality prediction on transrectal ultrasound for high-dose-rate prostate brachytherapy.

Purpose: We investigated the feasibility of AI to provide an instant feedback of the potential plan quality based on live needle placement, and before planning is initiated.

Materials And Methods: We utilized YOLOv8 to perform automatic organ segmentation and needle detection on 2D transrectal ultrasound images. The segmentation and detection results for each patient were then fed into a plan quality prediction model based on ResNet101.

Hypofractionated Radiation Therapy (Hypo-RT) for the Treatment of Localized Bladder Cancer.

Background: Various radiotherapeutic regimens are used in the treatment of bladder cancer.

Objective: We aimed to evaluate early toxicity and outcomes associated with hypofractionated radiation therapy (Hypo-RT), 55Gy in 20 fractions.

Material And Methods: We identified 40 patients who received definitive Hypo-RT for localized bladder cancer.

Patient Safety and Satisfaction With Fully Remote Management of Radiation Oncology Care.

Importance: Patients of Memorial Sloan Kettering Cancer Center in New York, New York, are now offered a choice of either in-person or remote telehealth visits for radiation oncology care. However, safety and satisfaction among patients receiving treatment with fully remote physician management is unclear.

Objective: To analyze patient safety and satisfaction, financial implications, and environmental consequences associated with fully remote management among a cohort of patients treated with radiotherapy.

Long-term Outcomes from a Phase 1 Dose Escalation Study Using Stereotactic Body Radiotherapy for Patients with Low- or Intermediate-risk Prostate Cancer.

Background: Ultrahypofractionated stereotactic body radiation therapy (SBRT) has become a standard treatment intervention for localized prostate cancer.

Objective: To report final long-term tumor control outcomes and late gastrointestinal (GI) and genitourinary (GU) toxicities from a single-center phase 1 dose escalation study using SBRT for patients with low- or intermediate-risk prostate cancer.

Design, Setting And Participants: Between 2009 and 2012, 136 patients were enrolled and treated.

Quality Metric to Assess Adequacy of Hydrogel Rectal Spacer Placement for Prostate Radiation Therapy and Association of Metric Score With Rectal Toxicity Outcomes.

Purpose: Although hydrogel spacer placement (HSP) minimizes rectal dose during prostate cancer radiation therapy, its potential benefit for modulating rectal toxicity could depend on the achieved prostate-rectal separation. We therefore developed a quality metric associated with rectal dose reduction and late rectal toxicity among patients treated with prostate stereotactic body radiation therapy (SBRT).

Methods And Materials: A quality metric consisting of prostate-rectal interspace measurements from axial T2-weighted magnetic resonance imaging simulation images was applied to 42 men enrolled in a multi-institutional phase 2 study using HSP with prostate SBRT (45 Gy in 5 fractions).
