Sim-Free Ethos: Feasibility of Same-Day Phantom-Based Adaptive Palliative Radiotherapy (SPRINT)
A Prospective, Phase II, Single-Arm Feasibility Study of Same-Day, Simulation-Free, Phantom-Based Online Adaptive Palliative Radiation
This study evaluates same-day, simulation-free adaptive palliative radiotherapy using an online adaptive radiotherapy platform. The study will assess whether image-guided adaptive radiotherapy can be safely and feasibly delivered within a single day for patients requiring palliative radiation treatment. Participants will receive either a single radiation fraction (8 to 20 Gy) or a hypofractionated regimen (25 to 40 Gy in 3 to 5 fractions), based on clinical requirements. The complete treatment workflow, including consultation, consent, adaptive planning, and treatment delivery, will be completed on the same day. The primary outcome is feasibility, defined as successful generation and delivery of a clinically acceptable adaptive treatment plan on the day of consultation. Secondary outcomes include workflow efficiency, acute toxicity, patient-reported outcomes, patient satisfaction, treatment tolerability, and dosimetric comparison between adaptive plans and standard institutional SBRT benchmarks. Approximately 40 participants will be enrolled and followed for up to 12 months.
The study hypothesizes same-day, simulation-free online adaptive palliative radiotherapy is feasible and safe, allowing timely delivery of clinically acceptable treatment plans without compromising treatment quality or patient experience.

实验性的：Same-Day Simulation-Free Adaptive Palliative Radiotherapy
|
Phantom-Based online adaptive radiotherapy delivered without a conventional simulation appointment. Treatment planning is generated using image-guided adaptive workflows on the day of consultation to enable same-day delivery of palliative radiotherapy. Radiation dose ranges from 8 to 20 Gy in a single fraction or 25 to 40 Gy delivered in 3 to 5 fractions, according to lesion location, target size, and normal tissue constraints. |

Feasibility of Same-Day Simulation-Free Adaptive Palliative Radiotherapy
大体时间：Baseline through 12 months
|
Defined as the proportion of participants for whom a clinically acceptable adaptive radiotherapy plan meeting predefined clinical goal variations is successfully generated and delivered on the same day as consultation. Feasibility will be expressed as a proportion with an exact 95% confidence interval. A success rate of ≥85% will be considered evidence that same-day adaptive radiotherapy is implementable in clinical practice. |

Workflow Duration
大体时间：Day of treatment
|
Time required to complete the simulation-free adaptive radiotherapy workflow, including consultation, consent, treatment planning, and treatment delivery. Workflow interruptions and causes of delays will also be documented. |
Day of treatment
|
|
Acute Treatment-Related Toxicity
大体时间：Baseline through 12 months
|
Incidence and severity of treatment-related adverse events assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 6.0. Toxicities will be summarized by grade, higher grades indicate worse outcomes |
Baseline through 12 months
|
|
Change in Pain Severity
大体时间：Baseline through 12 months
|
Pain will be assessed using the Brief Pain Inventory-Short Form (BPI-SF). Scales ranging from 0 to 10, where 0 indicates no pain/no interference and 10 indicates the worst pain imaginable or complete interference with daily activities. Higher scores indicate worse pain and greater pain-related interference. Changes in pain scores and analgesic use will be evaluated over time. |
Baseline through 12 months
|
|
Change in Quality of Life
大体时间：Baseline through 12 months
|
Quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Palliative Care (EORTC QLQ-C15-PAL). For the Global Quality of Life and Functional Scales, higher scores indicate better quality of life or functioning. For the Symptom Scales, higher scores indicate greater symptom burden and worse outcomes. |
Baseline through 12 months

|
Patient Satisfaction With Same-Day Adaptive Radiotherapy
大体时间：Day of treatment
|
Patient satisfaction will be assessed using a study-specific questionnaire evaluating treatment tolerability, comfort, communication, and overall experience with the same-day adaptive radiotherapy process. |
