About this trial

1. Study Type: Single-center, single-arm, prospective study. 2. Sample Size: 20 patients with high-risk endometrial cancer were enrolled. 3. Treatment Procedure:

The existing clinical oART (Online Adaptive Radiotherapy) workflow protocol for malignant tumors used in our department was applied.

Procedures included simulation, target volume delineation, radiotherapy planning, and treatment delivery.

External beam radiation therapy (EBRT) was delivered using moderate hypofractionation.

If indicated, brachytherapy was performed after the completion of EBRT. When combined with chemotherapy, radiotherapy could be administered during chemotherapy intervals or after completion of chemotherapy. 4. Study Endpoints:

Primary Endpoint: Incidence of acute toxicity. Secondary Endpoints: 3-year failure-free survival (FFS) rate, incidence of chronic toxicity, quality of life (QoL), treatment costs, etc.

Trial outcomes

Primary outcomes

1

Acute toxicity

Toxicities occurring \<90 days from radiotherapy initiation. Evaluated using CTCAE v5.0.

Time frame
<90 days after treatment initiation

Secondary outcomes

1

3-year failure-free survival

The time from treatment initiation until the occurrence of any treatment failure events.

Time frame
From date of surgery to the 3 years after treatment initiation
2

Chronic Toxicity

Toxicities occurring ≥90 days from radiotherapy initiation. Evaluated using the RTOG Late Morbidity Scoring Schema.

Time frame
≥90 days after treatment initiation
3

Quality of Life (EORTC QLQ-C30/EORTC QLQ-EN24)

EORTC QLQ-C30: This is a core quality of life questionnaire developed by the EORTC, applicable to all cancer patients. Scores are standardized to a 0-100 scale. For functional scales and the global quality of life scale, higher scores indicate better functioning or quality of life. For symptom scales/single items, higher scores indicate more severe symptoms or problems. EORTC QLQ-EN24: This is a module specifically designed to assess symptoms and quality of life unique to endometrial cancer patients. It serves as a supplementary module to the QLQ-C30 and cannot be analyzed independently. Scores are standardized to a 0-100 scale. For symptom items, higher scores indicate a greater symptom burden. For function/satisfaction items, higher scores indicate better function or satisfaction.

Time frame
From date of surgery to the 3 years after treatment initiation
4

Treatment Costs

Time frame
Through radiotherapy completion, an average of 1 month.
