Actual date on which the first participant was enrolled.

This study aims to compare two types of radiation therapy for treating soft tissue sarcoma, a type of cancer that forms in the soft tissues of the body. Spatially Fractionated Radiation Therapy (SFRT) and Conventional Radiation Therapy (CRT) are being tested to see which is more effective and safe for patients with tumors larger than 5 cm. Soft tissue sarcoma is known to be less responsive to traditional radiation, so this study could help find better ways to control the tumor and improve patients' outcomes. The study is important because it might lead to improved treatment strategies for this type of cancer and possibly other cancers that are hard to treat with radiation. In the study, a total of 106 patients will be randomly assigned to receive either SFRT or CRT. SFRT involves giving radiation in a more targeted way, with additional high-dose treatments, while CRT uses a standard approach. The effectiveness of the treatments will be assessed by looking at how well the tumors respond over 12 months, and other factors like how long patients live without their cancer getting worse. Safety is also an important part of the study, with regular checks for side effects during and after treatment. The results will help determine if SFRT can offer better outcomes than CRT, which would be a significant advancement in treating this cancer.

106 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Criteria

Inclusion Criteria: * 1\. Age 18-70 years, irrespective of gender. 2. Pathologically or clinically confirmed diagnosis of soft tissue sarcoma. 3. Minimum tumor diameter ≥5 cm. 4. Receiving systemic treatment as per multidisciplinary team (MDT) recommendations. 5\. Measurable lesion (per RECIST 1.1/Choi criteria: longest diameter \>1.5 cm, or \>1 cm with two measurable perpendicular diameters). 6\. ECOG performance status ≤2. 7. Expected survival ≥3 months. 8. Normal liver, kidney, lung, and cardiac function, with tolerance for treatment. 9\. Patients of childbearing potential agree to use reliable contraception during treatment and for one year thereafter. 10\. Voluntary provision of signed informed consent. Exclusion Criteria: * (1) Patients with a second primary malignancy. (2) Diagnosis of aggressive fibromatosis or rhabdomyosarcoma. (3) Prior radiotherapy to the target lesion. (4) Tumor unsuitable for radiotherapy. (5) Severe liver, kidney, lung, or cardiac dysfunction, precluding tolerance to systemic therapy or radiotherapy. (6) Other severe medical conditions that may impact the study (e.g., uncontrolled diabetes, gastric ulcers, or other serious cardiopulmonary diseases). (7) Severe or uncontrolled infections, or active autoimmune diseases. (8) Clinically evident central nervous system dysfunction. (9) Pregnant or lactating women, or women of childbearing potential not using contraception. (10) Other conditions deemed unsuitable for participation by the investigator.

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
SFRT builds on CRT, administered at 3.0 Gy per fraction for 15-20 fractions, with the addition of weekly high-dose vertices of 8-15 Gy per fraction for 3-4 fractions. It utilizes Intensity-Modulated Radiation Therapy (IMRT), Intensity-Modulated Proton Therapy (IMPT), or Volumetric Modulated Arc Therapy (VMAT) to create a grid-like pattern of alternating high- and low-dose regions.

Group II

Active Comparator
CRT is delivered at 3.0 Gy per fraction for a total of 15-20 fractions, utilizing Intensity-Modulated Radiation Therapy (IMRT) or Intensity-Modulated Proton Therapy (IMPT) techniques, ensuring a target volume dose coverage of at least 90%.
