研究目的:

本研究旨在评估螺旋断层放疗(TOMO)全腹盆腔低剂量照射联合同步加量技术,治疗伴有腹盆腔受累的放射敏感性骨与软组织肉瘤的安全性、可行性及初步疗效。 主要目的:评估治疗期间及治疗后 3 个月内,≥3 级急性非血液学毒性(胃肠道反应、肝肾功能损伤)的发生率。 次要目的:评估治疗计划成功率、治疗完成率;评估客观缓解率(ORR)、疾病控制率(DCR)、腹盆腔无进展生存期(abPFS)和总生存期(OS);评估患者生活质量(QoL)及靶区 / 危机器官剂量学参数与毒性的相关性。  

Objectives of Study:

This study aims to evaluate the safety, feasibility, and preliminary efficacy of helical tomotherapy (TOMO)-based low-dose whole abdominopelvic irradiation combined with simultaneous integrated boost (SIB) for radiosensitive bone and soft tissue sarcomas with abdominopelvic involvement. Primary objective: To assess the incidence of grade >=3 acute non-hematological toxicities (gastrointestinal reactions, hepatic/renal impairment) during treatment and within 3 months post-treatment. Secondary objectives: To evaluate treatment planning success rate and treatment completion rate; to assess objective response rate (ORR), disease control rate (DCR), abdominopelvic progression-free survival (abPFS), and overall survival (OS); to evaluate patient quality of life (QoL) and the correlation between target/organ-at-risk (OAR) dosimetric parameters and clinical toxicity.

药物成份或治疗方案详述:

采用螺旋断层放疗(TOMO)实施全腹盆腔照射,同步对可见残留病灶进行局部加量: 全腹盆腔基础剂量:≥14 岁患者予 15 Gy/10 次(1.5 Gy / 次,每日 1 次,每周 5 次);<14 岁患者予 12 Gy/10 次(1.2 Gy / 次,每日 1 次,每周 5 次)。 局部加量方案:优先采用同步加量(SIB),总剂量≥35 Gy/10 次(3.5 Gy / 次);若同步加量不符合危机器官剂量限制,则采用序贯加量,总剂量≥45 Gy/25 次(常规分割)或等效生物剂量的立体定向放疗。 计划要求:95% 的计划靶区(PTV)接受处方剂量,且所有危机器官(肝脏、肾脏、小肠、直肠等)剂量符合预设约束标准。 

Description for medicine or protocol of treatment in detail:

Helical tomotherapy (TOMO) is used for whole abdominopelvic irradiation with simultaneous integrated boost (SIB) to visible residual lesions: Whole abdominopelvic baseline dose: 15 Gy in 10 fractions (1.5 Gy/fraction, once daily, 5 days/week) for patients aged >=14 years; 12 Gy in 10 fractions (1.2 Gy/fraction, once daily, 5 days/week) for patients aged <14 years. Local boost strategy: Simultaneous integrated boost (SIB) is preferred, with a total dose of >=35 Gy in 10 fractions (3.5 Gy/fraction). If SIB violates organ-at-risk (OAR) constraints, sequential boost (>=45 Gy in 25 fractions with conventional fractionation) or equivalent biologically effective stereotactic body radiotherapy (SBRT) is used. Planning requirements: 95% of the planning target volume (PTV) receives the prescription dose, and all OARs (liver, kidneys, small intestine, rectum, etc.) meet predefined dose constraints.

1.组织学确诊的高放射敏感性骨与软组织肉瘤,包括促纤维增生性小圆细胞肿瘤(DSRCT)、尤文肉瘤、横纹肌肉瘤、黏液样脂肪肉瘤等。 2.影像学证实存在腹盆腔受累(转移、腹膜种植、恶性腹水、肿瘤破裂或术中污染,需行全腹盆腔放疗)。 3.年龄 6–39 岁(含儿童、青少年及年轻成人人群)。 4.Karnofsky 功能状态评分(KPS)≥60%。 5.预期生存期≥3 个月。 6.心肺肝肾功能可耐受放疗(如 FEV1≥50% 预计值,NYHA 心功能 I–II 级,肝肾功能正常或轻度异常)。 7.患者或法定监护人签署知情同意书。

Inclusion criteria

1. Histologically confirmed highly radiosensitive bone/soft tissue sarcoma, including desmoplastic small round cell tumor (DSRCT), Ewing sarcoma, rhabdomyosarcoma, myxoid liposarcoma, etc. 2. Imaging-confirmed abdominopelvic involvement (metastasis, peritoneal seeding, malignant ascites, tumor rupture, or intraoperative contamination requiring whole abdominopelvic radiotherapy). 3. Age 6–39 years (including pediatric, adolescent, and young adult populations). 4. Karnofsky Performance Status (KPS) >=60%. 5. Expected survival >=3 months. 6. Adequate cardiopulmonary, hepatic, and renal function to tolerate radiotherapy (e.g., FEV1 >=50% predicted, NYHA class I–II, normal or mildly abnormal organ function). 7. Informed consent signed by the patient or legal representative.

排除标准:

1.既往接受过腹盆腔放疗,存在无法接受的正常组织损伤风险。 2.存在活动性感染、未控制的糖尿病、严重高血压、不稳定型心绞痛、心力衰竭或其他严重合并症。 3.未控制的大量恶性腹水、完全性肠梗阻、活动性消化道出血。 4.严重肝肾功能不全(失代偿期肝硬化、慢性肾功能衰竭)。 5.妊娠或哺乳期女性。 6.存在精神或认知障碍,无法配合治疗。 7.同时参与另一项干预性临床研究。

Exclusion criteria:

1. Previous abdominal/pelvic radiotherapy with unacceptable risk of normal tissue injury. 2. Active infection, uncontrolled diabetes, severe hypertension, unstable angina, heart failure, or other severe comorbidities. 3. Uncontrolled massive malignant ascites, complete intestinal obstruction, or active gastrointestinal bleeding. 4. Severe hepatic/renal insufficiency (decompensated cirrhosis, chronic renal failure). 5. Pregnant or lactating women. 6. Mental or cognitive impairment, or inability to comply with treatment. 7. Concurrent participation in another interventional clinical study.
