研究目的:

1.主要目的 明确 TOMO-WLI-SIB/SBRT 策略的安全性,主要评估≥3 级急性放射性肺炎(CTCAE v5.0)的发生率。 确证 TOMO-WLI-SIB/SBRT 策略的有效性,主要评估患者的客观缓解率(ORR)、疾病控制率(DCR)及肺部无进展生存期(LPFS)。 2.次要目的 评估该 TOMO-WLI-SIB/SBRT 策略与靶向药物(如安罗替尼)或免疫检查点抑制剂(如 PD-1 抑制剂)联合应用时的安全性及协同抗肿瘤效应。 评估患者的总生存期(OS)及其他急性和晚期毒性反应的发生率。  

Objectives of Study:

1. Main Objectives To clarify the safety of the TOMO-WLI-SIB/SBRT strategy, mainly by evaluating the incidence of grade ≥ 3 acute radiation pneumonitis (CTCAE v5.0). To confirm the effectiveness of the TOMO-WLI-SIB/SBRT strategy, mainly by assessing the objective response rate (ORR), disease control rate (DCR), and lung progression-free survival (LPFS) of the patients. 2. Secondary Objectives To evaluate the safety and synergistic anti-tumor effect when this TOMO-WLI-SIB/SBRT strategy is combined with targeted drugs (such as anlotinib) or immune checkpoint inhibitors (such as PD-1 inhibitors). To assess the overall survival (OS) of the patients and the incidence of other acute and late toxic reactions.

Inclusion criteria

排除标准:

1. 既往接受过胸部放疗,经多学科团队(MDT)评估认为无法再安全接受本次全肺照射。 2. 存在活动性肺部感染、未经控制的大量胸腔积液或心包积液。 3. 患有严重的间质性肺病或肺功能严重受损(FEV1 < 预计值的 50%)。 4. 患有任何不稳定的系统性疾病,包括活动性感染、未控制的高血压、严重心律失常、心力衰竭(NYHA 心功能分级 III-IV 级)等。 5. 妊娠或哺乳期妇女。 6. 存在无法完成放疗的心理状态(如恐惧、焦虑),经研究者评估后,由精神科医生进一步判断确认。

Exclusion criteria:

1. Previously received chest radiotherapy, and the multidisciplinary team (MDT) assessment determined that it is no longer safe to undergo this full lung irradiation. 2. Present with active pulmonary infection, uncontrolled large pleural effusion or pericardial effusion. 3. Suffering from severe interstitial lung disease or severely impaired lung function (FEV1 < 50% of the predicted value). 4. Affected by any unstable systemic diseases, including active infection, uncontrolled hypertension, severe arrhythmia, heart failure (NYHA cardiac function classification III-IV grade), etc. 5. Pregnant or lactating women. 6. Having a psychological state that cannot complete radiotherapy, such as fear, anxiety (assessed by the researcher and confirmed by a psychiatrist).

干预措施:

采用螺旋断层调强放疗(TOMO)技术,对尤文肉瘤肺转移患者实施“时空分割”全肺照射。所有入组患者均接受该治疗。具体方案为:在全肺预防照射(12-15 Gy/10次)的基础上,对可见转移灶采用同步整合加量(SIB,至22-45 Gy/10次)或序贯立体定向放疗(SBRT,至22-45 Gy/5次)的模式进行推量,以期在提高肿瘤剂量的同时,最大限度地保护心脏、肺等重要器官。

干预措施代码:

Intervention:

The intervention of this study is: the implementation of "spatiotemporal fractionated" whole lung irradiation using helical tomotherapy (TOMO) for patients with pulmonary metastases from Ewing's sarcoma. All enrolled patients will receive this intervention. The specific regimen involves prophylactic whole lung irradiation (12-15 Gy/10 fractions) combined with either a simultaneous integrated boost (SIB, up to 22-45 Gy/10 fractions) or a sequential stereotactic body radiotherapy (SBRT, up to 22-45 Gy/5 fractions) to the visible metastases, aiming to escalate the tumor dose while maximally sparing critical organs such as the heart and lungs.
