Study design:

研究目的:

本研究拟评估在诱导治疗后达到部分缓解且残存病灶较为局限的晚期或者大肿块滤泡淋巴瘤患者患者,针对所有残余病灶实施受累部位放疗,并序贯常规的抗CD20维持治疗,能否相比单纯抗CD20单抗维持治疗提高完全缓解率、改善长期预后,并研究其安全性。  

Objectives of Study:

This study aims to evaluate, among patients with advanced-stage or bulky follicular lymphoma who achieve a partial response after induction therapy and have relatively localized residual disease, whether delivering involved-site radiotherapy (ISRT) to all residual lesions followed by standard anti-CD20 maintenance improves the complete response rate and long-term outcomes compared with anti-CD20 maintenance alone, and to assess its safety.

药物成份或治疗方案详述:

针对PET-CT评估残存病灶受累部位放疗(ISRT):3 Gy×4次(总剂量12 Gy) 

Description for medicine or protocol of treatment in detail:

Involved-site radiotherapy (ISRT) to PET-CT–defined residual disease: 3 Gy × 4 fractions (total dose, 12 Gy). 

纳入标准:

受试者在筛选时必须同时满足下列全部条件方可入组: 1.年龄与知情同意: 年龄≥18岁; 在详细了解试验目的、流程及潜在风险后,自愿签署书面知情同意书,并有能力遵从所有方案规定。 2.疾病确诊与分期组织学: 病理确诊为滤泡性淋巴瘤(WHO2022,1-3A级); 经过PET-CT分期为Ann-Arbor III-IV期(参考附录5),或II期且存在最长径≥5cm的大肿块病灶。 3.既往治疗与当前疾病状态: 仅接受过一线标准免疫化疗(R/G-CHOP、R/G-CVP、R/G-苯达莫司汀、R2等)6±2周期,未曾接受放疗、其他靶向/细胞治疗或其他系统抗肿瘤治疗; 诱导结束后4-12周内经中央盲态PET-CT评估为部分缓解(PR,Deauville4-5分); 残余代谢活跃病灶≤5个或局限于3个淋巴引流区; 至少1个可评估病灶,PET SUV高于肝脏平均值。 4.一般健康状况: 预期生存期≥24周; ECOG体能状态0-2分(参考附录6); 5.计划或已开始抗CD20维持1周期后1月以内。

Inclusion criteria

1. Age and informed consent Age >=18 years; After being fully informed of the study purpose, procedures, and potential risks, voluntarily signs a written informed consent form and is able to comply with all protocol requirements. 2. Diagnosis and staging Histologically confirmed follicular lymphoma (WHO 2022, grades 1–3A); PET–CT staging shows Ann Arbor stage III–IV (see Appendix 5), or stage II with bulky disease (longest diameter >=5 cm). 3. Prior therapy and current disease status Has received only one line of standard first-line immunochemotherapy (R/G-CHOP, R/G-CVP, R/G-bendamustine, R^2, etc.) for 6 +/- 2 cycles, with no prior radiotherapy, other targeted/cellular therapy, or other systemic anti-tumor therapy; Within 4–12 weeks after completion of induction, centrally blinded PET–CT assessment shows partial response (PR; Deauville score 4–5); Residual metabolically active lesions <=5, or confined to <=3 nodal drainage regions; At least one evaluable lesion with FDG uptake (SUV) higher than the mean liver SUV. 4. General condition Estimated life expectancy >=24 weeks; ECOG performance status 0–2 (see Appendix 6). 5. Maintenance plan Planned anti-CD20 maintenance therapy, or—if already initiated—enrollment within 1 month after the first cycle of maintenance.

排除标准:

符合以下标准之一者不可纳入本研究: 1.诱导治疗后仍存在骨髓受累; 2.需放疗部位既往曾接受放射治疗; 3.无法耐受放疗的情形: ANC<1.0×10?/L或血小板<50×10?/L,短期内无法恢复。 主要残余病灶解剖位置放疗剂量学无法满足本研究要求OAR约束,或合并症(严重肺间质纤维化)预计放疗将导致致命性毒性。 任何未控制的皮肤感染、开放性伤口或严重慢性溃疡处于拟照射区域。 其他经过放疗科医师评估无法耐受放疗的情形。 4.既往对利妥昔单抗或奥妥珠单抗出现过敏者,以及其他经内科医师评估无法耐受CD20巩固治疗者。 5.既往其他恶性肿瘤(除完全切除的原位癌、早期甲状腺癌外)。 6.妊娠、哺乳及生育规划妊娠期或哺乳期女性; 7.严重精神、神经系统或社会因素,研究者判定无法完成影像随访、e-PRO填报或放疗流程。

Exclusion criteria:

A candidate will be excluded if any of the following apply: 1. Persistent bone marrow involvement after induction therapy. 2. Prior radiotherapy to any site planned for irradiation in this study. 3. Inability to tolerate radiotherapy, including: ANC < 1.0 × 10^9/L or platelets < 50 × 10^9/L without expectation of short-term recovery; For the predominant residual lesion, the dosimetric/OAR constraints required by this study cannot be met, or comorbidities (e.g., severe interstitial pulmonary fibrosis) are expected to confer life-threatening toxicity with radiotherapy; Any uncontrolled skin infection, open wound, or severe chronic ulcer within the intended radiation field; Any other circumstance, in the radiation oncologist’s judgment, that precludes safe radiotherapy. 4. History of hypersensitivity to rituximab or obinutuzumab, or any other condition (per the medical oncologist’s assessment) that precludes CD20-directed maintenance therapy. 5. History of another malignancy, except for completely excised carcinoma in situ or completely resected early-stage thyroid cancer. 6. Pregnant or breastfeeding women, or women planning pregnancy during the study period. 7. Serious psychiatric, neurologic, or social factors that, in the investigator’s judgment, would prevent completion of imaging follow-up, e-PRO reporting, or the radiotherapy process.

本研究使用电子病例报告表(eCRF),通过经验证的电子数据采集(EDC)系统集中录入与管理。系统具备:账号/角色权限控制、审计追踪、程序化逻辑核查及质疑(Query)/更正流程、定期备份与加密导出。采集数据包括:人口学与病史、体格检查与生命体征、实验室指标、影像学资料(PET-CT/DICOM)、不良事件(按 NCI-CTCAE v5.0 分级)及患者报告结局(EORTC QLQ-C30)。关键影像由独立影像审评委员会(IRC)依据 Lugano 2014 标准进行盲态判读;严重不良事件(SAE)按要求即时上报,并由 IMC/DSMB 定期审阅。主要终点评估完成且数据核对/质疑清零后执行数据库锁定与归档。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data will be captured in eCRFs using a validated EDC system with role-based access, audit trail, programmed edit checks and a query/resolution workflow, encryption and regular backup. Collected data include demographics, medical history, physical exam and vital signs, laboratory tests, imaging (PET-CT/DICOM), adverse events (graded per NCI-CTCAE v5.0), and patient-reported outcomes (EORTC QLQ-C30). Key images are blinded-reviewed by the Independent Review Committee (IRC) per Lugano 2014. SAEs are reported immediately and reviewed periodically by IMC/DSMB. The database will be locked and archived after endpoint assessment and query reconciliation.
