研究目的:

主要目的为评估内镜下激光消融与EV+特瑞普利联合用于局部高危、非转移性UTUC 患者的疗效和安全性。主要疗效指标为无转换生存期(Conversion-Free Survival, CFS),即未转为RNU 的生存期。  

Objectives of Study:

The primary objective is to evaluate the efficacy and safety of endoscopic laser ablation combined with Enfortumab and Toripalimab for patients with localized high-risk, non-metastatic UTUC, with the primary efficacy endpoint being Conversion-Free Survival (CFS), defined as the survival period without conversion to radical nephroureterectomy (RNU).

Inclusion criteria

排除标准:

1、影像证实>=cT3 或N+或远处转移; 2、既往接受UTUC 系统性抗肿瘤治疗或放疗; 3、严重泌尿道解剖改变或输尿管狭窄导致无法行内镜操作; 4、麻醉、手术或药物禁忌,不能耐受EV 或特瑞普利; 5、活动性感染(HBV、HCV、HIV、结核等)或免疫抑制状态; 6、近2 年需系统免疫抑制治疗的自身免疫病; 7、重大心脑血管疾病或严重内科合并症影响安全性; 8、妊娠或哺乳期妇女; 9、5 年内活动性其他恶性肿瘤(除皮肤基底/鳞状细胞癌、宫颈原位癌等)。

Exclusion criteria:

1. Imaging‑confirmed >=cT3 stage, or N+, or distant metastasis; 2. Prior systemic anti‑tumor therapy or radiotherapy for UTUC; 3. Severe anatomical alterations of the urinary tract or ureteral stricture preventing endoscopic intervention; 4. Contraindications to anesthesia, surgery, or medication, including intolerance to Enfortumab or Toripalimab; 5. Active infection (e.g., HBV, HCV, HIV, tuberculosis) or immunosuppressed state; 6. Autoimmune disease requiring systemic immunosuppressive therapy within the past 2 years; 7. Major cardiovascular or cerebrovascular disease, or severe medical comorbidities compromising safety; 8. Pregnant or lactating women; 9. Active malignancy other than UTUC within the past 5 years (except for skin basal /squamous cell carcinoma, carcinoma in situ of the cervix, etc.).

干预措施:

接受EV 1.25mg/kg(D1,D8)+特瑞普利单抗240mg(D1)诱导治疗3周期(Q3W),之后行内镜肿瘤激光消融/电凝,术后EV继续6周期+特瑞普利单抗14周期。

干预措施代码:

Intervention:

Patients received 3 cycles (Q3W) of induction therapy with EV 1.25 mg/kg (D1, D8) plus Toripalimab 240 mg (D1), followed by endoscopic laser ablation/coagulation of the tumor. After surgery, EV was continued for 6 additional cycles, and Toripalimab was administered for a total of 14 cycles.
