Brief Summary:
This is a prospective cohort study to analyse the safety and efficacy of postoperative adjuvant radiotherapy combined with immunotherapy versus surgery alone group of UTUC patients with T3-4 stages or lymph nodes metastasis(N+) status.
Detailed Description:
This study is a prospective cohort study.
1. Observation group: patients in the observation group were T3-4,N+ pyeloureteral cancer patients who did not tolerate chemotherapy or refused chemotherapy after radical surgery. No treatment will be given after surgery, and regular review will be conducted.
2. Postoperative immunotherapy+radiotherapy group:
Adjuvant immunotherapy: the immunotherapy drug choice is tirilizumab, which has been recommended in metastatic uroepithelial cancer in China. Tirelizumab 200mg Q3w; the duration of immunotherapy is recommended to be used for at least 1 year.
Adjuvant radiotherapy can be given concurrently or sequentially with adjuvant immunotherapy; it is recommended that radiotherapy can be started within 4-6 weeks after surgery. Rotational intensity-modulated radiotherapy (VMAT), daily image-guided radiotherapy (Daily IGRT) technique is used.
Irradiation range:
Renal pelvis and upper ureter: ipsilateral renal fossa, para-abdominal aorta (including upper ureteral alignment area), common iliac lymph node area; Middle and lower ureteral carcinoma: parabasal abdominal aorta (renal hilar vessels and following levels), common iliac lymph node area (right side needs to include paraventricular lymph node area) + internal and external iliac lymph node area + middle and lower ureteral alignment area, entrance of the ureteral bladder.
Radiotherapy dose: 45-50Gy/25f/5w, 62.5Gy/25f/5w regimen was given to suspected metastatic lymph nodes visible on imaging. Ensure that normal tissue is within the dose limits.
Note: The right tumour para-abdominal aortic lymph node drainage area needs to include: para vena cava + intervening vena cava + left para-abdominal aorta Left tumour para-abdominal lymph node drainage area needs to include: intervening vena cava + left para-abdominal aorta
