Conditions
Summary
This study was a prospective, open-label, phase II randomised controlled clinical study, enrolling patients with primary oligometastatic uroepithelial carcinoma, oligometastasis was defined as ≤3 organs, and the number of metastatic lesions and size of metastases were not restricted to be able to satisfy the definition of full-coverage radiotherapy, with the exception of patients with brain metastases and more than 3 liver metastases. If regional lymph node recurrence was present, all positive regional lymph nodes were collectively referred to as one lesion. Non-regional lymph node metastases were counted as the number of metastases by lymph node subregion. Patients were divided into two groups according to whether they received radiotherapy or not: 1) systemic therapy group; 2) systemic therapy + radiotherapy group. Systemic drug therapy can be chosen from chemotherapy or immune checkpoint inhibitor therapy, or combination therapy.

Interventions
Systematic medical therapy is same as the systematic treatment group. SBRT radiotherapy or conventional fractionated radiotherapy can be used according to the extent and size of the metastatic foci. SBRT radiotherapy is preferred, and a higher dose should be given as far as possible when the normal tissues permit, with a preferred single dose of ≥5Gy.
The choice of first-line treatment is based on the guidelines, and may include chemotherapy or immune checkpoint inhibitors, or a combination of therapies. For patients who can tolerate cisplatin, chemotherapy is given with the gemcitabine-cisplatin regimen, as follows: gemcitabine 1000mg/m2 d1,8; cisplatin 70 mg/m2, avoiding light, intravenous drip d2; 3 weeks for 1 cycle. For intolerant patients, the gemcitabine-carboplatin regimen is given as follows: gemcitabine 1000 mg/m2 d1,8, IV, carboplatin (4.5×\[GFR+25\]) mg, IV, d1; 3 weeks as 1 cycle. Immune checkpoint inhibitors and targeted agents may be administered if the patient does not tolerate chemotherapy; either in combination with chemotherapy or directly as first line.
