Therefore, we used the lymph node metastasis and the PET SUVmean metabolic parameter to classify the PD-L1 positive rate of renal cancer lesions into a low-potential group (negative lymph node metastasis and SUVmean < 2.9), a moderate-potential group (negative lymph node metastasis and SUVmean ≥ 2.9, or positive lymph node metastasis and SUVmean < 2.9), and a high-potential group (positive lymph node metastasis and SUVmean ≥ 2.9). This evidence concerns the gene CD274 and renal carcinoma.
