Recurrence and metastasis are mainly related to the early and late stage of the disease. Recurrence means that there is residue after the first treatment, which leads to tumor recurrence in the later stage. Although the treatment effect of renal clear cell carcinoma is relatively good, some patients are often in the middle or late stage, especially in the late stage, where the tumor grows faster or has more peripheral infiltration, has metastasis in the surrounding lymph nodes, and invades the renal peritoneum and the tissues around the kidney. If the scope of surgery is not large enough, there may be residual, and this residual can lead to recurrence. The key to tumor treatment is early detection and early treatment in order to have a better survival rate, especially the first treatment should be as thorough as possible, and the treatment for the patient is once and for all. If the tumor is treated after recurrence, it will be palliative treatment in most cases, and the effect may be unsatisfactory.
