分期1a期比交好，应该是没查到与肾癌有关的基因突变，总的来说乐观

The five-year survival rate of papillary renal cell carcinoma(PRCC) has been reported as 82-90%, which is slightly higher than that of other kidney cancers.^[45] The reduced survival rate has been positively correlated to several factors, which are high nuclear grade and stage, vascular invasion, DNA aneuploidy, and more.^[46] Patients with type 1 PRCC have significantly improved survival rates than those with type 2, which is a reflection of its lower TNM stage with a well-encapsulated tumor.^[47] Compared to other common types of RCC, PRCC exhibits a relatively lower risk of tumor recurrence and cancer-related death after nephrectomy.^[48] Specifically, the cancer-specific survival rate at five years following surgery with PRCC has reached up to 91%, while clear cell RCC and chromophobe RCC were 72% and 88%, respectively.^[46]
