Cystic Renal Cancer Staging

Cystic Renal Cell Carcinoma Stages

Kidney cancer, also known as renal tubular epithelial cell cancer, can occur anywhere in the kidney. The clinical presentation of cystic renal cancer is similar to that of renal cancer, with gross hematuria, abdominal masses, and pain. Since cystic renal cancer usually has an intact cyst wall, the chance of gross hematuria is lower.

The specific stages are as follows:

Stage I: Kidney cancer cells are located within the renal capsule.

Stage II: Renal cancer cells invade the perinephric fat but are still confined to the perinephric fascia.

Stage III: Renal cancer cells invade the renal vein or local lymph nodes, with or without the inferior vena cava and perirenal fat.

Stage IIIa: Renal cancer cells invade the renal vein or inferior vena cava.

Stage IIIb: Regional lymph node involvement.

Stage IIIc: The renal vein, inferior vena cava, and ipsilateral adrenal gland are affected simultaneously.

Stage IV: Renal cancer cells have metastasized to distant sites or invaded adjacent organs.

Stage IVa: Renal cancer cells invade adjacent organs other than the adrenal glands.

Stage IVb: Renal cancer cells have metastasized to distant sites.

Surgical treatment of renal lesions: Surgery should be the first choice for patients with good physical condition and low risk factors. For patients with severe hematuria, pain and other symptoms caused by renal tumors, palliative nephrectomy and renal artery embolization can be selected to relieve symptoms and improve quality of life. Surgical treatment of metastatic lesions: Surgery can be selected for patients with isolated metastases after radical nephrectomy, renal cancer with isolated metastases, and good behavioral status. Patients with concomitant metastases can undergo surgery simultaneously with renal surgery or in stages according to the patient's physical condition.
