What is renal cell carcinoma

Renal cell carcinoma is the most common adult kidney tumor. Male to female ratio of about 3.5:1, Often happens after the 40-year-old, sometimes under 30 years of age, the individual only more than 20 years of age. Male smokers is the cause of renal cell carcinoma, and has nothing to do with female smokers. Male smokers exposed to cadmium industry and the environment are higher than the adult renal cell carcinoma. Coffee may increase the risk of renal cell carcinoma, and has nothing to do with coffee consumption. The incidence of renal cell carcinoma have family tendency. Renal cell carcinoma by tubular epithelial cells. Invasive pelvis gradually grow up occurs when hematuria. If penetrating renal capsule can be invasive kidney-fat even in neighboring organs. Renal cell carcinoma> 3 cm that is prone to transfer. Clinical manifestations 1. Early asymptomatic. The main symptoms of tumor development for intermittent painless gross hematuria. 2. Tumor in the lower pole renal or larger, upper abdominal mass and can be. 3. Pain for advanced symptoms, often waist钝痛. 4. Renal performance, fever, hypertension, high blood calcium, multi hyperlipidemia, varicocele, the evil of quality and tumor metastasis symptoms. Diagnosis 1. Aged> 40-year-old male, painless gross hematuria, should be suspected renal cell carcinoma, 2. Urography showed renal lesions. 3. Localized renal ultrasonography showed thickening protrude, renal collecting system Echo compression transfer, intrarenal round hypoechoic mass. 4. CT scan shows that intrarenal substantive bit of lesions. 5. Serum alkaline phosphatase values increased. Treatment principles 1. Early radical nephrectomy; 2. Preoperative renal artery embolization can reduce blood loss and prevent the spread of cancer in the operation. 3. Such as isolation or bilateral renal cell carcinoma contralateral kidney renal cell carcinoma and poor renal function, renal tissue should be held to retain the kidney cancer surgery as some nephrectomy can be a tumor enucleation. 4. Tumor thrombus in the inferior vena cava radical resection of renal while resection or removal vein tumor thrombus within the inferior vena cava thrombosis. 5. Radiotherapy, chemotherapy, immunotherapy and hormone treatment not sure. Medication principle Chemical treatment of renal cancer, immune therapy and hormone therapy results not sure that can be combined two kinds over the treatment effective. Supplementary examination 1. Check box early tumor limited to "A" main, 2. Advanced tumors, including restrictions check box "A" and "B." Evaluation 1. Cured: (1) tumor resection and found no transfer of source; (2) incision healed. 2. Improved: (1) tumor resection, residual metastatic source; (2) After chemotherapy, radiation therapy after tumor regression, symptoms ease. 3. Surprised me: swelling of resection, symptoms, signs of improvement. Experts suggested that Comprehensive annual medical examination may be conducted on a regular basis early detection of tumors. Renal cell carcinoma only effective treatment is radical nephrectomy. Resection of the week, including kidney fat, fascia, the ureter and renal pedicle of the lymph nodes. Yet on the very tumor resection should adrenal. Have unresectable advanced renal cell carcinoma, with interventional therapy after injection of anti-cancer drugs, renal artery embolization can control bleeding, pain relief, the tumor size decreased. With progesterone treatment, some patients have eased role.
