Information on kidney cancer treatment


Kidney cancer in the last decade has seen an increase in detection through the finding of small renal masses or tumours with an average enlarge of 2% to 3% per year. Now almost 40-50% of renal tumours are detected in early on stages. Nearly half of these patients are above the age of 60-65. These are often well localized and lesser than 4cm in size.


This rise in incidence is mostly due to the widespread use of kidney cancer treatment through routine abdominal imaging such as ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) for a variety of abdominal situation. Although some of these tumours are benign, they are treated like any other malignant tumour although less radically and with minimally invasive method. Early detection gives an opportunity to detect kidney disease symptoms early and be capable to not only cure an otherwise lethal disease but save the kidney also. The results, therefore, are excellent.


Such tumours are characterized by CT scan if it is already not done. Biopsy is done in selected cases particularly when it is hard to characterize the tumour on the CT scan.




In cryotherapy extreme cold temperatures are used to destroy the tumour. A hollow probe (needle) is inserted into the tumour either through the skin (percutaneously) or during laparoscopy (key whole) cold gases are passed through the probe, creating an ice ball that destroys the tumour. To be sure the tumour is destroyed without too much injures to nearby tissues; the kidney expert carefully watches images of the tumour during the procedure or measures tissue temperature. The type of anesthesia used for cryotherapy depends on how the process is being done.


Kidney cancer treatment-


The treatment varies from surveillance (observation) to local excision of tumours. Local excision (partial nephrectomy) is the process of choice in most cases. On occasions when it is not possible to save the kidney, radical nephrectomy is done. In addition, there are minimally invasive treatments such as radio frequency ablation and cryosurgery.


The treatment is centered on Radio frequency ablation (RFA) using high-energy radio waves to heat where the kidney disease is situated.


Radio Frequency Ablation-


A thin, needle-like probe is placed through the skin and advanced until the end is in the tumour. Placement of the probe is guided by ultrasound or CT scans. Once it is in place, an electric current is passed through the probe, which heats the tumour and destroys the cancer cells. RFA is usually done as an outpatient procedure, using local or general (sleeping) anesthesia. Major complications are uncommon, but they can contain bleeding and damage to the kidneys or other nearby organs.
