Kidney tumor ablation, specifically cryoablation, has emerged as a minimally invasive alternative to traditional surgical treatments like nephrectomy. As a relatively novel approach, it’s essential to understand the indications, risks, benefits, and outcomes of cryoablation for kidney tumor management. In this article, we will explore these aspects and compare cryoablation to the more conventional nephrectomy procedure.<\/p>\n

Intro to Renal Cell Carcinoma<\/strong><\/p>\n

Renal cell carcinoma (RCC) ranks third in the world in terms of morbidity among malignant neoplasms of the genitourinary system after tumors of the prostate and bladder. In terms of the growth rate of cancer incidence in North America, RCC steadily ranks second after prostate cancer. <\/span>Every year, in the United States more than 65,000 men and women get kidney cancers, and about 14,000 men and women die from this diseases.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0The widespread introduction of modern diagnostic methods has led to an increase in the detection rate of early-stage RCC. Currently, there is a decrease in the size of the primary detected kidney tumors with an increase in the proportion of T1 or low grade tumors and a decrease in the proportion of advanced RCC because of early detection and treatments. The number of patients with a tumor <4 cm in diameter has steadily increased. These trends undoubtedly led to an improvement in survival rates in these groups of RCC .<\/span><\/p>\n

\u00a0 \u00a0 \u00a0In connection with the migration of the stage of the tumor process towards localized RCC with a small tumor, new organ-sparing methods of treating RCC have been developed in the last two decades, such as laparoscopic kidney resection and most impressively ablative minimally invasive techniques such as cryoablation and microwave ablation both of which are done at LA Vascular.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0The essence of a relatively new minimally invasive direction in oncourology consists in the local destruction of the tumor process, when energy is supplied to the lesion, leading to damage (ablation) of the affected area. These technologies are collectively called ablative techniques. Modern ablative approaches include both hyperthermal (radiofrequency ablation – RFA or newer microwave techniques) and hypothermal (cryoablation) methods which have the largest amount of supportive clinical data.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0Ablative techniques destroy tumor tissue in situ (within the body) without requiring removal (surgical resection of the mass). Their main potential advantages include low complication rates, no hospital stay, earlier return to normal life, as well as preservation of parenchyma and renal function, lower cost of treatment and the possibility of treating patients with severe comorbidities who may not be candidates for surgery<\/span><\/p>\n

Cryoablation: An Overview<\/strong><\/p>\n

Cryoablation is a minimally invasive treatment that uses extreme cold to destroy targeted tissue, such as kidney tumors. This procedure involves the insertion of a cryoprobe into the tumor under image guidance (typically CT or ultrasound). The cryoprobe then cools the surrounding tissue, forming an iceball that destroys the tumor cells.<\/p>\n

Indications for Kidney Tumor Cryoablation<\/strong><\/p>\n

Cryoablation is typically indicated for patients with:<\/p>\n

    \n
  1. Small renal masses (usually less than 4 cm in size)<\/li>\n
  2. Localized tumors without evidence of metastasis<\/li>\n
  3. Poor surgical candidates due to medical comorbidities or advanced age<\/li>\n
  4. Solitary kidneys or a risk of future kidney function decline<\/li>\n<\/ol>\n
