Kidney Cancer

Kidney Cancer

Kidney cancer is a type of cancer that arises from the uncontrolled growth and proliferation of cells in the kidney tissues.

The kidneys are vital organs that filter waste materials and excess water to produce urine. Kidney cancer is often referred to as renal cell carcinoma and has the potential to spread to other organs. Early diagnosis and the selection of appropriate treatment methods are crucial in improving the quality of life for individuals with kidney cancer.

Regular health check-ups after treatment are important for monitoring the patient's condition and detecting potential recurrences early. Every patient should collaborate with their healthcare team to gain detailed information about the treatment process and understand their situation.

Kidney Cancer Symptoms

Symptoms of kidney cancer may not be apparent in the early stages, making the signs more noticeable as the disease progresses. Symptoms of kidney cancer may include:

• Blood in the urine
• Back pain
• Weight loss and loss of appetite
• Fever
• Feeling tired and weak

Each of these symptoms alone may not be sufficient to confirm kidney cancer and may be indicative of other health issues. However, it is crucial to contact a healthcare professional immediately if any of these symptoms are noticed. Early diagnosis can increase the chances of successful treatment and prevent the progression of the disease.

Stages of Kidney Cancer

Staging kidney cancer is a classification used to determine the extent of the disease's spread and the location of the tumor within the body. Staging aids healthcare professionals in creating an appropriate treatment plan and assessing the prognosis of the disease. Kidney cancer is generally categorized into four stages: I, II, III, and IV.

• In stage I, the tumor is usually small and has only affected one kidney, with no spread to surrounding tissues. Often, no other symptoms are observed, and patients at this stage may not be aware of their condition.
• In stage II, the tumor may have grown, but it still only affects one kidney, with no observed spread to nearby lymph nodes or other organs. Symptoms may be mild at this stage, but patients may become aware of their condition.
• In stage III, the tumor may be larger and may have spread to lymph nodes outside the kidney. It may have limitedly spread to surrounding tissues. Symptoms may increase, and patients often experience symptoms such as pain, bloody urine, or weight loss.
• In the final stage, stage IV, the tumor may have spread to organs outside the kidney, such as the liver, lungs, or bones.
• Stage IV is the most advanced and widespread stage of the disease. Symptoms can intensify, and patients often face serious health issues.

Angiomyolipoma and Oncocytoma: What Are They?

Angiomyolipoma is a tumor that typically develops on the cortical surface of the kidneys, containing fat, irregular muscle tissue, and blood vessels. These tumors are often incidentally detected during another medical examination or through imaging methods. Angiomyolipomas are usually benign, tend not to grow significantly, and often do not present symptoms. However, larger angiomyolipomas may carry a risk of bleeding and, in rare cases, may require surgical intervention.

Oncocytoma is a type of tumor where kidney cells accumulate a large amount of a specific type of cell called oncocytes. Oncocytes are cells with a high concentration of mitochondria, the cell organelles responsible for energy production. Oncocytomas are generally small, benign tumors that often do not develop into cancer. They generally do not present symptoms and are usually incidentally detected during imaging tests. Since they rarely exhibit growth tendencies, most cases do not require surgical intervention.

How Is Kidney Cancer Diagnosed?

The diagnosis of kidney cancer is established through a series of tests and imaging methods. The diagnostic process is based on the patient's symptoms, risk factors, and physical examination. Urine and blood tests are used to assess kidney function and detect signs of tumors. Imaging tests, including computerized tomography (CT), magnetic resonance imaging (MRI), and ultrasound, create detailed images of the kidneys to identify tumors.

Intravenous urography allows the visualization of the kidneys and urinary tract through colored X-ray films. Biopsy involves examining tissue samples taken from the kidney to determine the type of tumor. Intravenous contrast tomography (angiography) visualizes blood vessels, helping assess the impact of the tumor on blood vessels.

How Is Kidney Cancer Treated?

Kidney cancer treatment involves a personalized plan determined by various factors such as the patient's overall health, tumor size, stage, and extent of spread. Typically, a combination of different methods, including surgery, radiation therapy, chemotherapy, targeted therapies, and immunotherapy, may be used.

Surgery is the most common method used in kidney cancer treatment. Radical nephrectomy or partial nephrectomy may be employed to remove the tumor. Radical nephrectomy involves the removal of the entire kidney, while partial nephrectomy removes only the tumor and the surrounding healthy tissue. Radiation therapy aims to target cancer cells using high-energy rays to kill them. Chemotherapy is a treatment method that aims to control or kill cancer cells but has limited effectiveness in kidney cancer.

Targeted therapies focus on specific molecules to halt the growth of cancer cells. Immunotherapy boosts the immune system to fight against cancer cells. Kidney cancer treatment generally involves a combination of one or more of these methods. Creating a treatment plan requires the involvement of a multidisciplinary healthcare team to determine the most effective strategy tailored to the patient's needs.
