The immunotherapy for kidney cancer often involves the use of interferons or interleukins, and the results are generally satisfactory. The effects of radiotherapy and chemotherapy for kidney cancer are not very certain. Typically, after kidney cancer is diagnosed, radical nephrectomy is performed. During the surgery, adequate exposure is essential. The renal hilum should be ligated first to prevent cancer cells from being squeezed into the bloodstream during surgery. It is also necessary to remove the fascia and fat around the kidney, along with the lymph nodes at the renal hilum. Combining these surgical measures with immunotherapy usually yields very ideal results.

What are the symptoms of kidney cancer?

Kidney cancer is a common tumor in urological surgery, and a typical symptom in patients with kidney cancer is the appearance of hematuria. The characteristic of this hematuria is that it is painless visible hematuria throughout the course. Initially, the severity of the hematuria is relatively mild, occurring intermittently. However, over time, the hematuria gradually worsens, and the intervals shorten, even leading to significant bleeding. Another symptom of kidney cancer is back pain, which is caused by the increased size of the tumor pulling on the kidney, causing pain. When the tumor presses, it can also lead to severe back pain. A mass is another common symptom of kidney cancer; when a mass is felt on one side of the upper abdomen or back and moves up and down with respiration, it is generally indicative of the late stages of kidney cancer. Therefore, the typical symptoms of kidney cancer are hematuria, pain, and a mass.

Is stage II kidney cancer considered early stage?

The staging of kidney cancer is primarily based on the size of the tumor, whether there is lymph node metastasis, involvement of adjacent organs or lymphatic vessels, and metastasis to distant organs. The TNM staging system is commonly used in clinical settings to stage kidney cancer, where "T" represents the depth of tumor invasion, "N" represents the status of lymph node metastasis, and "M" represents distant metastasis. Stage II refers to a tumor with a maximum diameter greater than seven centimeters but confined to the kidney. Stage II is further divided into stage IIA and stage IIB. Stage IIA refers to a tumor with a maximum diameter greater than seven centimeters but less than ten centimeters, confined to the kidney. Stage IIB refers to a tumor with a maximum diameter greater than ten centimeters, but still confined to the kidney. In the case of stage II kidney cancer, although it is an early stage, curative treatment can be achieved through surgery. Therefore, if diagnosed with stage II kidney cancer, it is vital to pursue aggressive treatment.

How long can someone with kidney cancer and hematuria survive?

A common symptom of kidney cancer is painless visible blood in urine, which is also the primary initial symptom. It is intermittent and sometimes accompanied by blood clots. However, after exhibiting this symptom, how long a patient can live depends on individual constitution and the severity of the condition. Once discovered, early surgical treatment is recommended, followed by immunotherapy, such as using interferons and interleukins.

Will a stage 1 kidney cancer recurrence occur after nephrectomy?

Stage I kidney cancer generally belongs to early-stage kidney cancer, which usually presents no symptoms and is most often discovered during physical examinations. This is the case for more than 50%-60% of kidney cancers. The examination for kidney cancer also requires a CT scan of the kidney and an enhanced CT scan to confirm the diagnosis. If it is stage I, the cure rate through surgical removal is very high. Surgical operation is the first choice for treating kidney cancer and is recognized as a means to cure kidney cancer. Early-stage kidney cancer can be treated with laparoscopic or traditional open surgery, which involves a radical removal of the kidney. For patients with stage I kidney cancer, the five-year survival rate can reach about 92%. Post-surgery, regular follow-up visits are necessary to check for recurrence, metastasis, and new tumors. After surgery, stage I kidney cancer patients should have follow-up visits every three to six months for the first three years and annually thereafter. Stage I kidney cancer has a chance of being completely cured but also the possibility of recurrence, so regular follow-ups are essential.

How many centimeters is kidney cancer in the early stage?

Generally speaking, kidney cancers smaller than 4 centimeters are usually considered early stage, but it still depends on individual circumstances, such as whether the tumor has spread or metastasized, and the malignancy level of the tumor cells. Thus, assessing whether it is early or advanced stage requires consideration of these specific factors, and it cannot be simply determined by size alone.
