Malignant neoplasm metastatic to kidney, not of primary renal or renal pelvis origin Most are carcinomas Essential features. In surgical pathology based studies, metastasis to kidney is uncommon; usually recognized after the diagnosis of primary tumor and may not be seen until long after that diagnosis. Clinical features. Radiology description. Compared with renal primaries, more often solid and endophytic; no difference in tumor size, polar predominance or CT enhancement patterns AJR Am J Roentgenol ;W Radiology images.
Images hosted on other servers: Metastatic oral squamous cell carcinoma. Metastatic phyllodes tumor. It occurs in one of three ways:. Noticeable symptoms are often a sign that the disease has metastasized. A physical exam and a review of your medical history may prompt further testing to determine the health of your kidneys. In some cases, a urinalysis suggests that the cancer has spread to other body parts. Another useful lab test is a complete blood count, which includes a count of your red and white blood cell levels.
Abnormal levels suggest a possible risk of cancer. Doctors use imaging tests to find the location and size of a tumor. Screenings help doctors determine if the cancer has spread. CT scans and MRI screenings are especially useful in helping doctors diagnose kidney cancer.
Chest X-rays and bone scans can determine whether the cancer has spread to other parts of your body. Imaging also is a useful tool to see if a particular treatment is working. Treatment options for metastatic renal cell carcinoma may include surgery, immunotherapy, or chemotherapy. More Content. Renal Metastases By J. Click here for Patient Education.

Yes No. Renal Pelvic and Ureteral Cancers. Renal Cell Carcinoma. Metastatic Bone Tumors. T3c: The tumor has spread to the vena cava above the diaphragm and into the right atrium of the heart or to the walls of the vena cava.
T4: The tumor has spread to areas beyond Gerota's fascia and extends into the adrenal gland on the same side of the body as the tumor.
These small, bean-shaped organs help fight infection. Lymph nodes near the kidneys are called regional lymph nodes.
Lymph nodes in other parts of the body are called distant lymph nodes. The "M" in the TNM system describes whether the cancer has spread to other parts of the body, called distant metastasis.
Common areas where kidney cancer may spread include the bones, liver, lungs, brain, and distant lymph nodes. Stage I: The tumor is 7 cm or smaller and is only located in the kidney. It has not spread to the lymph nodes or distant organs T1, N0, M0. Stage II: The tumor is larger than 7 cm and is only located in the kidney. It has not spread to the lymph nodes or distant organs T2, N0, M0.
A tumor of any size is located only in the kidney. It has spread to the regional lymph nodes but not to other parts of the body T1 or T2, N1, M0.
The tumor has grown into major veins or perinephric tissue and may or may not have spread to regional lymph nodes. It has not spread to other parts of the body T3, any N, M0. The tumor has spread to areas beyond Gerota's fascia and extends into the adrenal gland on the same side of the body as the tumor, possibly to lymph nodes, but not to other parts of the body T4, any N, M0.
The tumor has spread to any other organ, such as the lungs, bones, or the brain any T, any N, M1. Recurrent: Recurrent cancer is cancer that has come back after treatment. It may be found in the kidney area or in another part of the body. If the cancer does return, there will be another round of tests to learn about the extent of the recurrence.
These tests and scans are often similar to those done at the time of the original diagnosis. It is important for doctors to learn as much as possible about the tumor. This information can help them predict if the cancer will grow and spread or how effective treatment will be.
