Staging Kidney Cancer With The Tnm System
The American Cancer Society describes stages of kidney cancer in more detail using the American Joint Committee on Cancers TNM system. In this system, T stands for tumor, N for lymph nodes and M for metastasis.
- T for tumor is T1, T2, T3 or T4.
- A T1 tumor measures 7 cm or smaller in width.
- A T2 tumor is larger than 7 cm.
- A T3 tumor may be any size and has grown into a major kidney blood vessel or into the tissues on the outside of the tumor, but it hasnt reached the adrenal gland.
- A T4 tumor has grown into the adrenal gland.
The ACS describes kidney cancer using the TNM system in this way:
- Stage 1 is T1, N0, M0.
- Stage 2 is T2, N0, M0.
- Stage 3 is T3, N0, M0 or T1-T3, N1, M0.
- Stage 4 is T4, any N, M0 or any T, any N, M1.
How Does Ccrcc Form
Scientists are always working to understand how cancer forms, but it can be hard to prove. Because ccRCC can run in families, we know that changes in the VHL gene are important in causing ccRCC. The VHL gene is also changed in ccRCC from people without a family history of Von Hippel-Lindau syndrome. Scientists have learned a lot about what the VHL gene does in the body. This has given scientists clues about treatments to try for ccRCC.
Review Articlepulmonary Manifestations Of Renal Cell Carcinoma
Renal cell carcinomas most frequently metastasize to the lungs.
-
Renal cell carcinomas may present as pleural effusion in advanced disease stage.
-
Pulmonary emboli are a manifestation of RCC and occur due to a hypercoagulable state.
-
RCC is highly vascularized and may cause arteriovenous fistulas in metastatic foci.
-
RCC may also manifest as paraneoplastic syndromes such as cough, diaphragm paralysis.

Medication Options: What Are Targeted Therapies
There are two general types of medications doctors use to curtail or slow the growth of cancer cells or reduce the size of tumors. One is a category called targeted therapies. Most are given as pills, and they focus on specific proteins or other molecules found on the surface of or inside the cancer cell in order to battle the cancer. There are two main categories of targeted therapies: VEGF inhibitors and mTOR inhibitors. According to Dr. Liu: VEGF inhibitors are the workhorse for kidney cancer treatment. These drugs work by preventing blood vessels in and around the tumor from growingsomething thats necessary for cancer cells to multiply. Some of the most-common side effects include diarrhea, headaches, hair loss, numbness, or a stuffy nose.
The mTOR inhibitors are drugs that work by hampering a protein needed for tumor cells to grow and divide. However, mTOR monotherapy is less effective than a VEGF inhibitor, says Dr. Liu. Your doctor might prescribe this as a second line of treatment when other drugs arent working. Side effects include mouth sores, loss of appetite, fatigue, swelling in the arms or legs, or breathing problems.
How To Manage Your Symptoms
Palliative care can relieve symptoms like pain, fatigue, and nausea. This treatment won’t cure your cancer, but it can help you feel better. You can still get your other cancer treatments while you’re getting palliative care.
Palliative care can include:
- Pain relievers and other medicines
- Relaxation techniques

Systemic Therapy For Stage Iv Renal Cell Cancer
Systemic therapy is any treatment directed at destroying cancer cells throughout the body and is the cornerstone of treatment for metastatic and recurrent cancer. Systemic therapies used for the treatment of RCC include chemotherapy, immunotherapy, and/or precision cancer medicines.4-15 The current standard of care combines checkpoint inhibitor immunotherapy with the precision cancer medicine Inlyta® .4-6
Inlyta is a small-molecule tyrosine kinase inhibitor that works by blocking certain proteins that play a role in cancer growth. The developers of the checkpoint inhibitor immunotherapy drugs Keytruda and Bavencio both elected to combine their medication with Inlyta in order to determine their effectiveness in the treatment of advanced RCC.
How Common Is Renal Cell Carcinoma
Renal cell carcinoma accounts for almost all kidney cancers.
- Renal cell carcinoma accounts for about 8% of all malignant tumors of the kidney. It most commonly occurs in teens and young adults. In adults, there are about 64,000 new cases each year.
- Renal cell carcinoma is rare in children younger than 15. In teens ages 15 to 19, renal cell carcinomas represent two-thirds of all kidney cancers.

However, I’ve only been going through the treatment for one and a half years. Mine has been fairly aggressive though. My mets exist in my bones and more recently in my lungs. The lung mets are new but they are growing quickly and multiplying.
I’ve been through Votrient, two separate immunotherapy clinical trials, and just now going on Afinitor and Lenvima. My neurosurgeon and radiation oncologist have given me prognoses of two to twelve months. My medical oncologist thinks I may have more than a year until death.
I’ve had severe side effects from the pill form medications, too. So, I know where your husband is coming from sick and tired of being sick and tired. The mets in my spine have caused spinal cord and nerve compression which has left me in extreme pain. The bone mets are extremely painful as well. If I were to decide to stop the treatment from cancer, I would still need treatment for my pain.
I can’t give you any inside information about the absolute last days, but I know, and my family knows that I don’t have long to go. If you haven’t already, you should contact someone who deals with end of life financial matters and make sure that the family is taken care of, financially, as well as possible after his passing.
I’m so sorry for your situation. I’m glad, for your husband, that he’s had you to care for him for four long years. I couldn’t do this without my wife’s help. You are a special person.
What Is The Prognosis For People With Ccrcc
The estimate of how a disease will affect you long-term is called prognosis. Every person is different and prognosis will depend on many factors, such as
- Where the tumor is in your body
- If the cancer has spread to other parts of your body
- How much of the tumor was taken out during surgery
If you want information on your prognosis, it is important to talk to your doctor. NCI also has resources to help you understand cancer prognosis.
Doctors estimate ccRCC survival rates by how groups of people with ccRCC have done in the past. Because there are so few pediatric ccRCC patients, these rates may not be very accurate. They also dont take into account newer treatments being developed.
With this in mind, ccRCC patients with smaller tumors have a better chance of survival than patients with larger tumors. The 5-year survival rate for patients with ccRCC is 50-69%. When ccRCC is already large or has spread to other parts of the body, treatment is more difficult and the 5-year survival rate is about 10%.

Foods That Are High In Salt
Salt can disrupt the fluid balance in your body and lead to high blood pressure. This can make any loss of kidney function worse.
Processed foods are typically high in sodium, so its in your best interest to avoid:
- fast food
- salty snacks
- deli meats
Whenever possible, use herbs and spices for flavoring instead of salt. However, if youre using exotic herbs, check with your healthcare provider.
Where Do These Numbers Come From
The American Cancer Society relies on information from the SEER* database, maintained by the National Cancer Institute , to provide survival statistics for different types of cancer.
The SEER database tracks 5-year relative survival rates for kidney cancer in the United States, based on how far the cancer has spread. The SEER database, however, does not group cancers by AJCC TNM stages . Instead, it groups cancers into localized, regional, and distant stages:
- Localized: There is no sign that the cancer has spread outside of the kidney.
- Regional: The cancer has spread outside the kidney to nearby structures or lymph nodes.
- Distant: Includes cancers that have spread to distant parts of the body such as the lungs, brain, or bones.

What Is Advanced Kidney Cancer
Lets start with the basics: Renal cell carcinoma, the most common form of kidney cancer, grows within the kidney, but it can spread beyond the kidney itself. If the cancer spreads, its referred to as stage IV kidney cancer or metastatic kidney cancer. Kidney cancer can spread both near and far, from the adrenal gland that sits atop the kidney to the lymph nodes that are scattered around the body. The most common sites for the tumor to spread include the bones, lungs, and brain. Its scary stuff, for sure, but there are several different routes to treating advanced kidney cancer. The path you take will be something youll discuss with your doctor.
Other Terms Used For Cancer Stages
Your doctor may use other terms to describe the stage of the cancer:
Early or local
A small cancer that has not spread.
Locally advanced
Cancer that has started to spread into surrounding tissues or nearby lymph nodes, or both.
Local recurrence
Cancer that has come back in the same area after treatment.
Secondary, advanced, widespread or metastatic
Cancer that has spread to other parts of the body.

What Is A 5
A relative survival rate compares people with the same type and stage of kidney cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of kidney cancer is 80%, it means that people who have that cancer are, on average, about 80% as likely as people who dont have that cancer to live for at least 5 years after being diagnosed.
What Is Renal Cell Carcinoma
Renal cell carcinoma , also called renal cell cancer or renal cell adenocarcinoma, is a common type of kidney cancer. Renal cell carcinomas account for about 90 percent of all kidney cancers.
RCC usually begins as a tumor growing in one of your kidneys. It can also develop in both kidneys. The disease is more common in men than women.

Treatments For Cancer In Your Bones
Some treatments shrink the cancer. Others protect your bones from the damage the cancer can cause. And some therapies ease your symptoms to help you feel better.
Targeted therapy. These medicines go after substances that help cancer cells grow and survive. Theyâre designed to kill cancer without harming healthy cells.
Tyrosine kinase inhibitors target proteins that help cancer cells and their blood vessels grow. These drugs include:
Bevacizumab is another type of targeted therapy. It blocks a protein called VEGF, which helps tumors grow new blood vessels.
mTOR inhibitors target the mTOR protein, which helps cancer cells grow. They include everolimus and temsirolimus .
Immunotherapy. Also called biologic therapy, these medicines use substances made in a lab or by your body to fight kidney cancer. There are a few types:
- Interleukin-2
- Checkpoint inhibitors, such as nivolumab
Radiation. In this treatment, a machine beams high-energy X-rays to kill cancer cells inside your body. It can relieve pain in your bones. It also can prevent weak bones from breaking. If you already have a fracture, killing cancer cells with radiation will help it heal faster.
Surgery to remove cancer from your bone can relieve pain, prevent fractures, and make it easier for you to move around.
Drugs to strengthen bones. A few medicines can make bones stronger, and prevent pain and fractures.
Tnm Staging And The Stages Of Kidney Cancer
Kidney cancer is described in stages that the American Joint Committee on Cancer developed. The system is better known as the TNM system.
- T refers to the tumor. Doctors assign a T with a number thats based on the size and growth of the tumor.
- N describes whether the cancer has spread to any nodes in the lymph system.
- M means the cancer has metastasized.
Based on the characteristics above, doctors assign RCC a stage. The stage is based on the size of the tumor and the spread of the cancer.
There are four stages:
- Stages 1 and 2 describe cancers in which the tumor is still in the kidney. Stage 2 means that the tumor is larger than seven centimeters across.
- Stages 3 and 4 mean the cancer has either spread into a major vein or nearby tissue or to lymph nodes.
- Stage 4 is the most advanced form of the disease. Stage 4 means that the cancer has spread to the adrenal gland or has spread to distant lymph nodes or other organs. Because the adrenal gland is attached to the kidney, the cancer often spreads there first.

How Cancer Stage Affects Treatment
The best treatment for kidney cancer depends on the stage, along with the patients general health. The most common options include:
- For stage 1, surgery to remove the part of the kidney with the tumor may be the most appropriate choice. This surgery is called a partial nephrectomy.
- For stage 2, the whole kidney may be removed. This surgery is called radical nephrectomy.
- For some stage 3 cancers may involve a radical nephrectomy to remove the affected kidney, lymph nodes and nearby cancer cells, as well as the adrenal gland and fatty tissue.
- For stage 4 kidney cancers, other treatment options separate from surgerysuch as targeted therapies or immunotherapymay be recommended.
Renal Cell Carcinoma Staging
Doctors who diagnose and treat RCC and other types of cancer use a staging system. Each person with RCC is given a number designation ranging from 1 to 4. Stage 1 is the earliest stage of the disease and stage 4 is the latest and most advanced.
Staging for RCC is based on:
- size of the primary tumor in the kidney
- spread of cancerous cells from the primary tumor to nearby tissues
- degree of metastasis
- spread of the cancer to other organs in the body
Stage 4 RCC can include different combinations of staging criteria:
- When the primary tumor is large and has spread throughout the kidney and into nearby tissues. In this instance, the cancer cells may or may not have spread into other organs in the body.
- When the cancer has metastasized and is present in distant organs. In this case, the primary tumor may be of any size, and there may or may not be any cancer in the tissues immediately surrounding the kidney.

Recurrent Renal Cell Carcinoma
Renal cell cancers typically develop resistance to treatment. Resistant cancer may return locally in the area of the kidney, or in other parts of the body such as the lungs or bones. Its important to understand that not all sites of recurrence are the same. Different cancer causing mutations may lead to resistance in different locations of the body and some of these resistant cancers can be effectively treated by surgical removal while areas continue to respond to systemic treatment.
Standard treatment for recurrent cancer is with the checkpoint inhibitor combinations if not already used, otherwise combinations of other precision cancer medicines, immunotherapy, or participation in a clinical trial utilizing new, innovative therapies may provide the most promising treatment. There are several medications approved for the treatment of advanced or recurrent RCC.
Doctors can perform NGS – biomarker testing on a biopsy sample to help determine whether surgery may be beneficial and to identify cancer driving mutations that could be treated with newer precision cancer medicines available through clinical trials.
- Systemic therapy is cornerstone of treatment with checkpoint inhibitor immunotherapy.
- TKI therapy is preferred if checkpoint inhibitor has already been used.
- NGS – biomarker testing to determine if isolated metastases can be surgically removed and to determine clinical trial participation.
