Kidney Cancer – It Takes a Team

By Ana M. Molina, M.D.

Each year, about 63,000 people in the United States are newly diagnosed with kidney cancer. Whether you’re still undergoing testing to determine whether you have kidney cancer or have already been diagnosed, you may be wondering where to turn next and who to trust.

Kidney cancer requires a multidisciplinary, team-based approach to treatment and that includes you as a key member of the team. For advanced cancers, your medical oncologist should act as your quarterback to help you navigate your next play. Your medical oncologist will work with you and recommend treatments and next steps based on your wishes and goals for treatment. The oncologist will account for factors such as the type of kidney cancer you have, the size and placement of the tumor and whether the cancer has spread to other organs throughout your body. This can also be referred to as the process of cancer staging and management.

From the time of your diagnosis and throughout the course of your treatment, you will be meeting with a variety of specialists who all provide different expertise.

In honor of March being National Kidney Cancer Awareness Month, here’s an overview of all the players:

Urologist: Urologists specialize in diseases of the urinary tract, including the kidneys, and the male reproductive organs. Within this field, there are sub-specialists who specifically focus on urological cancers. A urologic surgeon who specializes in oncology will be the one who determines whether the tumor can be surgically removed. Based on the size and placement of the tumor, all or part of the kidney may be removed. If only the cancerous part of the kidney is removed, it is called a partial nephrectomy. If the entire kidney is removed, the procedure is called a radical nephrectomy. Whenever possible, it is advantageous to have a partial nephrectomy in order to save nephrons – the kidneys’ filtering units—and preserve kidney function. Following surgery, you will meet with the urologist to review the pathology results and discuss next steps.

Medical Oncologist: This doctor specializes in monitoring and treating your kidney cancer using medical intervention. A medical oncologist can recommend a wide-range of treatment options such as clinical trials, chemotherapy, immunotherapy, combination therapies and targeted therapies. At the Weill Cornell Genitourinary (GU) Oncology Program, we also offer personalized care in the form of precision medicine. This involves tumor profiling to analyze the genetic makeup of your kidney cancer. Based on the results of this analysis, we’re able to select treatment choices that most closely match the vulnerabilities of your specific tumor(s). The medical oncologist will refer you to a urologic surgeon or radiation oncologist if these interventions will offer the best course of treatment for your specific situation.

Radiation Oncologist: This specialist delivers cancer treatment using x-rays and other forms of radiation to treat metastatic kidney cancers. At Weill Cornell, we currently offer clinical trials that combine immunotherapy and radiation which has been shown to have an abscopal effect, meaning that this combined treatment has been able to activate the body’s immune system in order to eliminate tumors that weren’t directly targeted by the radiation.

Radiologist and Interventional Radiologist: Radiologists are the doctors who review imaging tests ordered by your urologist or medical oncologist to determine the location of your cancer and whether it has spread. Imaging tests you may receive include: computed tomography (CT) scans, magnetic resonance imaging (MRI), positron emission tomography (PET), ultrasonography and x-rays. A sub-specialty within radiology, the interventional radiologist is the person who will use image-guided tests to conduct minimally invasive procedures. For example, the interventional radiologist will biopsy organs and tissue in order to collect samples from your tumor. These samples will be examined by pathologists and may ultimately be used for precision medicine and to test out which treatments may be most beneficial to your specific cancer.

Nephrologist: This is the doctor who specializes in treating kidney disease and preserving your remaining kidney function. Nephrologists also work with your healthcare team to help manage other risk factors for kidney failure such as diabetes and hypertension, and to ensure you’re on a kidney-protective regimen. Since many medications are “cleared” by the kidneys, this may involve changing your medications to reduce the stress on the kidneys to filter these medications out of your body as waste.

Palliative Care Physician and Social Worker: Palliative care is often wrongly interpreted as a synonym for end-of-life care and hospice. The field of palliative care, or supportive medicine, is more accurately described as the services that help improve quality of life. It is beneficial for this team to get involved early, as these experts help alleviate some of the symptoms of kidney cancer and its treatment, while even helping to extend life. A palliative care physician can help manage pain and help to reduce uncomfortable side effects such as diarrhea and nausea. They also provide counseling and other therapeutic interventions to help people cope with the emotional impact a cancer diagnosis can have on patients and their loved ones.

At the Weill Cornell GU Oncology Program, we have weekly tumor board meetings in which many of the specialists listed above all meet together to discuss our patients’ care. This close collaboration with experts across kidney cancer sub-specialty areas helps ensure that our patients are receiving the best, most comprehensive and cutting-edge treatment. Because we have a shared system of medical records across the Weill Cornell Medicine healthcare network, communication between our physicians is integrated and seamless.

We understand that it’s not only your medical team that provides support and care during the course of cancer treatment. Our Kidney Cancer Support Group brings together other patients, caregivers and loved ones so that you’re part of a community that “has been there” and understands what you’re going through.

Cancer: A Wolf in Sheep’s Clothing

Immunotherapy wolf in disguiseCancer cells can be pretty sneaky, altering their make-up or microenvironment to avoid detection by our body’s immune system. As a result, the immune system, which is designed to fight off “invaders,” can’t detect cancer as foreign and doesn’t have its guard up.

Earlier this month, NewYork-Presbyterian Hospital kicked off a new ad campaign highlighting how immunotherapy is working to change just that. Immunotherapy treatments are designed to help activate the immune system and kick it into high gear, helping it fight the very cancer it was previously unable to detect.

New scientific discoveries happening right here at Weill Cornell Medicine are making this possible. Our physician-scientists and researchers at the Meyer Cancer Center have found ways to help the immune system better recognize and destroy cancer cells by designing new immunotherapy drugs, cancer “vaccines,” and combination treatments. Through precision medicine and an individualized approach to cancer care, we are developing new ways to treat cancer more successfully than ever before. And, we’re accomplishing these results with less toxicity.

Over the past decade, the U.S. Food and Drug Administration (FDA) has approved several new immunotherapy drugs for advanced cancers. At the Weill Cornell Genitourinary (GU) Oncology Program, we have greatly contributed to the efforts to obtain FDA-approval for immunotherapies for GU cancers, including kidney cancer, bladder cancer, and prostate cancer.

For kidney cancer, we have been involved in many studies of drugs utilizing the immune system to fight cancer, including the phase 2 clinical trial that formed the basis for the large trial leading to the FDA approval and general availability of nivolumab (Opdivo) for renal cell carcinoma. Nivolumab is an immunotherapy that works by allowing the body’s existing immune system to kill tumors. Our team is now working on ways to improve this drug and other types of drugs.

For bladder and other urothelial cancers, we have been instrumental in the development of several antibodies that can be used with and without chemotherapy. Sacituzumab Govitecan (IMMU-132), an antibody-drug conjugate, has had remarkable preliminary activity. It works by leveraging the immune system and bringing a powerful drug directly to the interior of cancer cells in order to kill them from the inside out. We are continuing to use this drug as well as other immunotherapeutic agents to improve outcomes for patients with these types of cancer.

Based upon several scientific properties, prostate cancer is a good tumor type for immunotherapy, and in fact, the first therapeutic cancer vaccine (used to treat cancer rather than prevent cancer) was approved for prostate cancer. At Weill Cornell Medicine, exploiting the immune system remains a focus in fighting prostate cancer, with a number of ongoing and upcoming clinical trials. Weill Cornell Medicine continues to be a worldwide leader in work with monoclonal antibodies, which are proteins (like a “key”) that very specifically target cancer cells (with a specific “lock” that is not present on normal cells). In particular, our work with antibodies against prostate-specific membrane antigen (PSMA) has led to the development of several targeted therapies for prostate cancer. These antibodies can be linked to powerful radioactive particles or drugs that seek out prostate cancer cells (like a smart bomb). For men with prostate cancer whose PSAs rise despite hormonal therapy, we are leading a study of targeted radioimmunotherapy that aims to prevent metastatic disease. In addition, the antibody itself may be able to generate an immune response in prostate tumors and lead to clearance of circulating tumor cells. We are also working on developing vaccines for men with rising PSAs following surgery or radiation.

We continue to examine many promising, cutting-edge immunotherapies through our robust clinical trial program. Click the below links to learn more about eligibility and open clinical trials across the spectrum of GU cancers:
