Bladder Cancer Treatment Options

The bladder is an organ in the lower pelvis responsible for storing urine. When cells in the bladder start to grow out of control, they can form tumors leading to bladder cancer.

Urothelial cancer is the most common form of bladder cancer and impacts around 80,000 people per year. This form of bladder cancer starts in the urothelial cells that line the inside of the bladder. Urothelial cancer may also occur in other areas of the urinary lining such as the inside of the kidneys (renal pelvis) and the tubes connecting the kidneys to the bladder (ureters)

The Weill Cornell Medicine Genitourinary (GU) Oncology Program works with a wide range of GU specialists to tailor treatments for each patient depending on their disease type and if they have metastatic disease, which is when the cancer has left the bladder or other areas of the urinary system and spread to other parts of the body through the lymph nodes or bloodstream.

Here are some of the treatment options offered for bladder cancer patients.

Chemotherapy

Chemotherapy is a common treatment option for patients with bladder cancer and can be given at a number of times throughout the treatment process. Chemotherapy may be given directly into the bladder or into veins before surgery to make a tumor easier to remove, after surgery or radiation to kill remaining cancer cells, or as a main treatment option for patients with metastatic disease.

Radiation Therapy

Another type of treatment used for bladder cancer is radiation. Radiation may also be given throughout the treatment process. It can be used after surgery, as a main treatment for earlier-stage cancers that may not require or be able to receive surgery or chemotherapy, or as part of a treatment regimen for advanced or metastatic disease. Radiation is often given along with chemotherapy to help the radiation work better, which is known as chemoradiation.

Stereotactic body radiation therapy (SBRT) is a type of radiation therapy that uses x-rays to kill tumor cells. This method is able to deliver radiation precisely to the tumors and may kill tumor cells with fewer doses over a shorter period compared to other types of radiation.

Immunotherapy

Immunotherapy drugs help the body’s immune system fight cancer by instructing the immune system to identify and destroy cancer cells.

There are a number of approved immunotherapy options that may be given to patients in a variety of different circumstances. Immunotherapy can be used in patients with non-muscle invasive bladder cancer though instillation in the bladder, into veins as an additional therapy after surgery, or into veins for advanced cancer.

One of the most common versions of immunotherapy are drugs called immune checkpoint inhibitors. Immune checkpoints are part of the natural body to keep the immune system from attacking normal cells (when this happens, we call it “autoimmunity”). Checkpoint inhibitors target “checkpoints”, or proteins on the immune cells, that cancer cells use to hide from the immune system. These drugs block the checkpoints allowing the body’s immune system to attack the cancer.

Surgery

Surgery is often done before or after other treatments in order to best maximize the results. A number of surgical techniques and options exist depending on the type of bladder cancer and whether or not it has spread beyond the urinary system. These range from endoscopic techniques where a tube is inserted into the urinary system to using cameras (often with the assistance of a robot) to open surgery with incisions through the skin. Sometimes the bladder needs to be removed and there are a number of techniques to either divert urine to the skin (often with a bag) or creation of a new bladder (called neobladder).

Clinical Trials

The Weill Cornell Medicine Genitourinary (GU) Oncology Program leads and participates in a number of clinical trials across a spectrum of disease areas, including bladder cancer. Our team is dedicated to evaluating new diagnostic and treatment approaches in order to develop the best options that benefit our patients. Clinical trials may be the right choice for some patients, and we encourage you to speak to your doctor about the options available to you.

Our team is currently leading a clinical trial evaluating the effects of adding radiation therapy to the immunotherapy drug atezolizumab, for the treatment of metastatic bladder cancer. The aim of this trial is to identify if the combination of radiation and immunotherapy may have the ability to boost the results of the immunotherapy drugs and may be more effective at killing tumor cells. Learn more about this trial here.

Another interesting trial has been developed based upon the laboratory work of one of our team members. For patients with bladder cancer invading the muscle layer and needing removal of the bladder (called cystectomy), the usual approach is chemotherapy followed by surgery. However, not all patients are able to safely receive the most effective chemotherapy drug called cisplatin. This trial is evaluating the use of an oral targeted drug called abemaciclib to take prior to surgery for these patients. Learn more about this trial here.

Antibody-drug conjugates are a type of targeted chemotherapy. To date, two have been approved by the U.S. Food and Drug Administration (FDA) in various situations. We currently have trials open to enrollment testing two of these antibody-drug conjugates, enfortumab and IMMU-132, either alone or in combination with other drugs.

Our team is continuously working on new research initiatives and clinical trial participation. You can find a full list of our open bladder cancer trials here.

8 Things You Should Know About Testicular Cancer

testicular cancer awarenessIn the medical world—and especially the genitourinary (GU) world – we’re pretty comfortable having candid conversations about what’s going on below the belt. After all, the “genito” half of our name refers to diseases of the genital organs. April is testicular cancer awareness month and there’s no need for the testes to be a taboo topic. Awareness is key to early detection, so here are 8 things you should know about testicular cancer:

  1. It can develop in one or both testicles. Our bodies aren’t always exactly symmetrical and the same can be said for cancer development. Just because cancer develops in one side, it doesn’t guarantee that the other testicle will be affected.
  2. You shouldn’t feel pain. Testicular pain isn’t normal. Visit your primary care physician and inquire about getting an ultrasound to get a better picture of what’s going on. You may also need a referral to a urologist.
  3. Self-examinations are important. Make an effort to get in a regular habit and aim for once a month. The more you’re familiar with what’s normal for you, the easier it will be to spot something that isn’t right. Not all lumps and bumps mean cancer, but it is important to get them evaluated.
  4. Certain men are at increased risk. While testicular cancer can affect males of all ages, most new cases occur in men between the ages of 20-34. Other risk factors include men who were born with undescended testes (when the testes don’t move into the scrotum during development), men with Klinefelter’s syndrome (two or more X chromosomes), men with a family history of testicular cancer and certain familial cancer syndromes (inherited cancer genes).
  5. Testicular cancer has one of the highest cure rates. We have a number of successful ways to treat testicular cancer, including surgery, radiation, and chemotherapy. Seek out a specialist for evaluation if you sense something is wrong as early detection can minimize the amount of treatment needed. A typical initial work up will include an ultrasound and blood tests, and then possibly a CT scan to get a better picture of what’s going on in your body from a variety of different angles. With proper treatment nearly everyone will be cured, including those with cancer that has spread to other parts of the body.
  6. A diagnosis doesn’t mean you can’t have kids. Most men are able to successfully father children following treatment, but there are occasional situations in which prior history, cancer, or the nature of the treatment can prevent it from happening naturally. Some centers (such as ours) are able to extract sperm, which can be utilized for fertilization. Before starting treatment, ask about your options to preserve fertility, including sperm banking.
  7. It doesn’t signal an end to your sex life either. Following treatment, sexual function should be normal.
  8. Some treatments should only be performed at centers of excellence. For example, in today’s treatment era, some men only need removal of the affected testicle. These men can be spared additional surgery, radiation, and/or chemotherapy that might have been administered in the past, but they remain at risk for tumor recurrence that might be missed in less experienced hands. A type of surgery called retroperitoneal lymph node dissection (RPLND) should only be performed by someone with specialized experience in this procedure. Additionally, certain types of chemotherapy regimens are very complicated and require autologous stem cell support (bone marrow transplant) to achieve cure. We happen to offer all of these specialized approaches.

Studies Highlight Erdafitinib as an Encouraging Bladder Cancer Treatment Option

It has been an especially exciting time for our Genitourinary (GU) Oncology Program. Our team’s bladder (urothelial) cancer research recently made its way into two prestigious medical journals, with both studies highlighting erdafitinib – an oral inhibitor of fibroblast growth factor receptor (FGFR) – as an encouraging therapeutic option for the disease.

FGFR gene alterations are common in urothelial carcinoma and may be associated with low sensitivity to immunotherapy.

In a phase II study of 99 adults with locally advanced or metastatic urothelial carcinoma harboring FGFR gene alterations, Dr. Scott Tagawa and colleagues found erdafitinib to demonstrate impressive tumor control and tolerability. Forty percent of patients responded to the drug, and among the 22 patients who had previously received immunotherapy without success, the response rate jumped to 59 percent.

Weill Cornell Medicine“While not yet confirmed by randomized trial results, the fact that these patients with the unique molecular tumor selection were responsive to erdafitinib and resistant to prior lines of standard therapy makes this a pivotal study,” said Dr. Tagawa. “It’s wonderful to now have this option available for our patients early while awaiting results of the confirmatory randomized trial. It highlights the importance of genomic tumor testing.”

The research group’s findings were published in the New England Journal of Medicine and led to accelerated approval of erdafitinib as the first targeted drug for urothelial carcinoma from the United States Food and Drug Administration (FDA).

In addition to the use of next-generation sequencing of tumors to more precisely select those most likely to respond, the standard erdafitinib regimen also utilizes individualized dosing. Erdafitinib, partly depending on the dose used, is shown to induce increased phosphorus levels in the blood. As blood phosphorus levels are related to targeting of the key pathway (FGFR), the dose of erdafitinib is increased if phosphorus levels do not significantly increase in the absence of any significant side effect. In a retrospective analysis presented at the 2019 European Society of Medical Oncology (ESMO) annual meeting, erdafitinib-treated patients with increased blood phosphorus levels had improved outcomes.

Under the leadership of Dr. Bishoy Faltas, an in-depth analysis of the nuanced molecular characteristics of upper-tract urothelial carcinoma (UTUC) – an aggressive cancer occurring in the lining of the ureter and kidney – supports that erdafitinib has potential to improve the effectiveness of immunotherapy in this patient population.

Whole-exome and RNA sequencing of UTUC patient tumors yielded a number of insights into the biology of the disease – chiefly that it has low immune cells (T cells) and high expression of FGFR3. The research team found that inhibiting FGFR3 with erdafitinib increased the activity of BST2, a gene associated with immune system activation. Thus, combining FGFR3 inhibitors such as erdafitinib with a class of immunotherapy drugs called PD-1/PD-L1 inhibitors can serve as a viable treatment strategy for UTUC in the future.

“By inhibiting FGFR3, we are able to stimulate genes that are associated with activation of the anti-tumor immune response,” said Dr. Faltas. “In the future, we could potentially use this strategy to reverse the T-cell depletion in these tumors.”

Findings from Dr. Faltas et al. were published in Nature Communications.

Erdafitinib is under further investigation and development in an ongoing clinical trial at Weill Cornell Medicine and NewYork-Presbyterian.
