8 Tips for a Healthy Mouth During Cancer Treatment

Four different colored toothbrushes in toothbrush holder.We grow up learning certain truths regarding the need to brush our teeth at least twice a day and visit the dentist on a regular basis, but during cancer treatment, our mouth needs can change.

Cancer treatment is designed to fight the cancer cells in your body, but in doing so can have a wide range of side effects. One of the main side effects of chemotherapy, the standard treatment for prostate, bladder, and testicular cancers, is changes that occur in the mouth. Chemotherapy can lower white blood cell, platelet, and red blood cell counts throughout the body, so patients are at increased risk for infections. Gum diseases, dental abscesses, and cavities are all infections that are prone to worsen during treatment.

While killing cancer cells, cancer treatment can also harm normal cells, such as the cells in the mouth. This can cause problems with your mucosa and gums (the soft lining of your mouth) and the glands that make saliva. Additionally, both chemotherapy and radiation treatment can cause mucositis, a side effect that involves an inflammation of the lining of the mouth and can lead to red, painful sores.

Here are 8 tips to maintain good oral hygiene and ease mouth pain during cancer treatment:

  1. Visit your dentist early in treatment. See if your doctor can identify potential sources of dental infection or irritation prior to starting chemotherapy. Get any dental cleanings, teeth extractions, and fillings at least 2 weeks before starting treatment. This will help to prevent mouth problems so that you can get the most out of your cancer treatment.
  2. Brush your teeth. During treatment, do not neglect brushing your teeth at least 3 times a day. Use a brush with soft bristles and be gentle on your gums. Consider using a toothpaste designed for sensitive teeth and gums, and make sure that your toothpaste contains fluoride to prevent cavities and tooth demineralization, especially if you have a dry mouth. If you wear dentures, make sure that they are adjusted properly with a comfortable fit. Brush and rinse your dentures after meals and do not wear them while sleeping.
  3. Keep your gums healthy. Floss regularly as long as your platelet count is above 20,000. This is to minimize inflammation of the soft tissues in your mouth which can lead to dental disease, bleeding and infection if your blood counts are low. If possible, start a good flossing routine prior to starting chemotherapy so that your gums are healthy going into treatment.
  4. Pay attention to what you eat. What you put in your mouth matters, and not just in terms of maintaining a balanced diet during treatment. Read package labels to find out what’s in the foods you’re eating, as this will help determine what may irritate your mouth. Hot and spicy sauces can increase pain and sensitivity, especially if you have sores in your mouth. Caffeinated beverages and alcohol can increase mouth dryness, and vinegars, citrus and tomato juices have a lot of acidity which can also irritate the mouth. Be in tune with which foods might be triggers, and if eating out, ask whether sauces and dressings can be omitted or served on the side.
  5. Modify your diet as needed. If your mouth is sore, eating soft, bland, room-temperature food may help. If your mouth is dry, you can add extra moisture to foods in the form of sauces, oils, milk or broth to aid in swallowing. Foods such as eggs, yogurt, cottage cheese, soups, cooked vegetables, pudding, milkshakes and smoothies can often be tolerated when your mouth is sore or dry. If you experience taste changes, experiment with different foods at different temperatures.
  6. Cut down on sugar. Avoid foods that have a lot of sugar because your teeth are more vulnerable to infections and cavities during cancer treatment. Beware of sugar content in beverages such as soda, juice, coffee, tea and sports drinks.
  7. Rinse daily with alcohol-free mouthwash. Many types of mouthwash wash contain alcohol, which can burn your mouth and contribute to oral dryness. Keep your mouth moist with an alcohol-free mouthwash. If you suffer from dry mouth, suck on sugar-free lozenges to stimulate saliva flow. Keep your lips moist with a natural lipbalm containing bees-wax or lanolin to prevent chapping or cracking. Do not use petroleum based lip balms as these can contribute to lip dryness.
  8. Know when to speak up. Be sure to reach out to your healthcare team and dentist if you’re experiencing any of the following: Swelling or pain in the mouth or jaw, trouble swallowing, mouth ulcerations that do not heal within one week, white patches in the mouth, a burning mouth sensation, or severe oral dryness.

Using Radiation, Radioimmunotherapy and Radioactive Isotopes such as Lutetium 177 to Treat Prostate Cancer

Radiation is a mainstay in the treatment of prostate cancer. In men with localized prostate cancer (confined to the prostate gland), using radiation can help cure the cancer. In men with advanced disease, radiation can improve survival and help to manage pain.

Radiation can be delivered a variety of different ways. For example, there are external beams that can be used to deliver radiation from an external machine into the prostate, radioactive “seeds” that can be implanted, or ways to inject special radioactive isotopes directly into the bloodstream.

In the United States (U.S.), there are older FDA-approved treatments utilizing radioactive isotopes for men with prostate cancer that has spread to the bones to decrease pain, called samarium-153 (brand name Quadramet) and strontium-89 (Metastron). More recently, a bone-targeted alpha particle called radium-223 (brand name Xofigo®) was approved because it leads to longer overall survival in men with symptomatic metastatic castration-resistant bone metastases. These bone-targeted radioisotopes have been useful because prostate cancer commonly spreads to bone. However, those drugs cannot treat other sites of tumors such as in the prostate, lymph nodes, or lung.

We are also able to use parts of the immune system as a way to deliver radioactive particles or other targeted cancer treatments to the prostate cancer. We have engineered very specific monoclonal antibodies and molecules that will bind only to PSMA, leading to the opportunity for “molecularly targeted” radiotherapy for prostate cancer. When we combine immunotherapy with monoclonal antibodies with radioactive isotopes, we call the treatment approach radioimmunotherapy. Radioimmunotherapy involves attaching a radioactive isotope (such as Lutetium 177) to a cancer-targeting antibody or small molecule that binds only to a specific cancer-related molecule on a tumor cell. This is similar to a “lock and key” scenario, where the antibody or molecule serves as a key that will only recognize a very specific lock (the cancer-related molecule). In prostate cancer, nearly all cells have a specific “lock” that lives on the surface of each cell called prostate-specific membrane antigen (PSMA).

j591_psmaFor nearly 15 years, we have been utilizing a monoclonal antibody known as J591, which is a version of a specific key that will only recognize and enter cells with the specific lock PSMA. We successfully utilized this antibody tagged with small radioactive particles to either visualize or treat prostate cancer tumors within the prostate, bone, lymph nodes, and other sites in the body. Our initial studies demonstrated safety and signaled anti-tumor efficacy. In addition, we showed that the antibody went to virtually all sites of tumors (sometimes discovering new ones) and did not target other normal organs (with the exception of the liver which helps clear the drug from the body). Subsequently, our larger studies have shown responses in larger numbers of patients. In Europe, physicians picked up on our results and Lutetium 177 (also known as Lu-177, 177-Lu or 177 Lutetium) has become a very popular radioactive particle that can be directed to prostate cancer via PSMA. It has been used to kill prostate cancer cells and treat hundreds of prostate cancer patients. This commonly-used approach uses a small molecule which recognizes PSMA to deliver Lu-177 to prostate cancer cells (termed radioligand therapy or radioimmunotherapy therapy).

Lutetium-177 PSMA therapy is associated with a good prostate cancer response and many men travel from all over the world to Europe in order to access this treatment. In the U.S. it is only available via clinical trials, and for more than 10 years, Weill Cornell Medicine and NewYork-Presbyterian have been one of the few centers in the U.S. to offer Lutetium 177 and other targeted treatments using radioactive particles.
