Simple examination, early detection increase oral cancer survival rates
Simple examination, early detection increase oral cancer survival rates Dr. George M. Taybos, left, professor of care planning and restorative sciences in the School of Dentistry, performs an oral cancer exam on Adrianne Davis, an oral radiology technician.
Cancer in the mouth is as common as leukemia, but a 60-second exam by a dentist can mean the difference between life and death.
According to Dr. George M. Taybos of Ridgeland, professor of care planning and restorative sciences at the University of Mississippi Medical Center, the stage at which the oral cancer is diagnosed is critical.
“Oral cancer detected at its early stage has a five-year survival rate of 81 percent compared to 30 percent for the advanced stages of oral cancer,” he said. “Patients should expect their dentist to perform an oral cancer exam at each visit.”
Only 34 percent of oral cancers are detected at an early stage, yet oral cancer occurs on tissues that are easy to examine, Taybos said.
Approximately 30,000 new cases of oral cancer are diagnosed each year in the United States, with an estimated 7,320 deaths. According to the American Cancer Society, oral cancer occurs almost as frequently as leukemia and claims almost as many lives as the most dangerous form of skin cancer, melanoma.
In the last 50 years, the five-year survival for oral cancer has improved very little. It’s currently 61 percent for Caucasians and 39 percent for African-Americans.
Taybos, immediate past president of the American Academy of Oral Medicine, said a thorough examination of all dental patients is appropriate and necessary, and can be performed during routine dental visits.
He attended the Oral Cancer Consortium at New York University last year. The consortium is committed to increasing the awareness of oral cancer among health professionals and the general public.
The public is aware of the need to have annual examinations for early detection of breast, prostate, cervical, and colon cancers, but the same awareness does not exist for oral cancer, he said. And all health care providers are not performing an oral cancer examination.
“There is a lack of confidence in performing a thorough oral cancer examination and the assumption is that an oral cancer examination is someone else’s responsibility.”
Taybos teaches his students to perform an oral cancer examination on every patient every time the patient presents for treatment.
“The examination takes less than 60 seconds, and may save a patient’s life,” he said.
It consists of checking the tongue palate, inside of the cheeks and lips for any bumps or unusual sores.
Symptoms include an ulcer that does not heal; a “lump or bump” in the mouth that may be increasing in size; difficulty and/or pain on chewing and swallowing; soreness when moving the tongue; numbness in areas of the head and neck; and dentures that may not fit because of growth or the presence of an ulcer.
Oral cancer most often strikes adults over the age of 40 and affects twice as many men as women. Those individuals who use any form of tobacco products, especially combined with the use of alcohol, are at increased risk for oral cancer. However, more than 25 percent of oral cancers occur in nonsmokers with no other risk factors.
According to Taybos, the University of Mississippi Medical Center has a very strong team approach to managing patients with an oral cancer. The Head and Neck Tumor Conference, consisting of head and neck surgeons, radiation oncology, hematology oncology, and speech therapy, work together to provide the best options for treating and rehabilitating oral cancer patients.
“With this tumor conference and the individual Medical Center participants, there is no reason that a citizen of Mississippi should feel that he or she has to leave the state in order to have ‘top quality’ treatment for his or her oral cancer,” he said. “Patients can and do receive that treatment right here at UMC.”
According to Taybos, 90-95 percent of all oral cancers occur on the soft tissues of the mouth, and these tissues can easily be examined by health care providers.
“To quote a Chinese proverb, ‘a thousand mile journey begins with one small step.’ Initially we must insure that health care professionals are diligent in their examination of the oral tissues; then we must develop strategies to inform the public of the need to have an oral cancer examination,” he said. “Oral cancer may not be one of the most prevalent malignancies, but the treatments can adversely affect your life. The surgical approach is sometimes extremely physically compromising.
“Detection of the oral cancer at an early stage will result in an increased rate of survival as well as less invasive treatments.”
Oral cancer can be prevented by eliminating risk factors such as tobacco product use and excessive alcohol consumption. Using a lip balm that contains sunscreen also will reduce the risk of lip cancer. Additionally, studies indicate that eating fruits and vegetables as part of a low-fat, high-fiber diet may reduce the risk of cancer.
