1. What is the cause of oral mucositis?


Mucositis can appear anywhere in the digestive tract, including the oral cavity, causing the patient to feel pain and difficulty in eating and communicating daily.
Oral mucositis often occurs in patients undergoing cancer treatment with methods such as chemotherapy, radiation therapy in the head - chest or neck area, patients with bone marrow transplants, stem cell transplants. .. About 40% of cancer patients undergoing chemotherapy will have inflammation of the lining of the tongue or mouth. This risk is higher in patients treated for cancer in areas such as the head, neck or chest. There are also other factors that increase the inflammation of the oral mucosa in cancer treatment patients such as:
Female gender; History of dry mouth before and during cancer treatment; Being dehydrated; Have a chronic disease such as kidney disease or diabetes; Sudden unexplained drop in body mass index; Poor oral health; Smoking or using alcohol. The anatomical structure of the digestive system includes the mouth, pharynx, esophagus, stomach, and intestines. In which, the mucosa is the membrane that covers the surface, made up of cells capable of rapidly dividing and plays a role of protecting and moisturizing the above organs. Patients with oral mucositis often start with cancer treatment that damages the cells and prevents them from dividing as they should. This leads to the cells having difficulty in repairing and protecting themselves inside the mouth and throat, and stimulates the body to create an inflammatory response to try to protect itself. There are many cancer chemotherapy drugs available today that have a risk of causing oral mucosal ulcers, especially when used in higher doses or more often. For example, weekly treatment with 5-fluorouracil (5-FU) was identified as one of the causes of mouth ulcers.
Radiation therapy for head and neck cancers can also cause inflammation of the lining of the tongue, mouth, throat, and esophagus. Usually, mucosal lesions usually appear in the 3rd or 4th week of radiation therapy and worsen during radiation therapy. Therefore, prophylactic treatment should be initiated from the beginning of radiation therapy with the aim of delaying and reducing the extent of mucosal damage. However, the damage caused by oral mucositis can slowly recover after the end of radiation therapy, so the patient should maintain the habit of gargling until the ulcers are completely healed. In addition, statistics show that patients who are being treated for hematological malignancies have a higher risk of mouth ulcers.
