Evaluation of oral mucositis level and affecting factors in cancer patients receiving chemotherapy

This study aimed to evaluate the severity of oral mucositis and the contributing factors among cancer patients undergoing chemotherapy.

This study was planned cross-sectional. The study was conducted at a medical oncology clinic between January and July 2022. The sample consisted of 245 patients with cancer receiving chemotherapy. Data were collected using a personal, oral health and disease-related characteristics questionnaire and the World Health Organization Oral Mucositis Assessment Scale by researchers. Intraoral examination of the patients was carried out by researchers. The data were analyzed by independent-sample t-tests, Chi-square tests, paired-sample t-tests, and multivariate logistic regression (p < 0,05).

The patients had mean age 62.31 ± 10.70. Patients of 32.7% were with lung cancer. 52%of the patients (n = 128) receiving chemotherapy developed oral mucositis. The independent variables the presence chronic disease(OR:1.85), chemotherapy protocol (OR:3.52) and the dependent variables ECOG performance score (OR:2.25) were variable that affected the development of oral mucositis (p < 0.05). Patients of 35.5% were oral mucositis score of 1. Patients those who had breast cancer, who received doxorubicin or cyclophosphamide chemotherapy protocols, and who had previously developed oral mucositis were found to have a higher rate of oral mucositis (p < 0.05). In addition, oral mucositis was more prevalent in patients with chronic diseases other than cancer (57%), those who used medication continuously (57.2%), those with oral and dental diseases (56.9%), those who had dental check-ups before cancer treatment (79.2%), and those who had information about oral mucositis(70.2%) (p < 0.05).

In conclusion, nearly half of the patients (52%, n = 128) receiving chemotherapy developed oral mucositis and of all patients of 35.5% had an oral mucositis score of 1 in the second round of chemotherapy. Patients those who had breast cancer, who received doxorubicin or cyclophosphamide chemotherapy protocols, and who had previously developed oral mucositis were found to have a higher rate of oral mucositis.
