Prevalence of Oral Mucosal Lesions in Patients with Hematological Disorders or Cancer: A Cross-sectional Study

Background: Oral cavity, as the main source of complications such as infection, is unfortunately ignored in cancer patients. In this study, the frequency, type, and location of oral mucosal lesions were determined among patients admitted in the hematology and oncology department. Methods: In this cross-sectional study, 88 admitted patients were examined between November 20, 2017 to August 21, 2018. Demographic data, history of smoking, and denture use were documented. Oral examinations were further conducted to evaluate oral soft tissue lesions according to the checklist. Results: 88 hospitalized patients were screened, out of whom 57(64.7%) had at least one lesion. A total of 79 oral mucosal lesions were identified and ulcerative lesions, found in 51 (57.9%) patients, were among the most frequently encountered problems. Pigmented lesions were more prevalent in smokers (P<0.001). Red and white lesions were significantly more than other lesions among complete denture wearing patients. Conclusion: In light of the high prevalence of oral complications in our patients, this study indicates the need for consultation with oral medicine specialist for a timely diagnosis and better management during the treatment process.
