Research on the Current Status and Influencing Factors of Oral Health of Breast Cancer Patients during Chemotherapy

Objective: To explore the current status of oral health of breast cancer patients during chemotherapy and to analyze its influencing factors. Methods: From July 2024 ~ February 2025, 409 breast cancer patients who received chemotherapy routinely in three tertiary hospitals were selected as the survey subjects. At the same time, laboratory indicators such as hemoglobin, leukocytes, neutrophils, and C-reactive protein, as well as unstimulated salivary flow rate and salivary PH value, were collected, and multiple linear regression analysis was used to screen the influencing factors of oral health. Results: The oral health status score of breast cancer patients during chemotherapy was (5.12±2.86), and multiple linear regression analysis showed that age, oral disease history, oral PH value, unstimulated salivary flow rate, combined immunotherapy, vomiting during chemotherapy, white blood cell count, lymphocyte count, oral health literacy, and oral self-care efficacy were all influencing factors of oral health status during chemotherapy in breast cancer patients (all P<0.05). Conclusion: The oral health status of breast cancer patients during chemotherapy is moderately low, and it is related to a variety of factors, so medical staff should pay attention to their oral health problems and formulate targeted oral care plans to improve the oral health of patients.
