Oral Problems in Oncology Patients Undergoing Chemotherapy for Solid Tumors: A Prospective Observational Study

Simple Summary Several oral problems occurring during cancer treatment can lead to the discontinuation or interruption of the scheduled treatment, with a negative impact on patient's overall survival. Very few studies focused on patients' self-reported oral problems during chemotherapy treatment for solid tumors. Through the administration of a dedicated questionnaire, we aim at correlating the presence of oral complications to demographic and medical information. Metastatic disease represented a risk factor for the onset of oral mucositis and salivary gland hypofunction, while specific chemotherapy regimens increased the risk to develop a subjective reduction in the salivary flow and difficulty in swallowing. Most of the participants were informed by the oncologist about the possibility of oral problems arising during oncological therapies. It is of paramount importance to collect observational data on oral problems from the patients' perspective in order to plan information and prevention campaigns to inform patients about their possible occurrence by providing useful tools for prevention and management.Abstract PURPOSE: Oral problems in a group of oncological patients undergoing chemotherapy (CT) for solid tumors have been examined. Incidence and severity of patients' self-reported oral problems have been evaluated along their interaction with age, gender, tumor diagnosis and stage, presence of mestastasis, CT agent type, and number of CT cycle. We also analyzed the presence of paraesthesia and anaesthesia and their predisposing factors associated with clinical and treatment-related variables. METHODS: Patients were asked to fill in a questionnaire to evaluate the onset and the intensity of oral and perioral pain, oral mucositis, salivary gland hypofunction, dysgeusia, dysphagia, dysphonia, and sensitivity neuropathy (paraesthesia or dysaesthesia) since the last CT infusion. We also investigated which types of medications have possibly been used and who recommended it, as well as patients' degree of awareness about the possibility of oral problems arising during CT. RESULTS: We recruited 194 patients and obtained 491 questionnaires. We found that a metastatic disease was a risk factor for OM (OR 2.02, p = 0.026) and salivary gland hypofunction (OR 1.66, p = 0.042) and that platinum agents, compared to mitotic inhibitors, increased the risk of developing salivary gland hypofunction (OR 2.16, p = 0.013), dysphagia (OR 3.26, p = 0.001), and anaesthesia (OR 5.16, p = 0.041). Young age was a slight protective factor for most symptoms. The 80% of enrolled patients were informed by the oncologist about possible oral problems arising during CT. CONCLUSIONS: Our study highlighted the importance of collecting observational data from the patients' perspective on oral problems arising during the routine oncology practice, across a range of solid tumors and CT regimens. The relevance of these findings focused on the key role of the multidisciplinary team in advising the patients on the possible occurrence of oral problems, also by recommending their management.
