Cold-associated laryngopharyngeal dysesthesia syndrome after oxaliplatin treatment

Abstract

Objective Oxaliplatin is a platinum-group chemotherapeutic agent commonly used in the treatment of colorectal cancer. In addition to hematological and gastrointestinal side effects, laryngopharyngeal dysesthesia associated with cold is reported as a rare side effect. In this article, seven cases with pharyngolaryngeal dysesthesia were presented and the diagnosis and treatment planning were reviewed in the light of literature findings. Material and Methods Patient records of cancer patients with laryngopharyngeal dysesthesia were retrospectively analyzed between 2020 and 2023. Demographic characteristics, presenting complaints, vital signs, physical examination, and laboratory tests of the patients diagnosed with laryngopharyngeal dysesthesia were recorded. Results Seven patients who had gastrointestinal malignancy and oxaliplatin chemotherapy were diagnosed with laryngopharyngeal dysesthesia. The symptoms most commonly developed due to cold weather. The symptoms of three patients had developed while receiving treatment, while four patients were admitted to emergency service after oxaliplatin infusion. The physical examinations revealed no pathological findings of the allergic reaction at presentation or during follow-up skin. Patients were monitored and nasal oxygen therapy was administered. A 5 mg intravenous infusion was given for anxiety symptoms in three patients. Patients were discharged after 4 hours of follow-up with resolution of all symptoms Conclusion Laryngopharyngeal dysesthesia should be kept in mind in patients treated with oxaliplatin and presenting with shortness of breath and a feeling of suffocation after cold exposure.
