Dose dependent slurred speech and laryngopharyngeal dysesthesia due to oxaliplatin

Abstract

Introduction

Oxaliplatin is a platinum containing alkylating agent commonly used in the management of colorectal cancers. The most common dose-limiting toxicity of oxaliplatin is peripheral neuropathy, which can be severe enough to cause treatment discontinuation. We present a case of dysarthria and laryngopharyngeal dysesthesia (LPD) that developed during the first dose of oxaliplatin, which showed dose-dependent reduction in severity in subsequent cycles.

Case report

A 52-year-old female patient with adenocarcinoma of rectum (pT4N2M0) was prescribed oxaliplatin (130 mg/m²) and capecitabine(2000mg/m²). She developed heaviness in the tongue, slurred speech, jaw pain, perioral paresthesia within 30 min after the end of 3 h infusion of oxaliplatin in the first cycle. The symptoms subsided without any sequelae in two days. However, in the subsequent cycles as the dose of the oxaliplatin was reduced, similar symptoms reappeared but were of reduced in severity. No dysesthesia symptoms were observed in the 4th cycle when the oxaliplatin was administered at 85 mg/m².

Management and outcome

As and when the patient developed symptoms – slurred speech, jaw pain during the first three cycles, she was managed with inj. Hydrocortisone (100 mg i.v.) and one ampoule of pheniramine (45 mg i.v.).

Discussion

Occurrence of laryngopharyngeal dysesthesia due to oxaliplatin does not warrant drug withdrawal, dose titration can be helpful, thereby preventing the drug withdrawal for the patient management.
