Abstract:

INTRODUCTION: Direct laryngoscopy and biopsy is the gold standard for obtaining a tissue diagnosis in patients with suspected laryngeal cancer. In patients with advanced disease or other medical comorbidities, this may come with significant anaesthetic risks, including tracheostomy. Ultrasonography-guided biopsy has been widely used in the diagnosis of malignancy involving cervical lymph nodes but it is not commonly employed in the diagnosis of laryngeal tumours. A systematic review was undertaken to assess the literature looking at whether ultrasonography-guided transcutaneous fine needle aspiration cytology (FNAC) is an adequate method in diagnosing laryngeal malignancy.

METHODS: Two independent researchers conducted a systematic review of the literature using the MEDLINE and Cochrane Library databases in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines.

RESULTS: A total of 568 studies were identified from the search, of which 3 met the inclusion criteria, resulting in 162 patient episodes. The pooled accuracy of transcutaneous FNAC in acquiring a sample adequate for histological diagnosis was 74.9%. Data on complications were limited, with a few cases of mild haemoptysis being recorded.

CONCLUSIONS: Transcutaneous FNAC can be considered a safe and quick method for establishing a histological diagnosis of laryngeal lesions, particularly in patients who may be severely comorbid, and it could therefore could reduce the risks of general anaesthesia and tracheostomy prior to commencing definitive treatment.
