PP129 Health Technology Assessment Adaptation: Pharyngolaryngeal Biopsies (OLB) For People with Suspected Head and Neck Cancer in the Outpatient Setting

Abstract

Introduction

In the UK over 12,400 yearly cases of head and neck cancers are reported (2021). Pharyngolaryngeal biopsies (OLB) may improve the speed of diagnosis and treatment of head and neck cancers under local anesthetic. The Scottish Health Technologies Group (SHTG) published advice on this technology in 2018. Since this, additional evidence has been published to warrant a health technology assessment (HTA) for Wales. The aim of this review was to provide update on the clinical and cost-effectiveness of OLB when compared to undergoing biopsy in an operating theatre (OTB) under general anesthetic to inform decision making in Wales.

Methods

A rapid review was undertaken of relevant databases since 2018 of the clinical evidence, health economics and patient perspectives relevant to Wales. Health Technology Wales (HTW) developed a de-novo cost-utility analysis comparing OLB to OTB over a lifetime horizon. Inputs were sourced from the SHTG budget impact analysis, updated with values more relevant to a Welsh setting.

Results

From consultation to biopsy procedure, the mean number of days was 1.3 for OLB compared to 17.4 days under OTB (p < 0.05). The mean time from consultation to start of treatment was 27 days for OLB compared to 41.5 days for OTB (p < 0.05). The economic analysis found a resulting ICER of GBP21,011 (EUR23,824.23) in a population with 2,183 at risk patients. As OLB was associated with lower costs (GBP816 per person) (EUR925.26) and fewer quality adjusted life years than OTB (-0.04), this ICER corresponds to OLB being considered a cost-effective diagnostic strategy.

Conclusions

HTW guidance was able to recommend use of OLB within the diagnostic pathway for head and neck cancers within Wales. For people with a positive test, OLB is sufficient to confirm a diagnosis but should not be used to rule out a diagnosis due to the potential in reducing the time to diagnosis and treatment in a cost-saving way.
