Acoustic screening for laryngeal cancer

Area of Science:

• Otolaryngology
• Speech-language pathology
• Biomedical acoustics

Background:

• Early detection of laryngeal cancer is crucial for effective treatment.
• Current diagnostic methods can be invasive or require specialized equipment.
• There is a need for accessible and non-invasive screening tools.

Purpose of the Study:

• To investigate the efficacy of an acoustic screening method for laryngeal cancer detection.
• To identify key acoustic parameters indicative of laryngeal cancer.
• To assess the potential for developing an automated acoustic screening system.

Main Methods:

• Voice samples of sustained vowel 'e' were collected from 64 healthy individuals and 57 laryngeal cancer patients.
• Three acoustic parameters were measured: pitch-period perturbation, peak-amplitude sequence perturbation, and vocal noise.
• Statistical analyses were performed to discriminate between normal and cancer groups.

Main Results:

• The combined analysis of the three acoustic parameters demonstrated significant differences between normal and laryngeal cancer groups.
• Specific patterns of vocal perturbation and noise were identified as potential biomarkers for laryngeal cancer.
• The perceptual significance of these parameters was evaluated, confirming their relevance.

Conclusions:

• The investigated acoustic parameters hold significant potential for developing a non-invasive screening system for laryngeal cancer.
• This acoustic method could serve as an initial screening tool, facilitating earlier diagnosis and intervention.
• Further research and validation are warranted to implement this system in clinical practice.
