Summary

Panendoscopy is crucial for evaluating head and neck cancer patients for synchronous tumors. While hypopharyngeal endoscopy is beneficial, routine esophagoscopy and bronchoscopy yield limited results for detecting additional malignancies.

Area of Science:

  • Oncology
  • Otolaryngology
  • Gastroenterology

Background:

  • Head and neck squamous cell carcinoma (HNSCC) evaluation requires assessing the entire upper aerodigestive tract.
  • The diagnostic value of panendoscopy (laryngoscopy, bronchoscopy, esophagoscopy) in HNSCC staging remains debated.

Purpose of the Study:

  • To prospectively evaluate the necessity and yield of panendoscopy in staging previously untreated HNSCC patients.
  • To determine the effectiveness of specific endoscopic procedures in detecting synchronous upper aerodigestive tract malignancies.

Main Methods:

  • Prospective analysis of 208 HNSCC patients between January 1984 and December 1985.
  • Standard head and neck examination, chest radiograph, barium esophagram, and panendoscopy were performed.
  • Synchronous malignancies were identified and correlated with diagnostic methods.

Main Results:

  • Fifteen patients (7.2%) presented with synchronous upper aerodigestive tract malignancies.
  • Endoscopy alone detected four (1.9%) synchronous primary tumors.
  • Hypopharyngeal cancers were found in three patients (1.4%); bronchial cancer in one (0.5%) via bronchoscopy. Esophagoscopy yielded no unique findings compared to barium esophagram.

Conclusions:

  • Endoscopic examination of the hypopharynx is valuable for screening additional tumors in HNSCC patients.
  • Routine esophagoscopy is not supported due to lack of unique diagnostic yield.
  • Screening bronchoscopy has a very low yield and cannot be strongly supported for HNSCC evaluation.
