NED survival in head and neck cancer (post-mortem correlations)
The Journal of Laryngology and Otology
|February 1, 1988
Summary
Patients dying with no evident disease (NED) in head and neck squamous cell carcinoma studies are often considered cured. However, autopsies revealed distant spread in two such cases, challenging current survival statistics.
Area of Science:
- Oncology
- Pathology
- Cancer Research
Background:
- Current head and neck squamous cell carcinoma (HNSCC) reporting often classifies patients dying with no evident disease (NED) as successfully treated.
- This standard practice may overestimate treatment efficacy by overlooking subclinical disease progression.
Observation:
- Two HNSCC patients, initially classified as NED and presumed cured, were found to have significant distant metastases upon post-mortem examination.
- These autopsy findings contradict the clinical assessment of successful treatment.
Findings:
- The study highlights the potential for widespread subclinical metastases in HNSCC patients who appear clinically cured.
- Autopsy data revealed discrepancies between clinical staging and actual disease burden, indicating underdiagnosis of distant spread.
Implications:
- Rethinking the definition of 'successful treatment' in HNSCC clinical trials is necessary.
- Incorporating post-mortem examination rates into survival statistics could provide a more accurate representation of HNSCC outcomes.
- Further research into the prevalence and impact of subclinical metastases in HNSCC is warranted.
