Hypothesis
Can more sensitive methods like real-time RT–PCR detect carcinomatous lymph node involvement in head and neck squamous cell carcinoma?
Conclusion
Real-time RT–PCR is a sensitive and reliable method for detecting cancer cells in lymph nodes of patients with head and neck squamous cell carcinoma.
Supporting Evidence
- Real-time RT–PCR detected CK19 mRNA in 36.0% of lymph node levels, while histopathology detected only 16.3%.
- 13 out of 31 patients had a change in nodal status based on real-time RT–PCR results.
- CK19 mRNA expression was significantly higher in histologically positive lymph nodes compared to negative ones.
Takeaway
Doctors can use a special test to find tiny cancer cells in lymph nodes that regular tests might miss, helping to treat patients better.
Methodology
The study evaluated 1328 lymph nodes from 31 patients using routine staining, immunohistochemistry, and real-time RT–PCR to detect CK19 mRNA.
Limitations
The study did not establish the prognostic significance of micrometastases in head and neck squamous cell carcinoma.
Participant Demographics
Patients had primary squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx, with an average age of 59.5 years.
