Hypothesis

Low expression of ECAD leads to reduced tumour cell to tumour cell adhesion and therefore easier disintegration of single tumour cells with increased risk of occult metastatic disease.

Conclusion

Loss of E-cadherin expression is associated with increased lymph node metastasis in head and neck squamous cell carcinoma.

Supporting Evidence

  • E-Cadherin expression was significantly correlated with lymph node status.
  • High E-Cadherin expression was associated with negative lymph node status.
  • The study included a well-defined cohort of patients with early-stage cancers.

Takeaway

This study found that when cancer cells have less E-Cadherin, they are more likely to spread to nearby lymph nodes.

Methodology

E-Cadherin expression was evaluated in tumor tissue of 120 patients using tissue microarray technique and correlated with lymph node status.

Limitations

The study was retrospective and had a limited number of patients with sufficient material for analysis.

Participant Demographics

Mean age was 59 years, with a male to female ratio of 82:38.
