Clinical palpation demonstrated a sensitivity of 66.7% and specificity of 96.6%, while ultrasonography showed a sensitivity of 87.9% and specificity of 97.7%. The combination of ultrasonography and palpation increased the sensitivity to 93.9%, with specificity remaining high at 95.4%. In patients with negative palpation results, comparison of clinicopathological characteristics between metastatic and non-metastatic tumours revealed significant differences in American Joint Committee on Cancer (AJCC) T stage (p=0.001), tumour differentiation (p=0.046) and lymphovascular invasion (p=0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We found that the combination of ultrasonography and palpation is an effective initial screening method, with a sensitivity of 93.9% and a specificity of 95.4%.
