Abstract:
OBJECTIVETo analyse the correlation between the micrometastasis and early recurrence and prognosis in laryngeal cancer.
METHODSTotal of 126 patients with laryngeal squamous cell carcinoma were included in the study. The micrometastasis was detected with hematoxylin and eosin staining (HE) and immunohistochemical staining for cytokeratin (CK) of the lymph node specimens after selective neck dissection (II-IV). Chi-square test was used to analyse the relationship between the micrometastasis and early recurrence and prognosis, and Kaplan-Meier method was used for survival analysis.
RESULTSHE staining showed positive micrometastasis in 41 cases and negative micrometastasis in 85 cases in which 33 cases were positive staining for CK. With a following-up of mean 6.3 years, recurrence or metastasis occurred in 15 cases with positive micrometastasis detected by HE staining, 14 cases with CK positive staining and 4 cases with CK negative staining. The correlation between micrometastasis and early recurrence was significant (P < 0.01). The total 5-year survival rate was 79.8%, 10-year survival rate was 60.5%. The 10-year survival rate (52.1%) of the patients with CK positive staining indicating micrometastasis was significantly higher than that of CK negative patients (81.2%, P < 0.01).
CONCLUSIONCervical micrometastasis predicts poor prognosis and early recurrence in patients with laryngeal squamous cell carcinoma.
