OBJECTIVE: To study the pathologic features of occult lymphatic metastasis in patients with supraglottic carcinoma and its implication in treatment.
METHODS: Serial sections of 153 neck dissection specimens in 100 patients with supraglottic carcinoma were studied under microscope.
RESULTS: Clinically negative nodes had been proved histologically positive in 58 specimens (38%) and 51 occult nodes, size ranged from 0.5 cm to 2.6 cm with average of 1.1 cm. The distribution of metastastic lymph nodes was 1 in level I (2%), 37 in level II (73%), 12 in level III(23%) and 1 in level IV(2%). Among the 51 nodes, 21(41%) were in early stage, 18 (35%) in growth stage, 7(14%) in full stage, 5(10%) were extracapsular.
CONCLUSION: Occult metastasis rate of supraglottic carcinoma is as high as 38%, selective neck dissection is recommended for the surgical treatment of this disease.
