[Distribution of cervical metastases from carcinoma of the cervicofacial region].
The primary goal in the therapy of patients with cervico-facial cancers has been always the control of loco-regional disease. It is more difficult to control metastasis than primary tumor. According to numerous authors, metastases to cervical lymphonodus reduce the survival of patients with planocellular cancer of the upper aero-digestive pathways for about 50%. Precise classification of primary tumor and regional lymphonodus is highly significant for adequate and timely treatment of patients with cancers of cervico-facial region. The objective of our study was to make clinical classification of cervico-facial tumors and to establish the distribution of nodes according to node groups and cervical levels. In our series of 319 subjects, T2 category of primary tumors was most prevalent accounting for 40.44%. Clinically palpable lymphonodes were found in 87.15%, with most prevalent N1 category accounting for 42.95%. The incidence of clinically negative cervical nodus (N0) was reported in 12.85%. The nodes of the upper, medium and lower jugular group were most frequent in cancers of the larynx and pharynx. In cancer of the oral cavity, submental and submandibular nodes were the most commonly involved. In distribution of nodes based on oncological cervical levels, 45.86% of nodes at level II of the neck were found in laryngeal cancer, while 40% the neck level I was involved in the cancer of the oral cavity. In epipharyngeal cancer, 3.15% of cervical metastases were detected in the posterior triangle of the neck. The incidence of cervical metastases in specific primary localizations has a significant role for indications of one of the dissections of the neck.
