[Evaluation of the causes of lymphatic metastases after surgical treatment of patients with laryngeal cancer]. / Ocena przyczyn powstawania przerzutów do wezlów chlonnych po leczeniu operacyjnym chorych na raka krtani.

During the years 1980-1988 2458 laryngeal cancer patients were operated upon in 4 ENT AM Clinics in Kraków, Poznan, Lublin and Warszawa. 300 (12%) out of them have had the cervical node metastases in 18 months after the surgery. The cause analysis was performed. The primary localizations were in the epiglottic and ++post-cricoid areas. The causes of metastases to the ++lymph nodes were analyzed; the primary epiglottic and ++post-cricoid localization of the tumor, its extensiveness and advanced clinical stage. Twice more often were the nodal metastases stated before the primary treatment, a high degree of histological malignancy, probably insufficient radicality of the surgery and insufficient immunological resistance of the organism were taken in consideration. This group of patients presented a rather high percentage of early unsuccessful results of surgical treatment of the laryngeal cancer; this problem needs further analysis and observations.
