[Efficiency of surgical treatment in patients with laryngeal cancer in four clinical centers].

A group of 578 patients with larynx cancer underwent surgical treatment in four Otolaryngological Clinics of Medical Universities in Poznań, Warsaw, Cracow and Lublin between 1986-1987. Within this group, 75% of operated patients had a three--year survival rate without symptoms, and 58% of patients had a five-year survival rate. A detailed evaluation of causes of failures in surgical treatment dealt with e.g. the initial placement of the cancer including entrance margins of larynx in a rich net of lymphatic vessels, extensiveness of organs, the degree of clinical progressions, general physical condition of a patient, radicality of treatment, regularity of check-ups after the operation, high degree of histological malignancy unfavourable configuration of TNM feature blood transfusions, the appearance of remote metastases low efficiency in the early diagnostics of larynx cancer, subjective conditions of patients, discontinuation of complementary irradiation.
