[Significance of angiogenesis in laryngeal cancer].
Angiogenesis as multistage process, which is required for forming of new vessels and is essential for the growth of solid tumors and making metastasis. Sixty patients with laryngeal cancer were analyzed. They were treated in ENT Department of Medical University in Lodz and follow-up period was not shorter than 5 years. Intensity of neovascularisation was examined by means of immunohistochemical techniques carried out on paraffin sections using selected antibody against antigens of vessel cells. The value of the prognostic factors of angiogenesis intensity were evaluated against: dissected nodal metastasis, tumor recurrences and metastasis observed in prospective follow-up and after cancer treatment live time. Morphological properities of tumor or hospital treatment of the patients with laryngeal cancer were analyzed as well. Taking into consideration the results, we can make the conclusion that investigation of angiogenesis can be forthcoming prognostic factor for the laryngeal cancer.
