Abstract:
Objective:To observe the morphologic changes of cancer tissues and cells and clinical effect of microwave coagulation therapy (MCT) on oral squamous cell carcinoma.(OSCC), and then to evaluate the possibility of MCT in OSCC treatment.Methods:Forty OSCC patients were involved. MCT was adopted to the treatment of tumor primary focus, and associated with chemotherapy and lymphadenectomy of suprahyoid region or therapeutic neck dissection. After MCT the tissues were extracted for pathological examination immediately and morphologically observated by transmission electron microscope(TEM). All patients were received follow-up investigation for 3 years. The therapeutic effects of the two groups were observed and compared.Results:After MCT, the tissues of primary focus showed degenerative and necrotic tissue, inflammatory granulation, exudative necrosis, hyperplasia or atypical hyperplasia under light microscope. Apoptosis and mastocytes were observed besides the primary focus through TEM. Additionally MCT could protect oral faction, facies and improve survival quality and control local recurrence, which was more advanced than other old method (P
