Prognostic criteria of patients’ survival at malignant craniofacial tumors

Abstract

Introduction. Taking into account that malignant tumors often recur, determining prognostically significant criteria makes it possible to improve the treatment strategy, justify the indications for surgery, and to increase the overall patients’ survival. Materials and methods. In a period from 2002 to 2012 treatment results of 133 patients with malignant craniofacial tumors were analyzed. Results. Study of intracranial or sometimes intracerebral spread of malignancies, dura mater invasion or concretion, as well as resection are the basis of prognostic factors in surgery of craniofacial tumors. It was found that the patients’ survival rates did not depend on these factors and the histological type of the tumor. They depend upon such factors as disease duration, patient’s age, tumor invasion, growth of tumor tissue around the eye hole. 3 years survival was 53%, 5 years — 38%. After surgery all patients were alive. Complications occurred in 19 (14%) patients. Conclusion. Accounting for prognostic factors gives an opportunity to increase overall survival rates, to reduce the incidence of postoperative complications, avoid postoperative mortality.
