[The treatment procedure in olfactory (esthesioneurogenic) tumors].

In 1968-1988, eleven cases of olfactory neurogenic tumors were seen at The All-Union Center for Oncology Research, Moscow which made up 9.5% of the total of nasal cavity cancers. Morphologically, esthesioneurocytoma was diagnosed in two patients whereas esthesioneuroblastoma--in nine. Four patients received combined therapy while seven--chemotherapy and radiation. Progression of the disease was registered in 7 out of 11 patients: in 3 of 4 cases receiving combination treatment and in 4 out of 7 those treated conservatively. Four cases died within 7-29 months while 7 remain alive: two patients at 18 and 156 months following combined therapy and 5--at 18, 18, 24, 84 and 132 months after chemoradiation treatment. Radiation alone proved the best therapeutic option. Surgery is justified in cases with residual tumor as second-line procedure.
