• W2009920810 abstract "This retrospective study was undertaken to assess the clinical features and results of treatment of carcinomas of the ethmoid sinus.The records of 34 patients with ethmoid sinus carcinomas treated with curative intent at the U.T.M.D. Anderson Cancer Center (UTMDACC) between January 1969 and December 1993 were reviewed. The age of the patients ranged from 28 to 73 years with a median of 57 years. There were 28 Whites, four Hispanics, one Black and one Asian. A simple staging based on anatomical criteria was used to describe the extent of the disease. Six patients had T1, 13 patients had T2 and 15 patients had T3 disease. Twenty-one patients were treated with surgery plus radiation and 13 patients were treated with radiotherapy alone; nine patients received adjuvant chemotherapy. Radiation was given at approximately 2 Gy per fraction to total doses of 50 Gy preoperatively, 52-66 Gy (median 60 Gy) postoperatively and 50-70 Gy (median 63 Gy) when no surgery was performed.The actuarial 5-year overall, disease-free and disease-specific survival rates were 55%, 58% and 63%, respectively. The actuarial 5-year local control rate was 71% for the whole group (74% for surgery plus radiation and 64% for radiation alone). Local recurrence occurred in nine patients, nodal relapse occurred in three patients and distant metastases occurred in four patients. Histologically proven dura mater invasion was associated with a poorer local control rate in patients undergoing surgery and radiation. The simple T-staging system used in this study was a good discriminator for local control. Of nine patients receiving chemotherapy, three had complete responses and four had partial responses; six of the seven responders had undifferentiated carcinoma. Severe complications of therapy occurred in patients treated between 1969 and 1984 and consisted mainly of visual impairment and brain necrosis.This retrospective review of a large single institutional experience showed that ethmoid sinus carcinomas have a tendency for extensive local invasion but a low propensity for lymphatic and hematogenous spread. Hence, local recurrence was the main cause of cancer-related death. Combined treatment with surgery and postoperative irradiation yielded the highest local control rate. However, radiotherapy alone eradicated two-thirds of primary tumors and, consequently, is a reasonable alternative treatment for patients with medical contraindications to surgery. For patients who underwent surgery and radiotherapy, the presence of histologically proven dura mater invasion was associated with a higher local recurrence rate. Severe radiation complications have been rare with the contemporary radiotherapy technique. Chemotherapy induced excellent responses in undifferentiated carcinoma but its impact on overall disease control is unclear in this small series of patients." @default.
