Musy MD Abstract Objective To evaluate the clinical outcomes of a standardized treatment approach for sinonasal undifferentiated carcinoma (SNUC). Study Design Single-center, retrospective case series. Methods Fifteen patients with newly diagnosed SNUC were seen in the Department of Otolaryngology-Head and Neck Surgery at the University of Virginia from 1991 to 2000. Long-term follow-up on five additional patients diagnosed between 1986 and 1991 was also analyzed. Results Overall, 10 patients were treated with curative intent with neoadjuvant chemoradiotherapy followed by craniofacial resection (CFR). The majority of the remainder was treated with palliative radiotherapy or chemoradiotherapy alone. Four patients who underwent CFR are currently free of disease at 4, 36, 49, and 164 months postoperatively. The 2-year survival of all evaluable patients, regardless of treatment, was 47%. Two-year survival was 64% in the group treated by CFR and 25% in the group treated with chemo- and/or radiotherapy (P = .076). Conclusion For patients with good performance status and limited intracranial or intraorbital disease, we continue to advocate initial chemoradiotherapy followed by craniofacial resection. Patients who are deemed inoperable as a result of advanced disease may nevertheless experience significant palliation with chemoradiotherapy only.

Skull base tumors are rare neoplasms and the cytogenetic data on these tumors are limited. The authors cytogenetically analyzed a large series of tumors and compared the findings with patients' pathologic data. Methods. The karyotypes of pathologically confirmed samples of 101 patients, who were operated for oncological extirpation of tumors, were analyzed using G-banding and spectral-karyotyping techniques. Results. Of the 67 malignant tumors, 32 (48%) had chromosomal aberrations, some with complex numerical and structural chromosomal anomalies. Recurrent chromosomal breakpoints were identified in squamous cell carcinomas, adenoid cystic carcinomas (ACCs), sinonasal undifferentiated carcinomas, chordomas, and sarcomas. Specific breakpoints established the diagnosis of various soft tissue sarcomas. Novel chromosomal aberrations were found in various other malignant and benign tumors. Conclusion. This study highlights the value of cytogenetic analysis for diagnosis of skull base tumors. The data add further information on the biological behavior of these rare neoplasms. © 2007 Wiley Periodicals, Inc. Head Neck, 2008 [source] |
