[Adenocarcinoma of the ethmoid sinus in woodworkers. Retrospective study of 25 cases].
A retrospective oncological study was performed in 25 woodworkers, in whom an adenocarcinoma of the ethmoid sinuses was discovered between March 1985 and December 1993. All patients were males with a mean age of 57 years, and a mean duration of wood dust exposure of 24 years. Signs of nasal obstruction, drainage, and discomfort were present in all cases. Ophthalmological findings were a poor prognosis indicator. It was possible to precisely evaluate treatment and outcome in 23 cases. The majority of tumors were classified as T3 or T4 (72%), with extension beyond the ethmoid sinuses; all were in contact with the roof of the ethmoidal sinuses. Extension was predominantly into the orbital and intracranial cavities as compared with extension posteriorly or into the maxillary sinuses. Treatment was identical in the 25 patients: a) combined surgery including a paranasal and a neurosurgical approach, b) postoperative radiotherapy. Results were expressed in terms of morbidity related to surgery and the oncologic outcome. Operative morbidity and mortality were substantially reduced with reconstruction of the roof of the ethmoidal sinuses. Meticulous excision, in addition to postoperative radiotherapy, resulted in a decreased rate of local recurrence (26%). On the other hand, metastasis were encountered more frequently (30%). Radiotherapy was insufficient when macroscopic excision was incomplete. Chemotherapy was used as palliative treatment in the event of a recurrence and/or metastases. Survival rate was 68% at 3 years, and 48% at 5 years. Most complications and recurrences arose within the first two years. Exophthalmos, intracranial extension, incompleteremoval, and extensive class T4 tumors were associated with a poor prognosis. Optimal therapy for malignant tumors of the ethmoid sinuses requires combined transfacial and neurosurgical approaches that allow precise assessment of tumor extension and adequate excision, yielding an improved oncologic outcome. Followed by radiotherapy, this association can result in a remission. Patient prognosis depends essentially on management of the initial lesion.
