Is surgical debridement and topical 5 fluorouracil the optimum treatment for woodworkers' adenocarcinoma of the ethmoid sinuses? A case-controlled study of a 20-year experience.

OBJECTIVES

Woodworkers' adenocarcinoma of the ethmoid sinuses is an extremely rare occupational malignancy with a locally aggressive course. Treatment with surgical exenteration and topical 5 fluorouracil (5FU) packs has become standard treatment over the last 10 years in this ENT unit. This study presents level 2 evidence that 5FU provides improved survival over previous management with primary radiotherapy and salvage craniofacial resection.

DESIGN

Retrospective case series with historical control group.

SETTING

District General Hospital.

PARTICIPANTS

The records of 31 consecutive patients with the disease were analysed. Five patients died prior to treatment. One patient was treated with surgery alone and therefore excluded. Twenty-five patients were included in the analysis. Fourteen were treated with primary radiotherapy and 11 with surgery and topical 5FU.

OUTCOME MEASURES

Disease free survival was measured using Kaplan-Meier survival analysis.

RESULTS

Five-year disease free survival improved from 50% with primary radiotherapy to 86% with surgery and 5FU. This improvement is statistically significant (P = 0.03).

CONCLUSION

Topical 5FU treatment improves survival of Woodworker's adenocarcinoma of the ethmoid sinuses. This finding may be useful in the treatment of other locally aggressive sinonasal malignancies.
