[Simultaneous squamous cell carcinomas of the oral cavity and oropharynx].
BACKGROUND
Squamous cell carcinoma of the oral cavity is often a single localization, but the discovery of another or several associated lesions is not exceptional. The goal of our study was a retrospective analysis of patients having 2 simultaneous squamous cell carcinomas of the upper aerodigestive tract (UADT), i.e. diagnosed during the same panendoscopy by excluding the esophagus and the lung.


METHODS
Between 1995 and 2001, 1,129 patients were treated for squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx in the Bordeaux Maxillo-facial Surgery Unit. 1% of these patients presented 2 simultaneous squamous cell carcinomas of UADT.


RESULTS
Our series was divided in 9 men (75%) and 3 women (25%) with an average age of 61.3 years (48-86). At the end of the study 2 patients were lost to follow-up, 3 patients were alive without recurrence, and 1 patient was alive with recurrence. The average follow-up time was 17.6 months.


CONCLUSIONS
A review of the literature gave an incidence of simultaneous squamous cell carcinomas of UADT varying from 1.3 to 12.8% according to authors. Thus, any patient having squamous cell carcinoma of the UADT must be considered as having an important potential risk to present another simultaneous cancer and to benefit from a systematic panendoscopy. In spite of an early diagnosis, the prognostic of these lesions remains bad.
