Electrocoagulation for intraoral cancer
C. S. Whelan, D. E. Marcello Jr, W. B. Patterson and P. J. Deckers
Electrocoagulation of 58 intraoral lesions (1 to 6.5 cm in diameter)
resulted in a three-year absolute disease-free survival rate of 59%
(34/58). During the 20-year study, 43 (74%) of the 58 patients were cured.
Though an initial 28% local failure rate was observed, 31% (5/16) of these
patients were subsequently cured by a second electrocoagulation.
Electrocoagulation has distinct advantages over conventional surgery and
irradiation. Relatively little tissue beyond the tumor is coagulated. Such
tissue sparing allows better postoperative function and cosmesis. The
deleterious effects of irradiation, including the serious "dry-mouth"
syndrome, are avoided. These treatment results are competitive with those
of conventional surgery and irradiation. The limited field treated, the
tissue conservation, the minimal morbidity, and the cost-effectiveness
should make electrocoagulation a real consideration in treating selected
invasive intraoral tumors. Ideally suited for electrocoagulation are those
patients whose lesions are small, easily visualized, mobile, and well
differentiated.
