Objectives: We evaluated the surgical techniques
employed and survival rates in patients who were treated
for early glottic cancer.
Patients and Methods: The study included 29 patients (28
males, 1 female; mean age 59 years; range 47 to 73 years)
who underwent surgery for early glottic cancer. Surgical
techniques were employed in view of factors such as
involvement of the anterior commissure, the extent of subor
supraglottic invasion, and cord mobility. Two- and fiveyear
survival rates were calculated. TNM classification was
made according to the 1992 AJCC staging system.
Results: Preoperative tumor stages were TisN0 (n=2, 7%),
T1N0 (n=20, 69%), and T2N0 (n=7, 24%). Surgical techniques
included laryngofissure and cordectomy (n=9, 31%),
frontolateral laryngectomy (n=18, 62%), and vertical hemilaryngectomy
(n=2, 7%). Positive surgical margins were
reported postoperatively in 10 patients, eight of whom
remained tumor-free with (n=4) or without (n=4) radiation
therapy during the follow-up period, while two patients
underwent total laryngectomy because of local recurrences.
Three patients died due to causes other than the primary
disease. Two- and five-year survival rates were 88.8% and
Conclusion: Involvement of the anterior commissure, and
the extent of invasion to the subglottis, supraglottis, and the
laryngeal ventricle seem to play a major role in selecting the
most appropriate surgical technique in early glottic cancer.
