Objectives:
We evaluated the partial surgical management and survival rates in
patients who were treated for early glottic cancers.
Methods: A retrospective study of
therapeutic outcomes was performed on 48 patients with Tis-T1 T2/N0
cancers of the glottic laryngeal carcinoma, treated by partial surgery,
from 1998 to 2004. Surgical techniques were employed in view of factors
such as involvement of anterior commissure and tumor stages.
Decannulation time, swallowing time, survival rates, complications and
outcomes were evaluated.
Results: Four patients (8.3%) with
Tis, 25 (52.1%) with T1a, 9 (18.8%) with T1b, 10 (%20.8) with T2 tumors
were followed up. Surgical techniques were included stripping (n=4,
8.3%), cordectomy (n=14, 29.4%), horizontal glottectomy (n=1, 2.1%),
vertical partial laryngectomy (n=10,20.8%), frontolateral partial
laryngectomy (n=17, 35.4%), supracricoid partial laryngectomy (n=2;
4.2%). Postoperatively positive surgical margin was reported in 5
(10.4%) patients. Three of 5 patients with positive margins developed
recurrences. These patients were treated with postoperative radiotherapy.
One patient without positive margins developed regional recurrence,
treated by unilateral neck dissection and postoperative radiotherapy.
The 3-year overall survivals were 96.9% for T1, 90.5% for Tis, T1 and
T2. Conclusion:
Surgical treatment provides excellent local control and laryngeal
preservation in early glottic cancers. The choice of treatment should be
patient spesific and based on a careful analysis of the factors involved
in each case. |
