[Early characters of recurred vocal cord cancers after laser cordectomy and treatment].
OBJECTIVE
To explore the characters of recurred vocal cord cancer in early phase after laser cordectomy and selection of the second treatment.


METHODS
Five cases who had recurrence after laser cordectomy was selected and analyzed according to the scope of the tumor, operation type, recurrence time, site of recurrence.


RESULTS
One case's had the first recurrence two months after the first operation and was treated by laser once more, and the second recurrence happened three months after the second operation and no recurrence was found within the 4 years after the third operation-extended vertical hemilaryngectomy. Two cases had recurrence 3 months after the first operation and one case 6 months later. The three cases had extended vertical hemilaryngectomy for remedy and had no recurrence within 4 years. The last one had recurrence 1 year after operation, and received a total laryngectomy. The site of recurrence was the anterior commission in 4 cases and median part of vocal cord in one case. The 5 cases included 3 T1a and 2 T1b. The recurrence rate of T1a and T1b were 3.1% and 50.0% respectively.


CONCLUSIONS
The recurrence time after laser cordectomy is often within half a year. The most common site of recurrence is anterior commission. Extended partial laryngectomy should be the first choice remedy. Strict selection of indication and skillful technique are the base of good efficacy.
