Abstract:
OBJECTIVE:To analyze the recurrencerelative factors of early glottic carcinoma after carbon dioxide laser treatment.
METHOD:A retrospective analysis of 134 early glottic carcinoma patients' clinical data was taken to analyze the relationships between recurrence and gender, age, pathologic degree, T stage, involvement of anterior commissure and involvement of thyroarytenoid muscle.
RESULT:Recurrent ratio of well-differentiated, middle-differentiated and poorly-differentiated squamous cell carcinoma were 11.83%, 18.42% and 33.33% (P > 0.05) respectively. Recurrent ratio of T1a, T1b, T2 were 13.24%, 18.92%, 23.08% (P > 0.05) respectively. The recurrent rate was 33.33% of tumors offended the anterior commissure, versus 5.43% with no involvement of anterior commissure (P < 0.01). The recurrent rate was 59.09% of tumors offended the thyroarytenoid muscle, versus 5.36% with no involvement of thyroarytenoid muscle (P < 0.01). Unvaried and multivariate analysis indicated that the involvement of anterior commissure and the involvement of thyroarytenoid muscle were the factors of recurrence.
CONCLUSION:Recurrence of early glottic carcinoma after carbon dioxide laser treatment is effected by the involvement of anterior commissure and the involvement of thyroarytenoid muscle. Resection can be performed conservatively according to evaluation of macroscopic tumour extension.
