Prognostic analysis of CO₂ laser surgery for early glottic cancer with anterior commissure involvement / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To systematically analyze the local recurrence of CO₂ laser surgery for early glottic cancer and without anterior commissure involvement.@*METHOD@#By searching CBM, CNKI, wanfang, weipu, PubMed, Embase, OVID, and Springer database, the retrospective clinical studies were included according to inclusion and exclusion criteria. Meta analysis of extracted data was carried out by RevMan 5.0 software.@*RESULT@#By analyzing the 1900 cases from 14 retrospective studies using Meta analysis, it was indicated that local recurrence rate of AC+ group was significantly higher than that of AC- group [OR = 3.00, 95% CI (2.31, 3.89), P < 0.01] for early glottic cancer. Local recurrence rates between AC+ group and AC- group for glottic cancer of Tis and T₁b stage showed no statistically significant difference, while those for glottic cancer of T₁a and T₂ stage showed statistically significant difference.@*CONCUSION@#Local recurrence rate of CO₂laser surgery for early glottic cancer was related with anterior commissure involvement.
