3.4. Indications and Contradictions
All the studies involved in this review have explicitly reported that
patients were diagnosed with LP or RRP, which was confirmed by their
pathological specimens and treated with CO2 laser/KTP
laser excision. On the other hand, contradictions varied from study to
study. Patients treated with adjunctive therapies, such as the HPV
vaccine, were excluded from this study. In addition, serious cases with
systemic metastases, such as lung, were also excluded. Moreover,
patients were treated with not only CO2 laser/KTP laser
but also with other techniques at the same time point, such as PDL laser
and microblade excision, were no involved. The age and gender were not
limited to a specific scope.
