The median age of participants in the trials that reported age was 64.9 years (range, 20–95 years).

Much of the evidence the reviewers found came from single studies, preventing meta-analysis. Conventional surgical excision continues to be the most effective treatment for low-risk BCC. Most studies had small sample sizes, and some had problems with blinding, limitations which will have affected the assessment of subjective outcomes, such as pain and cosmetic results.

La gran mayoría de la evidencia evaluada proviene de estudios individuales que impidieron la realización de una revisión sistemática cuantitativa. La escisión quirúrgica convencional continúa siendo la terapia más eficaz para el tratamiento de los CBC de bajo riesgo. La mayoría de los estudios incluyeron tamaños de muestra pequeños y algunos tuvieron problemas con el cegamiento, lo que influiría en resultados subjetivos, tales como el dolor o la cosmesis.
