Abstract

Introduction: Basal cell carcinoma (BCC) is the most common form of skin cancer, predominantly affecting the head and neck, and can be diagnosed clinically in most cases. Metastasis of BCC is rare, but localised tissue invasion and destruction can lead to morbidity. Incidence of BCC increases markedly after the age of 40 years, but incidence in younger people is rising, possibly as a result of increased sun exposure.

Methods and outcomes: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions on treatment response/recurrence (within 1 year of therapy) in people with basal cell carcinoma? What are the effects of interventions on long-term recurrence (a minimum of 2 years after treatment) in people with basal cell carcinoma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2009 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

Results: We found 16 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

Conclusions: In this systematic review we present information relating to the effectiveness and safety of the following interventions: cryotherapy/cryosurgery, curettage and cautery/electrodesiccation, fluorouracil, imiquimod 5% cream, photodynamic therapy, and surgery (conventional or Mohs' micrographic surgery).
