BACKGROUNDSurgical excision is the treatment of choice for basal cell carcinoma and
micrographic surgery considered the gold standard, however not yet used
routinely worldwide available, as in Brazil. Considering this, a previously
developed treatment guideline, which the majority of tumors were treated by
conventional technique (not micrographic) was tested.OBJECTIVETo establish the recurrence rate of basal cell carcinomas treated according
to this guideline.METHODBetween May 2001 and July 2012, 919 basal cell carcinoma lesions in 410
patients were treated according to the proposed guideline. Patients were
followed-up and reviewed between September 2013 and February 2014 for
clinical, dermatoscopic and histopathologic detection of possible
recurrences.RESULTSAfter application of exclusion criteria, 520 lesions were studied, with 88.3%
primary and 11.7% recurrent tumors. Histological pattern was indolent in
85.5%, 48.6% were located in high risk areas and 70% small tumors. Only 7.3%
were treated by Mohs micrographic surgery. The recurrence rate, in an
average follow-up period of 4.37 years, was 1.3% for primary and 1.63% for
recurrent tumors. Study limitations: unicenter study, with all patients
operated on by the same surgeon.CONCLUSIONThe treatment guideline utilized seems a helpful guide for surgical treatment
of basal cell carcinoma, especially if micrographic surgery is not
available.
