Nonetheless, on analyzing margin clearance by specialty and histologic subtype, we still found that dermatologists had a lower rate of margin positivity even for these infiltrative-morpheaform tumors (13.6% for dermatologists, 32.1% for plastic surgeons, 56.3% for general surgeons, and 46.7% for others) (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>).</p><p id="par0130" class="elsevierStylePara elsevierViewall">An interesting finding was the smaller amount of excised tissue in the group of tumors with positive margins, in which the median diameter was 15<span class="elsevierStyleHsp" style=""></span>mm, as opposed to 17<span class="elsevierStyleHsp" style=""></span>mm in the group of complete excisions (<span class="elsevierStyleItalic">P</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>.006). This difference may have arisen as a result of operators’ attempts to take smaller margins to preserve as much normal peritumoral skin as possible, especially if we consider that 80.9% of the tumors with positive margins were taken from the face.</p><p id="par0135" class="elsevierStylePara elsevierViewall">Statistical analysis showed that these between-group differences in the prevalence of positive margin status were unrelated to variables that might potentially make tumor excision difficult, such as a complicated location (face), more aggressive histologic subtype (infiltrative-morpheaform BCCs), larger size, or older patient age (associated with more concomitant diseases).</p><p id="par0140" class="elsevierStylePara elsevierViewall">Dermatologists and nondermatologists treated patients of significantly different ages (median ages, 73 years and 75 years, respectively).

The approach to take when there are positive margins is hotly debated. Conservative management may be reasonable when margins are positive after BCC excision in some cases (for example, when the tumor was not in a high-risk location, when tumor classification indicates low aggressivity, when the positive margins are the lateral ones, and/or when the patient is of advanced age and has concomitant conditions). However, many cases call for further treatment, whether surgical or not (for example, adjuvant radiotherapy).</p><p id="par0150" class="elsevierStylePara elsevierViewall">This study has several limitations. First, the retrospective collection of data meant that certain information, such as tumor diameter, was unavailable in many cases. Therefore, we analyzed the maximum diameter of the excised tissue as a surrogate for tumor size. These measurements, however, may be underestimated given that tissue contracts when stored in a formaldehyde solution. Another source of bias affects the total number of superficial BCCs, given that this type of tumor is often treated with cryotherapy, topical imiquimod, or other procedures. We also do not know if the excised tumors were primary or recurrent lesions. However, even though recurring lesions are surgically more complicated, we think that the lack of this information did not bias the results because in our practice setting the physician who first attends the patient is usually the one who also follows the case and performs later procedures. Finally, we had no information on whether the surgical approach was chosen on the basis of a clinical diagnosis or the analysis of a biopsy specimen. Knowledge of histologic classification can affect the surgeon's estimate of how much margin should be taken when removing a tumor, thus influencing whether the excision is complete or not.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Our study shows that positive-margin rates are lower in BCC excisions performed by surgeons in the dermatology department of Hospital Universitari Vall d’Hebron in comparison with operators who are plastic or general surgeons in the hospital. Factors such as patient age, tumor location and size or histologic subtype do not explain the higher positive-margin rates for nondermatologist surgeons. We believe that dermatologists’ greater ability to reach an accurate clinical diagnosis and skill in identifying tumor margins, which are often hard to discern, as well as their greater knowledge of the biologic behavior of BCCs may explain our findings. When excisions are incomplete, the second procedures that are often required increase health care expenditure and lengthen surgical wait lists. The dermatologist is the specialist who is best able to diagnose and treat skin cancer, as well as the one best equipped to lead multidisciplinary teams when tumors are particularly complicated to remove. Finally, we think it may be necessary to improve aspects of residency training in disciplines in which surgical procedures are performed on the skin.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Conflicts of Interest</span><p id="par0160" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflicts of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:11 [ 0 => array:2 [ "identificador" => "xres97866" "titulo" => array:6 [ 0 => "Abstract" 1 => "Background" 2 => "Objectives" 3 => "Methods" 4 => "Results" 5 => "Conclusions" ] ] 1 => array:2 [ "identificador" => "xpalclavsec85023" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xres97867" "titulo" => array:6 [ 0 => "Resumen" 1 => "Introducción" 2 => "Objetivos" 3 => "Métodos" 4 => "Resultados" 5 => "Conclusiones" ] ] 3 => array:2 [ "identificador" => "xpalclavsec85022" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Patients and Methods" "secciones" => array:1 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Statistical Analysis" ] ] ] 6 => array:3 [ "identificador" => "sec0020" "titulo" => "Results" "secciones" => array:3 [ 0 => array:2 [ "identificador" => "sec0025" "titulo" => "Assessment of Surgical Margins in the Series Overall" ] 1 => array:2 [ "identificador" => "sec0030" "titulo" => "Assessment of Margins by Surgeon's Specialty" ] 2 => array:2 [ "identificador" => "sec0035" "titulo" => "Multivariable Logistic Regression Analysis" ] ] ] 7 => array:2 [ "identificador" => "sec0040" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0045" "titulo" => "Conflicts of Interest" ] 9 => array:2 [ "identificador" => "xack35291" "titulo" => "Acknowledgements" ] 10 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2011-11-02" "fechaAceptado" => "2012-06-02" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec85023" "palabras" => array:3 [ 0 => "Basal cell carcinoma" 1 => "Surgery" 2 => "Positive margins" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec85022" "palabras" => array:3 [ 0 => "Carcinoma basocelular" 1 => "Cirugía" 2 => "Márgenes afectados" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span class="elsevierStyleSectionTitle">Background</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Complete surgical excision is the most common treatment for basal cell carcinoma (BCC), and this intervention is often performed by surgeons who are not dermatologists (e.g., plastic surgeons, general surgeons, oral and maxillofacial surgeons, ophthalmologists, and otorhinolaryngologists).</p> <span class="elsevierStyleSectionTitle">Objectives</span><p id="spar0010" class="elsevierStyleSimplePara elsevierViewall">To determine positive margin rates in BCCs removed by surgeons from different specialties and to identify clinical and pathologic factors that might explain potential differences between specialties.</p> <span class="elsevierStyleSectionTitle">Methods</span><p id="spar0015" class="elsevierStyleSimplePara elsevierViewall">We retrospectively reviewed the pathology reports of all BCCs diagnosed at Hospital Universitari Vall d’Hebron between January 2009 and March 2001.
