Predictive Value of Sentinel Lymph Node Biopsy in Cutaneous Squamous Cell Carcinoma Based on the AJCC-8 and Brigham and Women's Hospital Staging Criteria BACKGROUND Recommendations on when to perform sentinel lymph node (SLN) biopsy in cutaneous squamous cell carcinoma (cSCC) are lacking despite the tumor's clear predilection for lymphatic spread. OBJECTIVE To analyze the frequency of SLN metastasis in published series of cSCC in the context of the eighth edition of the American joint Committee on Cancer (AJCC-8) and the Brigham and Women's Hospital (BWH) staging criteria. METHODS Systematic review of studies of patients with cSCC who underwent SLN biopsy that described biopsy results. RESULTS In total, 153 patients with 24 positive SLN biopsies (15.7%) were included. Based on the AJCC-8 criteria positivity rates in the T2 and T3 categories were 8.3% (1/12 patients) and 25% (8/32), respectively. Using the BWH system there were, 2/33 in category T2a (6.5%), and 5/17 in category T2b (29.8%). On applying the same criteria to tumors of the trunk and extremities the results were similar. CONCLUSION It would seem reasonable to recommend SLN biopsy for patients with AJCC-8 Stage T3+ disease or BWH Stage T2b/T3 disease. Both the AJCC-8 and the BWH systems would appear to be useful for staging cSCC of the trunk and extremities.

1550-nm Nonablative Fractional Laser Versus 10,600-nm Ablative Fractional Laser in the Treatment of Surgical and Traumatic Scars: A Comparison Study on Efficacy and Treatment Regimen BACKGROUND The appearance and symptoms of scars can cause significant distress to patients. OBJECTIVE To assess and compare efficacy of the 1,500-nm nonablative fractional laser (NAFL) and 10,600-nm ablative fractional laser (AFL) in reducing symptoms and improving the appearance of traumatic or surgical scars. MATERIALS AND METHODS Single-center prospective, randomized, blinded, split-scar study was conducted on 100 patients with a scar obtained through trauma or surgery. Three treatments of NAFL or AFL were administered to each half of the scar at 4-week intervals. Scars were self-rated by the patient using the Patient and Observer Scar Assessment Scale and a satisfaction score and objectively evaluated by blinded dermatologists using the Manchester Scar Scale and visual analog scale. RESULTS Blinded observers found no statistically significant difference in scar appearance. Patient rating showed improvement of scar appearance (p < .0001). Pain was worse after treatment with AFL (p = .0492). Overall, there was no statistically significant evidence of one laser being superior or inferior to the other for patient and blinded observer scores (p = .3173 and p = .2513, respectively). CONCLUSION Scar treatment with AFL or NAFL is associated with high patient satisfaction. Objective evaluation of scars did not identify improvement in scar appearance.
