    Abstract: Patients with thin melanoma (≤ 1.0 mm) and melanoma in situ (MIS) represent the majority of newly diagnosed melanoma. We estimated the impact of expert review of outside pathology material on the staging and thus treatment decisions affecting patients referred to a multidisciplinary clinic with early-stage melanoma. Patients and Methods We studied patients with a diagnosis of thin melanoma or MIS referred to H. Lee Moffitt Cancer Center from 2006 to 2009. After comparing the referring laboratory and in-house dermatopathologic interpretations, we calculated any differences in diagnosis and tumor staging and the potential impact of differences in diagnosis and staging on prognosis and surgical treatment using the National Comprehensive Cancer Network clinical guidelines. Results The overall pathologic discordance rate in diagnosis was 4% (15 of 420 patients; 95% CI, 2% to 6%). The overall change in tumor staging rate was 24% (97 of 405 patients; 95% CI, 20% to 28%). Pathology review led to changes in surgical excision margins in 12% of patients (52 of 420 patients; 95% CI, 9% to 16%) and in the decision about whether to perform a sentinel lymph node biopsy in 16% of patients (67 of 420 patients; 95% CI, 13% to 20%). Key pathologic factors, particularly mitotic rate, were frequently missing from outside pathology reports. Conclusion Our data suggest that review of thin melanoma or MIS by an expert dermatopathologist results in frequent, clinically meaningful alterations in diagnosis, staging, prognosis, and surgical treatment. Referral of these patients to a multidisciplinary melanoma clinic is appropriate, and management of such patients should include review of the biopsy whenever feasible.

    Abstract: Indications for sentinel lymph node biopsy (SLNB) for thin melanoma are continually evolving. We present a large multi-institutional study to determine factors predictive of sentinel lymph node (SLN) metastasis in thin melanoma. Patients and Methods Retrospective review of the Sentinel Lymph Node Working Group database from 1994 to 2012 identified 1,250 patients who had an SLNB and thin melanomas (≤ 1 mm). Clinicopathologic characteristics were correlated with SLN status and outcome. Results SLN metastases were detected in 65 (5.2%) of 1,250 patients. On univariable analysis, rates of Breslow thickness ≥ 0.75 mm, Clark level ≥ IV, ulceration, and absence of regression differed significantly between positive and negative SLN groups (all P 〈 .05). These four variables and mitotic rate were used in multivariable analysis, which demonstrated that Breslow thickness ≥ 0.75 mm (P = .03), Clark level ≥ IV (P = .05), and ulceration (P = .01) significantly predicted SLN metastasis with 6.3%, 7.0%, and 11.6% of the patients with these respective characteristics having SLN disease. Melanomas 〈 0.75 mm had positive SLN rates of 〈 5% regardless of Clark level and ulceration status. Median follow-up was 2.6 years. Melanoma-specific survival was significantly worse for patients with positive versus negative SLNs (P = .001). Conclusion Breslow thickness ≥ 0.75 mm, Clark level ≥ IV, and ulceration significantly predict SLN disease in thin melanoma. Most SLN metastases (86.2%) occur in melanomas ≥ 0.75 mm, with 6.3% of these patients having SLN disease, whereas in melanomas 〈 0.75 mm, SLN metastasis rates are 〈 5%. By using a 5% metastasis risk threshold, SLNB is indicated for melanomas ≥ 0.75 mm, but further study is needed to define indications for SLNB in melanomas 〈 0.75 mm.
