Abstract
BACKGROUND We aimed to develop tools that could predict the occurrence of distant metastases in melanoma and its prognosis based on clinical and pathological characteristics. MATERIALS AND METHODS We obtained data from the Surveillance, Epidemiology, and End Results (SEER) database of melanoma patients diagnosed between 2010 and 2019. Logistic analyses were performed to identify independent risk factors associated with distant metastasis. Additionally, multivariate Cox analyses were conducted to determine independent prognostic factors for patients with distant metastasis. Two nomograms were established and evaluated with the receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Furthermore, we performed a retrospective analysis of melanoma with distant metastasis from our institute between March 2018 and June 2022. RESULTS Of the total 19 396 melanoma patients, 352 (1.8%) had distant metastases at the time of diagnosis. The following clinical and pathological characteristics were identified as independent risk factors for distant metastasis in melanoma: N stage, tumor size, ulceration, mitosis, primary tumor site, and pathological subtype. Furthermore, tumor size, pathological subtype, and radiotherapy were identified as independent prognostic factors. The results of the training and validation cohorts' ROC curves, calibration, DCA, and Kaplan-Meier survival curves demonstrate the effectiveness of the two nomograms. The retrospective study results from our center supported the results from the SEER database. CONCLUSION The clinical and pathological characteristics of melanoma can predict a patient's risk of metastasis and prognosis, and the two nomograms are expected to be effective tools to guide therapy decisions.

Abstract
Age plays a dynamic role in incidence, presentation, and extent of disease for cutaneous melanoma. Even within the spectrum of juvenile melanoma, there exists a range of spitzoid and nonspitzoid melanocytic and melanoma lesions. Spitzoid melanomas, a more favorable disease in juvenile patients, are malignant lesions and require treatment as such. Lymph node metastases in melanoma occur at lower rates in older patients compared with younger counterparts, yet the rate of metastases is still high. Age appears to play an important role in the development and progression of melanoma, and understanding the differences across age populations is important when counseling patients.

Abstract
We aim to find a biomarker that can effectively predict the prognosis of patients with cutaneous melanoma (CM). The RNA sequencing data of CM was downloaded from The Cancer Genome Atlas (TCGA) database and randomly divided into training group and test group. Survival statistical analysis and machine-learning approaches were performed on the RNA sequencing data of CM to develop a prognostic signature. Using univariable Cox proportional hazards regression, random survival forest algorithm, and receiver operating characteristic (ROC) in the training group, the four-mRNA signature including CD276, UQCRFS1, HAPLN3, and PIP4P1 was screened out. The four-mRNA signature could divide patients into low-risk and high-risk groups with different survival outcomes (log-rank p < 0.001). The predictive efficacy of the four-mRNA signature was confirmed in the test group, the whole TCGA group, and the independent GSE65904 (log-rank p < 0.05). The independence of the four-mRNA signature in prognostic prediction was demonstrated by multivariate Cox analysis. ROC and timeROC analyses showed that the efficiency of the signature in survival prediction was better than other clinical variables such as melanoma Clark level and tumor stage. This study highlights that the four-mRNA model could be used as a prognostic signature for CM patients with potential clinical application value.

Abstract
BACKGROUND Melanoma is a leading cause of morbidity and mortality in Australia and New Zealand. New Zealand has the highest melanoma incidence in the world alongside Australia at 54 per 100 000 persons. The aim of this study is to conduct a retrospective quality audit of sentinel lymph nodal biopsy (SLNB) practices from 2007 to 2019 of a high-volume melanoma surgeon. Primary outcome was false negative rate (FNR). Secondary outcomes were sentinel node (SN) identification and removal rate, and complication rates. METHODS A database was maintained, containing n = 553 consecutive SLNB's for cutaneous melanoma from 31 August 2007 to 31 August 2019. Patient characteristics and details of the primary lesion, sentinel lymph node biopsy, recurrence and complications were recorded. RESULTS SN's were successfully identified in 444 (99.6%) out of 446 patients with an FNR of 9.1%. Positive SN's were identified in 70 (12.7%) SLNB's. Complications occurred in 76 out of 553 (13.7%) SLNB's. A review of internationally published literature reveals an SN identification rate of 94.4-99.5% with an FNR of 4.0-37.5%. SLNB is the best staging tool for melanoma and gives potential access to adjuvant systemic treatment if >1 mm deposits are found. It is a day-stay procedure with a low-complication rate. CONCLUSION SLNB is a safe and reliable procedure utilized for cutaneous melanoma. We propose our data should be used alongside international SN series to establish Quality Performance Indicators to improve melanoma management.

Abstract
Objectives: Melanoma induces lymphangiogenesis by secreting lymphangiogenic growth factors. The aim of this study was to examine the role of tumour lymphangiogenesis in survival of patients with cutaneous melanoma. Methods: Immunostaining of one hundred melanoma specimens was done with lymphatic-specific antibody D2-40. The quantification of tumour lymphangiogenesis - lymphatic vessel density (LVD) and lymphatic vessel area (LVA) - was calculated by computer-assisted morphometric analysis. Results: High intratumoural LVD, high peritumoural LVD, male gender, greater tumour thickness and Clark level IV/V were significantly associated with shorter disease-free survival (p= 0.001, p= 0.004, p= 0.004, p= 0.000 and p= 0.008, respectively) and melanoma-specific survival (p= 0.002, p= 0.002, p= 0.001, p= 0.000 and p= 0.017, respectively), while the trunk melanoma site was significantly associated only with shorter disease-free survival (p= 0.033). No significant association of LVA with survival was found. At multivariate analysis, peritumoural LVD [hazard ratio (HR) = 2.143, 95% confidence interval (CI) 1.097-4.189, p= 0.026)] and melanoma thickness (HR = 1.276, 95%CI 1.106-1.473, p= 0.001) were independent predictors of disease-free survival, while intratumoural LVD (HR = 3.446, 95%CI 1.465-8.109, p= 0.005), peritumoural LVD (HR = 2.742, 95%CI 1.313-5.725, p= 0.007) and gender (HR = 2.880, 95%CI 1.304-6.362, p= 0.009) were independent predictors of melanoma-specific survival. Conclusion: Тhis study shows that LVD enables better prediction of survival than melanoma thickness and other clinical-pathological parameters. Intratumoural LVD is the most significant predictor of melanoma-specific survival, while only peritumoural LVD has a significant impact on both, a disease-free survival and a melanoma-specific survival.

Abstract
Sentinel lymph node biopsy (SLNB) is a standard procedure for regional lymph node staging and still has the most important prognostic value for the outcome of patients with thin melanoma. In addition to ulceration, SLNB had to be considered even for a single mitotic figure in thin (<1 mm) melanoma according to AJCC7th guideline, therefore, a retrospective review was conducted involving 403 pT1 melanoma patients. Among them, 152 patients suffered from pT1b ulcerated or mitotic rate ≥ 1/ mm2 melanomas according to the AJCC7th staging system. SLNB was performed in 78 cases, of which nine (11.5%) showed SLN positivity. From them, interestingly, we found a relatively high positive sentinel rate (6/78-8%) in the case of thin primary melanomas ˂0.8 mm. Moreover, the presence of regression increased the probability of sentinel positivity by 5.796 fold. After reassessing pT stage based on the new AJCC8th, 37 pT1b cases were reordered into pT1a category. There was no significant relation between other characteristics examined (age, gender, Breslow, Clark level, and mitosis index) and sentinel node positivity. Based on our data, we suggest that mitotic rate alone is not a sufficiently powerful predictor of SLN status in thin melanomas. If strict histopathological definition criteria are applied, regression might be an additional adverse feature that aids in identifying T1 patients most likely to be SLN-positive. After reassessing of pT1b cases according to AJCC8th regression proved to be independent prognostic factor on sentinel lymph node positivity. Our results propose that sentinel lymph node biopsy might also be considered at patients with regressive thin (˂0.8 mm) melanomas.

Abstract
PURPOSE Based on recent advances in the management of patients with sentinel node (SN)-positive melanoma, we aimed to develop prediction models for recurrence, distant metastasis (DM) and overall mortality (OM). METHODS The derivation cohort consisted of 1080 patients with SN-positive melanoma from nine European Organization for Research and Treatment of Cancer (EORTC) centres. Prognostic factors for recurrence, DM and OM were studied with Cox regression analysis. Significant factors were incorporated in the models. Performance was assessed by discrimination (c-index) and calibration in cross-validation across centres. The models were externally validated using a prospective cohort consisting of 705 German patients with SN-positive: 473 trial participants of the German Dermatologic Cooperative Oncology Group study (DeCOG-SLT) and 232 screened patients. A nomogram was developed for graphical presentation. RESULTS The final model for recurrence and the calibrated models for DM and OM included ulceration, age, SN tumour burden and Breslow thickness. The models showed reasonable calibration. The c-index for the recurrence, DM and OM model was 0.68, 0.70 and 0.70, respectively, and 0.70, 0.72 and 0.74, respectively, in external validation. The EORTC-DeCOG model identified a robust low-risk group, with all identified low-risk patients (approximately 4% of the entire population) having a 5-year recurrence probability of <25% and an overall 5-year recurrence rate of 13%. A model including information on completion lymph node dissection (CLND) showed only marginal improvement in model performance. CONCLUSIONS The EORTC-DeCOG nomogram provides an adequate prognostic tool for patients with SN-positive melanoma, without the need for CLND. It showed consistent results across validation. The nomogram could be used for patient counselling and might aid in adjuvant therapy decision-making.

Abstract
Importance There has been a continued increase in the incidence of newly diagnosed melanomas, most of which are T1 melanomas. The associations between changes in tumor staging, implemented with the 7th edition of the AJCC Cancer Staging Manual (AJCC 7), and sentinel lymph node biopsy rates and nodal positivity rates remain to be seen. Objective To evaluate the change that the implementation of the AJCC 7 had on staging criteria and the distribution of thin melanomas requiring nodal surgery and nodal positivity rates. Design, Setting, and Participants Retrospective cross-sectional study from 2004 through 2013 of all adults (≥18 years) diagnosed with a T1 (Breslow depth ≤1.0 mm) melanoma using The National Cancer Database that captures 70% of all newly diagnosed cancers from accredited Commission on Cancer organizations, including both academic and community settings. Data were analyzed in May 2017. Exposures Patients were grouped together based on year of diagnosis, before and after 2009. Main Outcomes and Measures To determine the sentinel lymph node biopsy rate before and after the implementation of the AJCC 7. Results A total of 141 280 patients met inclusion criteria. Of 86 846 patients diagnosed from 2004 through 2009, 53.7% (49 644) were male and had a mean (SD) age of 57.7 (16.4) years. Of 54 434 patients diagnosed from 2010 through 2013, 54.3% (31 086) were male and had a mean (SD) age of 59.5 (15.9) years. After 2010, there was a 3.8% decrease in the number of nodal surgeries performed (32 485 of 86 846 patients [37.6%] vs 18 379 of 54 434 patients [33.8%]; P < .001). The nodal positivity rate decreased 1.0% from (9.8% [3166 of 86 846] to 8.8% [1618 of 54 434]) (P < .001). An increase in the proportion of T1b melanomas being evaluated, from 48.8% to 62.2%, was seen (P < .001). Of T1b melanomas that underwent nodal evaluation from 2004 through 2009, 74.0% had Clark level IV (invasion of the reticular dermis) or Clark level V (invasion of the deep, subcutaneous tissue) and 9.5% were ulcerated. From 2010 through 2013, of the T1b melanomas undergoing nodal evaluation, 82.6% had an elevated mitotic rate only, 3.7% were ulcerated, and 13.7% had both ulceration and an elevated mitotic rate. Conclusions and Relevance It appears that after the institution of AJCC 7, there was an overall decrease in the number of T1 melanomas undergoing nodal biopsy without a clinically relevant change in sentinel lymph node positivity, with an increase in the number of T1b melanomas undergoing nodal evaluation.

Abstract
We evaluated clinical, phenotypic, behavioral, and histopathologic variables in relationship to melanoma-specific survival by age at diagnosis among 650 population-based melanoma patients in Connecticut, with 20 years of follow-up. Only one variable, skin awareness, was significantly associated with melanoma mortality in both groups. The variables that differed between the age-groups were anatomic site, Breslow thickness, histologic subtype, mitoses, tumor-infiltrating lymphocytes (TILs), and solar elastosis. Head and neck melanoma, Breslow thickness, nodular melanoma, and solar elastosis were all significantly more likely to be associated with mortality among the older subjects; among the younger subjects, the presence of mitoses was associated with an increased probability of dying and TILs were associated with a reduced risk of mortality.

BACKGROUND A proportion of patients develop recurrence following a tumour-negative sentinel lymph node biopsy (SLNB). This study aimed to explore whether melanoma patients with BRAF or NRAS mutant tumours have an increased risk of developing disease recurrence following a negative SLNB compared to patients with wild-type tumours. METHODS Prospective cohort study of melanoma patients at three tertiary referral centres in Melbourne, who underwent SLNB. Clinical, pathological and molecular characteristics and recurrence data were prospectively recorded. Multivariate Cox proportional hazards regression models estimated the adjusted hazard ratio (aHR) and corresponding 95% confidence interval (CI) for the association between mutation status and development of recurrence following a negative-SLNB. RESULTS Overall, 344/477 (72.1%) patients had a negative SLNB. Of these, 54 (15.7%) developed subsequent recurrence. The risk of disease recurrence following a negative SLNB was increased for patients with either a BRAF or NRAS mutant tumour compared to wild-type tumours (aHR 1.92, 95% CI: 1.02-3.60, p = 0.04). CONCLUSION Melanoma patients with BRAF or NRAS mutant tumours had an increased risk compared to patients with BRAF/NRAS wild-type tumours of developing disease recurrence following a tumour-negative SLNB. The findings also confirm the importance of continued surveillance to monitor for disease recurrence among SLNB-negative patients.

Abstract
BACKGROUND Melanoma is a malignant neoplasia that shows high mortality when diagnosed in advanced stages. Early identification of high-risk patients for the development of melanoma metastases is the main strategy to reduce mortality. OBJECTIVE To assess the influence of eight epidemiological and histopathologic features on the development of metastases in patients diagnosed with primary cutaneous melanoma. METHODS Our historical cohort comprised patients with invasive primary cutaneous melanoma seen between 1995 and 2012 at a public university hospital and a private oncologic surgery institution in Southeastern Brazil. The following variables were analyzed: gender, age, family history of melanoma, site of the primary tumor, clinical and histologic subtype, Breslow thickness, histologic ulceration and the mitotic index. Kaplan-Meier univariate test and multivariate Cox proportional hazard analysis were used to assess factors associated with disease-free survival. RESULTS Five hundred and fourteen patients were enrolled. The univariate analysis identified the following significant risk factors: gender, age, site of the tumor, clinical and histologic subtype, Breslow thickness, histologic ulceration and mitotic index. Multivariate analysis included 244 patients and detected four significant prognostic factors: male gender, nodular clinical and histologic subtype, Breslow thickness > 4mm, and histologic ulceration. The mitotic index was not included in this analysis. STUDY LIMITATIONS Small number of patients in multivariate analysis. CONCLUSIONS The following prognostic factors to the development of melanoma metastasis were identified in the study: male gender, nodular histologic subtype, Breslow thickness > 4mm and ulceration.

Abstract
INTRODUCTION In many patients, the clinical behaviour of cutaneous melanoma is very difficult to predict by traditional histologic and clinical parameters. This study aimed to examine the role of quantitative parameters of tumour lymphangiogenesis and vascular endothelial growth factor (VEGF)-C in predicting metastatic risk in patients with cutaneous melanoma. METHODS One hundred melanoma specimens were stained with lymphatic-specific antibody D2-40 and with anti-VEGF-C antibody. Quantitative parameters of lymphangiogenesis-lymphatic vessel density (LVD) and lymphatic vessel area (LVA)-were determined by computer-assisted morphometric analysis. Moderate or strong staining was assessed as a positive expression of VEGF-C in tumour cells. RESULTS Univariate analysis revealed that intratumoural LVD, peritumoural LVD, VEGF-C expression in tumour cells, melanoma thickness, Clark level, ulceration, gender and histologic type were significant predictors of lymph node metastasis (p = 0.000, p = 0.000, p = 0.000, p = 0.000, p = 0.005, p = 0.005, p = 0.011 and p = 0.027, respectively). No significant association of intratumoural and peritumoural LVA with metastases was found. In multivariate analysis, independent predictors of metastatic risks were melanoma thickness [odds ratio OR = 1.655, 95% confidence interval (CI) 1.102-2.484, p = 0.015], intratumoural LVD (OR = 1.086, 95% CI 1.027-1.148, p = 0.004), peritumoural LVD (OR = 1.050, 95% CI 1.008-1.094, p = 0.020) and a positive VEGF-C expression in tumour cells (OR = 20.337, 95% CI 2.579-160.350, p = 0.004). CONCLUSIONS This study identified intratumoural and peritumoural LVD and the VEGF-C expression in tumour cells as more significant predictors of metastatic risk than melanoma thickness, ulceration and other clinical-pathological parameters.

Abstract
Mucosal melanomas represent a rare entity with different risk factors and molecular features compared to cutaneous melanomas. They arise most commonly from mucosal surfaces in the head/neck region, the female genital tract (FGT) and the anorectal region. The aim of this study was to evaluate clinics, prognosis, and treatment options of patients with mucosal melanoma, in particular with regard to different primary sites.We retrospectively analyzed 75 patients with mucosal melanomas diagnosed in the years 1993 to 2015 in our department. The primary melanomas were located in the head/neck region (n = 32), the FGT (n = 24), and the anorectal region (n = 19).The median age of the patients was 66 years. At initial diagnosis the primary melanoma was not completely resectable in 11 (15%) patients, 18 (24%) patients had regional lymph node metastases, and 7 (9%) patients distant metastases. During follow-up, 22 (29%) patients suffered from a local recurrence, in particular patients with primary melanoma in the head/neck region without postoperative radiotherapy. By multivariate analysis location of the primary melanoma in the head/neck area or anorectal region and presence of metastases at time of diagnosis represented poor prognostic factors for recurrence-free survival. In 62 tested individuals 7 KIT mutations were found, 2 BRAF mutations in 57 tested patients. Four patients received targeted therapies, 14 checkpoint inhibitors, 4 (1/1 on vemurafenib, 1/7 on ipilimumab, and 2/7 on PD-1 inhibitors) patients showed responses of more than 100 days duration.Mucosal melanomas are often locally advanced or metastatic at initial diagnosis, thus they require extensive staging procedures. The high rate of local recurrences in the head/neck region can be significantly reduced by postoperative radiotherapy. For the potential use of medical treatment a mutation analysis for KIT and BRAF genes should be performed. The use of new immunologic and targeted therapies has to be further evaluated.

Abstract
Microphthalmia transcription factor (Mitf) is involved in melanocyte development and differentiation. We previously reported that Mitf expression, as detected by immunohistochemical analysis, is an independent prognostic marker in patients with intermediate-thickness melanoma. However, the clinical significance of Mitf expression in melanoma is not well delineated. In this prospective study, we attempted to demonstrate the correlation between Mitf expression in primary melanoma and the sentinel lymph node status and prognosis. We prospectively examined primary cutaneous melanomas from 94 patients undergoing nodal staging by sentinel lymph node biopsy. We quantified the percentage of tumor cells whose nuclei stained with the Mitf antibody visually. Survival curves were generated using the Kaplan-Meier method. The correlation between Mitf expression and nodal status was evaluated using the Mann-Whitney U-test. Here we demonstrate that Mitf expression is directly correlated with both disease-free survival (DFS) and overall survival (OS) over a median follow-up of 28.5 months. The mean DFS and OS in the eight patients whose melanomas did not stain positive for Mitf were 15.75±3.36 months (median, 12 months) and 38.17±5.18 months (median, 29 months), respectively. These results are significantly lower than those for patients who showed evidence of Mitf expression, in whom the mean DFS and OS were 66.1±4.03 months (median, not reached, P=0.0001) and 66.75±38.17 months (median, not reached, P=0.0001), respectively. The mean DFS and OS with greater than 25% (67 patients) of the melanoma cells staining positive for Mitf expression were 78.37±2.78 and 82.38±1.6 months, respectively, compared with 26.37±3.2 months (P=0.0001) and 44.53±4.5 months (P=0.0001), respectively, with up to 25% (27 patients) of cells stained positive for Mitf expression. In addition, there was a significant relationship between Mitf expression and nodal status, as evaluated by sentinel node biopsy. For example, none of the melanomas with greater than 50% Mitf expression had a positive sentinel node biopsy. Our study shows that expression of the molecular marker Mitf in primary cutaneous melanomas is a useful tool in assessing lymph node status. Mitf immunostaining in the primary tumor serves as a reliable predictor of occult lymph node metastases, as well as a favorable prognosticator of DFS and OS in melanoma patients.

Abstract
INTRODUCTION While SLN biopsy is recommended for melanoma ≥1 mm in depth, its use among the elderly population is more controversial. We reviewed our experience at the University of Michigan with melanoma patients ≥75 years of age. METHODS A total of 952 melanoma patients ≥75 years of age from 1996 to 2011 were identified from our institutional review board-approved database. In addition to clinicopathologic features and outcome data, comorbidity data were collected to calculate the Charlson comorbidity index (CCI). Univariate and multivariate Cox regression analysis was performed to characterize predictors of outcome. Kaplan-Meier analysis was used to generate survival curves. RESULTS Among 553 clinically node-negative patients with melanoma ≥1 mm in Breslow thickness, 213 had wide excision alone, whereas 340 had excision and SLN biopsy, with 83 (24 %) having a positive SLN. SLN biopsy was less likely with older age (p < 0.0001) and H&N location (p = 0.007), but not CCI. SLN involvement was associated with female gender [odds ratio (OR) 2.15, p = 0.009], Breslow thickness [OR 1.23/mm increase, p = 0.004], and satellitosis (OR 4.43, p = 0.004). Distant disease-specific survival was negatively associated with male gender (OR 1.5, p = 0.007), increasing age (OR 1.05/year, p < 0.001), increasing Breslow thickness (OR 1.07/year, p = 0.013), ulceration (OR 1.51, p = 0.004), a positive SLN (OR 2.61, p < 0.001), and not having a SLN biopsy (OR 1.72, p < 0.001). CCI did not predict worse disease-free or melanoma-specific survival. CONCLUSIONS WLE and SLN biopsy was not only strongly prognostic, but compared with WLE alone was associated with improved outcome, even after factoring for age and comorbidities. If otherwise healthy, SLN biopsy should be strongly considered for this population.

Abstract
BACKGROUND Histological features such as Breslow thickness, ulceration and mitosis are the main criteria to guide sentinel lymph node biopsy (SLNB) in melanoma. Dermoscopy may add complementary information to these criteria. OBJECTIVES To evaluate the correlation between dermoscopy structures and SLNB positivity. METHODS Retrospective analysis of 123 consecutive melanomas with Breslow thickness > 0·75 mm, SLNB performed during follow-up and dermoscopic images. RESULTS Men were more likely to have a positive SLNB. The presence of ulceration and blotch and the absence of a pigmented network in dermoscopy correlated with positive SLNB. Histological ulceration also correlated with positive SLNB. A dermoscopy SCORE predicted SLN status with a sensitivity of 96·3% and a specificity of 30·2%. When sex and Breslow thickness were added (SCOREBRESEX), the sensitivity remained at 96·3% but the specificity increased to 52·1%. This study is limited by the number of patients and was performed in only one institution. CONCLUSIONS Dermoscopy allowed a more precise prediction of SLN status. If a combined SCOREBRESEX was used to select patients for SLNB, 41·5% of procedures might be avoided.

Abstract
The aim of the present study was to evaluate the frequency and type of oncogenic v-raf murine sarcoma viral oncogene homolog B1 (BRAF)/neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS) mutations in cutaneous melanoma with clinically detected nodal metastases (stage IIIB and C) in relation to clinicopathological features and outcome. The clinicopathological data of 250 patients following therapeutic lymphadenectomy (LND) between 1995 and 2010, as well as BRAF/NRAS mutational status in corresponding nodal metastases, were analyzed. The median follow-up time was 53 months. BRAF mutations were detected in 154 (62%) cases (141 p.V600E, nine p.V600K and four others) and mutually exclusive NRAS mutations were detected in 42 (17%) cases. The presence of a BRAF mutation was found to correlate with patients of a younger age. The five-year overall survival (OS) rate was 33 and 43% for LND and primary tumor excision, respectively, and the five-year disease-free survival (DFS) rate for LND was 25%. No correlation was identified between BRAF/NRAS mutational status and RFS or OS (calculated from the date of the LND and primary tumor excision); for BRAF- and NRAS-mutated melanoma, the prognosis was the same for patients with wild-type (WT) melanoma. The important factors which had a negative impact on OS and DFS were as follows: Male gender, >1 metastatic lymph node and extracapsular extension of nodal metastases. The interval between the diagnosis of the initial melanoma to regional nodal metastasis (median, 10 months) was not significantly different between BRAF-mutant and -WT patients. Our largest comprehensive molecular analysis of clinical stage III melanoma revealed that BRAF and NRAS mutational status is not a prognostic marker in stage III melanoma patients with macroscopic nodal involvement, but may have implications for potential adjuvant therapy.

BACKGROUND Sentinel lymph node (SLN) biopsy (SLNB) for pT1 melanomas is not generally recognized as a clinical standard. We studied the value of SLNB for pT1 melanoma patients having at least one additional risk factor. PATIENTS Among 931 patients with SLNB, 210 had pT1 melanomas. All of the latter showed at least one of the following risk factors: ulceration (4 %) Clark level IV (44 %), nodular growth pattern (11 %), mitoses (59 %), regression (38 %) or age ≤ 40 years (27 %). RESULTS In this selected pT1 population, we observed a surprisingly high SLN positivity rate of 18 %. The melanoma-specific overall survival significantly depended on SLN status. Compared with Clark IV, a lower invasion level (Clark II/III) was associated with a higher proportion of positive SLNs (25 vs. 10 %; p < 0.01). There was a trend towards a higher SLN positivity rate in younger patients (p = 0.06). Breslow, ulceration, mitoses, nodular growth pattern, and sex did not reach significance. Regression was significantly more frequently found in very thin melanomas (≤ 0.75 mm) and tended to be significant in this subgroup (p = 0.075). CONCLUSIONS SLNB improves prognostic stratification in patients with thin melanomas having an additional risk factor. Clark level IV most likely does not belong to these risk factors. The impact of regression deserves further consideration. Our data suggest that SLNB should be offered to patients with thin melanomas, if ulceration, nodular growth pattern, mitoses, or regression are present, or if the patient is younger than 40 years of age.

Abstract
PURPOSE We have previously reported that older patients with clinical stage I and II primary cutaneous. Melanoma had lower survival rates compared to younger patients. We postulated that the incidence of nodal metastasis would therefore be higher among older melanoma patients. METHODS The expanded American Joint Committee on Cancer melanoma staging database contains a cohort of 7,756 melanoma patients who presented without clinical evidence of regional lymph node or distant metastasis and who underwent a sentinel node biopsy procedure as a component of their staging assessment. RESULTS Although older patients had primary melanoma features associated with more aggressive biology, we paradoxically observed a significant decrease in the incidence of sentinel node metastasis as patient age increased. Overall, the highest incidence of sentinel node metastasis was 25.8 % in patients under 20 years of age, compared to 15.5 % in patients 80 years and older (p < 0.001). In contrast, 5-year mortality rates for clinical stage II patients ranged from a low of 20 % for those 20-40 years of age up to 38 % for those over 70 years of age. Patient age was an independent predictor of sentinel node metastasis in a multifactorial analysis (p < 0.001). CONCLUSIONS Patients with clinical stage I and II melanoma under 20 years of age had a higher incidence of sentinel lymph node metastasis but, paradoxically, a more favorable survival outcome compared to all other age groups. In contrast, patients >70 years had the most aggressive primary melanoma features and a higher mortality rate compared to all other age groups but a lower incidence of sentinel lymph node metastasis.

Abstract
Background. Sentinel lymph node biopsy (SLNB) is a standard procedure for patients with localized cutaneous melanoma. The National Comprehensive Cancer Network (NCCN) Melanoma Panel has reinforced the status of the sentinel lymph node (SLN) as an important prognostic factor for melanoma survival. We sought to identify predictive factors associated with a positive SLNB and overall survival in our population. Methods. We performed a retrospective chart review of 221 patients who have done a successful SLNB for melanoma between 2004 and 2010 at our department. Univariate and multivariate analyses were done. Results. The SLNB was positive in 48 patients (21.7%). Univariate analysis showed that male gender, increasing Breslow thickness, tumor type, and absence of tumor-infiltrating lymphocytes were significantly associated with a positive SLNB. Multivariate analysis confirmed that Breslow thickness and the absence of tumor-infiltrating lymphocytes are independently predictive of SLN metastasis. The 5-year survival rates were 53.1% for SLN positive patients and 88.2% for SLN negative patients. Breslow thickness and the SLN status independently predict overall survival. Conclusions. The risk factors for a positive SLNB are consistent with those found in the previous literature. In addition, the SLN status is a major determinant of survival, which highlights its importance in melanoma management.

Abstract
BACKGROUND Prognostic factors and risk factors for positive sentinel lymph node (SLN) biopsy results are important to identify in superficial spreading melanoma (SSM). METHODS A single-center database and a prospective clinical trial database were reviewed for all patients with diagnoses of SSM. Logistic regression, Kaplan-Meier survival analysis, and univariate and multivariate Cox models were used. RESULTS A total of 1,643 patients with SSM were identified. Independent risk factors for positive SLN biopsy results were Breslow thickness (BT) ≥2.0 mm, age <60 years, and presence of ulceration. BT ≥2.0 mm, ulceration, lymphovascular invasion, and positive SLN and positive non-SLN biopsy results were independent risk factors for worse disease-free survival. Independent overall survival risk factors included BT ≥2.0 mm, age ≥60 years, ulceration, nonextremity tumor location, lymphovascular invasion, and positive SLN biopsy results. CONCLUSIONS BT, ulceration, lymphovascular invasion, and SLN and non-SLN status are important risk factors for SSM.

Abstract
OBJECTIVE To analyze the predictors and patterns of recurrence of melanoma in patients with a negative sentinel lymph node biopsy result. DESIGN Retrospective chart review of a prospectively created database of patients with cutaneous melanoma. SETTING Tertiary university hospital. PATIENTS A total of 515 patients with melanoma underwent a sentinel lymph node biopsy without evidence of metastatic disease between 1996 and 2008. MAIN OUTCOME MEASURES Time to recurrence and overall survival. RESULTS Of 515 patients, 83 (16%) had a recurrence of melanoma at a median of 23 months during a median follow-up of 61 months (range, 1-154 months). Of these 83 patients, 21 had melanoma that metastasized in the studied nodal basin for an in-basin false-negative rate of 4.0%. Patients with recurrence had deeper primary lesions (mean thickness, 2.7 vs 1.8 mm; P < .01) that were more likely to be ulcerated (32.5% vs 13.5%; P < .001) than those without recurrence. The primary melanoma of patients with recurrence was more likely to be located in the head and neck region compared with all other locations combined (31.8% vs 11.7%; P < .001). Median survival following a recurrence was 21 months (range, 1-106 months). Favorable characteristics associated with lower risk of recurrence included younger age at diagnosis (mean, 49 vs 57 years) and female sex (9% vs 21% for males; P < .001). CONCLUSION Overall, recurrence of melanoma (16%) after a negative sentinel lymph node biopsy result was similar to that in previously reported studies with an in-basin false-negative rate of 4.0%. Lesions of the head and neck, the presence of ulceration, increasing Breslow thickness, older age, and male sex are associated with increased risk of recurrence, despite a negative sentinel lymph node biopsy result.

Abstract
BACKGROUND We postulated that the worse prognosis of melanoma with advancing age reflected more aggressive tumor biology and that in younger patients the prognosis would be more favorable. MATERIALS AND METHODS The expanded AJCC melanoma staging database contained 11,088 patients with complete data for analysis, including mitotic rate. RESULTS With increasing age by decade, primary melanomas were thicker, exhibited higher mitotic rates, and were more likely to be ulcerated. In a multivariate analysis of patients with localized melanoma, thickness and ulceration were highly significant predictors of outcome at all decades of life (except for patients younger than 20 years). Mitotic rate was significantly predictive in all age groups except patients <20 and >80 years. For patients with stage III melanoma, there were four independent variables associated with patient survival: number of nodal metastases, patient age, ulceration, and mitotic rate. Patients younger than 20 years of age had primary tumors with slightly more aggressive features, a higher incidence of sentinel lymph node metastasis, but, paradoxically, more favorable survival than all other age groups. In contrast, patients >70 years old had primary melanomas with the most aggressive prognostic features, were more likely to be head and neck primaries, and were associated with a higher mortality rate than the other age groups. Surprisingly, however, these patients had a lower rate of sentinel lymph node metastasis per T stage. Among patients between the two age extremes, clinicopathologic features and survival tended to be more homogeneous. CONCLUSIONS Melanomas in patients at the extremes of age have a distinct natural history.

Abstract
BACKGROUND Previous studies showed conflicting and inconsistent results regarding the effect of anatomic location of the melanoma on sentinel lymph node (SLN) positivity and/or survival. This study was conducted to evaluate and compare the effect of the anatomic locations of primary melanoma on long-term clinical outcomes. METHODS All consecutive cutaneous melanoma patients (n=2,079) who underwent selective SLN dissection (SLND) from 1993 to 2009 in a single academic tertiary-care medical center were included. SLN positive rate, disease-free survival (DFS), and overall survival (OS) were determined. Kaplan-Meier survival, univariate, and multivariate analyses were performed to determine predictive factors for SLN status, DFS, and OS. RESULTS Head and neck melanoma (HNM) had the lowest SLN-positive rate at 10.8% (16.8% for extremity and 19.3% for trunk; P=0.002) but had the worst 5-year DFS (P<0.0001) and 5-year OS (P<0.0001) compared with other sites. Tumor thickness (P<0.001), ulceration (P<0.001), HNM location (P=0.001), mitotic rate (P<0.001), and decreasing age (P<0.001) were independent predictive factors for SLN-positivity. HNM with T3 or T4 thickness had significantly lower SLN positive rate compared with other locations (P≤0.05). Also, on multivariate analysis, HNM location versus other anatomic sites was independently predictive of decreased DFS and OS (P<0.001). By Kaplan-Meier analysis, HNM was associated significantly with the worst DFS and OS. CONCLUSIONS Primary melanoma anatomic location is an independent predictor of SLN status and survival. Although HNM has a decreased SLN-positivity rate, it shows a significantly increased risk of recurrence and death as compared with other sites.

Abstract
BACKGROUND Risk-factors for leg swelling following primary melanoma excision and inguinal sentinel lymphadenectomy (SLNE) have not been sufficiently investigated. PATIENTS AND METHODS We prospectively studied three parameters in 105 subjects: 1) subjectively perceived swelling, 2) clinically diagnosed swelling and 3) photo-optical measurement of volume differences between both legs. RESULTS Perceived swelling, clinically diagnosed swelling, and manifest edema occurred in 31%, 15%, and 7% of patients respectively. Following inguinal SLNE, there was a mean volume increase of 1.5% in the operated leg. Both the lower leg and the thigh increased in volume. Obesity, primary melanoma location on the lower leg, and inguinal seromas were identified as significant risk factors for postoperative swelling. Wider excision margins around a primary melanoma on the thigh were also associated with a significant increase in volume. Age, sex, the number of sentinel lymph nodes, the drainage fluid volume, and the time since SLNE were non-significant. CONCLUSIONS Both inguinal SLNE and primary melanoma excision may contribute to minimal fluid accumulation in the leg. More than two-thirds of patients did not have any swelling. Obesity, location of the primary melanoma at a distal site on the leg, a wide safety margin, and seromas are associated with postoperative leg swelling.

Increasing Age Is Associated with Worse Prognostic Factors and Increased Distant Recurrences despite Fewer Sentinel Lymph Node Positives in Melanoma. Int J Surg Oncol 2012; 2012:456987.

Abstract
Background. Advanced age is associated with a poorer prognosis in patients with melanoma. Despite this established finding, a decreased incidence of positive sentinel lymph nodes (SLNs) with advancing age has paradoxically been described. Methods. Using a single-institution database of melanoma patients between 1994 and 2009, the relationship between standard clinicopathologic variables and recurrence based on age was evaluated. Results. 1244 patients who underwent successful SLN biopsies were analyzed (mean followup 80.3 months). Increasing age was independently associated with worse survival on multivariable analysis (P = 0.02). SLN status was more likely to be negative if the patient was older (P = 0.01). Conclusions. Our data supports the paradox that increasing age is associated with a lower frequency of positive-SLN biopsies despite age itself being a poor prognostic factor. We propose that age-dependent variations in the primary tumor and the patient may predispose to a hematogenous route of spread for the older population, leading to worse survival.

Abstract
BACKGROUND Numerous predictive factors for cutaneous melanoma metastases to sentinel lymph nodes have been identified; however, few have been found to be reproducibly significant. This study investigated the significance of factors for predicting regional nodal disease in cutaneous melanoma using a large multicenter database. METHODS Seventeen institutions submitted retrospective and prospective data on 3463 patients undergoing sentinel lymph node (SLN) biopsy for primary melanoma. Multiple demographic and tumor factors were analyzed for correlation with a positive SLN. Univariate and multivariate statistical analyses were performed. RESULTS Of 3445 analyzable patients, 561 (16.3%) had a positive SLN biopsy. In multivariate analysis of 1526 patients with complete records for 10 variables, increasing Breslow thickness, lymphovascular invasion, ulceration, younger age, the absence of regression, and tumor location on the trunk were statistically significant predictors of a positive SLN. CONCLUSIONS These results confirm the predictive significance of the well-established variables of Breslow thickness, ulceration, age, and location, as well as consistently reported but less well-established variables such as lymphovascular invasion. In addition, the presence of regression was associated with a lower likelihood of a positive SLN. Consideration of multiple tumor parameters should influence the decision for SLN biopsy and the estimation of nodal metastatic disease risk.
