Abstract
INTRODUCTION Effective systemic therapy (EST) in patients with metachronous metastatic melanoma (MMM) improves survival and alters surgical decision-making. Surgical metastasectomy is another treatment option, however, it is unclear if metastasectomy confers survival benefit. This study seeks to identify any survival benefit associated with surgical management of MMM. METHODS Patients with MMM from 2009 to 2021 were grouped by receipt of metastasectomy and treatment era (pre-versus post-EST). Overall survival (OS) was calculated from date of metastasis and evaluated with Kaplan-Meier analysis. RESULTS Our dataset identified 226 patients with MMM; 32% were diagnosed pre-EST. On Kaplan-Meier analysis, OS was improved for patients undergoing treatment post-versus pre-EST (p < 0.001). In the post-EST era, metastasectomy was associated with an increase in OS compared to no resection (p = 0.022). CONCLUSIONS In the post-EST group, EST paired with metastasectomy was associated with improved OS compared to the pre-EST group, suggesting persistent evidence of a survival benefit from metastasectomy.

Abstract
BACKGROUND Subungual melanoma (SUM) is a rare tumor with historically poor outcomes. Thus, the benefit of proximal versus distal amputation in SUM remains unclear. METHODS We performed a retrospective review of our prospectively-maintained institutional melanoma database, including SUM and non-subungual acral melanoma (AM) patients who underwent sentinel lymph node biopsy (SLNB) between 1999 and 2022. All SUMs had distal joint or proximal amputations. Primary endpoints were overall survival (OS) and recurrence free survival (RFS). Kaplan-Meier estimates, and Cox univariate and multivariate analyses were performed. Tests were repeated on propensity score matched (PSM) populations in a 2:1 ratio. RESULTS 123 patients underwent resection with SLNB for SUM (n = 27) and AM (n = 96). Median follow-up was 9.2 years. Unadjusted median OS was 149.1 months for AM and 198.1 months for SUM. In the PSM comparison, median OS and RFS remained comparable between SUM and AM (149.5 months versus 198.1 months; p = 0.612). Sentinel node positivity was associated with significantly worse overall survival outcome (Hazard Ratio 5.49; CI (1.59-18.97), p = 0.007). In the PSM population, male sex was also associated with a significant hazard of death (HR 3.00, CI (1.03-8.71), p = 0.043). Proximal amputations were associated with significantly worse OS (p < 0.002) and RFS (p < 0.01) compared to distal amputations in SUM. CONCLUSION SUM was well-treated with distal amputations, and had better OS and RFS compared to SUM treated with proximal amputations. Sentinel lymph node status is an important prognostic factor for SUMs and AMs. SUMs can be treated similarly to AMs with comparably good long-term outcomes.

Abstract
BACKGROUND Although sentinel lymph node biopsy (SLNB) status is a strong prognostic indicator for cutaneous melanoma, unnecessary SLNBs have substantial cost and morbidity burden. OBJECTIVE This study was designed to develop, validate, and present a personalized, clinical, decision-making tool using nationally representative data with clinically actionable probability thresholds (Expected Lymphatic Metastasis Outcome [ELMO]). METHODS Data from the Surveillance, Epidemiology, and End Results (SEER) Registry from 2000 to 2017 and the National Cancer Database (NCDB) from 2004 to 2015 were used to develop and internally validate a logistic ridge regression predictive model for SLNB positivity. External validation was done with 1568 patients at a large tertiary referral center. RESULTS The development cohort included 134,809 patients, and the internal validation cohort included 38,518 patients. ELMO (AUC 0.85) resulted in a 29.54% SLNB reduction rate and greater sensitivity in predicting SLNB status for T1b, T2a, and T2b tumors than previous models. In external validation, ELMO had an accuracy of 0.7586 and AUC of 0.7218. Limitations of this study are potential miscoding, unaccounted confounders, and effect modification. CONCLUSIONS ELMO ( https://melanoma-sentinel.herokuapp.com/ ) has been developed and validated (internally and externally) by using the largest publicly available dataset of melanoma patients and was found to have high accuracy compared with other published models and gene expression tests. Individualized risk estimates for SLNB positivity are critical in facilitating thorough decision-making for healthcare providers and patients with melanoma.

Abstract
OBJECTIVE National Comprehensive Cancer Network (NCCN) guidelines for cutaneous melanoma (CM) recommend physicians consider increased surveillance for patients who typically have lower melanoma survival rates (stages IIB-IV as determined by the American Joint Committee on Cancer (AJCC), 8th edition). However, up to 15% of patients identified as having a low recurrence risk (stages I-IIA) experience disease recurrence, and some patients identified as having a high recurrence risk will not experience any recurrence. The 31-gene expression profile test (31-GEP) stratifies patient recurrence risk into low (Class 1) and high (Class 2) and has demonstrated risk-appropriate impact on disease management and clinical decisions. METHODS Five-year plans for lab work, frequency of clinical visits, and imaging pre- and post-31-GEP test results were assessed for a cohort of 509 stage I-III patients following an interim subset analysis of 247 patients. RESULTS After receiving 31-GEP results, 50.6% of patients had a change in management plans in at least one of the following categories-clinical visits, lab work, or surveillance imaging. The changes aligned with the risk predicted by the 31-GEP for 76.1% of patients with a Class 1 result and 78.7% of patients with a Class 2 result. A Class 1 31-GEP result was associated with changes toward low-intensity management recommendations, while a Class 2 result was associated with changes toward high-intensity management recommendations. CONCLUSION The 31-GEP can stratify patient recurrence risk in patients with CM, and clinicians understand and apply the prognostic ability of the 31-GEP test to alter patient management in risk-appropriate directions.

Abstract
PURPOSE Guidelines addressing melanoma in-transit metastasis (ITM) recommend immune checkpoint inhibitors (ICI) as a first-line treatment option, despite the fact that there are no efficacy data available from prospective trials for exclusively ITM disease. The study aims to analyze the outcome of patients with ITM treated with ICI based on data from a large cohort of patients treated at international referral clinics. METHODS A multicenter retrospective cohort study of patients treated between January 2015 and December 2020 from Australia, Europe, and the USA, evaluating treatment with ICI for ITM with or without nodal involvement (AJCC8 N1c, N2c, and N3c) and without distant disease (M0). Treatment was with PD-1 inhibitor (nivolumab or pembrolizumab) and/or CTLA-4 inhibitor (ipilimumab). The response was evaluated according to the RECIST criteria modified for cutaneous lesions. RESULTS A total of 287 patients from 21 institutions in eight countries were included. Immunotherapy was first-line treatment in 64 (22%) patients. PD-1 or CTLA-4 inhibitor monotherapy was given in 233 (81%) and 23 (8%) patients, respectively, while 31 (11%) received both in combination. The overall response rate was 56%, complete response (CR) rate was 36%, and progressive disease (PD) rate was 32%. Median PFS was ten months (95% CI 7.4-12.6 months) with a one-, two-, and five-year PFS rate of 48%, 33%, and 18%, respectively. Median MSS was not reached, and the one-, two-, and five-year MSS rates were 95%, 83%, and 71%, respectively. CONCLUSION Systemic immunotherapy is an effective treatment for melanoma ITM. Future studies should evaluate the role of systemic immunotherapy in the context of multimodality therapy, including locoregional treatments such as surgery, intralesional therapy, and regional therapies.

Abstract
9569 Background: Guidelines addressing melanoma in-transit metastasis (ITM) recommend immune checkpoint inhibitors (ICI) as a first-line treatment option, despite the fact that there are no efficacy data available from prospective trials for exclusively ITM disease. The aim of this study was to analyze the outcome of patients with ITM treated with ICI based on data from a large cohort of patients treated at international high‐volume melanoma centers. Methods: A multicenter retrospective cohort study of patients treated between January 2015 and December 2020 from Australia, Europe, and USA, evaluating treatment with ICI for ITM with or without nodal involvement (AJCC8 N1c, N2c and N3c) and without distant disease (M0). Patients were treated with PD-1 inhibitor (nivolumab or pembrolizumab) and/or CTLA-4 inhibitor (ipilimumab). We assessed response rates, progression-free survival (PFS), melanoma-specific survival (MSS) and overall survival (OS). Results: A total of 287 patients from 21 institutions in 8 countries were included. Immunotherapy was first-line treatment in 64 (22%) patients. Monotherapy with a PD-1 or CTLA-4 inhibitor was given in 233 (81%) and 23 (8%) patients respectively, while 31 (11%) received both in combination. Overall response rate was 56%, complete response (CR) rate 36% and progressive disease (PD) rate 32%. Median PFS was 10 months (95% CI 7.4-12.6 months) with a 1-, 2- and 5-year PFS rate of 48%, 33% and 18% respectively. Median MSS was not reached, and the 1-, 2- and 5-year MSS rates were 95%, 83% and 71% respectively. Conclusions: Systemic immunotherapy is an effective treatment for melanoma ITM. Future studies should evaluate the optimal role for systemic immunotherapy in the context of multimodality therapy including locoregional treatments such as surgery, intralesional therapy, and regional therapies.

Is the presence of tumor-infiltrating lymphocytes predictive of outcomes in patients with melanoma? Cancer 2022; 128:1418-1428. [PMID: 35103302 DOI: 10.1002/cncr.34013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 10/05/2021] [Accepted: 10/06/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND The significance of tumor-infiltrating lymphocytes (TILs) in melanoma is debated. This article presents a multicenter, retrospective study assessing the predictive and prognostic value of TILs. METHODS The Sentinel Lymph Node Working Group database was queried from 1993 to 2018 for cases with known TIL data. TILs were categorized as absent or present, which included nonbrisk (NB), brisk (B), and present but unspecified TIL levels. Clinicopathologic factors were correlated with TILs, sentinel lymph node (SLN) status, and melanoma-specific survival (MSS). RESULTS Overall, 3203 patients were included. The median thickness was 1.5 mm, and 469 cases had SLN metastases. TILs were present in 2458 cases (76.7%), with NB, B, and unspecified TILs seen in 1691 (68.8%), 691 (28.1%), and 76 (3.1%), respectively. Multivariable analysis showed that the presence of TILs significantly predicted a negative SLN biopsy (P < .05). The median follow-up was 25.2 months. MSS was significantly better for cases with TILs than cases without TILs (P < .001). According to multivariable analysis, age, gender, thickness, mitotic rate, ulceration, lymphovascular invasion, and SLN status were significantly prognostic of MSS (all P values < .05). Although TILs were not prognostic of MSS, when multiple imputation was used and the SLN status was excluded, the presence of TILs was significantly prognostic of improved MSS (hazard ratio, 0.78; 95% confidence interval, 0.64-0.95; P = .0154). CONCLUSIONS TILs are a favorable marker because their presence significantly predicts a negative SLN, and the absence of TILs may be a prognostic marker of worse survival in patients with a positive SLN but not a negative SLN. TILs may also serve as a prognostic marker of survival when the SLN status is not considered.

Abstract
Background Acral lentiginous melanoma is associated with worse survival than other subtypes of melanoma. Understanding prognostic factors for survival and recurrence can help better inform follow-up care. Objectives To analyze the clinicopathologic features, melanoma-specific survival, and recurrence-free survival by substage in a large, multi-institutional cohort of primary acral lentiginous melanoma patients. Methods Retrospective review of the United States Melanoma Consortium database, a multi-center prospectively collected database of acral lentiginous melanoma patients treated between January 2000 and December 2017. Results Of the 433 primary acral lentiginous melanoma patients identified (median [range] age: 66 [8–97] years; 53% female, 83% white), 66% presented with stage 0–2 disease and the median time of follow-up for the 392 patients included in the survival analysis was 32.5 months (range: 0–259). The 5-year melanoma-specific survivals by stage were 0 = 100%, I = 93.8%, II = 76.2%, III = 63.4%, IIIA = 80.8%, and IV = 0%. Thicker Breslow depth ((HR) = 1.13; 95% CI = 1.05–1.21; P < .001)) and positive nodal status ((HR) = 1.79; 95% CI = 1.00–3.22; P = .050)) were independent prognostic factors for melanoma-specific survival. Breslow depth ((HR = 1.13; 95% CI = 1.07–1.20; P < .001), and positive nodal status (HR = 2.12; 95% CI = 1.38–3.80; P = .001) were also prognostic factors for recurrence-free survival. Conclusion In this cohort of patients, acral lentiginous melanoma was associated with poor outcomes even in early stage disease, consistent with prior reports. Stage IIB and IIC disease were associated with particularly low melanoma-specific and recurrence-free survival. This suggests that studies investigating adjuvant therapies in stage II patients may be especially valuable in acral lentiginous melanoma patients.

Abstract
National guidelines recommend sentinel lymph node biopsy (SLNB) be offered to patients with > 10% likelihood of sentinel lymph node (SLN) positivity. On the other hand, guidelines do not recommend SLNB for patients with T1a tumors without high-risk features who have < 5% likelihood of a positive SLN. However, the decision to perform SLNB is less certain for patients with higher-risk T1 melanomas in which a positive node is expected 5%-10% of the time. We hypothesized that integrating clinicopathologic features with the 31-gene expression profile (31-GEP) score using advanced artificial intelligence techniques would provide more precise SLN risk prediction.

Abstract
PURPOSE We hypothesized that initial biopsy may understage acral lentiginous melanoma (ALM) and lead to undertreatment or incomplete staging. Understanding this possibility can potentially aid surgical planning and improve primary tumor staging. METHODS A retrospective review of primary ALMs treated from 2000 to 2017 in the US Melanoma Consortium database was performed. We reviewed pathology characteristics of initial biopsy, final excision specimens, surgical margins, and sentinel lymph node biopsy (SLNB). RESULTS We identified 418 primary ALMs (321 plantar, 34 palmar, 63 subungual) with initial biopsy and final pathology results. Median final thickness was 1.8 mm (range 0.0-19.0). There was a discrepancy between initial biopsy and final pathology thickness in 180 (43%) patients with a median difference of 1.6 mm (range 0.1-16.4). Final T category was increased in 132 patients (32%), including 47% of initially in situ, 32% of T1, 39% of T2, and 28% of T3 lesions. T category was more likely to be increased in subungual (46%) and palmar (38%) melanomas than plantar (28%, p = 0.01). Among patients upstaged to T2 or higher, 71% had ≤ 1-cm margins taken. Among the 27 patients upstaged to T1b or higher, 8 (30%) did not have a SLNB performed, resulting in incomplete initial staging. CONCLUSIONS In this large series of ALMs, final T category was frequently increased on final pathology. A high index of suspicion is necessary for lesions initially in situ or T1 and consideration should be given to performing additional punch biopsies, wider margin excisions, and/or SLNB.

Abstract
Lymphocele is a common wound complication of sentinel lymph node biopsy (SLNB). The surgical technique may play a key role in lymphocele formation. This study compared rates of postoperative lymphocele formation by different surgical techniques (Harmonic Scalpel [HS], LigaSure [LS], and traditional electrocautery with clips) after SLNB in the groin or axilla for the staging of clinically node-negative cutaneous melanoma. Patients were selected by convenience sample from a single-institution, single-surgeon, prospectively collected melanoma database over a 27-month period. One hundred fifty consecutive patients underwent SLNB, 70 with clips, 37 with HS, and 43 with LS. The median number of nodes removed was two and did not vary significantly between groups. Twenty-three lymphoceles occurred for an overall rate of 15 per cent; rates were 9.9 and 26.5 per cent for the axilla and groin, respectively. Sixteen (70%) were aspirated for size or symptoms; lymphoceles after groin SLNB were significantly (P = 0.03) more likely to require aspiration. Lymphocele rates for the clip, HS, and LS groups were 20.0, 18.9, and 4.7 per cent, respectively. The differences between the LS and other groups were statistically significant. Use of the LS may lead to lower lymphocele rates after groin and axillary SLNB compared with electrocautery and clips.

Abstract
INTRODUCTION Patient age has been intermittently associated with demographics and outcomes in cutaneous melanoma. We looked at the association of age and patient demographics, tumor features, and melanoma-related outcomes in patients undergoing sentinel lymph node (SLN) biopsy for melanoma. METHODS We reviewed demographics (age, gender), tumor features (mean Breslow thickness, ulceration, SLN positivity rates), and outcomes (all-site relapse, progression to stage IV, death from melanoma, complications) from a university-based prospective database of 1633 patients. Patients were grouped by decade of age and the impact of age was examined by univariable and multivariable analyses. RESULTS Increasing age was directly associated with number of patients referred for SLN biopsy, male gender, head and neck (H&N) tumor location, mean Breslow thickness, tumor ulceration, and with all -site relapse, progression to stage IV, death from melanoma and complication rates. Increasing age was indirectly associated with SLN positivity rates. Comparing ages <30 with ages >60, these trends reached statistical significance for male gender, H&N location, SLN positivity, all-site relapse, progression to stage IV (development of metastases) and death from melanoma. CONCLUSIONS Referrals for SLN biopsy increase with increasing patient age, yet increasing age is associated with lower SLN positivity rates. This occurs despite the fact that older patients have thicker, more ulcerated tumors, and higher melanoma-related relapse and death rates.

Abstract
6630 Background: Sentinel lymph node biopsy (SLNB) is recommended as a staging procedure for patients with cutaneous melanoma (CM), but SLNB is associated with additional surgical risks and costs. The SLN positivity rate is approximately 12-16% overall and varies by age. Older patients have lower SLN positivity rates despite a higher metastatic rate. A 31-gene expression profile (31-GEP) test classifies 5-year metastatic risk (Classes 1A [lowest risk], 1B, 2A, and 2B [highest risk]), including SLN metastasis. As previously demonstrated using a large multicenter database, patients with Class 1A, T1-T2 (≤2.0 mm thickness) CM have an overall SLN positivity likelihood < 5%, below the NCCN guideline threshold for SLNB. The aim of this study was to determine the relative cost impact of patient management via traditional care versus using the 31-GEP test to guide SLNB and surveillance plans for 16,572 patients ≥65 years (Medicare-eligible) with T1-T2 CM who are SLNB-eligible. Methods: Decision tree models were used to compare management strategies (surveillance, SLNB) according to traditional care based on SLNB staging and with 31-GEP test utilization. Models used T category from AJCC TNM staging guidelines and SEER data for incidence estimations. Model outcomes included total Medicare costs of melanoma treatment and patient management. Cost impact of the 31-GEP test was calculated based on the difference in Medicare costs between the traditional care and 31-GEP test paradigms. Results: Under the paradigm in which the 31-GEP guided SLNB and surveillance in patients ≥65 years with T1-T2 CM who are eligible for SLNB, 11,157 fewer SLNBs would be performed per year, a 67% reduction in SLNB procedures in this population. This would result in a net annual cost savings of $68M, a 31% reduction in total costs. Use of the 31-GEP testing to guide surveillance in patients ≥65 with T3-T4 melanoma, in addition to T1-T2 melanoma, were also analyzed and also demonstrated a reduction in costs. Conclusions: Results from this study suggest that using the 31-GEP test to guide SLNB and surveillance offers substantial cost savings compared to traditional care for Medicare-eligible patients.

Abstract
Aim: Can gene expression profiling be used to identify patients with T1–T2 melanoma at low risk for sentinel lymph node (SLN) positivity? Patients & methods: Bioinformatics modeling determined a population in which a 31-gene expression profile test predicted <5% SLN positivity. Multicenter, prospectively-tested (n = 1421) and retrospective (n = 690) cohorts were used for validation and outcomes, respectively. Results: Patients 55–64 years and ≥65 years with a class 1A (low-risk) profile had SLN positivity rates of 4.9% and 1.6%. Class 2B (high-risk) patients had SLN positivity rates of 30.8% and 11.9%. Melanoma-specific survival was 99.3% for patients ≥55 years with class 1A, T1–T2 tumors and 55.0% for class 2B, SLN-positive, T1–T2 tumors. Conclusion: The 31-gene expression profile test identifies patients who could potentially avoid SLN biopsy.

Abstract
Background We report the performance of a gene expression profile test to classify the recurrence risk of cutaneous melanoma tumors of the head and neck as low‐risk Class 1 or high‐risk Class 2. Methods Of note, 157 primary head and neck cutaneous melanoma tumors were identified. Survival analyses were performed using Kaplan‐Meier and Cox methods. Results Gene expression profile class and node status stratified tumors into significantly different 5‐year survival groups by Kaplan‐Meier method (P < .0001 for all end points), and both were independent predictors of recurrence in multivariate analysis. Overall, 74% of distant metastases and 88% of melanoma‐specific deaths had Class 2 risk. Conclusion The gene expression profile test identifies cases at increased risk for metastasis and death independent of a clinically or pathologically negative nodal status, suggesting that incorporation of this molecular tool could improve clinical management of patients with head and neck cutaneous melanoma, especially in those with a negative sentinel lymph node biopsy.
