Sex Differences in Odds of Brain Metastasis and Outcomes by Brain Metastasis Status after Advanced Melanoma Diagnosis. Cancers (Basel) 2024; 16:1771. [PMID: 38730723 PMCID: PMC11083203 DOI: 10.3390/cancers16091771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 04/23/2024] [Accepted: 04/29/2024] [Indexed: 05/13/2024] Open
Abstract
Sex differences in cancer are well-established. However, less is known about sex differences in diagnosis of brain metastasis and outcomes among patients with advanced melanoma. Using a United States nationwide electronic health record-derived de-identified database, we evaluated patients diagnosed with advanced melanoma from 1 January 2011-30 July 2022 who received an oncologist-defined rule-based first line of therapy (n = 7969, 33% female according to EHR, 35% w/documentation of brain metastases). The odds of documented brain metastasis diagnosis were calculated using multivariable logistic regression adjusted for age, practice type, diagnosis period (pre/post-2017), ECOG performance status, anatomic site of melanoma, group stage, documentation of non-brain metastases prior to first-line of treatment, and BRAF positive status. Real-world overall survival (rwOS) and progression-free survival (rwPFS) starting from first-line initiation were assessed by sex, accounting for brain metastasis diagnosis as a time-varying covariate using the Cox proportional hazards model, with the same adjustments as the logistic model, excluding group stage, while also adjusting for race, socioeconomic status, and insurance status. Adjusted analysis revealed males with advanced melanoma were 22% more likely to receive a brain metastasis diagnosis compared to females (adjusted odds ratio [aOR]: 1.22, 95% confidence interval [CI]: 1.09, 1.36). Males with brain metastases had worse rwOS (aHR: 1.15, 95% CI: 1.04, 1.28) but not worse rwPFS (adjusted hazard ratio [aHR]: 1.04, 95% CI: 0.95, 1.14) following first-line treatment initiation. Among patients with advanced melanoma who were not diagnosed with brain metastases, survival was not different by sex (rwOS aHR: 1.06 [95% CI: 0.97, 1.16], rwPFS aHR: 1.02 [95% CI: 0.94, 1.1]). This study showed that males had greater odds of brain metastasis and, among those with brain metastasis, poorer rwOS compared to females, while there were no sex differences in clinical outcomes for those with advanced melanoma without brain metastasis.

Brain metastasis and survival outcomes after first-line therapy in metastatic melanoma: a multicenter DeCOG study on 1704 patients from the prospective skin cancer registry ADOREG. J Immunother Cancer 2023; 11:e005828.

Abstract
BACKGROUND Despite the availability of effective systemic therapies, a significant number of advanced melanoma patients develops brain metastases. This study investigated differences in incidence and time to diagnosis of brain metastasis and survival outcomes dependent on the type of first-line therapy. METHODS Patients with metastatic, non-resectable melanoma (AJCCv8 stage IIIC-V) without brain metastasis at start of first-line therapy (1L-therapy) were identified from the prospective multicenter real-world skin cancer registry ADOREG. Study endpoints were incidence of brain metastasis, brain metastasis-free survival (BMFS), progression-free survival (PFS), and overall survival (OS). RESULTS Of 1704 patients, 916 were BRAF wild-type (BRAFwt) and 788 were BRAF V600 mutant (BRAFmut). Median follow-up time after start of 1L-therapy was 40.4 months. BRAFwt patients received 1L-therapy with immune checkpoint inhibitors (ICI) against CTLA-4+PD-1 (n=281) or PD-1 (n=544). In BRAFmut patients, 1L-therapy was ICI in 415 patients (CTLA-4+PD-1, n=108; PD-1, n=264), and BRAF+MEK targeted therapy (TT) in 373 patients. After 24 months, 1L-therapy with BRAF+MEK resulted in a higher incidence of brain metastasis compared with PD-1±CTLA-4 (BRAF+MEK, 30.3%; CTLA-4+PD-1, 22.2%; PD-1, 14.0%). In multivariate analysis, BRAFmut patients developed brain metastases earlier on 1L-therapy with BRAF+MEK than with PD-1±CTLA-4 (CTLA-4+PD-1: HR 0.560, 95% CI 0.332 to 0.945, p=0.030; PD-1: HR 0.575, 95% CI 0.372 to 0.888, p=0.013). Type of 1L-therapy, tumor stage, and age were independent prognostic factors for BMFS in BRAFmut patients. In BRAFwt patients, tumor stage was independently associated with longer BMFS; ECOG Performance status (ECOG-PS), lactate dehydrogenase (LDH), and tumor stage with OS. CTLA-4+PD-1 did not result in better BMFS, PFS, or OS than PD-1 in BRAFwt patients. For BRAFmut patients, multivariate Cox regression revealed ECOG-PS, type of 1L-therapy, tumor stage, and LDH as independent prognostic factors for PFS and OS. 1L-therapy with CTLA-4+PD-1 led to longer OS than PD-1 (HR 1.97, 95% CI 1.122 to 3.455, p=0.018) or BRAF+MEK (HR 2.41, 95% CI 1.432 to 4.054, p=0.001), without PD-1 being superior to BRAF+MEK. CONCLUSIONS In BRAFmut patients 1L-therapy with PD-1±CTLA-4 ICI resulted in a delayed and less frequent development of brain metastasis compared with BRAF+MEK TT. 1L-therapy with CTLA-4+PD-1 showed superior OS compared with PD-1 and BRAF+MEK. In BRAFwt patients, no differences in brain metastasis and survival outcomes were detected for CTLA-4+PD-1 compared with PD-1.

Necrosis in Patients with Intracranial Metastasis from Melanoma. Clin Med Insights Oncol 2023; 17:11795549231161878. [PMID: 36968334 PMCID: PMC10034291 DOI: 10.1177/11795549231161878] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 02/19/2023] [Indexed: 03/24/2023] Open
Abstract
Background: Radiation necrosis (RN) is a clinically relevant complication of stereotactic
radiosurgery (SRS) for intracranial metastasis (ICM) treatments. Radiation
necrosis development is variable following SRS. It remains unclear if risk
factors for and clinical outcomes following RN may be different for melanoma
patients. We reviewed patients with ICM from metastatic melanoma to
understand the potential impact of RN in this patient population. Methods: Patients who received SRS for ICM from melanoma at Mayo Clinic Arizona
between 2013 and 2018 were retrospectively reviewed. Data collected included
demographics, tumor characteristics, radiation parameters, prior surgical
and systemic treatments, and patient outcomes. Radiation necrosis was
diagnosed by clinical evaluation including brain magnetic resonance imaging
(MRI) and, in some cases, tissue evaluation. Results: Radiation necrosis was diagnosed in 7 (27%) of 26 patients at 1.6 to 38
months following initial SRS. Almost 92% of all patients received systemic
therapy and 35% had surgical resection prior to SRS. Patients with RN
trended toward having larger ICM and a prior history of surgical resection,
although statistical significance was not reached. Among patients with
resection, those who developed RN had a longer period between surgery and
SRS start (mean 44 vs 33 days). Clinical improvement following treatment for
RN was noted in 2 (29%) patients. Conclusions: Radiation necrosis is relatively common following SRS for treatment of ICM
from metastatic melanoma and clinical outcomes are poor. Further studies
aimed at mitigating RN development and identifying novel approaches for
treatment are warranted.

Abstract
Melanomas frequently metastasize to the brain. Despite recent progress in the treatment of melanoma brain metastasis, therapy resistance and relapse of disease remain unsolved challenges. CCT196969 is a SRC family kinase (SFK) and Raf proto-oncogene, serine/threonine kinase (RAF) inhibitor with documented effects in primary melanoma cell lines in vitro and in vivo. Using in vitro cell line assays, we studied the effects of CCT196969 in multiple melanoma brain metastasis cell lines. The drug effectively inhibited proliferation, migration, and survival in all examined cell lines, with viability IC50 doses in the range of 0.18–2.6 μM. Western blot analysis showed decreased expression of p-ERK, p-MEK, p-STAT3 and STAT3 upon CCT196969 treatment. Furthermore, CCT196969 inhibited viability in two B-Raf Proto-Oncogene (BRAF) inhibitor resistant metastatic melanoma cell lines. Further in vivo studies should be performed to determine the treatment potential of CCT196969 in patients with treatment-naïve and resistant melanoma brain metastasis.

Abstract
BACKGROUND Combined PD-1/PD-L1 and CTLA-4 immune checkpoint inhibition for the has been shown to produce superior results in the treatment of malignant melanoma when compared to monotherapy. However, patients with intracranial disease were excluded from these studies given their poor prognosis. OBJECTIVE The objective of this study was to critically assess current evidence supporting the co-administration of PD-1/PD-L1 and CTLA-4 inhibitors in the treatment of melanoma brain metastases. METHODS The objective was addressed through the development of a critically appraised topic that included a clinical scenario, structured question, literature search strategy, critical appraisal, assessment of results, evidence summary, commentary, and bottom-line conclusions. Participants included consultant and resident neurologists, a medical librarian, clinical epidemiologists, and a content expert in the field of neuro-oncology. RESULTS A recent, open-label, non-comparative randomized phase II trial was selected for critical appraisal. This trial evaluated the efficacy and safety of nivolumab alone or in combination with ipilimumab in 79 adult patients with untreated, asymptomatic melanoma brain metastases. The rates of the primary outcome (intracranial response at ≥12 wk) in the primary endpoint cohort were 46% for cohort A (combination therapy) and 20% for cohort B (nivolumab monotherapy). No treatment related deaths were observed in the study. Grade 4 adverse events occurred in 9% of patients in cohort A and none in cohort B. CONCLUSIONS Co-administration of ipilimumab and nivolumab as first-line therapy is effective in the treatment of asymptomatic melanoma brain metastases, with an acceptable safety profile.

Abstract
BACKGROUND Melanoma is a type of malignant tumor with high aggressiveness and poor prognosis. At present, metastasis of melanoma is still an important cause of death in melanoma patients. However, the potential functions and molecular mechanisms of most circular RNAs (circRNAs) in melanoma metastasis remain unknown. METHODS circRNAs dysregulated in melanoma cell subgroups with different metastatic abilities according to a screening model based on repeated Transwell assays were identified with a circRNA array. The expression and prognostic significance of circZNF609 in skin cutaneous melanoma and acral melanoma cells and tissues were determined by qRT-PCR, nucleoplasmic separation assays and fluorescence in situ hybridization. In vitro wound healing, Transwell and 3D invasion assays were used to analyse melanoma cell metastasis ability. Tail vein injection and intrasplenic injection were used to study in vivo lung metastasis and liver metastasis, respectively. The mechanism of circZNF609 was further evaluated via RNA immunoprecipitation, RNA pull-down, silver staining, and immunofluorescence colocalization assays. RESULTS circZNF609 was stably expressed at low levels in melanoma tissues and cells and was negatively correlated with Breslow depth, clinical stage and prognosis of melanoma patients. circZNF609 inhibited metastasis of acral and cutaneous melanoma in vivo and in vitro. Mechanistically, circZNF609 promoted the binding of FMRP protein and RAC1 mRNA, thereby enhancing the inhibitory effect of FMRP protein on the stability of RAC1 mRNA and ultimately inhibiting melanoma metastasis. CONCLUSIONS Our findings revealed that circZNF609 plays a vital role in the metastasis of acral and cutaneous melanoma through the circRNF609-FMRP-RAC1 axis and indicated that circZNF609 regulates the stability of RAC1 mRNA by combining with FMRP, which might provide insight into melanoma pathogenesis and a new potential target for treatment of melanoma.

Abstract
Brain metastases from solid tumors are increasing in incidence, especially as outcomes of systemic therapies continue to extend patients’ overall survival. The long-held notion that the brain is an immune sanctuary has now been largely refuted with increasing evidence that immunotherapy can induce durable responses in brain metastases. Single agent immune checkpoint inhibition with anti-CTLA4 and anti-PD1 antibodies induces durable responses in 15%–20% in melanoma brain metastases as long as patients are asymptomatic and do not require corticosteroids. The combination of anti-CTLA4 with anti-PD-1 antibodies induces an intracranial response in over 50% of asymptomatic melanoma patients, and much lower rate of otherwise durable responses (20%) in symptomatic patients or those on steroids. Data in other cancers, such as renal cell carcinoma, are accumulating indicating a role for immunotherapy. Emerging immunotherapy approaches will have to focus on increasing response rates, decreasing toxicity, and decreasing steroid dependency. The path to those advances will have to include a better understanding of the mechanisms of response and resistance to immunotherapy in brain metastases, the use of novel agents such as anti-LAG3 checkpoint inhibitors, targeted therapy (oncogene directed or TKIs), and possibly surgery and SRS to improve the outcomes of patients with brain metastases.

Abstract
INTRODUCTION The study aimed to describe the brain metastases (BM) incidence, at diagnosis and follow-up, in patients initially presenting with stage III or IV melanoma and characterize their metastatic brain lesions. We also sought to describe the association of common genetic mutations and immunotherapy with BM development in advanced melanoma. METHODS Using our institution's tumor registry, we identified patients with initial diagnoses of stage III and stage IV melanoma. In this cohort, we obtained BM incidence at diagnosis and follow-up, characterized the metastatic brain lesions and primary tumor's genetic profile. RESULTS During the follow-up period, 22.9% of patients with an initial diagnosis of stage III developed BM. In this cohort, the median time for BM occurrence was 20 months; [95% CI (14-29)]. Likewise, 37.7% of patients with Stage IV melanoma presented with BM at the time of diagnosis, and 22.7% of remaining patients developed BM at follow-up over a median duration of 6 months [95% CI (4-11)]. Therefore, suggesting an overall incidence of 51.9% in stage IV melanoma. Next, we observed that the incidence of BM development during the follow-up period significantly decreased from 2012 to 2017 (p < 0.001). Lastly, we found a significantly higher frequency of mutational BRAF in the primary tumor of patients with BM (68.7% vs. 31.2%; p = 0.02). CONCLUSIONS While the overall incidence of BM remains high, the decreasing incidence of BM over the follow-up period is promising. Similar BM incidence in patients with an initial diagnosis of stage III or stage IV warrants appropriate imaging surveillance regimen for stage III patients.

Wang X, Haaland B, Hu-Lieskovan S, Colman H, Holmen SL. First line immunotherapy extends brain metastasis free survival, improves overall survival, and reduces the incidence of brain metastasis in patients with advanced melanoma. Cancer Rep (Hoboken) 2021; 4:e1419. [PMID: 34137219 PMCID: PMC8714542 DOI: 10.1002/cnr2.1419] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 04/15/2021] [Accepted: 04/19/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Recent advances in targeted therapy and immunotherapy have improved the prognosis of melanoma patients but brain metastasis remains a major challenge. Currently, it is unclear how existing therapies can be best used to prevent or treat brain metastasis in melanoma patients. AIMS We aimed to assess brain metastasis free survival (BMFS), overall survival (OS), incidence of brain metastases, and sequencing strategies of immunotherapy and targeted therapy in patients with BRAF-mutated advanced melanoma. METHODS AND RESULTS We retrospectively analyzed 683 patients with BRAF-mutated advanced melanoma treated with first line (1L) immunotherapy (N = 266) or targeted therapy (N = 417). The primary outcome was BMFS. Secondary outcomes included OS of all patients and incidence of brain metastases in patients without documented brain metastases prior to 1L therapy. The median BMFS was 13.7 months [95% confidence interval (CI): 12.4-16.0] among all patients. The median BMFS for patients receiving 1L immunotherapy was 41.9 months [95% CI: 22.8-not reached (NR)] and targeted therapy was 11.0 months (95% CI: 8.8-12.5). Median OS results were qualitatively similar to BMFS results. The cumulative incidence of brain metastases for patients receiving 1L targeted therapy was higher than for patients receiving 1L immunotherapy (P < .001). Patients receiving 1L anti-CTLA4 plus anti-PD1 combination immunotherapy only or followed by second line (2L) targeted therapy had better BMFS (HR 0.40, 95% CI: 0.24-0.67, P = .001), improved OS (HR 0.49, 95% CI: 0.30-0.81, P = .005), and reduced incidence of brain metastases (HR 0.47, 95% CI: 0.24-0.67, P = .047) than patients receiving 1L combination BRAF and MEK targeted therapy followed by 2L immunotherapy. CONCLUSION Patients with advanced BRAF mutant melanoma treated with 1L immunotherapy have significantly longer BMFS and OS, and reduced incidence of brain metastases, compared with those treated with 1L targeted therapy. Further studies evaluating the ability of immunotherapy and targeted therapy to improve OS and prevent brain metastases are warranted.

Abstract
Objective Immune checkpoint inhibitor (ICI) therapy has shown activity against melanoma brain metastases. Recently, promising results have also been reported for ICI combination therapy and ICI combined with radiotherapy. We aimed to evaluate radiologic response and adverse event rates of these therapeutic options by a systematic review and meta-analysis. Materials and Methods A systematic literature search of Ovid-MEDLINE and EMBASE was performed up to October 12, 2019 and included studies evaluating the intracranial objective response rates (ORRs) and/or disease control rates (DCRs) of ICI with or without radiotherapy for treating melanoma brain metastases. We also evaluated safety-associated outcomes. Results Eleven studies with 14 cohorts (3 with ICI combination therapy; 5 with ICI combined with radiotherapy; 6 with ICI monotherapy) were included. ICI combination therapy {pooled ORR, 53% (95% confidence interval [CI], 44–61%); DCR, 57% (95% CI, 49–66%)} and ICI combined with radiotherapy (pooled ORR, 42% [95% CI, 31–54%]; DCR, 85% [95% CI, 63–95%]) showed higher local efficacy compared to ICI monotherapy (pooled ORR, 15% [95% CI, 11–20%]; DCR, 26% [95% CI, 21–32%]). The grade 3 or 4 adverse event rate was significantly higher with ICI combination therapy (60%; 95% CI, 52–67%) compared to ICI monotherapy (11%; 95% CI, 8–17%) and ICI combined with radiotherapy (4%; 95% CI, 1–19%). Grade 3 or 4 central nervous system (CNS)-related adverse event rates were not different (9% in ICI combination therapy; 8% in ICI combined with radiotherapy; 5% in ICI monotherapy). Conclusion ICI combination therapy or ICI combined with radiotherapy showed better local efficacy than ICI monotherapy for treating melanoma brain metastasis. The grade 3 or 4 adverse event rate was highest with ICI combination therapy, and the CNS-related grade 3 or 4 event rate was similar. Prospective trials will be necessary to compare the efficacy of ICI combination therapy and ICI combined with radiotherapy.

Immune checkpoint inhibitor therapy may increase the incidence of treatment-related necrosis after stereotactic radiosurgery for brain metastases: a systematic review and meta-analysis. Eur Radiol 2020; 31:4114-4129. [PMID: 33241519 DOI: 10.1007/s00330-020-07514-0] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 09/28/2020] [Accepted: 11/12/2020] [Indexed: 12/17/2022]
Abstract
OBJECTIVES To compare the incidence of treatment-related necrosis between combination SRS+ICI therapy and SRS therapy alone in patients with brain metastases from melanoma and non-small cell lung cancer (NSCLC). METHODS A systematic literature search of Ovid-MEDLINE and EMBASE was performed up to August 10, 2020. The difference in the pooled incidence of treatment-related necrosis after SRS+ICI or SRS alone was evaluated. The cumulative incidence of treatment-related necrosis at the specific time point after the treatment was calculated and plotted. Subgroup and meta-regression analyses were additionally performed. RESULTS Sixteen studies (14 on melanoma, 2 on NSCLC) were included. In NSCLC brain metastasis, the reported incidences of treatment-related necrosis in SRS+ICI and SRS alone ranged 2.9-3.4% and 0-2.9%, respectively. Meta-analysis was conducted including 14 studies on melanoma brain metastasis. The incidence of treatment-related necrosis was higher in SRS+ICI than SRS alone (16.0% vs. 6.5%; p = 0.065; OR, 2.35). The incidence showed rapid increase until 12 months after the SRS when combined with ICI therapy (14%; 95% CI, 8-22%) and its pace of increase slowed thereafter. Histopathologic diagnosis as the reference standard for treatment-related necrosis and inclusion of only symptomatic cases were the source of heterogeneity in SRS+ICI. CONCLUSIONS Treatment-related necrosis tended to occur 2.4 times more frequently in the setting of combination SRS+ICI therapy compared with SRS alone in melanoma brain metastasis showing high cumulative incidence within the first year. Treatment-related necrosis should be considered when SRS+ICI combination therapy is used for melanoma brain metastasis, especially in the first year. KEY POINTS • Treatment-related necrosis occurred 2.4 times more frequently in the setting of combination SRS+ICI therapy compared with SRS alone in melanoma brain metastasis. • Treatment-related necrosis more frequently occurred in brain metastases from melanoma than NSCLC. • Reference standard for treatment-related necrosis and inclusion of only symptomatic treatment-related necrosis were a significant source of heterogeneity, indicating varying definitions of treatment-related necrosis in the literature need to be unified.

Abstract
Background Although melanoma brain metastases (MBM) tend to respond to systemic therapy concordantly with extracranial metastases, little is known about differences in immune cell and vascular content between the brain and other metastatic sites. Here we studied infiltrating immune cell subsets and microvessel density (MVD) in paired intracerebral and extracerebral melanoma metastases. Methods Paired intracerebral and extracerebral tumor tissue was obtained from 37 patients with metastatic melanoma who underwent craniotomy between 1997 and 2014. A tissue microarray was constructed to quantify subsets of tumor-infiltrating T-cell, B-cell, and macrophage content, PD-L1 expression, and MVD using quantitative immunofluorescence. Results MBM had lower CD3+ (p = 0.01) and CD4+ (p = 0.003) T-cell content, lower MVD (p = 0.006), and a trend for lower CD8+ (p = 0.17) T-cell content compared to matched extracerebral metastases. There were no significant differences in CD20+ B-cell or CD68+ macrophage content, or tumor or stroma PD-L1 expression. Low MVD (p = 0.008) and high CD68+ macrophage density (p = 0.04) in intracerebral metastases were associated with improved 1-year survival from time of first MBM diagnosis. Conclusions Although responses to immune-modulating drugs in the body and the brain tend to be concordant, differences were found in MVD and T-cell content between these sites. Studies of these markers should be incorporated into prospective therapeutic clinical trials to determine their prognostic and predictive value.

Abstract
Background Sixty percent of patients with stage IV melanoma may develop brain metastases, which result in significantly increased morbidity and a poor overall prognosis. Phase 3 studies of melanoma usually exclude patients with untreated brain metastases; therefore, clinical data for intracranial responses to treatments are limited. Methods A multicenter, retrospective case series investigation of consecutive BRAF‐mutant patients with melanoma brain metastases (MBMs) treated with a combination of BRAF inhibitor encorafenib and MEK inhibitor binimetinib was conducted to evaluate the antitumor response. Assessments included the intracranial, extracranial, and global objective response rates (according to the modified Response Evaluation Criteria in Solid Tumors, version 1.1); the clinical benefit rate; the time to response; the duration of response; and safety. Results A total of 24 patients with stage IV BRAF‐mutant MBMs treated with encorafenib plus binimetinib in 3 centers in the United States were included. Patients had received a median of 2.5 prior lines of treatment, and 88% had prior treatment with BRAF/MEK inhibitors. The intracranial objective response rate was 33%, and the clinical benefit rate was 63%. The median time to a response was 6 weeks, and the median duration of response was 22 weeks. Among the 21 patients with MBMs and prior BRAF/MEK inhibitor treatment, the intracranial objective response rate was 24%, and the clinical benefit rate was 57%. Similar outcomes were observed for extracranial and global responses. The safety profile for encorafenib plus binimetinib was similar to that observed in patients with melanoma without brain metastases. Conclusions Combination therapy with encorafenib plus binimetinib elicited intracranial activity in patients with BRAF‐mutant MBMs, including patients previously treated with BRAF/MEK inhibitors. Further prospective studies are warranted and ongoing. All clinical trials to date with encorafenib and binimetinib (US Food and Drug Administration–approved in June 2018 for BRAF‐mutated metastatic melanoma) have excluded untreated melanoma brain metastases. This case series provides the first clinical evidence of intracranial activity of the combination of encorafenib plus binimetinib in patients with BRAF‐mutant melanoma with active brain metastases. Intracranial clinical activity is observed for the first time in patients previously treated with BRAF/MEK inhibitors, a population that has not been previously investigated.

Abstract
Malignant melanoma solitary metastases to bone or skeletal muscle occur in 0.8% of patients. The aim of this study was to evaluate features of skeleton and muscle metastases with multimodality imaging and review the oncological outcome. Thirteen patients with melanoma metastases from January 2006 to February 2016 were included. Histologic confirmation was obtained. Imaging studies included computed tomography (CT), MRI, and/or positron emission tomography/CT. Treatment received and BRAF status were recorded. Differences in BRAF status and overall survival (OS) were analyzed using the χ2-test. Associations between OS and metastases were analyzed using Cox proportional models. Nine (69%) patients showed osseous involvement. Lower extremity bones were affected in three (23%) patients: first toe, right calcaneal spurs, and knee. The spine was involved in three (23%) patients. In two (15%) patients, the pelvic bones were involved. In one (8%) patient, the temporal bone was affected. Nine (70%) patients had a history of malignant melanoma, with a median time to progression of 28 months. The median OS was 18 months: 24 months in patients with a history of melanoma and 3 months in patients with metastases at first diagnosis. The median follow-up duration was 28 months. BRAF mutant versus wild-type tumors showed significant differences in OS (P=0.03). The hazard ratio for death in the metastatic group at diagnosis was 6.83, 95% confidence interval: 1.060–144.072 (P=0.04). Solitary metastases from melanoma to the skeleton and muscle are rare. CT, MRI, and positron emission tomography/CT are useful for the evaluation of musculoskeletal findings. Image findings are not definitive for diagnosing a malignant solitary lesion; thus, a pathologic confirmation with a biopsy is recommended.

Abstract
Pembrolizumab is an immune checkpoint inhibitor approved for the treatment of patients with unresectable or metastatic melanoma. Appearance of bone metastases, either osteolytic or osteoblastic, during treatment qualifies as disease progression. We report the case of a 64-year-old White woman with a metastatic melanoma undergoing second-line treatment with pembrolizumab. At first evaluation, after 3 months of therapy, computed tomography scans showed the onset of osteosclerotic lesions and a significant reduction in all the previously identified metastases; on the contrary, a fluorine-18-fluorodeoxyglucose PET showed the normalization of fluorine-18-fluorodeoxyglucose uptake in all the baseline lesions, including bone metastases. Osteoblastic response, consisting of occurrence of new osteoblastic lesions on computed tomography imaging, as a consequence of an osteoblastic reaction of previously undetectable bone metastases, has been reported in some cancers that receive treatments such as chemotherapy, hormonal or targeted therapy. However, it had never been reported in patients with melanoma treated with immunotherapy. An apparent worsening of bone imaging on standard computed tomography scan in patients under checkpoint inhibitor should not lead to modification of treatment strategy, because misinterpretation as disease progression may lead to the premature cessation of a beneficial treatment and finally have a negative effect on patients' clinical outcome.

Abstract
BACKGROUND After the emergence of new MRI techniques such as susceptibility- and diffusion-weighted imaging (SWI and DWI) and because of specific imaging characteristics of melanoma brain metastases (MBM), it is unclear which MRI sequences are most beneficial for detection of MBM. This study was performed to investigate the sensitivity of six clinical MRI sequences in the early detection of MBM. METHODS Medical records of all melanoma patients referred to our center between November 2005 and December 2016 were reviewed for presence of MBM. Analysis encompassed six MRI sequences at the time of initial diagnosis of first or new MBM, including non-enhanced T1-weighted (T1w), contrast-enhanced T1w (ceT1w), T2-weighted (T2w), T2w-FLAIR, susceptibility-weighted (SWI) and diffusion-weighted (DWI) MRI. Each lesion was rated with respect to its conspicuity (score from 0-not detectable to 3-clearly visible). RESULTS Of 1210 patients, 217 with MBM were included in the analysis and up to 5 lesions per patient were evaluated. A total of 720 metastases were assessed and all six sequences were available for 425 MBM. Sensitivity (conspicuity ≥2) was 99.7% for ceT1w, 77.0% for FLAIR, 64.7% for SWI, 61.0% for T2w, 56.7% for T1w, and 48.4% for DWI. Thirty-one (7.3%) of 425 lesions were only detectable by ceT1w but no other sequence. CONCLUSIONS Contrast-enhanced T1-weighting is more sensitive than all other sequences for detection of MBM. Disruption of the blood-brain-barrier is consistently an earlier sign in MBM than perifocal edema, signal loss on SWI or diffusion restriction.

Abstract
Although ∼40% of patients with metastatic melanoma develop brain metastases, the presence of brain metastases often precludes enrolment in clinical trials for advanced melanoma. However, the development of symptomatic brain metastases markedly increases mortality. The antiprogrammed-death-receptor-1 antibody pembrolizumab achieves extracranial metastases disease response rates of up to 50%. Here, we report the rapid and sustained response of symptomatic multifocal brain metastases in a melanoma ipilimumab-pretreated patient under pembrolizumab, combined with high-dose dexamethasone therapy during the induction phase of therapy. Complete remission has been maintained for over 1 year of follow-up and has correlated with the response rate observed in the extracranial metastases. Radiological disease response was identified during the first follow-up visit in the absence of adjuvant radiotherapy. This report highlights the need for further clinical studies to specifically address the therapeutic potential of antiprogrammed-death-receptor-1 monotherapy in the management of untreated brain metastases in melanoma.

Abstract
Learning objectives To evaluate radiation-induced changes in patients with brain metastasis secondary to malignant melanoma who received treatment with Gamma Knife radiosurgery (GKRS) and programmed cell death 1 (PD-1) receptor antagonists. Introduction Stereotactic radiosurgery and chemotherapeutics are used together for treatment of metastatic melanoma and have been linked to delayed radiation-induced vasculitic leukoencephalopathy (DRIVL). There have been reports of more intense interactions with new immunotherapeutics targeting PD-1 receptors, but their interactions have not been well described and may result in an accelerated response to GKRS. Here we present data on subjects treated with this combination from a single institution. Methods Records from patients who underwent treatment for metastatic melanoma to the brain with GKRS from 2011 to 2016 were reviewed. Demographics, date of brain metastasis diagnosis, cause of death when applicable, immunotherapeutics, and imaging findings were recorded. The timing of radiation therapy and medications were also documented. Results A total of 79 subjects were treated with GKRS, and 66 underwent treatment with both GKRS and immunotherapy. Regarding the 30 patients treated with anti-PD-1 immunotherapy, 21 patients received pembrolizumab, seven patients received nivolumab, and two patients received pembrolizumab and nivolumab. Serial imaging was available for interpretation in 25 patients, with 13 subjects who received GKRS and anti-PD-1 immunotherapy less than six weeks of each other. While four subjects had indeterminate/mixed findings on subsequent magnetic resonance imaging (MRI), nine subjects were noted to have progression. Two of these patients showed progression but subsequent imaging revealed a decrease in progression or improvement on MRI to previously targeted lesions by GKRS. None of the 13 subjects had surgery following their combined therapies. Conclusions This data suggests that there is need for further investigation of the role for concurrent treatment with PD-1 inhibitors and GKRS to enhance the treatment of metastatic melanoma. We present data on 13 patients who appear to have some radiologic benefit to this treatment combination, two of whom had radiographic pseudoprogression.

Abstract
Primary oral malignant melanoma is a rare tumor, which is estimated to comprise 0.2–8.0% of all melanoma cases. This type of cancer is fairly uncommon, its prognosis is dismal, and it frequently exhibits a biologically aggressive behavior. The common location of primary oral malignant melanoma is the hard palate and maxillary alveolus. In ~85% of cases, the melanoma will metastasize to the liver, lung, bone and brain early in the course of the disease. The present study reports the case of a 50-year-old premenopausal woman who presented with primary oral malignant spindle cell melanoma (T3bN2aM0) and underwent complete surgical resection followed by an adjuvant course of radiation therapy. After 1 year, the patient presented with sudden onset slurred speech, and upon examination, was found to have left-sided hemiparesis and a hard left breast mass. Workup confirmed breast and brain metastasis. The patient developed lung metastasis 4 weeks later and was referred for palliative care.

Abstract
INTRODUCTION The clinical landscape of advanced melanoma drastically changed after the introduction of both targeted therapies and immunotherapy. This rapid development in systemic therapies led to a change in the management of patients with brain metastases, with the subsequent need to re-assess the role of local therapies, in particular stereotactic radiosurgery (SRS). Areas covered: In this non-systematic review, we report on the current knowledge on the use of SRS in combination with immunotherapy and BRAF/MEK inhibitors for patients with melanoma brain metastases, as well as ongoing trials in this field. Expert commentary: It is now more common to observe patients with melanoma brain metastases with better performance status and prolonged life expectancy. A combination of targeted therapy and immunotherapy, in different sequences, has been shown to be feasible and well tolerable, on the basis of retrospective reports. Additional data from ongoing prospective trials are however needed to confirm or not these findings and better explore the efficacy of the combination.

Abstract
Brain metastases (BM) occur frequently in many cancers, particularly non-small cell lung cancer (NSCLC), breast cancer, and melanoma. The development of BM is associated with poor prognosis and has an adverse impact on survival and quality of life. Commonly used therapies for BM such as surgery or radiotherapy are associated with only modest benefits. However, recent advances in systemic therapy of many cancers have generated considerable interest in exploration of those therapies for treatment of intracranial metastases.This review discusses the epidemiology of BM from the aforementioned primary tumors and the challenges of using systemic therapies for metastatic disease located within the central nervous system. Cumulative data from several retrospective and small prospective studies suggest that molecularly targeted systemic therapies may be an effective option for the treatment of BM from NSCLC, breast cancer, and melanoma, either as monotherapy or in conjunction with other therapies. Larger prospective studies are warranted to further characterize the efficacy and safety profiles of these targeted agents for the treatment of BM.

Abstract
The development of brain metastases in patients with advanced stage melanoma is common, but the molecular mechanisms responsible for their development are poorly understood. Melanoma brain metastases cause significant morbidity and mortality and confer a poor prognosis; traditional therapies including whole brain radiation, stereotactic radiotherapy, or chemotherapy yield only modest increases in overall survival (OS) for these patients. While recently approved therapies have significantly improved OS in melanoma patients, only a small number of studies have investigated their efficacy in patients with brain metastases. Preliminary data suggest that some responses have been observed in intracranial lesions, which has sparked new clinical trials designed to evaluate the efficacy in melanoma patients with brain metastases. Simultaneously, recent advances in our understanding of the mechanisms of melanoma cell dissemination to the brain have revealed novel and potentially therapeutic targets. In this review, we provide an overview of newly discovered mechanisms of melanoma spread to the brain, discuss preclinical models that are being used to further our understanding of this deadly disease and provide an update of the current clinical trials for melanoma patients with brain metastases.

Abstract
INTRODUCTION A majority of patients with melanoma brain metastases develop multiple lesions, and these patients show particularly poor prognosis. To develop improved treatment strategies, detailed insights into the biology of melanoma brain metastases, and particularly the development of multiple lesions, are needed. The purpose of this preclinical investigation was to study melanoma cell migration within the brain after cell injection into a well-defined intracerebral site. METHODS A-07, D-12, R-18, and U-25 human melanoma cells transfected with green fluorescent protein were injected stereotactically into the right cerebral hemisphere of nude mice. Moribund mice were killed and autopsied, and the brain was evaluated by fluorescence imaging or histological examination. RESULTS Intracerebral inoculation of melanoma cells produced multiple lesions involving all regions of the brain, suggesting that the cells were able to migrate over substantial distances within the brain. Multiple modes of transport were identified, and all transport modes were observed in all four melanoma lines. Thus, the melanoma cells were passively transported via the flow of cerebrospinal fluid in the meninges and ventricles, they migrated actively along leptomeningeal and brain parenchymal blood vessels, and they migrated actively along the surfaces separating different brain compartments. CONCLUSION Migration of melanoma cells after initial arrest, extravasation, and growth at a single location within the brain may contribute significantly to the development of multiple melanoma brain metastases.

Abstract
Melanoma brain metastases are common, difficult to treat, and carry a poor prognosis. Until recently, systemic therapy was ineffective. Local therapy (including surgery, stereotactic radiotherapy, and whole brain radiotherapy) was considered the only option for a chance of disease control in the brain, and was highly dependent on the patient's performance status and age, number and size of brain metastases, and the presence of extracranial metastases. Since 2010, three drugs have demonstrated activity in progressing or "active" brain metastases including the anti-CTLA4 antibody ipilimumab (phase II study of 72 patients), and the BRAF inhibitors dabrafenib (phase II study of 172 patients, both previously treated and untreated brain metastases) and vemurafenib (a pilot study of 24 patients with heavily pretreated brain metastases). The challenge and unanswered question for clinicians is how to sequence all the available therapies, both local and systemic, to optimize the patient's quality of life and survival. This is an area of intense clinical research. The treatment of patients with melanoma brain metastases should be discussed by a multidisciplinary team of melanoma experts including a neurosurgeon, medical oncologist, and radiation oncologist. Important clinical features that help determine appropriate first line therapy include single compared with solitary brain metastasis, resectablity, BRAF mutation status of melanoma, rate of progression/performance status, and the presence of extracranial disease.

Abstract
IMPORTANCE The treatment of multiple brain metastases (MBM) from melanoma is controversial and includes surgical resection, stereotactic radiosurgery (SRS), and whole-brain radiation therapy (WBRT). Several new classes of agents have revolutionized the treatment of metastatic melanoma, allowing some subsets of patients to have long-term survival. Given this, management of MBM from melanoma is continually evolving. OBJECTIVE To review the current evidence regarding the treatment of MBM from melanoma. EVIDENCE REVIEW The PubMed database was searched using combinations of search terms and synonyms for melanoma, brain metastases, radiation, chemotherapy, immunotherapy, and targeted therapy published between January 1, 1995, and January 1, 2015. Articles were selected for inclusion on the basis of targeted keyword searches, manual review of bibliographies, and whether the article was a clinical trial, large observational study, or retrospective study focusing on melanoma brain metastases. Of 2243 articles initially identified, 110 were selected for full review. Of these, the most pertinent 73 articles were included. FINDINGS Patients with newly diagnosed MBM can be treated with various modalities, either alone or in combination. Level 1 evidence supports the use of SRS alone, WBRT, and SRS with WBRT. Although the addition of WBRT to SRS improves the overall brain relapse rate, WBRT has no significant impact on overall survival and has detrimental neurocognitive outcomes. Cytotoxic chemotherapy has largely been ineffective; targeted therapies and immunotherapies have been reported to have high response rates and deserve further attention in larger clinical trials. Further studies are needed to fully evaluate the efficacy of these novel regimens in combination with radiation therapy. CONCLUSIONS AND RELEVANCE At this time, the standard management for patients with MBM from melanoma includes SRS, WBRT, or a combination of both. Emerging data exist to support the notion that SRS in combination with targeted therapies or immune therapy may obviate the need for WBRT; prospective studies are required to fully evaluate the efficacy of these novel regimens in combination with radiation therapy.

Abstract
OBJECTIVE This study sought to assess clinical outcomes in patients receiving gamma knife radiosurgery (GK) for treatment of brain metastases from melanoma and evaluate for potential predictive factors. METHODS We reviewed 188 GK procedures in 129 consecutive patients that were treated for brain metastases from melanoma. The population consisted of 84 males and 45 females with a median age of 57 years. Fifty-five patients (43%) had a single metastasis. Seventy-one patients (55%) received chemotherapy, 58 patients (45%) received biologic agents, and 36 patients (28%) received prior whole brain radiation therapy (WBRT). The median marginal dose was 18.8 Gy (range 12 to 24 Gy). RESULTS Actuarial survival was 52%, 26%, and 13% at 6, 12, and 24 months, respectively. The median survival time was 6.7 months. Local tumor control was 95%, 81% 53% at 6, 12, and 24 months, respectively. The median time to LBF was 25.2 months. Freedom from distant brain failure was 40%, 29%, and 10% at 6, 12, and 24 months, and the median time to DBF was 4.6 months. At the time of data analysis, 108 patients (84%) had died. Fifty-eight patients (52%) died from neurologic death. The median time to neurologic death from GK treatment was 7.9 months. Multivariate analysis revealed that hemorrhage of metastases prior to GK (P = .02) and LBF (P = .03) were the dominant predictors of neurologic death. CONCLUSIONS GK achieves excellent local control and may improve outcomes as a component of a multidisciplinary treatment strategy. Distant brain failure and neurologic demise remain problematic and prospective trials are necessary.

Abstract
Metastatic disease to the brain is a frequent manifestation of melanoma and is associated with significant morbidity and mortality and poor prognosis. Surgery and stereotactic radiosurgery provide local control but less frequently affect the overall outcome of melanoma brain metastases (MBM). The role of systemic therapies for active brain lesions has been largely underinvestigated, and patients with active brain lesions are excluded from the vast majority of clinical trials. The advent of active systemic therapy has revolutionized the care of melanoma patients, but this benefit has not been systematically translated into intracranial activity. In this article, we review the biology and clinical outcomes of patients with MBM, and the evidence supporting the use of radiation, surgery, and systemic therapy in MBM. Prospective studies that included patients with active MBM have shown clinical intracranial activity that parallels systemic activity and support the inclusion of patients with active MBM in clinical trials involving novel agents and combination therapies.

Abstract
BACKGROUND Patients with malignant melanoma may develop brain metastases during the course of the disease, requiring radiotherapeutic treatment. In patients with 1-3 brain metastases, radiosurgery has been established as a treatment option besides surgery. For patients with 4 or more brain metastases, whole brain radiotherapy is considered the standard treatment. In certain patients with brain metastases, radiation treatment using whole brain helical Tomotherapy with integrated boost and hippocampal-sparing may improve prognosis of these patients. METHODS/DESIGN The present prospective, randomized two-armed trial aims to exploratory investigate the treatment response to conventional whole brain radiotherapy applying 30 Gy in 10 fractions versus whole brain helical Tomotherapy applying 30 Gy in 10 fractions with an integrated boost of 50 Gy to the brain metastases as well as hippocampal-sparing in patients with brain metastases from malignant melanoma. The main inclusion criteria include magnetic resonance imaging confirmed brain metastases from a histopathologically confirmed malignant melanoma in patients with a minimum age of 18 years. The main exclusion criteria include a previous radiotherapy of the brain and not having recovered from acute high-grade toxicities of prior therapies. The primary endpoint is treatment-related toxicity. Secondary endpoints include imaging response, local and loco-regional progression-free survival, overall survival and quality of life.

Abstract
PURPOSE To determine prognostic factors that allow the selection of melanoma patients with advanced intra- and extracerebral metastatic disease for palliative whole-brain radiation therapy (WBRT) or best supportive care. METHODS AND MATERIALS This was a retrospective study of 87 patients who underwent palliative WBRT between 1988 and 2009 for progressive or multiple cerebral metastases at presentation. Uni- and multivariate analysis took into account the following patient- and tumor-associated factors: gender and age, Karnofsky performance status (KPS), neurologic symptoms, serum lactate dehydrogenase (LDH) level, number of intracranial metastases, previous resection or stereotactic radiosurgery of brain metastases, number of extracranial metastasis sites, and local recurrences as well as regional lymph node metastases at the time of WBRT. RESULTS In univariate analysis, KPS, LDH, number of intracranial metastases, and neurologic symptoms had a significant influence on overall survival. In multivariate survival analysis, KPS and LDH remained as significant prognostic factors, with hazard ratios of 3.3 (95% confidence interval [CI] 1.6-6.5) and 2.8 (95% CI 1.6-4.9), respectively. Patients with KPS ≥70 and LDH ≤240 U/L had a median survival of 191 days; patients with KPS ≥70 and LDH >240 U/L, 96 days; patients with KPS <70 and LDH ≤240 U/L, 47 days; and patients with KPS <70 and LDH >240 U/L, only 34 days. CONCLUSIONS Karnofsky performance status and serum LDH values indicate whether patients with advanced intra- and extracranial tumor manifestations are candidates for palliative WBRT or best supportive care.

Abstract
The effectivenes of cancer vaccines in inducing CD8(+) T-cell responses remains a challenge, resulting in a need for testing more potent adjuvants. Our objective was to determine the safety and immunogenicity of vaccination against melanoma-related antigens employing MART-1, gp100, and tysosinase paptides combined with the TLR9 agonist PF-3512676 and local granulocyte macrophage-colony stimulating factor in oil emulsion. Using continuous monitoring of safety and a 2-stage design for immunologic efficacy, 20 immune response evaluable patients were targetted. Vaccinations were given subcutaneously on days 1 and 15 per cycle (1cycle=28 d) for up to 13 cycles. Interferon-γ enzyme-linked immunosorbent spot was used as the primary assay measuring the frequency of peripheral antigen-specific CD8(+) T cells at days 50 and 90 compared with baseline (target ≥ 9/20 immunologic responses). Clinical responses were measured by Response Evaluation Criteria In Solid Tumors every 8 weeks. Twenty-two (including 20 immune response evaluable) melanoma patients were enrolled. All had American Joint Committe on Cancer stage IV (5M1a, 6M1b, 11M1c) and most had previously received therapy. Eight had previously treated brain metastases. An average of 3.5 cycles of vaccination per patient was administered. Clinical response data were available for 21 patients. There were 2 partial response and 8 stable disease lasting 2-7 months. One patient with ongoing partial response continued on treatment. At a median follow-up of 7.39 months (range, 3.22-20.47 mo), median progression-free survival was 1.9 months (90% confidence interval, 1.84-3.68) and median overall survival was 13.4 months (90% confidence interval,11.3-∞). No regimen-related grade 3/4/5 toxicities were observed. There were 9/20 patients with positive enzyme-linked immunosorbent spot at day 50 and/or day 90. Our adjuvant regimen combining PF-3512676 and granulocyte macrophage-colony stimulating factor was safe and is worthy of further testing with these or alternative peptides, potentially in combination with antibodies that target immunoregulatory checkpoints.

Abstract
BACKGROUND To retrospectively access outcome and toxicity of whole brain radiotherapy (WBRT) in patients with multiple brain metastases (BM) from malignant melanoma (MM). PATIENTS AND METHODS Results of 87 patients (median age 58 years; 35 female, 52 male) treated by WBRT for BM of MM between 2000 and 2011 were reviewed. Total dose applied was either 30 Gy in 10 fractions (n = 56) or 40 Gy in 20 fractions (n = 31). All but 9 patients suffered from extra-cerebral metastases. Prior surgical resection of BM was performed in 18 patients, salvage stereotactic radiosurgery in 13 patients. RESULTS Mean follow-up was 8 months (range, 0-57 months), the 6- and 12-months overall-(OS) survival rates were 29.2% and 16.5%, respectively. The median OS was 3.5 months. In cerebral follow-up imaging 6 (11) patients showed a complete (partial) remission, while 11 (17) patients had stable disease (intra-cerebral tumor progression). In comparison of total dose, the group treated with 40 Gy in 20 fractions achieved a significant longer OS (p = 0.003, median 3.1 vs. 5.6 months). Furthermore, DS-GPA score (p < 0.001) as well as RPA class (p < 0.001) influenced significantly on OS and patients had a significantly longer OS after surgical resection (p = 0.001, median 3.0 vs. 5.8 months, multivariate p = 0.007). Having extra-cerebral metastases didn't significantly impact on OS (p = 0.21). CONCLUSION Treatment of BM from MM with WBRT is tolerated well and some remissions of BM could be achieved. An advantage for higher treatment total doses was seen. However, outcome is non-satisfying, and further improvements in treatment of BM from MM are warranted.

Abstract
The authors present the case of a 73-year-old lady presenting with weight loss, personality changes, transient confusion and visual loss, 38 years after initial surgical excision of a melanoma of the neck. CT and MRI of the brain showed cerebral metastases and positron emission tomography (PET)-CT showed an additional fludeoxyglucose avid lesion in the lung, which was biopsied. Histology confirmed metastatic malignant melanoma. She declined whole brain radiotherapy in favour of best supportive care and died 4 months after diagnosis. Life-long vigilance among patients with previous melanoma and awareness among physicians are necessary if late recurrences are to be recognised early, and outcomes improved. New imaging techniques including PET-CT may be helpful in diagnosing and staging melanoma recurrence. Treatment options for patients presenting with distant metastases are limited and the prognosis remains poor.

Abstract
BACKGROUND Melanoma that metastasizes to distant sites is associated with a grave prognosis. The objectives of the study were (1) to identify predictive factors for the development of brain metastases from the time of diagnosis of stage III/IV disease, (2) to identify predictive factors for the development of central nervous system (CNS) metastases from the time of diagnosis of primary melanoma, and (3) to assess whether the incidence of brain metastasis is more frequent in patients who had no tumor response to systemic therapy for stage III/IV disease compared with those who had partial or complete response. PATIENTS AND METHODS We collected and retrospectively analyzed information of 740 patients with advanced metastatic melanoma treated at MD Anderson Cancer Center over 15 years. Three hundred and twenty-nine patients had CNS metastases. The characteristics of these patients in terms of median age, sex, primary site, Breslow thickness, stage at first visit, baseline serum parameters, and response to systemic therapy were compared with those of patients who did not develop CNS metastasis. Cox proportional hazards models were used to analyze the cause-specific hazard function for CNS metastasis and deaths without CNS metastasis. RESULTS We identified that M-stage [stage M1b vs. stage III or M1a, hazard ratio (HR)=2.64; stage M1c vs. stage III or M1a, HR=2.13, P<0.0001] and lactic acid dehydrogenase (LDH) (elevated vs. normal LDH, HR=1.51, P<0.001) at diagnosis of unresectable stage III/IV disease can independently predict the risk of developing CNS metastasis from the time of diagnosis of stage III/IV disease. Older age (HR=1.01, P=0.076), chemoresistance (stable disease+progressive disease vs. complete response+partial response HR=2.91, P<0.0001), low level of albumin (vs. normal HR=2.87, P<0.0001), elevated LDH (vs. normal HR=1.55, P=0.0004), and M-stage (M1c disease vs. stage III or M1a HR=1.89, P<0.0001) can independently predict shorter time to death without CNS metastasis from the diagnosis of stage III/IV disease. The location (head and neck vs. limbs HR=1.56, P=0.028; trunk and abdomen vs. limbs HR=1.45, P=0.029; unknown site vs. limbs HR=8.43, P=0.036) and pathology [Clark level (CL)=3 and/or BR2 to 4 mm vs. CL≤2 and/or BR<2 mm HR=1.60, P=0.037; CL>3 and/or BR> 4 mm vs. CL≤2 and/or BR<2 mm HR=2.03, P=0.001) of the primary melanoma can independently predict CNS metastasis-free interval from the time of diagnosis of primaries. Age (HR=1.012, P=0.034) and pathology of the primary melanoma (CL>3 and/or BR>4 mm vs. CL≤2 and/or BR<2 mm HR=1.54, P=0.024) can independently predict time to death without CNS metastasis from primaries. CONCLUSION We identified the predictive factors associated with the development of CNS metastasis in patients with unresectable metastatic melanoma.

Abstract
The prevention and treatment of brain metastases is an increasingly important challenge in oncology. Improved understanding of the molecular pathogenesis of a number of cancers has led to the development of highly active targeted therapies for patients with specific oncogenic events. Such therapies include EGFR inhibitors for lung cancer, HER2/neu inhibitors for breast cancer, and BRAF inhibitors for melanoma. This review will discuss the development of these targeted therapy approaches, existing data about their role in the management of brain metastasis, and opportunities and challenges for future research in this critical area.

Abstract
Disseminated metastatic disease, including brain metastases, is commonly encountered in malignant melanoma. The classical treatment approach for melanoma brain metastases has been neurosurgical resection followed by whole brain radiotherapy. Traditionally, if lesions were either too numerous or surgical intervention would cause substantial neurologic deficits, patients were either treated with whole brain radiotherapy or referred to hospice and supportive care. Chemotherapy has not proven effective in treating brain metastases. Improvements in surgery, radiosurgery, and new drug discoveries have provided a wider range of treatment options. Additionally, recently discovered mutations in the melanoma genome have led to the development of "targeted therapy." These vastly improved options are resulting in novel treatment paradigms for approaching melanoma brain metastases in patients with and without systemic metastatic disease. It is therefore likely that improved survival can currently be achieved in at least a subset of melanoma patients with brain metastases.

Abstract
The outlook for metastatic melanoma to the brain is dismal. New therapeutic avenues are therefore needed. The anti-metastatic mechanisms that may underpin the effects of low molecular weight heparins (LMWHs) in in vitro and preclinical melanoma models warrant translating to a clinical setting. This review outlines a rationale that supports our proposal that metastatic melanoma to the brain is a clinical setting in which to study the anti-metastatic potential of LMWHs. Prevention or delay of brain metastases in melanoma is a clinically relevant and measurable target. Studies to explore the effect of anticoagulants on cancer survival are underway in other malignancies such as lung, pancreas, ovary, breast, and stomach cancer. However, no study to our knowledge has a methodology that could produce clinical evidence in support of a mechanism for whatever benefit may be seen. The setting we propose would allow translation of the molecular knowledge of the metastatic pathways mediated by platelets and the selectins—all potential targets of heparin—in a “time to appearance” of brain metastases endpoint. Since brain metastases are so common and they have a singularly adverse impact on survival, the “biological neuroprotection” model we propose in metastatic melanoma could provide the translational evidence to support the benefit of LMWHs in melanoma. More significantly, this would open the door to a wider “anti-metastatic” approach that could have much greater impact in patients with minimal disease being treated in adjuvant settings for the more common malignancies such as breast and colon cancer.

Abstract
AbstractBackground:We present a rare case of primary mucosal melanoma of the middle ear imaged with 18F-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (FDG-PET/CT).Method:Clinical, radiological, intra-operative and histological findings are discussed.Results:An 88-year-old woman presented with intermittent otorrhoea of the left ear for several months. Otoscopy revealed a livid protrusion of the tympanic membrane. Melanoma was not suspected initially, but was established on transmembranous biopsy. Pre-operative 18F-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography revealed a mass lesion in the left tympanic cavity with high fluoro-deoxyglucose uptake, as well as an ipsilateral intraparotid lymph node metastasis. The patient underwent surgical treatment. The diagnosis of melanoma was confirmed histologically.Conclusion:In this rare case, clinical, radiological and surgical findings led to the diagnosis of a primary mucosal melanoma of the middle ear.

Abstract
Metastasis accounts for the vast majority of morbidity and mortality associated with melanoma. Evidence suggests melanoma has a predilection for metastasis to particular organs. Experimental analyses have begun to shed light on the mechanisms regulating melanoma metastasis and organ specificity, but these analyses are complicated by observations of metastatic dormancy and dissemination of melanocytes that are not yet fully malignant. Additionally, tumor extrinsic factors in the microenvironment, both at the site of the primary tumor and the site of metastasis, play important roles in mediating the metastatic process. As metastasis research moves forward, paradigms explaining melanoma metastasis as a step-wise process must also reflect the temporal complexity and heterogeneity in progression of this disease. Genetic drivers of melanoma as well as extrinsic regulators of disease spread, particularly those that mediate metastasis to specific organs, must also be incorporated into newer models of melanoma metastasis.

Abstract
Of all primary cancers in humans, melanoma has the highest propensity to metastasize to the brain. The prognosis of patients with this disease is extremely poor. Due to its radioresistance and poor response to existing chemotherapeutic regimes, no treatment options other than surgical extirpation, when feasible, have been shown to be effective. An understanding of the underlying tumor biology therefore remains the cornerstone of offering new hope in the treatment. In this review, we comment on the current treatment strategies for melanoma brain metastases and summarize some recent experimental findings from our laboratory with potential for the development of target specific antitumor therapies.

Abstract
BACKGROUND Brain metastasis is common in patients with malignant melanoma and represents a significant cause of morbidity and mortality. Nearly 37% of patients with malignant melanoma eventually develop brain metastasis, and autopsy reports show that 75% of those who died of this disease developed brain metastasis. METHODS We review the level I and level II evidence that guides indications for treatment with surgery, stereotactic radiosurgery, chemotherapy, and immunotherapy for patients with melanoma brain metastasis. RESULTS Level I evidence supports the role of whole brain radiotherapy, microsurgery, and radiosurgery alone or in combination for the treatment of patients with melanoma brain metastasis. Chemotherapy has been ineffective. Ongoing studies continue to assess the effects of immunotherapy and agents in development. CONCLUSIONS Brain metastasis is a common and formidable challenge in patients with malignant melanoma. Although there have been no randomized controlled trials exclusively in patients with melanoma brain metastasis, care can be guided by the application of level I evidence for the treatment of brain metastasis in general and phase II studies focusing specifically on melanoma brain metastasis. Promising new agents and approaches are needed and will hopefully be identified in the near future.

Abstract
BACKGROUND This systematic review examines the role of temozolomide in patients with metastatic melanoma. Outcomes of interest include response rate, progression-free survival, overall survival, quality of life, and adverse effects. METHODS The MEDLINE, EMBASE, and Cochrane Library databases were searched from 1980 through to 2005 using variations on the search terms: melanoma, clinical trial, random, temozolomide, temodal, and temodar. The American Society of Clinical Oncology Annual Meeting proceedings were searched from 1996 to 2005. Relevant articles and abstracts were selected and reviewed by two reviewers, and the reference lists from these sources were searched for additional trials. RESULTS Two randomized phase III trials and three randomized phase II trials were located. In addition, 21 phase I or II trials investigating single-agent temozolomide, temozolomide plus interferon-alpha, and temozolomide plus thalidomide were reviewed. A direct comparison of temozolomide and dacarbazine demonstrated equal efficacy for response rates and overall survival; however, no significant difference was reported. A second phase III study comparing single-agent temozolomide with temozolomide combined with interferon-alpha indicated a significantly higher response rate for the combination treatment arm, but no difference in overall survival was noted. Further phase III studies are required to confirm whether there is a benefit associated with the combination of temozolomide and interferon-alpha or thalidomide. CONCLUSION Our review of the available literature suggests that temozolomide demonstrates comparable activity to the current standard treatment, dacarbazine, with the additional benefit of being a convenient oral treatment that penetrates the blood-brain barrier.

Abstract
BACKGROUND Brain metastases are an alarming complication of advanced melanoma, frequently contributing to patient demise. The authors performed a retrospective analysis to determine whether the treatment of metastatic melanoma with biochemotherapy would result in similar outcomes if brain metastases were first controlled with aggressive, central nervous system (CNS)-directed treatment. METHODS Seventy melanoma patients were treated with biochemotherapy for metastatic melanoma between 1999 and 2005. Of these, 20 patients had recently diagnosed brain metastases, whereas 50 did not. Brain metastases (if present) were treated with stereotactic radiosurgery >or=28 days prior to systemic therapy. All patients were treated with biochemotherapy consisting of either dacarbazine or temozolomide in combination with a 96-hour continuous intravenous infusion of interleukin-2 and subcutaneous interferon-alpha-2B. The primary endpoint was survival from the time of the initial diagnosis of metastatic disease. RESULTS Median survival from the time of the diagnosis of metastatic melanoma was 15.8 months for patients with brain metastases and 11.1 months for those without CNS involvement (P = .26 by the log-rank test; P = .075 by the Gehan Wilcoxon test). Dacarbazine-based and temozolomide-based regimens appeared similar with regard to their effect on overall survival and CNS disease progression. A plateau in further brain recurrences was observed in patients who survived for > 20 months. CONCLUSIONS Data from the current study suggest that the outcome of biochemotherapy is comparable in patients with and those without brain metastases, if brain metastases are controlled with multidisciplinary treatment. Prolonged survival can be achieved in approximately 15% of patients, regardless of whether or not brain metastases are present.
