Abstract
Melanin possess radioprotective and scavenging properties, and its presence can affect the behavior of melanoma cells, its surrounding environment and susceptibility to the therapy, as showed in vitro experiments. To determine whether melanin presence in melanoma affects the efficiency of radiotherapy (RTH) we evaluated the survival time after RTH treatment in metastatic melanoma patients (n = 57). In another cohort of melanoma patients (n = 84), the relationship between melanin level and pT and pN status was determined. A significantly longer survival time was found in patients with amelanotic metastatic melanomas in comparison to the melanotic ones, who were treated with either RTH or chemotherapy (CHTH) and RTH. These differences were more significant in a group of melanoma patients treated only with RTH. A detailed analysis of primary melanomas revealed that melanin levels were significantly higher in melanoma cells invading reticular dermis than the papillary dermis. A significant reduction of melanin pigmentation in pT3 and pT4 melanomas in comparison to pT1 and T2 tumors was observed. However, melanin levels measured in pT3-pT4 melanomas developing metastases (pN1-3, pM1) were higher than in pN0 and pM0 cases. The presence of melanin in metastatic melanoma cells decreases the outcome of radiotherapy, and melanin synthesis is related to higher disease advancement. Based on our previous cell-based and clinical research and present research we also suggest that inhibition of melanogenesis can improve radiotherapy modalities. The mechanism of relationship between melanogenesis and efficacy of RTH requires additional studies, including larger melanoma patients population and orthotopic, imageable mouse models of metastatic melanoma.

Abstract
Routine light microscopy remains a powerful tool to diagnose, stage and prognose melanoma. Although it is very economical and efficient, it requires a significant level of expertise and, in difficult cases the final diagnosis is affected by subjective interpretation. Fortunately, new insights into the genomic aberrations characteristic of melanoma, coupled with ancillary studies, are further refining evaluation and management allowing for more confident diagnosis, more accurate staging and the selection of targeted therapy. In this article, we review the standard of care and new updates including four probe FISH, the 2009 American Joint Commission on Cancer staging of melanoma and mutant testing of melanoma, which will be crucial for targeted therapy of metastatic melanoma.

Abstract
Previously, a 54% 5-year survival was reported for metastatic melanoma patients treated with patient-specific vaccines consisting of autologous dendritic cells loaded with antigens from autologous proliferating tumor cells. This study attempted to determine which clinical and laboratory factors best explained long-term survival in this group of patients. Univariate analyses were used to identify factors associated with continuous survival after initiating vaccine therapy. Multivariate logistic regression was used to identify independent factors to classify survival at 3.5 years. Survivors were followed a minimum of 3.7 years (median: 5.7). Univariate analyses identified eight features associated with improved survival: Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0, no measurable disease at study entry, receiving 8 vaccinations, age <50 years, normal baseline lactate dehydrogenase, no history of visceral metastases, anergy to standard skin tests, and failure of interferon-gamma (IFN-γ) to induce apoptosis in autologous tumor cells. After examining 54 variables for which complete information was available over all patients, the best multivariate regression for survival at 3.5 years utilized six features: prior radiation therapy, younger age, male gender, ECOG PS 0, higher numbers of cells administered during the first 3 injections, and lower numbers of viable cells administered during the first 3 injections. This model correctly classified survival for 28 of 32 patients (87%) and death for 20 of 22 (91%). When features with incomplete information were included in the analysis, addition of IFN-γ-induced apoptosis (n=49) improved predictive accuracy to 27 of 29 (93%) for survival and 19 of 20 (95%) for death. Dependencies between variables were common, but these multivariate linear models yielded high classification accuracy for survival at 3.5 years and identified two features of the vaccine itself as being of independent significance.

Abstract
Melanoma accounts for only a small portion of skin cancer but it is associated with high mortality. Melanoma serum biomarkers that may aid early diagnosis or guide therapy are needed clinically. However, studies of serum biomarkers have often been hampered by the serum interference that causes false readouts in immunological tests. Here we show that, after using a special buffer to eliminate the serum interference, IL-8 and cathepsin B levels were significantly elevated in melanoma patients (p < 0.05). More importantly, the combination of IL-8 and cathepsin B were also studied as a prognosis marker for melanoma mortality. Our study provides a novel approach to examine serum biomarkers.

Abstract
Although melanoma is one of the most studied malignancies, it still remains challenging for biomedicine. Since aberrant glycosylation has been considered as an important hallmark of cancer for many years, melanoma glycomic studies give a chance of better understanding the biology of the disease. The multistage nature of melanoma development, which is accompanied by changes in the expression of adhesion receptors from the integrin family, provides a chance for searching for neoglycoforms of proteins that can be considered as future sensitive melanoma biomarkers. The β1,6-branching, sialylation and fucosylation seem to be important modifications of integrin N-glycans in the case of malignant melanoma progression.

Abstract
Detecting malignant melanoma at an early stage, monitoring therapy, predicting recurrence and identifying patients at risk for metastasis continue to be a challenging and demanding objective. The last two decades have witnessed innovations in the field of melanoma biomarkers. However, global agreement concerning monitoring and early detection has yet to be reached. This is a review of the current literature regarding melanoma biomarkers including demographic, clinical, pathological and molecular biomarkers that are produced by melanoma or non-melanoma cells. A number of these biomarkers demonstrate promising results as possible methods for early detection, predicting recurrence and monitoring therapy. Other biomarkers appear to be promising for identifying patients at risk for metastasis. We reviewed the most pertinent information in the field thus far and how this knowledge can impact, or not, the management of melanoma patients prognostically and therapeutically.

LDH correlation with survival in advanced melanoma from two large, randomised trials (Oblimersen GM301 and EORTC 18951). Eur J Cancer 2009; 45:1807-14. [PMID: 19419855 DOI: 10.1016/j.ejca.2009.04.016] [Citation(s) in RCA: 104] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2009] [Accepted: 04/09/2009] [Indexed: 01/03/2023]
Abstract
PURPOSE In a randomised study (GM301; dacarbazine with/without oblimersen), patients with advanced melanoma were stratified based on performance status, metastatic site and lactate dehydrogenase (LDH). Progression-free survival and response and durable response rates showed a highly significant difference favouring dacarbazine-oblimersen and a nearly significant survival difference. All efficacy parameters significantly favoured dacarbazine-oblimersen in patients with normal baseline LDH [1.1xupper limit of normal (ULN)]. Each stratification factor was assessed for an interaction with treatment on survival and an interaction was detected only for LDH. EXPERIMENTAL DESIGN Baseline LDH values in Study GM301 treatment groups were combined and analysed using cutoffs above and below 1xULN. Baseline LDH in EORTC study 18951 (dacarbazine, cisplatin, interferon-alfa-2b with/without interleukin-2 in advanced melanoma) was independently analysed using the same approach. In Study GM301, the relation between treatment effect and LDH, treatment effect and tumour size, LDH and tumour size and LDH and disease site were determined. RESULTS In Study GM301 (N=760) and Study 18951 (N=325), LDH was within the upper range of normal for a large number of patients. This was not exhibited in the general population, suggesting such values may be elevated rather than normal in melanoma. A highly ordered and monotonic relationship was apparent between LDH and survival: survival worsened as LDH became more elevated, even when LDH remained within normal range. LDH and tumour size were poorly correlated; elevated LDH was not associated with any one disease site. LDH was highly predictive of oblimersen effect. CONCLUSION In designing studies, LDH should be considered, regardless of tumour size or disease site.

Abstract
High mortality rate for metastatic melanoma is related to its resistant to the current methods of therapy. Melanogenesis is a metabolic pathway characteristic for normal and malignant melanocytes that can affect the behavior of melanoma cells or its surrounding environment. Human melanoma cells in which production of melanin pigment is dependent on tyrosine levels in medium were used for experiments. Peripheral blood mononuclear cells were derived from the buffy coats purchased from Lifeblood Biological Services. Cell pigmentation was evaluated macroscopically, and tyrosinase activity was measured spectrophotometrically. Cell proliferation and viability were measured using lactate dehydrogenase release MTT, [(3)H]-thymidine incorporation and DNA content analyses, and gene expression was measured by real time RT-PCR. Pigmented melanoma cells were significantly less sensitive to cyclophosphamide and to killing action of IL-2-activated peripheral blood lymphocytes. The inhibition of melanogenesis by either blocking tyrosinase catalytic site or chelating copper ions sensitized melanoma cells towards cytotoxic action of cyclophosphamide, and amplified immunotoxic activities of IL-2 activated lymphocytes. Exogenous L-DOPA inhibited lymphocyte proliferation producing the cell cycle arrest in G1/0 and dramatically inhibited the production of IL-1beta, TNF-alpha, IL-6 and IL-10. Thus, the active melanogenesis could not only impair the cytotoxic action of cyclophosphamid but also has potent immunosuppressive properties. This resistance to a chemotherapeutic agent or immunotoxic activity of lymphocytes could be reverted by the action of tyrosinase inhibitors. Thus, the inhibition of melanogenesis might represent a valid therapeutic target for the management of advanced melanotic melanomas.

Abstract
This article reviews current evidence on epidemiology, diagnosis and management of cutaneous melanoma. Incidence of cutaneous melanoma is rising in all Caucasian populations across the world; thus, melanoma represents a significant public health burden. Although, incidence of melanoma is in continuous increase, a decrease of mortality and improved survival has been observed in most western European populations. Clinical characteristics of four major types of melanoma (superficial spreading, nodular, lentigo maligna melanoma and acral lentiginous melanoma) have been described. Surgical removal of melanoma remains the standard care in all primary melanomas. Current evidence suggests use of 1 to 2 cm excision margins. Wider margins may be necessary in patients with thicker melanomas with higher risk for local recurrence. In the treatment of regional lymph nodes elective lymphadenectomy has been surpassed by the sentinel lymph node biopsy (SLNB). However, although prognostic value of SLNB has been confirmed, its therapeutical benefit still needs to be evaluated. Currently there is no standard adjuvant therapy for melanoma although interferon-alpha has been the most widely used treatment in the adjuvant setting. The role of metastasectomy (removal of distant metastases) is still controversial. Chemotherapeutic agents have a limited activity in patients with metastatic melanoma with response rates up to 25%. Although different vaccines have been tested in melanoma patients their role still remain to be established in phase III trials. Progresses in molecular biology and genetics of melanoma may lead to the development of novel melanoma therapies.

Abstract
Molecular pathology is rapidly evolving, featuring continuous technologic improvements that offer novel clinical opportunities for the recognition of disease predisposition, for identifying sub-clinical disease, for more accurate diagnosis, for selecting efficacious and non-toxic therapy, and for monitoring of disease outcome. Currently, the identification and prognosis of primary cutaneous melanoma is based on histologic factors (tumor depth and ulceration) and clinical factors (number of lymph node and/or distant metastases). However, metastasis can occur in patients with thin melanomas, and sentinel lymph node biopsy does not identify all patients at risk for distant metastasis. New markers exist that correlate with melanoma progression, which may aid in melanoma identification, prognostication, and detection of minimal residual disease/early recurrence. Moreover, not many therapeutic options exist for melanoma as no regimen prolongs survival. Emerging data with investigational therapies suggest that certain markers might play a crucial role in identifying patients who will respond to therapy or show utility in the monitoring the response to therapy. Herein, molecular diagnostics that can potentially benefit the individual melanoma patient will be discussed.
