Abstract
BACKGROUND Malignant melanoma, one of the most aggressive of all skin cancers, is increasing in incidence throughout the world. Surgery remains the cornerstone of curative treatment in earlier stages. Metastatic disease is incurable in most affected people, because melanoma does not respond to most systemic treatments. A number of novel approaches are under evaluation and have shown promising results, but they are usually associated with increased toxicity and cost. The combination of chemotherapy and immunotherapy has been reported to improve treatment results, but it is still unclear whether evidence exists to support this choice, compared with chemotherapy alone. No language restrictions were imposed. OBJECTIVES To compare the effects of therapy with chemotherapy and immunotherapy (chemoimmunotherapy) versus chemotherapy alone in people with metastatic malignant melanoma. SEARCH METHODS We searched the Cochrane Skin Group Specialised Register (14 February 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2005), MEDLINE (2003 to 30 January 2006 ), EMBASE (2003 to 20 July 2005) and LILACS (1982 to 20 February 2006). References, conference proceedings, and databases of ongoing trials were also used to locate trials. SELECTION CRITERIA All randomised controlled trials that compared the use of chemotherapy versus chemoimmunotherapy on people of any age, diagnosed with metastatic melanoma. DATA COLLECTION AND ANALYSIS Two authors independently assessed each study to determine whether it met the pre-defined selection criteria, with differences being resolved through discussion with the review team. Two authors independently extracted the data from the articles using data extraction forms. Quality assessment included an evaluation of various components associated with biased estimates of treatment effect. Whenever possible, a meta-analysis was performed on the extracted data, in order to calculate a weighed treatment effect across trials. MAIN RESULTS Eighteen studies met our criteria and were included in the meta-analysis, with a total of 2625 participants. We found evidence of an increase of objective response rates in people treated with chemoimmunotherapy, in comparison with people treated with chemotherapy. Nevertheless, the impact of these increased response rates was not translated into a survival benefit. We found no difference in survival to support the addition of immunotherapy to chemotherapy in the systemic treatment of metastatic melanoma, with a hazard ratio of 0.89 (95% CI 0.72 to 1.11, P = 0.31). Additionally, we found increased hematological and non-hematological toxicities in people treated with chemoimmunotherapy. AUTHORS' CONCLUSIONS We failed to find any clear evidence that the addition of immunotherapy to chemotherapy increases survival of people with metastatic melanoma. Further use of combined immunotherapy and chemotherapy should only be done in the context of clinical trials.

Abstract
Intralesional therapy of melanoma patients with locally advanced metastatic disease is attracting increasing interest, not least due to its ability to lead to both direct tumor cell killing and the stimulation of both a local and a systemic immune response. An obvious pre-requisite for this type of approach is the presence of accessible metastases that are amenable to direct injection with the therapeutic agent of interest. Patients who present with these characteristics belong to stages IIIB/C or IV of the disease. Surgical resection with intention to cure is the standard of care for patients with limited tumor burden and confined spread of disease (resectable patients). However, this category of patients is at a high risk of further recurrences until the disease becomes inoperable (unresectable) or progresses to a more advanced stage with visceral organ involvement, after which the prognosis is particularly grim. Most of the intralesional treatments tested so far, including the recently approved oncolytic virus talimogene laherparepvec, target the subpopulation of patients with unresectable disease, but the possibility to use the intralesional treatment in a neoadjuvant setting for fully resectable patients is attracting considerable interest. The present article reviews approved products and advanced stage pharmaceutical agents in development for the intralesional treatment of melanoma patients.

Abstract
Advances in treatment of melanoma with systemic immunotherapies continue, with promising findings for anti-PD-1 agents combined with ipilimumab. Still, an unmet need persists because of populations ineligible for systemic immunotherapies, incomplete cure/response rates, toxicities and extreme costs. Also, potential for effective use of intralesional therapies remains, especially for local regional disease, but also for benefits of local ablation and adjuvant systemic host tumor-specific responses. Clinical trials of T-VEC, PV-10, CAVATAK and electroporation with plasmid IL-12 have demonstrated favorable, durable responses. Initial experience combining T-VEC, the agent furthest along in testing, with ipilimumab revealed higher complete and overall response rates than with either agent alone. Intralesional therapies may offer a treatment tool in the growing therapeutic armamentarium against this lethal disease.

Abstract
BACKGROUND Surgical excision constitutes an important part of the treatment of local advanced malignant melanoma. Due to the high recurrence risk, adjuvant high-dose interferon therapy is still the only therapy used in stage IIB and III high-risk melanoma patients. METHODS One hundred two high-risk malignant melanoma patients who received high-dose interferon-α-2b therapy were evaluated retrospectively. The clinicopathological features, survival times, and prognostic factors of the patients were determined. RESULTS The median disease-free and overall survival times were 25.2 and 60.8 months, respectively. Our findings revealed that male gender, advanced disease stage, lymph node involvement, lymphatic invasion, the presence of ulceration, and a high Clark level were significant negative prognostic factors. CONCLUSION In light of the favorable survival results obtained in this study, high-dose interferon treatment as adjuvant therapy for high-risk melanoma is still an efficient treatment and its possible side effects can be prevented by taking the necessary precautions.

Abstract
PURPOSE OF REVIEW Patients with unresectable, multiple or advanced locally/regionally metastatic stage IIIB/C or stage IV M1a melanoma have a high risk for recurrence, progression and metastasis. The article reviews treatment advances for this population. RECENT FINDINGS After promising phase 2 results with Allovectin-7 (velimogene aliplasmid), overall survival in a phase 3 study was shorter for Allovectin-7 than for dacarbazine/temozolomide (median 18.8 versus 24.1 months).In a phase 2 trial of intratumoral electroporation of plasmid interleukin-12 among 28 patients with advanced melanoma, the primary endpoint of best overall response rate within 24 weeks of first treatment was 32.2% for objective response and 10.7% for complete response.In the phase 3 OPTiM trial of talimogene laherparepvec, the intralesional agent that is furthest along in clinical testing, the primary endpoint of durable response rate was 16% for talimogene laherparepvec and 2% for granulocyte macrophage colony-stimulating factor.In the PV-10 phase 2 trial among 80 patients with stage III-IV melanoma, the overall response rate was 51%, with a 26% complete response rate. SUMMARY Despite advances, many patients will need several lines of therapy. Some will not be eligible for systemic therapy. Their low toxicity, easy administration and likely systemic immune effects make intralesional therapies an attractive option.

Abstract
Tissue non-specific alkaline phosphatase (TNAP) may be involved in the synthesis of GABA and adenosine, which are the main inhibitory neurotransmitters in cortex. We explored this putative TNAP function through electrophysiological recording (local field potential ) in slices of mouse somatosensory cortex maintained in vitro. We used tetramisole, a well documented TNAP inhibitor, to block TNAP activity. We expected that inhibiting TNAP with tetramisole would lead to an increase of neuronal response amplitude, owing to a diminished availability of GABA and/or adenosine. Instead, we found that tetramisole reduced neuronal response amplitude in a dose-dependent manner. Tetramisole also decreased axonal conduction velocity. Levamisole had identical effects. Several control experiments demonstrated that these actions of tetramisole were independent from this compound acting on TNAP. In particular, tetramisole effects were not stereo-specific and they were not mimicked by another inhibitor of TNAP, MLS-0038949. The decrease of axonal conduction velocity and preliminary intracellular data suggest that tetramisole blocks voltage-dependent sodium channels. Our results imply that levamisole or tetramisole should not be used with the sole purpose of inhibiting TNAP in living excitable cells as it will also block all processes that are activity-dependent. Our data and a review of the literature indicate that tetramisole may have at least four different targets in the nervous system. We discuss these results with respect to the neurological side effects that were observed when levamisole and tetramisole were used for medical purposes, and that may recur nowadays due to the recent use of levamisole and tetramisole as cocaine adulterants.

Abstract
Co-delivery is a rapidly growing sector of drug delivery that aspires to enhance therapeutic efficacy through controlled delivery of diverse therapeutic cargoes with synergistic activities. It requires the design of carriers capable of simultaneously transporting to and releasing multiple therapeutics at a disease site. Co-delivery has arisen from the emerging trend of combination therapy, where treatment with two or more therapeutics at the same time can succeed where single therapeutics fail. However, conventional combination therapy offers little control over achieving an optimized therapeutic ratio at the target site. Co-delivery via inclusion of multiple therapeutic cargos within the same carrier addresses this issue by not only ensuring delivery of both therapeutics to the same cell, but also offering a platform for control of the delivery process, from loading to release. Co-delivery systems have been formulated using a number of carriers previously developed for single-therapeutic delivery. Liposomes, polymeric micelles, PLGA nanoparticles, and dendrimers have all been adapted for co-delivery. Much of the effort focuses on dealing with drugs having dissimilar properties, increasing loading efficiencies, and controlling loading and release ratios. In this review, we highlight the innovations in carrier designs and formulations to deliver combination cargoes of drug/drug, drug/siRNA, and drug/pDNA toward disease therapy. With rapid advances in mechanistic understanding of interrelating molecular pathways and development of molecular medicine, the future of co-delivery will become increasingly promising and prominent.

Abstract
The majority of skin cancers of the head and neck are nonmelanoma skin cancers (NMSC). Basal cell carcinoma and squamous cell carcinoma are the most frequent types of NMSC. Malignant melanoma is an aggressive neoplasm of skin, and the ideal adjuvant therapy has not yet been found, although various options for treatment of skin cancer are available to the patient and physician, allowing high cure rate and excellent functional and cosmetic outcomes. Sunscreen protection and early evaluation of suspicious areas remain the first line of defense against skin cancers.

Abstract
Immunotherapy is an important modality in the therapy of patients with malignant melanoma. As our knowledge about this disease continues to expand, so does the immunotherapeutic armamentarium. Nevertheless, successful preclinical models do not always translate into clinically meaningful results. The authors give a comprehensive analysis of most recent advances in the immune anti-melanoma therapy, including interleukins, interferons, other cytokines, adoptive immunotherapy, biochemotherapy, as well as the use of different vaccines. We also present the fundamental concepts behind various immune enhancement strategies, passive immunotherapy, as well as the use of immune adjuvants. This review brings into discussion the results of newer and older clinical trials, as well as potential limitations and drawbacks seen with the utilization of various immune therapies in malignant melanoma. Development of novel therapeutic approaches, along with optimization of existing therapies, continues to hold a great promise in the field of melanoma therapy research. Use of anti-CTLA4 and anti-PD1 antibodies, realization of the importance of co-stimulatory signals, which translated into the use of agonist CD40 monoclonal antibodies, as well as activation of innate immunity through enhanced expression of co-stimulatory molecules on the surface of dendritic cells by TLR agonists are only a few items on the list of recent advances in the treatment of melanoma. The need to engineer better immune interactions and to boost positive feedback loops appear crucial for the future of melanoma therapy, which ultimately resides in our understanding of the complexity of immune responses in this disease.

Abstract
Induction of tumor-specific immunity is an attractive approach to cancer therapy, however to date every major pivotal trial has resulted in failure. While the phenomena of tumor-mediated immune suppression has been known for decades, only recently have specific molecular pathways been elucidated, and for the first time, rationale means of intervening and observing results of intervention have been developed. In this review we describe major advances in our understanding of tumor escape from immunological pressure and provide some possible therapeutic scenarios for enhancement of efficacy in future cancer vaccine trials.

Abstract
BACKGROUND Because of the poor outcomes for patients with recurrent glioblastoma multiforme (GBM), and some laboratory and clinical evidence of efficacy using interferon in GBM, we assessed the toxicity and efficacy of temozolomide (TMZ) combined with either short-acting (IFN) or long-acting (pegylated) interferon alpha2b (PEG) in two single-arm phase II studies, and compared the results to 6-month progression-free survival (PFS-6) data from historical controls. METHODS Two single-arm phase II studies were carried out in adults with GBM. Patients were treated with the standard regimen of TMZ (150-200 mg m(-2) per day x 5 days every month) combined with either 4 million units per m(2) subcutaneously (SQ) three times weekly of IFN or 0.5 microg kg(-1) SQ weekly of PEG. Physical exams and imaging evaluations were carried out every 8 weeks. RESULTS On the IFN study, 34 adults (74% men) were enrolled, and 29 adults (55% men) on the PEG study; median Karnofsky performance status was 80 and 90 for the IFN and PEG studies, respectively. Grade 3 or 4 toxicities were common, leucopoenia and thrombocytopoenia occurring in 35-38% and 18-21% of patients, respectively. Grade 3 or 4 fatigue occurred in 18% of patients on both studies. Lymphopoenia was infrequent. PFS-6 was 31% for 29 evaluable patients in the IFN study and 38% for 26 evaluable patients in the PEG study. CONCLUSION In recurrent GBM patients, both studies of standard dose TMZ with either IFN or PEG showed improved efficacy when compared to historical controls, or reports using TMZ alone. Even though the TMZ+PEG study met criteria for further study, the results of both of these studies must be considered in light of the standard of care (TMZ plus radiotherapy) for newly diagnosed GBM, which has evolved since the inception of these studies. Despite the results of the current studies being eclipsed by the new GBM standard of care, these results can still inform the development of newer approaches for GBM, either in an earlier, upfront setting, or by extrapolation of the results and consideration of the use of PEG or IFN in conjunction with other antiglioma strategies.

Abstract
The effect of interferon alpha (IFNalpha2) given alone or in combination has been widely explored in clinical trials over the past 30 years. Despite the number of adjuvant studies that have been conducted, controversy remains in the oncology community regarding the role of this treatment. Recently an individual patient data (IPD) meta-analysis at longer follow-up was reported, showing a statistically significant benefit for IFN in relation to relapse-free survival, without any difference according to dosage (p = 0.2) or duration of IFN therapy (p = 0.5). Most interestingly, there was a statistically significant benefit of IFN upon overall survival (OS) that translates into an absolute benefit of at least 3% (CI 1-5%) at 5 years. Thus, both the individual trials and this meta-analysis provide evidence that adjuvant IFNalpha2 significantly reduces the risk of relapse and mortality of high-risk melanoma, albeit with a relatively small absolute improvement in survival in the overall population. We have surveyed the international literature from the meta-analysis (2006) to summarize and assimilate current biological evidence that indicates a potent impact of this molecule upon the tumor microenvironment and STAT signaling, as well as the immunological polarization of the tumor tissue in vivo. In conclusion, we argue that there is a compelling rationale for new research upon IFN, especially in the adjuvant setting where the most pronounced effects of this agent have been discovered. These efforts have already shed light upon the immunological and proinflammatory predictors of therapeutic benefit from this agent--that may allow practitioners to determine which patients may benefit from IFN therapy, and approaches that may enable us to overcome resistance or enhance the efficacy of IFN. Future efforts may well build toward patient-oriented therapy based upon the knowledge of the unique molecular features of this disease and the immune system of each melanoma patient.

Abstract
For many years, various cancer vaccines have been widely evaluated, however clinical responses remain rare. In this review, we attempt to address the question of which delivery strategies and platforms are feasible to produce clinical response and define the characteristics of the strategy that will induce long-lasting antitumor response. We limit our analysis and discussion to microparticles/nanoparticles, liposomes, heat-shock proteins, viral vectors and different types of adjuvants. This review aims to provide an overview of the specific characteristics, strengths and limitations of these delivery systems, focusing on their impacts on the development of melanoma vaccine. To date, only adoptive T-cell transfer has shown promising clinical outcomes compared to other treatments.

Abstract
Early surgical intervention remains the most successful therapy for melanoma. Despite better outcomes observed in soft tissue and lymph node metastases, the results of pharmacological therapies are still disappointing. Currently, there is no standard adjuvant therapy for melanoma. Low concentrations of coenzyme Q10 have been demonstrated in melanoma cell lines and in sera of melanoma patients. These data and the results of clinical trials of patients with other advanced cancers prompted this study of the long-term administration of an optimized dose of recombinant interferon alpha-2b and coenzyme Q10 to patients with stage I and II melanoma. A 3-year trial envisaging uninterrupted treatment with low-dose recombinant interferon alpha-2b (9 000 000 000 IU weekly) administered twice daily and coenzyme Q10 (400 mg/day) was conducted in patients with stage I and II melanoma (American Joint Committee on Cancer criteria 2002) and surgically removed lesions. Treatment efficacy was evaluated as incidence of recurrences at 5 years. All patients completed the treatment and the follow-up. Significantly different rates of disease progression were observed in the interferon+coenzyme Q10 and the interferon group for both stages. No patient withdrew from the study owing to side effects. Long-term administration of an optimized dose of recombinant interferon alpha-2b in combination with coenzyme Q10 seemed to induce significantly decreased rates of recurrence and had negligible adverse effects. A survival study could not be undertaken owing to the small patient sample and the short duration of follow-up.

Abstract
A need for factors predictive of prognosis is present in patients who are diagnosed with malignant melanoma. The detection of circulating melanoma cells by reverse transcriptase-polymerase chain reaction for tyrosinase mRNA is a possible negative prognostic factor. The aim of this study was to assess the prognostic value of reverse transcriptase-PCR for tyrosinase mRNA in peripheral blood samples. From January 2000 to February 2003, duplicate blood samples were drawn from 114 melanoma patients following surgery and informed consent, and were tested with reverse transcriptase-PCR, for tyrosinase mRNA. Outer primers for the first PCR were R1 (sense): TTGGCAGATTGTCTGTAGCC and R2 (antisense): AGGCATTGTGCATGCTGCT. For the second round of PCR, nested primers were R3 (sense): GTCTTTATGCAATGGAACGC and R4 (antisense): GCTATCCCAGTAAGTGGACT. Threshold for detection of the technique was determined by adding serially diluted MelJuSo cells to healthy volunteer blood samples. Overall, 91 (79.1%) patients tested negative for tyrosinase mRNA and 24 (20.9%) tested positive. The number of patients who tested positive by stage was 3/38 (7.9%) for stage I, 3/22 (13.6%) for stage II, 5/30 (16.7%) for stage III and 13/24 (54.2%) for stage IV (P< 0.0001). 11/90 (12.2%) patients with no evidence of disease (stage I, II and III) tested positive and 13/24 (54.2%) patients with clinically confirmed distant metastases (stage IV) tested positive (P<0.00001). With median follow-up of 372 days or to death (range: 0-1303 days), median progression-free survival has not been reached for tyrosinase-negative patients and was 265 days for tyrosinase-positive patients (P<0.00001, log-rank test=21.07). Median overall survival was 344 days for tyrosinase-positive patients and has not been reached for tyrosinase-negative patients (P=0.0001, log-rank test=21.38). Stage, Breslow thickness and result of RT-PCR were significant prognostic factors for disease-free survival in a multivariate analysis, and stage was the only significant prognostic factor for overall survival. In conclusion, detection of circulating melanoma cells by reverse transcriptase-PCR for tyrosinase mRNA is a significant adverse prognostic factor for disease-free survival in patients with malignant melanoma.

Abstract
BACKGROUND Malignant melanoma, one of the most aggressive of all skin cancers, is increasing in incidence throughout the world. Surgery remains the cornerstone of curative treatment in earlier stages. Metastatic disease is incurable in most affected people, because melanoma does not respond to most systemic treatments. A number of novel approaches are under evaluation and have shown promising results, but they are usually associated with increased toxicity and cost. The combination of chemotherapy and immunotherapy has been reported to improve treatment results, but it is still unclear whether evidence exists to support this choice, compared with chemotherapy alone. No language restrictions were imposed. OBJECTIVES To compare the effects of therapy with chemotherapy and immunotherapy (chemoimmunotherapy) versus chemotherapy alone in people with metastatic malignant melanoma. SEARCH STRATEGY We searched the Cochrane Skin Group Specialised Register (14 February 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2005), MEDLINE (2003 to 30 January 2006 ), EMBASE (2003 to 20 July 2005) and LILACS (1982 to 20 February 2006). References, conference proceedings, and databases of ongoing trials were also used to locate trials. SELECTION CRITERIA All randomised controlled trials that compared the use of chemotherapy versus chemoimmunotherapy on people of any age, diagnosed with metastatic melanoma. DATA COLLECTION AND ANALYSIS Two authors independently assessed each study to determine whether it met the pre-defined selection criteria, with differences being resolved through discussion with the review team. Two authors independently extracted the data from the articles using data extraction forms. Quality assessment included an evaluation of various components associated with biased estimates of treatment effect. Whenever possible, a meta-analysis was performed on the extracted data, in order to calculate a weighed treatment effect across trials. MAIN RESULTS Eighteen studies met our criteria and were included in the meta-analysis, with a total of 2625 participants. We found evidence of an increase of objective response rates in people treated with chemoimmunotherapy, in comparison with people treated with chemotherapy. Nevertheless, the impact of these increased response rates was not translated into a survival benefit. We found no difference in survival to support the addition of immunotherapy to chemotherapy in the systemic treatment of metastatic melanoma, with a hazard ratio of 0.89 (95% CI 0.72 to 1.11, p=0.31). Additionally, we found increased hematological and non-hematological toxicities in people treated with chemoimmunotherapy. AUTHORS' CONCLUSIONS We failed to find any clear evidence that the addition of immunotherapy to chemotherapy increases survival of people with metastatic melanoma. Further use of combined immunotherapy and chemotherapy should only be done in the context of clinical trials.

Abstract
Resistance to various antineoplastic agents is common in the clinical management of malignant melanoma. The biological mechanisms conferring these different drug-resistant phenotypes are still unclear. To identify potential factors mediating drug resistance to melanoma cells, the mRNA expression profiles of the parental drug-sensitive human melanoma cell line MeWo and four derived drug-resistant sublines with acquired resistance against four commonly used drugs for melanoma treatment (cisplatin, etoposide, fotemustine and vindesine) were analysed. We investigated cDNA arrays with 43,000 cDNA clones ( approximately 30,000 unique genes) to study the expression patterns of these cell lines. We were able to simultaneously extract new candidate genes associated with drug resistance in malignant melanoma and to correlate the present findings with previously described resistance-associated genes. Using hierarchical clustering and analysing the overlap of genes with altered expression, we detected similarities between the expression signatures related to cisplatin and fotemustine resistance. The resistance against vindesine required a minimal set of changes in gene expression relative to the parental MeWo cell line. Our study provides new data that may be used to obtain further insight into the resistance characteristics of malignant melanoma.

Abstract
BACKGROUND The incidence of cutaneous melanoma has increased during the past three decades. The development of sentinel lymph node biopsy has facilitated better staging. Despite these improvements, 5-year survival rates for American Joint Committee on Cancer stage II and III disease range from 50%-90%. METHODS A review of the current literature concerning adjuvant therapies in patients with stage II and III malignant melanomas was undertaken. RESULTS The focus of adjuvant therapies has shifted from radiotherapy, BCG and levamisole to newer biological agents. Interferon, interleukin and vaccines have been evaluated but none of these agents have demonstrated an increase in overall survival in patients with stage II and III melanoma. Interferon can prolong disease-free interval. CONCLUSION At present, no adjuvant therapy improves overall survival in patients with stage II and III melanoma. New staging allows more accurate stratification of patients for clinical trials.

Abstract
To date, no standard adjuvant therapy have increased overall survival in patients with malignant melanoma (MM). The effect of interferon alpha as a single agent or in combination has been widely explored in clinical trials. Critical reading of the major international randomised trials showed that response to interferon (IFN) in terms of improvement of overall survival (OS) may not be strictly correlated with the used dosage and that duration of therapy may impact disease-free survival (DFS) but not OS. Patients' heterogeneity could be an explanation for the discordant data of the international literature. Indeed, majority of these studies started in late 1980s or early 1990s, when accurate staging procedure were not available yet. The adequate surgical treatment should be considered as an independent variable in the analysis of MM adjuvant protocols. Considering the treatment cost, which is the main goal: DFS, OS or quality of life? Answering these questions is difficult, but some considerations must be taken to put order in this field. Putting together data from all different studies, IFN therapy seems to protect MM patients from recurrences during the entire treatment period and a prolonged IFN therapy seems to improve DFS. The only positive result on OS was demonstrated for high-dose IFN (HD-IFN) in a single study (presenting a relatively short follow-up median) and not confirmed in a subsequent study from the same authors. Considering that low-dose interferon (LD-IFN) is tolerated much better than HD-IFN (about 10% versus more than 70% of cases with grade 3-4 toxicity, respectively), a prolonged LD-IFN (more than 2 years) may represent a reasonable opportunity for MM patients, also considering its advantageous cost-effectiveness. Conversely, considering the improvement of OS as the main target of MM adjuvant therapy, the "wait and watch" attitude remains the only approach to be pursued at present. It is a physician's choice.

Abstract
The natural course of cutaneous melanoma (CM) is determined by its metastatic spread and depends on tumor thickness, ulceration, gender, localization, and the histologic subtype of the primary tumor. CM metastasis develops via three main metastatic pathways and occurs as satellite or in-transit metastasis, as regional lymph node metastasis or as distant metastasis at the time of primary recurrence. About 50% of all CM patients with tumor progression firstly develop regional lymph node metastases. In the other 50% the first metastases are satellite or in-transit metastases (about 20%), or immediately distant metastases (about 30%). Development of distant metastasis appears to be an early event in metastatic spread and may in the majority of cases originate from the primary tumor, only few cases may develop secondarily to locoregional metastasis. Reporting of organ involvement in distant metastasis greatly differs between the results of imaging techniques and autopsy results in respect to the metastatic patterns detected, pointing out that there is a need of improved imaging systems. Proliferation, neovascularization, lymphangiogenesis, invasion, circulation, and embolism are important steps in the pathogenesis of CM metastasis, with tumor vascularity as an important independent significant prognostic factor. The expression of chemokine receptors in cancer cells associated with the expression of the respective chemokine receptor ligands in the target sites of the metastasis is an interesting observation which may stimulate the development of new therapeutic strategies.

Abstract
BACKGROUND The local and systemic effects of bacillus Calmette-Guerin (BCG) have been known for decades. To investigate the adjuvant effect of BCG on resected American Joint Committee on Cancer (AJCC) Stage I-III melanoma, the Eastern Cooperative Oncology Group conducted a large trial to study the use of BCG alone or a combination of BCG and dacarbazine between 1974 and 1978. METHODS A total of 734 patients were randomized to 4 clinical groups consolidated into 2 cohorts. Cohort I compared BCG with observation and Cohort II compared BCG with a combination of BCG and dacarbazine. The primary end points were survival time and time to disease progression. RESULTS Within Cohort I, no statistically significant difference in disease-free survival (DFS) (P = 0.84) or overall survival (OS) (5-year survival 67% vs. 62%; P = 0.40) was observed between BCG treatment and observation. Within Cohort II, the addition of dacarbazine to BCG did not improve DFS (P = 0.74) or OS (P = 0.81) compared with BCG alone. Toxicity was mild to moderate in both cohorts. Although toxicity with this agent is mild, the use of BCG is associated with the development of punctate abscesses in greater than two-thirds of patients treated. CONCLUSIONS In what to our knowledge is the largest ever trial to test the role of BCG as adjuvant therapy for melanoma, no benefit for BCG was observed for patients with AJCC Stage I-III disease. The mature results of the current trial projected to 30 years confirmed the negative results of previous smaller studies utilizing this agent.

Abstract
Melanoma is a neoplasm with an incidence in the US that is rising at a rate second only to lung cancer in women. Early stage melanoma is curable, but advanced metastatic melanoma is almost uniformly fatal, even in 2003. The close relationship of melanoma with the immune system has led to a recent resurgence in the investigation of immunotherapy in the treatment of this disease. The two most widely investigated immunotherapy drugs for melanoma are interferon (IFN)-alpha and interleukin-2 (IL-2). The role of IFNalpha-2b in the adjuvant therapy of patients with localized melanoma at high risk for relapse has recently been established by the results of three large randomized trials conducted by the US Intergroup; all three trials demonstrated an improvement in relapse-free survival and two in overall survival. Recombinant IL-2 (rIL-2) has an overall response rate of 15-20% in metastatic melanoma and is capable of producing complete and durable remissions in about 6% of patients treated. Based upon these data, the US FDA has recently approved the use of high-dose bolus administration of rIL-2 for the therapy of patients with metastatic melanoma. Results of combination chemotherapy and immunotherapy regimens containing rIL-2 and IFNalpha (biochemotherapy) are promising, but conclusions regarding an advantage for this therapy in terms of survival must await the completion of ongoing randomized trials. The use of therapeutic vaccines is an ongoing area of research, and clinical trials of several types of vaccines (whole cell, carbohydrate, peptide) are being conducted in patients with intermediate and late-stage melanoma. In the setting of adjuvant therapy, to date, no vaccine has demonstrated a survival benefit in comparison with either observation or IFNalpha. Vaccines are also being tested in patients with metastatic melanoma to determine their immune effects and to define their activity in combination with other immunotherapeutic agents such as IL-2 or IFNalpha.

Abstract
Patients with thick, primary melanoma and regional lymph-node metastases are at moderate to high risk of recurrence and death, despite apparent complete surgical removal. Immune responses can be demonstrated against melanoma and this has prompted the conduct of a number of randomized trials of immunotherapy. Several trials have been completed and show minimal benefit in prolonging survival or recurrence from melanoma. Similarly, a large number of trials has been conducted to test the efficacy of alpha-2-interferon (IFN-alpha2) in therapy. Clear benefit in recurrence-free survival was shown in several trials, however there is a lack of convincing evidence of an effect on overall survival. Several trials of vaccine and IFN-alpha2 therapy are still in progress and their results are awaited with great interest. The use of high-dose IFN-alpha2 therapy remains a contentious subject, however available evidence suggests the standard of care remains good surgical management.

Abstract
OBJECTIVE To determine whether adjuvant postoperative active specific immunotherapy with a therapeutic polyvalent vaccine (PV) called Canvaxin can prolong survival following complete resection of melanoma metastatic to regional nodes (American Joint Committee on Cancer [AJCC] stage III melanoma). SUMMARY BACKGROUND DATA Despite complete lymphadenectomy, 5-year overall survival (OS) for patients with melanoma metastatic to regional lymph nodes is only 20% to 50%, depending on the number of tumor-involved nodes. In 1984, the authors began phase II trials of Canvaxin PV as postsurgical adjuvant therapy for AJCC stage III melanoma. METHODS Patients who received PV between 1984 and 1998 were compared with patients who did not receive PV postsurgical therapy between 1971 and 1998. The seven covariates recently defined by the AJCC Melanoma Staging Committee (number of metastatic nodes, palpable status, ulceration, age, primary site, pT stage, and gender) were included by Cox regression in a multivariate model of OS. A computerized program matched PV and non-PV patients by these covariates. RESULTS Of 2,602 patients who underwent complete lymphadenectomy for AJCC stage III melanoma with regional nodal metastases and were followed up by the same team of oncologists between 1971 and 1998, 935 received PV and 1,667 did not. Median OS and 5-year OS were significantly higher in PV than non-PV patients (56.4 vs. 31.9 months and 49% vs. 37%, respectively; P =.0001). When the non-PV patients were matched by the four most significant covariates, 447 matched pairs were formed between patients seen before or after January 1, 1985, and the OS was not different between the two time periods ( P=.789). However, when the PV patients were matched with non-PV patients by six covariates forming 739 pairs, the PV patients survived longer ( P=.0001). Detailed analysis of the 1,505 patients who were seen or who began vaccine therapy within 4 months after lymphadenectomy, and who had more complete data on the seven prognostic covariates showed that median OS and 5-year OS were higher in 445 PV patients than in 1,060 non-PV patients: 70.4 versus 31 months and 52% versus 37%, respectively (P =.0001). Multivariate Cox regression analysis identified six significant prognostic factors: number of metastatic nodes, size of metastatic nodes, pT stage, ulceration, age, and PV therapy. PV therapy reduced the relative risk of death to 0.64 (95% confidence interval, 0.55-0.76) ( P=.0001); sex and site of primary were of borderline significance. CONCLUSIONS This large single-institution study independently confirmed the significance of prognostic covariates in the new AJCC staging system. By using modern statistical methods that controlled for all known prognostic factors, it also demonstrated PV's ability to significantly enhance OS. A multicenter phase III randomized trial is underway to validate the efficacy of PV as a postsurgical adjuvant.

Abstract
High risk surgically resected melanoma is associated with a less than 50% 5-year survival. Adjuvant therapy is an appropriate treatment modality in this setting, and is more likely to be effective as the tumour burden here is small. Clinical observations of spontaneous tumour regressions and a highly variable rate of disease progression suggest a role of the immune system in the natural history of melanoma. Biological agents have therefore been the subjects of numerous adjuvant studies. Early, randomised controlled trials (RCTs) of Bacillus Calmette-Guerin (BCG), levamisole, Corynebacterium parvum, chemotherapy, isolated limb perfusion (ILP), radiotherapy, transfer factor (TF), megestrol acetate and vitamin A yielded largely negative results. Current trials focus on vaccines and the interferons. To date the latter is the only therapy to have shown a significant benefit in the prospective randomised controlled phase III setting. This report represents a systematic review of studies in adjuvant therapy in melanoma. Data from ongoing studies is awaited before a role for adjuvant agents in high risk melanoma is confirmed.

Abstract
PURPOSE No standard systemic adjuvant therapy has been proven to increase overall survival in melanoma patients. The effect of interferon alfa (IFNalpha) as a single agent or in combination has been widely explored in clinical trials. The purpose of this study was to assess the benefit of IFNalpha therapy in malignant melanoma. METHODS We performed a systematic review of randomized controlled trials comparing regimens with or without IFNalpha adjuvant therapy in melanoma patients. We assessed the effect of IFNalpha therapy on overall survival (OS), disease-free survival (DFS), melanoma recurrences, and toxicity. The quality of each trial was systematically evaluated. RESULTS Nine randomized controlled trials (RCTs) of IFNalpha therapy in melanoma patients were identified. Eight were published and one was unpublished. Eight trials comprising 3,178 patients fulfilled our inclusion criteria and were analyzed. Quality assessment scores ranged from 22 to 71, with a mean score of 55.4 (95% confidence interval, 53.8 to 57.0). For OS, only one trial reported a statistically significant benefit for IFNalpha, but our analysis did not confirm it. Two trials reported statistically significant benefit in DFS for the patients treated with IFNalpha, but our analysis confirmed it in only one trial. There was a wide clinical heterogeneity between included trials, making meta-analysis inappropriate. CONCLUSION In our review, results from included RCTs demonstrated no clear benefit of IFNalpha therapy on OS in melanoma patients. A large RCT is required to answer whether a full regimen of IFNalpha therapy is effective and to identify the subgroups of patients who might benefit from IFNalpha treatment.

Abstract
INTRODUCTION TA90 is a tumor-associated 90-kD glycoprotein antigen expressed on most melanoma cells, including those of CancerVax, a polyvalent allogeneic whole-cell vaccine. Previous studies have shown that a TA90 antigen-antibody immune complex (IC) in the serum of patients with melanoma is a marker of subclinical tumor burden and a strong prognostic factor. We hypothesized that the induction of TA90-IC during postoperative adjuvant CancerVax therapy might indicate vaccine-mediated immune destruction of subclinical melanoma cells with release of TA90, and thereby serve as a surrogate marker of vaccine efficacy. METHODS From 1993 to 1997, 219 melanoma patients were enrolled in a prospective phase II trial of CancerVax plus bacille Calmette-Guerin (BCG) after complete tumor resection. Coded serum samples were prospectively collected and analyzed for TA90-IC before and 2, 4, 8, 12, and 16 weeks after initiation of CancerVax therapy. TA90-IC seroconverters were those patients whose negative TA90-IC values (< .410) became positive (> or = .410) after initiation of CancerVax treatment. RESULTS Before CancerVax therapy, 51 patients had positive TA90-IC values and 168 patients had negative TA90-IC values. During CancerVax treatment, all 51 positive patients remained positive, 79 (47%) negative patients seroconverted to positive, and 89 (53%) negative patients remained negative. Seroconverters had higher 2-year rates of disease-free survival (59% vs. 32%; P < .006) and overall survival (78% vs. 63%; P < .02) than did patients whose TA90-IC values remained positive. CONCLUSIONS CancerVax induces TA90-IC in melanoma patients with subclinical disease. TA90-IC seroconverted patients have significantly improved disease-free and overall survival compared with TA90-IC positive patients. TA90-IC is an important prognostic factor that can serve as a surrogate marker for the clinical efficacy of CancerVax.

Abstract
Malignant melanoma displays strong resistance against various antineoplastic drugs. The mechanisms conferring this intrinsic resistance are unclear. To better understand the molecular events associated with drug resistance in melanoma, a panel of human melanoma cell variants exhibiting low and high levels of resistance to 4 commonly used drugs in melanoma treatment, i.e., vindesine, etoposide, fotemustine and cisplatin, was characterized by differential display reverse transcription-polymerase chain reaction (DDRT-PCR). Of 269 mRNA fragments found to be altered in expression level by DDRT-PCR, a total of 11 cDNA clones was characterized after confirmation of a differential expression pattern by Northern blot analyses. These clones include 3 genes (DSM-1, DSM-3 and DSM-5) of known function, 4 previously sequenced genes (DSM-2, DSM-4, DSM-6 and DSM-7) of uncharacterized function and 4 novel genes (DSM-8-DSM-11) without match in GenBank. All of these genes exhibited altered mRNA expression in high level etoposide-resistant cells, whereby 7 genes (DSM-1-DSM-6 and DSM-8) were found to be decreased in the transcription rate in these etoposide-resistant cells. The mRNA synthesis of the remaining genes (DSM-7 and DSM-9-DSM11) was enhanced in high level etoposide-resistant melanoma cells. The expression of 5 (DSM-5 and DSM-7-DSM-10) of the cloned cDNA encoding mRNAs was modulated in various independently established drug-resistant melanoma cells, indicating to be associated with drug resistance. Further characterization of these genes may yield inside into the biology and development of drug resistance in malignant melanoma.

Abstract
Recently, betulinic acid was identified as a highly selective inhibitor of human melanoma growth and was reported to induce apoptosis in these cells. We have investigated the growth-inhibitory properties of this compound alone and in combination with ionizing radiation in a panel of established human melanoma cell lines as well as in normal human melanocytes. Betulinic acid strongly and consistently suppressed the growth and colony-forming ability of all human melanoma cell lines investigated. In combination with ionizing radiation the effect of betulinic acid on growth inhibition was additive in colony-forming assays. Betulinic acid also induced apoptosis in human melanoma cells as demonstrated by Annexin V binding and by the emergence of cells with apoptotic morphology. The growth-inhibitory action of betulinic acid was more pronounced in human melanoma cell lines than in normal human melanocytes. Notably, despite the induction of apoptosis, analysis of the expression of Bcl-2 family members in betulinic-acid-treated cells revealed that expression of the anti-apoptotic protein Mcl-1 was induced. Furthermore, the antiproliferative action of betulinic acid seemed to be independent of the p53 status. The properties of betulinic acid make it an interesting candidate, not only as a single agent but also in combination with radiotherapy. We conclude that the strictly additive mode of growth inhibition in combination with irradiation suggests that the two treatment modalities may function by inducing different cell death pathways or by affecting different target cell populations.

Abstract
Interferons (IFN) are a group of related glycoproteins. IFN-gamma, in vitro, has been shown to inhibit resorption; however, an in vivo experiment showed that it had the opposite effect, resulting in bone loss that was comparable to that caused by cyclosporine A. IFN-alpha has numerous clinical applications but is used most extensively in the treatment of chronic hepatitis B and chronic hepatitis C. Research into the effects of IFN-alpha on bone mineral metabolism has been very sparse, and the majority of studies reflect in vitro models. Like IFN-gamma, there exists discordance between in vitro and in vivo studies on IFN-alpha. Both in vivo and in vitro studies demonstrate that IFN-alpha decreases bone resorption, whereas osteoblasts may or may not be affected in vivo. This study was designed to provide information on the in vivo effects of IFN-alpha in the rat model, because we feel that, given its widespread clinical use, this is an extremely important issue. Rats were given low dose IFN-alpha (1.6 x 10(6) IU/m2), intermediate dose IFN-alpha (5.35 x 10(6) IU/m2), and high dose IFN-alpha (30 x 10(6) IU/m2) three times per week for 28 days. Serum osteocalcin (bone gla protein, or BGP) and parathyroid hormone (PTH) were measured serially and, after double labeling, the bones were examined histomorphometrically. IFN-alpha did not alter any of the histomorphometric parameters measured and did not affect PTH. However, it produced a disparate BGP response. Low dose IFN-alpha resulted in a statistically significant increase in serum BGP on days 14 and 28, whereas intermediate and high doses of IFN-alpha did not. Overall, these results provide no evidence of a deleterious effect of IFN-alpha on bone metabolism and confirm the limited clinical study.

Abstract
PURPOSE Radiotherapy is used as a "last resort" for patients with advanced cutaneous malignant melanoma. We have analyzed our 20-year clinical experience with respect to different endpoints and prognostic factors in patients with locally advanced, recurrent, or metastatic malignant melanoma. METHODS From 1977 to 1995, 2,917 consecutive patients were entered in the melanoma registry of our hospital. Radiotherapy was indicated in 121 patients (56 females, 65 males) for palliative reasons in advanced malignant melanoma stages UICC IIB/III/IV. The histology of the primary lesion was nodular in 51 patients, superficial spreading in 35, acral-lentiginous in 8, and lentigo maligna melanoma in 4 patients. Eleven patients had primary or recurrent lesions which were either not eligible for surgery or had residual disease (R2) after resection of a primary or recurrent lesion (UICC IIB); 57 patients had lymph node (n = 33) or in-transit metastases (n = 24) (UICC III), and 53 had distant organ metastases (7 M1a; 46 M1b) (UICC IV). Time from first diagnosis to on-study radiotherapy averaged 19 (median: 18; range: 3-186) months. In most cases, conventional RT was applied with 2-6 Gy single fractions up to a median total radiation dose of 48 (mean: 45; range: 20-66) Gy. RESULTS At 3 months follow-up, complete response (CR) was achieved in 7 (64%) and overall response [complete (CR) and partial response (PR)] in all (100%) UICC IIB patients, in 25 (44%) and 44 (77%) of 57 UICC III patients, and in 9 (17%) and 26 (49%) of 53 UICC IV patients. Tumor progression during radiotherapy occurred in 25 (21%) patients. Patients with CR survived longer (median: 40 months) than those without CR (median 10 months) (p < 0.01). At last follow-up (Dec 31, 1996), 26 patients were still alive: 6 (55%) UICC IIB, 17 (30%) UICC III, and 3 (6%) UICC IV patients (p < 0.01). Univariate analysis revealed the following prognostic factors for complete response and long-term survival: UICC stage (p < 0.001), primary location in the head and neck region, total radiation dose above 40 Gy (all p < 0.05), while age, gender, and histology had no impact. In multivariate analysis, UICC stage was the only independent prognostic factor (p < 0.001). CONCLUSION External beam radiotherapy can provide long-term local control and effective palliation in malignant melanoma UICC stages IIB-IV. The current UICC staging system is an excellent prognostic factor for initial and long-term tumor response in metastatic melanoma. Therefore, prospective randomized trials using external radiotherapy with or without adjuvant therapy for advanced malignant melanoma are justified.

Abstract
Cutaneous melanoma represents the main cause of death among skin cancers. Early diagnosis gives, for the time being, the only possibility for high rate of curative treatment. Diagnosis is based on pathological findings, and at primary tumor stage. Breslow thickness of the lesion is the best prognostic index. At local stage of the disease, treatment is precisely codified by international recommendations and consensus conferences. Follow-up after surgical treatment is also well codified. Treatment of lymph node invasion or metastatic disease is, on the other hand, less codified. Despite recent advances, especially in immunotherapy, treatment of advanced stages of melanoma remains difficult.

Abstract
Several melanosome glycoproteins have been shown to be antigenic in humans. Correlation of antigen-specific immune responses in patients with the autoimmune disease vitiligo, therapy-induced hypopigmentation, and cutaneous melanoma has not been well studied. We examined antibody responses to a melanocyte autoantigen, tyrosinase-related protein-2 (TRP-2), as it is highly expressed in cutaneous melanoma and melanocytes. TRP-2 recombinant protein was synthesized for western blot and affinity anti-TRP-2 enzyme-linked immunosorbent assay. We demonstrated that patients with malignant melanoma, vitiligo, and active-specific immunotherapy-induced depigmentation had significant anti-TRP-2 IgG titers. The highest level of anti-TRP-2 IgG response was found in vitiligo patients. Induction and enhancement of anti-TRP-2 IgG responses were observed in melanoma patients treated with a polyvalent melanoma cell vaccine containing TRP-2. Active-specific immunotherapy could induce and/or augment the TRP-2 IgG antibody titers. Melanoma patients who developed hypopigmentation and had improved survival after polyvalent melanoma cell vaccine had significantly augmented anti-TRP-2 antibody responses compared with patients with poor prognosis. This study demonstrates that TRP-2 autoantigen is immunogenic in humans. TRP-2 antibody responses provide a linkage between autoimmune responses by vitiligo patients and melanoma patients responding to immunotherapy who have induced hypopigmentation.

Abstract
The penetration of the subepithelial basement membrane is the first critical step in the dissemination of melanoma. In vitro studies have suggested that the 72 kD type IV collagenase (MMP-2) may be important in melanoma invasion. It has recently been demonstrated that the expression of MMP-2 immunoreactive protein increased with increasing atypia in melanocytic tumours and was associated with later haematogenous metastases in melanoma. This paper investigates the value of MMP-2 as a possible prognostic marker in melanoma. The expression of MMP-2 immunoreactive protein was studied with immunoperoxidase staining in paraffin-embedded sections of 50 cases of primary skin melanoma by using specific, affinity purified antibodies. Positive immunostaining was quantified by counting the percentage of positive cancer cells and was compared with clinical patient characteristics and survival. Sixty-four per cent of the primary melanoma cases displayed positive cytoplasmic immunostaining for MMP-2 in tumour cells. Marked overexpression of MMP-2 protein (> or = 34 per cent of melanoma cells positive) correlated with the 5-year survival of the patients when compared with patients with lower MMP-2 positivity, 55 per cent vs. 85 per cent, respectively (P < 0.05). Male patients displayed positive staining more often than females (75 per cent vs. 54 per cent, respectively). There was no correlation between MMP-2 positivity and Clark level or Breslow classification. A distinct group with unfavourable prognosis was identified. The 10-year survival for MMP-2-positive male melanoma patients was 39 per cent as opposed to 79 per cent with the other melanoma patients (P < 0.05). In the hierarchic Cox regression model for survival, MMP-2 immunoreactive protein was found to be independent of Clark level and Breslow classification. Overexpression of MMP-2 protein indicated a 4.5-fold relative risk of dying from melanoma. It is concluded that MMP-2 immunoreactive protein in melanoma cells is an independent prognostic factor for survival. High MMP-2 expression in male melanoma patients indicates an unfavourable prognosis.

Abstract
BACKGROUND Owing to the limited efficacy of therapy on melanoma at the stage of distant metastases, a well-tolerated adjuvant therapy is needed for patients with high-risk primary melanoma. Our hypothesis was that an adjuvant treatment with low doses of interferon alpha could be effective in patients with localised melanoma. METHODS After resection of a primary cutaneous melanoma thicker than 1.5 mm, patients without clinically detectable node metastases were randomly assigned to receive either 3x10(6) IU interferon alpha-2a, three-times weekly for 18 months, or no treatment. The primary endpoint was the relapse-free interval. FINDINGS 499 patients were enrolled, of whom 489 were eligible. When used as part of a sequential procedure, interferon alpha-2a was of significant benefit for relapse-free interval (p=0.038). A long-term analysis, after a median follow-up of 5 years, showed a significant extension of relapse-free interval (p=0.035) and a clear trend towards an increase in overall survival (p=0.059) in interferon alpha-2a-treated patients compared with controls. There were 100 relapses and 59 deaths among the 244 interferon alpha-2a-treated patients compared with 119 relapses and 76 deaths among the 245 controls. The estimated 3-year-relapse rates were 32% in the interferon alpha-2a group and 44% in controls; the 3-year death rates were 15% and 21%, respectively. Only 10% of patients experienced WHO grade 3 or 4 adverse events. Treatment was compatible with normal daily life. INTERPRETATION Adjuvant therapy of high-risk melanoma with low doses of interferon alpha-2a for 18 months is safe and is beneficial when started before clinically detectable node metastases develop.

Abstract
Cellular and cytokine adjuvants, often immune effector cells and soluble factors, respectively, are supplemental and/or follow-up treatments of human origin for cancer patients who have unsatisfactory clinical responses to conventional chemotherapy, radiotherapy, and surgery. Since many human studies with these reagents are in their infancy, extensive data collection is only now being performed to determine which strategy provides the greatest therapeutic benefit. Research published in the literature since the genesis of this approach to cancer treatment is summarized in this report. Methodologies attempting to generate anticancer responses by provoking or enhancing the patient's own immune system are new compared with the other standard types of cancer treatment. Although a few encouraging human studies can be discussed, many of the most promising techniques are only now being transferred from the laboratory to the clinic. The administration of immune effector cells in combination with immunomodulators, such as interferons or interleukins, often enhances clinical outcome. The literature cited in this report indicate that immune-cell- and cytokine-based therapies hold promise in our attempts to improve the quality and duration of life in those with cancer. With each report reaching the literature, more effective clinical trials are being designed and implemented.

Abstract
BACKGROUND Early surgical intervention is still the most successful therapy for patients with melanoma. The results obtained with medical therapies are still quite disappointing, with better results observed in soft tissue and lymph node metastasis. There currently is no standardized adjuvant therapy for primary melanoma. On the basis of the activity demonstrated in vitro against melanoma cell lines and the results obtained in many clinical trials in patients with advanced melanoma, the authors chose to study the use of recombinant interferon-alpha (IFN-alpha) as adjuvant therapy for patients with Stage I and Stage II melanoma. METHODS A randomized multicenter trial based on the use of recombinant IFN-alpha-2b for 3 years at the dose of 3 MU given intramuscularly 3 times a week for a period of 6 months with a 1-month interval between cycles was conducted in Stage I and Stage II melanoma patients (using the American Joint Committee on Cancer classification). The efficacy of this treatment was evaluated calculating the incidence of recurrence after 3 and 5 years. RESULTS Results were collected at the end of the treatment period and after 5 years of follow-up for a smaller number of patients. Statistical evaluation showed a significant difference between treated patients and untreated controls with regard to progression of the disease. In particular, IFN-alpha appears to be more effective in patients with worse prognosis lesions. CONCLUSIONS IFN-alpha appears to be effective as adjuvant therapy for high risk melanoma patients and the risk/benefit ratio appears to be very favorable. The authors' next goal is to separate those patients who might benefit from adjuvant therapy from those who are cured after the surgical intervention only.

Abstract
Cancer vaccines are based on the concept that tumors express novel antigens and thus differ from their normal tissue counterparts. Such putative tumor-specific antigens should be recognizable by the immune system. However, malignant cells are of self origin and only poorly immunogenic, which limits their capability to induce an anticancer immune response. To overcome this problem, tumor cells have been isolated, genetically engineered to secrete cytokine gene products and administered as cancer vaccines. We used adenovirus-enhanced transferrinfection (AVET), which allows high-level transient transgene expression, to introduce cytokine gene expression vectors into murine melanoma cells. The efficiency of AVET makes laborious selection and cloning procedures obsolete. We administered such modified tumor cells as cancer vaccines to syngeneic animals and investigated their impact on the induction of anticancer immunity. We found that IL-2 or GM-CSF gene-transfected murine melanoma cells are highly effective vaccines. Both of these cytokine-secreting vaccines cured 80% of animals which bore a subcutaneous micrometastasis prior to treatment, and induced potent antitumor immunity. The generation of antitumor immunity by these cytokine-secreting vaccines requires three different steps: (1) tumor antigen uptake and processing by antigen-presenting cells (APCs) at the site of vaccination; (2) migration of these APCs into the regional lymph nodes where T-cell priming occurs; (3) recirculation of specific, activated T-cells that recognize distinct tumor load and initiate its elimination. Extending our previously reported studies, we have now comprehensively analysed the requirements for effective antitumor vaccination in animals. This may also become the basis for treatment of human cancer patients.

Abstract
BACKGROUND Synchronous neoplasms of the rectum are an uncommon condition. The situation becomes more rare when tumors are of different origin. To the authors' knowledge, synchronous anorectal melanoma and adenocarcinoma of the rectum have not been reported in the literature before. METHODS AND RESULTS A 67-year-old female patient with synchronous anorectal malignant melanoma and adenocarcinoma of the rectum is described. She had preoperative colonoscopic diagnosis. The different neoplasms' origin was histologically proven. Surgical management consisted of abdominoperineal resection of the rectum. Postoperatively, the patient received adjuvant chemotherapy of six cycles duration. At present, the patient has completed 32 months of follow-up. There is no evidence of recurrent disease or distant metastases. CONCLUSION Review of the literature confirms the rarity of anorectal malignant melanoma. On the other hand, the rectum represents the most common site for development of colonic adenocarcinoma. We were unable to trace synchronous presentation of these two tumors. Prognosis should be defined by the most malignant neoplasm; therefore, management should be focused on treating the melanoma.

Abstract
BACKGROUND Patients with metastatic melanoma to their regional lymph nodes have a poor prognosis despite lymphadenectomy. In an attempt to improve their survival, this feasibility study was undertaken. METHODS Twenty-two melanoma patients, who presented with enlarged regional lymph nodes, underwent therapeutic lymphadenectomy. They were found to have N2 nodal disease, with no evidence of distant metastases, i.e., advanced Stage III disease. One month after the lymphadenectomy, each patient received five autologous tumor vaccines. Each vaccine consisted of 20 x 10(6) irradiated autologous tumor cells (20,000 cGy) injected intradermally. The first two vaccines contained BCG and were given 1 week apart. The other three vaccines consisted of irradiated tumor cells only without BCG, administered over 2-, 4-, and 8- week intervals, respectively. Cyclophosphamide was administered intravenously as 300 mgm/m2 3 days prior to vaccines 1, 4, and 5 to reduce the population of T-suppressor cells. The patients were observed with no additional therapy. Three patients developed recurrences and these site were resected, and the patients were revaccinated in the same fashion utilizing the new tumor cells. RESULTS After a follow-up of 4-6 years, 15 patients (including 3 who were revaccinated) of the initial 22 patients (68.2%) are alive free of disease. CONCLUSIONS Adjuvant immunotherapy with irradiated autologous melanoma cells and low dose cyclophosphamide seemed to yield better relapse-free survival than the historically reported 10-25%.

BACKGROUND Melanoma patients who carry the human leukocyte antigen (HLA) Class II allele DQB1*0301 have an increased frequency of metastases at presentation compared with those lacking HLA-DQB1*0301. This study was designed to determine whether HLA-DQB1*0301 is associated with an increased risk of recurrence in melanoma patients presenting with American Joint Committee on Cancer (AJCC) Stage I or II (localized) disease. METHODS Molecular oligotyping of HLA-DQ genes was performed for 259 patients with AJCC Stage I or II melanoma. Rate of disease recurrence was determined by retrospective review and prospective follow-up. Kaplan-Meier analysis, log rank, and proportional hazard (Cox) comparison were performed. RESULTS Median follow-up was 24 months. Minimum follow-up was 6 months. Although HLA-DQB1*0301-positive and -negative patients were balanced with regard to standard melanoma prognostic factors (primary tumor thickness, level of invasion, presence of ulceration, anatomic location, and sex), HLA-DQB1*0301-positive patients were more likely to develop locally recurrent, regional, or distant metastatic melanoma during follow-up (actuarial median disease free survival 48 months [DQB1*0301-positive patients] vs. 97 months [DQB1*0301-negative patients]; log rank P = 0.0002). HLA-DQB1*0301 status, in addition to primary tumor thickness, was an independent prognostic indicator in these patients (Cox multivariate P = 0.02). CONCLUSIONS Patients presenting with localized melanoma who carry HLA-DQB1*0301 are at an increased risk of developing recurrent disease compared with stage-matched patients who lack this allele. HLA-DQB1*0301 is a genomic marker which independently identifies melanoma patients in whom recurrence is more likely, and is potentially useful in selecting those most likely to benefit from adjuvant therapy.
