Abstract
Checkpoint inhibitors are introduced as a therapy for clinical use for various cancers, and clinicians are documenting new adverse effects. This is the first case report to the best of our knowledge of a patient on checkpoint inhibitor presenting with both polyendocrinopathy and gangrenous gallbladder disease with a mass negative for malignancy.71-year-old man presented four years after his initial diagnosis of stage IV, unresectable, non-ulcerated, acryl, lentiginous malignant melanoma. On presentation, he had gangrenous cholecystitis and was treated with laparoscopic cholecystectomy. Incidentally, the patient was diagnosed two years ago with hypothyroidism, hypophysitis, secondary adrenal insufficiency, and pneumonitis, each suspected to be secondary to treatment with pembrolizumab (Keytruda), a monoclonal anti-programmed cell death-1 antibody. He presented to the emergency department for a gallbladder attack and underwent successful laparoscopic cholecystectomy. The intra-operative finding on opening the specimen was an unusual looking exophytic mass but was negative for malignancy on pathology report and reported as gangrenous cholecystitis. His clinical condition before and after surgery was complicated by worsening comorbidities thought to be secondary to pembrolizumab therapy, which required acute care hospitalizations in the weeks before and after his presentation with cholecystitis. The patient had a few admissions from other co-morbidities post-surgery and was doing better. Immunotherapy with pembrolizumab may have secondary and tertiary effects with unusual presentations that are difficult to interpret for the primary oncology team and even tougher to do for community physicians who may subsequently encounter these patients. The relationship of this patient's comorbidities with immune-related adverse events was not apparent until record requests were conducted after surgery and are still not entirely clear after a literature review. More data is needed to guide decision algorithms and to predict which patients may experience these effects.

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
In melanoma patients, one of the main reasons for tumor immune escape and therapy failure is the immunosuppressive tumor microenvironment. Herein, suppressive immune cells and inhibitory factors secreted by the tumor itself play a central role. In the present study we show that the Treg activation marker GARP (glycoprotein A repetitions predominant), known to induce peripheral tolerance in a TGF-β dependent way, is also expressed on human primary melanoma. Interestingly, membrane bound GARP is shed from the surface of both, activated Treg and melanoma cells, and, in its soluble form (sGARP), not only induces peripheral Treg but also a tumor associated (M2) macrophage phenotype. Notably, proliferation of cytotoxic T cells and their effector function is inhibited in the presence of sGARP. GARP expression on Treg and melanoma cells is significantly decreased in the presence of agents such as IFN-α, thus explaining at least in part a novel mechanism of action of this adjuvant therapy. In conclusion, GARP in its soluble and membrane bound form contributes to peripheral tolerance in a multipronged way, potentiates the immunosuppressive tumor microenvironment and thus acts as a negative regulator in melanoma patients. Therefore, it may qualify as a promising target and a new checkpoint for cancer immunotherapy.

Abstract
Dacarbazine (DTIC) is a cytotoxic drug widely used for melanoma treatment. However, the putative contribution of anticancer immune responses in the efficacy of DTIC has not been evaluated. By testing how DTIC affects host immune responses to cancer in a mouse model of melanoma, we unexpectedly found that both natural killer (NK) and CD8(+) T cells were indispensable for DTIC therapeutic effect. Although DTIC did not directly affect immune cells, it triggered the upregulation of NKG2D ligands on tumor cells, leading to NK cell activation and IFNγ secretion in mice and humans. NK cell-derived IFNγ subsequently favored upregulation of major histocompatibility complex class I molecules on tumor cells, rendering them sensitive to cytotoxic CD8(+) T cells. Accordingly, DTIC markedly enhanced cytotoxic T lymphocyte antigen 4 inhibition efficacy in vivo in an NK-dependent manner. These results underscore the immunogenic properties of DTIC and provide a rationale to combine DTIC with immunotherapeutic agents that relieve immunosuppression in vivo.

Abstract
In the current study, we examined the potential significance of CD44 expression on lymphokine-activated killer (LAK) cells in their interaction and killing of melanoma cells. Stimulation of splenocytes with IL-2 led to a significant increase in the expression of CD44 on T cells, NK cells, and NKT cells. Treatment of melanoma-bearing CD44 WT mice with IL-2 led to a significant reduction in the local tumor growth while treatment of melanoma-bearing CD44 KO mice with IL-2 was ineffective at controlling tumor growth. Furthermore, the ability of splenocytes from IL-2-treated CD44 KO mice to kill melanoma tumor targets was significantly reduced when compared to the anti-tumor activity of splenocytes from IL-2-treated CD44 WT mice. The importance of CD44 expression on the LAK cells was further confirmed by the observation that adoptively transferred CD44 WT LAK cells were significantly more effective than CD44 KO LAK cells at controlling tumor growth in vivo. Next, the significance of the increased expression of CD44 in tumor killing was examined and showed that following stimulation with IL-2, distinct populations of cells with low (CD44(lo)) or elevated (CD44(hi)) expression of CD44 are generated and that the CD44(hi) cells are responsible for killing of the melanoma cells. The reduced killing activity of the CD44 KO LAK cells did not result from reduced activation or expression of effector molecules but was due, at least in part, to a reduced ability to adhere to B16F10 tumor cells.

Abstract
BACKGROUND Immunotherapy for cutaneous malignancy involves manipulating the immune system to treat and prevent skin cancer. Although initial efforts were fraught with low success rates and technical challenges, more-recent endeavors have yielded response rates approaching 50% for treating metastatic melanoma. Many of these advances are a result of increasing knowledge of the immune system's intricacies and continued progress in laboratory techniques. OBJECTIVE To review our current understanding of the skin immune system and discuss how these factors contribute to the host response to malignancy and to report the current state of immunotherapeutic techniques. MATERIALS AND METHODS An extensive PubMed literature search was conducted in topics involving immunotherapy with specific relevance to cutaneous malignancy using the MeSH terms "immunotherapy" and "skin cancer." RESULTS Despite initially poor patient responses to these treatment modalities, recent gains in scientific knowledge and clinical intervention protocols have brought immunotherapy to the forefront of prospective skin cancer therapeutics, particularly for advanced melanoma. CONCLUSIONS Current treatment options for advanced cutaneous malignancies such as melanoma are low in efficacy. Immunotherapies have the potential to provide novel approaches to address this, particularly when used in combination. The authors have indicated no significant interest with commercial supporters.

Abstract
A 22-year-old man was admitted with complaints of dyspnea and hoarseness. Laryngoscopy and computed tomography of the neck revealed a 1.5 x 2-cm solid mass obstructing the trachea. The black, pedunculated mass was completely removed through a tracheal incision, and a paratracheal lymph node dissection was performed. Histopathologic examination revealed nodular-type mucosal malignant melanoma. Cranial and thoracic computed tomography, abdominal ultrasonography, and histopathologic examination of the paratracheal lymph nodes showed no metastases. No recurrence has been noted in more than 3 years of follow-up.

Abstract
Malignant melanoma is a potentially fatal skin cancer that is increasing in incidence. Standard chemoimmunotherapy consisting of dacarbazine (DTIC) given with IFN-alpha has had disappointing results. We describe a chemoimmunotherapy protocol for cutaneous melanoma that combines the administration of DTIC with the topical application of CpG oligodinucleotide (ODN). Subcutaneous B16 melanoma tumors in C57BL/6 mice were treated with intraperitoneal injections of DTIC followed by the topical application of CpG-ODN over the tumors. This therapeutic approach abrogated the growth of established tumors and significantly enhanced survival. Topical CpG application was more effective than intratumoral CpG. Cell depletion studies indicated that the antitumor effect was dependent on both CD4(+) and CD8(+) cells but not on natural killer (NK) cells. Tumor-specific cytotoxic T-lymphocyte activity was generated in treated animals and was highest in topically treated animals. Immunohistochemical analysis revealed that DTIC, but not CpG, enhanced tumor cell apoptosis. Further, topical CpG induced an expansion of a B220(+)CD8(+) subset of dendritic cells and a subset of NK1.1(+) CD11c(+) cells within the tumors. By enhancing both tumor cell death and local immune activation, DTIC/topical CpG chemoimmunotherapy induced an effective T-cell-dependent host-immune response against melanoma.

Abstract
The sentinel lymph node (SLN) is thought to be an important lymphoid organ for protecting against metastasis and is thought to play a crucial part in provoking antitumour immunity. Because SLN biopsy is undertaken for various types of cancers, such as malignant melanoma and breast cancer, SLN mapping has become a standard procedure, thereby eliminating unnecessary lymph-node resection in patients who do not have affected nodes. The immune surveillance activities of the SLN in melanoma and breast cancer are thought to be suppressed, whereas in cancers of gastrointestinal-tract, the presence of T cells in the SLN has not been shown to suppress the host's immune function. Furthermore, cell death after primary systemic chemotherapy for solid tumours can provoke an antigen-specific immunity in the tumour, which affects tumour response to treatment and, therefore, survival in patients. This review discusses the immunobiology of the SLN and potential strategies for activation of antitumour immunity by primary systemic chemotherapy and other modalities, in terms of tumour-size reduction and survival benefit.

Abstract
Melanoma continues to be one of the most difficult to treat of all solid tumors. Many new advances have been made in the surgical management of melanoma, including new guidelines for margins of excision, as well as sentinel node biopsy for the diagnosis of lymph node micrometastases. The search continues for an effective adjuvant melanoma treatment that can prevent local and distant recurrences. Melanoma is one of the most immunogenic of all tumors, and several clinical trials testing the immunotherapy of melanoma have been conducted, including trials in interferon, interleukin-2, and melanoma vaccines. Here we discuss many of the recent clinical trials in the surgical management of melanoma, in addition to the advances that have been made in the field of immunotherapy. A new second-generation melanoma vaccine, DC-MelVac (patent # 11221/5), has recently been granted FDA approval for Phase I clinical trials and will be introduced in this review.

Abstract
The research area of tumor microenvironment is considered, at present, to be an important factor in tumorigenesis and especially in tumor progression. The present mini review is focused on three principles characterizing the nature of the tumor microenvironment. We first discuss the regulatory functions of the tumor microenvironment and the complexity of the combinatorial signaling pathways operating in it. We then address the aspect that the tumor microenvironment incorporates both pro and anti malignancy factors and that a balance between these factors regulates tumor progression. Thirdly we provide evidence that the non-tumor cells in the tumor microenvironment and their products may be different from those of their counterparts residing in non-tumor microenvironments. The conclusion of this mini review is that the tumor microenvironment, by exerting regulatory functions and selective pressures drives cancer cells into one of several molecular evolution pathways thereby determining and shaping their malignancy phenotype.

Abstract
This review shall present an update in anticancer ganglioside-based immunotherapies, with particular emphasis on molecular vaccines and anti-idiotype mAbs produced by the Center of Molecular Immunology (Havana, Cuba). The project comprises vaccines of N-acetyl or N-glycolylneuraminic acid GM3 ganglioside incorporated into very small proteoliposomes and anti-idiotype antibodies to glycolylated gangliosides. Development of these vaccine preparations from preclinical models of melanoma, breast and lung cancer to human investigation is summarized. A brief discussion on the progress and limitations of present-day clinical trials and future prospects is also included.

Abstract
The T-cell receptor (TCR) functions in both antigen recognition and signal transduction, which are crucial initial steps of antigen-specific immune responses. TCR integrity is vital for the induction of optimal and efficient immune responses, including the routine elimination of invading pathogens and the elimination of modified cells and molecules. Of the TCR subunits, the zeta-chain has a key role in receptor assembly, expression and signalling. Downregulation of TCR zeta-chain expression and impairment of T-cell function have been shown for T cells isolated from hosts with various chronic pathologies, including cancer, and autoimmune and infectious diseases. This review summarizes studies of the various pathologies that show this phenomenon and provides new insights into the mechanism responsible for downregulation of zeta-chain expression, its relevance and its clinical implications.

Abstract
As yet there are no FDA-approved cancer vaccines for malignant melanoma, but encouraging response rates and low toxicities reported in phase I/II trials suggest that antigen-based active immunotherapy may complement current treatment modalities. The cumulative data for Canvaxin therapeutic polyvalent cancer vaccine represent the largest phase II clinical trial of any cancer vaccine. Univariate and multivariate analyses of these data have demonstrated the prognostic significance of this allogeneic whole-cell preparation as a postoperative adjuvant treatment for patients with stage III and IV melanoma. The vaccine has also been shown promising results after resection of stage II melanoma and in patients with regional in-transit disease. The consistent correlation between immune and clinical responses to the vaccine suggests that immune parameters may be used to monitor a patient's response to vaccine therapy.

Abstract
Dendritic cell (DC) immunotherapy has shown significant promise in animal studies as a potential treatment for cancer. Its application in the clinic depends on the results of human trials. Here, we review the published clinical trials of cancer immunotherapy using exogenously antigen-exposed DCs. We begin with a short review of general properties and considerations in the design of such vaccines. We then review trials by disease type. Despite great efforts on the part of individual investigative groups, most trials to date have not yielded data from which firm conclusions can be drawn. The reasons for this include nonstandard DC preparation and vaccination protocols, use of different antigen preparations, variable means of immune assessment, and nonrigorous criteria for defining clinical response. While extensive animal studies have been conducted using DCs, optimal parameters in humans remain to be established. Unanswered questions include optimal cell dose, use of mature versus immature DCs for vaccination, optimal antigen preparation, optimal route, and optimal means of assessing immune response. It is critical that these questions be answered, as DC therapy is labor- and resource-intensive. Cooperation is needed on the part of the many investigators in the field to address these issues. If such cooperation is not forthcoming, the critical studies that will be required to make DC therapy a clinically and commercially viable enterprise will not take place, and this therapy, so promising in preclinical studies, will not be able to compete with the many other new approaches to cancer therapy presently in development. Trials published in print through June 2003 are included. We exclude single case reports, except where relevant, and trials with so many variables as to prevent interpretation about DC therapy effects.

Abstract
Emphasis for the treatment of melanoma should be shifted more to prevention and early diagnosis, because early melanoma may potentially be cured in most cases. Clinical trials are important to establish more effective adjuvant modalities against melanoma. Multifaceted aspects of micrometastasis, including differentiation of different clones with respect to the primary tumor, acquisition of adhesion molecules, and host interaction with the microscopic tumor, will shed new light on the biology and mechanism of early metastasis. New molecular and genetic tools may be used to dissect the mechanisms of lymphatic and hematogenous routes of metastasis. If such mechanisms can be understood, potential therapeutic maneuvers can be developed to prevent the process of micrometastasis.
