1 Guideline The Society for Immunotherapy of Cancer consensus statement on tumour immunotherapy for the treatment of cutaneous melanoma. 2013

Kaufman, Howard L / Kirkwood, John M / Hodi, F Stephen / Agarwala, Sanjiv / Amatruda, Thomas / Bines, Steven D / Clark, Joseph I / Curti, Brendan / Ernstoff, Marc S / Gajewski, Thomas / Gonzalez, Rene / Hyde, Laura Jane / Lawson, David / Lotze, Michael / Lutzky, Jose / Margolin, Kim / McDermott, David F / Morton, Donald / Pavlick, Anna / Richards, Jon M / Sharfman, William / Sondak, Vernon K / Sosman, Jeffrey / Steel, Susan / Tarhini, Ahmad / Thompson, John A / Titze, Jill / Urba, Walter / White, Richard / Atkins, Michael B. ·Rush University Cancer Center, 1725 West Harrison Street, Chicago, IL 60612, USA. ·Nat Rev Clin Oncol · Pubmed #23982524.

ABSTRACT: Immunotherapy is associated with durable clinical benefit in patients with melanoma. The goal of this article is to provide evidence-based consensus recommendations for the use of immunotherapy in the clinical management of patients with high-risk and advanced-stage melanoma in the USA. To achieve this goal, the Society for Immunotherapy of Cancer sponsored a panel of melanoma experts--including physicians, nurses, and patient advocates--to develop a consensus for the clinical application of tumour immunotherapy for patients with melanoma. The Institute of Medicine clinical practice guidelines were used as a basis for this consensus development. A systematic literature search was performed for high-impact studies in English between 1992 and 2012 and was supplemented as appropriate by the panel. This consensus report focuses on issues related to patient selection, toxicity management, clinical end points and sequencing or combination of therapy. The literature review and consensus panel voting and discussion were used to generate recommendations for the use of immunotherapy in patients with melanoma, and to assess and rate the strength of the supporting evidence. From the peer-reviewed literature the consensus panel identified a role for interferon-α2b, pegylated-interferon-α2b, interleukin-2 (IL-2) and ipilimumab in the clinical management of melanoma. Expert recommendations for how to incorporate these agents into the therapeutic approach to melanoma are provided in this consensus statement. Tumour immunotherapy is a useful therapeutic strategy in the management of patients with melanoma and evidence-based consensus recommendations for clinical integration are provided and will be updated as warranted.

2 Review Targeting damage-associated molecular pattern molecules (DAMPs) and DAMP receptors in melanoma. 2014

Boone, Brian A / Lotze, Michael T. ·Department of Surgery, Hillman Cancer Center, University of Pittsburgh Cancer Institute, Pittsburgh, PA, USA. ·Methods Mol Biol · Pubmed #24258998.

ABSTRACT: Damage-associated molecular pattern molecules (DAMPs) are proteins released from cells under stress due to nutrient deprivation, hypoxia, trauma, or treatment with chemotherapy, among a variety of other causes. When released, DAMPs activate innate immunity, providing a pathway to a systemic inflammatory response in the absence of infection. By regulating inflammation in the tumor microenvironment, promoting angiogenesis, and increasing autophagy with evasion of apoptosis, DAMPs facilitate cancer growth. DAMPs and DAMP receptors have a key role in melanoma pathogenesis. Due to their crucial role in the development of melanoma and chemoresistance, DAMPs represent intriguing targets at a time when novel treatments are desperately needed.

ABSTRACT: Adoptive cell therapy (ACT) using autologous tumor-infiltrating lymphocytes (TIL) has been tested in advanced melanoma patients at various centers. We conducted a systematic review and meta-analysis to assess its efficacy on previously treated advanced metastatic cutaneous melanoma. The PubMed electronic database was searched from inception to 17 December 2018 to identify studies administering TIL-ACT and recombinant interleukin-2 (IL-2) following non-myeloablative chemotherapy in previously treated metastatic melanoma patients. Objective response rate (ORR) was the primary end point. Secondary end points were complete response rate (CRR), overall survival (OS), duration of response (DOR) and toxicity. Pooled estimates were derived from fixed or random effect models, depending on the amount of heterogeneity detected. Analysis was carried out separately for high dose (HD) and low dose (LD) IL-2. Sensitivity analyses were carried out. Among 1211 records screened, 13 studies (published 1988 - 2016) were eligible for meta-analysis. Among 410 heavily pretreated patients (some with brain metastasis), 332 received HD-IL-2 and 78 LD-IL-2. The pooled overall ORR estimate was 41% [95% confidence interval (CI) 35% to 48%], and the overall CRR was 12% (95% CI 7% to 16%). For the HD-IL-2 group, the ORR was 43% (95% CI 36% to 50%), while for the LD-IL-2 it was 35% (95% CI 25% to 45%). Corresponding pooled estimates for CRR were 14% (95% CI 7% to 20%) and 7% (95% CI 1% to 12%). The majority of HD-IL-2 complete responders (27/28) remained in remission during the extent of follow-up after CR (median 40 months). Sensitivity analyses yielded similar results. Higher number of infused cells was associated with a favorable response. The ORR for HD-IL-2 compared favorably with the nivolumab/ipilimumab combination following anti-PD-1 failure. TIL-ACT therapy, especially when combined with HD-IL-2, achieves durable clinical benefit and warrants further investigation. We discuss the current position of TIL-ACT in the therapy of advanced melanoma, particularly in the era of immune checkpoint blockade therapy, and review future opportunities for improvement of this approach.

4 Article The power of negative thinking: which cells limit tumor immunity? 2012

Tang, Siuwah / Lotze, Michael T. ·Department of Surgery, University of Pittsburgh Cancer Institute, Pittsburgh, PA, USA. ·Clin Cancer Res · Pubmed #22912390.

ABSTRACT: Why human tumors grow infiltrated by specific antitumor T cells has been a mystery attributed to negative factors released directly by the tumor or indirectly through immune intermediaries. The frequency and phenotype of myeloid-derived suppressor cells in the peripheral blood of melanoma patients and healthy donors are surprisingly similar.

5 Article Helper activity of natural killer cells during the dendritic cell-mediated induction of melanoma-specific cytotoxic T cells. 2011

Wong, Jeffrey L / Mailliard, Robbie B / Moschos, Stergios J / Edington, Howard / Lotze, Michael T / Kirkwood, John M / Kalinski, Pawel. ·Department of Surgery, University of Pittsburgh, University of Pittsburgh Cancer Institute, Pittsburgh, PA 15213-1863, USA. ·J Immunother · Pubmed #21389871.

ABSTRACT: Natural killer (NK) cells have been shown to mediate important immunoregulatory "helper" functions in addition to their cytolytic activity. In particular, NK cells are capable of preventing maturation-related dendritic cell (DC) "exhaustion," inducing the development of "type-1 polarized" mature DCs (DC1) with an enhanced ability to produce interleukin (IL)-12p70, a factor essential for type-1 immunity and effective anticancer responses. Here we show that the NK cell-mediated type-1 polarization of DCs can be applied in the context of patients with advanced cancer to enhance the efficacy of DCs in inducing tumor-specific cytotoxic T lymphocytes. NK cells isolated from patients with late-stage (stage III and IV) melanoma responded with high interferon-γ production and the induction of type-1-polarized DCs on exposure to defined combinations of stimulatory agents, including interferon-α and IL-18. The resulting DCs showed strongly-enhanced IL-12p70 production on subsequent T-cell interaction compared with immature DCs (average of 19-fold enhancement) and nonpolarized IL-1β/TNF-α/IL-6/PGE(2)-matured "standard" DCs (average of 215-fold enhancement). Additional inclusion of polyinosinic: polycytidylic acid during NK-DC cocultures optimized the expression of CD80, CD86, CD40, and HLA-DR on the resulting (NK)DC1, increased their CCR7-mediated migratory responsiveness to the lymph node-associated chemokine CCL21, and further enhanced their IL-12-producing capacity. When compared in vitro with immature DCs and nonpolarized standard DCs, (NK)DC1 were superior in inducing functional melanoma-specific cytotoxic T lymphocytes capable of recognizing multiple melanoma-associated antigens and killing melanoma cells. These results indicate that the helper function of NK cells can be used in clinical settings to improve the effectiveness of DC-based cancer vaccines.
