Abstract
Metastatic renal cell carcinoma (mRCC) continues to be associated with high rates of morbidity and mortality. Renal cell carcinoma (RCC) is typically resistant to cytotoxic chemotherapy, and while targeted therapies have activity and prolong progression-free and overall survival, responses are usually not durable. Modulating the immune system with cytokine therapy, vaccine therapy, cell therapy, and checkpoint inhibitors offers hope of prolonged survival. Standard and emerging immune therapy approaches and combinations of immune therapies and other modalities are reviewed.

Abstract
Despite the rapid development of therapeutic modalities for metastatic renal cell carcinoma (mRCC) over the past decade to include a number of targeted antiangiogenic therapies and traditional immunotherapy, such as high-dose interleukin-2 and interferon-α, mRCC continues to be associated with poor prognosis. Currently, several novel immunotherapy agents, such as cancer vaccines, adoptive cell therapy, and checkpoint inhibitors, such as programmed cell death-1 (PD-1 present on T cells), one of its ligands (PD-L1 present on antigen-presenting cells and tumor cells), and cytotoxic T-lymphocyte-associated protein-4 pathways, are being studied in mRCC and are showing promise as important steps in the management of this disease. This review summarizes the current landscape of standard and emerging immune therapeutics and other modalities for mRCC.

Abstract
Programmed cell death-1 (PD-1) is a recognized immune checkpoint. It is frequently upregulated on the T cells that infiltrate tumors, providing an inhibitory signal, which may facilitate immune escape. Blocking antibodies have been developed to interrupt the interaction of PD-1 with its ligands PD-L1/PD-L2, with the goal of increasing the host antitumor immune response. Initial results have been encouraging, with durable responses in both treatment-naive and pretreated patients, along with an acceptable toxicity profile. This tolerability makes PD-1 blockade an excellent potential partner for combination strategies with the approved targeted agents, such as tyrosine kinase inhibitors (TKIs) and anti-vascular endothelial growth factor (anti-VEGF) antibodies, as well as other investigational immune checkpoint inhibitors or agonist antibodies that may costimulate an immune response. PD-L1 expression on tumor cells and tumor-infiltrating immune cells is also being evaluated as a predictive biomarker of response to treatment. This review summarizes the biological basis, preclinical studies, ongoing trials, and future challenges associated with targeting the PD-1 pathway in renal cell carcinoma.

Abstract
RCC is considered an immunogenic tumor with a prominent dysfunctional immune cell infiltrate, unable to control tumor growth. Evasion of immune surveillance, a process defined immune-editing, leads to malignant progression. The striking improvement of knowledge in immunology has led to the identification of immune checkpoints (such as CTLA-4 and PD-1), whose blockage enhances the antitumor immunity. The interaction between PD-1, an inducible inhibitory receptor expressed on lymphocytes and DCs, and PD-L1 ligand, expressed by tumor cells, results in a down-regulation of the T-cell response. Therefore, the PD-1/PD-L1 axis inhibition by targeted-antibodies, increasing the T-cell proliferation and cytotoxicity, represents a promising mechanism to stimulate the anti-tumor activity of the immune system, improving the outcomes of cancer patients. Several PD-1 and PD-L1 inhibitors have been evaluated in different tumor types, showing promising results. The interesting correlation between lymphocytes PD-1 expression and RCC advanced stage, grade and prognosis, as well as the selective PD-L1 expression by RCC tumor cells and its potential association with worse clinical outcomes, have led to the development of new anti PD-1/PD-L1 agents, alone or in combination with anti-angiogenic drugs or other immunotherapeutic approaches, for the treatment of RCC. In this review we discuss the role of PD-1/PD-L1 in RCC, focusing on the biological rationale, current clinical studies and promising therapeutic perspectives to target the PD-1 pathway.

Abstract
In recent years, an improved understanding of renal cell carcinoma (RCC) tumour biology has resulted in major advances in the treatment of patients with metastatic RCC (mRCC). Although immunotherapy with interleukin-2 and interferon-α was once the standard of care for mRCC, the introduction of novel agents targeting angiogenesis and signal transduction pathways has markedly improved patient outcomes. However, targeted agents rarely induce complete responses, and patients eventually develop resistance to therapy, prompting consideration of novel therapeutic approaches and a resurgence of interest in immunotherapy for RCC. Phase I/II trials of vaccination with allogeneic dendritic cell/tumour fusions in patients with mRCC have demonstrated immunological and clinical responses in some patients, and T-cell modulating agents (e.g. antibodies against programmed death 1 and cytotoxic T lymphocyte-associated antigen-4, or soluble lymphocyte activation gene-3) and dendritic cell-activating toll-like receptor agonists have also shown encouraging evidence of efficacy in early-phase clinical trials. These early studies suggest that immunotherapy may continue to be an effective approach for patients with mRCC. As such, a number of other strategies are currently under investigation, including adoptive cell transfer (ACT) with T cells modified to target proteins expressed by renal tumours such as MAGE-A3/12, DR4 and TRAIL, and ACT with autologous natural killer cells. Results from trials of novel immunotherapies are encouraging, with data from other indications helping to facilitate development. To realise the full benefit for patients, it is likely that immunotherapy will need to be combined with targeted agents or other agents. Novel therapies used in combination or sequentially have the potential to improve outcomes in mRCC, and results from ongoing/planned trials will shape future therapy.

Abstract
Metastatic renal cell carcinoma (MRCC) remains a challenging malignancy to treat. Cancer immunotherapies have been extensively explored in melanoma and RCC as they poorly respond to conventional cytotoxic agents but show responses to a variety of immunologic agents. The recent considerable success of T cell-based immunotherapy in melanoma warrants further efforts to apply this treatment to other cancers including MRCC. Although RCC is an immunosensitive cancer, similar attempts in MRCC have shown a very limited success. In this review, we summarize the clinical data on T cell-based immunotherapies for MRCC showing the modest success that has been achieved to date. More importantly, we discuss potential strategies for improving its efficacy for the treatment of MRCC in light of the important achievements for treating metastatic melanoma. In particular, the growing evidence of success by combining expanded tumor-infiltrating lymphocytes with lymphodepletion merits investigation in MRCC. Identifying new RCC-associated antigens, optimized methods, and conditions for detection, isolation, and/or modification and expansion of tumor-specific T cells are all important strategies to be pursued for improving T cell-based immunotherapy of MRCC.

Defective infiltration of natural killer cells in MICA/B-positive renal cell carcinoma involves beta(2)-integrin-mediated interaction. Neoplasia 2009; 11:662-71.

Abstract
We have explored MICA/B expression and its relationship with innate inflammatory infiltrate in renal cell carcinoma (RCC). The expression of MICA/B, CD16, CD56, and CD68 in 140 RCC lesions contained in a tissue microarray (TMA) was investigated by immunohistochemistry. MICA/B gene and protein expressions in Caki-1 cells were analyzed by reverse transcription-polymerase chain reaction and flow cytometry, respectively. Natural killer (NK) cells were studied by flow cytometry. All the RCC lesions (n = 140) were MICA/B-positive. MICA/B was mainly expressed in the cytoplasm of tumor cells, whereas stromal cells were negative. Renal cell carcinoma lesions showed low NK cell infiltration, although they were rich in CD16(+)CD56(-) cells, strongly resembling macrophages. CD16(+) macrophage infiltration was more frequently detectable in metastatic lesions compared with primary tumors (P = .0223) and was associated with poor RCC differentiation (P = .007). To investigate mechanisms potentially underlying the lack of NK cells infiltration into MICA/B-positive RCC lesions, we used Caki-1 RCC cells. Caki-1 expressed MICA and MICB genes. However, MICA protein was not detectable in Caki-1 cells, whereas MICB protein was detectable in their cytoplasm and on the cell membrane. Coculture of peripheral blood mononuclear cells with Caki-1, K562, HCT116, respectively, resulted in CD56(+)CD16(+) NK cells deletion without affecting CD56(+)/CD16(-) NK subset and immature NK cells generated in vitro from CD34(+) cells. Natural killer cell apoptosis seemed to be preferentially triggered by cancer cells because HLA-A0201(+) NK cells were only marginally affected by allogeneic HLA-A0201(-) peripheral blood mononuclear cells. Caki-1 cell-mediated NK cell apoptosis was reduced by an anti-beta(2)-integrin (CD18) monoclonal antibody but was NKG2D-, granule exocytosis-, and caspase-independent.

Abstract
BACKGROUND The management of metastatic renal cancer remains a therapeutic challenge. Conventional cytotoxic chemotherapy is rarely effective, and the most promising approaches appear to lie in the field of immunotherapy. METHODS The authors review the literature regarding current and investigational immunotherapy approaches to the management of metastatic renal cancer. RESULTS The mechanism of action, methods of delivery, efficacy, and side effect profile of the cytokines IL-2 and interferon alfa are discussed. The role of investigational approaches such as tumor vaccines, antibody-based therapy, lymphocyte infusions, and bone marrow transplantation is addressed. The rationale for nephrectomy as an adjunctive procedure to immunotherapy is also discussed. CONCLUSIONS Ongoing laboratory investigation of the cause of the immune deficit in patients with metastatic renal cell cancer will result in the development of novel therapies to enhance tumor cell recognition as well as host antitumor response. Translation of laboratory findings into the clinic will be facilitated by the presence of an already well-developed infrastructure for the performance of clinical trials for patients with this difficult diagnosis.

Abstract
A technique was developed to measure the frequency of natural killer cell precursors (NKpf) in human peripheral blood mononuclear cell (PBMC) samples. Functional maturity of NK cells was reflected in their ability to lyse target cells from the K562 cell line. During the development of the technique, venous blood was taken from one healthy adult and assayed at different times to avoid individual variation. The technique was based on the principle of limiting dilution analysis. The NKpf assay was set up with a range of cell dilutions from 40,000 to 625 per 100 microl/well in 96-well culture plates. At the end of the culture period, the K562 cell line labelled with europium (Eu-K562) was added and the Eu-release was measured in culture supernatants using time-resolved fluorometry. The NKpf value differed between individuals and was influenced by the length of time in culture, being maximal at day 5. Maturation of NKp required the continuous presence of recombinant interleukin 2 (rIL-2), or rIL-15, both being equally effective. In the absence of cytokines, the functional NK cells declined rapidly beyond 24 h in culture. Irradiated allogeneic cells appeared to substitute in part for cytokines, but the numbers of allo-activated NKpf were lower than those observed when allo-activated NKpf were cultured with rIL-2. This suggested selective activation by the allogeneic stimulus of subsets of NKp or rIL-2-rescue of NKp subsets destined for apoptotic cell death. Alternatively, the increased frequency could have been attributable to activation of precursors of natural killer-T cells (NK-Tp). This assay is suitable for estimating the total number of precursors of functional NK cells in the blood of patients.

Abstract
The chemo-immunotherapy (CIT) and chemo-adoptive immunotherapy (CAIT) regimens tested in the past decade are summarized. From them we have learned a great deal about the interactions between various chemotherapeutic agents, immune modulating agents and effector cells. The most commonly reported result in multi-modality experiments with CAIT has been a synergistic enhancement in antitumor activity. Clinical trials usually demonstrated improvement in patient quality of life, an extension of survival time, and occasional complete regression of tumor. In many animal models, this enhancement often meant the complete regression and apparent cure of tumor in the animal. One mechanism by which this synergistic enhancement takes place appears to be a suppression of tumor-associated suppressor T cell activity by the chemotherapeutic agents, thereby inducing enhanced cytolytic activity against tumor by the adoptively transferred, activated effector cells. In CAIT the most commonly used drug has been cyclophosphamide. In CIT a wide variety of chemotherapy agents have been used but none of the clinical trials made use of cyclophosphamide. Thus, direct comparisons are not possible. Suggestive of the intricate regulatory processes involved, many CIT studies indicate a synergy only when specific doses of chemotherapy and immunotherapy agents are given, and in a specific sequence. CIT has become less toxic, is being handled on a cost-effective outpatient basis, while maintaining similar objective response rates to earlier inpatient treatments. In the future, CAIT and CIT will probably have an increasing role in the management of patients with specific cancers.

Abstract
Immunotherapy of cancer is entering into a new phase of active investigation both at the pre-clinical and clinical level. This is due to the exciting developments in basic immunology and tumour biology that have allowed a tremendous increase in our understanding of mechanisms of interactions between the immune system and tumour cells. This review briefly summarizes the state of the art in basic tumour immunology before discussing the clinical applications of the new concepts in the clinical setting. Clinical approaches are diverse but can now be based on strong scientific rationales. The analysis of the available clinical results suggests that, despite some disappointments, there is room for optimism that both active immunotherapy (vaccination) and adoptive immunotherapy may soon become part of the therapeutic arsenal to combat cancer in a more efficient way.
