Abstract
INTRODUCTION Despite a recent increase in US FDA-approved treatments, genitourinary malignancies remain a source of significant morbidity and mortality. One focus of research is the use of therapeutic cancer vaccines in these diseases, and a significant body of clinical trial experience now exists for refining vaccine strategies to enhance antitumor efficacy and develop immune-based combination regimens. AREAS COVERED In recent years, clinical data from multiple trials in genitourinary malignancies have enhanced our understanding of the potential for immunotherapy in these cancers. There are also emerging clinical strategies that combine cancer vaccines with chemotherapy, radiation, androgen-deprivation therapy and immune checkpoint inhibitors. This review is based on a search of relevant literature for data presented over the past 5 years from clinical trials of cancer vaccines in prostate, bladder and renal carcinomas. EXPERT OPINION In the coming years, clinical trials informed by decades of preclinical data and emerging clinical data will help to define the role of immunotherapy in genitourinary malignancies. Combination strategies that capitalize on the immune properties of standard treatments will bring greater clinical benefits, and immune-based combinations will likely be moved to the neoadjuvant setting, where they may have optimal clinical impact.

Abstract
ABSTRACT Radiation therapy and immunotherapy in partnership may have the capability of delivering a therapeutic effect exceeding the sum of its parts. The possible relationship has been demonstrated in murine models and has been extended to a variety of clinical trials. Though the standard notion of whole body radiation therapy is immunosuppressive, there is growing evidence toward the contrary for focal radiation therapy. Furthermore, if immunotherapeutic techniques can retune the immune system against cancerous cells, they should have obvious benefits for advanced treatments moving forward. Herein, we explore the promise in combining radiation therapy and immunotherapy with distinct focus on potential morbidities and toxicities through analysis of completed clinical trials.

Multi-institutional phase I study of low-dose ultra-fractionated radiotherapy as a chemosensitizer for gemcitabine and erlotinib in patients with locally advanced or limited metastatic pancreatic cancer. Radiother Oncol 2014; 113:35-40. [PMID: 25441058 DOI: 10.1016/j.radonc.2014.08.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Revised: 08/07/2014] [Accepted: 08/24/2014] [Indexed: 11/22/2022]
Abstract
PURPOSE Gemcitabine (G) has been shown to sensitize pancreatic cancer to radiotherapy but requires lower doses of G and thus delays aggressive systemic treatment, potentially leading to distant failure. We initiated a phase I trial combining ultra-fractionated low-dose radiotherapy with full dose G and erlotinib in the treatment of patients with advanced pancreatic cancer. METHODS Patients with locally advanced or metastatic pancreatic cancer confined to the abdomen and an ECOG performance status (PS) of 0-1 who had received 0-1 prior regimens (without G or E) and no prior radiotherapy were eligible. Patients were treated in 21 day cycles with G IV days 1 & 8, E once PO QD, and twice daily RT fractions separated by at least 4h on days 1, 2, 8, and 9. Whole abdominal RT fields were used. Primary endpoint was to define dose limiting toxicity (DLT) and the maximum tolerated dose (MTD). RESULTS 27 patients (median age 64 years and 15 male) were enrolled between 11/24/08 and 4/12/12. 1 patient withdrew consent prior to receiving any protocol therapy. 17 patients had a PS of 1. The majority of patients were stage IV. One DLT was noted out of 7 patients at dose level (DL) 1. Subsequently no DLTs were noted in 3 patients each enrolled at DL2-4 or 11 patients in the expansion cohort. The majority of grade 3 toxicities were hematologic with 1 grade 5 bowel perforation in dose level 1 in cycle 4. Best response in 24 evaluable patients: PR (8), stable (15), PD 1. Median survival for the entire group was 9.1 months. CONCLUSION This phase I study combining low-dose ultra-fractionated RT as a sensitizer to full dose G plus E was well tolerated with encouraging efficacy. This represents a novel strategy worthy of further investigation in advanced pancreatic cancer patients.

Abstract
Advances in our understanding of the complex mechanisms of immune regulation and the interactions between tumor cells and the immune system have provided a solid foundation for advancing cancer immunotherapy and have inspired novel therapeutic strategies. Optimizing the effectiveness of immunotherapy will require targeting the antitumor immune response at multiple levels, and this may be achieved through synergistic combinations. Examples include combining two cancer vaccines to achieve a "prime and boost" effect, combining two immune checkpoint inhibitors, combining immunotherapy with targeted agents, or combining immunotherapy with low-dose chemotherapy or radiation. Immune checkpoint inhibitors, such as ipilimumab and nivolumab, will likely play an important role in the future of immunotherapy. The ability to block key pathways by which tumor cells seek to evade or suppress the immune response is critical to realizing the potential of cancer immunotherapy. Other exciting advances include recombinant oncolytic viruses and adoptive transfer of chimeric antigen receptor T cells. However, many challenges remain if durable tumor eradication with minimal toxicity is to be achieved in a broader population of cancer patients.

Abstract
Since the mid-1990s, dendritic cells have been used in clinical trials as cellular mediators for therapeutic vaccination of patients with cancer. Dendritic cell-based immunotherapy is safe and can induce antitumour immunity, even in patients with advanced disease. However, clinical responses have been disappointing, with classic objective tumour response rates rarely exceeding 15%. Paradoxically, findings from emerging research indicate that dendritic cell-based vaccination might improve survival, advocating implementation of alternative endpoints to assess the true clinical potency of dendritic cell-based vaccination. We review the clinical effectiveness of dendritic cell-based vaccine therapy in melanoma, prostate cancer, malignant glioma, and renal cell carcinoma, and summarise the most important lessons from almost two decades of clinical studies of dendritic cell-based immunotherapy in these malignant disorders. We also address how the specialty is evolving, and which new therapeutic concepts are being translated into clinical trials to leverage the clinical effectiveness of dendritic cell-based cancer immunotherapy. Specifically, we discuss two main trends: the implementation of the next-generation dendritic cell vaccines that have improved immunogenicity, and the emerging paradigm of combination of dendritic cell vaccination with other cancer therapies.

Abstract
Mononuclear phagocytes are major players in diverse pathological conditions which include chronic inflammatory diseases, infection, autoimmunity, atherosclerosis, metabolic disorders, and cancer. Plasticity is a fundamental property of cells of the monocyte-macrophage lineage and a variety of modulators profoundly affect monocytes and macrophages. Tumor-associated macrophages (TAMs) provide a paradigm for macrophage plasticity and anticancer therapeutic modalities (chemotherapy, radiotherapy, and immunotherapy) profoundly affect their function. The development of innovative strategies targeting cells of the monocyte-macrophage lineage may pave the way to innovative therapies for a wide range of diseases.

Abstract
Despite major advances in the treatment of ovarian cancer over the past two decades, it is still an incurable disease and requires the development of better treatment strategies. In recent years, we have developed a greater understanding of tumor immunology and the interactions between tumors and the immune system. This has led to the emergence of cancer immunotherapy as the fourth treatment modality in cancer. In this article, we address the principles of immunotherapy and different approaches that have been investigated over the past decade and discuss the future of immune therapy in ovarian cancer.

Abstract
Conceptually, the immune system may profoundly influence the efficacy of radiation therapy. Compelling evidence has recently emerged revealing the capacity of local radiation therapy (RT) to induce antitumor immune responses and sparked interest in combining RT with immunotherapy to promote tumor-specific immunity. A Listeria monocytogenes (Lm)-based cancer vaccine engineered to express tumor-associated antigen has been shown to effectively retard tumor growth by cell-mediated immune mechanisms. We hypothesized that combining RT and Lm vaccine will result in synergistic effects that enhance tumor control. Collectively, our data demonstrate that combination therapy significantly delayed B16 melanoma tumor growth by a mechanism partly dependent on CD8+ T cells. Radiotherapy and Lm vaccine each induce different aspects of antitumor immunity, resulting in an overall increase in intratumoral numbers of activated T cells, antigen-specific CD8+ T cells, natural killer (NK) cells and levels of effector molecules, such as interferon γ (IFNγ) and granzyme B. Thus, radiation and Lm vaccine combination therapy is a promising new strategy for the treatment of malignant disease, and further understanding of the mechanisms that underlie efficacy is required to optimize the dosage and schedule for administering the two treatments.

Abstract
Recent work with immunotherapy has shown promising results with treatment of several solid malignancies, and there are several reports of good systemic responses with the combination of immunotherapy and radiation therapy (RT), most notably in advanced melanoma. Given the rapid increase in the use of checkpoint blockade as well as anti-tumor vaccines, we review here the preclinical rationale and ongoing clinical work in combining immunotherapy with RT for small cell lung cancer (SCLC) and thymic tumors. While there are several reports of promising results with the combination of immunotherapy and conventional systemic treatment, we focus here on the ongoing clinical studies that combine immunotherapy with RT, and highlight the emerging data for this multimodality approach as well as key preclinical and clinical issues that remain to be addressed. With regards to SCLC, trials exploring to the combination of immunotherapy and RT are already ongoing, but clinical studies for this combination in thymoma are lacking.

Abstract
Immunotherapy has revolutionized the treatment of non-small cell lung cancer (NSCLC). However, thus far, its use has only been established in patients with advanced disease either as first-line therapy in selected patients or following chemotherapy. What is not yet known is how best to incorporate radiation with immunotherapy agents. Many patients with advanced disease can benefit from palliative radiation, but the combination of radiation with immunotherapy has the potential to increase the toxicity of both modalities. Intriguingly, the combination also has the potential to enhance the efficacy of both modalities. For this reason, combining immunotherapy and radiation may help salvage patients with recurrent localized disease who are candidates for re-irradiation. We review the current data evaluating immunotherapy with both palliative radiation as well as definitive re-irradiation in NSCLC.
