Abstract
Outcomes for patients with high-risk neuroblastoma (HR-NBL) are significantly improved with the addition of immunotherapy (dinutuximab + cytokines) following autologous hematopoietic stem cell transplantation (auto-HSCT). We hypothesized that the immune system is not fully reconstituted at the initiation of immunotherapy. To test this hypothesis, we evaluated hematologic and immune subsets in 34 patients with HR-NBL before and after auto-HSCT. We found that absolute T, B, and NK cell counts at the time of immunotherapy were below normal in 80% of patients. Patients with residual disease at the time of transplantation had significantly lower absolute lymphocyte counts (ALC; P = .008), lower CD16+ cell counts (P = .009), and an abnormal ratio of cytokine-releasing to cytotoxic NK cells at the time of dinutuximab treatment. In addition, the preparative regimen used for auto-HSCT predicted immune recovery. Finally, higher total white blood cell count (P = .013) and ALC (P = .013) at 3 months after completion of therapy were measured in patients who remained in remission compared with those who relapsed. Our results indicate that most patients with HR-NBL do not have full immune reconstitution at the time of dinutuximab treatment after auto-HSCT, and that immune recovery may correlate with disease-related outcomes in patients with high-risk disease.

Abstract
INTRODUCTION Current therapeutic approaches for high-risk neuroblastoma (HR-NB) include high-dose chemotherapy, surgery and radiotherapy; interventions that are associated with long and short-term toxicities. Effective immunotherapy holds particular promise for improving survival and quality of life by reducing exposure to cytotoxic agents. GD2, a surface glycolipid is the most common target for immunotherapy. Areas covered: We review the status of anti-GD2 immunotherapies currently in clinical use for neuroblastomas and novel GD2-targeted strategies in preclinical development. Expert commentary: Anti-GD2 monoclonal antibodies are associated with improved survival in patients in their first remission and are increasingly being used for chemorefractory and relapsed neuroblastoma. As protein engineering technology has become more accessible, newer antibody constructs are being tested. GD2 is also being targeted by natural killer cells and T-cells. Active immunity can be elicited by anti-GD2 vaccines. The rational combination of currently available and soon-to-emerge immunotherapeutic approaches, and their integration into conventional multimodality therapies will require further investigation to optimize their use for HR-NB.

Abstract
OBJECTIVE: To systematically review clinical trials evaluating anti-disialoganglioside (GD2) antibodies in treating high-risk neuroblastoma in children. DATA SOURCES: A literature search was conducted in PubMed/MEDLINE, International Pharmaceutical Abstracts, and Cumulative Index of Nursing and Allied Health Literature (all searches 1990-August 2012) using the terms neuroblastoma, immunotherapy, 3F8, ch14.18, and hu14.18. Meeting abstracts presented between 1990 and 2012 from the American Society of Clinical Oncology, European Society for Medical Oncology, the American Society of Pediatric Hematology Oncology, Society of Surgical Oncology, and the American Society of Hematology were also evaluated. STUDY SELECTION AND DATA EXTRACTION: All completed and ongoing clinical trials of anti-GD2 antibodies in neuroblastoma were included. References from selected articles were also reviewed to identify additional citations. DATA SYNTHESIS: In 1999, the results of a Children's Cancer Group trial established that consolidation therapy after induction, surgery, and radiation should include purged autologous stem cell rescue followed by maintenance with isotretinoin. Overall survival at 7 years with this regimen remains below 30%. Over the following decade, antibodies targeting GD2, a surface antigen found on the surface of neuroblastoma cells, have emerged as a major therapeutic development for high-risk neuroblastoma. Anti-GD2 antibodies incite immune-mediated cytotoxicity toward neuroblastoma cells when given as monotherapy or in combination with cytokines such as sargramostim (granulocyte-macrophage colony-stimulating factor) or aldesleukin (interleukin-2). Responses to anti-GD2 agents appear most notable in patients with minimal residual disease following standard therapy. A chimeric preparation, ch14.18, is the only anti-GD2 antibody to be evaluated in a large controlled clinical trial, in which it demonstrated overall survival of 86% at 2 years in patients with high-risk neuroblastoma. Older nonrandomized studies of ch14.18 monotherapy and 3F8, a murine antibody, suggest this survival rate remains between 50 and 85% at 5 years posttreatment. CONCLUSIONS: Multiple GD2-specific monoclonal antibodies have been researched over the last decade in patients diagnosed with high-risk neuroblastoma. One anti-GD2 antibody, ch14.18, was found to significantly improve event-free and overall survival of high-risk neuroblastoma. Therefore, the standard approach to treating high-risk neuroblastoma is likely to undergo a major shift once an anti-GD2 antibody becomes commercially available.

Abstract
Osteosarcoma (OS) is the most common non-hematologic malignant tumor of bone in adults and children. As sarcomas are more common in adolescents and young adults than most other forms of cancer, there are a significant number of years of life lost secondary to these malignancies. OS is associated with a poor prognosis secondary to a high grade at presentation, resistance to chemotherapy and a propensity to metastasize to the lungs. Current OS management involves both chemotherapy and surgery. The incorporation of cytotoxic chemotherapy into therapeutic regimens escalated cure rates from <20% to current levels of 65-75%. Furthermore, limb-salvage surgery is now offered to the majority of OS patients. Despite advances in chemotherapy and surgical techniques over the past three decades, there has been stagnation in patient survival outcome improvement, especially in patients with metastatic OS. Thus, there is a critical need to identify novel and directed therapy for OS. Several Phase I trials for sarcoma therapies currently ongoing or recently completed have shown objective responses in OS. Novel drug delivery mechanisms are currently under phase II and III clinical trials. Furthermore, there is an abundance of preclinical research which holds great promise in the development of future OS-directed therapeutics. Our continuously improving knowledge of the molecular and cell-signaling pathways involved in OS will translate into more effective therapies for OS and ultimately improved patient survival. The present review will provide an overview of current therapies, ongoing clinical trials and therapeutic targets under investigation for OS.

Abstract
PURPOSE Osteosarcoma most commonly recurs in the lung. Based on preliminary data on the antitumor effects of granulocyte-macrophage colony stimulating factor (GM-CSF) in animal models, and promising phase I trials, we embarked on a feasibility study of inhaled GM-CSF in patients with first isolated pulmonary recurrence of osteosarcoma. EXPERIMENTAL DESIGN Forty-three eligible patients received inhaled GM-CSF at doses from 250 to 1,750 microg twice daily on alternate weeks. Following two cycles, patients underwent thoracotomy to resect tumor and analyze pulmonary nodules for expression of Fas/Fas ligand (Fas/FasL), and the presence of dendritic cells by immunostaining for CD1a, clusterin, and S100. Following surgery, patients received 12 additional cycles of therapy on alternating weeks or until progression. Event-free survival and survival, and feasibility of therapy delivery were evaluated. RESULTS Dose escalation to 1,750 microg twice daily was feasible with no dose-limiting toxicity. Mean scores for Fas/FasL in nodules from patients with bilateral recurrence who underwent unilateral thoracotomy pretreatment (using a scoring system of 0-3) were 1.3 and 0.88, respectively, compared with 0.78 and 0.62 in nodules resected following two cycles of therapy. Only 11 of 30 nodules postinhalation were positive for CD1a, 4 of 30 for S100, and 6 of 30 for clusterin. Event-free and overall survival at 3 years were 7.8% and 35.4%, respectively. CONCLUSIONS Inhalation of GM-CSF at doses from 250 to 1,750 microg twice daily on alternate weeks was feasible with low toxicity. However, no detectable immunostimulatory effect in pulmonary metastases or improved outcome postrelapse was seen.

Abstract
B-cell chronic lymphocytic leukemia (CLL) accounts for 95% of chronic leukemia cases and 25% of all leukemia. Despite the prevalence of CLL, progress in its treatment has been only modest over the past three decades. Based upon the ability of fludarabine to produce high-grade remissions especially among patients with low initial tumor mass, and the ability of alkylators to reduce tumor mass, we hypothesized that sequential administration of a limited number of cycles of intermediate-dose cyclophosphamide followed by fludarabine could result in a larger percentage of patients with complete remissions (CRs). In all, 27 of the 49 eligible patients achieved overall responses of CR, unconfirmed complete remission (UCR), or PR, for a total response rate of 55% (95% confidence interval (CI) 40-69%). Considering the confounding medical issues of this patient population with advanced aggressive disease, the regimen was generally well tolerated. This study demonstrates that high-dose cyclophosphamide followed by fludarabine was relatively well tolerated in this group of advanced CLL patients. The study's criterion for testing whether the regimen is sufficiently effective to warrant further investigation was met: 14 (32%) of the first 44 eligible patients achieved CR or UCR.

Abstract
OBJECTIVES We investigated the immune profile of patients with resected Dukes' stage C colorectal cancer (CRC), receiving adjuvant therapy with edrecolomab (Mo17-1A) or first-line 5-fluorouracil (5-FU)-based chemotherapy. PATIENTS AND METHODS Patients received either 5 doses of Mo17-1A over 13 weeks, or 5-FU/leucovorin, or 5-FU/levamisole over 6 and 12 months, respectively. Peripheral blood was collected postoperatively and 4 months after therapy initiation. Peripheral blood mononuclear cells were tested in the autologous mixed lymphocyte reaction (AMLR), for natural killer (NK) and lymphokine-activated killer (LAK) cell activity. Serum cytokines were quantified by ELISA. RESULTS Fifty-two patients entered the study. Postoperatively, they exhibited decreased levels of interleukin (IL)-2, interferon-gamma, IL-12, granulocyte-macrophage colony-stimulating factor and IL-15, low cellular immune responses (AMLR, NK- and LAK-cytotoxicity) and increased levels of IL-1beta, tumor necrosis factor-alpha, IL-6, IL-10 and prostaglandin E(2). After four months of therapy, patients receiving edrecolomab demonstrated enhanced AMLR, NK, LAK activity, increased serum levels of cytokines regulating such responses and reduced levels of acute-phase cytokines and immune suppressors, compared to patients treated with conventional chemotherapy. CONCLUSIONS Postoperative adjuvant therapy with edrecolomab restores the in vivo deficient immune responses of patients with resected Dukes' C CRC despite its clinical ineffectiveness in recent randomized adjuvant trials. These results suggest that further immunological studies with the combination of edrecolomab and chemotherapy are required.

Mirimostim (macrophage colony-stimulating factor; M-CSF) improves chemotherapy-induced impaired natural killer cell activity, Th1/Th2 balance, and granulocyte function. Cancer Sci 2003; 94:814-20.

Abstract
The purpose of this study was to clarify the effects of mirimostim (macrophage colony-stimulating factor; M-CSF) on immunological functions after chemotherapy. The percentage of natural killer (NK) cells in peripheral blood mononuclear cells (PBMCs), NK cell activity, T-helper cell 1/T-helper cell 2 (Th1/Th2) ratio, and superoxide anion production by granulocytes (granulocyte function) were measured as immunological parameters before and after chemotherapy in 44 patients with primary ovarian cancer who received at least three consecutive courses of postoperative chemotherapy. Patients were observed during the first course of chemotherapy, and 39 patients who presented grade III or IV neutropenia were entered into this study and randomly allocated to an M-CSF-administered group (group 1; 19 patients) and a non-M-CSF-administered group (group 2; 20 patients) for the second course. For the third course, a crossover trial was conducted. In the observation period, chemotherapy significantly impaired the immunological parameters. In particular, those parameters were significantly decreased at day 14 compared to the level before chemotherapy. The values of the parameters of group 1 were significantly higher than those of group 2. In the course of chemotherapy during which M-CSF was administered, 19 of the 39 patients presented grade IV neutropenia, and received granulocyte colony-stimulating factor (G-CSF) between days 7 and 14. We compared the changes of those immunological parameters in the M-CSF alone group and the M-CSF + G-CSF group, and found that the concomitant use of G-CSF did not further improve the parameters. These results indicate that chemotherapy markedly impaired the immunological functions, and that the administration of M-CSF significantly improved the impaired immunological functions.

Abstract
Besides cytotoxicity, taxanes induce other biological effects, especially in the immune system. Taxanes have demonstrated immunostimulatory effects against neoplasms, supporting the idea that these agents suppress cancer through several mechanisms and not solely through inhibiting cell division. The purpose of the present study was to evaluate the effect of taxanes (paclitaxel and docetaxel) and investigate their ability in alterating important immunological parameters in breast cancer patients. Thirty women with advanced breast cancer undergoing chemotherapy were randomly assigned into two groups treated with either single agent Paclitaxel or Docetaxel. Sera from patients before the first and after the last treatment cycle and from normal donors were assayed by ELISA for IL-2, IL-1beta, IFN-gamma, GM-CSF, IL-6, TNF-alpha, and PGE2 levels. In these same blood samples, NK and LAK cell activity was tested in the total PBMC population against NK-sensitive K562 tumour targets, respectively, and autologous mixed lymphocyte reaction was tested by (3)H-thymidine proliferation assays. All patients in both groups responded to therapy. Significant differences were observed in the following immune parameters between the control group of healthy blood donors and the pretreatment values of both taxane groups; IL-2, GM-CSF, IFN-gamma levels and NK and LAK cell cytotoxicity were depressed, whereas TNF-alpha and IL-6 levels were raised in breast cancer patients before treatment compared to controls. There were no significant differences between the two treatment groups regarding any of the parameters studied. Both drugs led to increases in MLR values, NK and LAK cell cytotoxicity, and IL-6, GM-CSF, IFN-gamma levels, and decreases for IL-1, TNF, and PGE2 levels. The percentage of these differences was greater for docetaxel in comparison to paclitaxel (P<0.0001). More specifically, docetaxel demonstrated a more pronounced effect on enhancing MLR, NK, LAK activity and IFN-gamma, IL-2, IL-6, and GM-CSF levels, as well as caused more potent reduction in IL-1 and TNF-alpha levels when compared to paclitaxel. The present study indicates that patients responded to treatment of advanced breast cancer with single-agent paclitaxel or docetaxel leads to an increase in serum IFN-gamma, IL-2, IL-6, GM-CSF cytokine levels and enhancement of PBMC NK and LAK cell activity, while they both lead to a decrease of acute phase serum cytokine levels of IL-1 and TNF-alpha. Moreover, the effects of docetaxel are in all the above parameters more pronounced than those of paclitaxel.

Abstract
AIMS We compared two prospective trials of intra-arterial cytokine/chemotherapeutic infusion plus chemoembolization in the treatment of inoperable colorectal liver metastases. MATERIALS AND METHODS One hundred and three patients with disseminated inoperable colorectal liver metastases received intra-arterial chemotherapy with 5-FU and granulocyte-macrophage colony-stimulating factor (GM-CSF) plus chemoembolization via an angiographically positioned hepatic artery catheter. Two different regimens were used in two consecutive studies. Group A: short-term i.a. infusion of 550 mg/m(2)5-FU (days 1-4) plus 80 microg/m(2)GM-CSF (day 1+2) combined with chemoembolization with 25 mg/m(2)melphalan plus Lipiodol and Gelfoam (day 5). Group B: continuous circadian intra-arterially administered 1400 mg/m(2)5-FU infusion plus 60 mg/m(2)i.v. leucovorin and 80 microg/m(2)GM-CSF (day 1+2) combined with chemoembolization with 25 mg/m(2)melphalan plus Lipiodol and Gelfoam (day 3). RESULTS One hundred and three patients (62 male/41 female) with a median age of 59.9 and a median Karnofsky index of 88.5 were treated with 447 cycles of immuno-chemoembolization (group A 299, group B 148 cycles). Fifty-seven percent of these patients had received prior systemic chemotherapy. Side-effects were seen in all patients, mainly upper abdominal pain lasting 1-4 days and grade 1 or 2 vomiting. Systemic side-effects were mild and transient with a very low rate of leukopenia. Using World Health Organization response criteria, the following responses could be demonstrated: group A: CR 2.7%, PR 32.4%, MR 21.6%, SD 12.7%, NR 16.2%; group B: CR 1.0%, PR 42.4%, MR 24.2%, SD 18.2%, NR 12.1%. Time to progression was 7 as compared to 8 months. Median survival was 17 months in group A, whereas it has not been reached after 28 months (P=0.0095) in group B. There was no statistically significant difference between chemo-naive patients and patients who had received prior systemic therapy. CONCLUSION Immuno-chemoembolization combined with 2-day circadian administration of 5-FU is an effective tool in the treatment of disseminated colorectal liver metastases. This regimen is also effective as second-line treatment.

Abstract
In this study we determined the in vivo localization of recombinant proteins expressed by intraperitoneally (i.p.) injected recombinant Semliki Forest virus (SFV) particles. Subsequently, we investigated the influence of i.p. administered SFV particles encoding recombinant murine granulocyte-macrophage colony-stimulating factor (rmGM-CSF) on intraperitoneal recruitment and activation of cells. Finally, the therapeutic effect of SFV-GM-CSF treatment on an i.p. growing ovarian tumor was determined. Intraperitoneal injections of recombinant SFV particles encoding the reporter protein luciferase resulted in a high level of luciferase activity in cells of the peritoneal lining and tumor cells in the peritoneal cavity. Low levels of luciferase activity were found in liver, spleen and lungs. Injection of SFV-GM-CSF particles resulted in a slight increase in the number of peritoneal macrophages and in a significant increase in the number of neutrophils. In contrast to multiple i.p. injections with commercially available recombinant GM-CSF, i.p. injected SFV-GM-CSF particles activated the macrophages to tumor cytotoxicity. Although treatment of tumor-bearing mice with SFV-GM-CSF particles did not result in prolonged survival, tumor growth was inhibited for 2 weeks. Our findings indicate that macrophage-activating cytokines expressed by the efficient and safe recombinant SFV system when administered i.p. may provide an immunotherapeutic treatment modality additional to current chemotherapeutic treatment of intraperitoneally growing cancers.

Abstract
Abstract
To develop a new immunotherapy for multiple myeloma, we have generated a monoclonal antibody (MoAb) that detects a human plasma cell-specific antigen, HM1.24. Our previous study has shown that mouse anti-HM1.24 MoAb inhibits the proliferation of human myeloma cells implanted into severe combined immunodeficiency mice. In this report, we evaluated the antitumor activity of the humanized anti-HM1.24 MoAb (IgG1κ), which was constructed by grafting the complementarity-determining regions. In contrast to the parent mouse MoAb, humanized anti-HM1.24 MoAb mediated antibody-dependent cellular cytotoxicity (ADCC) against both myeloma cell lines and myeloma cells from patients in the presence of human peripheral blood mononuclear cells (PBMCs). The PBMCs from untreated myeloma patients exhibited ADCC activity as efficiently as those of healthy donors. Although decreased ADCC activity of PBMCs was observed in patients who responded poorly to conventional chemotherapy, it could be significantly augmented by the stimulation with interleukin-2 (IL-2), IL-12, or IL-15. There was a strong correlation between the percentage of CD16+ cells and ADCC activity in the PBMCs of myeloma patients. Moreover, peripheral blood stem cell collections from myeloma patients contained higher numbers of CD16+ cells than PBMCs and exhibited ADCC activity that was enhanced by IL-2. These results indicate that humanized anti-HM1.24 MoAb has potential as a new therapeutic strategy in multiple myeloma and that treatment of effector cells with immunomodulating cytokines can restore the effect of humanized anti-HM1.24 MoAb in patients with diminished ADCC activity.
