Abstract
Background Cancer has surpassed infectious diseases and heart ailments, taking the top spot in the disease hierarchy. Cervical cancer is a significant concern for women due to high incidence and mortality rates, linked to the human papillomavirus (HPV). HPV infection leads to precancerous lesions progressing to cervical cancer. The cervix's external os, near the vagina, hosts various microorganisms. Evidence points to the link between vaginal microbiota and HPV-induced cervical cancer. Cervical cancer onset aligns with an imbalanced Th1/Th2 immune response, but the role of vaginal microbiota in modulating this imbalance is unclear. Methods In this study, we collected vaginal samples from 99 HPV-infected patients across varying degrees of lesions, alongside control groups. These samples underwent bacterial DNA sequencing. Additionally, we employed Elisa kits to quantify the protein expression levels of Th1/Th2 cytokines IL2, IL12, IL5, IL13, and TNFa within the centrifuged supernatant of vaginal-cervical secretions from diverse research subjects. Subsequently, correlation analyses were conducted between inflammatory factors and vaginal microbiota. Results Our findings highlighted a correlation between decreased Lactobacillus and increased Gardenerella presence with HPV-induced cervical cancer. Functionally, our predictive analysis revealed the predominant enrichment of the ABC transporter within the vaginal microbiota of cervical cancer patients. Notably, these microbiota alterations exhibited correlations with the production of Th1/Th2 cytokines, which are intimately tied to tumor immunity. Conclusions This study suggests the potential involvement of vaginal microbiota in the progression of HPV-induced cervical cancer through Th1/Th2 cytokine regulation. This novel insight offers a fresh perspective for early cervical cancer diagnosis and future prevention strategies.

[PMID: 35219004 DOI: 10.1016/j.cyto.2022.155836] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Revised: 01/15/2022] [Accepted: 02/17/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND Interferon-γ (IFN-γ) is a pleiotropic immunomodulatory cytokine. Because of its contradictory and even dualistic roles in malignancies, its potential as a biomarker remains to be unraveled. AIM To evaluate the prognostic significance of serum IFN-γ in hormonally treated breast cancer patients. MATERIAL AND METHODS The study included 72 premenopausal breast cancer patients with known clinicopathological characteristics. All patients received adjuvant hormonal therapy based on hormone receptor-positivity. The median follow-up period was 93 months. IFN-γ serum protein levels were determined by quantitative ELISA. Prognostic performance was evaluated by the receiver operating characteristic (ROC), Cox proportional hazards regression and Kaplan-Meier analyses. Classification of patients into IFN-γlow and IFN-γhigh subgroups was performed by the use of the outcome-oriented cut-off point categorization approach. RESULTS The best prognostic performance was achieved by IFN-γ (AUC = 0.24 and p = 0.01 for distant events, AUC = 0.29 and p = 0.01 for local and distant events combined). Age and IFN-γ were prognostically significant in instances of all types of outcomes and IFN-γ was the independent prognostic parameter (Cox regression). There was a significant difference between IFN-γ values of patients without any events and those with distant metastases (Mann-Whitney test, p = 0.007). IFN-γ levels correlated significantly with nodal status and tumor stage (Spearman's rank order, r = -0.283 and r = -0.238, respectively). Distant recurrence incidence was 4% for the IFN-γhigh subgroup and 33% for the IFN-γlow subgroup (Kaplan-Meier analysis). CONCLUSIONS Raised serum IFN-γ levels associate independently with favorable disease outcome in hormonally dependent breast cancer.

Abstract
Objective Dexmedetomidine has sympatholytic, anti-inflammatory, and analgesic effects and may exert anti-tumor effect by acting on α2A adrenoreceptor. We investigated whether perioperative dexmedetomidine preserves immune function in patients undergoing uterine cancer surgery. Methods One hundred patients were randomly assigned to the control or dexmedetomidine groups (50 patients each). Dexmedetomidine was infused at rates of 0.4 μg/kg/h intraoperatively and 0.15 μg/kg/h during the first 24 h postoperatively. The primary outcome was natural killer (NK) cell activity, which was measured preoperatively and 1, 3, and 5 days postoperatively. The inflammatory response was measured by interleukin-6, interferon-γ, and neutrophil/lymphocyte ratio, and pain scores and opioid consumption were assessed. Cancer recurrence or metastasis and death were evaluated 2 years postoperatively. Results NK cell activity decreased postoperatively in both groups and changes over time were not different between groups (P=0.496). Interferon-γ increased postoperatively in the dexmedetomidine group, whereas it maintained at the baseline value in the control group. Change in interferon-γ differed significantly between groups (P=0.003). Changes in interleukin-6 and neutrophil-lymphocyte ratio were comparable between groups. Both pain score with activity during the first 1 h and opioid consumption during the first 1–24 h postoperatively were lower in the dexmedetomidine group. Rates of cancer recurrence/metastasis (16.3% vs. 8.7%, P=0.227) and death within 2 years postoperatively (6.7% vs. 2.2%, P=0.318) were not different between groups. Conclusions Perioperative dexmedetomidine had no favorable impacts on NK cell activity, inflammatory responses, or prognosis, whereas it increased interferon-γ and reduced early postoperative pain severity and opioid consumption in uterine cancer surgery patients.

Oncotarget 2020; 11:3315-3349. [PMID: 32934776 PMCID: PMC7476732 DOI: 10.18632/oncotarget.27709] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 07/27/2020] [Indexed: 01/04/2023] Open
Abstract
SH7139, the first of a series of selective high affinity ligand (SHAL) oncology drug candidates designed to target and bind to the HLA-DR proteins overexpressed by B-cell lymphomas, has demonstrated exceptional efficacy in the treatment of Burkitt lymphoma xenografts in mice and a safety profile that may prove to be unprecedented for an oncology drug. The aim of this study was to determine how frequently the HLA-DRs targeted by SH7139 are expressed by different subtypes of non-Hodgkin’s lymphoma and by other solid cancers that have been reported to express HLA-DR. Binding studies conducted with SH7129, a biotinylated analog of SH7139, reveal that more than half of the biopsy sections obtained from patients with different types of non-Hodgkin’s lymphoma express the HLA-DRs targeted by SH7139. Similar analyses of tumor biopsy tissue obtained from patients diagnosed with eighteen other solid cancers show the majority of these tumors also express the HLA-DRs targeted by SH7139. Cervical, ovarian, colorectal and prostate cancers expressed the most HLA-DR. Only a few esophageal and head and neck tumors bound the diagnostic. Within an individual’s tumor, cell to cell differences in HLA-DR target expression varied by only 2 to 3-fold while the expression levels in tumors obtained from different patients varied as much as 10 to 100-fold. The high frequency with which SH7129 was observed to bind to these cancers suggests that many patients diagnosed with B-cell lymphomas, myelomas, and other non-hematological cancers should be considered potential candidates for new therapies such as SH7139 that target HLA-DR-expressing tumors.

Abstract
The modulation of the host innate immune system is a well-established carcinogenesis feature of several tumors, including human papillomavirus- (HPV-) related cancers. This virus is able to interrupt the initial events of the immune response, including the expression of Toll-like receptors (TLRs), cytokines, and inflammation. Both TLRs and cytokines play a central role in HPV recognition, cell maturation and differentiation as well as immune signalling. Therefore, the imbalance of this sensitive control of the immune response is a key factor for developing immunotherapies, which strengthen the host immune system to accomplish an efficient defence against HPV and HPV-infected cells. Based on this, the review is aimed at exposing the HPV immune evasion mechanisms involving TLRs and cytokines and at discussing existing and potential immunotherapeutic TLR- and cytokine-related tools.

Abstract
IFN-γ plays a crucial role in anti-tumor responses and also induces expression of PD-L1, a well-established inhibitor of anti-tumor immune function. Understanding how molecular signaling regulates the function of IFN-γ might improve its anti-tumor efficacy. Here, we show that the tumor expression of IFN-γ expression alone has no significant prognostic value in patients with locally advanced lung adenocarcinoma. Surprisingly, patients with tumors expressing both IFN-γ and PD-L1 have the best prognosis compared to those with tumors expressing IFN-γ or PD-L1 alone. Transcriptome analysis demonstrated that tumor tissues expressing IFN-γ display gene expression associated with suppressed cell cycle progression and expansion. Unexpectedly this profile was observed in PD-L1+ but not PD-L1- tumors. The current concept is that PD-L1 functions as a shield protecting tumor cells from cytolytic T cell (CTL)-mediated anti-tumor progression. However, our data indicate that PD-L1 expression in the presence of IFN-γ might serve as biomarker for the sensitivity of tumors to the inhibitory effect of IFN-γ. Mechanistic analysis revealed that in lung adenocarcinoma cells IFN-γ-induced activation of JAK2-STAT1 and PI3K-AKT pathways. The activation of JAK2-STAT1 is responsible for the anti-proliferative effect of IFN-γ. Inhibition of PI3K downregulated PD-L1 expression and enhanced the anti-proliferative effect of IFN-γ, suggesting that blockade of PI3K might maximize the IFN-γ-mediated anti-tumor effect. Our findings provide evidence for crosstalk between JAK2-STAT1 and PI3K-AKT pathways in response to IFN-γ in lung adenocarcinoma and have implications for the design of combinatorial targeted therapy and immunotherapy for the treatment of lung adenocarcinoma.

A Unique Cellular and Molecular Microenvironment Is Present in Tertiary Lymphoid Organs of Patients with Spontaneous Prostate Cancer Regression. Front Immunol 2017; 8:563. [PMID: 28567040 PMCID: PMC5434117 DOI: 10.3389/fimmu.2017.00563] [Citation(s) in RCA: 47] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Accepted: 04/27/2017] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVE Multiple solid cancers contain tertiary lymphoid organs (TLO). However, it is unclear whether they promote tumor rejection, facilitate tumor evasion, or simply whether they are a byproduct of chronic inflammation. We hypothesize that although chronic inflammation induces TLO formation, the tumor milieu can modulate TLO organization and functions in prostate cancer. Therefore, our study seeks to elucidate the cellular and molecular signatures in unique prostatectomy specimens from evanescent carcinoma patients to identify markers of cancer regression, which could be harnessed to modulate local immunosuppression or potentially enhance TLO function. METHODS We used multicolor immunofluorescence to stain prostate tissues, collected at different stages of cancer progression (prostatic intraepithelial neoplasia, intermediate and advanced cancer) or from patients with evanescent prostate carcinoma. Tissues were stained with antibodies specific for pro-inflammatory molecules (cyclooxygenase 2, CXCL10, IL17), tumor-infiltrating immune cells (mature DC-LAMP+ dendritic cells, CD3+ T cells, CD3+Foxp3+ regulatory T cells (Treg), T bet+ Th1 cells, granzyme B+ cytotoxic cells), and stromal cell populations (lymphatic vessels, tumor neovessels, high endothelial venules (HEV), stromal cells), which promote prostate tumor growth or are critical components of tumor-associated TLO. RESULTS Generally, inflammatory cells are located at the margins of tumors. Unexpectedly, we found TLO within prostate tumors from patients at different stages of cancer and in unique samples from patients with spontaneous cancer remission. In evanescent prostate carcinomas, accumulation of Treg was compromised, while Tbet+ T cells and CD8 T cells were abundant in tumor-associated TLO. In addition, we found a global decrease in tumor neovascularization and the coverage by cells positive for cyclooxygenase 2 (COX2). Finally, consistent with tumor regression, prostate stem cell antigen was considerably reduced in TLO and tumor areas from evanescent carcinoma patients. CONCLUSION Collectively, our results suggest that COX2 and Treg are attractive therapeutic targets that can be harnessed to enhance TLO-driven tumor immunity against prostate cancer. Specially, the presence of HEV and lymphatics indicate that TLO can be used as a platform for delivery of cell-based and/or COX2 blocking therapies to improve control of tumor growth in prostate cancer.

Abstract
The human body combats infection and promotes wound healing through the remarkable process of inflammation. Inflammation is characterized by the recruitment of stromal cell activity including recruitment of immune cells and induction of angiogenesis. These cellular processes are regulated by a class of soluble molecules called cytokines. Based on function, cell target, and structure, cytokines are subdivided into several classes including: interleukins, chemokines, and lymphokines. While cytokines regulate normal physiological processes, chronic deregulation of cytokine expression and activity contributes to cancer in many ways. Gene polymorphisms of all types of cytokines are associated with risk of disease development. Deregulation RNA and protein expression of interleukins, chemokines, and lymphokines have been detected in many solid tumors and hematopoetic malignancies, correlating with poor patient prognosis. The current body of literature suggests that in some tumor types, interleukins and chemokines work against the human body by signaling to cancer cells and remodeling the local microenvironment to support the growth, survival, and invasion of primary tumors and enhance metastatic colonization. Some lymphokines are downregulated to suppress tumor progression by enhancing cytotoxic T cell activity and inhibiting tumor cell survival. In this review, we will describe the structure/function of several cytokine families and review our current understanding on the roles and mechanisms of cytokines in tumor progression. In addition, we will also discuss strategies for exploiting the expression and activity of cytokines in therapeutic intervention.

Abstract
Human papillomavirus infection (HPV) and HPV related immune perturbation play important roles in the development of cervical cancer. Since mature dendritic cells (DCs) are potent antigen-presenting cells (APC), they could be primed by HPV antigens against cervical cancers. In this study we were able to generate, maintain and characterize, both phenotypically and functionally, patient specific dendritic cells in vitro. A randomized Phase I trial with three arms--saline control (arm I), unprimed mature DC (arm II) and autologous tumor lysate primed mature DC (arm III) and fourteen patients was conducted. According to WHO criteria, grade 0 or grade one toxicity was observed in three patients. One patient who received tumor lysate primed dendritic cells and later cis-platin chemotherapy showed a complete clinical response of her large metastatic disease and remained disease free for more than 72 months. Our findings indicate that DC vaccines hold promise as adjuvants for cervical cancer treatment and further studies to improve their efficacy need to be conducted.

Abstract
Unfavorable ratios between the number and activation status of effector and suppressor immune cells infiltrating the tumor contribute to resistance of solid tumors to T-cell based therapies. Here, we studied the capacity of FDA and EMA approved recombinant cytokines to manipulate this balance in favor of efficient anti-tumor responses in B16.OVA melanoma bearing C57BL/6 mice. Intratumoral administration of IFN-α2, IFN-γ, TNF-α, and IL-2 significantly enhanced the anti-tumor effect of ovalbumin-specific CD8+ T-cell (OT-I) therapy, whereas GM-CSF increased tumor growth in association with an increase in immunosuppressive cell populations. None of the cytokines augmented tumor trafficking of OT-I cells significantly, but injections of IFN-α2, IFN-γ and IL-2 increased intratumoral cytokine secretion and recruitment of endogenous immune cells capable of stimulating T-cells, such as natural killer and maturated CD11c+ antigen-presenting cells. Moreover, IFN-α2 and IL-2 increased the levels of activated tumor-infiltrating CD8+ T-cells concomitant with reduction in the CD8+ T-cell expression of anergy markers CTLA-4 and PD-1. In conclusion, intratumoral administration of IFN-α2, IFN-γ and IL-2 can lead to immune sensitization of the established tumor, whereas GM-CSF may contribute to tumor-associated immunosuppression. The results described here provide rationale for including local administration of immunostimulatory cytokines into T-cell therapy regimens. One appealing embodiment of this would be vectored delivery which could be advantageous over direct injection of recombinant molecules with regard to efficacy, cost, persistence and convenience.

Abstract
Tumor-infiltrating T and B lymphocytes could have the potential to affect cancer prognosis. The objective of this study was to investigate the prognostic significance of tumor infiltration by CD8 and CD4 T cells, and B lymphocytes in patients with localized gastric cancer. In a retrospective cohort of 82 patients with localized gastric cancer and treated by surgery we quantitatively assessed by immunohistochemistry on surgical specimen, immune infiltrates of IL-17+, CD8+, Foxp3+, Tbet+ T cells and CD20+ B cells both in the tumor core and at the invasive margin via immunohistochemical analyses of surgical specimens. We observed that CD8+ and IL17+ T-cell densities were not significantly associated with gastric cancer prognosis. In contrast, high infiltration of Tbet+ T cells, high numbers of CD20+ B-cell follicles, and low infiltration of Foxp3+ T cells, were associated with better relapse-free survival. Interestingly, treatment with neoadjuvant chemotherapy or histological tumor type (diffuse versus intestinal) did not influence type and density of immune infiltrates or their prognostic value. Immunohistochemical analysis of the gastric cancer stromal microenvironment revealed organized T and B cell aggregates, with strong structural analogies to normal secondary lymphoid organs and which could be considered as tertiary lymphoid structures. Using transcriptomic data from an independent cohort of 365 localized gastric cancer, we confirmed that a coordinated Th1, and B cell stromal gene signature is associated with better outcome. Altogether, these data suggest that tumor infiltration by B and Th1 T cells could affect gastric cancer prognosis and may be used to better define the outcome of patients with localized gastric cancer.

Abstract
Human cancers grow in a microenvironment of stromal, inflammatory and immunocompetent cells which is variable from tumor to tumor. The characterization of the immune contexture, i.e. the type, density and functional orientation of immunocompetent cells, the presence or absence of tertiary lymphoid structures is a major prognostic factor for patients survival and represent a guide and a target for innovative cancer therapies.

Abstract
Several studies have suggested that patients with cervical intraepithelial and invasive neoplasia have reduced levels of Th1 cytokines, and increased levels of Th2 cytokines. Thus, the aim of this study was to delineate the immunological profile associated with lesion progression. Biopsies were obtained from 28 patients with low grade cervical intraepithelial lesions (LSILs), 53 patients with high grade cervical intraepithelial lesions (HSILs), 25 patients with invasive cancer (CA), and 20 healthy controls. Levels of IFN-γ, TNF-α, IL-2, IL-4, IL-10, IL-12, TGF-β1 and TGF-β2 were then assayed by RT-PCR and ELISA for each biopsy sample. For LSILs, higher levels of Th1 cytokines were detected, while HSILs were associated with a Th2 cytokine profile. In contrast, CA tissues were associated with the strongest expression of a Treg cytokine profile. In conclusion the most important contribution of these work is identification of the Treg cytokine profile in HPV progression lesions and in combination, these results suggested that tumor progression is dependent on suppression of cellular immunity.

Abstract
Cervical cancer (CC) occurs more frequently in women who are immunosuppressed, suggesting that both local and systemic immune abnormalities may be involved in the evolution of the disease. Costimulatory CD28 and inhibitory CTLA-4 molecules expressed in T cells play a key role in the balanced immune responses. There has been demonstrated a relation between CD28, CTLA-4, and IFN genes in susceptibility to CC, suggesting their importance in CC development. Therefore, we assessed the pattern of CD28 and CTLA-4 expression in T cells from PB of CC patients with advanced CC (stages III and IV according to FIGO) compared to controls. We also examined the ability of PBMCs to secrete IFN-gamma. We found lower frequencies of freshly isolated and ex vivo stimulated CD4 + CD28+ and CD8 + CD28+ T cells in CC patients than in controls. Loss of CD28 expression was more pronounced in the CD8+ T subset. Markedly increased proportions of CTLA-4+ T cells in CC patients before and after culture compared to controls were also observed. In addition, patients’ T cells exhibited abnormal kinetics of surface CTLA-4 expression, with the peak at 24 h of stimulation, which was in contrast to corresponding normal T cells, revealing maximum CTLA-4 expression at 72 h of stimulation. Of note, markedly higher IFN-gamma concentrations were shown in supernatants of stimulated PBMCs from CC patients. Conclusions: Our report shows the dysregulated CD28 and CTLA-4 expression in PB T cells of CC patients, which may lead to impaired function of these lymphocytes and systemic immunosuppression related to disease progression.

Abstract
Cancer initiation, progression, and invasion occur in a complex and dynamic microenvironment which depends on the hosts and sites where tumors develop. Tumors arising in mucosal tissues may progress in an inflammatory context linked to local viral and/or bacterial infections. At the opposite, tumors developing in immunoprivileged sites are protected from microorganisms and grow in an immunosuppressive environment. In the present review, we summarize and present our recent data on the influence of infectious context and immune cell infiltration organization in human Non-Small Cell Lung Cancers (NSCLC) progression. We show that stimulation of tumor cells by TLR for viral ssRNA, such as TLR7/8, or bacteria, such as TLR4, promotes cell survival and induces chemoresistance. On the opposite, stimulation by TLR3, receptor for double-stranded viral RNA, decreases tumor cell viability and induces chemosensitivity in some lung tumor cell lines. Since fresh lung tumor cells exhibit a gene expression profile characteristic of TLR-stimulated lung tumor cell lines, we suspect that viral and bacterial influence may not only act on the host immune system but also directly on tumor growth and sensitivity to chemotherapy. The stroma of NSCLC contains tertiary lymphoid structures (or Tumor-induced Bronchus-Associated Lymphoid Tissues (Ti-BALT)) with mature DC, follicular DC, and T and B cells. Two subsets of immature DC, Langerhans cells (LC) and interstitial DC (intDC), were detected in the tumor nests and the stroma, respectively. Here, we show that the densities of the three DC subsets, mature DC, LC, and intDC, are highly predictive of disease-specific survival in a series of 74 early-stage NSCLC patients. We hypothesize that the mature DC may derive from local activation and migration of the immature DC--and especially LC which contact the tumor cells--to the tertiary lymphoid structures, after sampling and processing of the tumor antigens. In view of the prominent role of DC in the immune response, we suggest that the microenvironment of early-stage NSCLC may allow the in situ activation of the adaptive response. Finally, we find that the eyes or brain of mice with growing B cell lymphoma are infiltrated with T cells and that the cytokines produced ex vivo by the tumoral tissues have an impaired Th1 cytokine profile. Our work illustrates that the host and external tumor microenvironments are multifaceted and strongly influence tumor progression and anti-tumor immune responses.

Abstract
The interplay between tumors and their immunologic microenvironment is complex and difficult to decipher, but its understanding is of seminal importance for the development of novel prognostic markers and therapeutic strategies. This chapter discusses tumor-immune interactions in several human cancers that illustrate various aspects of this complexity and proposes an integrated scheme of the impact of local immune reactions on clinical outcome. Thus, the fact that a strong infiltration of memory T cells with a Th1 and cytotoxic pattern is the strongest predictor for recurrence and metastasis is exemplified in colorectal cancer in which intratumoral chemokines shape an efficient immune reaction. Based on these data, we propose an immune score that predicts recurrence in early stage (UICC-TNM stage I-II) cancers. Studies on non-small lung cancers have confirmed findings of colorectal cancers and have addressed the question of the sites where antitumor immune reactions may take place. Tertiary lymphoid structures (TLS) adjacent to the tumor nest are sites of intense activity with mature dendritic cells in contact with T cells and germinal-like centers with proliferating B cells. The large number of these TLS being correlated with disease specific and overall survival tempts to postulate that they are privileged sites to mount an efficient antitumor reaction. Inflammation is a major component of human tumors and chronic inflammation is generally of bad prognosis. Head and neck cancers are highly inflammatory and two ways to modulate inflammation in these diseases are presented here: soluble IL-15 receptor α (IL-15 Rα) increases the pro-inflammatory effect of IL-15 and aggravates inflammation resulting in poor prognosis when found at high levels in the plasma of patients. By contrast, infiltration of regulatory T cells is paradoxically beneficial for local control of head and neck tumors, probably by "cooling down" the inflammatory process. The modulation of other aspects of innate immunity may also result in paradoxical effects such as the signaling through Toll like receptors 7 and 8 expressed on lung tumor cells which induce an aggressive tumoral phenotype. Finally, the analysis of primary intraocular lymphoma, which develops in the eye, exemplifies the induction of an antitumor immune reaction in an "immune sanctuary," presenting all the complexities of the tumor-immune interplay in "open" tissues such as the colon or the lung.

Abstract
OBJECTIVE Interferon gamma (IFN-gamma) is a pro-inflammatory cytokine playing a pivotal role in both innate and adaptive immune responses. A single nucleotide polymorphism located in the first intron of the human IFN-gamma gene can influence the secretion of cytokine. Therefore, we aimed to investigate the association of IFN-gamma T/A gene polymorphism with the risk of cervical cancer. DESIGN Case-control study. SETTING Uttar Pradesh State in India. SAMPLE Two hundred cases with histologically proven cancer of the cervix and healthy controls (n = 230), age and ethnicity matched were recruited in this study. METHODS Genotyping was performed for bi-allelic +874 (T/A) polymorphism of IFN-gamma by amplification refractory mutation system method. MAIN OUTCOME MEASURES Low producer IFN-gamma +874 AA genotype was associated with high risk for cervical cancer, which further modulated the increased risk in tobacco users. RESULTS IFN-gamma AA genotype which is low producer of IFN-gamma was associated with increased risk of cervical cancer (OR = 2.43, P = 0.003). Allele A was at 1.54-fold increased risk of cervical cancer (OR=1.54, P = 0.002). The AA genotype showed statistically significant risk with high stage (III + IV) of cervical cancer (OR = 4.99, P = 0.001). In tobacco users, AA genotype showed significantly increased susceptibility to cervical cancer (OR = 5.08, P = 0.010). CONCLUSION Variation in IFN-gamma +874 AA genotype because of ethnicity in north-Indian population may represent an important susceptibility biomarker for cervical cancer risk as well as other diseases and should be explored further.

Abstract
BACKGROUND A diagnosis of breast cancer and treatment are psychologically stressful events, particularly over the first year after diagnosis. Women undergo many demanding and anxiety-arousing treatments such as surgery, radiation and chemotherapy. Psychosocial interventions that promote psychosocial adaptation to these challenges may modulate physiological processes (neuroendocrine and immune) that are relevant for health outcomes in breast cancer patients. METHODS Women with Stages 1-3 breast cancer recruited 4-8 weeks after surgery were randomized to either a 10-week group-based cognitive behavioral stress management (CBSM) intervention or a 1-day psychoeducational control group and completed questionnaires and late afternoon blood samples at study entry and 6 and 12 months after assignment to experimental condition. RESULTS Of 128 women initially providing psychosocial questionnaire and blood samples at study entry, 97 provided complete data for anxiety measures and cortisol analysis at all time points, and immune assays were run on a subset of 85 of these women. Those assigned to a 10-week group-based CBSM intervention evidenced better psychosocial adaptation (lower reported cancer-specific anxiety and interviewer-rated general anxiety symptoms) and physiological adaptation (lower cortisol, greater Th1 cytokine [interleukin-2 and interferon-gamma] production and IL-2:IL-4 ratio) after their adjuvant treatment compared to those in the control group. Effects on psychosocial adaptation indicators and cortisol appeared to hold across the entire 12-month observation period. Th1 cytokine regulation changes held only over the initial 6-month period. CONCLUSIONS This intervention may have facilitated a "recovery or maintenance" of Th1 cytokine regulation during or after the adjuvant therapy period. Behavioral interventions that address dysregulated neuroendocrine function could play a clinically significant role in optimizing host immunologic resistance during a vulnerable period.

Abstract
OBJECTIVE The purpose of this study was to evaluate the association between fibrinogen plasma levels on disease-free patients and overall survival in patients with cervical cancer. STUDY DESIGN Pretherapeutic fibrinogen plasma levels were examined in 313 patients with cervical cancer who were treated at the Department of Obstetrics and Gynecology, Medical University of Vienna. Fibrinogen plasma levels were correlated with clinical-pathologic findings and patient survival. RESULTS Mean (+/- SD) pretherapeutic fibrinogen plasma levels were 417.4 mg/dL (+/- 130.3 mg/dL). Elevated fibrinogen plasma levels were associated with advanced tumor stage (P < .001) and patient age (P < .001), but not with histologic type (P = .4), histologic grade (P = .1), and pelvic lymph node involvement (P = .9). In a multivariate survival analysis, fibrinogen plasma levels (P < .001 and < .001) and lymph node involvement (P < .001 and = .001), but not patients' age (P = .8 and .4) and histologic type (P = .7 and .5) were associated with overall or disease-free survival, respectively. Histologic grade was associated with disease-free (P = .01), but not with overall, survival (P = .2). CONCLUSION Fibrinogen plasma levels are an independent prognostic parameter in patients with cervical cancer.

Abstract
PURPOSE It has been established that the immune system plays an important role in tumor rejection. There is also compelling evidence that immune responses can develop independently of secondary lymphoid organs in tertiary lymphoid structures. We studied the presence and the correlation of tertiary lymphoid structures with clinical outcome in non-small-cell lung cancer (NSCLC), as the prognostic value of these structures in patients with cancer had not yet been established. PATIENTS AND METHODS This retrospective study was performed by immunohistochemistry on paraffin-embedded tissue specimens from 74 patients with early-stage NSCLC. RESULTS Tertiary lymphoid structures were detected in some tumors but not in nontumoral lungs. Thus we called these structures tumor-induced bronchus-associated lymphoid tissue (Ti-BALT). As in lymph nodes, Ti-BALTs were composed of mature dendritic cell (DC)/T-cell clusters adjacent to B-cell follicles and had features of an ongoing immune response. Because the quantitative counting of Ti-BALT was difficult to achieve, we used mature DCs that homed exclusively in Ti-BALT as a specific marker of these structures. Univariate analysis showed that the density of mature DCs was highly associated with a favorable clinical outcome (overall, disease-specific, and disease-free survival), suggesting that Ti-BALT may participate in antitumoral immunity. The density of tumor-infiltrating lymphocytes, in particular, CD4(+) and T-bet(+) Th1 T cells, was profoundly decreased in tumors weakly infiltrated by mature DCs. CONCLUSION The density of mature DCs was found to be a better predictor of clinical outcome than the other parameters tested. The number of tumor-infiltrating mature DCs may identify patients with early-stage NSCLC who have a high risk of relapse.

Abstract
The use of interleukin-18 (IL-18) together with IL-12 induced high levels of IFN-gamma in tumor-bearing mice and regression of liver tumors that was abolished in IFN-gamma((-/-)) mice. Natural killer (NK) and NKT cells were the major producers of IFN-gamma in the livers of mice treated with IL-18 and/or IL-12. Liver NK cells were significantly increased by treatment with IL-18/IL-12, whereas the degree of liver NKT cell TCR detection was diminished by this treatment. Reduction of NK cells with anti-asGM1 decreased the antitumor activity of IL-18/IL-12 therapy and revealed NK cells to be an important component for tumor regression in the liver. In contrast, the antitumor effects of both IL-18 and IL-12 were further increased in CD1d((-/-)) mice, which lack NKT cells. Our data, therefore, show that the antitumor activity induced in mice by IL-18/IL-12 is NK and IFN-gamma dependent and is able to overcome an endogenous immunosuppressive effect of NKT cells in the liver microenvironment. These results suggest that immunotherapeutic approaches that enhance NK cell function while eliminating or altering NKT cells could be effective in the treatment of cancer in the liver.

Abstract
Changes in the human leukocyte antigen (HLA) class I expression and cytokine and chemokine production both by cancer cells and by normal surrounding tissue are believed to be responsible for immune escape and tumor progression. In this study, we compared the tumor expression levels of HLA heavy chain (HLAhc), beta-2-microglobulin (beta2m), chemokines (Interferon-gamma-inducible Protein-10 (IP-10), Interferon-inducible T-cell Alpha-Chemoattractant (I-TAC), Stromal cell-Derived Factor-1 (SDF-1), Macrophage Inflammatory Protein-1-alpha (MIP-1-alpha) and Regulated upon Activation, Normally T-Expressed, and presumably Secreted (RANTES)) and cytokines (Vascular Endothelial Growth Factor (VEGF), Interferon-gamma (IFN-gamma), Interleukin-10 (IL-10), Tumor Growth Factor-beta (TGB-beta)) in primary tumors and adjacent normal tissues from patients with localized and metastatic renal cell carcinoma (RCC) using a quantitative real-time polymerase chain reaction technique. We report that the expression of HLAhc, beta2m and the studied cytokines and chemokines (except for SDF-1) was significantly higher in the tumor (29 samples) than in the normal tissue (14 samples). When we compared the tumor expression levels between patients with localized RCC and patients with advanced metastatic stage, we found that the messenger RNA expression levels of HLAhc and beta2m were much lower in patients with metastatic RCC (6 cases) than in patients with localized cancer (23 cases), with levels similar to those in normal tissue. This was also confirmed on a protein level by immunohistological labeling of tumor tissues. Thirty-nine percent of the analyzed RCC tumors showed partial loss of HLA class I molecules, while 6% of the tumors showed HLA class I total loss. The expression of IP-10, SDF-1 and VEGF-c was also significantly lower in patients with advanced tumor, while the IFN-gamma expression in metastatic RCC was not detectable. Our findings show that primary RCC tumors are characterized by a high expression of HLAhc and a presence of proinflammatory mediators and chemokines. We also observed that disease progression and development of metastasis in RCC are associated with decreased expression of HLAhc, beta2m, IP-10, SDF-1 and IFN-gamma. This microenvironment may suppress the cytotoxic response, creating conditions that favor tumor escape and cancer progression.

Abstract
In preclinical tumor model and in human cancer, tumor antigen specific T lymphocytes play a key role in the control of tumor development. Nevertheless in numerous cases, the infiltrating tumor T cells do not seem to influence the clinical progression of the tumor. A better phenotypic and functional characterization of T cells in close contact with tumor associated with a comprehensive analysis of tumor evasion mechanism to the host response should lead to an optimization of cancer immunotherapy protocols.

Abstract
UNLABELLED Secretory IgA contributes towards the protection of mucosal surfaces against invading microorganisms. OBJECTIVES Quantify secretory IgA titers in the saliva of women with HPV in the oropharynx and/or in the genital area. SUBJECTS AND METHODS Seventy women with clinical genital HPV lesions and 70 women without HPV infection were tested for oral HPV DNA and the levels of total IgA in their saliva. One millilitre of saliva was collected, centrifuged and stored at -80 degrees C for the measurement of secretory IgA by nephelometry technique. A pool of oral pharyngeal cells was collected for HPV identification by polymerase chain reaction. RESULTS Oral HPV PCR was positive in 29 (21%) women (26 women with genital HPV and only 3 women without genital HPV). Titers of secretory IgA were extremely lower in-patients with HPV DNA in the oropharynx when compared to HPV negative women (p<0.0001). Genital HPV and smoking were also associated to low levels of total sIgA in saliva (p<0.01). After multivariable analyses only the presence of HPV in the oral cavity and/or in genital area, but not smoking, was related to low levels of total secretory IgA. CONCLUSION Women with low levels of total secretory IgA could be more susceptible to having their oral mucosa colonized by HPV.

Abstract
PURPOSE Many human tumors lose responsiveness to IFN-gamma, providing a possible mechanism for the tumor to avoid immune recognition and destruction. Here we investigate the importance of tumor responsiveness to IFN-gamma in the successful immunotherapy of TC1 tumors that were immortalized with human papillomavirus proteins E6 and E7. METHODS To investigate the role of IFN-gamma in vivo, we constructed a variant of TC1, TC1.mugR, that is unresponsive to IFN-gamma due to overexpression of a dominant negative IFN-gamma receptor. RESULTS Using recombinant Listeria monocytogenes that express HPV-16 E7 (Lm-LLO-E7) to stimulate an antitumor response, we demonstrate that sensitivity to IFN-gamma is required for therapeutic efficacy in that Lm-LLO-E7 induces regression of TC1 tumors but not TC1.mugR. In addition, we show that tumor sensitivity to IFN-gamma is not required for inhibition of tumor angiogenesis by Lm-LLO-E7 or for trafficking of CD4+ and CD8+ T cells to the tumor. However, it is required for penetration of lymphocytes into the tumor mass in vivo. CONCLUSIONS Our findings identify a role for IFN-gamma in immunity to TC1 tumors and show that loss of tumor responsiveness to IFN-gamma poses a challenge to antigen-based immunotherapy.

Abstract
The aim of this study was to characterize the immune system profile in the uterine cervix of 17 human papillomavirus (HPV)-infected women, compared with 17 whom were coinfected with HIV-1. Five histologically normal cervices in immunocompetent women were used as controls. HPV infection was associated with a marked increase in cells expressing interleukin (IL)-6, interferon gamma (IFN-gamma), and tumor necrosis factor alpha (TNF-alpha). Coinfection by HPV and HIV-1 led to decreased expression of IL-6, TNF-alpha, and IFN-gamma. However, coinfection led to increased numbers of cells expressing IL-4, IL-10, and IL-8. Compared with the histologically normal cervices, increased numbers of macrophages (CD68, RFD7) and T lymphocytes (CD4, CD8) were seen in HPV-infected cervices; coinfection with HIV-1 was associated with a higher number of CD8 cells and lower number of CD68 cells. HPV DNA localized exclusively to the dysplastic squamous cells, whereas HIV-1 RNA was detected mainly in CD68-positive stromal cells. In conclusion, this study shows differential expression of various cytokines and classes of inflammatory cells, relative to HIV-1 infection and HPV coinfection, which may relate to the risk of transmission of HIV-1 and increased risk of cervical cancer in these women.

Abstract
Beyond human papillomavirus (HPV) infection, host genetic factors may contribute to cervical carcinogenesis. This study aims to test the hypothesis that CA-dinucleotide repeat polymorphism in the first intron of the interferon-gamma (IFN-gamma) gene is associated with HPV-initiated cervical carcinogenesis. A hospital-based case-control study including patients with low-grade squamous intraepithelial lesions (LSILs; n = 93), high-grade squamous intraepithelial lesions (HSILs; n = 123) and invasive carcinomas (n = 153) of the uterine cervix, as well as 1:1 age-matched controls, was conducted. The IFN-gamma genotype was determined by PCR and capillary electrophoresis with internal standards. HPV genotype was determined by consensus PCR and reverse line blot hybridization. Genotypes containing the 12 or 14 allele (12 or 14 CA repeats) were significantly more common in patients with HSILs than in controls (46% vs. 22%; OR = 3.0; 95% CI = 1.7-5.2; p < 0.0001). In contrast, genotypes containing 13 and 18 were significantly more common in controls than in patients with HSILs (76% vs. 53%; OR = 0.3; 95% CI = 0.2-0.6; p = 0.0001) or squamous cell carcinomas (74% vs. 63%; OR = 0.6; 95% CI = 0.4-1.0; p = 0.037). The frequency of the 12 and 14 genotypes increased significantly in accordance with the severity of cervical carcinogenesis (p(test for trend) = 0.0002), whereas the 13 and 18 genotypes showed the opposite trend (p(test for trend) = 0.007). Comparing IFN-gamma genotype and HPV status, 18-containing genotypes were more frequently found in HPV(+) LSILs, and 12-containing genotypes were less frequently found in HPV(+) HSILs. Compared with non-13 genotypes, 13 genotype HSILs were more frequently infected with HPV58 (70% vs. 45%) and less frequently infected with HPV18 (0% vs. 16%; p= 0.007). Genetic polymorphism of the IFN-gamma gene is associated with individual susceptibility to cervical carcinogenesis. This polymorphism correlates with HPV infection in a disease- and type-specific manner.

Abstract
The innate immune responses at mucosal surfaces of the lower female genital tract play a central role in preventing the establishment of infection. Variability in the genes regulating innate immune recognition or response to infectious microorganisms could explain interindividual differences in susceptibility to infection and severity of infectious disorders. Of the numerous genetic variations identified within immunoregulatory genes, only a few have so far been studied in relation to infectious disorders of the lower female genital tract. Although these studies broaden our understanding of the genetic influence on mucosal innate immunity and microbiologic outcome, they also highlight the complexity of links between genotypical and phenotypical features, ie, the influence of a single genetic marker on the phenotype is at best moderate and is not constant in every ethnic/racial group. Such inconsistency is primarily attributed to gene-to-gene interactions and demographic genetic variability. Large case-control studies evaluating multiple genetic markers simultaneously in well-defined subgroups will characterize patients more accurately and pave the way to personalized medicine.

Abstract
PROBLEM Granulocyte colony-stimulating factor (G-CSF) is often administered to patients with chemotherapy-induced leukocytopenia. However, adequate attention has not been paid to its effects on cancer immunology. Reported by us and others, G-CSF often induces immunosuppression and down-regulation of response T helper (Th)2 directed immune reaction both in vivo and in vitro. In this study, we analyzed the effects of G-CSF on interferon (IFN)-gamma production and autologous tumor killing (ATK) activities of peripheral blood mononuclear cells (PBMCs). METHODS OF STUDY In order to evaluate the cytokine-induced activation of peripheral T and natural killer (NK) cells, we analyzed IFN-gamma production by interleukin (IL)-2- and IL-12-stimulated PBMCs, using the ELISPOT assay. Specific killing of autologous tumor cells was evaluated by lactate dehydrogenase (LDH) release assay. RESULTS The PBMC collected from both cancer-bearing patients and healthy subjects showed IL-2- and/or IL-12-induced IFN-gamma production. The frequency of IFN-gamma producing cells was significantly higher in the normal subjects compared with the patients with advanced ovarian carcinoma. The ATK activity was also enhanced in IL-2- and/or IL-12-stimulated PBMCs of patients with ovarian carcinoma. G-CSF almost completely abolished IFN-gamma production and ATK activity of PBMC stimulated with IL-2 and/or IL-12. CONCLUSIONS The G-CSF appears to be a suppressor of antitumor immunity. Routine administration of G-CSF to cancer patients may not be recommended, except for febrile neutropenia.

Abstract
OBJECTIVES Persistent high-risk HPV infection of the uterine cervix is associated with CIN and cervical carcinoma. Women with a reduced pro-inflammatory response to HPV are likely to be susceptible to viral persistence, and therefore, potentially more vulnerable to cervical neoplasia. In this study, we investigate whether nucleotide sequence polymorphisms in the TNFalpha (TNFSF2) gene (which can modify gene transcription up to 9-fold) might influence susceptibility to, or evolution of, CIN. METHODS Induced heteroduplex analysis was used to identify polymorphisms at positions TNFalpha -308 and -238 in women with normal cervical cytology and with cervical disease. Patients with low-grade disease were HPV typed using general primer GP5+/6+ PCR/EIA and reverse line blotting, and were reassessed for disease status at 6 and 24 months. RESULTS CIN patients as a group had a significantly higher frequency of TNFalpha -308 low-secretor genotypes (GG) compared to controls, and this effect was most pronounced in the CIN1 group (P = 0.01 and P = 0.004, respectively). TNFalpha polymorphism frequencies at position -238 were similar for patients and controls. Neither polymorphism was associated with the presence of HPV infection at recruitment or disease outcome at 6 or 24 months. CONCLUSIONS These findings support the hypothesis that susceptibility to CIN is influenced by TNFalpha -308 polymorphism.

Abstract
Murine models have shown that IL-18 has antiangiogenic and antitumor effects, but little is known about IL-18 production in human tumors. We investigated IL-18 expression in clinically localized prostate cancers by immunohistochemistry and showed that 75% of the prostate cancers studied (27/36 cases) presented with tumor cells producing IL-18. Prostate tumor cell lines PC-3, DU 145 and LNCaP synthesized the immature form of IL-18 (p24). IFN-gamma produced in prostate cancers induced caspase-1 mRNA and IL-18 secretion of tumor cell lines, which was inhibited by the cell-permeable Tyr-Val-Ala-Asp-aldehyde caspase-1 inhibitor (YVAD-CHO). Interestingly, IFN-alpha also induced IL-18 secretion of the poorly differentiated cell line PC-3. PC-3 and DU 145, but not the well-differentiated cell line LNCaP, expressed IL-18R alpha (IL-1Rrp) protein and transcripts for IL-18R beta (AcPL). Exogenous IL-18 increased mitochondrial activity of both cell lines evaluated by the tetrazolium (MTT) assay but did not influence their proliferation. This indicated that prostate tumor cells could secrete IL-18 in response to IFN-gamma in the tumor microenvironment and that IL-18 could act as a autocrine/paracrine factor for the tumor. In the cohort of patients studied, IL-18 expression in prostate cancers (with up to 10% of tumor cells stained) was associated with a favorable outcome and equally predictive as pathologic stage on multivariate analysis (log rank test, p = 0.02). Tumor IL-18 production is a novel physiopathologic feature of prostate cancer and appears to be a favorable event in the course of the disease. Modulation of IL-18 production by interferons could have a beneficial clinical effect, which deserves further investigation.

Abstract
We have examined the induction of anti-tumour immunity in a murine model using a gene vaccine approach to deliver a well defined tumour antigen. The vaccines expressed the human papilloma virus type 16 (HPV 16) E7 oncoprotein, and protection was measured against HPV 16-expressing C3R tumour cell line in vivo. In control mice injected with saline, C3R cells initially formed tumours but then regressed completely. As expected, animals injected with a peptide that represents the D(b)-presented CTL epitope from E7 (RAHYNIVTF) were completely protected from tumour growth. Contrary to expectation, however, we consistently saw enhanced tumour growth, delayed regression, or tumour outgrowth in mice vaccinated with two different E7-expressing DNA vaccines. We found no evidence for loss of D(b) or K(b) class I MHC molecules from C3R cells recovered from outgrown tumours, and fluorescent MHC/peptide tetramer staining revealed E7 gene vaccination did not delete RAHYNIVTF-specific CD8(+) T cells. However, we did observe an effect on cytokine production. Splenocytes from E7 gene vaccinated animals responded to re-stimulation in vitro with C3R cells by producing IL-4 but background levels of IFN-gamma. We also observed that cytokine production and E7 peptide-specific CTL were only detectable in vaccinated animals after C3R challenge, but not after DNA priming alone. We conclude that 'prime-boosting' is necessary to observe tumour-specific T cell responses with the gene vaccine approach, but that boosting with tumour cells causes skewing of the primed cells in a T2 direction that is incompatible with protective anti-tumour immunity.

Abstract
OBJECTIVE To evaluate the potential of autologous dendritic cells (DC) pulsed with HPV16 and HPV18 E7 oncoprotein in restoring tumor-specific cytotoxicity in populations of tumor infiltrating lymphocytes (TIL) for adoptive immunotherapy of cervical cancer patients. METHODS Full-length E7-pulsed DC-stimulated CD8(+) T cells derived from peripheral blood (PBL) and from tumor tissues (TIL) were tested and compared for their ability to induce a HLA class-I-restricted cytotoxic T lymphocyte (CTL) response against autologous tumor cells. In addition, in order to correlate cytotoxic activity by CTL with a particular lymphoid subset, analysis of surface antigens and intracellular CD3 zeta chain and two-color flow cytometric analysis of intracellular cytokine expression (IFN-gamma vs IL-4) at the single cell level were performed. RESULTS DC stimulation induced powerful cytotoxicity against autologous tumor target cells by TIL-derived CD8(+) T cells from all three cervical cancer patients, while autologous Epstein-Barr virus-transformed lymphoblastoid cell lines were not lysed. Killing of autologous tumor cells was higher by CD8(+) T cells from TIL compared to PBL (P > 0.01) and was more strongly inhibited by anti-HLA class I MAb (P > 0.05). Phenotypically, all CTL populations were CD3(+)/CD8(+), with higher levels of CD56 expression by TIL-derived CTL. Finally, although a marked Type 1 cytokine bias (i.e., IFN-gamma(high)/IL-4(low)) was observable in both PBL- and TIL-derived DC-stimulated CD8(+) T cell populations, TIL-derived CD8(+) T cells showed a higher percentage of IFN-gamma-positive cells compared to PBL. CONCLUSIONS Full-length E7-pulsed DC can consistently restore strong CD8(+) CTL responses against autologous HPV16- and HPV18-infected cervical cancer cells. DC-stimulated TIL may represent a superior source of tumor-specific CTL compared to PBL for adoptive T cell immunotherapy of patients harboring metastatic or recurrent cervical cancer refractory to standard treatment modalities.

Abstract
OBJECTIVE To investigate in vitro natural killer (NK) cell activity and expression of signal-transducing zeta chains in patients with cervical cancer. PATIENTS AND METHODS Experiments were performed with frozen lymphocytes from patients at all disease stages and from healthy controls. Thawed NK were activated by overnight incubation in interferon-gamma (IFN-gamma); activity against two target cell lines was assessed by 4-h (51)Cr release assay. Targets chosen were K562, an erythroleukemic cell line, and a cervical carcinoma cell line designated 808. T and NK cell zeta chain expression was measured by flow cytometry. RESULTS Patients' NK were found to be as cytotoxic as those of normal controls against cell lines K562 and 808. Patient T and NK cells did not show significant down-regulation of the zeta chain. CONCLUSIONS We have found no evidence to suggest that loss of zeta chains is a mechanism for immunocompromise in patients with cervical carcinoma. IFN-recoverable patient NK activity is not reduced compared to matched controls. This may be clinically relevant since NK are active against cells exhibiting class I human leukocyte antigen (HLA) down-regulation and many cervical cancers show loss of HLA.

Abstract
Type 1 cytokines, such as interferon gamma (IFNgamma) and interleukin-2 (IL-2), increase T cell-mediated immune responses and are considered to be beneficial for antitumour immunity. Type 2 cytokines, such as IL-4, IL-5, and IL-10, inhibit Type 1 responses and promote humoral responses. We have previously reported an association between low intratumoral IFNgamma mRNA levels and poor clinical outcome in patients with invasive cervical carcinoma. In this study, by using quantitative polymerase chain reaction (PCR), we identified a group of cervical carcinoma patients with undetectable intratumoral T cell-derived cytokine mRNAs, as IFNgamma, IL-4 and IL-17 expression could not be detected in 5, 25 and 8 of the 52 biopsies analysed, respectively. Global downregulation of Type 1 and Type 2 cytokines was observed in a subgroup of patients who more frequently presented advanced stage tumours. Biopsies of patients with no IFNgamma gene expression did not appear to be less infiltrated by T cells than control biopsies with measurable IFNgamma gene expression. These results clearly demonstrate that, in some clinical situations, the decrease in intratumoral Type 1 cytokines is not associated with a Type 2 polarisation, but rather reflects global deactivation of T cells at the tumour site. These data provide support for immunotherapy protocols designed to reverse the anergic state of T cells in cancer.

Abstract
BACKGROUND The streptococcal agent OK-432 has been used for immunotherapy of head and neck cancer, among other malignancies, but its mechanism of action is unknown. Because the Toll-like receptor 4 (TLR4)/MD-2 complex is important in enabling the mammalian immune system to recognize bacterial components, we investigated whether expression of the TLR4 and MD-2 genes is associated with OK-432-induced anticancer immunity. METHODS Peripheral blood mononuclear cells (PBMCs) from 28 patients with head and neck cancer were analyzed for TLR4 and MD-2 mRNA expression by reverse transcription-polymerase chain reaction (RT-PCR) analysis. PBMCs were treated in vitro with OK-432 or with OK-PSA (a lipoteichoic-acid-related molecule that is an active component of OK-432), and interferon-gamma (IFN-gamma) mRNA expression, an immune response measure, was analyzed by RT-PCR. Patient sera collected 24 hours after OK-432 administration were examined for IFN-gamma protein using an enzyme-linked immunosorbent assay. Lewis lung carcinoma-bearing wild-type C57BL/6 and TLR4-deficient mice (four mice per group) received intraperitoneal injections of OK-432, and tumor volumes and sera IFN-gamma levels were measured over time. All statistical tests were two-sided. RESULTS Twenty patients expressed both TLR4 and MD-2. Expression of TLR4 and MD-2 genes was associated with the in vivo IFN-gamma induction in 19 patients administered OK-432 (Fisher's exact test P<.001). Although both OK-432 and OK-PSA induced IFN-gamma expression from PBMCs in vitro, expression of TLR4 and MD-2 was associated only with IFN-gamma expression induced by OK-PSA (P<.001). In vivo intraperitoneal administration of OK-432 resulted in an increase of IFN-gamma in sera from wild-type mice but not in sera from TLR4-deficient mice. Tumors in wild-type mice treated with OK-432 were statistically significantly smaller than those in mice treated with saline (P =.007). By contrast, in TLR4-deficient mice, there was no difference in tumor volume between the two treatment groups. CONCLUSIONS TLR4 and MD-2 may mediate OK-432-induced anticancer immunity.

Abstract
PURPOSE To analyze prospectively the effects of blood transfusion administered during radiotherapy (RT) on the immune function of patients with locally advanced cervical cancer. METHODS AND MATERIALS In a total of 15 patients, 7 transfused and 8 untransfused, lymphocyte populations, including CD3+, CD4+, and CD8+ T-cell subsets, B cells (CD19+), and natural killer (NK) cells (CD56+, CD16+, CD3-) were studied before (i.e., time 0), during (i.e., times 1 and 2), and after (i.e., time 3) therapy. Expression of the early (CD25) and late (HLA-DR) activation markers on CD3+ T cells, the intracellular levels of perforin in CD8+ and CD56+ cells, and interferon (IFN)-gamma, interleukin (IL)-2, and IL-4 in CD4+ and CD8+ T cells were also measured. NK cell cytotoxicity against the NK-sensitive target K-562 cells and CD8+ T-cell-directed cytotoxicity against OKT3 hybridoma cells were also assessed. Finally, the plasma levels of the immunoregulatory cytokine IL-10 were analyzed by enzyme-linked immunosorbent assay. RESULTS The mean absolute number of all lymphocyte subsets compared with pretreatment levels decreased significantly during RT of both transfused and untransfused patients (p >0.001), with no detectable differences between the two groups in terms of total lymphocytes or relative numbers of CD3+ and CD4+ T cells, CD56+ NK cells, or CD19+ B cells. In contrast, concomitant with an inversion of the CD4/CD8 ratio, a significant increase in the number of CD8+ T cells at time 2 and CD3+ T cells, CD8+ T cells, and NK cells at time 3 was found in the transfused patients compared with the untransfused group. The percentages of CD25+/CD3+ T cells and HLA-DR+/CD3+ T cells increased during RT of the untransfused patients, but CD3+ T cells showed decreased CD25 expression and increased HLA-DR expression in the transfused group. An increase of CD8+ IFN-gamma+ T cells with a concomitant decrease in CD8+ IL-2+ T cells was found in the transfused vs. untransfused group, and no differences were noted in the percentage of CD4+ IFN-gamma+ T cells and CD4+ IL-2+ T cells. The proportion of perforin-positive CD8+ and CD56+ cells was higher in the transfused group than in the untransfused group. However, CD56+ cells and CD8+ T cells from the transfused patients showed markedly diminished cytotoxic function. Finally, IL-10 was detected only in the plasma of the transfused patients. CONCLUSION Blood transfusion during primary RT for cervical cancer profoundly alters the magnitude and characteristics of radiation-induced immunosuppression. Elevated serum IL-10 in transfused patients may play a role in the disregulation of lymphocyte function, in particular, the depression of NK- and T-cell cytotoxicity. Investigation of alternatives to blood transfusion during RT that do not diminish host immunity is warranted.

Abstract
Interferon (IFN)-gamma and Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) enhance tumor immunogenicity. The authors assessed tolerability and effectiveness of a combination therapy of these recombinant human (rh) cytokines in patients with inoperable hepatocellular carcinoma (HCC). In a monocentric, open, nonrandomized pilot study, rhGM-CSF (5 microg/kg qd, Monday and Tuesday) and rhIFN-gamma (100 microg qd, Wednesday and Thursday) were subcutaneously administered in 9-week cycles. Primary objective was survival, as secondary outcomes volumetric changes of tumor mass and biologic parameters reflecting systemic immunologic or local tumor responses were measured. Only patients with complete response (CR), partial response (PR), or stable disease (SD) proceeded to new treatment cycles. Fifteen patients (median 63 years, range 46-74 years, all men) were enrolled. Survival after the first cycle was 80% with SD in 9 of 15 patients (60%). PR was detected in one patient after the second cycle. Two patients finished five treatment cycles. Overall survival at 26 and 52 weeks was 40% and 20%, respectively. Median survival in patients with inducible HLA-DR on hepatoma cells (40%) was increased (42 weeks, 27-100) as compared with HLA-DR negative cases (60%; 13 weeks, 8-23; p < 0.0001), and a control group (p = 0.01). Parameters reflecting systemic immunomodulatory activities were not associated with clinical outcome. In 13 of 15 patients (87%), adverse events were reported, all less than grade 2 and none requiring therapy discontinuation. Immunotherapeutic approaches hold promise to prolong survival in selected patients with advanced HCC who respond by enhanced tumor immunogenicity.

Abstract
To study the prevalence of the oncogenes c-myc, IFN-alpha; c-erbB2; H-ras codon 12, 13, and 61; c-fos; and E6/E7 oncogenes of human papillomavirus (HPV) 16 in patients with invasive carcinoma of the cervix and their prognostic significance, genomic DNA and RNA were isolated from tissues of 275 patients in Singapore with nonmetastatic cervical cancer and 32 patients with normal cervix. The levels of expression of the various oncogenes were quantified by PCR using the respective primers. When the PCR data on the DNA were analyzed by the log-rank test, IFN gamma (P = 0.02) and H-ras codon 12 and 13 (P = 0.02) were found to be prognostic. In the multivariate analysis, a statistically significant trend for increasing risk with higher quartiles was found for c-myc (P = 0.007) and c-erbB2 (P = 0.03). After adjusting for age and stage, a correlation appears between the amplification of the oncogenes c-myc, c-erbB2, and H-ras codon 12, 13, and 61 and the development of recurrent cervical cancer. Further adjustment to include the parameters of treatment and histology type did not change the outcome of the correlation observed.

Abstract
AT helper 1 (Th1) immune response is considered more effective than T helper 2 (Th2) for anti-tumor immunity, but either response could potentially stimulate tumor cell growth in lymphomas. Moreover, both IL-4 and IL-2/IL-12 are used in experimental treatment models for non-Hodgkin's lymphoma (NHL) despite their differing ability to elicit Th2 or Th1 responses, respectively. Here, we investigate which T helper cytokines (Th1 or Th2) predominate in B cell NHL tissue and determine whether cytokine expression correlates with tumor cell growth, cell death, and survival in a series of 44 NHL patients. Overall, we observed both Th1 and Th2 cytokine expression at the mRNA level, detecting high levels of IFN-gamma, IL6 and IL-10 expression in the majority of tumors. Transcripts for the IL-12 subunits p35 (38 of 38) and p 40 (23 of 38) were frequently detected in NHL tissue, and high p40 levels were common in patients with a good prognosis. Furthermore, high IL-4 levels correlated with greater survival duration (P < 0.0024) but nor overall survival. Cytokine expression of IL-2, IFNgamma and IL-4 was significantly reduced in the high grade tumor group. Interestingly, there was a strong correlation between high IL-4 levels and reduced levels of apoptosis (P < 0.006) or proliferation (P < 0.0001), which has also been reported in leukemic models. This has important implications for the success of IL-4 as a treatment for low and high grade tumors.

Abstract
Because oncogenic DNA viruses establish persistent infections in humans, continuous immunosurveillance for neoplastic cells is required to prevent virus-induced tumors. Antigen-specific CD8+ T lymphocytes are critical in vivo effectors for eliminating virus-infected and virus-transformed cells. Investigation into the induction, regulation, and maintenance of CD8+ T cells specific for these viruses is hindered by the lack of tractable animal models that mimic natural infection. Resistance to tumors induced by polyoma virus, a persistent natural mouse DNA virus, is mediated by polyoma-specific CD8+ T cells. Mice susceptible to polyoma virus tumorigenesis mount a smaller, albeit still considerable, expansion of anti-polyoma CD8+ T cells; importantly, these antiviral CD8+ T cells lack cytotoxic activity while retaining the phenotype of cytotoxic T lymphocyte (CTL) effectors. In this review, we will discuss potential in vivo mechanisms that regulate the functional competence of anti-polyoma CD8+ T cells, particularly in the context of chronic antigenic stimulation provided by persistent viral infections and tumors.

Abstract
The peritoneal membrane, formed by a single layer of mesothelial cells, lines the largest cavity of the human body. Anatomic structures of the peritoneal cavity, along with resident leukocyte populations, play an important role in the defense against microorganisms invading by breaching the gut integrity or ascending through the female genital tract. Local immune mechanisms in the peritoneal cavity are also important in patients undergoing peritoneal dialysis and in women with endometriosis. There is now extensive evidence demonstrating the significance of peritoneal immune mechanisms in the control of metastatic spread. Leukocytes belonging to both the innate and adaptive immune systems are present in the peritoneal cavity of normal subjects as well as in patients with intra-abdominal cancer. There is now increased understanding of the mechanisms that not only allow the tumor cells to escape the detection and destruction by the host immune system, but also to use the inflammatory mechanisms to promote tumor growth and spread inside the peritoneal cavity. Malignant ascites represents a model for the study of the interaction between tumor cells and the host immune system as well for the analysis of the tumor microenviroment. The peritoneal immune system may be stimulated by intraperitoneal administration of biologic agents. This peritoneal immunotherapy may be used for palliation of malignant ascites, or as a consolidation strategy in patients with minimal residual disease.
