TBCRC 039: a phase II study of preoperative ruxolitinib with or without paclitaxel for triple-negative inflammatory breast cancer. Breast Cancer Res 2024; 26:20. [PMID: 38297352 PMCID: PMC10829369 DOI: 10.1186/s13058-024-01774-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 01/18/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND Patients with inflammatory breast cancer (IBC) have overall poor clinical outcomes, with triple-negative IBC (TN-IBC) being associated with the worst survival, warranting the investigation of novel therapies. Preclinical studies implied that ruxolitinib (RUX), a JAK1/2 inhibitor, may be an effective therapy for TN-IBC. METHODS We conducted a randomized phase II study with nested window-of-opportunity in TN-IBC. Treatment-naïve patients received a 7-day run-in of RUX alone or RUX plus paclitaxel (PAC). After the run-in, those who received RUX alone proceeded to neoadjuvant therapy with either RUX + PAC or PAC alone for 12 weeks; those who had received RUX + PAC continued treatment for 12 weeks. All patients subsequently received 4 cycles of doxorubicin plus cyclophosphamide prior to surgery. Research tumor biopsies were performed at baseline (pre-run-in) and after run-in therapy. Tumors were evaluated for phosphorylated STAT3 (pSTAT3) by immunostaining, and a subset was also analyzed by RNA-seq. The primary endpoint was the percent of pSTAT3-positive pre-run-in tumors that became pSTAT3-negative. Secondary endpoints included pathologic complete response (pCR). RESULTS Overall, 23 patients were enrolled, of whom 21 completed preoperative therapy. Two patients achieved pCR (8.7%). pSTAT3 and IL-6/JAK/STAT3 signaling decreased in post-run-in biopsies of RUX-treated samples, while sustained treatment with RUX + PAC upregulated IL-6/JAK/STAT3 signaling compared to RUX alone. Both treatments decreased GZMB+ T cells implying immune suppression. RUX alone effectively inhibited JAK/STAT3 signaling but its combination with PAC led to incomplete inhibition. The immune suppressive effects of RUX alone and in combination may negate its growth inhibitory effects on cancer cells. CONCLUSION In summary, the use of RUX in TN-IBC was associated with a decrease in pSTAT3 levels despite lack of clinical benefit. Cancer cell-specific-targeting of JAK2/STAT3 or combinations with immunotherapy may be required for further evaluation of JAK2/STAT3 signaling as a cancer therapeutic target. TRIAL REGISTRATION www.

Abstract
Signal Transducer and Activator of Transcription 3 (STAT3) plays a significant role in diverse physiologic processes, including cell proliferation, differentiation, angiogenesis, and survival. STAT3 activation via phosphorylation of tyrosine and serine residues is a complex and tightly regulated process initiated by upstream signaling pathways with ligand binding to receptor and non-receptor-linked kinases. Through downstream deregulation of target genes, aberrations in STAT3 activation are implicated in tumorigenesis, metastasis, and recurrence in multiple cancers. While there have been extensive efforts to develop direct and indirect STAT3 inhibitors using novel drugs as a therapeutic strategy, direct clinical application remains in evolution. In this review, we outline the mechanisms of STAT3 activation, the resulting downstream effects in physiologic and malignant settings, and therapeutic strategies for targeting STAT3. We also summarize the pre-clinical and clinical evidence of novel drug therapies targeting STAT3 and discuss the challenges of establishing their therapeutic efficacy in the current clinical landscape.

An observational study of the impact of immediate breast reconstruction on perioperative inflammatory cytokines. Surg Today 2023; 53:1305-1316.

Abstract
PURPOSE Perioperative inflammatory cytokines may be related to cancer proliferation, although few studies have investigated this issue in patients undergoing breast reconstruction surgery. METHODS We conducted a prospective study of patients scheduled for mastectomy only, mastectomy plus deep inferior epigastric perforator flap reconstruction (DIEP), or mastectomy plus tissue expander reconstruction (TE), with or without axial dissection (Ax), for primary breast cancer. Blood samples were collected for analysis of serum IL-6 and VEGF preoperatively, then within 24 h postoperatively (POD 1), and 4-6 days postoperatively (POD 4-6). We investigated the difference in serum cytokine levels over time for each surgical procedure and the difference in serum cytokine levels among the procedures at the three measurement time points. RESULTS There were 120 patients included in the final analysis. Serum IL-6 was significantly higher than the preoperative level on POD 1 in patients who underwent mastectomy only, DIEP, or TE and Ax (+), with higher values persisting on POD 4-6 except in those who underwent DIEP. IL-6 was significantly higher after DIEP than after mastectomy only on POD 1, but no differences were observed at POD 4-6. VEGF did not differ significantly among the surgical procedures at any time. CONCLUSIONS The increase in IL-6 was short term and immediate breast reconstruction is considered a safe procedure.

Abstract
Having infected by Helicobacter pylori, the infection often leads to gastritis, gastric ulcer, or even gastric cancer. The disease is typically treated with antibiotics as they used to effectively inhibit or kill H. pylori, thus reducing the incidence of gastric adenoma and cancer to significant extent. H. pylori, however, has developed drug resistance to many clinically used antibiotics over the years, highlighting the crisis of antibiotic failure during the H. pylori treatment. We report here that the fucoidan from Sargassum hemiphyllum can significantly reduce the infection of H. pylori without developing to drug resistance. Fucoidan appears to be a strong anti-inflammation agent as manifested by the RAW264.7 cell model examination. Fucoidan can prohibit H. pylori adhesion to host cells, thereby reducing the infection rate by 60%, especially in post treatment in the AGS cell model assay. Mechanistically, fucoidan intervenes the adhesion of BabA and AlpA of H. pylori significantly lowering the total count of H. pylori and the level of IL-6 and TNF-α in vivo. These results all converge on the same fact that fucoidan is an effective agent in a position to protect the stomach from the H. pylori infection by reducing both the total count and induced inflammation.

Abstract
IL6-like cytokines are a family of regulators with a complex, pleiotropic role in both the healthy organism, where they regulate immunity and homeostasis, and in different diseases, including cancer. Here we summarise how these cytokines exert their effect through the shared signal transducer IL6ST (gp130) and we review the extensive evidence on the role that different members of this family play in breast cancer. Additionally, we discuss how the different cytokines, their related receptors and downstream effectors, as well as specific polymorphisms in these molecules, can serve as predictive or prognostic biomarkers with the potential for clinical application in breast cancer. Lastly, we also discuss how our increasing understanding of this complex signalling axis presents promising opportunities for the development or repurposing of therapeutic strategies against cancer and, specifically, breast neoplasms.

Abstract
Novel biomarkers are needed to continue to improve breast cancer clinical management and outcome. IL6-like cytokines, whose pleiotropic functions include roles in many hallmarks of malignancy, rely on the signal transducer IL6ST (gp130) for all their signalling. To date, 10 separate independent studies based on the analysis of clinical breast cancer samples have identified IL6ST as a predictor. Consistent findings suggest that IL6ST is a positive prognostic factor and is associated with ER status. Interestingly, these studies include 4 multigene signatures (EndoPredict, EER4, IRSN-23 and 42GC) that incorporate IL6ST to predict risk of recurrence or outcome from endocrine or chemotherapy. Here we review the existing evidence on the promising predictive and prognostic value of IL6ST. We also discuss how this potential could be further translated into clinical practice beyond the EndoPredict tool, which is already available in the clinic. The most promising route to further exploit IL6ST's promising predicting power will likely be through additional hybrid multifactor signatures that allow for more robust stratification of ER+ breast tumours into discrete groups with distinct outcomes, thus enabling greater refinement of the treatment-selection process.

Abstract
BACKGROUND Adipocytokines, adipose tissue-derived proteins, were demonstrated to be involved in the pathogenesis of breast cancer. We assessed the mRNA expression of resistin, tumor necrosis factor-alpha (TNF-α), interleukins 6 and 8 (IL-6, and IL-8), and estrogen receptor alpha (ER-α) in peripheral blood mononuclear cells (PBMCs) of women with and without breast cancer. METHODS The PBMCs were isolated from the whole blood of 32 women with breast cancer and 18 women without breast cancer using density gradient centrifugation. The mRNA expression of the target genes was measured by reverse-transcription polymerase chain reaction (RT-PCR). Body mass index was calculated, additionally, clinicopathological characteristics of the breast cancer patients were determined by histopathological examination. RESULTS The mRNA expression of resistin (3.5-fold) and IL-6 (15-fold) in PBMCs of breast cancer patients significantly increased in comparison to healthy controls. Resistin expression was significantly associated with inflammatory markers including TNF-α, IL-6, IL-8, but not with anthropometric indices. Logistic regression analysis revealed the studied adipokines were not associated with breast cancer. Based on the ROC curve analysis the diagnostic performance of IL-6 was significant (0.825, 95% CI: 0.549-0.94, p = 0.030), thus, it might be considered as a breast cancer biomarker that reflecting an early and inflammatory stage of the disease. DISCUSSION Breast cancer is not associated with increased expression of inflammatory cytokines in PBMCs. Our results suggested that a PBMC-based gene expression test may be developed to detect breast cancer early.

Abstract
Interleukin-6 (IL-6) is a pleiotropic cytokine that activates a classic signalling pathway upon binding to its membrane-bound receptor (IL-6R). Alternatively, IL-6 may 'trans-signal' in a manner that is facilitated by its binding to a soluble derivative of the IL-6 receptor (sIL-6R). Resultant signal transduction is, respectively, driven by the association of IL-6/IL-6R or IL-6/sIL-6R complex with the membrane-associated signal transducer, gp130 (Glycoprotein 130). Distinct JAK (Janus tyrosine kinase)/STAT (signal transducers and activators of transcription) and other signalling pathways are activated as a consequence. Of translational relevance, overexpression of IL-6 has been documented in several neoplastic disorders, including but not limited to colorectal, ovarian and breast cancer and several haematological malignancies. This review attempts to summarise our current understanding of the role of IL-6 in cancer development. In short, these studies have shown important roles for IL-6 signalling in tumour cell growth and survival, angiogenesis, immunomodulation of the tumour microenvironment, stromal cell activation, and ultimate disease progression. Given this background, we also consider the potential for therapeutic targeting of this system in cancer.

Interleukin-6 receptor inhibitor suppresses bone metastases in a breast cancer cell line. Breast Cancer 2018; 25:566-574. [PMID: 29557068 DOI: 10.1007/s12282-018-0853-9] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Accepted: 03/15/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Interleukin-6 (IL-6) is a potent inflammatory cytokine that appears to play a key role in cancer growth and metastasis. In the present study, the effects of IL-6 receptor (IL-6R) on breast cancer aggressiveness and bone metastases were investigated. METHODS MDA-MB-231 (MDA-231) cells were treated in the presence or absence of anti-human IL-6 receptor (IL-6R) monoclonal antibody and examined with respect to cell survival. The expressions of signal transducer and activator of transcription 3 (Stat3), vascular endothelial growth factor (VEGF), and receptor activator of NF-κB (RANK) were analyzed by SDS-PAGE and immunoblotting. MDA-231 cells were injected into the left ventricle of mice, and then anti-human IL-6R monoclonal antibody or saline was administered intraperitoneally for 28 days. After 28 days, the incidence of bone metastases was evaluated in the hind limbs by radiography and histology. RESULTS Anti-human IL-6R monoclonal antibody reduced bone metastases in an animal model injected with MDA-231 cells on radiological and histomorphometric analyses. The mechanism of bone metastasis inhibition involved inhibited cell proliferation and decreased expressions of phospho-Stat3, VEGF, and RANK in MDA-231 cells. CONCLUSIONS The results of the present study suggest that inhibition of IL-6 signaling may become a preventive therapeutic option for breast cancer and bone metastases.

Abstract
SERS-active nanostructures incorporated into a microfluidic device have been developed for rapid and multiplex monitoring of selected Type 1 cytokine (interleukins: IL-6, IL-8, IL-18) levels in blood plasma. Multiple analyses have been performed by using nanoparticles, each coated with different Raman reporter molecules: 5,5′-dithio-bis(2-nitro-benzoic acid) (DTNB), fuchsin (FC), and p-mercatpobenzoic acid (p-MBA) and with specific antibodies. The multivariate statistical method, principal component analysis (PCA), was applied for segregation of three different antigen-antibody complexes encoded by three Raman reporters (FC, p-MBA, and DTNB) during simultaneous multiplexed detection approach. To the best of our knowledge, we have also presented, for the first time, a possibility for multiplexed quantification of three interleukins: IL-6, IL-8, and IL-18 in blood plasma samples using SERS technique. Our method improves the detection limit in comparison to standard ELISA methods. The low detection limits were estimated to be 2.3 pg·ml−1, 6.5 pg·ml−1, and 4.2 pg·ml−1 in a parallel approach, and 3.8 pg·ml−1, 7.5 pg·ml−1, and 5.2 pg·ml−1 in a simultaneous multiplexed method for IL-6, IL-8, and IL-18, respectively. This demonstrated the sensitivity and reproducibility desirable for analytical examinations.

Abstract
An ultrasensitive surface-enhanced Raman scattering (SERS) immunoassay based on diatom biosilica with integrated gold nanoparticles (AuNPs) for the detection of interleukin 8 (IL-8) in blood plasma has been developed. The SERS sensing originates from unique features of the diatom frustules, which are capable of enhancing the localized surface-plasmon resonance of metal nanostructures. The SERS immune tags ware fabricated by functionalizing 70-nm Au nanoparticles with DTNB (i.e., 5,5′-dithiobis(2-nitrobenzoic acid)), which acted as a Raman reporter molecule, as well as the specific antibodies. These DTNB-labeled immune-AuNPs can form a sandwich structure with IL-8 antigens (infection marker) and the antibodies immobilized on the biosilica material. Our method showed an improved IL-8 detection limit in comparison to standard ELISA methods. The current detection limit for IL-8 using a conventional ELISA test is about 15.6 pg mL−1. The lower detection limit for IL-8 in blood plasma was estimated to be 6.2 pg mL−1. To the best of our knowledge, this is the first report on the recognition of IL-8 in human samples using a SERS-based method. This method clearly possesses high sensitivity to clinically relevant interleukin concentrations in body fluids. The average relative standard deviation of this method is less than 8%, which is sufficient for analytical analysis and comparable to those of classical ELISA methods. This SERS immunoassay also exhibits high biological specificity for the detection of IL-8 antigens. The established SERS immunoassay offers a valuable platform for the ultrasensitive and highly specific detection of immune biomarkers in a clinical setting for medical diagnostics.

Serum sonic hedgehog (SHH) and interleukin-(IL-6) as dual prognostic biomarkers in progressive metastatic breast cancer. Sci Rep 2017; 7:1796. [PMID: 28496132 PMCID: PMC5431756 DOI: 10.1038/s41598-017-01268-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Accepted: 03/28/2017] [Indexed: 12/25/2022] Open
Abstract
Serum from one hundred and ten breast cancer patients and thirty healthy female volunteers, were prospectively collected and evaluated for serum levels of Shh and IL-6 using human Shh and IL-6 specific enzyme-linked immunoassays. All patients were regularly monitored for event free survival (EFS) and overall survival (OS). Overall outcome analysis was based on serum Shh and IL-6 levels. In patients with progressive metastatic BC, both serum Shh and IL-6 concentrations were elevated in 44% (29 of 65) and 63% (41 of 65) of patients, respectively, at a statistically significant level [Shh (p = 0.0001) and IL-6 (p = 0.0001)] compared to the low levels in healthy volunteers. Serum levels tended to increase with metastatic progression and lymph node positivity. High serum Shh and IL-6 levels were associated with poor EFS and OS opposite to the negative or lower levels in serum Shh and IL-6. The elevated levels of both serum Shh and IL-6 were mainly observed in BC patients who had a significantly higher risk of early recurrence and bone metastasis, and associated with a worse survival for patients with progressive metastatic BC. Further studies are warranted for validating these biomarkers as prognostic tools in a larger patient cohort and in a longer follow-up study.

Abstract
Many breast cancer survivors have to deal with a variety of psychological and physiological sequelae including impaired immune responses. The primary purpose of this randomized controlled trial was to determine the efficacy of a mindfulness‐based stress reduction (MBSR) intervention for mood disorders in women with breast cancer. Secondary outcomes were symptom experience, health status, coping capacity, mindfulness, posttraumatic growth, and immune status. This RTC assigned 166 women with breast cancer to one of three groups: MBSR (8 weekly group sessions of MBSR), active controls (self‐instructing MBSR) and non‐MBSR. The primary outcome measure was the Hospital Anxiety and Depression Scale. Secondary outcome measures were: Memorial Symptom Assessment Scale, SF‐36, Sense of Coherence, Five Facets of Mindfulness Questionnaire, and Posttraumatic Growth Index. Blood samples were analyzed using flow cytometry for NK‐cell activity (FANKIA) and lymphocyte phenotyping; concentrations of cytokines were determined in sera using commercial high sensitivity IL‐6 and IL‐8 ELISA (enzyme‐linked immunosorbent assay) kits. Results provide evidence for beneficial effects of MBSR on psychological and biological responses. Women in the MBSR group experienced significant improvements in depression scores, with a mean pre‐MBSR HAD‐score of 4.3 and post‐MBSR score of 3.3 (P = 0.001), and compared to non‐MBSR (P = 0.015). Significant improvements on scores for distress, symptom burden, and mental health were also observed. Furthermore, MBSR facilitated coping capacity as well as mindfulness and posttraumatic growth. Significant benefits in immune response within the MBSR group and between groups were observed. MBSR have potential for alleviating depression, symptom experience, and for enhancing coping capacity, mindfulness and posttraumatic growth, which may improve breast cancer survivorship. MBSR also led to beneficial effect on immune function; the clinical implications of this finding merit further research.

Abstract
Interleukin-8 (IL-8) is an angiogenic chemokine that plays a potent role in both development and progression of many human malignancies. However, there are no data about the role of IL-8 polymorphism in development of osteosarcoma. A hospital-based case-control study was conducted among 190 patients with osteosarcoma and 190 healthy controls to investigate the possible association between the IL-8 -251 A/T and +781 C/T polymorphisms, respectively, and the risk of osteosarcoma. Significant differences of genotype distribution were observed between osteosarcoma cases and controls at the IL-8 -251T/A genotypes. Compared with the IL-8 -251T/A homozygote TT, the heterozygous TA genotype was associated with significantly increased risk for osteosarcoma (odds ratio (OR) = 2.16, 95 % confidence interval (CI) = (1.38-4.52), P = 0.021); the AA genotype was associated with increased risk for osteosarcoma (OR = 1.94, 95 % CI = 1.31-3.83, P = 0.018). TA and AA combined variants were associated with increased risk for osteosarcoma compared with the TT genotype (OR = 1.72, 95 % CI = 1.45-4.41, P = 0.023). Moreover, the genotype AA of IL-8 -251T/A carried a higher risk of osteosarcoma metastasis and later Enneking stages, compared with the TT genotype. However, the genotype and allele frequencies of IL-8 +781 C/T polymorphisms in osteosarcoma patients were not significantly different from controls. Our results showed that the IL-8 -251 A/T genotype was associated with increased risk for development and metastasis of osteosarcoma in Chinese Han population.

Abstract
PURPOSE To evaluate the efficacy of radionuclide palliative therapy (RPT) in women suffering from painful metastatic bone disease (MBD) due to breast cancer (BrCa), and to investigate the possible relationship between the RPT efficacy and cytokines levels. METHODS Sixty-three BrCa women patients with MBD enrolled in a prospective, nonrandomized study. Thirty were treated with Rhenium-186-hydroxyethylidenediphosphonic acid ((186)Re-HEDP), 21 with Strontium-89-Chloride ((89)Sr-Cl2), and 12 with Samarium-153-thylenediaminetetramethylenephosphonic acid ((153)Sm-EDTMP). Blood samples were collected pre- and post-therapy to assess the interleukin (IL)-2, IL-6 and tumor necrosis factor (TNF)-a titers. The palliative effect of the treatment was evaluated using a modified Wisconsin test. RESULTS All three radiopharmaceuticals were equally effective in pain relief. Pain palliation was complete in 52% of patients, partial in 31%, and absent in 16%. Responders to therapy had higher IL-2 and lower IL-6/TNF-a concentrations, compared with nonresponders, even though statistically significant difference in cytokines levels between responders and nonresponders before treatment was noted only for IL-6. CONCLUSION All used radiopharmaceuticals had the same therapeutic effect. Pretherapy low titers of IL-6 levels seems to have a favorable prognostic value for the therapeutic outcome, while IL-2 and TNF-a alterations pre- and post-therapy can only serve as markers of a better RPT response.

Abstract
Background The stress of a breast cancer diagnosis and its treatment can produce a variety of psychosocial sequelae including impaired immune responses. Mindfulness Based Stress Reduction (MBSR) is a structured complementary program that incorporates meditation, yoga and mind-body exercises. Despite promising empirical evidence for the efficacy of MBSR, there is a need for randomized controlled trials (RCT). There is also a need for RCTs investigating the efficacy of psychosocial interventions on mood disorder and immune response in women with breast cancer. Therefore, the overall aim is to determine the efficacy of a Mindfulness Based Stress Reduction (MBSR) intervention on well-being and immune response in women with breast cancer. Methods and design In this RCT, patients diagnosed with breast cancer, will consecutively be recruited to participate. Participants will be randomized into one of three groups: MBSR Intervention I (weekly group sessions + self-instructing program), MBSR Intervention II (self-instructing program), and Controls (non-MBSR). Data will be collected before start of intervention, and 3, 6, and 12 months and thereafter yearly up to 5 years. This study may contribute to evidence-based knowledge concerning the efficacy of MBSR to support patient empowerment to regain health in breast cancer disease. Discussion The present study may contribute to evidence-based knowledge concerning the efficacy of mindfulness training to support patient empowerment to regain health in a breast cancer disease. If MBSR is effective for symptom relief and quality of life, the method will have significant clinical relevance that may generate standard of care for patients with breast cancer.

Abstract
Considering the protumorigenic roles of interleukin-6 (IL-6) transsignaling, we assessed the serum levels of IL-6, soluble interleukin-6 receptor (sIL-6R), and soluble glycoprotein 130 (sgp130) in 143 patients with breast cancer. Serum levels of IL-6 were elevated with advanced T and N stage. Serum levels of sIL-6R were lower in patients with estrogen receptor-positive cancer. The median values of IL-6 and sgp130 did not differ between patients with recurrence and those without recurrence. However, higher serum levels of sIL-6R at diagnosis were associated with significantly shorter relapse-free survival in patients with estrogen receptor-positive breast cancer.

Abstract
Cervical cancer is the most common gynecological cancer and one of the major causes of female cancer-related death worldwide particularly in developing countries. Thus far, there are a few in vivo models have been developed in investigating this type of cancer. In this study, we induced cervical cancer in Balb/c mice by exploiting the carcinogenic property of diestylstilbestrol (DES). The Balb/c pregnant mice were given subcutaneous (SC) injection of 67μg/kg body weight of DES on GD 13, and the mice gave birth approximately at gestation day 19-22. Female offspring were reared and the body weight was recorded once weekly. The female offspring were sacrificed at age of 5 months. Upon termination, blood was collected in a plain tube via cardiac puncture and the reproductive tracts were collected and weighed. The reproductive tract sections were stained using H&E for observation of pathological changes. The progression of disease state was monitored by measuring the level of serum interleukin (IL-6) using the Mouse IL-6 ELISA Assay Kit (BD OptEIA™, USA). All parameters were compared with Not-induced group. The outcome of this study demonstrated a significant difference in body weight gain, reproductive organ weight, diameter of cervix and the level of serum IL-6 in the Induced group as compared to the Not-induced group (P<0.05). Histopathological findings revealed the presence of adenosis only in the Induced group. It shows that DES could be employed as an agent to induce cervical carcinogenesis in animal model. In addition to that, new potential anti-cancer agents from various sources could be further evaluated using this technique.

Abstract
BACKGROUND Elevated IL-6 levels have been associated with advanced stage of breast cancer and metastasis-related morbidity. The present prospective study was carried out to assess the effect of neoadjuvant chemotherapy on circulating levels of serum IL-6 in patients of locally advanced carcinoma breast. MATERIALS All locally advanced carcinoma breast cases presenting to the surgery out patient's department were included in the study excluding pregnant or lactating females and those patients who were unfit for anthracycline based chemotherapy. A total of 30 cases were included. The various parameters that were evaluated include detailed clinico-pathological profile and IL-6 levels. Clinical staging using TNM classification was performed in all enrolled patients. This included documenting tumor size (on USG), node status and metastatic workup. First blood sample was collected before start of any treatment. Second blood sample was collected after 3 cycles of chemotherapy. Blood was centrifuged within 30 min and serum kept at -80 °C until analysis for IL-6. IL-6 levels were quantified by ELISA. RESULTS Majority of patients presented in stage T3N1M0 (66.66%). The serum level of IL-6 increased as the disease progressed from T3N1M0 to T4dN2M0 (41.4 ± 31.9 pg/ml vs. 164.0 ± 31.1 pg/ml respectively). A progressive reduction in IL-6 levels with subsequent cycles of chemotherapy was observed which was statistically significant (from 72.8 ± 56.0 pg/ml to 47.0 ± 61.9 pg/ml; p value 0.002 wilcoxan signed rank test). CONCLUSION Our study shows a consistent decline in the IL-6 levels with chemotherapy. Upon ratification of our findings by large population based multi centric studies, we may state with conviction that a single blood test as serum level of IL6 will prove beneficial in assessing the efficacy of chemotherapy.

Breast Cancer Res 2012; 13:R117. [PMID: 22112244 PMCID: PMC3326559 DOI: 10.1186/bcr3060] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2011] [Revised: 09/16/2011] [Accepted: 11/23/2011] [Indexed: 02/01/2023] Open
Abstract
Introduction The clinical efficacy of trastuzumab and taxanes is at least partly related to their ability to mediate or promote antitumor immune responses. On these grounds, a careful analysis of basal immune profile may be capital to dissect the heterogeneity of clinical responses to these drugs in patients with locally advanced breast cancer undergoing neoadjuvant chemotherapy. Methods Blood samples were collected from 61 locally advanced breast cancers (36 HER2- and 25 HER2+) at diagnosis and from 23 healthy women. Immunophenotypic profiling of circulating and intratumor immune cells, including regulatory T (Treg) cells, was assessed by flow cytometry and immunohistochemistry, respectively. Serum levels of 10 different cytokines were assessed by multiplex immunoassays. CD8+ T cell responses to multiple tumor-associated antigens (TAA) were evaluated by IFN-γ-enzyme-linked immunosorbent spot (ELISPOT). The Student's t test for two tailed distributions and the Wilcoxon two-sample test were used for the statistical analysis of the data. Results The proportion of circulating immune effectors was similar in HER2+ patients and healthy donors, whereas higher percentages of natural killer and Treg cells and a lower CD4+/CD8+ T cell ratio (with a prevalence of naïve and central memory CD8+ T cells) were observed in HER2- cases. Higher numbers of circulating CD8+ T cells specific for several HLA-A*0201-restricted TAA-derived peptides were observed in HER2+ cases, together with a higher prevalence of intratumor CD8+ T cells. Serum cytokine profile of HER2+ patients was similar to that of controls, whereas HER2- cases showed significantly lower cytokine amounts compared to healthy women (IL-2, IL-8, IL-6) and HER2+ cases (IL-2, IL-1β, IL-8, IL-6, IL-10). Conclusions Compared to HER2- cases, patients with HER2-overexpressing locally advanced breast cancer show a more limited tumor-related immune suppression. This may account for the clinical benefit achieved in this subset of patients with the use of drugs acting through, but also promoting, immune-mediated effects.

Abstract
Metastasis to multiple organs is the primary cause of mortality in breast cancer patients. The poor prognosis for patients with metastatic breast cancer and toxic side effects of currently available treatments necessitate the development of effective tumor-selective therapies. Neural stem cells (NSCs) possess inherent tumor tropic properties that enable them to overcome many obstacles of drug delivery that limit effective chemotherapy strategies for breast cancer. We report that increased NSC tropism to breast tumor cell lines is strongly correlated with the invasiveness of cancer cells. Interleukin 6 (IL-6) was identified as a major cytokine mediating NSC tropism to invasive breast cancer cells. We show for the first time in a preclinical mouse model of metastatic human breast cancer that NSCs preferentially target tumor metastases in multiple organs, including liver, lung, lymph nodes, and femur, versus the primary intramammary fat pad tumor. For proof-of-concept of stem cell-mediated breast cancer therapy, NSCs were genetically modified to secrete rabbit carboxylesterase (rCE), an enzyme that activates the CPT-11 prodrug to SN-38, a potent topoisomerase I inhibitor, to effect tumor-localized chemotherapy. In vitro data demonstrate that exposure of breast cancer cells to conditioned media from rCE-secreting NSCs (NSC.rCE) increased their sensitivity to CPT-11 by 200-fold. In vivo, treatment of tumor-bearing mice with NSC.rCE cells in combination with CPT-11 resulted in reduction of metastatic tumor burden in lung and lymph nodes. These data suggest that NSC-mediated enzyme/prodrug therapy may be more effective and less toxic than currently available chemotherapy strategies for breast cancer metastases.

Abstract
Interleukin-8 (IL-8), a chemokine with a defining CXC amino acid motif, is known to possess tumorigenic and proangiogenic properties. Overexpression of IL-8 has been detected in many human tumors, including colorectal cancer (CRC), and is associated with poor prognosis. The goal of our study was to determine the role of IL-8 overexpression in CRC cells in vitro and in vivo. We stably transfected the IL-8 cDNA into two human colon cancer cell lines, HCT116 and Caco2, and selected IL-8-secreting transfectants. Real-time RT-PCR confirmed that IL-8 mRNA was overexpressed in IL-8 transfectants with 45- to 85-fold higher than parental cells. The IL-8-transfected clones secreted 19- to 28-fold more IL-8 protein than control and parental cells as detected by ELISA. The IL-8 transfectants demonstrated increased cellular proliferation, cell migration and invasion based on functional assays. Growth inhibition studies showed that IL-8 overexpression lead to a significant resistance to oxaliplatin (p < 0.0001). Inhibition of IL-8 overexpression with small interfering RNA reversed the observed increases in tumorigenic functions and oxaliplatin resistance, suggesting that IL-8 not only provides a proliferative advantage but also promotes the metastatic potential of colon cancer cells. Using a tumor xenograft model, IL-8-expressing cells formed significantly larger tumors than the control cells with increased microvessel density. Together, these findings indicate that overexpression of IL-8 promotes tumor growth, metastasis, chemoresistance and angiogenesis, implying IL-8 to be an important therapeutic target in CRC.

Abstract
INTRODUCTION Breast cancer, the most common malignancy in women, still holds many secrets. The causes for non-hereditary breast cancer are still unknown. To elucidate any role for circulating naturally secreted proteins, a screen of secreted proteins' influence of MCF10A cell anchorage independent growth was set up. METHODS To systematically screen secreted proteins for their capacity to transform mammalian breast epithelial cells, a soft agar screen of MCF10A cells was performed using a library of ~ 470 secreted proteins. A high concentration of infecting viral particles was used to obtain multiple infections in individual cells to specifically study the combined effect of multiple secreted proteins. RESULTS Several known breast cancer factors, such as Wnt, FGF and IL were retained, as well as factors that were previously unknown to have a role in breast cancer, such as paraoxonase 1 and fibroblast growth factor binding protein 2. Additionally, a combinatory role of Interleukin 6 with other factors in MCF10A anchorage-independent growth is demonstrated. CONCLUSION The transforming effect of combinations of IL6 with other secreted proteins allows studying the transformation of mammary epithelial cells in vitro, and may also have implications in in vivo studies where secreted proteins are upregulated or overexpressed.

Abstract
Breast and ovarian cancer continue to be a significant source of morbidity and mortality. Improved understanding of signalling pathways related to growth and apoptosis has led to targeted treatments and modest improvement in long term outcomes. However, it has become increasingly clear that tumor factors alone are not the sole determinants of outcome in patients with breast and ovarian cancer. The tumor microenvironment and other immunologic host processes play an integral role in the overall interactions between disease, host and treatment. Cytokines play a major role in the immune response to tumors. Single nucleotide polymorphisms (SNPs) in the regulatory or coding regions of many cytokine genes lead to functional alterations in the transcriptional regulation of these genes or the proteins they encode. This review examines the current literature linking functional variants in cytokine and other immune genes to outcomes in breast and ovarian cancer. We have focused on those involved in the proinflammatory response (IL-6, TNF-alpha), apoptosis (TGF-beta, Fas, FasL, C1QA), angiogenesis (IL-8) and autoimmunity (IL-10). While much remains to be learned about the mechanisms underlying these variants and their impact on tumor behavior, this area holds promise for future development of prognostic profiles and therapeutics exploiting the immune response.

Abstract
Interleukin-6 modulates immune response, estrogen production, and growth pathways in breast cancer. We evaluated the effect of several common, functional interleukin-6 promoter variants in node-positive breast cancer patients enrolled on a multicenter, cooperative group, adjuvant chemotherapy trial to determine whether these variants were associated with clinical outcome overall and by estrogen receptor tumor phenotype. Genomic DNA and clinical data were collected from a clinical trial of adjuvant anthracycline-based chemotherapy followed by randomization to high-dose cyclophosphamide/thiotepa or observation (Intergroup Trial 0121). Genotyping for -174G>C (rs1800795), -597G>A (rs1800797), and -572G>C (rs1800796) was done by site-specific PCR and PyroSequencing, whereas the -373A(n)T(n) repeat was directly sequenced. Log-rank tests and Cox modeling were used to compare outcomes by genotype/haplotype and other factors. Three hundred forty-six patients (64% of trial) had corresponding genotype/clinical data available and did not differ from overall trial participants. After adjustment, patients with estrogen receptor-positive tumors and genotypes 597 GG or 174 GG had significantly worse disease-free survival [hazard ratio (HR), 1.6; P = 0.02 and HR, 1.71; P = 0.007, respectively], whereas the 373 8A12T repeat appeared to be protective (HR, 0.62; P = 0.02). The presence of at least one copy of the haplotype ([-597G, -572G, -373[10A/11T], -174G]) was associated with worse disease-free survival (HR, 1.46; P = 0.04). Kaplan-Meier plots show that all patients in this group relapsed by 24 months from diagnosis. This poor-risk haplotype was quite common overall (estimated frequency, 0.20) and twice as frequent among Blacks (estimated frequency, 0.41).

Abstract
Interleukin-8 (IL-8) is an angiogenic chemokine that plays a potent role in both development and progression of many human malignancies including nasopharyngeal carcinoma (NPC). In the present study, we evaluated the susceptibility and prognostic implications of the (-251) T/A genetic variation in IL-8 in NPC. We used the allele-specific polymerase chain reaction to characterize the variation of the IL-8 promoter region for 160 unrelated Tunisian patients with NPC and 169 healthy control subjects. There was a significant association between the homozygotes IL-8 (-251) AA genotype and nasopharyngeal carcinoma (OR = 2.46; P = 0.004). The presence of the IL-8 (-251) AA genotype was highly associated with elevated NPC risk for male patients. A significant association was demonstrated between the IL-8 (-251) AA genotype and the aggressive forms of NPC as defined by large tumor size, lymph node metastasis, and advanced stages. Moreover, the presence of the IL-8 (-251) AA genotype indicated a significant association with decreased overall survival. Our findings suggest that the IL-8 promoter polymorphism is associated with increased nasopharyngeal carcinoma risk, particularly in males, as well as disease progress, supporting our hypothesis for IL-8 involvement in NPC pathogenesis.

Abstract
p53 Mutations are found in up to 30% of breast cancers and peptides derived from over-expressed p53 protein are presented by class I HLA molecules and may act as tumor-associated epitopes in cancer vaccines. A dendritic cell (DC) based p53 targeting vaccine was analyzed in HLA-A2+ patients with progressive advanced breast cancer. DCs were loaded with 3 wild-type and 3 P2 anchor modified HLA-A2 binding p53 peptides. Patients received up to 10 sc vaccinations with 5 x 10(6) p53-peptide loaded DC with 1-2 weeks interval. Concomitantly, 6 MIU/m(2) interleukine-2 was administered sc. Results from a phase II trial including 26 patients with verified progressive breast cancer are presented. Seven patients discontinued treatment after only 2-3 vaccination weeks due to rapid disease progression or death. Nineteen patients were available for first evaluation after 6 vaccinations; 8/19 evaluable patients attained stable disease (SD) or minor regression while 11/19 patients had progressive disease (PD), indicating an effect of p53-specific immune therapy. This was supported by: (1) a positive correlation between p53 expression of tumor and observed SD, (2) therapy induced p53 specific T cells in 4/7 patients with SD but only in 2/9 patients with PD, and (3) significant response associated changes in serum YKL-40 and IL-6 levels identifying these biomarkers as possible candidates for monitoring of response in connection with DC based cancer immunotherapy. In conclusion, a significant fraction of breast cancer patients obtained SD during p53-targeting DC therapy. Data encourage initiation of a randomized trial in p53 positive patients evaluating the impact on progression free survival.

Abstract
Interleukins (ILs) are known to play a fundamental role in cancer. We investigated the serum levels of IL-8 and IL-12, in breast cancer patients, and their relationship with the prognostic parameters and therapy. Forty eight patients with pathologically verified breast carcinoma and 21 healthy controls were enrolled into the study. Serum samples were obtained at baseline and after two cycles of chemotherapy. Serum IL-8 and IL-12 levels were determined using enzyme-linked immunosorbent assay (ELISA). There was no significant difference in the baseline serum IL-8 and IL-12 levels between breast cancer patients and healthy controls (p = 0.365 and p = 0.871, respectively), no significant correlation between the prognostic parameters and the serum IL-8, IL-12 levels. However, in the subgroup consisting of metastatic breast cancer patients, baseline serum IL-8 levels were significantly higher compared with non-metastatic disease (p = 0.047). Anthracycline-based chemotherapy and the addition of taxane did not change the levels of both serum IL-8 and IL-12. Serum IL-8 level may be useful in determining metastatic breast cancer. Larger studies are needed to confirm this finding.

Abstract
Cytokines are factors that are known to have both tumor-promoting and inhibitory effects on breast cancer growth depending presumably on their relative concentrations and the presence of other modulating factors. Different cytokines play an important role in controlling the immune system. Interleukin-6 (IL-6) is a pleiotropic cytokine with obviously tumor-promoting and tumor-inhibitory effects. Here, we review the role of IL-6 in in vitro experiments of breast tumor cells, in breast tumor tissues (BTs) and assess its potential as a prognostic indicator in breast cancer patients. A literature search was conducted using PubMed, restricted to articles published in English language. In summary, results regarding the effect of IL-6 on breast tumor cells and on BTs are not unique indicating both tumor-promoting and inhibitory effects of IL-6. Concerning patients' serum IL-6 levels, data are surprisingly unique showing IL-6 to be a negative prognosticator in breast tumor patients.

Abstract
Interleukin-8 (IL-8), a potent chemoattractant, has been demonstrated to contribute to human cancer progression through its potential functions as a mitogenic, angiogenic, and motogenic factor. We designed a broad study to investigate whether genetic variation in IL-8 has implications for susceptibility to and prognosis in breast carcinoma. We used the allele-specific polymerase chain reaction to characterize the variation of the IL-8 promoter region for 308 unrelated Tunisian patients with breast carcinoma and 236 healthy control subjects. Associations of the clinicopathologic parameters and the genetic marker with the rates of the breast carcinoma-specific overall survival and the disease-free survival were assessed using univariate and multivariate analyses. A significantly increased risk of breast carcinoma was associated with heterozygous IL-8 (-251) TA (OR=1.58, p=0.02) and homozygous IL-8 (-251) AA (OR=1.76, p=0.01) variants. A significant association between the IL-8 (-251) AA homozygous genotype and the aggressive phenotype of breast carcinoma as defined by the high histological grade, auxiliary's lymph node metastasis, and large tumor size was found. The IL-8 (-251) A allele manifested a significant association with decreased overall survival and disease-free survival for breast carcinoma patients. The polymorphism in the promoter region of the IL-8 gene may not only represent a marker for the increased risk of breast carcinoma but also predict the clinical outcome.

Abstract
PURPOSE The prognostic significance of serum interleukin (IL)-8 was evaluated in patients with metastatic breast cancer. The predictive value of serum IL-8 for the presence of occult metastatic tumor cells in bone marrow aspirates was evaluated in patients with operable and metastatic breast cancer. EXPERIMENTAL DESIGN Serum IL-8 was measured in healthy controls, patients with operable breast cancer, and patients with untreated, progressive metastatic breast cancer. In 69 patients with either operable or advanced breast cancer, occult cytokeratin-positive cells were counted in bone marrow aspirates. RESULTS Serum IL-8 levels are increased in 67% (52 of 77) of patients with advanced breast cancer. Overall, these levels are significantly higher in patients with breast cancer compared with healthy volunteers (P < 0.001). The IL-8 levels increase significantly in patients with more advanced disease. An elevated serum IL-8 is related to an accelerated clinical course, a higher tumor load, and the presence of liver or lymph node involvement. A multivariate analysis indicates that serum IL-8 is an independent significant factor for postrelapse survival. There was a significant difference between serum IL-8 levels in patients with or without occult cytokeratin-positive bone marrow cells (P < 0.04). Serum IL-8 levels also showed an association with the number of these cells (P < 0.01). CONCLUSIONS Serum IL-8 is increased in patients with breast cancer and has an independent prognostic significance for postrelapse survival. The observations on the relationship between occult cytokeratin-positive bone marrow cells corroborate the concept of IL-8 acting as a contributor to the process of tumor cell dissemination. Similarly, the relationship between serum IL-8 and nodal stage at presentation deserves further study. These results further expand the concept that inflammation and inflammatory cytokines are critical components of tumor progression.

Abstract
PURPOSE Tumor necrosis factor (TNF) alpha is a key player in the tumor microenvironment and is involved in the pathogenesis of breast cancer. Etanercept is a recombinant human soluble p75 TNF receptor that binds to TNF-alpha and renders it biologically unavailable. In the current study, we sought to determine the toxicity, biological activity, and therapeutic efficacy of Etanercept in metastatic breast cancer. EXPERIMENTAL DESIGN We initiated a Phase II, nonrandomized, open-labeled study in patients with progressive metastatic breast cancer refractory to conventional therapy (Phase I toxicity data were available in patients with rheumatoid arthritis). Etanercept was administered subcutaneously at a dose of 25 mg twice weekly until disease progression. RESULTS Sixteen patients were recruited [median age 53 years (range, 34 to 74)]. A total of 141.6 weeks of therapy was administered (median of 8.1 weeks). Seven patients received > or =12 weeks of therapy. The most common side effects were injection site reactions (6), fatigue (5), loss of appetite (2), nausea (1), headache (1), and dizziness (1). Brief period of disease stabilization was seen in 1 patient lasting for 16.4 weeks. Immunoreactive TNF-alpha was elevated within 24 hours of therapy and persisted until the end of treatment (days 7, 28, 56, and 84). Phytohemagglutinin stimulates the production of interleukin-6 and CCL2 in peripheral blood cells, and the ability of Etanercept to modulate this response was assessed in a cytokine release assay. A consistent decrease in interleukin-6 and CCL2 level was seen compared with pretreatment values in serial blood samples (days 1, 7, 28, 56, and 84). CONCLUSIONS Our study shows the safety and biological activity of Etanercept in breast cancer and provides data to assess pharmacodynamic endpoints of different schedules of Etanercept and combinations with chemotherapy or other biological therapies.

Abstract
Abstract
We previously designed and synthesized the new nuclear factor κB (NF-κB) inhibitor dehydroxymethylepoxyquinomicin (DHMEQ) derived from the structure of the antibiotic epoxyquinomicin C. We looked into the effect of DHMEQ on cellular phenotypes and tumor growth in mice injected with human breast carcinoma cell line MDA-MB-231 or MCF-7. In estrogen-independent breast adenocarcinoma cell line MDA-MB-231, NF-κB is constitutively activated. The addition of DHMEQ (10 μg/mL) completely inhibited the activated NF-κB for at least 8 hours. On the other hand, NF-κB is not activated in estrogen-dependent MCF-7 cells. In this cell line, DHMEQ completely inhibited the tumor necrosis factor-α-induced activation of NF-κB. DHMEQ did not inhibit the degradation of IκB but inhibited the nuclear translocation of NF-κB by both p65/p50 and RelB/p52 pathways. MDA-MB-231 cells secrete interleukin (IL)-6 and IL-8 without stimulation, and DHMEQ decreased the secretion levels of both cytokines. When MDA-MB-231 or MCF-7 cells were stimulated by tumor necrosis factor-α, the inhibitory effects of DHMEQ were still maintained. I.p. administration of DHMEQ (thrice a week) significantly inhibited the tumor growth of MDA-MB-231 (12 mg/kg) or MCF-7 (4 mg/kg) in severe combined immunodeficiency mice. No toxicity was observed during the experiment, including the loss of body weight. An immunohistological study on resected MCF-7 tumors showed that DHMEQ inhibited angiogenesis and promoted apoptosis. Furthermore, in Adriamycin-resistant MCF-7 cells highly expressing multidrug resistance gene-1, DHMEQ also exhibited the above capability, including down-regulation of IL-8. Thus, DHMEQ might be a potent drug for the treatment of various breast carcinomas by inhibiting the NF-κB activity.

Abstract
The regulation of secretion of the angiogenic factors CXCL8 and Vascular Endothelial Growth Factors (VEGF) was determined in breast tumor cells and in monocytic cells (as host cells that contribute to breast cancer). CXCL8 secretion, and partly the secretion of VEGF, were up-regulated in monocytic cells, but not in breast tumor cells, by the CC chemokines CCL5 and CCL2. EGF potently up-regulated CXCL8 secretion by breast tumor cells, and its effect was promoted by a consecutive treatment of the cells by estrogen and progesterone. These findings provide evidence for a complex set of pro-malignancy factors that may control the expression of angiogenic mediators at breast tumor sites.

Abstract
Interleukin-6 (IL-6) is a potent growth factor for the proliferation of multiple myeloma (MM), which accounts for 1-2% of all human cancers. In this study we investigated the effects of IL-6 in various doses on the following parameters in the human myeloma cell line OPM-2: membrane expression of IL-6 receptor (IL-6R) and gp130, proliferation of the tumour cells and the amount of the soluble IL-6 receptor (sIL-6R) in the supernatant. Additionally, we tested the same parameters with the immunomodulator Viscum album (VA) extract. The expression of surface IL-6R and gp130 was analysed by FACS, the measurements of proliferation using the BrdU incorporation during DNA synthesis, and the determination of sIL-6R in the supernatant by ELISA. OPM-2 cells proliferate spontaneously (doubling time: 48 h), IL-6-production was not detectable. The exogenous IL-6 upregulated its own receptor up to a mean of 180% of controls at 5 ng/ml (P < 0.001), higher or lower doses were less effective. The membrane expression of gp130 was downregulated to 1-2%. IL-6 led to increase of the sIL-6R in the supernatant (P < 0.001) and raised the proliferation of the myeloma cells up to a mean of 124% (P < 0.001). These results indicate that the human myeloma cell line OPM-2 has an autocrine IL-6 regulation mechanism, with an additional paracrine signalling by exogenous IL-6. This is the first report that IL-6 inhibits the membrane expression of gp130, although the proliferation of the myeloma cells increases. VA extract did not affect survival, the expression of surface receptors IL-6 and gp130 or the amount of sIL-6R in the supernatant. However, the proliferation of the tumour cells was inhibited significantly (P < 0.05) suggesting a possible arrest in the cell cycle.

Abstract
The progression of breast cancer is affected by multiple cellular and microenvironmental components. The monocyte chemoattractant MCP-1, IL-6 and matrix metalloproteinases (MMP) were suggested to promote, each on its own, breast cancer progression. We recently demonstrated that the high-tumorigenicity phenotype of the DA3 and CSML murine mammary adenocarcinoma cells is correlated with a high expression of MCP-1, IL-6 and MMP. This raised the possibility that common intrinsic tumor-derived factors regulate the concordant expression of these 3 components. The aim of the present study was to gain insight into the mode by which the secretion of MCP-1, IL-6 and MMP from murine mammary adenocarcinoma cells is regulated. This was investigated in cellular clones established from a highly malignant variant of the DA3 tumor (DA3-high). We also determined the secretion of the antimalignancy chemokine IP-10 from these cells. The results indicate that the secretion levels of IL-6, MMP and IP-10 varied between the clones. In contrast, all the clones secreted uniformly high levels of MCP-1, suggesting that MCP-1 constitutes an important feature of the malignancy phenotype of mammary carcinoma. In most of the clones, elevated levels of 1 of the 3 promalignancy factors did not correlate with a high expression of the other 2 factors and vice versa. These findings indicate that the 3 promalignancy factors are not coregulated by a common intrinsic tumor-derived factor. Rather, these results suggest that the individual capacities of the different clones to secrete these factors are summed up in the high-malignancy DA3 parental tumor population, which secretes relatively high levels of MCP-1, IL-6 and MMP as compared to DA3 cells expressing a low-malignancy phenotype. In contrast to the lack of coordinated intrinsic regulation of MCP-1, IL-6 and MMP, it was found that recombinant TNFalpha, a product of tumor-associated macrophages contributing to breast cancer progression, upregulated the secretion of MCP-1, IL-6 and MMP from all the clones. These results suggest a key role for this microenvironmental, monocyte-derived cytokine in the coordinated regulation of these 3 molecules. Furthermore, additional results demonstrated that monocytic cell-derived TNFalpha upregulated MCP-1 secretion from the tumor cells and that MCP-1 in turn promoted the secretion of TNFalpha from monocytic cells. This may result in a positive feedback loop, whereby the tumor cells and the monocytic cells at tumor site promote each other's ability to express and secrete promalignancy factors. We next attempted to assess the contribution of the promalignancy factors MCP-1, IL-6 and MMP and of the antimalignancy factor IP-10 to mammary adenocarcinoma progression. To this end, a preliminary formula was developed in which the net balance between secretion levels of the promalignancy factors and that of the antimalignancy IP-10 chemokine from different clones was related to their in vivo tumorigenicity profile. This formula suggests that a balance between the secretion levels of these factors plays an important role in determining the malignancy phenotype of mammary carcinomas. In all, our findings demonstrate that the mammary tumor cell population is composed of a heterogeneous assortment of clones whose individual characteristics are averaged in the whole population. The malignancy potential of such tumors is thus determined, inter alia, by a combinatorial effect of several promalignancy and antimalignancy factors secreted from each of the clones comprising these tumors. Our results also suggest that the expression of such factors is determined by several nonmutually exclusive regulatory mechanisms.

Abstract
BACKGROUND Advances in immunotherapy for the treatment of patients with malignant disease have led to increasingly successful use of these methods in the clinical setting. This review presents findings from recent studies that have explored improved methods for the presentation of tumor-associated antigens and for the restoration of tumor specific immune responses using cytokine therapy. METHODS A review of human clinical trial research on immune cytokines from 1995 (MEDLINE) to the present was conducted. Particular attention was focused on articles that reported results from Phase II or later clinical studies in patients with malignant disease. RESULTS The defects in cellular immunity commonly seen in patients with malignancies often are expressed as tumor specific anergy. Reversing patient tolerance to tumor antigens may be accomplished by treatment with immunoregulatory cytokines, such as Flt-3 and granulocyte-macrophage-colony stimulating factor, that mature and activate dendritic cells. Published clinical studies indicate that granulocyte-macrophage-colony stimulating factor stimulates antigen-presenting cells and has promising antitumor activity as an adjunct or as stand-alone therapy for patients with malignant disease, including leukemia, melanoma, breast carcinoma, prostate carcinoma, and renal cell carcinoma. CONCLUSIONS Immune-modulating cytokines may be used alone or in combination with other treatments to help restore immune function, improve response to tumor-associated antigens, and reduce the toxic effects of standard antitumor therapies. The evolving understanding of how dendritic cells regulate immune responses and promising results from published studies of immune-enhancing cytokines in the treatment of patients with malignant disease support the conduct of randomized clinical trials to confirm the clinical benefit of these immunotherapeutic strategies.

Abstract
Interleukin-6 (IL-6) is a multifunctional cytokine produced by macrophages, T cells, B cells, endothelial cells and tumour cells. Interleukin-6 is able to promote tumour growth by upregulating anti-apoptotic and angiogenic proteins in tumour cells. In murine models it has been demonstrated that antibodies against IL-6 diminish tumour growth. Several reports have highlighted the prognostic importance of IL-6 in e.g., prostate and colon cancer. We addressed prospectively the prognostic significance of serum IL-6 (sIL-6), measured at diagnosis of metastasis, in 96 unselected and consecutive patients with progressive metastatic breast cancer before the initiation of systemic therapy. The median sIL-6 value for the breast cancer population was 6.6 +/- 2.1 pg/ml. Patients with 2 or more metastatic sites had higher sIL-6 values compared to those with only 1 metastatic site (respectively 8.15 +/- 1.7 pg/ml and 3.06 +/- 6.6 pg/ml; p < 0.001). Patients with liver metastasis (8.3 +/- 2.4 pg/ml), with pleural effusions (10.65 +/- 9.9 pg/ml) and with dominant visceral disease (8.15 +/- 3.3 pg/ml) had significantly higher values compared to those without liver metastases (4.5 +/- 3.4 pg/ml; p = 0.001), without pleural effusions (5.45 +/- 1.5 pg/ml; p = 0.0077) and with dominant bone disease (4.5 +/- 1.4 pg/ml; p = 0.007) respectively. No correlation between sIL-6 and age, menopausal status, performance status, tumour grade, body-mass index, histology and hormone receptor status was found. Multivariate analysis showed that high levels of serum IL-6 have independent prognostic value. We conclude that circulating IL-6 is associated with worse survival in patients with metastatic breast cancer and is correlated with the extent of disease.

Abstract
BACKGROUND We have shown previously that interleukin (IL) -1 beta- and IL-6-induced promatrilysin expression is mediated by an indirect pathway that requires NF kappa B-dependent synthesis of IL-6 and STAT3 signaling. We now demonstrate that IL-1 beta-induced but not IL-6-induced promatrilysin expression can be blocked by androgens in the prostate carcinoma cell line LNCaP (lymph node-derived carcinoma cells of the prostate). METHODS By using enzyme-linked immunosorbent assay analyses, promatrilysin was measured in LNCaP cells stimulated with IL-1 beta or IL-6 LNCaP-treated cells pretreated with testosterone. In addition, promatrilysin message was measured by using Northern analyses after IL-6-treated cells pretreated with testosterone. RESULTS In LNCaP treated with testosterone before IL-1 beta stimulation induced promatrilysin expression was completely abrogated. Furthermore, testosterone completely abrogated NF kappa B transactivation activity and induction of IL-6 protein expression and mRNA. Testosterone and 5 alpha-dihydrotestosterone did not have an inhibitory effect on IL-6-induced promatrilysin expression. Testosterone also had no effect on basal promatrilysin expression or basal NF kappa B transactivation activity. CONCLUSION From these data, we conclude that testosterone blocks IL-1 beta-induced promatrilysin expression by inhibition of NF kappa B transactivation activity, which in turn, blocks IL-6 expression. These data suggest a mechanism in vivo by which invasive and metastatic prostatic carcinoma cell clones refractory to hormone ablation therapy may develop after chemical or surgical castration. Furthermore, these data suggest that, perhaps, upstream targets such as the cytokines IL-1 beta and IL-6 may provide alternative drug targets for inhibiting prostate cancer progression.

Abstract
Tumor progression is a multistep process in which alterations in the expression of numerous gene products may give rise to highly malignant cellular variants. In the present study, we analyzed the differential expression of several genes in cellular variants of mammary adenocarcinomas with high or low malignancy potential, which originated in a common ancestor. To assess the generality of our findings, high and low malignancy variants were derived from two different mammary adenocarcinoma cell lines, namely DA3 and CSML cells. Of major importance is the fact that the differences between high- and low-malignancy variants observed in one system of mammary adenocarcinoma cells (DA3 cells) were identically reproduced in the other system of mammary adenocarcinoma cells (CSML cells). The high malignancy variants of tumors both DA3-high and CSML-high (previously called CSML-100), expressed higher levels of factors that induce monocyte migration than the low malignancy DA3-low and CSML-low (previously called CSML-0) variants. In addition, it was found that DA3-high and CSML-high cell variants expressed higher levels of monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6) and matrix metalloproteinases (MMPs) than the low malignancy variants (DA3-low and CSML-low). These results suggest that MCP-1, IL-6 and MMPs potentially contribute to mammary adenocarcinoma progression and that their expression is regulated by a common pathway. The expression of MCP-1, IL-6 and MMPs in both DA3-high and CSML-high cells was up-regulated by tumor necrosis factor alpha (TNFalpha). The fact that TNFalpha exerted similar effects on the expression of these three factors in both cell systems raises the possibility of a coordinated co-regulation of tumor-promoting factors.

Abstract
The serum levels of interleukin-6 (IL-6), sIL-6R and sgp130 were investigated in 76 cancer patients in comparison with 28 healthy controls. IL-6 is a multifunctional cytokine involved in certain malignant diseases. Soluble IL-6 receptor as agonist enhances the biological effect of released IL-6. Soluble gp130 as antagonist inhibits the effect of the IL-6/sIL-6R complex. Patients with different types of tumour (breast/gastrointestinal/uterine/ovarian/renal/bladder) were divided into four groups according to tumour stage and previous therapy (stage I + II without or after chemo-/radiotherapy, stage III + IV without or after chemo-/radiotherapy). The distribution of different tumour histotypes was similar in each group of patients. The levels of the three serum parameters were determined by ELISA. At each tumour stage either without or after chemo-/radiotherapy, the serum values of IL-6 were found to be not significantly different from those of controls. The values of sIL-6R were significantly elevated in stage I + II (P < 0.02) patients, with a borderline significance in stage III + IV (P = 0.06), in both cases only when no additional therapy was initiated. The serum values of sgp130 increased significantly at each tumour stage both without and after chemo-/radiotherapy (P < 0.001). A significant correlation was found between the values of sIL-6R and sgp130 in stage I + II (P < 0.02) and III + IV (P < 0.004) patients, in both cases without chemo-/radiotherapy. There were no other significant correlations. In conclusion, the simultaneous measurement of IL-6, sIL-6R and sgp130 in sera is an important factor in evaluating the biological effect of IL-6 in malignant disease. This is the first report to investigate sgp130 in cancer patients with different types of tumour.
