NOP58 induction potentiates chemoresistance of colorectal cancer cells through aerobic glycolysis as evidenced by proteomics analysis. Front Pharmacol 2023; 14:1295422. [PMID: 38149051 PMCID: PMC10750250 DOI: 10.3389/fphar.2023.1295422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Accepted: 11/30/2023] [Indexed: 12/28/2023] Open
Abstract
Introduction: The majority of individuals diagnosed with advanced colorectal cancer (CRC) will ultimately acquire resistance to 5-FU treatment. An increasing amount of evidence indicates that aerobic glycolysis performs a significant function in the progression and resistance of CRC. Nevertheless, the fundamental mechanisms remain to be fully understood. Methods: Proteomic analysis of 5-FU resistant CRC cells was implemented to identify and determine potential difference expression protein. Results: These proteins may exhibit resistance mechanisms that are potentially linked to the process of aerobic glycolysis. Herein, we found that nucleolar protein 58 (NOP58) has been overexpressed within two 5-FU resistant CRC cells, 116-5FuR and Lovo-5FuR. Meanwhile, the glycolysis rate of drug-resistant cancer cells has increased. NOP58 knockdown decreased glycolysis and enhanced the sensitivity of 116-5FuR and Lovo-5FuR cells to 5FU. Conclusion: The proteomic analysis of chemoresistance identifies a new target involved in the cellular adaption to 5-FU and therefore highlights a possible new therapeutic strategy to overcome this resistance.

ROS/PI3K/Akt and Wnt/β-catenin signalings activate HIF-1α-induced metabolic reprogramming to impart 5-fluorouracil resistance in colorectal cancer. J Exp Clin Cancer Res 2022; 41:15. [PMID: 34998404 PMCID: PMC8742403 DOI: 10.1186/s13046-021-02229-6] [Citation(s) in RCA: 145] [Impact Index Per Article: 72.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 12/19/2021] [Indexed: 12/24/2022] Open
Abstract
Background Acquired resistance of 5-fluorouracil (5-FU) remains a clinical challenge in colorectal cancer (CRC), and efforts to develop targeted agents to reduce resistance have not yielded success. Metabolic reprogramming is a key cancer hallmark and confers several tumor phenotypes including chemoresistance. Glucose metabolic reprogramming events of 5-FU resistance in CRC has not been evaluated, and whether abnormal glucose metabolism could impart 5-FU resistance in CRC is also poorly defined. Methods Three separate acquired 5-FU resistance CRC cell line models were generated, and glucose metabolism was assessed by measuring glucose and lactate utilization, RNA and protein expressions of glucose metabolism-related enzymes and changes of intermediate metabolites of glucose metabolite pool. The protein levels of hypoxia inducible factor 1α (HIF-1α) in primary tumors and circulating tumor cells of CRC patients were detected by immunohistochemistry and immunofluorescence. Stable HIF1A knockdown in cell models was established with a lentiviral system. The influence of both HIF1A gene knockdown and pharmacological inhibition on 5-FU resistance in CRC was evaluated in cell models in vivo and in vitro. Results The abnormality of glucose metabolism in 5-FU-resistant CRC were described in detail. The enhanced glycolysis and pentose phosphate pathway in CRC were associated with increased HIF-1α expression. HIF-1α-induced glucose metabolic reprogramming imparted 5-FU resistance in CRC. HIF-1α showed enhanced expression in 5-FU-resistant CRC cell lines and clinical specimens, and increased HIF-1α levels were associated with failure of fluorouracil analog-based chemotherapy in CRC patients and poor survival. Upregulation of HIF-1α in 5-FU-resistant CRC occurred through non-oxygen-dependent mechanisms of reactive oxygen species-mediated activation of PI3K/Akt signaling and aberrant activation of β-catenin in the nucleus. Both HIF-1α gene knock-down and pharmacological inhibition restored the sensitivity of CRC to 5-FU. Conclusions HIF-1α is a potential biomarker for 5-FU-resistant CRC, and targeting HIF-1a in combination with 5-FU may represent an effective therapeutic strategy in 5-FU-resistant CRC.

Sesquiterpene lactone Bigelovin induces apoptosis of colon cancer cells through inducing IKK-β degradation and suppressing nuclear factor kappa B activation. Anticancer Drugs 2021; 32:664-673.

Abstract
Bigelovin, a sesquiterpene lactone extracted from plant Inula helianthus aquatica, exhibited multiple interesting biological activities, including anti-inflammation, antiangiogenesis and cytotoxic action against cancer cells. In the present study, we found that Bigelovin reduced the viability of human colon cancer cells and induced their apoptosis in a time- and dose-dependent manner, with an IC50-5 μM. RNAseq and luciferase reporter analyses revealed that the nuclear factor kappa B (NF-κB) signaling was one of the most significantly inhibited pathways after Bigelovin treatment. Further systemic examination showed that exposure to Bigelovin resulted in ubiquitination and degradation of inhibitor of kappa-B kinase-beta (IKK-β) and decrease of IκB-α and p65 phosphorylation, which led to the downregulation of NF-κB-regulated genes expression. Moreover, enforced expression of exogenous IKK-β attenuated Bigelovin-induced NF-κB suppression and cell viability reduction. These results indicated that Bigelovin exerts a cytotoxic action against colon cancer cells through the induction of IKK-β degradation and consequently the inhibition of NF-κB signaling. Given the abnormal activation of NF-κB signaling in colorectal cancer (CRC) cells and the critical role of chronic inflammation in CRC development, it is conceivable that at least some colorectal cancer cells are addictive to NF-κB activation and targeting the pathway is an effective anti-CRC strategy.

EP4 receptor as a novel promising therapeutic target in colon cancer. Pathol Res Pract 2020; 216:153247.

Abstract
The most prevalent malignancy that can occur in the gastrointestinal tract is colon cancer. The current treatment options for colon cancer patients include chemotherapy, surgery, radiotherapy, immunotherapy, and targeted therapy. Although the chance of curing the disease in the early stages is high, there is no cure for almost all patients with advanced and metastatic disease. It has been found that over-activation of cyclooxygenase 2 (COX-2), followed by the production of prostaglandin E2 (PGE2) in patients with colon cancer are significantly increased. The tumorigenic function of COX-2 is mainly due to its role in the production of PGE2. PGE2, as a main generated prostanoid, has an essential role in growth and survival of colon cancer cell's. PGE2 exerts various effects in colon cancer cells including enhanced expansion, angiogenesis, survival, invasion, and migration. The signaling of PGE2 via the EP4 receptor has been shown to induce colon tumorigenesis. Moreover, the expression levels of the EP4 receptor significantly affect tumor growth and development. Overexpression of EP4 by various mechanisms increases survival and tumor vasculature in colon cancer cells. It seems that the pathway starting with COX2, continuing with PGE2, and ending with EP4 can promote the spread and growth of colon cancer. Therefore, targeting the COX-2/PGE2/EP4 axis can be considered as a worthy therapeutic approach to treat colon cancer. In this review, we have examined the role and different mechanisms that the EP4 receptor is involved in the development of colon cancer.

GOLFIG Chemo-Immunotherapy in Metastatic Colorectal Cancer Patients. A Critical Review on a Long-Lasting Follow-Up. Front Oncol 2019; 9:1102. [PMID: 31781481 PMCID: PMC6857002 DOI: 10.3389/fonc.2019.01102] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Accepted: 10/07/2019] [Indexed: 01/19/2023] Open
Abstract
Background: GOLFIG is a chemo-immunotherapy regimen established in preclinical models that combines gemcitabine + FOLFOX (fluoropyrimidine backbone coupled to oxaliplatin) poly-chemotherapy with low-dose s. c. recombinant interleukin-2 (rIL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF). Promising antitumor effects in metastatic colorectal cancer (mCRC) patients were obtained in previous phase II and III trials. Here we report the results of 15 years of follow-up. Methods: This is a multi-institutional retrospective analysis including 179 mCRC patients receiving GOLFIG regimen between June 2002 and June 2018. Sixty-two of them received the treatment as frontline (enrolled in the GOLFIG-2 phase III trial) and 117 as second/third line (49 enrolled in the GOLFIG-1 phase II trial and 68 as compassionate use). One hundred twelve patients showed a primary left side and 67 a primary right side; K/N-ras mutational status was available in 74 cases, and an activating mutation was detected in 33. Kaplan-Meier and Cox regression analyses were carried out to relate PFS and OS with different parameters. Results: Overall, we recorded a mean PFS and OS of 15.28 (95% CI: 10.36-20.20) and 24.6 (95% CI: 19.07-30.14) months, respectively, with 14 patients surviving free of progression for 10 years. This regimen, in our updated survey of the GOLFIG-2 trial, confirmed superiority over FOLFOX in terms of PFS (hazard ratio (HR) = 0.58, p = 0.006) with a trend to a longer OS (HR = 0.69, P = 0.06) in the first line. Our analysis also confirmed significant antitumor activity in pre-treated patients, reporting a mean PFS and OS of 12.55 (95% CI: 7.19-17.9) and 20.28 (95% CI: 14.4-26.13) months, respectively. Immune-related adverse events (irAEs) were recorded in 24% of the cases and were related to a longer survival (HR = 0.36; P = 0.0001). Finally, patients' outcome was not correlated to sex, sidedness, and MT-K/N-ras. Conclusions: The GOLFIG regimen is a reliable underestimated therapeutic option in pre-treated mCRC patients and offers a strong rationale to design further trials.

Abstract
The establishment of individualized chemotherapy for colorectal carcinoma based on the expression of genes involved in chemotherapeutic sensitivity or prognosis is necessary. To achieve this, the expression profiles of genes within tumors and their relationship to clinicopathological factors must be elucidated. Here, we selected 10 genes (TS, DPD, TP, FPGS, GGH, DHFR, ERCC1, TOPO-1, VEGF, and EGFR), examined differences in their mRNA expression between the upper and lower thirds of tumors by laser-captured microdissection and real-time RT-PCR (the Danenberg tumor profile), and analyzed the relationships between their expression profiles and clinicopathological factors. Interestingly, the mRNA expression of DPD, TP, and VEGF was significantly higher in the lower third than in the upper third of tumors (P = 0.044, 0.023, and 0.013, resp.). Furthermore, increased ERCC1 mRNA expression in the lower third of tumors correlated with recurrence (P = 0.049), and VEGF mRNA expression was significantly higher in cases with recurrence than in cases without recurrence, both in the upper and lower thirds of tumors (P = 0.018 and 0.036, resp.). These results implied that heterogeneity in DPD, TP, and VEGF expression may exist in colorectal carcinoma and that ERCC-1 and VEGF may be markers predicting recurrence after curative operation.

Abstract
INTRODUCTION A number of anti-EGFR monoclonal antibodies (mAbs) have been recently developed for the treatment of refractory metastatic colorectal cancer (mCRC). These mAbs, blocking ligand/receptor interactions, exert their biological activity via multiple mechanisms, including inhibition of cell cycle progression, potentiation of cell apoptosis, inhibition of angiogenesis, tumor cell invasion and metastasis and, potentially, induction of immunological effector mechanisms. AREAS COVERED Cetuximab is an anti-EGFR mAb currently used in mCRC treatment. Despite the evidence of efficacy of cetuximab in the treatment of mCRC patients, the observation of low response rates was the proof of concept of resistance to anti-EGFR mAbs treatment. An increasing number of molecular alterations have been more recently hypothesized to be involved in resistance to anti-EGFR mAbs in CRC: mutations in BRAF, NRAS and PIK3CA, loss of expression of PTEN and, now, activation of HER2 signaling through HER2 gene amplification and/or increased heregulin stimulation. EXPERT OPINION This review focuses on the development of new strategies such as combination with other agents blocking alternative escape pathways, cancer cell prioritization hyperactivating EGFR pathway, combination with immune system, development of nanotech devices to increase efficacy of antibody-based therapy and overcome the mechanisms of cancer cell resistance.

Abstract
PURPOSE An efficient adaptive immunity is critical for a longer survival in cancer. We investigated the prognostic value of tumor infiltration by CD8(+) T cells expressing the chemokine-receptor-7 (T(ccr7)) and the correlation between tumor infiltration by T(ccr7) and regulatory CD4(+)FoxP3(+) T cells (T(reg)) in 76 metastatic colorectal cancer (mCRC) patients enrolled in a phase III trial. EXPERIMENTAL DESIGN T(ccr7) and T(reg) cell infiltration in tumor samples was quantified by immunohistochemistry. The correlation among T(ccr7), T(reg) tumor infiltration, and patients' outcome was evaluated. RESULTS High T(ccr7) tumor infiltration was predictive of prolonged OS [high vs. low T(ccr7) score: median 38 months (95% CI: 24.5-51.4) vs. 20 months (95% CI: 11.4-28.5); HR = 0.48 (95% CI: 0.24-0.96); P = 0.03] and prolonged progression-free survival [PFS; high vs. low T(ccr7) score: median 12 months (95% CI: 7.7-16.2) vs. 7 months (95% CI: 5.2-8.7); HR = 0.54 (95% CI: 0.28-1.01); P = 0.01] after front-line chemotherapy. Regression analysis did not show correlation between T(ccr7) and T(reg) infiltration levels. However, the cluster of patients showing concomitant high infiltration by both T(ccr7) and T(reg) disclosed a favorable outcome [double high vs. double low tumor infiltration score: median OS = 35 months (95% CI: 20.8-49.1) vs. 17 months (95% CI: 4.6-29.3); HR = 0.32 (95% CI: 0.12-0.87); P = 0.02 and median PFS = 11 months (95% CI: 9.4-12.5) vs. 5 months (95% CI: 2.2-7.7); HR = 0.43 (95% CI: 0.17-1.06); P = 0.01]. CONCLUSIONS High T(ccr7) tumor infiltration score is a favorable prognostic factor for mCRC. Our findings underline the relevance of microenvironment-related immunologic events for patient outcome.

Combining capecitabine, oxaliplatin, and gemcitabine (XELOXGEM) for colorectal carcinoma patients pretreated with irinotecan: a multicenter phase I/II trial. Cancer Chemother Pharmacol 2011; 69:91-7. [PMID: 21607556 DOI: 10.1007/s00280-011-1668-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2011] [Accepted: 05/02/2011] [Indexed: 10/18/2022]
Abstract
PURPOSE Capecitabine plus oxaliplatin (XELOX) is an effective second-line regimen for advanced colorectal carcinoma (CRC) patients pretreated with irinotecan. Previous studies have shown supra-additive anti-tumor activity of gemcitabine (GEM) when administered with oxaliplatin. We investigated the dose, toxicity, and efficacy of a second-line XELOXGEM regimen in CRC patients pretreated with irinotecan. METHODS Patients with metastatic or recurrent CRC who failed after a first-line irinotecan-containing regimen received escalating doses of gemcitabine (600, 800, 1,000 mg/m(2) d1, d8) followed by capecitabine (1,000 mg/m(2) b.i.d d1-14) and oxaliplatin (100 mg/m(2) d1) on a 21-day cycle. RESULTS A total of 38 patients were treated. At 800 mg/m(2), two of six patients experienced dose-limiting toxicities (diarrhea and thrombocytopenia). Therefore, the clinically recommended dose was defined as 600 mg/m(2) gemcitabine (d1, d8) followed by 1,000 mg/m(2) capecitabine (b.i.d dl-14) and 100 mg/m(2) oxaliplatin (d1). The most common grade 3/4 toxicities were neutropenia (32%), thrombocytopenia (13%), anemia (11%), and peripheral neuropathy (11%). Ten (26.3%) and 23 (60.5%) patients experienced partial response and stable disease, respectively. The median progression-free survival and overall survival were 5.4 months (95% CI 3.8-6.9 months) and 17.7 months (95% CI 8.4-26.9 months), respectively. CONCLUSIONS The XELOXGEM triplet combination is an active and safe second-line regimen for advanced CRC patients pretreated with irinotecan.

Abstract
BACKGROUND To investigate whether single nucleotide polymorphisms (SNPs) in gemcitabine (GMB) metabolism genes were associated with clinical outcome in pre-treated metastatic colorectal cancer (mCRC) patients. PATIENTS AND METHODS SNPs of hCNT1, hENT1, CDA, dCTD and RRM1 genes were evaluated in 95 mCRC patients and detected using TaqMan genotyping assays. Association of genotypes with overall response rate (ORR), time to progression (TTP) and overall survival (OS) was tested by univariate and multivariate analysis. RRM1 -37A>C polymorphism was correlated with GMB IC50 value and with the RRM1 gene expression level in CRC cell lines. RESULTS The ORR was 38.9%. The median TTP and OS were 4 and 14.3 months, respectively. By multivariate analysis, patients carrying the RRM1 -37CC genotype or the CDA A-76 C-containing allele had a significantly higher likelihood of achieving a tumour response. RRM1 -37A>C polymorphism remained associated with clinical efficacy (TTP). In vitro experiments, in CRC cell lines, showed that the RRM1 A-37C genotype was associated with the levels of RRM1 expression and with GMB IC50 values. Finally, the down-regulation of RRM1 with a specific siRNA strongly influenced GMB sensitivity. CONCLUSION RRM1 -37A>C polymorphism may represent a useful biomarker to select mCRC patients most likely to benefit from GMB-based salvage therapy.

Abstract
BACKGROUND To determine the dose-limiting toxicity (DLT), maximum tolerated dose, recommended dose (RD) and preliminary evidence of activity of escalating doses of irinotecan (CPT-11) fixed-dose-rate infusional gemcitabine (FDR-GMB) and bevacizumab in pretreated metastatic colorectal cancer (mCRC) patients. Pharmacogenomic analysis was performed to investigate the association between VEGF single-nucleotide polymorphisms and clinical outcome. PATIENTS AND METHODS A total of 89 mCRC patients were recruited in a two-step study design; 28 were included in the dose-finding study and 59 in the pharmacogenomic analysis. The FDR-GMB of 1000 mg m⁻², bevacizumab 5 mg kg⁻¹ and CPT-11 doses ranging from 100 to 160 mg m⁻² were explored. The VEGF protein serum levels were quantified by EIA. Allelic discrimination was performed to genotype polymorphisms in the VEGF gene. RESULTS CPT-11 RD was 150 mg m⁻². Diarrhoea and neutropenia were the DLT. After a median follow-up of 42 months, the median time to progression (TTP) and overall survival were 5.2 and 19.9 months, respectively. VEGF levels were significantly correlated with VEGF-2578AA and VEGF-460CC genotypes, and a trend was observed with VEGF+405GG genotype. The presence of any of these genotypes correlated with a longer median TTP (8.8 vs 4.5 months, P=0.04). CONCLUSION The triplet combination tested in this study is effective and well tolerated. A possible predictive role for VEGF gene polymorphisms and baseline VEGF circulating levels is suggested.

Abstract
Antitumor immune response and chemotherapy-induced immunomodulation in colon cancer patients represented the rationale to design new strategies, like GOLFIG chemoimmunotherapy (gemcitabine, oxaliplatin, 5-fluorouracil/folinic acid, granulocyte macrophage colony-stimulating factor, and aldesleukine), that resulted a safe and very active regimen. Antitumor activity and immunity feedback to GOLFIG were strictly correlated with the best outcome observed in patients with autoimmunity signs, increase of central memory T cells, and decrease of regulatory T cells (Treg) in the peripheral blood. We thus investigated a potential correlation between the Treg tumor infiltration at diagnosis and the clinical outcome in a current randomized phase 3 trial aimed to compare the GOLFIG regimen with the standard FOLFOX chemotherapy (GOLFIG-2). An immunohistochemistry study was carried out to quantify the infiltration of Treg/FoxP3+ T lymphocytes in tumor samples of 57 patients enrolled in the GOLFIG-2 trial. Treg tumor infiltration scores were correlated with overall survival, treatment-relative survival, and progression-free survival (PFS). Higher Treg tumor infiltration scores were associated with a better prognosis in the whole series (Treg high score vs. low score: overall survival=mean 43.2 mo vs. 28.6 mo, P=0.0005) and a better outcome after treatment (Treg high score vs. low score: PFS=mean 15.8 mo vs. 8.8 mo, P=0.0009; treatment-relative survival=mean 23.1 mo vs. 18.2 mo, P=0.004). PFS was significantly longer in GOLFIG high versus all other subgroups (mean 18.1 mo vs. 9.9 mo, P=0.01). Our results suggest that a higher FoxP3+ T-lymphocyte tumor infiltration score is a favorable prognostic factor in colon cancer patients undergoing chemo or chemoimmunotherapy.

Abstract
INTRODUCTION Fluoropyrimidines with oxaliplatin or irinotecan plus bevacizumab is the standard chemotherapy combination in patients with advanced colorectal cancer (CRC). Gemcitabine acts synergistically with fluoropyrimidines to enhance the binding of thymidylate synthase and increase inhibition of DNA synthesis. The objective of this review is to evaluate the literature for evidence of efficacy and safety of fluoropyrimidine plus gemcitabine (FG) in patients with advanced CRC. METHODS Relevant studies were identified in PubMed, Ovid, Cochrane database and the American Society of Clinical Oncology abstracts using the following search terms: gemcitabine, fluorouracil, capecitabine and colorectal cancer. Only studies using the FG combination were selected. RESULTS Forty-two advanced CRC patients were evaluated in two Phase I studies and the maximum tolerated dose of gemcitabine was 900 - 1,000 mg/m(2) weekly with either bolus 5-fluorouracil (5-FU) or capecitabine. A total of 216 advanced CRC patients were evaluated in six Phase II studies. Gemcitabine (750 - 1,250 mg/m2) with either 5-FU (continuous infusion or bolus) or capecitabine was administered as first-line therapy in two studies and as third-line therapy in three studies. The range reported for overall response rate was 30 - 38.3%, median time to progression was 4 - 8.3+ months and median survival was 9.8 - 18+ months. The most commonly reported grade 3 - 4 toxicities were neutropenia, thrombocytopenia and mucositis. CONCLUSIONS Fluoropyrimidine plus gemcitabine is clinically active in patients with refractory CRC demonstrating prolonged median time to progression and acceptable toxicity only when bolus 5-FU was not used. Studies are underway to evaluate the combinations of FG with other chemotherapy or targeted agents. Meanwhile, FG may be considered for patients with advanced CRC who are refractory to primary treatment without other options or who are not eligible for clinical studies.

Abstract
PURPOSE GOLFIG chemoimmunotherapy regimen proved to be a safe and very active chemoimmunotherapy regimen in advanced colon cancer patients. We have thus investigated the immunobiological feedback to the treatment and its possible correlation with the clinical outcome of these patients. EXPERIMENTAL DESIGN This clinical and immunologic study involved 46 patients, 27 males and 19 females, enrolled in the GOLFIG-1 phase II trial who received gemcitabine (1,000 mg/m(2) on days 1 and 15), oxaliplatin (85 mg/m(2) on days 2 and 16), levofolinic acid (100 mg/m(2) on days 1, 2, 15, and 16), and 5-fluorouracil (400 mg/m(2) as a bolus, and 800 mg/m(2) as a 24-hour infusion on days 1, 2, 15, and 16) followed by s.c. granulocyte macrophage colony-stimulating factor (100 mug, on days 3-7) and interleukin 2 (0.5 x 10(6) IU twice a day on days 8-14 and 17-29). RESULTS The regimen was confirmed to be safe and very active in pretreated patients with metastatic colorectal cancer. A subgroup analysis of these patients revealed a prolonged time to progression and survival in six patients who developed late signs of autoimmunity. A multivariate analysis validated the occurrence of autoimmunity signs as an independent predictor of favorable outcome. A parallel immunologic study detected in the peripheral blood mononuclear cells of these patients a progressive increase in lymphocyte and eosinophil counts, amplification in central memory, a marked depletion of immunosuppressive regulatory T cells, and activation of colon cancer-specific cytotoxic T cells. CONCLUSIONS Our results suggest that immunity feedback to GOLFIG regimen and its antitumor activity are tightly correlated.

Abstract
GOLFIG-1 chemo-immunotherapy is a new translational anticancer regimen based on the combined use of gemcitabine, oxalipatin, levofolinic acid and infusional 5-fluorouracil together with the subcutaneous administration immunoadjuvant cytokines (GM-CSF and ultra low dose IL-2). This regimen, tested in a phase II trial, was safe and very active in patients with metastatic colorectal carcinoma and it has been shown to have powerful immunobiological activity. Treatment with the GOLFIG regimen resulted in the induction of a colon cancer specific cell mediated immune response associated with a significant reduction in the percentage of peripheral regulatory T (T(reg)) cells, a very immunosuppressive lymphocyte subset which is commonly over-represented in cancer patients. These cells are able to prevent the occurrence of autoimmunity in response to immunological stimuli, thus their malfunctioning has been associated with the occurrence of auto-immune diseases but may also be responsible for more efficient anticancer immune reaction. In this manuscript we describe a clinical case concerning a patient with metastatic colon carcinoma who responded to the GOLFIG regimen, showed symptoms of autoimmunity [Discoid Lupus Erythematosus (DLE)] and had a very long survival.

Abstract
The effects of anticancer chemotherapy on antigen-specific cytotoxic T lymphocytes (CTLs) are mostly unknown. We tested the effects of cytotoxic drugs such as 5-fluorouracil, gemcitabine, and oxaliplatin on the functional activity of antigen-specific CTL cultures derived from the peripheral blood mononuclear cells of human donors. We found that a biweekly drug-exposure of human HLA-A(*)02.01+ CTLs derived from bulk cultures led to completely different effects if occurring early (day second) or late (day thirteenth) after the in vitro stimulations with the cognate peptides. In the first case, there was a significant CTL inhibition, whereas in the second, there was a marked enhancement of the antigen-specific cytolytic activity. Results of immunocytofluorimetric studies and CTL/natural killer inhibition assays suggested that the latter effect could be related to a more selective drug-mediated inhibition of cohabitant T regulatory (reg) cells. These results were translated in an in vivo therapeutic mouse model where humanized HLA-A(*)02.01 transgenic mice inoculated with EL-4/humanized HLA-A(*)02.01 transgenic mice showed a prolonged survival and the greatest rate of cure when receiving a combined treatment with a thymidylate synthase-specific peptide vaccine and a multidrug chemotherapy regimen administered late after immunization. Tumor samples derived from this group of mice showed a reduced expression of the target thymidylate synthase antigen, a marked reduction of T(reg)s, and a noteworthy infiltration of C8+ T cells. These results may have clinical implications for the design of new translational anticancer regimens aimed at combining chemotherapy and immunotherapy.

Abstract
BACKGROUND Second-line therapy of advanced colorectal cancer (CRC) after failure of a combination of irinotecan, a fluoropyrimidine, and bevacizumab includes the use of oxaliplatin and a fluoropyrimidine. In animal models, synergistic effects of gemcitabine and platinum agents have been established. Additionally, superior antitumor activity of prolonged administration of gemcitabine compared with bolus administration has been demonstrated in vivo against murine colon tumors. PATIENTS AND METHODS A 2-stage phase II trial was developed to assess the efficacy (primary endpoint: response rate) and safety of gemcitabine 1000 mg/m(2) over 100 minutes on days 1 and 15 in combination with oxaliplatin 100 mg/m(2) over 2 hours on days 2 and 16, every 4 weeks. Patients with metastatic CRC in whom irinotecan and a fluoropyrimidine treatment had failed were enrolled. Calcium and magnesium infusion was routinely given before and after oxaliplatin administration. RESULTS Because of slow accrual as a result of oxaliplatin becoming more commonly used in first-line treatment, the trial was stopped with only 10 patients enrolled. Eight were men and 2 were women. Median age was 58.5 years (range, 47-72 years). Nine patients had an Eastern Cooperative Oncology Group performance status of 0/1. A median of 3.5 cycles was administered (range, 1-9; total, 42). Six patients had stable disease and 1 had progressive disease. Two patients had confirmed partial responses, and 1 patient had a partial response but developed necrotizing fasciitis, declined surgical treatment, and died before a confirmatory scan could be performed. The regimen was otherwise well tolerated: 1 patient developed grade 3 neutropenia. With a median follow-up of 5.5 months, 4 patients have died. The time to treatment failure was 3.7 months. CONCLUSION Despite premature study closure because of poor accrual, oxaliplatin in combination with fixed-rate infusional gemcitabine seems to be a safe and potentially effective regimen in the treatment of CRC. Further studies should be considered with the addition of targeted therapy.

Abstract
Target-based therapy has been a promising anti-cancer strategy in the preclinical setting, but its efficacy is still limited in clinical practice. The latter was probably due to the lack of identification of molecular targets in order to predict clinical response and for the existence of multiple survival compensatory downstream pathways. Therefore, the use of downstream targets could be useful in order to avoid these overcoming pathways. One of these targets is Raf-kinase. In this review we describe the structure and functions of the components of Raf-kinase family and their relevance in proliferation and survival of tumor cells. Moreover, we illustrate the signal transduction pathways regulated by Raf-kinases. The main preclinical and clinical results obtained with the use of the Raf-kinase inhibitor BAY 43-9006 or sorafenib are also described. The multi-target function of sorafenib is also explained and the disclosure of new therapeutic opportunities based on the dual inhibition of cancer proliferation and neo-angiogenesis is discussed. In conclusion, Raf-kinase appears an appealing therapeutic target, even it other preclinical and clinical studies are warranted in order to evaluate the activity of sorafenib both in monotherapy and in combination with other agents.

Abstract
PURPOSE To evaluate the efficacy and tolerance of the gemcitabine/oxaliplatin (GEMOX) combination as second-line chemotherapy for patients with advanced colorectal cancer (CRC) pretreated with an irinotecan (CPT-11)/5-fluorouracil (5-FU)/leucovorin (LV) regimen. PATIENTS AND METHODS Patients with documented disease progression during or after first-line treatment with CPT-11 and 5-FU/LV were enrolled. Gemcitabine (1,000 mg/m(2) days 1 and 8) and oxaliplatin (100 mg/m(2) day 1) were administered every 3 weeks. RESULTS Partial responses were observed in 6 of the 34 (17.7%) patients enrolled (intention-to-treat analysis; overall response rate: 17.7%; 95% confidence interval 4.8-30.5%). Eight (23.5%) patients experienced disease stabilization and 20 (59%) disease progression (tumor growth control rate = 41.2%). The median duration of response was 5.5 months, and the median time to tumor progression 2.7 months. The median overall survival was 9.1 months (1-year survival rate: 44.0%). Grade 3 neutropenia and thrombocytopenia occurred in 18 and 15% of the patients, respectively. Other severe non-hematologic toxicities were rare. CONCLUSION The interesting tumor growth control rate and the favorable toxicity profile of the GEMOX regimen in pretreated patients with advanced CRC strongly suggest that this regimen may provide an alternative therapeutic option for this group of patients.

Abstract
Gemcitabine, oxaliplatin, leucovorin, and 5-fluorouracil (GOLF) is a novel multidrug regimen inducing high levels of necrosis and apoptosis in colon carcinoma cells. This regimen is also able to promote a process of Ag remodeling including up-regulation of immunotherapy targets like carcinoembryonic Ag (CEA), thymidylate synthase (TS). We have conducted a preclinical study aimed to investigate whether these drug-induced modifications would also enhance colon cancer cell immunogenicity. Several CTL lines were thus generated by in vitro stimulating human HLA-A(*)02.01(+) PBMCs, from normal donors and colon cancer patients, with autologous dendritic cells cross-primed with cell lysates of colon cancer cells untreated, irradiated, or previously exposed to different drug treatments including the GOLF regimen. Class I HLA-restricted cytolytic activity of these CTL lines was tested against colon cancer cells and CEA and TS gene transfected target cells. These experiments revealed that CTLs sensitized with GOLF-treated cancer cells were much more effective than those sensitized with the untreated colon carcinoma cells or those exposed to the other treatments. CTL lines sensitized against the GOLF-treated colon cancer cells, also expressed a greater percentage of T-lymphocyte precursors able to recognize TS- and CEA-derived peptides. These results suggest that GOLF regimen is a powerful antitumor and immunomodulating regimen that can make the tumor cells a suitable means to induce an Ag-specific CTL response. These results suggest that a rationale combination of GOLF chemotherapy with cytokine-based immunotherapy could generate a chemotherapy-modulated Ag-specific T-lymphocyte response in cancer patients able to destroy the residual disease survived to the cytotoxic drugs.

Abstract
PURPOSE Tumor cell killing by anticancer drugs may be supported by their immuno- and pharmacologic effects. Chemotherapy is in fact able to (A) upregulate tumor-associated antigen expression, including carcinoembryonic antigen (CEA) or other target molecules such as thymidylate synthase (TS); and (B) downregulate tumor cell resistance to the death signals induced by tumor antigen-specific cytotoxic T lymphocytes. This provides the rationale for combining chemo- and immunotherapy. MATERIALS AND METHODS We describe the results of a translational phase II trial designed to evaluate the toxicity, antitumor activity and immunologic effects of gemcitabine + FOLFOX-4 (oxaliplatin, fluorouracil, and folinic acid) polychemotherapy followed by the subcutaneous administration of granulocyte macrophage colony-stimulating factor and low-dose interleukin-2 in colorectal carcinoma patients. The study involved 29 patients (16 males and 13 females with a mean age of 69 years), 21 of whom had received a previous line of treatment, and 19 had liver involvement. RESULTS The treatment was well tolerated and induced very high objective response (68.9%) and disease control rates (96.5%), with an average time to progression of 12.5 months. An immunologic study of peripheral blood mononuclear cells (PBMCs) taken from 20 patients showed an enhanced proliferative response to colon carcinoma antigen and a significant reduction in suppressive regulatory T lymphocytes (CD4+CD25T-reg+). A cytofluorimetric study of the PBMCs of five HLA-A(*)02.01+ patients who achieved an objective response showed an increased frequency of cytolytic T lymphocyte precursors specific for known CEA- and TS-derived epitopes. CONCLUSION The results show that our regimen has strong immunologic and antitumor activity in colorectal cancer patients and deserves to be investigated in phase III trials.

Abstract
BACKGROUND AND AIMS oxaliplatin in combination with folinic acid (FA) and infusional 5-fluorouracil (5-FU) has shown significant anti-tumor activity in gastric cancer patients (FOLFOX). Previous studies have shown that gemcitabine (GEM), a new fluorinated anti-metabolite, enhances the individual anti-tumor activity of either 5-FU or oxaliplatin. We have therefore designed a multi-center phase II trial in order to test a novel GEM+FOLFOX-4 regimen in patients with metastatic gastric cancer. METHODS we enrolled 36 patients, 28 males and 8 females, with an average age of 64.4 years (range 37-78), who received bi-weekly treatment with GEM (1,000 mg/m2 on day 1), levo-FA (100 mg/m2 on days 1 and 2), a 5-FU (400 mg/m2) bolus injection followed by 22-h continuous infusion (800 mg/m2) on days 1 and 2, and oxaliplatin 85 mg/m2 in a 4-6 h intravenous (i.v.) infusion before the second FUFA administration on day 2. RESULTS the most frequent side effect was grade 1-2 hematological toxicity and late sensorial neurotoxicity. Two patients developed hypersensitivity to oxaliplatin while another developed an aseptic eosinophilic pneumonitis. Two patients refused to continue the treatment after two cycles of chemotherapy and were lost at the follow-up. Among the remaining 34 patients four achieved a complete response, 15 a partial response, 12 had a stable disease and three progressed. CONCLUSIONS these results may grant the rationale to evaluate this multi-drug combination in randomized phase III trials in advanced gastric cancer.

Abstract
Cisplatin, a widely used chemotherapeutic agent, has been implicated in the induction of secondary tumors in cancer patients. This drug is presumed to be mutagenic because of error-prone translesion synthesis of cisplatin adducts in DNA. Oxaliplatin is effective in cisplatin-resistant tumors, but its mutagenicity in humans has not been reported. The polymerases involved in bypass of cisplatin and oxaliplatin adducts in vivo are not known. DNA polymerase eta is the most efficient polymerase for bypassing platinum adducts in vitro. We evaluated the role of polymerase eta in translesion synthesis past platinum adducts by determining cytotoxicity and induced mutation frequencies at the hypoxanthine guanine phosphoribosyltransferase (HPRT) locus in diploid human fibroblasts. Normal human fibroblasts (NHF1) were compared with xeroderma pigmentosum variant (XPV) cells (polymerase eta-null) after treatment with cisplatin. In addition, XPV cells complemented for polymerase eta expression were compared with the isogenic cells carrying the empty expression vector. Cytotoxicity and induced mutagenicity experiments were measured in parallel in UVC-irradiated fibroblasts. We found that equitoxic doses of cisplatin induced mutations in fibroblasts lacking polymerase eta at frequencies 2- to 2.5-fold higher than in fibroblasts with either normal or high levels of polymerase eta. These results indicate that polymerase eta is involved in error-free translesion synthesis past some cisplatin adducts. We also found that per lethal event, cisplatin was less mutagenic than UVC. Treatment with a wide range of cytotoxic doses of oxaliplatin did not induce mutations above background levels in cells either expressing or lacking polymerase eta, suggesting that oxaliplatin is nonmutagenic in human fibroblasts.
