Abstract
Caffeic acid phenethyl ester (CAPE), a main active component of propolis and a flavonoid, is one of the natural products that has attracted attention in recent years. CAPE, which has many properties such as anti-cancer, anti-inflammatory, antioxidant, antibacterial and anti-fungal, has shown many pharmacological potentials, including protective effects on multiple organs. Interestingly, molecular docking studies showed the possibility of binding of CAPE with replication enzyme. In addition, it was seen that in order to increase the binding security of the replication enzyme and CAPE, modifications can be made at three sites on the CAPE molecule, which leads to the possibility of the compound working more powerfully and usefully to prevent the proliferation of cancer cells and reduce its rate. Also, it was found that CAPE has an inhibitory effect against the main protease enzyme and may be effective in the treatment of SARS-CoV-2. This review covers in detail the importance of CAPE in alternative medicine, its pharmacological value, its potential as a cancer anti-proliferative agent, its dual role in radioprotection and radiosensitization, and its use against coronavirus disease 2019 (COVID-19).

Abstract
Abstract
Iron and ferritin have been used in human medicine for years to reveal the presence of inflammation. However, studies evaluating these parameters, especially in respiratory system diseases, are quite rare in veterinary medicine. We aimed to test the usability of serum Fe and Fe-related parameters [total iron-binding capacity (TIBC), unsaturated iron-binding capacity (UIBC) and transferrin saturation (TS) levels] as inflammatory and diagnostic biomarkers in calves with bovine respiratory disease complex (BRDC). To mark inflammation, some selected acute-phase proteins including serum ferritin and transferrin levels were measured because of their close relationship with iron metabolism. The material of this study consisted of 15 calves, aged 1-3 months with BRDC (Group I) and 10 healthy calves aged 1-3 months (Group II) based on the presence of respiratory clinical findings. Serum Fe, TIBC and TS levels were low and ferritin levels were high in Group I (P ≤ 0.001). The BRDC group was separated into two subgroups based on PCR results, namely Virus+ (n=9) and Virus- (n=6). The calves in the Virus+ group had significantly lower levels of Fe (P=0.001) and significantly higher values of ferritin (P=0.002), compared to the healthy group. On the basis of inter-group comparison and ROC analysis, we concluded that Fe (primarily), ferritin, TIBC and TS levels can be used as inflammatory biomarkers and possible diagnostic markers in the BRDC as useful, practical, inexpensive substitutes. As a suggestion, these parameters which are believed to play a role in the pathogenesis of the disease, can be used as potential prognostic biomarkers in studies involving treatment.

Abstract
Widely consumed worldwide, Nigella sativa (NS) is a medicinal herb commonly used in various alternative medicine systems such as Unani and Tibb, Ayurveda, and Siddha. Recommended for regular use in Tibb-e-Nabwi (Prophetic Medicine), NS is considered one of the most notable forms of healing medicine in Islamic literature. Thymoquinone (TQ), the main component of the essential oil of NS, has been reported to have many properties such as antioxidant, anti-inflammatory, antiviral, and antineoplastic. Its chemical structure indicates antiviral potential against many viruses, including the hepatitis C virus, human immunodeficiency virus, and other coronavirus diseases. Interestingly, molecular docking studies have demonstrated that TQ can potentially inhibit the development of the coronavirus disease 2019 (COVID-19) by binding to the receptor site on the transmembrane serine proteinase 2 (the activator enzyme that attaches the virus to the cell). In addition, TQ has been shown to be effective against cancer cells due to its inhibitory effect by binding to the different regions of MDM2, according to the proposed molecular docking study. Detailed in this review is the origin of TQ, its significance in alternative medicine, pharmacological value, potential as a cancer anti-proliferative agent, use against the coronavirus disease 2019 (COVID-19), and treatment of other diseases.

Abstract
Introduction C-reactive protein (CRP) is an acute-phase reactant used as a general marker for inflammation. Isolated levels have been associated with prostate cancer development, prostate-specific antigen (PSA), Gleason score, and treatment response. We seek to establish whether CRP levels reflect inflammation caused by prostate cancer by comparing levels at various points of time before, during, and after therapy. Materials and methods A total of 209 patients had a complete blood count (CBC), PSA, and CRP taken at up to four different time points. Labs were performed up to one week prior to androgen ablation via leuprolide injection (pre-AA), up to one week prior to radiotherapy (RT) (pre-RT), within one week of RT completion (post-RT), and three months following RT completion (FU [follow-up]). Results Significant relationships were found between CRP and WBC pre-AA (p-value=0.0050), pre-RT (p-value=0.0170), and post-RT (p-value=0.0113), but not at FU (p=.096). CRP had no significant relationship with PSA or lymphocytes at any time points. PSA was significantly affected by androgen ablation but lymphocytes, WBCs, and CRP were not. No CRP levels were associated with risk groups or FU-PSA. Lymphatic radiation fields significantly decreased WBCs and lymphocytes but not CRP. PSA, WBC, and lymphocytes all significantly decreased from pre-RT to post-RT, followed by a significant recovery. CRP did not significantly change during any of these periods and was not significantly related to changes in PSA, WBCs, or lymphocytes. Conclusion CRP is not a sensitive marker of the acute inflammatory effects of non-metastatic prostate cancer and treatment response with androgen ablation or radiation therapy.

Abstract
The accepted generic multiple-parameter and early-response biodosimetry and dosimetry assessment approach for suspected high-dose radiation (i.e. life-threatening) exposure includes measuring radioactivity associated with the exposed individual (if appropriate); observing and recording prodromal signs/symptoms; obtaining serial complete blood counts with white-blood-cell differential; sampling blood for the chromosome-aberration cytogenetic bioassay using the 'gold standard' dicentric assay (premature chromosome condensation assay for exposures >5 Gy photon acute doses equivalent), measurement of proteomic biomarkers and gene expression assays for dose assessment; bioassay sampling, if appropriate, to determine radioactive internal contamination; physical dose reconstruction, and using other available opportunistic dosimetry approaches. Biodosimetry and dosimetry resources are identified and should be setup in advance along with agreements to access additional national, regional, and international resources. This multifaceted capability needs to be integrated into a biodosimetry/dosimetry 'concept of operations' for use in a radiological emergency. The combined use of traditional biological-, clinical-, and physical-dosimetry should be use in an integrated approach to provide: (a) early-phase diagnostics to guide the development of initial medical-management strategy, and (b) intermediate and definitive assessment of radiation dose and injury. Use of early-phase (a) clinical signs and symptoms, (b) blood chemistry biomarkers, and (c) triage cytogenetics shows diagnostic utility to predict acute radiation injury severity.

Abstract
Lung cancer has high morbidity and mortality and small cell lung cancer (SCLC) is a highly invasive malignant tumor with a very unfavorable survival rate. Early diagnosis and treatment can result in better prognosis for the SCLC patients but current diagnostic methods are either invasive or incapable for large-scale screen. Therefore, discovering biomarkers for early diagnosis of SCLC is of importance. In this work, we covalently coupled Concanavalin A (ConA) to functionalized magnetic nanoparticles to obtain magnetic ConA-nanoparticles (ConA-NPs) for the enrichment of glycosylated proteins. We then purified glycosylated proteins in 36 urine samples from 9 healthy controls, 9 SCLC patients, 9 lung adenocarcinoma (LUAD) patients, and 9 lung squamous cell carcinoma (LUSC) patients. The purified glycosylated proteins were digested and analyzed by LC-MS/MS for identification and quantification. Among the 398 identified proteins, 20, 15, and 1 glycosylated protein(s), respectively, were upregulated in the urine of SCLC, LUAD, and LUSC patients. Immunoblotting experiments further demonstrated that cathepsin C and transferrin were significantly upregulated in the ConA-NP purified urine of SCLC patients. This work suggests that glycosylated cathepsin C and transferrin might be able to serve as potential biomarkers for the noninvasive diagnosis of SCLC patients.

Abstract
INTRODUCTION Anastomotic fistula is the most fearsome complication following colorectal surgery. Numerous studies have demonstrated the interest of postoperative CRP assay as an early diagnostic marker. Must the critical threshold for biological inflammatory markers remain the same, whether resection be colic or rectal? PATIENTS AND METHOD This is a study based on a cohort constituted between 2011 and 2014, including 497 patients with planned colorectal resection. C-reactive protein and pro-calcitonin were measured daily from day before surgery to D4. All postoperative intra-abdominal complications were considered as an anastomotic fistula. Detection thresholds were calculated from the area under the ROC curve. RESULTS An intra-abdominal septic complication occurred in 16.9% of the patients having undergone rectal resection vs. 9.9% of those having had colectomy (P=0.03). In the absence of complications there was no significant difference between the two groups in terms of postoperative inflammatory response as determined by either CRP or PCT assay. Following rectal resection, optimal area under the curve (AUC=0.87) corresponds to CRP on D4 for a threshold of 100mg/L: sensitivity 83.3%, NPV 95.3%. For colons with the same CRP at 100mg/L (AUC=0.71): sensitivity 63.6%, NPV 93.9%. CONCLUSION Notwithstanding riskier surgery, the detection threshold for an anastomotic fistula following rectal surgery remains the same: CRP>100mg/L at D4.

Abstract
In this review, we discuss the interaction between cancer and markers of inflammation (such as levels of inflammatory cells and proteins) in the circulation, and the potential benefits of routinely monitoring these markers in peripheral blood measurement assays. Next, we discuss the prognostic value and limitations of using inflammatory markers such as neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios and C-reactive protein measurements. Furthermore, the review discusses the benefits of combining multiple types of measurements and longitudinal tracking to improve staging and prognosis prediction of patients with cancer, and the ability of novel in silico frameworks to leverage this high-dimensional data.

Abstract
Ceruloplasmin and transferrin are proteins which play a potential role in the process of breast cancer development. These molecules contain Cu2+ (ceruloplasmin) or Fe3+ ions (transferrin) and thus constitute paramagnetic centers, which can be studied using electron paramagnetic resonance method. The aim of the study was to determine how paramagnetic centers in whole blood of breast cancer patients change under the influence of radiation therapy. Samples of whole blood were taken from 17 women with breast cancer treated with radiotherapy. The measurements were carried out at 170 K using X-band electron paramagnetic resonance (EPR) spectrometer Bruker EMX-10. Two distinct EPR lines, derived from high-spin Fe3+ in transferrin and Cu2+ from ceruloplasmin, were revealed in all frozen samples. The amplitude and integrated intensity of the EPR signal from Cu2+ in ceruloplasmin significantly decreased in all patients after the delivery of the radiation fraction. When comparing the integral intensity of the signal from Fe3+ in transferrin, three different situations were identified which are patient specific: a significant increase, an insignificant change, or a significant decrease after the irradiation. A decreased level of Cu2+ from ceruloplasmin in patients after radiotherapy means a low level of ceruloplasmin in the plasma or an increased content of reduced Cu+ ions. Differences in the integrated intensity of the EPR signal from transferrin translate directly into the amount of bound iron. The observed changes could indicate how well the organism fights against cancer and how easily it adapts to the situation of biochemical stress.

Abstract
Multiple hematological biomarkers (i.e. complete blood counts and serum chemistry parameters) were used in a multivariate linear-regression fit to create predictive algorithms for estimating the severity of hematopoietic acute radiation syndrome (H-ARS) using two different species (i.e. Göttingen Minipig and non-human primate (NHP) (Macacca mulatta)). Biomarker data were analyzed prior to irradiation and between 1-60 days (minipig) and 1-30 days (NHP) after irradiation exposures of 1.6-3.5 Gy (minipig) and 6.5 Gy (NHP) 60Co gamma ray doses at 0.5-0.6 Gy min-1 and 0.4 Gy min-1, respectively. Fitted radiation risk and injury categorization (RRIC) values and RRIC prediction percent accuracies were compared between the two models. Both models estimated H-ARS severity with over 80% overall predictive power and with receiver operating characteristic curve area values of 0.884 and 0.825. These results based on two animal radiation models support the concept for the use of a hematopoietic-based algorithm for predicting the risk of H-ARS in humans.

Abstract
Anti-cancer host defense mechanisms are traditionally considered to consist of tumor suppressor genes and immune surveillance by cells of the innate and adaptive immune systems. However, there is mounting evidence that components of the acute phase protein response (APPR), and, in particular, certain cationic host defense peptides (HDPs), also contribute to anti-cancer host defense. In a number of in vitro studies, certain HDPs have been shown to be cytotoxic to tumor cells either directly through cancer cell membrane destabilization and lysis or through the initiation of apoptosis in the cancer cell. In addition, many cancer cells elaborate the pro-inflammatory cytokine interleukin-6, which in turn produces an APPR that involves the release of HDPs. It is therefore possible that the release of pro-inflammatory cytokines by cancer cells initiates a poorly understood anti-tumor response by the host that involves HDP induction. We hypothesize that the APPR may form an important anti-cancer host defense response. This may be an important consideration in light of cancer treatments designed to decrease systemic inflammation. Blunting of the anti-cancer effect of the APPR may also contribute to the increased cancer rates seen in chronic immunosuppressive states.

C-Reactive Protein Is an Important Biomarker for Prognosis Tumor Recurrence and Treatment Response in Adult Solid Tumors: A Systematic Review. PLoS One 2015; 10:e0143080. [PMID: 26717416 PMCID: PMC4705106 DOI: 10.1371/journal.pone.0143080] [Citation(s) in RCA: 174] [Impact Index Per Article: 19.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Accepted: 10/30/2015] [Indexed: 12/14/2022] Open
Abstract
PURPOSE A systematic literature review was done to determine the relationship between elevated CRP and prognosis in people with solid tumors. C-reactive protein (CRP) is a serum acute phase reactant and a well-established inflammatory marker. We also examined the role of CRP to predict treatment response and tumor recurrence. METHODS MeSH (Medical Subject Heading) terms were used to search multiple electronic databases (PubMed, EMBASE, Web of Science, SCOPUS, EBM-Cochrane). Two independent reviewers selected research papers. We also included a quality Assessment (QA) score. Reports with QA scores <50% were excluded. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology was utilized for this review (S1 PRISMA Checklist). RESULTS 271 articles were identified for final review. There were 45% prospective studies and 52% retrospective. 264 had intermediate QA score (≥50% but <80%); Seven were adequate (80% -100%); A high CRP was predictive of prognosis in 90% (245/271) of studies-80% of the 245 studies by multivariate analysis, 20% by univariate analysis. Many (52%) of the articles were about gastrointestinal malignancies (GI) or kidney malignancies. A high CRP was prognostic in 90% (127 of 141) of the reports in those groups of tumors. CRP was also prognostic in most reports in other solid tumors primary sites. CONCLUSIONS A high CRP was associated with higher mortality in 90% of reports in people with solid tumors primary sites. This was particularly notable in GI malignancies and kidney malignancies. In other solid tumors (lung, pancreas, hepatocellular cancer, and bladder) an elevated CRP also predicted prognosis. In addition there is also evidence to support the use of CRP to help decide treatment response and identify tumor recurrence. Better designed large scale studies should be conducted to examine these issues more comprehensively.

Abstract
Although the basic structure of the gastrointestinal tract (GIT) is similar across species, there are significant differences in the anatomy, physiology, and biochemistry between humans and laboratory animals, which should be taken into account when conducting a gastrointestinal (GI) assessment. Historically, the percentage of cases of drug attrition associated with GI-related adverse effects is small; however, this incidence has increased over the last few years. Drug-related GI effects are very diverse, usually functional in nature, and not limited to a single pharmacological class. The most common GI signs are nausea and vomiting, diarrhea, constipation, and gastric ulceration. Despite being generally not life-threatening, they can greatly affect patient compliance and quality of life. There is therefore a real need for improved and/or more extensive GI screening of candidate drugs in preclinical development, which may help to better predict clinical effects. Models to identify drug effects on GI function cover GI motility, nausea and emesis liability, secretory function (mainly gastric secretion), and absorption aspects. Both in vitro and in vivo assessments are described in this chapter. Drug-induced effects on GI function can be assessed in stand-alone safety pharmacology studies or as endpoints integrated into toxicology studies. In silico approaches are also being developed, such as the gut-on-a-chip model, but await further optimization and validation before routine use in drug development. GI injuries are still in their infancy with regard to biomarkers, probably due to their greater diversity. Nevertheless, several potential blood, stool, and breath biomarkers have been investigated. However, additional validation studies are necessary to assess the relevance of these biomarkers and their predictive value for GI injuries.

Abstract
BACKGROUND The primary objective of the study was to identify early hematologic changes predictive for radiotherapy (RT)-associated genitourinary and gastrointestinal toxicity. METHODS In a group of 91 prostate cancer patients presenting for primary (n = 51) or postoperative (n = 40) curative RT, blood samples (blood count, acute phase proteins, and cytokines) were analyzed before (T1), three times during (T2-T4), and 6-8 weeks after (T5) radiotherapy. Before RT (baseline), on the last day (acute toxicity), a median of 2 months and 16 months (late toxicity) after RT, patients responded to a validated questionnaire (Expanded Prostate Cancer Index Composite). Acute score changes > 20 points and late changes > 10 points were considered clinically relevant. RESULTS Radiotherapy resulted in significant changes of hematologic parameters, with the largest effect on lymphocytes (mean decrease of 31-45 %) and significant dependence on target volume. C-reactive protein (CRP) elevation > 5 mg/l and hemoglobin level decrease ≥ 5 G/1 at T2 were found to be independently predictive for acute urinary toxicity (p < 0.01, respectively). CRP elevation was predominantly detected in primary prostate RT (p = 0.02). Early lymphocyte level elevation ≥ 0.3G/l at T2 was protective against late urinary and bowel toxicity (p = 0.02, respectively). Other significant predictive factors for late bowel toxicity were decreasing hemoglobin levels (cut-off ≥ 5 G/l) at T2 (p = 0.04); changes of TNF-α (tumor necrosis factor; p = 0.03) and ferritin levels (p = 0.02) at T5. All patients with late bowel toxicity had interleukin (IL)-6 levels < 1.5 ng/l at T2 (63 % without; p = 0.01). CONCLUSION Early hematologic changes during prostate cancer radiotherapy are predictive for late urinary and bowel toxicity.

Abstract
Iron and oxygen share a delicate partnership since both are indispensable for survival, but if the partnership becomes inadequate, this may rapidly terminate life. Virtually all cell components are directly or indirectly affected by cellular iron metabolism, which represents a complex, redox-based machinery that is controlled by, and essential to, metabolic requirements. Under conditions of increased oxidative stress—i.e., enhanced formation of reactive oxygen species (ROS)—however, this machinery may turn into a potential threat, the continued requirement for iron promoting adverse reactions such as the iron/H2O2-based formation of hydroxyl radicals, which exacerbate the initial pro-oxidant condition. This review will discuss the multifaceted homeodynamics of cellular iron management under normal conditions as well as in the context of oxidative stress.

Abstract
Excess iron is tightly associated with tumorigenesis in multiple human cancer types through a variety of mechanisms including catalyzing the formation of mutagenic hydroxyl radicals, regulating DNA replication, repair and cell cycle progression, affecting signal transduction in cancer cells, and acting as an essential nutrient for proliferating tumor cells. Thus, multiple therapeutic strategies based on iron deprivation have been developed in cancer therapy. During the past few years, our understanding of genetic association and molecular mechanisms between iron and tumorigenesis has expanded enormously. In this review, we briefly summarize iron homeostasis in mammals, and discuss recent progresses in understanding the aberrant iron metabolism in numerous cancer types, with a focus on studies revealing altered signal transduction in cancer cells.

Abstract
Development and validation of early-response radiation injury biomarkers are critical for effective triage and medical management of irradiated individuals. Plasma protein and haematological profiles were evaluated using multivariate linear-regression analysis to provide dose-response calibration curves for photon-radiation dose assessment in 30 rhesus macaques total-body-irradiated to 1-8.5 Gy with (60)Co gamma rays (0.55 Gy min(-1)). Equations for radiation dose received were established based on different combinations of protein biomarkers [i.e. C-reactive protein (CRP), serum amyloid A (SAA), interleukin 6 (IL-6) and Flt3 Ligand (Flt3L)] at samples collection time-points 6 h, 1, 2, 3, 4 and 7 d post-total-body irradiation. Dynamic changes in the levels of CRP, SAA, IL-6 and Flt3L may function as prognostic indicators of the time course and severity of acute radiation sickness (ARS). The combination of protein biomarkers provides greater accuracy for early radiation assessment than any one biomarker alone.

Abstract
The minipig is emerging as a potential alternative non-rodent animal model. Several biological markers (e.g., blood counts, laboratory parameters, and clinical signs) have been proposed for rapid triage of radiation victims. Here, the authors focus on the significance of bio-indicators for prediction of survivors after irradiation and compare it with human data; the relationship between these biomarkers and radiation dose is not part of this study. Male Göttingen minipigs (age 4-5 mo, weight 9-10 kg) were irradiated (or sham-irradiated) bilaterally with gamma-photons (⁶⁰Co, 0.5-0.6 Gy min⁻¹) in the dose range of 1.6-12 Gy. Peripheral blood cell counts, laboratory parameters, and clinical symptoms were collected up to 10 d after irradiation and analyzed using logistic regression analysis and calculating ROC curves. In moribund pigs, parameters such as decreased lymphocyte/granulocyte counts, increased C-reactive protein, alkaline phosphatase values, as well as increased citrulline values and body temperature, significantly (p < 0.002 up to p < 0.0001) discriminated non-survivors from survivors with high precision (ROC > 0.8). However, most predictive within the first 3 d after exposure was a combination of decreased lymphocyte counts and increased body temperature observed as early as 3 h after radiation exposure (ROC: 0.93-0.96, p < 0.0001). Sham-irradiated animals (corresponding to "worried wells") could be easily discriminated from dying pigs, thus pointing to the diagnostic significance of this analysis. These data corroborate with earlier findings performed on human radiation victims suffering from severe hematological syndrome and provide further evidence for the suitability of the minipig model as a potential alternative non-rodent animal model.

Abstract
Nuclear accidents or terrorist attacks could expose large numbers of people to ionizing radiation. Early biomarkers of radiation injury will be critical for triage, treatment, and follow-up of such individuals. The authors evaluated the utility of multiple blood biomarkers for early-response assessment of radiation exposure using a murine (CD2F1, males) total-body irradiation (TBI) model exposed to ⁶⁰Co γ rays (0.6 Gy min⁻¹) over a broad dose range (0-14 Gy) and timepoints (4 h-5 d). Results demonstrate: 1) dose-dependent changes in hematopoietic cytokines: Flt-3 ligand (Flt3L), interleukin 6 (IL-6), granulocyte colony stimulating factor (G-CSF), thrombopoietin (TPO), erythropoietin (EPO), and acute phase protein serum amyloid A (SAA); 2) dose-dependent changes in blood cell counts: lymphocytes, neutrophils, platelets, and ratio of neutrophils to lymphocytes; 3) protein results coupled with peripheral blood cell counts established very successful separation of groups irradiated to different doses; and 4) enhanced separation of dose was observed as the number of biomarkers increased. Results show that the dynamic changes in the levels of SAA, IL-6, G-CSF, and Flt3L reflect the time course and severity of acute radiation syndrome (ARS) and may function as prognostic indicators of ARS outcome. These results also demonstrate proof-in-concept that plasma proteins show promise as a complimentary approach to conventional biodosimetry for early assessment of radiation exposures and, coupled with peripheral blood cell counts, provide early diagnostic information to manage radiation casualty incidents effectively, closing a gap in capabilities to rapidly and effectively assess radiation exposure early, especially needed in case of a mass-casualty radiological incident.

Abstract
Iron is essential for life and is involved in numerous metabolic processes including cell growth and proliferation. However, excess iron in the body raises the risk of developing cancer due to its capacity to engage in redox cycling and free radical production. Therefore, iron can contribute to both carcinogenesis and tumor growth. Both epidemiologic and laboratory studies have demonstrated that the effects of iron overload are associated with the tumorigenesis of lung cancer and growth of lung cancer cells. In particular, the discovery of hepcidin and several iron transporters in the past decade may warrant reconsideration of the role of iron in carcinogenesis and tumor cell proliferation in lung cancer. Pathways of iron uptake, storage, efflux, and regulation are all disturbed in cancer, suggesting that reprogramming of iron metabolism is a critical aspect of tumor cell survival. Although these pathways in lung cancer have been identified and extensively studied, many issues on the metabolic processes of iron in lung cancer cells have not been addressed. Targeting metabolic pathways of iron may provide new tools for lung cancer prognosis and therapy.

A nonhuman primate model of human radiation-induced venocclusive liver disease and hepatocyte injury. Int J Radiat Oncol Biol Phys 2013; 88:404-411.

Abstract
BACKGROUND Human liver has an unusual sensitivity to radiation that limits its use in cancer therapy or in preconditioning for hepatocyte transplantation. Because the characteristic veno-occlusive lesions of radiation-induced liver disease do not occur in rodents, there has been no experimental model to investigate the limits of safe radiation therapy or explore the pathogenesis of hepatic veno-occlusive disease. METHODS AND MATERIALS We performed a dose-escalation study in a primate, the cynomolgus monkey, using hypofractionated stereotactic body radiotherapy in 13 animals. RESULTS At doses ≥40 Gy, animals developed a systemic syndrome resembling human radiation-induced liver disease, consisting of decreased albumin, elevated alkaline phosphatase, loss of appetite, ascites, and normal bilirubin. Higher radiation doses were lethal, causing severe disease that required euthanasia approximately 10 weeks after radiation. Even at lower doses in which radiation-induced liver disease was mild or nonexistent, latent and significant injury to hepatocytes was demonstrated by asialoglycoprotein-mediated functional imaging. These monkeys developed hepatic failure with encephalopathy when they received parenteral nutrition containing high concentrations of glucose. Histologically, livers showed central obstruction via an unusual intimal swelling that progressed to central fibrosis. CONCLUSIONS The cynomolgus monkey, as the first animal model of human veno-occlusive radiation-induced liver disease, provides a resource for characterizing the early changes and pathogenesis of venocclusion, for establishing nonlethal therapeutic dosages, and for examining experimental therapies to minimize radiation injury.

Preoperative radiotherapy does not alter pre- and early postoperative serum C-reactive protein and albumin concentrations in colorectal cancer patients. Contemp Oncol (Pozn) 2013; 17:161-4.

Abstract
Aim of the study We aimed to assess the alterations of serum C-reactive protein (CRP) and albumin levels in colorectal cancer patients who underwent preoperative radio(chemo)therapy and those who did not. Material and methods The determinations of albumin and CRP were performed before and at 2, 3, 5 and 7 days after surgery in 60 colorectal cancer patients. 25 healthy subjects served as a reference group. For each patient the modified Glasgow Prognostic Score (mGPS) was calculated. Results On the operation day CRP and albumin concentrations were not different in preoperatively treated or radiotherapy naïve patients. On postoperative day 2, 3, 5 and 7 no significant differences were observed between the two groups, with the only exception for albumin concentration, which was significantly higher on postoperative days 2 and 7 in the radiation naïve group. In all patients perioperative alterations of serum CRP level were significant at all time points (preoperatively vs. day 2, day 2 vs. day 3, day 3 vs. day 5, day 5 vs. day 7). The albumin decrease from the preoperative day to postoperative day 2 was significant, as was its increase from postoperative day 3 to 5. Conclusions We have seen no differences in the CRP and albumin concentrations in preoperatively irradiated versus non-irradiated colorectal cancer patients on the day of surgery and on postoperative days 2, 3, 5 and 7. There were, however, significant concentration changes in the value of these two serum markers from preoperatively to postoperative day 2 and over the following postoperative week, but presumably related to the surgical trauma, not the neoadjuvant treatment.

Abstract
Acute graft-versus-host-disease (aGvHD) is the major cause of non-relapse mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Recently, diagnostic biomarkers for aGvHD have been shown to play important roles in evaluating disease status and mortality risk after allo-HSCT. To identify plasma biomarkers for aGvHD with high sensitivity and specificity, a quantitative proteomic approach using 8-plex isobaric tags for relative and absolute quantitation (8-plex iTRAQ) was employed to screen differentially expressed proteins in peripheral blood before and after the onset of aGvHD. Four target proteins, ceruloplasmin (CP), myeloperoxidase (MPO), complement factor H (CFH), and alpha-1-acid glycoprotein (AGP), were chosen for preliminary validation with enzyme linked immunosorbent assay (ELISA) in 20 paired samples at both the time of diagnosis of aGvHD and the time of complete response. The most promising candidate, ceruloplasmin, was further validated at fixed time points after allo-HSCT and during aGvHD. The plasma ceruloplasmin levels were significantly increased during the period of aGvHD onset and were markedly decreased as aGvHD resolved. The plasma ceruloplasmin levels at different time points post-transplant in the aGvHD (+) group were significantly higher than those in the aGvHD (-) group (p<0.001). The elevation of ceruloplasmin level in patients with active aGvHD was independent of infection status. Patients whose ceruloplasmin levels were elevated above 670 μg/ml at 7, 14 and 21 days after allo-HSCT had a remarkably increased probability of subsequently developing aGvHD. In conclusion, our results suggest that plasma ceruloplasmin is a potential plasma biomarker of aGvHD, and it also has prognostic value for risk-adapted prophylaxis during the consecutive time points monitored in the first month after allo-HSCT.

Abstract
Background: The aim of this study was to investigate the possible protective role of antioxidant treatment with ellagic acid (EA) on lung injury after intestinal ischemia-reperfusion (I/R) injury using biochemical and histopatological approaches. Materials and Methods: Forty rats were divided into four groups as control, control + EA, I/R, and I/R + EA. The control and control + EA groups were also anesthetized and subjected to laparotomy, but without clamp application. The control + EA and I/R + EA groups were given EA (85 mg/kg) orally prior to experiment. The I/R and I/R + EA groups underwent 30 minutes of intestinal ischemia and 1 hour of reperfusion. In all groups, serum total antioxidant capacity (TAC) and malondialdehyde (MDA) levels were determined. TAC, total oxidative status (TOS), and oxidative stress index (OSI) in lung tissue were measured. Lung tissue histopathology was also evaluated by light microscopy. Results: TAC levels were higher in control, EA, and I/R + EA groups while TOS, OSI, and MDA levels were lower in these groups compared with I/R group. Serum MDA levels were significantly higher in I/R + EA group than that of control group. Lung tissue TAC levels were lower in I/R + EA group while OSI values were higher in that groups compared with EA group. Histological tissue damage was milder in the EA treatment group than in the I/R group. Conclusion: These results suggest that EA treatment protected the rats lung tissue against intestinal I/R injury.

Abstract
PURPOSE OF REVIEW To review the evidence for candidate biomarkers of gastrointestinal toxicity following pelvic radiotherapy to highlight recent findings of potential interest to those involved in the treatment of pelvic malignancies or the management of gastrointestinal consequences of cancer treatments. RECENT FINDINGS Multiple serum and faecal biomarkers have been studied for use in the detection of gastrointestinal toxicity following pelvic radiotherapy. There is no single biomarker that has been shown to be useful and studies have been hampered by the lack of a 'gold standard' test to confirm the presence of toxicity. Given the complex effects of pelvic radiotherapy on the gastrointestinal tract, it is likely that a panel of biomarkers would be necessary in clinical practice. SUMMARY Biomarkers for gastrointestinal toxicity have a potential role in determining the outcomes of current and evolving radiotherapy techniques, identifying those patients at risk of greater degrees of toxicity to facilitate individualized treatment and determining whether symptoms that develop following treatment are related to the previous radiotherapy. Outcome measurement of pelvic radiotherapy has been plagued by inaccurate terminology and crude outcome measures. An accurate and acceptable biomarker or panel of biomarkers has the potential to revolutionize cancer management from treatment planning to posttreatment care. Several candidate biomarkers show promising results, but further robust research is required to clearly identify reliable biomarkers that can be translated into clinical practice.

Abstract
Regimen-related mucosal toxicity is extremely common following cytotoxic chemotherapy and radiotherapy. The alimentary mucosa is particularly susceptible to injury and dysfunction, leading to a constellation of adverse side effects. Currently there is no "one fit" biomarker of such injury. A number of biomarkers have been investigated in the context of gastrointestinal diseases, which may prove useful in the oncology arena. Two of significant potential include citrulline and calprotectin, however more work is required to define the most appropriate settings for their use. Identification of a biomarker that is easily obtained, measured, and accurately indicates mucosal damage, would allow for improved patient diagnosis of toxicities and prompt appropriate intervention. In this review, we highlight the effectiveness of currently examined biomarkers and discuss future avenues for research in this exciting area.

Abstract
BACKGROUND Current evaluation of radiation-induced mucositis in head and neck cancer relies on subjective scoring with interrater variability. We evaluated serum erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) as objective markers of radiation-induced mucositis. METHODS Weekly serum CRP and ESR levels were measured in patients treated for head and neck cancer with radiation ± chemotherapy. Acute radiation toxicity was evaluated using National Cancer Institute of Canada-Common Toxicity Criteria (NCIC-CTC) version 2.0 and the Head and Neck Radiotherapy Questionnaire (HNRQ). RESULTS ESR and CRP levels were significantly elevated by 3 weeks (p = .01) and 6 weeks (p = .0002), respectively, and independent of age or pretreatment surgery. ESR was significantly dependent on radiation dose (p = .0004) and significantly higher with chemoradiation (p = .03). CONCLUSION Serum ESR and CRP rise reliably in a radiation dose-dependent manner. ESR correlated with clinical symptoms and distinguished patients receiving chemoradiation. ESR and CRP may be an objective and sensitive marker of radiation-induced mucositis.

Abstract
Human transferrin has been biolabelled with gold nanoclusters (Au NCs) using a simple, fast and non-toxic method. These nanocrystals (<2 nm) are stabilized in the protein via sulfur groups and have a high fluorescence emission in the near infrared region (QY=4.3%; λem=695 nm). Structural investigation and photophysical measurements show a high population of clusters formed of 22-33 gold atoms covalently bound to the transferrin. In solutions with pH ranging from 5 to 10 and in buffer solutions (PBS, HEPES), those biolabelled proteins exhibit a good stability. No significant quenching effect of the fluorescent transferrin has been detected after iron loading of iron-free transferrin (apoTf) and in the presence of a specific polyclonal antibody. Additionally, antibody-induced agglomeration demonstrates no alteration in the protein activity and the receptor target ability. MTT and Vialight® Plus tests show no cytotoxicity of these labelled proteins in cells (1 µg ml(-1)-1 mg ml(-1)). Cell line experiments (A549) indicate also an uptake of the iron loaded fluorescent proteins inside cells. These remarkable data highlight the potential of a new type of non-toxic fluorescent transferrin for imaging and targeting.

Abstract
Additional large animal models for the acute radiation syndrome (ARS) would facilitate countermeasure development. We demonstrate here that Gottingen minipigs develop hematopoietic ARS symptoms similar to those observed in canines, non-human primates (NHPs) and humans. Dosimetry for whole-body γ irradiation (0.6 Gy/min) was performed using electronic paramagnetic resonance (EPR) with alanine; National Institute of Standards and Technology (NIST)-calibrated alanine pellets and water-filled Plexiglas phantoms were used. After irradiations of 1.6-2.0 Gy, blood pancytopenia was observed for several weeks, accompanied by the characteristic ARS stages: prodromal symptoms, latent period, illness and recovery or morbidity. Morbidity occurred between days 14 and 27, with a preliminary LD(50/30) estimate between 1.7 and 1.9 Gy. The criterion of whether platelet counts were <200 × 10(3)/µl 7 days postirradiation predicted whether animals would survive in 18 out of 20 cases. The degree of granulocytosis 3 h postirradiation was inversely correlated with survival. Animals euthanized based on preset morbidity criteria displayed signs of multi-organ dysfunction, including widespread internal hemorrhage and alterations in organ function reflected in blood chemistry. Circulating C-reactive protein (CRP), a marker for inflammation, became elevated within hours after irradiation, subsided after several days, and increased again after 14 days. The results support further development of the Gottingen minipig as a model for ARS.

Abstract
BACKGROUND The purpose of this study was to test whether nutritional status of patients with head and neck cancer changes during and after treatment. METHODS Nutritional status (including body weight, lean mass, and fat mass) and dietary intake were assessed in 29 patients with head and neck cancer. Patients were assessed 1 week before, and 1 and 4 months after treatment (radiotherapy, either alone or combined with chemotherapy or surgery). RESULTS During treatment, body weight (-3.6 ± 5.3 kg; p = .019) and lean mass (-2.43 ± 2.81 kg; p = .001) significantly declined. Patients with sufficient intake (≥35 kcal and ≥1.5 grams protein/kg body weight) lost less body weight and lean mass than patients with insufficient intake (mean difference, -4.0 ± 1.9 kg; p = 0.048 and -2.1 ± 1.0 kg; p = .054, respectively). After treatment, only patients with sufficient intake gained body weight (2.3 ± 2.3 kg) and lean mass (1.2 ± 1.3 kg). CONCLUSION Patients with head and neck cancer fail to maintain or improve nutritional status during treatment, despite sufficient intake.

Abstract
There are urgent needs to establish capability to rapidly assess radiation injury in mass casualty and population monitoring scenarios. This study's objective was to evaluate several currently available biomarkers that can provide early diagnostic triage information after radiation exposure. Hematology and blood chemistry measurements were performed on samples derived from a nonhuman primate (Macaca mulatta; n = 8) total-body irradiation (TBI) model (6.5-Gy Co gamma rays at 0.6 Gy min). The results from this study demonstrate: a) time course for changes in C-reactive protein (CRP) (-2 d to 15 d after TBI); b) time-dependent (-2 d, 1-4 d after TBI) changes in blood cell counts [i.e., lymphocytes decrease to 5-8% of pre-study levels at 1 to 4 d after TBI; ratio of neutrophil to lymphocytes increases by 44 +/- 18 (p = 0.016), 12 +/- 4 (p = 0.001), 8 +/- 2 (p = 0.0020), and 5.0 +/- 2 (p = 0.002) fold at 1, 2, 3, and 4 days after TBI, respectively]; and c) 4.5 +/- 0.8 (p = 0.002)-fold increases in serum amylase activity 1 d after TBI. Plasma CRP levels at 1 d after exposure were 22 +/- 13 (p = 0.0005) (females) and 44 +/- 11 (p = 0.0004) (males)-fold elevated above baseline levels. One hundred percent successful separation of samples from exposed macaques (24 h after TBI) vs. samples from the same macaque taken before irradiation using a discriminant analysis based on four biomarkers (i.e., lymphocytes, neutrophils, ratio of neutrophils to lymphocytes, and serum amylase activity) was demonstrated. These results demonstrate the practical use of multiple parameter biomarkers to enhance the discrimination of exposed vs. non-exposed individuals and justify a follow-on rhesus macaque dose-response study.

Abstract
INTRODUCTION Both local (Klintrup criteria) and systemic (Glasgow Prognostic Score, mGPS) inflammatory responses have been reported to be independent predictors of cancer-specific survival in colorectal cancer. However, high-grade local inflammatory response appears more common in rectal and high mGPS more common in colonic tumors. Whether relationships with survival are similar in colon and rectal tumors is unclear. The present study assesses the prognostic value of local and systemic inflammation in colon and rectal cancers and defines 3-year survival according to inflammation-based criteria for stage II/III disease. METHODS Two hundred forty colon and 140 rectal cancer patients underwent potentially curative surgery between 1997 and 2007. C-reactive protein and albumin (mGPS) were measured preoperatively. Routine pathology specimens were scored according to Klintrup criteria for peritumoral infiltrate. RESULTS Patients with colon cancers were older (P < 0.05) and had higher T stage (P < 0.001) and mGPS (P < or = 0.001) compared with rectal cancers. The proportions of patients with a high-grade tumor inflammatory cell infiltrate were similar in colon and rectal cancers. mGPS and Klintrup criteria were independent predictors of cancer survival. The mGPS hazard ratios were 1.56 and 1.76 for the mGPS, and the Klintrup hazard ratios were 2.12 and 5.74 for colon and rectum, respectively. For stages II and III colorectal cancer, 3-year survival was 91% and 73%, respectively. Three-year survival varied between 100% and 68% depending on Klintrup score/ mGPS in stage II disease and between 97% and 60% in stage III disease. CONCLUSION Local and systemic inflammatory responses are important independent predictors of survival in colon and rectal cancers. These scores combined with tumor-node-metastases stage improve the prediction of survival in these patients.

Explorative study on the predictive value of systematic inflammatory and metabolic markers on weight loss in head and neck cancer patients undergoing radiotherapy. Support Care Cancer 2009; 18:1385-91.

Abstract
PURPOSE This study aimed to explore the predictive value of systematic inflammatory and metabolic markers in head and neck (H&N) cancer patients during radiotherapy (RT). METHODS Twenty-seven patients were evaluated. The protocol included serial blood tests [highly sensitive C-reactive protein (hsCRP), albumin, insulin-like growth factor 1 (IGF-1), IGF binding protein 1 (IGFBP-1) and ghrelin], measurements of body weight and assessment of oral mucositis. RESULTS The mean nadir of weight loss was observed at the end of RT. At the time of diagnosis, mean hsCRP was 5.2 ± 1.0 mg/L. HsCRP significantly increased during RT and decreased during the post-RT period. Mean maximum hsCRP was 35.8 ± 8.5 mg/L, with seven patients reaching >40 mg/L. A numerical decrease of albumin (by 18.2%) and only small changes in IGF-1, IGFBP-1 and ghrelin levels were observed. None of the metabolic parameters was significantly associated with weight loss. CONCLUSIONS HsCRP increased in response to RT for H&N cancer as a sign of irradiation-induced inflammation. Weight loss was not preceded by changes of the metabolic parameters, indicating that assessment of the blood markers used in this study is of little value. Regular body weight measurement and assessment of oral mucositis are feasible, cheap and important procedures to control the metabolic homeostasis during RT.

Abstract
BACKGROUND A pronounced tumour inflammatory infiltrate is known to confer a good outcome in colorectal cancer. Klintrup and colleagues reported a structured assessment of the inflammatory reaction at the invasive margin scoring low grade or high grade. The aim of the present study was to examine the prognostic value of tumour inflammatory infiltrate in node-negative colorectal cancer. METHODS Two hundred patients had undergone surgery for node-negative colorectal cancer between 1997 and 2004. Specimens were scored with Jass' and Klintrup's criteria for peritumoural infiltrate. Pathological data were taken from the reports at that time. RESULTS Low-grade inflammatory infiltrate assessed using Klintrup's criteria was an independent prognostic factor in node-negative disease. In patients with a low-risk Petersen Index (n=179), low-grade infiltrate carried a threefold increased risk of cancer death. Low-grade infiltrate was related to increasing T stage and an infiltrating margin. CONCLUSION Assessment of inflammatory infiltrate using Klintrup's criteria provides independent prognostic information on node-negative colorectal cancer. A high-grade local inflammatory response may represent effective host immune responses impeding tumour growth.

Abstract
PURPOSE To evaluate the relationship between C-reactive protein (CRP) levels or the erythrocyte sedimentation rate (ESR) and the grade of acute radiation-induced mucositis in patients with head-and-neck cancer. METHODS AND MATERIALS This study was performed in 40 patients who received intensity-modulated radiation therapy as a radical treatment of primary laryngo-pharyngeal cancer. Serum CRP level and ESR were initially checked on the day of radiotherapy simulation and were measured every week during the irradiation schedule and two times biweekly after radiotherapy. Mucosal reactions were evaluated by radiation oncologists on days of blood sampling. RESULTS The distribution of the most severe mucositis was Grade I mucositis in 10% of the patients, Grade II in 60% of the patients and Grade III in 30% of the patients. Statistical analysis indicated a significant rise in the CRP level (p < 0.001) according to radiation fraction number and grade of mucositis. A change of the mean CRP level was correlated with progression of mean grade of mucositis according to fraction number. The ESR did not show any statistically significant relationship with radiotherapy fraction number and grade of acute mucositis. CONCLUSIONS There was a significant correlation between the presence of acute mucositis and CRP level in this study. The CRP level could be conveniently determined along with evaluation of mucosal reactions during or after radiotherapy to provide further information on radiation-induced mucositis.

Abstract
Based on a recent description of an apoptosis stimulating property for hepatocyte derived isoferritins, this investigation demonstrates that ferritin, released in vitro from hepatocytes substantially contributes to density dependent apoptosis in primary hepatocytes and is significantly (P < or = 0.05) inhibited by anti-H-ferritin antibody rH02. Furthermore, total protein release and albumin secretion rapidly decline in a time and density dependent mode under serum-free conditions, whereas ferritin secretion, which is upregulated at initial stages of primary culture is not affected by cell density. Supplementation with dexamethasone (DEX) or proliferative stimulation by epidermal growth factor (EGF) and insulin strongly suppresses density dependent apoptosis. Both regimens have previously been shown to inhibit isoferritin mediated apoptosis in hepatocytes, most likely by interrupting proapotitc mitochondrial signalling. Finally, FasL/Fas also participates in density dependent apoptosis, since apoptosis is significantly (P < or = 0.005) reduced in high density cultures supplemented with an anti-FasL antibody. This antibody has also been shown to neutralise ferritin mediated apoptosis in primary hepatocytes, suggesting a linkage of ferritin and Fas in density dependent apoptosis. In conclusion, ferritin contributes to apoptosis in primary hepatocytes in an autocrine, density dependent mode, involving Fas stimulation and proapoptotic mitochondrial signalling. With respect to liver physiology, these findings may indicate that ferritin plays a yet unrecognised role as an acute phase signalling molecule in early stages of tissue repair and liver regeneration, and may also be responsible for the limited ability to propagate human hepatocytes in culture and the limited expansion of donor cells in the recipient liver upon cell transplantation.

Abstract
BACKGROUND Reliable, non-invasive biological markers of the severity of radiotherapy-induced damage to the gastrointestinal tract are not available. Clinicians continue to use symptom scores as surrogate indicators of toxicity. AIM To determine whether levels of potential biochemical markers of mucosal toxicity change during pelvic radiotherapy. METHODS Fifty-nine patients (30:29 males:females) with mixed pelvic malignancies, receiving 45-70 Gy were recruited. At baseline and weeks 4 or 5 of radiotherapy, blood samples for citrulline, C-reactive protein, eosinophil cationic protein and stool samples for faecal calprotectin were obtained. Symptoms were measured using the Inflammatory Bowel Disease Questionnaire - Bowel Subset, Radiation Therapy Oncology Group and Vaizey Incontinence Questionnaires. Paired t-tests of change in marker values were calculated. RESULTS Citrulline (P = 0.02) and faecal calprotectin (P = 0.01) values changed significantly between baseline and 4/5 weeks. Inflammatory Bowel Disease Questionnaire - Bowel Subset fell significantly (mean fall = 10 points, s.d.: 8.9). Changes in markers did not correlate with symptoms. CONCLUSIONS Some biochemical markers of mucosal toxicity change significantly during treatment. Further studies must investigate the timing of changes of these biochemical markers, their relationship to gastrointestinal physiological change and the radiotherapy dose delivered to the gastrointestinal tract and whether changes in markers acutely can predict the degree of long-term gastrointestinal dysfunction.

Serum levels of c-reactive protein, lactate dehydrogenase, ferritin, haptoglobin, plasma fibrinogen levels and erythyrocyte sedimentation rate were measured. The serum levels of c-reactive protein was found to be increased in 74% of cancer patients, with 81.3% and 64.4% in metastatic and non-metastatic group, respectively. Our study showed that c-reactive protein and fibrinogen demonstrated better characteristics than other acute phase proteins to differentiate between cancer patients and healthy individuals and also to differentiate between healthy individuals and patients with infection. C-reactive protein, ferritin, fibrinogen, erythrocyte sedimentation rate, and haptoglobin showed similar characteristics to differentiate metastatic and non-metastatic cancer patients whereas, LDH demonstrated the lowest performance. C-reactive protein was not found to be superior to other acute phase proteins in the differential diagnosis of cancer and infection and in differentiating early stage disease from advanced stage.

Abstract
An elevated C-reactive protein (CRP) is a valuable marker of disease activity in Crohn's disease and predicts colectomy in ulcerative colitis. It is sometimes elevated in patients with chronic gastrointestinal symptoms following pelvic radiotherapy. Its significance in this context has not been evaluated. The aim of this study was to investigate the significance of elevated CRP in patients with new gastrointestinal symptoms starting after pelvic radiotherapy. Patients at presentation to a specialist clinic had their CRP measured. The diagnoses reached were grouped into categories and correlated with the level of the CRP using logistic regression analysis. Between 2001 and 2004, 159 patients [91 women (median age 61 years), 68 men (median age 69.5 years)] with new gastrointestinal symptoms after pelvic radiotherapy (median 3 years previously) had their CRP checked. In total, 132 (83%) patients had a normal CRP (<10 mg/L). Twenty-seven had an elevated CRP (median 18, range 10-79 mg/L). Eight categories of diagnosis were recorded for patients, including advanced neoplasia (n = 18), small bowel disease (n = 43), large bowel disease (n = 42), ano-rectal disease (n = 72), infection (n = 5), pancreatic insufficiency (n = 5), drugs (n = 7) and normal/other (n = 45). On univariate analysis, presence of advanced neoplasia [P = 0.01 (OR 3.85, 95% CI 1.34-11.1)] and the presence of pancreatic insufficiency [P = 0.026 (OR 8.13, 95% CI 1.29-51.23)] were associated with an elevated CRP. An elevated CRP level is not a prominent feature of uncomplicated chronic radiation-induced toxicity in the gastrointestinal tract. If present in patients with suspected radiation-induced damage, other causes must be sought.

Increase of hepcidin plasma and urine levels is associated with acute proctitis and changes in hemoglobin levels in primary radiotherapy for prostate cancer. J Cancer Res Clin Oncol 2006; 133:297-304. [PMID: 17393200 DOI: 10.1007/s00432-006-0170-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2006] [Revised: 10/11/2006] [Accepted: 11/01/2006] [Indexed: 12/21/2022]
Abstract
PURPOSE To analyse hepcidin serum and urine levels during radiotherapy for prostate cancer. METHODS In 18 patients undergoing radiotherapy for prostate cancer, blood, plasma, and urine samples were taken before and during radiotherapy. Complete blood cell count, pro-hepcidin-, ferritin-, transferrin-, IL-1beta-, IL-6-, and TNF-alpha concentration was determined. Pro-hepcidin concentration was additionally measured in urine samples. Toxicity was evaluated weekly. Differences among tested factors were tested by Wilcoxon rank sign test for paired data. RESULTS In ten patients developing acute radiation-induced proctitis, a significant increase in pro-hepcidin, IL-6, and TNF-alpha plasma levels (p < 0.05) was detected. Pro-hepcidin urine levels also showed a strong trend towards increase (p = 0.06). Concurrently, hemoglobin, and leucocytes were significantly decreased in the patients with acute proctitis (p < 0.05). In eight patients showing no symptoms of proctitis, solely a significant decrease for leucocytes was detected. Additive, these patients showed a significant increase of ferritin, and a decrease of transferrin levels (p < 0.05). CONCLUSIONS Hepcidin levels are increased and hemoglobin is decreased during radiotherapy for prostate cancer in patients who develop acute proctitis. Radiation-induced expression of cytokines may be responsible for increased hepcidin expression in the liver. Regulation of iron metabolism by hepcidin may be an underestimated response in radiotherapy.

Abstract
There is increasing evidence that the presence of a systemic inflammatory response plays an important role in survival following curative resection for colorectal cancer. The present study evaluated the relationship between C-reactive protein concentrations and survival in a cohort of patients receiving adjuvant 5-fluorouracil (5-FU) chemotherapy following potentially curative resection for colorectal cancer. In all, 222 patients undergoing potentially curative resection for colorectal cancer were studied. Of these, 50 patients received adjuvant 5-FU-based chemotherapy. Circulating concentrations of C-reactive protein were measured prior to surgery. The minimum follow-up was 15 months; the median follow-up of the survivors was 38 months. During this period 61 patients died, 32 patients of their cancer and 29 of intercurrent disease. In those patients who did not receive adjuvant chemotherapy, age (P < 0.001), Dukes stage (P < 0.05) and an elevated C-reactive protein (P < 0.01) were significantly associated with survival. In those patients who did receive adjuvant chemotherapy, an elevated C-reactive protein concentration (P < 0.01) was significantly associated with survival. The presence of a systemic inflammatory response is an independent predictor of poor outcome in patients receiving adjuvant 5-FU-based chemotherapy following potentially curative resection for colorectal cancer.

Abstract
There are many proteins that can multi-task. Transferrin, widely known as an iron-binding protein, is one such example of a multi-tasking protein. In this review, the multiple biological actions of transferrin, including its growth and cytoprotective activities, are discussed with the view of highlighting the potential therapeutic applications of this protein.
