Inflammatory Undifferentiated Pleomorphic Sarcoma Mimicking Bacteremia in an Elderly Patient: A Case Report. ACTA ACUST UNITED AC 2021; 57:medicina57020175. [PMID: 33670681 PMCID: PMC7922332 DOI: 10.3390/medicina57020175] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 02/06/2021] [Accepted: 02/09/2021] [Indexed: 11/16/2022]
Abstract
Undifferentiated pleomorphic sarcoma (UPS) is major type of soft tissue sarcomas. UPS presenting with inflammation is rare, and its pathophysiology remains unclear. Herein, we report a rare case of UPS with prolonged fever. A 91-year-old female complaining of high fever was referred to our hospital because of a high C-reactive protein (CRP) level of 12.51 mg/dL. She had been experiencing intermittent fevers for approximately 10 years. The fever of unknown origin worsened with time and went into remission with repeated antimicrobial therapy. She also had a mass on her central lower back over the sacral region for 6 years, which showed a gradual increase in size. The blood tests showed that the leukocyte count and neutrophils were 6.51 × 103 /µL and 70.3%, respectively. She had a 10 × 10 cm mass on her buttock that showed 2-[fluorine-18] fluoro-2-deoxy-d-glucose (FDG) accumulation on FDG-positron emission tomography-computed tomography examination (standardized uptake value-max value: 5.4). A blood culture examination was performed to rule out bacteremia, however, no bacteria were identified. We then performed a needle biopsy and confirmed the diagnosis of UPS; subsequently, the patient underwent a wide-margin resection. A few days after the surgery, her CRP, leukocyte, and neutrophil levels decreased to 0.305 mg/dL, 2.83 × 103/uL, and 50.1%, respectively. This case demonstrated that UPS with inflammation should be treated surgically as soon as possible after ruling out other sources of infection to achieve a favorable prognosis.

The value of C-reactive protein as an independent prognostic indicator for disease-specific survival in patients with soft tissue sarcoma: A meta-analysis. PLoS One 2019; 14:e0219215. [PMID: 31260491 PMCID: PMC6602474 DOI: 10.1371/journal.pone.0219215] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Accepted: 06/18/2019] [Indexed: 12/17/2022] Open
Abstract
Backgrounds Serum C-reactive protein (CRP) level has been shown to be a predictor of survival for multiple cancer types. The aim of this study was to evaluate whether pretreatment serum CRP level could serve as a reliable independent prognostic indicator for survival in patients with soft tissue sarcoma (STS). Methods A detailed literature search was conducted in Medline, Embase and Cochrane for relevant research publications written in English. Patients’ clinical characteristics, outcomes of disease-specific survival (DSS) and disease/recurrence free survival (DFS/RFS) were extracted. Only the results of multivariate survival analysis were recruited in our analysis. Pooled hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) were calculated to evaluate the prognostic role of CRP. This study was registered on PROPERO and the registration number is CRD42018104802. Results Nine articles containing 1655 patients were identified as eligible studies. The random effects model showed that elevated CRP level was significantly correlated with poor DSS (HR = 2.08; 95% CI: 1.33–3.24; p < 0.001). After excluding the heterogeneous study, the fixed effects model showed that elevated CRP level was firmly correlated with poor DSS (HR = 2.36; 95% CI: 1.84–3.03; p < 0.001). The fixed effects model revealed that elevated CRP level was significantly correlated with poor DFS (HR = 1.78; 95% CI: 1.39–2.30; p < 0.001) among studies have more than 100 samples. Conclusion The results of this meta-analysis suggest that elevated pretreatment serum CRP level could serve as an independent risk factor for poor DSS and DFS/RFS in STS patents.

The role of CRP and ATG9B expression in clear cell renal cell carcinoma. Biosci Rep 2017; 37:BSR20171082. [PMID: 28923830 PMCID: PMC5686392 DOI: 10.1042/bsr20171082] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 09/11/2017] [Accepted: 09/13/2017] [Indexed: 12/28/2022] Open
Abstract
The purpose of the study is to investigate the correlation between the expression of C-reactive protein (CRP) and autophagy-related 9B (ATG9B) and pathological features of clear cell renal cell carcinoma (CCRCC) patients. We also intended to explore the effects of manipulated expression of CRP and ATG9B on the apoptosis and cell cycle progression of CCRCC cell line. ATG9B expression in CCRCC tissues and adjacent renal tissues was analyzed by immunohistochemistry (IHC). Gene expression was determined at transcription and translational levels using real-time quantitative PCR (RT-qPCR) and Western blot. The association between CRP/ATG9B expression and clinical-pathological parameters including age, gender, pathological grades, TNM stage and distant metastasis of the patients was assessed by correlation analysis. siRNA and overexpression plasmids construction were used to manipulate the expression of CRP in human CCRCC cell line 786-O. Cell apoptosis and cell cycle progression were determined using flow cytometry (FCM) and Hoechst 33258 staining. CRP expression correlates with ATG9B expression. The expression of CRP and ATG9B are significantly correlated with TNM staging, distant metastasis, and survival time of CCRCC patients. A high-level of CRP indicates a poor overall survival (OS). In addition, CRP expression influences cell cycle and apoptosis of CCRCC cells. The study reveals that CRP might be a CCRCC development promoter. In addition, there is a close relationship between CRP and ATG9B in CCRCC carcinogenesis.

C-reactive protein as a prognostic factor in patients with chordoma of lumbar spine and sacrum--a single center pilot study. World J Surg Oncol 2016; 14:111. [PMID: 27091202 PMCID: PMC4836072 DOI: 10.1186/s12957-016-0875-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2015] [Accepted: 04/13/2016] [Indexed: 12/24/2022] Open
Abstract
Study design This is a retrospective, diagnostic study, level IV. Background It appears to be necessary to identify prognostic markers for individual risk estimation for progression and survival in patients with chordoma, a rare disease. Are pre-operative serum levels of C-reactive protein (CRP) associated with disease progression and survival? Methods Survival rates of 24 patients (18 males, 6 females) (mean age 67 years (SD ± 16; range 20–85 years); minimum follow-up 2 years, mean follow-up 5 years (SD ± 5; range 2–19 years)) with chordoma of the lower spine and sacrum were assessed with a focus on pre-operative CRP levels. Results The survival rate of patients with pre-operative CRP level of >1.0 mg/dl was lower than that of patients with a CRP level <1.0 mg/dl (p = 0.01). The estimated 10-year survival of patients with pre-operative CRP values <1.0 and >1.0 mg/dl was 76 and 25 %, respectively. CRP remained as an independent survival factor (p = 0.025; CI 95 % 1.0–2.6) in multivariable analysis. Conclusions Pre-operative CRP levels appear to be a biomarker for disease-specific survival in patients with chordoma of the lumbar spine and sacrum. A validation of our finding with larger cohorts and integration of putative risk factor would further elucidate CRP a surrogate for tumor progression.

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: 171] [Impact Index Per Article: 19.0] [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.

Paraneoplastic Syndrome of Angiomatoid Fibrous Histiocytoma May Be Caused by EWSR1-CREB1 Fusion-induced Excessive Interleukin-6 Production. J Pediatr Hematol Oncol 2015; 37:554-9.

Abstract
We describe a 7-year-old girl with angiomatoid fibrous histiocytoma (AFH) presenting severe inflammatory symptoms. The cytokine/chemokine profile of serum samples before and after surgery demonstrated that interleukin (IL)-6 had decreased by the greatest percentage. The AFH cells were immunopathologically positive for IL-6 and Tyr705-phosphorylation of signal transducer and activator of transcription 3. The EWSR1-CREB1 fusion gene detected in the tumor leads to continuous activation of CREB1 and IL-6 production, because the promoter region of IL-6 has a CREB binding site. Thus, IL-6 plays pivotal roles in both paraneoplastic syndrome and the oncogenesis of AFH.

Abstract
The aim of this study is to assess whether preoperative serum interleukin-6 (IL-6) can predict recurrence of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). The association between preoperative IL-6 levels and HCC recurrence following curative hepatectomy in 146 patients with chronic HBV infection was determined. Patients were divided into groups based on the presence or absence of HCC recurrence. Serum IL-6 levels were compared between groups, and the association between serum IL-6 level and greatest tumor dimension was also analyzed. Receiver operating characteristics (ROC) curve was used to define the optimal cutoff value for predicting recurrence-free survival (RFS) and overall survival (OS) rates. The OS and RFS rates were calculated using the Kaplan-Meier method. Out of 146 patients, 80 (54.8%) patients were documented as having HCC recurrence during the follow-up period. After adjusting for potential confounders, serum IL-6 levels were significantly associated with HCC recurrence, and a saturation effect existed with serum IL-6 levels up to 3.7 pg/mL. In addition, patients with preoperative serum IL-6 levels over 3.1 pg/mL had lower RFS and OS rates (P < 0.01). There was no significant correlation between preoperative serum IL-6 levels and maximal tumor dimension (r = 0.0003, P = 0.84). Elevated serum levels of IL-6 were significantly associated with an increased risk of HBV-associated HCC recurrence suggesting that preoperative IL-6 serum level is potential biomarker for early prediction of HBV-associated HCC recurrence.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) is a useful predictive factor in several cancers. However, the prognostic value of NLR in patients with esophageal cancer (EC) is still controversial. Therefore, it was necessary for us to perform a meta-analysis to evaluate the prognostic value of NLR in patients with EC. METHODS A systematic literature search was performed by using Web of Science, PubMed Central, and Medline to evaluate the prognostic value of NLR in patients with EC. The deadline of our primary search was July 10, 2014. This meta-analysis was conducted in accordance with PRISMA guidelines. Pooled hazard ratio (HR) with 95% confidence interval (CI) was used to assess the association of NLR and overall survival (OS) and disease-free survival (DFS). RESULTS Six studies involving 1,633 patients were included in our meta-analysis. Our pooled results demonstrated that high NLR was associated with poor OS (HR: 1.54, 95% CI: 1.32-1.80, I2=25.3%, P=0.254) and DFS (HR: 1.74, 95% CI: 1.25-2.43, I2=63.9%, P=0.096). Subgroup analysis between NLR and OS was performed in a further investigation. When the patients were segregated according to country, sample size, and pathological type, high NLR was also significantly correlated with OS. CONCLUSION High NLR is associated with poor prognosis in patients with EC. NLR may be a significant predictive biomarker in patients with EC.

Abstract
Cardiac tumors are assumed to be a rare entity. Metastases to the heart are more frequent than primary lesions. Sarcomas make up the majority of cardiac malignant neoplasms. Among them angiosarcoma is the most common and associated with the worst prognosis. Malignant fibrous histiocytoma comprises the minority of cardiac sarcomas and has uncertain etiology as well as pathogenesis. Transthoracic echocardiography remains the widely available screening examination for the initial diagnosis of a cardiac tumor. The clinical presentation is non-specific and the diagnosis is established usually at an advanced stage of the disease. Sarcomas spread preferentially through blood due to their immature vessels without endothelial lining. Surgery remains the method of choice for treatment. Radicalness of the excision is still the most valuable prognostic factor. Adjuvant therapy is unlikely to be effective. The management of cardiac sarcomas must be individualized due to their rarity and significant differences in the course of disease.

Validation of the prognostic relevance of plasma C-reactive protein levels in soft-tissue sarcoma patients. Br J Cancer 2013; 109:2316-22.

Abstract
BACKGROUND The concept of the involvement of systemic inflammation in cancer progression and metastases has gained attraction within the past decade. C-reactive protein (CRP), a non-specific blood-based marker of the systemic inflammatory response, has been associated with decreased survival in several cancer types. The aim of the present study was to validate the prognostic value of pre-operative plasma CRP levels on clinical outcome in a large cohort of soft-tissue sarcoma (STS) patients. METHODS Three hundred and four STS patients, operated between 1998 and 2010, were retrospectively evaluated. CRP levels and the impact on cancer-specific survival (CSS), disease-free survival (DFS) and overall survival (OS) were assessed using Kaplan-Meier curves and univariate as well as multivariate Cox proportional models. Additionally, we developed a nomogram by supplementing the plasma CRP level to the well-established Kattan nomogram and evaluated the improvement of predictive accuracy of this novel nomogram by applying calibration and Harrell's concordance index (c-index). RESULTS An elevated plasma CRP level was significantly associated with established prognostic factors, including age, tumour grade, size and depth (P<0.05). In multivariate analysis, increased CRP levels were significantly associated with a poor outcome for CSS (HR=2.05; 95% CI=1.13-3.74; P=0.019) and DFS (HR=1.88; 95% CI=1.07-3.34; P=0.029). The estimated c-index was 0.74 using the original Kattan nomogram and 0.77 when the plasma CRP level was added. CONCLUSION An elevated pre-operative CRP level represents an independent prognostic factor that predicts poor prognosis and improves the predictive ability of the Kattan nomogram in STS patients. Our data suggest to further prospectively validate its potential utility for individual risk stratification and clinical management of STS patients.

Abstract
BACKGROUND The aim of this study was to determine whether the combined use of the C-reactive protein (CRP) level and neutrophil-lymphocyte ratio (NLR) before treatment predicts disease-specific survival in adult patients with soft tissue sarcoma (STS). METHODS We retrospectively reviewed 142 patients who presented with STS between 1995 and 2010. RESULTS The NLR varied from 0.54 to 7.59. An elevated CRP level was observed in 36 patients before treatment. The patients with both an elevated CRP level and high NLR had a poorer disease-specific survival (46% at 5 years) than the patients with both a normal CRP level and low NLR (87% at 5 years) (P = 0.0005). The patients with both an elevated CRP level and high NLR also had a poorer disease-specific survival than the patients with either an elevated CRP level or high NLR (75.6% at five years) (P = 0.03). There were no significantly prognostic differences between the patients with a normal CRP level and low NLR and those with either an elevated CRP level or high NLR (P = 0.18). A multivariate analysis also showed the preoperative NLR and CRP level to be independent predictors of survival. CONCLUSIONS We recommend the routine measurement of these markers to identify patients with a greater risk of death.

Abstract
Background C-reactive protein (CRP) is inversely related to prognosis in many cancers, however, no studies regarding the predictive value of CRP in small cell carcinoma of the esophagus (SCCE) are available. The aim of this study was to determine the prognostic value of preoperative CRP in patients with SCCE. Methods From January 2001 to December 2010, a retrospective analysis of 43 consecutive patients with SCCE was conducted. Univariate and multivariate analyses were performed to evaluate the prognostic parameters. Results In our study, elevated CRP levels (>10 mg/L) were found in 16 patients (37.2%). CRP levels were significantly higher in patients with deeply invasive tumors (P = 0.018) and those associated with nodal metastasis (P = 0.018). Patients with CRP ≤10 mg/L had a significantly better overall survival than patients with CRP >10 mg/L (25.9% vs 6.3%, P = 0.004). Multivariate analyses showed that CRP was a significant predictor for overall survival. CRP >10 mg/L had a hazard ratio of 2.756 (95% confidence interval: 1.115–6.813, P = 0.028) for overall survival. Conclusion Preoperative CRP is an independent predictive factor for long-term survival in patients with SCCE.

Abstract
The aim of this study was to determine whether the level of circulating C-reactive protein (CRP) before treatment predicted overall disease-specific survival and local tumour control in patients with a sarcoma of bone. We retrospectively reviewed 318 patients who presented with a primary sarcoma of bone between 2003 and 2010. Those who presented with metastases and/or local recurrence were excluded. Elevated CRP levels were seen in 84 patients before treatment; these patients had a poorer disease-specific survival (57% at five years) than patients with a normal CRP (79% at five years) (p < 0.0001). They were also less likely to be free of recurrence (71% at five years) than patients with a normal CRP (79% at five years) (p = 0.04). Multivariate analysis showed the pre-operative CRP level to be an independent predictor of survival and local control. Patients with a Ewing's sarcoma or chondrosarcoma who had an elevated CRP before their treatment started had a significantly poorer disease-specific survival than patients with a normal CRP (p = 0.02 and p < 0.0001, respectively). Patients with a conventional osteosarcoma and a raised CRP were at an increased risk of poorer local control. We recommend that CRP levels are measured routinely in patients with a suspected sarcoma of bone as a further prognostic indicator of survival.

Abstract
Background To analyse the prognostic significance of preoperative C-reactive protein (CRP) serum level in patients with upper urinary tract urothelial carcinoma (UUT-UC). Methods We evaluated 158 UUT-UC patients who had undergone surgery in the University Hospital of Hannover (MHH). 143 (89.4%) suffered from cancer in the renal pelvis, 13 (8.1%) patients presented with tumour located in the ureter. A preoperative CRP value was available for 115 patients. The mean (median) follow-up for these patients was 28.3 (15.1) months. Results The median (mean) CRP value of all evaluable patients was 10.0 (40.7) mg/l. The CRP-level, stratified into two subgroups (CRP ≤5 vs. >5 mg/l), correlated significantly with muscle invasive tumour stage (36.4 vs. 78.9%; p<0.001), the risk of presenting nodal disease (4.5 vs. 26.8%; p=0.002) and distant metastasis (2.3 vs. 16.9%; p<0.016). The Kaplan-Meier 5-year cancer specific survival (CSS) rates were 54.2 and 26.4% for patients with preoperative CRP levels ≤ and >5 mg/l, respectively (p<0.006). Next to age and the presence of metastasis, multivariate analysis also identified CRP as a continuous variable as an independent prognosticator for CSS. Conclusions A high preoperative serum CRP level is associated with locally advanced and metastatic disease in patients with UUT-UC. Its routine use could allow better risk stratification and risk-adjusted follow-up of UUT-UC patients.

Abstract
Liver transplantation (LT) is a curative modality for hepatocellular carcinoma (HCC), especially in patients with cirrhosis. However, there are still risks of recurrence. C-reactive protein (CRP), an acute-phase inflammatory reactant that is synthesized by hepatocytes, has been related to the prognosis of various malignancies, including HCC. In this study, we investigated the role of a high CRP level in predicting the posttransplant outcomes of HCC patients. We analyzed 85 patients undergoing LT between August 2000 and July 2010 whose pretransplant serum CRP levels were available. Only 2 patients underwent deceased donor LT, and the remaining patients underwent living donor LT. With 1 mg/dL used as a cutoff value, 27 patients showed high CRP levels (≥1 mg/dL) at the time of LT, and 58 showed low CRP levels (<1 mg/dL). The total bilirubin level, Child-Pugh grade, Model for End-Stage Liver Disease score, maximal tumor size, and frequency of intrahepatic metastasis were significantly higher in the high-CRP group. According to multivariate analyses, HCC beyond the Milan criteria, a high CRP level, and microvascular invasion were related to tumor recurrence, and a high CRP level and microvascular invasion were related to poor overall survival. When a subgroup analysis was performed according to the Milan criteria, a high CRP level was an independent factor for predicting poor outcomes in patients with HCC beyond the Milan criteria (P = 0.02 for recurrence and P < 0.001 for survival) but not in patients with HCC within the criteria. Serum CRP could be considered a useful and cost-effective biomarker for predicting outcomes after LT for HCC, particularly in patients beyond the Milan criteria.

The value of C-reactive protein and comorbidity in predicting survival of patients with high grade soft tissue sarcoma. Eur J Cancer 2012; 49:377-85. [PMID: 23058786 DOI: 10.1016/j.ejca.2012.09.004] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2012] [Revised: 08/26/2012] [Accepted: 09/02/2012] [Indexed: 11/26/2022]
Abstract
BACKGROUND The aim of this study was to determine whether C-reactive protein (CRP) levels or patient's comorbidity before treatment predicted the overall disease-specific survival and local tumour control in high grade soft tissue sarcoma patients. METHODS A total of 332 primary adult soft tissue sarcoma patients were retrospectively reviewed. CRP levels were obtained prior to treatment for all patients. The Charlson comorbidity index (CCI) was used for evaluation as a measure of comorbidity. Patients that presented with metastases at diagnosis were excluded from this study. RESULTS Elevated CRP levels were seen in 152 patients. CCI score varied from 0 to 4. Two-hundred and sixty-five patients had a score of 0 (no identified comorbidity), and 67 patients had a score of 1 or more. Patients with elevated CRP levels prior to initial treatment had a poorer disease-specific survival (42% at 5 years) than patients with normal CRP levels (82% at 5 years) (p<0.0001). Patients with elevated CRP levels had a poorer local recurrence-free rate after initial treatment (75% at 5 years) than patients with normal CRP levels (89% at 5 years) (p=0.0004). Multivariate analysis also showed the preoperative CRP level to be an independent predictor of survival and local control. Although age in patients with identified comorbidity was significantly higher than those in patients with no-identified comorbidity, CCI was not a predictive factor for either survival or local control. CONCLUSION Pretreatment elevated CRP levels were found to be a poor prognostic factor for disease-specific survival and local control for soft tissue sarcoma patients.

Abstract
C-reactive protein (CRP) is an acute-phase reactant that is a promising biomarker in patients with cancer of many kinds. The aim of this retrospective study was to evaluate significant changes in CRP levels as a parameter for the response effect and long-term survival of patients with diffuse large B cell lymphoma (DLBCL). Serum CRP data were collected in 94 patients with DLBCL from October 2006 to August 2009 in Cancer Center, Sun Yat-Sen University. Results were correlated with clinical data. The median CRP serum level in patients with DLBCL was 30.91 ± 53.35 in male and 22.39 ± 29.89 mg/L in female. Base line CRP levels were correlated with International Prognostic Index (IPI) scores (p = 0.03). Among the patients with an IPI score of 1-2, base line CRP levels were correlated with long-term survival (p = 0.001). Base line CRP levels were also correlated with OS (p = 0.001) and varied with different clinical stages (p = 0.03). The corresponding CRP levels in the patients with 2 cycles of chemotherapy were correlated with short-term treatment response (p = 0.003) and OS (p = 0.04) or TTP (p = 0.03). CRP serum levels can be used as additional prognostic parameter in patients with diffuse large B cell type lymphoma.

Abstract
Background Thrombotic microangiopathies (TMA) in adults such as thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are life-threatening disorders if untreated. Clinical presentation is highly variable and prognostic factors for clinical course and outcome are not well established. Methods We performed a retrospective observational study of 62 patients with TMA, 22 males and 40 females aged 16 to 76 years, treated with plasma exchange at one center to identify clinical risk factors for the development of renal insufficiency. Results On admission, 39 of 62 patients (63%) had acute renal failure (ARF) with 32 patients (52%) requiring dialysis treatment. High systolic arterial pressure (SAP, p = 0.009) or mean arterial pressure (MAP, p = 0.027) on admission was associated with acute renal failure. Patients with SAP>140 mmHg on admission had a sevenfold increased risk of severe kidney disease (OR 7.464, CI 2.097–26.565). MAP>100 mmHg indicated a fourfold increased risk for acute renal failure (OR 4.261, CI 1.400–12.972). High SAP, diastolic arterial pressure (DAP), and MAP on admission were also independent risk factors for persistent renal insufficiency with the strongest correlation for high MAP. Moreover, a high C-reactive protein (CRP) level on admission correlated with renal failure in the course of the disease (p = 0.003). At discharge, renal function in 11 of 39 patients (28%) had fully recovered, 14 patients (23%) remained on dialysis, and 14 patients (23%) had non-dialysis-dependent chronic kidney disease. Seven patients (11%) died. We identified an older age as risk factor for death. Conclusions High blood pressure as well as high CRP serum levels on admission are associated with renal insufficiency in TMA. High blood pressure on admission is also a strong predictor of sustained renal insufficiency. Thus, adult TMA patients with high blood pressure may require special attention to prevent persistent renal failure.

Abstract
The heart is the rarest site for neoplasms to be localized. Despite modern diagnostic techniques, cardiac tumours continue to among those discovered latest and with the worst prognoses. We present the case of a 62-year-old woman with a heart tumour and mediastinal lymphadenopathy, who was admitted to the Department of Cardiac Surgery. The patient underwent surgical removal of the tumour with extracorporeal circulation. The left atrium, mitral valve and the left ventricle were occupied by the infiltration. A radical resection appeared to be impossible. A valvular prosthesis was not implanted. The perioperative period was uncomplicated. On the 9(th) day a local recurrence was confirmed in the transthoracic echocardiography. Further oncological diagnostics revealed the spread of the malignant neoplasm to bones of the pelvis and spine. Chemotherapy was initiated. The authors discuss the most appropriate diagnostic and treatment procedures employed in the above case.

Abstract
The rarest subtype of malignant fibrous histiocytoma (MFH) is the inflammatory type, which due to its peculiar clinical presentation may mimic an infectious process such as an abscess. The rarity of this disease and the unique features of its presentation may mislead the surgeon with consequent catastrophic results for the patient. In this study, a case report of a 65-year-old female patient with a soft-tissue inflammatory MFH presenting as a lumbar abscess and a review of the current literature are presented.

Abstract
BACKGROUND The aim of this study was to determine whether circulating C-reactive protein (CRP) levels before treatment predict the overall survival and disease-free survival in soft tissue sarcoma patients. METHODS A total of 102 primary soft tissue sarcoma patients from 2003 to 2009 were retrospectively reviewed. The CRP levels were obtained before treatment for all patients. The patients who presented with metastases at diagnosis were excluded from this study. RESULTS Elevated CRP levels were seen in 18 patients. The tumor histological grade and American Joint Committee on Cancer stage in the patients with elevated CRP levels were significantly higher than those in patients with normal CRP levels. Patients with elevated CRP levels before initial treatment had a poorer overall survival than patients with normal CRP levels (P = .01). The overall survival estimates at 3 and 5 years were 75.3% and 53.8%, respectively, versus 90.3% and 81.3%, respectively. Patients with elevated CRP levels before initial treatment had poorer event-free survival after initial treatment than patients with normal CRP levels (P < .001). The event-free survival estimates at 2 and 5 years were 53.2% and 33.2%, respectively, versus 83.2% and 81.3%, respectively. A multivariate analysis also showed the preoperative CRP level to be an independent predictor of events. CONCLUSIONS The pretreatment serum CRP level may be a marker of aggressive tumor characteristics. Pretreatment elevated CRP levels were found to be a poor prognostic factor for overall survival in a univariate analysis, and for disease-free survival in a multivariate analysis, for soft tissue sarcoma patients.

Abstract
BACKGROUND Disorders in the blood coagulation system are often associated with malignancy. Patients with colorectal cancer (CRC) have been shown to have abnormal data for various coagulation tests. METHODS We retrospectively analyzed the relation between the preoperative plasma fibrinogen level and tumor recurrence in 569 patients with CRC who underwent curative surgical resection and were followed up without adjuvant chemotherapy. RESULTS The plasma fibrinogen level showed a positive association with tumor recurrence, age, sex, T stage, and TNM classification. When divided with the median value, hyperfibrinogenemia is positively correlated with tumor recurrence, although it lost independence in the multivariate analysis. In the C-reactive protein (CRP)-negative population, hyperfibrinogenemia is independently correlated with tumor recurrence and recurrence-free survival. In contrast, hyperfibrinogenemia has no effect on recurrence in CRP-positive patients. CONCLUSIONS Hyperfibrinogenemia is clinically relevant in tumor recurrence before a systemic inflammatory response and thus can be a useful predictor of recurrence in the preinflammatory stage of CRC.

Abstract
This review aims to summarise the physiology of C-reactive protein (CRP), its possible roles and limitations as an inflammatory and infective marker in intensive care medicine, and also the emerging roles of CRP in the pathogenesis of cardiovascular and autoimmune diseases. Observational and animal studies on uses of CRP were retrieved from the PubMed database without any language restrictions. Quantitative data were not pooled because of the heterogeneity of patient characteristics and disparate ways in which CRP was studied. Serum CRP concentrations are determined by the synthetic rate of its production in the liver regulated predominantly by interleukin-6. It has a half-life of 19 hours and is relatively slow in its onset and offset in response to an acute inflammatory process when compared to procalcitonin. It has some favourable properties and limitations as an inflammatory marker. An elevated CRP concentration is not specific to infections and the absolute CRP concentrations cannot be used to differentiate between bacterial, fungal and severe viral infections. The dynamic response of CRP to therapy that aims to modify the underlying inflammatory process and the clinical context of a patient are of pivotal importance when CRP concentrations are interpreted. CRP is found to be a significant partaker and prognostic factor in a wide range of cardiovascular and chronic diseases. In summary, CRP concentration is an important prognostic factor of many acute and chronic diseases. Serial CRP measurements may be useful to reflect a patient's response to therapy that aims to modify the underlying inflammatory process.

Abstract
BACKGROUND/AIMS C-reactive protein (CRP) was recently identified as a prognostic factor for patients with hepatocellular carcinoma (HCC) after surgical resection. We investigated the relationship between the serum levels of high sensitivity CRP (H-CRP) and the prognosis of HCC patients. METHOD We conducted a cohort study of 90 HCC patients enrolled from 1997 to 1998. All patients were treated and followed for a mean period of 3.2 years. Clinical variables were compared between patients positive for H-CRP (serum H-CRP levels >/=3.0 mg/L, n=47) and those negative for H-CRP (serum H-CRP levels <3.0 mg/L, n=43). We also determined the relationship between serum H-CRP and prognosis in HCC patients. RESULTS The survival rate of patients of the H-CRP-positive group was lower than that of H-CRP-negative patients. Tumour stage (stages 3 or 4), total bilirubin >/=1.2 mg/dL, albumin (Alb) <3.5 g/dL, des-gamma-carboxy prothrombin >/=40 mAU/mL, positive H-CRP and initial treatment (transcatheter arterial chemoembolization, hepatic arterial infusion chemotherapy or best supportive care) were identified as significant poor prognostic factors by univariate analysis, while positive H-CRP [hazard ratio (HR), 1.58; P=0.048], Alb<3.5 g/dL (HR, 2.10; P=0.004), tumour stage (stages 3 or 4; HR, 3.05; P=0.001) and initial treatment (HR, 1.88; P=0.029) were considered to be significant determinants of poor prognosis by multivariate Cox proportional hazards analysis. CONCLUSIONS The prognosis of H-CRP-positive patients was poorer compared with H-CRP-negative patients. This study confirmed that H-CRP, like CRP, is a marker of poor prognosis in HCC patients.

Abstract
OBJECTIVE The purpose of this study was to identify prognostic factors in patients with gemcitabine-refractory pancreatic cancer and to determine criteria for selecting candidates for second-line treatment. METHODS The records of 74 patients who were treated with gemcitabine (GEM) and followed up until disease progression were reviewed retrospectively. Sixteen clinical variables at the time of disease progression after GEM chemotherapy were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. RESULTS At the time of analysis, 71 patients had died because of tumor progression. The overall median survival time was 5.1 months after first-line chemotherapy with GEM was initiated. Median survival time after disease progression was 2.0 months. Three factors, performance status, peritoneal dissemination and C-reactive protein level, were identified as independent prognostic factors in multivariate analysis. Median survival time in the good prognosis group (patients with performance status 0 or 1, no peritoneal dissemination and C-reactive protein <5.0 mg/dl) was 3.4 months. CONCLUSIONS Performance status, serum level of C-reactive protein and peritoneal dissemination were identified as important prognostic factors in patients with GEM-refractory pancreatic cancer. These factors should be considered in determining the treatment following first-line chemotherapy in patients with advanced pancreatic cancer.

Abstract
We investigated whether preoperative levels of serum C-reactive protein (CRP) and its correlation with tumour clinicopathological findings adds prognostic information beyond the time of diagnosis in patients with myeloma bone disease (MM) to facilitate the surgical decision-making process. Six hundred and fifty-eight myeloma patients were evaluated retrospectively for surgery. Clinicopathological variables of patients who underwent surgery (n=71) were compared between patients with preoperative CRP ⩾6 mg l−1 and those with CRP <6 mg l−1. Univariate and multivariate analyses were performed to identify prognostic factors after surgery. Patients with an increase of CRP prior to surgery showed inferior survival compared to patients with normal levels. Patients with normal CRP levels at diagnosis but elevations prior to surgery do seem to have a similar unfavourable overall survival (OS) than patients with an increase both, at diagnosis and at surgery. Conversely, patients with normal CRP levels prior to surgery still have the best OS, irrespective of their basic values. Multivariate analysis revealed preoperative CRP levels above 6 mg l−1 Lactate dehydrogenase (LDH) above normal, and osteolyses in long weight bearing bones as independent predictors of survival. These findings suggest that in patients with MM serum levels of CRP increase during disease activity and might be significantly correlated with specific disease characteristics including adverse prognostic features such as osteolyses in long weight bearing bones. Thus, preoperative elevated CRP serum levels might be considered as independent predictor of prognosis and could provide additional prognostic information for the risk stratification before surgical treatment in patients with myeloma bone disease.

Abstract
Despite improved results gained by the combination of neoadjuvant chemotherapy and radiotherapy with surgery, the prognosis for the esophageal carcinoma patient remains poor. There is a need for prognostic markers that can help improve patient selection. The aim of this study was to evaluate whether serum levels of C-reactive protein (CRP) have any influence on the patient prognosis in terms of prediction of chemoradiosensibility, and overall and disease-free survival. Blood samples were obtained at the time of diagnosis in 67 patients with biopsy-proven primary carcinoma of the esophagus. Although not significantly, the mean CRP level was higher than that of 20 patients with benign esophageal pathology who served as controls. No significant correlation could be found between CRP levels and baseline characteristics such as age, gender, histology, cancer localization, tumor depth, lymph node status or metastatic spread. However, patients with CRP levels higher than 6 mg/L were more frequently non-responders to chemoradiotherapy (P = 0.035), had a shorter overall survival (P = 0.061) and a shorter disease-free survival (P = 0.016). It is concluded from these results that pretreatment measurement of serum CRP levels in patients with esophageal cancer could to be used in routine practice as indicators of chemoradiosensibility and prognosis.

Abstract
BACKGROUND The authors evaluated the significance of the preoperative serum C-reactive protein (CRP) level as a prognostic indicator in patients with hepatocellular carcinoma (HCC). METHODS One hundred forty-one patients who underwent curative resection for HCC were reviewed retrospectively. Clinicopathologic variables were compared between patients with serum CRP levels >/= 1.0 mg/dL (n = 22 patients; the CRP-positive group) and patients with serum CRP levels < 1.0 mg/dL (n = 119 patients; the CRP-negative group). Univariate and multivariate analyses were conducted to identify factors that affected survival and disease recurrence. RESULTS There was a significant correlation between the preoperative serum CRP level and tumor size. Invasion to the portal vein in the CRP-positive group was significantly more frequent than that in the CRP-negative group. Even after they underwent curative resection, 75.3% of patients in the CRP-positive group experienced recurrence within 1 year. The overall survival and recurrence-free survival rates in the CRP-positive group were significantly lower compared with the rates in the CRP-negative group. On multivariate analysis, the preoperative serum CRP level was selected as one of the unfavorable indicators regarding survival and recurrence. When CRP levels, albumin levels, and platelet counts that were available before surgery were scored as a combined index, the total score demonstrated a good stratification value for survival after hepatic resection. CONCLUSIONS The current results showed that the preoperative serum CRP level is an independent and significant indicator predictive of poor prognosis and early recurrence in patients with HCC. The new CRP-based scoring system offers reliable information for predicting survival.

Abstract
Pleomorphic malignant fibrous histiocytoma (MFH) is occasionally associated with inflammatory paraneoplastic syndrome (PNS). Recently, we reported that interleukin (IL)-6, one of the candidate cytokines, which induces such systemic inflammatory reaction, may be a tumor-associated factor involved in the pathogenesis and its clinical manifestations of MFH. In the local microenvironment, tumor-induced inflammatory reaction may play a role favoring tumor progression. To clarify the biological relevance of IL-6 in MFH, we established a human MFH cell line, named MIPS-2, derived from a resected specimen of a patient presenting with PNS. In this patient, the serum IL-6 level ran parallel to the disease course: elevated serum IL-6 concentration normalized immediately after radical surgery, and re-elevation occurred on tumor recurrence. MIPS-2 presented pleomorphic appearance, severe nuclear abnormalities with prominent nucleoli, and tumorigenesis in nude mice. MIPS-2 expressed IL-6, IL-6 receptor (IL-6R), and glycoprotein 130 (gp130) but lacked the soluble form of IL-6R (sIL-6R), as determined by flow cytometry and reverse transcriptase-polymerase chain reaction analyses. Stimulation of MIPS-2 with IL-6 combined with exogenous sIL-6R induced phosphorylation of both signal transducer and activator of transcription 3 (STAT3) and mitogen-activated protein kinase (MAPK), decreased cell proliferation, attenuated invasion, and induced morphological changes. Collectively, these data suggested that the IL-6/sIL-6R signaling pathway plays a pivotal role for proliferation, invasion, and morphology of MFH via STAT3 and MAPK pathway as autocrine and/or paracrine manner, and proposed the therapeutic potential for the use of both anti-growth factor and proinflammatory cytokine-targeting strategies to combat devastating MFH.

Abstract
Obesity has recently been linked to mortality from the majority of cancers. The insulin/insulin-like growth factor (IGF) system may partly explain this effect. The metabolic syndrome, associated with hyperinsulinemia, may modulate this effect. Recent evidence supports the role of insulin and IGF-1 as important growth factors, acting through the tyrosine kinase growth factor cascade in enhancing tumor cell proliferation. In addition, the metabolic syndrome associated with a chronic inflammatory state and accompanying cytokine abnormalities may also contribute to tumor progression. Growing links between insulin and the etiology as well as prognosis in colon, prostate, pancreatic, and, particularly, breast cancer are reviewed. Of particular concern is the evidence that elevated IGF-1 may interfere with cancer therapy, adversely affecting prognosis. The role of insulin is of concern because of the increasing levels of obesity and the associated metabolic syndrome. Weight gain, through typical Western diet; limited levels of activity; and, more recently, stress-related changes in neuroendocrine function may lead to insulin resistance and hyperinsulinemia. The opportunity for a multidisciplinary approach involving nutrition, exercise, and stress reduction in an integrative setting may be crucial to limiting the insulin-resistant state and improving cancer outcomes.

Abstract
BACKGROUND AND OBJECTIVES An increased serum C-reactive protein (CRP) level was found in patients with various malignant tumors and was associated with poor prognosis. The aim of this study was to analyze the clinicopathological significance and the prognostic value of preoperative CRP levels in patients with esophageal squamous cell carcinomas. PATIENTS AND METHODS The preoperative CRP level was measured by enzyme-linked immunosorbent assay (ELISA) in 150 patients with primary esophageal squamous cell carcinomas. All patients underwent radical surgery without any preoperative therapy. The patients were divided into two groups using a cut-off value of 1.0 mg/dl. The pathological classifications of the tumor were examined according to the TNM/UICC classification. The associations between the clinicopathological factors and CRP level were determined. The prognostic value of CRP was determined using Cox's proportional hazards model. RESULTS Thirty-five patients (23%) showed high CRP levels (more than 1.0 mg/dl). Statistically significant differences in CRP levels were observed depending on tumor depth (P = 0.022) and TNM/UICC stage (P = 0.001). A high CRP level was associated with poor survival (P = 0.005) and was confirmed by multivariate analysis. CONCLUSIONS A high CRP level is associated with tumor progression and poor survival in patients with esophageal squamous cell carcinoma.
