On detection of periodicity in C-reactive protein (CRP) levels. Sci Rep 2018; 8:11979.

Abstract
C-reactive protein (CRP) is an acute-phase plasma protein that can be used as a biomarker for activation of the immune system. A spectral analysis of CRP level over time for patients with gynaecological tumours has been reported by Madondo et al., using a periodogram method, suggesting that there is no significant periodicity in the data. In our study, we investigate the impact of low sample number on periodogram analysis, for non-uniform sampling intervals—we conclude that data of Madondo et al. cannot rule out periodic behaviour. The search for patterns (periodic or otherwise) in the CRP time-series is of interest for providing a cue for the optimal times at which cancer therapies are best administered. In this paper we show (i) there is no evidence to rule out periodicity in CRP levels, and (ii) we provide a prescription for the minimum data sample rate required in future experiments for improved testing of a periodic CRP signal hypothesis. The analysis we provide may be used for establishing periodicity in any short time-series signal that is observed without a priori information.

Abstract
According to the current World Health Organization (WHO), renal cell carcinomas (RCCs) that primarily affect adults are classified into 8 major subtypes. Additional emerging entities in renal neoplasia have also been recently recognized and these are discussed in further detail by Mehra et al (Emerging Entities in Renal Neoplasia, Surgical Pathology Clinics, 2015, Volume 8, Issue 4). In most cases, the diagnosis of a RCC subtype can be based on morphologic criteria, but in some circumstances the use of ancillary studies can aid in the diagnosis. This review discusses the morphologic, genetic, and molecular findings in RCCs previously recognized by the WHO, and provides clues to distinction from each other and some of the newer subtypes of RCC. As prognosis and therapeutic options vary for the different subtypes of RCC, accurate pathologic distinction is critical for patient care.

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.

Tumor necrosis is a strong predictor for recurrence in patients with pathological T1a renal cell carcinoma. Oncol Lett 2015; 9:125-130.

Abstract
Patients with pT1aN0M0 renal cell carcinoma (RCC) generally have good prognosis, and recurrence is rare. However, metastasis develops postoperatively in a small number of patients with pT1aN0M0 RCC. The present study was undertaken to identify predictors for recurrence in patients with pT1aN0M0 RCC. We reviewed the clinicopathological factors of 133 patients with pT1aN0M0 RCC who underwent radical or partial nephrectomy at the Department of Urology, National Defense Medical College (Saitama, Japan). Clinicopathological factors, including age, gender, tumor size, histological subtype, tumor grade, microvascular invasion, histological tumor necrosis, C-reactive protein levels and performance status were reviewed. These factors were compared between patients with and without postoperative recurrence. Recurrence-free survival (RFS) and cause-specific survival (CSS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed to determine independent factors predicting recurrence in patients with pT1aN0M0 RCC. The 5-year RFS and CSS rates were 97.2 and 99.1%, respectively. When clinicopathological factors were compared between patients with and without recurrence, tumor size (P=0.0390) and percentage of tumor necrosis (P<0.0001) were significantly different between groups. All patients with recurrence had primary lesions ≥3 cm. By univariate analysis, tumor size (P=0.0379) and the presence of tumor necrosis (P=0.0319) were significant predictors for recurrence; tumor necrosis was also an independent predictor for recurrence (P=0.0143). In patients with pT1b tumors ≤5 cm (recurrence rate, 16.8%; n=48), the percentage of tumor necrosis was significantly higher in patients with recurrence compared with those without (P=0.0261). This suggests that tumor necrosis may be an important predictor for recurrence in small RCCs. Although recurrence is rare in pT1a RCC, the presence of tumor necrosis may be an important predictor for recurrence. Particularly, patients presenting with pT1a RCC with histological tumor necrosis should undergo careful follow-up.

Abstract
The prognosis of patients with renal cell carcinoma (RCC) and liver metastasis (LM) is poor. We evaluated the clinical characteristics, prognosis and prognostic factors of RCC patients with LM. A total of 25 patients who underwent radical or partial nephrectomy (Nx) for RCC between November, 1980 and April, 2013 at the National Defense Medical College, Tokorozawa, Saitama, Japan, with LM at initial presentation or following Nx, were included in this study. The association between prognosis following development of LM and clinicopathological parameters was analyzed. The Cox proportional hazards regression model was used to identify prognostic predictors. The median cancer-specific survival (CSS) following LM diagnosis was 10.6 months. The presence of sarcomatoid differentiation, Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, C-reactive protein ≥1.0 mg/dl, corrected calcium ≥10 mg/dl and presence of multiple organ metastases, were identified as CSS predictors. The multivariate analysis identified ECOG PS ≥2 as an independent CSS predictor. Nine patients survived for >20 months following LM diagnosis and 1 patient, who received treatment with tyrosine kinase inhibitors (TKIs) for LM, exhibited stable disease for 5 years. Nine patients underwent local LM treatment. Two patients, who underwent hepatic resection, survived for 55.1 and 22 months, respectively. In conclusion, RCC patients with LM may benefit from local LM treatment if they have a limited number of metastases in addition to LM and if their ECOG PS is satisfactory. Indeed, a proportion of RCC patients with LM benefit from TKI therapy. Furthermore, RCC patients with LM and ECOG PS ≥2 apparently have a poor prognosis, regardless of local or systemic therapies.

Impact of increased erythropoietin receptor expression and elevated serum erythropoietin levels on clinicopathological features and prognosis in renal cell carcinoma. Exp Ther Med 2012; 3:937-944.

Abstract
Erythropoietin (EPO) expression and EPO receptor (EpoR) expression have been demonstrated in various malignant tumors. EPO-EpoR signaling can activate several downstream signal transduction pathways that enhance tumor aggressiveness. The present study was undertaken to evaluate the impact of overexpression of EpoR and elevated serum EPO (sEPO) levels on the clinicopathological features and prognosis of patients with renal cell carcinoma (RCC). EpoR expression was evaluated immunohistochemically in 56 patients. Tumors with a staining intensity greater than that of surrounding proximal tubules were defined as tumors with high EpoR expression. The association between EpoR expression levels and various clinicopathological factors was analyzed. sEPO levels were determined in 138 patients and its correlation to clinicopathological factors was also analyzed, and EpoR expression was determined in surgical specimens removed from 47 of those 138 patients. Patients with high EpoR expression and patients with sEPO elevation had clinicopathological features less favorable than those of other patients. Tumors demonstrating high EpoR expression had a significantly higher number of Ki-67-positive cells compared to those with low EpoR expression. Tumor assemblies in microvessels demonstrated high EpoR expression. Patients whose tumors demonstrated high EpoR expression and those with sEPO elevation had a significantly lower survival rate compared to other patients, and patients with both high EpoR expression and sEPO elevation had an extremely poor prognosis. Microvascular invasion was an independent factor associated with sEPO elevation, suggesting that EPO-EpoR signaling might be important in RCC metastasis. EPO-EpoR signaling may be involved in tumor growth and progression in RCC and the combination of EpoR expression and sEPO levels may effectively predict clinical outcome.

Abstract
PURPOSE Preoperative C-reactive protein is a strong predictor of recurrence and prognosis in patients with renal cell carcinoma while postoperative C-reactive protein reportedly predicts survival in patients with metastatic renal cell carcinoma. We evaluated the impact of postoperative C-reactive protein on recurrence and prognosis in patients with N0M0 clear cell renal cell carcinoma. MATERIALS AND METHODS We defined increased preoperative C-reactive protein as 1 mg/dl or greater and postoperative C-reactive protein normalization as at least 1 postoperative measurement of less than 0.3 mg/dl. We reviewed the records of 263 patients with N0M0 clear cell renal cell carcinoma who underwent nephrectomy, and in whom preoperative and postoperative C-reactive protein values were available. We used multivariate analysis to identify independent factors predicting recurrence and prognosis. We also evaluated C-reactive protein at recurrence and its impact on survival. RESULTS Increased preoperative C-reactive protein and nonnormalization of postoperative C-reactive protein were associated with worse clinicopathological factors. Postoperative C-reactive protein nonnormalization, increased preoperative C-reactive protein, microvascular invasion and histological tumor necrosis were independent predictors for recurrence. Risk stratification using these factors effectively predicted the possibility of recurrence. Anemia, thrombocytosis and postoperative C-reactive protein nonnormalization were independent predictors of overall survival. Postoperative followup revealed recurrence in 50 patients. The 3-year survival rate in patients with C-reactive protein 0.3 mg/dl or greater at recurrence was significantly lower than that in patients with less than 0.3 mg/dl at recurrence (47.3% vs 81.6%). CONCLUSIONS Nonnormalization of postoperative C-reactive protein is a strong predictor of recurrence and prognosis. Patients with C-reactive protein 0.3 mg/dl or greater at recurrence might not survive as long as those with C-reactive protein less than 0.3 mg/dl at recurrence.
