PurposeA 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.MethodsMeSH (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).Results271 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.ConclusionsA 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.
ObjectivesTo evaluate the performance of MRI for diagnosis of breast cancer in non-calcified equivocal breast findings.Materials and MethodsWe performed a systematic review and meta-analysis of peer-reviewed studies in PubMed from 01/01/1986 until 06/15/2015. Eligible were studies applying dynamic contrast-enhanced breast MRI as an adjunct to conventional imaging (mammography, ultrasound) to clarify equivocal findings without microcalcifications. Reference standard for MRI findings had to be established by histopathological sampling or imaging follow-up of at least 12 months. Number of true or false positives and negatives and other characteristics were extracted, and possible bias was determined using the QUADAS-2 applet. Statistical analyses included data pooling and heterogeneity testing.ResultsFourteen out of 514 studies comprising 2,316 lesions met our inclusion criteria. Pooled diagnostic parameters were: sensitivity (99%, 95%-CI: 93–100%), specificity (89%, 95%-CI: 85–92%), PPV (56%, 95%-CI: 42–70%) and NPV (100%, 95%-CI: 99–100%). These estimates displayed significant heterogeneity (P<0.001).ConclusionsBreast MRI demonstrates an excellent diagnostic performance in case of non-calcified equivocal breast findings detected in conventional imaging. However, considering the substantial heterogeneity with regard to prevalence of malignancy, problem solving criteria need to be better defined.
Cancer-anorexia cachexia animal models are numerous. No one is ideal. The choice should depend on the research question. To investigate cancer-anorexia cachexia independent of pro-inflammatory cytokine effects, the MAC16 ADK and XK1 are useful. MAC16 ADK helps study the host's tumor metabolic effects, independent of any anorexia or inflammation. XK1 is both anorectic and cachectic, but data about it is limited. All other models induce a host inflammatory response. The Walker 256 ADK and MCG 101 are best avoided due to excessive tumor growth. Since individual models do not address all aspects of the syndrome, use of a combination seems wise. Suggested combinations: MAC16-ADK (non-inflammatory and non-anorectic) with YAH-130 (inflammatory, anorectic, and cachectic), Lewis lung carcinoma (slow onset anorexia) or prostate adenocarcinoma (inflammatory, anorectic but not cachectic) with YAH-130.
Cancer anorexia cachexia syndrome is frequent yet still a not well understood cancer-related problem. The pathophysiology of cancer cachexia is multifactorial. It is suggested to be the result of tumor-host interactions and studies of the disturbances seen during cancer anorexia cachexia syndrome, such as anorexia, hyper-metabolism, tissue wasting, metabolic abnormalities, and hormonal changes, all point to the involvement in one way or another of one key factor: cytokines. The purpose of this review is to summarize the latest developments in the field of cytokines and their role in cancer anorexia cachexia syndrome. The emphasis is on the role of cytokines in anorexia and tissue wasting.
plays a role in lymphoma progression, analysis of which may provide useful information for assessing prognosis. Meanwhile, data of the role of specific circulating lymphocyte subsets as host immune factor in the progression of ENKTL is limited. This study aims to investigate the clinical correlation and distribution of circulating absolute CD4 + T cell counts (ACD4C) in ENKTL. The distribution and prognostic value of ACD4C at diagnosis was analyzed.Results: The result showed that low ACD4C at diagnosis was significantly associated with stage III/IV (P = 0.001), B symptoms (P = 0.020), elevated serum lactate dehydrogenase (LDH) (P < 0.001), regional lymphadenopathy (P = 0.015), high-intermediate and high-riskInternational Prognosis Index (IPI) (P < 0.001) and Korean Prognostic Index (KPI) (P < 0.001). As well, we also found that low ACD4C have significant link to decreasing monocytes (P = 0.001), anemia (P = 0.049) and thrombocytopenia (P = 0.014). There were significant differences in both overall survival (OS) (P < 0.001) and progressionfree survival (PFS) (P < 0.001) between ACD4C < 0.3 × 10 9 /L cohort and ACD4C ≥ 0.3 × 10 9 /L cohort ( ABSTRACT 391
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
