Prognostic Role of C-Reactive Protein In Urological Cancers: A Meta-Analysis.

ABSTRACT: Growing evidence suggests serum C-reactive protein (CRP) can serve as a prognostic marker in urological cancers. However, some studies yield contradictory results. Our objective was to determine the relationship between baseline serum CRP and survival outcome in urological cancers. We searched PubMed and EMBASE databases until October 2014 without language restrictions. 44 independent studies investigating the association between baseline serum CRP and cancer-specific survival (CSS) or overall survival (OS) were selected. High CRP yielded a worse survival in renal cell carcinoma, prostate cancer, bladder cancer, and upper urinary tract urothelial carcinoma. Combined results of meta-analyses indicated that CRP was a prognostic factor in urological cancers (CSS: p < 0.01; OS: p < 0.01). Subgroup analyses confirmed the significant association between CRP and prognosis, regardless of race and cutoff value of CRP. Specifically, prognostic impact of CRP was also noted in patients with localized RCC treated with nephrectomy (CSS: p < 0.01) and metastatic RCC treated with molecular-targeted therapy (OS: p < 0.01). In conclusion, serum CRP is an independent prognostic factor in urological cancers and risk stratification by serum CRP level could be helpful for prognostic assessment.

Project description:IntroductionThe lymphocyte-C-reactive protein ratio (LCR) is a new immunoinflammatory score and prognostic marker, but the relationship between this index and the prognosis of colorectal cancer patients remains controversial.Therefore, aim of the study was to assess the relationship between LCR and prognosis for colorectal cancer patients through a systematic evaluation and meta-analysis.MethodsWe systematically searched PubMed, EMBASE, Web of Science, and Cochrane Library databases for randomized controlled studies and observational studies on the relationship between LCR and prognosis of colorectal cancer patients, all searched from the date of database creation to January 6, 2022.Our primary endpoints observed were overall survival (OS) and disease-free survival (DFS) of colorectal cancer patients, and secondary observables were basic characteristics of included studies, such as country, study duration, sample size, LCR threshold, and pathological characteristics of patients in each study, such as degree of differentiation, gender, tumor location, T stage, and lymphatic metastasis.ResultsA total of 10 case-control studies including 7068 patients were included. Meta-analysis results showed that overall survival (OS) and disease-free survival (DFS) were worse in colorectal cancer patients with lower levels of LCR (HR=0.44, 95% CI=0.38-0.52, P<0.001; HR=0.56, 95% CI=0.41-0.76, P< 0.001).Subgroup analysis based on country, study length, sample size, and LCR threshold showed that lower levels of LCR were all associated with poorer OS (P < 0.05). Regarding pathological characteristics, patients in the low LCR group were generally poorly differentiated (OR=1.79, 95% CI=1.55-2.07, P<0.001), while there was no significant relationship with gender, tumor location, T stage, and lymphatic metastasis (P>0.05).Discussion/conclusionLCR can be used as a prognostic marker for colorectal cancer patients, and patients with lower levels of LCR may have a poor prognosis. Due to the limitation of the number and quality of the included studies, the above findings need to be validated by more high-quality studies.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42022296563.
