Abstract BACKGROUND A combination of clinical characteristics, radiological findings and tissue markers is used in the assessment of glioblastoma prognosis and prediction of treatment response. The value of routine blood tests as a tool of prognosis has been a subject of debate. In addition to increased complication rate in subsequent resections and radiological uncertainty in treatment monitoring, there is a need to monitor tumor markers in a minimally invasive manner, as molecular characterization becomes more important in the management of glioblastoma. The objective of this review is to evaluate the prognostic value of any blood marker during the course of disease and treatment in glioblastoma. METHODS We researched Pubmed and Embase for clinical studies including cohort studies and randomized controlled trials that included at least 10 adult patients and blood testing during course of disease. We extracted data on clinically relevant endpoints, i.e. overall survival (OS) or progression-free survival (PFS), in accordance with the PRISMA statements. RESULTS The search strategy yielded 6389 unique articles, of which 150 met the inclusion criteria. 37 studies found an association between survival outcomes and pre-operative markers including complete blood count (erythrocytes and leukocytes with differentiation characteristics), inflammatory markers (erythrocyte sedimentation rate and C-reactive protein), coagulability markers (prothrombin time, activated partial thromboplastin time and D-dimer), albumin, lactate dehydrogenase and glucose. Furthermore, 10 studies reported a correlation between changes in platelets, erythrocytes and leukocytes during course of disease and treatment and OS. Finally, serum and plasma levels of markers including various proteins, microRNAs and microvesicles were associated with PFS and OS. CONCLUSION The results of this study suggest that routine and specialized blood tests provide additive information on OS and PFS in glioblastoma. These promising findings highlight the need for further investigation of blood testing for biomarker evaluation.

BACKGROUND: Mucosal healing has been proposed as the therapeutic end point in the treatment of patients with ulcerative colitis (UC).OBJECTIVE: To investigate the relationship between physician global assessment (PGA) and laboratory blood tests (complete blood count, ferritin, C-reactive protein, albumin) and endoscopic findings in UC to determine whether they could be adequate surrogates for endoscopy.METHODS: A retrospective chart review of patients known to have UC from July 2008 to November 2012 was performed at the Health Sciences Centre, Winnipeg, Manitoba. Patients included individuals with UC who underwent colonoscopy within one month of clinic assessment. Blood tests were standard at the time of colonoscopy. Patients presenting through the emergency department, those with colonoscopies performed outside the authors’ institution, or whose colonoscopies and clinical assessments were undertaken more than one month apart were excluded. The PGA was used to determine disease activity in patients before colonoscopy. The Ulcerative Colitis Endoscopic Index of Severity, a validated scoring system to rate endoscopic disease severity in ulcerative colitis, was adapted.RESULTS: A total of 154 patients (mean [± SD] age 44±15.7 years) with UC were identified including 82 (53%) men. Mean hemoglobin level was 139 g/L, mean platelet level was 296×109/L, mean ferritin level was 102 μg/L, mean C-reactive protein level was 10 mg/L and mean albumin level was 40 g/L. Using endoscopy as the ‘gold standard’ for assessing UC activity (moderate-severe), abnormalities in laboratory parameters and PGA were both highly specific but not sensitive for identifying individuals with at least moderately active endoscopic disease. The PGA had higher positive and negative predictive values than the laboratory parameters.CONCLUSION: Neither blood tests nor PGA could replace endoscopy for assessing mucosal healing. When patients experienced active symptoms and abnormal serum markers, they were highly likely to have abnormal endoscopy. However, inactive symptoms or normal laboratory values did not preclude having active endoscopic disease.

Background: Disseminated Kaposi sarcoma (DKS) is present in patients with advanced HIV infection in whom co-infection with other opportunistic pathogens can occur. Bone marrow (BM) aspirate and biopsy comprises a robust diagnostic tool in patients with fever, cytopenias, and abnormal liver tests. However, the yield in patients with DKS has not been determined. Objective: The aim of this study was to evaluate the utility of BM aspirate and biopsy in patients with DKS. Methods: We included 40 male patients with recent diagnosis of DKS. BM aspirate and biopsy was performed as part of the workup to rule out co-infections. Results: In four patients, Mycobacterium avium complex (MAC) was recovered from culture. In another four patients, intracellular yeasts were observed in the Grocott stain, diagnosed as Histoplasma. The yield of BM was calculated in 20%. Only 12 patients (30%) had fever and 11 (27.5%) had pancytopenia. Alkaline phosphatase (ALP) above normal values and C-reactive protein (CRP) were higher in patients with positive results for BM than in those with negative results (63% vs. 21.9%, and 3.0 vs. 1.2 mg/L; p = 0.03 in both comparisons). No differences were found on comparing complete blood-count abnormalities. Conclusion: We recommend performing a BM aspirate for stains, culture, and biopsy in all HIV patients with DKS, as this will permit the early diagnosis of co-infections and prevent further complications in those who receive chemotherapy.

Purpose. The prognostic value of a new scoring system, termed F-NLR, that combines pretreatment fibrinogen level with neutrophil-lymphocyte ratio has been evaluated in various cancers. However, the results are controversial. The purpose of this study was to comprehensively analyze the prognostic value of F-NLR score in patients with cancers. Methods. An integrated search of relevant studies was conducted by screening the PubMed and Embase databases. Pooled hazard ratios, with 95% confidence intervals (CIs), for overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) were calculated to estimate the prognostic significance of F-NLR score in patients with various tumors. A random effects model was used for comprehensive analysis, and subgroup and meta-regression analyses were used to explore sources of heterogeneity. Results. Thirteen articles reporting data from of 4747 patients were included in the study. Pooled analysis revealed that high F-NLR score was significantly associated with poor OS ( HR = 1.77 ; 95% CI, 1.51–2.08) and poor DFS/PFS ( HR = 1.63 ; 95% CI, 1.30–2.05). Subgroup and meta-regression analyses did not alter the prognostic role of F-NLR score in OS and DFS/PFS. Conclusions. Increased F-NLR score is significantly associated with poor prognosis in patients with cancers and can serve as an effective prognostic indicator.

Anemia Of Inflammation

Background:Anemia of inflammation (AI) and iron deficiency anemia (IDA) are the two most prevalent forms of anemia in patients with rheumatoid arthritis (RA). Diagnosis becomes challenging if AI is associated with true ID (AI/ID), as there is still a lack of a gold standard for differentiation between AI and AI/ID. However, as therapies to overcome anemia differ, proper diagnosis and understanding of underlying pathophysiological regulations are necessary.Objectives:The aim of the study was to evaluate the clinical efficiency of hepcidin, a key regulator of iron metabolism, in the diagnosis of IDA, as well as the differential diagnosis of AI/ID and AI in patients with RA.Methods:The study was undertaken 96 patients with RA, 67 of them were diagnosed anemia according to WHO criteria (104,3±21,4 g/l). Anemic patients and anemia-free patients with RA (n=29) were comparable (p>0.05) in age (44.4±14.8 and 49.8±9.3 years), disease duration (73.5±65.4 and 59.8±48.3 months) and DAS28 (6.3±1.6 and 5.9±1.9). All cases were subjected to following tests: complete blood count with peripheral smear, serum C-reactive protein, serum interleukin-6, iron studies, serum soluble transferrin receptor (sTfR), and serum hepcidin. Patients with RA and anemia were divided two groups: 25 patients with IDA and 42 - with AI. The AI cases were subdivided into pure AI and AI with coexistent ID (n=15).Results:The mean serum hepcidin concentration was significantly increased in pure AI patients (123.85±25.8 ng/mL) as compared to those in IDA patients (63.9±22.8 ng/mL, P < 0.05) and anemia-free patients with RA (88.1±39.09 ng/mL). Also, compared to pure AI patients [normal sTfR levels (<3 µg/mL)], the serum hepcidin concentration was reduced significantly in AI patients with ID [high sTfR levels (≥3 µg/mL)] with a mean of 79.0±23.97 ng/mL.Conclusion:Hepcidin measurement can provide a useful tool for differentiating AI from IDA and also help to identify an iron deficiency in AI patients. This might aid in the appropriate selection of therapy for these patients.Disclosure of Interests:None declared

Patients with coronavirus disease 2019 (COVID-19) develop severe respiratory failure within a short period during the clinical course. It is essential to predict respiratory deterioration in the short term. We investigated the use of inflammatory markers to predict respiratory distress within three days from their analysis in COVID-19 patients. This retrospective observational study included 81 patients admitted with COVID-19. Patients were divided into two groups according to whether the maximum fraction of inspired oxygen (FiO2) for three days from the blood marker measurements was ≥0.4 (high FiO2 group; HFG) or <0.4 (low FiO2 group; LFG). Interleukin-6 (IL-6), C-reactive protein (CRP), lactate dehydrogenase (LDH), white blood cell, D-dimer, and creatinine levels were compared between the two groups. The levels of all markers were significantly higher in HFG patients. Areas under the receiver operating characteristic curve of IL-6, CRP, and LDH had high values of 0.85, 0.82, and 0.81, respectively. The odds ratio of IL-6 which was crude and adjusted for dexamethasone administration initiated before laboratory measurement, showed the high value of 29.1 (5.6–295.6) and 53.9 (4.5–3242.8), respectively. IL-6 can be used as a reliable marker for predicting respiratory illness within three days after assessment.

Abstract OBJECTIVE To evaluate the clinical factors related to the prognosis of basal ganglia germ cell tumors. METHODS A retrospective analysis of 52 cases of the basal ganglia germ cell tumors treated from January 2009 to January 2019 in the department of oncology of Guangdong Sanjiu Brain Hospital. The median age: 12 years (range: 5–32), The median course of disease: 11.7 months (range: 1–54). Thirteen cases were diagnosed by biopsy and 39 cases were diagnosed by elevated tumor markers. There were 31 patients (59.6%) diagnosed with germinomas and 21 patients (40.4%) with non-germ germ cell tumors. Univariate and multivariate survival analysis was performed. RESULTS To October 15, 2019, the median follow-up time was 30.4 months (range 2–124 months). The 5-year survival rate was 85%, and the 5-year progression-free survival rate was 84%. Multivariate analysis found whether serum AFP was greater than 100mIU / ml, (with HR: 11.441,95% CI: 2.09–47.66, P = 0.005),the degree of surgical resection(with HR 5.323 (1.19–23.812), P = 0.029), PD as the effect of radiotherapy (HR: 16.53, (1.19–23.81), P = 0.001) were independent prognostic factor affecting survival. CONCLUSION The pathological type, degree of surgical resection, and response to initial treatment can all affect survival.
