| 1 | Cytopathologic diagnosis of fine needle aspiration biopsies of thyroid nodules显示文摘Fine-needle aspiration(FNA) cytology is an important diagnostic tool in patients with thyroid lesions.Several systems have been proposed for the cyropathologic diagnosis of the thyroid nodules.However cases with indeterminate cytological findings still remain a matter of debate.In this review we analyze all literature regarding Thyroid Cytopathology Reporting systems trying to identify the most suitable methodology to use in clinical practice for the preoperative diagnosis of thyroid nodules.A review of the English literature was conducted,and data were analyzed and summarized and integrated from the authors' perspective.The main purpose of thyroid FNA is to identify patients with higher risk for malignancy,and to prevent unnecessary surgeries for benign conditions.The Bethesda System for Reporting Thyroid Cytopathology is the most widely used system for the diagnosis of thyroid FNA specimens.This system also contains guidelines for the diagnosis and treatment of indeterminate or suspicious for malignancy cases.In conclusion,patients who require repeated FNAs for indeterminate diagnoses will be resolved by repeat FNA in a percentage of 72%-80%. | Evangelos P Misiakos Niki Margari Christos Meristoudis Nickolas Machairas Dimitrios Schizas Konstantinos Petropoulos Aris Spathis Petros Karakitsos Anastasios Machairas | 2016 | World Journal of Clinical Cases2016，4，2： | 12 |
| 2 | TYMS/KRAS/BRAF molecular profiling predicts survival following adjuvant chemotherapy in colorectal cancer显示文摘BACKGROUND Patients with stage II-III colorectal cancer (CRC) treated with adjuvant chemotherapy, gain a 25% survival benefit. In the context of personalized medicine, there is a need to identify patients with CRC who may benefit from adjuvant chemotherapy. Molecular profiling could guide treatment decisions in these patients. Thymidylate synthase (TYMS) gene polymorphisms, KRAS and BRAF could be included in the molecular profile under consideration. AIM To investigate the association of TYMS gene polymorphisms, KRAS and BRAF mutations with survival of CRC patients treated with chemotherapy.METHODS A retrospective study studied formalin-fixed paraffin-embedded tissues (FFPEs) of consecutive patients treated with adjuvant chemotherapy during January/2005-January/2007. FFPEs were analysed with PCR for the detection of TYMS polymorphisms, mutated KRAS (mKRAS) and BRAF (mBRAF). Patients were classified into three groups (high, medium and low risk) according to 5’UTR TYMS polymorphisms Similarly, based on 3’UTR polymorphism ins/loss of heterozygosity (LOH) patients were allocated into two groups (high and low risk of relapse, respectively). Cox regression models examined the associated 5- year survival outcomes. RESULTS One hundred and thirty patients with early stage CRC (stage I-II: 55 patients;stage III 75 patients;colon: 70 patients;rectal: 60 patients) were treated with surgery and chemotherapy. The 5-year disease free survival and overall survival rate was 61.6% and 73.9% respectively. 5’UTR polymorphisms of intermediate TYMS polymorphisms (2RG/3RG, 2RG/LOH, 3RC/LOH) were associated with lower risk for relapse [hazard ratio (HR) 0.320, P = 0.02 and HR 0.343, P = 0.013 respectively] and death (HR 0.368, P = 0.031 and HR 0.394, P = 0.029 respectively). The 3’UTR polymorphism ins/LOH was independently associated with increased risk for disease recurrence (P = 0.001) and death (P = 0.005). mBRAF (3.8% of patients) was associated with increased risk of death (HR 4.500, P = 0.022) whereas mKRAS (39% of patients) not. CONCLUSION Prospective validating studies are required to confirm whether 2RG/3RG, 2RG/LOH, 3RC/LOH, absence of ins/LOH and wild type BRAF may indicate patients at lower risk of relapse following adjuvant chemotherapy. | Anastasios Ntavatzikos Aris Spathis Paul Patapis Nikolaos Machairas Georgia Vourli George Peros Iordanis Papadopoulos Ioannis Panayiotides Anna Koumarianou | 2019 | World Journal of Gastrointestinal Oncology2019，11，7： | 5 |
| 3 | Integrating TYMS, KRAS and BRAF testing in patients with metastatic colorectal cancer显示文摘AIM To investigate the impact of thymidylate synthase(TYMS), KRAS and BRAF in the survival of metastatic colorectal cancer(m CRC) patients treated with chemotherapy. METHODS Clinical data were collected retrospectively from records of consecutive patients with m CRC treated with fluoropyrimidine-based chemotherapy from 1/2005 to 1/2007. Formalin-fixed paraffin-embedded tissues were retrieved for analysis. TYMS genotypes were identified with restriction fragment analysis PCR, while KRAS and BRAF mutation status was evaluated using real-time PCR assays. TYMS gene polymorphisms of each of the 3' untranslated region(UTR) and 5'UTR were classified into three groups according to the probability they have for high, medium and low TYMS expression(and similar levels of risk) based on evidence from previous studies. Univariate and multivariate survival analyses were performed.RESULTS The analysis recovered 89 patients with m CRC(46.1% de novo metastatic disease and 53.9% relapsed). Of these, 46 patients(51.7%) had colon cancer and 43(48.3%) rectal cancer as primary. All patients were treated with fluoropyrimidine-based chemotherapy(5FU or capecitabine) as single-agent or in combination with irinotecan or/and oxaliplatin or/and bevacizumab. With a median follow-up time of 14.8 mo(range 0-119.8), 85 patients(95.5%) experienced disease progression, and 63 deaths(70.8%) were recorded. The 3-year and 5-year OS rate was 25.4% and 7.7% while the 3-year progression-free survival rate was 7.1%. Multivariate analysis of TYMS polymorphisms, KRAS and BRAF with clinicopathological parameters indicated that TYMS 3'UTR polymorphisms are associated with risk for disease progression and death(P < 0.05 and P < 0.03 respectively). When compared to tumors without any del allele(genotypes ins/ins and ins/loss of heterozygosity(LOH) linked with high TYMS expression) tumors with del/del genotype(low expression group) and tumors with ins/del or del/LOH(intermediate expression group) have lower risk for disease progression(HR = 0.432, 95%CI: 0.198-0.946, P < 0.04 and HR = 0.513, 95%CI: 0.287-0.919, P < 0.03 respectively) and death(HR = 0.366, 95%CI: 0.162-0.827, P < 0.02 and HR = 0.559, 95%CI: 0.309-1.113, P < 0.06 respectively). Additionally,KRAS mutation was associated independently with the risk of disease progression(HR = 1.600, 95%CI: 1.011-2.531, P < 0.05). The addition of irinotecan in 1st line chemotherapy was associated independently with lower risk for disease progression and death(HR = 0.600, 95%CI: 0.372-0.969, P < 0.04 and HR = 0.352, 95%CI: 0.164-0.757, P < 0.01 respectively).CONCLUSION The TYMS genotypes ins/ins and ins/LOH associate with worst prognosis in m CRC patients under fluoropyrimidine-based chemotherapy. Large prospective studies are needed for validation of our findings. | Anastasios Ntavatzikos Aris Spathis Paul Patapis Nikolaos Machairas George Peros Stefanos Konstantoudakis Danai Leventakou Ioannis G Panayiotides Petros Karakitsos Anna Koumarianou | 2017 | World Journal of Gastroenterology2017，23，32： | 4 |
| 4 | Increased levels of circulating platelet-derived microparticles in psoriasis:Possible implications for the associated cardiovascular risk显示文摘AIM To evaluate platelet activation markers in psoriasis patients, compared to controls, and investigate their association with the inflammatory burden of psoriasis.METHODS Forty psoriatic patients without cardiovascular disease,and 12 healthy controls were subjected to measurement of baseline platelet CD62 P, CD63 and CD42 b expression, platelet-leukocyte complexes, i.e., platelet-monocyte complexes(PMC), platelet-neutrophil complexes(PNC) and platelet-lymphocyte complexes, and concentrations of platelet-derived microparticles(PMPs) using flow cytometry. Both larger-size(0.5-0.9 μm) and smallersize(< 0.5 μm) PMPs were determined. Serum interleukin(IL)-12 and IL-17 levels were also measured by enzyme-linked immunosorbent assay. The severity of psoriasis was evaluated by the Psoriasis Area Severity Index(PASI).RESULTS PMP concentrations were significantly higher in psoriasis patients than controls [mean±standard error of mean(SEM): 22±5/μL vs 11±6/μL; P=0.018), for both smaller-size(10±2/μL vs 4±2/μL; P=0.033) and larger-size(12±3/μL vs 6±4/μL; P=0.014) PMPs. Platelet CD62 P, CD63 and CD42 b expression and circulating PMC and PNC were similar between the two groups. Lower circulating PLC were observed in psoriasis patients compared to controls(mean±SEM: 16%±3% vs 23%±6%; P=0.047). Larger-size PMPs were related with IL-12 levels(P<0.001) and smaller-size PMPs with both IL-12 and IL-17 levels(P<0.001). Total PMPs also correlated with IL-12(P<0.001). CD63 expression was positively correlated with both IL-12 and IL-17(P<0.05). Increased PASI score was associated with increased levels of larger-size PMPs(r=0.45; P=0.011) and increased CD63 expression(r=0.47; P<0.01).CONCLUSION PMPs, known to be predictive of cardiovascular outcomes, are increased in psoriasis patients, and associated with high inflammatory disease burden. Enhanced platelet activation may be the missing link leading to cardiovascular events in psoriatic patients. | Evangelia Papadavid Konstantina Diamanti Aris Spathis Maria Varoudi Ioanna Andreadou Kostas Gravanis Kostas Theodoropoulos Petros Karakitsos John Lekakis Dimitrios Rigopoulos Ignatios Ikonomidis | 2016 | World Journal of Cardiology2016，8，11： | 2 |
