PURPOSE To evaluate the effect of transcatheter arterial chemoembolization (TACE) under the guidance of contrast-enhanced ultrasound (CEUS) in patients with advanced hepatocellular carcinoma (HCC). METHODS One hundred and sixty patients with HCC admitted to Cangzhou Central Hospital from April 2015 to April 2017 were enrolled. The clinical data were retrospectively analyzed. Seventy-five patients who underwent TACE according to CEUS results were selected as the observation group. The remaining 85 cases that underwent digital subtraction augiography (DSA) angiography-guided TACE were selected as the control group and were intravenously infused with 15 mg of Endostar+500 mL of normal saline once a day for 3 consecutive days (Endostar 30 mg was reperfused during the operation). Both groups were re-contrasted at 1 month (T2) and 3 months (T3) to determine whether TACE was performed again. The numbers of TACEs re-performed were recorded. Color Doppler energy imaging was used to observe the neovascularization of thvely inhibit tumor angiogenesis, control tumor progression, and prolong the survival of patients, which is conducive to the prognosis of patients.PURPOSE Leukemia causes annually a significant number of deaths. The main objective of this study was to investigate the anticancer properties of piperine and curcumin against HL60 leukemia cells and to elucidate the underlying mechanism. METHODS Antiproliferative effects were assessed by WST-1 cell viability assay. Cell apoptotic effects were studied by DAPI staining assay. Annexin V/propidium iodide (PI) assay was used to assess apoptosis. Electron microscopy was used for detection of autophagy and flow cytometry for cell cycle analysis, while transwell migration assay was used to study the effects on cell migration and invasion. Protein expression was estimated by western blot. RESULTS The results showed that both piperine and curcumin inhibited significantly the growth of the HL60 cells and exhibited an IC50 of 25 and 30 µM respectively. Further, it was observed that the anticancer effects of piperine and curcumin were due to the induction of mitochondrial-mediated apoptosis which was also associated with enhancement of the Bax expression. Transmission electron microscopy also showed that both curcumin and piperine induced autophagy in the HL-60 leukemia cells. Flow cytometry showed that piperine and curcumin also caused arrest of the HL-60 cells at the S-phase of the cell cycle. Finally wound healing and transwell assays showed that piperine and curcumin suppressed the migration and invasive potential of the HL60 cells. CONCLUSIONS The present study reveals that piperine and curcumin exhibit significant antitumor activity in human leukemia HL60 cells via multiple mechanisms and may prove promising in the development of systemic therapy for leukemia.PURPOSE This study aimed to investigate the expression and the prognostic value of CIP2A in multiple myeloma (MM). METHODS The expression levels of CIP2A was measured in 33 newly diagnosed MM patients (at presentation and after 4 cycles of Bortezomib-Dexamethazone (BD) regimen) and 15 healthy controls by real time quantitative polymerase chain reaction (QRT-PCR). RESULTS CIP2A expression was upregu¬lated in MM patients compared to controls. There was a significant reduction in CIP2A expression after treatment with BD regimen. Patients with expression levels ≤ 16.45 EU (expression unit) were more likely to respond to BD regimen (23 patients out of 23) than those with expression level >16.45 (6 patients out of 10) (p=0.005). Lower progression-free survival (PFS) (16.7%) was observed among patients with high CIP2A expression levels compared to 50% PFS in patients with lower CIP2A expression levels (p=0.006). CONCLUSION CIP2A is upregulated in MM and bortezomib downregulated its expression. High CIP2A level is associated with shorter PFS and poor response to BD in MM. Therefore, beside its value as a poor prognostic indicator in MM, CIP2A suppression might be a fruitful future targeted therapeutic agent aiming to improve the outcome in MM.PURPOSE The current study aimed at investigating the anticancer effects of plant-based flavone Baicalein against the thyroid cancer. METHODS Cell viability was assessed using MTT assay. Flow cytometric-based estimation of cell cycle analysis was done for determining the cancer cell phase distribution. DAPI staining method followed by fluorescent microscope examination was used for inferring the cancer cell apoptosis. Transmission electron microscopy (TEM) was used for detection of autophagosomes. Western blotting was done for protein concentration estimation. RESULTS Baicalein induced dose-dependent decline in proliferation of MDA-T68 thyroid cancer cells, while the reduction of cell proliferation was surprisingly lower for normal thyrocytes. IC50 of 10μM was estimated against cancer cells. Baicalein induced cell apoptosis in a concentration-dependent manner. Pimicotinib chemical structure Induction of apoptosis was attributed to increase in apoptotic protein concentration and signal was mediated through change Bax/Bcl-2 ratio. The autophagic cell death occurred in cancer cells when treated with Baicalein. The mechanism of cell death was inferred as modulation of NF-kB signaling pathway. Baicalein was also seen to induce mitotic cell cycle arrest in thyroid cancer cells by reducing the concentration of Cyclin B1 mitotic protein. CONCLUSION The results of current study suggest Baicalein as an important anticancer agent against thyroid cancer. Future research to further investigate and enhance the effects of Baicalein against thyroid cancer is needed.PURPOSE Persistent/recurrent disease in the neck is frequent in patients with papillary thyroid cancer (PTC). The goal of this study was to evaluate the efficacy of the reoperation and radioiodine (RAI) treatment for persistent/recurrent disease after the initial treatment. METHODS A total of 30 patients (13 M/17 F) with PTC were enrolled in this study. All had been submitted to total thyroidectomy for PTC and subsequently to reoperation for local persistent/recurrent disease. All had received RAI, before and/or after reoperation. The mean age at initial thyroidectomy and cancer diagnosis was 41.4±15.2 years. Initial T status was T1 in 22 cases (73.3%), T2 in 4 cases (13.3%) and T3 in 4 cases (13.3%). Initial N status was N0 in 2 cases (6.6%), N1 in 15 cases (50%) and Nx in 13 cases (43.3%). RESULTS Reoperation reduced the mean stimulated thyroglobulin (stimTg) serum concentration from 76.1±165.5 ng/mL to 20.1±28.8 ng/mL, p=0.002. The RAI treatment provided to 19 patients after reoperation reduced further the stimTg values from 28.6±32.4 ng/mL after reoperation, to 11.3±20.4 ng/mL, p=0.003. According to the dynamic risk stratification after the reoperation 7 patients (23.3%) had excellent response, 4 (13.3%) had biochemically incomplete response, 9 (30.0%) had indeterminate response and 10 (33.3%) had still structural incomplete response. CONCLUSION Surgery for local persistent/recurrent disease in papillary thyroid carcinoma reduces tumor burden, improves the biochemical and structural disease. Administration of therapeutic RAI after lymph node resections appears to further improve biochemical disease.PURPOSE The incidence of histologically proven lymph node metastases (LNM) in papillary thyroid carcinoma (PTC) reaches 80%. According to different guidelines surgical management in clinically N0 (cN0) patients with PTC remains controversial. The purpose of this study was to investigate if sentinel lymph node biopsy (SLNb) using methylene blue dye is accurate in the detection of LNM in the lateral neck compartment in cN0 patients with PTC. METHODS Enrolled were 153 cN0 patients with PTC. All underwent total thyroidectomy with central neck dissection and SLNb in the lateral neck compartment, using methylene blue dye as marker. Selective modified radical neck dissection was performed in cases of metastatic SLNs. RESULTS Neck LNMs were histologically verified in 40.9% of the cases. Predictive factors for LNM were males, younger than 45 years, tumors greater than 1cm, capsular and vascular invasion. The central neck compartment of LNM was predictive for lateral LNM in 80.5% of the cases. LNM were confirmed in 24% of SLNs in the lateral neck compartment, which were over 56% predictive of LNM to other dissected lateral LN. SLN identification rate (IR) was 91.8%. Sensitivity, specificity, positive value (PPV) and negative predictive value (NPV) were 85.7, 96.7, 88.3 and 95.9%, respectively. The overall accuracy of the method was 94.3%, with probability of 91.2% (ROC AUC, 95% CI; 84.2-98.3). CONCLUSION The proposed method of SLN biopsy using methylene blue dye is feasible, safe and accurate in the detection of LNM in the lateral neck compartment and may help in the decision to perform selective modified radical neck dissection in cN0 patients with PTC.PURPOSE To investigate the prognostic value of pre-treatment neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and hemoglobin level in patients treated with definitive chemoradiotherapy (CRT) for nasopharyngeal carcinoma. METHODS We retrospectively analyzed 97 patients who received definitive CRT for nasopharyngeal cancer. An NLR cut-off value of 4.42 was identified using receiver operating characteristic curve (ROC) analysis, an PLR cut-off value of 128.6 was identified using ROC analysis and a hemoglobin cut-off value of 13g/dl was identified using ROC analysis with overall survival (OS) as an endpoint. RESULTS The 5-year progression-free survival (PFS) and overall survival (OS) for all patients were 67.1% and 72.6%, respectively. The patients with a high NLR (20.6%) had a significantly lower 5-year OS than those with a low NLR (79.4%) (OS 46.9% vs. 79.7%, p less then 0.001). The patients with a high PLR (66.3%) had a borderline significant lower 5-year OS than those with a low PLR (32.7%) (OS 66.1% vs. 87.9%, p=0.055). The patients with a low hemoglobin (18.4%) had a significantly lower 5-year OS than those with a high hemoglobin (80.6%) (OS 46.6% vs. 78.9%, p less then 0.001). In univariate analysis, older age, IMRT technique, low hemoglobin and high NLR were prognostic factors. In multivariate analysis, high NLR, low hemoglobin and older age remained independent prognostic factors for OS. CONCLUSIONS Nasopharyngeal cancer tends to be more aggressive in patients with a high NLR and low hemoglobin. These patients should be treated more aggressively, given their unfavorable prognosis.PURPOSE Laryngeal cancer is one of most common and aggressive head and neck cancers with poor prognosis and great necessity for improvement of treatment modalities. MicroRNAs (miRs) are among the most investigated molecules recently due to their potential as diagnostic and prognostic biomarkers in cancer. The purpose of our study was to explore the association of certain clinicopathological features with the expression levels of some known cancer associated non-coding (nc) RNAs miR-21 and miR-31 in both of their isoforms, miR-145-5p, miR-55-5p, miR-196a-5p, miR-210-3p, miR-221-3p, miR-222-3p, miR-424-5p, lncRNA MALAT1 and lncRNA HOTAIR. METHODS Expression levels of the chosen markers were investigated in laryngeal squamous cell carcinoma (LSCC) and normal samples in 82 Bulgarian patients via RT-qPCR, and the results were analyzed with SPSS v23.0 statistical software. RESULTS All of the explored ncRNAs were significantly deregulated in LSCC samples, suggesting their involvement in laryngeal carcinogenesis. New significant association were found between the expression levels of miR-21-5p, miR-222-3p, HOTAIR and family history.
