The objective was to identify predictors of true negatives in lung nodules (LNs) with computed tomography-guided percutaneous biopsy (CTPB)-based benign pathological results.

We included 90 total patients between January 2013 and December 2017 that had CTPB-based nonspecific benign pathologies and used these patients as a training group to accurately identify true-negative predictors. A validation group of 50 patients from January 2018 to June 2019 to confirm predictor reliability.

CTPB was conducted on 90 LNs from the training group. True-negative and false-negative CTPB-based pathologies were obtained for 79 and 11 LNs, respectively. CTPB-based benign results had a negative predictive value of 87.8% (79/90). Univariate and multivariate analyses revealed younger age (P = 0.019) and CTPB-based chronic inflammation with fibroplasia (P = 0.010) to be true-negative predictors. A predictive model was made by combining these two prognostic values as follows score = -7.975 + 0.112 × age -2.883 × CTPB-based chronic inflammation with fibroplasia (0 no present; 1 present). The area under receiver operator characteristic (ROC) curve was 0.854 (P < 0.001). To maximize sensitivity and specificity, we selected a cutoff risk score of -0.1759. The application of this model to the validation group yielded an area under the ROC curve of 0.912 (P < 0.001).

Our predictive model showed good predictive ability for identifying true negatives among CTPB-based benign pathological results.

To construct an integrated nomogram combining protein induced by vitamin K antagonist-II (PIVKA-II), alpha fetoprotein (AFP) and other clinical factors to detect microvascular invasion (MVI) in early hepatocellular carcinoma (HCC) patients with single nodule.

One hundred and eleven early HCC patients were enrolled in the present study and 43 early HCC patients were diagnosed with MVI. Serum levels of PIVKA-II, AFP and other laboratory indicators were detected. Chi-squared test, t-test and logistic regression were employed in statistic analysis. A nomogram combining independent predictors was constructed and internal validated.

In early HCC patients with MVI, PIVKA-II serum level was significantly higher than those without MVI (385.97 mAU/ml vs 67.08 mAU/ml; P < 0.01), as well as AFP serum level (81.6 ng/mL vs 9.15 ng/mL P = 0.001). PIVAK-II, AFP serum levels and tumor size were independent risk factors for MVI in early HCC, which was employed to develop a logistic regression model. The area under the ROC curve (AUROC) of the model was 0.74 (95%CI 0.65 - 0.84). A nomogram combining PIVKA-II, AFP and tumor size was constructed and calibration curves showed that the model was accurate in predicting the risk of MVI in early HCC patients.

The present study indicates that a preoperative nomogram combining PIVKA-II, AFP and tumor size could estimate the preoperative probability of MVI in early HCC patients, which may help clinicians in choosing treatment options and prognosis evaluation.

The aim of this study was to evaluate the role of BCL6B methylation in the progression of early-stage hepatocellular carcinoma (HCC) after thermal ablation.

This is a retrospective study and written informed consent was obtained from all patients or their legal guardians.

Between October 2008 and December 2013, 73 patients with early-stage HCC within the Milan criteria, who received thermal ablation, were recruited.

Based on methylation-specific polymerase chain reaction, the relationship between BCL6B methylation and patient characteristics and prognosis was analyzed using univariate, multivariate, and Kaplan-Meier analysis.

The median follow-up period was 56 (8-110) months. For the BCL6B unmethylated group, the 1-, 3- and 5-year metastasis and overall survival (OS) rates after thermal ablation were 10.0%, 10.0%, and 40.0% and 100%, 100% and 90.0%, respectively. The 1-, 3-, and 5-year metastasis and OS rates of the methylated group were 23.8%, 66.7% and 88.9% and 66.2%, 71.4% and 41.3%, respectiveland epigenetic therapy for patients with HCC.

BCL6B methylation could be a valuable prognostic factor for metastasis and poor prognosis in early-stage HCC after thermal ablation, which is an independent risk factor for metastasis. Our findings provide insights for combining ablation and epigenetic therapy for patients with HCC.

The aim was to study the changes in thyroid antibody and T lymphocyte subsets after radiofrequency ablation (RFA) of thyroid nodules in patients with autoimmune thyroiditis.

Patients (n = 135) with autoimmune thyroiditis and thyroid nodules were treated by RFA. The indices of thyroid function and thyroid antibody and T lymphocyte subsets were examined preoperation and on the 1

day and the 1

month after ablation. Any complications were recorded.

The software SPSS 17.0.0 (version 2008-8-23) running under Windows 8 was used for statistical analysis. The measurement data were expressed as x ± s, with P < 0.01 indicating a significant difference in the statistical data.

Levels of free triiodothyronine, free thyroxine, and thyroid-stimulating hormone were in the normal range before ablation, and no significant changes occurred on the 1

day or in the 1

month after ablation. The change in the percentage of CD8+T cells and the absolute value of B cells were not statistically significant (P > 0.01-Ab and TPO-Ab levels can be significantly decreased, and the distribution of T lymphocyte subsets can be changed in the short term after ablation.

Small-cell carcinoma is a relatively infrequent pathological variety of esophageal cancer. In this study, a novel nomogram model was developed to evaluate the cancer-specific survival (CSS) and overall survival (OS) of patients with primary esophageal small-cell carcinoma (ESmCC).

In total, 502 patients with primary ESmCC were identified based on data from 1973 to 2015 retrieved from the surveillance, epidemiology, and end results database. Clinical characteristics such as age at diagnosis, gender, race, site, tumor stage, surgery, radiotherapy, and chemotherapy were included for multivariate logistic analyses to predict CSS and OS. Nomogram models for the prediction of CSS and OS in ESmCC patients were tested with the concordance index (C-index) method and calibration curves.

From our multivariate analyses, race, stage, chemotherapy, and radiotherapy, but not surgery, were significantly associated with the CSS of ESmCC patients, while age at diagnosis, stage, chemotherapy, and radiotherapy were signifiall survival, surveillance, epidemiology, and end results.

This study aimed to evaluate the role of serum prostate-specific antigen (PSA) levels and multiparametric magnetic resonance imaging (mpMRI) in the diagnosis of granulomatous prostatitis (GP) induced by intravesical Bacillus Calmette-Guérin vaccine (BCG) therapy in patients with nonmuscle invasive bladder cancer (NMIBC).

We retrospectively analyzed eight patients with bladder cancer who underwent intravesical BCG therapy after transurethral resection of bladder tumor (TURBt) cancer. All these eight patients received 12-core transrectal ultrasound-guided prostate systemic biopsies. Clinical data on PSA with T1-weighted imaging (T1WI), T2WI, diffusion-weighted imaging (DWI), and apparent diffusion coefficient (ADC) on mpMRI were enrolled in the study. H and E and acid-fast staining was performed to pathologically prove GP.

Four of all eight cases were above 4 ng/ml total PSA (tPSA) levels and four cases were within normal ranges, while free PSA/tPSA levels decreased to lower than 16% in all patients. Everefore and after TURBt."

Portal vein tumor thrombus (PVTT) remains a poor prognostic factor occurring in about 10%-40% of patients with hepatocellular carcinoma (HCC) for the optimal treatment is controversial. Anlotinib is an novel small molecule inhibitor that has a broad spectrum of inhibitory activities on tumor angiogenesis and growth. However, so far, no studies have reported the use of anlotinib in the treatment of HCC patients with PVTT. Here, we evaluated the safety and efficacy of anlotinib, followed by transarterial chemoembolization (TACE) and radiofrequency ablation (RFA) for the treatment of patients with HCC and PVTT.

A total of 145 consecutive HCC patients who underwent TACE in combination with RFA were enrolled in the retrospective study. Twenty-eight patients were diagnosed with PVTT and received anlotinib as basic treatment. The adverse events (AEs) were graded according to the National Cancer Institute Common Terminology Criteria for AEs Version 4.0. Time to tumor progression (TTP) and overall survival (OS) were calculated using the Kaplan-Meier method.

The most common toxicities related to anlotinib were pharyngalgia (53.6%), fatigue (42.9%), and hand-foot skin reaction (39.3%). The median OS was 13 months (range 3-18 months) with 1-year OS rate of 64.3%. The median TTP was 7 months (range 1-12 months) with 6-month rate of 46.4%.

Anlotinib followed by TACE and RFA is a safe and effective initial treatment modality for HCC patients with PVTT. Anlotinib may be a promising therapeutic option for relieving and/or stabilizing HCC with PVTT.

Although surgical resection is the optimal therapeutic approach for PC, about 30%-40% of those patients are not candidates for surgical resection when diagnosed. Chemotherapy and radiotherapy also could not claim a desirable effect on PC. The application of interventional radiology approaches is limited by unavoidable damage to the surrounding vessels or organs. By the superiority of mechanism and technology, IRE could ablate the tumor by creating irreversible pores on the membrane of PC cells with other tissues like vessels and pancreatic ducts untouched. This consensus gathers the theoretical basis and clinical experience from multiple Chinese medical centers, to provide the application principles and experience from Chinese experts in the IRE field.Hemolytic anemia and right ventricular outflow tract obstruction following device closure of ruptured sinus of Valsalva have seldom been reported in isolated case reports, and exact incidence is not known. selleck chemicals A gentleman presented with severe delayed hemolytic anemia following the use of cocoon duct occluder for ruptured sinus of Valsalva. Right ventricular outflow tract obstruction of unclear etiology was also reported on transthoracic echocardiography, necessitating retrieval of the device and surgical closure of the defect. Intraoperative transesophageal echocardiography (TEE) showed right ventricular outflow obstruction by the cocoon device itself with a normal pulmonary valve. In this report, we emphasize that improper device selection for closure of ruptured sinus of Valsalva aneurysm, may lead to delayed leaks across the device, which can gradually progress causing hemolytic anemia and high gradient across the right ventricular outflow tract. Intraoperative TEE helped to delineate the cause of right ventricular outflow tract obstruction.
