To investigate the appropriate timing of adaptive radiotherapy (ART) for high-grade glioma.

Ten patients with high-grade gliomas were selected and underwent CT/MRI (CT

, CT

, CT

, and CT

) scans before RT and during 10-, 20- and 30-fraction RT, and the corresponding RT plans (plan
, plan
, plan
and plan
) were made. The dose of the initial plan (plan
) was projected to CT2 and CT3 using the image registration technique to obtain the projection plans (plan
and plan
) and by superimposing the doses to obtain the ART plans (plan
and plan
), respectively. The dosimetric differences in the target volume and organs at risk (OARs) were compared between the projection and adaptive plans. The tumor control probability (TCP) for the planning target volume (PTV) and normal tissue complication probability (NTCP) for the OARs were compared between the two adaptive plans.

Compared with the projection plan, the D
to the PTV of ART decreased, the conformity index (CI) to the PTV increased, and the D

to the brainstem, optic chiasm and pituitary, as well as the V

and V
to the normal brain decreased. The D
to the pituitary and optic chiasm as well as the V
, V
, V
and V
to the normal brain in plan
were lower than those in plan
, while the CI to the PTV was higher than that in plan
. The TCP of the PTV in plan
was higher than that in plan
.

ART can improve the precision of target volume irradiation and reduce the irradiation dose to the OARs in high-grade glioma. The time point after 10 fractions of RT is appropriate for ART.

The occurrence of hepatocellular carcinoma (HCC) with bile duct tumor thrombus (BDTT) is rare. The aim of the study was to evaluate the effectiveness and safety of transarterial chemoembolization (TACE) for patients with unresectable HCC with BDTT.

This retrospective study was conducted on newly diagnosed HCC and BDTT patients who were initially treated with TACE or conservative management (CM) from 2009 to 2018. Rhapontigenin supplier Survival outcomes of patients treated with TACE were compared with those of patients given CM. Multivariate analyses were performed to identify independent prognostic factors related to survival.

Out of 100 patients included in this study, 40 patients underwent TACE, while the remaining 60 received CM. The median survival time of the TACE group was 8.0 months longer than that of the CM group (13.0 versus 5.0 months,
< 0.001). The 6-, 12-, 18-, 24-month overall survival (OS) rates were 90.0%, 52.5%, 22.5%, and 12.5%, respectively, for the TACE group compared with 26.7%, 8.3%, 5.0%, and 3.3%, respectively, for the CM group. Multivariate analyses showed that treatment allocation (hazard ratio [HR], 0.421; 95% confidence interval [CI], 0.243-0.730;
= 0.002), Child-Pugh status (HR, 2.529; 95% CI, 1.300-4.920;
= 0.006) and total bilirubin level (HR, 1.007; 95% CI, 1.004-1.009;
< 0.001) on first admission were independent predictors of OS. There was no procedure-related mortality within one month after TACE treatment.

TACE is a safe and effective treatment method that may improve the OS of patients with unresectable HCC with BDTT.

Accumulating evidence has indicated that dysregulated microRNAs (miRNAs) are involved in cancer progression. In this study, we evaluated the clinicopathologic significance of miR-183-3p and miR-182-5p, and the role of miR-183-3p in non-small-cell lung cancer (NSCLC) progression.

Seventy-six NSCLC patients from Beijing Chest Hospital were included. The expression of miR-183-3p and miR-182-5p was evaluated by real-time quantitative polymerase chain reaction (RT-qPCR). Then, cell growth curve assays and colony formation assays were performed. Bioinformatics analysis of TCGA database was performed to explore the clinicopathological significance and prognostic value.

miR-183-3p and miR-182-5p were significantly increased in NSCLC tumor tissues (both P < 0.0001) and were positively correlated (r = 0.8519, P < 0.0001). miR-183-3p (P = 0.0444) and miR-182-5p (P = 0.0132) were correlated with tumor size. In addition, miR-183-3p (P = 0.0135) and miR-182-5p (P = 0.0009) were upregulated in normal lung tissues from smokers. In vitro, miR-183-3p was correlated with cell proliferation. In addition, bioinformatics analysis indicated that miR-183-3p was correlated with poor prognosis (P = 0.0466) and tumor size (P = 0.0017). In addition, miR-183-3p was higher in lung squamous carcinoma (LUSC) tissue (P < 0.0001) than in lung adenocarcinoma (LUAD) tissue, and miR-183-3p was higher in the tumor tissue of smokers (P = 0.0053) than in that of nonsmokers.

Upregulation of miR-183-3p and miR-182-5p may play an oncogenic role in NSCLC. miR-183-3p could be used as a potential prognostic biomarker and therapeutic target to manage lung cancer.

Transcranial direct current stimulation (tDCS) may have therapeutic potential in the management of migraine. However, studies to date have yielded conflicting results. We reviewed studies using repeated tDCS for longer than 4 weeks in migraine treatment, and performed meta-analysis on the efficacy of tDCS in migraine.

In this meta-analysis, we included the common outcome measurements reported across randomized controlled trials (RCTs). Subgroup analysis was performed at different post-treatment endpoints, and with different stimulation intensities and polarities.

Five RCTs were included in the quantitative meta-analysis with a total of 104 migraine patients. We found a significant reduction of migraine pain intensity (MD -1.44; CI [-2.13, -0.76]) in active vs sham tDCS treated patients. Within active treatment groups, pain intensity and duration were significantly improved from baseline after tDCS treatment (intensity MD -1.86; CI [-3.30, -0.43]; duration MD -4.42; CI [-8.11, -0.74]) and during a follow-up period (intensity MD -1.
