Advanced breast cancer holds a poor prognosis for chemotherapy and endocrine therapy resistance. Autophagy is one of the main causes of tumor drug-therapy failure, and increasing evidence shows that EMT also is responsible for that. Metastasis-associated protein1 (MTA1) is up regulated in lots of tumors, which leads to tumor progression and drug resistance. However, the role of MTA1 in chemotherapeutic resistance in luminal-b breast cancer is still unclear. In this paper, our research shows that higher expression of MTA1 accompanies with worse prognosis in luminal-b breast cancer. Knockdown of MTA1 enhances the sensitivity of MCF-7 to gemcitabine and weakens the metastasis ability of MCF-7 in vitro and in vivo. Further, we find that knockdown of MTA1 strengthens the gemcitabine-mediated tumor growth inhibition effect in vivo, through reversion of the EMT process and inhibition of the autophagy process. Furthermore, our research builds the siMTA1-loaded exosomes, which increases the gemcitabine-mediated tumor growth inhibition effect in vivo.
The purpose of the study is to summarize the clinical characteristics and identify the prognosis of clear cell adenocarcinoma of the uterine cervix (CCAUC) in patients without a history of diethylstilbestrol (DES) exposure.

Forty-two patients with CCAUC, treated initially at Sun Yat-sen University Cancer Center between 1985 and 2017, were studied.

Of all the CCAUC patients, the median age was 47years old, and the median tumor size was 3cm. Thirty-four early stage patients (IB=28, IIA=6) underwent radical surgery. Eight advanced stage patients (IIB=8) received concurrent chemoradiotherapy (n=4) or radical surgery (n=4). Aristolochic acid A Survival analysis showed that patients with early stage (IB-IIA) had a significantly better 5-year progression-free survival (PFS) and overall survival (OS) than those with advanced stage (IIB) (
<0.05). The patients with negative pelvic lymph node (PLN) had a significantly better 5-year PFS and OS than those with positive PLN (
<0.05). Radiotherapy (RT) did not affect PFS or OS in early stage patients with intermediate risk factors (
>0.05). Adjuvant chemotherapy (CT) did not affect PFS or OS in early stage patients without risk factors (
>0.05).

The FIGO stage and pelvic node status were important prognostic factors for both PFS and OS. For treatment modality, we recommended that radical surgery alone was used in early stage patients without high risk factors. Ovarian preservation in early stage patients involved some risk.

In this study, we report the downregulation of LINC01089 in non-small cell lung cancer (NSCLC) samples, relative to adjacent non-tumor tissues, and demonstrate its role in the inhibition of proliferation, migration, and epithelial-mesenchymal transition (EMT) of NSCLC cells. Mechanistic analysis indicates that LINC01089 acts as a sponge for miR-27a, regulating its expression in NSCLC. Interestingly, LINC01089 mediated the upregulation of SFRP1 expression by inhibiting the Wnt/β-catenin-EMT pathway and inhibiting the epithelial-mesenchymal transition of NSCLC via sponging miR-27a. Overall, our findings highlight LINC01089's tumorigenic role and regulatory mechanism in NSCLC, thereby suggesting its potential as a therapeutic target for managing NSCLC.
To develop a radiomics signature for predicting surgical portal vein-superior mesenteric vein (PV-SMV) in patients with pancreatic ductal adenocarcinoma (PDAC) and measure the effect of providing the predictions of radiomics signature to radiologists with different diagnostic experiences during imaging interpretation.

Between February 2008 and June 2020, 146 patients with PDAC in pancreatic head or uncinate process from two institutions were retrospectively included and randomly split into a training (n = 88) and a validation (n =58) cohort. Intraoperative vascular exploration findings were used to identify surgical PV-SMV invasion. Radiomics features were extracted from the portal venous phase CT images. Radiomics signature was built with a linear elastic-net regression model. Area under receiver operating characteristic curve (AUC) of the radiomics signature was calculated. A senior and a junior radiologist independently review CT scans and made the diagnosis for PV-SMV invasion both with and without rawas significant (63.2 vs 89.5%,
-value = 0.025) instead of the senior radiologist (73.7 vs 89.5%,
-value = 0.08). Both radiologists' accuracy had no significant increase when provided radiomics signature assistance (both
-values > 0.05).

The radiomics signature can predict surgical PV-SMV invasion in patients with PDAC and may have incremental value to the diagnostic performance of radiologists during imaging interpretation.

To investigate the effect of local treatment strategy on survival outcome in
stage IV breast cancer patients who received chemotherapy.

We identified stage IV breast cancers that presented with synchronous metastasis from the Surveillance, Epidemiology, and End Results database. Binomial logistic regression, Kaplan-Meier survival curves, propensity score matching (PSM), and multivariate Cox regression model were used for statistical analyses.

We identified 5,374 patients in total, including 2,319 (43.2%), 2,137 (39.8%), and 918 (17.1%) patients who received surgery alone, surgery+radiotherapy, and radiotherapy alone, respectively. The probability of patients receiving surgery alone decreased over time, and the probability of patients receiving radiotherapy alone increased over time. However, no significant difference was observed in the probability of patients receiving postoperative radiotherapy (P = 0.291). The 3-year breast cancer-specific survival (BCSS) in patients treated with surgery alone, ra postoperative radiotherapy further improves outcome after primary tumor removal. Local treatment can only be an option in highly selected patients with de novo stage IV disease in the treatment guidelines. More prospective studies are needed to investigate the role of local management for this patient subset.Hepatoblastoma (HB) is the most common malignant liver neoplasm in children. Despite progress in HB therapy, outcomes for patients with metastatic disease remain poor. Dysregulation of miRNA expression is one of the potential epigenetic mechanisms associated with pathogenesis of HB. However, miRNA profiles related to the different stages of HB tissues and cells, in particular of lung metastatic tumor cells, are unknown. In the present study, using array-based miRNA expression and DNA methylation analysis on formalin-fixed paraffin-embedded tissues, we aimed to identify miRNA changes that can discriminate between lung metastatic tumors, primary tumors (fetal and embryonal subtypes), and nontumorous surrounding livers. Our analysis demonstrated that a large cluster of microRNAs and snoRNAs located within the 14q32.2 DLK1-DIO3 region showed a strikingly upregulated expression pattern in HB tumors, especially metastatic tumors, compared to normal liver tissues. This revealed dysregulation of miRNAs similar to that seen in a malignant stem-like subtype of hepatocellular carcinoma associated with poor prognosis. These findings in HB mirror similar findings made in multiple other cancer types. With further analysis this may in future allow stratification of different stages and types of HB tumors based on their miRNA profiles, which could lead to new approaches to diagnosis and treatment in progressive HB patients.The use of biological therapy is now common practice in the treatment of immune-mediated inflammatory diseases (IMID). Currently, there are no guidelines related to the management of cytomegalovirus (CMV) infections or reactivation during therapy with biological agents. Furthermore, there is a lack of guidance on the management of asymptomatic patients with persistent positive immunoglobulin (Ig)M anti-CMV after an extended period and who have to undergo therapy with biological agents. We report the case of a patient in this situation for whom treatment with biological drugs for psoriasis was indicated. A good clinical response was obtained with secukinumab and maintained during 6 months of follow-up. No infectious disease or reactivation of CMV infection occurred. We suggest some possible guidelines for the management of such cases.
Aortic dissection is a cardiovascular emergency with an overall in-hospital mortality rate of 27.4%, and with every hour without intervention, the mortality rate increases by 1%-2% in the first 48 hours. Thoracic aortic dissection typically presents with tearing chest, back, or abdominal pain. Coronavirus disease 2019 (COVID-19) is a viral disease caused by severe acute respiratory syndrome-coronavirus 2 (SARS-Cov2), which has been declared a pandemic by the World Health Organization (WHO) and usually manifests with respiratory symptoms, including cough, shortness of breath, flu-like symptoms, and fever. This case report highlights an important impact of the COVID-19 pandemic on the identification and management of aortic dissection in the emergency department.

A 35-year-old Bahraini male, a suspected case of Marfan syndrome, presented with complaints of shortness of breath and worsening productive cough after returning from the United States (U.S). He denied any chest, back, or abdominal pain, dizziness,VID-19 pandemic has been a major stressor for the healthcare system worldwide, inflicting serious threats. Aortic dissection is one of the major life-threatening diseases that needs to be identified early on in the emergency department; however, in this case delayed diagnosis raised significant concerns due to underlying evolving triaging system for COVID-19 and atypical and overlapping clinical presentation. Further research is needed to look for COVID-19-associated factors, affecting the standard of care in the emergency department. Improving handover can directly impact patient care; therefore, it should be optimized.The modified Valsalva maneuver (MVM) has never before been performed in the prehospital setting by the Hamad Medical Corporation Ambulance Service (HMCAS) clinicians in the State of Qatar. Currently, their clinical practice guidelines (CPG) prescribe the vagal maneuver (VM) using a 10 cc syringe as first-line therapy for patients presenting with symptomatic paroxysmal supraventricular tachycardia (pSVT). The effectiveness of the MVM in terminating pSVT compared to the traditional VM is well documented, although prehospital studies in this area are lacking. In this case, a generally healthy, 47-year-old male migrant worker presented with new-onset symptomatic pSVT, which was successfully terminated by a MVM after initial failed attempts of the traditional VM. The MVM is a postural technique performed by initially placing the patient in a semirecumbent position. The patient is then encouraged to blow into a manometer to achieve a 40 mmHg intrathoracic pressure for 15 seconds. Once the 40 mmHg intrathoracic pressure is achieved, the patient is repositioned supine, and their legs are raised passively to 45 degrees for 15 seconds.
