The correlation between LAG-3 expression and the efficacy of chemoimmunotherapy in advanced biliary tract cancer.

In our previous phase II T1219 trial for advanced biliary tract cancer (ABTC), the combination of nivolumab with modified gemcitabine and S-1 exhibited promising efficacy, while the programmed-death-ligand-1 (PD-L1) expression did not predict chemoimmunotherapy efficacy. Lymphocyte-activation-gene-3 (LAG-3), a negative immune checkpoint, is frequently co-expressed with PD-L1. This study assessed the predictive value of LAG-3 expression in ABTC patients who received chemoimmunotherapy.

Hepatic Events During Immune Checkpoint Inhibitor Treatment Between Liver and Non-Liver Malignancies in Hepatitis B Endemic Areas.

Background: Notable advances have been made in immune checkpoint inhibitors (ICIs) for cancer treatment. However, the adverse effects of ICIs, especially hepatotoxicity, remain a challenging problem. Whether patients in hepatitis B virus (HBV)-endemic areas are prone to developing hepatic adverse events during ICI treatment warrants further exploration.

Efficacy and safety of durvalumab rechallenge in advanced hepatocellular carcinoma patients refractory to prior anti-PD-1 therapy.

Background/purpose: Recently, anti-programmed cell death protein-1 (anti-PD-1) and anti-PD-L1 therapies were approved for hepatocellular carcinoma (HCC). However, the effectiveness of rechallenging with one immune checkpoint inhibitor (ICI) after failure of another remains unclear. This study explores the efficacy and safety of anti-PD-L1 rechallenge in patients who failed anti-PD-1 therapy.

Real-world effectiveness and prognostic factors of durvalumab plus chemotherapy in a multicentric cohort with advanced biliary tract cancer.

Background: Biliary tract cancer (BTC) is an aggressive biliary tract cancer, arising from the bile ducts and gallbladder, with a poor prognosis. The TOPAZ-1 trial of durvalumab plus first-line chemotherapy (gemcitabine plus cisplatin) showed improved survival vs chemotherapy alone. This real-world study aimed to confirm the effectiveness of this regimen.

Delivery-First Strategy Followed by Endovascular Repair to Treat Pregnant Woman With Acute Complicated Type B Aortic Dissection.

Objective: Aortic dissection, a rare but serious condition, requires timely diagnosis and treatment.

Case Report: A case report involving a 33-year-old female with Stanford type B aortic dissection at 32 + 3 weeks gestational age highlights the importance of being alert to the symptoms and signs of this condition, particularly in patients with hypertension or a history of connective tissue disorders. The case report suggests a delivery first strategy followed by TEVAR procedure as the preferred approach for managing aortic dissection in pregnancy.

RAB31 drives extracellular vesicle fusion and cancer-associated fibroblast formation leading to oxaliplatin resistance in colorectal cancer.

Epithelial-mesenchymal transition (EMT) is associated with tumorigenesis and drug resistance. The Rab superfamily of small G-proteins plays a role in regulating cell cytoskeleton and vesicle transport. However, it is not yet clear how the Rab family contributes to cancer progression by participating in EMT.

Durvalumab or placebo plus gemcitabine and cisplatin in participants with advanced biliary tract cancer (TOPAZ-1): updated overall survival from a randomised phase 3 study.

Background: In the preplanned interim analysis of the TOPAZ-1 study, durvalumab plus gemcitabine-cisplatin significantly improved overall survival versus placebo plus gemcitabine-cisplatin in participants with advanced biliary tract cancer. We aimed to report updated overall survival and safety data from TOPAZ-1 with additional follow-up and data maturity beyond the interim analysis.

Methods: TOPAZ-1 was a phase 3, randomised, double-masked, placebo-controlled, global study done at 105 sites in 17 countries.

Cost-effectiveness of ivosidenib versus chemotherapy for previously treated IDH1-mutant advanced intrahepatic cholangiocarcinoma in Taiwan.

Background: International guidelines recommend ivosidenib followed by modified FOLFOX (mFOLFOX) for advanced intrahepatic cholangiocarcinoma (ICC) with isocitrate dehydrogenase 1 (IDH1) mutations. Taiwan National Health Insurance covers only fluorouracil/leucovorin (5-FU/LV) chemotherapy for this ICC group, and there has been no prior economic evaluation of ivosidenib. Therefore, we aimed to assess ivosidenib's cost-effectiveness in previously treated, advanced ICC-presenting IDH1 mutations compared with mFOLFOX or 5-FU/LV.

Does the guideline-based physical activity level for cardiovascular health also benefit periodontal health?

Abstract Background/purpose: It is unclear about whether the guideline-based physical activity (PA) level for cardiovascular health also benefits periodontal health. Therefore, this study aimed to clarify the association between guideline-based PA levels and periodontitis in young adults.

Materials And Methods: This was a cross-sectional study which included 334 military participants, aged 18-44 years in Taiwan.

Obesity Phenotypes and Dental Calculus in Young Adults: CHIEF Oral Health Study.

Aim: The study aimed to examine the association of obesity phenotypes with dental calculus.

Background: Obesity has been recognized as a risk factor for kidney and gallbladder stones formation and periodontitis.

Objective: We have investigated the association between obesity, metabolic risk factors, and dental calculus, which is a sequela following periodontitis.

Comparison of therapeutic outcomes in esophageal squamous cell carcinoma following neoadjuvant chemoradiotherapy: A prospective observational cohort study.

Background: Patients with locally advanced esophageal squamous cell carcinoma (ESCC) following neoadjuvant chemoradiotherapy (nCRT) may not always receive resection despite the possible achievement of a pathologic complete response (pCR) being associated with superior survival benefit. We aimed to compare outcomes among ESCC patients with or without pCR and those refusing surgery.

Methods: In total, 111 medically operable, non-cervical ESCC patients after the same protocol of nCRT (platinum/5-fluorouracil plus radiation 50Gy) were prospectively enrolled between 2011 and 2021.

Immunoprofile of adenosquamous carcinoma in gastric cancer.

Background: Gastric adenosquamous carcinoma (GASC) is a rare subtype of gastric cancer. Research on GASC treatment is limited, and its outcome is usually poor. We investigated the clinical features, immunoprofile of GASC, and determined the optimal treatment modality for these patients.

Comparison of the mutation patterns between tumor tissue and cell-free DNA in stage IV gastric cancer.

Compared to stage I-III gastric cancer (GC), the level of cell-free DNA (cfDNA) was significantly higher in stage IV GC. The mutation patterns of different metastatic patterns between cfDNA and tumor DNA in stage IV GC have not yet been reported. We used next-generation sequencing (NGS) to analyze cfDNA and tumor DNA in 56 stage IV GC patients.

A G-quadruplex stabilizer, CX-5461 combined with two immune checkpoint inhibitors enhances in vivo therapeutic efficacy by increasing PD-L1 expression in colorectal cancer.

Purpose: Immune checkpoint inhibitors (ICIs) alone or in combination with chemotherapy can improve the limited efficacy of colorectal cancer (CRC) immunotherapy. CX-5461 causes substantial DNA damage and genomic instability and can increase ICIs' therapeutic efficacies through tumor microenvironment alteration.

Results: We analyzed whether CX-5461 enhances ICIs' effects in CRC and discovered that CX-5461 causes severe DNA damage, including cytosolic dsDNA appearance, in various human and mouse CRC cells.
