The primary challenge in reporting cancer cases lies in the labor-intensive and time-consuming process of manually reviewing numerous reports. Current methods predominantly rely on rule-based approaches or custom-supervised learning models, which predict diagnostic codes based on a single pathology report per patient. Although these methods show promising evaluation results, their biased outcomes in controlled settings may hinder adaption to real-world reporting workflows.

Background: Low-dose computed tomography (LDCT) has been widely adopted for lung cancer screening due to its proven ability to reduce lung cancer mortality, especially among high-risk populations.

Methods: This retrospective study aims to evaluate the impact of LDCT screening on non-small cell lung cancer (NSCLC) staging at Kaohsiung Medical University Hospital (KMUH) from 2011 to 2020, following the introduction of LDCT in 2013. The study examines the correlation between LDCT screening volume and changes in the distribution of NSCLC stages, particularly early-stage (stages 0 and I) and late-stage (stage IV) diagnoses.

Article Synopsis
  • Idiopathic pulmonary fibrosis (IPF) is a severe lung disease with limited treatments, and pirfenidone has been approved for its treatment in Taiwan since 2016.
  • A study was conducted on 50 IPF patients in Taiwan to assess the real-world safety and effectiveness of pirfenidone, revealing that most patients showed no significant changes in lung function or walking distance after treatment, although pirfenidone did help stabilize cough symptoms.
  • The study found that while 62% of patients experienced side effects, with decreased appetite being most common, overall, pirfenidone was considered an effective and safe option for IPF treatment in this population.

Objectives: The weekly rifapentine plus isoniazid for 3 months (3HP) improves completion rate of latent tuberculosis infection treatment, but flu-like symptoms are common. The novel 1HP regimen, involving daily rifapentine plus isoniazid for 28 days, has demonstrated low toxicity in HIV-infected populations. We aimed to investigate whether 1HP has a lower incidence rate of systemic drug reaction (SDR) compared with 3HP during treatment in non-HIV populations.

Data curation for a hospital-based cancer registry heavily relies on the labor-intensive manual abstraction process by cancer registrars to identify cancer-related information from free-text electronic health records. To streamline this process, a natural language processing system incorporating a hybrid of deep learning-based and rule-based approaches for identifying lung cancer registry-related concepts, along with a symbolic expert system that generates registry coding based on weighted rules, was developed. The system is integrated with the hospital information system at a medical center to provide cancer registrars with a patient journey visualization platform.

Article Synopsis
  • Combining EGFR tyrosine kinase inhibitors (TKIs) with anti-VEGF agents, like bevacizumab or ramucirumab, is a treatment option for advanced lung adenocarcinoma with specific EGFR mutations.
  • A study involving 47 patients showed that the effectiveness, in terms of response rates and survival, was similar for both bevacizumab and ramucirumab when combined with EGFR-TKIs.
  • However, patients on ramucirumab experienced significantly higher rates of high-grade hypertension, and additional factors like poor performance status and brain metastasis were linked to worse progression-free survival.

Article Synopsis
  • In Taiwan, a study called TALENT is examining the effectiveness of low-dose CT (LDCT) screening for lung cancer in never-smokers who have other risk factors, as nearly 60% of such patients are diagnosed at advanced stages.
  • The study involved 17 medical centers and included individuals aged 55-75 who met specific eligibility criteria, like having never smoked or having a very limited smoking history, and certain risk factors for lung cancer.
  • Preliminary results from a 1-year follow-up after the initial LDCT screenings were analyzed, focusing on the detection rates of lung cancer and using various statistical methods to evaluate the outcomes.

Gastric cancer (GC) organoids are frequently used to examine cell proliferation and death as well as cancer development. Invasion/migration assay, xenotransplantation, and reactive oxygen species (ROS) production were used to examine the effects of antioxidant drugs, including perillaldehyde (PEA), cinnamaldehyde (CA), and sulforaphane (SFN), on GC. PEA and CA repressed the proliferation of human GC organoids, whereas SFN enhanced it.

Article Synopsis
  • The Omicron variant of SARS-CoV-2, noticed first in October 2021, had many mutations and led to a significant COVID-19 outbreak in Taiwan between January and September 2022, primarily driven by the BA.2.3.7 subvariant.
  • This subvariant, detected in March 2022, showed increased severity and was correlated with higher risks for older patients and those with comorbidities during the outbreak.
  • Despite the outbreaks, Taiwan’s case fatality rate (CFR) dropped to 0.16% during this period, lower than the global average, thanks to improved public health measures, vaccination drives, and effective antiviral treatments.

Stomach cancer has a high mortality, which is partially caused by an absence of suitable biomarkers to allow detection of the initiation stages of cancer progression. Thus, identification of critical biomarkers associated with gastric cancer (GC) is required to advance its clinical diagnoses and treatment. Recent studies using tracing models for lineage analysis of GC stem cells indicate that the cell fate decision of the gastric stem cells might be an important issue for stem cell plasticity.
