AI Article Synopsis

  • The study assessed the effectiveness and safety of flumatinib in five patients newly diagnosed with chronic myeloid leukemia in the chronic phase (CML-CP), administered at a dosage of 600 mg/day.
  • All five patients achieved optimal molecular response within three months, with two reaching major molecular response (MMR) and one maintaining undetectable molecular residual disease for over a year.
  • While some patients experienced mild side effects, including grade 3 hematological toxicity and transient diarrhea, there were no serious cardiovascular issues related to the treatment, indicating that flumatinib is both effective and generally safe for this condition.

Article Abstract

The present study aimed to investigate the efficacy and safety of flumatinib in patients newly diagnosed with chronic myeloid leukemia in the chronic phase (CML-CP). A retrospective study was conducted using five patients newly diagnosed with CML-CP who received flumatinib (600 mg/day). Results of the present study demonstrated that all five patients with CML-CP that were treated with flumatinib achieved the optimal molecular response within three months. In addition, two patients experienced major molecular response (MMR), and one patient acquired undetectable molecular residual disease, which was maintained for more than one year. Moreover, one patient exhibited grade 3 hematological toxicity, two patients exhibited transient diarrhea, one patient exhibited vomiting and one patient exhibited a rash with pruritus. No second-generation tyrosine kinase inhibitor-specific adverse cardiovascular events occurred in any patients. In conclusion, flumatinib exhibits high efficacy and high early molecular response rate in patients newly diagnosed with CML-CP. The majority of patients obtained MMR within three months, and the adverse reactions experienced were mild and tolerable.

Cuproptosis, a newly identified form of cell death, has drawn increasing attention for its association with various cancers, though its specific role in colorectal cancer (CRC) remains unclear. In this study, transcriptomic and clinical data from CRC patients available in the TCGA database were analyzed to investigate the impact of cuproptosis. Differentially expressed genes linked to cuproptosis were identified using Weighted Gene Co-Expression Network Analysis (WGCNA).

Objectives: This study aimed to explore differences in demographics, tumour characteristics and outcomes in oral squamous cell carcinoma (OSCC) patients with a history of non-smoking, non-drinking (NSND) versus smoking and/or drinking (SD).

Materials And Methods: Newly diagnosed OSCC patients undergoing curative surgical treatment were prospectively included in OncoLifeS, a data biobank. Cox regression analysis was performed yielding hazard ratios (HRs) and 95% confidence intervals (95%CIs).

Background: Pharmacological treatment is a cornerstone of chronic obstructive pulmonary disease (COPD) management, with general practitioners providing the most care. However, the lack of data on prescribing trends in initial pharmacotherapy in primary care hinders the understanding of how scientific and technical developments impact patient care and may also perpetuate suboptimal practices. Hence, this study aims to analyze trends in the initial pharmacological treatment of newly diagnosed COPD patients in Dutch primary care from 2010 to 2021.
