Published: December 2024

This review paper explores the realm of non-invasive methods for early cancer detection. Early identification is crucial for effective therapeutic intervention, and non-invasive techniques have emerged as promising tools to enhance diagnostic accuracy and improve patient outcomes. The paper thoroughly examines the advantages, limitations, and prospects of various non-invasive approaches, including blood tests, non-blood-based tests, and diverse imaging modalities. It discusses the biomarkers found in blood for early-stage cancer detection, specifying the types of cancer associated with each biomarker. The non-blood-based tests focus on components in saliva, urine, and breath for cancer detection, alongside current studies and future perspectives on various cancers. Optical imaging methods covered in this review include fluorescence imaging in the near-infrared (NIR) region, bioluminescence imaging, and Raman spectroscopy for early-stage cancer detection. The review also highlights the pros and cons of ultrasound imaging in early-stage cancer detection. Additionally, the clinical implications of using AI for cancer detection, both present and future, are explored. This paper provides valuable insights for researchers and clinicians working in the field of non-invasive early-stage cancer detection.

Background: In triple-negative breast cancer (TNBC) patients receiving adjuvant capecitabine, the impact of HER2 expression on survival outcomes is unclear.

Methods:  Between June 2017 and December 2023, 112 patients with TNBC who received adjuvant capecitabine due to residual masses after neoadjuvant chemotherapy (NACT) in three hospitals were identified. HER2 is analyzed through immunohistochemistry (IHC) and/or in situ hybridization in the core biopsy and/or post-surgical histopathologies.

Purpose: Chronic pain is prevalent among breast cancer survivors. Bio-psychosocial factors interplay in its exacerbation and maintenance. Therefore, prevention and treatment require an interdisciplinary response and the integration of various approaches.

Introduction: The introduction of multiparametric prostate magnetic resonance imaging (mpMRI) has revolutionized prostate cancer (PCa) diagnosis, enhancing the localization of clinically significant prostate cancer (csPCa) and guiding targeted biopsies. However, significant disparities in the execution, interpretation, and reporting of prostate MRI examinations across centers necessitate greater standardization and accuracy. This study compares the diagnostic efficacy of mpMRI from academic and nonacademic centers in detecting csPCa and identifies factors associated with csPCa detection.

Background: The gene C9orf72 harbors a non-coding hexanucleotide repeat expansion known to cause amyotrophic lateral sclerosis and frontotemporal dementia. While previous studies have estimated the length of this repeat expansion in multiple tissues, technological limitations have impeded researchers from exploring additional features, such as methylation levels.

Methods: We aimed to characterize C9orf72 repeat expansions using a targeted, amplification-free long-read sequencing method.
