Background: Definitive chemoradiation is the primary treatment for locally advanced head and neck carcinoma (LAHNSCC). Optimising outcome predictions requires validated biomarkers, since TNM8 and HPV could have limitations. Radiomics may enhance risk stratification.

Background: Circulating tumor DNA (ctDNA) analysis has emerged as a minimally invasive tool for detecting minimal residual disease (MRD) in colorectal cancer (CRC) patients. This enables dynamic risk stratification, earlier recurrence detection and optimized post-surgical treatment. Two primary methodologies have been developed for ctDNA-based MRD detection: tumor-informed strategies, which identify tumor-specific mutations through initial tissue sequencing to guide ctDNA monitoring, and tumor-agnostic approaches, which utilize predefined panels to detect common cancer-associated genomic or epigenomic alterations directly from plasma without prior tissue analysis.

Colorectal cancer (CRC) has a 5-year overall survival rate of over 60%. The decrease in the rate of metastatic disease is due to screening programs and the population's awareness of healthy lifestyle. Similarly, advancements in surgical methods and the use of adjuvant chemotherapy have contributed to a decrease in the recurrence of resected disease.

Article Synopsis
  • Understanding how pancreatic ductal adenocarcinoma (PDAC) progresses and developing targeted therapies is crucial, and this study involved 80 metastatic PDAC patients divided into discovery and validation groups to examine genetic variants.
  • Whole exome sequencing (WES) of tumor and plasma samples highlighted that actionable mutations were more prevalent in plasma, and associations with cellular organization pathways were found in patients with shorter survival.
  • Notably, KRAS mutations in plasma were linked to worse progression free survival, while significant reductions in KRAS variant allele frequency correlated with improved outcomes similar to KRAS-negative patients, emphasizing the relevance of immune response pathways in liver metastasis.
