Purpose: Next-generation sequencing (NGS) has revolutionized cancer treatment by enabling comprehensive cancer genomic profiling (CGP) to guide genotype-directed therapies. While several prospective trials have demonstrated varying outcomes with CGP in patients with advanced solid tumors, its clinical utility in colorectal cancer (CRC) remains to be evaluated.
Methods: We conducted a prospective observational study of CGP in our hospital between September 2019 and March 2024.

T-cell receptors (TCRs) recognize antigens derived from fragments of somatically expressed proteins that are degraded by the proteasome and presented by specific human leukocyte antigen (HLA) molecules. Recent therapeutic advances using the TCR as a tumor-targeting moiety have focused attention on loss of heterozygosity (LOH) as a potential resistance mechanism. Allele-specific LOH, rather than allele-agnostic, is particularly pertinent, but rarely evaluated.

Our research aims to ascertain the value of precursor and outgrowth lepidic in aiding the confirmation of multiple lung adenocarcinomas as separate primary lung cancers (SPLC). A total of 151 patients with metachronous multiple invasive adenocarcinomas were included in this study. Driver mutation tests(at least five genes: EGFR, ALK, KRAS, BRAF, and ROS1) were conducted on 302 tumors collected from 151 patients.

Despite recent advances in neoadjuvant strategies for locally advanced rectal cancer (LARC), optimal chemotherapy regimens and the role of genetic biomarkers in guiding treatment remain unclear. Moreover, predictive markers are urgently needed for radiation-sparing strategies. Therefore, we aimed to assess the predictive and prognostic value of TP53, KRAS, and APC mutations in patients with LARC undergoing neoadjuvant chemotherapy (NACT) by retrospectively analyzing 43 patients with LARC who underwent NACT without radiation.

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies, with limited treatment options and poor prognosis. Recent advances in cancer genomic analysis enable the identification of actionable gene alterations, opening new opportunities for personalized therapy. Among these, homologous recombination DNA repair (HRR) gene alterations are associated with distinct biological behavior, favorable prognosis, and increased sensitivity to platinum-based chemotherapy.
