Summary: In this study, a personalized and tumor-informed ctDNA assay was used to analyze plasma samples from 69 patients with advanced melanoma. The results showed that ctDNA levels were correlated with survival and disease progression in these patients, suggesting that it could be a reliable biomarker for predicting treatment response and disease recurrence.

Summary: This study of 200 Chinese patients with advanced gastric adenocarcinoma revealed that the majority carried genomic alterations, with common mutations in genes like TP53, LRP1B, MYC, ERBB2, and KRAS. Patients with high bTMB and bMSI-H had a higher percentage of del-alterations in the DDR pathway. Over 45% of cases had potentially actionable alterations, showing promise for ctDNA NGS in informing clinical decisions for advanced gastric adenocarcinoma.

Summary: Colorectal cancer is a major cause of cancer-related deaths globally. A significant portion of patients present with rectal cancer in the locally-advanced stage, requiring multi-modality therapy. Utilizing circulating tumor DNA for predicting response to neoadjuvant therapy shows promise in improving patient selection for non-surgical approaches.

Summary: Biomarkers such as F-18-FDG-PET/CT non-response and ctDNA detection can help identify patients with metastatic breast cancer who may not benefit from adding everolimus to endocrine treatment. Patients who show metabolic non-response or detect ctDNA after 14 days of treatment have a lower probability of benefiting from the treatment, as indicated by shorter progression-free survival. Validation from independent studies is necessary.

Summary: ctDNA, a fragmented genomic material, serves as a crucial biomarker in tumor diagnosis and monitoring. Its non-invasive nature makes it a preferred choice for patients with limited sample collection. Gastric cancer, a malignancy influenced by multiple factors, presents challenges for researchers focusing on genetic and epigenetic changes.

Summary: This study utilized a highly sensitive targeted next-generation sequencing approach to monitor tumor dynamics in synovial sarcoma patients. The detection of circulating tumor DNA (ctDNA) correlated with the presence of viable tumor tissue, allowing for non-invasive detection of tumor recurrence and monitoring of treatment response. The findings suggest that targeted NGS could be a valuable tool for the diagnosis and treatment of synovial sarcoma.

Summary: The study found a moderate but significant correlation between ctDNA variant allele frequency and imaging measures of tumor burden, with varying strengths based on tumor genotypes. Factors such as TP53 and EGFR mutations, visceral metastasis, and tumor burden were independent predictors of increased ctDNA shedding, suggesting that ctDNA levels are affected by both tumor burden and genotype.

Summary: HLA-I LOH prevalence varies across different cancer types, and is associated with genomic instability and higher tumor mutation burden levels. Enrichment of alterations in DNA damage response pathways and higher mutation rates of tumor suppressors are seen in HLA-I LOH cases. These findings may have implications for future tumor immunology research.

Summary: Brain metastases are common in NSCLC patients and immune checkpoint inhibitors (ICIs) have become a routine treatment for these patients. Various ICIs have been approved for the first-line treatment of metastatic NSCLC, but the use of PD-L1, tumor infiltrating lymphocytes, and tumor mutation burden as predictive biomarkers for ICIs in NSCLC patients with BM remains controversial with insufficient clinical data.

Summary: In this study, the response and survival of patients with primary malignant melanoma of the esophagus (PMME) and non-esophageal mucosal melanoma (NEMM) under anti-PD-1 monotherapy were analyzed. PMME showed a better response to anti-PD-1 treatment compared to NEMM, with higher objective response rate and disease control rate. Genomic and transcriptome analyses revealed molecular differences between PMME and NEMM, supporting the distinct molecular characteristics of PMME.

Summary: This study found that lung adenocarcinomas (LUAD) with EGFR-positive and ALK-positive had a suppressive tumor immune microenvironment (TIME) and were less responsive to immunotherapy. The TIME in patients with EGFR/ALK-positive LUAD brain metastases (BMs) was different from that in primary lung cancer. Evaluating the immune characteristics of LUAD BMs is important for clinical treatment.
