Summary: This study investigated the association of proximal serrated polyp detection rate (PSDR) and adenoma detection rate (ADR) with post-colonoscopy colorectal cancer (PCCRC) death. The results showed that both ADR and PSDR were significantly associated with PCCRC death. Therefore, striving for a high PSDR in addition to a high ADR may reduce the risk of PCCRC mortality in patients undergoing screening colonoscopy.

Summary: Colorectal cancer is characterized by mutations and abnormal DNA methylation in tumor suppressor and proto-oncogenes. This study identified nine genes with high methylation levels in tumor tissues compared to normal tissues. Molecular sub-classification based on mutations and epigenetic modifications may help identify epigenetic biomarkers for personalized treatment strategies to improve patient outcomes.

Summary: The study demonstrates that the NuProbe VarTrace BRAF sequencing technology can detect BRAF V600 mutations down to 0.20% VAF from FFPE lymph node tissue samples, with high concordance among various methods for samples with VAF>=1% BRAF mutations, but with possible false negatives in IHC. The BDA Sanger method is effective for rapid detection and quantitation of multiple low VAF BRAF mutations.

Summary: The choice of cancer drugs for advanced melanoma treatment depends on gene alterations in the patient's tumor. Blood samples can reliably determine gene alterations, offering a convenient and fast option for testing. This study suggests that using blood samples for testing could be a less invasive and quick alternative to identify BRAF mutation status in melanoma patients.

Summary: This study found that BRAF mutations do not significantly affect the predictive ability of miR-125b, miR-200c, and miR-205. These three miRNAs can independently predict the clinical outcomes of patients with primary melanoma, regardless of BRAF mutational status.

Summary: Liquid biopsy and cell-free DNA have great potential in cancer diagnostics, with a custom ddPCR assay designed for quantification of cfDNA in serum. The study validated the assay on CRC patients, hemorrhoid patients, and healthy controls, comparing mutation status in primary tumors and cfDNA isolated from serum. The findings suggest caution in interpreting decisions based solely on cfDNA levels in patient serum, and explore the potential of ddPCR somatic mutations detection from liquid biopsy as a supplement to tissue biopsy in personalized CRC patient management.

Summary: Mutations in BRAF exon 15 lead to constitutively active BRAF proteins, which are associated with the development of several human cancer types. The SensiScreen((R)) FFPE BRAF qPCR Assay is a novel real-time PCR-based method that displays high sensitivity, specificity, and ease of use. It allows for the identification and characterization of BRAF mutations, providing a more specific and cost-effective approach for cancer patients.

Summary: Cutaneous melanoma, the most aggressive form of skin cancer, is driven by the accumulation of genetic alterations, including BRAF mutations. Targeted therapies against these mutations have revolutionized the treatment of melanoma patients, but resistance remains a challenge. This review summarizes recent findings on the impact of BRAF mutations on melanoma development, with a focus on inflammation, as well as the mechanisms of resistance to BRAF inhibitors and circulating tumor biomarkers.

Summary: This is a population-based cohort study conducted in the South Region of Portugal to estimate the incidence of cutaneous malignant melanoma, characterize diagnosed individuals, describe treatment, and estimate survival outcomes. The study found a melanoma incidence rate of 13.36/100,000 inhabitants and a 3-year overall survival rate of 80.54%. The adjusted hazard ratio showed a two-fold increased risk of recurrence/death in the presence of ulcerated tumors.

Summary: This study analyzed serial blood samples from metastatic colorectal cancer patients and sequenced ctDNA to evaluate its clinical utility. The results showed that ctDNA clearance after chemotherapy was associated with longer progression-free survival, independent of radiological response. Longitudinal ctDNA monitoring detected ctDNA progression earlier than radiological progressive disease in a significant percentage of patients.

Summary: The MM500 meta-study aims to establish a knowledge basis of the tumor proteome as a complement to genome and transcriptome studies. By analyzing 505 well-annotated melanoma tumor samples, the study defined the melanoma proteome landscape, including thousands of proteins and mutated proteoforms. The study found a high degree of correlation between the melanoma transcriptome and proteome, increasing understanding of melanoma disease.

Summary: This study is the first to demonstrate genetic alterations specific to Chinese patients with RMM. The research confirmed that genetic alterations in RMM differ from cutaneous melanoma (CM). The study suggests that BRAF and NRG1 are associated with poor prognosis in RMM and may be potential therapeutic targets for RMM treatment.

Summary: Testing for the BRAF mutation is essential for managing patients with locally advanced or metastatic melanoma. Using molecular analysis based on DNA sequencing is the gold standard method for screening mutations. Comparison between the Idylla BRAF Mutation Test and anti-BRAF V600E immunohistochemistry showed a 91% agreement rate for the detection of BRAF V600E mutation.

Summary: In postmenopausal ER-positive/HER-2-negative LABC patients treated with neoadjuvant endocrine therapy, there is a correlation between MRI morphological response patterns and histopathological tumor regression grading. The type II MRI pattern was most common after 2 and 4 months of therapy, with histopathological regression grade 3 being the most common after 4 months. The correlation between MRI patterns and histopathology was moderate, with type IV showing the strongest correlation.

Summary: In this study, phenotypic markers were combined with targeted DNA sequencing to discover novel biomarkers for guiding surgical management in high-grade serous ovarian carcinoma (HGSOC) patients. The study highlights the potential of a preoperative risk stratification model combining phenotypic traits and single-gene mutational status in predicting surgical outcomes.
