Next-generation sequencing (NGS) offers a promising approach for differentiating multiple primary lung cancers (MPLC) from intrapulmonary metastasis (IPM), though panel selection and clonal interpretation remain challenging. Whole-exome sequencing (WES) data from 80 lung cancer samples were utilized to simulate MPLC and IPM, with various sequenced panels constructed through gene subsampling. Two clonal interpretation approaches primarily applied in clinical practice, MoleA (based on shared mutation comparison) and MoleB (based on probability calculation), were subsequently evaluated.

Lymph node metastasis significantly affects the NSCLC patients' staging, treatment strategy, and prognosis. Studies have shown that IGF2BP3, an oncofetal protein and an m6A reader, overexpresses and correlates to lymph node metastasis and worse overall survival in histopathological studies including NSCLC, but its mechanism needs further study. This study explored IGF2BP3's function and mechanism in LUAD lymphatic metastasis using public databases, a human LUAD tissue microarray, human LUAD cells, and a lymphatic metastasis model in male BALB/c nude mice.

Malignant gliomas are heterogeneous tumors, mostly incurable, arising in the central nervous system (CNS) driven by genetic, epigenetic, and metabolic aberrations. Mutations in isocitrate dehydrogenase (IDH1/2) enzymes are predominantly found in low-grade gliomas and secondary high-grade gliomas, with IDH1 mutations being more prevalent. Mutant-IDH1/2 confers a gain-of-function activity that favors the conversion of a-ketoglutarate (α-KG) to the oncometabolite 2-hydroxyglutarate (2-HG), resulting in an aberrant hypermethylation phenotype.

Article Synopsis
  • The study analyzes how clinical risk stratification can be used to assess the advantages of long-term androgen deprivation therapy (ltADT) compared to short-term therapy (stADT) in high-risk localized prostate cancer patients.
  • Results indicate that patients with very-high risk features have greater improvements in survival outcomes when treated with ltADT, although the variation in treatment effects across different risk groups is not statistically significant.
  • The findings suggest the need for further clinical trials to refine risk stratification methods and better identify which high-risk localized prostate cancer patients could benefit more from longer therapy.

Lymphomas of T-follicular helper origin (T-follicular helper-cell lymphoma [TFHL]) are often accompanied by an expansion of B-immunoblasts, occasionally with Hodgkin/Reed-Sternberg-like (HRS-like) cells, making the differential diagnosis with classic Hodgkin lymphoma (CHL) difficult. We compared the morphologic, immunophenotypic, and molecular features of 15 TFHL and 12 CHL samples and discussed 4 challenging cases of uncertain diagnosis. Compared with CHL, TFHL disclosed more frequent sparing of subcortical sinuses, high-endothelium venule proliferation, dendritic cell meshwork expansion, T-cell atypia, and aberrant T-cell immunophenotype.
