Molecular Profiling of Low-Grade Appendiceal Mucinous Neoplasms (LAMN).
Genes Chromosomes Cancer
October 2024
Low-grade appendiceal mucinous neoplasia (LAMN) represents a relatively rare tumor of the appendix typically diagnosed incidentally through appendectomy for acute appendicitis. In cases where perforation occurs, mucinous content may disseminate into the abdominal cavity, leading to the development of pseudomyxoma peritonei (PMP). The primary objective of this study was to elucidate the molecular characteristics associated with various stages of LAMN and PMP.

- Whole Exome Sequencing (WES) is a powerful tool in cancer diagnostics that allows for comprehensive analysis of genes, improving the detection of complex biomarkers compared to traditional panel-based methods.
- A study analyzing tissue specimens across 21 NGS centers showed that, although there was a 76% agreement in somatic variant calling, refining filtering criteria improved this to 88%, highlighting the importance of filter settings in variant detection.
- The reliability of detecting specific genomic changes (like CNAs and complex biomarkers) varied among labs, emphasizing the need for improved bioinformatics processes and collaborative testing to minimize discrepancies in future analyses.
This case report describes the efficacy of selpercatinib, a selective RET inhibitor, in an unusual case of large-cell neuroendocrine pancreatic carcinoma (LCNEPAC) harboring a CCDC6::RET fusion. A 56-year-old male with a history of multiple lines of systemic therapies exhibited marked clinical amelioration shortly after initiating selpercatinib within the LOXO-RET-17001 study (ClinicalTrials.gov ID: NCT03157128, first posted: 2017-05-17).

Objectives: In order to better understand the molecular pathogenesis of cutaneous acral CD8+ TLPD and to identify further discriminatory markers to differentiate this lymphoma subtype from other CD8+ cutaneous lymphomas, we analysed five cases of cutaneous acral CD8+ TLPD for putative molecular alterations.
Purpose: Providing patient access to precision oncology (PO) is a major challenge of clinical oncologists. Here, we provide an easily transferable model from strategic management science to assess the outreach of a cancer center.
Methods: As members of the German WERA alliance, the cancer centers in Würzburg, Erlangen, Regensburg and Augsburg merged care data regarding their geographical impact.
