Pancreatic Neuroendocrine Tumor: The Case Report of a Patient with Germline Mutation and Tumor Analysis Using Single-Cell RNA Sequencing

Abstract

Methods: This article describes a clinical case characterized by a progressive growth of nonfunctional PanNET requiring surgical treatment in a patient with a germline mutation, previously not reported in PanNETs. The patient underwent whole exome sequencing and single-cell RNA sequencing.

Results: The patient underwent surgical treatment. We confirmed the presence of the germline mutation and also detected the germline mutation . The cellular composition of the PanNET was analyzed using single-cell sequencing, and the main cell clusters were identified. We analyzed the tumor genomics, and used the data to define the effect the germline mutation had.

Conclusions: Analysis of the mutational status of patients with PanNET may provide additional data that may influence treatment tactics, refine the plan for monitoring such patients, and provide more information about the pathogenesis of PanNET. PanNET research using scRNA-seq data may help in predicting the effect of therapy on neuroendocrine cells with mutations.
