#4481 Predicting peptide receptor radionuclide therapy (PRRT) response through the landscape of the immune microenvironment in neuroendocrine tumours

Introduction: Neuroendocrine tumours (NETs) often have poor prognosis upon metastasis. Peptide receptor radionuclide therapy (PRRT) is a novel treatment leveraging targeted cytotoxicity of radionuclides to efficiently address primary and metastatic tumours of NETs.

#4289 Temozolomide-associated hypermutation and response to immunotherapy in advanced pulmonary neuroendocrine tumours

Introduction: Temozolomide (TMZ) cytotoxicity depends on an intact DNA mismatch repair (MMR) pathway and low levels of O6-methylguanine DNA methyltransferase (MGMT). However, absence of MGMT-mediated repair coupled with defective MMR (dMMR) may lead to enrichment of C:G to A:T transitions throughout the genome, a marked increase in tumour mutational burden (TMB), and loss of TMZ-induced cytotoxicity. This resistance mechanism is called TMZ-associated hypermutation (TAH). Theoretically, this effect could lead to sensitivity to checkpoint inhibitor immunotherapy.
