Radiation therapy improves cancer cure rates by killing cancer cells but it also contributes to long-term side effects in cancer survivors by unintentionally damaging normal organs such as the intestine. This research will what side effects patients with cancer experience, if high dose vitamin C helps reduce these side effects, and if high dose vitamin C increases the survival of patients with pancreatic cancer. We will meet with patients during the study to better understand their experience during their cancer treatment. In the long term, our research could provide a new way help cancer survivors avoid many permanent side effects of cancer treatments.

A Phase 1, First-in-human Clinical Trial of [212Pb] VMT-alpha-NET Using a Forward Dosimetric Planning Technique to Treat Refractory or Relapsed Neuroendocrine Tumors

This is a safety study to determine the recommended dose to test in clinical trials. The study involves two treatments with 212Pb (212-lead) VMT-α-NET. This is a safety study only; it will most likely not provide therapeutic benefit.

INTRODUCTIONThe available data for the safety and efficacy of repeat peptide receptor radionuclide therapy (PRRT) are almost exclusively from European centers. We present an updated experience with repeat PRRT in a cohort of US patients with neuroendocrine tumors (NETs) at our NET center of excellence.METHODSWe used our single-center longitudinal NET registry to identify patients who had been previously treated with at least one dose of PRRT (PRRT 1, either ¹⁷⁷Lu DOTATATE or ⁹⁰Y DOTATOC) and following radiographic disease progression were re-treated with a second course of PRRT (PRRT 2). We reviewed patient, tumor and treatment characteristics, objective response rates, and toxicities after PRRT 1 and PRRT 2.RESULTSA total of 11 patients were included in the analysis. 45.5% (5/11) of patients received ¹⁷⁷Lu DOTATATE PRRT only, both for PRRT1 and PRRT 2, while 54.5% (6/11) of patients received ⁹⁰Y DOTATOC PRRT for PRRT1. At first restaging scan after PRRT2 (3-6 months), 18.2% (2/11), 36.4% (4/11), and 27.3% (3/11) of patients had PR, SD, and PD, respectively; 2/11 patients (18.2%) died before the first restaging scan. Therefore, 5/11 (45.5%) patients were noted to have disease progression. Median PFS for PRRT1 was 25.4 months and median PFS for PRRT2 was 13.1 months (p = 0.0001). We did not find a statistically significant difference between the occurrence of short and long-term hematological toxicities as well as renal toxicity after PRRT1 and PRRT2.CONCLUSIONWe show that repeat PRRT may benefit select patients and have an acceptable safety profile. In our cohort, PFS was significantly lower after PRRT2 as compared to PRRT1.

Abstract 3928: Genomic landscape and estimation of immune infiltration of soft tissue sarcoma histology subtypes from the ORIEN network

AbstractSarcomas encompass a group of malignant diseases arising from mesenchymal origins. Given their rarity and diversity, a fundamental understanding of the genomic underpinnings for many sarcoma subtypes is still lacking. Studies are often limited to one or several of the more common subtypes or a narrow evaluation of a broader sampling. We therefore report on one of the largest comprehensive omics evaluation in sarcomas to date, including whole exome sequencing (WES; n = 1170) and RNA-sequencing (n = 983) of tissues from 29 different sarcoma histologic subtypes collected at 13 institutions in the US as part of the Oncology Research Information Exchange Network (ORIEN). We identified recurrent somatic mutations previously identified in sarcomas (e.g. TP53, KIT) as well as other cancer types (e.g. BRCA1). The burden of putatively pathogenic driver point mutations was higher in metastatic samples (median = 3) as compared to primary tumor samples (median = 2; p < 0.001). We observed frequent copy number alterations including whole genome doubling more commonly in metastatic compared to primary tumors (23.4% vs. 16.9%; p = 0.0.25). Inspection of gene expression dimensionality reduction (UMAP) showed separation of gastrointestinal stromal tumors (GISTs), leiomyosarcomas, myxoid liposarcomas, and well/de-differentiated liposarcomas from the other histologies. Differential expression analysis for these four histologies with gene set enrichment analysis highlights the diversity of disease-specific pathways and need for sarcoma subtype-specific translational focus. Estimation of immune cell abundances based on RNA-seq followed by hierarchical clustering identified five immune subtypes. The subtypes ranged from low (clusters A, B) to high (clusters D, E) immune infiltration with higher abundance of T, B, Natural Killer (NK), and myeloid cells (FDR < 0.01). Intermediate immune group C was predominantly composed by GISTs and marked by an enrichment for NK cells (FDR < 0.01) compared to all groups except the immune “hot” group E; however, this immune group exhibited modest infiltration by other immune cell types. Notably, we observed significant differences in the overall survival of patients with sarcomas in immune enriched (C, D, E) compared to immune depleted clusters (A, B; p = 0.002). In summary, we report the genomic and expressional landscape of over 1000 sarcomas, representing one of the largest comprehensive profiling efforts in this disease. We identify the mutational and copy number variation landscape and observe differences between primary and metastatic samples. We highlight expression pathways that are enriched in histologic subtypes that cluster most distinctly from others, providing a subtype-specific roadmap for further translational efforts. Finally, we define immune enriched or depleted sarcoma subgroupings that carry a prognostic impact.Citation Format: Alex C. Soupir, Oscar E. Ospina, Dale Hedges, Jamie K. Teer, Michael D.
