Current treatment strategies for low-grade tumors include surgical resection, peptide radionucleotide receptor therapy, and somatostatin analogues, while high-grade and recurrent tumors may receive cytotoxic chemotherapy. These limited treatment options are linked to the lack of representative models that can both reflect the biology of the tumor and are amenable to mid-to-high throughput experimentation. Cell line generation is challenging considering the indolent nature of primary lesions, although some attempts have been successful using a variety of methods and include the primary P-STS line and those derived from metastatic lesions, including GOT1, CNDT2.5, and HC45. Patient-derived modeling, including organoids and xenografting, have allowed for multicellular and 3D representations of the original tumor. These specific models allow for multicellular populations derived from the tumor, providing better tumor representation for use in drug screening and\n                    <jats:italic>in vitro<\/jats:italic>\n                    assays. Currently, there are limited, although increasing, published models of siNETs implanted as xenografts in mice and zebrafish. As these cellular and animal models provide insights into siNET biology, theragnostic modeling has provided key information on the clinical progression and treatment of this disease. Significant strides toward more representative models have been made throughout the last decade. In this review, details of these attempts as well as future directions and strategies for more robust models will be addressed.\n                  <\/jats:p>","DOI":"10.1530\/eo-24-0038","type":"journal-article","created":{"date-parts":[[2024,10,23]],"date-time":"2024-10-23T13:33:55Z","timestamp":1729690435000},"update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-15","source":"Crossref","is-referenced-by-count":0,"title":["Multifaceted modeling of small intestinal neuroendocrine tumors"],"prefix":"10.1530","volume":"4","author":[{"given":"Stephen Gabriel","family":"Andrews","sequence":"first","affiliation":[{"name":"Neuroendocrine Cancer Therapy Section, Surgical Oncology Program, Center for Cancer Research, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven D","family":"Forsythe","sequence":"additional","affiliation":[{"name":"Neuroendocrine Cancer Therapy Section, Surgical Oncology Program, Center for Cancer Research, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James P","family":"Madigan","sequence":"additional","affiliation":[{"name":"Neuroendocrine Cancer Therapy Section, Surgical Oncology Program, Center for Cancer Research, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7538-9431","authenticated-orcid":true,"given":"Samira Mercedes","family":"Sadowski","sequence":"additional","affiliation":[{"name":"Neuroendocrine Cancer Therapy Section, Surgical Oncology Program, Center for Cancer Research, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"key":"bib1","series-title":"Nature Reviews.
