From the Guidelines
RBS 2418 is not a recognized or approved treatment for metastatic grade 2 pancreatic neuroendocrine tumors (NETs). Currently, there is no evidence that this compound exists as a legitimate cancer therapy. For metastatic pancreatic NETs, standard treatments include somatostatin analogs (like octreotide LAR 30mg monthly or lanreotide 120mg monthly), targeted therapies (such as everolimus 10mg daily or sunitinib 37.5mg daily), peptide receptor radionuclide therapy (PRRT) with Lutathera for somatostatin receptor-positive tumors, and in some cases, chemotherapy regimens like capecitabine with temozolomide 1.
Treatment Options
Treatment selection depends on tumor characteristics, disease burden, progression rate, and patient factors. The choice of chemotherapy is mainly based on the tumor growth rate and Ki-67, with STZ-based and TEM-based therapies providing similar overall response rates (ORRs) 1.
Multidisciplinary Management
Pancreatic NETs require management by a multidisciplinary team including oncologists, surgeons, and nuclear medicine specialists. If you're exploring treatment options for pancreatic NETs, consult with healthcare providers specializing in neuroendocrine tumors to develop an appropriate, evidence-based treatment plan tailored to your specific situation. Guidelines for NF pan-NENs vary, but a detailed and critical analysis of the controversial points is necessary to provide the best treatment options 1.
Recent Studies
Recent studies, such as the systematic review on the efficacy of streptozotocin in managing pancreatic neuroendocrine neoplasms, provide scientific evidence for the STZ-5FU regimen, often retrospective and frequently analyzing small series 1. Despite these limitations, the efficacy of this treatment is well-established, and it is included in all guidelines as a therapeutic option.
Evidence-Based Treatment
In conclusion, the treatment of metastatic grade 2 pancreatic NETs should be based on the most recent and highest quality evidence available, and RBS 2418 is not a recognized treatment option. Patients should consult with healthcare providers specializing in neuroendocrine tumors to develop an appropriate, evidence-based treatment plan tailored to their specific situation, considering the latest guidelines and studies, such as those published in Cancer Treatment Reviews 1 and Annals of Oncology 1.
From the Research
Treatment Options for Metastatic Grade 2 Pancreatic Neuroendocrine Tumors
- There is no direct evidence that Rbs 2418 can cure a metastatic grade 2 pancreatic neuroendocrine tumor (PanNET) 2, 3, 4, 5, 6.
- However, studies have shown that capecitabine and temozolomide (CAPTEM) can be an effective treatment option for metastatic PanNETs, with a high response rate and durable progression-free survival 3, 4, 5.
- A study published in 2022 found that alternating sunitinib and CAPTEM was well tolerated and associated with similar median progression-free survival in grade 1/grade 2 PanNETs 2.
- Another study published in 2011 found that the combination of capecitabine and temozolomide was associated with an exceptionally high and durable response rate in metastatic endocrine carcinomas of the pancreas 3.
- A case report published in 2012 described a young woman with an unresectable pancreatic neuroendocrine tumor who was successfully down-staged using a chemotherapy regimen of capecitabine and temozolomide with minimal toxicity 4.
- A study published in 2020 compared temozolomide alone or combined with capecitabine for the treatment of advanced pancreatic neuroendocrine tumors and found that the combination of temozolomide and capecitabine might achieve a higher response rate than temozolomide alone 5.
- A multicenter retrospective review published in 2021 found that temozolomide-containing regimens, particularly CAPTEM, were effective in treating grade 3 gastroenteropancreatic neuroendocrine neoplasms, with a response rate of 36% and a median time to treatment failure of 3.6 months 6.
Efficacy of CAPTEM in Metastatic PanNETs
- The efficacy of CAPTEM in metastatic PanNETs has been demonstrated in several studies, with response rates ranging from 34% to 70% 3, 5.
- The combination of capecitabine and temozolomide has been shown to be well tolerated, with minimal toxicity 3, 4.
- However, the optimal treatment strategy for metastatic PanNETs remains unclear, and further studies are needed to determine the efficacy of CAPTEM in this setting 2, 5, 6.
