Neuroendocrine Cancer – Liver directed therapy

Neuroendocrine Cancer – Liver directed therapy

Treatment
Neuroendocrine Neoplasms (NENs) present complex challenges to diagnosis and treatment. Even in metastatic cases spreading to the liver there are some important differences compared to the more common types of gastrointestinal tumours and pancreatic adenocarcinomas, e.g. their sometimes indolent nature and their ability to oversecrete hormones causing distinct clinical syndromes. Also, the tumours are known to be highly vascular which is a feature where growth inhibition and symptom relief may be achieved by specific 'blocking' agents - this is particularly the case with liver metastases in well differentiated Neuroendocrine Tumours (NETs). Spread to the liver may occur from NETs of the foregut, midgut as well as hindgut. NET metastases are usually multiple and of varying size. In most cases both liver lobes are affected, but widespread (miliary) seeding throughout the…

Clinical Trials of PV-10 (Rose Bengal) for the treatment of Neuroendocrine Tumours (NET)

Clinical Trials of PV-10 (Rose Bengal) for the treatment of Neuroendocrine Tumours (NET)

Clinical Trials
What is PV-10? Described above as "Oncolytic Immunotherapy" but elsewhere as "Ablative Immunotherapy", the latter indicates the method of administering the therapy i.e. tumour ablation.  It's more well known for trials in treating Melanoma where tumour ablation (albeit subcutaneous) is more common as a treatment. Scientific Description: PV-10 causes acute oncolytic destruction of injected tumors, releasing damage associated molecular pattern molecules (DAMPs) and tumor antigens that initiate an immunologic cascade where local response by the innate immune system facilitates systemic anti-tumor immunity by the adaptive immune system. The DAMP release-mediated adaptive immune response activates lymphocytes, including CD8+ T cells, CD4+ T cells, and NKT cells, based on clinical and preclinical experience in multiple tumor types. T cell function can be further augmented by combining PV-10 with immune checkpoint inhibition.  Sometimes…
