A phase II trial of Cabozantinib medication in patients with advanced, high-grade neuroendocrine neoplasms, which are either well-differentiated neuroendocrine tumors or poor-differentiated neuroendocrine carcinoma but with a low proliferation rate. Both neuroendocrine neoplasms are insensitive against the available chemotherapy choice, making the newly investigated medication a new hope for better management of these subtypes.
- Conditions
- We will include patients with NET G3 in upto four different antitumoral therapies and NEC Ki67 low after failure of standard treatment with conventional chemotherapy.Therapeutic area: Diseases [C] - Cancer [C04]
