Neuroendocrine Tumors Clinical Trial
Official title:
Outcomes of Patients With Advanced Neuroendocrine Cancer (NEN) Treated With Systemic Treatment: Somatostatin Analogues, Molecular Targeted Therapy, Chemotherapy and Peptide Radioisotope Therapy - a Retrospective Analysis.
This is a retrospective study. The analysis includes patients with advanced neuroendocrine cancer (NEN) treated with systemic therapy, because of inoperable primary tumor or/and metastasis, clinical, imaging, biochemical disease progression and no standard method of treatment hormone overproduction symptoms. The data of patients with advanced NEN with histopathological confirmation is collected from medical records. The progression-free survival (PFS), overall survival (OS) and influence of various factors on survival will be estimated. The research will be conducted for above 3 years on planned group 1500 patients. The aim of the study is to estimate median OS and PFS in advanced NEN patients treated with different schedule of systemic treatment.
This is a retrospective study. The analysis includes patients with advanced neuroendocrine cancer (NEN) treated with systemic therapy, because of inoperable primary tumor or/and metastasis, clinical, imaging, biochemical disease progression and no standard method of treatment hormone overproduction symptoms. Systemic treatment including: somatostatin receptor analogues, molecular targeted therapy (sunitinib and everolimus), chemotherapy and peptide radioisotope therapy (Peptide Receptor Radionuclide Therapy). The data of patients with advanced NEN with histopathological or/and clinical or/and biochemical confirmation is collected from medical records. Neuroendocrine cancer from digestive system, respiratory system and another rarely occurring cancer including cancer connected with genetic syndromes like: MEN1, MEN2, VHL, NF1, SDHx will be included. The progression-free survival (PFS), overall survival (OS) and influence of various factors on survival will be estimated. Analyzed factors: age, sex, ethnicity, specific symptoms at the time of diagnosis, carcinoid heart disease, level of 5HIAA in DZM, level of CgA, liver test, size of tumor, cell differentiation of tumor based on Ki-67 index, liver metastases. The research will be conducted for above 3 years since July 2019 till December 2022 on planned group 1500 patients. The aim of the study is to estimate median OS and PFS in advanced NEN patients treated with different schedule of systemic treatment. The second goal is to create clinical practice recommendation based on potential prognostic factors of OS and PFS due to type of therapy in different NEN subgroups. ;
