In Vitro Organoid Drug Sensitivity-Guided Treatment for Advanced Pancreatic Neuroendocrine Tumor

Ruijin Hospital20 enrolled

Overview

The purpose of this study is to explore whether chemotherapy and targeted-therapy regimens guided by organoid drug sensitivity test can improve the outcomes of non-resectable locally advanced and metastatic Pancreatic neuroendocrine tumors. At the same time, this study will evaluate the successful stablishment rate of organoid from biopsy tissue , and explore the concordance between drug sensitivity test results and patients' treatment response

Twenty non-resectable locally advanced and metastatic pancreatic neuroendocrine Tumor(p-NET) patients who should receive palliative treatment will be enrolled in this study. Baseline information of the enrolled patients including medical history, physical examination records and clinical examination records will be collected. Tumor material of those patients will be obtained from Pancreatic endoscopic biopsies or surgical resection. Patient-derived organoids (PDOs) will be established and cultured from p-NET tumor specimens. PDOs will then be treated with drugs of the chemotherapeutic and targeted therapeutic regimens for p-NET. Organoid size and growth will be monitored before and after the treatment, and dose-response curves will be generated. As for the assessment of clinical outcomes of patients, treatment responses will be assessed by biomedical imaging according to the Response Evaluation Criteria in Solid Tumors (RECIST1.1). Consistency between treatment responses in PDO models and clinical outcomes of patients will be assessed by correlation analysis.

Outcomes

Primary Outcomes

Objective Response Rate

Percentage of patient's measurable disease who have achieved either complete response (CR) or partial response (PR) according to RECIST 1.1.

Time frame: 1-2 years

Secondary Outcomes

Progressive free survival

The time from initiation of treatment to the occurrence of disease progression or death.

Time frame: 1-2 years

Overall survival time

The time from the date of randomization to the date of death for any cause. Patients will be followed until their date of death or until final database closure.

Time frame: 2 years

The successful establishment rate of organoids

The rate of organoid successfully cultured in all the samples collected.

Time frame: 1-2 years

Concordance between drug sensitivity test results and patients' treatment response

To assess the accuracy of drug sensitivity test in both group. The number of patients with correct prediction of treatment response by organoid drug-sensitivity test divided by the number of patients underwent chemotherapy

Time frame: 1-2 years
