Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

stage III/IV gastrointestinal cancer patients

Arm Description

The study group (Personalized drug sensitivity test) was treated according to the physician's opinion. Tumor tissues are obtained during the surgery or via biopsy with informed consent, for the purpose of ex vivo assay.

Outcomes

Primary Outcome Measures

ex vivo Maximal Inhibition Index (MI)
The effectiveness of each therapeutic regimen was evaluated and quantified using the formula: Maximum Inhibition (MI)=N0/Nd, where N0 and Nd denotes the number of EpCAM+ EdU+ epithelial cells in the wells of control or withthe drug at concentration C0, respectively.

Secondary Outcome Measures

Disease Control Rate(DCR)after chemotherapy
Disease Control Rate(DCR)after chemotherapy.
Progression free survival (PFS) after chemotherapy
Progression free survival (PFS) after chemotherapy

5. Study Description

Brief Summary
Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. Study objectives: Personalized drug sensitivity test for late stage,potentially operable gastrointestinal cancer using patient derived primary cell culture. Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. The study will collect primary tumor tissues from stage III/IV gastrointestinal cancer patients who underwent emergency surgeries, and then establish the primary tumor cell library for ex vivo chemotherapy drug sensitivity test in order to: Compare the ex vivo Maximal Inhibition Index(MI) and Drug Sensitivity Index (DSI) with patient's Overall Response Rate (ORR) Provide research support for future clinical treatment. This ex vivo method applies to single or combination drug regimen, and does not require prior knowledge of the specific mechanism for individual patient's drug sensitivity. Previous research as well as literature studies support the close relationship between ex vivo drug sensitivity and in vivo drug response.
Detailed Description
The patient underwent surgery to remove tumor and agreed to take out the abdominal tumor specimens for research. A section of each sample was removed for the generation of PDX models as described early.The rest of the tumor cells were expanded using ex vivo drug sensitivity assay. The drugs used in the study were 5-fluorouracil, Oxaliplatin, and irinotecan at C0 = 10 mM, 2.5 mM and 0.02 mM, respectively. They were applied either as single agents or in combinations of 5-fluorouracil and Oxaliplatin, 5-fluorouracil and irinotecan, or all three agents, or others. After 7 days of treatment, the tumor cells were stained with EdU, Hoechst and EpCAM with the Cell Quantitative Detection Kit. Images were acquired with an automated microscopic image-scanning system and analyzed with the built-in software.
