Prediction of Drug Response in Gastric Cancer Based on 3D Bioprinting

January 19, 2025 updated by: Peking Union Medical College Hospital

Research on the Value of Predicting Drug Efficacy Based on 3D Bioprinting for Constructing in Vitro Gastric Cancer Models

The therapeutic regimens for adjuvant and neoadjuvant chemotherapy in gastric cancer (GC) predominantly hinge on clinical experience. Consequently, there is an imperative need for preclinical models to facilitate the guidance of individualized medicine. The investigators plan to establish three-dimensional (3D) bioprinted GC models derived from surgically resected tumor tissues of GC patients. These in vitro 3D models will be subjected to treatment with the identical chemotherapy drugs administered to the corresponding patients from whom the models are sourced. The sensitivity of the chemotherapy drugs will be assayed within the in vitro models, and the actual response to chemotherapy in patients will be meticulously evaluated. This observational study aims to substantiate the potential utility of 3D bioprinted tumor models in prognosticating the response to chemotherapy in GC.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Individuals with a clinical and pathological diagnosis of gastric cancer are deemed eligible for this study. Clinical physicians will meticulously record the medical histories, restricting inclusion to patients aged 18 years and above. Exclusion criteria encompass individuals with concomitant malignancies or severe comorbidities. Patients incapable of providing autonomous informed consent are ineligible for participation. All participants will undergo adjuvant or neoadjuvant chemotherapy, followed by surgical resection, as part of the treatment protocol for localized gastric cancer.

Description

Inclusion Criteria:

  • More than 18 years old
  • Patients previously diagnosed with gastric cancer or confirmed by pathology as having gastric cancer postoperatively.
  • Patients who have undergone preoperative imaging examinations, including plain and contrast-enhanced CT scans of the chest, abdomen, and pelvis, as well as gastric MRI for tumor staging, and who are planned for preoperative (neo)adjuvant therapy after multidisciplinary team (MDT) discussion; patients with advanced gastric cancer who are confirmed by postoperative pathology to require (neo)adjuvant therapy.
  • The patient or their family members are able to comprehend the research protocol and are willing to participate in this study, providing written informed consent.

Exclusion Criteria:

  • History of other malignancies or serious medical conditions
  • Inability to provide independent informed consent

Intervention / Treatment

Intervention / Treatment

Procedure: surgical resection
Surgical resection will be performed for locoregional lesions .

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Correlation of Drug Sensitivity in In Vitro Tumor Models with Clinical Response in Patients
Time Frame: From enrollment to end within 2 weeks
  1. Response of 3D tumor models to chemotherapy drugs identical to those administered to corresponding patients: Researchers will establish and culture 3D printed gastric cancer models and treat them with the same chemotherapy drugs used for the corresponding patients. Following treatment, the viability of the 3D tumor models will be observed, and the IC50 of each drug will be calculated. The correlation between the sensitivity of the 3D models and the patients' responses will be analyzed.
  2. Response of Gastric Cancer Patients to Neoadjuvant Chemotherapy: For patients who undergo neoadjuvant chemotherapy prior to surgery, the response to such treatment will be assessed based on clinical imaging results, the Mandard-TRG criteria, and the RECIST score.
From enrollment to end within 2 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Response of Gastric Cancer Patients to Adjuvant Chemotherapy
Time Frame: Up to 2 years
The response to adjuvant chemotherapy will be assessed based on disease-free survival (DFS) or Overall Survival (OS). Regular follow-ups will be conducted. DFS is defined as the interval between the date of surgery and the date of the last follow-up or the date of recurrence/progression.Overall survival (OS) is delineated as the temporal span from the date of surgery to the date of death or the date of the last follow-up, whichever occurs first.
Up to 2 years
