Brief Summary

Brief Summary: Machine Learning-Driven Noninvasive Screening of Transcriptomics Liquid Biopsies for Early Diagnosis of Occult Peritoneal Metastases in Locally Advanced Gastric Cancer Gastric cancer, commonly known as stomach cancer, is a significant health issue worldwide, especially when it progresses to an advanced stage. One of the major challenges in treating locally advanced gastric cancer (LAGC) is the detection of occult (hidden) peritoneal metastases. These metastases are cancer cells that spread to the peritoneum (the lining of the abdominal cavity) but are not easily detectable with standard imaging techniques or during surgery. Early and accurate detection of these hidden metastases can significantly improve treatment strategies and outcomes for patients. This clinical study explores an innovative approach to tackle this problem using machine learning (ML) technology and liquid biopsies. Liquid biopsies are a noninvasive method that involves analyzing blood samples to detect cancer-related biomarkers, such as circulating tumor DNA or RNA. This study specifically focuses on the transcriptomics of liquid biopsies, which refers to the analysis of RNA molecules to understand the gene expression profiles associated with cancer. Hypothesis The hypothesis of this study is that machine learning algorithms can effectively analyze transcriptomics data from liquid biopsies to detect occult peritoneal metastases in patients with locally advanced gastric cancer. By doing so, this method could provide a noninvasive, accurate, and early diagnosis of metastases, which are otherwise difficult to identify through traditional methods. Study Design

  • Improved Treatment Planning: Early detection allows for more tailored and effective treatment strategies, potentially including more aggressive therapies or surgical interventions when necessary.
  • Better Patient Outcomes: With earlier and more accurate diagnosis, patients have a higher chance of receiving timely and appropriate treatments, which can improve survival rates and quality of life.
  • Noninvasive Screening: Liquid biopsies are less invasive than traditional biopsy methods, reducing the physical and psychological burden on patients.
  • Cost-Effectiveness: Early detection and treatment can potentially reduce the overall cost of care by preventing the need for more extensive and expensive treatments at later stages of the disease. Conclusion This clinical study represents a promising step forward in the fight against gastric cancer. By integrating machine learning with noninvasive liquid biopsy techniques, it aims to provide a new tool for the early detection of occult peritoneal metastases, ultimately improving outcomes for patients with locally advanced gastric cancer. The success of this study could pave the way for broader applications of machine learning in cancer diagnostics and personalized medicine.

Study Population

The study population will consist of patients diagnosed with locally advanced gastric cancer (LAGC). This specific group of patients is chosen because they are at a critical stage where early detection of occult peritoneal metastases can significantly impact treatment planning and outcomes.

You may qualify if:

  • Diagnosis of Locally Advanced Gastric Cancer (LAGC): Patients must have a confirmed diagnosis of locally advanced gastric cancer, as determined by standard diagnostic procedures such as imaging and histopathological examination.
  • Age: Participants must be adults aged 18 years or older. Consent: Patients must be able to provide informed consent to participate in the study.
  • Adequate Organ Function: Participants should have adequate bone marrow, liver, and kidney function as defined by specific laboratory criteria (e.g., specific levels of hemoglobin, platelet count, liver enzymes, and creatinine clearance).
  • Performance Status: Patients should have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2, indicating they are fully active, restricted in physically strenuous activity but ambulatory, or capable of all self-care but unable to carry out any work activities.
  • Willingness to Provide Blood Samples: Participants must be willing to provide blood samples at specified time points throughout the study.
  • Previous Treatment: Patients who have received prior treatments for gastric cancer (e.g., chemotherapy, radiation therapy, or surgery) may be included, provided there is a sufficient washout period as determined by the study protocol.

You may not qualify if:

  • Distant Metastases: Patients with confirmed distant metastases (beyond the peritoneum) are excluded.
  • Other Malignancies: Individuals with a history of other malignancies within the past five years, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the cervix.
  • Severe Comorbid Conditions: Patients with severe or uncontrolled comorbid conditions, such as significant cardiovascular disease, uncontrolled diabetes, severe infections, or other conditions that could interfere with the study participation or outcomes.
  • Pregnancy and Lactation: Pregnant or lactating women are excluded due to potential risks to the fetus or infant.
  • Immunocompromised Status: Patients who are immunocompromised, such as those with HIV/AIDS, or who are receiving immunosuppressive therapy.
  • Concurrent Participation in Other Clinical Trials: Individuals currently participating in another clinical trial that could interfere with this study's procedures or outcomes.
  • Allergies to Study Materials: Patients with known allergies to any components of the study materials used for liquid biopsy processing and analysis.
  • Non-compliance: Individuals deemed unable or unwilling to comply with the study procedures and follow-up requirements.
