Evaluating PET/CT Imaging for Advanced Colorectal Cancer

The Role of 18F-FDG and 68Ga-FAPI PET/CT in the Diagnosis and the Efficacy Evaluation of Advanced Colorectal Cancer (peritoneal Metastasis With/without Other Metastases)

Ruijin Hospital · NCT06601075

This study is testing if two types of PET/CT imaging can help doctors see how well conversion therapy is working for patients with advanced colorectal cancer and peritoneal metastasis.

What this trial studies

This study investigates the effectiveness of 18F-FDG and 68Ga-FAPI PET/CT imaging in assessing the outcomes of conversion therapy for patients with advanced colorectal cancer, particularly those with peritoneal metastasis. Participants will undergo imaging at baseline and again after three months of therapy, with results compared to histopathological and clinical assessments. The goal is to determine the prognostic value of these imaging techniques in this patient population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histologically confirmed colorectal cancer and suspected peritoneal metastasis.

Not a fit: Patients with a history of other malignant diseases in the last five years or severe mental health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve diagnostic accuracy and treatment evaluation for patients with advanced colorectal cancer.

How similar studies have performed: Other studies have shown promising results using PET/CT imaging in cancer diagnosis, suggesting potential success for this approach.
