Clinical Scorecard: Evaluating the Effectiveness of FDG PET-CT Versus Contrast-Enhanced CT in Oesophagogastric Adenocarcinoma Patients Undergoing Neoadjuvant Chemotherapy

At a Glance

Category

Detail

Condition

Oesophagogastric Adenocarcinoma

Key Mechanisms

Neoadjuvant chemotherapy improves survival; imaging modalities assess treatment response.

Target Population

Patients with locally advanced oesophagogastric adenocarcinoma undergoing neoadjuvant chemotherapy.

Care Setting

Oncology and Radiology departments in Western institutions.

Key Highlights

  • Neoadjuvant chemotherapy is standard care for oesophagogastric adenocarcinoma.

  • FDG PET-CT is recommended for detecting occult metastatic disease.

  • CECT is the most frequently used imaging technique before surgical resection.

  • Decreased FDG avidity predicts pathological response and survival.

  • There is no consensus on the optimal imaging modality for treatment response assessment.

Guideline-Based Recommendations

Diagnosis

  • Patients should undergo FDG PET-CT after CECT to assess for metastatic disease.

Management

  • Neoadjuvant chemotherapy is recommended for patients with locally advanced disease.

Monitoring & Follow-up

  • Post-NACT imaging with both CECT and FDG PET-CT is suggested to evaluate treatment response.

Risks

  • Futile surgery may occur if occult metastatic disease is not identified.

Patient & Prescribing Data

Patients with clinical tumour stage (cT) 2 or higher and metastatic lymph nodes.

Both imaging modalities are used to predict pathological response and staging.

Clinical Best Practices

  • Utilize both CECT and FDG PET-CT for comprehensive assessment of treatment response.

  • Ensure imaging is performed contemporaneously for accurate comparison.
