Study Summary

A prospective cohort imaging study in a single institution to evaluate 68Ga- FAPI-46 and 18F-FDG PET/CT imaging for detecting recurrent tumor lesions in patients of ovarian cancer with CA125 elevation from complete response after therapy

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Pathologically proven ovarian cancer with complete response after therapy

  • Elevation of serum CA125 value above the normal range (>35 U/mL) or doubling of serumCA125 value within the normal range
  • ECOG performance status grade 0 or 1 and willing to receive further therapy if diseaserecurrence is confirmed
  • Willing to enter this prospective study with signed informed consent form

Exclusion

Exclusion Criteria:

  • Patients with history of other malignancy
  • Patients who are pregnant or lactating

Study Description

Ovarian cancer is the eighth most common cancer worldwide in females and usually diagnosed at an advanced stage. Serum cancer antigen 125 (CA125) is widely used in ovarian cancer. An elevation in CA125 levels can precede a clinically apparent recurrence by 3 to 6 months and 18F-FDG PET/CT can modify management in approximately half of these patients. However. 18F-FDG PET/CT may yield false negative results. 68Ga-FAPI-46 PET/CT shows potential here. This study is to assess the diagnostic performances of 68Ga-FAPI-46 and 18F-FDG PET/CT for ovarian cancer recurrence in patients with CA125 elevation from complete response after therapy.
