Sentinel Node in Endometrial Cancer

Phase 2

Recruiting

• Conditions: Endometrial Cancer
• Interventions: Diagnostic Test: injection via TUMIR of the tracer [99mTc] Tc-albumin nanocoloid-ICG (6 mCi, 4 ml); Diagnostic Test: injection via TUMIR of [99mTc] Tc-albumin nanocoloid (6mCi, 8ml).

• Registration Number: NCT04492995
• Lead Sponsor: Judit Pich Martínez

Brief Summary

Phase II, open-label, randomized pilot study.

Patients will be randomized (1:1) to receive for sentinel node screening:

1. Radiotracer (RT) via cervical administration and TUMIR

2. Combination of RT with Indocyanine Green (RT + ICG) via cervical administration and TUMIR Patients will be followed up to 1 month after the last administration of radiotracer 70 patients will be included into the study.
