Comparison of Two-Position and Four-Position Cervical Injection Techniques for Sentinel Lymph Node Mapping in Endometrial Cancer Using Methylene Blue

Summary

This clinical trial evaluates lymph node mapping in newly diagnosed endometrial cancer patients undergoing surgery. The standard technique uses a 2-point methylene blue cervical injection. The study aims to determine if increasing injection points improves mapping success.

* Individuals who have received active treatment for another malignancy within the past five years.
* Inability to successfully perform PLD (pelvic lymphadenectomy) or history of prior PLD.
* Women with multiple and confluent lymph nodes identified as positive on FDG-PET/CT (such cases are not considered stage I).

Cancer-Related Conditions

* Individuals with clinically or radiologically identified positive lymph nodes or metastatic disease.
* Individuals with a history of pelvic dissection and/or radiation therapy.
* Individuals with advanced cervical or uterine cancer.
* Individuals with T3/T4 lesions.
