New Research on Early Detection of Endometriosis

A recent study presented at The Society for Reproductive Investigation Meeting highlighted initial results from patients with suspected endometriosis who underwent imaging with a SPECT-CT camera followed by laparoscopic surgery. This study revealed that the use of 99mTc-maraciclatide shows promise as a non-invasive test for early-stage detection of endometriosis.

Preliminary Findings

The preliminary findings from the study indicated that 99mTc-maraciclatide has the potential to:

  • Identify superficial peritoneal endometriosis, a common subtype that makes up 80% of endometriosis cases. Currently, this type can only be accurately diagnosed through surgery. The imaging test correctly detected this subtype in patients who were later confirmed to have it through surgery.
  • Highlight areas of activity in patients with deep endometriosis and endometrioma, which are cysts commonly found in the ovaries.

Additionally, a case study presented showcased a patient with superficial peritoneal endometriosis that was not identified through ultrasound but was visualized using 99mTc-maraciclatide and later confirmed during surgery.

Ongoing Study and Potential Impact

Professor Christian Becker and Professor Krina Zondervan are leading an ongoing study involving 20–25 patients to further explore the use of 99mTc-maraciclatide in diagnosing endometriosis. The study is expected to be completed later this year.

99mTc-maraciclatide is a tracer that binds to αvβ3 integrin, a cell adhesion protein, and images angiogenesis, which is crucial for the growth of endometriotic lesions.

Implications of the Study

Davd Hail, CEO of Serac Healthcare, expressed optimism about the potential of maraciclatide as a non-invasive tool for diagnosing early-stage endometriosis. Early detection is significant as it can’t be achieved through other imaging methods, leading to delays in diagnosis and treatment.

Both Becker and Zondervan emphasized the importance of early detection in improving outcomes for women with endometriosis. They believe that having a novel imaging tool can significantly impact the management of this common and debilitating condition.

Overall, the study’s findings suggest that 99mTc-maraciclatide has the potential to revolutionize the early detection and diagnosis of endometriosis, ultimately improving the quality of life for millions of women worldwide.
