[Study on echo pattern of endometrial cancer (author's transl)]

Area of Science:

• Gynecologic Oncology
• Diagnostic Imaging
• Pathology

Context:

• Endometrial cancer diagnosis lacks established ultrasound imaging guidelines.
• Limited literature exists on ultrasound's diagnostic efficacy for endometrial cancer.
• This study analyzes ultrasound findings in pathologically confirmed endometrial cancer cases.

Purpose:

• To investigate the diagnostic efficacy of ultrasound imaging for endometrial cancer.
• To correlate ultrasound-detected echo patterns with clinical stage, growth patterns, and histological features of endometrial cancer.
• To explore ultrasound's utility in identifying coexistent lesions in endometrial cancer.

Summary:

• Analyzed 59 endometrial cancer echograms, classifying internal echoes into four patterns (anechoic, linear, cystic, massive).
• Type 3 (cystic) and Type 4 (massive) patterns occurred in 25.4% and 40.7% of cases, respectively.
• Significant correlations were found between echo patterns and clinical stage (p<0.05) and growth pattern (p<0.05), but not histological type or grade.
• Ultrasound identified coexistent lesions, including ovarian metastases.

Impact:

• Establishes a foundation for using ultrasound in endometrial cancer diagnosis.
• Highlights the potential of specific echo patterns (Type 3 & 4) in predicting advanced clinical stages (II-IV).
• Demonstrates ultrasound's value in assessing tumor growth patterns and detecting metastatic disease.
