Outcomes Post-Laparoscopic Intervention for Accessory and Cavitated Uterine Masses: A Review and a Molecular Insight

Area of Science:

• Gynecology
• Reproductive Medicine
• Surgical Oncology

Background:

• Accessory and cavitated uterine masses (ACUM) are rare Mullerian anomalies characterized by isolated, cavitated masses lined with endometrial epithelium.
• These anomalies can cause significant symptoms, including refractory dysmenorrhea.

Purpose of the Study:

• To review current literature on laparoscopic surgical techniques for ACUM.
• To present a case report of successful laparoscopic-assisted intervention for ACUM.
• To investigate potential genetic underpinnings of ACUM through targeted sequencing.

Main Methods:

• A comprehensive literature search was conducted using Ovid MEDLINE and Embase.
• Studies focusing on laparoscopic surgery for ACUM and its impact on fertility, menorrhagia, or dysmenorrhea were selected.
• A case of ACUM underwent targeted genetic sequencing for cancer-associated mutations.

Main Results:

• Analysis of 25 articles involving 75 patients revealed dysmenorrhea in 100% of cases.
• Laparoscopic resection improved symptoms in 84% of patients.
• The ACUM mass in the case report showed somatic mutations in RET and HRAS genes.

Conclusions:

• Laparoscopic surgery is an effective, common first-line treatment for ACUM, though techniques are not standardized.
• This is the first case to demonstrate mutations in ACUM, suggesting a role for cancer-associated somatic mutations in their development.
• Further genetic analysis of ACUM is recommended to understand lesion formation and standardize treatment.
