Intraperitoneal tumors of low malignant potential present diagnostic challenges due to their widespread nature yet benign behavior. This review confirms excellent outcomes without aggressive treatment, suggesting a primary peritoneal origin.

Area of Science:

Gynecologic Oncology
Pathology
Surgical Oncology

Background:

Intraperitoneal tumors of low malignant potential pose clinical challenges due to conflicting indicators of aggressiveness.
These tumors often exhibit wide peritoneal distribution but possess benign histopathology and clinical course.

Purpose of the Study:

To review a cohort of 154 patients with intraperitoneal tumors of low malignant potential.
To elucidate the behavior, origin, and optimal management of these perplexing neoplasms.

Main Methods:

Retrospective review of 154 cases with follow-up ranging from 2 to 40 years.
Analysis of tumor distribution, clinical course, treatment modalities, and patient outcomes.

Main Results:

Tumors can present as diffuse peritoneal disease with minimal ovarian involvement, despite a tendency to originate in the ovary.
Excellent patient survival (152/154) was observed without adjunctive therapy, with contraindications for such interventions.
One death occurred following intraperitoneal isotope therapy, highlighting potential iatrogenic harm.

Conclusions:

Intraperitoneal tumors of low malignant potential are best conceptualized as diffuse primary peritoneal tumors.
A proposed etiology involves irritating agents from the lower genital canal, analogous to endometriosis.
These low-grade, in situ tumors are compatible with prolonged survival and excellent prognosis without aggressive treatment.
