OC-125 staining was absent in minimal/mild endometriosis from family planning patients but present in 52.4% of minimal/mild and 81.2% of moderate/severe endometriosis cases from chronic pelvic pain patients.

This study evaluated whether endometriotic lesion samples show OC-125 staining and whether positivity is associated with endometriosis stage, using histopathology and immunohistochemistry. Lesions were excised from 13 patients in a Family Planning program group (all minimal/mild endometriosis by histopathology) and 53 patients from a chronic pelvic pain clinic (39.6% minimal/mild and 60.4% moderate/severe). OC-125 staining was negative in all group I samples, while in group II it was positive in 52.4% of minimal/mild cases and 81.2% of moderate/severe cases, leading the authors to suggest OC-125 reflects endometriosis activity and severity. This paper is centrally about endometriosis — it tests OC-125 immunostaining across endometriotic lesion samples and relates staining frequency to disease stage and activity.

Abstract

Purpose To determine the presence of OC-125 staining in endometriotic lesions and to verify whether there is an association with endometriosis stage.

Methods

Thirteen patients from the Family Planning programs (group I) and 53 patients from the Chronic Pelvic Pain outpatient clinic (group II) were studied. Endometriotic lesions were excised from areas of endometriosis incidence and studied by histopathological assay and by immunohistochemistry for OC-125 staining.

Results

The histopathological study disclosed that all patients from group I had minimal/mild endometriosis. In group II, 39.6% had minimal/mild endometriosis, and 60.4% had moderate/severe endometriosis. OC-125 staining was negative in all samples from group I. In group II, OC-125 staining was positive in 52.4% patients with minimal/mild endometriosis and in 81.2% with moderate/severe endometriosis.

Conclusion

The data suggest that the OC-125 antibody is probably related to endometriosis activity and, consequently, to the progression and severity of the illness. Similar content being viewed by others
