Scaling cervical cancer screening in Mozambique: analysis of loop electrosurgical excision procedure (LEEP) specimens.
Objectives: As cervical cancer screening programs are implemented and expanded, an increasing number of women require loop electrosurgical excision procedure (LEEP) for treatment of pre-invasive cervical disease. Our objective was to describe the pathological results of LEEP specimens performed as part of the MULHER study and identify factors associated with positive LEEP margins.
Methods: The MULHER study enrolled 9014 women who underwent HPV testing followed by visual assessment for treatment (VAT) using visual inspection with acetic acid (VIA) and thermal ablation for those with positive results. Participants with lesions ineligible for ablation underwent LEEP. Pathology reports were reviewed for specimen size/volume, number of fragments, pathological diagnosis and margin status. Multivariable regression analysis was performed to identify variables associated with positive LEEP margins.
Results: 169 participants underwent LEEP. The median age was 38 years (range 30-49). 65.1% were women living with HIV. Pathological diagnosis was available for 154 patients and included cancer (n=6, 3.9%); cervical intraepithelial neoplasia (CIN) 2/3 (n=75, 48.7%); CIN 1 (n=67, 43.5%); and normal/benign findings (n=6,3.9%). 31.8% of LEEP specimens were removed in more than one fragment. The mean specimen volume was 2.9 cm3 (range 0.2-15.0). LEEP margin status was available for 130 patients. Positive margins (ectocervical/endocervical only, or both) were noted in 76 (58.5%) patients and associated with HIV+status (p=0.0499) and a diagnosis of CIN 2 or worse (p=0.0197). There were no associations between margin status and age, number of fragments or specimen volume.
Conclusion: Our results showed a high number of LEEP specimens with positive margins. Additional evaluation is needed to better understand the characteristics of precancerous cervical lesions in this high-risk population. As cervical cancer screening programs are scaled in Mozambique and other lower-resource countries, there is a need to train providers to perform high-quality LEEP and for accurate and timely pathological interpretation.
期刊介绍：
The International Journal of Gynecological Cancer, the official journal of the International Gynecologic Cancer Society and the European Society of Gynaecological Oncology, is the primary educational and informational publication for topics relevant to detection, prevention, diagnosis, and treatment of gynecologic malignancies. IJGC emphasizes a multidisciplinary approach, and includes original research, reviews, and video articles. The audience consists of gynecologists, medical oncologists, radiation oncologists, radiologists, pathologists, and research scientists with a special interest in gynecological oncology.
