Inadvertent cervical cancer: a narrative review.

Abstract

Inadvertent cervical cancer, defined as infiltrative cervical carcinoma diagnosed after a simple hysterectomy for presumed benign disease, remains clinically significant yet understudied. Despite the potential for eradication of cervical carcinoma through vaccination, screening, and early treatment, disparities in health care access continue to result in preventable cases, some of which are identified only postoperatively. This condition has long been recognized, yet its management remains undefined and is supported primarily by low- or very low-quality evidence. Diagnostic failures often stem from inadequate preoperative evaluation, missed follow-up of abnormal screening results, and insufficient re-excision with conization when indicated. Social determinants of health, including race and ethnicity, socioeconomic status, and insurance status, contribute significantly to these lapses. The identification of invasive disease only postoperatively may negatively impact prognosis, even in early stages. Treatment strategies for inadvertent cervical cancer include observation, radiotherapy with or without chemotherapy, and completion surgery, such as lymph node assessment with or without parametrectomy. While retrospective studies suggest similar oncologic outcomes across some strategies (eg, additional surgery or radiotherapy), the absence of prospective trials limits definitive conclusions. Furthermore, morbidity and quality-of-life outcomes are frequently underreported. To support clinical decision-making, we propose a risk-based classification of this condition, categorizing patients as very low, low, medium, or high risk. Until stronger evidence emerges, treatment decisions should be individualized based on tumor features, surgical approach, and patient preferences. This review summarizes current evidence, highlights gaps in knowledge, and offers a pragmatic algorithm for managing this complex clinical entity.
