Endometrial cancer remains the most common gynecologic malignancy in the United States, with a majority being low-grade and an increasing incidence among young women. Early-stage, low-grade endometrial cancer generally has a favorable prognosis, and surgical treatment alone can often be curative. Young women should consider ovarian conservation to avoid the risks of surgical menopause.
In 2020, endometrial cancer continues to be the most common gynecologic malignancy in the United States. The majority of endometrial cancer is low grade, and nearly 1 of every 8 low-grade endometrial cancer diagnoses occurs in women younger than 50 years with early stage disease. The incidence of early-stage, low-grade endometrial cancer is increasing particularly among women in their 30s. Women with early-stage, low-grade endometrial cancer generally have a favorable prognosis, and hysterectomy-based surgical treatment alone can often be curative. In young women with endometrial cancer, consideration of ovarian conservation is especially relevant to avoid both the short-term and long-term sequelae of surgical menopause including menopausal symptoms, cardiovascular disease, metabolic disease, and osteoporosis. Although disadvantages of ovarian conservation include failure to remove ovarian micrometastasis (0.4%-0.8%), gross ovarian metastatic disease (4.2%), or synchronous ovarian cancer (3%-5%) at the time of surgery and the risk of future potential metachronous ovarian cancer (1.2%), ovarian conservation is not negatively associated with endometrial cancer-related or all cause mortality in young women with early-stage, low-grade endometrial cancer. Despite this, utilization of ovarian conservation for young women with early-stage, low-grade endometrial cancer remains modest with only a gradual increase in uptake in the United States. We propose a framework and strategic approach to identify young women with early-stage, low-grade endometrial cancer who may be candidates for ovarian conservation. This evidence-based schema consists of a 2-step assessment at both the preoperative and intraoperative stages that can be universally integrated into practice.
