A systematic review and meta-analysis’  \nLiming Zhou, MB* , Mai Li, MM, Jie Li, MM  \nEndometrial cancer (EC) is the sixth most detected cancer and the 14th most prevalent cause of cancer death in women globally, affecting 2 . 8% of women at some point in their lifetime[1] . Patients typically present with uterine-confined pathology and have high survival rates. The key predictors of cancer outcome are histological character, tumor grade and size, age, degree of myometrial invasion, lymph node involvement, and disease stage.  \nOne of the most prevalent pathological signs in hysterectomy tissues is known as adenomyosis, which spreads from the endometrium into the uterus, the myometrium, and the endometrial glands. With a varying prevalence of 12–66%[2], it is one of the most common ancillary histopathological results of EC, especially of the endometrioid histotype. Numerous studies have investigated whether adenomyosis is present in EC patients. Those who investigated the importance of adenomyosis in endometrial adenocarcinoma suggested that it had negative impacts on EC. However, in other studies, adenomyosis with EC has been linked to early-stage malignancy and extended surveillance. Furthermore, subsequent investigations have demonstrated that adenomyosis does not negatively affect the prognosis and questionnaires of EC patients. It is therefore still unclear whether EC and adenomyosis are related.  \nSun et al. [3] performed a systematic review and meta-analysis to explore the impact of lymphadenectomy on the prognosis of EC arising in adenomyosis (EC-AIA) . The results of the study indicated that for patients who are unexpectedly diagnosed with EC-AIA following hysterectomy for benign tumors, a second surgery of supplementary lymphadenectomy may be a better option.  \nKoshiyama et al. [4] reported only four cases in 564 patients (0.74%) operated between 1981 and 2001 .

Due to the absence of an anatomic set in the basal part of endometrial tissue, cancer first develops within the myometrial part and smoothly spreads to the myometrial stromal layer. Cancer that has directly invaded themyometrial stromal tissue extends rapidly to the lymphatic and circulatory systems. However, many molecular elements of the malignant development of adenomyosis remain unknown. The relationship between adenomyosis and the disruption of heterozygosity in the DNA mismatch repair gene has only been briefly described in research[5] .  \nThe present research has some drawbacks. First, there is adeficiency of pathological evaluation to differentiate between ECs with adenomyosis and ECs developing from a","cbCais1asYUwkyZw","https://ap.wps.com/l/cbCais1asYUwkyZw","pdf",197224,"English","# Background and clinical context\n# Adenomyosis and its relationship to EC\n# Prior studies on lymphadenectomy and EC-AIA\n# Pathogenesis hypotheses and molecular considerations\n# Limitations and implications for future research","[{\"question\":\"What is EC-AIA and why is it clinically important?\",\"answer\":\"EC-AIA refers to endometrial cancer arising in adenomyosis.
