Prognositc Significance of Microcystic Elongated and Fragmanted (MELF) Myometrial Invasion Pattern: A Retrospective Study
Objective: Endometrioid endometrial carcinomas (EEC) are the most commonly diagnosed malignancies of the female genital tract. Myometrial invasion depth is one of the most significant pathological prognostic parameters. Different morphological invasion patterns have been characterized. This study aimed to investigate the prognostic significance of the microcystic elongated and fragmented (MELF) myometrium invasion pattern in patients with EEC and its relationship with other clinicopathological parameters.
Methods: This study included 101 patients with EEC in our institution between 2011 and 2020. The MELF pattern was evaluated in hematoxylin-eosin-stained sections. Pan-cytokeratin staining was performed on paraffin-embedded blocks of lymph nodes for cases without lymph node metastasis.
Results: The MELF pattern was observed in 29 (29.8%) patients. It was significantly associated with lymphovascular invasion (p<0.001), pathologic stage (p=0.048), infiltrative pattern (p<0.001), and necrosis (p=0.005). No significant correlation was observed between the MELF pattern and overall and disease-free survival rates.
Conclusions: The MELF pattern is associated with other prognostic parameters, but its prognostic significance for survival has not been found. If the MELF pattern is observed in the hysterectomy material for cases without lymph node dissection during the first surgery, these patients may need additional surgery or adjuvant therapy due to the high risk of lymphovascular invasion and lymph node metastasis.
期刊介绍：
The Medeniyet Medical Journal (Medeniyet Med J) is an open access, peer-reviewed, and scientific journal of Istanbul Medeniyet University Faculty of Medicine on various academic disciplines in medicine, which is published in English four times a year, in March, June, September, and December by a group of academics. Medeniyet Medical Journal is the continuation of Göztepe Medical Journal (ISSN: 1300-526X) which was started publishing in 1985. It changed the name as Medeniyet Medical Journal in 2015. Submission and publication are free of charge. No fees are asked from the authors for evaluation or publication process. All published articles are available online in the journal website (www.medeniyetmedicaljournal.org) without any fee. The journal publishes intradisciplinary or interdisciplinary clinical, experimental, and basic researches as well as original case reports, reviews, invited reviews, or letters to the editor, Being published since 1985, the Medeniyet Med J recognizes that the best science should lead to better lives based on the fact that the medicine should serve to the needs of society, and knowledge should transform society. The journal aims to address current issues at both national and international levels, start debates, and exert an influence on decision-makers all over the world by integrating science in everyday life. Medeniyet Med J is committed to serve the public and influence people’s lives in a positive way by making science widely accessible. Believing that the only goal is improving lives, and research has an impact on people’s lives, we select the best research papers in line with this goal.
