MRC1 and metastatic malignant neoplasm in the lymph nodes: Among our patients, the prevalence of d-MMR was found to be substantially higher than average, probably due to the low sample size and missing data like lymph node metastasis status in patient records due to malpractice, thus a larger study might be warranted to give an accurate understanding of the prognostic and treatment implications of MMR-deficient EC and to assist in the formation of definitive management guidelines, additional investigations, including trials with planned designs, are required.
