Endometrial cancer occurs primarily in postmenopausal women older than 60 years of age. Especially in young patients with endometrial cancer, a positive family history with respect to cancer and/or development of synchronous or metachronous tumors can be indicative of hereditary factors. One genetic disorder, playing an important role in the development of endometrial cancer in young women, is hereditary non-polyposis colorectal cancer (HNPCC). The mean age to develop endometrial cancer because of a mutation in one of the HNPCC-genes is below 50 years. Mutation carriers have a life-time risk of about 50% for endometrial cancer. Especially young patients with endometrial cancer should always be asked for the family history and after primary treatment the family history should regularly be updated during follow-up.

Endometrial Cancer is the most frequent tumor in western world nations, with 142,000 new cases each year and 42,000 casualties. This form of cancer typically affects women between 55 and 65 years of age, and ranks fourth among female tumors. Endogenous predisposing conditions to endometrial cancer development are: late menopause, early menarche and hyperestrogenism, while hormone replacement therapy, obesity, alcohol, diabetes, and a diet rich in animal fats as well as chronic liver disease, are the exogenous factors. This tumor may also have an hereditary predisposition, as in the Lynch Syndrome or in HNPCC (Hereditary NonPolyposis Colorectal Cancer), since genetic modifications induced by the "MisMatch Repair" genes lead to a tumoral development susceptibility, not only in the colon. The phenotypical consequences of these genetic modifications may be found in the microsatellite instability (MSI) and in the loss of heterozygosity (LOH), which generate the replication errors in positive phenotypes repeats. These express the incapability to repair short nucleotide insertions or deletions, generated by a wrong DNA replication. Due to such genetic modifications, new allelic variants arise in the endometrial tissue, confirming the high degree of this genetic disorder. Recent studies showed that the MSI and LOH in endometrial cells may be associated with the possible loss in the expression of cellular control and with the possible degeneration of the cell growth phenomenon. There is also a possibility of utilizing these new genetic markers in the endometrial mucosa to study these tissues and to detect any possible neoplastic transformations, thanks to Genomics.

Lynch syndrome is the hereditary disorder that most frequently predisposes to colorectal cancer as well as predisposing to a number of extracolonic cancers, most prominently endometrial cancer. It is caused by germline mutations in the mismatch repair genes. Both its phenotype and genotype show marked heterogeneity. This review gives a historical overview of the syndrome, its heterogeneity, its genomic landscape, and its implications for complex diagnosis, genetic counseling and putative implications for immunotherapy.

Lynch syndrome is a genetic disorder related to cancer predisposition, including colorectal cancer, endometrial cancer, and ovarian cancer. Germline mutations in mismatch repair genes, including MLH1, MSH2, MSH6, and PMS2, are responsible for this condition. Cancer tissue specimens resected from small bowel adenocarcinoma in a Japanese patient showed decreased expression of MLH1 and PMS2 by immunohistochemistry testing. Finally, a novel MLH1 mutation, c.1833dup, was identified in this patient.

Lynch syndrome is a genetic condition defined by a germline mutation of an MMR (MisMatch Repair) gene leading to a defective DNA MMR system. Therefore, it is characterized by the predisposition to a spectrum of cancers, primarily colorectal cancer (CRC) and endometrial cancer (EC). Lynch syndrome-related CRC accounts for 3% of all CRC. Lynch syndrome also accounts for 2% of all EC. In case of Lynch syndrome, there is usually a familial history of cancer defined by the Amsterdam and Bethesda criteria. Diagnosis is made by tumor testing with (i) MMR immunohistochemistry and (ii) PCR for MSI (microsatellite instability), a genetic phenotype that characterizes these tumors. MSI can also be detected in sporadic tumors, through epigenetic events inactivating the MMR system. Progress in diagnosis and molecular biology has allowed for better identification of Lynch patients but also other rare genetic syndromes. MSI tumors can now benefit from new treatments such as immunotherapy which underlines the importance of their diagnosis. Finally, patients with Lynch syndrome as well as their relatives, undergo specific surveillance in order to prevent development of other cancers. This review will summarize the different aspects of Lynch syndrome and also focus on recent progress on the topic.
