(Next Generation Sequencing)
Endometrial cancer is the most common malignant tumor of the female reproductive system in developed countries.
Factors related to endometrial cancer:
1. Obesity> 23kg of normal weight, the risk increases by 10 times;
2. Women who have not given birth and infertility;
3. Patients with functional ovarian tumors (granulocytoma);
4. Long-term use of females hormones;
5. Genetic factors, family history of colon cancer (lynch syndrome).
In 2013, the Tumor Gene Atlas Research Network (TCGA) studied 373 cases of endometrial cancer, using genomics, transcriptomics and proteomics methods to analyze mutation lineage, microsatellite instability (MSI), somatic cell copy Number changes (SCNAs), etc., TCGA proposes to divide endometrial cancer into four categories:
(1) POLE ultramutated.(2) microsatellite instability hypermutated (MSI-H）.(3) copy number low (CN-L) .(4) copy number high (CN-H).

NCCN recommends molecular classification detection
This test uses high-throughput sequencing method to detect 11 genes related to molecular classification of endometrial cancer, including POLE, TP53, MLH1, MSH2, PMS2, MSH6, as well as MSI related sites.
SIGNIFICANCE OF MOLECULAR CLASSIFICATION
For operation stage I~II, follow-up can be considered after the operation,
adjuvant treatment is not required.
The prognosis is moderate, it is sensitive to the treatment of immunocheckpoint inhibitors, but the current evidence is limited to advanced and recurrent cases.
Suggest for the screening of Lynch syndrome.
Copy Number Low
The prognosis is moderate, which is more sensitive to hormone therapy (PR+),
and the effect of childcare for young patients is better.
Copy Number High
The prognosis is the worst, which requires active adjuvant treatment and may be sensitive to chemotherapy.
