Expand Collapse Endometrial Cancer  - General Description Endometrial cancer begins in cells within the endometrium, the tissue that lines the inside of a woman's uterus. The uterus is the hollow muscular organ in which a baby (fetus) develops. The outer muscular layer of the uterus is called the myometrium. The lower end of the uterus is the cervix, which leads to the vagina. Cancer can develop in the cervix and vagina, but endometrial cancer is the most common cancer affecting a women's reproductive system. This year about 47,000 U.S. women will be diagnosed with endometrial cancer.

Most endometrial cancers are adenocarcinomas, which begin in gland-like cells that produce mucus and other fluids. Examination of the cancer tissue under a microscope can help differentiate the cancer type and roughly predict tumor behavior. When cancer cells are closer in appearance to normal endometrial tissue, it is classified as a well differentiated cancer and this usually indicates that the cancer will not spread. On the other hand, when the cancer cells are distinctly different from normal cells, they are considered poorly differentiated and are most likely to invade the myometrium. From the myometrium, the cancer can spread to lymph nodes in the pelvis and chest and to other parts of the body, such as the lungs, liver, bones, brain and vagina.

Endometrial cancer (and other tumors) can spread (metastasize) from the place where it started (the primary tumor) in 3 ways. First, it can invade the normal tissue surrounding it. Second, cancer cells can enter the lymph system and travel through lymph vessels to distant parts of the body. Third, the cancer cells can get into the bloodstream and go to other places in the body. In these distant places, the endometrial cancer cells cause secondary tumors to grow.

To find out whether the cancer has entered the lymph system, a surgeon removes all or part of a lymph node near the primary tumor and a pathologist looks at it through a microscope to see if cancer cells are present. Several kinds of imaging can also be performed to determine if endometrial cancer has spread. These include chest x-rays, MRI and CT scans.

Despite significant improvements in the treatment of endometrial cancer, novel therapies and treatment strategies are needed.

Cancer of the endometrium is the most common gynecologic malignancy and accounts for an estimated 47,000 newly diagnosed cases in the United States in 2012. Endometrial cancer encompasses a broad range of histologic subtypes, with the most common being the endometrioid endometrial adenocarcinoma. Marked differences in clinical behavior have been observed in patients with endometrial cancers depending on the histologic subtype, the tumor grade and the extent of cancer spread. A classification system that groups endometrial cancers into Type I and Type II has been proposed to account for the divide in clinical behavior.

Type I endometrial cancers account for approximately 75-85% of endometrial cancers and tend to be of endometrioid histology, are most commonly diagnosed at stage I/II or are confined to the uterus and cervix. These tumors can present with a precursor lesion known as atypical hyperplasia, and are associated with unopposed estrogen exposures such as obesity, hormone replacement or tamoxifen use. For these patients, surgery is likely to be a curative procedure and lymph node staging is generally not pursued unless risk factors are present. The addition of vaginal radiation has been shown to reduce recurrence of some early stage cancers if certain risk factors are present. Overall, the recurrence risk for these women is between 2-7%.

Type I cancers, type II endometrial cancers present with a spectrum of histologies including uterine papillary serous carcinoma (UPSC), carcinosarcoma, clear cell carcinoma and high-grade endometrioid carcinoma. These cancers are high-grade by definition, tend to present with disease outside of the uterus (stage III or IV) and have a high propensity to develop recurrence after primary therapy. Common sites of metastasis include pelvic/para-aortic lymph nodes, vagina, lungs, liver and peritoneum. The upfront therapeutic approach to type II cancers frequently involves individualized multi-modality combinations of aggressive cytoreductive surgery, followed by platinum containing chemotherapy and pelvic or abdominal radiation. While this subset of patients accounts for only 15-25% of patients with endometrial cancer, patients with these tumors account for 75% of the mortality observed.

In the recurrent setting, type I and II endometrial tumors tend to be managed in a similar fashion. When a localized recurrence occurs, surgery and focused radiation is commonly employed and is sometimes followed by platinum- and taxane-based cytotoxic chemotherapy. With widespread or surgically inaccessible recurrent disease, chemotherapies provide the mainstay of therapy. While low-grade advanced stage or recurrent tumors are commonly refractory to cytotoxic agents, they may (20-30%) respond to hormonal therapies that modulate the progesterone or estrogen receptor. As type II cancers are high-grade and commonly (40-50%) present with extra-uterine spread, the risk of recurrence is markedly elevated in this population and further therapeutic modalities in the upfront setting are often warranted.

Correlative scientific investigations have utilized the type I and II distinctions to describe molecular signatures specific to the individual tumors types that may be key drivers of the neoplasia. By targeting specific overactive pathways with novel small molecule tyrosine kinase inhibitors (TKI) or antibody therapies, investigators hope to improve the therapeutic options for patients with endometrial cancer. Type I cancers have been shown to have molecular alterations via gene mutation, gene amplification or protein expression in KRAS, CTNNB1 and PTEN. In contrast, type II cancers have been shown to have 20-30% gene amplification in the HER2 (ERBB2) gene and a close to 90% frequency of mutation in the TP53 gene. Alterations in the phosphoinositol 3-Kinase (PI3K) pathway appear to affect both type I and II endometrial cancers through alterations in PTEN (50-80%) and PIK3CA (25-40%). With many promising signatures, clinical trials are currently in development.

Expand Collapse ATR  - General Description
CLICK IMAGE FOR MORE INFORMATION
The protein encoded by ATR is a serine/threonine kinase and DNA damage sensor, activating cell cycle checkpoint signaling and causing a pause in the cell cycle following DNA replication stress or damage. The activated protein can phosphorylate and activate several important proteins that are involved in the inhibition of DNA replication and cell division, which are critical for DNA repair.

The maintenance of intact, correctly sequenced DNA is vital to the life of a cell. If there are mistakes made in replicating DNA before cell division, subsequent daughter cells will have inaccurate or damaged DNA, and may either die or carry mutations that can contribute to the development of cancer. For this reason, cells have evolved multiple pathways to repair mistakes in-or damage to- DNA. The specific repair pathway used by the cell depends on the type of DNA damage that has occurred. The types of DNA repair that we are focusing on relate directly to cancer. These involve a break in BOTH strands of DNA, which can be the result of ionizing radiation or other DNA damaging agents. This type of DNA damage is called Double Strand Breaks (DSB's). There are two main pathways used by cells to repair DSB's in their DNA, one is Homologous Recombination (HR), the other is Non-Homologous End Joining (NHEJ). This page of our website focuses on the HR pathway (there is a separate web page for NHEJ repair if you select PKcs from the gene list).

Many proteins are involved in the complex HR pathway to repair DSB's in DNA. There is a graphic above that depicts the HR pathway (if you click on the graphic, it will enlarge and become a bit easier to follow). While complicated, the DSB at the top right of the graphic is acted upon by a series of proteins in the circle of steps shown that ultimately lead to the complete and accurate repair of the DSB in the DNA.

Some of the proteins involved in the HR DSB repair pathway are MRE11, NBS1, RAD50. These three proteins make up the MRN complex. This complex detects DSB's in the DNA. Once the DSB is found by the MRN complex, the MRN complex functions with BRCA1 and CtIP to resect the DSB’s to form single stranded DNA “tails”. Meanwhile, DSB's also activate the ATM protein, which can act upon CHK2 to activate it, as well as directly activating the tumor suppressor TP53. TP53 can cause cell cycle delay, giving the cell time to repair DNA breaks or mistakes before the cell cycle leading to division resumes. In the next step, RPA binds to the single stranded DNA "tails" that have been created by BRCA1 and CtIP in conjunction with the MRN. The binding of RPA activates another protein called ATR. ATR has many important functions, including activating CHK1, which can cause cell cycle delay giving cells time to repair DNA. ATR also regulates BRCA1 which recruits a bound group of proteins including PALB2/BRCA2/RAD51. In the next step, RAD51 displaces the RPA that is on the single stranded DNA, with the involvement of BRCA2/PALB2 and RAD51c. BRCA1/BARD1 helps RAD51 coated single stranded DNA to invade double stranded DNA with homologous sequences to form a DNA repair loop. With the help of DNA polymerases, the repair loop creates the opportunity to use the intact homologous DNA as a template to correctly repair DSB’s. Enzymes called ligases reconnect the ends of the DNA, leading to complete and accurate repair of the DSB in DNA.

After studying familial cancer syndromes, germline or inherited BRCA1 and BRCA2 were identified a while ago as proteins that when altered by mutation, cause certain cancers. Some BRCA1 and BRCA2 genes become mutated somatically, meaning in a non-inherited way. When either gene is mutated, the resulting protein cannot perform its role in DNA repair correctly. This turns out to be true for other proteins in the HR pathway as well. Recently, scientists have found mutations in many of the other genes that encode the proteins involved in the HR pathway as well. Mutations in HR pathway members include MRE11, NBS1, RAD50, ATM, CHK2, BRCA1, PALB2, RAD51, BRCA2, BARD1, and RAD51c (these are depicted in red in the above graphic). This remarkable number of mutations highlights how important the HR DSB DNA repair pathway is in cells. The results of any of the mutations in HR pathway proteins results in proteins that do not function properly in their role in DNA repair. Without proper function of the proteins involved in DNA repair, DNA mistakes or breaks are not properly repaired, and the damaged DNA contributes to the development of cancer.

ATR is only rarely mutated in cancer, however, the frequent mutations in ATM result in cells that are completely reliant on the ATR pathway to repair DSB's in the DNA. This has therapeutic implications for treatment of tumors that have mutations in the HR DNA repair pathway.

Testing for mutations in the many genes/proteins involved in DNA repair discussed above is available in the MGH genetics lab. Treatment as well as clinical trials studying new drugs that target defects in these proteins-including ATR- are available at the MGH Cancer Center.

Mutations in the ATR gene are extremely rare in cancers. In fact, the ATR protein and its role in causing cell cycle delay through activating the protein CHK1 is a key pathway. Cell cycle delay induced by CHK1 gives the cell time to repair DSB's in the DNA, thereby acting as a tumor suppressor. When other proteins in the HR DNA pathway are mutated (see red proteins in the graphic above), ATR is the only option for DNA repair left to cells. This is why ATR inhibitors and other therapies can be effective treatments inducing death to tumor-cells.

Alterations in the gene encoding ATR are not found in endometrial cancers. ATR is an important protein in the DNA repair pathway. ATR controls a signaling pathway in the cell by activating CHK1, which causes a delay in the cell cycle (see graphic above). Without this delay, cells would not have time to repair broken or damaged DNA. The accumulation of damaged DNA in the cell can lead to cancer.

ATR has become an important protein to inhibit with drugs in cancer. Cancer cells often have genetic alterations in other proteins in the DNA repair pathway (see red proteins in graphic above). If the ATM protein is mutated and unable to cause cell cycle arrest for DNA repair, then ATR is the only option for cancer cells to use to delay the cell cycle and repair DNA. Drugs targeting ATR block this pathway, leaving cancer cells no way to pause the cell cycle to achieve DNA repair. The tumor cells die as the result of accumulated damaged or broken DNA.
