Summary
Endometrial carcinoma, a common female cancer, presents two subtypes with distinct genetic alterations. Understanding these genetic changes is key to understanding endometrial carcinogenesis.
Area of Science:
- Gynecologic Oncology
- Cancer Genetics
- Molecular Pathology
Background:
- Endometrial carcinoma is the most common female genital tract malignancy in Western countries.
- It ranks as the fourth most common cancer in women globally.
- Two main subtypes exist: estrogen-related (Type I) and non-estrogen-related (Type II).
Purpose of the Study:
- To review the genetic alterations in endometrial carcinogenesis.
- To correlate genetic changes with the morphological features of endometrial tumors and their precursors.
- To differentiate genetic profiles between Type I and Type II endometrial carcinomas.
Main Methods:
- Review of existing literature on endometrial cancer genetics and morphology.
- Analysis of genetic alterations including microsatellite instability, PTEN, PIK3CA, K-Ras, CTNNB1, p53 mutations, and chromosomal instability.
- Correlation of genetic findings with clinicopathological subtypes.
Main Results:
- Type I (endometrioid) endometrial carcinoma is associated with microsatellite instability and mutations in PTEN, PIK3CA, K-Ras, and CTNNB1.
- Type II (non-endometrioid) endometrial carcinoma is characterized by p53 mutations and chromosomal instability.
- Distinct genetic profiles parallel the clinicopathological differences between the two subtypes.
Conclusions:
- Genetic alterations play a crucial role in the development of endometrial carcinoma.
- Understanding the specific genetic pathways for Type I and Type II tumors is essential for targeted therapies.
- Morphological features correlate with underlying genetic changes in endometrial carcinogenesis.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

01:12Loss of Tumor Suppressor Gene Functions
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
