The research study is titled " Carcinoembryonic Antigen Market - Key Facts and Forecast Predictions Presented Until 2023" which encloses important data about the production, consumption, revenue and market share, merged with information related to the market scope and product overview.
Cases have been correlated with serum tumour marker CEA (Carcinoembryonic antigen) also.
Immunohistochemistry (IHC) reveals expression of vimentin, but not cytokeratins, epithelial membrane antigen, carcinoembryonic antigen, desmin, [alpha]-fetoprotein, [[alpha].sub.1]-antitrypsin, type 4 collagen, caldesmon, S100, Melan-A, synaptophysin, chromogranin, CD99, estrogen receptor, androgen receptor, or testosterone.

But their roles in the disease pathogenesis are still unclear.3,9 In immunohistochemistry (IHC) low molecular weight keratin (LMWK), epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA), gross cystic disease fluid protein 15 (GCDFP-15), CD15 (Leu MI) are positive, also myoepithelial cells in S100 and smooth muscle actin (SMA) are positive.4,10 Clinical differential diagnosis includes Bartholin's duct cyst or abscess, epidermal inclusion cyst, mucous cyst, fibroma, lipoma, leiomyoma, endometriosis, amelanotic melanoma and squamous cell carcinoma.1,3,4,11
The more frequent incidence in girls, clear occurrence after puberty, positivity for sex hormone receptors, estrogen receptor (ER) and progesterone receptor (PR), and positivity and negativity for carcinoembryonic antigen (CEA) on immunohistochemical staining support the mullerian heterotrophy theory [6].
The discovery of the carcinoembryonic antigen (CEA) as a tumor marker for colorectal carcinoma in 1965 by Gold and Freedman [1] was the milestone for identifying a much wider family of 12 carcinoembryonic antigen-related cell adhesion molecules (CEACAMs) which mediate intricate mechanisms of modulation and dysregulation during complex biological processes regarding cancer progression, inflammation, metastasis, and angiogenesis [2].
Several antigens, such as carcinoembryonic antigen and mesothelin, have been chosen as the target of the engineered T-cells.
In contrast, carcinoembryonic antigen has been used as a biomarker of prognosis and therapeutic efficacy in non-small cell lung cancer.
Carcinoembryonic antigen (CEA, also known as CEA-CAM5 or CD66e) was discovered in malignant tumors of endodermally derived epithelium of the gastrointestinal tract and pancreas [7].
Tumor markers, such as matrix metalloproteinase proteins (MMPs) and carcinoembryonic antigen (CEA), reflect tumor biology and have the potential to solve a variety of clinical needs.
