ARAndrogen receptor (AR) is responsible for the regulation of the growth of the prostate epithelial cells. In untreated prostate carcinoma, AR positive cells are more likely to be responsive to hormonal therapy. In patients with hormone refractory prostate carcinoma, the presence of AR has a negative prognostic impact. It is also commonly expressed in salivary duct carcinoma. Immunohistochemistry (IHC)
BerEP4Ber-EP4 recognizes two glycoproteins of 34 and 49 kDa present on the surface and the cytoplasm of all epithelial cells except the superficial layers of squamous epithelial, hepatocytes and parietal cells. It does not label mesothelial cells and rarely marks mesotheliomas. It shows a broad spectrum of reactivity with human epithelial cells including simple epithelia and basal layers of stratified non-keratinized squamous epithelium and epidermis. Ber-EP4 reportedly distinguishes adenocarcinomas from pleural mesotheliomas. Immunohistochemistry (IHC)
BG8This antibody is specific for the Lewis Y (Type 2 Chain) carbohydrate antigen. Lewis Y has been evaluated as a clinical marker for the diagnosis and prognosis of cholangiocarcinoma, hepatocellular carcinoma and breast cancer. It was also shown that BG8 reacts predominantly with lung adenocarcinomas and is negative focally or weakly positive in epithelial mesotheliomas. Immunohistochemistry (IHC)
CAM 5.2Anti-Cytokeratin (CAM 5.2) has a primary reactivity with human keratin proteins that correspond to Moll`s peptides #7 and #8, Mr 48 and 52 Kd. Cytokeratin 8 is present on secretory epithelia of normal human tissue but not on stratified squamous epithelium. CAM 5.2 stains most epithelial derived tissue, including liver, renal tubular epithelium, hepatocellular and renal cell carcinomas. CAM 5.2 may not react with some squamous cell carcinomas. Immunohistochemistry (IHC)
CD10CD10, also known as Common Acute Lymphocytic Leukemia Antigen (CALLA), is expressed in early lymphoid progenitors and normal germinal center cells. It is almost always present on the surface of precursor B-lymphoblastic and Burkitt lymphomas and much less frequently on precursor T-lymphoblastic leukemia-lymphoma. Many follicular lymphoma and some diffuse large B-cell lymphomas, along with multiple myeloma are positive. CD10 is also present on breast myoepithelial cells, bile canaliculi, fibroblasts and with especially high expression on the brush border of kidney and gut epithelial cells. CD10 is also a good marker of endometrial stomal sarcoma. Immunohistochemistry (IHC)
CD31CD31 is a 130kDa transmembrane glycoprotein that is shared by vascular lining cells, megakaryocytes and platelets. This marker is highly restricted to endothelial neoplasms among all tumors of the soft tissue and its sensitivity is excellent. 100% of angiosarcomas and hemangiomas are CD31 positive. However, Kaposi’s sarcoma (KS) is labeled more consistently by CD34 than by CD31. CD31 has also been used as a prognostic marker measuring tumor angiogenesis. CD31 also stains histiocytes. Immunohistochemistry (IHC)
CD68CD68 is an antibody directed against lysosomes. It is important for identifying macrophages in tissue sections. It stains macrophages in a wide variety of human tissues, including Kupffer cells and macrophages in the red pulp of the spleen, lamina propria of the gut, lung alveoli, and bone marrow. This antibody reacts with myeloid precursors and peripheral blood granulocytes. It shows strong granular cytoplasmic staining of chronic and acute myeloid leukemia and also reacts with true histiocytic neoplasia. It also stains granular cell tumors and some cases of melanoma, renal cell carcinoma, and pleomorphic sarcoma. Tumors of lymphoid origin are usually not stained. Immunohistochemistry (IHC)
CEA (Mono)Carcinoembryonic antigen (CEA) is usually demonstrated as a linear labeling of the apical poles of cells lining the glandular lumen and occasionally as weak staining near the apex of normal colonic epithelial cells. Tumors tend to display an increased cytoplasmic staining. In specific cases, CEA can be useful in tumor diagnosis. Pancreatic carcinomas, testicular tumors, gallbladder neoplasms and granular cell myoblastomas all stain positive for CEA, while malignant tumors of brain, prostate, skin, lymphoreticular tissues, hepatocellular carcinomas, esophageal squamous cell carcinomas and mesothelioma fail to stain for CEA. Immunohistochemistry (IHC)
CK AE1/AE3Monoclonal antibodies AE1 and AE3 recognize the acidic and basic subfamilies of cytokeratin, respectively, thus the combination of these two antibodies can be used to detect almost all human epithelia. In surgical pathology, it is an important marker for carcinoma as well as some special tumor types which have an epithelial component or differentiation. This cocktail has been used to differentiate epithelial from non-epithelial tumors. Immunohistochemistry (IHC)
CK HMW (CK903/34BE12)CK903 (34betaE12) is a high molecular weight cytokeratin present in all squamous epithelium and their carcinomas. This antibody recognizes cytokeratins 1, 5, 10 and 14 that are found in complex epithelia. There has been no reactivity with cells derived from simple epithelia, mesenchymal tumors, lymphomas, melanomas, neural tumors and neuroendocrine tumors. One useful application is the identification of the basal cell layer in prostate tissue in the determination of carcinoma. Immunohistochemistry (IHC)
CK20Cytokeratin 20 (CK20) positivity is seen in the majority of adenocarcinomas of the colon, mucinous ovarian carcinomas, transitional cell, and Merkel cell carcinomas, and frequently in adenocarcinomas of the stomach, bile system and pancreas. CK7/CK20 immunostaining patterns may be helpful in separating pulmonary from colonic adenocarcinomas. Immunohistochemistry (IHC)
CK5/6D5/16 B4 clone of CK5/6 antibody reacts strongly with cytokeratins 5 and 6. Cytokeratin 5/6 have been found valuable for the distinction between low differentiated squamous cell carcinoma and adenocarcinoma. It labels mesothelioma, and epithelial basal cells in prostate and tonsil. No reactivity with other mesodermally derived tissues, such as muscle and connective tissues, has been observed. Anti-CK 5/6 has also been found useful in the differential diagnosis of atypical proliferations of the breast. Immunohistochemistry (IHC)
CK7Cytokeratin 7 (CK7) antibody reacts with proteins that are found in most ductal, glandular and transitional epithelium of the urinary tract and bile duct epithelial cells. CK7 distinguishes between lung and breast epithelium that stain positive, and colon and prostate epithelial cells that are negative. It also reacts with many benign and malignant epithelial lesions, e.g. adenocarcinomas of the ovary, breast and lung. Transitional cell carcinomas are positive and most prostate cancers are negative. This antibody does not recognize other intermediate filament proteins. Immunohistochemistry (IHC)
cMETThe cMET tyrosine kinase receptor, normally expressed by epithelial cells, is overexpressed and amplified in a variety of human tumors, including non-small cell lung carcinoma (NSCLC). High levels of intratumor cMET expression have been associated with a more aggressive biology and a worse prognosis in NSCLC. Engelman et al. reported that cMET amplification induced resistance to gefitinib in a gefitinib-sensitive lung cancer cell line. Moreover, cMET inhibition with a cMET tyrosine kinase inhibitor (PHA-665,752) restored gefitinib sensitivity. Immunohistochemistry (IHC)
CMV

In situ hybridization for detection of cytomegalovirus (CMV) RNA.

In Situ Hybridization (ISH)
COX2Cyclooxygenase-2 (COX-2) plays a role in tumorigenesis through stimulating epithelial cell proliferation, inhibiting apoptosis, stimulating angiogenesis, enhancing cell invasiveness, mediating immune suppression, and by increasing the production of mutagens. COX-2 is expressed in breast cancer, transitional cell carcinoma of the bladder, high-grade endometrioid carcinoma, and ovarian cancer. Overexpression of COX-2 is associated with poor prognosis in cervical cancers after radiation and concurrent chemotherapy. Immunohistochemistry (IHC)
DesminDesmin is an intermediate filament protein of both smooth and striated muscles. Antibody to desmin reacts with striated (skeletal and cardiac) as well as smooth muscle cells. Anti-desmin antibody is useful in identification of tumors of myogenic origin. It reacts with leiomyosarcomas (smooth muscle) as well as rhabdomyosarcomas (striated muscle). Immunohistochemistry (IHC)

EGFR Mutation Analysis

Bi-directional sequencing of exons 18-21 of the EGFR gene for detection of EGFR-activating mutations and TKI resistance mutations (including T790M) in these exons. Tumor enrichment is performed before extraction. Testing is approved for specimens from the state of New York.

Molecular
EMAEpithelial Membrane Antigen (EMA) antibody stains normal and neoplastic cells from various tissues, including mammary epithelium, sweat glands and squamous epithelium. Hepatocellular carcinoma, adrenal carcinoma and embryonal carcinomas are consistently EMA negative, therefore, keratin positivity with negative EMA favors one of these tumors. EMA is frequently positive in meningioma, which can be useful when distinguishing it from other intracranial neoplasms, e.g. Schwannomas. The absence of EMA can also be of value since negative EMA is characteristic of tumors such as adrenal carcinoma, seminomas, paraganglioma and hepatoma. Immunohistochemistry (IHC)
EREstrogen Receptor (ER) belongs to a superfamily of nuclear hormone receptors and is expressed in about 85% of invasive breast cancers. There are two known isoforms of estrogen receptor, ERα and ERß. It is a weak prognostic factor but a strong predictive factor for response to endocrine therapies, both in adjuvant and metastatic settings. The primary indication to assess ER in breast cancer is to predict response to hormonal therapies such as tamoxifen, other selective estrogen receptor modulators (SERMs) and aromatase inhibitors. In univariate analysis, moderate to strong staining in even 1% of the invasive tumor cells is associated with significant improvement in disease-free survival compared to those patients whose tumor lacks ER expression. Immunohistochemistry (IHC)
Ki67

Ki67 is a nuclear protein that is expressed in proliferating cells. Ki67 is preferentially expressed during late G1, S, M, and G2 phases of the cell cycle, while cells in the G0 (quiescent) phase are negative for this protein. Increased proliferative activity is associated with more aggressive tumor and decreased disease-free survival period.

Immunohistochemistry (IHC)

MLH1 Promoter Methylation Analysis

This assay is performed on tumor tissue to detect hypermethylation of the MLH1 gene promoter. Bisulfite modification of tumor DNA and real-time PCR are used to quantify CpG methylation within the promoter. Percentage of methylated DNA (compared to total DNA) is reported for positive results. Analysis should be considered in combination with IHC, BRAF, and/or MSI.

Molecular
MMR Panel by IHC (MLH1, MSH2, MSH6, PMS2)

A well-defined subtype of colorectal cancer (CRC) is characterized by deficiencies in the mismatch repair (MMR) pathway. MMR status may impact prognosis and benefit of adjuvant chemotherapy. MLH1, MSH2, MSH6, and PMS2 protein expression (as assessed by IHC) and microsatellite instability analysis (MSI) assessed by PCR are well-established tools to screen for Lynch syndrome (LS), and such testing is recommended for all new colorectal cancer diagnoses. MMR IHC and molecular MSI testing also serve as companion diagnostic tests in a wide range of solid tumors for selection of certain immuno-oncology therapies.

Immunohistochemistry (IHC)
MSAMuscle Specific Actin (MSA) antibody recognizes the alpha and gamma isotypes of skeletal, cardiac, and smooth muscle cells. It is non-reactive with other mesenchymal cells and all epithelial cells except for myoepithelium. This antibody is useful in the identification of tumors with muscle differentiation and detection of myoepithelial cells. Immunohistochemistry (IHC)
MUC1

Mucin 1 (MUC1) is a high molecular weight glycoprotein that is found on the apical surface of many glandular epithelia, including the gastrointestinal, respiratory, urinary, reproductive tracts and some hematopoietic cell lineages. MUC1 has been implicated in progression of numerous types of cancer, including breast, colon, lung, gastric and pancreatic cancers. MUC1 expression in tumors is greatly increased and accompanied by altered aberrant expression patterns that become more diffuse when compared to the normal apically restricted pattern.

Immunohistochemistry (IHC)
MucicarmineSpecial stain. Mucicarmine staining is used to identify epithelial mucins, namely acid mucopolysaccharides. Staining is useful to distinguishing mucin negative undifferentiated squamous cell lesions from mucin positive adenocarcinomas. In addition, this product will stain the mucopolysaccharide capsule of Cryptococcus neoformans. Immunohistochemistry (IHC)

p21p21 is a cyclin dependent protein kinase inhibitor and is a member of a family of proteins that functions to slow down cell division. p21 is found in t cells as they transitions from G1 phase to S phase. Low nuclear expression of p21 has been associated with poor prognosis in colon and prostate carcinomas. Immunohistochemistry (IHC)
p27p27 (KIP1) belongs to the family of cell cycle regulators that cause cell cycle arrest in G1 phase. p27 promotes apoptosis, plays a role in terminal differentiation of some tissues and mediates chemosensitivity in solid tumors. Decreased p27 KIP1 expression in tumors is associated with a more aggressive tumor phenotype such as poor histologic grade, presence of lymphovascular invasion and higher growth fraction. These findings have been validated on various cancers such as breast, colon, esophagus, stomach, lung and prostate. Immunohistochemistry (IHC)
p53The product of the p53 gene is a nuclear phosphoprotein that regulates cell proliferation. Excess accumulation of the mutant p53 gene product results in inactivation of its tumor suppressor function and cellular transformation. Overexpression of mutant p53 gene has also been associated with high proliferative rates and poor prognosis in breast, colon, lung, and brain cancer, as well as in some leukemias and lymphomas. Immunohistochemistry (IHC)
PAX8The PAX8 gene is a member of the paired box (PAX) family of transcription factors. This family plays critical roles during fetal development and cancer growth. PAX8 is involved in kidney cell differentiation, and thyroid development. PAX8 has been shown to be expressed in three of the most common types of renal cell carcinoma including clear cell, chromophobe and papillary carcinoma. PAX8 stains nuclei exclusively and performs well in formalin-fixed paraffin-embedded (FFPE) tissues. PAX8 has been shown to be positive in thyroid and ovarian carcinomas. Immunohistochemistry (IHC)
PgR

Progesterone Receptor (PR) belongs to a superfamily of nuclear hormone receptors. Estrogen Receptor (ER) induces PR expression, therefore, PR status serves as an indicator of an intact ER pathway. There are two known isoforms of PR; PR? and PRß. The current assays in clinical breast cancer measure both isoforms. PR is expressed in about 60-70% of invasive breast cancers. It is a weak prognostic factor by itself but a modest predictive factor that adds to the predictive value of ER for response to endocrine therapies, both in adjuvant and metastatic settings. The primary indication to assess PR in breast cancer is to predict response to hormonal therapies, such as tamoxifen, other selective estrogen receptor modulators (SERMs) and aromatase inhibitors.

Immunohistochemistry (IHC)
pHistone H3 (PHH3)Phosphohistone H3 (PHH3) is a marker of cells in the late G2-M phase of the cell cycle. It is not expressed in apoptotic cells which may be confused with mitotic figures on a routine H&E stained slide. PHH3 can be used as a surrogate of mitotic activity or as an independent prognostic marker in breast carcinomas. Immunohistochemistry (IHC)
PIK3CA Mutation Analysis

Bi-directional sequencing of PIK3CA exons 1, 9, and 20 which are the most commonly-mutated regions of the gene.

Molecular
PMS2PMS2, also known as PMS1 protein homologue 2, is a DNA mismatch repair (MMR) protein. The PMS2 protein forms a heterodimer with the MLH1 protein which is then activated in the presence of ATP; this complex coordinates the binding of other proteins that repair DNA errors arising during cell preparation for cell division.
The loss of PMS2 expression in tumors can be helpful in identifying hMLH1 mutation carriers. PMS2 gene defects account for a small but significant proportion of colorectal cancers and for a substantial proportion of tumors with microsatellite instability.

Tumor Mutation Burden

Tumor Mutation Burden (TMB) testing at NeoGenomics measures the number of non-synonymous DNA coding sequence changes per megabase of sequenced DNA. Testing is performed routinely within the NeoTYPE™ Discovery Profile, can be added to any of the NeoTYPE Solid Tumor Profiles, and is available as a stand-alone test. Results are reported as low, high intermediate, and high upper quartile in reference to the median genomic TMB value determined across a wide variety of tumor types in an internal validation study. TMB is also called tumor mutational burden or tumor mutation load (TML).
