AntiCK 56 has also been found useful in the differential diagnosis of atypical proliferations of the breast The presence of distinct population of CK 56 negative cells supports a diagnosis of ADH, whereas mosaic pattern of CK56 expression favors UDH Preparation for CK5/6 Test Most blood tests do not require any special kind of preparation Cytokeratin 5/6 staining is usually weak or negative for sarcomatoid mesothelioma, the least common and hardesttotreat cell type of the asbestosrelated cancer The marker is also not effective in telling the difference between pleural mesothelioma and squamous cell carcinomasMalignant mesothelioma diagnosis is a panel of two positive and two negative immunohistochemical markers 1 Immunohistochemical staining for Cytokeratin (Pancytokeratin, cat #PDM071) is used for the diagnosis of epithelioid mesothelioma Cytokeratin can be used to highlight stromal invasion of malignant cells 2 Cytokeratin 5/6 (CK 5/6, cat

What is ck 5/6-CK7 / CK in carcinomas of adrenal cortex and prostate ( Mod Pathol 00; ) To distinguish primary lung carcinoma (CK7 / CK) from metastatic colonic carcinoma to lung (CK7 / CK, BMC Cancer 06;631) To help distinguish colon carcinoma (80% are CK) and poorly differentiated prostatic carcinoma (90% are CK) at biopsy Immunohistochemically, the tumor was positive for p63, various types of cytokeratin, CK 5/6, suggesting that the carcinoma had squamous differentiation 911 Negative immunoreactions for TTF1 and PE10 suggest that the tumor had no adenocarcinomatous differentiation 911 The absence of neuroendocrine antigens (chromogranin, synaptophysin

Primary lung adenocarcinomas expressed TTF1 in 90% and napsin A in 84% of the cases, whereas 10% were positive for p63, 7% for CDX2, 2% for CK, and 2% for GATA3 Only 68% of the lung adenocarcinomas were positive for CK7, TTF1, and napsin A and negative for all other markersPRODUCT SPECIFICATIONS Tissue Positive staining tonsil and negative staining liver Fixation Formalin 10%, Phosphate Buffered () Section/Glass Paraffin sections cut at 4 microns on Superfrost™ Plus slides Quality Control Stain Cytokeratin 5/6 (CK5/6) quality control stained slide(s) included Reactivity Guaranteed product specific reactivity for one year from date of By contrast, a negative correlation was observed between CK and CK5/6 In cases with both CK and CK5/6 reactivity, the staining patterns of these two markers were generally reciprocal Although they were not completely mutuallyexclusive, CK tended to be stained on CK5/6negative tumor cells and vice versa

 Cytokeratin 5/6 (CK5/6) is an intermediate filament of the group of highmolecularweight cytokeratins and is consistently expressed in stratified epithelia and derived neoplasm such as squamous carcinoma Furthermore, CK5/6 is expressed in the basalmyoepithelial layer of prostate, breast, and salivary glands ,An association with ERα expression could not be detected but the combination of cytokeratin 5/6 IRS = 12 and ERα negativity resulted in a significant negative prognostic marker (overall survival P = 003 and progressionfree survival P < 0001) We substantiate cytokeratin 5/6 protein expression as a frequent feature of highgrade serousFor CK5 staining 96% of ADH/DCIS cases were negative or focally positive, whereas all 32 UDH cases had diffuse staining The combination of ER and CK5 increased the sensitivity (94% to 97%) For PR staining 11 of 23 ADH cases (48%), 6 of 10 DCIS cases (60%), and 4 of 32 UDH cases (13%) showed diffuse staining l2 staining showed no

Breast cancer cells taken out during a biopsy or surgery will be tested to see if they have certain proteins that are estrogen or progesterone receptors When the hormones estrogen and progesterone attach to these receptors, they fuel the cancer growth Cancers are called hormone receptorpositive or hormone receptornegative based on whether or not they have these All cases were Ecadherin negative CK5/6 was positive in 14 (17%) of cases and was entirely negative in the remaining 68 cases (%) In 8 of the 14 CK5/6 cases, staining was diffuse and intense In the remaining 6 cases, staining was patchy (>1 lowpower field between positive areas) but still of high intensity p63 and cytokeratin (CK) 5/6 are both considered to be markers of basal and squamous cell differentiation in several normal epithelia and human tumors 1, 2 Previous studies have indicated that p63 is important for epithelial proliferation and differentiation, 2 and studies using knockout mice have suggested that p63 plays a key role in maintaining progenitor cell

Most p63expressing tumors diffusely and strongly express CK18 at levels similar to benign luminal cells (case 1 and 3), although some show weaker diffuse expression (case 2) Similarly, most are entirely negative for CK5/6 (cases 2 and 3), although a minority weakly and focally express CK5/6 (case 1) All images are at 0 × magnification For CK5/6, 94% of FEA, ADH, DCIS, and LCIS revealed negative stainings, but all of the UDH demonstrated diffuse stainings For CK903, 90% of FEA, ADH, and DCIS were negative to focally positive, and all of the UDH and 90% of LCIS were diffusely positive Considered a marker of or associated with the basal phenotype (also CK 5/6, CK 14) of invasive or in situ ductal carcinoma of breast (Mod Pathol 06;) Sensitive marker of sentinel nodal metastases by RTPCR in oral squamous
