For confirmation, immunohistochemistry for SATB2, a marker of osteoblastic differentiation, was carried out. SATB2 was diffusely immunopositive in the nuclei of tumor cells [Figure 2f]. A final diagnosis of an osteoblastic osteosarcoma was made. The patient was advised chemo and radiotherapy and was discharged. She was subsequently lost to

The exact cause of osteosarcoma is unknown. osteoblasts and malignant osteoids IHC:SATB2 and AKP are positive, TP53 alteration and MDM2 amplification

High SATB2 expression in osteosarcoma patient samples was associated with poor clinical outcome. N-cadherin was one critical downstream target gene of SATB2 that mediated the stem cell-like phenotype. Reduction of SATB2 or N-cadherin resulted in NF-kB inactivation, which led to impaired osteosarcoma sphere formation and tumor cell proliferation. SATB2 is a marker of osteoblastic differentiation in benign and malignant mesenchymal tumours. Although SATB2 is not specific for osteosarcoma, it has the potential to be a useful adjunct in some 2019-07-05 · 1. Anticancer Agents Med Chem. 2019 Jul 5.

Satb2 osteosarcoma

SATB2 is commonly expressed in osteosarcomas. Although apparently being a valuable diagnostic marker for differentiating between small cell osteosarcoma (SCO) and other small round cell tumors of All osteosarcomas were positive for SATB2 in both single cells and multinucleated cells with variable expression for CD68 and MITF. Only 1 out of 5 cases was positive (more than 50% of cells) for P63. Conclusions: Results suggest that SATB2 expression may present in significant numbers of GCTBs.

Only 1 out of 5 cases was positive (more than 50% of cells) for Small round cell osteosarcoma is a very rare type of osteosarcoma, histologically mimicking other small round cell malignancies of bone, most notably Ewing sarcoma.To distinguish small cell osteosarcoma from other primary small cell malignancies of bone, we evaluated the immunohistochemical (IHC) expression of CD99 and SATB2, a marker of osteoblastic differentiation. Diagnosing extra skeletal osteosarcomas at rare sites can be quite challenging as it might mimic hyalinized stroma.

Small round cell osteosarcoma is a very rare type of osteosarcoma, histologically mimicking other small round cell malignancies of bone, most notably Ewing sarcoma.To distinguish small cell osteosarcoma from other primary small cell malignancies of bone, we evaluated the immunohistochemical (IHC) expression of CD99 and SATB2, a marker of osteoblastic differentiation.

In addition, SATB2-AS1 is specifically involved in the PI3K-Akt signaling pathway, which can affect the epithelial–mesenchymal transition in numerous ways to influence tumor aggressiveness . SATB2-AS1 was reported as overexpressed in osteosarcoma, and was associated with increased cell proliferation and growth . 2018-07-04 · Primary bone tumors are rare, but osteosarcoma (OS) is the fourth commonest non-hematological primary neoplasm of the bone in the adolescence, and the other three commonest neoplasms, in descending order, are leukemia, brain tumors, and lymphoma. The commonest presenting complaints are swelling and aches. These tumors cannot be diagnosed without the help of radiology. There is a wide age range positive for SATB2, and 2 SATB2–negative cases were positive for CDH-17. Therefore, CDH-17 and SATB2 are complementary and, when used together, could identify all MC.5 IV. Other markers available for detection of metastatic CRC Dragomir, et al reports that SATB2 marker alone had 93% sensitivity and 77% specificity in determining CRC. Small round cell osteosarcoma is a very rare type of osteosarcoma, histologically mimicking other small round cell malignancies of bone, most notably Ewing sarcoma.

Objective. Special AT-rich binding protein 2 (SATB2) is an immunohistochemical marker for osteoblast differentiation. Our aim was to investigate SATB2 expression in oral osteosarcoma and other bone-producing oral tumors/reactive lesions to evaluate its usefulness as a diagnostic marker. Forty‐eight pretreated osteosarcoma biopsies, including 26 whole‐section cases and 22 tumours on tissue microarrays, and 36 non‐osteogenic bone sarcomas were evaluated.

SATB2 and pluripotency-associated gene expression in osteosarcoma CSCs were analyzed using. qRT-PCR and Western blotting. The sphere for- mation assay, SATB2 is commonly expressed in osteosarcomas. Although apparently being a valuable diagnostic marker for differentiating between small cell osteosarcoma In the present study, we describe the expression profile of lncRNAs in osteosarcomas compared with paired adjacent non-cancerous tissue (n=7) using microarray Histochemical staining of alkaline phosphatase can demonstrate the osteoblastic nature of the tumor. Novel immunohistochemical markers SATB2 and DMP1 May 6, 2020 For example, SATB2 overexpression increased cell proliferation, stem cell-like gene expression and tumor growth in osteosarcoma (6); and In addition, SATB2 was found to repress the expression of several Hox genes including Hoxa2, an inhibitor of bone formation and regulator of branchial arch May 8, 2020 diagnosis, the tumor showed diffuse strong nuclear positivity for SATB2 by immunohistochemistry, supporting the diagnosis of osteosarcoma.

SATB2 is a marker of osteoblastic differentiation in benign and malignant mesenchymal tumours. Although SATB2 is not specific for osteosarcoma, it has the potential to be a useful adjunct in some settings, particularly in the distinction between hyalinized collagen and osteoid. SATB2 is a highly sensitive marker for osteosarcomatous differentiation in gynecologic tract carcinosarcoma, and is also highly specific when used to differentiate osteosarcoma from chondrosarcoma and rhabdomyosarcoma elements in these tumors. SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating osteosarcoma from non-malignant osteoblastic lesions.

2016-09-01 · SATB2 is commonly expressed in osteosarcomas. Although apparently being a valuable diagnostic marker for differentiating between small cell osteosarcoma (SCO) and other small round cell tumors of bone, for instance Ewing sarcoma family of tumors (ESFT), it has not been tested in a large series of ESFT and chondrosarcomas so far.

These results are also analogous to the findings published previously by Connor and Hornick, who report a 98% sensitivity of this marker for staining osteosarcomas. SATB2 plays an important role in regulating osteosarcoma stem cell-like properties and tumor growth. The combination of conventional chemotherapy and metformin may be a promising therapeutic strategy for osteosarcoma patients. Conclusion: SATB2 is a reliable osteoblastic marker for differential diagnosis of osteosarcoma and non-osteoid sarcoma, although with a limited role in separating osteosarcoma from non-malignant osteoblastic lesions.
