Apoptosis and Colorectal Carcinoma; a Multiparameter Immunohistochemical, and Computerized Image Analysis Study

Apoptosis and Colorectal Carcinoma; a Multiparameter Immunohistochemical, and Computerized Image Analysis Study
ABSTRACT: The last few years showed an increase in the incidence of the colorectal cancer in Egypt. Between 20% and 50% of patients with this cancer are susceptible to death within five years of diagnosis. Tumor growth results from a disturbance in the balance between the rates of cell proliferation and cell death (apoptosis). We studied the expressions of proteins ... Read more

Use of Cyclo-oxygenase (COX)-2 Expression and Ki-67-Labeling Index (LI) in the Differntiation between Osteoblastoma and Osteosarcoma

2018-09-06 09:04:32 Keywords Osteosarcoma, Osteoblastoma, Ki-67, COX-2,
Use of Cyclo-oxygenase (COX)-2 Expression and Ki-67-Labeling Index (LI) in the Differntiation between Osteoblastoma and Osteosarcoma
BACKGROUND: Osteoblastoma and osteosarcoma are primary bone forming tumors that show different clinical behavior and radiological/pathological features. In the majority of cases the two entities may easily be separated. Occasionally, however osteoblastoma may resemble osteosarcoma histologically, and the differential diagnosis between aggressive osteoblastoma and low grade osteosarcoma may be very difficult or even impossible on a small biopsy sample. AIMS: ... Read more

Ki-67 and Osteocalcin Immunostaining Expression in Osteogenic Tumors; Osteoblastoma and Osteosarcoma

2018-09-06 09:07:06 Keywords Osteosarcoma, Osteoblastoma, Osteocalcin, Ki-67,
Ki-67 and Osteocalcin Immunostaining Expression in Osteogenic Tumors; Osteoblastoma and Osteosarcoma
_BACKGROUND/AIMS:_ Osteoblastoma and osteosarcoma are primary bone forming tumors that show different radiological/pathological features and clinical behavior. This study aims to specify the expression profile of Ki-67 and osteocalcin in osteoblastomas and osteosarcomas._METHODS:_Ki-67 and osteocalcin immunoexpression were studied in 9 osteoblastomas and 30 osteosarcomas; including 27 osteoblastic osteosarcomas._RESULTS:_There was gradual significant increase (pCONCLUSION:_ Ki-67 increased ongoing from osteoblastomas through low ...

Utility of Ki-67 labeling index in the differential diagnosis of osteogenic bone tumors

2018-09-09 18:07:01 Keywords osteogenic tumors, labeling index. differential diagnosis, Ki-67,
Utility of Ki-67 labeling index in the differential diagnosis of osteogenic bone tumors
Background and Aims: A group of osteogenic bone tumors can be diagnostically challenging at the histopathological level. These include aggressive osteoblastoma and osteoblastoma-like osteosarcoma. This study aimed at assessing the utility of Ki-67 labeling index in the differentiation between these types of neoplasms. Methods: A total of 39 patients were enrolled in this study, including 9 osteoblastomas (6 conventional and ... Read more
