The Ki-67 proliferation antigen in meningiomas. Experience in 600 cases

Acta Neurochirurgica, 2004
Meningiomas are mostly benign tumours that can be cured by surgical resection. Because meningiomas tend to recur, long term management in patients with subtotal tumour resection remains controversial. Previous studies have shown that the proliferation potential of meningiomas by Ki-67 labelling indices (LI) might predict their natural history.

Effects of Serum Deprivation on Ki‐67‐reactive Antigen

Acta Pathologica Japonica, 1989
In order to elucidate the relationship between the level of cellular Ki‐67‐reactive antigen and cell proliferation activity, the effects of serum deprivation on the antigen expression and cell proliferation of HeLa cells were investigated using flow cytometry.

Prognostic value of the proliferation-related antigen Ki-67 in oligodendrogliomas

Cancer, 1996
In various neoplasms expression of the proliferation-related Ki-67 antigen has successfully been linked with parameters of progression of disease. While a definite grading scheme for oligodendrogliomas has still not been agreed upon, any parameter of tumor proliferation that might be helpful in predicting clinical outcome should be evaluated.The ...

Ki-67 antigen expression and growth pattern of basal cell carcinomas

Archives of Dermatological Research, 1993
The expression and location of the Ki-67 antigen was investigated in 62 basal cell carcinomas (BCC) using immunostaining techniques (PAP and APAAP) on cryostat sections. The tumor samples were classified into three groups according to microarchitecture (nodular, superficial or fibrosing).

Proliferating normal bone marrow cells do stain for Ki‐67 antigen

British Journal of Haematology, 1993
Summary The normal human bone marrow has been investigated in the past for the presence of the proliferation associated antigen detected by the Ki‐67 antibody and aberrantly low scores for this antigen have been reported. We used a new Ki‐67 equivalent antibody (MIU 1) and a formalin fixation of smears and trephine biopsies, and we report 52.8%±9.2 SD ...

Expression of Melanocyte Differentiation Antigens and Ki-67 in Nodal Nevi and Comparison of Ki-67 Expression With Metastatic Melanoma

The American Journal of Surgical Pathology, 2002
Nodal nevi represent a potential diagnostic pitfall in the analysis of lymph nodes. They may be confused with metastatic melanoma or carcinoma. Although several morphologic guidelines exist for the recognition of nodal nevi, on occasion immunohistochemical studies may be helpful for diagnosis, especially when melanocytes extend into the lymph node ...

Expression of p53, MDM2 protein and Ki-67 antigen in recurrent meningiomas

Journal of Neuro-Oncology, 1998
Association of p53 gene abnormalities with tumor progression and prognosis of many neoplasms has been demonstrated, but little is known about the clinical significance of p53 abnormalities in meningiomas. The significance of p53 protein expression in recurrent meningiomas and its relationships with MDM2 protein and proliferation activity were ...

Histochemistry of Ki-67 antigen in ameloblastomas.

Journal of Osaka Dental University, 2000
The proliferative potential of two common histologic variants of ameloblastoma was investigated immunohistochemically using Ki-67 antibody on routinely processed, formalin-fixed, paraffin-embedded sections. Thirty cases of ameloblastomas (15 cases of follicular and 15 cases of plexiform type) were analyzed.

[Flow cytometric analysis of Ki-67 reactive antigen].

Nihon rinsho. Japanese journal of clinical medicine, 1992
Monoclonal antibody Ki-67 is a useful and easy means for evaluating cell proliferative activity. Furthermore, it appears to provide valuable prognostic informations in some neoplastic diseases. However, almost all studies on solid tumors were performed only by microscopic observation using immunohistochemistry, and not by flow cytometry. Therefore, the
