Medulloblastoma: histopathologic and molecular markers of anaplasia and biologic behavior

Acta Neuropathologica, 2006
Large cell/anaplastic (LC/A) medulloblastoma (MB) is a recently recognized variant of medulloblastoma known to be associated with an advanced stage and a poor prognosis. Although Eberhart et al. suggested histopathologic grading of medulloblastoma in 2002, no consensus has been reached in terms of determining the criteria of an LC/A variant, and its ...

Anaplasia Rediviva

Annals of Internal Medicine, 1977
Anaplasia refers to the apparent retrogression toward an embryonic state that occurs in some human and animal tumors, the consequence, presumably, of a derepression of genes that would normally have been switched off in the course of development. The fetal substances newly formed in tumors are identified immunologically and are therefore referred to as

Spontaneous anaplasia in pilocytic astrocytoma of cerebellum

British Journal of Neurosurgery, 2003
We report a cystic cerebellar astrocytoma with a mural nodule that contained an additional focus of astrocytoma with the histological features of anaplasia, and showed up to 48% of aneuploid and 3% S-phase cells on flow cytometry. This focus was detectable on the enhanced, as well as non-enhanced T1 and T2 images.

Anaplasia and Heterogeneity of Gfap Expression in Gliomas

Tumori Journal, 1986
GFAP (glial fibrillary acidic protein) distribution was investigated in selected areas of glioblastomas and astrocytomas. The proliferating cell population of glioblastomas was GFAP negative and contained many mitoses which were also negative. The old, deeply located areas were composed of cells with visible cytoplasm, intensely GFAP-positive; mitoses ...

Herpesvirus infection and cervical anaplasia—a seroepidemiological study

International Journal of Cancer, 1977
AbstractIn a cohort of 23,146 pregnant females followed for 37–56 months subsequent to collection of prenatal sera, 57 cases of carcinoma of the cervix were encountered. Three controls were selected for each case from the residual cohort matched to cases for age, residence, number of prior cytology smears taken, and the date of entry to the study.
