Transformation From Atypical to Anaplastic Metastatic Meningioma: Evolutionary Turning Point Marked by Strong 18 F-FDG Avidity and Uptake Collapse From 68 GA-DOTATOC.

World Health Organization (WHO) grade III anaplastic meningioma is scarce. In this way, most studies compared WHO grade I and II. Otherwise, some authors are uncertain about using 18 F-FDG as a diagnostic tool to estimate the WHO grade, especially high.

Role of radiotherapy in the management of rare gynaecological cancers.

There are a large number of gynaecological cancers with rare histologies, for which the available data are limited and usually retrospective. Because of their rarity and poor prognosis, the management of these cancers must be centralized in expert centres, for both histological diagnosis and treatment. With the exception of sarcomas, most endometrial or cervical cancers with rare histologies respond to the same radiation treatment modalities than cancers with more common histologies, although there are some specificities regarding treatments such as neuroendocrine carcinomas (chemotherapy with platinum and etoposide, major role of surgery).
