Classified based on gross appearance', 'role': 'user'}, {'content': 'Answer: A \nExplanation: (A) Liver /Harrison16 - 2452]# Large majority of ASTROCYTOMAS arising in adults are high grade, supratentorial, and do not have a clearly defined margin.> Neoplastic cells migrate away from the main tumor mass an infiltrate adjacent brain, often tracking along white matter pathways.> Imaging studies do not indicate the full extent of the tumor.> These tumors are eventually fatal, although prolonged survival occurs in a few patients. Longer survival correlates with younger age, better performance status, and greater extent of surgical resection.> Late in their course, gliomas, especially those located in the posterior fossa, can metastasize along CSF pathways to the spine.> Metastases outside the CNS are rare.', 'role': 'assistant'}]
