[Comment] Benefit with adjuvant chemotherapy in anaplastic astrocytoma
The role of chemotherapy for newly diagnosed anaplastic gliomas, particularly when combined with radiotherapy, has long been unresolved. Over the past few decades, despite no conclusive data, study findings have suggested that the addition of nitrosourea-based chemotherapy to radiotherapy could be beneficial. The NOA-04 trial1 revealed that initial treatment with chemotherapy (either temozolomide or procarbazine, lomustine, and vincristine [PCV]) or radiotherapy alone yielded similar results. Survival of patients with anaplastic glioma has been recognised as being strongly dependent on the presence or absence of the favourable 1p/19q co-deletion.
