Glioma
Treatment options in Shanghai

MRI shows the lesion and its relationship to brain structures, while functional tests help assess abilities that may be at risk. During suitable operations, stimulation and monitoring can help the surgeon identify important areas as the procedure proceeds. These techniques add information; they do not create a perfect boundary between tumour and essential brain tissue or remove all uncertainty. Ask which preoperative and intraoperative assessments are proposed, what each contributes and how a concerning functional response would alter the operation. The practical value is how the information informs a decision to continue, pause or limit removal.

Awake brain surgery allows selected patients to perform tasks such as naming pictures, speaking or moving while the team monitors function. Depending on the plan, a person may be awake for only part of the operation. It is not required for every glioma near a functional region, and suitability depends on the surgical and anaesthetic assessment and the ability to participate. Discuss anxiety, communication difficulties and existing deficits before agreeing to a plan. Ask how preparation, comfort and unexpected difficulty with testing would be handled, and what alternative approach the team would consider.

Ask what findings would lead the surgeon to leave tumour behind and how that possibility would affect later treatment. Maximum removal and maximum safe removal are not interchangeable goals. Surgery can cause temporary or permanent problems with speech, movement, vision or memory, and also carries risks such as bleeding, infection, seizures and stroke. Mapping can help reduce avoidable injury but cannot guarantee preserved function. Discuss what different deficits would mean for daily independence and who would assess and support recovery. A clear explanation of tradeoffs is more useful than a percentage detached from your anatomy and baseline function.
