Glioblastoma treatment: planning the first operation and what follows

Get the diagnosis and immediate priorities clear

A brain scan can suggest glioblastoma, but the treatment discussion needs the tissue diagnosis and molecular findings. Ask for the integrated pathology report, including IDH status and MGMT promoter methylation testing. These results help clarify the tumor type and the likely value of temozolomide. A diagnosis of IDH-mutant grade 4 astrocytoma follows a related but distinct classification.

Bring a short description of changes in speech, movement, memory and seizures. Those changes help the team judge urgency and establish a starting point for recovery. New severe weakness, repeated seizures or declining alertness needs urgent local assessment while longer-term treatment is being organized.

Plan removal around the functions you need

The surgical goal is to remove as much tumor as can be removed safely. Its position relative to language, movement and other important networks affects that balance. Some patients have a biopsy because a larger operation would carry too much risk or because the tumor is difficult to reach.

Ask the surgeon what function is most at risk, what imaging or mapping will guide the operation, and what a successful recovery would look like. If you have a job, hobby or caregiving role that depends on a particular ability, describe it. That makes the conversation about surgical tradeoffs much more concrete.

Use the postoperative review to connect the next steps

The next decision combines the operation report, postoperative MRI, pathology and physical recovery. Even after visible tumor has been removed, glioblastoma cells can remain beyond the surgical area, which is why additional treatment is normally discussed.

Before discharge, establish who will arrange radiation oncology and neuro-oncology review. Ask when the wound should be checked, how seizure or steroid medicines will be managed, and whom to contact if symptoms change. A named next appointment is more useful than leaving with an open-ended instruction to seek further treatment.

Understand how radiation and temozolomide fit together

For many adults well enough for combined treatment, radiation is given with daily temozolomide, followed by a period of temozolomide alone. The radiation schedule and chemotherapy plan are adjusted to the person's condition. Older or frailer patients may be offered a shorter radiation course or a different balance of treatments.

MGMT promoter methylation can help estimate sensitivity to temozolomide, particularly when choosing treatment for older patients. Ask the team to explain what your result changes in your own plan. Blood counts, infection risk, nausea and fatigue also need a practical monitoring schedule during treatment.

Ask about additional treatment at the right point

Some centers discuss tumor-treating fields alongside maintenance treatment. This involves a device used for long periods each day and requires attention to scalp care and daily routines. If it is offered, discuss the expected benefit together with the time, assistance and expense involved.

Clinical trials can also be relevant early in care. Share the trial name with the treating team before changing the established schedule. Screening often depends on the operation, tissue availability and treatment already received, so this discussion is easiest while those details are being assembled.

Build support into the treatment calendar

Weakness, word-finding difficulty and fatigue can make ordinary tasks surprisingly demanding. Rehabilitation, speech therapy and practical help at home can run alongside cancer treatment. Ask which activities are safe, whether driving restrictions apply and how a caregiver can recognize a seizure or medication problem.

Write down the steroid dose and any planned taper, rather than adjusting it according to how you feel on one day. Keep a symptom record that includes sleep, appetite, mobility and concentration. At follow-up, those details help the team separate treatment effects from changes that need further investigation.

Know how the first follow-up scans will be used

MRI follow-up is interpreted alongside symptoms, medication use and the timing of radiation. Treatment-related changes can sometimes resemble growth. If a scan is uncertain, ask what finding would lead to observation, another scan or an additional test.

It helps to retain the original MRI files from before surgery onward. A clinician comparing the full sequence can understand changes more clearly than someone reviewing a single report. Keep copies of the radiation plan and chemotherapy dates as well, since they will matter if treatment later needs to change.

Prepare a focused Shanghai neuro-oncology review

Huashan Hospital has glioma and neurosurgical services. A useful review can address the surgical plan, integrated diagnosis or the sequence of postoperative treatment. Our existing glioma resource helps place those questions within the broader care pathway.

Send EastMedGo the MRI files, pathology and molecular reports, operation note if available, and current medicines. Tell us which decision is pending and when your local team expects treatment to start. Through EastMedGo, we can help organize the records and coordinate a relevant consultation request, with travel planning built around the medical timetable.
