Question 1

What is the definitive test for brain tumours?

Dr. Rahul Gupta · Accepted Answer

The definitive test is the histopathological examination of the biopsy sample taken during surgery.

Question 2

What are the post-operative complications of brain tumour surgery?

Dr. Rahul Gupta · Accepted Answer

The most important are seizures and post-operative brain edema. There can be neurological deficits if the motor cortex or another important area was operated on, and nerve injury if the surgery involved the skull base. Uncommonly, there can be post-operative hemorrhage or infection.

Question 3

What are the important post-operative issues to follow, and how often should a brain tumour patient have follow-up imaging?

Dr. Rahul Gupta · Accepted Answer

Patients need regular follow-up with the neurosurgeon and repeated imaging. If it is a malignant tumour, a contrast MRI is needed roughly every 3 to 6 months. If the patient has a benign tumour and surgery went well, the MRI can be repeated once a year.

Question 4

In which type of brain tumour is the prognosis so poor that surgery, chemotherapy and radiotherapy offer no benefit?

Dr. Rahul Gupta · Accepted Answer

This applies mainly at the extremes of age: very large tumours in infants, or very large tumours in elderly patients involving critical areas of the brain. For brain stem and deep-seated thalamic gliomas presumed to be malignant, a biopsy may not even be taken, since these are treated directly with radiotherapy. Glioblastomas (grade 4 gliomas) carry a poor prognosis, though chemotherapy and radiotherapy can still extend survival and quality of life for that shorter span of time.

Question 5

How can post-operative complications be reduced in a resource-limited area?

Dr. Rahul Gupta · Accepted Answer

Four things are essential. MRI is mandatory, brain tumour surgery should not be performed without it. An operating microscope is needed for magnification, even a basic one without fluorescence or navigation add-ons. The anaesthetist needs to be equipped and experienced in controlling brain swelling and blood pressure during surgery, ideally with a year or two of experience at a neuro centre. And a post-operative ICU with ventilator support is needed, since some patients require ventilation for a day or two. Good post-operative ICU care alone can reduce complications by 25 to 30 percent. With these four in place, superficial tumours such as meningiomas, surface gliomas and straightforward intraventricular tumours can be safely removed; difficult tumours should still be referred to a better-equipped centre.

Question 6

What is the commonest brain tumour, and which type has the worst prognosis?

Dr. Rahul Gupta · Accepted Answer

Metastasis used to be the most common brain tumour, but with better radiotherapy and chemotherapy most metastatic cases are now managed by radiation and medical oncology rather than surgery, except when a solitary large metastasis is causing a symptomatic mass effect. The tumours operated on most often today are gliomas and meningiomas. Gliomas run from grade 1 to grade 4, and grade 4 glioblastomas have the worst prognosis. Meningiomas usually have a good prognosis, though some are atypical or malignant and located at difficult skull-base sites near major vessels; those can be treated with modern radiotherapy such as gamma knife or cyberknife after a subtotal resection. Pituitary tumours are third most common and are usually benign, approached endoscopically through the nose.

Question 7

After surgery, do all patients systematically need rehabilitation?

Dr. Rahul Gupta · Accepted Answer

Yes. All patients need post-operative care from a team of physiotherapists and rehabilitative support. About 90 percent of patients who arrive without deficits leave hospital without one, but even they need psychological support, and patients with malignant tumours need considerably more of it given the chemotherapy and radiotherapy ahead. Patients need to see the neurosurgeon and physiotherapist regularly for at least 3 to 6 months, and continue lifelong follow-up MRIs.

Question 8

What surgical technique is used for this kind of procedure?

Dr. Rahul Gupta · Accepted Answer

The full presentation covered the range of techniques used, from neuronavigation and awake craniotomy to fluorescence-guided resection and endoscopic approaches, depending on the tumour's location and type.

Question 9

Is a drain placed after surgery?

Dr. Rahul Gupta · Accepted Answer

Yes, in around 80 percent of cases.

Question 10

In the event of cerebral edema, what technique should be used?

Dr. Rahul Gupta · Accepted Answer

Elective ventilation is used, along with decongestants such as mannitol or 3% saline. Sometimes the bone flap is deliberately not replaced immediately after surgery and is put back one to two months later.
