It depends on what you mean by success. And that question matters more than most families realise when they first ask it.
“Success rate” flattens everything into one figure that doesn’t apply equally to every case. A meningioma in an accessible location is a completely different surgical picture from a glioblastoma in eloquent cortex. What actually determines outcome is tumor type, grade, location, how much can safely come out, and what happens after surgery. The surgery is one part of that.
Dr. Gurneet Singh Sawhney is a neurosurgeon at Fortis Hospital Mumbai with 18 years managing brain tumor cases across all grades. The success conversation in his clinic starts with specifics not a generic percentage.
Trying to understand what surgery can realistically do for your case?
What Success Looks Like Across Different Tumor Types
Because tumor type changes everything about what outcomes are possible.
Benign tumors meningiomas, pituitary adenomas, acoustic neuromas: These are where surgery delivers its clearest results. Gross total resection rates for accessible meningiomas run above 90 percent at experienced centres. Recurrence after complete removal is low. Pituitary tumors are often removed entirely through the nose without a craniotomy. For benign tumors, surgery done well at a dedicated centre has a high probability of durable tumor control. Patients already researching brain tumor surgery in Mumbai will find outcomes at experienced Mumbai centres broadly comparable to international standards for these tumor types.
Low-grade gliomas grades 1 and 2: Slower growing. Surgery aims for maximum safe resection how much comes out depends on location and what’s nearby. Extent of resection correlates directly with time to progression. More out means longer before it returns. Median survival for well-resected low-grade gliomas runs into years sometimes a decade or more for grade 2. Not a cure. But real, functional time. Families who’ve read about whether neurological problems can exist with normal scans arrive already understanding that post-operative imaging tracks resection extent over time.
High-grade gliomas glioblastoma, grade 4: This is where the numbers get harder. GBM is aggressive and recurs. Median survival with surgery plus radiotherapy plus chemotherapy sits around 14 to 16 months. Some patients do better. Surgery here isn’t curative but maximal safe resection improves both survival and quality of life compared to biopsy alone. The goal shifts from cure to the best possible function for the best possible time.
What Determines Your Individual Outcome
Extent of resection: The single biggest surgical variable for most gliomas. Gross total resection consistently outperforms subtotal in outcomes data. But how aggressively the surgeon can operate depends on location which is why functional mapping matters before the first incision.
Surgeon volume and centre capability: Complication rates are lower at high-volume centres with intraoperative monitoring, dedicated neurosurgical ICU, and experienced teams. A procedure that goes well and one that goes well with function preserved aren’t the same thing.
What happens after surgery: Adjuvant therapy, surveillance imaging, rehabilitation. Surgery opens the window. What gets done in that window shapes the long-term outcome.
As a Neurosurgeon in Mumbai who has managed brain tumor cases across all grades for 18 years, Dr. Sawhney’s pre-surgical conversation covers what surgery can and can’t contribute specific to that tumor, that location, that patient.
Why Choose Dr. Gurneet Singh Sawhney
Dr. Sawhney trained under Prof. Taira at Tokyo Women’s Medical University for functional neurosurgery and under Prof. Sugano at Juntendo University for epilepsy surgery. Two full fellowships at high-volume centres. Back at Fortis Hospital Mulund West, the pre-surgical workup includes functional MRI, tractography where indicated, and neuropsychological baseline. Awake craniotomy is available for tumors near eloquent cortex. The post-surgical conversation is honest about what was achieved, what comes next, and what the realistic trajectory is. Families come in wanting a success rate. They leave with something more useful a case-specific answer about what surgery can do for them.
FAQ's
What is the success rate of brain tumor surgery in Mumbai?
It varies by tumor type benign tumors like meningiomas have resection rates above 90 percent at experienced centres, while high-grade gliomas have a different outlook where surgery improves survival and function without offering a cure.
Does extent of tumor removal affect survival?
Yes for most gliomas, greater resection extent directly correlates with longer time to progression and better overall survival, which is why maximising safe removal is a primary surgical goal.
Is brain tumor surgery in Mumbai comparable to international standards?
At dedicated centres with intraoperative monitoring, awake craniotomy capability, and experienced teams, outcomes in Mumbai are broadly comparable to international centres for the same tumor types.
What follow-up is needed after brain tumor surgery?
Post-operative MRI, adjuvant radiotherapy and chemotherapy for high-grade tumors, regular surveillance imaging, and rehabilitation where needed surgery is one part of a longer treatment picture.
How do I consult Dr. Gurneet Singh Sawhney about brain tumor surgery in Mumbai?
Call +91 8104310753 or email gurneetsawhney@gmail.com he reviews imaging before the consultation at Fortis Hospital, Mulund West, Mumbai, so the outcome discussion is specific to your case.
