Sources & medical oversight

  • Developed under the medical oversight of OpenCancer’s physician-scientist team (Chris Apfel, MD/PhD/MBA, CMO · Kaumudi Bhawe, PhD, CSO).
  • Last updated September 6, 2026. Informational only — not a substitute for your oncology team.

TL;DR: I can't predict your individual prognosis because I haven't received the specific reports you mentioned (MRI, CT scans, surgery details), and prognosis requires your doctor to evaluate your complete medical picture—but I can help you understand glioblastoma and what your Ki-67 score means once you share those documents.

KEY POINTS:

  • I need your actual reports to discuss your specific situation—please upload the MRI, CT, and surgery records you referenced
  • Ki-67 at 70% is a significant biomarker that tells us about tumor aggressiveness, but prognosis depends on many other factors (tumor location, extent of surgery, molecular markers like IDH and MGMT status)
  • Prognosis is individual, not generic—two patients with identical pathology can have very different outcomes based on factors only your care team knows
  • Your oncologist has the complete picture needed to estimate prognosis; I can help you understand the medical concepts and ask better questions
  • Glioblastoma treatment has evolved significantly with newer approaches, and your specific situation may open options worth discussing with your team

NEXT STEP: Upload the MRI report, CT scan results, and surgery/pathology details you mentioned, and I'll help you understand what they show and what questions to ask your oncologist about prognosis.

I Need Your Reports to Help You Understand Your Situation

You mentioned sending MRI reports, CT scans, and surgery billing details, but I haven't received those documents yet. To discuss your prognosis meaningfully, I need to see:

  • MRI findings (tumor location, size, extent of enhancement, edema)
  • Pathology report (confirmation of glioblastoma grade, molecular markers like IDH1/2 mutation status and MGMT methylation)
  • Surgery report (extent of resection—was it gross total resection, near-total, or partial?)
  • CT scan results (if done for staging or to assess for metastases)

Once you upload these, I can help you understand what they mean in plain language.


What Your Ki-67 Score Tells Us (Educational Context)

Your Ki-67 at 70% is an important piece of information. Here's what it means:

Ki-67 is a proliferation marker—it measures what percentage of tumor cells are actively dividing/growing. Think of it as a "growth rate" measurement:

  • Ki-67 < 30%: Lower proliferation (slower-growing)
  • Ki-67 30-50%: Moderate proliferation
  • Ki-67 > 50%: High proliferation (faster-growing)

Your 70% indicates high proliferation, which means your tumor cells are dividing rapidly. This is consistent with glioblastoma (which is inherently aggressive), but it's one data point among many that affects prognosis.


Why I Cannot Predict Your Individual Prognosis

This is critical to understand: Prognosis is NOT a one-size-fits-all number. According to the National Cancer Institute (NCI) and American Brain Tumor Association (ABTA) guidelines, glioblastoma prognosis depends on multiple interconnected factors:

Factors that significantly affect prognosis:

  1. Molecular markers (more important than grade alone):

    • MGMT methylation status: If your tumor's MGMT gene is methylated, you typically respond better to standard chemotherapy (temozolomide). This can substantially improve survival.
    • IDH1/2 mutation status: IDH-mutant glioblastomas have better prognosis than IDH-wildtype (which is more common in primary glioblastomas)
    • TP53 status: Affects treatment response
  2. Extent of surgical resection:

    • Gross total resection (removing all visible tumor) → better prognosis
    • Subtotal resection (most of tumor removed) → intermediate prognosis
    • Biopsy only (small sample taken) → more limited prognosis
    • This is why your surgery report matters enormously
  3. Tumor location:

    • Tumors in eloquent areas (speech, motor, vision centers) may be harder to remove completely
    • Location affects both prognosis and quality of life after treatment
  4. Age and performance status:

    • Younger patients generally have better outcomes
    • Overall health and ability to tolerate aggressive treatment matters
  5. Post-operative treatment received:

    • Standard of care: radiation + temozolomide chemotherapy
    • Newer approaches: tumor treating fields (TTF), immunotherapy trials, etc.

Without seeing your reports, I cannot tell you:

  • Whether your tumor was completely removed
  • Your MGMT and IDH status (these are game-changers)
  • Whether you're a candidate for clinical trials
  • What your specific treatment plan should be

What the Medical Literature Says About Glioblastoma Prognosis (General Context)

According to NCCN Guidelines for Central Nervous System Cancers and NCI data:

  • Median overall survival for newly diagnosed glioblastoma with standard treatment (surgery + radiation + chemotherapy) is approximately 14-15 months
  • 5-year survival is approximately 5-10%
  • However, these are population averages—individual outcomes vary widely based on the factors listed above

Important: These statistics are from patients treated with standard approaches. Newer treatments (immunotherapy, tumor treating fields, targeted therapies based on molecular markers) are improving outcomes, and your specific situation may be different.


Why Your Oncologist's Prognosis Estimate Matters More Than Mine

Your oncologist can tell you a prognosis because they have:

  • Your complete pathology report (including all molecular markers)
  • Your imaging (exact tumor location, size, relationship to critical brain structures)
  • Your surgery report (how much was removed)
  • Your age, health status, and ability to tolerate treatment
  • Knowledge of whether you're eligible for clinical trials or newer approaches

I can help you understand the concepts, but your doctor makes the prognosis estimate.


Questions to Ask Your Oncologist About Prognosis

Once you've had your initial consultation, these questions will help you understand your specific situation:

  1. "Based on my pathology (especially MGMT and IDH status) and the extent of surgery, what is your estimate of my prognosis?"

  2. "What factors in my case are most favorable, and what factors are most challenging?"

  3. "Am I a candidate for any clinical trials that might improve my outcome?"

  4. "What is the standard treatment plan for my specific situation, and are there newer approaches we should consider?"

  5. "How will we monitor my response to treatment, and what imaging/testing will we do?"

  6. "What support services (neuro-oncology, rehabilitation, palliative care) should I access now?"


What I Can Help You With Right Now

Please upload your reports, and I can:
