What is a multidisciplinary tumor board and should my Colorectal Cancer case be presented

Understanding Multidisciplinary Tumor Boards for Colorectal Cancer

What Is a Multidisciplinary Tumor Board?

A multidisciplinary tumor board (often called a "tumor conference" or "case conference") is a meeting where a team of cancer specialists from different medical fields reviews your case together. Think of it as bringing together all the experts who might be involved in your care to discuss your situation at the same time.

Who typically participates:

• Medical oncologists (chemotherapy specialists)
• Surgical oncologists (cancer surgeons)
• Radiation oncologists (radiation therapy specialists)
• Radiologists (imaging specialists who read scans)
• Pathologists (specialists who examine tissue samples)
• Gastroenterologists (colon and digestive specialists)
• Nurses and other care coordinators

Why This Matters for Colorectal Cancer

According to the NCCN Guidelines for Colon Cancer (Version 5.2025), the Panel explicitly states: "A multidisciplinary approach is necessary for managing CRC [colorectal cancer]."

This is important because colorectal cancer treatment decisions depend on multiple factors working together:

• Your tumor's stage and location (where it is in the colon)
• Pathology findings (what the tissue analysis shows)
• Biomarker status (genetic characteristics like MSI/MMR, KRAS, BRAF mutations)
• Whether surgery is possible (resectability)
• Whether you have metastatic disease (cancer spread to other organs)
• Your overall health and ability to tolerate treatment

Should Your Case Be Presented?

Yes—your colorectal cancer case should ideally be presented to a multidisciplinary tumor board, especially if:

✅ You have newly diagnosed colorectal cancer requiring treatment planning ✅ Your cancer is locally advanced (T4b tumors or bulky lymph node involvement) ✅ You have metastatic disease (cancer spread to liver, lungs, or elsewhere) ✅ Your case is complex or doesn't fit standard treatment patterns ✅ You're considering clinical trials as a treatment option ✅ Your tumor has specific biomarkers (MSI-H, dMMR, BRAF mutations, HER2 amplification) that affect treatment choices

The NCCN Guidelines emphasize that treatment recommendations can vary considerably based on biomarker results, which is exactly why having multiple specialists review your case together is valuable.

What Happens at Tumor Board?

The team will typically:

1. Review your imaging (CT scans, MRI, PET scans)
2. Discuss your pathology report in detail
3. Consider your biomarker testing results
4. Discuss surgical options (if applicable)
5. Recommend chemotherapy, radiation, or other systemic therapy based on your stage and risk factors
6. Identify any clinical trials you might be eligible for
7. Create a coordinated treatment plan that all specialists agree on

How to Request Tumor Board Review

Ask your oncologist directly: "Can my case be presented to the multidisciplinary tumor board?" Most cancer centers have this process built in, but it's worth confirming.

What to mention:

• You want input from multiple specialists
• You want to ensure all treatment options are considered
• You want a coordinated care plan

Most major cancer centers present cases routinely, and many insurance plans cover this as part of standard cancer care.

Key Questions to Ask Your Team

1. Has my case been (or will it be) presented to a multidisciplinary tumor board?
2. What were the recommendations from the tumor board?
3. Are there any clinical trials recommended for my specific biomarker status?
4. What is the rationale for the treatment plan being recommended to me?
5. If my case wasn't presented, why not, and can it be?
