The Top-Five Things I learned as a First-Time Attendee at SABCS 2025 by Sara Zimov

Walking into the San Antonio Breast Cancer Symposium (SABCS) for the first time this December was pleasantly overwhelming. There were 11,000 attendees from 102 countries, all focused on advancing breast cancer science! Here are the top five takeaways most relevant to our IBC community.

1. IBC Finally Has Diagnostic Codes—A Game-Changing Achievement

The biggest announcement at SABCS 2025 was the successful effort of the IBC Collaborative to create specific ICD-10 diagnostic codes for inflammatory breast cancer. These codes went into effect on October 1, 2025.

The three codes—C50.A0 (unspecified inflammatory carcinoma of breast), C50.A1 (inflammatory carcinoma of right breast), and C50.A2 (inflammatory carcinoma of left breast)—mark a major win for the IBC community. Led by our own IBCRF in collaboration with Susan G. Komen and the Milburn Foundation, this achievement means IBC is no longer buried within general breast cancer codes.

Lindsey Anstine, Ph.D., presented strong data illustrating why this matters. Healthcare providers can now accurately document IBC in medical records, which helps with tracking prevalence, outcomes, and treatment patterns. Researchers can find IBC patients in databases more accurately. Insurance companies and healthcare systems can understand IBC’s specific treatment requirements. Most importantly, patients may receive correct diagnoses more quickly, avoiding dangerous delays that occur when IBC is misdiagnosed.

2. The IBC Scoring System Is Revolutionizing Diagnosis

An equally important change is the adoption of the IBC Scoring System. Since its launch in August 2023, it has been used over 6,000 times in 114 countries. This tool tackles a key issue: even experienced clinicians often disagree on the diagnosis of IBC because it has been subjective. Physicians sometimes argue about whether the breast is “inflamed enough” to qualify as IBC.

The scoring system makes diagnosis more objective by evaluating clinical, pathologic, and imaging characteristics on a scale from 0 to 48. Each characteristic gets a score between 0 and 3, which is then multiplied by a priority factor that values features specific to IBC more heavily. The total score helps classify patients into categories like “definite IBC” (highest scores), “strong possibility,” or “locally advanced breast cancer.”

At SABCS, Dr. Anstine reported that more tumor boards and multi-institutional networks are using the tool, indicating it is practical for clinicians. The online calculator at komen.org/ibc makes it easy for providers worldwide to access the tool.

This is important because correct diagnosis leads to appropriate treatment. IBC needs aggressive trimodal therapy—neoadjuvant chemotherapy, mastectomy, and radiation—right from the start. Patients misdiagnosed with less aggressive disease may get inadequate initial treatment, allowing the cancer to spread.

3. Patient Advocates Shape Research—Not Just Observe It

I was curious about the role of advocates at a scientific conference like this. It turns out, we are essential to the research process.

Twenty-four patient advocates participated as panelists and speakers in the scientific program, with four on the SABCS 2025 Program Committee. This involvement ensures that patient viewpoints influence which research is funded, how studies are structured, and how findings are communicated.

The Advocate Lounge became my home base during the conference. Conversations there went beyond science to real-world implications. These stories are why advocates fought for a decade to establish IBC’s own diagnostic codes. They’re why the scoring system is so important. We’re not only translating research; we’re making sure it addresses the real issues that endanger lives.

4. The IBC Research Task Force Is Charting the Path Forward

Dr. Anstine’s presentation highlighted systematic efforts to identify knowledge gaps in IBC biology through the IBC Research Task Force convened by the IBC Collaborative. This expert panel is figuring out what we need to learn about how IBC starts, spreads, and how it can be monitored—insights that will direct future funding towards IBC-specific questions.

This is crucial because IBC makes up 2-4% of breast cancer diagnoses but accounts for 10% of breast cancer deaths. It has a far greater impact on mortality than its numbers suggest. Yet it has been greatly understudied.

The IBC Research Task Force is prioritizing questions such as: What drives IBC’s rapid growth? Why does it spread into dermal lymphatics so easily? Can we find biomarkers for early detection? How can we monitor treatment response more effectively?

5. Precision Medicine Advances Offer Hope for IBC

Several themes from SABCS 2025 have direct implications for IBC patients, particularly regarding more precise diagnosis and treatment monitoring.

Liquid biopsy technology, which detects circulating tumor DNA in the blood, was a hot topic at the conference. For IBC, where close monitoring is vital, the ability to find minimal residual disease early and identify resistance mutations as they appear could be groundbreaking. Real-time monitoring of treatment response can allow for therapy adjustments before clinical progression is evident.

Research presentations also highlighted new treatment targets, including TROP2 and CCR7. The expanding treatment options provide hope for appropriate patients, including those with IBC, whose cancers do not respond to standard therapies.

Final Reflections

With new diagnostic codes that enable accurate documentation, a validated scoring system that standardizes diagnosis, dedicated research task forces identifying knowledge gaps, and major cancer centers investing in IBC programs, IBC is beginning to receive the attention it deserves.

For advocates thinking about attending SABCS: the conference genuinely values patient voices. Lower registration fees, dedicated lounges, and integrated patient involvement show that SABCS understands we are essential partners in research, not just recipients.

My first SABCS left me inspired by thousands of researchers and advocates working toward better outcomes—and reminded of how much we still need to learn about IBC. But after seeing the new diagnostic infrastructure finally in place, I’m convinced more now than ever that we are moving fast in the right direction.

Finding the best IBC care for YOU! by Phyllis Johnson

Once upon a time finding treatment for inflammatory breast cancer (IBC) was a daunting task. While there were experts scattered around, they didn’t offer coordinated care for oncology, surgery, and radiation.  Then in 2006 MD Anderson opened the first IBC clinic that combined oncology, surgery, and radiation expertise at a research hospital. Duke and Dana Farber soon followed with dedicated IBC clinics.

So, if you are recently diagnosed with IBC, do you need to go to one of these well-known clinics? Not at all! Now there are more choices. The James Cancer Hospital in Ohio, the Memorial Sloan Kettering Cancer Center in New York, the Sidney Kimmel Cancer Center – Jefferson Health in Pennsylvania, and others have IBC clinics now.

Another factor to consider is that some of the doctors who led the research and pioneering techniques in IBC treatment at these “biggies” have gone to other hospitals taking their expertise with them and sharing it with their new institutions. In addition, many of the more than 70 designated comprehensive cancer centers in the United States have experience with IBC.

So, if you are within driving distance of a dedicated IBC clinic or comprehensive cancer center, it makes sense to go where the experts are. However, suppose you live far away from major hospitals. Can you get quality care with a local oncologist? Yes, maybe. Consider these factors:

  1. Is the doctor familiar with trimodal care for IBC? Your treatment plan for a Stage 3 IBC diagnosis should start with a systemic treatment like chemotherapy, followed by a mastectomy, and radiation. If your doctor wants to start with surgery, you need a different doctor! See the IBC Research Foundation website for more information about what your treatment should include.
  2. Is your doctor willing to consult with an IBC expert at one of the major clinics? There are so many variables with different IBC subtypes, new drugs, and your own medical history, that a second opinion about your care is a good idea. This is especially important if you are diagnosed at Stage 4.
  3. Is your doctor realistically optimistic? You don’t want a doctor who gives you six months to live or one who promises a quick cure.
  4. Can you divide where you get your care based on your local options? You may opt to get chemotherapy close to home, but go to a surgeon who has done more IBC mastectomies or to a hospital with the latest radiation machines.
  5. What will your insurance pay for? Be sure to check the fine print for any going “out of network” charges.
  6. Are there other factors in your life like children living at home or work responsibilities that make travel difficult?

Today’s doctors have access to an array of resources that allow them to send imaging results and to consult with experts a world away. Whether you live next door to a world renowned clinic or far away, you can get the treatment you need.
