My Pancreatic Cancer is stable but not shrinking — is treatment still working

Understanding Stable Disease in Pancreatic Cancer

This is an important question, and the answer is more nuanced than you might expect. Yes, stable disease can represent meaningful treatment benefit, even though your tumor isn't shrinking.

What "Stable Disease" Actually Means

In oncology, doctors track three main responses to treatment:

1. Complete Response - No evidence of cancer visible on imaging
2. Partial Response - Tumor shrinks by at least 30% in size
3. Stable Disease - Tumor size stays roughly the same (doesn't grow or shrinks less than 30%)

Stable disease means your treatment is controlling the cancer's growth—preventing it from progressing. For pancreatic cancer specifically, this is clinically significant.

Why Stable Disease Matters for Pancreatic Cancer

According to research highlighted by Let's Win Pancreatic Cancer, stable disease is actually part of the success metric. In clinical trials studying combination immunotherapy approaches for pancreatic cancer, researchers counted both partial responses AND stable disease as "disease control." In one study, 77% of patients achieved disease control (combining partial responses and stable disease), and this durable control lasted a median of 7.8 months—significantly longer than the typical 3-month response duration with standard chemotherapy alone.

This matters because:

• Your cancer isn't progressing - The treatment is holding it in check
• You're gaining time - Stable disease buys time for your body to tolerate treatment and for new therapeutic options to emerge
• Quality of life may improve - Controlled disease often means fewer symptoms and better functioning

Questions to Ask Your Oncologist

To better understand YOUR specific situation:

1. "How long has my disease been stable, and what does the imaging show compared to my previous scans?" (This helps establish the durability of your response)

2. "Are there any tumor markers like CA 19-9 that we're tracking, and what do those trends show?" (Blood markers can provide additional information about disease activity beyond imaging)

3. "Based on my molecular profile and genetic testing, are there other treatment options we should consider if my disease starts to progress?" (This ensures you have a plan if circumstances change)

4. "What are the signs that would prompt us to change treatment, and how often will we reassess?" (Understanding the monitoring plan helps you stay informed)

5. "Are there clinical trials available for patients with stable disease that might offer additional benefit?" (Research is advancing rapidly in pancreatic cancer treatment)

The Broader Treatment Landscape

According to Dr. [removed] Strickler's insights from CancerPatientLab's "Navigating Pancreatic Cancer" webinar, pancreatic cancer treatment is entering an era of precision cancer medicine. This means:

• Molecular profiling matters - Your tumor's genetic mutations (KRAS, BRCA2, mismatch repair status, etc.) determine which treatments work best
• Combination approaches are improving outcomes - Chemotherapy combined with immunotherapy or targeted therapy often outperforms single-agent treatment
• New targeted therapies are emerging - KRAS inhibitors and other precision treatments are showing promise in clinical trials

Important Context

Stable disease in pancreatic cancer represents real clinical benefit. As noted in Let's Win Pancreatic Cancer resources, the field has made significant progress—survival times have improved, and patients are living longer with better quality of life than in previous decades. Your stable disease means the treatment strategy is working to control your cancer.

However, treatment decisions should always be individualized. Your oncologist considers:

• How long your disease has been stable
• Your overall health and tolerance of current treatment
• Your tumor's specific genetic profile
• Available clinical trials matching your situation
• Your personal goals and quality of life priorities
