How is Stomach Cancer that has spread to the liver treated

Treatment of Stomach Cancer with Liver Metastases

When stomach cancer spreads to the liver (called metastatic disease), treatment becomes more complex, but there are several established approaches your oncology team may consider.

General Treatment Framework

According to NCCN Guidelines, the treatment strategy depends on whether the liver metastases (cancer spots in the liver) can be surgically removed:

If Metastases Are Resectable (Can Be Surgically Removed)

The goal is curative intent—attempting to remove all visible cancer. Your care team typically considers:

1. Surgery-First Approach

   • Removal of the primary stomach tumor and liver metastases (either at the same time or in stages)
   • Followed by chemotherapy to eliminate any remaining microscopic disease

2. Chemotherapy-First Approach (Neoadjuvant Therapy)

   • Starting chemotherapy to shrink tumors before surgery
   • This can make surgery more feasible and may improve outcomes
   • Common regimens include FOLFOX or CAPEOX (combination chemotherapy drugs)
   • Surgery follows once tumors have responded adequately

If Metastases Are Unresectable (Cannot Be Surgically Removed)

When surgery isn't possible, systemic chemotherapy becomes the primary treatment:

• Intensive chemotherapy regimens like FOLFOX, CAPEOX, or FOLFIRI are standard
• These drugs circulate throughout your body to target cancer cells
• The goal shifts to controlling disease growth and extending survival
• Your oncologist may also consider targeted therapies or immunotherapy depending on specific tumor characteristics (biomarkers)

Important Considerations

Conversion Therapy: In some cases, chemotherapy can shrink initially unresectable tumors enough to make them surgically removable. This is called "conversion to resectability" and represents a potential opportunity for curative treatment.

Timing Matters: If surgery becomes an option after chemotherapy, timing is important—your surgical team will want to operate while you're still in good condition and before additional complications develop.

Questions to Ask Your Oncology Team

1. Are my liver metastases resectable or unresectable based on current imaging?
2. What is the recommended treatment sequence for my specific situation—surgery first or chemotherapy first?
3. What chemotherapy regimen do you recommend, and what are the expected side effects?
4. If my tumors shrink with chemotherapy, could I become a candidate for surgery?
5. Are there any biomarker tests (like HER2 status or microsatellite instability) that might guide targeted therapy options?

Supporting Your Treatment

According to NCCN Guidelines, a multidisciplinary team approach is essential—this means your care should involve surgical oncologists, medical oncologists, and potentially interventional radiologists working together to determine the best approach for YOUR specific situation.
