5 Metastatic Liver Lesions of a GIST

Tissue sparing approach for five metastatic liver lesions of a Gastrointestinal Stromal Tumor (GIST). All successfully treated in one continueous session. Quality Ablation was preferred over surgical resection to facilitate a speedy recovery after the intervention, offer the patient a better quality of life and preserve options for future treatment, since the patient is likely to develop more metastatic lesions over time.

Treatment: 

  • Treatment strategy: Quality Ablation or major surgical resection
  • Decision for minimally invasive intervention to preserve parenchyma for future treatment options, because patient is likely to develop more metastatic lesions over time
  • Resection in this case would mean removing several sections of the liver, which would affect the function of the liver and also result in a long hospitalization and recovery.

Result:

  • With Quality Ablation the most tissue sparing approach was chosen, to facilitate a speedy recovery, offer the patient a better quality of life and preserve options for future treatment, since the patient is likely to develop more metastatic lesions over time
