Intraperitoneal chemotherapy after surgery for gastrointestinal stromal sarcomas reduces peritoneal recurrence but does not prevent liver metastases. Treating primary disease may improve survival.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastrointestinal Oncology

Background:

  • Gastrointestinal stromal sarcomas (GISTs) commonly spread within the abdomen.
  • Standard treatments like surgery and chemotherapy often fail to prevent recurrence and liver metastases.
  • High rates of intraperitoneal sarcomatosis and hepatic metastases lead to poor patient survival.

Purpose of the Study:

  • To evaluate the efficacy of intraperitoneal chemotherapy in managing gastrointestinal stromal sarcomas.
  • To determine if intraperitoneal chemotherapy can reduce peritoneal recurrence and improve survival.
  • To investigate the impact of treating primary versus recurrent disease.

Main Methods:

  • Review of treatment protocols involving aggressive surgical resection and postoperative intraperitoneal chemotherapy.

  • Comparison of outcomes between patients receiving surgical resection alone versus those with adjuvant intraperitoneal chemotherapy.
  • Analysis of recurrence patterns, focusing on peritoneal dissemination and hepatic metastases.

    • Main Results:

    • Postoperative intraperitoneal chemotherapy significantly lowered the peritoneal recurrence rate in recurrent GISTs compared to surgery alone.
    • This approach was ineffective in preventing the development of hepatic metastases.
    • Overall survival benefit was limited due to the inability to control liver metastases.

    Conclusions:

    • Intraperitoneal chemotherapy is effective in reducing peritoneal recurrence of gastrointestinal stromal sarcomas.
    • Current intraperitoneal chemotherapy strategies do not prevent hepatic metastases, limiting impact on overall survival.
    • Treating primary GISTs with this approach may offer a better chance to decrease peritoneal recurrences and improve survival.
