Preoperative Chemotherapy + Surgery for Sarcoma
(STRASS2 Trial)
Trial Summary
The trial protocol does not specify if you need to stop taking your current medications. However, if you have uncontrolled high blood pressure, you may need to adjust your antihypertensive medication before joining the study. It's best to discuss your current medications with the trial team.
The available research shows that using preoperative chemotherapy before surgery for sarcoma can lead to better outcomes. For example, in osteosarcoma, this approach has resulted in a 93% disease-free survival rate over a median of 20 months. This means that most patients did not show signs of the disease during this period. Additionally, preoperative chemotherapy can make surgery less invasive, allowing for limb-sparing procedures instead of more drastic surgeries. This treatment strategy also helps identify patients who might need different therapies if the initial chemotherapy isn't effective, improving overall treatment results.
12345The safety data for preoperative chemotherapy and surgery for sarcoma is limited and varies. Real-world data suggests that perioperative chemotherapy is used in high-risk, localized soft tissue sarcoma, but potential toxicity from cytotoxic chemotherapy is substantial. There is little consensus on the indications for chemotherapy in the adjuvant/neoadjuvant setting. Some studies have evaluated toxicity and survival outcomes, but the efficacy and safety remain controversial, with few prospective studies available. Adjuvant chemotherapy is standard for certain sarcoma subtypes, but not for low- and intermediate-risk disease, and the benefits for high-risk disease are not convincingly demonstrated.
