The treatment of GIST tumors is complex and requires the collaboration of various medical disciplines (surgery, gastroenterology, oncology, radiation therapy, radiology, etc.). In order to optimally treat GIST disease, surgical and medical treatments are primarily used.
As a GIST center, we can offer you the entire spectrum of GIST diagnostics and therapy from a single source. Our range of therapies is also rounded off with the option of taking part in studies.
Surgical therapy
The treatment of choice is surgical tumor removal. The success of an operation depends heavily on the size and location of the tumor.
If complete tumor removal seems questionable due to the size or location of the tumor, it should first be clarified whether preventative therapy with imatinib can be carried out to shrink the tumor. The knowledge is gained from a mutation analysis of the tumor tissue. Depending on the type of tumor, prior therapy makes sense.
Medical therapy
A GIST can be treated with medication. Therapy can be used neoadjuvantly (before surgery), adjuvantly (after surgery) or palliatively (to relieve symptoms).
Before surgical tumor removal, the therapy aims to shrink the tumor and thus simplify the subsequent operation. After a tumor has been surgically removed, the aim of therapy is to kill the residual tumor cells that may still be in the body and are not visible to the eye, thereby reducing the risk of recurrence.
Drug therapy uses substances that act as specifically as possible on specific cancer cells and kill them or inhibit their growth. Depending on the type of GIST, drug therapy may be an option. If the tumor disease is already advanced or the primary tumor is inoperable, the focus is on maintaining quality of life and extending survival through drug therapy.
Local treatment procedures
For symptomatic GISTs, additional local treatment procedures can be discussed. For example, operations, radiofrequency ablation (RFA), microwave ablation (MWA), transarterial embolization (TAE) and/or selective internal radiotherapy (SIRT) can be considered as therapeutic methods. The selection of suitable patients can only take place through interdisciplinary discussion.
