[Conventional adjuvant therapy is, in most cases, either the well-known standard doxorubicin monotherapy or the combination of doxorubicin + ifosfamide. No clear guideline has been developed yet - adjuvant therapy is recommended in cases with high grade, larger than 10 cm, sarcoma, where surgery hasn’t been suffi ciently radical, and adjuvant radiotherapy may not be advisable. In locally advanced tumors, due to the requirements of limb salvage, isolated limb perfusion is recommended. As a new compound, hafnium-oxide nanoparticles (NBTXR3) can be useful in local therapy: combining intratumoral injection and radiotherapy may be a fl agship initiative, however further investigations are necessary. In the treatment of metastatic tumors, beside the standard methods, new, targeted treatments are becoming more and more prevalent: in leiomyosarcomas trabectedine, pazopanib and olaratumab; in liposarcomas trabectedine and eribulin; in synovial sarcomas pazopanib; and in imatinib-resistant GIST, sunitinib and regorafenib. Soft tissue sarcomas are rare tumors categorized as heterogeneous histological subtypes. In their treatment, it is key to customize the treatment based on these subtypes and interdisciplinary collaboration with the orthopedic surgeon, the pathologist and the radiotherapist to determine the suitable therapy for each individual.]
