[Recent strategies in the chemoterapy of soft tissue tumors]

PÁPAI Zsuzsanna, KISS Nóra

[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.]

[The indication for surgical resection in secondary liver malignancies - New therapeutic approaches]

LUKOVICH Péter, PŐCZE Balázs

[During the last decade liver surgery underwent major improvement: mortality rates reduced meanwhile new surgical approaches converted surgeons’ consideration on many advanced cases likely to be resectable. Liver is the most frequent site for tumor metastases and liver metastasis surgery experienced major changes as well. As long as liver resection related mortality rates have decreased indication for operative treatment of liver metastasis with certain primary tumors (stomach, pancreas) gained reconsideration and became reasonable. New surgical methods and approaches (laparoscopy, portal vein embolization) came into everyday application meantime several researches were completed enabling oncological aspect interpretation. Laparoscopy is a proven rational way of approach not only in cases of primary but metastatic liver tumors too: short and long term survival rates and oncological results are comparable with the results of open surgery. Although reports on large number series have not yet been published, it seems that practice of laparoscopy can bring increased number of cases where resection of primary tumor and synchronous liver metastasis can be performed simultaneously. Treatment strategies including surgical procedure overwhelm results of schemes planned with chemotherapy lines only even for patients suffering from advanced metastatic disease with necessary extended liver resection together with major vessel resection or for those who require liver resection following portal occlusion method. Consent opinion in best therapeutic option by oncologist and surgeon is essential to reach optimal liver metastasis patient treatment.]
