Perioperative treatment of soft-tissue sarcoma

SummaryThe standard treatment of high-risk localized extremity and trunk soft-tissue sarcoma is wide local excision and radiation therapy, which can be delivered pre- or postoperatively. Improved care for sarcoma patients at expert centres with multidisciplinary tumour boards, specialized pathologists, surgeons, radio-oncologists, and medical oncologists, according to national or international guidelines, has improved outcomes. Yet, a  substantial number of patients will experience disease recurrence with metastatic spread and ultimately die from their disease. In many solid tumours neo/adjuvant chemotherapy has become an accepted standard treatment, whereas in soft-tissue sarcoma discussions on the use of cytotoxic therapy in l ocalized and resectable disease are ongoing. Some centres demonstrated the feasibility and now treat with concomitant neoadjuvant chemoradiotherapy as standard. Others argue that treatments should be given in the order of the accompanying evidence (surgery → radiotherapy → chemotherapy), which does not take biology of the disease into account and probably attempts to simplify complex decision making processes. It is important to enhance our ability to identify patients at highest risk of recurrence, and to generate data and develop tools to predict which patients will benefit from neo/adjuvant systemic therapy most.

Authors: Hayashi D, Shirai T, Terauchi R, Tsuchida S, Mizoshiri N, Mori Y, Arai Y, Mazda O, Kubo T Abstract Fibrosarcoma is a soft tissue sarcoma that is classified as a rare cancer. Therefore, no standard anti-tumor drug therapy has been established for fibrosarcoma. Although pristimerin (PM) has been reported to exert an anti-tumor effect on various types of cancer, no studies have examined the therapeutic effect of PM on soft tissue sarcoma. The purpose of the current study was to investigate the anti-tumor effect of PM on human fibrosarcoma cells (HT1080). The present study examined the cell viability, IC50 val...

AbstractPurposeThe aim of the study was to develop a patient-reported outcome measure for patients with sarcoma —the Sarcoma Assessment Measure (SAM).Methods and resultsThe systematic development of SAM included a three-stage, mixed-methods study using semi-structured interviews, focus groups and questionnaires, with all stages involving patients from across the United Kingdom. In-depth interviews were conducted with 121 patients (50% male; aged 13 –82; with soft tissue sarcoma (62%), bone tumours (28%) and gastrointestinal stromal tumours (10%)). Content analysis of the interview transcripts identified 1415 po...

Abstract Malignant peripheral nerve sheath tumor (MPNST) is a rare malignant soft tissue tumor that accounts for approximately 5% of all soft tissue sarcomas. This tumor originates from the peripheral nerves and occurs mainly in the limbs, head and neck, and spine. As a more aggressive tumor, it has higher recurrence and metastasis rates, and patient prognosis is poor. MPNST has a variety of histologic subtypes such as classic MPNST and epithelioid malignant peripheral nerve sheath tumors (EMPNSTs). Due to the diversity of histologic types, these tumors have a high histologic similarity to other benign and maligna...

AbstractSoft tissue sarcomas (STSs) are heterogeneous cancers associated with poor prognosis due to high rates of local recurrence and metastasis. The programmed death receptor ligand 1 (PD-L1) is expressed in several cancers. PD-L1 interacts with its receptor, PD-1, on the surface of tumor-infiltrating lymphocytes (TILs), thereby attenuating anti-cancer immune response. Immune checkpoint inhibitors targeting this interaction have been established as effective anti-cancer drugs. However, studies on the PD-L1 and PD-1 expression status in STS are commonly limited by small sample size, analysis of single STS subtypes, or lac...

This study aimed to perform a time ‐lapse analysis of tumor response in patients with STS treated with trabectedin from 2 phase II clinical trials.We examined 66 patients with translocation ‐related sarcoma registered in 2 Japanese phase II clinical trials. All patients previously received standard therapy before the administration of trabectedin at 1.2 mg/m2 every 3  weeks. Imaging evaluation was performed according to the study protocol. The sum of the maximum diameters of the target lesions was calculated and analyzed over time.Among the 66 patients, 9 (13.6%) showed partial response (PR) to trabectedin. H...
