Soft Tissue Sarcoma

2019: 

Dr. Breelyn Wilky at Univ. of Colorado Health Sciences, Denver, CO recently gave a talk on some of the research that being developed in the lab and in clinic on improving outcomes with immunotherapy in sarcomas. It’s long and pretty scientific-focused, but reviews the major immunotherapy trials for sarcomas, and talks about ideas about how to move forward. View the video here.

Cutaneous leiomyosarcoma on the trunk: An unusual presentation with an aggressive course – Case report and review of literature

  • In select sarcoma subtypes, researchers determined the disease control rate (DCR) with sorafenib plus dacarbazine. They examined patients with leiomyosarcoma (LMS), synovial sarcoma (SS), or malignant peripheral nerve sheath tumors (MPNST) with up to two previous lines of therapy and adequate hepatic, renal, and marrow function. Treatment regimen for these subjects comprised 3-week cycles of sorafenib at 400 mg oral twice daily and dacarbazine 1,000 mg/m2 intravenously (later reduced to 850 mg/m2). An 18-week DCR of 46% was documented in this study. Modest clinical activity of dacarbazine + sorafenib was evident in patients with these diagnoses. Dacarbazine + sorafenib was feasible and related to favorable disease-control rates; however, this combination also increased the potential for significant toxicity.

Larotrectinib Shows Promise for Patients With NTRK-fusion …

NTRK fusion is associated with several cancers, including infantile fibrosarcoma, which can require amputation or morbid surgery when disease is locally advanced. For this phase 1/2 trial (ClinicalTrials.gov Identifier: NCT02637687), researchers enrolled 11 patients with infantile fibrosarcoma (7 patients) or another sarcoma subtype (4 patients) to receive larotrectinib followed by surgery.
“This is very exciting, but only applies to 0.1% of sarcomas.  But, it is worth looking into more.  I have seen one sarcoma with
one NTRK fusion and it was very exciting.” – from Dr. Neeta Somaiah, MD, Sarcoma Research, Anderson Cancer Center.
