  Here is the conclusion:
  Conclusion of the study: The review of current literature led to the conclusion that we still have no reliable method to distinguish leiomyomas and leiomyosarcomas preoperatively. The studies in this field have, in most cases, retrospective design and the number of cases seems to be insufficient to achieve conclusive results. The rarity of malignant myometrial lesions is an obvious reason that explains such a situation.
  However, on the horizon, we can identify new game-changing options that have the potential to revolutionize our practice in cases of myometrial lesions.
  On one hand, there are many ambitious researchers introducing novel multi-parametric diagnostic scales, having promising performances in differentiating such lesions.
  On the other hand, the recent advancement of machine learning and artificial intelligence constitute promising novel tools that give hope that we can solve this problem completely. Nowadays, the biggest challenge for researchers and clinicians is organizing multicenter databases that include numerous cases of both LM and LMS, and using them for the development and validation of these novel tools.
  A NOTE: Dr. MITCHELL ACHEE, an LMS survivor and Radiologist, is working closely with several research clinicians at major sarcoma centers of excellence on am imaging project that holds promise to detect malignancies through special imaging which would be very helpful patients. This will be workgroup # 5 within the NLMSF-SPAEN International Research Roundtable. More to follow s this develops further.

Treatment for LMS is extrapolated from trials including both uterine (uLMS) and non-uLMS subtypes, although whether they respond similarly and have similar outcomes from treatment is not clear. We examined the molecular composition of LMS by site of origin to better inform future drug development and trial design.

• PharmaMar presents results of trabectedin & doxorubicin for first line treatment of leiomyosarcomas at ASCO 2020
• Madrid, June 1^st, 2020.- PharmaMar (MSE:PHM) has announced that the final results from the Phase II study of trabectedin in combination with doxorubicin for the treatment of patients with advanced metastatic uterine and soft tissue leiomyosarcoma have been presented in an Oral Abstract Session at the  American Society of Clinical Oncology (ASCO) Annual Meeting, that was held on May 29^th to 31^st, 2020.

  Under the title “A single-arm multicenter phase II trial of doxorubicin (Doxo) in combination with trabectedin (Trab) given as first-line treatment to patients with metastatic/advanced uterine (U-LMS) and soft tissue leiomyosarcoma (ST-LMS): Final results of the LMS-02 study” (Abstract 11506), Patricia Pautier, MD, from the Medical Oncology Department, Institut Gustave Roussy, Villejuif, France, has concluded that trabectedin in combination with doxorubicin is an effective first-line treatment for patients with leiomyosarcoma.

  The study achieved its primary and secondary endpoints, with a median Progression-Free Survival (PFS) of 10.1 months; a median Overall Survival (OS) of 34.4 months and an acceptable safety profile.

  As a reference (not comparable head-to-head studies), the most recent results of other doxorubicin combinations, such as those presented in ASCO 2019 in the “ANNOUNCE” Phase III study (doxorubicin + olaratumumab), reported a median PFS of 6.9 months, and an OS of 21.9 months (ASCO 2019 LBA3)[1].

  Patricia Pautier, MD, said: “Combination of doxorubicin and trabectedin constitutes an active first-line therapy for patients with uterine and soft tissue leiomyosarcoma. Results in overall response rate, progression free survival and now in overall survival are very encouraging.” And added: “Results of the LMS04 trial, a randomized phase-III study comparing this combination followed by trabectedin versus doxorubicin alone in 1st-line therapy in metastatic LMS are pending.”

  The result of this research provides the first validation of a targetable oncogenic kinase fusion as a driver in a subset of leiomyosarcomas. Overall, these findings suggest that some soft tissue sarcomas may harbor previously unknown kinase gene translocations, and their discovery may propel new therapeutic strategies in this treatment-refractory cancer.

  • 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.
