First-line treatment in advanced or metastatic disease: one size fits all or adapted to specific histiotypes?

This article evaluates the supporting evidence for adapting choice of first-line chemotherapy to specific histological subtypes in advanced or metastatic soft tissue sarcoma (STS). Recent findings: The evidence for the current standard of care for first-line chemotherapy in STS is reviewed. This is followed by an overview of the evidence for use of specific chemotherapy drugs in a number of specific STS histological subtypes. The more recent literature on newer drugs being used in the first-line setting in STS is then reviewed, and finally an assessment is made as to whether it is possible at this time to tailor first-line chemotherapy to histiotype. Summary: The review shows that at present there is insufficient evidence to support the concept of adapting choice of first-line chemotherapy in advanced or metastatic STS to specific histiotypes.

ConclusionConcurrent radiation therapy and sunitinib leads to diverging results of prognostic gene array testing in a  relevant proportion of sarcoma patients. These changes may reflect tumor heterogeneity, local treatment effects, or prognostic changes of the disease. Caution is advised in the selection of samples and interpretation of test results.

This report presents an ELS case of a female infant, who was 2 months old when initially diagnosed, with the clinical stage of IIIA (G2T2N0M0). Histologic findings revealed an undifferentiated neoplasm composed of small round tumor cells with round, open chromatic nuclei, and scant cytoplasm in a sheet growth pattern. Fluorescence in situ hybridization (FISH) analysis showed absence of EWSR1 and ETV6 gene rearrangement. Molecular genetic testing found no established variants of clinical significance but variants of unknown significance in APC, KMT2D, and MSH6 were detected. Immunostaining revealed that the tumor cells were...

Conclusion: This is the first population-level study reporting of 7 different STS treatment regimens in a country with universal and centralized healthcare. Radiation therapy for local disease control and chemotherapy for Stage 4 patients have recently become more utilized. Survival from STS is highly dependent on stage at presentation. Other population-based studies from other countries are needed to establish the current international treatment patterns. PMID: 31636505 [PubMed]

Synovial Sarcomas (SS) are a type of Soft Tissue Sarcoma (STS) and represent 8–10% of all STS cases. Although SS can arise at any age, it typically affects younger individuals aged 15–35 and is therefore part of both pediatric and adult clinical practices. SS occurs primarily in the limbs, often near joints, but can present anywhere. It is characterized by the recurrent pathognomonic chromosomal translocation t(X;18)(p11.2;q11.2) that most frequently fuses SSX1 or SSX2 genes with SS18. This leads to the expression of the SS18-SSX fusion protein, which causes disturbances in several interacting multiprotein comp...

Malignant peripheral nerve sheath tumors (MPNSTs) are soft tissue sarcomas that arise from peripheral nerve fibers and primarily occur in the setting of neurofibromatosis (NF1). MPNST arising from the penis is very rare and may require mutilating surgery to achieve surgical cure. We previously reported a case of MPSNT involving the penis in a 14-month old boy treated with neoadjuvant chemotherapy, total penectomy and adjuvant radiation. Here we report intermediate follow-up of the same patient, describe his subsequent genitourinary reconstruction, and discuss management dilemmas that arise following treatment of penile MPNST.

Objectives: The aim of this study was to analyze patterns of care in elderly soft tissue sarcoma (STS) patients and their impact on clinical outcome and treatment-related toxicity. Materials and Methods: We retrospectively collected data of>65-year-old patients diagnosed with locally advanced STS between 1991 and 2017 in a single institution. Results: The study included 111 patients: 105 (94.6%) patients underwent surgery, associated with preoperative (n=19, 17.1%) or postoperative radiotherapy (n=72, 64.8%). Anthracycline-based chemotherapy was prescribed in 41.4% of patients (n=46). Acute grade ≥3 postopera...

Conclusion: CD56–CAR-T cell therapy is a safe and effective approach and may be an option for children with solid tumors who are nonresponsive to conventional radiotherapy and chemotherapy, or are unsuitable for hematopoietic stem cell transplantation.

AbstractBackgroundRare cancers have had a challenge in establishing standard therapies for patients compared to major cancers, due to the lack of basis for clinical studies and investigations. We started a biomarker driven basket/umbrella trial using a “master protocol”, called the MASTER KEY Project, which aims to find more efficient ways to evaluate treatments for rare cancers.MethodsThe project opened in April 2017 and consists of a prospective registry study part and a multiple clinical trials part. Patients with advanced rare cancers (annual incidence
