Careful review of how targeted therapies have been successful in clinical trials for other human malignancies [e.g., immune checkpoint blockade in metastatic melanoma (168, 169, 172, 174, 175)] and systematic analysis of clinical trials of related families of childhood cancers [e.g., PARP inhibition in Ewing's sarcoma (138)] provide valuable insight into translating these therapies into a RMS tumor context.

Rhabdomyosarcoma: an overview and nursing considerations A final report. Given the small number of patients available for enrollment in clinical trials, it is necessary to prioritize which therapeutic targets and combination therapies will have the most clinical benefit for the greatest number of patients. Unlike for localized disease, for metastatic RMS multimodal therapy frequently fails due to lack of a proper local therapy to treat metastatic sites such as the bone marrow and lungs. (2019) 145:13752. Clearly, there is a need to understand why these therapeutic agents which show promise in the pre-clinical stage fail to translate into meaningful outcomes in patients, and to identify strategies targeting resistance mechanisms hindering their clinical efficacy. This raises the possibility that the PAX-FOXO1 chimeric proteins can be leveraged as novel tumor-associated antigens in immunotherapy. Clin Cancer Res.

The gap between the observed efficacy of targeted therapies in preclinical models of RMS and the marginal improvements in patient outcomes observed in clinical trials has forced a reconsideration of our approach. The recurrent 2;13 and 1;13 translocations in FP RMS encode for the PAX3-FOXO1 and PAX7-FOXO1 chimeric transcription factors, which are uniquely expressed in malignant cells but not in normal cells.

A recent study designed a screen for epigenetic chemical probes to differentiate between super-enhancer driven transcription and constitutive transcription, revealing that the acetylation-axis is more important for the core regulatory TF circuit than the methylation-axis (90). Compared to classical mAb therapies which are less effective due to the existence of natural polymorphisms of FcR, the strategy of fine tuning the Fc domain to optimize effector cell function should be considered in mAb-based approaches for RMS. Despite the remarkable genetic and molecular differences between FP and FN RMS, the RTK/RAS/PI3K axis is commonly hijacked by both, suggesting that targeting this axis presents a more general therapeutic approach which could benefit a wide range of patients. Another retrospective study found that local treatment to all metastatic sites in stage IV RMS was associated with an improved progression-free survival (PFS) and overall survival (OS) at 5 years (71). The remaining 20% of fusion-negative ARMS tumors present a similar molecular profile and clinical outcome to the ERMS subtype (1416). 159 likes, 7 comments - Compassion & Choices (@compassionandchoices) on Instagram: ""Cancer has robbed me of a lot of power and control in my life. . (2018) 34:41126.e19. Over 90% of patients with low-risk localized disease can be cured with multi-modal therapy, but overall survival rates of patients with metastatic or recurrent disease remain dismal at 21% and 30%, respectively (21, 22). Current and classic episodes, featuring compelling true-crime mysteries, powerful documentaries and in-depth investigations. Fusion gene-negative alveolar rhabdomyosarcoma is clinically and molecularly indistinguishable from embryonal rhabdomyosarcoma. Rhabdomyosarcoma - Wikipedia Strategies to reduce radiation-related toxicities include incorporation of intensity-modulated RT (IMRT) or proton bean RT and the use of brachytherapy for specific sites e.g., bladder or vagina, both of which are assumed to reduce late toxicities (skeletal muscle/soft tissue changes, joint stiffness, skeletal growth problems, and secondary malignancy) (5356).

Several HDAC inhibitors are already approved for treatment of other cancers, but early clinical data show that HDAC inhibitors against solid tumors are far less effective than against hematological diseases, likely due to the pharmacokinetic differences in these two different tumor contexts (97). A recent publication demonstrated that liposome-protamine-siRNA (LRP) particles targeting PAX3-FOXO1 were efficiently delivered to ARMS cell lines and downregulated PAX3-FOXO1 and its target genes in vitro, leading to delayed tumor growth and inhibition of tumor initiation in ARMS xenograft models (84).

Upon activation of the mitochondrial apoptotic pathway, Smac is released into the cytosol, where it binds and neutralizes XIAPs, thereby allowing the caspase cascade to proceed. Combination therapy of both CTLA-4 and PD-L1 inhibitors have demonstrated clinical efficacy in advanced melanoma, suggesting its consideration in pediatric cancers (171, 172). Most of the data on targeting the RTK/RAS/PI3K axis in RMS comes from scattered preclinical reports, and none have demonstrated significant single agent activity in early phase clinical trials. Nat Rev Clin Oncol. doi: 10.1038/nm0598-619, 116. Results from the COG ARST0431 trial for patients with high-risk RMS found that high-dose chemotherapy (dose-compressed cycles of ifosfamide/etoposide and vincristine/doxorubicin/cyclophosphamide, irinotecan, and radiation) did not produce meaningful benefit for most patients, except for a minority of patients with embryonal histology and limited metastatic disease (restricted to lungs) (63).

At this point in time, it is unknown whether the PAX7 fusion partner or gene amplification is the main determinant of favorable outcome, but prospective tracking of fusion gene amplification in COG study ARST1431 is expected to clarify if gene amplifications contribute toward the observed difference. CNS relapse is a particular concern for RMS originating at parameningeal or paraspinal sites, given ease of access by direct extension. Danna Collette Nelson on Instagram: "To the dearest and most loving Moreover, because PAX-FOXO1 fusion protein is uniquely expressed in tumor cells but not in normal cells, it is an attractive target. There is a known link between RMS and cancer predisposition syndromes, such as Li-Frameni syndrome, neurofibromatosis, Beckwith-Wiedemann syndrome, and Costello syndrome (19).
