Until recently, TFs were considered to be an “undruggable” class of proteins due to an absence of deep hydrophobic pockets, large protein-protein interaction interfaces, and nuclear localization (82). In FP ARMS, PAX-FOXO1 orchestrates the formation of super-enhancers, which drive the transcription of core regulatory TFs in a strong autoregulatory loop. doi: 10.1158/1078-0432.CCR-15-0491, 171. (2012) 21:1012–8. As whole-genome and transcriptome sequencing of rhabdomyosarcoma tumors has revealed, the genomic diversity of this disease requires a personalized (genotype-guided) approach to therapy. The authors show that BRD4 small molecule inhibitor, JQ1 selectively disrupts the interaction between BRD4 and PAX3-FOXO1, leading to rapid degradation of the fusion gene and abrogation of transcriptional output (89).

A small subpopulation of drug-resistant tumor cells (harboring a genetic alteration conferring a survival advantage) present at initial treatment may persist and expand, resulting in eventual failure to eliminate residual tumor mass. Alveolar rhabdomyosarcoma tends to grow faster than embryonal rhabdomyosarcoma and usually requires more intense treatment. doi: 10.1038/nchembio.1858, 87. RMS is historically classified based on histopathologic features into distinct clinical subtypes— embryonal RMS (ERMS), alveolar RMS (ARMS), pleomorphic, and spindle cell and sclerosing RMS (ssRMS) (4, 5). Other soft tissue sarcomas in children and adults have also been responsive to this type of therapy.

Among the five structurally diverse BET bromodomain inhibitors tested in this study, OTX015 was reported to be most potent across a range of FP RMS cell lines, but its clinical efficacy has not been evaluated. Other phosphorylation sites are known to control the transcriptional activity of PAX3-FOXO1, including the residues S201 (phosphorylated by the kinase GSK3β) (103), S205/S209 (by CK2) (104), and S430 (by CDK4) (105). Because the Bcl-2 family of antiapoptotic proteins is required for cancer cell survival, inhibiting its function is one potential therapeutic approach. Chemical genomics reveals histone deacetylases are required for core regulatory transcription.

Hata AN, Niederst MJ, Archibald HL, Gomez-Caraballo M, Siddiqui FM, Mulvey HE, et al. The relationship between Hh signaling dysregulation and RMS has subsequently been supported by several studies (115–118). The treatments for rhabdomyosarcomas include surgery, chemotherapy or radiotherapy, or a combination of all three. PAX-FOXO1 fusion status drives unfavorable outcome for children with rhabdomyosarcoma: a children's oncology group report. The receptor tyrosine kinase, FGFR4 is frequently mutated and/or overactivated in RMS tumors, and recent work has implicated the role of FGF signaling in the evasion of apoptosis (109).

Adult rhabdomyosarcoma survival improved with treatment on multimodality protocols Int J Radiat Oncol Biol Phys . Embryonal rhabdomyosarcoma (RMS) of the cervix is a rare entity, encountered mainly in the first two decades of life. A rhabdomyosarcoma is a type of soft tissue sarcoma. Treatment in patients with rhabdomyosarcoma (RMS) involves a combination of surgery, chemotherapy, and radiation therapy. Below, we summarize the key preclinical and clinical findings on novel targeted therapy and immunotherapy options in RMS (Figure 2). Intensity-modulated radiotherapy with use of cone-down boost for pediatric head-and-neck rhabdomyosarcoma. Author information: (1)Children's Hospital, Columbus, Ohio, USA. reported that positive fusion status correlated with an inferior clinical outcome, while Stegmaier et al. It often develops in the head and neck area, especially in the tissues around the eye (orbital rhabdomyosarcoma). Trends in childhood rhabdomyosarcoma incidence and survival in the United States, 1975–2005. Because funding of drug development for a rare childhood cancer such as RMS is limited, preclinical studies have focused on molecularly actionable targets that have been studied in other human cancers, many of which have clinically approved therapies.

As a result, treatment guidelines for this malignancy are not well-established. 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. Current targeted therapies and immunotherapies targets under evaluation in preclinical and/or clinical development in North America and Europe for rhabdomyosarcoma. ), conferring these tumors molecular dependencies which can be targeted by clinically available drugs (19). A recent preclinical study reported that the combination of olaparib and temozolomide (DNA-damaging agent) is a potent therapy for elimination of tumor cells in a human xenografted tumor zebrafish model of RMS. (162) conducted a small phase I study (NCT00902044) evaluating the efficacy of HER2-targeted CAR T-cell therapy in combination with lymphodepletion chemotherapy in patients with advanced HER2-positive sarcoma.

Other studies have implicated that inhibition of another epigenetic regulator, histone deacetylase (HDAC) has antitumor effects in preclinical RMS models. Independent studies have reported the ability of HDAC inhibitors, entinostat, panobinostat, and vorinostat to delay tumor growth in xenograft models of RMS (95, 96). PLOS Genetics. 162. Rhabdomyosarcoma can occur throughout childhood and may be present at birth. The understanding that inhibition of the DDR can be exploited in cancer cells to sensitize them to DNA lesions induced by chemotherapy or RT has been well-established in other cancers.

RMS is historically classified based on histopathologic features into distinct clinical subtypes— embryonal RMS (ERMS), alveolar RMS (ARMS), pleomorphic, and spindle cell and sclerosing RMS (ssRMS) (4, 5). (2001) 20:5736–46. As reviewed by DeRenzo et al., treatment of solid pediatric tumors presents a unique set of challenges that must be carefully taken into consideration. identified potaninib from a panel of five tyrosine kinase inhibitors as a potent FGFR4 inhibitor that inhibits tumor growth in a RMS mouse model (110). Pediatric cancers are characterized by dynamic chromosomal instability, which can result in loss of chromosomal segments or copy-number alterations, contributing to the genetic heterogeneity of the tumor mass. The estimated 3-year FFS rate was 89% (95% CI, 85% to 92%), and the overall survival rate was 98% (95% CI, 95% to 99%). Even the most successful targeted therapies that have been approved for the treatment of human cancers fail to completely eliminate residual disease in patients, leading to eventual relapse despite an initial response. Aberrant Hh signaling can be attributed to various germline mutations— loss of chromosomal region 9q22 containing PTCH in 33% of ERMS tumors (119, 120), loss of SUFU in 18% ERMS tumors (121), and/or genomic amplification of 12q13-15 containing the GLI1 gene in a small subset of ARMS tumors (116). The first step would be to identify ligands capable of binding PAX-FOXO1 with sufficient specificity and affinity. doi: 10.1016/bs.acr.2018.02.006, 98. Targeting hedgehog signaling reduces self-renewal in embryonal rhabdomyosarcoma. One study reported that Smac mimetics sensitized two RMS cell lines toward natural killer (NK) cell-mediated killing in an apoptotic-dependent manner (146). Sensitivity to poly(ADP-ribose) polymerase (PARP) inhibition identifies ubiquitin-specific peptidase 11 (USP11) as a regulator of DNA double-strand break repair. Dev Cell.

Effective surgical excision is challenging in cases of rhabdomyosarcoma of the head and neck region owing to involvement of 18 For patients diagnosed with metastatic rhabdomyosarcoma, insufficient local therapy options and incomplete eradication of occult microscopic residual disease are the most common causes of treatment failure (176). Rhabdomyosarcoma is a rare and sometimes deadly cancer that affects children. p. 183–211. Importantly, the knowledge that FP RMS cells are selectively dependent on epigenetic readers, writers, and erasers of the histone acetylation-axis can be exploited in the pharmacological disruption of these complexes (90). Phase I clinical trial of ipilimumab in pediatric patients with advanced solid tumors. This is the most common type and has a predilection for the head, neck and the genitourinary tract.
