Adolescent and young adult (AYA) sarcoma patients do not fare as well as their younger counterparts. A variety of factors theorized to underlie such disparate outcomes have been identified including distinct tumor and host biology. Compared to younger patients, AYA patients often develop genetically distinct tumors and are more likely to suffer characteristic therapy-related toxicities. Compounding factors faced by AYA patients include education, finances, employment, and obstacles to treatment adherence. Lack of clinical trial participation among AYA patients has slowed the establishment of optimized age-specific treatment protocols and hindered the collection of biospecimens for scientific investigation. The relative rarity of sarcomas among adult cancers may limit the familiarity of oncologists with state of the art diagnostic and therapeutic aspects of sarcomas in young adults. Among other interventions, improved enrollment on clinical trials is a critical step in addressing the challenges faced by AYA patients. Further insight into unique tumor and host biology among AYA patients is also an important need.

Targeting EYA3 in Ewing Sarcoma Retards Tumor Growth and Angiogenesis

Yuhua Wang, Ram Naresh Pandey, Kaushik Roychoudhury, David Milewski, Tanya Kalin, Sara Szabo, Joseph G. Pressey, Rashmi S. Hegde

Summary: Loss of EYA3 or pharmacologic inhibition of the EYA3 tyrosine phosphatase activity inhibits tumor growth and angiogenesis in Ewing sarcoma. EYA3 regulates VEGFA levels in Ewing tumors, promotes DNA damage repair and survival of Ewing sarcoma tumor cells. Target engagement is demonstrated in tumor tissue through elevated levels of the EYA3 substrate H2AX-pY142 upon loss of EYA3 or with Benzarone treatment.

FOXF1 is required for the oncogenic properties of PAX3-FOXO1 in rhabdomyosarcoma

David Milewski, Samriddhi Shukla, Berkley E. Gryder, Arun Pradhan, Johnny Donovan, Parvathi Sudha, Sushmitha Vallabh, Athena Pyros, Yan Xu, Artem Barski, Sara Szabo, Brian Turpin, Joseph G. Pressey, Douglas P. Millay, Javed Khan, Vladimir V. Kalinichenko, Tanya Kalin

Summary: The FOXF1 transcription factor plays a crucial role in FP-RMS tumorigenesis by regulating gene expression associated with FP-RMS gene signature. By cooperating with PAX3-FOXO1 and E-box transcription factors, FOXF1 functions downstream of PAX3-FOXO1 to promote the development of FP-RMS.

Comparison of 0.3-mSv CT to Standard-Dose CT for Detection of Lung Nodules in Children and Young Adults With Cancer

Samjhana Thapaliya, Leah A. Gilligan, Samuel L. Brady, Christopher G. Anton, Eric J. Crotty, Michael P. Nasser, James Geller, Joseph G. Pressey, Bin Zhang, Jonathan R. Dillman, Andrew T. Trout

Summary: Reduced-dose CT demonstrates over 90% of lung nodules in children and young adults with cancer, with moderate sensitivity and high specificity in nodule detection. The study suggests that CT performed at a 0.3-mSv mean effective dose has acceptable diagnostic performance and potential to reduce patient dose or expand CT utilization in this population.

Summary: A novel ARHGAP23-FER fusion was identified in a metastatic spindle-cell soft-tissue neoplasm, which exhibited a rapid and sustained metabolic response to the tyrosine kinase inhibitor lorlatinib.

Chemotherapy-induced thrombocytopenia in Ewing sarcoma: Implications and potential for romiplostim supportive care

Nawal Merjaneh, Jennifer Young, Avani Mangoli, Mallery Olsen, Bhuvana Setty, Adam Lane, Rajaram Nagarajan, Joseph G. Pressey, Brian Turpin

Summary: The study found that romiplostim may be beneficial in treating chemotherapy-induced thrombocytopenia in patients with Ewing sarcoma, with efficacy associated with higher drug doses. Radiation therapy had some impact on the occurrence of CIT, but other risk factors were not identified. Concurrent use of romiplostim with chemotherapy was found to be safe and feasible.

Comorbidity Burden in a Cohort of Adolescent and Young Adult Patients Diagnosed with Central Nervous System Tumors and Sarcomas

Margot A. Lazow, Ralph Salloum, Joseph G. Pressey

Summary: This study found that adolescent and young adult patients with central nervous system tumors or sarcomas have a high burden of baseline comorbidities, which increase with age. These comorbidities contribute to treatment-related toxicity and mortality, highlighting the need for tailored therapeutic and supportive care based on individual comorbidities.

Pediatric and Young Adult Image-Guided Percutaneous Bone Biopsy-A New Standard of Care?

Jo Cooke-Barber, Joseph G. Brungardt, Michael Sorger, Joseph G. Pressey, Brian Turpin, Rajaram Nagarajan, Sara Szabo, Joel Sorger, Neil Johnson, Roshni Dasgupta

Summary: This study aimed to evaluate the efficacy of image-guided percutaneous biopsy for pediatric patients with soft tissue and bony masses, and the role of intraoperative image guidance and diagnostic accuracy. The results showed that image-guided percutaneous biopsy is a safe and effective method for obtaining accurate tissue samples in children with soft tissue or bone tumors.

Molecularly Defined Subsets of Ewing Sarcoma Tumors Differ in Their Responses to IGF1R and WEE1 Inhibition

Upendra Kumar Soni, Yuhua Wang, Ram Naresh Pandey, Ryan Roberts, Joseph G. Pressey, Rashmi S. Hegde

Summary: This study analyzed the activation of receptor tyrosine kinase (RTK) pathway in Ewing sarcoma tumors and found that the tumors could be divided into two groups, one insensitive to IGF1R inhibition and the other sensitive to IGF1R or WEE1-targeted inhibitors. Primary and metastatic tumors also exhibited differences in IGF1R localization, replication stress levels, and inhibitor sensitivity. Combined inhibition of IGF1R and WEE1 led to tumor regression. These findings highlight the importance of using biopsy-derived predictive biomarkers at multiple stages of Ewing sarcoma disease management.
