PAX7 Is a Sensitive Marker of Skeletal Muscle Differentiation in Rhabdomyosarcoma and Tumors With Rhabdomyosarcomatous Differentiation in the Female Genital Tract.

Int J Gynecol Pathol 2021 Jun 9. Epub 2021 Jun 9.

Department of Pathology, Stanford University School of Medicine, Stanford, California (J.J.W., G.W.C., T.A.L.) Department of Pathology, Surrey Memorial Hospital, Surrey, British Columbia, Canada (D.K.).

In the female genital tract, rhabdomyosarcoma may occur in "pure" form or as a heterologous constituent of a biphasic neoplasm such as carcinosarcoma or adenosarcoma. Discriminating rhabdomyosarcoma from its histologic mimics relies on confirmation of skeletal muscle differentiation by morphology or immunohistochemistry (IHC), which can be challenging to interpret in some cases owing to limited expression. PAX7, a transcription factor expressed in mammalian muscle progenitor cells, has been reported in up to 86% of soft tissue rhabdomyosarcomas by IHC. Read More

Rhabdomyosarcoma: How Advanced Molecular Methods Are Shaping the Diagnostic and Therapeutic Paradigm.

Pediatr Dev Pathol 2021 Jun 9:10935266211013621. Epub 2021 Jun 9.

Children's Hospital Los Angeles, University of Southern California Keck School of Medicine, Los Angeles, CA, USA (retired).

For the past 40 years, progress in rhabdomyosarcoma (RMS) has been focused on understanding its molecular basis and characterizing the mutations that drive its tumorigenesis and progression. Genetic predisposition to RMS has allowed discovery of key genetic pathways and driver mutations. Subclassification of RMS into embryonal (ERMS) and alveolar (ARMS) subtypes has shifted from histology to PAX-FOXO1 fusion status, and new driver mutations have been found in spindle cell RMS.

Regional air transportation of ovarian tissue for cryopreservation in a prepubertal female with cancer.

Pediatr Blood Cancer 2021 Jun 8:e29107. Epub 2021 Jun 8.

Division of Pediatric Surgery, Department of General Surgery, Naval Medical Center San Diego, San Diego, California, USA.

Ovarian tissue cryopreservation is the only fertility preservation (FP) option available to prepubescent females receiving gonadotoxic therapy, but it has limited availability. A 6-year-old female was diagnosed with high-risk rhabdomyosarcoma, and the planned treatment carried an 80% risk of ovarian failure. Her parents desired FP, but the nearest center was 500 miles away.

Enhancement of myogenic differentiation and inhibition of rhabdomyosarcoma progression by miR-28-3p and miR-193a-5p regulated by SNAIL.

Mol Ther Nucleic Acids 2021 Jun 20;24:888-904. Epub 2021 Apr 20.

Jagiellonian University Medical College, Faculty of Medicine, Institute of Pediatrics, Department of Transplantation, Wielicka 265, 30-663 Krakow, Poland.

Rhabdomyosarcoma (RMS) is a soft tissue mesenchymal tumor that affects mostly children and adolescents. It originates from the impaired myogenic differentiation of stem cells or early progenitors. SNAIL, a transcription factor that regulates epithelial-to-mesenchymal transition in tumors of epithelial origin, is also a key regulator of RMS growth, progression, and myogenic differentiation.

Durability of oncological outcomes of combination chemotherapy as a monotherapy for a select patient subset with non-metastatic non-alveolar bladder/prostate rhabdomyosarcoma.

J Pediatr Urol 2021 May 17. Epub 2021 May 17.

The Department of Urology, Mansoura Urology and Nephrology Center, Mansoura University, Mansoura, Egypt.

Introduction And Objectives: We aim to assess the long-term oncological outcomes of children with bladder/prostate rhabdomyosarcoma (B/P RMS) treated with multiagent chemotherapy as a monotherapy. We hypothesize that a highly select patient subset can be treated with multiagent chemotherapy as a monotherapy and spared the morbidity of local treatment with similar oncological outcomes.

Methods: Patients (≤21-year-old) treated for non-metastatic non-alveolar B/P RMS at a tertiary center and followed for>one year, were retrospectively reviewed. Read More

Rare Paratesticular Masses in Children.

J Indian Assoc Pediatr Surg 2021 Mar-Apr;26(2):117-119. Epub 2021 Mar 4.

Department of Pathology, All India Institute of Medical Sciences, Delhi, India.

Pediatric paratesticular mass is common in pediatric surgical practice, and they could be because of an underlying encysted hydrocele, a teratoma, or an epididymal cyst. Furthermore, a malignant lesion such as rhabdomyosarcoma should be ruled out. Rare entities, such as fibrous hamartoma of infancy and cellular angiofibroma, are rarely encountered. Read More

Correlation between oncological family history and clinical outcome in a large monocentric cohort of pediatric patients with rhabdomyosarcoma.

Int J Clin Oncol 2021 Jun 1. Epub 2021 Jun 1.

Pediatric Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Background: Rhabdomyosarcoma (RMS), an aggressive soft tissue sarcoma of the skeletal muscle generally affecting children and adolescents, shows extensive heterogeneity in histology, site and age of onset, clinical course, and prognosis. Tumorigenesis of RMS is multifactorial and genetic predisposition together with the family history of cancer may provide critical information to enhance the current knowledge and foster genetic counseling and testing.

Methods: In our study, we evaluated the possible correlation of oncological family history with clinical outcomes in a cohort of RMS 512 patients and treated at the Pediatric Oncology Unit of our Institute. Read More

Department of Pediatric Hematology/Oncology and Cell and Gene Therapy, Bambino Gesù Children's Hospital, IRCCS, 00165 Rome, Italy.

: Spindle cell rhabdomyosarcoma (S-RMS) is a rare tumor that was previously considered as an uncommon variant of embryonal RMS (ERMS) and recently reclassified as a distinct RMS subtype with NCOA2, NCOA1, and VGLL2 fusion genes. In this study, we established a cell line (S-RMS1) derived from a four-month-old boy with infantile spindle cell RMS harboring gene fusion. : Morphological and molecular characteristics of S-RMS1 were analyzed and compared with two RMS cell lines, RH30 and RD18.

Novel findings and expansion of phenotype in a mosaic RASopathy caused by somatic KRAS variants.

Am J Med Genet A 2021 May 30. Epub 2021 May 30.

Division of Genetics and Metabolism, Department of Pediatrics, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, USA.

Mosaic KRAS variants and other RASopathy genes cause oculoectodermal, encephalo-cranio-cutaneous lipomatosis, and Schimmelpenning-Feuerstein-Mims syndromes, and a spectrum of vascular malformations, overgrowth and other associated anomalies, the latter of which are only recently being characterized. We describe eight individuals in total (six unreported cases and two previously reported cases) with somatic KRAS variants and variably associated features. Given the findings of somatic overgrowth (in seven individuals) and vascular or lymphatic malformations (in eight individuals), we suggest mosaic RASopathies (mosaic KRAS variants) be considered in the differential diagnosis for individuals presenting with asymmetric overgrowth and lymphatic or vascular anomalies.

Department of Dermatology, University hospital Galway, Galway, Ireland.

Li-Fraumeni Syndrome (LFS) is a recognised cancer predisposition syndrome associated with early onset of multiple cancer types. It was first described in 1969 following the identification of two soft tissue sarcomas in five families with the index case presenting with rhabdomyosarcoma in childhood. The tumour spectrum classically includes a range of soft tissue sarcomas, bone tumours, haematological malignancies, breast cancer and adrenal cortical cancer. Read More
