Abstract
Aim: Atypical teratoid rhabdoid tumor (ATRT) is a rare and highly aggressive primary CNS neoplasm, predominantly observed in children. The use of autologous stem cell transplantation (ASCT) in pediatric ATRT has shown promise; however, its utility in adult ATRT remains unclear. Patients & methods: This study presents the case of an adult patient with ATRT who is in remission after ASCT and reviews the literature on ASCT in adults with ATRT. Four cases of ATRT in adults who underwent ASCT were identified, with pertinent data summarized. Results: All five patients survived longer than the historical average survival rate, four of whom had no clinical or radiographic evidence of disease at the final follow-up. Conclusion: Based on limited data, there may be a role for ASCT in the treatment of adults with ATRT.

Abstract
OBJECTIVE Malignant rhabdoid tumor (MRT) is a highly aggressive tumor that occurs mostly in young children with extremely poor prognosis. Standardized and effective treatment strategies for MRT have yet to be established because of its rarity. Here, we report our single-institutional experience involving MRT treatment. METHODS Patients with newly diagnosed MRT between March 2016 and October 2021 were included. The clinical characteristic, treatment-related toxicities, clinical outcomes, and prognostic factor were retrospectively analyzed. RESULTS A total of 18 patients with MRT were enrolled during the 5 years. The median age was 42.8 months (range 10 to 82 years). Among the 18 patients, 9 patients died after a median of follow-up 26 months (range 3 to 42 months). The 1-year event-free survival (EFS) and 3-year overall survival (OS) rates of the entire cohort were 63% (95% CI 46% to 74%) and 67% (95% CI 49% to 82%), respectively. Univariate analysis of patients who underwent gross or total resection followed by adjuvant chemotherapy and radiotherapy demonstrated an improvement in 1-year EFS. However, only gross resection and total resection predicted a better 3-year OS. CONCLUSIONS Surgical excision is still the mainstream treatment for MRT. Postoperative adjuvant treatments including chemotherapy and radiotherapy contribute to improved disease control rate. Our single-institute experience may provide insights into the multimodal treatment of MRT.

Abstract
Peripheral blood stem cell apheresis has become a routine procedure for the collection of peripheral blood stem cells to enable high-dose chemotherapy followed by autologous stem cell transplantation in high-risk pediatric malignancies. However, the procedure remains challenging in very low-weight infants due to high extracorporeal blood volume and citrate toxicity. Our case report demonstrates in detail a successful and complication-free large-volume leukapheresis in a very small infant weighing 6 kg using a Spectra Optia apheresis system after placing a femoral double-lumen Shaldon catheter. Anticoagulation was achieved by citrate dextrose solution without the use of heparin. The total amount of blood being processed during the procedure equaled almost 4 times the total blood volume of the patient. The final apheresis product contained 14.0×10 CD34 cells/kg body weight. The infant was diagnosed with an atypical teratoid/rhabdoid tumor of the thalamus and third ventricle at the age of 3 months and had a history of epileptic seizures.

Abstract
INTRODUCTION Atypical teratoid/rhabdoid tumor (AT/RT) is an aggressive embryonal tumor of the central nervous system with a generally dismal prognosis, especially in patients younger than 12 months. DISCUSSION We here describe the unusual case of an infant with AT/RT with long-term survival despite low-cumulative dose chemotherapy after subtotal resection. Due to a poor neurological situation and an unfavorable oncological prognosis, therapy was halted after two partial surgical resections and four of the nine chemotherapy courses recommended by the European Rhabdoid Registry, without the patient receiving either radiotherapy or high-dose chemotherapy. The patient is alive without evidence of disease 52 months after diagnosis. CONCLUSION This case report highlights that independent prognostic factors are urgently needed for optimizing treatment stratification and preventing overtreatment.

Abstract
Among infant malignancies, congenital tumors, especially those of the central nervous system (CNS), constitute a rather unique subgroup. Poor survival rates (28% in CNS tumors) may be attributed to the aggressive biology as well as specific therapeutic limitations innate to the young age of affected patients. Our patient developed synchronous congenital tumors: an atypical teratoid/rhabdoid tumor (AT/RT) localized in the right lateral ventricle of the brain and a malignant rhabdoid tumor (MRT) in the soft tissue of the right orbit. A de novo germline chromosomal deletion in 22q encompassing the SMARCB1 gene was detected, prompting the diagnosis of a de novo rhabdoid tumor predisposition syndrome 1 (RTPS1). The patient was reported to the European Rhabdoid Registry (EU-RHAB) and treated according to the Rhabdoid 2007 recommendation. Despite the very young age of the patient, the initially desperate situation of RTPS1, and the synchronous localization of congenital rhabdoid tumors, intensive chemotherapy was well tolerated; the child is still in complete remission 5 years following diagnosis. In conclusion, RTPS1 with congenital synchronous MRTs is not necessarily associated with a detrimental outcome. Intensive multidrug chemotherapy, including high dose chemotherapy, may be feasible and justified.

Abstract
A retrospective analysis of data from the European Rhabdoid Registry (EU-RHAB) was performed to describe the outcome of children with atypical teratoid/rhabdoid tumors (AT/RT) who underwent high-dose chemotherapy (HDCT) with auto-SCT. Nineteen patients (male, n=15; median age at diagnosis 21 months) were identified. Nine patients presented with metastatic disease at diagnosis. A partial or subtotal resection was achieved in 11, a total resection in five and a biopsy in three patients. Patients received a median of six chemotherapy cycles prior to HDCT. Additional radiotherapy was performed in 14 patients (first-line, n=9; following progression, n=5). Six patients underwent tandem auto-SCT. Disease status before HDCT was CR in six, PR in eight, stable disease in two and progressive disease (PD) in two patients (data missing, n=1). With a median follow-up of 16 months, 14 patients progressed. Estimated progression-free and OS at 2 years were 29% (±11%) and 50% (±12%), respectively. At last follow-up, eight patients were alive (first CR, n=4; second CR, n=2; PR, n=1; PD, n=1). Eleven patients died of PD. Median time-to-progression was 14 months. Selected patients with AT/RT might benefit from HDCT with radiotherapy. The definitive impact of this treatment modality has to be evaluated prospectively in a randomized trial.

Abstract
Rhabdoid tumors are rare but highly aggressive tumors with a predilection for infants and young children. The majority of these tumors harbor biallelic mutations in SMARCB1/INI1/hSNF5. Rather rare cases with mutations in other SWI/SNF core members such as BRG1 are on record. Rhabdoid tumors have only recently been registered and treated according to specifically designed treatment recommendations and in the framework of clinical trials. Within the last decade, prognosis has improved significantly but at least 50% of patients still relapse and subsequently almost inevitably succumb to their disease. This review summarizes past and current clinical approaches and presents an overview of the rationales for targeted therapy with potential for future clinical treatment trials for rhabdoid tumors.

Abstract
OBJECTIVE This study investigated epigenetic modifications in human central nervous system atypical teratoid rhabdoid tumors (AT/RTs), in response to inhibition of insulin-like growth factor receptor 1 (IGF-1R). MATERIALS AND METHODS Tumor tissue was obtained from two pediatric patients, tissue was dissociated, and primary cultures were established. Cultured cells were treated with picropodophyllin (PPP; 0, 1, and 2 μM for 48 h), a selective IGF-1R inhibitor. Histone acetylation and methylation patterns (H3K9ac, H3K18ac, H3K4me3, H3K27me3) and levels of histone deacetylases (HDACs; HDAC1, HDAC3, and SirT1) and histone acetyl transferases (GCN5 and p300) were examined. H3K9ac and H3K18ac decreased in response to treatment with PPP. HDAC levels showed a biphasic response, increasing with 1 μM PPP, but then decreasing with 2 μM PPP. CONCLUSION Inhibition of IGF-1R modified epigenetic status in AT/RT. Determining the mechanisms behind these modifications will guide the development of novel therapeutic targets for this malignant embryonal cancer.

Abstract
PURPOSE Atypical teratoid/rhabdoid tumor (AT/RT) is an uncommon and aggressive tumor that often affects infants. Irradiation improves survival but has traditionally been avoided in patients under the age of 3 due to the increasing risk of neurocognitive side effects. We report the first cohort of AT/RT patients treated with proton therapy. METHODS AND MATERIALS All patients with AT/RT treated at Massachusetts General Hospital (MGH) Frances H. Burr Proton Beam Therapy Benter between July 2004 and November 2011 were included in this study. All patients were treated with 3-dimensional conformal proton therapy (3D-CPT). RESULTS Ten consecutive patients of a median 2.3 years of age and with a median follow-up of 27.3 months (range, 11.3-99.4 months) were identified. Two patients suffered distant relapse; 1 patient was successfully treated with involved field irradiation and chemotherapy, while the second patient died of disease. At last follow-up, 9 patients were alive without evidence of disease. Proton radiation demonstrated increasing sparing of the cerebrum, temporal lobe, cochlea, and hypothalamus. CONCLUSIONS Initial clinical outcomes with proton therapy are favorable. The advantages of proton therapy are particularly suited to the treatment of AT/RT, a tumor that often requires irradiation treatment at an age when avoiding irradiation to healthy tissues is most desirable.

Abstract
Background Atypical teratoid rhabdoid tumor (ATRT) patients display a dismal median overall survival of less than 1 year. A consistent fraction of cases carries de-novo SMARCB1/INI1 constitutional mutations in the setting of the “rhabdoid tumor predisposition syndrome” and the outcome is worst in infant syndromic ATRT patients. Case presentation We here describe a patient affected by mosaic Klinefelter syndrome and by rhabdoid tumor predisposition syndrome caused by constitutional SMARCB1/INI1 heterozygous mutation c.118C>T (Arg40X). Patient’s ATRT primary tumor occurred at 2 years of age concurrent with metastatic lesions. The patient was rendered without evidence of disease by combined surgery, high-dose poli-chemotherapy and craniospinal irradiation, followed by autologous hematopoietic stem cell transplantation. At the onset of a spinal lesion 5.5 years later, both tumors were pathologically and molecularly evaluated at the national central pathology review board and defined as ATRT in a syndromic patient, with strong evidence of a clonal origin of the two lesions. The patient was then treated according to SIOP guidelines and is now alive without evidence of disease 24 months after the detection of metastatic disease and 90 months after the original diagnosis. Conclusion The report underscores the current utility of multiple comprehensive approaches for the correct diagnosis and clinical management of patients affected by rare and atypical brain neoplasms. Successful local control of disease and achievement of long-term survival is possible in ATRT patients even in the setting of rhabdoid tumor predisposition syndrome, infant age at diagnosis and metastatic spread of disease, thus justifying the efforts for the management of this severe condition.

Abstract
BACKGROUND Currently, Atypical Teratoid Rhabdoid Tumor (AT/RT) constitutes one of the most difficult to treat malignancies in pediatrics. Hence, new knowledge of potential targets for therapeutics and the development of novel treatment approaches are urgently needed. We have evaluated the presence of cytokine pathways and the effects of two clinically available multi-tyrosine kinase inhibitors for cytotoxicity, target modulation and drug combinability against AT/RT cell lines. RESULTS AT/RT cell lines expressed measurable quantities of VEGF, FGF, PDGF and SDF-1, although the absolute amounts varied between the cell lines. The targeted receptor tyrosine kinase inhibitor sorafenib inhibited the key signaling molecule Erk, which was activated following the addition of own conditioned media, suggesting the existence of autocrine/paracrine growth stimulatory pathways. The multi-tyrosine kinase inhibitors sorafenib and sunitinib also showed significant growth inhibition of AT/RT cells and their activity was enhanced by combination with the topoisomerase inhibitor, irinotecan. The loss of cytoplasmic NF-kappa-B in response to irinotecan was diminished by sorafenib, providing evidence for a possible benefit for this drug combination. CONCLUSIONS In addition to previously described involvement of insulin like growth factor (IGF) family of cytokines, a multitude of other growth factors may contribute to the growth and survival of AT/RT cells. However, consistent with the heterogeneous nature of this tumor, quantitative and qualitative differences may exist among different tumor samples. Multi-tyrosine kinase inhibitors appear to have effective antitumor activity against all cell lines studied. In addition, the target modulation studies and drug combinability data provide the groundwork for additional studies and support the evaluation of these agents in future treatment protocols.

Abstract
Primitive malignant rhabdoid tumors of the central nervous system are rare and have a poor prognosis. Adult and adolescent cases are exceptional. We report the case of a 16-year-old girl who presented an intratumoral hemorrhage in a rhabdoid tumor. She was treated with surgery, followed by intravenous and intrathecal chemotherapy. Despite intensive treatment, she died 5 months after diagnosis. We discuss the different therapeutic options for this patient and review the literature on this kind of tumor.

Abstract
Atypical teratoid rhabdoid tumor (AT/RT) is a highly malignant embryonal CNS tumor, generally unresponsive to any form of therapy, uniformly fatal within 1 year. We report 15 cases of AT/RT diagnosed at our center over a period of 5 years (2003-08). Tumors were located in different sites of the neuraxis, posterior fossa being the most common (n = 10) followed by cerebral lobes (n = 3). There was one each at the supra sellar and cervical spinal regions, respectively. Radiologically most of the tumors were heterodense and enhancing heterogeneously. The tumors exhibited diverse histological profile that included rhabdoid and PNET areas in all cases, mesenchymal and epithelial areas in 73.3% and 53.3% cases, respectively. Necrosis was evident in all cases and one showed calcification. Tumor cells displayed a polyphenotypic immunoprofile. All cases were consistently positive for vimentin and epithelial membrane antigen and were negative for desmin. Variable positivity was seen for other markers. The number of cases positive for these were: CK (53%), SMA (60%), synaptophysin (66%), NFP (33.3%) and GFAP (85%). CK staining was prominent in epithelial areas, while PNET cells labeled prominently with synaptophysin. There was lack of INI1 expression in all cases. Follow-up was available in 46.6% of cases which revealed a uniform poor prognosis.

Abstract
A 5-month-old male with stage II malignant rhabdoid tumor of the kidney (MRTK) and a 24-month-old male with stage III MRTK were treated with surgical resection of tumors and chemotherapy of alternating ICE (ifosfamide, carboplatin, and etoposide) and VDC (vincristine, doxorubicin, and cyclophosphamide), followed by high-dose chemotherapy using etoposide, carboplatin, and melphalan with autologous hematopoietic stem cell transplantation (SCT). Two patients have been alive without any evidence of disease for 30 and 37 months after diagnosis, respectively, and require no medication. Consolidation with SCT should be further studies for selected patients with high-risk MRTK.

Abstract
Despite improving survival rates for children with cancer, a subset of patients exist with disease resistant to traditional therapies such as surgery, chemotherapy, and radiation. These patients require newer, targeted treatments used alone or in combination with more traditional approaches. Oncolytic herpes simplex virus (HSV) is one of these newer therapies that offer promise for several difficult to treat pediatric malignancies. The potential benefit of HSV therapy in pediatric solid tumors including brain tumors, neuroblastomas, and sarcomas is reviewed along with the many challenges that need to be addressed prior to moving oncolytic HSV therapy from the laboratory to the beside in the pediatric population.

Abstract
Embryonal tumors are the most common brain tumors in infants less than 36 months. Histologically characterized as undifferentiated small, round cell tumors with divergent patterns of differentiation, these include medulloblastoma, the most common form of embryonal tumor, as well as supratentorial primitive neuroectodermal tumor, medulloepithelioma, ependymoblastoma, medullomyoblastoma, melanotic medulloblastoma, and atypical teratoid/rhabdoid tumor. All are similarly aggressive and have a tendency to disseminate throughout the central nervous system. Because of efforts to avoid craniospinal irradiation in an attempt to lessen treatment-related neurotoxicity, management of these tumors in infants is unique. Outcomes remain similarly poor among all the tumor types and, therefore, identification of specific molecular targets that have prognostic and therapeutic implications is crucial. The molecular and clinical aspects of the 3 most common aggressive infantile embryonal tumors, medulloblastoma, supratentorial primitive neuroectodermal tumor, and atypical teratoid/rhabdoid tumor, are the focus of this review.
