Retinoblastoma (RB), a malignant neoplasm, is the most common pediatric intraocular tumor worldwide. With the advent of intra-arterial chemotherapy, interventional surgeons have assumed a central role in the treatment of this pediatric disease. Intra-arterial chemotherapy is a new treatment modality for RB in which chemotherapeutic agents are precisely delivered into the ocular artery, minimizing systemic toxicity. This procedure has shown impressive results and has significantly reduced the rate of enucleation in advanced and refractory RB. However, the procedure entails potentially serious acute respiratory and hemodynamic disturbances.Purpose of the study – present our experience with and features of anesthesia management in the development of life-threatening conditions during superselective intraarterial chemotherapy (SIAC) in two patients with RB.Materials and methods. We present clinical cases in 2 2-year-old patients with RB who received three courses of SIAC for RB with development of severe trigeminocardial reaction.Conclusion. SIAC is one of the new promising treatments for RB. Prominent cardiorespiratory complications are frequently observed during general anesthesia for repeated sessions of SIAC and can be potentially life-threatening. Presumably, these complications represent an autonomic reflex response to ocular catheterization. Therefore, all patients with RB who are scheduled for SIAC should be included in the high-risk group. The timing of occurrence of the trigeminocardiac reflex is predictable and temporary, but the anesthesiologist must be prepared to treat the developed complication with the help of emergency drugs (adrenaline).","PeriodicalId":52396,"journal":{"name":"Russian Journal of Pediatric Hematology and Oncology","volume":"86 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139206634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hereditary disorders in the DNA repair system can lead to the development of malignant neoplasms in childhood. DNA constitutional mismatch repair deficiency syndrome (CMMRD) is a very rare genetic autosomal recessive disorder caused by homozygous mutations in one of the four mismatch repair genes (MLH1, MSH2, MSH6, and PMS2). The frequency of occurrence is 0.0000001 of the adult and child population. For now about 150 observations have been published in the world literature. The prognosis for CMMRD syndrome is extremely unfavorable. The spectrum of tumors that make up the CMMRD syndrome is very wide, and includes mainly malignant brain tumors, tumors of the digestive tract, hematological malignancies, embryonic tumors, all of which develop in childhood.The purpose of the study is to report a case of CMMRD-associated embryonic rhabdomyosarcoma in a 3-year-old child.Conclusions. A review of the literature and the clinical case we have described show that rhabdomyosarcoma belongs to the tumor spectrum of the CMMRD syndrome. An immunohistochemical study revealed an isolated loss of PMS2 gene expression. Taking into account the clinical course of the CMMRD syndrome, a thorough study of the family history in patients with rhabdomyosarcoma is recommended, as well as a molecular genetic study, including the search for germinal mutations in genes in the DNA repair system and the assessment of microsatellite instability in the material of the tumor tissue. The clinical symptoms of CMMRD syndrome are nonspecific and depend on the morphological variant of the primary tumor. Distinctive molecular genetic features of this syndrome are: homozygous mutations with loss of function of the germline genes of the MMR system (mismatch repair) (MLH1, MSH2, MSH6 or PMS2).","PeriodicalId":52396,"journal":{"name":"Russian Journal of Pediatric Hematology and Oncology","volume":"32 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139206116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This molecular group is characterized by a favorable prognosis. Given the aggressive treatment regimens for MB, reducing the intensity of therapy for prognostically favorable tumors seems justified. Purpose of the study – to demonstrate the results of treatment of children with MB-WNT and to determine the impact on survival of various prognostic factors. The study included 85 patients with MB-WNT under the age of 18 who received treatment and were followed up from 1993 to 2022. Median age at diagnosis was 10 years (min – 3, max – 17). All patients had classical MB. Metastatic spread of the tumor at the time of diagnosis was detected in 18 (21.2 %) patients, the presence of a residual tumor according to postoperative magnetic resonance imaging – in 32 (37.7 %). Somatic mutations in the TP53 gene were detected in 10 (7.1 %) patients, in the CTNNB1 gene – in 79 (92.9 %), in the APC gene – in 5 (5.9 %), chromosome 6 monosomy – in 76 (89.4 %) children. At the time of the analysis, 74 (87.1 %) patients were alive, 11 (12.9 %) patients died, a relapse was diagnosed in 6 (7.1 %) patients, of which 5 died from disease progression, 1 patient is alive in the second remission. One patient in long-term remission developed secondary meningioma 20 years after the diagnosis of MB. The 10-year progression-free survival (PFS) was 0.92. 5-year overall survival (OS) was 0.90, 10-year – 0.86. The median OS is 112 months. When analyzing the sample of patients with MB-WNT in our study, PFS and OS were statistically significantly higher in girls without metastatic tumor spread, with total resection of the tumor, stratified into the low-risk group, and in the absence of a somatic mutation in the TP53 gene in the tumor tissue.

This study aims to describe the incidence and characteristics of COVID-19 infection in children with cancer in Armenia.Methods. A prospective analysis was conducted on PCR-confirmed cases of COVID-19 infection in children with cancer aged 0–18 years from 2020 to 2022 at the Pediatric Cancer and Blood Disorders Center of Armenia, Yeolyan Hematology Center, the only pediatric hematology/ oncology institution in our country.Results. Between June 2020 and March 2022, we studied 201 children with cancer in Armenia, of whom 35 cases of COVID-19 infection were confirmed. The median age was 8.4, and the male/female ratio was 1.3. Among the COVID-19-positive patients, 15 had acute lymphoblastic leukemia, 5 had lymphomas, 4 patients had neuroblastoma, and 2 each had medulloblastoma, rhabdomyosarcoma and Ewing sarcoma. There were single cases of osteosarcoma, acute myeloid leukemia and malignant triton tumor. Twenty patients (57 %) were asymptomatic, and the rest presented with fever, sore throat, and cough.

A survey was conducted on the attitudes towards vaccination among one thousand nine hundred thirty nine respondents including 485 doctors of various specialties (163 pediatricians, 86 surgeons, 85 obstetricians-gynecologists, 76 neurologists, 75 neonatologists), 117 nurses, 295 parents, 1042 students. The significance of differences was assessed using Student’s t-test. \u0000Results. An insufficient level of adherence to vaccine prophylaxis has been established: 43.1% of parents vaccinate their children selectively, 35.4% according to the national calendar, 17.1% refuse categorically, and 4.4% have a medical refusal. The main reason for refusal is fear of complications (30%). Less than half receive information from health workers (45.6%), the main source being the media (49.1%). Among health workers, adherence to vaccine prophylaxis is highest among pediatricians (86.1%), significantly lower among neurologists (35.6%), surgeons (43.7%), obstetricians-gynecologists (62.6%), nurses (79.5%). The main reason for distrust of vaccination is fear of post-vaccination complications, narrow specialists more often choose the answer “better to get sick”. Among medical university students there is a significantly higher adherence among senior students in paediatrics (63.6%) compared to students in undergraduate (40.8%) and medical school (48.8%).
