All the patients had a clinical and para-clinical tumoral assessment. The study of survival and prognostic factors was done after a descriptive analysis. These prognostic factors were studied through uni and multivariate analysis. \u0000Results: The median age was 14.7 years and the sex ratio was 2 male to 1 female. The average time to first consultation was 4 months. Rhinological signs were the most frequent symptom for consultation (n= 41). The T3-T4 tumors accounted for 78% of patients and there was a lymph node invasion stage N2-N3 in 63% of cases. Non-metastatic patients had radiotherapy associated with chemotherapy in 97% of cases. Metastatic patients received hypofractionated radiotherapy on bone metastasis, and first-line chemotherapy followed by radiotherapy on the primitive tumor and lymph node areas in case of good response to chemotherapy ( n= 2). The mean follow-up was 94 months; 78% of these patients were alive and in complete remission, 19% were in therapeutic failure, and 16% of them had metachronous metastases. The five-year-overall survival was 95%. Hyposialia and skin dystrophy were the most frequent late complications. \u0000In univariate analyses, significant prognostic factors were cranial nerve invasion, intracranial invasion, and infra-temporal fossa invasion. In multivariate analysis, the most parsimonious model associated extension to the infratemporal fossa, endo-cranial extension, and initial therapeutic modality (treatment failures were less frequent with neoadjuvant chemotherapy (p= 0.22)). \u0000Conclusion: Treatment of nasopharyngeal carcinoma in children consists of chemotherapy and radiotherapy. Synchronous or metachronous metastases are common in this patient population. Modern radiotherapy techniques, including conformal radiotherapy with intensity modulation, are promising and could overcome toxicities in long-term survivors.","PeriodicalId":129489,"journal":{"name":"Iranian Journal of Pediatric Hematology & Oncology","volume":"9 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140737729","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}

There have studies regarding BMT on regimen containing total body irradiation (TBI) and a regimen without TBI. It is expected that TBI-based conditioning regimens provide better antitumor effects than chemotherapy regimens. The primary objective of TBI is to eradicate the recipient's bone marrow, facilitating the successful engraftment of donor bone marrow. Acute lymphoid leukemia (ALL) is the principal indication for TBI in bone marrow transplantation. Other diseases including Hodgkin’s lymphoma, chronic myeloid leukemia (CML), acute myeloid leukemia (AML), multiple myeloma (MM), etc., may benefit from TBI-based regimens; however, TBI use is associated with many side effects.The main complications of patients who underwent TBI-containing conditioning regimens in bone marrow transplantation are vomiting and nausea, with frequencies of approximately 66% and 35%, respectively. However, these events are easily managed. Acute complications include stomatitis, diarrhea, loss of appetite, temporary loss of taste, rash and asthenia. Moreover, veno-occlusive disease, interstitial pneumonitis, lung side effects, growth hormone deficiency, neurological side effects, cataracts, renal toxicity, endocrine impairments, and infertility are other complications in patients who underwent TBI-containing conditioning regimens in bone marrow transplantation.

This study examines the effects on AML cell lines of an indole chemical in its free and liposomal forms. \u0000Material and Method: In this experimental case control study, an AML-originated KG-1 cell line was cultured in RPMI 1640 medium. The cells were treated with the free and liposomal forms of an indole compound (C18H10N2F6O) at different concentrations of 20, 40, 100, 200, and 400 µg/mL after they attained the proper confluence. The cellular metabolic activity was examined by an MTT assay. The expression of BAX and BCL-2 genes was investigated by q-PCR to assess the apoptotic effect of that compound. The analysis was also done between each experimental group and the control group using t-test. P<0.05 was assumed significant. \u0000Results: Based on the MTT assay, the lethal effective dose of free indole was found to be 245.1 µg/ml and 164.8 µg/ml in 24 and 48 hours, respectively. The corresponding values for liposomal indole were 47.2 µg/ml and 40.6 µg/ml. Furthermore, treatment with free and liposomal forms of indole resulted in a decline in the expression level of the BCL-2 gene. However, in the case of the liposomal compound, this decrease was only statistically significant after 48 hours of treatment (P < 0.05). Furthermore, the expression of BAX gene increased after treatment with both free and liposomal forms of indole, but it significantly increased only after treatment with the liposomal compound (p < 0.05). \u0000Conclusion: These results suggest that an indole derivative, especially when liposomal, causes apoptosis in AML cells, hence exhibiting cytotoxic effects. To confirm the potential usefulness of this indole derivative as a therapeutic agent for inhibiting tumor progression in the setting of human malignancies, more studies on physiologically relevant models are necessary.","PeriodicalId":129489,"journal":{"name":"Iranian Journal of Pediatric Hematology & Oncology","volume":"108 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139444574","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}
