Abstract

Background Post-chemotherapy febrile neutropenia results in high morbidity and mortality in children with malignancy. Many prognostic factors, such as microorganism patterns, as well as the use of antibiotics and antifungals can affect the outcomes. However, limited study is available in Indonesia. Objective To determine the microbial profiles, antibiotic sensitivity, and other factors that influence mortality from febrile neutropenia in pediatric malignancies with infections. Methods This retrospective cohort and descriptive study of 180 children with 252 episodes of neutropenic fever was done in Cipto Mangunkusumo Hospital, Jakarta, between 2015 and 2017. Medical history of possible predictive prognostic factors, including microorganism patterns and antibiotic sensitivity, were recorded. Prognostic factors were analyzed using multivariate logistic regression tests. Results The most common bacteria was Gram-negative (54.5%), while Candida sp. was the most common fungal infection (82.5%). Klebsiella sp. was mainly sensitive to amikacin (85.71%), while Pseudomonas aeruginosa was sensitive to ceftazidime (75%), as well as amikacin and gentamicin (100% sensitivity in combination). Staphylococcus sp. was mainly sensitive to amoxi-clav and ampi-sulbactam (76.9%). Almost all fungal groups were susceptible to fluconazole, ketoconazole, voriconazole (80-100%). Prognostic factors that increased mortality risk were central venous cannulation (RR 1.947; 95%CI 1.114 to 3.402), wasting (RR 1.176; 95%CI 1.044 to 1.325), severe wasting (RR 1.241; 95%CI 0.975 to 1.579), and hematologic malignancies (RR 0.87; 95%CI 0.788 to 0.976). Conclusion Central venous cannulation and wasting are significant prognostic factors of increased mortality in children with febrile neutropenia. Gram negative bacteria along with Candida sp. is the most common pathogen in such condition.

Abstract

Background Over the years, the survival rate of children with osteosarcoma has increased with improved management. However, survival tends to be lower in low-middle-income countries. Objective To report the survival rate of children with osteosarcoma in a single center in Indonesia and to evaluate the outcomes of treatment modalities currently used. Methods We performed a retrospective analysis of the medical records of pediatric osteosarcoma patients in Cipto Mangunkusumo Hospital from 2015 to 2019. Patients were categorized based on age group, sex, primary tumor location, treatment modalities, disease metastasis, and disease outcome. Results We included 83 children with osteosarcoma, with an age range of 4-17 years (median 13 years). Mean estimated overall survival and event-free survival were 28 (95%CI 24 to 32) months and 10 (95%CI 8 to 13) months, respectively. Overall survival duration between treatment modality groups was significantly different (P<0.05). The mean estimated overall duration of survival was 9 (95%CI 3 to 15) months for chemotherapy, 18 (95%CI 14 to 22) months for chemotherapy with surgery, and 21 (95%CI 14 to 27) months for chemotherapy with surgery and radiation. Conclusion The survival rate of childhood osteosarcoma in Indonesia remains low. The current treatment option currently used in our center may contribute to the low rate of survival.

Abstract

Background Risk stratification for acute myeloid leukemia (AML) in children is a must in treatment strategy. This stratification is based on cytogenetic profiles, which are needed to determine proper management to gain better outcomes and reduce side effects of treatment. There is no such risk stratification available in Indonesia until now. Objective To evaluate the association between cytogenetic profiles of t(8,21) and inv(16) mutations with the complete response to induction phase of chemotherapy in pediatric AML. Methods A prospective study was conducted between year 2018 and 2020, involving children with AML from 4 pediatric oncology centers in Jakarta. Subjects were evaluated for cytogenetic profiles, especially t(8,21) and inv(16), as the favorable predictors for AML. Bone marrow remission was evaluated after 2 cycles of induction phase. The results were evaluated for remission rate and survival analysis. Results Karyotype data of 18 subjects were obtained. Translocation t(8;21) detected in 1 subject, and inv(16) mutation in 4 subjects. These two variables had no significant correlation with complete remission after induction phase. Nevertheless, favorable group had more tendencies to achieved remission than unfavorable group. Complete remission achieved in 61% subjects, 90% of theme had a relapse period with an average time 43 weeks. The relapse period in favorable group was shoter than in unfavorable group (34 weeks and 44 weeks, respectively). Conclusions This study shows that cytogenetic profiles of t(8;21) and inv(16) mutation can not be used as prognostic factors for complete remission after induction phase of chemotherapy in pediatric AML.

Abstract

Langerhans cell histiocytosis (LCH) is a rare disorder characterized by abnormal clonal proliferation of Langerhans dendritic cells. The incidence of LCH is 1 to 3 cases per 1 million children worldwide, and occurs most frequently in children of 1–4 years of age. The etiopathogenesis of LCH, whether it is neoplastic or reactive, is still controversial. Langerhans cell histiocytosis has a wide spectrum of clinical features, and dermatological abnormalities usually occur early. The most frequent lesions are elevated yellowish-red translucent papules about 1–2 mm in diameter and generally located in seborrheic areas. The most recent classification (the Histiocyte Society study 2017) categorized LCH into four groups; a single system with involvement of unifocal or multifocal organs, lung LCH, and multi-system LCH with either low- or high-risk multiorgan involvement. The definitive diagnosis of LCH are typical morphology along with Birbeck granules and/or positive results on CD1a antigen stain on cells found on lesions. Treatment of LCH is multimodal, determined based on age, extent of lesion, organ involvement, and organ location.
