RESUMEN

ABSTRACT: The oral thrombopoietin receptor agonist eltrombopag has some side effects. One of them is related to bilirubin metabolism. Two patients with neuroblastoma in remission underwent stem cell transplantation with the Busulfan-melphalan regimen. Eltrombopag was started because of platelet engraftment failure. Indirect hyperbilirubinemia was detected after eltrombopag treatment. Laboratory and radiological investigations were all normal. The drugs and their side effects they used were examined. After eltombopag cutting, bilirubin levels of them returned to normal. These cases are presented to emphasize that eltrombopag can cause liver toxicity with hypertransaminesemia and hyperbilirubinemia. Drug side effects should be considered in the differential diagnosis of the patients. The significance of this case is that testing for serum aminotransferase and bilirubin levels should be monitored before and after eltrombopag use.

RESUMEN

Most cases of malignancies appear to be sporadic, but some syndromes are associated with malignancies with germline variants. Herein, a child with an unusual association of oncocytic variant adrenocortical carcinoma (ACC) and rhabdomyosarcoma (RMS) was presented. An 18-month-old-boy was admitted with virilization of the genital area, penis enlargement and erection, which had begun six months earlier. Serum total testosterone (457 ng/dL; NR <10), androstenedione (3.35 ng/mL; NR <0.5) and dehydroepiandrosterone-SO4 (206 mcg/dL; NR<35) were above the normal ranges. Right adrenal mass was detected. After adrenalectomy, histopathological examination revealed an oncocytic variant ACC. Three-month after surgery, he then presented with 6x8 cm sized swelling of the left leg. Histopathological examination revealed embryonal RMS. Testing for tumor protein (TP53) variant by DNA sequence analysis was positive; however; fluorescence in situ hybridization analysis was negative. After chemotherapy and local radiotherapy, the patient is in good condition without tumor recurrence. Only about one-third of these tumors have a variant of TP53. This status also applies to other genetic variants related to cancer. However, a significant association of malignancies strongly suggests a problem in tumor suppressor genes or new variants. Another as yet unidentified suppressor gene may also be present and effective in this locus. The occurrence of ACC as a part of a syndrome and positive family history of malignancies in patients are clinically important. These patients and their families should be scanned for genetic abnormalities. The patient with ACC should be followed-up carefully for other tumors to detect malignancy early.

RESUMEN

BACKGROUND: This report aims to discuss the mechanism of pleural and pericardial effusion related to mifamurtide which is an immunological agent used as adjuvant chemotherapy in osteosarcoma. CASE: Mifamurtide (2 mg/m < sup > 2 < /sup > ) and European and American Osteosarcoma Studies (EURAMOS) protocol were used together intravenously after complete surgical resection. No side effects occurred except for fever after the first dose. However, pleural, pericardial effusion, and splenic nodule formation began 11 months after discontinuation of mifamurtide treatment. Pleural biopsy revealed a type 4 hypersensitivity reaction. We treated the patient with 1,5 mg per day colchicine. Pericardial effusion attacks and nodules in the spleen disappeared. The patient had a mild pleural effusion attack which has not yet repeated. CONCLUSION: Mifamurtide, which activates macrophages, can also activate immunity with a stand by effect and cause a hypersensitivity reaction.

RESUMEN

AIM OF STUDY: Cardiac complications may be observed after hematopoietic stem cell transplantation (HSCT). Despite significant improvement in supportive care, HSCT may be associated with significant morbidity and mortality. In this study, the aim was to evaluate the frequency of clinically serious cardiac complications after HSCT in our patients. MATERIALS AND METHODS: This is a retrospective study. Cardiac complications were analyzed in 75 patients undergone to HSCT with physical examination, electrocardiography, echocardiography, and cardiac monitorization. RESULTS: The median age was 12 years (range 11-16) and M/F ratio was 2/3 = 0.66. There are five patients with six complications among the retrospective cohort of 75. These were pericardial effusion in three patients, and sinus bradycardia in two patients and ventricular tachycardia in one patient. The incidence of cardiac complications among 75 patients with HSCT was 6.7%. The mortality rates of patients with and without cardiac complication were 40% and 34%, and both of them with cardiac complication had pericardial effusion. However, the cardiac complication was not found statistically significant factor on survival ( P = 0.82). CONCLUSION: Poor risk factors of patients, myocarditis, pericarditis, and heart failure owing to cumulative doses of anthracycline, cyclophosphamide, cytomegalovirus infection or other infections, mediastinal irradiation, and cryopreserved stem cell product with dimethyl sulfoxide may be effective on the development of cardiac complications individually. Early intervention can prevent death related to this complication.

RESUMEN

Introducción. Las causas más frecuentes de la linfadenopatía cervical son las afecciones inflamatorias y reactivas; solo unos pocos casos representan una patología seria. El objetivo fue evaluar la relación entre los hallazgos ecográficos y el diagnóstico histopatológico. Población y métodos. Este estudio retrospectivo abarcó la linfadenopatía cervical en los menores de 20 años seguidos en nuestro centro, entre enero de 2007 y diciembre de 2016. Según los informes anatomopatológicos, se dividió a los pacientes en dos grupos: benigno y maligno. Se compararon los resultados anatomopatológicos y los hallazgos ecográficos. Resultados. Después del análisis de los resultados histopatológicos y los hallazgos ecográficos, se incluyó a 107 pacientes con linfadenopatía cervical persistente (44 casos malignos; 63, benignos). La media de edad de los grupos maligno y benigno fue de 14 ± 6,1 años y de 11,9 ± 4,8 años, respectivamente. La presencia de vascularidad hiliar fue estadísticamente significativa (p < 0,0001) en la linfadenopatía benigna, mientras que el flujo periférico y la vascularidad mixta lo fueron (p < 0,05) en la linfadenopatía maligna. No se observó una diferencia significativa en el diámetro máximo (27,3 ± 11,1 mm y 29,8 ± 12,3 mm, respectivamente), pero sí en el diámetro mínimo entre los grupos benigno y maligno (13,7 ± 7,3 mm y 18,7 ± 8,8 mm, respectivamente). Conclusiones. Este estudio sugiere que existe una relación entre los hallazgos ecográficos y de la biopsia para la diferenciación entre la linfadenopatía benigna y maligna, en especial, en el patrón vascular intraganglionar y el hilio ganglionar.


Introduction. The most common causes of cervical lymphadenopathy (LAP) are inflammatory and reactive conditions; only a small proportion have serious pathology, such as malignancy. The objective of this study was to evaluate the relationship between USG findings and histopathological diagnosis of the cervical LAP. Population and Methods. This retrospective study comprised the cases of cervical LAP in patients aged under 20 years old followed in our center between January 2007 to December 2016. Based on pathology reports, we divided the patients into two groups: benign and malignant. Pathology results and USG findings were compared. Results. After the analyze of the histopathological results and USG findings, 107 patients with persistent cervical LAP (44 malignant; 63 benign) were included in the study. Mean age of malignant and benign group were 14 ± 6.1; 11.9 ± 4.8 years, respectively. Hilar vascularity for benign LAP was highly statistically significant (P < 0.0001) and peripheral flow and mixed vascularity for malignant LAP were also statistically significant (p < 0.05). There was not a significant difference in the maximum diameter (27.3 ± 11.1 mm and 29.8 ± 12.3 mm, respectively), however, there was a significant difference in the minimum diameter between benign and malignant groups (13.7 ± 7.3 mm and 18.7 ± 8.8 mm, respectively).Conclusions. The present study suggests that there is a relationship between US and biopsy findings for the differentiation of benign from malignant LAP, especially in terms of nodal hilus and intranodal vascular pattern.

RESUMEN

INTRODUCTION: The standard of care in muscle invasive bladder cancer is radical cystectomy; however; transurethral resection (TUR) followed by external radiotherapy and systemic chemotherapy demonstrates comparable results with radical cystectomy in terms of local control and survival rates. OBJECTIVES: To evaluate our results of multimodality bladder preservation therapy (BPT) in patients who had muscle-invasive bladder cancer and were reluctant to radical cystectomy. METHODS: The retrospective analysis of twenty-three patients with stage T2 transitional cell bladder cancer that were consecutively treated with BPT was performed. Treatment strategy included radical TUR followed by 3 cycles of cisplatin, gemcitabine combination, and radiotherapy of 64 Gy as adjuvant treatment. The Kaplan-Meier survival estimates and log rank were calculated. RESULTS: Median follow-up time was 58 (15-158) months. Disease-free survival (DFS) and five year overall survival (OS) rates for 23 patients were 55.9% and 63.9%, respectively. Cancer-specific OS was 67%. There were no grade 3 or higher complications. CONCLUSIONS: Our small patient group suggests that BPT can be safely applied in selected cases with bladder cancer or in patients that refused radical cystectomy.


INTRODUCCIÓN: El estándar de tratamiento en el CVMI es la cistectomía radical, aunque la RTUv + RTP+ quimioterapia sistémica demuestra resultados comparables a la cistectomía radical en términos de control local y supervivencia global. OBJETIVOS: Evaluar nuestros resultados en terapia trimodal en cáncer de vejiga músculo-invasivo que rechazan la cistectomía radical. MÉTODOS: Análisis retrospectivo de 23 pacientes con estadio T3 TVMI tratados con preservación vesical (RTUv +3 ciclos de gemcitabina, cisplatino+ 64Gy RTP adyuvante). KM estimados y log Rank fueron calculados. RESULTADOS: La mediana de seguimiento fue de 58 meses (15-158). El intervalo libre de enfermedad y la supervivencia global a los 5 anos fue de 56% y 64%, respectivamente. La Supervivencia cáncer especifica fue de 67%. No se objetivaron complicaciones grado 3 o más. CONCLUSIONES: Nuestra serie de tratamiento preservación vesical demuestra que el uso de este tratamiento en pacientes debidamente seleccionados que no quieren cistectomía radical es apropiado.

RESUMEN

Posterior reversible encephalopathy syndrome (PRES) is an uncommon clinicoradiological syndrome that is characterized by acute neurological symptoms such as headache, convulsion, visual disturbance, and altered consciousness. The characteristic magnetic resonance (MR) finding is vasogenic edema, predominantly in the subcortical areas of the posterior parietal and occipital lobes on T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequences. Herein, we described a rare case of PRES induced by cyclosporine (CsA) after an allogeneic hematopoietic stem cell transplantation (HSCT) from a sibling donor.

RESUMEN

Pediatric glioblastoma multiforme is an uncommon and highly mortal brain cancer. New therapeutic treatments are being intensively investigated by researchers in order to extend the survival of patients. The immune checkpoint inhibitor nivolumab in the treatment of pediatric glioblastoma multiforme is currently under review; it is a human immunoglobulin G4 monoclonal antibody that works against the programmed cell death protein 1 receptor, designed to enhance an immunologic reaction against cancer cells. Herein, we describe the first report of a bilateral optic neuritis induced by nivolumab in a grade 4 glioblastoma multiforme patient.

RESUMEN

OBJECTIVE: Primary testicular lymphoma (PTL) is a form of extra-nodal lymphoma originating from the testicles. Currently, positron emission tomography (PET) with glucose analogue 18F-fluorodeoxyglucose (18F-FDG) is the most popular and widely used modality for evaluating tumor metabolism, and PTL usually displays increased 18F-FDG uptake. Despite the rapid increase in clinical applications of FDG PET/ computed tomography (CT), its role in PTL has neither been clearly defined nor reviewed systematically. This study reviews the usefulness and limitation of FDG PET/CT in the diagnosis and treatment of PTL. METHODS: This study included 12 patients with PTL between 2004 and 2015. We retrospectively examined PET/CT results along with patient outcome. The maximum standardized uptake value (SUVmax) was calculated. RESULTS: The mean overall survival (OS) and disease-free survival (DFS) was 44.5 months and 35.5 months, respectively. The mean SUVmax was identified as 18.5 in recurrent/metastatic group. The 1-year and 3-year OS was 94% and 69%, while the 1-year and 2-year DFS was 93.5% and 56%, respectively. CONCLUSION: FDG PET/CT is very helpful in both staging and evaluating treatment response. Although it is not a perfect tool in the initial diagnosis, it might aid in the differential diagnosis of challenging testicular tumors. Pre-treatment and post-treatment FDG uptake values may also have a prognostic value in patients with PTL.

RESUMEN

We examined outcomes of 62 pediatric patients with relapsed or refractory non-Hodgkin lymphoma (rr-NHL) who underwent hematopoietic stem cell transplantation (HSCT). The overall survival (OS) and event-free survival (EFS) rates were 65% and 48%, respectively. Survival rates for patients with chemosensitive disease at the time of HSCT were significantly higher than those of patients with chemoresistant disease (69% vs. 37%, p = .019 for OS; 54% vs. 12%, p < .001 for EFS; respectively). A chemoresistant disease at transplantation was the only factor that predicted a limited OS (hazard ratio = 10.00) and EFS (hazard ratio = 16.39) rates. Intensive chemotherapy followed by HSCT could be an effective strategy for treating children with rr-NHL and may offer improved survival for a significant group of pediatric patients, particularly those with chemosensitive disease at transplantation.

RESUMEN

Atas E, Koç O, Artik HA. Clinical features and treatment results in children with hemangioma. Turk J Pediatr 2017; 59: 254-260. Hemangioma is a frequent disease which has a proliferative and involution phase. In this single center retrospective study, we evaluated clinical and therapeutic features of hemangiomas in children (n: 49). The median (range) age at onset and at admission were 21 days (10 days-156 months) and 7 months (0.25-192 months), respectively. The localization of lesions was: head region (n: 28; 57.2%), trunk (n: 8; 16.3%) trunk, limb (n: 8; 16.3%), and neck region (n: 5; 10.2%) neck region. Seventeen patients (34.7%) were treated. Following treatments were used: propranolol alone in 12 (24.5%) patients, steroid alone in 2 (4.1%) patients, prednisone plus propranolol in 2 (4.1%) patients, and propranolol plus surgery in 1 (2.0%) patient. The number of hemangioma (n > 1) (p = 0.026, OR = 9.5, 95% CI 1.3-69.2) and treatment other than observation (p = 0.008, OR = 10.5, 95% CI 1.8-59.1) were significant predictors in the univariate analysis; treatment other than observation was an independent predictor for clinical response (p = 0.014, OR = 9.8, 95% CI 1.5-90.9).

RESUMEN

AIM OF STUDY: Neutropenic fever is a source of morbidity and mortality in children with cancer. It is not possible to detect the causative agent in cultures in most cases; the research for a marker that can show the severity of the disease is ongoing. We evaluated the role of adrenomedullin (ADM) at predicting prognosis on patients with febrile neutropenia, which has been proven to be a good prognostic marker for diseases with high morbidity and mortality, such as heart failure, ischemic ventricular dysfunction, sepsis, and systemic inflammatory response syndrome. MATERIALS AND METHODS: We recorded the 36 febrile episodes of 14 children receiving chemotherapy due to solid tumors. There were 10 events with unknown origin in the low-risk group, while in the high-risk group, there were 17 events with unknown origin, 8 events with microbiological origin and 1 event with clinically proven infection. Cultures were positive only in the high-risk group. However, the changes of ADM levels through time periods (first, second, third, and seventh days) were not significant. RESULTS: The first-day plasma ADM levels significantly predicted the presence of culture positivity (AUC 0.628, 95% CI 0.40-0.85, p = 0.303) and high-risk patients with neutropenic fever (AUC 0.76, 95% CI 0.56-0.97, p = 0.016). CONCLUSION: Our study showed that increased plasma ADM was correlated with high-risk neutropenic fever and culture positivity. The ADM levels in the high-risk group were clearly high at the diagnosis and continued to the end of the treatment.

RESUMEN

OBJECTIVE: The prognostic factors and a new childhood prognostic index after autologous hematopoietic stem cell transplantation (AHSCT) in patients with relapsed/refractory Hodgkin's lymphoma (HL) were evaluated. MATERIALS AND METHODS: The prognostic factors of 61 patients who underwent AHSCT between January 1990 and December 2014 were evaluated. In addition, the Age-Adjusted International Prognostic Index and the Childhood International Prognostic Index (CIPI) were evaluated for their impact on prognosis. RESULTS: The median age of the 61 patients was 14.8 years (minimum-maximum: 5-20 years) at the time of AHSCT. There were single relapses in 28 patients, ≥2 relapses in eight patients, and refractory disease in 25 patients. The chemosensitivity/chemorefractory ratio was 36/25. No pretransplant radiotherapy, no remission at the time of transplantation, posttransplant white blood cell count over 10x103/µL, posttransplant positron emission tomography positivity at day 100, and serum albumin of <2.5 g/dL at diagnosis were correlated with progression-free survival. No remission at the time of transplantation, bone marrow positivity at diagnosis, and relapse after AHSCT were significant parameters for overall survival. CONCLUSION: The major factors affecting the progression-free and overall survival were clearly demonstrated. A CIPI that uses a lactate dehydrogenase level of 500 IU/L worked well for estimating the prognosis. We recommend AHSCT at first complete remission for relapsed cases, and it should also be taken into consideration for patients with high prognostic scores at diagnosis.

RESUMEN

Clofarabine is an effective drug in relapsed leukemia and lymphoma that has some adverse effects which can be fatal like capillary leak syndrome (CLS). Identification and management of CLS is important that may result in mortality. Although prophylactic treatment with steroids may prevent CLS and improve survival, intravenous immunoglobulins are used in the treatment with great success in steroid resistant cases. However, the knowledge about the effects and the dose of intravenous immunoglobulins (IVIG) in pediatric patients is limited. Herein, we reported a patient with relapsed lymphoma who developed CLS successfully and was treated with IVIG.

RESUMEN

There are a lot of early or late side effects of chemotherapies. One of them is Raynaud's phenomenon (RP). Vascular toxicity associated with antineoplastic agents is notified in bleomycin alone therapy or in combination with cisplatin, vinblastine, and vincristine. The mechanism of RP associated with antineoplastic agents is unknown. All children receiving vinblastine, vincristine, bleomycin and cisplatin therapy, are followed and questioned about their complaint on RP. Long-term follow-up of surviving patients is recommended. Oncologists should be aware of the potential late toxic effects of antineoplastic drugs.

RESUMEN

After hematopoietic stem cell transplantation (HSCT), patients may suffer from bleeding. One of the bleeding type is gastrointestinal (GI) which has serious morbidity and mortality in children with limited treatment options. Herein, we presented a child with upper GI bleeding post autologous HSCT controlled successfully by using recombinant activated factor VII (rFVIIa) and octreotide infusion.

RESUMEN

Chemotherapy regimens, including doxorubicin used in primitive neuroectodermal tumor's (PNET) treatment can cause life-threatening disorders in cardiac functions. Follow-up of cardiac functions in the clinical course is very important during treatment with ejection fraction (EF) and shortening fraction (SF). However, sometimes the detection of cardiac failure with EF and SF cannot be possible. In this condition, we may need new evaluation test. Herein, we wanted to present a child with PNET of the chest wall suffered from antracycline toxicity and indicate that close monitoring of cardiac function could be important.

RESUMEN

This study evaluates the outcome of 66 pediatric patients with rrHL who underwent autoHSCT. Twenty-nine patients experienced early relapse, and 19 patients experienced late relapse. Of 18 newly diagnosed with HL, 13 were primary refractory disease and five had late responsive disease. At the time of transplantation, only 68% of the patients were chemosensitive. The majority of patients received BCNU + etoposide + ara-C + melphalan for conditioning (45/66), and peripheral blood (56/66) was used as a source of stem cells. After a median follow-up period of 39 months, 46 patients were alive. At five yr, the probabilities of OS, EFS, the relapse rate, and the non-relapse mortality rate were 63.1%, 54.3%, 36.4%, and 9.1%, respectively. The probability of EFS in chemosensitive and chemoresistant patients at five yr was 72.3% and 19%, respectively (p < 0.001). Multivariate analysis showed that chemoresistant disease at the time of transplantation was the only factor predicting limited both OS (hazard ratio = 4.073) and EFS (hazard ratio = 4.599). AutoHSCT plays an important role for the treatment of rrHL in children and adolescents, and survival rates are better for patients with chemosensitive disease at the time of transplantation.
