Thyroid abnormalities in patients with Hodgkin lymphoma: The importance of close surveillance.

INTRODUCTION: Survival in paediatric patients with Hodgkin lymphoma (HL) has increased over the last decades. However, these patients are at increased risk of developing late thyroid sequelae due to the treatment with irradiation and alkylating agents. METHODS: We conducted an observational and retrospective study in patients with a diagnosis of HL between 2007 and 2022, in a hospital that is a paediatric oncology reference centre, through the review of electronic health records. We collected data on demographic (age, sex), clinical, radiological and histopathological variables, the dosage of alkylating agents and radiotherapy (RT) and on thyroid disorders using Microsoft Excel. The data analysis was conducted with SPSS version 17, using the Fisher exact test for qualitative data, a nonparametric test for quantitative data and Kaplan-Meier curves. RESULTS: Sixty patients received a diagnosis of HL from 2007 to 2022. The median duration of follow-up was 78.5 months. There were 4 detected cases of hypothyroidism, 5 of thyroid nodules and 1 of subclinical hyperthyroidism. Treatment with RT was significantly associated with the development of hypothyroidism (P= .026), thyroid nodules (P= .01) and thyroid disease overall (P= .003). We estimated that the risk of thyroid disease increased 8-fold with each additional Grey received (hazard ratio, 1.081; 95% CI, 1.014-1.152; P= .017). CONCLUSION: Hodgkin lymphoma patients treated with RT are at increased risk of late thyroid disorders, mainly hypothyroidism and malignancy. This risk is greater the higher the RT dosage and the longer the follow-up. We did not find evidence of an association between the use of alkylating agents and an increase in the risk of thyroid disease.

Atención al adolescente con cáncer. ¿Qué ha cambiado en nuestro país en una década? / Adolescent cancer care: What has changed in Spain in the past decade?

Introducción y objetivo: En el año 2012 el Grupo de trabajo de adolescentes con cáncer publicó los resultados de una encuesta sobre la asistencia a adolescentes en España como punto de partida para futuras actuaciones. Nuestro objetivo fue evaluar si las líneas de trabajo han supuesto cambios asistenciales en la última década. Material y métodos: Encuesta que consta de las mismas preguntas analizadas y publicadas en el año 2012. La encuesta se divide en: epidemiología, atención psicosocial, infraestructuras, tratamiento y seguimiento de los adolescentes con cáncer. Se envió a todos los hospitales con unidades de hematología y oncología pediátrica. Se realizó un análisis estadístico descriptivo de los resultados. Resultados: El porcentaje de pacientes hasta los 18 años tratados en unidades pediátricas ha aumentado del 35,9% al 77,5%. Las hemopatías malignas tratadas en unidades pediátricas se incrementan del 31% al 52% y los tumores sólidos del 49% al 85%. En 2012 30 (39) unidades referían que los casos nuevos de adolescentes representaban un 10%. Actualmente 14 (40) mantienen este porcentaje. Hace una década no existían unidades específicas para adolescentes con cáncer en España. Actualmente, 7 (40) centros disponen de unidades. La atención psicológica para adolescentes apenas ha variado. El seguimiento de supervivientes se realiza por especialistas pediátricos en el 82,5% de los centros. Conclusiones: El trabajo para centralizar los cuidados de adolescentes con cáncer en unidades específicas multidisciplinarias, o en su defecto pediátricas, se ve reflejado en los cambios en la atención sanitaria en nuestro país en la última década. Aún queda un largo recorrido en pilares fundamentales en el abordaje de esta población. (AU)

Introduction and objective: In 2012, the Adolescents with Cancer working group published the results of a survey on care delivery for the adolescent population in Spain as a starting point for future intervention. The aim of this nationwide survey was to outline the current situation and assess whether the implemented strategies have resulted in changes in care delivery. Material and methods: Survey consisting of the same items analysed and published in 2012. The questionnaire was structured into sections devoted to epidemiology, psychosocial care, infrastructure, treatment and follow-up of adolescents with cancer. It was submitted to all hospitals in Spain with a paediatric haematology and oncology unit. We conducted a descriptive analysis of the results. Results: The percentage of patients aged up to 18 years managed in paediatric units has increased from 35.9% to 77.5% in the past decade. The proportion of malignant blood tumours treated in paediatric units increased from 31% to 52%, and the proportion of solid tumours from 49% to 85%. In 2012, 30 units (out of 39) reported that new cases in adolescents amounted to up to 10% of the total. At present, only 14 (out of 40) continue to report this percentage. A decade ago, there were no specific adolescent cancer units in Spain. Now, 7 centres (out of 40) have specific multidisciplinary units. There has been little change in psychological support services for adolescents. The follow-up of survivors is carried out by paediatric specialists in 82.5% of the hospitals. Conclusions: The efforts made to centralise the care of adolescents with cancer in specific multidisciplinary adolescent units or, failing that, paediatric units, is reflected in the changes in care delivery in Spain in the past decade. Much remains to be done in key components of the management of adolescents with cancer. (AU)

Composite sarcoma of bone with focal rhabdomyosarcoma and lymph node metastasis in an adolescent.

Composite sarcoma of bone is a very rare entity that primarily affects adolescent and young adult patients. It usually combines areas of liposarcoma and osteosarcoma, and up to 60% of cases have metastatic disease at diagnosis. It is a highly aggressive pathology with intrinsic resistance to bone sarcoma conventional treatments. The prognosis is poor, with long-term survival rates not exceeding 30%. We present the case of an adolescent female diagnosed with an aggressive composite sarcoma of bone with rhabdomyosarcoma foci and loco-regional lymph node involvement.

Secondary Intracranial Hypertension in Pediatric Patients With Leukemia.

BACKGROUND: We investigated the clinical characteristics of a pediatric population with hemato-oncological disease and intracranial hypertension, analyze the therapeutic response and outcome, and compare its characteristics with respect to a control group with idiopathic intracranial hypertension. METHODS: We retrospectively analyzed patients with hemato-oncological disease and secondary intracranial hypertension in our center during the past five years. We compared these individuals with a historical cohort with idiopathic intracranial hypertension from our institution (control group). RESULTS: We identified eight patients, all with leukemia, and 21 controls. Mean age at diagnosis was 10.6 years, and 62% of individuals were female. Most of them were under treatment with drugs (62% corticosteroids, 75% active chemotherapy). Mean opening pressure of cerebrospinal fluid was 35 cm H2O. All had headache, but only 28% complained of visual symptoms. Only 12.5% exhibited papilledema at the time of diagnosis (versus 71% in controls). All of them were treated with acetazolamide, with average therapy duration of nine months, and all had a favorable outcome (versus 57% of controls who needed second-line treatment). None of them showed long-term visual complications (versus 20% of controls). CONCLUSIONS: Patients with hemato-oncological disease and secondary intracranial hypertension may not develop typical symptomatology. Thus, diagnosis and recognition of this entity among this cohort may be difficult. Associated factors are diverse and do not show an obvious causal relationship. A high index of suspicion must be maintained for diagnosis, because a favorable outcome is expected with prompt treatment. Acetazolamide is effective as a first-line therapy and caused few side effects.
