RESUMO

Our patient had an extremely rare type of pediatric Diffuse Midline Glioma (DMG) with modified H3 K27 that occurred in the cervical spinal cord. Due to its location in the spinal cord, slow clinical presentation with torticollis for 7 months, and the non-specific radiological appearance of this tumour, it was initially considered to be a low-grade glioma. Based on imaging findings, the neurosurgery team performed a complete surgical resection, but the pathological features were consistent with a high-grade, diffuse midline glioma. Therefore, we are reporting a case of an altered high-grade DMG H3K27 glioma, which is difficult to diagnose due to its slow clinical symptoms which caused a delay in diagnosis, non-specific imaging, and with difficulty in accessing histopathological markers in low and middle income countries (LMIC).

RESUMO

BACKGROUND: In 2018, the World Health Organization (WHO) launched the Global Initiative for Childhood Cancer (GICC). The goal is to achieve a global survival rate of at least 60% for all children with cancer by 2030. Morocco was designated as a pilot country for this initiative. PROCEDURE: This retrospective study included a cohort of children aged 0-15 years, with one of the six indexed cancers (acute lymphoblastic leukemia [ALL], Burkitt lymphoma [BL], Hodgkin lymphoma, retinoblastoma [RB], Wilms tumor or nephroblastoma, low-grade glioma), diagnosed between January 1, 2017 and December 31, 2019 at the six Moroccan Pediatric Hematology and Oncology units. Patients were followed-up until August 31, 2020. The Kaplan-Meier method was used to estimate survival rates, the log-rank test for comparing survival curves, and the Cox model for identifying prognostic factors. RESULTS: Data on 878 patients were included in the study. The most frequently reported cancer type was ALL (n = 383, 43.6%), followed by Wilms tumor (n = 139, 15.8%) and BL (n = 133, 15%). Most patients were less than 5 years of age (n = 446, 50.9%) and the male/female ratio was 1.46. The 1, 2, and 3-year overall survival rates were 80.1%, 73.6%, and 68.2%, respectively. In a multivariable Cox regression model, care center, cancer type, age group, and distance to the care center were statistically significantly associated to survival. Patients aged 10 years and older and patients living more than 100 km from the care center were more likely to die (respectively, HR = 1.39, p = .045 and HR = 1.44, p = .010). CONCLUSION: The reported results represent the baseline for measuring the impact of GICC implementation in Morocco.

RESUMO

Teratomas are neoplasms of the embryonic tissues that typically arise in the gonadal and sacrococcygeal regions. Primary adrenal teratoma are extremely rare and only few cases were published in literature. Teratomas contain more than one embryonic germ cell layer, mostly elements derived from ectoderm and least frequently from endoderm. Though these tumors are mostly benign, malignant transformation may occur. Treatment includes surgical removal. We report a rare case of a primary mature retroperitoneal teratoma in an infant with liver metastasis. Imaging modality CT and MRI were useful in diagnosis. The diagnostic and therapeutic challenges of dealing with such a case have been discussed and the literature reviewed.

RESUMO

The myelotoxicity of most chemotherapeutic regimens used to treat children and adolescents with cancer require the use of daily subcutaneous administration of hematological growth factors (mainly granulocyte colony-stimulating factor). Recently, pegfilgrastim (Neulasta), a product with a long half-life, resulting in once-per-cycle dosage, was introduced to prevent neutropenia in adults, and provided safety and efficacy similar to that provided by daily injection of filgrastim. To evaluate retrospectively the use of pegfilgrastim in children with cancer, we conducted a single-center retrospective study evaluating the use of pegfilgrastim in patients over 40 kg, who received chemotherapy for cancer from September 2003 to December 2005. A single subcutaneous injection of pegfilgrastim 100 microg/kg (maximum dose 6 mg) per chemotherapy cycle in children receiving myelosuppressive chemotherapy was given. One hundred and twenty-six administrations of pegfilgrastim were analyzed in 28 pediatric patients treated for cancer (11 girls, 17 boys) with a median age of 14.5 years (range 12-18 years) and median weight of 50.5 kg (range 40-82 kg). Patients received a median dose of pegfilgrastim of 100 microg/kg (range 73-117). The median total number of injections per patient was 4 (range 1-14). The incidence of grade 4 neutropenia by cycle was 48%, the mean duration of neutropenia was 3 days (range 1-13 days). The median values of absolute neutrophil count nadir was 0.425 x 10(9)/l (range 0-9.9 x 10(9)). Febrile neutropenia occurred in 18 of the 126 patients on pegfilgrastim use (14%) with full recovery in all patients. The median total duration of intravenous antibiotic therapy was 5 days (range 2-14 days). Bone pain (four) and headaches (two) were the most frequent adverse events reported. No correlation was found between the administered dose of Neulasta and hematological data. In conclusion, the use of pegfilgrastim was safe and well tolerated in children with cancer treated with myelosuppressive chemotherapy. Safety and efficacy of pegfilgrastim must be compared with filgrastim and evaluated in younger children with lower body weight.
