Characteristics and Survival Outcomes of Children With Hodgkin Lymphoma Treated Primarily With Chemotherapy.

BACKGROUND: Hodgkin disease is a malignant tumor of the lymphatic system that comprises ∼6% of childhood cancers. In developing countries, efforts are made to ensure adherence to standard protocol/regimens, study patients' outcomes, and compare with that in developed world. MATERIALS AND METHODS: We conducted a retrospective medical records' review of 212 children younger than 20 years presenting to The Indus Hospital in Pakistan with previously untreated Hodgkin lymphoma between August 2000 and December 2012. We collected demographic and other epidemiologic variables such as age, sex, stage, subtype of disease, and survival outcomes. RESULTS: The mean±SD age of patients at time of diagnosis was 9.0±3.8 years with a male to female ratio of ∼4.7:1. In total, 44 (20.8%) patients were 5 years of age or above at presentation. Overall, 131 (61.8%) patients presented with B-symptoms and mixed cellularity was the most frequently diagnosed subtype in 65.1% of cases. In total, 170 (80.2%) achieved full remission after completion of chemotherapy. Patients were treated with alternating cycles of ABVD (Adriamycin, Bleomycin, Vincristine, and Dacarbazine) and COPDAC (Cyclophosphamide, Vincristine, Prednisolone, and Dacarbazine). The majority (n=114, 59.1%) received 6 cycles of chemotherapy, 44 (22.8%) received ≤4 cycles followed by 24 (12.4%) receiving 8 cycles. Radiotherapy was administered only to those patients with significant residual disease at the end of chemotherapy (n=20, 10%). The 5-year overall survival and event-free survival in our cohort was 89.6% and 82.1%, respectively. CONCLUSION: Our findings suggest that treatment with 4 to 8 alternating cycles of ABVD/COPDAC has an excellent outcome in childhood Hodgkin disease.

Clinical impact and cost-effectiveness of noncontrast MRI in the evaluation of suspected appendiceal abscesses in children.

BACKGROUND: Noncontrast MRI has been shown to be feasible in children with postappendectomy abscesses and helps guide clinical management, but its role in preoperative appendiceal abscesses is unclear. PURPOSE: To determine the cost-effectiveness and impact on clinical management of noncontrast MRI in pediatric patients with suspected appendiceal abscess, both pre- and postappendectomy. STUDY TYPE: Retrospective cohort study. POPULATION: In all, 82 children under the age of 18 years with suspected appendiceal abscess on ultrasound. FIELD STRENGTH/SEQUENCE: Diffusion-weighted imaging and T2 -weighted single-shot fast spin-echo imaging of the abdomen and pelvis at 1.5T and 3T. ASSESSMENT: The presence, location, size, and apparent diffusion coefficient (ADC) of fluid collections and the presence of a drainage path was noted by three pediatric radiologists. Imaging time, completeness of the exam, and impact on clinical management was recorded. The incremental cost-effectiveness ratio was calculated for MRI relative to CT, taking into account hospital charges, radiation exposure, and risk of adverse reaction to iodinated contrast. STATISTICAL TESTS: Descriptive statistics were used. Intraclass correlation coefficient and Fleiss' kappa were used to assess interobserver variation. Proportions were compared using Fisher's exact test (statistical significance at P < 0.05). RESULTS: MRI confirmed the presence of collections in most cases, with alternative diagnosis established in 10 patients (Tubo-ovarian abscess n = 7, Crohn's disease, ileal anastomotic leak, and Birkitts lymphoma each n = 1). MRI showed the presence of a safe drainage pathway in 92-97% of pelvic abscesses and 86-98% of abdominal abscesses compared with 7-10% and 75-81%, respectively, for ultrasound. MR was cost-effective compared with CT, taking into account the direct charges, risk of radiation induced cancer, and adverse reaction to iodinated contrast. DATA CONCLUSION: Noncontrast MR is cost-effective and affects clinical management in a significant proportion of children with suspected appendiceal abscesses. LEVEL OF EVIDENCE: 5 Technical Efficacy: Stage 6 J. Magn. Reson. Imaging 2019.

"Bottle Brush Sign"-Spinal Meningeal Disease on 18F-FDG PET-CT Scan.

A 30-year-old man with a history of stage IV AE diffuse large cell lymphoma of left proximal humerus presented with new onset lower limb weakness at completion of chemotherapy. The F-FDG PET-CT scan showed increased intraspinal uptake from T12 to S1 vertebrae with unique "bottle brush" appearance in keeping with spinal meningeal disease. The leptomeningeal disease was further confirmed on correlative MRI scan.

Squamous cell carcinoma of tongue in an 11-year-old girl.

We report the case of an 11-year-old girl with squamous cell carcinoma of the tongue. This is a very rare disease in children with only a few cases reported in the literature. There is a great need to create awareness of the harmful and potentially lethal effects of chewing paan and betel nut not only in adults but also in children. Pediatricians and family physicians should also be aware of the possibility of this disease entity occurring at an earlier age so as to decrease delay in diagnosis and initiation of treatment.
