Introduction: Retinoblastoma (RB) is a prototype of heritable cancers. It is more common in the lower socioeconomic strata. Delayed presentation significantly reduces the overall outcome. We have analyzed the epidemiological and clinical data of children who were diagnosed with RB between the years 2009 and 2014. Aim: RB being a disease of the poor, delayed presentation is common due to lack of awareness. We have analyzed the epidemiological profile of our patients and tried to establish the link between delayed presentation and the presence of high-risk features. High-risk features are associated with higher chance of metastasis and poor rates of vision salvage in RB. Methodology: Data were collected in a retrospective manner from the patient case files retrieved from the Medical Records Department, Kidwai cancer Institute. The data were analyzed using Excel and SPSS software (IBM Corp. released 2016, IBM SPSS statistics software for Mac OS, version 24, IBM Corp., Armonk, NY). Results: A total of 53 patients were diagnosed with RB in the years 2009–2014. There was a male predominance with 1.2:1 incidence. Bilateral RB was present in 21 cases. The mean age of children with bilateral RB was 2.1 years, against 1.5 years in unilateral cases. High-risk features such as optic nerve invasion, choroidal invasion, intracranial extension, and orbital involvement were found in 12, 6, 5, and 5 eyes, respectively. Bone marrow involvement was detected in 5% and lung metastasis in 2%. Intracranial involvement was found in 10.4% and cerebrospinal fluid positivity in 15%. Children with high-risk features had a significant delay in presentation in comparison to those without high-risk features ( P = 0.035). Conclusion: Incidence of metastatic disease and delayed presentation is still high in developing countries. Routine eye examination during vaccination visits can ensure early diagnosis and appropriate referral in many of these children.

Introduction The Capizzi-style methotrexate (MTX) is an integral part of acute lymphoblastic leukemia (ALL) treatment. The escalating dose of MTX originally used in the United Kingdom and Children’s Oncology Group protocols along with L-asparaginase has been modified in the Indian Childhood Collaborative Leukemia (ICiCLe) group protocol where L-asparaginase has been omitted. The data regarding the incidence of toxicities and ease of administration on the Capizzi-style interim maintenance is not robust. Objectives We have compiled our experience with administration and toxicity profile in children with intermediate-risk ALL. Materials and Methods A retrospective data collection of all children diagnosed with intermediate-risk ALL as per the ICiCLe risk stratification in the year 2019 was included in the analysis. Each cycle of MTX was started after ensuring an absolute neutrophil count of >750/mm3 and transaminases <2 upper limit of normal. As a unit protocol, pre- and post-MTX hydration was administered in all our children. No urine pH or midcycle biochemical parameter monitoring was done. Statistical analysis was done using Microsoft Excel and SPSS version 24 IBM Corp. in Armonk, New York, United States. Results Forty-six children were included in the study. The median age of children in our study was 6 years (range: 1 year 2 months–12 years). Undernutrition was associated with a significant increase in toxicity (p = 0.02). Fifty-two percent of children had evidence of toxicity, elevated transaminases being the most common. There were recurring symptoms resulting in 53 episodes of toxicities overall. Incidence of toxicity was more in the early cycles (<3). Conclusion The pre- and post-MTX hydration is an effective way to reduce toxicities with the Capizzi-style MTX and this course can be administered with ease on outpatient basis with minimal need for monitoring or admission.

Wilms tumor is the second most common intraabdominal malignancy in childhood. Vessel invasion with thrombus formation is a well-known phenomenon in Wilms tumor and is found in 30% of these children. This report describes a 4-year-old boy with a left kidney Wilms tumor and extensive thrombi formation with intracardiac extension. He underwent a left radical nephrectomy under cardiopulmonary bypass following a single dose of chemotherapy. Emergency surgery with cardiopulmonary bypass may be lifesaving in children with cardiac compromise in the presence of extensive thrombosis.
