Unusual Ampullary Presentation of Pediatric Burkitt Lymphoma: Case Report and Literature Review.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Burkitt lymphoma (BL) is a highly aggressive B-cell non-Hodgkin lymphoma that typically presents with abdominal masses; ampullary involvement with obstructive jaundice and gastrointestinal bleeding is exceptionally rare in children. Early biliary decompression can be crucial to permit timely chemotherapy. Case presentation: A 14-year-old boy presented with 1 week of worsening abdominal pain, non-bilious vomiting, constipation, jaundice, and melena. Examination showed pallor, icterus, firm hepatomegaly, and a palpable epigastric mass. Laboratory testing revealed cholestatic liver function abnormalities and elevated pancreatic enzymes. Ultrasound and contrast computed tomography demonstrated a large retroperitoneal mass compressing the biliary tree. Upper gastrointestinal endoscopy identified a friable, ulcerated ampullary mass with active bleeding. Biopsy confirmed BL by morphology (starry-sky) and immunohistochemistry/fluorescence in situ hybridization (CD20+, CD10+, c-MYC+, Ki-67 ~95%). Main diagnosis made was pediatric BL presenting with ampullary involvement causing obstructive jaundice and upper gastrointestinal bleeding. Given persistent cholestasis and bleeding risk, the patient underwent Roux-en-Y choledochojejunostomy for biliary decompression, followed by initiation of rituximab-cyclophosphamide-vincristine-doxorubicin-high-dose methotrexate/rituximab-ifosfamide-etoposide-high-dose cytarabine (R-CODOX-M/R-IVAC) with central nervous system prophylaxis. Post-operative bilirubin improved, and early chemotherapy cycles were tolerated. During the 2-week hospitalization, the patient had symptomatic improvement; however, objective radiologic response could not be documented because care was transferred and post-transfer positron emission tomography-computed tomography was unavailable. Conclusion: Ampullary BL should be considered in pediatric patients with obstructive jaundice and upper gastrointestinal bleeding. Surgical biliary decompression can stabilize cholestasis and facilitate timely multi-agent chemotherapy.
