Diagnostic challenges and therapeutic approaches in pediatric osteosarcoma: A case report.
Article in International journal of surgery case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 and importanceOsteosarcoma (OS) is the most common primary malignant bone tumor. Radiological features may resemble benign processes, making diagnosis challenging. Delayed recognition can affect treatment outcomes, as timely intervention is crucial for managing the tumor effectively. CASE PRESENTATION: This report discusses the case of a 9-year-old girl who presented with left knee pain, without signs of fever or inflammation. Radiological imaging revealed a large, multilocular osteolytic lesion in the distal femur with sclerotic margins and no periosteal reaction, initially suggesting subacute osteomyelitis. A biopsy confirmed the diagnosis of OS. Staging studies revealed no distant metastases. The patient underwent neoadjuvant chemotherapy followed by a two-stage surgical procedure using the induced membrane technique for bone reconstruction. Histological examination of the resected tumor showed a high-grade osteoblastic OS with a good response to chemotherapy. After adjuvant chemotherapy, the patient achieved complete remission. One year postoperatively, a non-vascularized autograft was performed using fibula and iliac grafts. DISCUSSION: The induced membrane technique proved successful, with good functional results and no complications. This case highlights the diagnostic challenges of osteosarcoma, particularly when the radiological features resemble benign conditions. Early diagnosis and a multidisciplinary approach, including surgery and chemotherapy, are essential for improving patient outcomes. Follow-up is critical to detect late complications in OS survivors.
conclusionPediatric osteosarcoma presents significant diagnostic and therapeutic challenges. Early detection and a combination of surgery and chemotherapy are key to improving outcomes.
