Abstract
PURPOSE: The aim of this study is to analyze the clinical and pathological features of pancreatoblastoma (PB) and to obtain better management for patients with relapsed or metastatic disease. METHODS: Four cases treated in our institution and 59 cases reported previously in the literature from the PubMed biomedical database (2000-2020) were reviewed and analyzed. RESULTS: Four cases with PB presented with abdominal pain and palpable abdominal masses, with the tumor size ranging from 5.2 to 18 cm in diameter. The invasion of the splenic vein and superior mesenteric artery, duodenum, and lymph nodes were risk factors for PB. Three cases were treated with combination therapy and showed favorable outcomes, while one case was treated with chemotherapy alone due to tumor progression and died of the disease. Squamous corpuscles were revealed in the tumor samples and considered a defining component for histological diagnosis. CONCLUSIONS: Multidisciplinary diagnosis plays an important role in clinical management. The risk factors should be considered in the therapeutic stratification of PB before surgery.
