Abstract
Background: Granulocyte colony-stimulating factor (G-CSF)-producing tumors have been reported in various organs, and the prognosis of patients with G-CSF-producing pancreatic cancers is particularly dismal. In this report, we present a case of G-CSF-producing anaplastic carcinoma of the pancreas (ACP), characterized by early postoperative recurrence and rapid, uncontrolled growth.
Case presentation: A 74-year-old man presented to our hospital with complaints of abdominal fullness and pain after eating. On admission, it was observed that the peripheral leukocyte counts and serum G-CSF levels were significantly elevated (23,770/µL and 251 pg/mL, respectively). Computed tomography of the abdomen revealed a pancreatic head tumor involving the superior mesenteric vein. Pathologically, ultrasound-guided fine-needle aspiration confirmed ACP. Subsequently, we performed a subtotal stomach-preserving pancreaticoduodenectomy with portal vein reconstruction and partial transverse colon resection. On postoperative day (POD) 7, the leukocyte count decreased from 21,180/μL to 8490/μL; moreover, computed tomography revealed liver metastasis. Therefore, mFOLFILINOX chemotherapy was initiated on POD 30. However, the tumor exhibited rapid progression, and the patient died on POD 45.
Conclusions: G-CSF-producing ACP is rare, and the prognosis of patients is extremely poor. Basic research is required to develop effective drugs against G-CSF-producing tumors, and large-scale studies using national databases are needed to develop multidisciplinary treatment methods.
