[A Case of Resection of Brain Metastasis from Pancreatic Tail Cancer with Multiple Lung and Liver Metastases]

The patient is a 66-year-old man. He came to the hospital for chest and back pain, and a CT scan of the chest and abdomen showed the pancreatic tail cancer and multiple lung and liver metastases. Systemic chemotherapy was performed, but during the course of the treatment, he had difficulty in speaking, and a head MRI scan was performed, which led to suspicion of brain metastasis of pancreatic cancer. At this point, the primary tumor and lung liver metastases were well controlled by chemotherapy, so brain tumor resection was performed. Postoperatively, the patient had slight residual aphasia, tinnitus, and mild hearing loss, but the patient did not develop any other symptoms. After that, multiple bone metastases were discovered, and from then on, the patient received mainly palliative care, and died from the underlying disease 57 months after the initial diagnosis and 20 months after brain tumor surgery. No intracerebral recurrence was observed during the course of treatment. Pancreatic cancer with brain metastasis is rare, no treatment has been established, and its prognosis is extremely poor. Surgical resection of metastatic brain tumors in pancreatic cancer may improve the prognosis when the primary tumor and other metastases are well controlled.
