BACKGROUND: A number of patients with lung cancer have distant metastases at the time of diagnosis. The most common sites for metastases are liver, brain, etc. However pancreatic metastasis is relatively rare, with an insidious onset and poor prognosis. There are no sufficient recognition and attention of lung cancer with pancreatic metastasis. The aim of this study was to summarize the pathological characteristics, clinical manifestations, therapies and prognosis of pancreatic metastases of lung cancer, thus further exploring better managements for the best prolonged survival or quality of life. METHODS: 42 patients of lung carcinoma with confirmed pancreatic metastases hospitalized at the Peking Union Medical College Hospital from January 1998 to December 2018 were identified. We reviewed all medical documentations for complete information including diagnosis, treatment, prognosis features. RESULTS: 24 (57%) patients were asymptomatic or presented with non-specific symptoms. 18 (43%) patients had symptoms related to pancreatic metastases, such as acute pancreatitis, obstructive jaundice or pain of lumber back. The median overall survival (OS) was 8.8 months. Multivariate analysis suggested patients with symptoms had a poor prognosis compared with patients without pancreatic symptoms [(hazard ratio, HR)=2.645, 95%CI: 1.013-6.910, P=0.047]. Patients received chemotherapy had better prognosis versus those who did not [HR=0.158, 95%CI: 0.049-0.512, P=0.002]. CONCLUSIONS Pancreatic metastasis of lung cancer is rare and the prognosis is poor. Chemotherapy can prolong survival significantly. Local radiotherapy of the pancreas may alleviate local symptoms, improve quality of life, facilitate further systemic chemotherapy for patients to prolong survival. Patients with symptoms related to pancreatic metastases can benefit from the comprehensive treatment of chemotherapy combined with local pancreatic radiotherapy.

Leiomyosarcoma is an uncommon tumor that originates from various organs, including uterus, kidney, retroperitoneum, and soft tissues. In particular, leiomyosarcoma of the stomach is extremely rare. Only 9 cases have been reported worldwide since the discovery of KIT-activating mutation. A 48-year-old woman was admitted to our hospital with abdominal discomfort and generalized weakness. Upon detection of multiple nodules in both lung on chest posterior-anterior radiograph taken at the time of admission, chest CT was performed and it revealed multiple mass lesions in the lung, liver, and pancreas along with multiple lymph node metastases. On endoscopic examination, a 2.0 cm sized ulcerofungating mass lesion was found on the stomach body. Biopsy was performed and the mass lesion proved to be leiomyosarcoma confirmed by immunohistochemical staining. Chemotherapy was thus initiated, but the patient died after one year due to tumor progression. Our experience suggests that leiomyosarcoma can manifest aggressive behavior in its early stage. Herein, we report a case of gastric leiomyosarcoma with multiple metastases along with review of relevant literature.

A 31-yr-old man with abdominal pain was diagnosed with a pancreatic endocrine tumor and multiple hepatic metastases. Despite optimal treatment with interferon alpha, a somatostatin analog, local therapy with high-intensity focused ultrasound ablation for multiple hepatic metastases, and multiple lines of chemotherapy with etoposide/cisplatin combination chemotherapy and gemcitabine monotherapy, the tumor progressed. As few chemotherapeutic options were available for him, sorafenib (800 mg/day, daily) was administered as a salvage regimen. Sorafenib was continued despite two episodes of grade 3 skin toxicity; it delayed tumor progression compared to the previous immunotherapy and chemotherapy. Serial computed tomography scans showed that the primary and metastatic tumors were stable. Thirteen months after beginning targeted therapy, and up to the time of this report, the patient is well without disease progression. We suggest that sorafenib is effective against pancreatic endocrine tumors.

Peutz-Jeghers syndrome (PJS), which is characterized by multiple hamartomatous polyps of the gastrointestinal tract and mucocutaneous pigmentation, is a rare autosomal dominant disease. This syndrome is often represented as a surgical emergency with complications of the polyps such as intussusception, small bowel obstruction, bleeding, and volvulus. In particular, many studies have reported that patients with this syndrome have a high risk of gastrointestinal or extragastrointestinal malignancy including gastric, duodenal, jejunal, ileal, and colonic carcinoma as well as malignancies involving other organs such as the gallbladder, biliary tract, pancreas, tonsils, breast, and reproductive system. However, there are few reported cases of an association of this syndrome with extraintestinal malignancy. In addition to that, there is no reported case of this syndrome with malignant tumor or intraductal papillary mucinous tumor of pancreas in Korea. We experienced a case of PJS accompanying intraductal papillary mucinous carcinoma of the pancreas, therefore we report this case with literatures reviewed.

Primary hepatic epithelioid hemangioendothelioma is a rare neoplasm of endothelial origin. The clinical manifestations are nonspecific, ranging from complete absence of symptoms to hepatic failure and death. Spontaneous rupture of a hepatic epithelioid hemangioendothelioma is an extremely rare presentation. We present a case of primary hepatic epithelioid hemangioendothelioma in a 65-year-old male patient with alcoholic liver cirrhosis. He was hospitalized due to epigastric pain and multiple liver masses on abdominal ultrasound. Dynamic liver CT imaging revealed multiple peripheral nodular enhanced mass lesions with delayed centripetal enhancement, and the adjacent collection of high-attenuation fluid along the liver capsule. Abdominal tapping revealed blood in the peritoneal cavity. Primary hepatic epithelioid hemangioendothelioma with spontaneous rupture was finally diagnosed based on a histopathologic examination revealing positive immunohistochemical staining for CD34.

Paraganglioma is a rare neuroendocrine tumor arising from the neural crest, which includes tissues such as the adrenal medulla, carotid and aortic body, organs of Zuckerkandl, and other unnamed paraganglia. The head, neck, and retroperitoneum are the most common sites for paraganglioma. However, paraganglioma of the pancreas is extremely rare. We report our experience of this rare disease. A 70-year old female patient admitted for a pancreas tail mass detected by computed tomography (CT) scan checked for vague left flank pain. CT with contrast enhancement showed a 4.2-cm heterogeneously enhanced lesion in the tail of the pancreas. A well defined ovoid shape mass in left adrenal gland was suggested adenoma. Distal pancreatectomy with left adrenalectomy was performed. Any lymph node enlargement was not found. Pancreas mass did not invade adjacent organ. Microscopic examination with pancreas and adrenal gland revealed that the cells were arranged in a characteristic Zellballen pattern. Immunohistochemical staining revealed positivity for neuron-specific enolase, chromogranin A, synaptophysin, and S-100 protein. On the basis of these findings, we diagnosed the tumor as a paraganglioma of the pancreas and adrenal gland. We report the first case of pancreas paraganglioma in Korea.
