Leiomyosarcoma of the inferior vena cava (IVC) is a rare tumor, and it needs complete surgical resection for cure. In addition, the reconstruction of IVC is necessary in many cases. Herein, we indicate the case of a 57-year-old female with leiomyosarcoma in segment I of the IVC, which grew deep into vascular lumen. She underwent complete en bloc resection of the tumor and IVC reconstruction by an artificial pericardium patch.

Hepatic resection (HR) and radiofrequency ablation (RFA) are popular local therapies for early-stage hepatocellular carcinoma (HCC).Alpha-fetoprotein,Lens culinaris agglutininreactive fraction of alpha-fetoprotein,and des-c-carboxy prothrombin are well-known and useful tumor markers for *** positive number status of these tumor markers has recently been demonstrated as beneficial for predicting outcome for HCC patients treated with local *** the normal ranges reported have differed by institution,the positivity of tumor markers is consistent and can easily be *** and Wakayama's group clearly demonstrated the following:1) Regardless of the degree of tumor stage,a triple-positive tumor marker profile can predict poor outcome in HCC patients undergoing HR;2) For RFA alone,HCC patients with double-and triple-positive status,having less than three lesions and lesions ≤3 cm in diameter show comparably insufficient outcomes;3) For HCC patients with lesions ≤5 cm in Child-Pugh grade A,HR is preferred over RFA;4) Microvascular invasion rates increased even in the double-positive patients,while poorly differentiated HCC was frequently observed only in the triple-positive patients;and 5) RFA with chemoembolization,anatomical liver resection,and postoperative adjuvant chemoembolization or hepatic arterial chemotherapy might improve the outcome for patients with highly malignant HCC with multiple positive tumor ***,the impacts of these therapies still need to be evaluated in prospective comparative studies.

Pancreatic pseudocyst-portal vein fistulae are extremely rare, and cause serious complications, including life-threatening sepsis. We report a 57-year-old man with pancreatic pseudocyst who was admitted to our hospital complaining of prolonged abdominal pain. A pancreatic duct tube was placed into the main pancreatic duct, as the pseudocyst was communicated to the pancreatic duct. He fell into septic shock state two weeks later. An ultrasonography-guided percutaneous drainage of the pseudocyst was performed. The amylase level of drained pus was 80,000 U/l. Pancreatic pseudocyst-portal vein fistula was demonstrated by fisterography. Symptoms disappeared immediately after drainage. No recurrence was observed afterward.

AIM: To evaluate prognoses after cutaneous metastases, derived from pancreatic cancer. METHODS: We treated two patients with cutaneous metastases from pancreatic cancer. We reviewed 40 reported patients in addition to our cases and analyzed clinical features of cutaneous metastases from pancreatic cancer. RESULTS: The median survival time (MST) was 5 mo after diagnoses of cutaneous metastases. The cumulative 2-year survival rate was 3.5%. The most frequent site of cutaneous metastases was the umbilicus. The MST of patients who were treated with chemotherapy or chemoradiotherapy (CRT) was 6.5 mo, which was statistically longer in comparison to patients without treatment. Prognoses of cutaneous metastases are similar to other metastatic sites from pancreatic cancer. Receiving chemotherapy or CRT was the only prognostic factor of cutaneous metastases from pancreatic ***: The prognoses of cutaneous metastases are similar to other metastatic pancreatic cancers. Receiving chemotherapy or CRT was the only prognostic factor of cutaneous metastases from pancreatic cancer.
