Purpose: Patients with gallbladder cancer tend to have advanced, unresectable tumor at the time of presentation and they face a dismal prognosis in the absence of a standard chemotherapy regimen. This study was performed to evaluate the outcomes of patients with gallbladder cancer and who underwent postoperative gemcitabine-based chemotherapy. Methods: From March of 2001 to February of 2008, a total of 27 patients underwent operation for gallbladder cancer. They underwent two types of gemcitabine-based chemotherapy. One type of regimen was the combined administration of gemcitabine 1,000 mg/㎡ and 5-fluorouracil 200 mg/㎡. The other one was combined administration of gemcitabine 1,000 mg/㎡ and cisplatin 70 mg/㎡. Results: Among the 27 patients, 15 patients were treated with gemcitabine-based chemotherapy and 12 patients were treated with many kinds of the best supportive care without chemotherapy. The median survival was 29.1±2.7 months and 15.7±2.8 months, respectively. The median survival and disease free survival for the gemcitabine based chemotherapy group who received curative resection was 31.6±2.5 and 15.7±3.2 months, respectively. The median survival and disease free survival for the patients without chemotherapy after curative resection was 16.3±2.9 and 15.7±3.2 months, respectively. Conclusion: Patients with gallbladder cancer and who received adjuvant gemcitabine-based chemotherapy had a relatively favorable prognosis. Especially, gemcitabine-based combination chemotherapy could be effective and acceptable for the treatment of gallbladder cancer patients who have undergone curative resection.

We present here a case of recurrent rectal cancer liver metastasis that was managed with ante situm liver resection under total vascular exclusion (TVE) and venovenous bypass with hypothermic perfusion. A 58-year-old man who suffered with rectal cancer liver metastasis was transferred to our hospital in January 2006. A left lateral sectionectomy had been previously performed. Recurrent lesion developed in segments I, IV and VIII one year after the first hepatectomy. The tumor was 5 cm in diameter and it involved the confluence of the hepatic veins and the retrohepatic vena cava. An incomplete tumor-free margin and massive bleeding were expected with performing a conventional liver resection, together with vena cava reconstruction. Therefore, we planned an ante situm liver resection under TVE and venovenous bypass with hypothermic perfusion. After adhesiolysis, hilar dissection was carried out. The inflow to the medial segment was interrupted, and then the liver and inferior vena cava (IVC) were mobilized fully. During controlling the bleeding of a short hepatic vein, we found adhesion of the hepatocaval portion. Therefore, TVE and venovenous bypass were performed along with suprahepatic IVC transection. The long conduit of V5 was preserved during hepatic parenchymal dissection, and the paracaval portion of the caudate lobe was readily detached from the IVC. The suprahepatic IVC was reconstructed after V5 reconstruction with using the saphenous vein. Portal vein anastomosis was then conducted. After reperfusion, an end-to-side anastomosis was performed between the saphenous vein graft and the IVC. Finally, a Roux-en- Y hepaticojejunostomy was carried out. The patient remains well without recurrence 12 months after the last operation.

Purpose: The purpose of this retrospective study was to identify the diagnostic performance of positron emission tomography/computed tomography (PET/CT) compared to conventional modalities, such as ultrasonography (US) and contrast-enhanced computed tomography (CT) in detecting axillary lymph node metastasis (ALNM) in patients with breast cancer. Methods: Two hundred thirty-three consecutive patients diagnosed with primary breast cancer who had not been treated with neoadjuvant chemotherapy and had been examined by US, CT, and PET/CT before surgery were included. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each imaging modality and combinations of modality according to tumor size were obtained, and were compared with the histopathological results of sentinel lymph node biopsy or axillary lymph node dissection. Results: ALNM was confirmed in 32.6% (76/233) of patients. The sensitivity, specificity, PPV, NPV, and accuracy of US for detecting ALNM were 65.8%, 86.6%, 70.4%, 84.0%, and 79.8%, respectively. The sensitivity, specificity, PPV, NPV, and accuracy of CT were 72.4%, 72.6%, 56.1%, 84.4%, and 72.5%, respectively. The sensitivity, specificity, PPV, NPV, and accuracy of PET/CT were 69.7%, 86.0%, 70.7%, 85.4%, and 80.7%, respectively. The combination of US and PET/CT showed the most accurate results with specificity, PPV and accuracy values of 93.6%, 81.5%, and 82.0%, respectively. Conclusion: The diagnostic performance of PET/CT was comparable to that of US and CT. Combination of US and PET/CT could be a reliable strategy for determining preoperative ALNM in patients with operable breast cancer.
