Pancreatic cancer is an aggressive malignancy poten-tially curable with surgical intervention. Following pan-creaticoduodenectomy for suspected pancreatic head malignancy, patients have a high risk for both immedi-ate and delayed problems due to surgical complica-tions and recurrent disease. We report here a patient with pancreatic cancer treated with pancreaticoduode-nectomy who developed recurrent disease resulting in obstruction of the afferent limb. The patient developed biliary obstruction and cholangitis at presentation. Her biliary tree failed to dilate which precluded safe percu-taneous biliary decompression. During surgical explo-ration, she was found to have a dilated afferent limb at the level of the transverse mesocolon. The patient underwent decompression of the afferent limb as well as the biliary tree using a venting gastrojejunostomy to the blind loop. This represents a novel surgical ap-proach for management of this complicated and diffi-cult problem.

A 68-year-old Caucasian man with hepatitis C virus- related cirrhosis was admitted to our Unit in February 2010 for a diagnostic evaluation of three centimetric hypoechoic focal liver lesions detected by regular sur- veillance ultrasound. The subsequent computer tomog- raphy(CT) led to a diagnosis of unifocal hepatocellular carcinoma(HCC) in Ⅵ hepatic segment, defined the other two nodules in the Ⅵ and Ⅶ segment as sus- pected metastases, and showed a luminal narrowing with marked segmental circumferential thickening of the hepatic flexure of the colon. Colonoscopy detected an ulcerated, bleeding and stricturing lesion at the hepatic flexure, which was subsequently defined as ad- enocarcinoma with a moderate degree of differentiation at histological examination. Finally, ultrasound-guided liver biopsy of the three focal liver lesions confirmed the diagnosis of HCC for the nodule in the Ⅵ segment, and characterized the other two lesions as metastases from colorectal cancer. The patient underwent laparo- tomic right hemicolectomy with removal of thirty-nine regional lymph nodes(three of them tested positive for metastasis at histological examination), and simulta- neous laparotomic radio-frequency ablation of both nodule of HCC and metastases. The option of adju- vant chemotherapy was excluded because of the post- surgical onset of ascites. Abdomen CT and positron emission tomography/CT scans performed after 1, 6 and 12 mo highlighted a complete response to treat- ments without any radiotracer accumulation. After 18 mo, the patient died due to progressive liver failure. Our experience emphasizes the potential coexistence of two different neoplasms in a cirrhotic liver and the complexity in the proper diagnosis and management of the two tumours.

Deformable image registration (DIR) has been an important component in adaptive radiotherapy (ART). Our goal was to examine the accuracy of ART using the dice similarity coefficient (DSC) and to determine the optimal timing of replanning. A total of 22 patients who underwent volume modulated arc therapy (VMAT) for head and neck (H&N) cancers were prospectively analyzed. The planning target volume (PTV) was to receive a total of 70 Gy in 33 fractions. A second planning CT scan (rescan) was performed at the 15th fraction. The DSC was calculated for each structure on both CT scans. The continuous variables to predict the need for replanning were assessed. The optimal cut-off value was determined using receiver operating characteristic (ROC) curve analysis. In the correlation between body weight loss and DSC of each structure, weight loss correlated negatively with DSC of the whole face (rs = -0.45) and the face surface (rs = -0.51). Patients who required replanning tended to have experienced rapid weight loss. The threshold DSC was 0.98 and 0.60 in the whole face and the face surface, respectively. Patients who showed low DSC in the whole face and the face surface required replanning at a significantly high rate (P < 0.05 and P < 0.01). Weight loss correlated with DSC in both the whole face and the face surface (P < 0.05 and P < 0.05). The DSC values in the face predicted the need for replanning. In addition, weight loss tended to correlate with DSC. DIR during ART was found to be a useful tool for replanning.

Introduction: Prolonged immuno-suppressed status promised to induce internal growth of malignant cell and infectious agent, yet, only a small part of affected individuals seek medical attention or berried by commercially over-flowed fake information. Several studies have described complementary and alternative medicine as effective strategies for improving anti-infectious agent including malignant cell. The purpose of this study was to investigate the effect of a fermented herbal decoction (FHD) both in vitro and in vivo to malignant cells and microorganism by regulating leukocyte subset proportioning FHD as dietary material. Methods: In this approach of alternative study, selective anti-cancer effect by fermented decoction was tried to show first in vitro system both, cancer cell and virus strain. The fermented herbal decoction consisting of 80 sorts of herbs and fruits. The selective toxicity was set up and then for immunological factors in animal and human. The most important factor is to reduce side effect for a normal cell. Results: First, FHD was proved as safe by animal test. FHD regulated also the proportion of granulocyte and lymphocyte ratio both animal and human. In vitro culture showed selective toxicity by FHD against human melanoma and leukemia cell line but reduced toxicity was showed by normal cell line. As for the anti-virus activity, anti-virus effect was tested on the feeder layer of human fibroblast cell, after 9 days of culture. Second, FHD inhibits colon cancer growth in 3-methylholanthrene induced cancer in rat. Conclusion: The present results suggest that our fermented herbal decoction showed selective anti-cancer activities and anti-virus activities, together with the regulative effect on the immune system.
