Prompted by a unique case of an ectomesenchymal chondromyxoid tumor(ECT) of the palate in a 54-year-old female, we reviewed the English and German literature on this entity until the end of 2016 using Pub Med. The search produced 74 lingual cases with a nearly equal sex distribution and a mean age of 39.3 years, and two extra-lingual cases sharing histological and immunohistological features including nodular growth, round, fusiform or spindle-shaped cellular architecture, and chondromyxoid *** showed the majority of cases to be positive for glial fibrillary acidic protein(GFAP), S-100 protein,glycoprotein CD57, pancytokeratin (AE1/AE3), and smooth muscle actin(SMA); in isolated cases there was molecular-genetic rearrangement or gain of Ewing sarcoma breakpoint region 1 (EWSR1) but no rearrangement of pleomorphic adenoma gene 1 (PLAG1). At present, ectomesenchymal cells that migrate from the neural crest are considered to play a pivotal role in tumor *** cases had a benign course, although there were three recurrences. Because of the rarity of this tumor and the need for differential diagnostic differentiation from myoepithelioma and pleomorphic adenoma, both oral surgeons and pathologists should be aware of this entity.

Patients without hepatocellular carcinoma progression after transarterial chemoembolization benefit from liver transplantation

引用

World Journal of Gastroenterology 2007年第5期13卷 761-767页

作者： Aiman Obed Alexander beham Kerstin Püllmann Heinz Becker Hans J Schlitt Thomas Lorf Department of Surgery University of Regensburg Regensburg 93053Germany 不详 Department of Surgery University of Goettingen Goettingen 37073 Germany

AIM： To assess the outcome of patients, who underwent transarterial chemoembolization （TACE） for hepatocellular carcinoma （HCC） and subsequently liver transplantation （OLT） irrespective of tumor size when no tumor progression was observed. METHODS： Records, imaging studies and pathology of 84 patients with HCC were reviewed. Ten patients were not treated at all, 67 patients had TACE and 35 of them were listed for OLT. Tumor progression was monitored by ultrasound and AFP level every 6 wk. Fifteen patients showed signs of tumor progression without transplantation. The remaining 20 patients underwent OLT. Further records of 7 patients with HCC seen in histological examination after OLT were included. RESULTS： The patients after TACE without tumor progression underwent transplantation and had a median survival of 92.3 too. Patients, who did not qualify for liver transplantation or had signs of tumor progression had a median survival of 8.4 mo. The patients without treatment had a median survival of 3.8 mo. Independent of International Union Against Cancer （UICC） stages, the patients without tumor progression and subsequent OLT had longer median survival. No significant difference was seen in the OLT treated patients if they did not fulfill the Milan criteria. CONCLUSION： Selection of patients for OLT based on tumor progression results in good survival. The evaluation of HCC patients should not only be based on tumor size and number of foci but also on tumor progression and growth behavior under therapy.

Survival benefit in patients after palliative resection vs non-resection colon cancer surgery

引用

World Journal of Gastroenterology 2006年第41期12卷 6634-6638页

作者： a beham M Rentsch K Püllmann L Mantouvalou H Spatz HJ Schlitt A Obed Department of Surgery University of RegensburgGermany

AIM: To evaluate survival in patients undergoing pallia- tive resection versus non-resection surgery for primary colorectal cancer in a retrospective analysis. METHODS: Demographics, TNM status, operating de- tails and survival were reviewed for 67 patients under- going surgery for incurable colorectal cancer. Palliative resection of the primary tumor was performed in 46 cases in contrast to 21 patients with non-resection of the primary tumor and bypass surgery. Risk factors for post- operative mortality and poor survival were analyzed with univariate and multivariate ***: The two groups were comparable in terms of age, gender, preoperative presence of ileus and tumor stage. Multivariate analysis showed that median survival was significantly higher in patients with palliative resec- tion surgery (544 vs 233 d). Differentiation of the tumor and tumor size were additional independent factors that were associated with a significantly poorer survival rate. CONCLUSION: Palliative resection surgery for primary colorectal cancer is associated with a higher median survival rate. Also, the presence of liver metastasis and tumor size are associated with poor survival. Therefore, resection of the primary tumor should be considered in patients with non-curable colon cancer.

5-Fluorouracil-related enhancement of adenoviral infection is Coxsackievirus-adenovirus receptor independent and associated with morphological changes in lipid membranes

引用

World Journal of Gastroenterology 2006年第32期12卷 5168-5174页

作者： Chiara Cabrele Mandy Vogel Pompiliu Piso Markus Rentsch Josef Schroder Karl W Jauch Hans J Schlitt Alexander beham Department of Surgery Clinic of the Regensburg University Franz-Josef-Strauss-Allee 11D-93053RegensburgGermany

AIM： To evaluate the mechanism underlying the effects of 5-Fluorouracil （5-FU） on adenoviral infection. METHODS： Low and high Coxsackievirus-Adenovirus Receptor （CAR） expressing human colon carcinoma cell lines were treated with 5-FU and two El-deleted adenoviral constructs, one transferring GFP （Ad/CMV- GFP） the other bax （Ad/CEA-bax）. The number of infected cells were monitored by GFP expression. To evaluate the effects of 5-FU in a receptor free system, Ad/GFP were encapsulated in liposomes and treated with 5-FU. Ad/GFP release was estimated with PCR and infection of 293 cells with the supernatant. Electron microscopy of the Ad5-GFP-liposome complex was made to investigate morphological changes of the liposomes after 5-FU. RESULTS： Infection rates of all cell lines increased from 50% to 98% with emerging 5-FU concentrations. The enhanced viral uptake was independent of the CAR expression. Additionally, 5-FU treated liposomes released 2-2.5 times more adenoviruses. Furthermore, 5-FU- treated liposomes appeared irregular and porous-like. CONCLUSION： adenoviral uptake is enhanced in the presence of 5-FU irrespective of CAR and is associated with morphological changes in membranes making the combination of both a promising option in gene therapy.
