    Notes: Abstract Backgrounds: Patients with cirrhosis of the liver sometimes are candidates for esophagectomy with extensive lymphadenectomy. Materials and Methods: Of 271 patients with primary esophageal carcinoma, 19 patients (7.0%) had pathologically proven cirrhosis of the liver. Among those, 18 patients underwent esophagectomy with extensive lymph node dissection. Clinicopathologic characteristics of these 18 patients were retrospectively investigated. Results: Pathological T stages were pT1 in 3 patients, pT2 in 9 patients, pT3 in 2 patients, and pT4 in 4 patients. Hepatitis C virus antibody was positive in 1 patient, and 14 patients were alcoholics. Three patients had cryptogenic cirrhosis. Seven patients were classified as Child- Turcotte B and 11 were Child-Turcotte A. Three patients had ICG-R 15 over 30%. Fifteen patients (83.3%) developed a total of 35 postoperative complications. Three patients currently are alive without recurrence. Fifteen patients have died: 7 from cancer recurrence; 5 of causes unrelated to esophageal cancer; and 3 of operative death (operative mortality: 16.7% in 18 cirrhotic patients vs. 5.7% in 227 non-cirrhotic patients; P 5 .102). The 1- and 3-year survival rates for 18 resected cirrhotic patients were 50% and 21%, respectively, and those for 227 resected non-cirrhotic patients were 67% and 42%, respectively (P 5 .051). When operative deaths were excluded from the analysis, the 1- and 3-year survival rates for 15 cirrhotic patients were 60% and 25%, respectively, whereas those for 214 non-cirrhotic patients were 68% and 43%, respectively (P 5 .271). Conclusion: Although cirrhosis has a high morbidity and mortality rate, Child-Turcotte A and B cirrhosis may not contraindicate curative esophagectomy for esophageal carcinoma. However, these patients need meticulous perioperative care to avoid postoperative complications.

    Notes: Abstract Background: Previous studies indicate that gastric carcinomas express Fas ligand and downregulate Fas to escape from the host immune attack; however, the prognostic importance of Fas/FasL expression in this tumor is yet to be evaluated. Methods: Specimens from 87 gastric carcinoma patients of different stages treated in a defined period with curative intent were evaluated for apoptosis, Fas, FasL, and CD8 expression using an immunohistochemical method. Results: The percentage of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive apoptotic cells expressed as apoptotic index (AI) was higher in 43 patients when the cut-off value was set at the median value. There were no significant correlations between AI and clinicopathologic parameters. Thirty-nine patients showed a high number of CD81 cells within cancer nests. Positive FasL and Fas expression was seen in 53 and 72 patients, respectively. CD8 and FasL expressions were related only to patients’ age. Fas expression had significant correlations with tumor invasion and Lauren classification. There were significant direct correlations between AI and number of nest CD81 cells and between AI and grade of Fas expression. Apoptotic index, pT stage, CD8 expression, and Fas expression were identified as independent prognostic factors. Conclusions: Spontaneous apoptosis in gastric carcinoma may be an independent prognosticator for survival and is significantly influenced by tumor Fas expression and number of nest CD81 cells.

    Ethanol productions from D-xylose and cellobiose by Kluyveromyces cellobiovorus (1985)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Yeasts capable of fermenting both D-xylose and cellobiose to ethanol were screened. Of 213 species of yeasts surveyed, Kluyveromyces cellobiovorus sp. nov., a new species belonging to genus of Kluyveromyces, was selected as the sole strain. This strain accumulated 32, 22, and 19 g/L of ethanol from 8% glucose, D-xylose, and cellobiose, respectively. It was also shown that this strain produced ethanol from the enzymatic bagasse hydrolysate containing hexoses and pentoses more efficiently than Saccharomyces cerevisiae.
