    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 Because myasthenia gravis (MG) is frequently associated with thymoma, in this study the histological patterns of thymomas from 11 patients with MG (group A) were compared with those from 8 patients without MG (group B). An immunohistochemical examination was also conducted to determine whether the thymoma associated with MG is the site where autoantibodies are produced or secreted. Lymphoid follicles (LFs) and medullary differentiation (MD) were histologically evident only in group A in 4 and 5 patients, respectively, but were completely absent in group B. Moreover, an elevated serum antiacetylcholine receptor antibody titer was found in group A. Typical LFs were histologically and phenotypically similar to the lymph follicles seen in reactive lymph nodes. The number of cells expressing the B-cell antigen differed between groups A and B in terms of IgM- or IgD-bearing cells in the mantle zones and LNI-positive cells in the germinal centers of Us. Thus, it is thought that LFs consist of B cells under stimulatory conditions and that these B cells may have the potential to produce autoantibodies in MG; however, since the differentiation of these Ig-bearing cells to plasma cells was hardly evident, the thymoma itself is possibly not the site of autoantibody production or secretion in patients with MG.
