RESUMO
The present study sought to identify the therapeutic efficacy of adjuvant external beam radiotherapy (EBRT) for carcinomas of the extrahepatic bile duct (EHBD) and gallbladder. Twenty-one patients with pathologically verified EHBD carcinoma and 18 patients with gallbladder carcinoma were analyzed retrospectively by Cox regression analysis for predictors of survival. The overall 5-year survival rates after resection were 33% for EHBD carcinoma and 56% for gallbladder carcinoma. The overall 5-year survival rate for EHBD carcinoma was 60% in 8 patients without microscopic residual disease (R0), 15% in 9 patients with microscopic residual tumor (R1), and 0% in 4 patients with macroscopic residual tumor (R2). The overall 5-year survival rate of gallbladder carcinoma patients was also decreased with R status equal to 73%, 40%, and 0% for R0, R1 and R2, respectively. Adjuvant radiotherapy significantly improved the 5-year survival rate in 7 patients with R1 disease of EHBD carcinoma (P = .035), compared with survival in 2 patients who underwent resection alone. However, no significant difference was noted in the 5-year survival rate between the resection plus EBRT group and the resection alone group for gallbladder carcinoma. Multivariate analysis revealed that histopathologic grade (G) was an independent predictor of survival for EHBD carcinoma and that direct invasion of liver parenchyma was a predictor of survival for gallbladder carcinoma. This study suggests that curative resection provides the best survival for patients with EHBD and gallbladder carcinoma, and that radiotherapy may play a beneficial role in controlling local-regional residual EHBD carcinoma tumors. However, new strategies for adjuvant therapy are needed to improve survival in patients with gallbladder carcinoma.

Effects of radiation therapy for lymph node metastases from gastric cancer were retrospectively analyzed. The radiation sites were residual paraaortic lymph node involvement and postoperative recurrent lymph node metastases in 10 patients. The size of lymph node swelling was decreased in 6 (60%) patients after radiation therapy using liniac. Complaints due to lymph node metastases such as pain and edema of extremities were voiced by 7 patients. These complaints were eventually relieved or disappeared in all 7 patients. There were no severe adverse effects during radiation therapy, and 7 patients (70%) could shift to home care. One-year and 3-year survival rates were 20 and 10%, respectively. Radiation therapy for lymph node metastases from gastric cancer was chiefly effective in relieving complaints. Although it is unclear whether radiation therapy can improve the survival rate, these results suggest that radiation therapy could be one of the most useful locoregional therapies for paraaortic lymph node involvement and recurrent lymph node metastases from gastric cancer.

In contrast to malignant lymphomas or skin cancer, smooth muscle tumors including leiomyosarcoma are rarely associated with transplant recipients. We herein present a 33-year-old woman with end-stage renal disease who received a transplant at 27 years of age. Four years after the transplantation, at age 31, she underwent a mastectomy because of primary right breast cancer, which was found to be a 5-mm-sized mucinous carcinoma with no regional lymph node metastasis. Six years after the transplantation, a liver tumor was unexpectedly discovered. An explorative laparotomy revealed a well-encapsulated tumor occupying the posterior portion of the right lobe of the liver. The patient underwent a posterior segmentectomy. Histologically, the tumor possessed intermingling fascicles of spindle cells with eosinophilic cytoplasm and elongated nuclei. Based on an immunohistochemical examination, the tumor cells were positive for the muscle-associated antibody. In addition, RNA probes for Epstein-Barr virus were negative based on in situ hybridization. The histologic, immunohistochemical findings were considered to be diagnostic for leiomyosarcoma, which is a low-grade malignancy. Two years after surgery, the patient is doing well with no recurrence of liver tumors or breast cancer.

Major gastrointestinal bleeding is a rare manifestation of intestinal Behçet's disease. We report herein the case of a 64-year-old man with intestinal Beh,et's disease complicated by myelodysplastic syndrome who suffered massive hemorrhage. Colonoscopy demonstrated ulceration of the entire colon from the cecum to the rectum, characterized by punched-out ulcers. Angiography demonstrated apparent extravasation of contrast material in the terminal ileum, and embolization was not successful. Continued and massive bleeding necessitated surgical resection of the involved segment of ileum; however, massive bleeding recurred. Re-endoscopy showed oozing hemorrhage from the multiple colon ulcerations. Intra-arterial prednisolone injection therapy was given, following which the melena gradually subsided and completely stopped within a few days.
