The hepatitis B virus (HBV) infection and its resulting hepatic abnormalities are very high in prevalence among the Taiwan population. They also seem to compose a major problem to patients subjected to bone marrow transplantation (BMT) due to intensive chemoradiotherapy. In this study, the sera of 42 patients were investigated before and after BMT to detect the presence of HBV markers and to test their liver function (LF). Being followed-up for 3–12 months after BMT, 12 out of 27 were found to have altered HBV markers according to the classification of the following: seroconversion of HBsAg, clearance of HBsAb, appearance of HBeAg, clearance of HBeAb, and acute hepatitis. Thirty-seven out of 42 patients (88.1%) were found in routine LF test to develop one or more abnormality; however, 90% of them turned normal within one year after BMT. Only one patient died of complications associated with fulminant hepatitis. In conclusion, the previous hepatic damage from HBV infection appears unlikely to increase the risk of posttransplant morbidity and mortality.

BACKGROUND Bone marrow transplantation (BMT) is effective treatment for many hematologic disease, but performed in a population with a high endemic hepatitis B virus carrier rate, the incidence of liver function impairment and fulminant hepatitis (FH) is expected to be raised. METHODS Forty-three hepatitis B virus carriers received high-dose chemotherapy and BMT, 32 patients received an allogeneic graft, and 11 patients autologous marrow. Acute graft-versus-host disease prophylaxis consisted of methotrexate on day 1, 3, 6, and 11 and cyclosporine for 6 months. RESULTS After a median follow-up period of 68 months (range: 1-11.5 years), 26 (81.3%) allogeneic BMT patients developed impaired liver function (LF), 5 progressed to FH on day 93, 169, 170, 180, and 468, respectively, and died after an average of 13.8 days (range: 1-45 days). Whereas only 4 (36.4%) autologous BMT patients developed impaired LF, and none FH. Impaired LF (P=0.026, chi-square), and FH (odds ratio=12.86, P=0.009 for coefficient) were significantly related to an allogeneic marrow graft, and the timing of liver function impairment coincided with cyclosporine withdrawal. Hepatitis B surface antigen (HbsAg) disappeared from the serum in 4/14 (28.6%) patients receiving a marrow graft from an HbsAg+ donor. HbsAg was not detected in the serum after BMT in 2/11 (18.2%) autologous BMT patients. CONCLUSIONS Hepatitis B virus carriers receiving a marrow graft from an HbsAg+ donor have a significantly increased risk of FH.

To investigate the causes of impaired liver function (LF)* after BMT, 88 patients were included for analysis of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, transplant methods, preconditioning regimens, and graft-versus-host disease (GVHD). Fifty of them (56.8%) developed abnormal LF after BMT and among them, 29 (32.9%) developed chronic hepatitis (CH). By univariate analysis, HCV infection, pretransplant abnormal LF, allogeneic BMT, and preconditioning regimen with total body irradiation were all significantly related to higher incidence of post BMT impaired LF. However, only HCV infection, pretransplant abnormal LF, and acute GVHD were associated with higher incidence of CH. By multivariate logistic regression analysis, HCV infection and pretransplant abnormal LF were the two most significant interpreters for abnormal LF, especially for CH (odds ratios: 7.86 and 4.735, respectively) after BMT. Although the incidence of abnormal LF was found high in this study, there was no significant disadvantage in terms of survival for patients who developed abnormal acute and chronic liver function after BMT. However, a long-term follow-up is needed to evaluate survival pathology of CH, such as liver cirrhosis and hepatoma.

A 22-year-old woman had a normal full-term delivery 6 years after a successful allogeneic bone marrow transplantation (BMT) for acute myeloid leukemia (AML). Conditioning therapy consisted of cyclophosphamide (120 mg/kg) and total body irradiation (TBI) to a total of 1575 cGy in seven fractions (225 cGy × 7, at a dose rate of 3.5 cGy/min). Graft-versus-host disease prophylaxis was with methotrexate and cyclosporin A. Grade I acute GVHD developed after BMT but there was no chronic GVHD. She became amenorrhoeic after BMT and serial gonadal testing indicated hypergonadotrophic hypogonadism. She became pregnant and delivered a full-term, healthy baby 6 years after BMT. Successful pregnancy after TBI of more than 1200 cGy is extremely rare. This case, to the best of our knowledge, is the second patient who received a higher dose of TBI (1575 cGy) to have a successful pregnancy. This and previous reports indicate that normal pregnancy is possible after BMT with TBI in excess of 1200 cGy.

PURPOSE The feasibility of adjuvant cisplatin, methotrexate and vinblastine chemotherapy was evaluated in Taiwanese patients with invasive transitional cell carcinoma at high risk for recurrence. MATERIALS AND METHODS We assigned 56 patients with high risk transitional cell carcinoma (vascular or lymphatic invasion in the primary tumor, poorly differentiated stage P2, P3, P4 or N+ and M0) to receive adjuvant chemotherapy after radical urological surgery. The chemotherapy consisted of 40 mg./m.2 methotrexate and 4 mg./m.2 vinblastine on days 1 and 8, and 100 mg./m.2 cisplatin on day 2 given in 6 courses at 21-day intervals. RESULTS Median followup was 44 months. An average of 4.63 cycles of chemotherapy was administered. The median actual survival was 44 months, and the 1 and 3-year survival probabilities were 92% and 50%, respectively. The median disease-free survival was 15.5 months, and the 1 and 3-year disease-free survival probabilities were 66% and 28%, respectively. Only 5 (9%) and 1 (2%) patients had grades 3 and 4 leukopenia, respectively, and none died of sepsis. CONCLUSIONS The use of adjuvant cisplatin, methotrexate and vinblastine chemotherapy in patients with invasive transitional cell carcinoma at high risk for recurrence is feasible with tolerable toxicity but randomized controlled trials will be required to assess the benefit.

A total of 21 multiply transfused patients with severe aplastic anemia (SAA) were treated with bone marrow transplantation between March 1985 and September 1990: 20 allogeneic and one syngeneic transplants. A positive response in mixed lymphocyte culture (MLC) was also noted in 7 allogeneic recipients. Pregraft conditioning included high-dose cyclophosphamide (CY) 200 mg/kg over 4 consecutive days, followed by 300 cGy total-body irradiation the day before BMT. Seventeen patients older than 14 years received additional donor buffy-coat cells infusion for 5 days posttransplant. A combination of methotrexate and cyclosporine was used for prophylaxis of graft-versus-host disease. Seventeen patients were alive with a functional graft, and Kaplan-Meier product limit estimates showed a 80.95% probability of survival at 67.7 months. There were 4 deaths: two died of primary graft failure, one from secondary rejection, and the other from chronic GVHD-related complications. Acute GVHD, grade I was noted in only one patient (5.6%). In contrast, chronic GVHD was observed in 10 out of 18 (55.6%) evaluable patients. Venoocclusive liver disease and interstitial pneumonitis were not diagnosed. Our findings indicate that the combination of CY/TBI/BC is well tolerated and results in a low incidence of graft failure/rejection in multiply transfused Chinese patients who received transplants for SAA. The MTX/CsA combination was confirmed as being remarkable in reducing the incidence and severity of acute GVHD. For patients with SAA under the age of 40, with an HLA-identical sibling, we highly recommend BMT as the treatment of choice.

In Taiwan, as in other areas of Asia, the incidence of chronic lymphocytic leukemia (CLL) is low. A retrospective analysis was conducted to elucidate the clinicopathologic features of CLL patients in Taiwan. Of the 47 cases of CLL enrolled in this study, 45 were immunophenotyped as B-CLL; the other 2 were T-CLL. It was found that the lower the Binet and Rai stages of the B-CLL, the longer patients survive (p = 0.0131 and 0.0142, respectively). Univariate analysis showed that fatigue, splenomegaly, hepatomegaly and anemia are associated with poor survival with p values of 0.0203, 0.0184, 0.0001 and 0.171, respectively. By multivariate analysis with Coxs proportional hazard model, hepatomegaly and decrease in body weight were the two most significant predictors of survival. However, molecular parameters of kappa or lambda immunoglobulin (Ig) gene rearrangement or double allele rearrangement of Ig gene did not significantly increase the predictability of the prognosis.

The efficacy and toxicity of a combination of etoposide 100 mg/m2/day iv on day 2-4, leucovorin 300 mg/m2/day iv, and 5-FU 500 mg/m2 day iv on day 1-5 every 4 weeks were assessed in 21 patients with advanced gastric cancer with measurable or evaluable diseases. Eight patients had an objective response, including 3 in CR. The overall response rate was 38.1% (95% CI 33.4-42.8%). Five of 8 patients who exhibited locally advanced and unresectable diseases had an objective response (2 CR, 3 PR). The response rate in patients with metastatic disease was 23.0% (95% CI 14.4-31.6%). The median progression-free interval and overall survival time were 7 and 10 months, respectively. The most frequent side effect was alopecia (Gr I/II 71.4%). No treatment-related death occurred. Modified ELF is a relatively effective and tolerable combination regimen for advanced gastric cancer and can be safely administered to elderly patients and patients with systemic diseases.

SummaryThe CMV (cisplatin, methotrexate, and vinblastine) and M-VAC (methotrexate, vinblastine, doxorubicin, and cisplatin) regimens were used to treat 19 patients with advanced transitional-cell carcinoma (TCC) of the urothelial tract. In the CMV group, the partial response rate was 45.5% and the mean response duration was 6.3 months. No complete response was obtained in our series. The median duration of survival was 15.8 and 8.3 months in responders and nonresponders, respectively. The toxic symptoms included one case of sepsis and three cases of renal toxicity. However, nausea and vomiting were experienced by most patients and required the administration of antiemetics. In the M-VAC group, the median duration of survival for responders was longer than that of nonresponders (>10.2 vs 7.2 months), although the number of patients was too small for this difference to reach statistical significance. The toxic symptoms included one case of sepsis, two cases of renal toxicity, and nausea and vomiting in most patients. Bone metastasis in three patients did not respond to chemotherapy (CMV), a finding that is compatible with the results reported by other investigators. In summary, chemotherapy with the CMV or M-VAC regimen was effective in improving the response rate of patients. However, the duration of response was short, toxicity was severe in some cases, and the efficacy against bone lesions was poor. These problems must be solved to improve the outcome of patients with TCC following chemotherapy with the CMV or M-VAC regimens.
