Ninety-four consecutive patients with chronic myelogenous leukemia in first clinical chronic phase, median age of 34.0 years (range, 6.8 to 52.4 years), with a histocompatible sibling donor, were treated with fractionated total body irradiation (1,320 cGy) and high-dose etoposide (60 mg/kg) followed by allogeneic bone marrow transplantation (BMT). The median time from diagnosis to BMT was 7.0 months (range, 2.3 to 72.0 months). Sixty patients were treated before BMT with hydroxyurea alone, four patients with busulfan alone, one patient with interferon alone, and the other 29 patients were treated with various combinations of these drugs. Cumulative probabilities of overall survival, event- free survival, and relapse at 5 years were 73%, 64%, and 14%, respectively. The median follow-up time for surviving patients was 38 months, ranging from 12 to 88 months. By stepwise Cox regression analysis, significant prognostic variables were age at transplant, acute graft-versus-host disease > or = grade II, cytomegalovirus- associated interstitial pneumonitis, and years from diagnosis to BMT. 相似文献

Metastatic renal cell carcinoma (RCC): Spontaneous regression,long-term survival and late recurrence 总被引:2,自引:0,他引:2

We report 4 cases of metastatic renal cell carcinoma (RCC) with long-term survival either following radical nephrectomy alone or in combination with radio- or hormonal therapy. Two patients with lymph node metastases showed a long-term survival of 12 or more years following radical tumour nephrectomy (with lymphadenectomy) and radiotherapy. One of them exhibited a histologically proven tumour recurrence nearly 12 years after primary surgical treatment and died shortly later; the other one is still without any evidence of metastatic disease. Two other patients exhibited spontaneous regression of pulmonary metastases: one regression occurred after radical tumour nephrectomy alone, the other one after successful primary hormonal treatment and subsequent radical tumour nephrectomy. The following important aspects are emphasized: 1. Renal cell carcinoma is a very unpredictable tumour. Once the diagnosis of renal cell carcinoma is proved, a patient can never be considered cured. 2. Although adjuvant palliative nephrectomy has produced contradictory results in several reports, radical tumour nephrectomy either alone or in combination with other adjuvant therapies such as radiotherapy, hormonal or immunological treatment, can be worthwhile. Cases with long-term survival and spontaneous regression of distant metastases are proof of this. Besides, if carefully selected, the mortality rate of different adjuvant therapies is not significantly higher in patients with metastatic disease than in patients without metastases. The world literature on this subject is reviewed. 相似文献

This study reviews eight patients, 39–63 years old, with tumor-related obstruction of the inferior vena cava (IVC) extending into the right atrium (n=5) and ventricle (n=3). Five patients suffered from renal cell carcinoma, 3 from sarcomatous disease. The general approach was a median sternotomy and laparotomy with hypothermic circulatory arrest (17.0–20.5°C; 23–46 min) in six patients, while in two patients, the IVC was clamped sequentially under moderate hypothermia and extracorporeal circulation. Four patients had tumor infiltration of the IVC necessitating partial caval resection. In three, the IVC was reconstructed by fabric patches or tubular prothesis. In one patient, the continuity of the IVC was interrupted permanently. Three patients underwent nephrectomy during the same procedure, two before and one after IVC disobliteration. In one patient each, pulmonary embolectomy and intrahepatic IVC stenting were performed. Two patients died early, one due to uncontrollable hemorrhage the other due to non-cardiogenic pulmonary edema. Six patients were discharged in good physical condition and are still alive at a mean follow-up of 24 months. Five patients have since remained free of recurrence, one patient underwent three further surgical interventions for bone metastases. We feel that IVC desobliteration is feasible in selected cases with extended tumor-related obstruction with an acceptable early risk and late outcome. 相似文献

Objectives: To analyze risk factors, management, histology, and outcome of bilateral testicular germ cell tumors (TGCT) based on a 25‐year single center experience. Methods: Out of 612 patients treated for TGCT between 1982 and 2007, 17 (3%) were found to have bilateral disease. Data of these patients were reviewed and analyzed. Results: Eleven patients (65%) were identified with metachronous and 6 (35%) with synchronous bilateral TGCT. One patient had a cryptorchism in childhood. Patients with metachronous bilateral disease presented at lower stages than those with synchronous bilateral disease (stage I: 82% vs 33%, P = 0.02). In metachronous bilateral TGCT, the interval between the tumors ranged from 4 months to 25 years with a median of 47 months. The risk of developing a TGCT in the contralateral testicle was 26‐fold higher than the a‐priori risk for a healthy individual to develop TGCT. Overall, 74% of the bilateral tumors were seminomas and >50% of the patients had similar histology on both sides. After a median follow up of 121 months for patients with synchronous and 95 months for patients with metachronous bilateral TGCT, all patients were alive with no evidence of disease. Conclusions: Most bilateral TGCT develop metachronously and are seminomas. Although patients with synchronous bilateral disease present at higher stages, both synchronous and metachronous bilateral TGCT carry a similar, excellent prognosis. Patients with unilateral TGCT require careful long‐term monitoring of the remaining testicle due to a 26‐fold increased risk of contralateral disease and a potentially long risk interval of up to 25 years. 相似文献

Summary A ureteroneocystostomy (UNC) was carried out on 32 dogs. A standardised measurement of flow across the ureterovesical anastomosis revealed a significant obstruction on the day of the operation itself and on the first 5 days after the operation. On the 1st, 7th and 28th day after the operation there was no significant reduction in either tubulosecretory or glomerular function on the operated and non-operated kidneys. 相似文献
