In order to define prognostic factors for advanced stage of nonseminomatous germ cell tumors (NSGCT) of the testis, the authors reviewed 84 patients treated from 1978 through 1985. The survival rate was 51% at 3 years. Patients with elevated seric levels of human chorionic gonadotropin (HCG) and/or alpha-fetoprotein (AFP), or the presence of an abdominal(More)
One hundred fifty-three adult patients with metastatic renal carcinoma were treated over a 12-year period. Five successive chemotherapeutic protocols were used: vincristine or teniposide plus CCNU, elliptinium weekly or monthly, ifosfamide, and lastly, a multidrug regimen with adriamycin, vindesine, cyclophosphamide, cisplatinum, and dacarbazine.

The authors have treated 22 patients with high-risk gestational trophoblastic disease (GTD) by cisplatin-etoposide-containing combinations. Sixteen patients were treated with dactinomycin, platinum, and etoposide combination (APE regimen) and six patients had platinum and etoposide combination (PE regimen). Fourteen patients were treated for resistant or(More)
Despite many advantages that could be gained through belonging to enterprise networks, only a few networks continue running businesses after the governments stop their funding. One of the reasons is the lack of a model that evaluates the benefits from the firm’s point of view. The objective of this work is to develop a model that estimates the benefits in(More)
Nowadays, the advantages of virtual enterprises and collaborative networks are well known by scientists and professional communities. Despite the advantages, only a few networks continue running businesses after stopping the governmental subsides. One of the reasons is the lack of a model that evaluates the benefit from the firm’s point of view. The(More)
Between April 1984 and May 1985, 17 heavily pretreated patients with relapsing or refractory germ cell tumours were treated with cisplatin 40 mg/m2/day, days 1-5; etoposide 350 mg/m2/day, days 1-5; cyclophosphamide 1600 mg/m2/day, days 2-5 and autologous bone marrow transplantation on day 8 as consolidation of conventional salvage chemotherapy. None of the(More)
The effect of different external factors on pollen germination and pollen tube growth is well documented for several species. On the other hand the consequences of these factors on the division of the generative nucleus and the formation of callose plugs are less known. In this study we report the effect of medium pH, 2-[N-morpholino]ethanesulfonic acid(More)
Thirty-eight patients with advanced colorectal adenocarcinoma were entered on a phase II trial of 5-fluorouracil (5-FU) in continuous infusion, using a portable pump. Half of the patients had been pretreated (n = 19) and 16 of them had received intravenous bolus 5-FU alone or in combination. At the first cycle patients received continuous intravenous 5-FU(More)
18 relapses of non seminomatous germ cell cancer of the testis are studied, among a group of 112 patients treated from 1974 to 1978, of which 90 are in complete remission. The study of these cases shows the bad prognosis value of yolk sac tumor component at histological examination. Relapses are more frequent in the stages with lymph node involvement(More)
