Current views on intravesical treatment and chemoprophylaxis of superficial bladder cancer. The present role of epirubicin and doxorubicin.
1993
Since 1972, a large number of studies have shown that intravesical treatment with doxorubicin (adriamycin) is effective against carcinoma in situ and multiple papillary tumors. Furthermore, it significantly reduces the recurrence rate after transurethral resection. Its efficacy has been compared with that of Bacillus Calmette-Guerin (BCG), which is the only treatment accepted by the US Food and Drug Administration for therapy of carcinoma in situ (Tis). In more recent years, a few studies have been performed using intravesical epirubicin in the hope that different properties of the molecule might enhance the activity of the anthracyclines, but produce fewer and milder side-effects. After we…
Prophylaxis of invasive fungal infections in patients with hematological malignancies and solid tumors
2003
Morbidity and mortality in patients with malignancies, especially leukemia and lymphoma, are increased by invasive fungal infections. Since diagnosis of invasive fungal infection is often delayed, antifungal prophylaxis is an attractive approach for patients expecting prolonged neutropenia. Antifungal prophylaxis has obviously attracted much interest resulting in dozens of clinical trials since the late 1970s. The non-absorbable polyenes are probably ineffective in preventing invasive fungal infections, but may reduce superficial mycoses. Intravenous amphotericin B and the newer azoles were used in clinical trials, but their role in antifungal prophylaxis is still not well defined. Allogene…
Correlation between GP-170 expression, prognosis, and chemoresistance of superficial bladder carcinoma.
2003
To study GP-170 in superficial bladder cancer at initial diagnosis and at recurrence and to evaluate if intravesical chemoprophylaxis modifies the expression of GP-170 in tumor recurrences. GP-170 was retrospectively assessed in 160 patients affected by primary superficial transitional cell carcinoma of the bladder and followed for up to 10 years. Eighty-four patients (52.5%) recurred after transurethral resection (TUR). Adjuvant intravesical chemotherapy after TUR was adopted in 52 patients. The correlations between GP-170 and G-grade, T-category, risk of recurrence and of progression, and adoption of adjuvant intravesical chemotherapy were investigated. The correlations between variations…
Efficacy of caspofungin and itraconazole as secondary antifungal prophylaxis: analysis of data from a multinational case registry
2009
Patients surviving invasive fungal disease (IFD) and needing further antineoplastic chemotherapy are at high risk of recurrent fungal infection. In the absence of randomised controlled trials in this area, secondary prophylactic regimens are diverse. From 448 patients registered with the Multinational Case Registry of Secondary Antifungal Prophylaxis, we performed an analysis of patients receiving caspofungin (CAS) or itraconazole (ITC). All patients had an underlying haematological malignancy and had been diagnosed with an episode of IFD earlier in their course of treatment. Data collected comprised demographics, underlying disease, first episode of IFD, antifungal prophylaxis, incidence a…
Prophylaxis of early bacterial infections after autologous peripheral blood stem cell transplantation (PBSCT): a matched-pair study comparing oral fl…
2005
The safety and efficacy of early bacterial prophylaxis with piperacillin-tazobactam were prospectively evaluated in 51 autologous peripheral blood stem cell transplantation (PBSCT) recipients. The results were compared with those obtained in 51 control patients receiving oral fluoroquinolones in a retrospective matched-pair control study. Overall, 76% of the study group and 98% of the control group developed at least one febrile episode during neutropenia (P=0.002). Time from neutropenia to the first febrile episode (FFE) was significantly longer in the study group than in the control group (P=0.04). Once a febrile episode appeared, the duration of fever was significantly longer in cases th…
The Respect of Recommendations Provided in an International Travelers' Medical Service: Far From the Cup to the Lips
2013
Equipe plutôt EA Pôle MERS CT3 EJ3; Background: It is not clearly known how frequently the recommendations given to travelers are followed, and what factors could encourage compliance with these recommended measures. Methods: Adults consulting at a Medical Department for International Travelers (International Travelers' Medical Services, ITMS) in October and November 2010 were asked to answer a questionnaire before their journey. They were also contacted for a post-travel telephone interview to determine whether they had followed the recommendations regarding vaccinations and malaria prevention, and the reasons for poor or noncompliance with these recommendations. Results A total of 353 tra…
Immune Tolerance Induction in Hemophilia A: A Review
2003
In this article, a comparative analysis of the data stemming from the studies conducted in the field of immune tolerance treatment (ITT) of hemophilia A was attempted. Comparisons are difficult because previous studies differ in many respects, including the dosage of factor (F) VIII, the number of FVIII administrations per day, the association with immunosuppressive drugs (prednisone, cyclophosphamide), and, most importantly, the definition of success in terms of the reacquisition of tolerance. However, a number of variables consistently influenced outcome: the inhibitor titer, either the maximum one or the one assayed before immune tolerance (IT) start and age. As to the FVIII dose, result…
Low-dose budesonide treatment for prevention of postoperative recurrence of Crohnʼs disease
1999
Summary and ConclusionAlthough the effect of budesonide was altogether positive in almost all variables studied in this train (e.g. endoscopic and histopathological score, time-to-failure, CDAI, patients' global judgement and rate of side effects), this increase in efficacy was small and the power f
Intravesical mitoxantrone in superficial bladder tumours (Ta-T1)
1993
Abstract 36 patients with histologically proven grade G1–G2, Ta-T1 transitional cell carcinoma of the bladder were introduced, after transurethral resection (TUR), into a study of intravesical chemoprophylaxis with mitoxantrone (20 mg diluted in 50 ml). After a mean follow-up of 23 months, 16 (50%) patients showed a superficial recurrence with a mean recurrence rate of 0.56 per year. In 19 patients with recurring tumours the mean recurrence rate decreased from 1.65 to 0.58 per year. 9 patients (25.7%) suffered from a chemical cystitis that in 2 cases (5.7%) required treatment interruption.
LOCAL MICROWAVE HYPERTHERMIA AND INTRAVESICAL CHEMOTHERAPY AS BLADDER SPARING TREATMENT FOR SELECT MULTIFOCAL AND UNRESECTABLE SUPERFICIAL BLADDER TU…
1998
Purpose: The role of a combined regimen of local hyperthermia and topical chemotherapy in patients with multifocal and recurrent superficial bladder tumors not curable by transurethral resection was evaluated in a neodjuvant organ sparing clinical study. Materials and Methods: A total of 19 patients with multifocal, superficial grades 1 to 3 bladder tumors that recurred after intravesical chemoprophylaxis or immunoprophylaxis underwent local combined administration of microwave induced hyperthermia and intravesical chemotherapy as a debulking approach. Due to extensive superficial involvement of the bladder walls complete transurethral resection of all tumors seemed technically unfeasible i…
