Intravesical bleomycin in bladder tumour prophylaxis.
1986
The authors have evaluated the efficacy, tolerability and systemic absorption of bleomycin administered by intravesical route in the prophylaxis of recurrences of superficial vesical tumours after endoscopic resection (TUR). Thirty mg of bleomycin dissolved in 30 ml of saline solution were instilled in the bladder once a week for the first month and then once a month for 12 months. The instilled fluid was held in the bladder for 1 hour. The systemic absorption of the drug was evaluated by a microbiological assay of bleomycin in plasma and in the perfusion liquid recovered from the bladder. Fifteen patients were treated; most had a long history of multiple recurrent tumours despite previous …
Recurrence, progression and cancer-specific mortality according to stage at re-TUR in T1G3 bladder cancer patients treated with BCG: not as bad as pr…
2018
PURPOSE: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis to adequately stage and treat the patient. Persistent disease after TUR is not uncommon and is why re-TUR is recommended in T1G3 patients. When there is T1 tumor in the re-TUR specimen, very high risks of progression (82%) have been reported. We analyze the risks of recurrence, progression to muscle-invasive disease and cancer-specific mortality (CSM) according to tumor stage at re-TUR in T1G3 patients treated with BCG. METHODS: In our retrospective cohort of 2451 T1G3 patients, 934 patients (38.1%) underwent re-TUR. 667 patients had residual disease (7…
Correlation between clinical response and urinary interleukin levels using different doses and intravesical administration schedules of interferon-al…
1993
A total of 62 patients at high risk for recurrence of superficial bladder cancer were selected for a study designed to compare the prophylactic efficacy of different doses and schedules of sequential intravesical instillations of epirubicin and interferon-alpha-2b and to evaluate which sequence could enhance the release of cytokines in the urine. Our investigations showed a significant increase in urinary concentrations of interleukins in patients who received the sequential intravesical administration of epirubicin and interferon-alpha-2b. Higher urinary concentrations of interleukins and a lower recurrence rate were detected in patients who received interferon-alpha-2b 24 h after epirubic…
A pilot study comparing different dose levels and administration schedules of interferon-α2b combined with epirubicin for prevention of recurrence in…
1992
A pilot study in 62 patients has been carried out to evaluate the combination of epirubicin and interferon (IFN)-alpha 2b using different doses and schedules of intravesical administration in the prevention of recurrence of bladder cancer. Preliminary results show greater prophylactic efficacy not only when higher doses of epirubicin and IFN-alpha 2b are used but also when a larger interval between instillation of the compounds was used.
Combination of intravesical chemotherapy and hyperthermia for the treatment of superficial bladder cancer: preliminary clinical experience
2003
The prevalence of superficial transitional cell carcinoma of the bladder (STCCB) is still increasing in spite of improved adjuvant chemotherapic and/or immunoprophylaxis approaches. Thus, there is certainly an urgent need to improve our ability to control this disease. Local hyperthermia has a therapeutical potential for the treatment of many solid tumors, especially when used in combination with other treatments, such as radiation and chemotherapy. In particular, a synergistic or, at least, supra-additive antitumor cell killing effect was documented when local hyperthermia was administered in combination with selected cytostatic drugs. Recently, advances in miniaturized technology have all…
[Endovesical treatment as an alternative to BCG for intermediate or high-risk NMI bladder cancer].
2012
A shortage of BCG is foreseen till the end of 2013. Which will be the management of intermediate and high-risk NMI-BC if BCG will not be available? In patients harboring high-risk NMI tumors, particularly T1G3 and Tis, the first therapeutic choice is radical cystectomy. Device-assisted therapies, although showing promising results, should be considered only for selected patients. In intermediate risk patients, intravesical chemotherapy remains a legitimate option even if BCG is available. Thus, in a period of BCG shortage, intravesical chemotherapy should be offered, preferably preceded by early instillation, according to the EAU guidelines.
Intravesical gemcitabine in superficial bladder tumors. Results of a phase I-II study
2004
the good tolerability of intravesical gemcitabine have been recently published. The evaluation of the activity on a papillary marker lesion is the best tool to measure the efficacy of a drug by intravesical route against superficial transitional cell carcinoma of the bladder (TCCB). The scientific background and the ethical acceptability of this approach have been validated by the European Organization for Research and Treatment of Cancer Urological Group. The aim of the present study was to evaluate the ablative efficacy of weekly intravesical instillations of gemcitabine against a histologically proven papillary marker lesion. MATERIAL & METHODS: Twenty-seven patients, affected by recurre…
Is the efficacy of intravescical chemotherapy influenced by cigarette smoking? Data obtained in intermediate risk non muscle invasive bladder carcino…
2011
Aim of the study To study recurrence-free rate (RFR) and recurrence-free survival (RFS) according to the smoking status in patients affected by non-muscle invasive carcinoma of the bladder (NMI-BC) treated by intravesical chemotherapy. Materials and methods Smoking status was recorded at study entry. Intravesical epirubicin was administered within 6 hours from TUR at the dose of 80 mg diluted in 50 ml of saline solution. Further adjuvant treatment in low-risk and high-risk patients was given according to physicians’ choice. The remaining patients, at intermediate risk for recurrence, were randomized between two different schemes of intravesical chemotherapy: 5 more weekly instillations (tot…
CHOICE OF ADJUVANT INTRAVESICAL THERAPY IN RECURRING INTERMEDIATE-RISK NMI-BC
2011
Objective: The therapeutic strategy for patients affected by intermediate risk non-muscle invasive bladder cancer (NMIBC) recurring after intravesical therapy is not definitively established. Only few studies have been published on secondline intravesical therapy. BCG is advocated when intravesical chemotherapy fails and is often repeated. On the other hand, some patients that suffer recurrence repeat intravesical chemotherapy. A retrospective analysis of 179 intermediaterisk patients submitted to second-line intravesical therapy is reported. Patients and Methods: The clinical files of patients affected by intermediate risk NMI-BC and submitted to second-line adjuvant intravesical therapy w…
