protoves m1® syrup in controlling adverse event during hivec® instillations

Conditions: Bladder Cancer; LUTS; Pain

Summary: 100 patients with bladder cancer whose underwent hyperthermic intravesical chemotherapy (hivec®) will be randomized in two groups (group a: protoves m1 syrup, group b: no treatment). the aim of this study will be to analyse the role of two alkaloid, protopine and nuciferine (protoves-m1 ®) in the prevention and the treatment of the low and mild grade adverse events related to the use of hivec® instillations.

100 patients with bladder cancer whose underwent hyperthermic intravesical chemotherapy (hivec®) will be randomized in two groups (group a: protoves m1 syrup, group b: no treatment). the aim of this study will be to analyse the role of two alkaloid, protopine and nuciferine (protoves-m1 ®) in the prevention and the treatment of the low and mild grade adverse events related to the use of hivec® instillations. at the baseline data on demographic and anthropometric features (age, weight, height, bmi), lifestyle characteristics (smoke, alcohol), any comorbidities (hypertension, diabetes mellitus, etc.) will be collected. all patients will be undergone to a clinical evaluation (comprised general, genital and urologic examination). before starting the treatment, the following measurements will be collected: prostate volume by transrectal ultrasound, psa, uroflowmetry (qmax, volume voided, post-void residual), ipss (international prostatic symptoms score) questionnaire, overactive bladder questionnaire-short form (oabq-sf) 6 and 13, patient perception of intensity of urgency scale (ppius), and visual analogue scale (vas). psa and ipss will be investigated only in male pts. in addition, the patient impression of improvement will be assessed. improvement will be evaluated with the patient global impression of improvement questionnaire (pgi-i), a validated tool to estimate the improvement or the deterioration associated to the treatment. the primary endpoint was the evaluation of the efficacy of the therapy with protoves-m1 in controlling of the irritative symptoms, including nocturia, urinary frequency, bladder pain, urgency and urge incontinence related to the chemo-hyperthermia treatment. the secondary endpoint evaluated was the influences of the treatment on the uroflowmetric parameters. after 1 and 6 weeks of therapy all patients will be undergone to a clinical and instrumental evaluation : uroflow-qmax (ml/s), uroflow-volume voided (ml),uroflow-rpm (ml), ipss total, oab-q sf 6, oab-q sf 13, ppius, pgi-i, vas scale will be collected.
