ABSTRACTS <strong>XIV</strong> <strong>Congresso</strong> <strong>Nazionale</strong> <strong>Società</strong> <strong>Italiana</strong> <strong>di</strong> Urologia Oncologica18 pz e nussun tipo <strong>di</strong> ischemia in 64 pz.. Il tempo me<strong>di</strong>o <strong>di</strong>ischemia è stato <strong>di</strong> 15 minuti (min. 3-max. 58).Risultati: Su 225 pazienti trattati 15 hanno presentato lesioni acarattere benigno (angiomiolipomi, oncocitomi, cisti). 6 pazientisu 210 con carcinoma renale sono deceduti, <strong>di</strong> questi 5 <strong>per</strong>progressione della malattia ed 1 <strong>per</strong> cause <strong>di</strong>verse. 2 pazientisono stati successivamente sottoposti a nefrectomia <strong>per</strong> reci<strong>di</strong>valocale.Conclusioni: La nostra casistica si presenta come una delle piùampie a livello internazionale <strong>per</strong> singola Unità O<strong>per</strong>ativa <strong>di</strong>Urologia. L’analisi matematica e statistica dei dati raccolti evidenziauna significativa correlazione tra <strong>di</strong>ametro TC e <strong>di</strong>ametropatologico atteso. All’aumento delle <strong>di</strong>mensioni della neoplasia(> 4 cm) sembra corrispondere un rischio maggiore <strong>di</strong> infiltrazionedel grasso <strong>per</strong>irenale, anche se non è stata raggiunta unapiena significatività statistica. I confortanti risultati in termini <strong>di</strong>sopravvivenza non sembrano porre limiti a questa tecnica chirurgica,le <strong>di</strong>mensioni (> <strong>di</strong> 4 cm) e la localizzazione non costituisconopiù una controin<strong>di</strong>cazione assoluta al trattamento conservativo.Bibliografia:1.

Marta, S. Venera <strong>di</strong> Acireale, ItalyBackground: The androgen blockade remains the critical therapeuticoption for the treatment of advanced stage prostate cancer.However, after an initial response, most of the prostatecancers become androgen-independent and progress further,with a fatal outcome. The options for the treatment of hormone-refractory<strong>di</strong>sease include supportive-care or chemotherapy.Novel treatment regimens for androgen-independentprostate cancer are necessary because currently availableapproaches have not been shown to improve survival.Methods: From December 2002 to March 2004, 40 patients withprostate carcinoma were treated in our department of Me<strong>di</strong>calOncology. The mean age of patients was 68 years (range 51-80),the mean Gleason Score was 7 (4+3) and the basal PSA had amean value of 180 ng/mL (range 0-3495). All patients had a good<strong>per</strong>formance status (ECOG 0-1). The previous treatments weresurgery alone (2 pts), ra<strong>di</strong>otherapy alone (2 pts), surgery and hormonotherapy(4 pts), ra<strong>di</strong>o- and hormonotherapy (5 pts), hormonaltherapy alone (11 pts) and all these three therapies (9 pts);of these 33 pretreated patients, 31 had a progressive <strong>di</strong>sease afterhormonal therapy and antiandrogen withdrawl. 38 patients had ametastatic <strong>di</strong>sease: the most frequent site of relapse was bone (34pts); only 1 patient was free of <strong>di</strong>sease and in another one the progressionwas documented only by biochemical failure.Treatment Plan: 28 patients were treated by chemotherapy, withmithoxantrone and prednisone (22 pts) or weekly docetaxel (6patients); of all them, 13 underwent a methabolic ra<strong>di</strong>otherapybefore or after chemioterapy.Results: The most common Grade 2 toxicities were neutropenia, fatigue,nausea and emesis in 18% 40%, 25% and 12% of patientsrespectively. Grade 3-4 toxicities were haematological (anemia andneutropenia in 30% of pts). Of all 28 chemotherapy-treatedpatients, 6 had a biochemical response, 2 had an objective partialresponse and 3 had an objective stabilization of the <strong>di</strong>sease; 10 pts(30%) had an improvement of the <strong>di</strong>sease-related symptoms.Conclusions: Chemotherapy in metastatic hormone refractoryprostate cancer is feasible. It’s evident the palliative role of chemotherapyin pts with symptomatic hormone-refractory <strong>di</strong>seasebut in advanced stages it doesn’t alter the natural history ofthe <strong>di</strong>sease. Chemotherapy could have a potential role in theearlier stages of prostate cancer.References:1.
