ABSTRACTS <strong>XIV</strong> <strong>Congresso</strong> <strong>Nazionale</strong> <strong>Società</strong> <strong>Italiana</strong> <strong>di</strong> Urologia OncologicaIntroduzione: Descriviamo l’approccio chirurgico conservativo,organ sparing, in un caso <strong>di</strong> neoplasia testicolare bilateralemetacrona.Materiali e Meto<strong>di</strong>: In un paziente <strong>di</strong> anni 27, già sottoposto adorchiectomia destra <strong>per</strong> carcinoma embrionario (sta<strong>di</strong>o clinicoII B), chemioterapia a<strong>di</strong>uvante e linfadenectomia retro<strong>per</strong>itonealebilaterale, veniva riscontrata, a <strong>di</strong>stanza <strong>di</strong> 2 anni, unaneoformazione del polo su<strong>per</strong>iore del <strong>di</strong><strong>di</strong>mo su<strong>per</strong>siste <strong>di</strong>circa 2 cm con contestuale incremento dell’AFP (alfa feto proteina).Su richiesta del paziente, dopo averne comprovato ilnormale assetto ormonale, veniva eseguita una orchiectomiaparziale sinistra. La tecnica prevede la enucleo-resezione deltumore, previo clampaggio del funicolo, e multiple biopsie del“letto <strong>di</strong> resezione” <strong>per</strong> esame istologico estemporaneo.Biopsie random del parenchima <strong>di</strong>stale devono essere eseguite<strong>per</strong> escludere la contestuale presenza <strong>di</strong> T.I.N. L’esame istologicodefinitivo riba<strong>di</strong>va la <strong>di</strong>agnosi <strong>di</strong> neoplasia maligna acellule germinali a componente mista teratomatosa e del tipocarcinoma embrionario.Risultati: A <strong>di</strong>stanza <strong>di</strong> 12 mesi dall’intervento non è statariscontrata reci<strong>di</strong>va neoplastica, con normalizzazione dell’AFP;il paziente non riferisce <strong>di</strong>sturbi della libido e della potenza epresenta un normale assetto ormonale.Discussione: La chirurgia organ-sparing dei tumori del testicoloè in<strong>di</strong>cata <strong>per</strong> tumori bilaterali, sincroni o metacroni, e <strong>per</strong>quelli insorti in testicolo singolo, purché organo-confinati e <strong>di</strong><strong>di</strong>ametro inferiore a 2,5 cm (1). Tale approccio si propone <strong>di</strong>preservare la fertilità e la qualità <strong>di</strong> vita dei pazienti, altrimentiinficiata dalla deplezione androgenica e dallo stress psicologicodella castrazione. I rischi <strong>di</strong> malattia multifocale e <strong>di</strong> reci<strong>di</strong>valocale impongono una attenta valutazione intrao<strong>per</strong>atoriadel parenchima residuo ed uno stretto follow-up.Bibliografia:1.

Metastatic RCC(MRCC) has a poor prognosis with a me<strong>di</strong>an overall survival ofabout one year (1). There is no standard treatment for MRCC.Chemotherapy is generally ineffective and immunotherapybasedregimens are considered of a modest efficacy.Nevertheless, cytokines are the only drugs that have beenshown to induce tumour regression in some patients. á-IFN andIL-2 have been found to induce objective response rates from15% to 20% as monotherapy and are now being investigated ascomponents of combined regimens (2, 3). In our Institution weanalysed a panel of pre-treatment bio-humoral and clinical factorsto verify their pre<strong>di</strong>ctive impact on survival and clinicalresponse of patients affected by MRCC treated with three <strong>di</strong>fferentregimens inclu<strong>di</strong>ng low dose subcutaneous IL-2.Methods: A total of 110 patients treated at the OncologyInstitute of Bari, Italy from 1992 until 2002, were analysed.Three <strong>di</strong>fferent therapeutic regimens IL-2-based were used.Pre-treatment total lymphocytes, lactate dehydrogenase(LDH), erytrose<strong>di</strong>mentation rate (ESR), albumin, C-reactiveprotein (CRP), and fibrinogen were analysed. Moreover, clinicalparameters (<strong>per</strong>formance status, age, sex, prior nephrectomy,number of metastatic sites, <strong>di</strong>sease site, and <strong>di</strong>sease freeinterval from nephrectomy to metastatic <strong>di</strong>sease (DFI)) wereconsidered.Results: The me<strong>di</strong>an survival of all patients was 12 months (33months for PR+CR, 14 months for SD, 7 months for PRO).Overall response was 24% PR+CR, 37% SD and 39% PRO. Inunivariate analysis, a good ECOG PS (P=0.0000), prior nephrectomy(P=0.0001), DFI longer than 12 months (P=0.0003),bone <strong>di</strong>sease site (P=0.0013), low number of metastatic site(P=0.0449), normal albumin levels (P=0.0001), low/normalfibrinogen levels (P=0.0140) and low/normal LDH levels(P=0.0430) were related to a better survival. In a final multivariateanalysis only CRP (P=0.002; Hazard Ratio=4.12; IC 95%1.68 – 10.15) and DFI (P=0.0497; Hazard Ratio=0.44; IC 95%0.20 – 0.99) were found to have an independent role on survival.When we correlated clinical and bio-humoral factorsonly CRP was found correlated with DFI (P=0.021) and priornephrectomy (P=0.041). When we carried out a multivariateanalysis considering CRP as continuous variable, we confirme<strong>di</strong>ts strong impact on survival (P=0.0003; HR = 1.1 and IC 95%HR 1.04-1.15).Conclusions: Our data confirm that some clinical and biohumoralfactors may be strongly related to survival in MRCCpatients. The interesting new aspect emerging from this studyis the prognostic value of the basal levels of CRP and fibrinogen,which seem to be <strong>di</strong>scriminating factors between a goodor bad prognosis. Particularly, in the multivariate analysis CRPresulted the most important independent prognostic factorableof survival.References:1. Bleumer I, et al. Immonotherapy for renal cell carcinoma.
