Is there still a role for computed tomography and bone scintigraphy in prostate cancer staging? An analysis from the EUREKA-1 database.

PURPOSE: According to the current guidelines, computed tomography (CT) and bone scintigraphy (BS) are optional in intermediate-risk and recommended in high-risk prostate cancer (PCa). We wonder whether it is time for these examinations to be dismissed, evaluating their staging accuracy in a large cohort of radical prostatectomy (RP) patients. METHODS: To evaluate the ability of CT to predict lymph node involvement (LNI), we included 1091 patients treated with RP and pelvic lymph node dissection, previously staged with abdomino-pelvic CT. As for bone metastases, we included 1145 PCa patients deemed fit for surgery, previously staged with Tc-99m methylene diphosphonate planar BS. RESULTS: CT scan showed a sensitivity and specificity in predicting LNI of 8.8 and 98 %; subgroup analysis disclosed a significant association only for the high-risk subgroup of 334 patients (P 0.009) with a sensitivity of 11.8 % and positive predictive value (PPV) of 44.4 %. However, logistic multivariate regression analysis including preoperative risk factors excluded any additional predictive ability of CT even in the high-risk group (P 0.40). These data are confirmed by ROC curve analysis, showing a low AUC of 54 % for CT, compared with 69 % for Partin tables and 80 % for Briganti nomogram. BS showed some positivity in 74 cases, only four of whom progressed, while 49 patients with negative BS progressed during their follow-up, six of them immediately after surgery. CONCLUSIONS: According to our opinion, the role of CT and BS should be restricted to selected high-risk patients, while clinical predictive nomograms should be adopted for the surgical planning.

Sexual function in women undergoing hemodialytic treatment assessed using the female sexual function index (FSFI) and the somatic inkblot series (SIS) test.

AIMS: Female sexuality in end-stage renal disease has so far only been explored using non-validated tools. The aim of this study was to compare sexual function among hemodialyzed (HD) patients and healthy controls using validated questionnaires. MATERIAL: Two internationally validated tests have been administrated: the female sexual function index (FSFI) questionnaire and a set of tables from the somatic inkblot series (SIS) test which focus specifically on the area of sexuality. METHODS: 25 consecutive HD patients were assessed for sexual function using the FSFI. Nine SIS inkblots concerning sexuality were also administered to obtain more detailed information about the psychological component of sexuality. An equal number of control healthy volunteers perfectly matched for age, marital status and educational level underwent the same evaluations, and the results of the two groups were compared. RESULTS: HD patients had significantly lower scores than the controls for all FSFI domains except sexual desire even when stratified by age and marital status. All sexually related thematic areas of the SIS except body perception were significantly affected in the HD group compared to the control group. CONCLUSIONS: Chronic renal failure requiring HD treatment adversely affects female sexual function. The psychological impact on patients is significant when compared to an age-matched control group. Both the FSFI questionnaire and the SIS test may be considered useful tools for an integrated medical and psychological screening of FSD.
