[Imaging diagnosis of non-lymph node metastasis of bladder carcinoma].

Assessment of presence of metastatic disease (m.d.) in bladder cancer (b.c.) can represent a main problem as influencing the appropriate therapeutic policy (mostly the indication to radical surgery). Evaluation of the real cost-effectiveness ratio of radiographic and radionuclide diagnostic work-up induced us to retrospectively review historical data about our b.c. patients (pts). From March 1988 to June 1991, 76 not consecutive pts with histologically proven bladder cancer were included in this study. 5 Pts were staged as T1, 25 as T2, 18 as T3a, 23 as T3b, 5 as T4. 2 Pts were graded as G1, 27 as G2, 44 as G3, 3 as Gx. Age varied from 39 to 89 years (average: 62.3). 79 Pts underwent the "basic work-up" (including chest plain film, bone and liver scans) and at least one follow-up control. 266 chest plain films, 22 chest x-ray tomograms, 2 chest CT scans, 27 bone x-ray tomograms, 231 bone scans, 240 liver scans, 17 liver ultrasonographies were totally realized. All pts underwent at least an abdomen-pelvic CT, but related results are not considered in the study. Fine needle aspiration cytologic biopsies were realized in selected cases; also these results are not selectively reported here. Together with cytologic positive results, only progression of m.d. was considered as its definite presence. Conventional x-ray examination (plain film integrated by x-ray tomograms of "suspicious" findings) resulted sufficiently complete and accurate to reveal chest m.d. Concerning skeletal diagnostic survey, only 6 pts (26%) out of 23 pts with "positive" bone scans really resulted affected by m.d.(ABSTRACT TRUNCATED AT 250 WORDS

Presence and severity of lower urinary tract symptoms are inversely correlated with the risk of prostate cancer on prostate biopsy

BACKGROUND: The assessment of lower urinary tract symptoms (LUTS) is common part of urological investigation. Furthermore, patients bother of prostate cancer (PCA) when they are affected of LUTS. This study was aimed to determine whether the presence and severity of LUTS, as assessed by the International Prostate Symptoms Score (IPSS), could help to identify patients at higher risk of prostate cancer (PCA) on prostate biopsy (PBx). In this effort, an initial PCA predictive model was calculated and IPSS was subsequently added. The diagnostic accuracy of both models was compared. METHODS: The analysis of prospectively collected data of patients scheduled for PBx at four academic hospitals between January 2012 and June 2015 was performed. Univariate and multivariate analysis assessed the correlation between the IPSS and the risk of being diagnosed with PCA; Receiver operator characteristic curve (ROC) analysis evaluated the predictive models including or not the IPSS. RESULTS: Of the 1366 enrolled patients, 706 (52%) were diagnosed with PCA. Patients with PCA had a significantly lower IPSS (10.6±7.4 vs. 12.7±8.1) than those with benign diagnosis. Multivariate logistic regression analysis showed that age, prostate-specific antigen (PSA), prostate volume and IPSS were the most significant predictors of PBx outcome, (OR 1.61, P=0.001; OR 1.20, P=0.001; OR 0.97, P=0.001; OR 0.74, P=0.004; respectively). ROC curve analysis showed that the addition of IPSS to the predictive model based on age, PSA, DRE and prostate volume significantly improved the model diagnostic accuracy (AUC: 0.776 vs. 0.652; P=0.001). CONCLUSIONS: Presence and severity of LUTS are inversely correlated with the risk of being diagnosed with PCA at PBx. Incorporating the IPSS into predictive models may reduce the risk of unnecessary PBxs

A larger detrusor wall thickness increases the risk of non muscle invasive bladder cancer recurrence and progression. Result from a multicenter observational study

BACKGROUND: Recent experimental study showed a higher incidence of bladder cancer in presence of bladder detrusor muscle thickening. The aim of this study is to assess whether a higher detrusor muscle thickness (DWT) may be a risk factor of recurrence of non-muscle invasive urothelial bladder cancer (NMIBC). METHODS: Men with histologically-confirmed diagnosis of NMIBC were prospectively enrolled in 4 centers between December 2015 and April 2017. DWT was measured by ultrasound and DWT>2.5 mm was used as threshold for detrusor muscle thickening. Patients underwent to adjuvant local treatment in according to their progression and recurrence risk computed by European Organization Research and Treatment of Cancer (EORTC) Score for NMIBC. Every three months cystoscopy and urinary cytology were used to detect disease recurrence and progression. The main clinic-pathological variables were compared between patients with DWT=2.5 mm and DWT>2.5 mm. RESULTS: One hundred patients (49.8%) with DWT >2.5 mm were significantly older, had larger and more tumors and experienced more prior NMIBC than 101 (50.2%) patients with a DWT=2.5 mm. Recurrence and progression disease occurred more often and briefly in patients with a detrusor muscle thickening. At univariate analysis, DWT>2.5 was a predictive risk factors of cancer recurrence and progression, respectively: OR 4.9 (95% CI: 2.5-9.5) P=0.001 and OR 2.21 (95% CI: 1.71-4.73), P=0.001. Enclosing DWT in EORTC risk calculator significantly increased by 3% and 1% recurrence and progression risk assessment, respectively. CONCLUSIONS: Detrusor muscle thickening may have a role in NMIBC course with a higher recurrence rate, however further confirmatory and elucidating studies are required
