Body mass index and the clinicopathological characteristics of clinically localized renal masses-An international retrospective review.

OBJECTIVES: To investigate the potential association between body mass index (BMI) and clinicopathological features of clinically localized renal masses. MATERIALS AND METHODS: An international, multi-institutional retrospective review of patients who underwent surgery for clinically localized renal masses between 2000 and 2010 was undertaken after an institutional review board approval. Patients were divided into 4 absolute BMI groups based on the entire cohort׳s percentiles and 4 relative BMI groups based on their respective population (American or Italian). Renal mass pathological diagnosis, renal cell carcinoma (RCC) subtype, Fuhrman grade (low and high), and clinical stage were compared among groups using Fisher׳s exact test, Kruskal-Wallis test, and the Cochran-Armitage trend test. A multivariate logistic analysis was performed to evaluate independent association between tumor and patient characteristics with tumor pathology (Fuhrman grade). RESULTS: A total of 1,748 patients having a median BMI of 28 (interquartile range 25-32) were evaluated. Benign masses and RCC cases had similar proportion across BMI groups (P = 0.4). The most common RCC subtype was clear cell followed by papillary carcinoma, chromophobe, and other subtypes. Their distribution was comparable across BMI groups (P = 0.7). Similarly, clinical stage distribution was comparable with the overall cohort. The distribution of Fuhrman grade in RCC, however, demonstrated an increased proportions of low grade with increasing BMI (P<0.05). This trend was maintained in subgroups according to gender, stage and age (P<0.05 in all subgroup analysis). In a multivariable model that included potential confounders (i.e., age, sex, and tumor size) higher BMI groups had lower odds of presenting a high Fuhrman grade. CONCLUSION: In this study, higher BMI was associated with lower grade of RCC in clinically localized renal masses. This may, in part, explain better survival rates in patients with higher BMI and may correlate with a possible link between adipose tissue and RCC biology.

First case of bilateral, synchronous anaplastic variant of spermatocytic seminoma treated with radical orchifunicolectomy as single approach: case report and review of the literature.

Spermatocytic Seminoma (SS) is less common than the Classic variant, as its incidence ranges between 1.3% and 2.3% of all seminomas. Generally SS is diagnosed in men older than 50 years. The Anaplastic variant of Spermatocytic Seminoma is characterized by an earlier onset when compared to SS, but a benign behavior in spite of its histological patterns similar to Classic Seminoma. We reported the first case of bilateral, largest and synchronous Anaplastic Spermatocytic Seminoma, in a patient treated with radical orchifunicolectomy alone and with long-term follow-up. The currently available data show that Anaplastic SS reveals a clinically benign behavior, and no distant metastases have been reported so far. A close surveillance after surgery could be considered a valid option in the management of this rare testicular neoplasm.

Perioperative complications and mortality after radical cystectomy when using a standardized reporting methodology.

PURPOSE: To evaluate, by using a standardized reporting methodology, the perioperative complications and mortality in patients who underwent radical cystectomy. MATERIALS AND METHODS: We retrospectively reviewed all data of 404 consecutive patients who underwent radical cystectomy from 1995 to 2009 for nonmetastatic bladder cancer at the same academic center. Perioperative complications and perioperative mortality were defined as any adverse event or death from any cause within 90 days of surgery. All perioperative complications were reported according to the Martin criteria and were graded according to the Clavien system (grade 1-5). Univariate and multivariate analyses for the clinical and pathologic characteristics were used to evaluate predictors of complications. RESULTS: A total of 296 complications occurred in 209 (51.7%) patients. Among them, 139 (34.4% of the entire population) had only a '"minor"' (grade 1-2) complication, whereas 70 (17.3%) had a "major" (grade 3-5) complication. Eighteen (4.5%) patients died within 90 days after surgery. At univariate analysis, age ≥75 years (2P = .018), serum creatinine level ≥1.4 mg/dL (2P = .025), American Society of Anesthesiologists (ASA) score of 3 to 4 (2P < .001) were significant predictors of complications after 30 days from surgery; conversely, the ASA score was the only significant predictor of complications after 90 days. At multivariate analysis, only the ASA score was independently correlated with the development of complications at 30 and 90 days of follow-up (2P < .001). CONCLUSIONS: Radical cystectomy is one of the most complex procedures in urology, with a high rate of complications and mortality. The use of a standardized methodology is the only way to estimate the actual rate and the severity of complications.

[Accuracy of endorectal Magnetic Resonance Imaging (MRI) and Dynamic Contrast Enhanced-MRI (DCE-MRI) in the preoperative local staging of prostate cancer]. / Accuratezza della RMN 1,5 T con bobina endorettale e della RMN dinamica (DCE MRI) nella stadiazione preoperatoria dei pazienti affetti da carcinoma prostatico.

BACKGROUND: The proper management of newly diagnosed prostate cancer (PCa) requires the choice of the appropriate treatment plan. A crucial factor is the accurate evaluation of the tumor local extension. The Magnetic Resonance Imaging (MRI) plays an important role in the local staging of prostate cancer, although its use in clinical practice is widely debated. Therefore, the purpose of our study was to evaluate the diagnostic accuracy of T2-weighted MR imaging in association with DCE-MRI, performed using an endorectal coil, in preoperative local staging of patients with prostate cancer, by using the histopathologic findings as the reference standard. MATERIALS AND METHODS: From April 2010 to May 2011, 65 patients (mean age, 65 years; range, 51-77 years) with clinical localized PCa, underwent radical prostatectomy at our institution, performed by 2 experienced surgeons. All patients were prospectively evaluated with eMRI in association with DCE-MRI prior to radical prostatectomy. In all patients MRI was performed at least 6 weeks after biopsy and within 2 weeks before Radical Prostatectomy (RP). Histologic analysis was our diagnostic "gold standard". To ensure that the histopathological findings matched with MR images, the assessment of radiological images and the RP specimens were performed dividing the prostate in 14 regions. RESULTS: First, we performed a "per-patient" analysis, considering the entire prostate as a single region. Then, we performed a "per-emigland" analysis, finally a "per-region" analysis. The sensitivity, specificity, PPV, NPV and AUC in predicting ECE in the analysis "per-emigland" were respectively 66.7, 95.7, 66.7, 95.7, 0.824. The evaluation of SVI reported similar results: 62.5, 97.5, 62.5, 97.5, 0.797. DCE-MRI did not improve the diagnostic accuracy of T1-T2-weighted MR images in the evaluation of ECE or SVI. CONCLUSIONS: T1-, T2-weighted MRI adds important information regarding the preoperative local staging of PCa. DCE-MRI does not improve the diagnostic accuracy of MRI in the local staging of PCa.

What is the impact on sexual function of laparoscopic treatment and subsequent combined oral contraceptive therapy in women with deep infiltrating endometriosis?

INTRODUCTION: Deep infiltrating endometriosis (DIE) is a form of endometriosis in which the lesion penetrates for more than 5 mm under the peritoneal surface. It is a chronic disease which can impair women's sexual function. There is a growing body of evidence supporting combined surgical/medical treatment in the management of DIE. AIMS: The aims of this article are to evaluate the impact of the laparoscopic full excision of endometriosis and postoperative combined oral contraceptives (COC) administration on sexual function in patients with DIE and to compare sexual function outcomes of women submitted to intestinal resection and nodule excision. METHODS: It is a prospective cohort study in a tertiary care university hospital on 106 sexually active women, with histologically confirmed DIE, managed by laparoscopy and subsequent COC therapy for 6 months. Patients filled preoperatively and 6-month postoperatively a quality of sexual life questionnaire, the Sexual Health Outcomes in Women Questionnaire (SHOW-Q) and they ranked their symptom intensity using a 10-point visual analogue scale (VAS). MAIN OUTCOME MEASURES: Sexual function was measured through the SHOW-Q scores and pain symptoms through VAS scores. Intraoperative details, type of intervention and perioperative complications were noted. RESULTS: Six months after surgery and postoperative COC treatment, a significant improvement was observed in the SHOW-Q domains of pelvic problem interference, sexual satisfaction and desire (P<0.05). Laparoscopic management of DIE did not change significantly the orgasm area of the sexual functioning (P=0.7). No significant difference was found in SHOW-Q scores between patients submitted to intestinal resection and patients submitted to intestinal nodule excision (P>0.05). CONCLUSIONS: Sexual desire, satisfaction with sex and pelvic problem interference with intercourse are significantly improved after 6 months from laparoscopic excision of DIE combined with postoperative COC therapy. No difference in sexual outcomes was detected between patients submitted to intestinal resection and nodule excision.
