A novel combination of triple metachronous malignancies of the kidney, oropharynx and prostate. A case report

Synchronous or metachronous malignancies are a rare event, with an incidence rate that increases with age. The present study reports the case of a 70-year-old Caucasian male who was referred to the outpatient office of the Urology Unit, Sapienza University of Rome (Latina, Italy) due to lower urinary tract symptoms. An abdominal ultrasound investigation was performed that demonstrated the presence of a right renal mass. The patient underwent right radical nephrectomy, which resulted in the definitive diagnosis of clear cell type renal cell carcinoma. The patient was eventually diagnosed with triple primary metachronous cancer consisting of renal clear cell carcinoma, prostate adenocarcinoma and squamous cell carcinoma of the oropharynx (palatine tonsil). To the best of our knowledge, this combination of primary neoplasms has not previously been documented

Combined laparoscopic pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi. Long-term follow-up results from a case series

Purpose: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes. Methods: From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7.2 cm; range, 6.2–9.0 cm) underwent a combined laparoscopic and endoscopic approach. The technique comprised laparoscopic pyelolithotomy and holmium-YAG laser stone fragmentation with the use of a flexible cystoscope introduced through a 12 mm trocar. Results: The average operative time was 140 min (range, 90–190 min). The mean estimated hemoglobin loss was 0.6 mmol/l (range 0.5–0.7 mmol/l). None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2–6 days). A computed tomography urogram control at 6 months of follow up did not show any stone recurrence. Conclusions: Laparoscopic pyelolithotomy combined with endoscopic pyelolithotripsy could be a therapeutic option in cases where mini-invasive procedures, that is, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotomy (PCNL) have failed. This technique has a high stone-clearance rate (75–100%) comparable with open surgery and PCNL. However, it could be technically demanding and should be performed by skilled laparoscopy surgeons

Can daily intake of aspirin and/or statins influence the behavior of non-muscle invasive bladder cancer? A retrospective study on a cohort of patients undergoing transurethral bladder resection

Background: This study aimed to evaluate the behavior of non-muscle-invasive bladder cancer (NMIBC) in patients submitted to transurethral bladder resection (TURB) comparing subjects in chronic therapy with aspirin, statins, or both drugs to untreated ones. Methods: This retrospective study was conducted on 574 patients diagnosed with NMIBC who underwent TURB between March 2008 and April 2013. The study population was divided into two main groups: treated (aspirin and/or statins) and untreated. The treated group was further divided into three therapeutic subgroups: Group A (100 mg of aspirin, daily for at least two years); Group B (20 mg or more of statins, daily for at least two years); and Group C (100 mg of aspirin and 20 mg of statins together). The mean follow-up of patients was 45.06 months. Results: No significant differences were observed among the different groups at baseline. On multivariate analysis, statin treatment, smokers and high stage disease (T1) achieved the level of independent risk factor for the occurrence of a recurrence. When patients were stratified according to the different treatment; patients treated with statins (Group B) presented an higher rate of failure (56/91 patients; 61.5%) when compared to Group A (42/98 patients; 42.9%), Group C (56/98; 57.1%) and (133/287 patients; 46.3%). This difference corresponds to a significant difference in recurrence failure free survival (p = 0.01). Conclusions: Our results suggest that long-term treatment with aspirin in patients with NMIBC might play a role on reducing the risk of tumor recurrence. In contrast, in our investigation data from statins and combination treatment groups showed increased recurrence rates. A long-term randomized prospective study could definitively assess the possible role of this widely used drugs in NMIBC

Oncogenic microRNAs characterization in clear cell renal cell carcinoma

A key challenge for the improvement of clear cell renal cell carcinoma (ccRCC) management could derive from a deeper characterization of the biology of these neoplasms that could greatly improve the diagnosis, prognosis and treatment choice. The aim of this study was to identify specific miRNAs that are deregulated in tumor vs. normal kidney tissues and that could impact on the biology of ccRCC. To this end we selected four miRNAs (miR-21-5p, miR-210-3p, miR-185-5p and miR-221-3p) and their expression has been evaluated in a retrospective cohort of formalin-fixed paraffin-embedded (FFPE) tissues from 20 ccRCC patients who underwent surgical nephrectomy resection. miR-21-5p and miR-210-3p resulted the most significantly up-regulated miRNAs in this patient cohort, highlighting these onco-miRNAs as possible relevant players involved in ccRCC tumorigenesis. Thus, this study reports the identification of specific oncogenic miRNAs that are altered in ccRCC tissues and suggests that they might be useful biomarkers in ccRCC management

Secreted miR-210-3p as non-invasive biomarker in clear cell renal cell carcinoma

The most common subtype of renal cell carcinoma (RCC) is clear cell RCC (ccRCC). It accounts for 70-80% of all renal malignancies representing the third most common urological cancer after prostate and bladder cancer. The identification of non-invasive biomarkers for the diagnosis and responsiveness to therapy of ccRCC may represent a relevant step-forward in ccRCC management. The aim of this study is to evaluate whether specific miRNAs deregulated in ccRCC tissues present altered levels also in urine specimens. To this end we first assessed that miR-21-5p, miR-210-3p and miR-221-3p resulted upregulated in ccRCC fresh frozen tissues compared to matched normal counterparts. Next, we evidenced that miR-210-3p resulted significantly upregulated in 38 urine specimens collected from two independent cohorts of ccRCC patients at the time of surgery compared to healthy donors samples. Of note, miR- 210-3p levels resulted significantly reduced in follow-up samples. These results point to miR-210-3p as a potential non-invasive biomarker useful not only for diagnosis but also for the assessment of complete resection or response to treatment in ccRCC management

Robot-assisted retroperitoneal lymphadenectomy in patient with type I papillary renal cancer recurrence after 5 years of follow-up

Papillary renal cell carcinoma (PRCC) is a rare cancer and is the second most frequent histologic type among all renal cell carcinoma, accounting for up to 15%. A 72-year-old man underwent a right radical nephrectomy 7 years ago with final histopathology diagnosis of type 1 PRCC with negative surgical margins. Five years after surgery, computed tomography scan imaging showed the presence of multiple masses suspicious for node recurrences disease localized in the renal lodge, in the inter-aorto-caval space, at the iliac vessels bifurcation and right common iliac vessels. Patient underwent a robotic retroperitoneal lymphadenectomy. The histopathological examination confirmed the recurrence of type I papillary renal cancer in all the specimens. No further recurrences have been observed at 24-month follow-up after surgery. This report is the first describing a robot-assisted minimally invasive surgical excision for type I papillary renal cancer nodal and renal fossa recurrences

T1 Bladder Cancer: Comparison of the Prognostic Impact of Two Substaging Systems on Disease Recurrence and Progression and Suggestion of a Novel Nomogram

Background: The T1 substaging of bladder cancer (BCa) potentially impacts disease progression. The objective of the study was to compare the prognostic accuracy of two substaging systems on the recurrence and progression of primary pathologic T1 (pT1) BCa and to test a nomogram based on pT1 substaging for predicting recurrence-free survival (RFS) and progression-free survival (PFS).Methods: The medical records of 204 patients affected by pT1 BCa were retrospectively reviewed. Substaging was defined according to the depth of lamina propria invasion in T1(a-c) and the extension of the lamina propria invasion to T1-microinvasive (T1(m)) or T1-extensive (T1(e)). Uni- and multivariable Cox regression models evaluated the independent variables correlated with recurrence and progression. The predictive accuracies of the two substaging systems were compared by Harrell's C index. Multivariate Cox regression models for the RFS and PFS were also depicted by a nomogram.Results: The 5-year RFS was 47.5% with a significant difference between T1(c) and T1(a) (p = 0.02) and between T1(e) and T1(m) (p < 0.001). The 5-year PFS was 75.9% with a significant difference between T1(c) and T1(a) (p = 0.011) and between T1(e) and T1(m) (p < 0.001). Model T1(m-e) showed a higher predictive power than T1(a-c) for predicting RFS and PFS. In the univariate and multivariate model subcategory T1e, the diameter, location, and number of tumors were confirmed as factors influencing recurrence and progression after adjusting for the other variables. The nomogram incorporating the T1(m-e) model showed a satisfactory agreement between model predictions at 5 years and actual observations.Conclusions: Substaging is significantly associated with RFS and PFS for patients affected by T1 BCa and should be included in innovative prognostic nomograms

Radiomics and Magnetic Resonance Imaging of Rectal Cancer: From Engineering to Clinical Practice

While cross-sectional imaging has seen continuous progress and plays an undiscussedpivotal role in the diagnostic management and treatment planning of patients with rectal cancer, alargely unmet need remains for improved staging accuracy, assessment of treatment response andprediction of individual patient outcome. Moreover, the increasing availability of target therapies hascalled for developing reliable diagnostic tools for identifying potential responders and optimizingoverall treatment strategy on a personalized basis. Radiomics has emerged as a promising, still fullyevolving research topic, which could harness the power of modern computer technology to generatequantitative information from imaging datasets based on advanced data-driven biomathematicalmodels, potentially providing an added value to conventional imaging for improved patient manage-ment. The present study aimed to illustrate the contribution that current radiomics methods appliedto magnetic resonance imaging can offer to managing patients with rectal cancer

Penile metastasis from primary cholangiocarcinoma: the first case report

BACKGROUND: Metastatic penile carcinoma derived from cholangiocarcinoma (CCA) has not been previously reported in the literature. Common metastatic sites for CCA include the regional lymph nodes and adjacent organs. CCAs are not highly vascularised tumours, making hematogenous metastases uncommon. Hematogenous CCA metastases commonly occur at distant organs such as the lungs, adrenal glands, and bones. Median survival for patients with metastatic disease is generally less than 1 year. CASE PRESENTATION: A 74-year-old Caucasian man consulted us after having undergone penile ultrasonography for pain and increased thickness at the base of the penis after self-examination. The patient presented with a history of hepatitis C-related cirrhosis and intrahepatic CCA, diagnosed 3 years previously. A biopsy of the corpora cavernosa on both sides revealed a carcinoma harbouring the same histological and immunophenotypical features as the primary hepatic lesion. CONCLUSIONS: To date, there is no case of penile or urogenital system metastasis from CCA described in the literature. Therefore, this article represents the first case report of penile metastasis from CCA

Successful treatment with pollen extract of hematospermia in patients with xanthogranolomatous prostatitis

Introduction: The aim of this study was to report our experience in the management of hematospermia observed in 16 patients suffering from xanthogranulomatous prostatitis. Methods: Recurrent episodes of hematospermia were the onset symptom in all patients, and in 25% of patients it was combined with fever. All patients reported PSA value elevation and the digital rectal examination (DRE) revealed an increase of the gland size and of its consistency in all cases. In all patients, the hematospermia was treated with the oral administration of two tablets of pollen extract in a single (1 g) dose daily for 30 days. Results: Sixteen patients were observed between 2008 and 2016, referring hematospermia, progressive lower urinary tract symptoms (LUTS), and serum PSA level increase. To exclude the prostate cancer presence all patients were submitted to transperineal TRUS guided biopsy. In all the patients complete resolution of hematospermia was achieved treatment with pollen extract. All patients were subsequently treated for LUTS (alpha-adrenergic blockers), but none reported any significant improvement of symptoms. Basing on these pieces of evidence, after 90 days of alpha-blockers therapy, all patients underwent bipolar TURP. Histological examination of resected prostatic tissue revealed in all patients the diagnosis of xanthogranulomatous prostatitis. Conclusions: Patients with xanthogranulomatous prostatitis especially experience irritative symptoms, sometimes combined with fever or hematospermia. Hematospermia as the onset symptom has not been reported so far. The administration of the pollen extract for 30 days was associated with a complete resolution of hematospermia
