    Objectives: To evaluate if the Human epidermal growth factor receptor 2 (HER-2) expression levels may be used as potential prognostic marker in high grade T1 blad- der cancer (T1G3) Methods: Specimens from transurethral resection of bladder tumour (TURBT) of 103 patients with high-grade T1 bladder cancer were collected. This pathologic database was reviewed. Four-year follow-up data were matched with pathologic data. Eighty-three patients entered the study. HER-2 staining was performed. Patients were grouped for HER-2 status. Statistical analysis included Kaplan Meier survival analysis and Log-rank test. Results: Pathological review of TURBT specimens confirmed high-grade T1 transitional cell bladder cancer in all patients. Median follow-up was 12 months (mean 23,5; range 3-48). Twenty-one patients (25.4%) present strong HER-2 expression (3+), 28 (33.7%) moderate expression (2+), 26 (33.7%) weak staining (1+) and 8 (9.6%) negative expression (0). Thirty- one patients of 83 (37.4%) had not evidence of disease, 41 (49.4%) recurred, 11 (13.2%) had a progression of disease. Forty-one patients had high grade T1 recurrence. Patients with HER-2 status 0 did not showed progression of disease. Patients with HER-2 status 3+, undergoing cys- tectomy because progression of disease, had a pathological stage > pT2 and a nodal involve- ment. Median Disease-Free Survival (DFS) for all patients was 12 months (DFS probability (pDFS) = 49.3%; 95% CI, -11.1/+10.1). Median DFS in HER-2 groups was 8 (pDFS 37.5%; 95% CI,-28.8/+29.9), 24 (pDFS 46.1%; 95% CI,-19.5/+17.5), 20 (pDFS 46.4%; 95% CI,-18.8/+16.9) and 10 months (pDFS 47.6%; 95% CI,-21.9/+19.1) respectively in HER-2 status 0,1+,2+,3+. Log-Rank test is not statistically significant (p = 0,39). Conclusions: This study showed that HER-2 expression does not represent a prognostic mark- er of recurrence/progression of disease in high-grade T1 bladder cancer

    Acute hemodynamic effects of inhaled nitric oxide, dobutamine and a combination of the two in patients with mild to moderate secondary pulmonary hypertension

    INTRODUCTION: The use of low-dose dobutamine to maintain hemodynamic stability in pulmonary hypertension may have a detrimental effect on gas exchange. The aim of this study was to investigate whether inhaled nitric oxide (INO), dobutamine and a combination of the two have beneficial effects in patients with end-stage airway lung disease and pulmonary hypertension. METHOD: Hemodynamic evaluation was assessed 10 min after the administration of each drug and of their combination, in 28 candidates for lung transplantation. RESULTS: Administration of INO caused a reduction in mean pulmonary arterial pressure (MPAP), an increase in PaO(2) with a significant reduction in venous admixture effect (Q(s)/Q(t)).Dobutamine administration caused an increase in cardiac index and MPAP, with a decrease in PaO(2) as a result of a higher Q(s)/Q(t). Administration of a combination of the two drugs caused an increase in the cardiac index without MPAP modification and an increase in PaO(2) and Q(s)/Q(t). CONCLUSION: Dobutamine and INO have complementary effects on pulmonary circulation. Their association may be beneficial in the treatment of patients with mild to moderate pulmonary hypertension

    Bladder Epicheck Test: A Novel Tool to Support Urothelial Carcinoma Diagnosis in Urine Samples

    Bladder cancer and upper urothelial tract carcinoma are common diseases with a high risk of recurrence, thus necessitating follow-up after initial treatment. The management of non-muscle invasive bladder carcinoma (NMIBC) after transurethral resection involves surveillance, intravesical therapy, and cytology with cystoscopy. Urinary cytology, cystoscopy, and radiological evaluation of the upper urinary tract are recommended during follow-up in the international urological guidelines. Cystoscopy is the standard examination for the first assessment and follow-up of NMIBC, and urine cytology is a widely used urinary test with high sensitivity for high-grade urothelial carcinoma (HGUC) and carcinoma in situ (CIS). In recent years, various urinary assays, including DNA methylation markers, have been used to detect bladder tumors. Among these, the Bladder EpiCheck test is one of the most widely used and is based on analysis of the methylation profile of urothelial cells to detect bladder neoplasms. This review assesses the importance of methylation analysis and the Bladder EpiCheck test as urinary biomarkers for diagnosing urothelial carcinomas in patients in follow-up for NMIBC, helping cytology and cystoscopy in doubtful cases. A combined approach of cytology and methylation analysis is suggested not only to diagnose HGUC, but also to predict clinical and histological recurrences

    Fluorescence-guided lung nodule identification during minimally invasive lung resections

    Get PDF
    In the last few years, minimally invasive surgery has become the standard routine practice to manage lung nodules. Particularly in the case of robotic thoracic surgery, the identification of the lung nodules that do not surface on the visceral pleura could be challenging. Therefore, together with the evolution of surgical instruments to provide the best option in terms of invasiveness, lung nodule localization techniques should be improved to achieve the best outcomes in terms of safety and sensibility. In this review, we aim to overview all principal techniques used to detect the lung nodules that do not present the visceral pleura retraction. We investigate the accuracy of fluorescence guided thoracic surgery in nodule detection and the differences among the most common tracers used

    MALAT1 and HOTAIR long non-coding RNAs play opposite role in estrogen-mediated transcriptional regulation in prostate cancer cells

    In the complex network of nuclear hormone receptors, the long non-coding RNAs (lncRNAs) are emerging as critical determinants of hormone action. Here we investigated the involvement of selected cancer-associated lncRNAs in Estrogen Receptor (ER) signaling. Prior studies by Chromatin Immunoprecipitation (ChIP) Sequencing showed that in prostate cancer cells ERs form a complex with the endothelial nitric oxide synthase (eNOS) and that in turn these complexes associate with chromatin in an estrogen-dependent fashion. Among these associations (peaks) we focused our attention on those proximal to the regulatory region of HOTAIR and MALAT1. These transcripts appeared regulated by estrogens and able to control ERs function by interacting with ER\u3b1/ER\u3b2 as indicated by RNA-ChIP. Further studies performed by ChIRP revealed that in unstimulated condition, HOTAIR and MALAT1 were present on pS2, hTERT and HOTAIR promoters at the ERE/eNOS peaks. Interestingly, upon treatment with17\u3b2-estradiol HOTAIR recruitment to chromatin increased significantly while that of MALAT1 was reduced, suggesting an opposite regulation and function for these lncRNAs. Similar results were obtained in cells and in an ex vivo prostate organotypic slice cultures. Overall, our data provide evidence of a crosstalk between lncRNAs, estrogens and estrogen receptors in prostate cancer with important consequences on gene expression regulatio

    First-line ICIs in renal cell carcinoma

    Treatment of metastatic renal cell carcinoma (mRCC) has radically changed, switching from interferon alfa (IFN-α) and high-dose interleukin−2 (HD IL−2) to new targeted therapies directed against tumoral neoangiogenesis, the mammalian target of the rapamycin (mTOR) pathway and immune checkpoints. Of note, the inhibition of immune checkpoints restores antitumor immune response, therefore promoting immune-mediated elimination of neoplastic cells. The best example of this targeted treatment is represented by PD-1/PD-L1 inhibition that has become the standard of care in mRCC treatment and has improved mRCC patients’ prognoses after failure of other targeted therapies. In this manuscript, we review the main therapeutic protocols adopted for mRCC, based on the use of immune checkpoint inhibitors (ICIs) alone or combined with other drugs

    No full text
    Background: Double-blind ureteral duplication (DBUD) is a rare condition in which one of the ureters in a duplicated system has no communication with the bladder or the renal pelvis. Case Presentation: We present a neonatal case of DBUD in a newborn girl, associated with a non-functional kidney, initially identified as an abdominal cystic anechoic mass during antenatal ultrasound. A stepwise diagnostic and management approach was undertaken, including prenatal and postnatal imaging, multidisciplinary consultation, and surgical intervention. Conclusion: Establishing a diagnosis of DBUD requires a systematic approach, incorporating comprehensive prenatal and postnatal assessments. This case is the first reported instance of DBUD diagnosed and treated in the neonatal period, highlighting the importance of early detection and intervention

    Giant spermatic cord liposarcoma

    We report a case of giant spermatic cord liposarcoma (SCL) in an 81-year-old patient, presenting with a huge scrotal mass that reached up to the knee joint. SCL is a rare tumor, and about 200 cases have been reported in the literature so far. Although 20% of liposarcomas arise in the retroperitoneum, only 0.1% present as incidental inguinal hernias. The occasional presence of myxoid stroma in well-differentiated liposarcomas can lead to confusion with myxoid sarcoma subtypes. Correct diagnosis is critical and reflects remarkable differences in behavior and therapeutic choices
