Summary Background The ICON7 trial previously reported improved progression-free survival in women with ovarian cancer with the addition of bevacizumab to standard chemotherapy, with the greatest effect in patients at high risk of disease progression. We report the final overall survival results of the trial. Methods ICON7 was an international, phase 3, open-label, randomised trial undertaken at 263 centres in 11 countries across Europe, Canada, Australia and New Zealand. Eligible adult women with newly diagnosed ovarian cancer that was either high-risk early-stage disease (International Federation of Gynecology and Obstetrics [FIGO] stage I–IIa, grade 3 or clear cell histology) or more adv…
Autoimmune pancreatitis: A challenging diagnostic puzzle for clinicians
2010
Autoimmune pancreatitis is a form of pancreatitis with autoimmune stigmata that may present as either focal or diffuse gland involvement. In focal forms, autoimmune pancreatitis shares demographic, clinical, biochemical and imaging features with pancreatic cancer. Since autoimmune pancreatitis is a benign disease and steroid therapy can rapidly resolve symptoms, improve radiological findings and avoid unnecessary surgery, the current clinical challenge is how to differentiate autoimmune pancreatitis from pancreatic neoplasia. Even though definitive diagnosis of the disease is difficult, several diagnostic criteria have been proposed and progress has been made in imaging studies. The managem…
Amphiregulin activates human hepatic stellate cells and is upregulated in non alcoholic steatohepatitis
2015
AbstractAmphiregulin (AR) involvement in liver fibrogenesis and hepatic stellate cells (HSC) regulation is under study. Non-alcoholic fatty liver disease (NAFLD) and its more severe form non-alcoholic steatohepatitis (NASH) may progress to cirrhosis and hepatocellular cancer (HCC). Our aim was to investigate ex vivo the effect of AR on human primary HSC (hHSC) and verify in vivo the relevance of AR in NAFLD fibrogenesis. hHSC isolated from healthy liver segments were analyzed for expression of AR and its activator, TNF-α converting enzyme (TACE). AR induction of hHSC proliferation and matrix production was estimated in the presence of antagonists. AR involvement in fibrogenesis was also ass…
Asymptotic modeling of electrochemical signaling: Testing Zn in urine for non-invasive bladder cancer diagnosis
2021
Abstract A theoretical model on chemical signaling for diagnosis based on the combination of signals for marker and inert and/or interfering metabolites is described. The model yields asymptotic relationships between the intensities of the signals representative of marker and accompanying metabolites compensating concentration fluctuations. The model fits well with voltammetric features associated to the oxidation of different urine metabolites and Zn(II) reduction in the same urine samples after alkaline digestion. As a result, a non-invasive electrochemical detection of urothelial carcinoma (bladder cancer, BC) is reported. Different diagnostic criteria are described all displaying high s…

T1HG Bladder Tumours: So Many Papers, Do We Need Them? Yes, We Do!
2009
“How many roads a man must walk on….” and how many papers we must read and write… to put down the final word on the appropriate management of high risk NMI-BC. Although it is more than 20 years that we take notice of promises on biological markers predictive of the behaviour of NMI-BC, till today we can only base our decisions on clinical and pathological data. Consequently, we need exchange of experiences and reports on the outcome of these patients. The aim of the treatment of T1 bladder tumours is to minimize mortality while assuring reduced morbidity and good quality of life. A conservative approach is, obviously, not applicable to all T1HG tumours. We need to identify unequivocal selec…

Long-term results of ileocecal continent urinary diversion in patients treated with or without previous pelvic irradiation
2003
Purpose: Patients who receive pelvic irradiation may require urinary diversion to manage complications resulting from progressive malignancy or radiotherapy. The choice of urinary diversion is an important issue and remains controversial. We characterized the long-term outcome of urinary diversion with a continent ileocecal reservoir in patients who received pelvic irradiation versus those who underwent urinary diversion without previous irradiation. Materials and Methods: Continent urinary diversion with an ileocecal reservoir (Mainz pouch 1) was performed in 36 irradiated patients in a 9-year period. Morbidity, mortality, the reoperative rate and parameters associated with the surgical pr…
Clinical Scenario: Unexpected Positive Nodes at Radical Cystectomy
2014
Positive lymph nodes are found in 20–30 % of patients undergoing radical cystectomy for bladder cancer. Their presence is associated with poor survival in the majority. Super-extended lymph node dissection is recommended in the presence of positive lymph nodes to possibly improve oncologic outcome. In patients with unsuspicious lymph nodes, dissection should be performed at least up to the common iliac vessels. Even in the presence of lymph node metastases cystectomy is indicated to reduce local tumor complications. The type of urinary diversion should not be altered by lymph node positivity unless the diversion would otherwise negatively influence the extent of the procedure.
hTERT mRNA expression in urine as a useful diagnostic tool in bladder cancer. Comparison with cytology and NMP22 BladderCheck Test®
2018
Abstract Introduction To study the relationship between quantitative mRNA determination (hTERT) in patients with bladder tumor, history of bladder tumor, and in subjects without a history of this neoplasia. Material and methods A prospective randomized controlled study with 91 subjects included. The value of mRNA-hTERTN was determined in 63 patients with a history or suspicion of bladder tumor and in 28 controls. Urine samples were sent for evaluation of the mRNA level (hTERT), the cytological study and the NMP22 result. Results Differences were observed in mean hTERTN levels in each of the groups: tumor presence 21.33 ± 40.66, tumor history 2.16 ± 2.67, controls 0.9 ± 1.75 (p Conclusions …
