The role of multiparametric MRI in active surveillance for low-risk prostate cancer: The ROMAS randomized controlled trial

BackgroundWe aim to evaluate the impact of multiparametric magnetic resonance imaging and fusion-target biopsy for early reclassification of patients with low-risk Prostate Cancer in a randomized trial.Materials and methodsBetween 2015 and 2018, patients diagnosed with Prostate Cancer after random biopsy fulfilling PRIAS criteria were enrolled and centrally randomized (1:1 ratio) to study group or control group. Patients randomized to study group underwent multiparametric magnetic resonance imaging at 3 months from enrollment: patients with positive findings (PIRADS-v2>2) underwent fusion-target biopsy; patients with negative multiparametric magnetic resonance imaging or confirmed ISUP - Grade Group 1 at fusion-target biopsy were managed according to PRIAS schedule and 12-core random biopsy was performed at 12 months. Patients in control group underwent PRIAS protocol, including a confirmatory 12-core random biopsy at 12 months. Primary endpoint was a reduction of reclassification rate at 12-month random biopsy in study group at least 20% less than controls. Reclassification was defined as biopsy ISUP Grade Group 1 in >2 biopsy cores or disease upgrading.ResultsA total of 124 patients were randomized to study group (n = 62) or control group (n = 62). Around 21 of 62 patients (34%) in study group had a positive multiparametric magnetic resonance imaging, and underwent fusion-target biopsy, with 11 (17.7%) reclassifications. Considering the intention-to-treat population, reclassification rate at 12-month random biopsy was 6.5% for study group and 29% for control group, respectively (P < 0.001).ConclusionsThe early employment of multiparametric magnetic resonance imaging for active surveillance patients enrolled after random biopsy consents to significantly reduce reclassifications at 12-month random biopsy.     

Pretransplant solid organ malignancy and organ transplant candidacy: A consensus expert opinion statement

Patients undergoing evaluation for solid organ transplantation (SOT) often have a history of malignancy. Although the cancer has been treated in these patients, the benefits of transplantation need to be balanced against the risk of tumor recurrence, especially in the setting of immunosuppression. Prior guidelines of when to transplant patients with a prior treated malignancy do not take in to account current staging, disease biology, or advances in cancer treatments. To develop contemporary recommendations, the American Society of Transplantation held a consensus workshop to perform a comprehensive review of current literature regarding cancer therapies, cancer stage-specific prognosis, the kinetics of cancer recurrence, and the limited data on the effects of immunosuppression on cancer-specific outcomes. This document contains prognosis based on contemporary treatment and transplant recommendations for breast, colorectal, anal, urological, gynecological, and nonsmall cell lung cancers. This conference and consensus documents aim to provide recommendations to assist in the evaluation of patients for SOT given a history of a pretransplant malignancy.     

Schwannoma of the nasal septum: a case report with review of the literature

Schwannomas are neurogenic neoplasms rarely found in the sinonasal tract, where localization to the nasal septum is exceedingly rare (only 11 cases have been described in the western literature). We report the case of a 29-year-old white male with a schwannoma completely filling the left nasal fossa and arising from the bony part of the septum. A computer tomography (CT) scan and a biopsy suggestive of benign schwannoma were obtained before the lesion was removed by a degloving approach. The preoperative diagnosis of nasal septum schwannoma was confirmed. The patient is asymptomatic and without endoscopic evidence of recurrence 7 years after surgery. A review of the literature with particular emphasis on the clinical presentation, histological features, differential diagnosis and therapeutic options for such a rare lesion is included.

Prevalence of hepatitis C virus genotypes in southern Italy

HCV is ubiquitous. In 50% of all cases it causes chronic hepatitis that often evolves into liver cirrhosis and hepatocellular carcinoma. Recently HCV has been classified in 5 genotypes by Okamoto. The purpose of this study is to evaluate the prevalence of 5 genotypes in Campania, a region of Southern Italy, where the prevalence of anti-HCV antibodies ranges from 0.87 to 4%, and to evaluate the correlation between the HCV genotypes and the severity of histological damage. One hundred and thirty-five anti-HCV positive patients were enrolled and tested by PCR to identify HCV-RNA. One hundred and twenty-four patients resulted HCV-RNA positive. Genotyping was performed as described by Okamoto et al. with minor modifications of the specific primer to type III proposed by Silini et al. Eight patients were negative for all genotypes. Eight patients were positive for type I(1a), 61 for type II(1b), 39 for type III(2a), 11 for type IV(2b) and 1 for type V(3a). In 4 cases two different genotypes were present in the same sample [II(1b)-IV(2b), III(2a)-II(1b) twice, III(2a)-IV(2b)]. Histological evaluation of liver damage showed: CPH (22 cases), minimal CAH (56), severe CAH (31) and liver cirrhosis (15). There was no statistically significant correlation between the 5 genotypes and the severity of histological damage. Data on the prevalence of genotype II(1b) in Italy are similar to those reported for other European countries. The prevalence of genotypes in Southern Italy is similar to that reported in the population of Northern Italy.     

Arthrogryposis,renal dysfunction and cholestasis syndrome: Report of five patients from three Italian families

We report on five patients from three families with neurogenic arthrogryposis, cholestasis and tubular renal dysfunction. Despite a similar clinical picture the liver histology showed a broad pathological spectrum, ranging from pigment storage to parenchymal giant cell transformation and ductopenia. The findings are compared with those of other cases from the literature in search of a correct nosology of the syndrome characterized by arthrogryposis, renal and liver disease.Conclusion We propose to consider the picture of arthrogryposis, renal tubular dysfunction and cholestasis as a single syndrome.     

Emergency laparoscopic surgery: a hospital's experience]

BACKGROUND AND AIM: The wide diffusion and increasing use of laparoscopic surgery prompts the authors to broaden discussion to its validity and diagnostic-therapeutic use in emergency abdominal surgery. The aim was to evaluate the efficacy of laparoscopic surgery in the light of reports in the international literature and in relation to the situation in our hospital. METHODS: From April 1994 to May 1998, out of 1016 emergency abdominal operations performed at our hospital, 783 (77.5%) used a laparoscopic approach for diagnostic and therapeutic purposes: intestinal occlusion: 26 cases; gastrointestinal ulcer pathology: 15 cases; hepatobiliary pathology: 398 cases; "pelvic" pathology: 305 cases; colic pathology: 39 cases. These represent 24.4% of all laparoscopic procedures carried out during the same period. We preferred to use immediate laparotomic access in patients with the following characteristics: anamnesis of previous surgery for malignant pathologies; anamnesis of more than two major abdominal operations; massive intestinal distension; patients whose general conditions were a contraindication to a laparoscopic approach. RESULTS: The conversion rate was 6.2% (49 cases) with morbidity of 3.4% (25 cases) and a mortality rate of 0.2% (2 cases). A final diagnosis was made in 763 patients (97.4%) with the possibility of treating 719 of them (94.2%), again using a laparoscopic approach. CONCLUSIONS: It is right to regard the laparoscopic approach in emergency abdominal surgery as a feasible and safe model, offering a high potential for diagnosis and therapy if appropriately performed by an expert and well coordinated team. The increased experience of mini-invasive surgery and the improved range of instruments available make the laparoscopic approach a valid alternative to laparotomy, even in the event of emergency abdominal pathologies.
