    Objective: To assess accuracy of University of California Los Angeles Integrated Staging System (UISS), Stage, Size, Grade and Necrosis (SSIGN) score, Leibovich score and GRade, Age, Nodes and Tumor (GRANT) score, the ASSURE (Adjuvant Sunitinib or Sorafenib vs. placebo in resected Unfavorable REnal cell carcinoma) score models and seventh American Joint Committee on Cancer (AJCC)/TNM staging system in predicting recurrence-free survival (RFS) in surgically-treated non-metastatic clear cell renal cell carcinoma (ccRCC) patients. Materials and methods: Kaplan-Meier curves and the log-rank test tested RFS according to risk groups among the UISS, SSIGN, Leibovich and GRANT models and the AJCC/TNM system. The Heagerty's C-index for survival tested for discrimination of each model at different time points after nephrectomy. Results: Three hundred and fifty-eight M0 ccRCC patients were included. RFS significantly differed among each risk category for all models (P < 0.001). SSIGN showed the highest c-index over time (from 0.89 at 6-month to 0.82 at 60-month), followed by Leibovich (from 0.89–0.82), AJCC/TNM stage (from 0.82–0.77), ASSURE (from 0.81 to 0.76), GRANT (from 0.83–0.73) and UISS (from 0.76–0.72). For all models, peak discriminatory ability was reached before 12 months. The most prominent decline occurred within 24 months and reaches the lowest discriminatory ability at 60 months. Conclusions: Predictive models, with preference for SSIGN and Leibovich scores, are reliable to predict recurrence after nephrectomy and should be recommended to tailor postoperative surveillance protocols

    Salvage radical prostatectomy after primary radiotherapy (sRP) is considered a challenging procedure. We highlight the complications of sRP and detail critical surgical steps to help prevent them. A nonsystematic literature review in PubMed using the term “salvage radical prostatectomy” was performed on December 1, 2021. Salvage robot-assisted RP (sRARP) cases and imaging materials were used to create an educational video providing practical examples. Owing to radiation-induced changes in the prostate and surrounding tissues after radiotherapy, sRP is typically more challenging than primary RP. Among its critical steps are incision of the endopelvic fascia, bladder neck dissection with attempts at sparing the neck, development of posterior planes between the prostate and rectum, and dissection of the prostatic apex. Complication rates are significant, in particular for bladder neck contracture (0–16%) and anastomotic leakage (10–33%). Rectal injury is now rare (<2%) but still feared; careful adherence to surgical principles is required to avoid this complication. Functional outcomes are nonoptimal, with a high risk of urinary incontinence (severe incontinence in ∼25% of men). sRARP is a challenging urological procedure and should be performed by experienced surgeons. Thorough knowledge of the surgical anatomy and a meticulous technique for the most difficult surgical steps are crucial to minimise complications and to improve patient outcomes. Patient summary: In patients with prostate cancer, removal of the prostate because of cancer recurrence after primary treatment with radiotherapy can be difficult because of radiation-induced tissue damage. This challenging procedure should be performed by experienced surgeons to minimise the risk of complications

    Self-Rated Quality of Life in Celiac Disease

    As much as 1% of the gluten-consuming world is gluten-intolerant. New screening methods are increasingly identifying gluten intolerance in individuals previously free from health problems. The often-abrupt major change in diet may adversely affect the patient's quality of life. Our aim was to evaluate self-perceived quality of life in a large cohort of adult celiac patients after at least one year of a gluten-free diet. In all 581 members (410 females) of five regional celiac societies were on a gluten-free regimen for at least one year. In this cross-sectional study, a modified version of the Zung Self-Rating Depression Scale was administered to the 581 patients from five Italian regions. Most patients correctly defined celiac disease, and compliance with the gluten-free diet was high, although reporting bias cannot be excluded. Most felt well (83.6% "very well" and "well"); consequently, anxiety and depression scores were low. Happiness also scored low. Most participants did not feel that a gluten-free life differentiated them from the general population. Women and patients diagnosed after 20 years of age had better dietary compliance, but more problems in their social life. Happiness scores were higher in patients diagnosed before 20 years of age. Anxiety and depression were infrequent in this group; however, anxiety was frequently related to feeling different from the general population, and depression to an unsatisfactory sexual life. In conclusion, celiac disease does not appear to be associated to a low level of self-perceived quality of life in members of the Italian Celiac Society

    Currently, the majority of prostate cancer (PCa) recurrences after non-surgical first-line treatment are managed with androgen-deprivation therapy (ADT). Salvage radical prostatectomy (sRP) is a curative alternative to ADT but yields significant morbidity. Preliminary evidence from focal salvage treatments shows similar oncological control but lower morbidity compared to sRP. Among available ablative focal energies, irreversible electroporation (IRE) is a treatment modality that proved promising, especially in treating apical lesions, where PCa most often recurs. Our aim is to test the safety of salvage IRE for recurrent PCa. We performed a single-arm pilot feasibility study (IDEAL stage 2a): SAFE, SAlvage Focal irreversible Electroporation for recurrent localized PCa. Twenty patients with biopsy-proven PCa recurrence after primary non-surgical (radiation or ablation) treatment were included. All men will undergo mpMRI ± targeted biopsies, pre-operative PSMA-PET staging before inclusion and sIRE. Outcomes will be evaluated through internationally validated questionnaires and morbidity scales. All men will undergo a control biopsy at one year. Primary objectives were the evaluation of the safety of sIRE (and patients' quality of life) after treatment. Secondary objectives were the evaluation of functional outcomes, namely, continence and erectile function changes and evaluation of short-term oncological efficacy. SAFE is the second pilot study to evaluate sIRE and the first one performed according to the most recent diagnostic and staging imaging standards. sIRE may provide a curative option for recurrent PCa together with lower comorbidities compared to sRP

    Background: Non-celiac gluten sensitivity (NCGS) is still an undefined syndrome with several unsettled issues despite the increasing awareness of its existence. We carried out a prospective survey on NCGS in Italian centers for the diagnosis of gluten-related disorders, with the aim of defining the clinical picture of this new syndrome and to establish roughly its prevalence compared with celiac disease. Methods: From November 2012 to October 2013, 38 Italian centers (27 adult gastroenterology, 5 internal medicine, 4 pediatrics, and 2 allergy) participated in this prospective survey. A questionnaire was used in order to allow uniform and accurate collection of clinical, biochemical, and instrumental data. Results: In total, 486 patients with suspected NCGS were identified in this 1-year period. The female/male ratio was 5.4 to 1, and the mean age was 38 years (range 3-81). The clinical picture was characterized by combined gastrointestinal (abdominal pain, bloating, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and systemic manifestations (tiredness, headache, fibromyalgia-like joint/muscle pain, leg or arm numbness, 'foggy mind,' dermatitis or skin rash, depression, anxiety, and anemia). In the large majority of patients, the time lapse between gluten ingestion and the appearance of symptoms varied from a few hours to 1 day. The most frequent associated disorders were irritable bowel syndrome (47%), food intolerance (35%) and IgE-mediated allergy (22%). An associated autoimmune disease was detected in 14% of cases. Regarding family history, 18% of our patients had a relative with celiac disease, but no correlation was found between NCGS and positivity for HLA-DQ2/-DQ8. IgG anti-gliadin antibodies were detected in 25% of the patients tested. Only a proportion of patients underwent duodenal biopsy; for those that did, the biopsies showed normal intestinal mucosa (69%) or mild increase in intraepithelial lymphocytes (31%). The ratio between suspected NCGS and new CD diagnoses, assessed in 28 of the participating centers, was 1.15 to 1. Conclusions: This prospective survey shows that NCGS has a strong correlation with female gender and adult age. Based on our results, the prevalence of NCGS seems to be only slightly higher than that of celiac disease.
