    In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today’s technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics

    In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries

    Purpose: We evaluated modified inguinal lymphadenectomy in the treatment of penile carcinoma, analyzing the rate of complications compared to complete inguinal lymphadenectomy, the complications in performing lymphadenectomy and penectomy concomitantly, and the long-term locoregional recurrence rate. \ Materials and Methods: A total of 26 patients with squamous cell carcinoma of the penis were clinically assessed, and underwent penectomy and bilateral modified inguinal lymphadenectomy at the same operative time. Frozen section analysis of lymph nodes was performed and if metastases were detected a complete ipsilateral inguinal dissection was performed. Results: A total of 52 modified lymphadenectomies were performed. In 10 procedures lymph node metastasis was present. Clinical staging presented false-positive and false-negative rates of 50% and 7.9%, respectively. The complication rate for modified lymphadenectomy was 38.9% and for complete inguinal lymphadenectomy it was 87.5%. Followup ranged from 5 to 112 months and mean followup of recurrence-free cases was 78 months (range 38 to 112). A total of 18 patients underwent bilateral negative modified inguinal lymphadenectomy and 2 of these experienced locoregional recurrence within 2 years after surgery. Conclusions: Modified inguinal lymphadenectomy causes a lower complication rate than complete inguinal lymphadenectomy. Bilateral modified inguinal lymphadenectomy performed at the same time as penectomy does not increase the complication rate. When frozen section analysis is negative bilaterally, 5.5% of inguinal regions might still harbor occult metastasis. Modified inguinal lymphadenectomy is recommended as a staging procedure in all patients with T2-3 penile carcinoma. A straight followup is required for 2 years since all recurrence was within this period.172249850
