P2-178: Mediastinal-based treatment decision tree in stage IIIA-N2 non-small cell lung cancer
Benefit of surgery after chemoradiotherapy in stage IIIB (T4 and/or N3) non–small cell lung cancer
AbstractObjective: The purpose of this study was to evaluate postchemoradiotherapy surgery in stage IIIB non–small cell lung cancer. Methods: Forty patients with stage IIIB non–small cell lung cancer were included in this phase II study. A preoperative diagnosis of stage IIIB cancer was based on mediastinoscopy or a thoracotomy in all patients. Induction treatment included two cycles of cisplatin (100 mg/m2, day 1), 5-fluorouracil (1 g/m2, days 1-3), and vinblastine (4 mg/m2, day 1) combined with 42 Gy of hyperfractionated radiotherapy delivering 21 Gy in two sessions. Patients with a clinical response were offered surgery. Results: The minimum follow-up for survivors was 48 months. Thirty patients had a T4 lesion and 18 had N3 disease. Twenty-nine patients (73%) had a clinical objective tumor response after induction treatment. These 29 patients underwent thoracotomy, and a complete resection was performed in 23 (58%). Two postoperative deaths occurred (7%). Four patients had a pathologic complete response at the time of surgery (10%). The 5-year survival is 19% for the overall population. When only patients who had persistent viable tumor cells at surgery are considered (n = 25), the 5-year survival is 28%. The 5-year survival is 42% for patients having no mediastinal lymph node involvement at the time of surgery and being treated with complete resection. Conclusion: This study shows that surgery, when feasible, is associated with a 28% long-term survival for patients in whom chemoradiotherapy alone fails to control disease

BACKGROUND
How to evaluate the risk/benefit of trimodality therapy in locally advanced non-small-cell lung cancer
The trimodality approach represented by concurrent chemoradiotherapy followed by surgical resection is a highly effective, but potentially toxic therapy for locally advanced non-small-cell lung cancer (NSCLC). In this review, we discuss the current status of this therapy in patients with mediastinal node-positive (N2) stage III NSCLC or superior sulcus tumor, and present an overview of the principles for optimisation of the risk/benefit. Numerous clinical questions remain, and enrolment of patients into well-designed clinical trials should be encouraged
LICSTER -- A Low-cost ICS Security Testbed for Education and Research
Unnoticed by most people, Industrial Control Systems (ICSs) control entire
productions and critical infrastructures such as water distribution, smart grid
and automotive manufacturing. Due to the ongoing digitalization, these systems
are becoming more and more connected in order to enable remote control and
monitoring. However, this shift bears significant risks, namely a larger attack
surface, which can be exploited by attackers. In order to make these systems
more secure, it takes research, which is, however, difficult to conduct on
productive systems, since these often have to operate twenty-four-seven.
Testbeds are mostly very expensive or based on simulation with no real-world
physical process. In this paper, we introduce LICSTER, an open-source low-cost
ICS testbed, which enables researchers and students to get hands-on experience
with industrial security for about 500 Euro. We provide all necessary material
to quickly start ICS hacking, with the focus on low-cost and open-source for
education and research
