The significance of sentinel lymph node (SLN) in surgical treatment of endometrial cancer
Uvod: Trend porasta ucestalosti obolevanja i umiranja od karcinoma endometrijuma, koji se
poslednjih godina registruje širom sveta, uslovio je da ovo oboljenje postane jedan od vodecih
javno-zdravstvenih problema u populaciji žena širom sveta. Preživljavanje obolelih od
endometrijalnog karcinoma je skoro 90% , dok se taj procenat drasticno smanjuje ukoliko su
limfni cvorovi male karlice pozitivni na metastatsku bolest i iznosi oko 50% . Istraživanja su
pokazala da ucestalost metastaza u limfaticima iznosi oko 10% i uveliko zavisi od klinickih,
patoanatomskih i morfoloških karakteristika samog oboljenja. Meutim, limfadenektomija u
tretmanu pacijentkinja obolelih od karcinoma tela materice je predmet mnogih debata na
nacionalnim i meunarodnim skupovima što jasno ukazuje na cinjenicu da ne postoji
konzistentan stav o znacaju njene uloge u terapijskom pristupu ovog oboljenja. Naime,
mnogobrojna istraživanja su pokazala su da je ucestalost ozbiljnih komplikacija kod
pacijentkinja kod kojih je raena sistematska limfadenektomija, znacajno viša u odnosu na
grupe pacijentkinja koje nisu bile podvrgnute ovoj opsežnijoj hirurškoj proceduri. Iz tog
razloga, veliki broj studija je sproveden u cilju identifikacije najoptimalnijeg nacina selekcije
pacijentkinja kod kojih je zaista neophodno da se uradi sistematska limfadenektomija. U tom
smislu, u cilju smanjenja postoperativnog morbiditeta, poslednjih godina, sve više se ispituje
uloga biopsije limfnog cvora stražara - SLN (engl. Sentinel node lymphadenectomy) u proceni
statusa limfnog sisitema male karlice u grupi žena obolelih od karcinoma endometrijuma.
Ciljevi: (I) Odreivanje stope detekcije SLN (engl. Sentinel node lymphadenectomy) u uzorku
žena sa ranim stadijumom karcinoma endometrijuma; (II) Ispitivanje vrednosti stope lažno
negativnih nalaza, senzitivnosti, specificnosti, pozitivne i negativne prediktivne vrednosti SLN
(engl. Sentinel node lymphadenectomy) u proceni statusa limfnih cvorova male karlice; (III)
Uporeivanje histološkog nalaza limfnih cvorova dobijenog H&E (hematoxylin and eosin)
tehnikom i ostalim limfnim cvorovima dopunskom tehnikom ultrastadiranja - IHH (engl.
immunohistochemistry), kada je tehnikom H&E (hematoxylin and eosin) potvreno odsustvo
metastaza; (IV) Ispitivanje korelacije izmeu prisusutva metastaza u SLN (engl. Sentinel node
lymphadenectomy) sa postoperativnim histološkim nalazom i stepenom zrelosti
endometrijalnog karcinoma.

"Narodni front" u Beogradu u periodu od februara 2015. do juna 2016 godine...Introduction: The growing trend of incidence of suffering and dying from endometrial
carcinoma, which has been registered across the world in recent years, is the reason why this
disease has become one of the major public health problems in the female population all over
the globe. The survival rate of those suffering from endometrial carcinoma is almost 90%,
while that percentage is drastically reduced if pelvic lymph nodes are positive to a metastatic
disease and amounts to around 50%. The studies have demonstrated that the incidence of
metastases in adenoids amounts to around 10% and highly depends on clinical,
pathoanatomical, and morphological characteristics of the actual disease. However,
lymphadenectomy in the treatment of patients suffering from the uterine cancer is the subject
matter of numerous debates at national and international conferences, which clearly points to
the fact that there is no consistent position concerning the importance of its role in the
therapeutic approach to this disease. Namely, numerous studies have indicated that the
incidence of serious complications in patients, who had been subjected to systematic
lymphadenectomy, is significantly higher compared to the groups of patients who had not been
subjected to this extensive surgical procedure. For this reason, a great number of studies have
been conducted for the purpose of identification of the most optimal method of selection of
patients who really need to be subjected to the systematic lymphadenectomy. In recent years, in
these terms, for the purpose of reduction of the postoperative morbidity, the role of the Sentinel
node lymphadenectomy - SLN in the assessment of the status of the pelvic lymphatic system in
the group of women suffering from endometrial carcinoma has been increasingly investigated.
Objectives: (I) Determining of SLN (Sentinel node lymphadenectomy) detection rate on the
sample of women in early stage of endometrial carcinoma; (II) Investigation of the value of the
rate of false negative findings, sensitivity, specifics, positive and negative predictive SLN
(Sentinel node lymphadenectomy) value in the assessment of the status of the pelvic lymph
nodes; (III) Comparison of histological findings of lymph nodes obtained using H&E
(hematoxylin and eosin) technique and other lymph nodes using supplementary ultra staging
technique - IHH (immunohistochemistry), when the H&E (hematoxylin and eosin) technique
has confirmed the absence of metastases; (IV) Investigation of the correlation between the
presence of metastases in SLN (Sentinel node lymphadenectomy) with the postoperative
histological finding and the degree of advancement of endometrial carcinoma..
Towards Efficient and Scalable Data-Intensive Content Delivery: State-of-the-Art, Issues and Challenges
This chapter presents the authors’ work for the Case Study entitled “Delivering Social Media with Scalability” within the framework of High-Performance Modelling and Simulation for Big Data Applications (cHiPSet) COST Action 1406. We identify some core research areas and give an outline of the publications we came up within the framework of the aforementioned action. The ease of user content generation within social media platforms, e.g. check-in information, multimedia data, etc., along with the proliferation of Global Positioning System (GPS)-enabled, always-connected capture devices lead to data streams of unprecedented amount and a radical change in information sharing. Social data streams raise a variety of practical challenges: derivation of real-time meaningful insights from effectively gathered social information, a paradigm shift for content distribution with the leverage of contextual data associated with user preferences, geographical characteristics and devices in general, etc. In this article we present the methodology we followed, the results of our work and the outline of a comprehensive survey, that depicts the state-of-the-art situation and organizes challenges concerning social media streams and the infrastructure of the data centers supporting the efficient access to data streams in terms of content distribution, data diffusion, data replication, energy efficiency and network infrastructure. The challenges of enabling better provisioning of social media data have been identified and they were based on the context of users accessing these resources. The existing literature has been systematized and the main research points and industrial efforts in the area were identified and analyzed. In our works, in the framework of the Action, we came up with potential solutions addressing the problems of the area and described how these fit in the general ecosystem

Spectrum Sensing Experimentation for LTE and WiFi Unlicensed Band Operation
If several different systems operate in the same frequency band, a coordination between them is needed for effective use of the available spectrum. The coordination is especially important if the systems are not designed to operate in such an environment. The very important initial phase of the coordination process is acquiring of the spectrum usage map or spectrum sensing. The paper describes the spectrum sensing experimentation in the unlicensed 5 GHz band during the WiFi or LTE transmission. It describes the experiment workflow and depicts the obtained results. The experiments were performed at NITOS testbed at the University of Thessaly, Greece, and show that it is possible to determine whether WiFi or LTE transmission is sensed. Therefore, based on spectrum sensing it will be possible to coordinate a shared access of WiFi and LTE users in the unlicensed 5 GHz band
