Introduction: At the moment at Medical Faculty, University of Sarajevo, simultaneously exist two systems of teaching process, the old (pre-Bologna) and Bologna process. Goal: To show efficiency and justification of use of Bologna process at Medical Faculty, University of Sarajevo, through the prism of actual beneficiaries of this process, students, assessment of quality of medical education, and comparison of results of the teaching process evaluation between students studying according to the Bologna process and the old system. Materials and Methods: The study included period from 2012 to 2014, and had prospective character. Students of final (sixth) year were included, the last three generations of pre-Bologna, and three generations of the Bologna process, which completed their studies successfully. The study included 365 students (177 under the old system and 188 under the Bologna process), who had answered prepared questionnaire. Results: The presence of large number of female students, in both systems is significant. There were significant differences in opinion of students regarding the quality of space for administration and labor administration, informatization of the teaching process, the opinion of the objectivity of teachers in the assessment of the examination, and on-line access to their content. (p <0.05). Discussion: The Bologna process, with all its guidelines, was never to the maximum implemented in the teaching faculties, mostly because of the lack of funds and infrastructure that couldn’t fully comply with all the privileges of the Bologna process. Conclusion: Bologna process on this principle, has brought mediocrity, of which we have tried to escape. New school year, brings, and the new Bologna process, a new curriculum, a large number of new classes, systematization of the material, with simultaneous correction necessary in one hand in teaching, and in other hand in students themselves.

Introduction: the most important factor regarding the survival of patients with non-small cell lung cancer (NSCLC) is the mediastinal lymph node status. The influence of several factors on the occurrence of N1 and N2 metastases was investigated, the most common being lung cancer, tumor size, and the degree of differentiation of tumor cells. Aim: to determine the association between the degree of tumor cells (G stage) differentiation and the presence of peritumoral lymphatic infiltration (PTLI) with the occurrence of N1 and N2 metastases in NSCLC. Materials and methods: the study included a sample of 331 patients, of all ages, both genders, who underwent a complete resection of previously diagnosed lung cancer. Surgery was performed under general anesthesia technique employing a Carlens tube, with the prior zonal exploration of mediastinal lymph nodes and/or thoracoscopic exploration of the pleural cavity. The peritumoral compartment in which lymphocytic infiltration was investigated is an area around the intratumoral compartment that includes the edge of the tumor and a width of 1 mm beyond it. Results: the most common type of lung cancer among patients in this study was adenocarcinoma, with PTLI in more than 69% of cases. There is a 3,5 times higher risk of developing N disease when there is PTLI comparing with cases when there is none. PTLI was present in 86 (37.6%) patients with N0 disease, 128 (55.9%) patients with N1 disease, and 15 (6.6%) patients with N2 disease. Conclusion: the presence of PTLI is significantly associated with the occurrence of N1 and N2 metastases in patients with NSCLC.
