RESUMEN
The Diffuse Large B-Cell Lymphoma is the most frequent non Hodgkin Lymphoma. The role of CT/PET in this relatively homogeneous group of lymphomas is controversial. It rarely changes the management of the patients in the initial staging. Recents publications, clinical trials and experts consensus meetings have demonstrated its utility in the evaluation of the response at the end of the treatment. The interest of CT/PET in the evaluation of the response during the treatment, with the objective of implement a "Risk Adapted Therapy", in increasing.

OBJECTIVES: Problem-Based Learning (PBL) is a teaching-learning technique centred on the complete development of the student. It has been successfully implemented in several universities, notably in the health sciences. The process of creating the European Higher Education Area, initiated in Bologna, encourages European universities to use new methodologies in the teaching-learning process, including PBL. Our objectives were to analyze the results obtained by using PBL with fifth-year Dentistry students. STUDY DESIGN: Comparison of academic results between students receiving lectures and PBL participants, and assessment of differences between them in the time devoted to tasks by students and teachers. RESULTS: PBL participants obtained higher grades compared to those receiving lectures only (p<0.05). The two student groups devoted the same amount of time to this subject but the time distribution of tasks was very different, with PBL students spending more time on group work and analysis of the literature. The teachers devoted much more time to the PBL group. CONCLUSIONS: PBL is a teaching-learning methodology that improves student academic results. PBL diverts student time to more complex tasks but requires a greater commitment from the teachers.
