RESUMO

AIM: Essential Skills in the Management of Surgical Cases (ESMSC Marathon Course™) Integrated Generation 4 (iG4) is the first reported multifaceted undergraduate surgical course aiming to provide holistic surgical teaching. In this prospective observational study, we explored students' views on the iG4 curriculum, and identified how it can potentially address modern challenges in surgical training. MATERIAL AND METHODS: Medical students were invited to apply to the course online and were screened against pre-defined criteria. A multi-national structured questionnaire incorporating five domains related to the course curriculum and our dedicated research network, was designed and distributed to participants after successful completion of the course. RESULTS: Forty-one students from European and Asian medical schools completed the course and filled in the survey. The median overall evaluation score of the course was 4.73 out of 5 (interquartile range=4.21-4.72) and all students found that iG4 served the vision of holistic surgical education. ESMSC had a positive motivational effect towards following a career in surgery (p=0.012) and 92.7% of students declared that it should be an essential part of a future medical school curriculum. There was no statistically significant difference (p>0.05) in results between participants of different countries of study, year of studies or age group. CONCLUSION: The ESMSC Marathon Course™ is perceived as a unique course model, with an established educational value and a positive motivational effect towards surgery. It might potentially be implemented in future medical school curricula as an essential element of undergraduate surgical education. The iG4 curriculum has opened a new exciting horizon of opportunities for advancing undergraduate holistic surgical education.

RESUMO

Endometrial cancer (EC) is the most common cancer of the female genital tract, resulting annually in 76,000 related deaths worldwide. EC originates either from oestrogen-related proliferative endometrium (type I, endometrioid), or from atrophic endometrium (type II, non-endometrioid). Each type of EC is characterized by different molecular profile alterations. The Kirsten rat sarcoma viral oncogene homolog (KRAS) gene encodes a signalling protein which moderates response to various extracellular signals via down-regulation of the mitogen-activated protein kinase (MAPK) or phosphoinositide-3-kinase/v-akt murine thymoma viral oncogene (PI3K/AKT) pathways. This article reviews the role of KRAS in predicting transition from hyperplastic endometrium to early-stage well-differentiated EC, as well as further invasive proliferation of the tumour to advanced-stage disease. KRAS seems to be directly associated with type I EC, and most studies support its early involvement in carcinogenesis. Current evidence correlates KRAS mutations with increased cell proliferation and apoptosis, as well as up-regulation of endometrial cell oestrogen receptors. Tumours positive for KRAS mutation can harbour hypermethylation-related changes in genome expression, and this can be the cause of concurrent loss of DNA repair proteins. Despite some evidence that KRAS mutation status affects cancer progression, a consensus is yet to be reached. Based on the available evidence, we suggest that screening for KRAS mutations in patients with hyperplastic endometrium or early-stage type I EC, may provide important information for prognosis stratification, and further provision of personalised treatment options.
