Metastatic involvement of optic nerve in patient with breast and lung neoplasia.

Metastases are the most common adult intraocular tumors. However, those located in the optic nerve are very uncommon and are usually associated with spread to other locations such as the central nervous system, which darkens the prognosis. There is a case of a 67-year-old woman who reports progressive vision loss in the right eye of 15 days of evolution.

The impact of participatory teaching methods on medical students' perception of their abilities and knowledge of epidemiology and statistics.

Statistics and Epidemiology are crucial both in clinical decision-making and clinical research. Teaching these disciplines in a Bachelor's Degree in Medicine is a significant challenge. In this paper, we aim to describe two participatory teaching methods used in a yearlong second-year course that includes both Epidemiology and Statistics, and to analyze how these two methodologies affect the students' perception of the course and their abilities related to these subjects.

Low RAP80 mRNA expression correlates with shorter survival in sporadic high-grade serous ovarian carcinoma.

Objective: Homologous recombination (HR) is frequently impaired in sporadic high-grade serous ovarian carcinoma (sHGSOC) due to deficiencies in BRCA1/2 genes, a situation associated with hypersensitivity to platinum compounds. Alterations in other genes can also cause HR deficiency. Preclinical data show that RAP80 is an HR-pathway-related gene that influences BRCA1 activity.

Two biomarker-directed randomized trials in European and Chinese patients with nonsmall-cell lung cancer: the BRCA1-RAP80 Expression Customization (BREC) studies.

Background: In a Spanish Lung Cancer Group (SLCG) phase II trial, the combination of BRCA1 and receptor-associated protein 80 (RAP80) expression was significantly associated with outcome in Caucasian patients with nonsmall-cell lung cancer (NSCLC). The SLCG therefore undertook an industry-independent collaborative randomized phase III trial comparing nonselected cisplatin-based chemotherapy with therapy customized according to BRCA1/RAP80 expression. An analogous randomized phase II trial was carried out in China under the auspices of the SLCG to evaluate the effect of BRCA1/RAP80 expression in Asian patients.
