This survey confirms that TMZ is established as first-line chemotherapeutic treatment of APT/PC. Clinically functioning tumours, low MGMT and concurrent radiotherapy were associated with a better response. The limited long-term effect of TMZ and the poor efficacy of other drugs highlight the need to identify additional effective therapies.

The receptor tyrosine kinase c-Met is an attractive target for therapeutic blockade in cancer.

Objective. To compare the prevalence of the main comorbidities in 2 large cohorts of patients with primary Sj€ ogren's syndrome (SS) and systemic lupus erythematosus (SLE), with a focus on cardiovascular (CV) diseases. Methods. This was a cross-sectional multicenter study where the prevalence of more relevant comorbidities in 2 cohorts was compared. Patients under followup from SJOGRENSER (Spanish Rheumatology Society Registry of Primary SS) and RELESSER (Spanish Rheumatology Society Registry of SLE), and who fulfilled the 2002 American-European Consensus Group and 1997 American College of Rheumatology classification criteria, respectively, were included. A binomial logistic regression analysis was carried out to explore potential differences, making general adjustments for age, sex, and disease duration and specific adjustments for each variable, including CV risk factors and treatments, when appropriate. Results. A total of 437 primary SS patients (95% female) and 2,926 SLE patients (89% female) were included. The mean age was 58.6 years (interquartile range [IQR] 50.0-69.9 years) for primary SS patients and 45.1 years (IQR 36.4-56.3 years) for SLE patients (P < 0.001), and disease duration was 10.4 years (IQR 6.0-16.7 years) and 13.0 years years), respectively (P < 0.001). Smoking, dyslipidemia, and arterial hypertension were associated less frequently with primary SS (odds ratio Conclusion. Primary SS patients have a consistently less serious CV comorbidity burden and a lower prevalence of severe infection than those with SLE. In contrast, their risk of lymphoma is greater.[

The GH receptor antagonist pegvisomant is an efficient agent to achieve biochemical control of acromegaly in those cases refractory to surgery and medical therapy with somatostatin analogs. We conducted an observational multicenter study consisting of data collection in accordance with the standard management of patients with acromegaly in everyday practice. We reviewed the medical records of 28 patients, 23 females, who were treated with pegvisomant due to the lack of biochemical response or intolerance to the somatostatin analogs. The objective was to monitor long-term safety and efficacy of the antagonist. 82% of the patients had previous pituitary surgery, 53.6% radiotherapy and 96.4% received medical therapy for acromegaly. Only 19.2% of the patients had pituitary residual tumor size larger than 1 cm, the remainder harbored a microadenoma or no visible tumor in the pituitary images. In terms of biochemical efficacy, IGF-I levels decreased to normal ranges in 45% and 58.8% of patients after 3 and 6 months of treatment, respectively, the daily mean dose of pegvisomant being 9.6+/-1.1 mg. Adverse events, potentially related to pegvisomant were reported in 6 patients (21.4%), local injection site reaction and elevated liver enzymes being the most frequent. Tumor size did not show enlargement in the evaluated population (15 patients) during the period of the study. This paper presents preliminary data from a small observational study in Argentina which represents the first database in our country.
