Fulvestrant is a selective estrogen receptor downregulator, behaving as a complete antagonist. It was initially approved, at a dose of 250. mg, to treat hormone dependant breast cancer in second line setting. However, a series of pharmacological and pre-clinical studies have suggested that a higher dose of 500. mg may be more effective. The present work summarizes and discusses clinical trials that have aimed to test the benefits of administering fulvestrant at a higher dose. The data support the use of a higher, and more possibly, effective dose of the agent. © 2012 Elsevier Ltd. Source

Background: Skin rash is an adverse event which might be associated with longer survival in patients treated with epidermal growth factor receptor tyrosine kinase inhibitors. The aim of this nonrandomised phase II clinical trial is to prospectively evaluate the relationship between skin rash and overall survival (OS) in advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine. Patients and methods: Patients were given gemcitabine (1000 mg/m. 2/week, 3 weeks every 4 weeks) plus erlotinib (100 mg/day orally continuously) until disease progression/unacceptable toxicity. The primary end point was OS. Results: A total of 153 eligible patients were enrolled (grade ≥ 2 rash, 25%; grade < 2 rash, 75%). OS was longer in patients with grade ≥2 rash versus grade <2 (11 versus 5 months; P < 0.001). Progression-free survival was longer in patients with grade ≥2 rash versus grade <2 (6 versus 3 months; P < 0.001) and shorter in those without rash versus grade 1 (2 versus 4 months; P = 0.005) or grade ≥2 (2 versus 6 months; P < 0.001). Patients with grade ≥2 rash showed higher rates of overall response (21% versus 7%; P < 0.05) and disease control (84% versus 43%; P < 0.05) versus grade <2. Conclusions: This study prospectively confirms the relationship between rash and longer OS in unresectable locally advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine. © The Author 2011.

In spite of recent advances in the treatment of metastatic breast cancer, this disease remains essentially incurable. Anthracyclines and taxanes have been widely demonstrated to be the most active cytotoxic drugs for the treatment of breast cancer. Paclitaxel and docetaxel are both hydrophobic drugs that need to be administered with detergent-like substances as solvents. In contrast, nanoparticle albumin-bound (nab) paclitaxel uses the natural characteristics of albumin to reversibly bind paclitaxel, transport it across endothelial cells and concentrate the active ingredient within the tumor. Several trials have demonstrated that nab-paclitaxel results in superior efficacy, with more complete responses, prolonged time to recurrence and survival, than paclitaxel and docetaxel in MBC. As second-line treatment, the novel formulation has almost doubled overall response rate, increased time to progression and overall survival in comparison with paclitaxel. Due to these results, to date nab-paclitaxel stands out as a promising treatment of metastatic breast cancer. © 2013. Source

Background & Aims: We aimed at comparing overall and liver-related mortality rates, observed in HIV positive subjects followed-up in the Cohorts of Spanish Network on HIV/AIDS Research stratified by HCV co-infection status, with the expected mortality of the general population of same age and sex in Spain, for the period 1997 - 2008. Methods: We estimated standardized mortality ratio (SMR) and excess mortality, comparing death rates from our cohort (globally and by HCV co-infection) with death rates from the general population standardized by sex in 5 year-age bands. Results: Overall, 5914 HIV positive subjects were included, 37.3% of which were co-infected with HCV; 231 deaths occurred, 10.4% of which were liver-related. SMR for all causes mortality for the HIV positive subjects was 5.6 (CI 95% 4.9-6.4), 2.4 (1.9-3.1) for HCV negative subjects and 11.5 (9.9-13.4) for HCV positive ones. Having HCV co-infection and AIDS yielded an SMR of 20.8 (16.5-26.1) and having AIDS and being HCV negative had an SMR of 4.8 (3.5-6.7). SMR for liver-related mortality was 1.8 (0.6-5.7) for HCV negative subjects vs. 22.4 (14.6-34.3) for HCV positive ones. Overall, both mortality rates as SMR and excess mortality rates were higher for injecting drug users (IDUs) than men having sex with men (MSM) and heterosexuals, patients with AIDS, with and without cART and for subjects included between 1997 and 2003. Conclusions: There was an excess of all-cause and liver-related mortality in our cohorts compared with the general population. Furthermore, HCV co-infection in HIV positive patients increased the risk of death for both all causes and liver-related causes. © 2012 European Association for the Study of the Liver.
