ReviewEfficacy and safety of palliative chemotherapy for patients with advanced breast cancer pretreated with anthracyclines and taxanes: a systematic review.
No standard monotherapy or combination palliative chemotherapy currently exists for patients with advanced breast cancer pretreated with anthracyclines and taxanes. In this systematic review we assess the current knowledge on the efficacy and safety of palliative single-agent chemotherapy drugs--capecitabine, vinorelbine, gemcitabine, and liposomal doxorubicin--commonly used in daily clinical practice. We identified 22 studies, of which ten investigated capecitabine, nine investigated vinorelbine, three investigated gemcitabine, and one investigated liposomal doxorubicin. ⋯ These two drugs showed good efficacy. The disease control rate differed significantly between the four drugs, which is relevant in terms of how well tumour symptoms can be improved and whether quality of life can be maintained or even improved. To obtain more evidence of the efficacy and safety of chemotherapeutic agents used in this pretreated population of advanced breast cancer patients, randomised comparisons of the various drugs, as monotherapy and in combination with targeted agents, are needed.

Effect of crizotinib on overall survival in patients with advanced non-small-cell lung cancer harbouring ALK gene rearrangement: a retrospective analysis.
ALK gene rearrangement defines a new molecular subtype of non-small-cell lung cancer (NSCLC). In a recent phase 1 clinical trial, the ALK tyrosine-kinase inhibitor (TKI) crizotinib showed marked antitumour activity in patients with advanced, ALK-positive NSCLC. To assess whether crizotinib affects overall survival in these patients, we did a retrospective study comparing survival outcomes in crizotinib-treated patients in the trial and crizotinib-naive controls screened during the same time period. ⋯ Pfizer Inc, V Foundation for Cancer Research.

Intrauterine device use, cervical infection with human papillomavirus, and risk of cervical cancer: a pooled analysis of 26 epidemiological studies.
Intrauterine device (IUD) use has been shown to reduce the risk of endometrial cancer, but little is known about its association with cervical cancer risk. We assessed whether IUD use affects cervical human papillomavirus (HPV) infection and the risk of developing cervical cancer. ⋯ Instituto de Salud Carlos III; Agència de Gestió d'Ajuts Universitaris i Recerca; Marató TV3 Foundation; Bill & Melinda Gates Foundation; International Agency for Research on Cancer; European Community; Fondo de Investigaciones Sanitarias, Spain; Preventiefonds, Netherlands; Programa Interministerial de Investigación y Desarrollo, Spain; Conselho Nacional de Desenvolvimiento Cientifico e Tecnologico, Brazil; and Department of Reproductive Health & Research, WHO.
