Review Meta Analysis
Use of trastuzumab in HER2-positive metastatic breast cancer beyond disease progression: a systematic review of published studies.
Trastuzumab, a humanized monoclonal antibody directed against the extracellular domain of ErbB, has determined clinical benefit for women affected by metastatic or early stage HER2-positive breast cancer and never previously treated with trastuzumab. Trastuzumab is generally used as first-line treatment of HER2+ metastatic breast cancer and is currently administered beyond progression even without clear evidence supporting such clinical practice. In fact, HER2-positive metastatic breast cancer has a high risk of progressing after first-line therapy, and second-line treatments vary. The aim of the study was to investigate by a systematic review the efficacy of trastuzumab-based treatments beyond progression in HER2-positive metastatic breast cancer. ⋯ The added value of the present study has been to provide a quantitative summary measure of time to progression which can be used for comparisons between current and future available regimens.

The aggressiveness of cancer care near the end of life and the consumption of opioids are potential indicators of quality of care in palliative and end-of-life settings. The purpose of this article is to present a retrospective analysis regarding these themes and the adopted procedures to improve quality of care. ⋯ To reduce the administration of chemotherapy near the end of life, we introduced the palliative prognostic score, to be administered to all advanced cancer patients with performance status of at least 2. To evaluate the effectiveness of analgesics and to reduce the cases of undertreatment of cancer pain, we adopted, in addition to the numerical rating scale, Cleeland's Pain Management Index. We are convinced that attempts to improve the quality of care can be achieved by the collaboration of all health professionals, patients and care givers.
