The clinical effectiveness of trastuzumab for breast cancer: a systematic review.

Searching MEDLINE, EMBASE, Cancerlit, BIOSIS Previews, the Index to Scientific and Technical Proceedings, the Cochrane Controlled Trials Register, DARE, NHS EED and the National Research Register were searched to August 2001; the search terms and strategies were reported in depth. The authors identified additional references through reviewing submissions (to the National Institute of Clinical Excellence) by manufacturers, by checking the bibliographies of retrieved articles, and by searching conference proceedings and the Internet. Studies reported in English, German, Dutch and French were eligible for inclusion in the report, but the search strategy had no language restrictions.
