Objective To systematically review the global situation of off-label drug use in cancer patients. Methods We searched PubMed, EMbase, CNKI, CBM and VIP databases from their inception to October 2014, to collect studies on off-label drug use in cancer patients. The publication language was limited to English and Chinese. Combieg criteria was used for methodological quality assessment of included studies. A describe analysis was used to analyze the incidence and the proportion of different off-label used drugs. Results A total of 14 cross-sectional studies were included. Among them, 1 was from Switzerland, 1 was from Italy, 1 was from Australia, and the other 11 studies were from China. Seven included studies reported the investigated patients' number, containing 3 713 cancer patients and 13 238 prescriptions. The incidences of off-label drug were 2 844, accounting for 21.48%. There were similar rates of off-label prescriptions in Europe, Asia and Australia, but the average off-label prescriptions of European cancer patients were lower than Asia and Australia. The total rate of "unapproved dose", "unapproved indication", and "unapproved solvents" were more than 80% in off-label drug use. Conclusion The average off-label prescriptions of European cancer patients are lower than Asian and Australian. "Unapproved dose", "unapproved indication" and "unapproved solvents" are the most common off-label prescription in off-label drug use.
