Why it is important to do this review
Several research studies on the use of music with cancer patients
have reported positive results (Beck 1989; Cassileth 2003; Harper
2001; Hilliard 2003; Robb 2008). The majority of these studies,
however, are compromised by small sample size and lack statistical
power. In addition, differences in factors such as study designs,
methods of interventions and type and intensity of treatment have
led to varying results. A systematic review is needed to more accurately
gauge the efficacy of music interventions for cancer patients
as well as to identify variables that may moderate its effects.
