 This study examined the role of health system capacity in influencing cancer survival rates in seven high-income countries. The researchers found that consolidated services and greater surgical specialization were important factors in improving cancer outcomes, but these improvements could only be achieved when accompanied by adequate staffing and supportive infrastructure. Additionally, the researchers noted that health system capacity must be considered in relation to the entire healthcare system, rather than an isolation.
