How to read these charts
Against the national standards
Each measure is drawn against its own NHS England standard: 95% for A&E within four hours, 85% for urgent cancer treatment within sixty-two days and 99% for diagnostic tests within six weeks. The charts do not share a standard and the three cancer measures are never added together.
Care Quality Commission
When CQC last rated this body
CQC has not rated The Royal Marsden NHS Foundation Trust since 16 January 2020. Its judgements from then are still on CQC’s own site and are not shown here, because a rating more than 3 years old is not what CQC currently says about a body.

One measure is marked as not reported. NHS England publishes each of these against the providers that deliver the service, so an absence is usually the kind of body rather than a figure we have failed to collect.
