Health: Cancer

Lord Saatchi Excerpts

Monday 20th May 2013 Lords Chamber

Asked By

[Lord Saatchi]

To ask Her Majesty’s Government in what proportion of deaths recorded as caused by cancer is the actual cause of death the treatment of cancer.

[The Parliamentary Under-Secretary of State, Department of Health (Earl Howe)]

The Office for National Statistics publishes national cancer mortality data annually. Data are collected where cancer has been recorded as the cause of death, but not on treatment for cancer as the cause of death. I therefore regret that I am unable to provide this information.

[Lord Saatchi]

My Lords, I thank my noble friend for that reply. The point of this Question is that there is no answer to it. Since I tabled the Question, I have received an estimate from within the medical profession that last year 15,000 people in Britain were killed by cancer treatment rather than by cancer. We do not know whether 1% or 100% of patients die as result of the treatment; what we do know is that cancer drugs do such damage to the immune system that the patient is helpless to resist fatal infections such as MRSA, E. coli or septicaemia. Does my noble friend agree, as I think he has, that the official statistics for the UK cannot distinguish between cancer death and treatment for cancer death? Is this not because the ONS, under WHO guidelines, records only the single underlying cause of death? In other words, it does not record the sequence of causation, sometimes known as the sequence of conditions, that led to the death. This is supposed to be the era of big data. Will my noble friend review the limitations of cancer mortality statistics in order to assist scientists and doctors to have the information to move forward innovation towards a cure for cancer?

[Earl Howe]

My Lords, I agree that it is important to have more information on the effect of cancer treatments on mortality. New data collections which will provide more detail in this area are under way. The systemic anti-cancer therapy dataset will enable better information to be collected about deaths after the delivery of chemotherapy, and the cancer outcomes and services data set will provide information in respect of death after surgical treatment. However, it is important to make one point here: it can be hard to identify the precise cause or sequence of progression of factors resulting in death, particularly for those with end-stage cancer or who are particularly frail and are experiencing physical deterioration. I do not think that it can ever be a precise science.
