A report on the work of the radiologist, who has not been named, has found that his diagnoses were not checked by a second radiologist as the hospitals where he worked employed only one.

Last night cancer charities called on the Government to provide funding to ensure that all patients referred to hospital by their GP with suspected breast cancer had their scans double-checked as a matter of course.

When the radiologist was previously employed by another hospital, his work was checked by a colleague. The report found that in those cases there was no cause for concern.

The doctor was suspended by Trafford Healthcare NHS Trust in April last year after junior colleagues became concerned about the quality of his work and alerted hospital chiefs. The subsequent report, which is published today, identified serious shortcomings which resulted in the recall of 176 patients.

The delays caused by his misdiagnoses could have “significantly altered” chances of survival for 17 patients, a director at one of the hospitals affected said yesterday. One woman’s cancer was only noticed two years after the woman was informed that she did not have the disease. Another 16 patients seen by the radiologist at Trafford General and the North Manchester General, both in Greater Manchester, had their conditions misdiagnosed.

In total, 2,495 mammograms by the consultant at the centre of the investigation were recalled and rechecked. They dated from April 2003, when he joined the trust.

A small sample of his breast cancer tests were rechecked after concerns were raised. The doctor was suspended at once and checks of all his work carried out by an expert panel. The panel’s report states that, of the 176 patients who were recalled because of concerns, 28 women with breast disease were identified whose diagnosis had been delayed as a result of misreporting of their mammograms.

Twenty-five were patients from Trafford General Hospital and three from North Manchester General Hospital; 21 had invasive breast cancer diagnosed, six had benign breast disease and one had a treatable tumour.

Delays of more than three months for the diagnosis of breast cancer can have serious implications, but four of the 21 cases had delays less than that period. The remaining 17 had delayed diagnoses of longer than three months.

Richard Campbell, medical director at Trafford, said those patients have been told that the delayed diagnosis “might significantly alter their prognosis”.

Clara McKay, head of policy at Breast Cancer Care, the leading cancer charity, said that the situation highlighted the need for more radiologists who, where possible, could work in pairs to double-check work.

“The standard of all health professionals must be subject to ongoing review,” she said. “The acute UK-wide shortage of radiologists must be addressed to ensure reliable breast screening for all.”

Dr Campbell said the problem was first spotted by radio-graphers who questioned the radiologist’s X-ray work. All his radiology work was subsequently checked but his diagnoses in other areas gave “no significant concern”. No problems were reported in his earlier work at another trust, where all breast cancer radiology was double-checked.

The hospitals were at pains to point out that the recall of patients were women referred for the tests by their GP, not those routinely checked by national NHS breast screening.

The revelations come less than a week after the Government was urged to extend by ten years the period for automatic breast cancer screening for women. A Private Member’s Bill aims to extend raise the upper age limit to 75 and change the lower limit to 45. The current period is 50 to 70.
