The Preoperative Assessment of Hepatic Tumours : Evaluation of UK Regional Multidisciplinary Team Performance

الملخص EN

Introduction.

In the UK, patients where liver resection is contemplated are discussed at hepatobiliary multidisciplinary team (MDT) meetings.

The aim was to assess MDT performance by identification of patients where radiological and pathological diagnoses differed.

Materials and Methods.

A retrospective review of a prospectively maintained database of all cases undergoing liver resection from March 2006 to January 2012 was performed.

The presumed diagnosis as a result of radiological investigation and MDT discussion is recorded at the time of surgery.

Imaging was reviewed by specialist gastrointestinal radiologists, and resultswereagreedonby consensus.

Results.

Four hundred and thirty-eight patients were studied.

There was a significant increase in the use of preoperative imaging modalities (P≤0.01) but no change in the rate of discrepant diagnosis over time.

Forty-two individuals were identified whose final histological diagnosis was different to that following MDT discussion (9.6%).

These included 30% of patients diagnosed preoperatively with hepatocellular carcinoma and 25% with cholangiocarcinoma of a major duct.

Discussion.

MDT assessment of patients preoperatively is accurate in terms of diagnosis.

The highest rate of discrepancies occurred in patients with focal lesions without chronic liver disease or primary cancer, where hepatocellular carcinoma was overdiagnosed and peripheral cholangiocarcinoma underdiagnosed, where particular care should be taken.

Additional care should be taken in these groups and preoperative multimodality imaging considered.
