BackgroundWilms tumour postoperative chemotherapy is ideally stratified according to the pathologist's assessment of tumour stage and risk classification (tumour type). In sub-Saharan Africa results are often not available in time to influence therapy and in Malawi surgical staging has been used to stratify postoperative chemotherapy. Here we compare the results from surgical and both local pathology and central pathology review.ProcedureChildren diagnosed with a Wilms tumour in Blantyre, Malawi between 2007 and 2011 were included if they had a nephrectomy and the pathology slides were available. All tumour specimens were assessed in three different ways: the local surgeon documented the surgical stage of the tumour, and the risk classification and pathology stage were assessed both by the local pathologist and by a SIOP central review pathologist in Europe.ResultsFifty patients had complete data available and were included in the analyses. Tumour risk classification differed between the local and central pathology review in only two patients (4%). Using central pathology review as the gold standard 60% of patients received the correct postoperative chemotherapy treatment based on surgical staging and 84% based on the local pathology stage and risk classification.ConclusionLocal pathology capacity building is needed to enable timely assessment and reporting.
